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 adjust. Background Technology

[0002] As a key device for power distribution and control, distribution boxes are widely used in various buildings and industrial facilities. Their function is to receive electrical energy input from the upstream transformer and distribute and control it rationally through internal electrical components. The internal structure of a distribution box typically includes a box body, guide rails, circuit breakers, residual current devices (RCDs), and various terminal blocks. Multiple sets of mounting brackets are provided on the upper and lower parts of the box body, and electrical components are fixed to the mounting brackets with fasteners.

[0003] Existing mounting bracket fixing methods require drilling holes in the inner wall of the enclosure according to the mounting hole positions on both sides of the bracket, and then connecting them with fasteners. This process is not only time-consuming and labor-intensive, but also makes it difficult to quickly adjust the vertical position of the mounting bracket inside the enclosure according to actual needs. Furthermore, drilling damages the structural integrity of the enclosure, and if the resulting metal shavings and powder are not thoroughly cleaned, they may reduce the electrical safety inside the enclosure, posing a risk of short circuits or grounding faults. To address these issues, the applicant has developed a beneficial design and found a solution. The technical solution described below arose from this context. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of traditional distribution box designs and provide a product that is easy to operate and flexible to adjust.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An easily adjustable distribution box includes a box body and a mounting bracket. At least one set of opposing sliding grooves are provided on both sides of the box body. A liftable slider is provided within each sliding groove. The mounting bracket is connected and fixed to the slider by fasteners. Each sliding groove has at least one structure to prevent the slider from detaching from the groove. Several equally spaced fixing grooves are provided on both sides of the sliding groove from top to bottom. At least one retractable fixing block is provided on both sides of the slider and embedded in the fixing groove for connecting and fixing the slider to the sliding groove. The slider has an operating element for controlling the fixing block to detach from the fixing groove and preventing the fixing block from resetting, thereby releasing the slider from the sliding groove.

[0007] Preferably, the mounting bracket has mounting portions extending from both ends of its sides, each mounting portion having a first mounting hole for accommodating fasteners, the mounting bracket having a plurality of equally spaced second mounting holes, and the slider having a rectangular third mounting hole adapted to the first mounting holes.

[0008] Preferably, the inlet of the fixing groove is provided with an inclined guide surface.

[0009] Preferably, the slide groove is provided with a guide portion and maintains a distance from the inner bottom of the box for the slider to enter the guide portion. The top two sides of the guide portion are provided with first anti-detachment portions, and the structure to prevent the slider from detaching from the slide groove is configured as the first anti-detachment portion.

[0010] Preferably, the slider is provided with a relief groove for the guide portion, and the two sides of the relief groove are provided with first anti-detachment grooves to accommodate the first anti-detachment portion.

[0011] Preferably, mounting grooves are provided on both sides of the spacing, a backstop is provided within the spacing, a connecting part is provided on both sides of the backstop and placed in the mounting groove, and a fastener is provided on the connecting part and threadedly connected to the mounting groove, so that the backstop is connected and fixed to the housing.

[0012] Preferably, the fixing block has a second anti-detachment part on both sides, and a first blind hole on the back of the fixing block. The first blind hole is equipped with a compression spring and acts on the slider.

[0013] Preferably, the slider has two recesses on both sides for accommodating the fixing block, and the recesses have second anti-detachment grooves on both sides that cooperate with the second anti-detachment part. The recesses have second blind holes for accommodating the compression spring, and the slider has a limiting groove between adjacent recesses. The limiting groove has a slot.

[0014] Preferably, the operating member is slidably disposed in the limiting groove and protrudes from the surface of the slider. The operating member has extensions on both sides and is connected and fixed to the adjacent fixing blocks by fasteners. The operating member has a liftable insert plate and is inserted into the slot to prevent the fixing block from extending out of the cavity.

[0015] Beneficial effects:

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes an operating mechanism to control the fixing block to detach from the fixing groove, allowing the slider to move freely along the groove direction, thereby adjusting the position of the mounting bracket in the vertical space within the housing. Applying downward pressure causes the insert plate to insert into the slot, preventing the operating mechanism from being pushed into the fixing groove by the reaction force of the compression spring, facilitating flexible adjustment of the mounting bracket's position. Once the mounting bracket is adjusted to the target position, pushing the insert plate out of the slot causes the compression spring force to quickly push the fixing block into the fixing groove, achieving a stable fixation of the mounting bracket. The above design allows for position adjustment without the need for tools. The slider has a third mounting hole to accommodate mounting brackets of different sizes, enhancing versatility. This structure effectively avoids damage to the housing structure and metal debris residue caused by drilling operations, eliminating potential hazards of short circuits or grounding faults, and improving the convenience and flexibility of the installation process.

[0039] Reference example Figures 1 to 7 An easily adjustable distribution box includes a box body 1 and a mounting bracket 2. At least one set of opposing sliding grooves 11 are provided on both sides of the box body 1. A liftable slider 3 is provided within each sliding groove 11. The mounting bracket 2 is connected and fixed to the slider 3 via fasteners 7. Each sliding groove 11 has at least one structure to prevent the slider 3 from detaching from the groove 11. Several equally spaced fixing grooves 12 are provided on both sides of the sliding groove 11 from top to bottom. Each slider 3 has at least one retractable fixing block 4 on both sides, which is embedded in the fixing groove 12 to connect and fix the slider 3 to the sliding groove 11. The slider 3 has an operating element 5 for controlling the fixing block 4 to detach from the fixing groove 12 and preventing the fixing block 4 from resetting, thereby releasing the slider 3 from the sliding groove 11.

[0040] It is worth mentioning that the mounting bracket 2 has mounting portions 21 extending from both ends of its sides. The mounting portions 21 have first mounting holes 22 for accommodating fasteners 7. The mounting bracket 2 has several second mounting holes 23 spaced 14 at equal intervals. The slider 3 has a rectangular third mounting hole 32 that fits the first mounting hole 22. To ensure that the slider 3 is in the relative position and to prevent the mounting bracket 2 from tilting during installation, the slider 3 can be connected and fixed to both sides of the mounting bracket 2 first, and then the entire structure can be placed into the slide groove 11. The electrical components are connected and fixed to the mounting bracket 2 through the second mounting holes 23. This structural design can effectively ensure the stability of the mounting bracket 2 during the adjustment process, avoid installation deviation due to uneven force, and improve the overall assembly accuracy and reliability.

[0041] It is worth mentioning that the entrance of the fixing groove 12 is provided with an inclined guide surface 121, which allows the fixing block 4 to smoothly enter the slide groove 11;

[0042] It is worth mentioning that the slide 11 is provided with a guide part 13 and maintains a distance 14 between it and the inner bottom of the box body 1 for the slider 3 to enter the guide part 13. The top two sides of the guide part 13 are provided with a first anti-detachment part 131. The structure to prevent the slider 3 from detaching from the slide 11 is set as the first anti-detachment part 131. The guide part 13 provides a guiding function for the lifting and lowering of the slider 3.

[0043] It is worth mentioning that the slider 3 is provided with a relief groove 31 that cooperates with the guide part 13, and the two sides of the relief groove 31 are provided with a first anti-detachment groove 311 to accommodate the first anti-detachment part 131;

[0044] It is worth mentioning that mounting grooves 15 are provided on both sides of the spacing 14, and anti-reverse parts 6 are provided in the spacing 14. Connecting parts 61 are provided on both sides of the anti-reverse parts 6 and placed in the mounting grooves 15. Fasteners 7 are provided on the connecting parts 61 and are threadedly connected to the mounting grooves 15, so that the anti-reverse parts 6 are connected and fixed to the housing 1. By disassembling the anti-reverse parts 6, sliders 3 can be added or removed in the slide groove 11 according to actual needs to adjust the number or layout of the mounting brackets 2. The anti-reverse parts 6 also have the function of preventing sliders 3 from falling out of the slide groove 11, ensuring that sliders 3 always remain in the predetermined track during operation, and avoiding the impact of accidental displacement on the overall structural stability.

[0045] It is worth mentioning that the fixed block 4 has a second anti-detachment part 41 on both sides and a first blind hole 42 on the back. The first blind hole 42 is equipped with a compression spring 8, which acts on the slider 3. The structure of the first blind hole 42 is designed to increase the upper limit of the energy storage of the compression spring 8. When the fixed block 4 retracts into the cavity 33, it can effectively limit the compression stroke of the compression spring 8, prevent it from losing elastic potential energy due to excessive compression, and thus ensure the stability and reliability of the spring for long-term use.

[0046] It is worth mentioning that the slider 3 has two cavities 33 on both sides to accommodate the fixed block 4. The cavities 33 have second anti-detachment grooves 34 on both sides to cooperate with the second anti-detachment part 41. The cavities 33 have second blind holes 35 to accommodate the compression spring 8. The slider 3 has a limiting groove 36 between adjacent cavities 33. The limiting groove 36 has a slot 37. The structure of the second anti-detachment groove 34 is designed to prevent the fixed block 4 from detaching from the cavity 33 during the extension and retraction process, ensuring that it moves stably along the direction of the cavity 33. The second blind hole 35 increases the upper limit of the energy storage of the compression spring 8, preventing the spring from detaching from the point of action during compression, and at the same time providing reliable support for the spring. The limiting groove 36 limits the range of motion of the operating part 5, thereby controlling the stroke of the fixed block 4 extending out of the cavity 33.

[0047] It is worth mentioning that the operating member 5 is slidably disposed in the limiting groove 36 and protrudes from the surface of the slider 3. The operating member 5 has extensions 51 on both sides and is connected and fixed to the adjacent fixing blocks 4 by fasteners 7. The operating member 5 has a liftable insert plate 52 and is inserted into the slot 37 to prevent the fixing block 4 from extending out of the cavity 33.

[0048] The working principle of this utility model is described as follows:

[0049] The operating component 5 controls the fixed block 4 to disengage from the fixed groove 12 and causes the compression spring 8 to enter the energy storage state, so that the slider 3 can move freely along the direction of the groove 11, thereby adjusting the position of the mounting bracket 2 in the vertical space of the housing 1.

[0050] As the operating component 5 contacts the initial end face of the limiting groove 36, the insert plate 52 and the slot 37 gradually overlap. At this time, the downward pressure is applied to insert the insert plate 52 into the slot 37, which can prevent the operating component 5 from being pushed into the fixing block 4 by the reaction force of the compression spring 8, so as to facilitate the flexible adjustment of the position of the mounting bracket 2.

[0051] Once the mounting bracket 2 is adjusted to the target position, push the insert plate 52 up and away from the slot 37. The compression spring 8 then quickly pushes the fixing block 4 into the fixing groove 12, thus achieving a stable fixation of the mounting bracket 2.

[0052] The above design allows for position adjustment without the need for tools. The slider 3 has a third mounting hole 32, which can be adapted to mounting brackets 2 of different sizes, enhancing versatility. This structure effectively avoids structural damage to the housing 1 and metal debris residue caused by drilling operations, eliminates potential hazards that may cause short circuits or grounding faults, and improves the convenience and flexibility of the installation process.

[0053] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
