Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent. It will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Referring to fig. 1 to 5 a shown lock core device, including lock core 1 and lock core cover 2, lock core 1 is located in lock core cover 2 to can lock core cover 2 rotate relatively, accommodation space 11 has been seted up to lock core 1's inside, be equipped with a plurality of locking plates 3 and the spacer 4 that are alternate interval arrangement in the accommodation space 11, the middle part of locking plate 3 and spacer 4 is left and is supplied key male through-hole, be equipped with elastic component 5 on the spacer 4, so that when unblanking, locking plate 3 pivoted drives elastic component 5 and takes place elastic deformation simultaneously, and produced reaction force makes when the shutting, elastic component 5 drives locking plate 3 and resets. Specifically, the number of the locking pieces 3 and the number of the spacers 4 are equal, and the elastic pieces 5 correspond to the spacers 4 one by one.

Preferably, the side wall of the lock core 1 is provided with a mounting groove 12, the outer side wall of the spacer 4 is provided with a positioning piece 41 extending into the mounting groove 12, and the positioning piece 41 abuts against the side wall of the mounting groove 12, so that the rotation of the spacer 4 is limited. The outer side wall of the locking plate 3 is provided with a limiting member 31 extending into the mounting groove 12 to limit the rotation angle of the locking plate 3.

Preferably, one end of the elastic member 5 is connected to the positioning member 41, and the other end of the elastic member 5 abuts against the limiting member 31, so that the elastic member 5 is pressed and deformed by the limiting member 31 in the unlocking state. Specifically, an avoiding groove 411 for accommodating the elastic member 5 is reserved at the positioning member 41 of the spacer 4, and one end of the elastic member 5 is connected with an inner side wall of the avoiding groove 411. Under the locking state, elastic component 5 is in the natural state, and locating part 31 is in one side of the junction of keeping away from elastic component 5 and setting element 41 of mounting groove 12, at the in-process of unblock, drives locking plate 3 through the key and rotates around its central axis, drives locating part 31 towards the opposite side motion of mounting groove 12, and then compresses corresponding elastic component 5, and elastic component 5 produces the reaction force to locating part 3 under the state of compressed, makes locking plate 3 and spacer 4 have the trend of doing relative reverse rotation motion.

For the quantity that reduces assembly spare part to the equipment of tool to lock, be integrative injection moulding structure between elastic component 5, setting element 41 and the spacer 4, be integrative injection moulding structure between locating part 31 and the locking plate 3.

The elastic piece 5 is of a sheet-shaped structure and is bent into an arc shape along the circumferential direction of the spacer 4, wherein the elastic piece 5 is designed into an arc-shaped sheet-shaped structure, so that the elastic piece has good resilience and is not easy to break.

Breach 6 has all been seted up to the lateral wall of locking plate 3 and spacer 4, and under the state of unblanking, breach 6 of each locking plate 3 and spacer 4 aligns each other to form the unlocking groove. The side wall of the lock cylinder 1 is provided with a through containing groove 13, a locking piece 7 is arranged in the containing groove 13, the inner side wall of the lock cylinder sleeve 2 is provided with a locking groove 21, in a locking state, the locking piece 7 is staggered with the unlocking groove and is partially embedded into the locking groove 21, and the rest part is positioned in the containing groove 13, so that the relative rotation of the lock cylinder 1 and the lock cylinder sleeve 2 is limited, and a locking effect is achieved; in the unlocking state, the locking piece 7 is partially inserted into the unlocking groove and is staggered with the locking groove 21, so that the relative rotation of the lock cylinder 2 and the lock cylinder sleeve 3 is released, and the unlocking is realized. It should be noted that the locking member 7 is preferably of a cylindrical structure. As a further refinement, the cross-section of the recess 6 and of the locking groove 21 is curved in order to facilitate the insertion or the offset of the locking element 7.

The inside wall of locking plate 3 is equipped with the guide block 32 that extends to its axis direction, and at the in-process of inserting the key, guide block 32 is along the guide way relative motion on the key, and then makes the locking plate rotate towards the unblock direction around its central axis. Since the structure of the key is a widely used prior art, the present invention does not further describe the structure.

In order to prevent the locking plate 3 and the spacer 4 from staggering the accommodating space 11, a lock cylinder cover 8 is arranged at the opening of the accommodating space 11, and the lock cylinder cover 8 is detachably and fixedly connected with the lock cylinder 1.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
