A damping telescopic rod A205 is fixedly installed between the rear of the limiting block 204 and the rear of the inner wall of the slide 201, and a spring is matched on the outer side of the damping telescopic rod A205. When the staff pulls down to close the designated air switch 1 in the building for power maintenance, it is necessary to lock the closed air switch 1 to prevent other personnel from pulling back the air switch 1. After the operator places the buckle 2 under the air switch 1, he pushes the adjusting rod 202 downward to slide on the inside of the slide groove 201, squeezes the limit block 204 to slide out of the limit groove 203, drives the damping telescopic rod A205 and the outer spring to contract, and makes the locking frame 206 contact the top of the control switch of the air switch 1. After the control switch of the air switch 1 is locked, the damping telescopic rod A205 and the outer spring pop out the limit block 204 to slide into the relative limit groove 203 to limit and fix the locking frame 206, so that the operator can freely adjust the position of the locking frame 206 to lock the control switches of air switches 1 of different sizes, and prevent other personnel from opening the air switch 1 when the operator is performing power maintenance.

[0025] Furthermore, the limit lock mechanism is composed of the limit card slot 207, the limit card frame 3, the groove 301, the damping telescopic rod B4 and the card block 401;

[0026] A limit card slot 207 is embedded and arranged below the lock frame 206, and the limit card slot 207 is arranged in an "L" shape. A limit card frame 3 is arranged above the buckle 2 through a bearing rotation, and the limit card frame 3 is arranged in an "L" shape, and the limit card frame 3 is arranged to slide in the inner side of the limit card slot 207. A groove 301 is embedded and arranged above the limit card frame 3, and the groove 301 is arranged in a semicircular shape. A damping telescopic rod B4 is fixedly installed below the inner wall of the limit card slot 207, and a spring is arranged on the outer side of the damping telescopic rod B4. A card block 401 is fixedly installed below the end of the damping telescopic rod B4, and the card block 401 is arranged in a semicircular shape, and the card block 401 is arranged to slide in the inner side of the groove 301. When the staff When the control switch of the air switch 1 is locked between the lock frame 206 and the buckle 2, it will drive the limit card frame 3 to slide into the inner side of the limit card slot 207. At this time, the staff pushes the limit card frame 3 to rotate through the bearing so that the limit card frame 3 can completely slide into the inner side of the limit card slot 207 for limitation, and squeezes the card block 401 to drive the damping telescopic rod B4 and the outer spring to contract, so that the card block 401 is close to the groove 301, and the damping telescopic rod B4 and the outer spring pop out the card block 401 to slide into the inner side of the groove 301 to limit the limit card frame 3, completing the limit fixing process between the lock frame 206 and the buckle 2, which can prevent the lock frame 206 from loosening after the lock process, and improve the effect of firmly locking and preventing loosening of the control switch of the air switch 1.

[0027] Furthermore, the tensioning and anti-slipping mechanism is composed of a damping telescopic rod C5 and an anti-slipping frame 501;

[0028] A damping telescopic rod C5 is fixedly installed on the side of the buckle 2, and a spring is matched to be arranged on the outside of the damping telescopic rod C5, and an anti-dropout frame 501 is fixedly installed on the side of the end of the damping telescopic rod C5, and the anti-dropout frame 501 is arranged in an "L" shape. When the staff locks the control switch of the air switch 1 with the buckle 2, the anti-dropout frame 501 is pushed to drive the damping telescopic rod C5 and the outer spring to expand, so that the anti-dropout frame 501 is on the side of the control switch of the air switch 1, and then the anti-dropout frame 501 is released to make the damping telescopic rod C5 and the outer spring contract the anti-dropout frame 501, and tighten the buckle 2 to limit it on the side of the control switch of the air switch 1, so as to prevent the buckle 2 from loosening and falling off from the side of the control switch of the air switch 1, thereby improving the effect of the buckle 2 on the stable locking of the air switch 1.

[0029] Embodiment 2:

[0030] like Figure 5 , Figure 6As shown, in addition to the embodiment of the utility model in which a limited card block 204 is slidably arranged inside the slide groove 201 at the rear, and the front of the limited card block 204 is slidably arranged inside the limited groove 203, and the upper corner of the limited card block 204 is arranged in an inclined shape, there is another embodiment in which a limited card block 204 is slidably arranged inside the slide groove 201 at the rear, and the front of the limited card block 204 is slidably arranged inside the limited groove 203, and the upper corner of the limited card block 204 is arranged in an arc shape. When the staff pushes the adjustment rod 202 downward to slide inside the slide groove 201, the limited card block 204 is squeezed When the limit slot 203 is slid out to drive the damping telescopic rod A205 and the outer spring to contract, the arc-shaped corner of the limit block 204 and the inner wall of the limit slot 203 will have a smaller contact area and generate less friction, so that the limit block 204 can slide out of the limit slot 203 more easily, so that the lock frame 206 can contact the top of the control switch of the air switch 1. After the control switch of the air switch 1 is locked, the damping telescopic rod A205 and the outer spring pop out the limit block 204 to slide into the inner side of the relative limit slot 203 to limit and fix the lock frame 206. Compared with the first embodiment, the adjustment is more convenient.

[0031] Working principle: First, the staff pulls down and closes the designated air switch 1 in the building to perform power maintenance. When the closed air switch 1 needs to be locked to prevent other people from pulling back the air switch 1, the staff places the buckle 2 under the air switch 1, pushes the anti-drop frame 501 to drive the damping telescopic rod C5 and the outer spring to expand, and then the anti-drop frame 501 is on the side of the control switch of the air switch 1. Then, the anti-drop frame 501 is released to make the damping telescopic rod C5 and the outer spring contract the anti-drop frame 501, and tighten the buckle 2 to limit it on the side of the control switch of the air switch 1, which can prevent the buckle 2 from loosening and falling off from the side of the control switch of the air switch 1. Then, push the adjusting rod 202 downward to slide on the inside of the slide slot 201, squeeze the limit block 204 to slide out of the limit slot 203, drive the damping telescopic rod A205 and the outer spring to contract, and make the locking frame 206 contact the control switch of the air switch 1. At the top, after the control switch of the air switch 1 is locked, the damping telescopic rod A205 and the outer spring pop-up limit block 204 slide into the inner side of the relative limit groove 203 to limit and fix the lock frame 206. Finally, the staff locks the control switch of the air switch 1 between the lock frame 206 and the buckle 2, and drives the limit card frame 3 to slide into the inner side of the limit card groove 207. At this time, the staff pushes the limit card frame 3 to rotate through the bearing so that the limit card frame 3 completely slides into the inner side of the limit card groove 207 for limitation, and squeezes the card block 401 to drive the damping telescopic rod B4 and the outer spring to contract, so that the card block 401 is close to the groove 301, and the damping telescopic rod B4 and the outer spring pop-up card block 401 slide into the inner side of the groove 301 to limit the limit card frame 3, completing the limit and fixation between the lock frame 206 and the buckle 2, which can prevent the lock frame 206 from loosening after the locking process.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
