CROSS REFERENCE TO THE RELATED APPLICATIONS

This application is based upon and claims priority to Chinese Patent Application No. 202422140419.9, filed on Sep. 2, 2024, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to the field of artificial branch technologies, and in particular to an adjustable artificial branch and an injection mold.

BACKGROUND

An artificial branch is an artificial product that is manufactured using technological means for simulating an appearance and a texture of a real branch. These artificial branches are widely used in various ornaments and landscape designs.

It is retrieved that a patent with an application NO. CN202023194463.6 discloses an artificial branch and an injection mold for processing the artificial branch. The artificial branch includes a trunk and a plurality of leaves. The leaf includes a twig and a vane connected to the twig. One end of the twig is integrally injection-molded in the trunk. A connection position of each twig surrounds a circumferential side of the trunk. The injection mold includes a first molding board and a second molding board. When the mold is closed, the first molding board and the second molding board form a mold cavity. The mold cavity includes a primary cavity and a secondary cavity that communicates with the primary cavity. A connection position of each secondary cavity surrounds a circumferential side of the primary cavity. An insertion hole which communicates with an end part of the secondary cavity is provided on the first molding board and/or the second molding board, and the insertion hole is configured to insert an end part of the twig. According to the mold in the solution, the end part of the leaf is integrally formed in the trunk, so that the artificial branch is more stable in structure. In addition, the leaves surround the trunk with a range of 360°, are more orderly, and better in visual effect.

Skin of the trunk of the artificial branch in the solution is integrally injection-molded, and then the leaves are inserted into the trunk. However, the leaves are not adjustable in position and angle after being inserted. After the leaves are inserted, if density of the leaves on the trunk is uneven (that, there are gaps among the leaves), the aesthetics of the artificial branch are affected, and therefore, an adjustable artificial branch and an injection mold need to be disclosed.

SUMMARY

An objective of the present invention is to provide an artificial branch and an injection mold. An angle adjustment mechanism and a height adjustment mechanism are designed, so that after leaves are inserted into the trunk, positions and angles of the leaves can be adjusted according to a density of the leaves and a gap condition among the leaves. In other words, after the leaves are inserted, the leaves not only can be adjusted through auto-rotation, but also all leaves on a same skin layer can be rotated through the angle adjustment mechanism. In addition, height of the leaves on a same outer skin layer can be further adjusted through the height adjustment mechanism, to avoid that the inserted leaves are stacked together or a large gap exists between adjacent leaves. This ensures density uniformity of the leaves, and therefore, the manufactured artificial branch is more aesthetic, to address the technology issues raised in the background.

To achieve the objective, the present invention provides the following technical solution: An adjustable artificial branch includes a trunk and a plurality of leaves which are inserted into the trunk, where the leaf includes a twig and a vane connected on the twig; one end of the twig is injection-molded on the trunk; and an angle adjustment mechanism and a height adjustment mechanism for twig position adjustment are arranged on a connection position of the twig and the trunk.

Preferably, the trunk includes a metal core and a plurality of skin layers wrapped on an outer wall of the metal core, where the angle adjustment mechanism includes a sleeve that is rotatably mounted on the skin layer, and a positioning assembly for locking the twig on a needed rotation angle is arranged on the sleeve.

Preferably, a mounting hole is provided on the skin layer, the positioning assembly includes a spring that is connected on the outer wall of the metal core and is positioned inside the mounting hole, and one end of the spring is connected to a limiting ball.

Preferably, a plurality of through holes are provided at an upper end and a lower end of a side wall of the sleeve at an annular equal spacing, and one end of the limiting ball passes through the mounting hole and then is clamped into one through hole.

Preferably, an annular limiting slot is provided on an inner wall of the sleeve, a limiting ring is mounted on an outer wall of the skin layer, and the limiting ring is slidably mounted inside the limiting slot.

Preferably, the twig includes a convex base that is disposed in an inclined manner, a V-shaped insertion base is rotatably mounted on an end part of the convex base, a first circular ring is mounted on an inner wall of the end part of the convex base, a second circular ring is mounted on a bottom of the V-shaped insertion base, and the second circular ring is rotatably mounted inside the first circular ring.

Preferably, the height adjustment mechanism includes a C-shaped bar fastened on an outer wall of the sleeve, and a connecting plate mounted on the other end of the convex base, where first positioning blocks are vertically arranged on an inner wall of the C-shaped bar at equal spacings.

Preferably, fastening blocks are mounted on two sides of the connecting plate, a second positioning block is mounted on the fastening block, and the second positioning block is clamped between two adjacent first positioning blocks.

Preferably, both the first positioning block and the second positioning block are hemispheric positioning blocks, and both the first positioning block and the second positioning block are silicone rubber blocks that are capable of deforming.

The present invention further provides an injection mold for an adjustable artificial branch. The injection mold is used for injection-molding the adjustable artificial branch, and includes a trunk mold for injection-molding a skin layer of the trunk, and a leaf mold for injection-molding leaves, where a mold cavity that fits a convex base and a V-shaped insertion base in the twig and a vane shape is arranged inside the leaf mold.

Compared with the prior art, the present invention has the following beneficial effects.

The angle adjustment mechanism and the height adjustment mechanism are designed, so that after leaves are inserted into the trunk, positions and angles of the leaves can be adjusted according to a density of the leaves and a gap condition among the leaves. In other words, after the leaves are inserted, the leaves not only can be adjusted through auto-rotation, but also all leaves on a same skin layer can be rotated through the angle adjustment mechanism. In addition, height of the leaves on a same outer skin layer can be further adjusted through the height adjustment mechanism, to avoid that the inserted leaves are stacked together or a large gap exists between adjacent leaves. This ensures density uniformity of the leaves, and therefore, the manufactured artificial branch is more aesthetic.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The following clearly and completely describes the technical solutions the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only some but not all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of this application.

Refer to FIG. 1 to FIG. 3. The present invention provides a technical solution: An adjustable artificial branch includes a trunk and a plurality of leaves which are inserted into the trunk. The leaf includes a twig 4 and a vane connected on the twig 4; one end of the twig 4 is injection-molded on the trunk; and an angle adjustment mechanism 3 and a height adjustment mechanism 5 for position adjustment of the twig 4 are arranged on a connection position of the twig 4 and the trunk.

In use, the angle adjustment mechanism 3 is configured to adjust the twig 4 to integrally rotate in the horizontal direction, that is, change the position of the twig in the horizontal direction, to fill a gap between twigs 4 at a same height.

The height adjustment mechanism 5 is configured to adjust height of the twigs 4 on the same skin layer 2. In addition, the plurality of twigs 4 can be separately adjusted to adjust mounting density of the twigs 4, and vertically move the twigs 4 stacked together to positions with gaps, so that mounting uniformity of the twigs 4 is ensured.

The trunk includes a metal core 1 and a plurality of skin layers 2 wrapped on an outer wall of the metal core 1. A main body of the trunk is the metal core 1, so that strength of the trunk can be improved. The angle adjustment mechanism 3 includes a sleeve 31 that is rotatably mounted on the skin layer 2, and a positioning assembly for locking the twig 4 on a needed rotation angle is arranged on the sleeve 31. That is, the sleeve 31 is rotated to drive the plurality of twigs 4 to horizontally rotate by a specific angle, and then the positioning assembly can be configured to lock the twigs on positions to which the twigs are moved, to prevent the twigs from deflecting.

The plurality of twigs 4 are distributed on each skin layer 2 at annular equal spacings.

A mounting hole 21 is provided on the skin layer 2, the positioning assembly includes a spring 23 that is connected on the outer wall of the metal core 1 and is positioned inside the mounting hole 21, and an end of the spring 23 is connected to a limiting ball 24.

A plurality of through holes 33 are provided at an upper end and a lower end of a side wall of the sleeve 31 at an annular equal spacing, and an end of the limiting ball 24 passes through the mounting hole 21 and then is clamped into one through hole 33.

The limiting ball 24 is pressed, and the limiting ball 24 exits the through hole 33 to release limiting on the sleeve 31. Then, the sleeve 31 is rotated by a needed angle, and the limiting ball 24 is aligned to another through hole 33, and the limiting ball 24 is released, so that the limiting ball 24 enters the through hole 33 under effect of elastic force of the spring 23 for locking the sleeve 31 again. In this way, the position of the angle-adjusted twig 4 is locked.

An annular limiting slot 32 is provided on an inner wall of the sleeve 31, a limiting ring 22 is mounted on an outer wall of the skin layer 2, and the limiting ring 22 is slidably mounted inside the limiting slot 32, so that stability in a rotation process of the sleeve 31 is ensured.

The twig 4 includes a convex base 41 that is disposed in an inclined manner, an included angle between the convex base 41 and the trunk is smaller than 30 degrees, a V-shaped socket 42 is rotatably mounted on an end part of the convex base 41, an included angle between two twigs for connecting vanes on the V-shaped insertion base 42 is smaller than 30 degrees. That is, an included angle between the vane and the twig that are mounted is smaller than 60 degrees. A first circular ring 43 is mounted on an inner wall of the end part of the convex base 41, a second circular ring 44 is mounted on a bottom of the V-shaped insertion base 42, and the second circular ring 44 is rotatably mounted inside the first circular ring 43. The V-shaped insertion base 42 is rotated to adjust a vane mounting angle and achieve vane mounting variety.

The height adjustment mechanism 5 includes a C-shaped bar 51 fastened on an outer wall of the sleeve 31, and a connecting plate 53 mounted on the other end of the convex base 41. The connecting plate 53 is movably mounted inside the C-shaped bar 51, and first positioning blocks 52 are vertically arranged on an inner wall of the C-shaped bar 51 at equal spacings.

Fastening blocks 54 are mounted on two sides of the connecting plate 53, a second positioning block 55 is mounted on the fastening block 54, and the second positioning block 55 is clamped between two adjacent first positioning blocks 52.

When the height of the twig 4 needs to be adjusted, the position of the connecting plate 53 inside the C-shaped bar 51 can be vertically adjusted to drive the twig 4 and the vane to move vertically. In this way, the twigs 4 stacked together can be moved to positions with gaps, to ensure mounting uniformity of the twigs 4.

Both the first positioning block 52 and the second positioning block 55 are hemispheric positioning blocks, and both the first positioning block 52 and the second positioning block 55 are silicone rubber blocks that are capable of deforming. In other words, the first positioning block 52 is locked by two second positioning blocks 55. When the connecting plate 53 is moved, the first positioning block 52 squeezes the second positioning block 55, and both the first positioning block 52 and the second positioning block 55 deform until the first positioning block 52 is moved to a position between another two second positioning blocks 55.

The present invention further provides injection mold for an adjustable artificial branch. The injection mold is used for injection-molding the adjustable artificial branch, and includes a trunk mold for injection-molding a skin layer 2 of a trunk, and a leaf mold for injection-molding leaves, where a mold cavity that fits a convex base 41 and a V-shaped socket 42 in the twig 4 and a vane shape is arranged inside the leaf mold.

Although the embodiments of the present invention are shown and described, for a person of ordinary skill in the art, various changes, modifications, replacements, and variations may be made to the embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is as defined by the appended claims and their equivalents.
