[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1 to 12 As shown, an automatic transfer switch with a safety device includes a U-shaped plate 1. A switch body 2 is fixedly connected to the inner wall of the U-shaped plate 1. An upper horizontal plate 3 is attached to the upper surface of the U-shaped plate 1, and a lower horizontal plate 4 is attached to the bottom of the U-shaped plate 1. First rectangular holes 5 are provided on both the upper and lower sides of the U-shaped plate 1. Hollow blocks 6 are fixedly connected to the bottom of both the upper horizontal plate 3 and the bottom of both the lower horizontal plate 4. The surface of the hollow blocks 6 is slidably connected to the inner wall of the first rectangular holes 5. Cover plates 7 are fixedly connected to the front of both the upper horizontal plate 3 and the lower horizontal plate 4. A first cylinder 8 is fixedly connected to the inner wall of the hollow blocks 6. A cylinder 9 is fitted onto the surface of a cylinder 8. A slider 10 is fixedly connected to the surface of the cylinder 9. A fixing post 11 is fixedly connected to the back of the slider 10. A fixing cylinder 12 is fitted onto the surface of the fixing post 11. The bottom of the fixing cylinder 12 is fixedly connected to the inner wall of the U-shaped plate 1. A second rectangular hole 13 is opened inside the cover plate 7. The inner wall of the second rectangular hole 13 is slidably connected to the surface of the slider 10. A first U-shaped post 14 is fixedly connected to the front of the slider 10. A second U-shaped post 15 is fixedly connected to the front of the cover plate 7. Locks 16 are fitted onto the inner walls of both the first U-shaped post 14 and the second U-shaped post 15.

[0019] The U-shaped plate 1 has wire holes 17 on both the upper and lower sides, and grooves 18 are provided inside the upper horizontal plate 3 and the lower horizontal plate 4. The grooves 18 are located to the right of the wire holes 17. The front of the switch body 2 is provided with terminals 19, which are aligned with the wire holes 17.

[0020] The maximum distance between the bottom end of the fixed column 11 and the inner wall of the U-shaped plate 1 is greater than the height of the fixed cylinder 12. The front of the slider 10 is fixedly connected to the strip column 20, which is located above the first U-shaped column 14.

[0021] It should be noted that, through the cooperation of the U-shaped plate 1, the upper horizontal plate 3, the lower horizontal plate 4, the first rectangular hole 5, and the hollow block 6, the cover plate 7 can only move left and right on the U-shaped plate 1. Through the cooperation of the first cylinder 8, the cylinder 9, the slider 10, and the second rectangular hole 13, the fixing post 11 can only move up and down. The strip post 20 makes it more convenient for the user to move the fixing post 11. When the fixing post 11 is inserted into the fixing cylinder 12, the cooperation between the fixing post 11 and the fixing cylinder 12 prevents the cover plate 7 from moving left and right. When the fixing post 11 is separated from the fixing cylinder 12, the cover plate 7 can move freely left and right on the U-shaped plate 1.

[0022] When the first U-shaped post 14 and the second U-shaped post 15 are aligned, the first U-shaped post 14 and the second U-shaped post 15 can be locked together by the lock 16. Through the cooperation of the first U-shaped post 14, the second U-shaped post 15 and the lock 16, the fixing post 11 cannot be moved out of the fixing cylinder 12. At this time, through the cooperation of the fixing post 11 and the fixing cylinder 12, the cover plate 7 can be locked in the operating position of the switch body 2. The cover plate 7 prevents unauthorized personnel from operating the automatic transfer switch, thereby reducing the risk of power supply accidents. The lock 16 is a horizontal padlock.

[0023] After passing through the wire hole 17, the wire is connected to the terminal block 19. At the same time, the groove 18 ensures that the wire will not affect the movement of the cover plate 7 when it moves.

[0024] like Figures 1 to 13 As shown, a first ring 21 is fixedly connected to the back of the U-shaped plate 1, a bearing 22 is fixedly connected to the inner wall of the first ring 21, a second cylinder 23 is fixedly connected to the inner ring of the bearing 22, a mounting bracket 24 is fixedly connected to the surface of the second cylinder 23, a second ring 25 is fixedly connected to the bottom of the U-shaped plate 1, a threaded hole 26 is provided inside the second ring 25, a stepped hole 27 is provided inside the mounting bracket 24, a positioning bolt 28 is fitted to the inner wall of the stepped hole 27, the surface of the positioning bolt 28 is threadedly connected to the inner wall of the threaded hole 26, and a mounting hole 29 is provided inside the mounting bracket 24.

[0025] The second ring 25 is located outside the first ring 21, and the axis of the second ring 25 coincides with the axis of the first ring 21.

[0026] It should be noted that the first ring 21 and the second cylinder 23 are connected together by the bearing 22. Through the cooperation of the first ring 21, the bearing 22, and the second cylinder 23, the mounting bracket 24 can rotate around the second cylinder 23. The second ring 25 has multiple threaded holes 26, which are circumferentially distributed around the axis of the second cylinder 23. When the positioning bolt 28 is inserted into the stepped hole 27 and screwed into the threaded hole 26, the mounting bracket 24 can rotate around the second cylinder 23. With proper coordination, the mounting bracket 24 cannot rotate. When the positioning bolt 28 is unscrewed from the threaded hole 26, the mounting bracket 24 can rotate around the second cylinder 23. At the same time, by screwing the positioning bolt 28 into the threaded hole 26 at different positions, the position of the mounting hole 29 can be changed. Thus, the position of the mounting hole 29 can be located on the upper and lower sides of the U-shaped plate 1, or on the left and right sides of the U-shaped plate 1, thereby adapting to different installation spaces, distances between adjacent devices, and other scenarios, expanding the applicability of the automatic transfer switch.

[0027] The working principle of this utility model is as follows: When installing the automatic transfer switch, first adjust the fit of the mounting hole 29 according to the installation requirements. During adjustment, first unscrew the positioning bolt 28 from the threaded hole 26. Then, by rotating the mounting bracket 24, the position of the mounting hole 29 can be changed. When the mounting hole 29 is rotated to the appropriate position, insert the positioning bolt 28 into the stepped hole 27 and screw it into the corresponding threaded hole 26. At this time, the fit of the positioning bolt 28, the stepped hole 27 and the threaded hole 26 can fix the mounting hole 29 in the designated position. Then, insert the fixing bolt into the mounting hole 29 and fix the automatic transfer switch in the designated position with the fixing bolt.

[0028] When the automatic selector switch needs to be operated, first unlock the lock 16 with the key, and separate the lock 16 from the first U-shaped post 14 and the second U-shaped post 15. Then, by moving the strip post 20, separate the fixed post 11 from the fixed cylinder 12. By moving the strip post 20 to the left, the operating position of the cover plate 7 and the switch body 2 is offset. At this time, the user can operate the switch body 2. After the user has finished operating, move the strip post 20 to position the cover plate 7 at the operating position of the switch body 2, and move the fixed post 11... Inserted into the fixed cylinder 12, the first U-shaped post 14 and the second U-shaped post 15 are aligned. Then, the first U-shaped post 14 and the second U-shaped post 15 can be locked together by the lock 16. Through the cooperation of the first U-shaped post 14, the second U-shaped post 15 and the lock 16, the fixed post 11 cannot be moved out of the fixed cylinder 12. At this time, through the cooperation of the fixed post 11 and the fixed cylinder 12, the cover plate 7 can be locked in the operating position of the switch body 2, and the cover plate 7 prevents unauthorized personnel from operating the automatic changeover switch.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
