Description

Technical Field

[0001] This disclosure specifically discloses a technical field of electrical box technology, specifically relating to an electrical box with drop compensation. Background Technology

[0002] Refrigeration equipment is widely used in various industries, but as customers' demands for electrification, intelligence, and maintainability continue to increase, the size and weight of electrical boxes have become a prominent issue. To improve maintainability, hinges are typically used to mount electrical boxes, allowing for rotation and increasing the maintenance area. However, due to the electrical box's center of gravity and weight, simply using hinges can lead to deformation and sagging. During maintenance, rotating the electrical box may result in scraping, difficulty in rotation, or obstruction, which is detrimental to equipment maintenance. Therefore, we propose an electrical box with sagging compensation. Summary of the Invention

[0021] As mentioned in the background section, existing technologies, due to the influence of the electrical box's center of gravity and weight, often result in deformation and sagging when using only hinges for installation. During maintenance, rotating the electrical box may cause scratches, difficulty in rotation, or obstruction, which is detrimental to equipment maintenance. This disclosure proposes a structure with telescopic supports.

[0022] Example 1

[0023] Please see Figure 1 An electrical box with fall compensation includes an electrical box body 1, the electrical box body 1 having a first chamber for housing the electrical box; two boxes 2 are provided on one side of the electrical box body 1 along a first direction, which in this embodiment is a horizontal direction; the two boxes 2 are rotatably connected to the corresponding side walls of the electrical box body 1 on opposite sides; in this embodiment, the opposite sides of the two boxes 2 are connected to the inner wall of the electrical box body 1 by hinges to ensure that the boxes 2 can swing normally; due to the weight of the boxes, the boxes may fall, so anti-fall devices are fixedly connected to the bottom of the two boxes 2 at their near ends, the anti-fall devices are used to prevent the boxes from falling, the anti-fall devices extend along a second direction, which in this embodiment is a vertical direction; the anti-fall devices ensure that both boxes 2 can open and close normally.

[0024] Please see Figure 2To further support the two door 2 and prevent them from falling, support devices 5 are respectively provided on the sides of the two door 2 near the first chamber. The other end of the support device 5 is connected to the side wall of the electrical box body 1. That is, one end of the support device 5 is connected to the door 2, and the other end is connected to the side wall of the electrical box body 1 near the door 2. The connection through the support device 5 has a restraining effect on both door 2 and prevents the door 2 from falling.

[0025] Please see Figure 2 To support the door 2 and ensure it has a certain anti-fall function, a support device 5 is formed by connecting seat 51, connecting piece 52, and telescopic rod 53. To ensure the stability of the upper part of the door 2, the support device 5 is set on the upper part of the door 2. A connecting seat 51 is provided on the side of the door 2 near the first chamber, and a connecting seat 51 is also fixedly connected to the corresponding side wall of the electrical box body 1. Connecting pieces 52 are movably connected to the inner cavity of the connecting seat 51. The connecting seat 51 on the end face of the door 2 and the connecting seat 51 on the side wall of the electrical box body 1 are at the same horizontal plane, and a telescopic rod 53 is fixedly connected between the two connecting pieces 52. The telescopic rod 53 restrains the door 2 and effectively prevents the door 2 from falling.

[0026] Please see Figure 3 To ensure support for the door 2 and smooth opening and closing, and to accommodate uneven bases, an anti-fall device is constructed using a fixed plate 6, a sleeve 7, a telescopic column 8, a spring 9, a support rod 10, a bearing 11, a fixed base 12, and rollers 13. A fixed plate 6 is fixedly connected to the bottom of the door 2. A sleeve 7 is fixedly connected to the end face of the fixed plate 6 away from the door 2. A telescopic column 8 is fixedly connected to the inner cavity of the sleeve 7 near the fixed plate 6. A support rod 10 is fixedly connected to the end face of the telescopic column 8 away from the fixed plate 6. For the support rod 10 to facilitate its extension and retraction, a spring 9 is fitted on the outside of the telescopic column 8. One end of the spring 9 is fixedly connected to the end face of the inner cavity of the sleeve 7 near the fixed plate 6, and the other end of the spring 9 is fixedly connected to the support rod 10. A bearing 11 is fixedly connected to the end face of the support rod 10 away from the telescopic column 8. The bearing 11 ensures that the roller 13 can rotate 360° on the same horizontal plane. A fixed seat 12 is fixedly connected to the lower end face of the outer ring of the bearing 11, and the roller 13 is movably connected to the inner cavity of the fixed seat 12.

[0027] Please see Figure 3 To ensure the stability of the support rod 10, the support rod 10 is matched with the sleeve 7, and the length of the telescopic column 8 is less than the length of the sleeve 7, which effectively ensures the stability of the support rod 10 and ensures that the support rod 10 can extend and retract within the cavity of the sleeve 7.

[0028] Please see Figure 1To facilitate opening and closing of the door 2, a handle 3 is fixedly connected to the middle of the side of the door 2 away from the first cavity, and a rubber sleeve is fitted over the handle 3.

[0029] Example 2

[0030] Please see Figure 1 In order to effectively prevent moisture from remaining on the upper part of the electrical box body 1, a rain shelter 4 is provided on the top of the electrical box body 1, and the rain shelter 4 has a ridge structure to facilitate the outflow of rainwater.

[0031] Working principle: When in use, during maintenance of the door 2, the staff can use the handle 3 to open the door 2. As the door 2 opens, the anti-fall device moves. When the base of the electrical box body 1 is uneven, the telescopic column 8 extends and retracts, causing the spring 9 to retract and the support rod 10 to retract into the inner cavity of the sleeve 7, ensuring that the roller 13 rolls normally on the base. Through the cooperation of the roller 13, the support rod 10 and the sleeve 7, the door 2 can be supported. At the same time, through the cooperation of the connector 52 and the telescopic rod 53, the telescopic rod 53 effectively restrains the door 2 and effectively prevents the door 2 from falling.
