The moving direction of the movable plate 335 is substantially perpendicular to the extending direction of the lock tongue channel 3310 (as shown in L2 direction in fig. 12), the movable plate 335 further has a latch portion 3350 bent and extended toward the fixing plate 334, and correspondingly, the fixing plate 334 has a relief opening 3340 for the latch portion 3350 to pass through. The lock tongue 332 also has a lock hole 3320 through which the locking portion 3350 of the movable piece 335 passes. The unlock button 3311 is movable between a first position and a second position in a direction substantially parallel to the deadbolt passage 3310 (e.g., direction L1 shown in fig. 12). The elastic member 333 of the present embodiment is a spring that abuts against the inner end of the unlock button 3311 so that the unlock button 3311 always has a tendency to move from the second position to the first position.

The unlocking button 3311 is provided with a track groove 3312 for limiting the side of the movable plate 335. When the unlocking button 3311 is pressed, the movable plate 335 is driven to move away from the fixed plate 334 to the unlocking position by the limiting action of the track groove 3312 when the unlocking button 3311 moves from the first position to the second position, that is, the locking portion 3350 on the movable plate 335 is disengaged from the locking hole 3320 of the locking bolt 332, and the locking of the locking bolt 332 is released. After the lock tongue 332 is inserted into the lock box 331, the unlocking button 3311 is reset, that is, the unlocking button 3311 moves from the second position to the first position, the movable plate 335 is driven to move towards the fixed plate 334 to the unlocking position by the limiting action of the track groove 3312, and the locking part 3350 on the movable plate 335 is inserted into the locking hole 3320 of the lock tongue 332 from the yielding opening 3340 passing through the fixed plate 334, so that the lock of the lock tongue 332 is realized.

A micro switch 336 and an alarm module (not shown) are also provided in the lock box 331. The alarm module is preferably an audible alarm that is electrically connected to the microswitch 336. The micro switch 336 of the present embodiment is located in a moving path between a first position and a second position of the unlock button 3311, wherein when the user presses the unlock button 3311 to unlock, the unlock button 3311 moves to the second position, and at this time, the micro switch 336 is triggered, the alarm is turned on corresponding to the control circuit, and an alarm signal is sent to unlock the lock tongue 332.

The pull belt main body 30 of the pull belt assembly of the embodiment is connected with the chair back 21 of the child safety seat through the quick release lock catch, when the pull belt assembly is required to be released, a user only needs to operate the quick release lock catch close to the chair back 21, and the hook at the tail end position of the pull belt does not need to be operated by stretching hands laboriously in the prior art, so that the pull belt assembly well meets the requirements of quick assembly and quick release of the user, and the use experience of the user is improved.
