The following description is provided to disclose the present disclosure to enable those skilled in the art to implement the present disclosure. The preferred embodiments in the following description are given by way of example only and other obvious modifications will occur to those skilled in the art.

As shown in FIG. 1, the embodiments of the present application disclose a tool table convenient for folding, including a table plate body 100 and foldable support legs 200 mounted at the bottom of the table plate body 100. In a use state of the tool table, the support legs 200 located at two sides of the table plate body 100 are vertically parallel, and optimally the support legs 200 at the two sides are of an “” shape, thereby ensuring a stable support force and stably supporting the table plate body 100. In a non-use state of the tool table, the support legs 200 at the two sides are simultaneously folded towards the center of the bottom of the table plate body 100, thereby facilitating accommodation of the tool table and reducing the space occupied thereby. The table plate body 100 is of a rectangular plate shape, and a blind groove is provided on an upper surface thereof for placing debris, in which the blind groove includes a groove opening for receiving falling wood chips, a groove opening for placing manual tools and a groove opening for placing an accessory. A scale 120 is further provided on the upper surface of the table plate body 100, and the scale 120 and the table plate body 100 can have an integrated structure, preferably the scale is carved on the upper surface of the table plate body 100, and may also be an existing scale, which is fixed on the surface of the table plate body 100 by means of bolts, adhesives or rivets, so as to facilitate a processing operation of a workpiece; and a handle may also be provided on a side surface of the table plate body 100, so that the table is placed and taken after being folded. As shown in FIG. 2, a concave accommodating cavity 110 is formed at the bottom of the table plate body 100, two parallel rotating shafts 300 are fixedly mounted in the accommodating cavity 100, an end of each of the support legs 200 is provided on the periphery of a rotating shaft 300 at a corresponding side, and the support legs 200 rotate relative to the rotating shafts 300 at the corresponding sides, so that the support legs 200 are unfolded or folded. Each rotating shaft 300 is provided with two support legs 200, a connecting plate 800 is riveted between the two support legs 200, and two ends of the connecting plate 800 are respectively fixedly connected to the support legs 200 at the corresponding sides.

As shown in FIG. 3A-3C, straight racks 400 are provided on the outer peripheries of the rotating shafts 300, the straight racks 400 extend towards the rotating shaft 300 at the opposite side, and in order to reach the position of the rotating shaft 300 at the opposite side, the two straight racks 400 are provided in parallel and the sawteeth thereof are opposite, gears 500 are provided between the sawteeth of the two straight racks 400, the outer peripheries of the gears 500 are engaged with the sawteeth of the straight racks 400, and the support legs 200 operate steadily during the unfolding or folding process, thereby reducing a sense of weightlessness. A positioning cylinder 111 having a vertically downward hollow structure is formed on a top wall of the accommodating cavity 110, the gears 500 are sleeved on the outer periphery of the positioning cylinder 111, the two are coaxial, and when the support legs 200 move, the gears 500 rotate around the outer wall of the positioning cylinder 111. Here, the top wall is relative to the table in a normal use state.

In order to avoid the falling problem of the straight racks 400 and the gears 500 under the action of gravity, a blocking plate 600 is provided below the gears 500, the blocking plate 600 is fixedly connected to the top wall of the accommodating cavity 110 by means of a fixing component such as bolts or screws, a guiding anti-falling cavity for accommodating the gear transmission structure is formed therebetween, a movable gap is reserved between the top surface of the blocking plate 600 and the gears 500, and the guiding anti-falling cavity not only positions the gears 500 and the straight racks 400 in the longitudinal direction, thereby avoiding falling, but also does not interfere with the two, thereby ensuring the smooth transmission of the two.

As shown in FIG. 5A and FIG. 5B, in order to keep the position of the support legs 200 in the folded state fixed, knobs 610 are connected to the bottom surface of the blocking plate 600. The two support legs 200 are folded towards the middle, edges of connecting plates 800 on two sides are respectively located at two sides of the knobs 610, the knobs 610 are rotated by 90 degrees, two ends of each of the knobs 610 respectively clamp the edges of the connecting plates 800 on the corresponding sides, so that the positions of the support legs 200 are limited, and when the tool table is moved, the support legs 200 do not fall downwards due to the action of gravity. In order to better clamp the connecting plates 800 by the knobs 610, an edge of a connecting plate 800 close to a knob 610 is thinner than an edge of the connecting plate 800 away from the knob 610.

As shown in FIGS. 3C and 4, the two rotating shafts 300 are further respectively provided with reinforcing rods 700 arranged opposite to each other, the distal end of each reinforcing rod 700 is provided with a clamping groove 710 for clamping the corresponding rotating shaft 300 on the corresponding side, the clamping groove 710 opens downwards, a portion of the outer peripheral surface of the rotating shaft 300 is embedded in the clamping groove 710, so as to provide a supporting force for the rotating shaft 300, reduce the deformation of the rotating shaft 300, and improve the service life. The connection portions of the reinforcing rods 700 and the rotating shafts 300 are located on the opposite outer sides of the support legs 200 at the corresponding sides.

As shown in FIG. 3B, in order to prevent the position of the reinforcing rods 700 from changing, a top wall of the accommodating cavity 110 is formed with limiting plates 112 extending downwards, the limiting plates 112 are provided in parallel in groups of pairs, and are respectively provided at two sides of the reinforcing rods 700, so as to limit the horizontal displacement of the reinforcing rods 700 and prevent the reinforcing rods 700 from shaking left and right in a horizontal direction and being separated from the rotating shafts 300. At least two groups of limiting plates 112 are provided at corresponding positions of the two reinforcing rods 700, respectively. In order to improve the limiting effect, a plurality of groups of limiting plates may be provided in the length direction of the reinforcing rods 700. In order to improve the limiting effect, the cross section of the reinforcing rods 700 is square, and the plane is attached to the limiting plates 112, so that the attaching effect is better, and the limiting effect is further enhanced. The reinforcing rods 700 are made of hollow square rods, which not only can play a supporting role, but also reduce the weight of the table itself, so that the table is convenient to carry, and the transportation costs are reduced for the factory.
