Description

Technical Field

[0001] This utility model belongs to the field of distribution box technology, and specifically relates to a combined distribution box. Background Technology

[0002] In power systems, distribution boxes are commonly used electrical devices for distributing electrical energy and controlling circuits. Modular distribution boxes typically consist of a main distribution box and a secondary distribution box. In practical applications, these boxes need to be easy to assemble and disassemble to improve installation and maintenance efficiency. However, existing modular distribution boxes may suffer from complex operation and poor stability during assembly, and it is difficult to effectively prevent unauthorized personnel from disassembling the secondary distribution box, which could lead to circuit failures or safety hazards. Therefore, it is necessary to design a new modular distribution box to address these issues. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a modular distribution box that prevents unauthorized personnel from disassembling the secondary distribution box by removing the pull ring, thereby improving the installation efficiency and safety of the distribution box.

[0004] A modular distribution box includes a main distribution box and a pair of auxiliary distribution boxes, wherein the pair of auxiliary distribution boxes are installed on the left and right sides of the main distribution box via a convenient disassembly assembly.

[0005] The easy-to-install and disassemble assembly includes a guide block fixed to the side wall of the main distribution box and a guide block fixed to the side wall of the auxiliary distribution box, as well as a limiting mechanism provided on the guide block. The guide block has guide holes.

[0006] The limiting mechanism includes a sliding cavity formed on the guide block, with a sliding plate inside the cavity. A guide rod is fixed to one end of the sliding plate, and a guide seat is fixed to the other end. One end of the guide seat has an annular groove and an insertion hole, the annular groove communicating with the insertion hole. One end of a pull ring can be inserted into the annular groove through the insertion hole. Rotating the pull ring limits that end to the annular groove, thus connecting the pull ring to the guide seat. Reversing the rotation of the pull ring disengages it from the annular groove, disassembling the pull ring from the guide seat. In the connected state, the guide seat can be moved by pulling the pull ring.

[0007] Furthermore, the guide groove of the guide block is a dovetail groove, and the shape of the guide block is adapted to the dovetail groove to achieve a stable sliding connection between the auxiliary distribution box and the main distribution box in the horizontal direction.

[0008] Furthermore, an elastic element is provided inside the sliding cavity. One end of the elastic element abuts against the inner wall of the sliding cavity, and the other end abuts against the sliding plate. When the pull ring is not pulled by an external force, the elastic element keeps the sliding plate in its initial position.

[0009] Furthermore, the end of the guide rod is provided with a positioning head, and the inner diameter of the guide hole is adapted to the outer diameter of the positioning head. When the auxiliary distribution box and the main distribution box are installed in place, the positioning head can be inserted into the guide hole to achieve positioning.

[0010] Furthermore, the outer surface of the pull ring is provided with anti-slip texture to increase the friction when the operator holds the pull ring, making it easier to operate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Easy assembly: The auxiliary distribution box engages with the guide slot block on the main distribution box via a guide block, and the guide slot is a dovetail groove, achieving a stable horizontal sliding connection, facilitating the installation and disassembly of the auxiliary distribution box. Simultaneously, the positioning head at the end of the guide rod, in conjunction with the guide hole, enables precise positioning upon installation, further improving assembly efficiency.

[0013] To prevent unauthorized disassembly: The pull ring and guide seat are detachable, allowing the pull ring to be removed and properly stored during normal use. Without the pull ring, the limit mechanism is difficult for non-professionals to operate, effectively preventing unauthorized disassembly of the auxiliary distribution box and improving its safety.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1-9 As shown;

[0029] A modular distribution box.

[0030] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "In power systems, distribution boxes are commonly used electrical devices for distributing electrical energy and controlling circuits. Combined distribution boxes typically consist of a main distribution box and a secondary distribution box. In practical applications, distribution boxes need to be easy to assemble and disassemble to improve installation and maintenance efficiency. However, existing combined distribution boxes may suffer from complex operation and poor stability during assembly, and it is difficult to effectively prevent non-professionals from arbitrarily disassembling the secondary distribution box, which may lead to circuit failures or safety hazards." Considering practical use, this problem is clearly real and difficult to solve. Therefore, to solve this technical problem, a combined distribution box is provided.

[0031] like Figure 1-9 As shown in the figure;

[0032] Based on the above, the system includes a main distribution box 1 and a pair of auxiliary distribution boxes 2. The pair of auxiliary distribution boxes 2 are installed on the left and right sides of the main distribution box 1 via a convenient disassembly assembly 3. The convenient disassembly assembly 3 includes a guide block 31 fixed to the side wall of the main distribution box 1 and a guide block 32 fixed to the side wall of the auxiliary distribution box 2, as well as a limiting mechanism 33 provided on the guide block 31. The guide block 32 has a guide hole 321. The limiting mechanism 33 includes a sliding cavity 331 opened on the guide block 31. A sliding plate 332 is provided inside the sliding cavity 331. A guide rod 333 is fixed at one end of the sliding plate 332, and a guide seat 334 is fixed at the other end of the sliding plate 332.

[0033] The guide seat 334 has an annular groove 335 and an insertion hole 336 at one end. The annular groove 335 communicates with the insertion hole 336. One end of the pull ring 337 can be inserted into the annular groove 335 through the insertion hole 336. Rotating the pull ring 337 limits that end of the pull ring 337 to the annular groove 335, thereby connecting the pull ring 337 to the guide seat 334. Rotating the pull ring 337 in the opposite direction and disengaging it from the annular groove 335 completes the disassembly of the pull ring 337 from the guide seat 334. In the connected state, the guide seat 334 can be moved by pulling the pull ring 337.

[0034] The guide groove of the guide block 31 is a dovetail groove, and the shape of the guide block 32 is adapted to the dovetail groove to achieve a stable sliding connection between the auxiliary distribution box 2 and the main distribution box 1 in the horizontal direction.

[0035] The support plate 43 is fixed to the bottom of the left clamping mechanism 41 and the right clamping mechanism 42 by welding to ensure the stability of the connection.

[0036] An elastic element 338 is provided inside the sliding cavity 331. One end of the elastic element 338 abuts against the inner wall of the sliding cavity 331, and the other end abuts against the sliding plate 332. When the pull ring 337 is not pulled by an external force, the elastic element 338 keeps the sliding plate 332 in its initial position.

[0037] The end of the guide rod 333 is provided with a positioning head. The inner diameter of the guide hole 321 is adapted to the outer diameter of the positioning head. When the auxiliary distribution box 2 and the main distribution box 1 are installed in place, the positioning head can be inserted into the guide hole 321 to achieve positioning.

[0038] The outer surface of the pull ring 337 is provided with anti-slip texture to increase the friction when the operator holds the pull ring 337, making it easier to operate.

[0039] Assembly process

[0040] When assembling the modular distribution box, first align the auxiliary distribution box 2 with the dovetail groove of the guide block 31 on the main distribution box 1 via the guide block 32. Then, slide the auxiliary distribution box 2 horizontally along the dovetail groove to bring it closer to the main distribution box 1. When the auxiliary distribution box 2 and the main distribution box 1 are close to the installation position, the positioning head at the end of the guide rod 333 will automatically insert into the guide hole 321 on the guide block 32 to achieve precise positioning.

[0041] At this point, one end of the pull ring 337 is inserted into the annular groove 335 of the guide seat 334 through the insertion hole 336. The pull ring 337 is then rotated, causing that end of the pull ring 337 to be limited by the annular groove 335, thus completing the connection between the pull ring 337 and the guide seat 334. Under the action of the elastic element 338, the slide 332 is in its initial position, ensuring the stability of the limiting mechanism 33.

[0042] Prevent unauthorized dismantling

[0043] During normal use of the distribution box, operators can rotate the pull ring 337 in the opposite direction to disengage it from the ring groove 335, thus separating the pull ring 337 from the guide seat 334, and properly store the pull ring 337. Since non-professionals do not have the pull ring 337, they cannot operate the limit mechanism 33, making it difficult to remove the auxiliary distribution box 2 from the main distribution box 1. This effectively prevents unauthorized personnel from arbitrarily disassembling the auxiliary distribution box 2, ensuring the safe operation of the distribution box.

[0044] In summary, the modular distribution box of this utility model, through its reasonable structural design, not only achieves the purpose of easy assembly, but also prevents unauthorized personnel from disassembling the auxiliary distribution box through the removal of the pull ring, thus possessing high practical value and promotional significance.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
