Moreover, according to the shape and size of the plate to be clamped 1, different types and numbers of clamps are set, which can also improve the clamping stability of the plate.

[0034] As shown in the drawings, Figure 3As shown, in the embodiment, the support base 2 of the straight-line clamp 8 comprises a top plate 801, a bottom plate 802 and a side plate 803; the top plate 801 and the bottom plate 802 are oppositely arranged on one side of the side plate 803, the upper surface of the bottom plate 802 is a support surface, and the support surface 4 of the bottom plate 802 cooperates with the pressing surface of the movable clamp plate 3 to form a clamping space 5 for clamping the side edge of the plate.

Specifically, the support surface 4 of the bottom plate 802 and the pressing surface of the movable clamp plate 3 can be covered with a gasket 15 made of soft material (such as rubber gasket, etc.), which prevents the plate from being damaged during clamping.

[0035] As shown in Figure 3 and Figure 4 As shown, in the embodiment, the support base 2 of the straight-line clamp 8 comprises a top plate 801, a bottom plate 802 and a side plate 803; the top plate 801 and the bottom plate 802 are oppositely arranged on one side of the side plate 803, the upper surface of the bottom plate 802 is a support surface, and the support surface 4 of the bottom plate 802 cooperates with the pressing surface of the movable clamp plate 3 to form a clamping space 5 for clamping the side edge of the plate.

Through the sliding cooperation between the sliding groove and the sliding groove 14, the movable clamp plate 3 is moved relative to the support base 2 in a direction perpendicular to the support surface 4, the clamping space of the straight-line clamp 8 matches the side edge of the plate, and the side edge of the plate is clamped or loosened by the lifting of the movable clamp plate 3. Specifically, the support surface 4 of the bottom plate 802 and the pressing surface of the movable clamp plate 3 can be covered with a gasket 15 made of soft material (such as rubber gasket, etc.), which prevents the plate from being damaged during clamping.

[0036] In the embodiment, in order to realize the transmission connection between the operating rod 6 and the clamp, the top of the straight-line clamp 8 and the corner clamp 9 is further provided with a bracket 10, the bracket 10 is fixed on the top plate 801 of the straight-line clamp 8 or the first sector plate 901 of the corner clamp 9, the bracket 10 is provided with a mounting hole, and the operating rod 6 is rotatably arranged in the mounting hole.

[0037] To ensure that the device has a certain self-locking effect, a locking member (not shown in the figure) can also be provided. The mounting hole is provided with a threaded hole distributed along its radial direction. The locking member is screwed into the threaded hole to lock the operating lever. By locking the operating lever with the locking member, displacement of the movable clamping plate when clamping the plate is prevented, and the overall device is improved in terms of anti-loosening. In actual use, the locking member can be selected as a screw,

[0038] In this embodiment, the operating lever assembly includes a plurality of operating levers 6, each of which is distributed along the side edge of the plate to be clamped 1, and at least two adjacent operating levers 6 are drivingly connected. In this embodiment, at least two operating levers 6 are drivingly connected, and driving one of the operating levers 6 with the driving assembly can realize synchronous rotation of the drivingly connected operating levers 6, thereby realizing synchronous opening and closing of the clamps drivingly connected to the operating levers 6 around the plate. In actual implementation, the driving connection between the operating levers is divided into different cases: for example, all operating levers 6 distributed around the plate to be clamped are drivingly connected, and driving rotation of one of the operating levers with one driving assembly can realize synchronous opening and closing of all clamps around the plate. This setting can reduce the number of driving assemblies and save costs. Alternatively, two adjacent operating levers can be drivingly connected, and each pair of drivingly connected operating levers can be driven by the same driving assembly to realize synchronous opening and closing of the clamps on the two operating levers. This setting can reduce the load on the driving assembly and ensure the accuracy of the opening and closing of the clamps. Of course, three adjacent operating levers can also be drivingly connected. In specific implementation, the number of drivingly connected operating levers is not limited, and the number can be selected according to the site conditions.

[0039] In this embodiment, the lifting assembly includes a lead screw (not shown in the figure), the axis of the lead screw is distributed along the vertical direction, and the lead screw is rotatably arranged in the clamping space along its own axis. The top end of the lead screw passes through the top of the clamp (the top plate 801 or the first sector plate 901) and is provided with a first bevel gear 11. The movable clamping plate 3 is connected with the lead screw nut of the lead screw. The operating lever 6 is provided with a second bevel gear 12 for driving connection with the first bevel gear 11 of the lead screw. One end or both ends of the operating lever 6 are provided with a third bevel gear 13 for driving connection with the adjacent operating lever 6. Reference Figures 2-4A second bevel gear 12 is mounted on the operating lever 6, and a first bevel gear 11 is mounted on the top of the linear clamp 8 and the corner clamp 9. The first bevel gear 11 is connected to the lead screw, and its rotation drives the lead screw to rotate around its own axis, causing the moving clamp 3 to rise and fall along the lead screw. Depending on the actual transmission situation, a third bevel gear 13 may be mounted on one or both ends of the operating lever 6 (the size of the third bevel gear 13 is smaller than that of the second bevel gear 12, facilitating the layout and transmission of bevel gears at corners). By setting up a bevel gear transmission group, rotating one operating lever can rotate all the operating levers it drives, and simultaneously, the lead screw connected to the operating lever also rotates synchronously, achieving synchronous opening and closing of multiple clamps.

[0040] The drive assembly 7 includes a drive motor or a handle for rotating the operating lever. Driving the operating lever with a drive motor saves time and effort. In scenarios where an external power source is inconvenient, the operating lever can be rotated using the handle on the lever.

[0041] In practice:

[0042] like Figure 1 As shown, the plate to be clamped 1 is quadrilateral. Straight clamps 8 are distributed along the sides of the plate to be clamped 1, and corner clamps 9 are located at the four corners of the plate to be clamped 1. Operating levers 6 are distributed along the four side plates of the plate to be clamped 1. The operating levers 6 are connected to the corresponding clamps via a transmission mechanism. One end of one operating lever 6 is equipped with a third bevel gear 13 for transmission connection with the adjacent operating lever 6, and the other end is equipped with a handle for rotating the operating lever 6. The other three operating levers 6 are connected to each other via the third bevel gear 13. During operation, rotating the handle of the operating lever 6 causes the four operating levers 6 to rotate synchronously. Simultaneously, the moving clamping plates 3 of each clamp connected to the operating lever 6 also rise and fall synchronously, thus achieving synchronous opening and closing of the clamps. By implementing this device, it is no longer necessary to open and close each clamp individually. The operation process is simple, and it can be modularly designed according to the shape of the plate. The overall device has a high total locking force, is stable, and safe.

[0043] Example 2:

[0044] This embodiment is the same as embodiment 1 except for the following technical solutions:

[0045] In this embodiment, the angle of the plate 1 to be clamped is 90°, and the corner clamp is made of two straight clamps spliced ​​together according to the angle of the plate to be clamped. This setting can improve the utilization rate of the straight clamps, eliminating the need to manufacture a separate corner clamp, thus saving costs for enterprises.
