Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and more specifically, the utility model relates to a distribution cabinet which is convenient to assemble. Background Art

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the end-level equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions where the load is relatively dispersed and the number of circuits is small; the motor control center is used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load, and this level of equipment should provide protection, monitoring, and control for the load.

[0003] In the existing distribution cabinet, since each part of the cabinet body is processed and set separately, the assembly is relatively cumbersome, time-consuming and laborious, and bolts are required to fix between multiple parts. Generally, dozens of bolts need to be installed on a distribution cabinet to ensure the stability after assembly, which is also a waste. Therefore, it is very necessary to design a distribution cabinet with simpler assembly and easier operation. Content of the Utility Model

[0006] The connection mechanism includes a connecting plate arranged between the inner sides of the lower cabinet body and the upper cabinet body. Fixed plates are fixedly connected to both sides of the connecting plate near the inner walls of the lower cabinet body and the upper cabinet body, and fixing blocks for receiving the bottom edge of the upper cabinet body are connected to the outer walls of the fixed plates.

[0007] As a further improvement of the technical solution of the utility model, the fixed plate is fixedly welded to the end of the connecting plate, fastening bolts are connected between the fixed plate and the inner wall of the bottom of the upper cabinet body and the inner wall of the top of the lower cabinet body, screw holes are arranged inside the fixed plate corresponding to the connection positions of the fastening bolts, and internal threaded holes matching the positions of the screw holes are opened on the inner wall of the bottom of the upper cabinet body and the inner wall of the top of the lower cabinet body corresponding to the connection positions of the fastening bolts.

[0008] As a further improvement of the technical solution of the utility model, door panels are connected to the front ends of the lower cabinet body and the upper cabinet body through hinges.

[0009] As a further improvement of the technical solution of the present utility model, the locking mechanism includes a fixed ring fixedly connected to the bottom of the lower cabinet body. An insertion rod is inserted in the middle of the fixed ring. A toggle block is fixedly connected above the fixed ring at the top end of the insertion rod. A locking bolt for locking the position of the insertion rod is connected to the outer wall of the fixed ring. A strip-shaped groove for the insertion of the clamping rod is provided at the top of the base, and an annular cavity is communicated with the bottom of the strip-shaped groove.

[0010] As a further improvement of the technical solution of the present utility model, the fixed ring is fixedly welded between the bottom inner wall of the lower cabinet body, and a through hole for the insertion rod to pass through is provided at the bottom of the lower cabinet body.

[0011] As a further improvement of the technical solution of the present utility model, the inner diameter of the cross-section of the fixed ring is larger than the outer diameter of the cross-section of the insertion rod. An internal threaded hole for connecting the locking bolt is provided on the outer wall of the fixed ring, and the end of the locking bolt is tightly abutted against the outer wall of the insertion rod.

[0012] As a further improvement of the technical solution of the present utility model, the length and width of the cross-section of the strip-shaped groove are respectively larger than the length and width of the cross-section of the clamping rod, and the diameter of the cross-section of the annular cavity is larger than the length of the clamping rod.

[0013] The beneficial effects of the present utility model:

[0014] 1. By setting the locking mechanism, when assembling the lower cabinet body and the base, push the insertion rod downward inside the fixed ring, and make the clamping rod at the bottom of the insertion rod extend into the inside of the strip-shaped groove. After extending into the inside of the annular cavity, rotate the toggle block to drive the insertion rod and the clamping rod to rotate, so that the clamping rod deviates from the position of the strip-shaped groove, and then tighten the locking bolt. The locking mechanisms at the four positions can complete the assembly between the lower cabinet body and the base through this operation. When disassembly is required, on the contrary, first loosen the locking bolt, and then rotate the toggle block to drive the clamping rod to reset directly below the strip-shaped groove;

[0015] 2. By setting the connection mechanism, after the lower cabinet body and the base are assembled, fix the connection mechanism on the top of the lower cabinet body, make the two end plates stick to the inner wall of the lower cabinet body, and use the fastening bolts to fix the end plates to the inner wall of the lower cabinet body.
