[0001] This utility model belongs to the field of power distribution equipment technology, and in particular relates to a linkage-type low-voltage switchgear. Background Technology

[0002] Interlocking low-voltage switchgear is a type of power distribution equipment used in power systems. It integrates multiple functional modules to achieve centralized control and protection of the power system. This type of switchgear typically consists of multiple low-voltage switchgear units, which, through internal electrical connections and control devices, achieve interlocking control of multiple circuits. It is characterized by high reliability, integrity, intelligence, flexibility, and safety, and is widely used in power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, and residential communities for the control, protection, and monitoring of power systems.

[0003] A search revealed that publication number CN221150572U, with an application date of November 10, 2023, discloses a low-voltage switchgear with high safety, including a low-voltage switchgear body. The opening of the low-voltage switchgear body is provided with an anti-wear component, and a labor-saving component is provided below the low-voltage switchgear body. The anti-wear component includes a fixed shell, with screws passing through the upper and lower ends of the fixed shell, and a spring connected to the inner side of the fixed shell.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. In the existing linkage-type low-voltage switchgear, the frame for installing components is mostly installed with bolts. This method is cumbersome, time-consuming and labor-intensive for workers to adjust the position of the frame, resulting in low work efficiency.

[0006] 2. Existing interlocking low-voltage switchgear achieves stable support of the cabinet by adjusting the position of the support plate using labor-saving components. However, this method requires turning the handle multiple times, which is cumbersome, time-consuming, and labor-intensive, resulting in low work efficiency. Therefore, we provide an interlocking low-voltage switchgear to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a linkage-type low-voltage switchgear. By setting up installation components, it is easy for operators to quickly adjust the position of the adjustment frame according to the size of the components, saving time and effort and increasing work efficiency. Furthermore, by using storage components and limiting components, it is easy for operators to quickly adjust the movement mode or stable support mode of the cabinet, reducing operation time and improving work efficiency.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a linkage-type low-voltage switchgear, including a cabinet and support legs welded to the four corners at the bottom. An installation frame is installed inside the cabinet, and an adjustment frame is installed on the surface of the installation frame from top to bottom. Both ends of the adjustment frame are provided with installation components. A storage component is provided at the bottom of the cabinet, and a limit component is provided at the bottom of one side wall of the cabinet.

[0010] The mounting components include a pressure plate located in front of the adjustment frame and a connecting rod fixed at the center of the rear end face of the pressure plate; the storage components include a T-shaped plate located below the cabinet and connecting brackets that are hinged to both ends of the T-shaped plate; the limiting components include an L-shaped plate that is slidably mounted on one side wall of the cabinet and a sliding plate fixed to the top of the front and rear end faces of the L-shaped plate.

[0011] The present invention is further configured such that the mounting bracket has insertion holes arranged in an array from top to bottom, and hook plates are fixed at both ends of the rear end face of the adjustment bracket, and the hook plates are slidably mounted on the outer wall of the mounting bracket.

[0012] The present invention is further configured such that the other end of the connecting rod slides through the sliding hole on the adjusting frame and connects to the moving plate, and one end of the front end face of the moving plate is fixedly provided with a plug, which is inserted into the adjacent plug hole.

[0013] The present invention is further configured such that a tension spring is sleeved on the outer wall of the connecting rod, and the two ends of the tension spring are respectively fixed on the rear end face of the adjusting frame and the front end face of the moving plate.

Detailed Implementation

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1 to 4 This utility model is a linkage-type low-voltage switchgear, including a cabinet 100 and support legs 101 welded to the four corners at the bottom. A mounting frame 102 is installed inside the cabinet 100. An adjustment frame 103 is installed on the surface of the mounting frame 102 from top to bottom. Both ends of the adjustment frame 103 are provided with mounting components 200. The mounting component 200 includes a pressure plate 201 set in front of the adjustment frame 103 and a connecting rod 202 fixed at the center of the rear end face of the pressure plate 201.

[0033] Specifically, the mounting bracket 102 has insertion holes 102a arranged from top to bottom. The rear end face of the adjusting bracket 103 is fixed with hook plates 103a at both ends, and the hook plates 103a are slidably mounted on the outer wall of the mounting bracket 102. The other end of the connecting rod 202 slides through the sliding hole on the adjusting bracket 103 and connects with the moving plate 203. One end of the front end face of the moving plate 203 is fixed with a post 204, which is inserted into the adjacent insertion hole 102a. A tension spring 202a is sleeved on the outer wall of the connecting rod 202, and the two ends of the tension spring 202a are fixed on the rear end face of the adjusting bracket 103 and the front end face of the moving plate 203, respectively.

[0034] Furthermore, during movement, the support leg 101 is at a distance from the ground and does not contact it. During support, the support leg 101 contacts the ground and plays a major supporting role. The connecting rod 202 connects the pressure plate 201 and the moving plate 203, playing a connecting and transmission role. The hook plate 103a limits the adjustment frame 103 and also plays an auxiliary sliding role. The diameter of the insertion post 204 is smaller than the diameter of the insertion hole 102a. Under the elastic action of the tension spring 202a, it can move the moving plate 203.

[0035] The operation process of this embodiment is as follows: Various components are installed on the adjustment frame 103. When it is necessary to install components of different sizes, the pressure plate 201 is pressed inward. The rear end face of the pressure plate 201 is connected to the moving plate 203 through the connecting rod 202. Therefore, the pressure plate 201 moves, and the moving plate 203 and the insertion post 204 move through the connecting rod 202, and the tension spring 202a is stretched. At this time, the insertion post 204 moves out of the insertion hole 102a, releasing the limiting effect on the adjustment frame 103. Then, under the action of the hook plate 103a, the position of the adjustment frame 103 is adjusted up and down along the outer wall of the mounting frame 102. After the position adjustment is completed, the force applied to the pressure plate 201 is stopped. At this time, under the elastic action of the tension spring 202a, the moving plate 203 is bounced back, so that the insertion post 204 is inserted into the adjacent insertion hole 102a, limiting the adjustment frame 103. This makes it easier for the staff to quickly adjust the position of the adjustment frame 103 according to the size of the components, saving time and effort and increasing work efficiency.

[0036] Example 2

[0037] Please see Figure 2 , Figure 5 and Figure 6 Based on Embodiment 1, unlike the first embodiment, a storage component 300 and a limiting component 400 are provided. The storage component 300 includes a T-shaped plate 301 disposed below the cabinet 100, and connecting brackets 302 that are hinged to be movably installed at both ends of the T-shaped plate 301. The limiting component 400 includes an L-shaped plate 401 that is slidably installed on one side wall of the cabinet 100, and a sliding plate 402 fixed to the top of the front and rear end faces of the L-shaped plate 401. This solves the problem that existing linkage-type low-voltage switchgear uses a labor-saving component to adjust the position of the support plate to achieve stable support of the cabinet during use. However, this method requires turning the handle multiple times, which is cumbersome, time-consuming, and labor-intensive, resulting in low work efficiency.

[0038] Specifically, a crossbar 303 is installed at the bottom of the connecting frame 302, and mounting seats 304 are installed at both ends of the crossbar 303; wheels 304a are movably installed inside the mounting seats 304, and the top of the mounting seats 304 is movably connected to the bottom of the cabinet 100 via a hinge; the sliding hole on the slide plate 402 is slidably fitted onto the outer wall of the guide rod 403, and the two ends of the guide rod 403 are fixed to the inner wall of the fixing frame 404; a spring 403a is fitted onto the outer wall of the guide rod 403, and the spring 403a is located between the top of the slide plate 402 and the inner wall of the fixing frame 404.

[0039] Furthermore, the T-shaped plate 301 is tilted at 90 degrees, and the sliding plate 402 slides on the outer wall of the guide rod 403, which guides and assists the sliding of the L-shaped plate 401. Under the elastic action of the spring 403a, it can move the L-shaped plate 401. The spring 403a can be removed according to the actual use. The mounting base 304 can only rotate in the direction close to the vertical section of the T-shaped plate 301, and is limited on the other side and cannot rotate.

[0040] The operation process of this embodiment is as follows: During the movement and transportation of the cabinet 100, the position of the cabinet 100 is adjusted by the wheels 304a. At this time, the T-shaped plate 301 is located inside the L-shaped plate 401, and the T-shaped plate 301 is limited by the L-shaped plate 401. When the cabinet 100 moves to the installation area, the worker pushes the L-shaped plate 401 upward. The L-shaped plate 401 moves upward under the limiting sliding action of the sliding plate 402 and the guide rod 403, and squeezes the spring 403a. At this time, the L-shaped plate 401 releases its limiting effect on the T-shaped plate 301. Then, the worker applies force to the cabinet 100, causing it to tilt to one side (towards the opposite direction of the protruding end of the T-shaped plate 301). Since the top of the mounting base 304 is movably installed at the bottom of the cabinet 100, and the mounting base 304 is connected by the crossbar 303 and the connecting frame... 302 is also movably connected to the T-shaped plate 301. Therefore, when the cabinet 100 is tilted, the mounting base 304 tilts in the opposite direction under the action of the hinge, causing the wheel 304a to make an arc motion and retract. As the wheel 304a rotates and retracts, the support leg 101 will contact the ground and provide support for the cabinet 100, ensuring the stability of the cabinet 100 after installation. Similarly, when the cabinet 100 needs to be moved, the staff pushes the T-shaped plate 301 inward and pushes the cabinet 100 in the opposite direction, lifting the wheel 304a to hold the cabinet 100. At this time, the support leg 101 is away from the ground. Then, the force applied to the L-shaped plate 401 is stopped. At this time, under the elastic action of the spring 403a, the L-shaped plate 401 is popped out to limit the end of the T-shaped plate 301, thus limiting the wheel 304a.
