Description

Technical Field

[0001] The utility model relates to an oil plug, in particular to a split oil plug. Background Art

[0002] The rotary reducer contains many moving parts, such as gears and bearings. These parts will produce friction and wear during operation. By regularly adding lubricating oil to the reducer, the normal operation of the various parts inside the reducer can be ensured and failures and damage caused by friction and wear can be prevented.

[0003] Normally, a refueling hole is provided on the reducer for injecting lubricating oil. After refueling, the oil plug is screwed on. Most of the existing oil plugs are integrated and matched with the refueling hole through threads. However, repeated disassembly and assembly of the oil plug will cause the threads at the refueling hole of the machine body to wear out, and oil leakage will occur here over a long period of time. Once the threads at the refueling hole of the machine body are damaged, it is difficult to repair. Utility Model Content

[0004] Aiming at the problems that occur when using the traditional oil plug in the background technology, the utility model provides a split oil plug, which includes a mounting column and a sealing member;

[0005] The mounting column is provided with an axial through hole, an external thread is provided on the side surface of one end of the mounting column, and an internal thread is provided on the inner wall of the through hole at the other end of the mounting column;

[0006] The sealing piece is composed of a stud and a sealing cover. The sealing cover is fixedly connected to the end face of the stud. The external thread on the side of the stud matches the internal thread at the through hole of the mounting column. The stud of the sealing piece can be screwed into the through hole of the mounting column, and the sealing cover of the sealing piece can fit the corresponding end face of the mounting column.

[0007] The above-mentioned split oil plug has an installation column that can be installed at the refueling hole of the body through an external thread. After the installation of the installation column is completed, lubricating oil can be added to the inside of the body through its through hole. Finally, the sealing piece is screwed on according to the above-mentioned matching form to complete the refueling. The next time you need to refuel, you only need to remove the sealing piece that seals the split oil plug, and the threaded matching between the installation column and the refueling hole of the body does not need to be used. Compared with traditional oil plugs, it can avoid the risk of wear of the threads at the refueling hole of the body due to repeated disassembly.

[0008] Furthermore, a hexagonal block is integrally connected to the middle of the installation column, and the hexagonal block is used to fit a wrench to facilitate the screwing installation of the installation column.

[0009] Furthermore, the blocking piece is provided with a sealing ring at the connection between the stud and the cover, and the sealing ring is specifically an O-type rubber sealing ring, so that the sealing effect of the blocking piece is better.

[0010] Through the above technical solution, the utility model has at least the following beneficial effects:

[0011] The split oil plug described in the present application does not require changing the threaded structure of the original body's refueling hole and can be installed through its mounting column. When refueling is required, it is only necessary to remove the sealing part of the split oil plug, and the threaded cooperation between the mounting column and the body's refueling hole does not need to be used. Compared with traditional oil plugs, it can avoid the risk of wear of the thread of the body's refueling hole caused by multiple disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
