[0018] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0019] According to one embodiment of the present invention, Figure 1-Figure 3 Shown.

[0020] For the main structure of the switch cabinet in the present application, a shock-absorbing switch cabinet for high-power equipment includes: a cabinet body 1, a frame 2 for installing external electrical components is fixed on the inner wall of the cabinet body 1, the bottom of the frame 2 is covered with an outer bottom frame 3, and a plurality of groups of shock-absorbing components 4 arranged in parallel are arranged at the bottom of the outer bottom frame 3. The shock-absorbing components 4 include at least two groups and are symmetrically arranged around the center of the outer bottom frame 3. Each of the shock-absorbing components 4 includes a bottom plate 41, heightened steels 42 fixed at both ends of the bottom plate 41 in parallel and at intervals, and vertically fixed to each heightened steel The vertical steels 43 and the shock-absorbing springs 44 at both ends of 42, on each of the height-increasing steels 42, the top ends of the two vertical steels 43 are fixedly connected by a connecting rod 45, the shock-absorbing springs 44 include multiple groups and the upper and lower ends are respectively fixed by a first plane steel 46 and a second plane steel 47, the second plane steel 47 is welded to the bottom plate 41 as a whole, the two ends of the first plane steel 46 are located at the bottom of the connecting rod 45, and a matching steel 48 is also vertically fixed to the center of the first plane steel 46, and the top of the matching steel 48 is in contact with the bottom surface of the outer bottom frame 3 for support.

[0021] In order to ensure the stability of the connection between the shock absorbing assembly 4 and the bottom of the cabinet 1, in this embodiment, the center of the bottom of the outer bottom frame 3 is concave upward and a reinforcing steel is fixed at the concave part. The reinforcing steel is planar and fits tightly with the top surface of the matching steel 48.

[0022] Similarly, the shock absorbing components 4 are two and are covered with a protective plate 6 with a hollow bottom. The protective plate 6 is a rectangular structure and is not exposed on the bottom surface of the cabinet 1. The top ends are welded and fixed to the outer bottom frame 3.

[0023] Through the above structural layout, after the actual switch cabinet is installed and positioned, the weight of the cabinet body and the internal electrical components can be supported by the outer bottom frame 3 at the bottom. Similarly, the shock-absorbing assembly 4 arranged at the bottom of the outer bottom frame 3 can buffer the weight of the entire cabinet body. Specifically, the shock-absorbing assembly 4 is first hollowed and raised by a parallel heightening steel 42, and then the top surface of the matching steel 48 is fitted with the ground of the outer bottom frame 3. During the downward pressure of the cabinet body, the shock-absorbing spring 44 placed between the bottom plate 41 and the matching steel 48 will be compressed to a certain extent. In order to ensure the consistency of the compression change of the shock-absorbing spring 44, this example also connects the upper and lower ends of the shock-absorbing spring 44 by a first flat steel 46 and a second flat steel 47 to ensure the uniformity of its force. At the same time, the reset of the spring is limited by placing a connecting rod, that is, after the cabinet body 1 is installed, the two ends of the first flat steel 46 should be located at the bottom of the two connecting rods 45, and the shock-absorbing spring 44 is in a compressed state, thereby reducing unnecessary shaking caused by the operation of external equipment.

[0024] Furthermore, a busbar bracket 7 is fixed to the side end of the frame 2, and an electrical installation plate 8 corresponding to the opening of the cabinet 1 is fixed to the center of the frame 2. The matching steel 48 is an I-shaped steel structure and an integrated reinforcement plate 9 is welded at the corresponding I-shaped groove. The cabinet 1 is a single-door and a built-in handle 10 is provided at the door opening. Hanging rings 11 are also fixed to the four corners of the top of the cabinet 1.

[0025] The busbar bracket 7 and the electrical installation plate 8 are for the convenience of the subsequent deployment of electrical components, and the reinforcement plate 9 can cooperate with the solid reinforcement block 5 to further enhance the stability of the connection between the shock absorbing assembly 4 and the cabinet 1. The lifting ring 11 is for the convenience of lifting and transportation of the cabinet 1. The handle 10 is built-in, which is beautiful and practical.

[0026] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
