Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cable joint pressure testing, and in particular to a high-efficiency external hydraulic pressure testing tool for a cable joint. Background Art
[0002] At present, there are two main forms of external hydraulic test fixtures for cable joints: one is an integral structure, which is a sealing tube type. A sealing structure is designed at the open end of the sealing tube. During the test, the cable joint is inserted into the inner cavity of the sealing tube and sealed by an O-ring. The sealing connection between the cable joint and the sealing tube is ensured by the external hydraulic test pressure. The integral test fixture does not require fastening and has a simple structure and quick operation. However, the separation of the cable joint and the sealing tube after the external hydraulic test can only be achieved by pulling, which is difficult to operate and is very likely to cause damage to the cable joint during the separation process.
[0003] The other is a split structure, which consists of a sealing tube and a sealing cover. The sealing cover is provided with two sets of sealing structures, one set for sealing connection with the cable connector, and the other set for sealing connection with the sealing tube. Both the sealing tube and the sealing cover are provided with connecting flanges, and multiple connecting holes are distributed on the flanges, and the two are connected by screws. Before the external hydraulic test, the cable connector and the sealing cover are first sealed and connected, and then the sealing cover with the cable connector and the sealing tube are sealed and connected through O-rings and screws. After the external hydraulic test, the screws are removed to disengage the sealing cover and the sealing tube, and then the cable connector and the sealing cover can be separated by gently pushing the open end of the cable connector. The split structure can realize the assembly and disassembly requirements of the cable connector and the test fixture, but multiple sets of screws need to be installed and disassembled before and after the test, which is inefficient. Summary of the invention
[0004] In view of the problems existing in the above-mentioned existing high-efficiency external hydraulic test tooling for cable joints, the present invention is proposed.
[0005] Therefore, the purpose of the present invention is to provide a high-efficiency external hydraulic test fixture for cable joints, which solves the problem that the existing external hydraulic test fixture for cable joints needs to remove multiple sets of screws during installation, thereby resulting in low test efficiency.

[0007] Preferably, the sealing cylinder is a cylindrical structure with one end open, and is made of aluminum alloy.
[0008] Preferably, the upper surface of the sealing cylinder is provided with a plurality of internal threaded holes matching corresponding screws.
[0009] Preferably, a sealing groove is formed around the upper surface of the sealing cylinder.
[0010] Preferably, a second O-ring is disposed inside the sealing groove.
[0011] Preferably, the size of the nut is smaller than the size of the disassembly clearance hole and larger than the size of the screw through hole.
[0012] In the above technical solution, the technical effects and advantages provided by the present invention are: 1. The present invention, by putting a first O-ring on the outer surface of the cable connector, then putting the cable connector into the interior of the cover, then combining the cover and the sealing tube, and then fixing the cover and the sealing tube by each screw and nut.

This process does not require the installation and disassembly of multiple sets of screws.
[0013] 2. The present invention can play a sealing role through the second O-ring, thereby improving the sealing performance between the sealing tube and the sealing cover. BRIEF DESCRIPTION OF THE DRAWINGS
