[0019] The following will be combined with the Figure 1 -attached Figure 4 The utility model will be further explained in detail as follows:

[0020] The utility model discloses a kind of slip rings based on multi-channel transmission, as shown in Figure 1 、 Figure 3 、 Figure 4As shown, this utility model discloses a slip ring based on multi-channel transmission, comprising a housing 1 and a rotor 2. The rotor 2 is rotatably connected to the inside of the housing 1 via bearings. The inner wall of the housing 1 is provided with several sliding seats 3, each of which has a stator probe 4 slidably connected inside. Each sliding seat 3 has an elastic element 5 inside to prevent the stator probe 4 from moving towards the rotor 2. The outer wall of the housing 1 is provided with several threaded seats 6, which are connected to and correspond one-to-one with the sliding seats 3. Each threaded seat 6 has a bolt 7 threadedly connected inside, which can push the stator probe 4 into contact with the rotor 2. In this embodiment, the shape of the stator probe 4 is as follows: Figure 4 As shown. The sliding seat 3 is a hollow cylinder with a through hole on its side wall near the rotor 2. The end of the stator probe 4 passes through this through hole and contacts the rotor 2. The function of the elastic element 5 is to push the stator probe 4 away from the rotor 2 when the bolt 7 is not pushing it into contact with the rotor 2. The threaded seat 6 has a threaded hole inside, which is connected to the inside of the sliding seat 3. The bolt 7 is threadedly connected to the threaded seat 6 through this threaded hole. When the bolt 7 is screwed in, the end of the bolt 7 can abut against the end of the stator probe 4 and push the stator probe 4 into contact with the rotor 2. At this time, the spring is in a compressed state. When the bolt 7 is unscrewed, the spring will restore its deformation and push the stator probe 4 away from the rotor 2, so that the stator probe 4 is disconnected from the rotor 2. Preferably, the elastic element 5 is a spring, one end of which abuts against the inner side wall of the sliding seat 3, and the other end of the spring abuts against the stator probe 4. Preferably, the number of sliding seats 3, stator probes 4, elastic elements 5, threaded seats 6, and bolts 7 are all N, where N≥2. By setting multiple sliding seats 3 and stator probes 4 on the inner sidewall of the housing 1, multi-channel transmission is achieved. The design of threaded seats 6 and bolts 7 allows for adjustment of different transmission channels. It can be determined whether each transmission channel is connected according to the actual usage. Multiple sliding seats 3 and stator probes 4 can be reserved for expansion. When in use, tightening the bolts 7 can connect the transmission channel, thereby avoiding the need to replace the entire slip ring, reducing costs, and increasing service life.

[0021] like Figure 3 As shown, the stator probe 4 is connected to a stator wire 41 at the end away from the rotor 2. The stator wire 41 extends through the housing 1 to the outside of the housing 1. In this embodiment, the stator wire 41 is the connection medium between the transmission channel and the external device. Each stator wire 41 is connected to a stator probe 4. Different transmission channels can be identified / distinguished by assigning numbers to the stator wires 41 or by assigning different colors to the stator wires 41.

[0022] like Figure 2As shown, the side wall of the shell 1 is provided with a plurality of lightening grooves 8, the lightening grooves 8 are arranged away from the position of the sliding seat 3; in the embodiment, by opening the lightening grooves 8 on the side wall of the shell 1, the weight of the slip ring is effectively reduced while ensuring the strength of the slip ring structure, which is convenient for installation and carrying.

[0023] As shown in the drawings, Figure 1 As shown, the top of the shell 1 is integrally formed with a mounting flange 9 for mounting the slip ring; in the embodiment, by arranging the mounting flange 9, the installation of the slip ring is more convenient and fast, and the installation efficiency is improved.

[0024] The implementation principle of the embodiment of the utility model is:

[0025] When the bolt 7 is screwed in, the end of the bolt 7 can abut against the end of the stator probe 4, with the increase of the screwing amount of the bolt 7, the stator probe 4 gradually moves to the rotor 2 direction and compresses the spring in the process, until the stator probe 4 contacts the rotor 2;

[0026] When the bolt 7 is unscrewed, the spring will recover the deformation and push the stator probe 4 to move away from the rotor 2, so that the stator probe 4 is disconnected with the rotor 2.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the prior art, which should be understood by the technicians in the industry. The utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed.
