[0003] Due to the existing assembly method of the sealing surface retaining ring, it is often to squeeze and sleeved the sealing surface retaining ring on the component to be assembled by fingers. However, since the sealing surface retaining ring is prone to deformation and shrinkage during the squeezing and sleeving process, the sealing surface retaining ring is likely to fall off, and it needs to be squeezed several times to ensure that it does not fall off, which is time-consuming and laborious. Moreover, the manual assembly method has low efficiency, unstable quality, and long-term operation is likely to cause worker fatigue, thereby affecting the assembly quality. Utility Model Content

[0006] By adopting the above technical solution, by rotating and moving the pressing nut downward, the pressing nut moves downward and causes the pressing block to also move downward, so that the sealing surface retaining ring is pressed against the sealing surface of the component to be assembled through the pressing ring, completing the assembly, thereby improving the assembly efficiency and assembly quality of the sealing surface retaining ring, reducing the labor intensity of workers, and reducing the influence of human factors on the assembly quality.

[0007] Optionally, a first handle is fixedly installed on one outer surface of the fixed seat, and anti-slip pads are sleeved on both the first handle and the second handle.

[0010] With the above technical solution, the installation of the pressing ring and the fixing column is facilitated by setting the internal thread and the external thread.

[0011] Optionally, two card slots are symmetrically opened at one end of the fixing seat, and two clamping blocks are slidably installed in the two card slots, and the two clamping blocks are fixedly connected to the pressing ring.

[0012] With the above technical solution, the installation and fixation can be strengthened by setting the card slot and the clamping block.

[0013] Optionally, the same insertion hole is opened on the fixing seat and the two clamping blocks, and a plug rod is slidably installed in the insertion hole.

[0014] With the above technical solution, the plug rod can be slidably installed inside by setting the insertion hole.

[0015] Optionally, second threads are opened on the outer surfaces of both sides of the plug rod, and nuts are screwed on the two second threads.

[0016] With the above technical solution, by rotating the two nuts and removing the two nuts, the plug rod can also be removed at this time, so that the pressing ring can be removed, and then the pressing ring can be removed and replaced conveniently. Therefore, the pressing ring can be replaced according to the size of the sealing surface retaining ring to be assembled.

[0017] Optionally, the first thread is longer than the second thread, and anti-slip threads are provided on both nuts.

[0018] With the above technical solution, it is convenient for installation and use because the first thread is longer than the second thread.

[0019] In summary, the beneficial effects of this application are as follows:

[0020] 1. In this new type of application, with the cooperation of components such as the pressing ring, by rotating the second handle, the second handle rotates and drives the compression nut to rotate and move downward. The compression nut moves downward and causes the pressing block to also move downward, so that the sealing surface retaining ring is pressed against the sealing surface of the component to be assembled through the pressing ring, completing the assembly. Thus, the assembly efficiency and assembly quality of the sealing surface retaining ring are improved, the labor intensity of workers is reduced, and the influence of human factors on the assembly quality is reduced.

[0021] 2. In this new type of application, with the cooperation of components such as the plug rod, by rotating the two nuts and removing the two nuts, the plug rod can also be removed at this time, so that the pressing ring can be removed, and then the pressing ring can be removed and replaced conveniently. Therefore, the pressing ring can be replaced according to the size of the sealing surface retaining ring to be assembled. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1-3 , an assembly device for a sealing surface retaining ring, including a fixed seat 1, on which a pressing ring 3 is detachably installed. By setting the pressing ring 3, the auxiliary assembly of the sealing surface retaining ring can be carried out. A fixed column 4 is detachably installed inside the pressing ring 3. A circular sleeve 6 is rotatably sleeved on the fixed column 4. A pressing block 5 is fixedly installed on the circular sleeve 6. By setting the pressing block 5, an auxiliary driving effect can be achieved. A first thread 7 is provided on the outer surface of the fixed column 4, and a compression nut 8 is screwed on the first thread 7. The compression nut 8 is fixedly connected to the circular sleeve 6. A second handle 9 is fixedly installed on the outer surface of one side of the compression nut 8.

[0029] During use, by rotating and moving the compression nut 8 downward, the compression nut 8 moves downward and will cause the pressing block 5 to also move downward. Thus, the sealing surface retaining ring is pressed against the sealing surface of the component to be assembled through the pressing ring 3, completing the assembly. Thereby, the assembly efficiency and assembly quality of the sealing surface retaining ring are improved, the labor intensity of workers is reduced, and the influence of human factors on the assembly quality is reduced.

[0030] Referring to Figure 1 and Figure 2 , a first handle 2 is fixedly installed on the outer surface of one side of the fixed seat 1, and anti-slip pads are sleeved on both the first handle 2 and the second handle 9. By setting the anti-slip pads, the friction force can be increased.

[0031] Referring to Figure 2 and Figure 3, an internal thread 14 is provided in the pressing ring 3, and an external thread 15 is provided on the outer surface of the bottom of the fixing post 4. The internal thread 14 and the external thread 15 are adapted to each other. By providing the internal thread 14 and the external thread 15, it is convenient to install the pressing ring 3 and the fixing post 4.

[0032] Refer to Figure 3 , two clamping grooves 12 are symmetrically provided at one end of the fixing seat 1, and two clamping blocks 13 are slidably installed in the two clamping grooves 12. The two clamping blocks 13 are fixedly connected to the pressing ring 3. By providing the clamping grooves 12 and the clamping blocks 13, the function of strengthening the installation and fixation can be achieved.

[0033] Refer to Figure 3 and Figure 4 , the fixing seat 1 and the two clamping blocks 13 are provided with the same insertion hole 16, and a plug rod 10 is slidably installed in the insertion hole 16. By providing the insertion hole 16, the plug rod 10 can be slidably installed therein.

[0034] Refer to Figure 4 , second threads 17 are provided on the outer surfaces of both sides of the plug rod 10, and nuts 11 are screwed on the two second threads 17. By rotating the two nuts 11 and removing the two nuts 11, the plug rod 10 can also be removed at this time, so that the pressing ring 3 can be removed, and then it is convenient to disassemble and replace the pressing ring 3. Therefore, the pressing ring 3 can be replaced according to the size of the sealing surface retaining ring to be assembled.

[0035] Refer to Figure 2 and Figure 4 , the first thread 7 is longer than the second thread 17, and anti-slip threads are provided on both nuts 11. By the first thread 7 being longer than the second thread 17, it is convenient for installation and use.

[0036] The implementation principle of this application is as follows: When in use, first, the fixing seat 1 is fixedly installed with the component to be assembled, and then the pressing ring 3 is sleeved outside the sealing surface retaining ring to be assembled. At this time, the pressing block 5 is located above the pressing ring 3. Then, by rotating the second handle 9, the second handle 9 rotates and drives the pressing nut 8 to rotate and move downward. The pressing nut 8 moves downward and drives the pressing block 5 to move downward accordingly. Thus, the sealing surface retaining ring is pressed against the sealing surface of the component to be assembled through the pressing ring 3, completing the assembly. Furthermore, the assembly efficiency and assembly quality of the sealing surface retaining ring are improved, the labor intensity of workers is reduced, and the influence of human factors on the assembly quality is reduced;

[0037] By rotating the two nuts 11 and removing the two nuts 11, the plug rod 10 can also be removed at this time, so that the pressing ring 3 can be removed, and then it is convenient to disassemble and replace the pressing ring 3. Therefore, the pressing ring 3 can be replaced according to the size of the sealing surface retaining ring to be assembled.
