The present application has the effect of separating adjacent core wires and reducing the conduction of electricity between the core wires due to mutual friction;

[0005] However, in the above scheme, the spring wire is always in a stretched state during use, which will cause the spring wire to gradually lose its elasticity, making the spring wire lose its effect and having a short service life. Due to the characteristics of the spiral setting of the spring wire during use, the electromagnetic interference between the coils is relatively serious, and the current passing through the spring wire during use will cause the cable temperature to rise.

[0006] For this purpose, we propose a wear-resistant reinforced spring wire. Utility Model Content

[0009] Preferably, the elastic component comprises a shell, a fixed shaft is fixedly connected inside the shell, winding plates are sleeved at both ends of the fixed shaft, a coil spring is fixedly connected to the outer side of the fixed shaft, and the coil spring is arranged between two winding plates.

[0010] Preferably, one end of the coil spring away from the fixed axis is fixedly connected to a connector, one side of the connector is fixedly connected to a steel cable, and the steel cable is also wound around the coil spring.

[0011] Preferably, one end of the shell is fixedly connected to a wire outlet pipe that passes through the support plate, and the steel cable is pulled out from the wire outlet pipe. Both sides of the shell are fixedly connected to fixing plates, and the fixing plates are fixedly connected to the support plate.

[0012] Preferably, the spring wire comprises a spring core, the spring core is wrapped with an anti-wear sleeve, and a plurality of cables are wound around the anti-wear sleeve.

[0013] Preferably, the cable is covered with a shielding sleeve, the cables are filled with a first thermally conductive sponge, and a plurality of tensile ropes are wrapped around the shielding sleeve.

[0014] Preferably, the second heat-conductive cotton is filled between the anti-tension ropes, and the anti-tension ropes are covered with a wear-resistant sleeve.

[0015] The utility model provides a wear-resistant reinforced spring wire, which has the following improvements and advantages compared with the prior art:

[0016] (1) The utility model adopts an elastic component to compensate for the elasticity of the spring wire. An input head is arranged at one end of the spring wire, and the input head passes through the support plate.

Fixed plates are fixedly connected on both sides of the shell. The fixed plates are fixedly connected to the support plate. By arranging the disc spring, when the spring wire is stretched, the stretching force will be shared by the disc spring, thereby reducing the load of the spring wire and increasing the elastic coefficient of the spring wire. This makes the spring wire more reliable and can extend the elastic drop speed of the spring wire, thereby extending its service life.

The end of the coil spring 26 away from the fixed shaft 24 is fixedly connected to a connector 27, and one side of the connector 27 is fixedly connected to a steel cable 28. The steel cable 28 is also wound on the coil spring 26. When the steel cable 28 is pulled out, the connector 27 is pulled out, thereby driving the coil spring 26 to contract. An outlet pipe 23 that penetrates the support plate 29 is fixedly connected to one end of the housing 21. The function of the outlet pipe 23 is to extend the steel cable 28, and the steel cable 28 is pulled out from the outlet pipe 23.

The fixed plates 22 are fixedly connected to the support plate 29, and the function of the fixed plates 22 is to fix the housing 21;

[0028] In the present embodiment, by connecting the input head 31 to a fixed external device, the movable plate 30 is pulled to stretch the spring wire 10 to extend its usable length. While the spring wire 10 is stretched, the steel cable 28 is pulled out from the coil spring 26, and the coil spring 26 contracts to accumulate elastic potential energy, thereby replenishing the elastic coefficient of the spring wire 10. The force of the stretching of the spring wire 10 will be shared by the coil spring 26, reducing the load on the spring wire 10, making the spring wire 10 more reliable, and being able to extend the elastic drop rate of the spring wire 10, thereby extending its service life.
