[0040] In this embodiment, the mounting structure 12 is mounted on the support structure and is used for sealing the pipe fittings. A movable limiting structure 20 is slidably connected to the support structure. The movable limiting structure 20 is connected to the drive unit 30. The drive unit 30 drives the movable limiting structure 20 to move, and then the movable limiting structure 20 fixes or releases the pipe fittings on the mounting structure 12.

[0041] The quick-change sealing and testing fixture for pipe fittings provided in this embodiment of the utility model, compared with the prior art, features an installation structure 12 on which the pipe fitting is mounted. The installation structure 12 is mounted on a supporting structure, and a movable limiting structure 20 is slidably connected to the supporting structure. The movable limiting structure 20 is also connected to a drive unit 30, allowing the drive unit 30 to drive the movable limiting structure 20 to fix or release the pipe fitting on the installation structure 12. In this application, the installation structure 12 seals and fixes the pipe fitting, and then the movable limiting structure 20 fixes and limits the pipe fitting, thus ensuring the stability of the pipe fitting. The drive unit 30 drives the movable limiting structure 20 to fix or release the pipe fitting on the installation structure 12, reducing the labor intensity of workers, improving work efficiency, and enhancing practicality.

In this embodiment, the mounting structure 12 is disposed on the support surface, and there are two support frames 11. The two support portions 111 jointly support the mounting structure 12 to ensure structural stability. The connecting portion 112 is integrally connected to the support portion 111, and a sliding groove 114 is provided on the connecting portion 112. The movable limiting structure 20 is slidably disposed in the sliding groove 114.

[0043] In some embodiments, please refer to Figures 1 to 3 The first direction is defined as the spacing between the two support frames 11. The movable limiting structure 20 includes two limiting blocks 21, which are correspondingly arranged with the two support frames 11. Each limiting block 21 is slidably connected to its corresponding connecting part 112 along the first direction. The driving unit 30 drives the two limiting blocks 21 to move towards or away from each other. In this embodiment, when the pipe needs to undergo a sealing test, the two limiting blocks 21 move towards each other to clamp and fix the pipe. The two limiting blocks 21 work together to clamp and limit the pipe, ensuring the stability of the pipe installation. After the pipe sealing test is completed, the limiting blocks 21 are moved away from each other, releasing the pipe and facilitating its removal. This operation is convenient.

[0044] In some embodiments, please refer to Figure 1 and Figure 2 Each limiting block 21 has an arc-shaped abutment clamping part 211. In this embodiment, the arc-shaped clamping part is adapted to the shape of the pipe fitting, making the clamping of the pipe fitting more stable.

[0045] In some embodiments, please refer to Figure 1 The drive unit 30 includes drive components 31 and elastic connectors 32. Two drive components 31 are provided, each corresponding to one of the two support frames 11.

Both ends of the elastic connector 32 are connected to the two drive components 31. In this embodiment, the two drive components 31 are connected via the elastic connector 32, so that when the elastic connector 32 is in a compressed or extended state, the positions of the two drive components 31 can be adjusted. Since each drive component 31 is connected to a corresponding limiting block 21, adjusting the two drive components 31 can cause the two limiting blocks 21 to move towards or away from each other.

[0046] Specifically, the elastic connector 32 can be a spring.

[0047] In some embodiments, please refer to Figures 1 to 3 Each drive assembly 31 includes a grip lever 311 and an actuating member 312. The grip lever 311 has a first grip end and a second grip end. The first grip end is for gripping, and the second grip end is connected to an elastic connector 32. The actuating member 312 has a first actuating end and a second actuating end. The first actuating end is hinged to the second grip end, and the second actuating end is connected to a corresponding limiting block 21. The actuating member 312 is rotatably connected to the support frame 11.

In this embodiment, the first end of the grip rod 311 is for hand gripping, the first end of the actuating member 312 is hinged to the second end of the grip rod, and the second end of the actuating member 312 is connected to the corresponding limiting block 21. At the same time, the actuating member 312 is rotatably connected to the support frame 11. Thus, when the pipe to be tested needs to be installed, the hand grips the grip rod 311, the elastic connector 32 is compressed, the actuating member 312 rotates, and the actuating member 312 drives the two limiting blocks 21 to move in opposite directions. The limiting blocks 21 move into the slide groove 114, the pipe to be tested is inserted into the installation structure 12, the hand grips the grip rod 311 is released, and under the elastic force of the elastic connector 32 returning to its natural state, the hand grips the grip rod 311 drives the actuating member 312 to rotate in the opposite direction. The actuating member 312 drives the two limiting blocks 21 to move towards each other, and the limiting blocks 21 slide out of the slide groove 114, thereby achieving clamping and fixing of the pipe to be tested, that is, completing the installation operation of the pipe to be tested.

[0048] Preferably, the connecting part 112 is provided with a relief opening 113 to facilitate the free rotation of the actuating member 312. The actuating member 312 may be a ball-joint hinged fork.

[0049] In some embodiments, please refer to Figures 1 to 3 The grip lever 311 includes a handle 3111, a connecting rod 3112, and a connecting rod 3113. The handle 3111 is for gripping. One end of the connecting rod 3112 is connected to the handle 3111, and one end of the connecting rod 3113 is connected to the other end of the connecting rod 3112. The other end of the connecting rod 3113 is hinged to the actuating member 312. The connecting rod 3113 is connected to an elastic connecting member 32, which is located above the connecting rod 3112. Specifically, the elastic connecting member 32 is parallel to the connecting rod 3112. In this embodiment, the handle 3111 is connected to the connecting rod 3112, the connecting rod 3112 is connected to the connecting rod 3113, and the connecting rod 3113 is hinged to the actuating member 312. When the handle 3111 is gripped, the connecting rod 3113 compresses the elastic connecting member 32, and the actuating member 312 rotates to move the limiting block 21. The elastic connector 32 can be compressed directly by holding the handle 3111, making the operation convenient.

[0050] Specifically, the handle 3111 can be a nylon handle.

[0051] In some embodiments, please refer to Figure 1 The drive unit 30 also includes auxiliary support columns 33. Two auxiliary support columns 33 are provided, each positioned at the connection point between the elastic connector 32 and the two connecting rods 3113, with the elastic connector 32 sleeved on the two auxiliary support columns 33. Preferably, the two auxiliary support columns 33 are arranged parallel to the adapter rod 3112, and the length of the two auxiliary support columns is less than the length of the adapter rod 3112. In this embodiment, auxiliary support columns 33 are respectively provided at the connection points between the elastic connector 32 and the connecting rods 3113. The auxiliary support columns 33 are used to support the elastic connector 32, preventing bending deformation and ensuring the service life and performance of the elastic connector 32.

[0052] In some embodiments, please refer to Figure 1 and Figure 2 The mounting structure 12 has an open cylindrical cavity 121 for installing pipe fittings. In this embodiment, the cylindrical cavity 121 is adapted to the pipe fitting, facilitating the sealing installation of the pipe fitting. The sealing of the pipe fitting is installed in the mounting structure 12. Preferably, the open end of the cylindrical cavity 121 must be tapered, generally recommended to be R1-R2, with a taper of 25°~30°. Specifically, in this embodiment, the taper of the open end is selected as 25°.

[0053] A specific embodiment of the quick-change sealing test fixture for pipe fittings provided by this utility model is as follows: First, hold the handle 3111 with one hand. The elastic connector 32 is compressed, and the connecting rod 3113 drives the actuating element 312 to open outward. The actuating element 312 moves the limiting block 21 to slide outward parallel along the slide groove 114 until its head retracts into the slide groove 114. At this time, insert the pipe fitting to be tested into the mounting structure 12 until the end face of the pipe fitting contacts the bottom of the cylindrical cavity 121 of the mounting structure 12. Release the handle 3111. Under the elastic force of the elastic connector 32 returning to its natural state, the connecting rod 3113 drives the actuating element 312 to close inward. The actuating element 312 moves the limiting block 21 to slide inward and extend out of the slide groove 114, thereby blocking the pipe fitting to be tested in the groove, thus completing the installation operation of the quick-change sealing fixture. After installing the sealing plug fixtures one by one, connect the vent end of the assembly to be tested to the helium testing equipment, turn on the equipment to perform the sealing test, and after the test is completed and qualified, directly grasp the handle 3111, the elastic connector 32 is compressed, the limit block 21 retracts into the slide groove 114, and the installation structure 12 can be directly pulled out along the axial direction of the pipe.
