Furthermore, if the key is lost during structural maintenance, the difficulty of maintenance is increased, resulting in insufficient applicability. Therefore, there is a need to provide a low-voltage distribution control cabinet enclosure structure that can solve the above-mentioned drawbacks and improve efficiency. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this utility model is an outer shell structure of a low-voltage distribution control cabinet, comprising:

[0025] The outer shell module includes a main frame 11 and a docking block 16. Side plates 12 are symmetrically arranged on both sides of the main frame 11. The docking block 16 is symmetrically fixed to the rear end of the inner wall of the main frame 11, and the outer side of the docking block 16 fits against the rear part of the inner side of the side plate 12. The rear end of the side plate 12 is provided with a positioning hole 17 extending into the docking block 16. A positioning post 18 is threadedly connected to the middle of the positioning hole 17. A nut 19 is threadedly connected to the outer surface of the positioning post 18 and abuts against the side plate 12.

[0026] Positioning pin 18 is inserted into positioning hole 17 and the side plate 12 is fixed by contact between nut 19 and side plate 12. That is, the side plate 12 is connected and installed to the main frame 11 to form the shell of the entire low voltage distribution switch cabinet. The modular design allows for disassembly, inspection and maintenance of independently damaged structures, thus saving costs.

[0027] A support 13 is connected through the middle of the side plate 12, and the inner wall of the support 13 is fixedly connected with shelves 14 at equal intervals, with gaps between the connected shelves 14.

[0028] The bracket 13 is installed and fixed to the shelf 14, and the gap between the connected shelf 14 meets the heat dissipation requirements of the shell.

[0029] The main frame 11 has a reinforcing block 15 threadedly connected to the middle of the upper and lower ends, and the bottom of the lower reinforcing block 15 is provided with anti-slip texture at equal intervals.

[0030] The reinforcing block 15 strengthens the upper and lower ends of the shell to reduce the probability of damage to the shell, extend its service life, save costs, and increase contact friction through anti-slip texture to ensure the stability of the shell structure.

[0031] It also includes a connection module, which includes a connection groove 21. The connection groove 21 is symmetrically opened in the middle of both sides of the reinforcing block 15. The middle of the inner wall of the upper connection groove 21 and the end of the inner wall of the lower connection groove 21 are connected to a locking block 22. A sleeve post 23 is sleeved on the middle of the outer side of the locking block 22.

[0032] The connecting groove 21 is engaged with the locking block 22, and the locking block 22 is used to fix the sleeve post 23. The sleeve post 23 can be used to install and fix the hole block 31 and the alarm 41 structure.

[0033] It also includes a moving module, which includes a hole block 31. The hole block 31 is sleeved on the outside of the lower sleeve post 23, and a bearing seat 32 passes through the middle of the hole block 31. A support column 33 is sleeved in the middle of the bearing seat 32, and a moving wheel 34 is fixedly connected to the bottom end of the support column 33.

[0034] The hole block 31 is fixed to the moving wheel 34 by means of the bearing 32 and the support column 33. The rotation of the bearing 32 can satisfy the multi-directional adjustment of the moving wheel 34, so that the low-voltage distribution cabinet can be moved by the rolling of the moving wheel 34 with the ground.

[0035] Working principle: When assembling the low-voltage distribution switch cabinet, the side plate 12 is L-shaped. A columnar protrusion is provided at one end of the straight edge of the side plate 12. At this time, the columnar protrusion can be extended into the corresponding opening in the inner wall of the main frame 11 to ensure the initial stability of the side plate 12 structure. In this state, the bent edge of the side plate 12 fits against the outer side of the mating block 16. Then, the positioning pin 18 is inserted into the positioning hole 17, and the nut 19 is tightened and abuts against the side plate 12, that is, the main frame 11 and the side plate 12 are mated and installed. In the middle of the side plate 12, the shelf 14 is equidistantly connected by the bracket 13. There is a gap between the connected shelf 14 to meet the heat dissipation inside the shell. Reverse operation can be applied during subsequent inspection and maintenance.

[0036] This solution offers several advantages. First, in the event of subsequent structural damage, the damaged independent structure can be directly disassembled for replacement or repair, effectively reducing costs. Second, even if the key is lost and the internal structure of the low-voltage distribution cabinet cannot be inspected or maintained, a side panel 12 structure can be directly disassembled to complete the inspection and maintenance of the structure, improving its applicability and functionality, meeting various needs, and facilitating use.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The anti-theft module includes an alarm 41 and an opening 42. The alarm 41 is sleeved on the outside of the upper sleeve post 23, and the opening 42 is opened on the inside of the positioning hole 17. One end of the inner wall of the opening 42 is embedded with a pressure sensor 43. A movable rope 44 is attached to one side of the pressure sensor 43, and one end of the movable rope 44 is attached to one end of the positioning post 18.

[0039] The pressure sensor 43 has a built-in control terminal that is wirelessly connected to the alarm 41.

[0040] The opening 42 accommodates the installation of the pressure sensor 43 and the storage of the movable rope 44. By means of the connection between the end of the movable rope 44 and the pressure sensor 43 and the positioning post 18, the movable rope 44 can be activated to act on the pressure sensor 43 when the positioning post 18 is disassembled and removed. This will then trigger the alarm 41 to generate an alarm for early warning, thus providing anti-theft protection. The pressure sensor 43 is model DPS310.

[0041] Working principle: During the disassembly of the side plate 12, the positioning post 18 needs to be disassembled to remove it from the positioning hole 17. When the positioning post 18 is removed from the positioning hole 17, the linkage movable rope 44 acts on the pressure sensor 43. The pressure sensor 43, after being stressed, then links the controlled alarm 41 to generate an alarm sound to achieve early warning.

[0042] This solution can provide early warning and anti-theft protection, thereby reducing the probability of loss of the internal structure of the power distribution cabinet and further saving costs.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
