[0026] Reference Figure 1-5 As shown, the present application provides a technical solution: a power distribution cabinet that is easy to maintain, comprising a cabinet body and a cabinet cover, two cabinet doors are installed on the surface of the cabinet body, a plurality of heat dissipation holes are opened on the side wall of the cabinet body, a supporting device is provided on the inner wall of the cabinet body, and a buffer device is provided on the surface of the cabinet cover.

[0027] The specific settings and functions of the supporting device and the buffer device are described in detail below.

[0028] Reference Figure 2 and Figure 3 As shown, in this embodiment: the support device includes four support columns, which are slidably connected to the inner wall of the cabinet, and the upper end of the support column is fixedly connected to the cabinet cover. The side wall of the cabinet is fixedly connected to a cylindrical block, and the surface of the cylindrical block is fixedly connected to a square tube. A push rod is slidably penetrated through the inner wall of the square tube, and the arc surface of the push rod is provided with two plug holes. The side wall of the square tube is slidably penetrated by a plug rod, and the size of the plug rod is adapted to the size of the plug hole. A circular plate is fixedly connected to one side of the plug rod, and a spring is sleeved on the arc surface of the plug rod. The two ends of the spring are respectively fixedly connected to the circular plate and the square tube. When the spring contracts, the circular plate will drive the plug rod to be inserted into the plug hole located below with the help of the tension of the spring, and the spring achieves the effect of automatically resetting the plug rod. A limit ring is fixedly connected to the arc surface of the push rod, and a positioning plate is fixedly connected to the lower end of the push rod. During the sliding process of the push rod, the limit ring and the positioning plate can prevent the push rod from falling off from the square tube.

[0029] Reference Figure 4 and Figure 5As shown, specifically, the buffer device includes four limit frames, the limit frames are fixedly connected to the cabinet cover, the surface of the limit frames is threadedly connected with bolts, the upper ends of the bolts are rotatably connected to the limit plates, the surface of the limit plates is slidably connected with shock-absorbing pads, the shock-absorbing pads are slidably connected to the cabinet cover, and the shock-absorbing pads are rubber pads. A square plate is fixedly connected to one side of the limit plate, the surface of the square plate slides through the limit column, the cabinet cover is fixedly connected to the limit column, the movement of the limit plate will drive the square plate to slide along the arc surface of the limit column, the limit column can limit the sliding path of the square plate, thereby limiting the movement path of the limit plate, the surface of the limit plate is slidably connected with a plurality of limit gaskets, the limit gaskets are slidably connected to the shock-absorbing pads, the movement of the limit plate will cause the limit gaskets to contact with the shock-absorbing pads, and the limit gaskets can increase the friction between the limit plate and the shock-absorbing pads.

[0030] Working principle: when it is necessary to inspect the electrical equipment in the cabinet from different angles and positions, first open the cabinet door, then pull the round plate, the sliding of the round plate will drive the plug rod to slide out from the inner wall of the socket, the sliding of the round plate will also stretch the spring, at this time the spring is in a stretched state, then lift the cabinet cover and the top rod upwards, the sliding of the cabinet cover will drive the support column to slide along the inner wall of the cabinet, the support column can limit the sliding path of the cabinet cover, when another socket on the top rod is aligned with the plug rod, the spring begins to contract, the round plate will use the tension of the spring to drive the plug rod to insert into the socket below, the plug rod reaches the position to limit the top rod, from The function of limiting the position of the cabinet cover is that the maintenance personnel can inspect the electrical equipment in the cabinet through the gap between the cabinet door or the cabinet cover and the cabinet body, which greatly facilitates the operation of the maintenance personnel. After the inspection is completed, the round plate is pulled again to disengage the plug rod from the socket. At this time, the cabinet cover can be slid downward to reset the cabinet cover. During the sliding process of the top rod, the limit ring and the positioning piece can prevent the top rod from falling off the square tube. By setting the supporting device, when inspecting the electrical equipment in the cabinet, the operation can be performed from different positions and directions, which makes it convenient for the maintenance personnel to inspect the electrical equipment.

[0031] When the buffer device is needed, the shock-absorbing pad is placed between the limit plate and the cabinet cover, and then the bolt is turned. The bolt will drive the limit plate to move upward with the help of the thread. The movement of the limit plate will drive the square plate to slide along the arc surface of the limit column. The limit column limits the sliding path of the square plate, thereby limiting the moving path of the limit plate. The movement of the limit plate will cause the limit gasket to contact the shock-absorbing pad. The limit gasket increases the friction between the limit plate and the shock-absorbing pad. The limit plate limits the position of the shock-absorbing pad. When the cabinet cover moves downward, the shock-absorbing pad will contact the cabinet body. At this time, the shock-absorbing pad will reduce the collision force between the cabinet cover and the cabinet body, thereby preventing the cabinet cover from being deformed by impact. By setting the buffer device, when the cabinet cover is put back to its original position after the inspection is completed, the collision force between the cabinet cover and the cabinet body can be reduced, thereby preventing the cabinet cover from being deformed by impact, thereby greatly extending the service life of the cabinet cover.
