Specific embodiment
In order to which the technical problems, technical solutions and beneficial effects solved by the present invention is more clearly understood, below in conjunction with
Accompanying drawings and embodiments, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
Referring to shown in FIG. 1 to FIG. 6, one embodiment of the invention discloses a kind of lock construction, including lock body 1, locking bar 2, first
The 3, first torsional spring 4 and positioning component are latched, forms the locked groove 11 with an opening 111 on the lock body 1, the locking bar 2 can be
It is rotated back and forth between lockset position of coupler and lock position to open or close the opening 111.
First lock 3 is rotationally connected on the lock body 1, and the both ends of first torsional spring 4 are connected to described
On first lock 3 and the lock body 1；
When the locking bar 2 turns to lock position by lockset position of coupler, first lock 3 can be in the promotion of the locking bar 2
Under overcome the elastic force of first torsional spring 4 by disengaged position rotate to lock position, it is described first lock 3 be located at lock position
When, first lock 3 stops the locking bar 2 to rotate to lockset position of coupler, and the positioning component limitation described first latches 3 to points
The rotation set off normal so that first lock 3 is maintained at the lock position；
When the positioning component is released and limited the rotation of first lock 3, first lock 3 is by described the
The restoring force of one torsional spring 4 returns back to disengaged position by latching position, is rotated to the locking bar 2 to the lockset position of coupler with releasing
Stop.
The lock construction is rotated back and forth between lockset position of coupler and lock position to turn off or on the lock by locking bar 2
Slot 11, when the locking bar 2 moves to lock position, locking bar 2 drives the rotation of first lock 3, and positioning component is used for
The lock position of first lock 3 limits first lock 3, and then is turned by 3 limitation locking bar 2 of the first lock
It is dynamic, while the first torsional spring 4 twists, to generate elastic deformation, when positioning component releases the limit to first lock 3
When, the elastic recovery of the first torsional spring 4 is able to drive the first lock 3 and returns back to disengaged position, and it releases the rotation to locking bar 2 and limits,
It is fast to unlock reaction speed, does not easily cause the deformation outside torsional spring deformation range, it is safe and reliable for the closure of Yu Suoti 1.
In the present embodiment, the positioning component includes second lock the 5, second torsional spring 6 and push rod device 7, and described second
Lock 5 is connected on the lock body 1, and the both ends of second torsional spring 6 are connected to second lock 5 and the lock body 1
On, elastic deformation occurs in 5 rotation of the second lock and provides torsion restoring force.
Specifically, second lock 5 is abutted each other with first lock 3, first lock 3 drives institute when rotating
The rotation for stating the second lock 5, in the lock position of first lock 3, second lock 5 is by second torsional spring 6
Elastic force is connected to limit first lock, 3 rotations to disengaged position on first lock 3, by first lock 3
It is fixed on the lock position；
When needing to be unlocked the lock body 1, second lock 5 is pushed to be detached from institute by the push rod device 7
The first lock 3 is stated, second lock 5 overcomes the twisting resistance of second torsional spring 6 to twist, to release to first lock
The limitation that button 3 is rotated to disengaged position, 4 elastic recovery of the first torsional spring drives first lock 3 to return back to disengaged position at this time.
By be provided with the first torsional spring 4 first lock 3 and be provided with the second torsional spring 6 second lock 5 between it is mutual
Effect, so that the rotation displacement range of first torsional spring 4 and the second torsional spring 6 mutually limits, is conducive to first torsional spring 4 and exists
The gentle transition rotated between disengaged position and lock position avoids first lock 3 and second lock 5 because rotating width
Spend causes locking bar 2 to be detached from greatly, while second lock 5 can be made to be detached from first lock 3 by the push rod device 7,
The function of quick release is realized by the effect of first torsional spring 4 again.

End 33 is latched, the extrados setting jagged 34 of first lock 3, second lock 5, which has, to abut end 52 and apply
Power end 53.
When the locking bar 2 turns to lock position by lockset position of coupler, the round end of the locking bar 2 and first lock 3
Portion 32 contacts and first lock 3 is pushed to turn to lock position by disengaged position, at this time the lock end of first lock 3
Portion 33 rotation to the locking bar 2 away from it is described rotation end 32 side, the locking bar 2 by it is described first lock 3 lock end
Portion 33 limits, and the abutting end 52 of second lock 5 is resisted against on the extrados of first lock 3, when first lock
When 3 rotation of button, second lock 5 abuts end 52 along the extrados sliding of first lock 3, second lock 5
Clamped position is turned to by initial position under the promotion of first lock 3, in the clamped position, and described second latches
5 abutting end 52 is caught in into the notch 34 of first lock 3, to limit the rotation of first lock 3.
The force end 53 of second lock 5 is pushed by the push rod device 7, so that second lock 5 is by card
Coincidence sets rotation to initial position, and the abutting end 52 of second lock 5 is detached from the notch 34 of first lock 3, releases
Rotation limitation to first lock 3.
