Detailed implementation manner

[0029] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0030] As Figure 1 shown, an embodiment of the present application discloses a tool table that is easy to fold, including a tabletop body 100 and foldable support legs 200 installed at the bottom of the tabletop body 100. When the tool table is in use, the support legs 200 on both sides of the tabletop body 100 are vertically parallel. Preferably, the support legs 200 on both sides are in an "eight" shape to ensure stable supporting force and can stably support the tabletop body 100. When the tool table is not in use, the support legs 200 on both sides fold towards the center of the bottom of the tabletop body 100 at the same time, which is convenient for the storage of the tool table and reduces its occupied space. The tabletop body 100 is a rectangular plate, and a blind groove is provided on its upper surface for placing sundries. Among them, the blind groove includes a notch for collecting fallen sawdust, a notch for placing hand tools, and a notch for placing accessories. A scale 120 is also provided on the upper surface of the tabletop body 100. The scale 120 can be an integral structure with the tabletop body 100. Preferably, it is engraved on the upper surface of the tabletop body 100, or it can be an existing scale, which is fixed on the surface of the tabletop body 100 by means of bolts, glue or riveting, etc., to facilitate workpiece processing operations. A handle can also be provided on the side surface of the tabletop body 100. After folding, it is convenient to take and place. As Figure 2As shown in the figure, a concave accommodation chamber 110 is formed at the bottom of the tabletop body 100. Two parallelly arranged rotating shafts 300 are fixedly installed in the accommodation chamber 100. One end of the support leg 200 is arranged on the outer periphery of the corresponding rotating shaft 300. The support leg 200 rotates relative to the corresponding rotating shaft 300 to realize the unfolding or folding of the support leg 200. Each rotating shaft 300 is provided with two support legs 200. A connecting plate 800 is riveted and fixed between the two support legs 200. Both ends of the connecting plate 800 are fixedly connected to the corresponding support leg 200 respectively.

[0031] As Figures 3a - 3c shown in the figure, a straight rack 400 is arranged on the outer periphery of the rotating shaft 300. The straight rack 400 extends towards the rotating shaft 300 on the opposite side. In order to reach the position of the rotating shaft 300 on the opposite side, the two straight racks 400 are arranged in parallel and the sawteeth face each other. A gear 500 is arranged between the sawteeth of the two straight racks 400. The outer periphery of the gear 500 meshes with the sawteeth of the straight rack 400. The support leg 200 operates smoothly during the unfolding or folding process, reducing the sense of weightlessness. A vertically downward positioning cylinder 111 with a hollow structure is formed on the top wall of the accommodation chamber 110. The gear 500 is sleeved on the outer periphery of the positioning cylinder 111 and they are coaxial. When the support leg 200 moves, the gear 500 rotates around the outer wall of the positioning cylinder 111. Here, the top wall refers to the normal use state of the tool table.

[0032] In order to avoid the problem of the straight rack 400 and the gear 500 falling off under the action of gravity, a baffle 600 is arranged below the gear 500. The baffle 600 is fixedly connected to the top wall of the accommodation chamber 110 through fixing components such as bolts or screws. A guiding and anti-falling cavity is formed between them. And there is a moving gap between the top surface of the baffle 600 and the gear 500. The guiding and anti-falling cavity not only positions the longitudinal positions of the gear 500 and the straight rack 400 to avoid falling, but also does not interfere with them, ensuring the smooth transmission between them.

[0033] As Figure 5a and Figure 5b shown in the figure, in order to keep the position of the support leg 200 in the folded state fixed, a knob 610 is connected to the bottom surface of the baffle 600. The two support legs 200 are folded towards the middle. The edges of the connecting plates 800 on both sides are respectively located on both sides of the knob 610. Rotate the knob 610 by 90 degrees. The two ends of the knob 610 respectively catch the edges of the corresponding connecting plate 800, realizing the limitation of the position of the support leg 200. When moving the tool table, the support leg 200 will not fall downward due to the action of gravity. In order to make the knob 610 better clamp the connecting plate 800, the edge of the connecting plate 800 close to the knob 610 is thinner than the edge far from the knob 610.

[0034] As Figure 3c and Figure 4As shown, relative reinforcing bars 700 are respectively provided on the two rotating shafts 300. A clamping groove 710 for clamping with the corresponding side rotating shaft 300 is provided at the distal end of the reinforcing bar 700. The opening of the clamping groove 710 faces downward, and a part of the outer peripheral surface of the rotating shaft 300 is embedded in the clamping groove 710, providing a supporting force for the rotating shaft 300, reducing the deformation of the rotating shaft 300, and improving the service life. The connection position of the reinforcing bar 700 and the rotating shaft 300 is located on the relatively outer side of the corresponding side support leg 200.

[0035] As Figure 3b shown, in order to prevent the position of the reinforcing bar 700 from changing, a limiting plate 112 extending downward is formed on the top wall of the accommodating chamber 110. The limiting plates 112 are arranged in parallel in pairs, and are respectively arranged on both sides of the reinforcing bar 700 to limit the horizontal displacement of the reinforcing bar 700, prevent the reinforcing bar 700 from shaking left and right in the horizontal direction, and separating from the rotating shaft 300. There are at least two groups of limiting plates 112, which are respectively arranged at the corresponding positions of the two reinforcing bars 700. In order to improve the limiting effect, multiple groups of limiting plates can be arranged along the length direction of the reinforcing bar 700. In order to improve the limiting effect, the cross section of the reinforcing bar 700 is square, and the plane fits with the limiting plate 112, with a better fitting effect, further strengthening the limiting effect. The reinforcing bar 700 is a hollow square bar, which can not only play a supporting role, but also reduce the self-weight of the tool table, facilitate carrying, and also reduce the transportation cost for the factory.
