Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet mounting base technology, and more particularly to a power distribution cabinet mounting base and a power distribution cabinet. Background Technology

[0002] The mounting bases of existing distribution cabinets are usually welded and fixed to the cabinet body, and there is no function to adjust the installation angle of the distribution cabinet. This makes it impossible to adjust the angle of the distribution cabinet according to the on-site installation environment during and after installation. As a result, in some narrow spaces or with special installation requirements, reinstallation is required. Alternatively, distribution cabinets with horizontal mounting bases are only suitable for installation on the ground, while those with vertical mounting bases are only suitable for installation on the wall. They cannot be installed on both the ground and the wall at the same time, which is quite limiting. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a power distribution cabinet mounting base and a power distribution cabinet, which solves the problem that the mounting base of the existing power distribution cabinet cannot adjust the installation angle of the power distribution cabinet.

[0004] The present invention provides a power distribution cabinet mounting base, including a connecting shaft, with fixed seats symmetrically arranged at both ends of the connecting shaft, the fixed seats being used to connect to the installation target of the power distribution cabinet;

[0005] The connecting shaft has an annular radial protrusion on its circumferential surface. A bushing is fitted around the outer circumference of the protrusion. The bushing is rotatably connected to the connecting shaft. An ear plate is fixedly connected to the outer circumference of the bushing, and the bushing passes through the ear plate.

[0006] The protrusion is provided with a plurality of first through holes, and the bushing is provided with a second through hole. The plurality of first through holes are distributed at intervals with the same axis of the connecting shaft as the center. The second through hole coincides with one of the first through holes.

[0007] The ear plate is provided with a fixing stud, which passes through one side of the ear plate along the axial direction of the second through hole and is threadedly connected to the ear plate. The other side of the ear plate is used to connect to the power distribution cabinet body.

[0008] The diameters of both the first through hole and the second through hole are not less than the diameter of the fixing stud.

[0009] Preferably, the connecting shaft and the bushing are provided with limit components to limit the single rotation angle of the connecting shaft.

[0010] More preferably, the number of the first through holes is two, and the central angle formed by the centers of the two first through holes is 90°.

[0011] More preferably, the limiting component specifically comprises:

[0012] Limiting blocks are provided on the surface of the connecting shaft;

[0013] The bushing has a first stop block and a second stop block on the end face on the same side as the limiting block, and the limiting block is located between the first stop block and the second stop block.

[0014] The end faces of both the first stop block and the limiting block are located on the same plane as the center of one of the first through holes;

[0015] Furthermore, the end face of the second stop block facing the first stop block is at 180° to the center of the other first through hole.

[0016] Preferably, the inner wall of the bushing is provided with a groove that matches the protrusion, and the protrusion is located in the groove;

[0017] The inner wall of the bushing is in clearance fit with the connecting shaft and the protrusion.

[0018] Preferably, a handwheel is provided at the end of the fixing stud away from the ear plate.

[0019] Preferably, the first through hole has a chamfered edge on the outer wall of the protrusion.

[0020] Preferably, the fixing base includes a connecting rod and a mounting plate, one end of the connecting rod is connected to the connecting shaft, and the other end is connected to the mounting plate.

[0021] More preferably, the fixing base further includes diagonal bracing plates symmetrically arranged on both sides of the connecting rod, one side of the diagonal bracing plate being connected to the connecting rod and the other side being connected to the mounting plate.

[0022] Preferably, the connecting shaft has two protrusions spaced axially at intervals.

[0023] More preferably, the axes of symmetry of the two protrusions coincide with the axes of symmetry of the fixing seats at both ends of the connecting shaft.

[0024] Another object of the present invention is to provide a power distribution cabinet, including a power distribution cabinet body and the aforementioned power distribution cabinet mounting base, wherein the power distribution cabinet mounting base is fixed to the bottom of the power distribution cabinet body.

[0025] As can be seen from the above technical solutions, the present invention has the following advantages:

[0026] This invention provides a power distribution cabinet mounting base. By rotatably connecting the bushing to the connecting shaft, the fixing seat fixed to the end of the connecting shaft can rotate. Multiple first through holes are provided on the protrusion, and a second through hole that coincides with the first through holes is provided on the bushing. When the connecting shaft is rotated to adjust the fixing seat to a suitable angle and align the second through hole with one of the first through holes, the end of the fixing stud penetrating one side of the ear plate is screwed into the first through hole. The engagement of the fixing stud end with the first through hole restricts the rotation of the connecting shaft, thereby fixing the connecting shaft and the fixing seat. This power distribution cabinet mounting base allows for adjustment of the power distribution cabinet installation angle and provides multiple angle adjustments to adapt to different installation environments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, unless otherwise expressly specified.

[0036] Embodiment 1 of the present invention provides a power distribution cabinet mounting base, such as Figures 1-3 As shown, it includes: a connecting shaft 1, with fixed seats 2 symmetrically arranged at both ends of the connecting shaft 1. The fixed seats 2 are used to connect to the installation target (such as the ground, wall, structural frame, etc.) of the distribution cabinet. Specifically, various connection methods can be used to reliably and securely connect the fixed seats 2 and the connecting shaft 1, such as welding the fixed seats 2 to the connecting shaft 1, or using bolts to facilitate the handling and replacement of parts. These methods will not be described in detail here.

[0037] A ring-shaped radial protrusion 3 is provided on the circumferential surface of the connecting shaft 1. A bushing 4 is fitted around the outer circumference of the protrusion 3. The bushing 4 is rotatably connected to the connecting shaft 1, that is, the connecting shaft 1 can rotate within the bushing 4 but remains axially fixed. Specifically, as shown in the figure... Figure 3 As shown, a groove 9 matching the protrusion 3 can be provided on the inner wall of the bushing 4. During assembly, the protrusion 3 is embedded in the groove 9, and the inner wall of the bushing 4, the connecting shaft 1, and the protrusion 3 are clearance-fitted, thereby achieving an axially fixed rotational connection between the bushing 4 and the connecting shaft 1. Of course, those skilled in the art, inspired by this structure, can also adopt other structural forms that enable the bushing 4 and the connecting shaft 1 to be rotatably connected, which will not be described in detail here.

[0038] The bushing 4 is fixedly connected to the lug 5 on its outer circumference, and the bushing 4 passes through the lug 5.

[0039] The protrusion 3 is provided with multiple first through holes 7, and the bushing 4 is provided with second through holes 8. The multiple first through holes 7 are distributed at intervals with the same axis as the connecting shaft 1 as the center, and the second through hole 8 coincides with one of the first through holes 7.

[0040] The ear plate 5 is provided with a fixing stud 6. The fixing stud 6 passes through one side of the ear plate 5 along the axial direction of the second through hole 8 and is threadedly connected to the ear plate 5. The other side of the ear plate 5 is used to connect to the power distribution cabinet 18.

[0041] The diameters of both the first through hole 7 and the second through hole 8 are not less than the diameter of the fixing stud 6.

[0042] The present invention provides a power distribution cabinet mounting base. By rotatably connecting the bushing 4 to the connecting shaft 1, the fixing seat 2 fixed to the end of the connecting shaft 1 can rotate. Multiple first through holes 7 are provided on the protrusion 3, and second through holes 8 that can coincide with the first through holes 7 are provided on the bushing 4. When the connecting shaft 1 is rotated to adjust the fixing seat 2 to a suitable angle and make the second through hole 8 coincide with one of the first through holes 7, the end of the fixing stud 6 penetrating one side of the ear plate 5 is screwed into the first through hole 7. The engagement of the fixing stud 6 end with the first through hole 7 restricts the rotation of the connecting shaft 1, thereby fixing the connecting shaft 1 and the fixing seat 2. The power distribution cabinet mounting base of the present invention allows for adjustment of the installation angle of the power distribution cabinet and can provide multiple angle adjustments to adapt to different installation environments.

[0043] It should be noted that when multiple first through holes 7 are distributed at intervals, the size of the central angle formed by adjacent first through holes 7 can be set according to the application scenario, and can be the same or different; the diameters of the first through holes 7 and the second through holes 8 should be the same as those of the fixing stud 6, while ensuring that the fixing stud 6 can enter smoothly, so as to avoid a significant gap between the diameter difference between them and the fixing stud 6, which would cause the connecting shaft 1 to rotate slightly. Specifically, the diameters of the first through holes 7 and the second through holes 8 should be the same and slightly larger than the diameter of the fixing stud 6 by 1 to 2 mm.

[0044] In one specific embodiment, a limiting component is provided on the connecting shaft 1 and the bushing 4 to limit the angle that the connecting shaft 1 can rotate at one time. When rotating the connecting shaft 1, the limiting component causes the connecting shaft 1 to stop rotating every time it reaches the angle where the first through hole 7 and the second through hole 8 coincide, avoiding the need for installers to make fine adjustments to align the first through hole 7 and the second through hole 8, and making angle adjustment faster.

[0045] In one specific embodiment, there are two first through holes 7, and the central angle formed by the centers of the two first through holes 7 is 90°. The adjustable angle of the distribution cabinet mounting base in this embodiment is 90°, which can adjust the fixing base 2 to a horizontal or vertical state to adapt to the situation where it needs to be fixed on the ground or wall. Compared with the distribution cabinet mounting base that cannot adjust the installation angle, it has less limitation of application and better practicality. Furthermore, a limiting block 10 is provided on the surface of the connecting shaft 1, and a first stop block 11 and a second stop block 12 are provided on the end face of the bushing 4 on the same side as the limiting block 10. The limiting block 10 is located between the first stop block 11 and the second stop block 12. The end faces of the first stop block 11 and the limiting block 10 are both on the same plane as the center of one of the first through holes 7. The end face of the second stop block 12 facing the first stop block 11 is 180° to the center of the other first through hole 7, so that the central angle between the first stop block 11 and the second stop block 12 is 90°. In this way, through the cooperation of the first stop block 11 and the second stop block 12, the first through hole 7 and the second through hole 8 can be aligned with only one angle adjustment, making the angle adjustment of the distribution cabinet mounting base more convenient.

[0046] In a more specific embodiment, a handwheel 13 is provided at the end of the fixing stud 6 away from the ear plate 5, so that the fixing stud 6 can be easily rotated by the handwheel 13.

[0047] In one specific embodiment, the first through hole 7 has a chamfer 14 on the edge of the outer wall of the protrusion 3 so that the fixing stud 6 can smoothly enter the first through hole 7, eliminating the inconvenience caused by machining, installation errors or insufficient rotation to align the first through hole 7 and the second through hole 8.

[0048] In one specific embodiment, the fixing base 2 includes a connecting rod 15 and a mounting plate 16. One end of the connecting rod 15 is connected to the connecting shaft 1, and the other end is connected to the mounting plate 16. More specifically, the fixing base 2 also includes diagonal bracing plates 17 symmetrically arranged on both sides of the connecting rod 15. One side of the diagonal bracing plate 17 is connected to the connecting rod 15, and the other side is connected to the mounting plate 16. The diagonal bracing plates 17 improve the stability of the connection between the connecting rod 15 and the mounting plate 16.

[0049] In one specific embodiment, there are two protrusions 3, which are spaced apart along the axial direction of the connecting shaft 1. This increases the number of ear plates 5, thereby increasing the stress points on the connecting rod 15 that bear the weight of the distribution cabinet, improving the bending resistance of the connecting rod 15, and preventing concentrated stress on the connecting rod 15. Furthermore, the axes of symmetry of the two protrusions 3 coincide with the axes of symmetry of the fixing seats 2 at both ends of the connecting shaft 1, ensuring that the distance between the ear plates 5 at both ends of the connecting shaft 1 and the fixing seats 2 is equal, so that the distribution cabinet mounting base in this embodiment is evenly stressed at both ends. It should be noted that the number of protrusions 3 can also be set to three, four, etc., which can be selected according to the weight of the distribution cabinet or the bottom width.

[0050] Embodiment 2 of the present invention provides a power distribution cabinet, such as Figure 1 As shown, it includes a power distribution cabinet body 18 and the aforementioned power distribution cabinet mounting base, which is fixed to the bottom of the power distribution cabinet body 18.

[0051] The second embodiment of the present invention provides a power distribution cabinet that can adjust the installation angle of the power distribution cabinet and can provide multiple angle adjustments to adapt to different installation environment needs.

[0052] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
