[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a folding grid frame includes a mounting plate 1. A bidirectional threaded rod 3 is rotatably connected to the inner side of the mounting plate 1. Moving covers 4 are threadedly connected to both the left and right sides of the outer wall of the bidirectional threaded rod 3. A moving plate 5 is fixedly connected to the top end of the moving cover 4. L-shaped covers 6 are slidably connected to both the front and rear sides of the outer wall of the moving plate 5. A U-shaped block 22 is fixedly connected to the bottom of the L-shaped cover 6. A telescopic plate 23 is rotatably connected to the inner side of the U-shaped block 22. The outer side of the telescopic plate 23 is rotatably connected to the mounting plate 1. A second bevel gear 9 is rotatably connected to the inner bottom of the mounting plate 1. A first bevel gear 7 is fixedly connected to the middle of the outer side of the bidirectional threaded rod 3. The first bevel gear 7 is meshed with the second bevel gear 9. A bottom plate 8 is fixedly connected to the top of the mounting plate 1. A positioning mechanism 2 is arranged on the outer side of the mounting plate 1. The positioning mechanism 2 is used to fix the goods in the device;

[0038] Specifically, by rotating the second bevel gear 9 for meshing drive, the first bevel gear 7 and the threaded column 202 thereon are driven to rotate. The threaded connection mechanism causes the moving plate 5 and the L-shaped cover 6 thereon to move left and right, and at the same time drives the U-shaped block 22 at the bottom to move. The movement of the U-shaped block 22 further drives the telescopic plate 23 to expand and contract and rotate, so that the L-shaped cover 6 slides along the moving plate 5, realizing the folding of the device and effectively reducing its occupied space.

[0039] Referring to Figure 3 , the positioning mechanism 2 includes a third bevel gear 201. The third bevel gear 201 is rotatably connected to the inner top of the mounting plate 1. The third bevel gear 201 is meshed and connected with the first bevel gear 7. A threaded column 202 is fixedly connected to the top of the third bevel gear 201. The top of the threaded column 202 penetrates through the mounting plate 1. A threaded sleeve 203 is threadedly connected to the outer top of the third bevel gear 201. The top end of the threaded sleeve 203 is fixedly connected to a top plate 205. A spring telescopic rod 204 is fixedly connected to the inner top of the L-shaped cover 6. The other ends of the plurality of spring telescopic rods 204 are respectively slidably connected to the bottom periphery of the corresponding top plate 205.

[0040] Specifically, the rotation of the first bevel gear 7 simultaneously drives the third bevel gear 201 and the threaded column 202 thereon to rotate. Through threaded connection, the threaded sleeve 203 and the top plate 205 move up and down. The movement of the top plate 205 can stretch or compress the spring telescopic rod 204. By using the elastic potential energy of the spring and the movement of the threaded sleeve 203, the materials placed in the device are fixed.

[0041] Referring to Figure 1 、 Figure 2 and Figure 3 , the middle of the bottom end of the mounting plate 1 is rotatably connected with a knob 10. The top of the knob 10 penetrates through the mounting plate 1 and is fixedly connected with the second bevel gear 9. A connecting plate 20 is fixedly connected to the outer side of the spring telescopic rod 204. A support 19 is fixedly connected to the outer side of the connecting plate 20. The bottom of the support 19 is fixedly connected with the L-shaped cover 6. A groove 16 is formed in the outer side of the L-shaped cover 6. A fixing plate 15 is slidably connected to the inner side of the groove 16. The middle of the bottom end of the fixing plate 15 is fixedly connected with a mounting cover 21. The mounting cover 21 is slidably connected with the bottom plate 8.

[0042] Specifically, the knob 10 can facilitate the rotation of the second bevel gear 9. Through the support of the connecting plate 20 and the support 19 thereon, the firmness of the fixation between the spring telescopic rod 204 and the L-shaped cover 6 can be improved. By sliding the fixing plate 15 along the groove 16 and at the same time through the mounting cover 21 at its bottom, it can slide along the bottom plate 8, so that when the device expands and contracts, it can still provide shielding for the front and back sides to prevent the materials from falling out of the device.

[0043] Referring to Figure 1 、Figure 2 and Figure 3 On the outer side of the U-shaped block 22, a positioning block 11 is fixedly connected, and a positioning hole 12 is opened on the outer side of the positioning block 11; on the top of the moving plate 5, a positioning plate 13 is fixedly connected, and positioning covers 14 are slidably connected to the front and rear sides of the outer wall of the positioning plate 13. The positioning covers 14 are fixedly connected to the L-shaped cover 6; on the outer side of the positioning cover 14, a handle 17 is fixedly connected, and a sheath 18 is fixedly connected to the outer side of the handle 17;

[0044] Specifically, the device can be supported by the positioning block 11. By installing threaded parts in the positioning hole 12 thereon, the firmness of the device fixation can be improved. With the positioning cover 14 on the positioning plate 13 sliding as the L-shaped cover 6 moves, the left and right sides of the device can be restricted to prevent the material from escaping. At the same time, through the handle 17 and the sheath 18 thereon, it is convenient to install and fix the device.

[0045] Working principle: Before using this device, first rotate the second bevel gear 9 to drive the first bevel gear 7 and the threaded column 202 thereon. Through the meshing transmission and threaded connection mechanism, the moving plate 5 and the L-shaped cover 6 thereon move left and right. At the same time, the U-shaped block 22 at the bottom also moves accordingly, causing the telescopic plate 23 to expand and contract and rotate. This process enables the L-shaped cover 6 to slide along the moving plate 5, effectively realizing the folding of the device and significantly reducing the occupied space;

[0046] The rotation of the first bevel gear 7 simultaneously drives the third bevel gear 201 and the threaded column 202 thereon to rotate. Through the threaded connection, the threaded sleeve 203 and the top plate 205 move up and down. The movement of the top plate 205 can stretch or compress the spring telescopic rod 204. Utilizing the elastic potential energy of the spring and the movement of the threaded sleeve 203, the material inside the fixing device is fixed. These designs optimize the functionality and operation efficiency of the device and are applicable to various usage scenarios and requirements.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
