[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses a power distribution device for rail transit. (Refer to...) Figure 1-3A power distribution device for rail transit includes a housing 1, a metal frame 5, and a movable plate 6. A guide rod 2 is fixedly connected to the inner wall of the housing 1. The metal frame 5 is movably installed inside the guide rod 2. Wheels 9 are fixedly connected to both sides of the bottom of the metal frame 5. Sliding frames 3 are fixedly connected to both sides of the metal frame 5, and the sliding frames 3 are fitted into the guide rod 2. A movable plate 6 is movably installed inside the metal frame 5. A limit rod 12 is fixedly connected to the inner wall of the metal frame 5 at one end of the movable plate 6, and the movable plate 6 is fitted into the limit rod 12. A magnetic block 4 is fixedly connected to one side of the movable plate 6, and the magnetic block 4 is fitted into the metal frame 5. An installation component 8 is fixedly connected to the surface of the movable plate 6. Workers install and fix the rail transit power distribution components onto the installation component 8. The housing 1 protects the power distribution components. Workers can then... Multiple sets of power distribution components are installed on three movable plates 6. When maintenance of the power distribution components is required, the movable plates 6 are pulled, causing the metal frame 5 to move to the front until the metal frame 5 is located at the front of the box 1. At this time, the staff pulls the movable plates 6 to the right, causing the magnetic block 4 attached to the metal frame 5 to separate, and the power distribution components are presented in front of the staff. The power distribution components can then be maintained. After maintenance, the movable plates 6 and the metal frame 5 can be pushed back to their original positions. There is no need to use tools to disassemble the power distribution components, which makes it easier for staff to perform maintenance operations. The guide rod 2 and the sliding frame 3 can guide and limit the movement direction of the metal frame 5, improving the stability of the movement of the metal frame 5. The wheels 9 reduce the contact area and friction between the metal frame 5 and the ground, and also eliminate the need for staff to pull out the metal frame 5.

[0019] Reference Figure 1 The bottom of the movable plate 6 is fixedly connected to a limiting block 601, and the limiting block 601 is fitted into the metal frame 5. The limiting block 601 can guide and limit the movement direction of the movable plate 6, thereby improving the stability of the movement of the movable plate 6.

[0020] Reference Figure 2 A protective door 11 is movably installed at one end of the housing 1, and a door lock 1101 is fixedly connected to the surface of the protective door 11. The protective door 11 can form protection at the front end of the housing 1, and the door lock 1101 can lock the protective door 11.

[0021] Reference Figure 1 A limiting plate 10 is fixedly connected to the bottom wall of the box 1, and the wheel 9 is fitted with the limiting plate 10. The limiting plate 10 can guide and limit the movement direction of the wheel 9, thereby improving the stability of the metal frame 5.

The operator can install multiple sets of power distribution components on three movable plates 6 respectively. When the power distribution components need to be maintained, the movable plate 6 is pulled to move the metal frame 5 to the front end until the metal frame 5 is located at the front end of the housing 1. At this time, the operator pulls the movable plate 6 to the right to separate the magnetic block 4 that is adsorbed and connected to the metal frame 5, and the power distribution components are presented in front of the operator, who can then perform maintenance on the power distribution components. The guide rod 2 and the sliding frame 3 guide and limit the movement direction of the metal frame 5. The wheel 9 reduces the contact area and friction between the metal frame 5 and the ground, ensuring the smooth movement of the metal frame 5.
