[0002] Conductive slip ring is an electrical component that can transmit and transfer signals and power between two relatively rotating mechanisms. It is generally widely used. It mainly consists of two parts: stator and rotor. Conductive slip ring can be divided into solid slip ring and hollow slip ring. However, hollow slip ring has the problems of low strength, easy deformation and easy force concentration. There are also some means to improve the service life of slip ring in the existing technology, but these means do not strengthen the stability of the shaft of hollow slip ring. As one of the important components of slip ring, the shaft directly affects the performance and service life of slip ring. Utility Model Content

[0017] The present invention will be further described below in conjunction with specific embodiments. The present invention is explained through the exemplary embodiments and descriptions of the present invention, but is not intended to limit the present invention.

[0018] Example 1: Figures 1-4 The conductive slip ring with a reinforced shaft shown in the figure includes a base plate 1, which can realize functions such as connecting and installing wires. A shaft body 2 is fixed on one side of the base plate 1, and an inner shaft groove 3 is provided on the inner side of the shaft body 2, making the slip ring easier to install.

[0019] At least one reinforcing rib 4 is provided on the inner side of the inner groove 3 of the shaft. The reinforcing rib 4 and the shaft body 2 can be formed as an integral part, so that the overall stress-bearing capacity of the shaft body 2 is improved. The length of the reinforcing rib 4 is three-quarters of the length of the inner groove 3 of the shaft. Through this arrangement, the reinforcing rib 4 can complete the support work of the shaft body 2, and a reserved wire outlet space 6 is provided on the inner side of the inner groove 3 and at one end away from the reinforcing rib 4. The reserved wire outlet space 6 is the remaining one-quarter of the space of the inner groove 3, and the arrangement of the reserved wire outlet space 6 facilitates the outlet of the conductive slip ring and reduces the shaking of the wire.

[0020] In addition, an arc-shaped surface 5 is provided at the connection between the reinforcing rib 4 and the shaft body 2, which can reduce the stress concentration problem during the rotation of the slip ring, thereby further increasing the stress-bearing strength of the conductive slip ring. The reinforcing rib 4 is located at the center of the inner groove 3 of the shaft and divides the inner groove 3 into two identical groove bodies. By locating the reinforcing rib 4 at the exact center, the force borne by the shaft body 2 is more uniform, thereby extending the service life of the shaft body 2.

[0021] From the above structure, it can be known that when the shaft body 2 is installed on the shaft, etc., the reinforcing rib 4 at the center position can provide a certain supporting force for the shaft body 2, thereby improving the strength of the columnar hollow slip ring.

[0022] Example 2: This example is a further technical improvement based on Example 1; its technical structure and effect are as follows; an extended movable plate 7 is provided on the inner side of the inner groove 3 of the shaft and on both sides of the reinforcing rib 4, and the extended movable plate 7 and the shaft body 2 are in interference fit. Through this arrangement, when the extended movable plate 7 moves on the inner side of the shaft body 2, it will not easily produce a moving effect unless it is manually pushed, thereby ensuring the stability of the extended movable plate 7. The extended movable plate 7 is made of the same material as the reinforcing rib 4 and the shaft body 2, and can be a structure with strong interference stress such as metal. The upper and lower parts of the extended movable plate 7 are both provided with an arc-shaped body 8 corresponding to the arc-shaped surface 5. The arc-shaped body 8 can provide the same effect as the arc-shaped surface 5 when extended, thereby reducing the stress concentration problem during the rotation of the slip ring, and a locking structure is provided between the extended movable plate 7 and the reinforcing rib 4.

[0023] The locking structure specifically includes an installation groove arranged on the extended movable plate 7, the inner side of the installation groove is fixedly connected to the fixed plate, a plurality of clamping blocks are arranged on the side of the fixed plate away from the extended movable plate, and a plurality of clamping grooves are arranged on both sides of the reinforcing rib 4 and corresponding to the clamping blocks, so that precise positioning and fixation can be achieved.

[0024] The clamping blocks are made of soft material, which provides better adaptability and can adapt to components of different shapes and sizes. The number of clamping slots is greater than the number of clamping blocks, making the conductive slip ring more stable and smooth during rotation. At the same time, this design also makes the conductive slip ring more convenient and efficient during manufacturing and assembly.

[0025] Any matters not described in this utility model are applicable to the prior art.
