DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 In an embodiment of the utility model, a transformer installation cabinet includes an installation cabinet 1, a fixing mechanism 2 is provided at the front end of the installation cabinet 1, and a limiting mechanism 3 is provided in the fixing mechanism 2;

[0023] The fixing mechanism 2 includes a movable frame 201, which is rotatably connected to the front end of the installation cabinet 1 through a pin shaft.

Limiting blocks 206 are fixedly connected on the left and right sides of the bottom of the installation cabinet 1. A movable block 204 is provided on the top of the installation cabinet 1.

[0024] It should be noted that by placing the transformer body 205 in the movable frame 1, using the pull block 209 to limit the movable frame 201, placing the movable frame 201 and flipping it over again, the top of the transformer body 205 is limited by setting the movable block 204.

[0025] In an optional embodiment: the bottoms of the two pull blocks 209 are fixedly connected to the second springs 208 , and the other ends of the second springs 208 are fixedly connected to the bottom of the installation cabinet 1 .

[0026] It should be noted that when the movable frame 201 moves, the top inclined surfaces of the pull blocks 209 arranged on both sides of the installation cabinet 1 are gradually squeezed by the movable frame 201 that is moving, and exert downward pressure on the second spring 208. When the pull block 209 completely penetrates the movable frame 201, the reaction force of the second spring 208 pushes the pull block 209 to move upward, and the pull block 209 is used to limit the movable frame 201 to prevent the movable frame 201 from moving.

[0027] In an optional embodiment: the inner wall of the installation cabinet 1 is slidably connected with a movable plate 210, the rear end of the movable plate 210 is fixedly connected with uniformly distributed first springs 207, and the other ends of the first springs 207 are fixedly connected to the rear end of the installation cabinet 1.

[0028] It should be noted that the reaction force of the first spring 207 pushes the movable plate 210 to move forward for compression, thereby preventing the transformer body 205 from shaking forward and backward.

[0029] In an optional embodiment: a protective cover 202 is fixedly connected to the top of the installation cabinet 1, the inner diameter of the protective cover 202 is threadedly connected to a threaded column 203, and the threaded column 203 is rotatably connected to the top of the movable block 204 through a bearing.

[0030] It should be noted that, by rotating the two threaded columns 203 at the top, the movable block 204 is controlled to gradually move downward from the protective cover 202 and engage with the top of the transformer body 205 to increase the position limit of the transformer body 205 .

[0031] In an optional embodiment, the limiting mechanism 3 includes a glass window 301 . There are two glass windows 301 , and both of the two glass windows 301 are arranged in the movable frame 201 .

[0032] It should be noted that the staff can observe the transformer body 205 through the glass window 301 and understand the use of the transformer body 205 at any time.

[0033] In an optional embodiment: the left and right sides of the inner wall of the movable frame 201 are rotatably connected with connecting blocks 302 through pins, and the opposite sides of the connecting blocks 302 are fixedly connected to the corresponding glass windows 301, and the left and right sides of the inner bottom of the movable frame 201 are provided with riveted spring buckles 303.

[0034] It should be noted that by pressing the riveted spring buckles 303 arranged on the left and right sides of the bottom of the movable frame 201, the two glass windows 301 are controlled to drive the connecting block 302 to rotate on the inner wall of the movable frame 302, so that the staff can inspect the transformer body 205. When the inspection is completed, the glass windows 301 are closed and limited by the riveted spring buckles 303.

[0035] In an optional embodiment: the left and right sides of the inner wall of the movable frame 201 are fixedly connected with coil springs 305 , the other ends of the two coil springs 305 are fixedly connected with the same cleaning block 304 , and the rear end of the cleaning block 304 is in close contact with the glass window 301 .

[0036] It should be noted that the cleaning block 304 is pulled to clean the surface of the glass window 301 to keep the surface of the glass window 301 clean, and the reaction force of the coil spring 305 is used to control the cleaning block 304 to return to its original position.

[0037] The working principle of the utility model is:

[0038] When installing the transformer installation cabinet, first fix the installation cabinet 1, and slide the transformer body 205 on the inner wall of the movable frame 201 which is perpendicular to the installation cabinet 1. When the transformer body 1 slides to the rear end of the movable frame 201, the movable frame 201 is flipped around the connection between the installation cabinet 1 and the movable frame 201, so that the movable frame 201 and the installation frame 1 are parallel to each other. At the same time, when the movable frame 201 moves, the top inclined surfaces of the pull blocks 209 arranged on both sides of the installation cabinet 1 are gradually squeezed by the movable frame 201, and a downward pressure is exerted on the second spring 208. When the pull blocks 209 completely penetrate the movable frame 201, the second spring 208 is pressed downward. The reaction force of the spring 208 pushes the pull block 209 to move upward, and the pull block 209 is used to limit the movable frame 201 to prevent the movable frame 201 from moving. After the transformer body 205 is turned over and enters the installation cabinet 1, the limit block 206 fixed at the bottom of the transformer body 205 is limited, and the reaction force of the first spring 207 pushes the movable plate 210 to move forward for squeezing to prevent the transformer body 205 from shaking back and forth. By rotating the two threaded columns 203 on the top, the movable block 204 is controlled to gradually move downward from the protective cover 202 and engage with the top of the transformer body 205 to increase the limit on the transformer body 205.

[0039] When it is necessary to inspect the transformer body 205, the riveted spring buckles 303 set on the left and right sides of the bottom of the movable frame 201 are pressed, and the two glass windows 301 are controlled to drive the connecting block 302 to rotate on the inner wall of the movable frame 201, so that the staff can inspect the transformer body 205. When the inspection is completed, the glass window 301 is closed and limited by the riveted spring buckle 303, and the cleaning block 304 is pulled to clean the surface of the glass window 301 with the cleaning block 304 to keep the surface of the glass window 301 clean, so that the staff can observe the transformer body 205 through the glass window 301. The reaction force of the coil spring 305 is used to control the cleaning block 304 to return to its original position.
