Description

Technical Field

[0001] This utility model relates to the field of power switchgear technology, and in particular to a prefabricated power switchgear. Background Technology

[0002] Prefabricated power switchgear is used due to its advantages such as convenient delivery and easy disassembly and reassembly. However, prefabricated power switchgear still has some defects and shortcomings in use, specifically the following areas needing improvement: 1. The internal terminal blocks require drilling holes and screws for fixing during use, and re-drilling is also required when changing positions, increasing the difficulty of fixing the terminal blocks and making it inconvenient to change positions; 2. During the use of the power cabinet, slight vibrations can cause the wiring joints to slip and become inconvenient. Therefore, we propose a prefabricated power switchgear. Utility Model Content

[0003] The main objective of this invention is to provide a prefabricated power switchgear that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A prefabricated power switchgear includes a cabinet shell, with a front door movably connected to the upper and lower front ends of the cabinet shell via hinges, a support mechanism fixedly connected to the lower left and lower right ends of the cabinet shell, a drawer box inserted in the middle of the cabinet shell, and a connecting mechanism fixedly connected to the rear upper and lower inner walls of the cabinet shell.

[0006] Preferably, the connecting mechanism includes two sets of mounting frames and several sets of connecting plates. The left and right ends of the two sets of mounting frames are each provided with several sets of through holes at equal intervals. The front ends of the several sets of connecting plates are each fixedly connected with several sets of wiring pipes at equal intervals. The left and right ends of the several sets of connecting plates are each fixedly connected with an extension plate. The far end of the several sets of extension plates is provided with a set of through holes. The inner walls of the through holes on the several sets of extension plates are each fixedly connected with a No. 1 spring. The No. 1 spring is fixedly connected with a snap-fit ​​rod.

[0007] By adopting the above technical solution, both the extension plate and the connecting plate are made of insulating material, which can prevent electric shock during subsequent use.

[0008] Preferably, both sets of mounting frames are fixedly connected to the inner wall of the assembly cabinet shell, and the extension plate is snapped into the inside of the mounting frame.

[0009] By adopting the above technical solution, the two sets of mounting frames together restrict the connecting plate.

[0010] Preferably, the snap-fit ​​rod is snapped into the through hole on the mounting frame.

[0011] By adopting the above technical solution, the connecting plate can be fixed by interlocking the snap-fit ​​rod with the through hole.

[0012] Preferably, the support mechanism includes two sets of support rods, front and rear. The lower ends of the two sets of support rods are fixedly connected to a No. 1 plate. The left and right sides of the far ends of the two sets of support rods are fixedly connected to side support rods. Fixing bolts are inserted at the front and lower ends of the No. 1 plate. A No. 2 plate is inserted at the lower part of the two sets of fixing bolts. A No. 2 spring is fixedly connected at the front and rear of the No. 1 plate and the No. 2 plate. Several sets of buffer strips are fixedly connected at equal distances at the lower end of the No. 1 plate and the upper end of the No. 2 plate.

[0013] By adopting the above technical solution: the buffer strip is made of rubber, and the surface of the second spring has a specific anti-corrosion coating.

[0014] Preferably, the upper ends of the support rod and the side support rod are fixedly connected to the lower end of the assembly cabinet shell, and the fixing bolt passes through the nearby No. 2 spring.

[0015] By adopting the above technical solution, both the No. 2 spring and the buffer bar are in a compressed state, which can absorb the vibration of the upper part and reduce the vibration.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up a connecting mechanism, the snap-fit ​​rod on the extension plate of the connecting mechanism is snapped into the through round hole on the mounting frame for fixation. The fixing method is simple, does not require drilling or screw fixing, and also facilitates the adjustment of the position of the connecting plate.

[0018] 2. By setting up a support mechanism, the buffer strip and the second spring between the first and second plates on the support mechanism are compressed, requiring greater force to generate vibration, thereby reducing vibration during use and preventing the wiring from vibrating and falling off.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A prefabricated power switchgear includes a cabinet shell 1. The upper and lower front parts of the cabinet shell 1 are movably connected to a front door 2 via hinges. The lower left and lower right parts of the cabinet shell 1 are fixedly connected to a support mechanism 3. A drawer box 4 is inserted in the middle of the cabinet shell 1. The upper and lower inner rear parts of the cabinet shell 1 are fixedly connected to a connecting mechanism 5.

[0029] In this embodiment, the connecting mechanism 5 includes two sets of mounting frames 6 and several sets of connecting plates 7. Several sets of through holes 8 are equally spaced at the left and right ends of the two sets of mounting frames 6. Several sets of wiring pipes 9 are fixedly connected at equal distances at the front ends of the several sets of connecting plates 7. Extension plates 10 are fixedly connected at the left and right ends of the several sets of connecting plates 7. A set of through holes 8 is opened at the far end of the several sets of extension plates 10. A No. 1 spring 11 is fixedly connected to the inner wall of the through holes 8 on the several sets of extension plates 10. A snap-fit ​​rod 12 is fixedly connected to the several sets of No. 1 springs 11. The two sets of mounting frames 6 are fixedly connected to the inner wall of the assembly cabinet shell 1. The extension plates 10 are snapped into the inside of the mounting frames 6. The snap-fit ​​rod 12 is inserted and snapped into the through holes 8 on the mounting frames 6.

[0030] With the above solution: the snap-fit ​​rod 12, which is fixedly connected to the extension plate 10 on the connecting mechanism 5 by the No. 1 spring 11, is inserted and snapped into the through round hole 8 on the mounting frame 6, which can fix the position of the connecting plate 7, making it convenient to replace and fix the connecting plate 7 without drilling holes or using screws.

[0031] In this embodiment, the support mechanism 3 includes two sets of support rods 13, one at the front and one at the back. The lower ends of the two sets of support rods 13 are fixedly connected to a No. 1 plate 14. The left and right ends of the two sets of support rods 13 are fixedly connected to side support rods 15. Fixing bolts 16 are inserted at the front and lower ends of the No. 1 plate 14. The lower parts of the two sets of fixing bolts 16 are inserted to form a No. 2 plate 17. A No. 2 spring 18 is fixedly connected at the front and rear of the No. 1 plate 14 and the No. 2 plate 17. Several sets of buffer strips 19 are fixedly connected at equal distances at the lower end of the No. 1 plate 14 and the upper end of the No. 2 plate 17. The upper ends of the support rods 13 and the side support rods 15 are fixedly connected to the lower end of the assembly cabinet shell 1. The fixing bolts 16 pass through the adjacent No. 2 spring 18.

[0032] With the above solution, a buffer strip 19 and a compressed second spring 18 are provided between the first plate 14 and the second plate 17 on the support mechanism 3, which can increase the ability to accept external forces, offset some of the upper vibration, and reduce the disconnection at the wiring point.

[0033] It should be noted that this utility model is a prefabricated power switch cabinet. During use, the fixing bolt 16 is first passed through the first plate 14 and the second plate 17. Rotating the fixing bolt 16 reduces the gap between the first plate 14 and the second plate 17, and at the same time, the internal buffer strip 19 and the two sets of second springs 18 are compressed together, making the buffer strip 19 and the second springs 18 more capable of receiving external forces, which can offset the impact of vibration and reduce the slippage of wires at the upper wiring point. At the same time, the side support rod 15 and the support rod 13 can increase the fixed connection with the cabinet shell 1. After installation and fixing, after opening the front door 2, the snap-fit ​​rod 12 connected by the first spring 11 on the extension plate 10 is compressed inward. Then, the two sets of extension plates 10 are passed through the interior of the left and right mounting frames 6, which can be used to place the connecting plate 7. Under the action of the first spring 11, the snap-fit ​​rod 12 is inserted and snapped into the through round hole 8 on the mounting frame 6, which can fix the position of the connecting plate 7. The operation is simple and it is also convenient to change the position of the connecting plate 7 for easy wiring. No drilling or screw fixing is required.
