Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an assembled high and low voltage power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits; the motor control center is used for occasions with concentrated loads and more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This set of equipment should provide protection, monitoring and control for the load.

[0003] The size of existing distribution cabinets is fixed at the factory, which makes them inappropriate for some unconventional locations. If they are too large, it will waste space, and if they are too small, electrical components cannot be installed inside. At the same time, since the space inside the distribution cabinet is relatively small, it needs to be dismantled when the internal equipment is inspected and repaired, which is extremely time-consuming.

[0025] In a preferred embodiment, the fixing assembly 6 includes a square groove 601, the inner wall of the square groove 601 is provided with a built-in square groove 606, the inner wall of the square groove 601 is fixedly installed with a fixed semi-cylinder 604, the outer wall of the fixed semi-cylinder 604 is slidably sleeved with a collar 605, the inner wall of the built-in square groove 606 is provided with a spring 2 602, and the inner wall of the built-in square groove 606 is slidably connected with a pressure block 603. In the above structure, the bottom outer wall of the collar 605 is provided with an angled surface, and the upper and lower corners of the pressure block 603 close to the collar 605 are provided. There is an angled surface. By putting the ring 605 on the outside of the fixed semi-cylinder 604, it is pressed toward the inside of the square groove 601, and the pressing block 603 is pushed to both sides through the angled surface of the ring 605, so that the pressing block 603 moves toward the inside of the built-in square groove 606, thereby causing the spring 2 602 to contract. When the ring 605 and the square groove 601 are added together, the elasticity of the spring 2 602 pushes the pressing block 603 out to overlap with the side of the ring 605 away from the square groove 601, thereby causing the ring 605 to be fixed by the pressing block 603.

[0026] In a preferred embodiment, the square groove 601 is located at the junction of the fixed box 2 and the installation box 4, and the upper and lower sides of the square groove 601 are symmetrically arranged on both sides of the junction of the fixed box 2 and the installation box 4. In the above structure, the fixed semi-cylinder 604 at the junction of the fixed box 2 and the installation box 4 is fixed by the pressing block 603, so that the ring 605 connects the fixed box 2 and the installation box 4.

[0027] In a preferred embodiment, the number of spring 2 602, pressure block 603, fixed semi-cylinder 604 and built-in square groove 606 is two, and the two springs 2 602, pressure blocks 603, fixed semi-cylinder 604 and built-in square groove 606 are symmetrically distributed on the upper and lower sides of the square groove 601. In the above structure, the top of the ring 605 is fixed by two pressure blocks 603, so that the ring 605 is not easy to separate from the fixed semi-cylinder 604, thereby increasing stability.

[0028] In a preferred embodiment, the number of fixed semi-cylinders 604 is two, and the two fixed semi-cylinders 604 are respectively placed on both sides of the fixed box 2 and the installation box 4 inside the square groove 601, the two fixed semi-cylinders 604 are fitted together, and the diameter of the ring 605 is the same as the diameter of the two fixed semi-cylinders 604. In the above structure, by fitting the two fixed semi-cylinders 604 together and sleeved on the outer walls of the two fixed semi-cylinders 604, the two rings 605 fix the two fixed semi-cylinders 604, thereby fixing the fixed box 2 and the installation box 4.

[0029] In a preferred embodiment, the number of fixing components 6 is four, and the four fixing components 6 are respectively arranged at the junctions on both sides of the fixing box 2 and the additional box 4 and the top cover box 5. In the above structure, the fixing box 2 is fixed at the junction with the additional box 4 and the top cover box 5 by the fixing components 6 on both sides, so that the fixing box 2 is fixed to the additional box 4 and the top cover box 5.

[0030] In a preferred embodiment, a circular groove is provided on the outer wall of the fixing frame 7, and the diameter of the circular groove is the same as the diameter of the lock column 11. The circular groove provided on the outer wall of the fixing frame 7 penetrates the fixing frame 7 and reaches the inside of the sliding plate 8. In the above structure, the pull rod 12 is pulled, and the pull rod 12 drives the lock column 11 to move, so that the spring 13 contracts. When the lock column 11 completely enters the inner wall of the installation box 4, the fixed relationship between the sliding plate 8 and the fixing frame 7 disappears. At this time, the sliding plate 8 is pulled in the direction of the closing door 3, so that the sliding plate 8 reaches the outside of the installation box 4, and then the equipment above the sliding plate 8 moves to the outside of the installation box 4.

[0031] Working principle: when in use, place the base 1 and the fixed box 2 on the ground, place the additional box 4 on the top of the fixed box 2, and align the closed door 3 so that the circular column at the bottom of the closed door 3 above is inserted into the circular groove on the top of the closed door 3 below, thereby fixing the closed door 3. At this time, take out the ring 605, and put the ring 605 on the outside of the fixed semi-cylinder 604 to press it toward the inside of the square groove 601. The beveled surface of the ring 605 pushes the pressing block 603 to both sides, so that the pressing block 603 moves toward the inside of the built-in square groove 606, thereby causing the spring 2 602 to contract. When the ring 605 is added to the square groove 601, the elasticity of the spring 2 602 pushes the pressing block 603 out to overlap with the side of the ring 605 away from the square groove 601, thereby causing the ring 605 to be fixed by the pressing block 603, so that the pressing block 60 3 Fix the two fixed semi-cylinders 604, fix the fixed box 2 and the additional box 4, and complete the installation of the additional box 4 after fixing the fixed component 6 on the other side, place the top cover box 5 on the top of the additional box 4, fix the fixed component 6 between the top cover box 5 and the fixed box 2, and complete the installation of the top cover box 5. The overall size of the equipment is controlled by increasing or reducing the installation of the fixed box 2. When it is necessary to inspect the electrical components inside the equipment, pull the pull rod 12, and the pull rod 12 drives the lock column 11 to move, so that the spring 13 contracts. When the lock column 11 completely enters the inner wall of the additional box 4, the fixing relationship between the sliding plate 8 and the fixed frame 7 disappears. At this time, pull the sliding plate 8 in the direction of the closing door 3, so that the sliding plate 8 reaches the outside of the additional box 4, and then the equipment above the sliding plate 8 is moved to the outside of the additional box 4 for inspection.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
