Description

Technical Field

[0001] This invention belongs to the field of electrical distribution box installation technology, and particularly relates to an electrical distribution box mounting bracket. Background Technology

[0002] A distribution box, also known as a distribution cabinet, is the final stage equipment in a power distribution system. It is suitable for power supply in factories, mines, residential areas, rural areas, and infrastructure projects.

[0003] Distribution boxes are typically installed on external walls or utility poles, and mounting brackets are used to ensure their stability and ease of installation and removal.

[0004] However, existing mounting brackets cannot quickly position and fix the distribution box, making the installation process cumbersome and affecting installation efficiency.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a distribution box mounting bracket to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] The purpose of this invention is to provide a distribution box mounting bracket, which aims to solve the problem that existing mounting brackets cannot quickly position and fix the distribution box, and the installation steps are cumbersome.

[0007] This invention is implemented as follows: a distribution box mounting bracket includes a support base, a back plate fixedly mounted on one side of the support base, and a pressing and securing mechanism. The support base has a moving mechanism on its inner side, and the pressing and securing mechanism is mounted on the moving mechanism. The moving mechanism supports the pressing and securing mechanism and drives it to move relative to the back plate. A positioning ring is fixedly mounted on the bottom of the distribution box. When the distribution box is placed on the pressing and securing mechanism, the pressing and securing mechanism abuts against the side of the positioning ring and, in conjunction with the moving mechanism, drives the pressing and securing mechanism and the distribution box to move until the distribution box and the back plate abut against each other, thus achieving the positioning and fixing of the distribution box.

[0008] A further technical solution includes a moving mechanism comprising a horizontal threaded shaft, a first knob, a first fixing screw, a guide rail, and a moving seat. The inner side of the support has an installation groove, and a guide rail is fixed to both sides of the bottom of the installation groove. The moving seat is located within the installation groove and is slidably connected to both guide rails. A horizontal threaded shaft is rotatably mounted in the center of the bottom of the support, and the horizontal threaded shaft is also threadedly connected to the moving seat. A first knob is also fixed to the end of the horizontal threaded shaft away from the back plate. The support also has a first fixing screw for locking and fixing the horizontal threaded shaft.

[0009] A further technical solution includes an outer cylinder, an end cap, an inner column, a retaining rod, an outer support wheel, an inner support wheel, and a support shaft. The outer cylinder is fixedly mounted on a movable base. The outer cylinder has multiple strip-shaped openings distributed circumferentially. A support shaft is fixedly mounted in each of the strip-shaped openings. A retaining rod is rotatably mounted on the support shaft. The inner and outer ends of the retaining rod are respectively equipped with an inner support wheel and an outer support wheel. The inner column is slidably mounted inside the outer cylinder, and the top of the inner column is equipped with an end cap. When the distribution box is placed on the end cap, the inner column pushes the inner support wheel downward until the outer support wheel abuts against the side of the positioning ring.

[0010] In a further technical solution, the length of the retaining rod between the support shaft and the outer support wheel is greater than the length of the retaining rod between the support shaft and the inner support wheel.

[0011] A further technical solution is provided, in which a cavity is provided on the inner side of the inner cylinder, a slider is slidably provided in the cavity, a guide rod is fixed on the lower side of the slider, the guide rod extends out from the bottom of the inner cylinder and its lower end is fixed to the inner bottom of the outer cylinder, and a spring is also sleeved on the guide rod on the lower side of the inner cylinder.

[0012] In a further technical solution, several supporting balls are installed on both sides of the mounting groove at the top of the support; when the outer support wheel is fixed to the side of the positioning ring, the bottom of the distribution box abuts against the supporting balls, the end cap abuts against the upper end of the outer cylinder, and the inner support wheel abuts against the inner side of the bottom of the strip opening.

[0013] In a further technical solution, the positioning ring is a circular ring structure, and the outer side of the positioning ring is an arc-shaped concave structure.

[0014] In a further technical solution, two fixing grooves are provided at one end of the support near the back plate, and fixing holes are provided at both the upper and lower ends of the back plate. The fixing holes at the lower part of the back plate are used to pass through the first fixing bolt and fix the back plate in the fixing groove of the support.

[0015] A further technical solution is that the lower end face of the back plate protrudes from the lower surface of the support; an elastic pad is also provided on the side of the back plate near the distribution box.

[0016] A further technical solution includes an auxiliary fixing mechanism for auxiliary fixing of the side of the distribution box. The auxiliary fixing mechanism includes a second knob, a second fixing screw, an inner rod, a first bevel gear, a fixing head, a fixing ring, a threaded cylinder, a second fixing bolt, a fixing bracket, a diagonal connecting rod, a support ring, a vertical threaded shaft, and a second bevel gear. An inner rod passes through the inner side of the horizontal threaded shaft and is slidably and rotatably connected to it. A second knob is fixed to the end of the inner rod away from the back plate. A second fixing screw for locking the inner rod is also provided on the horizontal threaded shaft. A second knob is installed at the end of the inner rod near the back plate. A first bevel gear is fixedly mounted on the device. A fixing frame is fixed between the two back plates by a second fixing bolt. A threaded cylinder is slidably mounted on the fixing frame. The threaded cylinder is also provided with a guide ridge. A fixing head is fixedly mounted on the upper end of the threaded cylinder and can be welded and fixed to the rear side of the distribution box. The fixing head adopts a frustum structure. A vertical threaded shaft is threadedly connected to the threaded cylinder. A second bevel gear that can mesh with the first bevel gear is fixedly mounted on the lower end of the vertical threaded shaft. A support ring is also rotatably mounted on the vertical threaded shaft. The support ring is connected and fixed to the fixing frame by a diagonal connecting rod.

[0017] The present invention provides a distribution box mounting bracket, which can weld a fixing positioning ring to the bottom of a conventional distribution box. After the distribution box is placed on the pressing and fixing mechanism, the weight of the distribution box can make the pressing and fixing mechanism abut against the side of the positioning ring, so that the distribution box is initially positioned. Then, the moving mechanism is operated to drive the pressing and fixing mechanism and the distribution box to move until the distribution box and the back plate are against each other, and the distribution box cannot be rotated, thereby achieving the overall positioning and fixing of the distribution box.

[0018] This device allows for quick and convenient installation and fixing of distribution boxes. It eliminates the need for complicated installation steps, enabling the distribution box to be positioned and fixed quickly and reliably, thus improving installation efficiency.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] like Figures 1-6 As shown, an embodiment of the present invention provides a distribution box mounting bracket, including a bracket 5, a back plate 4 fixedly mounted on one side of the bracket 5, and further comprising:

[0033] The pressing and securing mechanism has a moving mechanism on the inner side of the support 5. The pressing and securing mechanism is mounted on the moving mechanism, which is used to support the pressing and securing mechanism and drive it to move relative to the back plate 4.

[0034] Positioning ring 20 is installed and fixed at the bottom of distribution box 1. When distribution box 1 is placed on pressing and fixing mechanism, pressing and fixing mechanism abuts against the side of positioning ring 20, and cooperates with moving mechanism to drive pressing and fixing mechanism and distribution box 1 to move until distribution box 1 and back plate 4 abut against each other, realizing the positioning and fixing of distribution box 1.

[0035] In this embodiment of the invention, a positioning ring 20 can be welded to the bottom of a conventional distribution box 1. After the distribution box 1 is placed on the pressing and securing mechanism, the weight of the distribution box 1 can be used to make the pressing and securing mechanism abut against the side of the positioning ring 20, so that the distribution box 1 is initially positioned. Then, the moving mechanism is operated to drive the pressing and securing mechanism and the distribution box 1 to move until the distribution box 1 and the back plate 4 are against each other, and the distribution box 1 cannot be rotated, thereby realizing the overall positioning and fixing of the distribution box 1.

[0036] This device allows for quick and convenient installation and fixing of the distribution box 1. It can achieve overall positioning and fixing of the distribution box 1 without complicated installation steps, enabling the distribution box 1 to be installed quickly and reliably, thus improving installation efficiency.

[0037] like Figures 1-2 As shown, in a preferred embodiment of the present invention, the moving mechanism includes a horizontal threaded shaft 8, a first knob 9, a first fixing screw 11, a guide rail 14, and a moving seat 18. The inner side of the support 5 has a mounting groove 10, and a guide rail 14 is fixed to both sides of the bottom of the mounting groove 10. The moving seat 18 is disposed within the mounting groove 10 and is slidably connected to both guide rails 14, allowing for stable guidance of the moving seat 18. A horizontal threaded shaft 8 is rotatably mounted in the center of the bottom of the support 5, and is threadedly connected to the moving seat 18. A first knob 9 is fixed to the end of the horizontal threaded shaft 8 away from the back plate 4, allowing rotation of the horizontal threaded shaft 8 via the first knob 9. The support 5 also has a first fixing screw 11 for locking and fixing the horizontal threaded shaft 8, which is used to fix the horizontal threaded shaft 8 after adjustment. In application, rotating the first knob 9 on the horizontal threaded shaft 8 drives the moving seat 18 to move along the guide rail 14.

[0038] like Figures 1-6As shown, in a preferred embodiment of the present invention, the pressing and securing mechanism includes an outer cylinder 7, an end cap 13, an inner column 16, a securing rod 17, an outer support wheel 21, an inner support wheel 22, and a support shaft 23. The outer cylinder 7 is mounted and fixed on a movable seat 18. The outer cylinder 7 has multiple strip-shaped openings 15 distributed circumferentially. A support shaft 23 is installed and fixed in each strip-shaped opening 15. A securing rod 17 is rotatably mounted on the support shaft 23. The inner and outer ends of the securing rod 17 are respectively equipped with an inner support wheel 22 and an outer support wheel 21. The inner column 16 is slidably disposed inside the outer cylinder 7. The top of the inner column 16 is provided with an end cap 13. When the distribution box 1 is placed on the end cap 13, the inner column 16 pushes the inner support wheel 22 downward until the outer support wheel 21 is secured to the side of the positioning ring 20.

[0039] In one embodiment, the length of the retaining rod 17 between the support shaft 23 and the outer support wheel 21 is greater than the length of the retaining rod 17 between the support shaft 23 and the inner support wheel 22. This facilitates the inner column 16 and the end cap 13 to rise again and return to their original positions by the gravity of the retaining rod 17 and the outer support wheel 21 after the distribution box 1 is removed. To improve the reliability of the device, a cavity 24 is provided on the inner side of the inner column 16, and a slider 25 is slidably provided in the cavity 24. A guide rod 26 is fixed on the lower side of the slider 25. The guide rod 26 extends slidably from the bottom of the inner column 16 and its lower end is fixed to the inner bottom of the outer cylinder 7. A spring 27 is also sleeved on the guide rod 26 on the lower side of the inner column 16. The spring 27 can provide elastic support for the inner column 16, which is conducive to the inner column 16 returning to its original position. The slider 25 and the guide rod 26 can limit and guide the inner column 16, thereby improving reliability.

[0040] In one embodiment, several supporting balls 12 are installed on both sides of the mounting groove 10 at the top of the support 5. The supporting balls 12 can provide auxiliary support for the distribution box 1 and facilitate the stable movement of the distribution box 1 by the moving mechanism. When the outer support wheel 21 is fixed to the side of the positioning ring 20, the bottom of the distribution box 1 abuts against the supporting balls 12, the end cap 13 abuts against the upper end of the outer cylinder 7, and the inner support wheel 22 abuts against the inner side of the bottom of the strip opening 15. The setting of the outer support wheel 21 and the inner support wheel 22 can reduce friction and improve stability. In addition, it is preferable to round the outer edge of the lower end of the inner column 16 to facilitate the movement of the inner support wheel 22 by the inner column 16. The positioning ring 20 has a circular structure and the outer side of the positioning ring 20 has an arc-shaped concave structure, which improves the reliability of the outer support wheel 21 abutting against the side of the positioning ring 20.

[0041] In this embodiment of the invention, the inner diameter of the positioning ring 20 can be set larger than the outer diameter of the end cap 13, which facilitates the placement of the distribution box 1 on the end cap 13 and improves installation efficiency. It is sufficient that after the distribution box 1 presses against the end cap 13, the outer support wheel 21 can abut against the side of the positioning ring 20. The arrangement of multiple outer support wheels 21 abutting against the side of the positioning ring 20 ensures reliable positioning of the distribution box 1 and restricts its movement, providing stability and reliability. Furthermore, the use of a moving mechanism to abut against the back plate 4 restricts the rotation of the distribution box 1, ensuring stable positioning and installation of the distribution box 1.

[0042] like Figure 1 and 3 As shown, in a preferred embodiment of the present invention, the mounting groove 10 can be arranged as needed and is not limited; the support 5 has two fixing grooves 6 at one end near the back plate 4, and fixing holes 2 are provided at both the upper and lower ends of the back plate 4. The fixing holes 2 at the lower part of the back plate 4 are used to pass through the first fixing bolt 19 and fix the back plate 4 in the fixing groove 6 of the support 5; preferably, the lower end surface of the back plate 4 protrudes from the lower surface of the support 5 to improve the reliability of the back plate 4 supporting the support 5.

[0043] The back plate 4 is also provided with an elastic pad 3 on the side near the distribution box 1. The elastic pad 3 can provide elastic support for the distribution box 1, thereby improving the installation reliability and effectiveness of the distribution box 1.

[0044] In this embodiment of the invention, the two back plates 4 facilitate the suspension or wall-mounting of the distribution box 1, providing a reliable and stable support for the bracket 5.

[0045] like Figures 7-10As shown, in a preferred embodiment of the present invention, an auxiliary fixing mechanism 28 for auxiliary fixing of the side of the distribution box 1 is further included. The auxiliary fixing mechanism 28 includes a second knob 29, a second fixing screw 30, an inner rod 31, a first bevel gear 32, a fixing head 33, a fixing ring 34, a threaded cylinder 35, a second fixing bolt 37, a fixing bracket 38, a diagonal connecting rod 39, a support ring 40, a vertical threaded shaft 41, and a second bevel gear 42. An inner rod 31 is inserted through the inner side of the horizontal threaded shaft 8. The inner rod 31 is slidably and rotatably connected to the horizontal threaded shaft 8, that is, the inner rod 31 can slide and rotate relative to the horizontal threaded shaft 8. The second knob 29 is fixedly installed at the end of the inner rod 31 away from the back plate 4. The second fixing screw 30 for locking the inner rod 31 is also provided on the horizontal threaded shaft 8. The inner rod 31 is fixedly installed at the end near the back plate 4. A first bevel gear 32; a fixing frame 38 is installed and fixed between the two back plates 4 by a second fixing bolt 37. A threaded cylinder 35 is slidably provided on the fixing frame 38. To prevent the threaded cylinder 35 from twisting, a guide rib 36 is also provided on the threaded cylinder 35. A fixing head 33 is installed and fixed at the upper end of the threaded cylinder 35, which can be welded and fixed to the rear side of the distribution box 1. The fixing head 33 preferably adopts a frustum structure. A vertical threaded shaft 41 is internally threaded to the threaded cylinder 35. A second bevel gear 42 that can mesh with the first bevel gear 32 is installed and fixed at the lower end of the vertical threaded shaft 41. A support ring 40 is also rotatably installed on the vertical threaded shaft 41. The support ring 40 is connected and fixed to the fixing frame 38 by a diagonal connecting rod 39. The vertical threaded shaft 41 can be rotatably supported by the diagonal connecting rod 39 and the support ring 40.

[0046] In this embodiment of the invention, when the moving mechanism is working, the inner rod 31 can be pulled first to separate the first bevel gear 32 and the second bevel gear 42, so that the operation of the moving mechanism is not affected (the second fixing screw 30 can be locked or not locked, preferably locked); when it is necessary to operate the auxiliary fixing mechanism 28, the first fixing screw 11 is operated to fix the horizontal threaded shaft 8, so that the horizontal threaded shaft 8 cannot be rotated, and then the inner rod 31 is pushed to make the first bevel gear 32 mesh with the second bevel gear 42. Then, by operating the second knob 29 to rotate the inner rod 31, the first bevel gear 32 can drive the second bevel gear 42 to rotate. Since the vertical threaded shaft 41 is threadedly connected to the threaded cylinder 35, the threaded cylinder 35 can be raised and lowered to realize the connection and separation of the fixing head 33 and the fixing ring 34. In addition, the structure of the fixing head 33 limits the stability of the distribution box 1 after the fixing head 33 is inserted and fixed to the fixing ring 34, resulting in a good fixing effect. When the back plate 4 is fixed to the wall, in order to ensure that the auxiliary fixing mechanism 28 has sufficient installation space, shims can be used appropriately. That is, shims matching the bolts are arranged on the fixing holes 2. This ensures that the installation and operation space of the auxiliary fixing mechanism 28 is guaranteed while ensuring the overall installation of the distribution box 1 is reliable. No specific limitations or elaborations are made.

[0047] The above embodiments of the present invention provide a distribution box mounting bracket, which only requires welding two components, a positioning ring 20 and a fixing ring 34, onto the traditional distribution box 1 as needed. The coordinated operation of the moving mechanism and the pressing and securing mechanism can achieve overall positioning and fixation of the distribution box 1 after it abuts against the back plate 4. In addition, by defining the auxiliary fixing mechanism 28, the side auxiliary fixing of the distribution box 1 can be further achieved, ensuring the overall stable and reliable installation of the distribution box 1.

[0048] Furthermore, there are no limitations on the model and specific connection of each component, which can be flexibly set in actual application; the circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this invention does not involve the improvement of software and methods.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
