[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a load-bearing and stable plastic folding table, comprising:

[0030] A plastic tabletop 100, with a rectangular plastic enclosure 200 fixed to its lower surface;

[0031] Support legs 300 are used to support the plastic tabletop 100, and there are four support legs 300.

[0032] The drive assembly 400 is used to drive the four support legs 300 to automatically unfold. The drive assembly 400 includes two rectangular frames 401 symmetrically fixed to the lower surface of the plastic tabletop 100, and two symmetrical sliders 402 slidably disposed on the inner wall of the rectangular frames 401. The top of the support leg 300 is rotatably connected to the inner wall of the rectangular plastic enclosure 200. The surface of the slider 402 is rotatably provided with a top rod 403, and the other end of the top rod 403 is rotatably connected to the surface of the support leg 300. The drive assembly 400 also includes a rotating block 404 rotatably disposed on the surface of the plastic tabletop 100 for driving the four sliders 402 to move simultaneously.

[0033] See Figure 3 The inner wall of the rectangular frame 401 is rotatably provided with a bidirectional lead screw 405, and the surfaces of the two sliders 402 are provided with threaded holes that are threaded to the outer surface of the bidirectional lead screw 405.

[0034] Specifically, by setting a bidirectional lead screw 405, the rotation of the bidirectional lead screw 405 can drive the two sliders 402 to move simultaneously towards the middle or to both sides.

[0035] See Figure 3 A connecting shaft 406 is rotatably provided on the opposite surfaces of the two rectangular frames 401. The two ends of the connecting shaft 406 extend into the interior of the two rectangular frames 401 respectively. The ends of the connecting shaft 406 and the surface of the bidirectional lead screw 405 are both fixed with a first bevel gear 407 that meshes with each other.

[0036] Specifically, by setting the first bevel gear 407, the bidirectional lead screw 405 can be automatically rotated by the rotation of the connecting shaft 406.

[0037] See Figure 2 The inner wall of the rectangular plastic fence 200 is rotatably provided with a rotating shaft 408 extending to the outer surface of the rectangular plastic fence 200. A rotating block 404 is fixed at one end of the rotating shaft 408, and the other end of the rotating shaft 408 and the surface of the connecting shaft 406 are both fixed with a second bevel gear 409 that meshes with each other.

[0038] Specifically, by setting the second bevel gear 409, the connecting shaft 406 can be automatically rotated by the rotation of the rotating shaft 408.

[0039] See Figure 4 The inner wall of the rectangular plastic enclosure 200 is fixedly provided with a first rotating frame 4010, and the inner wall of the first rotating frame 4010 is rotatably provided with a first rotating rod 4011. The top of the support leg 300 is provided with a first mounting hole that is fixedly connected to the surface of the first rotating rod 4011.

[0040] Specifically, by setting the first rotating frame 4010, the top of the support leg 300 can be rotatably connected to the inner wall of the rectangular plastic enclosure 200.

[0041] See Figure 3 and Figure 4 The surface of the slider 402 is provided with a rotating groove, and the inner wall of the rotating groove is rotatably provided with a second rotating rod 4012. The surface of the support leg 300 is fixedly provided with a second rotating frame 4013, and the inner wall of the second rotating frame 4013 is rotatably provided with a third rotating rod 4014. One end of the top rod 403 is provided with a second mounting hole that is fixedly connected to the surface of the second rotating rod 4012, and the other end of the top rod 403 is provided with a third mounting hole that is fixedly connected to the surface of the third rotating rod 4014.

[0042] Specifically, by setting the second rotating frame 4013 and the second rotating rod 4012, one end of the top rod 403 can be rotatably connected to the surface of the slider 402, and the other end of the top rod 403 can be rotatably connected to the surface of the support leg 300.

[0043] In this invention, by setting up a drive assembly 400, the folding table can rotate during actual use by rotating the rotating block 404 to drive the rotating shaft 408 to rotate. The rotation of the rotating shaft 408 drives the connecting shaft 406 to rotate under the action of two second bevel gears 409. The rotation of the connecting shaft 406 drives the bidirectional lead screw 405 to rotate under the action of two first bevel gears 407. This causes the two bidirectional lead screws 405 to rotate simultaneously. The rotation of the bidirectional lead screws 405 causes the two sliders 402 to move towards the center simultaneously, thereby causing the top rod 403 to push the support leg 300, causing the support leg 300 to rotate around the first rotating frame 4010. This allows all four support legs 300 to unfold simultaneously, achieving the purpose of quick and convenient unfolding and use of the folding table. Moreover, the four support legs 300 are highly stable after unfolding, preventing the support legs 300 from automatically rotating under external force, thus effectively ensuring the stability of the plastic folding table.

[0044] See Figure 3 An adjustment component 500 is provided at the end of the support leg 300. The adjustment component 500 includes a cylindrical cavity opened at the end of the support leg 300 and a telescopic column 501 slidably disposed on the inner wall of the cylindrical cavity. An anti-slip pad 502 is fixed at the bottom end of the telescopic column 501, and a limiting block 503 is fixed at the end of the telescopic column 501. A strip-shaped opening 504 for the limiting block 503 to slide is opened on the outer surface of the support leg 300. A cylindrical threaded hole is also opened on the surface of the support leg 300, and a threaded set screw 505 is threadedly connected to the inner wall of the cylindrical threaded hole.

[0045] In this invention, by setting an adjustment component 500, after the four support legs 300 are unfolded, the position of the telescopic column 501 can be fixed according to the actual situation through the threaded set screw 505, thereby realizing the adjustment of the length of the support legs 300 of the plastic folding table and improving the practicality of the plastic folding table.

[0046] Working principle: In actual use, the folding table rotates by rotating block 404, which drives shaft 408 to rotate. The rotation of shaft 408, under the action of two second bevel gears 409, drives connecting shaft 406 to rotate. The rotation of connecting shaft 406, under the action of two first bevel gears 407, drives double-acting screw 405 to rotate, thus causing both double-acting screws 405 to rotate simultaneously. The rotation of double-acting screws 405 causes two sliders 402 to move simultaneously towards the center, thereby causing push rod 403 to push against support leg 300, causing support leg 300 to rotate around the first rotating frame 4. The 010 is rotated, allowing the four support legs 300 to unfold simultaneously, achieving the purpose of quick and convenient unfolding and use of the folding table. Moreover, the four support legs 300 are highly stable after unfolding, preventing them from automatically rotating under external force, thus effectively ensuring the stability of the plastic folding table. Furthermore, after the four support legs 300 are unfolded, the position of the telescopic column 501 can be fixed according to the actual situation through the threaded set screw 505, realizing the adjustment of the length of the support legs 300 of the plastic folding table and improving the practicality of the plastic folding table.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
