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.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a switch cabinet that is easy to maintain, including a cabinet body 1. Two cabinet doors 4 are movably installed on the front side of the cabinet body 1, and handles 5 are installed on the front side of the cabinet doors 4. An air intake grille 6 is fixedly installed in the inner cavity of the cabinet body 1, and the air intake grille 6 is located at the bottom of the cabinet doors 4. An exhaust screen 7 is installed on the top of the cabinet body 1, and viewing windows 8 are installed on both the left and right sides of the cabinet body 1. A fixing component is provided at the bottom of the cabinet body 1. A first movable plate 9 is movably installed near the front side of the inner cavity of the cabinet body 1. A second movable plate 15 is provided behind the first movable plate 9. The second movable plate 15 is movably connected to the inner wall of the cabinet body 1. A counterweight bar 19 is fixedly connected to the rear side of the second movable plate 15. An installation component is provided on the front side of the second movable plate 15 and the first movable plate 9, and a transmission component is provided between the second movable plate 15 and the first movable plate 9.

[0021] The cabinet 1 is fixedly installed on the ground using a fixing component, and the installation is secure. The components are installed inside the cabinet 1 using an installation component, and the power is transmitted between the first movable plate 9 and the second movable plate 15 using a transmission component.

[0022] Please see Figure 1 The fixing component includes two bases 2, which are fixedly connected to the bottom of the cabinet 1 near the left and right sides. Each base 2 has several mounting holes 3, and the inner diameter of the mounting holes 3 is the same.

[0023] The base 2 contacts the ground, and the mounting hole 3 allows screws to be fixed to the ground through the base 2, thus achieving the fixed installation of the cabinet 1 to the ground.

[0024] Please see Figure 2 and Figure 3The installation assembly includes several mounting plates 10, which are fixedly connected to the front sides of the second movable plate 15 and the first movable plate 9, respectively, and each of the mounting plates 10 has a mounting component 11 fixedly installed on its front side.

[0025] The mounting component 11 is used for mounting components, so that the components can be stably installed inside the cabinet 1 without causing any obstruction during subsequent maintenance.

[0026] Please see Figure 3 and Figure 4 The transmission assembly includes two gears 18, which are rotatably connected to the left and right sides of the inner wall of the cabinet 1, and the two gears 18 are meshed with racks 17 on the front and rear sides, respectively. The two racks 17 are fixedly connected to the rear side of the first movable plate 9 and the front side of the second movable plate 15, respectively.

[0027] When the first movable plate 9 moves, it will drive the two racks 17 on it to move synchronously. The two front racks 17 drive the corresponding gears 18 to rotate, and the two gears 18 drive the rear racks 17 to move. The two rear racks 17 together drive the second movable plate 15 to move.

[0028] Please see Figure 3 and Figure 4 The top and bottom of the first movable plate 9 are fixedly connected with several rubber pads 16, and the top and bottom of the second movable plate 15 are fixedly connected with several identical rubber pads 16.

[0029] The use of multiple rubber pads 16 can provide a certain buffering effect when the first movable plate 9 and the second movable plate 15 come into contact with the inner wall of the cabinet 1, thereby improving safety performance.

[0030] Please see Figure 2 , Figure 3 and Figure 4 The first movable plate 9 and the second movable plate 15 are fixedly connected to sliders 12 on both the left and right sides. The inner walls of the cabinet 1 have two slide grooves 13 on both the left and right sides, and the sliders 12 are slidably connected to the inner cavity of the corresponding slide grooves 13.

[0031] The sliding block 12 and the sliding groove 13 work together to limit the movement trajectory of the first movable plate 9 and the second movable plate 15, thereby improving stability.

[0032] Please see Figure 3 A handle 14 is fixedly connected to the front side of the first movable plate 9 near the bottom.

[0033] Specifically, by applying force to the first movable plate 9 by holding the handle 14, the first movable plate 9 is moved down, which in turn moves the components on it down, making subsequent maintenance easier.

[0034] Working principle: When using this application, the cabinet 1 is first installed using the base 2 and the mounting hole 3. Then, the cabinet door 4 is opened using the handle 5, and components are installed on the first movable plate 9 and the second movable plate 15 inside the cabinet 1. The components are then installed on the mounting piece 11. During daily operation, the air intake grille 6 and the exhaust net 7 work together to achieve internal airflow and ensure heat dissipation. The viewing window 8 on the outside of the cabinet 1 allows for viewing of the internal situation.

[0035] When it is necessary to inspect the components inside cabinet 1, the staff can first inspect the multiple components on the front side of the second movable plate 15. Since the second movable plate 15 is located at the bottom, the staff can squat or sit cross-legged on the ground to carry out the inspection. However, when inspecting the components near the top on the first movable plate 9, the staff needs to hold the handle 14 and pull the first movable plate 9 down. The first movable plate 9 moves the multiple components installed on it down. At the same time, the first movable plate 9 drives the corresponding gears to rotate 18 through the two sets of racks 17 on the rear side. The two gears 18 drive the racks 17 on the rear side to move. The two racks 17 on the rear side move the second movable plate 15 up together. The second movable plate 15 moves the counterweight bar 19 on it up. After the top component is inspected, the staff releases the handle 14, and the first movable plate 9 and the second movable plate 15 return to their original positions under the action of the counterweight bar 19.

[0036] 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.
