The gear 1341 is connected to the handle 133, it is understood that the gear 1341 is connected to the handle 133, and the gear 1341 may be directly fixedly connected to the handle 133, where the gear 1341 rotates coaxially with the handle 133 at the same direction and same rotation speed; the gear 1341 may be connected to the handle 133 by other transmission means, and the handle 133 may still rotate to drive the gear 1341. The gear 1341 is rotatably coupled to the rotation shaft 1345 to coaxially rotate with the rotation shaft 1345. The rack 1342 is connected to the lock block 132, and the gear 1341 is meshed with the rack 1342, so that when the gear 1341 rotates, the rack 1342 can be driven to move up and down, thereby driving the lock block 132 to move relative to the lock body 131.

When the handle 133 rotates between the first moving position and the second moving position, the gear 1341 is driven to rotate around the rotation shaft 1345, and as the gear 1341 is meshed with the rack 1342, the gear 1341 rotates to drive the rack 1342 to move up and down, so as to drive the locking block 132 to move relative to the lock body 131 to protrude or retract the lock body 131.

When the gear 1341 and the rack 1342 are in the engaged state as shown in fig. 8, the lock block 132 protrudes the lock body 131 and the quick release lock 130 is in the locked state when the gear 1341 rotates clockwise. When the gear 1341 rotates counterclockwise, the locking block 132 retracts the lock body 131, and the quick release lock 130 is in the unlocked state.

Referring to fig. 8, the linkage 134 optionally further includes a pawl 1343, a dial 1344, and a trigger assembly 135, according to some embodiments of the present application. The turntable 1344 is fixedly connected to the handle 133 and rotatably connected to the rotation shaft 1345, and when the handle 133 rotates between the first moving position and the second moving position, the turntable 1344 rotates coaxially with the handle 133 (about the rotation shaft 1345) in the same direction and at the same rotation speed.

As shown in fig. 8, the gear 1341 is an inner ratchet gear, the outer ring of the gear 1341 is teeth adapted to the rack 1342, and the inner ring of the gear 1341 is an inner ratchet with ratchet teeth. The pawl 1343 is rotatably coupled to the turntable 1344 to engage with the inner ratchet of the gear 1341, and as shown in fig. 8, a pin is provided on a surface of the turntable 1344, and the pawl 1343 is rotatably coupled to the pin such that the pawl 1343 can be rotatably coupled to the turntable 1344 such that the pawl 1343 can move relative to the inner ratchet of the gear 1341 to engage with or disengage from the inner ratchet of the gear 1341.

As shown in fig. 8, the trigger assembly 135 is located at the handle 133, the trigger assembly 135 is connected to the pawl 1343, and the trigger assembly 135 moves relative to the handle 133 to drive the pawl 1343 to rotate relative to the turntable 1344, and when the pawl 1343 rotates relative to the turntable 1344, the pawl 1343 moves relative to the inner ratchet of the gear 1341 to engage or disengage with the inner ratchet of the gear 1341.

As shown in fig. 8, trigger assembly 135 includes a trigger tab 1351 and a link 1352. The link 1352 is located inside the handle 133 and slidably engaged with the handle 133, the handle 133 is hollow, and the link 1352 is located inside the handle 133 and movable inside the handle 133 with respect to the handle 133. The trigger piece 1351 is movably connected to an end of the handle 133 remote from the turntable 1344, the trigger piece 1351 being located outside the handle 133, the trigger piece 1351 being provided with a hole to allow the trigger piece 1351 to be connected to the link 1352 inside the handle 133. The link 1352 has its ends connected to the trigger 1351 and the pawl 1343, respectively, and the trigger 1351 moves relative to the handle 133 to drive the pawl 1343 to engage or disengage the inner ratchet of the gear 1341.

Referring to fig. 8, when trigger piece 1351 moves relative to handle 133 in a direction away from pawl 1343, pawl 1343 rotates relative to rotary plate 1344 to engage with the inner ratchet of gear 1341, and when trigger piece 1351 moves relative to handle 133 in a direction toward pawl 1343, pawl 1343 rotates relative to rotary plate 1344 to disengage from the inner ratchet of gear 1341.

When the pawl 1343 is engaged with the gear 1341, the rotation of the handle 133 can drive the turntable 1344 and the pawl 1343 to rotate about the rotation axis 1345, the gear 1341 is locked with the pawl 1343 in one direction, as in the embodiment shown in fig. 8, when the handle 133 drives the turntable 1344 and the pawl 1343 to rotate counterclockwise about the rotation axis 1345, the gear 1341 rotates synchronously with the turntable 1344, and when the handle 133 drives the turntable 1344 and the pawl 1343 to rotate clockwise about the rotation axis 1345, the gear 1341 is not affected by the rotation of the turntable 1344. When the handle 133 is in the state shown in fig. 8, the handle 133 is in the first moving position, and at this time, the locking block 132 is retracted into the lock body 131, and the quick release lock 130 is in the unlocked state. When the handle 133 rotates counterclockwise, driving the turn table 1344 and the pawl 1343 to rotate counterclockwise about the rotation axis 1345, the gear 1341 rotates in synchronization with the turn table 1344, and the lock block 132 retracts the lock body 131, so that the quick release lock 130 is switched from the locked state to the unlocked state.

When the pawl 1343 and the gear 1341 are not in contact, rotation of the handle 133 can rotate the turntable 1344 and the pawl 1343 about the rotation axis 1345, but the gear 1341 is not affected by rotation of the turntable 1344. As shown in fig. 8, the lock block 132 is connected with a first spring member 136, and the first spring member 136 has a tendency to drive the lock block 132 to protrude from the lock body 131. When the pawl 1343 and the gear 1341 are not in contact, the lock block 132 protrudes out of the lock body 131 under the action of the first spring member 136.

Referring to fig. 8, according to some embodiments of the present application, optionally, the handle 133 is connected to the lock body 131 through a return spring 138, where the return spring 138 has a tendency to rotate the handle 133 to the first moving position. When no external force is applied, the handle 133 remains in the first moving position. When an external force is applied (e.g., a person pulls the handle 133), the handle 133 rotates counterclockwise and can rotate to the second movement position. When the external force is removed, the handle 133 is reset to the first moving position.

When the quick release lock 130 is assembled in the chute 121, the trigger piece 1351 moves toward the direction approaching the pawl 1343 relative to the handle 133, the pawl 1343 rotates relative to the rotary plate 1344 to be out of contact with the inner ratchet wheel of the gear 1341, and the locking block 132 protrudes out of the lock body 131 under the action of the first elastic member, so that the quick release lock 130 is in a locking state.

When the quick release lock 130 needs to be unlocked, the trigger piece 1351 moves relative to the handle 133 towards a direction away from the pawl 1343, so as to drive the pawl 1343 to rotate relative to the rotary table 1344, so that the pawl 1343 is meshed with the inner ratchet wheel of the gear 1341, at this time, the handle 133 rotates anticlockwise (under the action of external force), and drives the rotary table 1344 and the pawl 1343 to rotate anticlockwise around the rotary shaft 1345, the gear 1341 rotates synchronously with the rotary table 1344, and the locking block 132 retracts the lock body 131, so that the quick release lock 130 is switched from the locking state to the unlocking state, and the quick release lock 130 is moved out of the sliding slot 121 from the opening 122 of the sliding slot 121, thereby completing the separation of the connecting seat 110 from the sliding rail 120.

In the above-mentioned scheme, the quick release lock 130 is provided to connect the connection base 110 and the slide rail 120, and the connection base 110 and the slide rail 120 are respectively connected to the object 200 and the vehicle body 300, so as to realize the detachable connection of the object 200 and the vehicle body 300. And the quick release lock 130 can be slidably coupled with respect to the coupling base 110 to facilitate moving the position of the object 200 without disassembly. The quick release lock 130 is arranged to be connected with the locking block 132 through the linkage part 134 by arranging the handle 133, so that the handle 133 can rotate between the first moving position and the second moving position to drive the locking block 132 to move relative to the lock body 131, and then the quick release lock 130 is switched between a locking state and an unlocking state, thereby realizing that the connecting seat 110 is connected or detached from the sliding rail 120, and realizing that the object 200 is detachably connected with the vehicle body 300.
