Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically to a quick-installation structure for electrical components inside an electrical cabinet. Background Technology

[0002] In existing technologies, the installation method for electrical components (such as residual current devices, circuit breakers, contactors, relays, etc.) inside electrical cabinets is generally as follows: a flexible snap-fit ​​structure is installed on the component itself, and the snap-fit ​​structure cooperates with the rails inside the electrical cabinet to achieve installation and fixation. However, this flexible snap-fit ​​structure is usually located on the component itself, resulting in a complex structure and high manufacturing cost. Furthermore, the flexible snap-fit ​​requires significant operating force during installation and disassembly, making it laborious and inconvenient for quick installation, disassembly, maintenance, and replacement in confined spaces, causing inconvenience to on-site construction.

[0003] Therefore, there is an urgent need to provide a quick-installation structure for electrical components that is simple in structure, low in cost, and easy to install and disassemble, in order to overcome the above-mentioned shortcomings. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] Please see Figures 1-3 A quick-installation structure for electrical components inside an electrical cabinet includes electrical components 1 and rails 2. Several rails 2 are arranged in a straight line and installed inside the electrical cabinet to support the electrical components 1. Figure 1 As shown, the front of the rail 2 is recessed to form a groove 3. At least two transverse grooves 4 are opened on the groove 3. The mounting bolts pass through the transverse grooves 4 and are screwed onto the electrical cabinet, thereby firmly fixing the position of the rail 2 inside the electrical cabinet. At the same time, the structure of the groove 3 facilitates the tight fit between the rail 2 and the electrical cabinet, improving the installation stability.

[0027] like Figure 2 As shown, a card plate 5 is fixedly installed on the back of the electrical component 1, and a protrusion 6 is formed on the top of the card plate 5.

[0028] In addition, a support plate 7 is fixedly provided at the bottom of the front side of the rail 2 to support the clamping plate 5 on the electrical component 1, support the weight of the electrical component 1, and ensure the stable positioning of the electrical component 1; a pressure plate 8 is movably provided at the top of the front side of the rail 2 to press the clamping plate 5; furthermore, an embedded part 9 that cooperates with the protrusion 6 is also provided at the bottom of the pressure plate 8.

[0029] When the clamping plate 5 is inserted into the rail 2, the clamping plate 5 is located between the support plate 7 and the pressure plate 8. The protrusion 6 is precisely embedded in the embedding part 9 at the bottom of the pressure plate 8, thereby effectively preventing the clamping plate 5 from falling off and thus firmly fixing the position of the electrical component 1 (the clamping plate 5 can slide along the length of the rail 2).

[0030] In this embodiment, to facilitate quick assembly, the protrusion 6 is designed as a right-angled triangular block with its inclined surface facing away from the electrical component 1, so as to smoothly enter the embedding part 9 of the pressure plate 8; at the same time, a front slope 10 is formed at the front end of the bottom of the pressure plate 8 to reduce the resistance when the protrusion 6 enters.

[0031] Furthermore, the top of the pressure plate 8 is connected to the movable plate 12 via the column 11. The movable plate 12 is movably disposed inside the adjustment box 13, and a spring 14 is fixedly disposed between it and the inner top wall of the adjustment box 13.

[0032] When installing electrical component 1, simply insert the clamping plate 5 directly between the support plate 7 and the pressure plate 8. When the protrusion 6 contacts the front slope surface 10, the protrusion 6 pushes the pressure plate 8 upward, and the column 11 and the movable plate 12 then compress the spring 14. When the protrusion 6 reaches the position corresponding to the embedded part 9, under the elastic force of the spring 14, the pressure plate 8 automatically moves downward, precisely fitting the protrusion 6, thus completing the fixing of electrical component 1. This structure greatly simplifies the installation process, eliminating the need for a complex elastic buckle structure in electrical component 1 itself, thereby significantly reducing the manufacturing cost of electrical component 1.

[0033] Therefore, in this embodiment, by setting a support plate 7 and a pressure plate 8 on the rail 2 and cooperating with a clamping plate 5, the electrical component 1 can be fixed without setting its own elastic buckle structure, which greatly simplifies the structure of the electrical component 1 body and reduces the production and manufacturing cost.

[0034] like Figure 3 As shown, an inner cavity is formed inside the rail 2. A lead screw 15 is rotatably installed inside the inner cavity. One end of the lead screw 15 is rotatably installed on the inner wall of the inner cavity, and the other end extends to the outside of the inner cavity and is fixedly connected to a knob 18. A lead screw nut 16 is screwed to the outer wall of the lead screw 15. The lead screw nut 16 is fixedly connected to the adjustment box 13 through a connecting plate 17.

[0035] Turning the screw 15 by the knob 18 allows the screw nut 16 to move up and down. The up and down movement of the screw nut 16, through the connecting plate 17, drives the adjusting box 13 and the pressure plate 8 to move up and down. When the pressure plate 8 moves up, the clamping and positioning of the clamping plate 5 can be released, thus facilitating the disassembly of the electrical component 1 for subsequent maintenance and replacement.

[0036] In this embodiment, electrical component 1 can be a commonly used electrical component such as a leakage current protector, contactor, air switch, intermediate relay, terminal block, switching power supply, frequency converter or servo driver.

[0037] In summary, this embodiment, through the cooperation of rail 2, support plate 7, pressure plate 8 and clamping plate 5, and combined with the design of the lead screw 15 adjustment mechanism, realizes the rapid installation and disassembly of electrical component 1, greatly reduces the labor intensity of operators, effectively improves on-site operation efficiency, and reduces equipment maintenance costs.

[0038] 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.
