Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a dual-circuit power supply switching device. Background Art

[0002] The dual power switch is a special electrical device that is mainly used to automatically switch to the backup power supply when the main power fails or the power goes out, so as to ensure the continuity and stability of the power supply. The working principle of the dual power switch is based on microprocessor control. When the main power fails or the power goes out, the switch can quickly detect this change and automatically switch to the backup power supply, so that the equipment can continue to operate normally.

[0003] This type of switch is widely used in important places such as high-rise buildings, computer rooms, hospitals, airports, and docks where power outages are not allowed. In addition, the traditional two-way power switch is also equipped with a manual adjustment handle so that the operator can manually select the power path when the automatic switching mechanism fails or human intervention is required, thereby ensuring the reliability and flexibility of the power supply. However, the manual adjustment handle of the traditional two-way power switch is not equipped with an anti-mistouch structure. Therefore, inadvertent touch or misoperation by the operator may cause unnecessary switching of the power supply, affecting the normal operation of the equipment and even causing data loss. Secondly, in an emergency, if the operator mistakenly operates the manual adjustment handle due to nervousness or misjudgment, it may aggravate the problem of power supply and even cause more serious consequences.

[0021] like Figure 3-Figure 4As shown, a second fixing seat 10 is fixedly installed at the front end of the adjusting shaft 5, and a through-type through hole is opened in the center position of the adjusting shaft 5 and the second fixing seat 10. A connecting shaft 11 is fixedly installed at the front end of the adjusting shaft 5. The longitudinal section of the connecting shaft 11 is rectangular. One end of the adjusting shaft 5 is inserted and installed in the through holes of the first fixing seat 4 and the second fixing seat 10, and the connecting shaft 11 is placed at the front end of the second fixing seat 10. First limiting grooves 12 are opened on both sides of the connecting shaft 11. A rectangular cabinet 1 is set at the front end of the adjusting shaft 5, which can facilitate the driving handle 8 to drive the adjusting shaft 5 to rotate and adjust;

[0022] like Figure 3-4 As shown, a limit pin 13 is fixedly installed at the front end of the front end plate 7, and a plurality of connecting seats 14 are fixedly installed at the rear end of the front end plate 7. A second slot 24 is opened at the center position in the front end plate 7. Two fixing blocks 15 are also fixedly installed on the outer side of the front end plate 7. A second limit slot 16 is opened in the fixing block 15. The front end plate 7 is fixedly installed at the front end of the second fixing seat 10 through the connecting seat 14 and screws, and the second slot 24 is inserted and installed on the outer side of the connecting shaft 11. Two fixing blocks 15 are arranged on the outer side of the front end plate 7, which can cooperate with the pressing handle 9 to realize the rotation limit of the driving handle 8. The pressing handle 9 is an inverted L-shaped structure. A limit block 17 is fixedly installed at one end of the pressing handle 9. The pressing handle 9 is rotatably installed in the driving handle 8, and a first compression spring 18 is also movably connected between the pressing handle 9 and the driving handle 8. A guide spring 18 is fixedly installed on the upper end of the driving handle 8. Plate 19, a guide groove 20 is provided in the guide plate 19, and a first slot 21 is also provided on the driving handle 8 located below the guide plate 19. A limit screw 22 is threadedly connected to one side of the first slot 21. The driving handle 8 is inserted and installed at one end of the connecting shaft 11 through the first slot 21, and one end of the limit screw 22 is inserted and installed in the first limit slot 12. The guide slot 20 is inserted and installed on the limit pin 13, and the limit block 17 is clamped in the second limit slot 16 of the corresponding fixed block 15. The connecting shaft 11 between the driving handle 8 and the front end plate 7 is provided with a second compression spring 23. The driving handle 8 is pressed through the cooperation of the handle 9, the limit block 17, the fixed block 15, the second limit slot 16, and the second compression spring 23. The driving handle 8 needs to be released twice before the connecting shaft 11 can be rotated.

[0023] It should be noted that the utility model is a dual-way power switching device. When the adjusting shaft 5 is rotated and adjusted, the driving handle 8 can be held with one hand, and the pressing handle 9 can be pressed in the direction of the driving handle 8. The pressing handle 9 rotates at the rear end of the driving handle 8 and compresses the first compression spring 18. At the same time, the limiting block 17 at one end of the pressing handle 9 moves a certain distance in the second limiting groove 16 of the corresponding fixing block 15, and the second limiting groove 16 continues to limit the limiting block 17. At this time, the driving handle 8 can be pushed in the direction of the front end plate 7 while pinching the pressing handle 9, so that the driving handle 8 is moved toward the front end plate 7 on the connecting shaft 11 through the first slot 21 and the limiting screw 22. The driving handle 8 also compresses the second compression spring 23 on the outer side of the connecting shaft 11 toward the side of the front end plate 7, so that the driving handle 8 continues to drive the limiting block 17 at one end of the pressing handle 9 to move in the second limiting groove 16, and the limiting block 17 moves out of the current second limiting groove 16, so that the driving handle 8 drives the connecting shaft 11 to rotate ninety degrees through the first slot 21, and the connecting shaft 11 drives the adjusting shaft 5 to rotate ninety degrees, so that the power supply can be switched, and then, the pressing handle 9 and the driving handle 8 can be released, and the driving handle 8 can be reset and moved by the force of the second compression spring 23, and the limiting block 17 is stuck in the corresponding second limiting groove 16;

[0024] When performing the above steps, there is no particular order in which to press the pressing handle 9 or push the driving handle 8 first, that is, pressing the pressing handle 9 or pushing the driving handle 8 alone cannot make the limit block 17 completely disengage from the second limit groove 16, so both operations need to be completed before the limit block 17 can be moved out of the second limit groove 16 to realize the rotation of the driving handle 8, thereby playing a double role in preventing accidental touch.
