A left end surface of the lock block 102 is provided with the second mounting space 104. The spring baffle 500 is provided with a through hole 501. A right end of the stabilizing shaft 101 is connected to the lock block 102 by the second mounting space 104, and a left end of the stabilizing shaft 101 runs through the through hole 501 on the spring baffle 500 and extends to outside of the spring baffle 500.
The triggering spring 103 is sleeved on the stabilizing shaft 101 and stuck between the spring baffle 500 and the lock block 102. The triggering spring 103 can exert force on the lock block 102 and can drive the lock block 102 to move toward a direction away from the spring baffle 500.
It should be noted here that the above embodiments are only exemplary embodiments of the present application, and do not constitute any limitation to the present application. The connection manner between the spring baffle 500 and the fixing block 200 includes but is not limited to screw connection. Meanwhile, the connection manner between the stabilizing shaft 101 and the lock block 102 includes but is not limited to threaded connection.
In an embodiment of the present application, the triggering assembly 300 includes a triggering shaft 301 and a triggering head 302. The fixing block 200 is provided with a sliding slot 202 and a locking slot 203. The climb-free system trolley 400 is provided with a chute 401 for allowing the triggering shaft 301 to move. The lock block 102 is further provided with a first mounting space 105.
An end of the triggering shaft 301 runs through the chute 401 and the sliding slot 202, and is connected to the first mounting space 105. Another end of the triggering shaft 301 is connected to the triggering head 302. The triggering shaft 301 is provided with a sliding block 303 and a locking block 304.
The sliding block 303 can slide from the sliding slot 202 to the locking slot 203, to drive the locking block 304 to slide and be stuck in the locking slot 203, and drive the locking assembly 100 to be in the unlocked state.
Further, in an embodiment of the present application, the triggering shaft 301 can be pulled to a position where the locking block 304 can be disengaged from the locking slot 203, and the triggering spring 103 drives the sliding block 303 to slide from the locking slot 203 into the sliding slot 202, and drive the locking assembly 100 to be in the locked state, where the lock block 102 is clamped in a sliding rail 800 of the climb-free system, and the climb-free system trolley 400 is locked to a target position.
Further, in an embodiment of the present application, the triggering assembly 300 further includes an anti-drop spring 305 and a washer 306. The anti-drop spring 305 is sleeved on the triggering shaft 301. Also, the anti-drop spring 305 is stuck between the climb-free system trolley 400 and the fixing block 200. The washer 306 is mounted between the climb-free system trolley 400 and the anti-drop spring 305.
For example, as shown in
As shown in
A locking block 304 and a sliding block 303 are formed on the triggering shaft 301 in sequence from top to bottom at a position near the middle of the triggering shaft 301. The anti-drop spring 305 is sleeved on the triggering shaft 301, and the anti-drop spring 305 is located between the fixing block 200 and the triggering head 302. The washer 306 is mounted between the anti-drop spring 305 and the climb-free system trolley 400, to prevent the anti-drop spring 305 from loosening and dropping.
In a specific use process, in an initial state, the locking block 304 on the triggering shaft 301 is stuck in the locking slot 203 on the fixing block 200. When the climb-free system trolley 400 is out of control, the triggering head 302 is pulled upwards, and the triggering head 302 drive the triggering shaft 301 to move upwards, and the locking block 304 is disengaged from the locking slot 203 and the sliding block 303 is located in the sliding slot 202. At this time, the triggering spring 103 exerts force on the lock block 102, to drive the lock block 102 to move toward the direction away from the spring baffle 500, the sliding block 303 slides along the sliding slot 202 to the direction away from the spring baffle 500, the lock block 102 protrudes out of the hollow cavity 201 of the fixing block 200 and is clamped in the sliding rail 800 of the climb-free system, and the climb-free system trolley 400 stops operating and is locked in a certain position to ensure safety. Alternatively, when the climb-free system trolley 400 stops at a target working position, the locking assembly can be in the locked state, to improve the stability and safety of the climb-free system trolley 400.
When the climb-free system trolley 400 is in a normal operation state and needs to slide up and down freely, the triggering head 302 can be held and controlled to move toward a direction proximal to the spring baffle 500, and the sliding block 303 moves in the sliding slot 202 along a direction proximal to the locking slot 203. When the sliding block 303 slides to the position where the locking slot 203 is located, the triggering head 302 can be pressed downward, and the locking block 304 is stuck in the locking slot 203. At this time, the lock block 102 is retracted back into the hollow cavity 201 of the fixing block 200 and disengaged from the sliding rail 800 of the climb-free system.
In one embodiment of the present application, as shown in
It should be noted here that the above-mentioned embodiments are only exemplary embodiments of the present application, and do not constitute any limitation to the present application. For example, the connection manner between the triggering head 302 and the triggering shaft 301 includes but is not limited to screw connection.
In one embodiment of the present application, as shown in

Further, in an embodiment of the present application, the locking slot 203 in the fixing block 200 and the locking block 304 of the triggering assembly 300 are engaged with each other. The triggering assembly 300 is inserted into the fixing block 200 and into the locking assembly 100 in the fixing block 200. When the triggering assembly 300 is pulled toward the spring baffle 500, the locking block 304 of the triggering assembly 300 slides into the locking slot 203 of the fixing block 200 through the sliding slot 202 of the fixing block 200, and the triggering assembly 300 is locked in the locking slot 203 and cannot move back and forth. Since the triggering assembly 300 is inserted into the locking assembly 100, the locking assembly 100 is also restricted from moving.
Further, in an embodiment of the present application, the locking assembly 100 is provided with a triggering spring 103. When the triggering head 302 is lifted, the locking block 304 of the triggering assembly 300 is disengaged from the locking slot 203 of the fixing block 200. The triggering spring 103 in a compressed state in the locking assembly 100 will be released quickly, and the lock block 102 will be ejected and clamped in the sliding rail 800, to stop the operation of the climb-free system trolley 400.
