[0014]This invention uses a moving block to move a connecting block, causing the connecting block to disengage from the locking groove. Once the mounting rail is in the correct position, the moving block can be released, allowing the spring to elastically reset and push the connecting block back into the locking groove, thus securing the mounting rail. This locking structure allows for convenient movement and disassembly of the mounting rail without the need for additional tools, enabling workers to assemble and disassemble the rail more easily and efficiently. It also improves work efficiency and saves time. Furthermore, it addresses the issue that installing larger electronic components often requires two mounting rails, necessitating the removal of bolts, readjustment of the rails, and reinstallation – a cumbersome process requiring tools and wasting time and reducing efficiency.

[0003] In existing technology, a distribution cabinet can house all electronic components, such as protective relays, measuring instruments, signal indicators, busbars, connectors, and auxiliary components, within a single metal cabinet, forming a complete power distribution device. When installing these electronic components, they are typically first fixed to mounting rails, which are then connected to the cabinet using bolts. While bolt connections effectively secure the mounting rails within the distribution cabinet, some larger electronic components often require two mounting rails to be installed. This necessitates removing the bolts, readjusting the mounting rail positions, and reinstalling the components. This disassembly and reassembly process is cumbersome and requires tools, wasting time and reducing labor efficiency. Utility Model Content

[0022] 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 scope of protection of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses a low-voltage distribution cabinet. (Refer to...) Figure 1 and Figure 2 A low-voltage distribution cabinet includes a distribution cabinet body 1, an installation guide rail 2 is provided in the inner cavity of the distribution cabinet body 1, and a snap-fit structure 3 is provided on one side of the installation guide rail 2.
[0025] The snap-fit structure 3 includes a snap-fit strip 301. One side of the snap-fit strip 301 is fixedly connected to the inner cavity of the power distribution cabinet body 1. A snap-fit groove 309 is provided on one side of the snap-fit strip 301. A U-shaped plate 302 is provided on one side of the snap-fit strip 301. An installation block 308 is movably snapped onto one side of the U-shaped plate 302. One side of the installation block 308 is fixedly connected to one side of the installation guide rail 2. One side of the U-shaped plate 302 is slidably connected to the inner cavity of the power distribution cabinet body 1. An installation plate 303 is fixedly connected to one side of the U-shaped plate 302. A spring 304 is fixedly connected to one side of the installation plate 303. A connecting block 305 is fixedly connected to one end of the spring 304. The surface of the connecting block 305 is movably snapped into the inner cavity of the snap-fit groove 309. A moving block 306 is fixedly connected to one side of the connecting block 305. The surface of the moving block 306 is slidably connected to the inner cavity of the U-shaped plate 302. An auxiliary component 307 is provided on one side of the U-shaped plate 302.
[0026] The main body of the distribution cabinet 1 can be installed in a metal cabinet according to a certain electrical wiring scheme. The relevant primary equipment, such as circuit breakers, disconnect switches, load switches and secondary equipment, such as protective relays, measuring instruments, signal indicators and electronic components such as busbars, connectors and auxiliary parts, are all installed in a metal cabinet to form a complete power distribution device. At the same time, the main body of the distribution cabinet 1 is the prior art in this field, so it will not be described in detail here.
[0027] In addition, the guide rail 2 provides installation and connection for the electronic components inside the distribution cabinet body 1. The snap-fit strip 301 is connected to the distribution cabinet body 1, and the U-shaped plate 302 provides a connection for the spring 304 through its connection with the mounting plate 303. The spring 304 is connected to the connecting block 305, and the spring 304 can push the connecting block 305 through its own elasticity. By opening a snap-fit groove 309 on one side of the snap-fit strip 301, the snap-fit strip 301 can be connected to the connecting block 305. At the same time, when the connecting block 305 is pushed by the spring 304, it will snap into the inside of the snap-fit groove 309. The connecting block 305 is connected to the moving block 306, and the operator can push the moving block 306. When the moving block 306 is pushed, it will slide along the inner cavity of the U-shaped plate 302. Simultaneously, the connecting block 305 is moved, causing it to disengage from the snap-fit groove 309. The mounting block 308 provides a connection to the mounting guide rail 2 through its connection with the U-shaped plate 302. After the connecting block 305 disengages from the snap-fit groove 309, the operator can continue to push the connecting block 305 and move the mounting guide rail 2. When it reaches the appropriate position, the moving block 306 can be released. At this time, the spring 304 will elastically reset and push the connecting block 305 back into the snap-fit groove 309, thus completing the fixation of the mounting guide rail 2. Subsequently, the operator can use the auxiliary component 307 to strengthen the fixation of the mounting guide rail 2. Multiple snap-fit structures 3 are provided, and the multiple snap-fit structures 3 have the same structure, so they will not be described in detail here.
[0028] Reference Figure 3 and Figure 4 The auxiliary component 307 includes a plug hole 3071, which is located on one side of the snap-fit strip 301 and the U-shaped plate 302. Multiple plug holes 3071 are provided. One of the plug holes 3071 has a plug rod 3072 that is movably engaged in the inner cavity of the plug hole 3071. When the operator moves the installation guide rail 2 to a suitable position, the plug hole 3071 on the side of the U-shaped plate 302 can be aligned with the plug hole 3071 on the side of the snap-fit strip 301. Then, the plug rod 3072 is inserted into the interior of the plug hole 3071, so that the plug rod 3072 and the plug hole 3071 are engaged with each other, and the U-shaped plate 302 is fixed, making it less likely for the U-shaped plate 302 to slip or shift.
[0029] Reference Figure 5The inner cavity of the power distribution cabinet body 1 is provided with a first limiting groove 4. A first limiting block 5 is fixedly connected to one side of the U-shaped plate 302. The surface of the first limiting block 5 is slidably connected to the inner cavity of the first limiting groove 4. The U-shaped plate 302 can provide installation and connection for the first limiting block 5. By opening the first limiting groove 4 in the inner cavity of the power distribution cabinet body 1, the first limiting block 5 can slide in the inner cavity of the first limiting groove 4, so that when the U-shaped plate 302 moves, it can move more smoothly and stably.
[0030] Reference Figure 5 The inner cavity of the power distribution cabinet body 1 is provided with a sliding groove 6. A slider 7 is fixedly connected to one side of the first limiting block 5. The surface of the slider 7 is slidably connected to the inner cavity of the sliding groove 6. The first limiting groove 4 and the sliding groove 6 are interconnected. At the same time, the first limiting block 5 can provide installation and connection for the slider 7. The slider 7 is connected to the sliding groove 6. The setting of the slider 7 can further enhance the stability of the U-shaped plate 302, so that the U-shaped plate 302 can be used more smoothly.
[0031] Reference Figure 3 and Figure 5 A limiting rod 13 is fixedly connected to one side of the mounting plate 303, and a mounting groove 12 is provided on one side of the moving block 306. The surface of the limiting rod 13 is slidably connected to the inner cavity of the mounting groove 12. The mounting plate 303 can provide installation and connection for the limiting rod 13. By opening the mounting groove 12 on one side of the moving block 306, the limiting rod 13 can slide in the inner cavity of the mounting groove 12. The setting of the limiting rod 13 makes it difficult to detect deformation when the spring 304 performs elastic reset, so that the connecting block 305 and the snap-fit groove 309 cannot be snapped together, thus affecting the normal use of the snap-fit structure 3.
[0032] Reference Figure 2 and Figure 5 A snap-fit block 10 is fixedly connected to one side of the mounting block 308, and a connecting groove 11 is provided on one side of the U-shaped plate 302. The surface of the snap-fit block 10 is movably snapped into the inner cavity of the connecting groove 11. The mounting block 308 can provide installation and connection for the snap-fit block 10. By providing a connecting groove 11 on one side of the U-shaped plate 302, the snap-fit block 10 and the connecting groove 11 can be snapped into each other. The snap-fit block 10 can make it easier and more convenient for workers to install and disassemble the mounting guide rail 2.
[0033] Reference Figure 5The surface of the power distribution cabinet body 1 is provided with a second limiting groove 8. A second limiting block 9 is fixedly connected to one side of the mounting plate 303. The surface of the second limiting block 9 is slidably connected to the inner cavity of the second limiting groove 8. The mounting plate 303 is connected to the second limiting block 9. At the same time, the second limiting block 9 can be connected to the second limiting groove 8. The connection between the second limiting block 9 and the second limiting groove 8 can make the mounting plate 303 more stable when it moves and less prone to displacement.
[0034] Working Principle: Before use, the operator can first attach the mounting block 308 to one side of the U-shaped plate 302, and then push the moving block 306. When the moving block 306 is pushed, it will slide along the inner cavity of the U-shaped plate 302, simultaneously moving the connecting block 305 and causing it to disengage from the locking groove 309. After the connecting block 305 disengages from the locking groove 309, the operator can continue to push the connecting block 305, which in turn moves the mounting guide rail 2 through the U-shaped plate 302. When it reaches the appropriate position, the moving block 306 can be released. At this time, the spring 304 will elastically reset and push the connecting block 305 back into the locking groove 309, completing the mounting process. After securing the guide rail 2, the worker aligns the insertion hole 3071 on one side of the U-shaped plate 302 with the insertion hole 3071 on the other side of the snap-fit strip 301, and then inserts the insertion rod 3072 into the insertion hole 3071. This snaps the insertion rod 3072 into the insertion hole 3071, securing the U-shaped plate 302 and preventing it from slipping or shifting. The snap-fit structure 3 allows for easy movement and disassembly of the guide rail 2 without the need for other tools, making it easier and more efficient to install and remove the guide rail 2, thus improving work efficiency and saving time.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
