Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to a clamp with an adjustment structure for easy fixing. Background Art

[0002] A clamp is a tool used for clamping, fastening, or lifting, and is widely used in industries such as metallurgy, transportation, railways, and ports. In the prior art, a Chinese utility model patent with a public document number of CN112340625A discloses a mechanical clamp with an adjustment structure for easy fixation. The utility model solves the problem that when the mechanical clamp clamps and carries objects, the hydraulic press may have a fast lifting speed, causing the objects to vibrate on the mechanical clamp, and then the objects are damaged. In severe cases, the objects fall from the mechanical clamp, causing personal safety to nearby users. The presence of the spring will play a certain shock-absorbing and buffering role on the objects during the handling process;

[0003] However, after the spring has been used for a period of time, the elasticity of the spring may weaken. When the elasticity of the spring weakens, the clamping of the mechanical clamp on the object becomes loose, making the object easy to slip, causing certain safety hazards. Therefore, in response to the weakening of the elastic force of the spring, a clamp with an adjustment structure that is easy to fix is ​​proposed. Utility Model Content

A No. 2 connecting rod 10 is fixedly connected to the connecting frame 2, and both ends of the linkage plate 3 are rotatably connected to the No. 1 connecting rod 9 and the No. 2 connecting rod 10 respectively. The connecting frame 2 is rotatably connected to the movable rivet 7. When the output shaft of the cylinder 1 pushes the pushing seat 8 to move outward, the linkage plate 3 pushes the connecting frame 2 outward, and structures such as the clamping plate 4 and the tension adjustment component 5 are opened to facilitate the loosening of objects. When the output shaft of the cylinder 1 contracts, the pushing seat 8 moves in the opposite direction, so that the linkage plate 3 drives the connecting frame 2 to close, so that the objects are clamped and fixed.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, a tension adjustment component 5 is movably installed on the clamping plate 4, and the tension adjustment component 5 includes a side plate 501, a movable rod 503, a spring 504, a back plate 505 and an adjusting bolt 507. The side plate 501 is movably installed at one side of the clamping plate 4, and the back plate 505 is movably installed at the other side of the clamping plate 4. The two ends of the movable rod 503 are fixedly connected to the side plate 501 and the back plate 505 respectively, and the movable rod 503 is movably installed with the clamping plate 4, and the spring 504 is movably installed on the movable rod 503, and the spring 504 is located between the side plate 501 and the clamping plate 4. The tension adjustment component 5 also includes a rubber pad 502, which is fixedly connected to the side position of the side plate 501. When the splint 4 clamps an object, the rubber pad 502 on the side of the side plate 501 replaces the splint 4 to clamp the object, thereby protecting the surface of the object and avoiding indentations on the object. As the splints 4 approach each other, the side plate 501 and the rubber pad 502 move sideways, and the movable rod 503 moves on the splint 4, so that the spring 504 is compressed. Through the rubber pad 502, the spring 504 and other structures, the object is shock-absorbing and buffered to avoid being crushed.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the adjusting bolt 507 is movably installed on the back plate 505, the tension adjustment component 5 also includes a connecting pipe 506 and a pressing plate 508, the connecting pipe 506 is fixedly connected to the back plate 505, the inner wall of the connecting pipe 506 is engraved with threads, the adjusting bolt 507 is movably installed in the connecting pipe 506, the pressing plate 508 is fixedly connected to one end of the adjusting bolt 507, and the pressing plate 508 is located on the inner side of the back plate 505, the tension adjustment component 5 also includes a positioning seat 509 and a positioning bolt 510, the positioning seat 509 is fixedly connected to the connecting pipe 506, and the pressing plate 508 is fixedly connected to one end of the adjusting bolt 507. On the connecting pipe 506, a screw hole is provided on the positioning seat 509, and a positioning bolt 510 is movably installed in the screw hole of the positioning seat 509. When the spring 504 on the movable rod 503 is compressed, the adjusting bolt 507 is compressed inwardly, so that the distance between the back plate 505 and the clamping plate 4 increases, and the movable rod 503 and the side plate 501 move sideways, thereby compressing the spring 504, so that the elastic force of the spring 504 on the side plate 501 increases, so that when the side plate 501 clamps and fixes objects, the objects are not easy to slip out or fall, thereby reducing safety hazards.

[0025] It should be noted that the utility model is a clamp with an adjustable structure for easy fixation. The output shaft of the cylinder 1 outputs, so that the push seat 8 moves outward, and the push seat 8 opens the connecting frame 2 outward through the linkage plate 3, so that the clamp 4, the side plate 501 and other structures open outward, which is convenient for loosening the object. When the output shaft of the cylinder 1 moves inward, the push seat 8 closes the connecting frame 2 inward through the linkage plate 3, thereby clamping and fixing the object. When the clamp 4 moves toward each other, the rubber pad 502 and the object are clamped to each other, and the side plate 501 moves sideways, so that the movable rod 503 moves sideways on the clamp 4, the spring 504 is compressed by the side plate 501, and the back plate 505 fixedly connected to the movable rod 503 moves sideways, and the adjusting bolt 507, the positioning bolt 510, and the pressure plate 508 thereon move sideways synchronously, and the pressure plate 508 and the clamp 4 are separated from each other through the rubber pad 5 02 and compression spring 504, buffer and shock-absorbing the items to prevent excessive pressure on the splint 4 from causing the items to be crushed. When the elastic force of the spring 504 on the movable rod 503 is weakened, the positioning bolt 510 is screwed outward so that the positioning bolt 510 is moved out from the positioning seat 509, so that the fixing limit of the adjusting bolt 507 is released, and then the adjusting bolt 507 is screwed in the connecting pipe 506 to increase the distance between the back plate 505 and the splint 4, so that the movable rod 503 and the side plate 501 move sideways, so that the spring 504 is compressed, and the elastic force of the spring 504 on the side plate 501 is increased. When the adjusting bolt 507 is adjusted to a suitable position, the positioning bolt 510 is screwed inward in the screw hole of the positioning seat 509, so that the positioning bolt 510 fixes the adjusting bolt 507, so that when the splint 4 clamps the items again, the items are not easy to slide out or fall off.
