Description

Technical Field

[0001] This utility model relates to the field of power equipment installation technology, and in particular to a modular quick-disassembly and assembly power switch fixing bracket. Background Technology

[0002] Distribution switches are typically mounted on brackets inside control cabinets. Existing brackets are mostly welded for fixation, making post-installation repositioning difficult, incompatible with different switch sizes, and requiring complete bracket replacement for equipment upgrades, which is time-consuming and labor-intensive. While bolt fixing allows for disassembly, tightening bolts individually within a confined cabinet is inconvenient and inefficient, problems particularly pronounced in scenarios with frequent upgrades.

[0003] To address the aforementioned issues, a modular quick-assembly bracket is designed. By combining a plug-in main frame with an adjustable mounting base, tool-free rapid assembly is achieved, while a dual-locking structure ensures reliable connection. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies where brackets are usually fixed by welding or other methods, making it difficult to adjust their position once installed. Therefore, this utility model proposes a modular, quick-disassembly and assembly electrical switch fixing bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular quick-assembly and quick-disassembly mounting bracket for an electric switch includes a main frame, with multiple insertion holes at both ends of the side wall of the main frame.

[0007] Mounting bracket, the mounting bracket is located on the side wall of the main frame, and both ends of one side of the mounting bracket are slidably provided with plug rods, the plug rods are inserted into adjacent plug holes;

[0008] The mounting base includes an outer slide and an inner slide. The power distribution switch is mounted on the side wall of the outer slide. The two ends of the inner slide are slidably disposed inside the two ends of the outer slide. The outer slide and the inner slide are fitted onto the outer wall of the mounting frame. A tension spring is provided inside the outer slide, and the two ends of the tension spring are respectively connected to the inner wall of the outer slide and one end of the inner slide.

[0009] In one possible design, L-shaped inserts are fixedly installed at both ends of the sidewall of the main frame. Multiple L-shaped inserts and multiple sockets on the same side are arranged alternately, and the L-shaped inserts are located below the sockets. Slots are provided on both sides of the bottom of the mounting bracket, and one end of the L-shaped insert mates with the adjacent slot.

[0010] During installation, after the insertion rod is inserted into the insertion hole, the mounting bracket moves downward, allowing the L-shaped insertion strip to be inserted into the slot at the bottom of the mounting bracket for initial positioning; the outer and inner slides are reset and clamped by tension springs to achieve quick assembly and disassembly.

[0011] In one possible design, a sliding plate is slidably disposed inside the mounting bracket, and fixing rods are fixedly disposed at both ends of one side of the sliding plate. Fixing grooves are provided at both ends of the side wall of the main frame. Multiple fixing grooves located on the same side are respectively located on one side of multiple insertion holes. One end of the fixing rod slides through the mounting bracket and cooperates with the adjacent fixing groove on the same side.

[0012] In one possible design, a fixing strip is fixedly provided on one side of the slide plate, a through hole is provided on one side of the mounting bracket, one side of the fixing strip extends to the outside of the mounting bracket through the through hole, and a slot is provided on one side of both the outer slide and the inner slide, and the fixing strip cooperates with the slot.

[0013] In one possible design, the bottom of the mounting bracket is rotatably provided with a threaded rod, and the bottom of the slide plate is provided with a flange, with the flange threaded onto the outer wall of the threaded rod.

[0014] When the threaded rod is rotated, the sliding plate drives the fixing rod to insert into the fixing groove, and the fixing strip is inserted into the slot to achieve double locking.

[0015] In one possible design, a guide groove is provided on the side wall of the mounting bracket, and the insertion rod slides longitudinally along the guide groove.

[0016] In one possible design, the slot is formed on the opposite sidewalls of the outer slide and the inner slide.

[0017] In one possible design, the two ends of the tension spring are connected to the inner wall of the outer slide and one end of the inner slide, respectively, via hooks.

[0018] In this application, during actual use, the insertion rod is initially located at the bottom of the side of the mounting bracket. After inserting the insertion rod into the corresponding insertion hole, the mounting bracket is moved downwards so that the L-shaped insertion strip is inserted into the slot at the bottom of the mounting bracket, thus initially installing the mounting bracket. Then, the outer slide and inner slide are pulled apart to form an opening on one side, and then they are fitted onto the outer wall of the mounting bracket. The outer slide and inner slide are reset by internal tension springs, thus initially installing the mounting base. After the mounting bracket and multiple mounting bases on the surface are assembled, the threaded rod can be rotated. The threaded rod will drive the sliding plate to move, and the sliding plate will drive the fixing rod and fixing strip to move. One end of the fixing rod will be inserted into the inside of the fixing groove, thus further fixing the main frame and the mounting bracket. The fixing strip will be inserted into the inside of the slot, so that the outer slide and inner slide cannot move relative to each other, thus fixing the mounting bracket and the mounting base. The power distribution switch is installed on the surface of the outer slide in the mounting base by bolts or other means.

[0019] In this utility model, the modular quick-disassembly and assembly power switch fixing bracket, through modular design, enables the main frame and mounting bracket, as well as the mounting bracket and mounting base, to be quickly installed and subsequently replaced and disassembled.

[0020] In this utility model, the modular quick-disassembly and assembly electric switch fixing bracket, through the threaded rod, enables the locking mechanism of the components to be rotated by it, without the need for additional tools, and can meet the required quick operation.

[0021] In this utility model, the modular structure design effectively solves the technical problems of poor adaptability and high maintenance cost of traditional power distribution switch brackets. The mounting bracket can be quickly inserted and positioned at any position along the longitudinal direction of the main frame, and the mounting base adopts a split sliding base structure, which can achieve the effect of quick disassembly and position adjustment.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In one embodiment: Refer to Figure 1-2 A fixed bracket includes: a main frame 1, a mounting bracket 2, and a mounting base 3.

[0031] Reference Figure 3-4 The main frame 1 is a rectangular frame structure, with multiple insertion holes 7 evenly spaced longitudinally at both ends of its two side walls, and L-shaped insertion strips 6 alternately arranged between adjacent insertion holes 7. Fixing grooves 14 are also provided at both ends of the side walls of the main frame 1, with a corresponding fixing groove 14 provided next to each insertion hole 7 for cooperating with the locking mechanism of the mounting bracket 2.

[0032] Mounting bracket 2 is a long, narrow steel structure with slots 9 on both sides of its bottom. The slots 9 match one end of the L-shaped insert 6. Two insert rods 8 are slidably mounted on the side wall of mounting bracket 2. In the initial state, the insert rods 8 are located at the bottom of the side wall of mounting bracket 2. During installation, the insert rods 8 are aligned with the insertion holes 7 on the side wall of the main frame 1 and inserted. Then, the mounting bracket 2 is pressed down so that one end of the L-shaped insert 6 is fully inserted into the slot 9, achieving the initial positioning of mounting bracket 2.

[0033] Reference Figure 5-6 The mounting base 3 consists of an outer slide 4 and an inner slide 5, both of which are U-shaped. The two ends of the inner slide 5 are respectively embedded in the grooves at both ends of the outer slide 4 to form a sliding connection. A tension spring is installed between the outer slide 4 and the inner slide 5. The two ends of the tension spring are connected to the inner wall of the outer slide 4 and the end of the inner slide 5 respectively via hooks, ensuring that both tend to contract towards the center. After the outer slide 4 and the inner slide 5 are pulled outwards to form an opening, they are fitted onto the outer wall of the mounting frame 2. Upon release, the tension spring drives both to return to their original position and automatically clamp the mounting frame 2, thus completing the fixation of the mounting base 3.

[0034] The mounting bracket 2 has a sliding plate 11 inside, with fixing rods 12 fixedly connected to both sides of the sliding plate 11. The ends of the fixing rods 12 penetrate the side wall of the mounting bracket 2 and correspond to the fixing grooves 14. A threaded rod 15 is threadedly connected to the bottom edge of the sliding plate 11, and the end of the threaded rod 15 is rotatably connected to the bottom of the mounting bracket 2 through a bearing. A fixing strip 13 is also fixedly installed on the surface of the sliding plate 11, and a through hole 10 is opened in the side wall of the mounting bracket 2 to expose the fixing strip 13. When the threaded rod 15 is rotated, the sliding plate 11 drives the fixing rod 12 to move laterally, so that the end of the fixing rod 12 is inserted into the fixing groove 14, realizing a rigid connection between the main frame 1 and the mounting bracket 2; at the same time, the fixing strip 13 passes through the through hole 10 and is inserted into the slot 16 of the outer slide 4 and the inner slide 5, preventing them from sliding relative to each other, thus completing the final locking of the mounting base 3.

[0035] This application can be used in the field of power equipment installation, or in other fields applicable to this application.

[0036] In another embodiment: Reference Figure 5 A modular, quick-disassembly and assembly power switch fixing bracket is applied to the field of power equipment installation. The outer slide 4 has threaded holes on its side wall, and the power switch is directly fixed to the surface of the outer slide 4 by bolts.

[0037] The mounting bracket 2 has a guide groove on its side wall, and the insertion rod 8 slides longitudinally along the guide groove to ensure insertion accuracy.

[0038] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
