AI Technical Summary
The elbow fixing method of traditional railway track signal equipment only allows for incoming lines in one direction, resulting in forced twisting of the cable when operating in other directions, which can easily cause cable damage and communication failure, and may even lead to train suspension.
A rotatable adapter elbow is designed, through the connection between the elbow and the circular cover plate and the adapter cover plate, the grooves, bosses, sealing rings and sealing pads are used, combined with hexagonal bolts to achieve multiple elbows. Rotate direction, suitable for different routing directions.
It improves the flexibility and smoothness of the line, reduces damage to parts caused by disassembly and installation, extends service life, and ensures the safety and flexibility of the communication line.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of railway track signal lines, and in particular relates to a rotatable transfer elbow used for railway track signal equipment. Background Art
[0002] In the operation of railway lines, the protection of communication equipment is of great significance. In the protection of communication systems, boxes and switch machines are the most important track equipment, which play a certain role in the control and conversion of cables.
[0003] When the cable structure in the box or switch machine passes through the box body, it is often necessary to turn the cable. This kind of turning arrangement requires special guidance or fixation of the cable. Although the traditional method uses elbows for fixation, the line inlet is fixed in only one direction after the elbow is fixed to the transformer box. It is inconvenient to use for working conditions in other directions. Forcibly twisting the direction of the cable can easily cause damage to the cable over time. If it is not properly protected, it can easily cause communication failures or even train suspension problems. Utility Model Content
[0004] The purpose of the utility model is to solve the above-mentioned problem. The present application proposes a rotatable transfer elbow for railway track signal equipment. The elbow can be rotated to facilitate line entry in different directions.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotatable adapter elbow for railway track signal equipment, including 24 boxes and switch machines on the side of the railway track for installing the elbow, one end of the elbow is key-connected with a round cover plate, the diameter of the central circular hole of the round cover plate is larger than the diameter of the elbow, the round cover plate is connected to the adapter cover plate, and a groove for placing a sealing ring is provided at the port where the round cover plate is connected to the adapter cover plate, and a sealing rubber pad is provided under the adapter cover plate.
[0006] Furthermore: a groove is provided at the port where the elbow is connected to the round cover plate, and a boss matching the groove is provided at the connection between the round cover plate and the elbow.
[0007] Furthermore: the circular cover plate and the adapter cover plate are fixed by hexagonal bolts, and the adapter cover plate is fixed to the transformer box by hexagonal bolts.
[0008] Furthermore: square holes are provided at both ends of the adapter cover plate, and the adapter cover plate and the sealing rubber pad are fixed to the transformer box by hexagonal bolts.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] The utility model discloses a transfer elbow that can rotate and is suitable for a variety of wiring directions, thereby ensuring the high flexibility and smoothness of the line. When in use, there is no need to remove the elbow and adjust the direction according to the wiring direction of the wire threading tube and then reinstall it, thereby saving labor. Since the elbow and the box or the switch machine are connected by bolts, frequent disassembly and installation will cause damage to the parts. ... BRIEF DESCRIPTION OF THE DRAWINGS
