Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sliding contact line rails, in particular to an indicating device for a sliding contact line rail. Background Technique
[0002] The sliding contact line rail is mainly a special wire for supplying power to some mobile devices. Then, generally, what forms does the sliding contact line fall into? The copper body sliding wire has the characteristic of strong insulation, which enables good protection between the sliding wire and the insulating wire. Its advantages are obvious in high-temperature environments. With the increased contact area and always maintaining good contact with the ground, it is made by combining the advantages of a rigid body and a single-stage sliding wire.
[0003] The sliding contact line rail needs to be provided with an indicator light for safety indication. Its main function is to remind everyone that the sliding wire is powered. When overhauling the sliding wire, the power inspection operation can only be carried out after seeing that the indicator light of the sliding contact line is extinguished, so as to ensure the safety of the maintenance personnel. The indicator light of the sliding contact line can play the roles of indication, warning, and current display. However, at present, during the installation and indication of the sliding contact line rail, the indicator light does not have a structure for protecting the indicator light, and the externally moving workpieces or items are likely to collide with the indicator light, which will cause damage to the indicator light and affect the indication work of the indicator light for the sliding contact line rail. Therefore, we propose an indicating device for a sliding contact line rail to solve the above problems. Summary of the Utility Model

In the actual implementation process, first, the indicator light 4 is installed and fixed through the mounting holes 14 and the mounting plate 1, and then the power cord 13 is connected to the sliding contact track for power supply. When protecting the indicator light 4, the transparent protective inner cover 3 can block external collisions. After the transparent protective inner cover 3 is collided externally, it will drive the transparent protective inner cover 3 to slide inside the transparent protective outer cover 2, and at the same time, the extended spring 7 and the damper 10 will also contract. Then, through the contraction of the spring 7 and the damper 10, the impact force of the collision received by the transparent protective inner cover 3 can be buffered, and thus the internal indicator light 4 can be protected.
[0024] Optionally, the top end of the transparent protective inner cover 3 extends into the interior of the transparent protective outer cover 2, and the outer surface of the transparent protective inner cover 3 is slidably connected to the inner wall of the transparent protective outer cover 2. Two sliding holes 15 are formed in the inner wall of the transparent protective outer cover 2, and two sliders 16 are fixedly connected to the outer surface of the transparent protective inner cover 3. The mutually remote ends of the two sliders 16 respectively extend into the two sliding holes 15. In the actual implementation process, through the extension of the transparent protective inner cover 3 inside the transparent protective outer cover 2 and the cooperation of the sliding holes 15 and the sliders 16, the transparent protective inner cover 3 will slide up and down more stably, avoiding the phenomenon of deviation when the transparent protective inner cover 3 slides up and down.
[0025] Optionally, a cable groove 12 is formed on the upper surface of the mounting plate 1. The tops of the two indicator lights 4 are fixedly connected to power lines 13, and both power lines 13 are located inside the cable groove 12. During the actual implementation process, through the setting of the cable groove 12, the power lines 13 can be stored, and it is convenient to connect with the sliding contact rail by using the power lines 13.
[0026] Optionally, two dampers 10 are fixedly connected to the bottom surface of the mounting plate 1, and the bottoms of the two dampers 10 are fixedly connected to the inner bottom wall of the transparent protective inner cover 3. During the actual implementation process, through the setting of the dampers 10, the stability of the transparent protective inner cover 3 during sliding is enhanced, and the phenomenon of shaking when the transparent protective inner cover 3 slides up and down is avoided.
[0027] Optionally, the mutually remote ends of the two limit blocks 9 respectively extend into the two limit holes 8, and the outer surface of the limit block 9 is slidably connected to the inner wall of the limit hole 8. During the actual implementation process, through the sliding of the limit block 9 inside the limit hole 8, the sliding block 5 and the transparent protective inner cover 3 can be limited during sliding, and the problem of the transparent protective inner cover 3 slipping off is avoided.
