DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will be further described below in conjunction with the accompanying drawings and embodiments.

Embodiment 1, as shown in FIG. 1-3, presents a hanging bracket including a fixing strip 1, a fixing bracket 2, an elastic hook 3, and a fastening device 4. The fixing strip 1 is provided with a first mounting hole 11, a second mounting hole 12, and a guide hole 13 along the length direction. In this embodiment, the fixing strip 1 is provided with second mounting holes 12 at both ends, and a guide hole 13 is provided between the second mounting holes 12 at both ends. The first mounting hole 11 is provided between the two ends of the guide hole 13 and the second mounting hole 12. The guide hole 13 is a waist circular hole.

A slider 21 is provided at the center position of fixing frame 2, the slider 21 is internally designed with a through hole 22, the two sides of the fixing frame 2 are bent upwards to form a groove 23 with open ends on the top surface of the fixing frame 2. Slider 21 is inserted into guide hole 13, and slides in guide hole 13 along with fixing bracket 2. The fixing strip 1 is placed inside the groove 23, and both ends of the fixing strip 1 extend from the end of groove 23, and the fixing bracket 2 slides relative to the fixing strip 1 through the groove 23, that is, the fixing strip 1 and fixing bracket 2 fit well in a limit position in the width direction of the fixing strip 1. The bottom surface of fixing bracket 2 is provided with a positioning protrusion 24.

The fixing bracket 2 and fixing strip 1 are connected through a fastening device 4 that passes through the guide hole 13, and the fastening device 4, when released, drives the fixing bracket 2 to slide inside the guide hole 13, causing the fixing bracket 2 to slide relative to the fixing strip 1, and when the fastening device 4 is locked, the positions of the fixing bracket 2 and fixing strip 1 are relatively fixed.

The elastic hook 3 includes a base 31 and elastic arms 32 located on both sides of the base 31, the two elastic arms 32 are symmetrically arranged axially, and a hook portion 33 is provided on the side where the elastic arms 32 are separated from each other. The two sides of the base 31 bend downwards to form the elastic arms 32, and the ends of the two elastic arms 32 bend towards the opposite side to form a hook portion 33, the end of hook portion 33 bends downwards towards the opposite side to form an inclined stretching portion 34, and the end of stretching portion 34 bends towards the opposite side to form an inclined pressing portion 35, and the two pressing portions 35 that move towards each other can drive the stretching portion 34 to pull the two hook portions 33 closer, so that the range hood can be easily dismantled. Preferably, the elastic hook 3 is integrally stamped and bent into shape. The angle between hook 33 and elastic arm 32 is less than or equal to 90°.

The base 31 is provided with a connecting hole 36 and a positioning hole 37. The positioning protrusion 24 that is insert into the positioning hole 37 can make the fixing bracket 2 and base 31 limit each other. The fastening device 4 passes through the connecting hole 36 to connect the base 31 and fixing bracket 2 together. Specifically, the fastening device 4 includes a bolt 41 and a nut 42, the screw of the bolt 41 passes through the guide hole 13, through hole 22, and connecting hole 36 sequentially from the bottom and is threaded to the nut 42.
