[0027] Before describing the embodiments of this utility model in detail, the application environment of this utility model will be described first. The technology of this utility model is mainly applied in the field of clamping technology. This utility model is used to solve the problem that existing sheet clamps are prone to causing material surface damage or damage to the structural integrity of products due to excessive clamping force.

[0028] Please combine Figures 1 to 4 As shown, this utility model provides a sheet clamp.

[0029] In an exemplary embodiment of this application, the sheet clamp includes: a clamping assembly 1, including a fixed part 101 and a movable part 102, wherein the movable part 102 is used to cooperate with the fixed part 101 to clamp the sheet;

[0030] The connecting component 2 and the fixing component 101 are disposed at one end of the connecting component 2 along the axial direction. The movable component 102 can move along the axial direction of the connecting component 2 to approach or move away from the fixing component 101, so that the clamping assembly 1 clamps or releases the sheet.

[0031] Adjusting component 3 is disposed on connecting component 2. Adjusting component 3 can move along the axial direction of connecting component 2 to adjust the travel of movable component 102 along the axial direction of connecting component 2.

[0032] The operating component 4 includes an operating part 401 and a pressing part 402. The pressing part 402 is rotatably connected to the adjusting component 3. The operating part 401 is used to drive the pressing part 402 to rotate, so that the movable component 102 is close to the fixed component 101 to clamp the sheet.

[0033] In this embodiment, both the fixed component 101 and the movable component 102 are rectangular plate structures. The rectangular plate structure of the fixed component 101 and the movable component 102 can effectively increase the contact area between the clamping assembly 1 and the clamped part (sheet), thereby making the clamping force more uniform and effectively preventing the clamped part from falling off the clamp. Both the fixed component 101 and the movable component 102 are made of non-metallic materials, including but not limited to polytetrafluoroethylene (PTFE), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) or ceramic materials, which have high chemical stability and corrosion resistance. When the clamp is used in harsh working conditions, it can effectively extend the service life of the clamp. In this embodiment, the movable part 102 and the fixed part 101 cooperate to clamp and fix the sheet, avoiding damage to the integrity of the sheet product. The movable part 102 on the connecting part 2 is adjusted by the adjusting part 3 to adjust the distance between the movable part 102 and the fixed part 101. Since the pressing part 402 is rotatably mounted on the adjusting part 3, the pressing part 402 drives the movable part 102 to move along the axial direction of the connecting part 2 and fix the stroke. Therefore, by adjusting the distance between the movable part 102 and the fixed part 101, the clamping force of the clamping assembly 1 can be adjusted, thereby effectively avoiding the problem of material surface damage caused by excessive clamping force or sheet falling off the fixture due to insufficient clamping force.

[0034] In an exemplary embodiment of this application, the connecting component 2 is a lead screw, and the fixing component 101 has a threaded blind hole 101a, and the fixing component 101 is threadedly connected to the lead screw.

[0035] In this embodiment, the fixing component 101 is fixedly connected to the lead screw by a threaded connection. The threaded connection provides a high-strength connection, ensuring a tight fit between the fixing component 101 and the lead screw. The fixing component 101 can be connected or disassembled by rotating the lead screw, which is simple and quick to operate. The design of the threaded blind hole 101a allows the connection between the connecting component 2 and the fixing component 101 to be completely hidden inside the fixing component 101, saving space and making the connection more aesthetically pleasing. It also reduces the space occupied by the connecting component 2 and increases the compactness and stability of the structure.

[0036] In an exemplary embodiment of this application, a through hole 102a is provided on the movable component 102 corresponding to the threaded blind hole 101a, and the through hole 102a is clearance-fitted with the lead screw.

[0037] In this embodiment, by opening a through hole 102a on the movable component 102, the diameter of the through hole 102a is larger than the diameter of the connecting component 2, so that the movable component 102 can move relative to the connecting component 2 along the axial direction of the connecting component 2, while the connecting component 2 can limit the movable component 102 along its radial direction.

[0038] In an exemplary embodiment of this application, the fixed component 101 is provided with an elastic reset member, which abuts against the movable component 102. The elastic reset member is used to provide an elastic reset force to the movable component 102 along the axial direction of the connecting component 2.

[0039] In this embodiment, by providing an elastic reset member between the fixed member 101 and the connecting member 2, when the operating part 401 drives the pressing part 402 to eliminate the pressing force on the movable member 102, the movable member 102 can be reset under the elastic reset force of the elastic reset member, maintaining the gap between the movable member 102 and the fixed member 101, which facilitates the installation of the clamped part next time, so that the movable member 102 does not need to be manually lifted, thus providing installation space for the clamped part.

[0040] In an exemplary embodiment of this application, the adjusting component 3 is a hexagonal nut, and the adjusting component 3 is threadedly connected to the connecting component 2.

[0041] In this embodiment, a fixed component 101, a movable component 102, and an adjusting component 3 are sequentially connected along the axial direction of the connecting component 2. The adjusting component 3 is threadedly connected to the connecting component 2 using a hexagonal nut. The adjusting component 3 can also limit the movable component 102 along the axial direction of the connecting component 2. By rotating the adjusting component 3 to move along the axial direction of the connecting component 2, the travel distance of the movable component 102 along the axial direction of the connecting component 2 can be adjusted, thereby adjusting the distance between the movable component 102 and the fixed component 101. Since the clamping part 402 is provided on the adjusting component 3, the clamping part 402 can drive the movable component 102 to move along the axial direction of the connecting component 2 with a fixed travel distance. Therefore, by adjusting the distance between the movable component 102 and the fixed component 101, the clamping force of the clamping assembly 1 can be adjusted, thereby effectively avoiding the problem of material surface damage caused by excessive clamping force or the problem of the sheet falling off the fixture due to insufficient clamping force.

[0042] In an exemplary embodiment of this application, the adjusting component 3 is provided with a rotating shaft 301, and the pressing part 402 is rotatably connected to the rotating shaft 301.

[0043] In this embodiment, the rotating shaft 301 is disposed on the side surface of the adjusting component 3, and the pressing part 402 is provided with a shaft hole, and the pressing part 402 is clearance-fitted with the rotating shaft 301.

[0044] In one exemplary embodiment of this application, the clamping part 402 is an eccentric wheel.

[0045] In this embodiment, by setting the clamping part 402 as an eccentric wheel, when the operating part 401 drives the clamping part 402 to rotate along the vertical plane, the clamping part 402 can apply a clamping force to the movable part 102 along the axial direction of the connecting part 2 or remove the clamping force, thereby clamping the sheet or releasing the sheet by the clamping assembly 1.

[0046] In an exemplary embodiment of this application, the operating part 401 has a "U"-shaped connector 401a, and a clamping part 402 is symmetrically provided at the "U"-shaped connector 401a.

[0047] In this embodiment, by symmetrically arranging pressing parts 402 on the "U"-shaped connector 401a, and by having the pressing parts 402 abut against the side wall of the adjusting component 3, the contact area between the pressing parts 402 and the adjusting component 3 is increased. By driving the operating component 4 to rotate along the horizontal plane, the adjusting component 3 can be moved along the axial direction of the connecting component 2, thereby adjusting the travel of the movable component 102.

[0048] In an exemplary embodiment of this application, the control part 401 is provided with an anti-slip sleeve 401b.

[0049] In this embodiment, by providing an anti-slip sleeve 401b on the control part 401, the operator can effectively avoid slipping or losing control when driving the control component 4.

[0050] In another exemplary embodiment, the surface of the fixed member 101 opposite to the movable member 102 is provided with an anti-slip pad, which can increase the friction between the clamping assembly 1 and the clamped part, and further prevent the clamped part from falling off the clamp.

[0051] The working principle is as follows: the movable part 102 cooperates with the fixed part 101 to clamp and fix the sheet, avoiding damage to the integrity of the sheet product; the movable part 102 on the connecting part 2 is adjusted by the adjusting part 3 to adjust the distance between the movable part 102 and the fixed part 101. Since the clamping part 402 is rotatably mounted on the adjusting part 3, the clamping part 402 drives the movable part 102 to move along the axial direction of the connecting part 2 and fix the stroke. Therefore, by adjusting the distance between the movable part 102 and the fixed part 101, the clamping force of the clamping assembly 1 can be adjusted, thereby effectively avoiding the problem of material surface damage caused by excessive clamping force or sheet falling off the fixture due to insufficient clamping force.

[0052] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
