DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In an embodiment of the utility model, a steel mesh conversion frame includes a conversion frame body 100, U-shaped clamps 200 are arranged on both sides of the conversion frame body 100, and the U-shaped openings of the two U-shaped clamps 200 are opposite to each other. Cylinders 210 are fixedly arranged on both sides of the conversion frame body 100, and the piston rod ends of the cylinders 210 are fixedly connected to the U-shaped clamps 200. When the two cylinders 210 are started, their piston rods push the two U-shaped clamps 200 to move toward each other to fix and clamp the steel mesh located in the middle cavity of the conversion frame body 100. The two ends of the U-shaped clamp 200 are located inside the conversion frame body 100, so that the movement of the U-shaped clamp 200 is smoother.

[0021] See also Figure 1-4 A plurality of lifting plates 400 are provided inside the U-shaped groove of the U-shaped splint 200, and a plurality of first threaded rods 310 parallel to the lifting plates 400 are provided inside the U-shaped groove of the U-shaped splint 200. A first bevel gear 320 is sleeved on the outer surface of the first threaded rod 310. A nut sleeve 330 is fixed to the connecting portion between the first bevel gear 320 and the first threaded rod 310. The outer surface of the first threaded rod 310 is threadedly connected with the nut sleeve 330. The outer surface of the first bevel gear 320 is meshedly connected with the second bevel gear 340. A second threaded rod 350 is embedded in the middle of the second bevel gear 340. The outer surface of the second threaded rod 350 is threadedly connected with the lifting plate 400. When the U-shaped splint 200 contacts the steel mesh Before, the first threaded rod 310 will first contact the steel mesh. As the U-shaped clamp 200 continues to squeeze the steel mesh, the steel mesh pushes the first threaded rod 310 to move, so that a threaded force is generated between the first threaded rod 310 and the nut sleeve 330 to drive the nut sleeve 330 to rotate, that is, the first bevel gear 320 is rotated, and the meshing force between the first bevel gear 320 and 34 is driven to rotate the second bevel gear 340, and then the second threaded rod 350 is rotated and a threaded force is generated between the lifting plate 400 to drive the lifting plate 400 to move toward the steel mesh. In the process of the U-shaped clamp 200 clamping the steel mesh horizontally, the lifting plate 400 descends to clamp the steel mesh vertically, and the operation is simple.

[0022] See also Figure 3One end of the first threaded rod 310 extends to the inside of the U-shaped clamp 200 and is fixedly connected to a guide block 510. A plurality of fixed blocks 520 corresponding to the positions of the guide blocks 510 are fixedly arranged on one side of the U-shaped clamp 200. Guide grooves 530 that fit with the guide blocks 510 are provided inside the U-shaped clamp 200 and the fixed blocks 520, and the two guide grooves 530 are connected. During the movement of the first threaded rod 310, the guide block 510 moves along the guide groove 530 to guide the movement of the first threaded rod 310, thereby preventing the first threaded rod 310 from rotating and affecting the stable rotation of the first bevel gear 320.

[0023] See also Figure 1-5 Through slots 540 that fit with the fixing blocks 520 are provided on both sides of the conversion frame body 100. The setting of the through slots 540 enables the fixing blocks 520 to pass through the conversion frame body 100 through the through slots 540 during the movement of the U-shaped clamp 200, thereby preventing the fixing blocks 520 from interfering with the movement of the U-shaped clamp 200.

[0024] See also Figure 3 The outer surface of one end of the second threaded rod 350 close to the second bevel gear 340 is rotatably connected to a fixed plate 610, and the other end of the second threaded rod 350 is rotatably connected to the U-shaped clamping plate 200. The outer arc surface of the fixed plate 610 is fixedly connected to two support plates 620, and the fixed plate 610 is used to support the rotation of the second threaded rod 350.

[0025] The working principle and use process of the utility model are as follows: when in use, the steel mesh is placed in the cavity position in the middle of the conversion frame body 100, and the two cylinders 210 are started so that their piston rods push the two U-shaped clamping plates 200 to move towards each other to fix and clamp the steel mesh located in the cavity position in the middle of the conversion frame body 100. Before the U-shaped clamping plates 200 contact the steel mesh, the first threaded rod 310 will first contact the steel mesh. As the U-shaped clamping plates 200 continue to squeeze the steel mesh, the steel mesh pushes the first threaded rod 310 to move, so that a thread force is generated between the first threaded rod 310 and the nut sleeve 330 to drive the nut sleeve 330 to rotate, thereby realizing the first During the rotation of the bevel gear 320, the guide block 510 moves along the guide groove 530 to guide the movement of the first threaded rod 310 to prevent the rotation of the first threaded rod 310 from affecting the stable rotation of the first bevel gear 320. The first bevel gear 320 rotates and generates a meshing force with 34 to drive the second bevel gear 340 to rotate. Then, the second threaded rod 350 rotates and generates a thread force with the lifting plate 400 to drive the lifting plate 400 to move toward the steel mesh. In the process of the U-shaped clamping plate 200 clamping the steel mesh horizontally, the lifting plate 400 descends to clamp the steel mesh vertically, which is simple to operate.

[0026] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
