The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-6, an embodiment of the present utility model provides a door lock, which includes a lock case 1, wherein the lock case 1 is connected to a door body through a fixing member 6 provided thereon, and the lock case 1 rotates on the fixing member 6 and is connected to a slot 7 provided on the fixing member 6 in an adaptive manner through a latch 3 provided thereon, so as to prevent the rotation of the lock case 1 on the fixing member 6.

In summary, the locking action of the lock can be realized by using the connection of the bolt 3 and the slot 7, otherwise, the bolt 3 is separated from the slot 7 to ensure that the lock completes the unlocking action, so that the operation is simpler and more convenient while the locking action and the unlocking action of the lock are simplified, and compared with the prior art, the utility model has the advantages of novel structure, simple and convenient operation, good locking effect and stable and reliable locking capability by using the cooperation of the bolt 3 and the slot 7 to enhance the locking capability of the lock after locking, thereby solving the problem that the existing ecological lock is poor in security and easy to be opened.

Furthermore, a support column 8 is further arranged on one surface of the lock shell 1 facing the fixing piece 6, a reset piece 9 is sleeved on the support column 8, and the reset piece 9 is used for promoting the reset of the lock shell 1 after rotation, so that the lock shell 1 can be quickly reset under the action of the reset piece 9 after each rotation, the reset piece 9 is preferably a torsion spring, wherein both ends of the torsion spring are clamped on the support column 8, meanwhile, a protruding portion 15 is further arranged on the back surface of the fixing piece 6, a slot 7 is formed in the protruding portion 15, the protruding portion 15 enables the torsion spring to rotate when the lock shell 1 rotates, the torsion spring resets after the external force of the lock shell 1 disappears, the lock shell 1 is driven to reset, in addition, the lock shell 1 is long-strip-shaped, and the cross section of the lock shell 1 in a plan view is L-shaped.

On the basis of the scheme, in order to facilitate the smooth connection or the smooth separation of the plug pin 3 and the slot 7 by a user, a sliding piece 4 is further arranged inside the lock shell 1, and the sliding piece 4 slides in the lock shell 1 to facilitate the plug pin 3 to be inserted into the slot 7 or the plug pin 3 to be separated from the slot 7, so that the sliding piece 4 slides in the lock shell 1 to facilitate the connection or the separation of the plug pin 3 and the slot 7.

Furthermore, the elastic piece 2 is further arranged on the bolt 3, and the bolt 3 is separated from the slot 7 by the sliding piece 4 after being separated from the bolt 3, so that the bolt 3 is convenient to reset when unlocking, and one end of the bolt 3 far away from the slot 7 can be reliably abutted against the sliding piece 4 when locking, so that the locking state of the lockset can be kept for a long time. The elastic member 2 is preferably a coil spring, and in addition, the lock housing 1 is provided with a mounting cavity 14, wherein one end of the elastic member 2 abuts against the mounting cavity 14, and the other end abuts against the latch 3, so that the latch 3 can rapidly slide towards the inside of the lock housing 1 after being separated from the sliding member 4, so as to complete unlocking of the lock.

Furthermore, since the sliding piece 4 is further provided with the shifting block 13, and the shifting block 13 passes through the lock shell 1 and then faces the door body, a user can dial the shifting block 13 by fingers to drive the sliding piece 4 to slide in the lock shell 1, so that the user can simply and conveniently complete the locking or unlocking action of the lockset outside the lock shell 1.

Meanwhile, since the sliding groove 11 for guiding the sliding piece 4 to slide is further provided in the lock case 1 and is connected with the lock case 1 through the provided cover plate 5 so as to cover the sliding piece 4 in the sliding groove 11, the cover plate 5 can be used for limiting the sliding piece 4 in the sliding groove 11, so that the sliding piece 4 can only directionally slide, the reliability of the linkage of the sliding piece 4 and the bolt 3 is further improved, and the sliding piece 4 can be conveniently used for reliably unlocking or reliably unlocking the lockset.

In order to facilitate smooth sliding of the bolt 3 to the outside of the lock case 1 or sliding of the bolt 3 into the lock case 1, a boss 12 is further provided on the sliding member 4, and one end of the bolt 3 facing the sliding member 4 slides on the boss 12, so when the sliding member 4 contacts with the bolt 3 in the sliding process, the bolt 3 is pushed up to facilitate the bolt 3 to be inserted into the slot 7 to complete the locking action as the sliding member 4 continues to slide until the highest point of the boss 12 contacts with the bolt 3, otherwise, the boss 12 is gradually separated from one end of the bolt 3 in the resetting process of the sliding member 4, and the bolt 3 continuously slides into the lock case 1 under the action of the elastic member 2 until the other end of the bolt 3 is completely separated from the slot 7 to complete the unlocking action as the bolt 3 slides to the lowest point of the boss 12.

Furthermore, one end of the bolt 3 is arranged in a hemispherical shape, and the boss 12 is further provided with a stop groove 10, so that after the hemispherical bolt 3 is released from the stop groove 10, the sliding resistance of the bolt 3 can be improved, the phenomenon that the bolt 3 is automatically separated from the slot 7 is avoided, and furthermore, as the number of the bolts 3 is equal to that of the bosses 12, for example, the number of the bolts 3 is two and the bolts are symmetrically arranged at two ends of the support column 8, at the moment, the two bolts 3 are connected with the slot 7, so that the contact point between the lock shell 1 and the fixing piece 6 is increased, and the locking capability of the lock after locking is further enhanced.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
