Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinets, and in particular to a quick-assembly and disassembly structure for power distribution cabinets. Background Technology

[0002] The distribution cabinet has symmetrically arranged support bars. The guide rails can be fixed to the two support bars with bolts. Electrical components such as PLC controllers and circuit breakers are clipped onto the guide rails. Depending on the design of the distribution cabinet, the number and spacing of the guide rails vary. Usually, multiple guide rails are arranged from top to bottom. All of them are installed with bolts, which increases the number of operation steps for electricians when wiring and assembling, and also makes disassembly and assembly troublesome during subsequent maintenance. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a quick-assembly and disassembly structure for power distribution cabinets, solving the problem of cumbersome disassembly and assembly of guide rails in traditional power distribution cabinets.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A quick-assembly and disassembly structure for a power distribution cabinet includes a cabinet body, wherein two guide rail frames are symmetrically fixed between the top plate and the bottom plate of the cabinet body, and the guide rails are inserted and installed on the two guide rail frames from top to bottom.

[0006] The inner wall of the cabinet's back panel is slidably connected with a locking strip. All guide rails are mounted on the guide rail frame. The locking strip is pushed close to the guide rail by the translation component. The locking strip can simultaneously insert into all guide rails in the horizontal direction, thus restricting the longitudinal degree of freedom of the guide rails.

[0007] Optionally, the guide rail frame has multiple slots at equal intervals from top to bottom, and both ends of the guide rail are symmetrically formed with locking strips. The locking strips are arranged in an inverted L shape and protrude from the back of the guide rail. When the guide rail is installed, the locking strips pass through the slots on the guide rail frame on both sides. In the installed state, the guide rail frame is locked between the guide rail and the locking strips.

[0008] Optionally, both the upper and lower ends of the locking strip are formed with sliding connecting parts that bend horizontally toward one side of the back plate. Support members are symmetrically fixed on the inner wall of the back plate. The grooves on the two support members are arranged opposite to each other. The two sliding connecting parts are slidably inserted into the grooves on the two support members respectively. Two reinforcing grooves are symmetrically formed on the outer wall of the locking strip. The extension path of the reinforcing grooves is the same as the length direction of the locking strip.

[0009] Optionally, the locking bar includes a plurality of locking pins fixed at equal intervals from top to bottom, the spacing between the locking pins being the same as the spacing between the slots, a locking groove being formed in the middle of the guide rail, and the locking pins facing the locking groove when the guide rail is in the installation state.

[0010] Optionally, the translation component includes a bolt threadedly connected to the middle of the back plate through a threaded hole. The bolt axis is perpendicular to the inner and outer walls of the back plate. The bolt passes through the back plate and is rotatably connected to the outer wall of the locking strip. A recessed groove protruding into the inner side of the cabinet is formed in the middle of the back plate, and the end of the bolt away from the locking strip is located in the recessed groove.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] Compared to the cumbersome method in traditional distribution cabinets where each guide rail needs to be secured to the support bar with multiple bolts one by one, this utility model adopts a design that combines "pre-insertion positioning" and "linkage locking". During installation, the worker only needs to align the inverted L-shaped locking strips at both ends of the guide rail with the corresponding slots on the guide rail frame, insert them and lower them to achieve the initial positioning and suspension of the guide rail. Then, only a single bolt needs to be rotated to push the locking strip, which can simultaneously restrict the longitudinal degree of freedom of all guide rails, simplifying the traditional operation of tightening each bolt one by one and greatly improving the efficiency of assembly and maintenance.

[0020] 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.

[0021] Please see Figures 1 to 6This embodiment provides a quick-assembly and disassembly structure for a power distribution cabinet, including a cabinet body 1. Two guide rail frames 2 are symmetrically fixed between the top plate 101 and the bottom plate 102 of the cabinet body 1. The guide rail frames 2 have multiple slots 201 evenly spaced from top to bottom. The guide rail frames 2 are used to install guide rails 3. Both ends of the guide rails 3 are symmetrically formed with engaging strips 301. The engaging strips 301 are arranged in an inverted L-shape and protrude from the back of the guide rails 3. When pre-installing the guide rails 3, the assembly... The worker holds the guide rail 3 and aligns the locking strips 301 at both ends with the two slots 201 at the same height on the guide rail frame 2 at both ends. The locking strips 301 are passed through the slots 201 to the back of the guide rail frame 2. Then the worker slowly lowers the guide rail 3 so that the top surface of the inner wall of the locking strip 301 abuts against the bottom surface of the slot 201. The locking strips 301 fix the guide rail 3 on the guide rail frame 2. The guide rail 3 is in the installed state. In this state, the guide rail 3 can be freely installed and removed from the guide rail frame 2.

[0022] The inner wall of the back panel 103 of the cabinet 1 is provided with a locking strip 4. Both the upper and lower ends of the locking strip 4 are formed with sliding connection parts 401 that bend horizontally to one side of the back panel 103. The outer wall of the locking strip 4 is symmetrically formed with two reinforcing grooves 402. The extension path of the reinforcing grooves 402 is the same as the length direction of the locking strip 4. The reinforcing grooves 402 can improve the structural strength of the locking strip 4, making it less likely to be bent.

[0023] Two support members 5 are symmetrically fixed on the inner wall of the back plate 103. Grooves 501 are formed on the opposite sides of the two support members 5. The upper and lower sliding connecting parts 401 are respectively slidably inserted into the two grooves 501 to realize the sliding installation between the locking strip 4 and the back plate 103. After the locking strip 4 is installed on the support member 5, it can slide towards or away from the guide rail 3.

[0024] On the side of the locking bar 4 near the guide rail 3, multiple locking pins 6 are fixed at equal intervals from top to bottom. The spacing between the locking pins 6 is the same as the spacing between the slots 201. A locking groove 7 is formed in the middle of the guide rail 3. When the guide rail 3 is in the installation state, the locking pins 6 are directly opposite the locking groove 7.

[0025] A bolt 8 is threadedly connected to the middle of the back panel 103 through a threaded hole. The axis of the bolt 8 is perpendicular to the inner and outer walls of the back panel 103. The bolt 8 passes through the back panel 103 and is rotatably connected to the outer wall of the locking strip 4. A recessed groove 1031 protruding into the cabinet 1 is formed in the middle of the back panel 103. The end of the bolt 8 away from the locking strip 4 is located in the recessed groove 1031, which can prevent the bolt 8 from protruding on the surface of the outer wall of the back panel 103.

[0026] By rotating bolt 8, it moves along the threaded hole to one side of guide rail 3, pushing locking strip 4 closer to guide rail 3. Then, locking pin 6 inserts into locking groove 7, locking guide rail 3 and preventing it from moving longitudinally. This achieves a one-step operation, simultaneously positioning all guide rails 3 without requiring each guide rail 3 to be bolted individually. The same principle applies to subsequent maintenance and disassembly, enabling quick assembly and disassembly of guide rails 3, reducing operational steps, and significantly improving assembly and disassembly efficiency.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
