Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical distribution box bracket technology, and more specifically, to an adjustable electrical distribution box mounting bracket. Background Technology
[0002] In the field of electrical equipment installation, electrical distribution boxes, as core components for power distribution and control, need to be fixed to walls or other supporting structures using specialized mounting brackets to ensure installation stability and operational safety. Currently, most commercially available electrical distribution box mounting brackets are fixed, meaning the spacing between the supporting components is predetermined during manufacturing and cannot be flexibly adjusted according to the actual dimensions of the distribution box to be installed.
[0003] Specifically, when electrical distribution boxes of different sizes need to be installed, operators need to purchase additional mounting brackets with corresponding spacing specifications according to the specific size of the distribution box. If there are no brackets of suitable specifications on site, it is often necessary to modify the existing brackets by secondary processing methods such as cutting and welding to adjust the spacing of the supporting components. Even if no secondary processing is required, it is necessary to reserve a variety of brackets with different spacing specifications to meet different installation needs. This fixed-spacing design firstly leads to poor adaptability and insufficient installation flexibility. One type of bracket can only match a single or very small range of distribution boxes, making it difficult to quickly adapt to diverse distribution box size requirements, greatly limiting the flexibility of installation scenarios. Secondly, it causes low installation efficiency and high operating costs. When the size of the distribution box does not match the existing bracket spacing, either new matching brackets are purchased, extending the installation cycle, or the existing brackets are reprocessed, increasing labor and material costs and potentially affecting the structural stability of the bracket due to insufficient processing precision, thus creating safety hazards. Finally, it leads to serious resource waste. To meet the installation needs of different sized distribution boxes, companies or construction parties need to stock multiple specifications of installation brackets, resulting in bracket inventory backlog and material waste. At the same time, the discarded bracket components after reprocessing further exacerbate resource consumption and environmental burden. Therefore, it needs to be improved. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an adjustable electrical distribution box mounting bracket, which has the advantage of being able to easily adjust the bracket spacing to adapt to distribution boxes of different sizes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable electrical distribution box mounting bracket, comprising:
[0006] A fixing plate, wherein a fixing block is fixedly sleeved inside the fixing plate;
[0007] The adjustment mechanism is disposed inside the fixed block;
[0008] The adjustment mechanism includes a fixed-end ratchet, the outer surface of which is fixedly sleeved with the interior of a fixed block. A movable-end ratchet is meshed with the back of the fixed-end ratchet, the outer surface of which is movably sleeved with the interior of the fixed block. A square rod is fixedly mounted on the front of the movable-end ratchet, a turning block is fixedly mounted on the front end of the square rod, a gear is movably sleeved on the outer surface of the square rod, the back of the gear is movably sleeved with the interior of the front of the fixed-end ratchet, a rack is meshed with the outer surface of the gear, and a bracket is fixedly mounted on the outer surface of the rack.
[0009] As a preferred embodiment of this utility model, a slider is fixedly installed on the outer surface of the bracket, and a round rod is movably sleeved inside the slider, with both ends of the round rod being fixedly connected to a fixing plate.
[0010] As a preferred embodiment of this utility model, a moving rod is movably sleeved inside the back of the moving end ratchet, a fixed sleeve is movably sleeved on the outer surface of the moving rod, a spring is fixedly installed at the rear end of the moving rod, and the rear end of the spring is fixedly connected to the inside of the fixed sleeve.
[0011] As a preferred embodiment of this utility model, a fixing rod is fixedly installed on the outer surface of the rack, a limiting block is slidably connected inside the fixing rod, and the rear end of the limiting block is fixedly connected to the fixing plate.
[0012] As a preferred embodiment of this utility model, the fixing plate is provided with bolts, and the outer surface of the fixing plate is fixedly mounted with an installation block.
[0013] As a preferred embodiment of this utility model, a reinforcing rod is provided on the outer surface of the bracket, and the reinforcing rod is connected to the bracket by bolts.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model effectively solves the problem of poor adaptability of existing fixed-spacing brackets through the design of the adjustment mechanism. Operators no longer need to purchase brackets of different specifications, nor do they need to perform secondary processing such as cutting and welding on the brackets. Simply by pushing and turning the adjusting block, the brackets can be moved in opposite directions, quickly adapting to distribution boxes of different sizes, significantly improving installation flexibility and efficiency, and shortening the installation cycle.

[0022] 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.
[0023] like Figures 1 to 5 As shown, this utility model provides an adjustable electrical distribution box mounting bracket, comprising:
[0024] Fixed plate 1, with fixed block 2 fixedly sleeved inside fixed plate 1;
[0025] The adjustment mechanism is located inside the fixed block 2;
[0026] The adjustment mechanism includes a fixed end face ratchet 3, the outer surface of which is fixedly sleeved with the inside of the fixed block 2. The back of the fixed end face ratchet 3 is meshed with a moving end face ratchet 4, the outer surface of which is movably sleeved with the inside of the fixed block 2. A square rod 5 is fixedly installed on the front of the moving end face ratchet 4, a turning block 6 is fixedly installed at the front end of the square rod 5, a gear 7 is movably sleeved on the outer surface of the square rod 5, the back of the gear 7 is movably sleeved with the inside of the front of the fixed end face ratchet 3, a rack 8 is meshed with the outer surface of the gear 7, and a bracket 9 is fixedly installed on the outer surface of the rack 8.
[0027] The fixed plate 1 serves as the basic load-bearing component of the entire mounting bracket, providing a stable installation benchmark for other structures. The fixed block 2, which is fixedly sleeved inside, is used to accommodate and limit the adjustment mechanism, ensuring that the adjustment mechanism operates stably within a preset range. The fixed end ratchet 3 in the adjustment mechanism is fixed in position by being fixedly sleeved with the fixed block 2. It can mesh with the moving end ratchet 4 to limit its rotation. The moving end ratchet 4 is movably sleeved with the fixed block 2, and can move back and forth with the square rod 5 to engage or disengage with the fixed end ratchet 3. The turning block 6 at the front end of the square rod 5 provides a force application point for the operator to push or turn the square rod 5. At the same time, the square design of the square rod 5 can drive the gear 7, which is movably sleeved on the outer surface, to rotate. The gear 7 is movably sleeved with the fixed end ratchet 3 to ensure the stability of the rotation axis. Its meshing with the rack 8 can convert its own rotational motion into the linear motion of the rack 8. Finally, the rack 8 drives the bracket 9 to move, realizing the adjustment of the bracket 9 spacing and providing suitable support for the installation of the distribution box.
[0028] The bracket 9 has a slider 10 fixedly installed on its outer surface. A round rod 11 is movably sleeved inside the slider 10, and both ends of the round rod 11 are fixedly connected to the fixing plate 1.
[0029] The slider 10 fixedly installed on the outer surface of the bracket 9 forms a sliding fit with the round rod 11. The round rod 11 is fixed in position by the fixed connection between its two ends and the fixed plate 1. When the bracket 9 moves under the drive of the rack 8, the slider 10 will slide along the outer surface of the round rod 11. This structure can guide the movement direction of the bracket 9, effectively avoid the bracket 9 from deviating or shaking during the movement, further improve the stability of the movement of the bracket 9, and ensure the precise adjustment of the bracket 9 spacing.
[0030] Among them, the moving end face ratchet 4 has a moving rod 12 movably sleeved inside the back side, the moving rod 12 has a fixed sleeve 13 movably sleeved on the outer surface of the moving rod 12, and a spring 14 is fixedly installed at the rear end of the moving rod 12. The rear end of the spring 14 is fixedly connected to the inside of the fixed sleeve 13.
[0031] The moving rod 12 on the back of the moving end ratchet 4 is movably connected to the fixed sleeve 13. The fixed sleeve 13 provides limit and guide for the forward and backward movement of the moving rod 12. The spring 14 fixed at the rear end of the moving rod 12 is fixedly connected to the inside of the fixed sleeve 13. When the operator pushes the turning block 6 to move the moving end ratchet 4 backward, the moving rod 12 will compress the spring 14. When the operator releases the turning block 6, the elastic force of the spring 14 will push the moving rod 12 to reset, thereby driving the moving end ratchet 4 to move forward and re-engage with the fixed end ratchet 3, thus realizing the automatic locking of the moving end ratchet 4.
[0032] Among them, a fixing rod 15 is fixedly installed on the outer surface of the rack 8, and a limit block 16 is slidably connected inside the fixing rod 15. The rear end of the limit block 16 is fixedly connected to the fixing plate 1.
[0033] The fixing rod 15, which is fixedly installed on the outer surface of the rack 8, is slidably connected to the limiting block 16. The limiting block 16 is fixed in position by the fixed connection between its rear end and the fixing plate 1. When the rack 8 moves under the drive of the gear 7, the fixing rod 15 will slide along the outer surface of the limiting block 16. This structure can limit the movement trajectory of the rack 8, prevent the rack 8 from deviating up or down or left or right during the movement, and ensure that the rack 8 drives the bracket 9 to move in opposite directions or in opposite directions stably and accurately, thus ensuring the reliability of the bracket 9 spacing adjustment.
[0034] Bolts are provided on the fixing plate 1, and mounting block 17 is fixedly installed on the outer surface of the fixing plate 1.
[0035] The bolts on the fixing plate 1 can further enhance the connection strength between the fixing plate 1 and the wall after the fixing plate 1 is initially fixed by the mounting block 17, and prevent the fixing plate 1 from loosening during long-term use. The mounting block 17, which is fixedly installed on the outer surface of the fixing plate 1, is used to initially install the fixing plate 1 on the target wall, providing a foundation for subsequent bolt fixing, ensuring that the installation process of the fixing plate 1 is orderly and stable, and laying the foundation for the safe use of the entire bracket.
[0036] The outer surface of the bracket 9 is provided with a reinforcing rod 18, which is connected to the bracket 9 by bolts.
[0037] The reinforcing rods 18 on the outer surface of the bracket 9 are connected to the bracket 9 by bolts, which can effectively enhance the structural strength of the bracket 9 and prevent the bracket 9 from bending or deforming when bearing the weight of the distribution box. Especially when the distribution box is large and heavy, the reinforcing rods 18 can distribute the pressure on the bracket 9, extend the service life of the bracket 9, and ensure the stability and safety of the distribution box after installation.
[0038] Working principle and usage process of this utility model:
[0039] First, the operator initially installs the fixing plate 1 onto the target wall using the mounting block 17 on the outer surface of the fixing plate 1. Then, the bolts compatible with the fixing plate 1 are screwed in sequentially to enhance the stability of the connection between the fixing plate 1 and the wall. Next, the operator measures the dimensions of the distribution box to be installed. After obtaining the measurement results, the operator pushes the rotating block 6, causing the rotating block 6 to drive the ratchet 4 on the moving end face of the square rod 5 to move backward along the interior of the fixing block 2. At this time, the ratchet 4 on the moving end face will simultaneously drive the moving rod 12 on its back to slide backward along the interior of the fixing sleeve 13. Since the rear end of the moving rod 12 is fixed to the interior of the fixing sleeve 13 with a spring 14, the backward movement of the moving rod 12 will affect the spring 14. 4. Compression occurs, and simultaneously, the moving end ratchet 4 gradually disengages from the back of the fixed end ratchet 3 during its backward movement. The original rotational restriction imposed by the fixed end ratchet 3 on the moving end ratchet 4 also disappears. At this point, the operator can turn the turning block 6. The turning block 6 will cause the square rod 5 and the moving end ratchet 4 to rotate together. Because the square rod 5 has a square design, the gear 7, which is movably sleeved on its outer surface, will rotate synchronously around the sleeve point inside the front of the fixed end ratchet 3 under the influence of the square rod 5. Since the outer surface of the gear 7 meshes with the rack 8, the rotation of the gear 7 will drive the rack 8 to move. At this time, the rack 8 will synchronously drive the bracket fixed on its outer surface. 9 and the fixed rod 15 move. Since the rear end of the limiting block 16, which is slidably connected inside the fixed rod 15, is fixed to the fixed plate 1, the limiting block 16 will restrict the movement direction of the fixed rod 15, so that the rack 8 can only drive the fixed rod 15 to move towards or away from each other along the outer surface of the limiting block 16. At the same time, the bracket 9 will move towards or away from each other synchronously under the drive of the rack 8, and the slider 10 fixed on the outer surface of the bracket 9 will slide along the outer surface of the round rod 11 fixed to the fixed plate 1 at both ends. The cooperation between the slider 10 and the round rod 11 can further improve the stability of the bracket 9 during movement. When the distance between the two brackets 9 is adjusted to match the measured size of the distribution box, the operator loosens the screw. The moving block 6, due to the restoring force of the compressed spring 14, pushes the moving rod 12 forward. The moving rod 12 then drives the moving end ratchet 4 to return forward along the inside of the fixed block 2. At this time, the moving end ratchet 4 will re-engage with the back of the fixed end ratchet 3. The fixed end ratchet 3 will then lock the rotation of the moving end ratchet 4 again to prevent the spacing of the brackets 9 from shifting during subsequent installation. After that, the operator can fix the distribution box to the top of the two brackets 9 with bolts. Since the outer surface of the bracket 9 is connected to the reinforcing rod 18 by bolts, the reinforcing rod 18 can effectively enhance the structural strength of the bracket 9 and ensure the load-bearing stability of the distribution box after installation.
