Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 5, a locking device includes a lock base 1, the lock base 1 is provided with at least one locking notch 11, a lock cylinder 3 and a locking elastic member 4 for locking a locked body 2 are arranged in the locking notch 11, when the locked body 2 is placed in the locking notch 11, the lock cylinder 3 can lock the locked body 2, and when the lock cylinder 21 locks the locked body 2, the locking elastic member 4 has a pre-tightening force for ejecting the locked body 2 out of the locking notch 11.

The utility model discloses in, because lock elastic component 4 has and will be popped out by lock body 2 the pretightning force of fore shaft 11 works as lock core 3 will be by 2 unblocks backs of lock body, the pretightning force of locking elastic component 4 can pop out fore shaft 11 by lock body 2, specifically see figure 5. The utility model discloses for prior art does not adopt lock elastic component 4, can help the people to clearly see whether locking device will be locked by lock body 2, avoid appearing falling into fore shaft 11 by lock body 2, and do not have the condition by 3 locking of lock core. When will be locked again after 2 unblocks of lock body, will be placed by lock body 2 in the fore shaft 11, press and overcome by lock body 2 after the elastic force of locking elastic component 4 falls into to suitable position, will lock core 3 toward will be locked the direction motion by lock body 2 and then will be locked by lock body 2 can, at this moment, lock elasticity department 4 is in elastic deformation state, when unblanking again, can expose to fore shaft 11 by 2 bounces of lock body once more.

As a further aspect of the present invention: referring to fig. 2 and 8, the locking device includes a plurality of locking notches 11, a pushing block 5 and an elastic member 6, the pushing block 5 moves in both directions relative to the locking notches 11, when the pushing block 5 moves relative to the lock cylinder 3, the pushing block 5 can touch the lock cylinders 3 of all the locking notches, when the pushing block 5 moves in a forward direction and touches the lock cylinder 3 in one of the locking notches, the pushing block 5 can avoid the lock cylinder 3, specifically see fig. 9; when the pushing block 5 moves reversely and touches the lock cylinder 3 of one of the locking notches 11, the pushing block 5 pushes the lock cylinder 3 to move so as to unlock the locked body 2; see in particular fig. 10; the elastic piece 6 has a pre-tightening force for enabling the lock cylinder 3 to be in a locking state, preferably, the elastic piece 6 is fixed on the lock seat 1, and one end, extending out, of the elastic piece 6 is in contact with the lock cylinder 3.

In the scheme, as shown in fig. 9, when the pushing block 5 moves forward to touch the lock cylinder 3, the pushing block 5 can avoid the lock cylinders 3 of all the locking openings 11, so that when the pushing block 5 moves forward, one of the locking openings 11 can be selected from the plurality of locking openings 11, then the lock cylinder is unlocked, when one of the locking openings is unlocked, as shown in fig. 10, the pushing block 5 moves in a reverse direction to touch the lock cylinder 3 of the locking opening 11, and at this time, the movement of the pushing block 5 can drive the lock cylinder 11 to move in the direction of unlocking the lock body 2. In the above structure, the unlocking of the plurality of locking openings 11 can be realized only by one unlocking driving device (i.e., the pushing block 5), and when one locking opening 11 is unlocked, the state of other locking openings is not affected. When the lock needs to be locked again after unlocking is finished, the pushing block 5 is moved to the position of the lock cylinder 3 separated from the lock opening 11, and at the moment, the lock cylinder 3 returns to the position capable of locking the locked body 2 under the action of the elastic piece 6;

preferably, referring to fig. 8 to 10, the pushing block 5 includes a pushing slider 51 and a pushing rotating block 52, the pushing slider 51 slides in two directions relative to the locking notch 1, the pushing rotating block 52 is rotatably connected to the pushing slider 51, a limiting portion 511 is disposed on the pushing slider 51, the limiting portion 511 can be touched when the pushing rotating block 52 rotates, when the pushing rotating block 52 touches the limiting portion 511, the limiting portion 511 is used for limiting the pushing rotating block 52 to rotate towards the limiting portion 511, a return spring 53 is disposed between the pushing slider 51 and the pushing rotating block 52, and the return spring 53 is used for maintaining a pre-tightening force of the pushing rotating block 52 contacting the limiting portion 511; the lock cylinder 3 is provided with a touch part 31, when the push slider 51 slides in two directions, the push rotating block 52 can touch the touch part 31, when the push slider 51 slides in the forward direction and the push rotating block 52 touches the touch part 31, the push rotating block 52 can rotate to avoid the touch part 31, as shown in fig. 9 specifically; when the pushing slider 51 slides reversely and the pushing rotating block 52 touches the touch portion 31, the limiting portion 511 limits the pushing rotating block 52 to rotate and the pushing rotating block 52 drives the lock cylinder 3 to slide in the unlocking direction through the touch portion 31, as shown in fig. 10.

Preferably, referring to fig. 8 and 11, the sliding of the push slider 51 is realized by a screw mechanism 7, the screw mechanism 7 includes a motor 71 and a screw 72, the screw 72 is in threaded connection with the push slider 51, and the lock base 1 is provided with a rotation limiting portion 12 for limiting the rotation of the push slider 51. In this embodiment, when the screw 72 rotates, the rotation limiting portion 12 limits the rotation of the pushing slider 51, so that the pushing slider 51 can slide along the screw 72.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
