[0002] Clamps are a type of connection device used to connect grooved pipes, valves, and pipe fittings. They are used as fasteners to connect pipes. Knob clamps are widely used in liquid dispensing equipment because they are labor-saving to rotate and lock, easy to grasp, and have strong fastening properties. Figure 1 As shown, the knob clamp includes a first semicircular ring 10, a second semicircular ring 20 and a locking assembly, and the locking assembly includes a stud 31 and a flat knob 32. One end of the first semicircular ring 10 and the second semicircular ring 20 are rotatably connected, and the other ends of the first semicircular ring 10 and the second semicircular ring 20 are respectively provided with a first corner 11 and a second corner 21. When the first semicircular ring 10 and the second semicircular ring 20 are closed and tightly embrace the pipe, the first corner 11 and the second corner 21 overlap, the stud 31 passes through the first corner 11 and the second corner 21, and the flat knob 32 is threadedly connected to the stud 31 and abuts against the surface of the first corner 11 facing away from the second corner 21 to lock the first corner 11 and the second corner 21, thereby locking the first semicircular ring 10 and the second semicircular ring 20.

[0003] However, in practical applications of the knob clamp, the modularly designed equipment has a problem of insufficient installation space. Due to the small space, the operator's hands cannot reach in to pinch the two flat side walls of the flat knob 32 to tighten or loosen the knob.

[0004] Therefore, it is urgent to propose a clamp disassembly and assembly device to solve the above problems. Utility Model Content

[0033] The clamp disassembly and assembly device provided in this embodiment saves effort and improves work efficiency when disassembling the flat knob 32 ; it can avoid damage to the flat knob 32 during disassembly and assembly; and its compact structure solves the problem that the operator's hands cannot reach into a narrow space to tighten or loosen the flat knob 32 .

[0034] Specifically, such as Figure 2 and Figure 3As shown, the clamp assembly and disassembly device is used to disassemble and assemble the flat knob 32 of the knob clamp, and includes a buckle cover assembly 100 and a wrench assembly 200. The buckle cover assembly 100 is provided with a receiving cavity. When the buckle cover assembly 100 is buckled onto the outside of the flat knob 32, the flat sidewalls on both sides of the flat knob 32 abut against the inner sidewalls of the receiving cavity. One end of the wrench assembly 200 is fixedly connected to the buckle cover assembly 100. By rotating the other end of the wrench assembly 200, the wrench assembly 200 can drive the buckle cover assembly 100 to rotate and tighten the flat knob 32.

[0035] Based on the above design, the flat side walls on both sides of the flat knob 32 can abut against the inner side walls of the accommodating cavity, so that the buckle cover assembly 100 can tightly cover the flat knob 32. One end of the wrench assembly 200 is fixedly connected to the buckle cover assembly 100. By rotating the other end of the wrench assembly 200, the wrench assembly 200 can drive the buckle cover assembly 100 to rotate to screw the flat knob 32. By rotating the wrench assembly 200 and the buckle cover assembly 100 to screw the flat knob 32, on the one hand, the wrench assembly 200 can increase the rotational torque, making the tightening or loosening operation of the flat knob 32 more labor-saving, and improving the efficiency of the assembly and disassembly of the flat knob 32. On the other hand, the buckle cover assembly 100 abuts and clamps against the flat side walls of the flat knob 32, increasing the contact area between the buckle cover assembly 100 and the flat knob 32, and preventing the flat knob 32 from being damaged due to uneven force. On the other hand, the buckle cover assembly 100 covers the flat side wall of the flat knob 32, and has a simple and compact structure; and the flat assembly is indirectly screwed through the wrench assembly 200, which solves the problem that the operator's hand cannot reach into a narrow space to tighten or loosen the flat knob 32.

[0036] Furthermore, the wrench assembly 200 is detachably connected to the top of the cover of the buckle cover assembly 100. The wrench assembly 200 is detachably connected to the buckle cover assembly 100, which facilitates the disassembly, placement and storage of the clamp disassembly and assembly device; the wrench assembly 200 is connected to the top of the cover of the buckle cover assembly 100, saving space when the clamp disassembly and assembly device is operated.

[0037] There are many specific structural styles of the buckle cover assembly 100. In this embodiment, Figure 4 As shown, the buckle cover assembly 100 includes a cover plate 120 and two clamping plates 110. The two clamping plates 110 are arranged relative to each other along a first direction (x direction in the figure). The cover plate 120 is located between the two clamping plates 110 and connects the two clamping plates 110. The wrench assembly 200 is connected to the cover plate 120. The clamping plates 110 and the cover plate 120 have a simple structure and low cost.

[0038] The two clamping plates 110 are parallel to each other, and the cover plate 120 is arranged perpendicular to the two clamping plates 110, so that the buckle cover assembly 100 has a symmetrical structure, thereby ensuring uniform clamping force on the flat knob 32.

[0039] Further, continue as Figure 2 and Figure 3 As shown, the wrench assembly 200 is connected to the center point of the cover plate 120 , further improving the force uniformity of the flat knob 32 .

[0040] like Figure 4 and Figure 5 As shown, the wrench assembly 200 includes a handle 210 and a chuck 220. The handle 210 is parallel to the plane of the cover plate 120. One end of the chuck 220 is perpendicularly connected to the handle 210, and the other end of the chuck 220 is perpendicularly connected to the cover plate 120. The handle 210 is parallel to the plane of the cover plate 120 and the handle 210 and the cover plate 120 are connected by the chuck 220. This connection is simple and increases the rotational moment, thereby increasing the torque.

[0041] Optionally, a polygon is provided at the center of the cover plate 120 , and the shape of the clamping head 220 is adapted to the shape of the polygon, and the clamping head 220 can be movably inserted into the polygon.

[0042] In this embodiment, the polygonal hole 101 is a hexagonal hole.

[0043] Continue as Figure 2 As shown, the clamp disassembly and assembly device also includes a limit assembly, which is located at both ends of the two clamps 110 along the second direction. When the buckle cover assembly 100 is buckled on the flat knob 32, the limit assembly can limit the displacement of the flat knob 32 along the second direction, thereby preventing the clamp disassembly and assembly device from sliding out when the flat knob 32 is screwed.

[0044] It should be noted that the second direction (y direction in the figure) is perpendicular to the first direction. When the buckle cover assembly 100 is buckled onto the flat knob 32, the first direction is the thickness direction of the flat knob 32, and the second direction is the width direction of the flat knob 32.

[0045] Furthermore, the limiting assembly includes two groups of limiting posts 310, which are respectively located at both ends of the clamping plate 110 along the second direction, and the ends of the limiting posts 310 pass through and connect the two clamping plates 110. The limiting posts 310 are simple in structure, simple in setting and low in cost.

[0046] Furthermore, each group of limiting posts 310 has a plurality of limiting posts 310, and the limiting posts 310 in the same group of limiting posts 310 are spaced apart along a third direction, which is perpendicular to both the first direction and the second direction.

[0047] The third direction is the z direction in the figure.

[0048] In this embodiment, the number of each group of limiting posts 310 is two.

[0049] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
