Description

Technical Field

[0001] This invention relates to the technical field of low-voltage distribution cabinets, specifically to a base mounting mechanism for installing low-voltage distribution boxes. Background Technology

[0002] The base mounting mechanism of a low-voltage distribution cabinet is an important component to ensure the stable and safe operation of the distribution cabinet. The base mounting mechanism can provide stable support for the distribution cabinet, ensuring that it will not tilt or shake due to uneven ground or external forces during operation. Secondly, the base can also prevent moisture, water and small animals from entering the distribution cabinet, protecting electrical components from damage.

[0003] The bases currently on the market are usually made of 10# or 12# channel steel. The channel steel is precisely cut according to the size and installation position of the distribution cabinet. Then, the cut channel steel is welded into a frame. Four support members are welded to the bottom of the frame. Finally, angle steel is installed on the outside of the support members. The installation work between the mechanism and the ground is completed by the angle steel. After the installation is completed, the distribution cabinet is placed on the channel steel, which can achieve the effect of supporting the installation of the distribution cabinet.

[0004] While the aforementioned mounting mechanisms are low-cost, their dimensions are fixed, and the size of low-voltage distribution cabinets may vary depending on the model, manufacturer, or specific functional requirements. The fixed dimensions of these base mounting mechanisms prevent them from fitting distribution cabinets of different sizes, resulting in a high scrap rate and poor flexibility. Furthermore, when adjustments or replacements to the distribution cabinet are needed, the fixed-size mounting mechanisms may not provide sufficient flexibility. For example, if the installation angle or position of the distribution cabinet needs adjustment, the fixed-size base may not meet the requirements, necessitating the remanufacturing or adjustment of the base, thus wasting materials and increasing costs. Summary of the Invention

[0005] The purpose of this invention is to provide a base mounting mechanism for low-voltage distribution boxes, addressing the shortcomings of existing market mounting mechanisms. While these mechanisms are low-cost, their fixed dimensions mean that the size of low-voltage distribution cabinets can vary depending on the model, manufacturer, or specific functional requirements. The fixed dimensions of these base mounting mechanisms prevent them from accommodating distribution cabinets of different sizes, leading to a high scrap rate and poor flexibility. Furthermore, when adjustments or replacements are needed, the fixed-size mechanism may not provide sufficient flexibility. For example, if the installation angle or position of the distribution cabinet needs adjustment, a fixed-size base may not meet the requirements, necessitating remanufacturing or adjustment, resulting in material waste and increased costs.

The bottom of the limit rods is provided with omnidirectional wheels, and the lowest point of the omnidirectional wheels is on the same plane as the lowest point of the support column.

[0017] Preferably, the pushing assembly includes a driving mechanism, a rotating disk, and a pushing mechanism. The driving mechanism is disposed on the outer side of the rotating disk and is used to drive the rotating disk to rotate.

This ensures that when the power distribution cabinet is placed on top of it, there will be no excessive heat concentration. This makes the installation mechanism not only more flexible and adaptable, but also does not affect the heat dissipation of the power distribution cabinet. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-7 The present invention provides a technical solution: a base mounting mechanism for installing a low-voltage distribution box, including a support component 4, which is set on the ground and used for supporting the installation of the low-voltage distribution cabinet;

[0034] Also includes;

[0035] The retractable component has a rectangular structure and specifically includes a first moving module 2 and a second moving module 3. Two of each of the first moving module 2 and the second moving module 3 are symmetrically arranged. The first moving module 2 and the second moving module 3 are arranged perpendicularly to each other, and the height of the first moving module 2 is lower than the height of the second moving module 3.

[0036] The movable plate 6 is fixedly installed at the bottom of both the first movable module 2 and the second movable module 3. Reset components 5 are provided on both sides of the movable plate 6 and connected to the outer wall of the support component 4.

[0037] The push component 7 is located at the center of the support component 4, and its top is used to push the moving plate 6 to move. The movement of the moving plate 6 drives the first moving module 2 and the second moving module 3 to move, thereby achieving the purpose of controlling the retraction and extension components to retract and extend.

[0038] The first moving module 2 includes a first frame 21, a first moving block 22, a protruding plate 23, and a first friction pad 24. The first frame 21 is symmetrically arranged at the top of the support component 4, and its inner side is set as a hollow structure. The first moving block 22 is arranged in the hollow structure inside the first frame 21. The protruding plate 23 is integrally installed at the top of the first moving block 22, and the first friction pad 24 is arranged at the top of the protruding plate 23.

[0039] The second moving module 3 includes a second frame 31, a second moving block 32, a connecting plate 33, and a second friction pad 34. The two sides of the second frame 31 are fixed to the top of the two first frames 21, and the second moving block 32 is provided in the hollow structure inside the second frame 31. The top of the second moving block 32 is provided with the second friction pad 34, and the connecting plate 33 is integrally installed on the top and bottom of the second moving block 32.

[0040] The first friction pad 24 and the second friction pad 34 are at the same height. Rollers 1 are evenly arranged on the lower inner walls of the first frame 21 and the second frame 31. A movable plate 6 is integrally installed on the bottom of the first frame 21 and the bottom of the connecting plate 33.

[0041] This application provides a mounting mechanism for a low-voltage distribution cabinet base with a retractable assembly. Specifically, in use, firstly, the retractable support assembly 4 is fixed to the ground using external angle steel. Then, the retractable assembly can be unfolded according to the different sizes of the low-voltage distribution cabinet. During unfolding, the pushing assembly 7 inside the support assembly 4 needs to be activated, causing its top to push the four movable plates 6 outside the support assembly 4. This causes the movable plates 6 to move outward under the action of the reset assembly 5. When the movable plates 6 move outward... The top of each component will drive the first moving block 22 and the second moving block 32 to move, thereby causing the first moving block 22 and the second moving block 32 to extend out of the first frame 21 and the second frame 31 respectively. As a result, the positions of the first friction pad 24 and the second friction pad 34 at the top of the first moving block 22 and the second moving block 32 will change. When the first friction pad 24 and the second friction pad 34 reach the appropriate position, the power distribution cabinet can be placed and installed. In this application, the material of the friction pad can be any one of rubber pad, anti-slip rubber plate or polyurethane pad.

[0042] After the power distribution cabinet is placed, since the surfaces of the first moving block 22 and the second moving block 32 are both meshed and they are distributed vertically, it is ensured that the power distribution cabinet will not have excessive heat concentration after installation.

[0043] Since the roller 1 is installed inside both the first frame 21 and the second frame 31, the movement of the first moving block 22 and the second moving block 32 is made more continuous and there will be no movement jamming.

[0044] Among them, according to Figure 3 As shown, the support assembly 4 includes a support base plate 41, support columns 42 and connecting frame 43. The connecting frame 43 is integrally installed on the outer top of the support base plate 41, and support columns 42 are integrally installed at the four top corners of the bottom of the support base plate 41.

[0045] The base plate 41 is used to place and install the pushing component 7, the connecting frame 43 is used to install the first moving module 2, and the support column 42 is set to facilitate the subsequent fitting of the angle steel. The support column 42 is installed on the ground by the angle steel, thus completing the installation of the Zhenggege support component 4.

[0046] Furthermore, according to Figure 6 As shown, the reset assembly 5 includes a fixed post 51, a connecting post 52, a reset spring 53, and a limiting plate 54. One side of the fixed post 51 is fixed to the outside of the connecting frame 43, and a movable connecting post 52 is provided on its inner side. The bottom of the connecting post 52 is fixed to the limiting plate 54, and a reset spring 53 is provided on the outside of the connecting post 52. The top of the connecting post 52 is fixedly installed on the inner side of the movable plate 6.

[0047] When the movable plate 6 moves outward, its inner side pulls the connecting column 52 outward. When the connecting column 52 moves outward, it pulls the limiting plate 54 to squeeze the reset spring 53. This ensures that when the inner side of the movable plate 6 is not pushed by the pushing component 7, it will reset under the action of the reset spring 53. This allows the subsequent retraction component to be automatically retracted, making it convenient for storage and transfer.

[0048] As a further preferred embodiment, according to Figure 5 As shown, limit components 8 are provided on both sides of the outer side of the movable plate 6, and the limit components 8 include a limit rod 81 and a movable caster 82. The bottom of the limit rod 81 is provided with a movable caster 82, and the lowest point of the movable caster 82 is on the same plane as the lowest point of the support column 42.

[0049] In this application, when the movable plate 6 moves, the limit rods 81 on both sides will also move. With the help of the movable casters 82 at the bottom of the limit rods 81, the outer side of the movable plate 6 will be limited and supported, so that when the power distribution cabinet is installed and placed, the top of the movable plate 6 will not be subjected to excessive force and breakage will not occur.

[0050] As a further preferred embodiment, according to Figure 3-4 As shown, the pushing component 7 includes a driving mechanism 71, a rotating disk 72, and a pushing mechanism 73. The driving mechanism 71 is located on the outer side of the rotating disk 72 and is used to drive the rotating disk 72 to rotate. The rotating disk 72 has reserved grooves 721 distributed at equal angles on its surface, and the pushing mechanism 73 is located on the inner side of the reserved grooves 721. The top of the pushing mechanism 73 is in contact with the inner side of the moving plate 6.

[0051] The drive mechanism 71 includes a drive motor 711 and a drive gear 712. The top of the drive motor 711 is coaxially connected to the drive gear 712, and the outer side of the drive gear 712 meshes with the tooth block on the outer wall of the rotating disk 72. The bottom of the rotating disk 72 is connected to the top bearing of the support base plate 41.

[0052] The pushing mechanism 73 includes a pushing rod 731, a moving component 732, a fixing plate 733, and protruding rods 734. The top end of the pushing rod 731 passes through a perforation on the outer wall of the connecting frame 43, and the moving component 732 on the outside of the pushing rod 731 is set inside the reserved slot 721. The top end of the pushing rod 731 is integrally mounted with the fixing plate 733, and the top end of the fixing plate 733 is provided with protruding rods 734 at equal intervals.

[0053] The moving component 732 includes a slider and a connecting shaft. The slider slides inside the reserved slot 721, and the bottom of the slider is provided with a pulley that slides in a slide rail on the surface of the support base plate 41. The top of the slider is connected to the push rod 731 through the connecting shaft.

[0054] When the drive assembly 7 is in operation, the drive motor 711 needs to be started first, so that it drives the drive gear 712 at its top to rotate. When the drive gear 712 rotates, it will mesh with the toothed block on the outer wall of the rotating disk 72, thereby causing the rotating disk 72 to drive the reserved slot 721 above it to rotate. When the reserved slot 721 rotates, it will drive the moving assembly 732 in the middle to move. Therefore, the moving assembly 732 drives the push rod 731 at its top to move back and forth in the through hole. When the push rod 731 moves, it drives the fixed plate 733 at its top to move. When the fixed plate 733 moves, it will cause the protruding rod 734 at its top to push the moving plate 6, thereby completing the purpose of adjusting the unfolding assembly.

[0055] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0056] Although the present invention 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.
