Description

Technical Field

[0001] This utility model relates to the field of electric slip rings, specifically an electric slip ring with a protective mechanism. Background Technology

[0002] An electrical slip ring, also known as a conductive slip ring or a rotary electrical interface, is a precision device that enables the transmission of electrical or data signals from a fixed position to a rotating position while rotating continuously without restriction. To improve the protection level and reliability of the electrical slip ring, and to increase its service life and normal operation, various protective mechanisms are incorporated into the structure of the electrical slip ring. Electrical slip rings with protective mechanisms are widely used in various applications that require the transmission of electrical or data signals while rotating continuously without restriction.

[0003] Commonly used slip rings are directly installed inside the equipment and exposed to air for a long time. This can easily cause dust and impurities to accumulate on the surface and inside the slip ring. Dust accumulation can affect the contact between the conductive ring and the brush, thus affecting conductivity and wear resistance.

[0004] Therefore, this utility model proposes an electric slip ring with a protective mechanism to solve the problems mentioned above. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The electric slip ring with a protective mechanism proposed in this utility model utilizes a mounting plate, a housing, a dustproof net, and a movable plate in conjunction with each other. The mounting plate facilitates the installation and use of the electric slip ring, while the housing can surround the electric slip ring, preventing most of the dust and impurities from entering the slip ring and affecting its normal operation.

[0022] Please see Figures 1-4 This utility model provides a technical solution: an electric slip ring with a protective mechanism, the electric slip ring with the protective mechanism includes: an electric slip ring 1, a side wall mounting plate 3 of the electric slip ring 1, a housing 2 mounted on the side wall of the mounting plate 3, the housing 2 being located on the outer surface of the electric slip ring 1, a movable plate 10 mounted on the side wall of the mounting plate 3, a dustproof net 9 mounted on the side wall of the housing 2, the movable plate 10 being located on the inner wall of the housing 2 and movable inside the dustproof net 9, and the size of the movable plate 10 being the same as the size of the dustproof net 9;

[0023] During use, the mounting plate 3 facilitates the installation and use of the electric slip ring 1, while the outer shell 2 can surround the electric slip ring 1 to prevent most of the dust and impurities from entering the slip ring and affecting its normal operation. The use of the dustproof net 9 helps the heat inside the electric slip ring 1 to dissipate during use. The movable plate 10 can slide on the side wall of the outer shell 2, making it convenient to cover the dustproof net 9 when heat dissipation is not required, thus preventing dust from entering the slip ring through the mesh.

[0026] Before using the electric slip ring 1, pull the lever 4 outward to lock the chuck 5 into the slot 8 of the rotating drum 6 and fix it in place. Then rotate the lever 4 to drive the rotating drum 6 to rotate, which in turn drives the cleaning brush 7 to rotate, cleaning the dust on the outer surface of the electric slip ring 1 and preventing dust from getting stuck in the slip ring and affecting the performance of the electric slip ring 1.

Before using the slip ring 1, pull the lever 4 outward to make the chuck 5 lock into the slot 8 of the rotating drum 6 and fix it in place. The rotating lever 4 drives the rotating drum 6 to rotate, which in turn drives the cleaning brush 7 to rotate, cleaning the dust on the outer surface of the electric slip ring 1 and preventing dust from getting stuck inside the slip ring, which would affect the performance of the electric slip ring 1. When the outer shell 2 is installed and fixed with the mounting plate 3, the top of the rotating rod 15 is fixed with the rotating shaft 12.
