Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a distribution box that is easy to maintain. Background Technology

[0002] A distribution box is a low-voltage power distribution device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Distribution boxes can rationally distribute electrical energy, facilitate circuit opening and closing operations, have a high level of safety protection, and can intuitively display the circuit's continuity status. They are easy to manage and facilitate maintenance in case of circuit faults. During normal operation, circuits can be connected or disconnected manually or automatically; in case of faults or abnormal operation, protective electrical appliances can cut off the circuit or issue an alarm. Distribution boxes can display various parameters of their operation using measuring instruments, and can also adjust certain electrical parameters. They can also provide alerts or signals for deviations from normal operating conditions. They are commonly used in power generation, distribution, and substations. When in use, electronic components are generally mounted on a mounting plate inside the distribution box.

[0003] Chinese Patent No. CN220673160U discloses a power distribution box that is easy to maintain. The box includes a housing with a mounting bracket fixedly connected to its inner wall. Electronic components are mounted on the front end of the mounting bracket. Slide grooves are formed on both the upper and lower side walls of the housing, and sliding plates are slidably connected between the inner walls of the slide grooves. A lifting assembly is provided between the two sliding plates. A door panel is provided on the front side of the housing, with a limiting assembly at the outer end of the door panel. A hinge is installed between the door panel and the housing, and a groove is formed at the outer end of the door panel. A handle is fixedly connected between the inner walls of the groove. During the maintenance of the electronic components installed inside the power distribution box, the lifting assembly allows workers to fix lighting or maintenance tools, facilitating the maintenance of electronic components in different locations within the box and improving maintenance efficiency.

[0004] However, in actual use, when it is necessary to repair the electrical components inside the distribution box, the two sides of the electrical components are blocked by the side panels of the box, which makes it very inconvenient for the operator to carry out the repair.

[0005] Therefore, a distribution box that is easy to inspect and maintain is proposed. Utility Model Content

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Please refer to Figures 1 to 7 As shown, an embodiment of this utility model provides a distribution box that is easy to maintain, including a distribution box body 1. One side of the distribution box body 1 is open. A door 2 is hinged to the opening of the distribution box body 1. An installation plate 4 for installing electrical components is installed inside the distribution box body 1 through a telescopic mechanism 3. The telescopic mechanism 3 can drive the installation plate 4 to extend from the opening of the distribution box body 1 to the outside of the distribution box body 1.

[0031] In this embodiment, the telescopic mechanism 3 includes two sets of telescopic components. Each set of telescopic components includes a scissor structure 301, a first mounting base 302, and a second mounting base 303. The scissor structure 301 is disposed between the first mounting base 302 and the second mounting base 303. The upper two ends of the scissor structure 301 are hinged to the upper ends of the first mounting base 302 and the second mounting base 303, respectively. The lower two ends of the scissor structure 301 are slidably connected to the lower ends of the first mounting base 302 and the second mounting base 303, respectively. The mounting plate 4 is fixedly installed on the first mounting base 302. A mounting base 302 is located away from the side of the scissor structure 301. A second mounting base 303 is fixedly installed on the inner wall of one side of the distribution box 1. The two scissor structures 301 are connected by a connecting rod at the lower side of the end near the second mounting base 303. A drive mechanism for driving the extension of the scissor structure 301 is fixedly installed inside the distribution box 1. The drive mechanism includes a gas spring support rod 304. The bottom of the gas spring support rod 304 is fixedly installed on the inner wall of one side of the distribution box 1 by a fixing seat 305. The upper end of the piston rod of the gas spring support rod 304 is fixedly connected to the connecting rod.

[0032] To prevent the mounting plate 4 from being easily pushed out of the distribution box 1, a locking block 401 is hinged to the lower end of the side of the mounting plate 4 away from the telescopic mechanism 3 to limit the mounting plate 4 inside the distribution box 1. An arc-shaped groove 105 is provided at the bottom inner side of the distribution box 1. The lower end of the locking block 401 can be screwed into the arc-shaped groove 105. A slot 106 is provided at the bottom inner side of the distribution box 1. The slot 106 is connected to the arc-shaped groove 105. The slot 106 is located on the side of the arc-shaped groove 105 away from the mounting plate 4. After the locking block 401 is screwed into the arc-shaped groove 105, it can be locked into the slot 106.

[0033] By adopting the above-mentioned technical solution for easy maintenance of the distribution box, when in use, the electrical components are installed on the mounting plate 4, and then the mounting plate 4 is pushed towards the inside of the distribution box 1. At this time, the scissor structure 301 gradually folds after being squeezed, and the piston rod of the gas spring support rod 304 retracts. When the mounting plate 4 is completely moved into the inside of the distribution box 1, the locking block 401 is rotated, and the lower end of the locking block 401 is screwed into the arc groove 105. Then the mounting plate 4 is released. At this time, the scissor structure 301 will be subjected to the elastic force of the gas spring support rod 304, causing the mounting plate 4 to move towards the distribution box 1, thereby locking the locking block 401 into the locking groove 106. This completes the fixing of the mounting plate 4. The locking groove 106 can effectively prevent the locking block 401 from easily rotating out of the arc groove 105.

[0034] When it is necessary to inspect the electrical components on the mounting plate 4, push the mounting plate 4 towards the inside of the distribution box 1 to pull out the locking block 401 from the locking slot 106, then rotate the locking block 401 to unscrew it from the arc groove 105, and then release the mounting plate 4. At this time, the scissor structure 301 is squeezed by the gas spring support rod 304 and gradually extends, thereby smoothly pushing the mounting plate 4 out of the distribution box 1.

[0035] To facilitate the rotation of the locking block 401, a handle 402 is fixedly connected to one side of the locking block 401.

[0036] In this embodiment, for ease of installation, mounting ears 101 are fixedly connected to both opposite sides of the distribution box 1. A wire hole 103 is provided on the back of the distribution box 1. A removable dust cover 104 is provided inside the wire hole 103. The dust cover 104 can be used to seal unused wire holes 103 to prevent external dust from entering the distribution box 1.

[0037] It should be noted that a reserved hole 401 for threading wires is provided on the mounting plate 4.

[0038] In this embodiment, in order to ensure the stable operation of the electrical components inside the distribution box 1, heat dissipation holes 102 are provided on the side of the distribution box 1.

[0039] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
