[0024] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0025] As mentioned in the background art, during the disassembly and assembly of pipe fittings joints in the prior art, most of them use manual screwing or wrench screwing, and the clamping force on the pipe fittings joints is insufficient. It is easy to occur that the pipe fittings joints cannot be screwed to the bottom of the thread, and the torque requirement cannot be met, resulting in problems such as loosening and leakage failures. In view of the above technical problems, the present application provides a clamping mechanism for clamping pipe fittings joints. The clamping mechanism includes a clamping component 100 and a force application part 200. The pipe fittings joints are clamped by the first clamping body 110 and the second clamping body 120. After clamping, the force application component is engaged into the engaging space 210, and the pipe fittings joints are driven to rotate by the clamping component 100, so as to improve the control accuracy of the installation torque and facilitate the disassembly and assembly of the pipe fittings joints.

[0026] Please refer to Figures 1 to 5 , the present invention provides a clamping mechanism, including: a clamping component 100, the clamping component 100 includes a first clamping body 110 and a second clamping body 120 which are connected to each other. A clamping space 130 is provided between the first clamping body 110 and the second clamping body 120. The second clamping body 120 is movably arranged relative to the first clamping body 110 to clamp a target workpiece in the clamping space 130 or release it from the clamping space 130; a force application part 200, arranged on the first clamping body 110, the force application part 200 has an engaging space 210, and by engaging with a target force application component through the engaging space 210, the target force application component applies a force to the clamping component 100.

[0027] According to the clamping mechanism provided by the present application, it includes a clamping component 100 and a force application part 200. The clamping component 100 includes a first clamping body 110 and a second clamping body 120 which are connected to each other. A clamping space 130 is provided between the first clamping body 110 and the second clamping body 120. The second clamping body 120 is movably arranged relative to the first clamping body 110 to clamp the target workpiece in the clamping space 130 or release it from the clamping space 130. The force application part 200 is arranged on the first clamping body 110. The force application part 200 has a clamping space 210, and is clamped with the target force application component through the clamping space 210, so that the target force application component applies a force to the clamping component 100. Such a setting can clamp the target workpiece through the first clamping body 110 and the second clamping body 120. After the clamping is completed, the target force application component is clamped into the clamping space 210, and the clamping component 100 is driven to rotate by rotating the target force application component, so as to screw the target workpiece to a predetermined position. In this way, the clamping force on the target workpiece can be ensured, and the control accuracy of the installation torque of the target workpiece can be improved by using the force application part 200, which is convenient for the disassembly and assembly of the target workpiece.

[0028] Specifically, as Figure 1 and Figure 2 shown, the force application part 200 includes: a mating sleeve 220, which is arranged on the first clamping body 110. The mating sleeve 220 protrudes from the surface of the first clamping body 110. At least part of the barrel cavity of the mating sleeve 220 is the clamping space 210, and at least part of the target force application component is inserted into the mating sleeve 220 to drive the clamping component 100 to rotate. By setting the mating sleeve 220, it is convenient to cooperate with the target force application component. The plug-in method can be directly adopted, and the target force application component can be directly inserted into the mating sleeve 220, with a simple structure and convenient operation.

[0029] In the embodiment provided by the present application, the cross-section of the clamping space 210 along the radial direction of the mating sleeve 220 is a polygon. Preferably, the radial cross-section of the clamping space 210 is a quadrilateral or a hexagon. In this way, during the rotation of the target force application component, a stopping effect can be formed between the inner wall surface of the clamping space 210 to drive the clamping component 100 to rotate.

[0030] To facilitate the clamping of the target workpiece, the second clamping body 120 is rotatably arranged relative to the first clamping body 110 around the first axis. The clamping mechanism further includes: a locking assembly 300, at least part of the locking assembly 300 is arranged on the first clamping body 110, and the locking assembly 300 is detachably connected to the second clamping body 120 to connect the first clamping body 110 and the second clamping body 120. Through the locking assembly 300, the first clamping body 110 and the second clamping body 120 are kept in the clamping state to clamp the target workpiece. When it is necessary to release the target workpiece, the locking assembly 300 is separated from the second clamping body 120.

[0031] Specifically, as Figure 1 and Figure 2 shown, the second connection end 121 of the second clamping body 120 is pivotally connected to the first connection end 111 of the first clamping body 110 through a first rotating shaft 140; the locking assembly 300 includes: a fixing plate 310 arranged at the first locking end 112 of the first clamping body 110; a locking plate 320 arranged at the second locking end 122 of the second clamping body 120, and a clamping groove 321 is arranged on the locking plate 320; a fastener 330, one end of the fastener 330 is pivotally connected to the fixing plate 310, and the other end of the fastener 330 is clamped in the clamping groove 321 and is in interference fit with the clamping groove 321. Through the clamping between the fastener 330 and the clamping groove 321, a pulling force in the direction towards the first clamping body 110 is applied to the second clamping body 120, so that the second clamping body 120 and the first clamping body 110 are kept in the clamping state.

[0032] Further, an extending plate body 311 is arranged on the fixing plate 310, and a predetermined angle is formed between the extending direction of the extending plate body 311 and the fixing plate 310. The locking assembly 300 further includes: an operating handle 340, the fastener 330 is arranged on the operating handle 340, and the operating handle 340 is pivotally connected to the extending plate body 311, and the fastener 330 is driven to rotate by the operating handle 340. During use, by rotating the operating handle 340, the operating handle 340 drives the end of the fastener 330 away from the clamping groove 321 to rotate, so that the fastener 330 is separated from the clamping groove 321, and the second clamping body 120 is opened to release the target workpiece; during the clamping process, the second clamping body 120 is rotated towards the direction close to the first clamping body 110, the fastener 330 is first clamped in the clamping groove 321, and then the operating handle 340 is rotated towards the direction close to the first clamping body 110 to generate a pulling force on the fastener 330, so as to lock the second clamping body 120 and the first clamping body 110.

[0033] In the specific implementation process, the locking assembly 300 further includes: a connecting pin shaft 350. The connecting pin shaft 350 is inserted through the operating handle 340. A through hole 3501 is provided on the connecting pin shaft 350. At least a part of the fastener 330 is inserted into the through hole 3501 and connected to the connecting pin shaft 350. Preferably, the fastener 330 is movably arranged relative to the connecting pin shaft 350. An external thread is provided at the end of the fastener 330. After the end of the fastener 330 passes through the through hole 3501, it is locked by a nut. Nuts are respectively arranged on both sides of the connecting pin shaft 350 and threadedly connected to the fastener 330. When it is necessary to adjust the tension of the fastener 330, the nut can be removed to move the fastener 330.

[0034] As Figure 3 shown, through holes 3501 are respectively provided at both ends of the connecting pin shaft 350. The fastener 330 includes: a first body 3301, a second body 3302, and a third body 3303 that are sequentially connected along a broken-line trajectory. The first body 3301 and the third body 3303 are respectively inserted into the two through holes 3501 and connected to the connecting pin shaft 350. At least a part of the second body 3302 is engaged in the card slot 321. Such a setting enables the fastener 330 to utilize the second body 3302 to engage with the card slot 321, and the first body 3301 and the third body 3303 are connected to the connecting pin shaft 350, so as to provide sufficient tension to the second clamping body 120.

[0035] Furthermore, the locking assembly 300 further includes: a second rotating shaft 360. The second rotating shaft 360 is sequentially inserted through the operating handle 340 and the protruding plate body 311, so that the operating handle 340 rotates around the second rotating shaft 360. The second rotating shaft 360 is located on the side of the connecting pin shaft 350 close to the locking plate 320.

[0036] In the embodiment provided by the present application, a positioning protrusion is provided on the target workpiece, and a positioning groove is provided on the inner wall surface of the clamping space 130. At least a part of the positioning protrusion is inserted into the positioning groove to position the target workpiece. Among them, the target workpiece is a pipe fitting joint. A positioning protrusion is provided on the surface of the pipe fitting joint, and the positioning protrusion is arranged along the circumferential direction of the pipe fitting joint. In this way, during the clamping process, the phenomenon of slipping between the pipe fitting joint and the inner wall surface of the clamping space 130 can be avoided.

[0037] The clamping mechanism provided by the present application can clamp the pipe fitting joint, apply a force to the clamping component 100 by using the target force-applying component, thereby driving the pipe fitting joint to rotate, and installing the pipe fitting joint at a specified position. The installation is convenient and the operation is simple and fast. Torque control can be performed on the cylindrical pipe joint. The target force-applying component can be selected as a wrench that matches the inner wall surface of the engaging space 210. When the radial cross-section of the engaging space 210 is hexagonal, an internal hexagonal wrench can be used to operate the clamping component 100.

[0038] When operating the clamping mechanism of the present application, after opening the second clamping body 120 and clamping it on the pipe joint, swing the operating handle to make the fastener stuck in the corresponding clamping groove 321 of the locking plate 320, and press the operating handle to clamp the water pipe joint. The force application part is designed according to the mating dimensions of the torque wrench. When tightening, only an external torque wrench is needed to tighten the pipe joint and control the torque.
