Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a pull-out power distribution cabinet which is easy to maintain. Background Art

[0002] The pull-out power distribution cabinet is a kind of storage equipment specially used for power components, which is designed to protect circuit components outdoors.

[0003] The patent with the patent announcement number CN216959030U involves: a cabinet, and the cabinet can be connected to a device, a mounting plate is arranged inside the cabinet, one side of the mounting plate is connected to an electric device, and the electric device can provide power, and a wire hole is opened at the bottom of the cabinet. The pull-out power distribution cabinet that is easy to repair, the sliding block slides through the sliding groove when it moves, and the electric device can be inspected when the sliding block slides to one end of the sliding groove, which is convenient for rapid detection of the electric device. In this way, when the outside air enters the cabinet through the heat dissipation port, the filter layer can absorb water molecules in the air to keep the cabinet dry, which is convenient for moisture-proofing the cabinet. When the threaded rod rotates, the second threaded groove is used for threaded sliding, and the threaded rod drives the extrusion plate to move when the thread slides. When the extrusion plate moves, it squeezes the connecting wire to prevent the connecting wire from falling off.

[0004] In the above patent, when outside air enters the cabinet through the heat dissipation port, the filter layer can absorb water molecules in the air to keep the cabinet dry, making it convenient to prevent the cabinet from moisture. When the threaded rod rotates, the thread slides through the second thread groove. When the thread of the threaded rod slides, the extrusion plate is driven to move. When the extrusion plate moves, the connecting wire is squeezed to prevent the connecting wire from falling off. However, there are still some problems. When the electrical box is repaired, the drawer needs to be pulled for repair. However, when the drawer is pulled too fast, it is possible to pull the drawer out of the electrical box and damage the wires connected behind it. At the same time, it will also prevent some non-professionals from pulling it by mistake and causing danger. Summary of the invention

[0007] According to the above technical solution, a No. 1 spring is arranged inside the telescopic plate, and a No. 2 spring is arranged between the elliptical cylinder and the trapezoidal block. When the telescopic plate is stretched, the blocking piece is pulled back by the elastic force of the spring.

[0008] According to the above technical solution, the triangular stopper contacts the trapezoidal block, and the stopper rod contacts the baffle plate. The trapezoidal block will move upward due to the extrusion, and will be limited by the triangular stopper when returning.

[0010] According to the above technical solution, a No. 3 spring is arranged inside the telescopic block plate, and a No. 4 spring is arranged on the abutment plate and the telescopic block plate. When the spring rebounds, the telescopic block plate will pull the triangular card upward to release the limit.

[0011] According to the above technical solution, the teeth below the slide column mesh with the gear, the output plate fits tightly with the electrical box, and the gear will push the slide column forward.

[0014] The present invention provides a pull-out power distribution cabinet that is easy to maintain. It has the following beneficial effects: (1) In this invention, when the straight rod moves, it drives the orifice plate to move in the chamber. Since the hole above the orifice is too small, it can only be pulled out slowly. When the baffle rod falls downward, it squeezes the baffle plate, preventing the staff from pulling the drawer too quickly or too hard during work, thereby avoiding damage to the line during violent movement. It can also prevent damage caused by unplugging the plug to a limited extent, reducing the workload and difficulty of the staff.

[0015] (2) In this invention, when the straight rod moves, it drives the telescopic block plate to move away from the abutment plate. When the straight rod moves, it drives the ring column to move. When the ring column moves, it drives the gear to move. The repeated pulling and pulling by the staff can easily cause wear to the slide groove, and also reduce the working life of the electric box. This avoids the need for manual lubrication by the staff, reduces the ineffective waste of labor, and also greatly increases the life of the slide groove.

[0016] (3) In the present invention, when the column moves upward, it drives the long stick upward, and when the long stick moves upward, it drives the wide plate upward, thereby releasing the gear from continuing to push the slide column, preventing the slide column from continuing to squeeze the oil tank when the lubricating oil inside the lubricating oil storage device is completely consumed, thereby damaging the gear in front and causing inconvenience in subsequent use.
