Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. 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 is provided: a lock with a reversible lock tongue, which comprises a lock shell 1 and a lock tongue 2 sliding on the lock shell 1; wherein, the inside of the lock shell 1 is also provided with a linkage rod 3, and one end of the linkage rod 3, which is far away from the inside of the lock shell 1, is rotationally connected with the lock tongue 2; the toggle piece 7 is arranged to drive the linkage rod 3 to drive the lock tongue 2 to slide into the lock shell 1 so as to complete the unlocking action of the lockset; the elastic piece 6 drives the linkage rod 3 to drive the lock tongue 2 to slide towards the outside of the lock shell 1 so as to complete the locking action of the lockset.

In summary, when the lock tongue 2 needs to be changed in direction, that is, the inclined plane of the lock tongue 2 faces outwards or inwards, the linkage rod 3 is pushed outwards until the lock tongue 2 is completely separated from the lock shell 1, and then the inclined plane of the lock tongue 2 can be adjusted to a required position as required by rotating the lock tongue 2. In particular, the bolt 2 can be directly rotated by hand without disassembling the lock case 1, so that the direction change of the bolt 2 can be realized, the door lock is more convenient and quick to install, and meanwhile, the labor cost and the time cost are saved.

In order to facilitate the adjustment of the direction of the lock tongue 2 by the user, a limiting piece 13 is further provided in the lock case 1, and the linkage rod 3 is caused to cause the lock tongue 2 to slide towards the outside of the lock case 1 by the separation of the limiting piece 13 and the linkage rod 3. Based on the fact, the user presses the limiting piece 13, at the moment, the limiting piece 13 is separated from the linkage rod 3, under the action of the elastic piece 6, the linkage rod 3 is caused to push the lock tongue 2 to slide to the outside of the lock shell 1 completely, and at the moment, the user only needs to rotate the lock tongue 2, and adjustment of the direction of the lock tongue 2 can be completed.

Further, since the lock case 1 is further provided with the driving rod 12, and the limiting piece 13 is urged to be separated from the linkage rod 3 by the driving rod 12, the limiting piece 13 can be urged to be separated from the linkage rod 3 by pressing the driving rod 12 outside the lock case 1, wherein when the limiting piece 13 is a spring piece, the driving rod 12 can be urged to be reset and the spring piece can be urged to be in contact with the linkage rod 3 after being reset, so as to limit the sliding travel of the linkage rod 3, and further prevent the lock tongue 2 from completely sliding outside the lock case 1.

Furthermore, the linkage rod 3 is further provided with a step surface 10, and the sliding travel of the linkage rod 3 is limited by the step surface 10 abutting against the side surface of the limiting piece 13. Therefore, the step surface 10 can be used for being abutted against the limiting piece 13 so as to limit the sliding travel of the linkage rod 3, and further the problem that the lock tongue 2 automatically turns due to sliding out of the lock shell 1 can be avoided. Specifically, after the limiting piece 13 resets, the lock tongue 2 is pushed inwards, the limiting piece 13 which is sprung upwards is contacted with the step surface 10 on the linkage rod 3 again, and at the moment, the sliding stroke of the lock tongue 2 can be reduced while the locking action of the lock is not influenced, so that the problem that the lock tongue 2 is completely separated from the lock shell 1 to automatically turn is avoided.

Meanwhile, since the end of the limiting piece 13 far away from the linkage rod 3 is fixed on the supporting frame 11 arranged in the lock shell 1, the limiting piece 13 can be reliably positioned in the lock shell 1 to improve the reliability of the limiting piece 13 during working, in particular, the supporting plate 11 is arranged, and when the step surface 10 is abutted to the supporting frame 11, the outward sliding distance of the lock tongue 2 can be limited.

In summary, through the rotation of the toggle member 7, the lock tongue 2 is driven to retract inward toward the lock case 1, so as to complete the unlocking action of the lock, after the external force driving the rotation of the toggle member 7 disappears, the elastic member 6 drives the linkage rod 3 to slide outward until the step surface 10 abuts against the side surface of the limiting member 13, and at this time, the lock tongue 2 extends out of the lock case 1, so as to realize the multiple actions of the lock; meanwhile, the step surface 10 can limit the lock tongue 2 to slide outwards when contacting with the limiting piece 13; so as to ensure that the lock tongue 2 normally completes locking or unlocking actions on the lock shell 1.

When the lock tongue 2 needs reversing, the driving rod 12 is pressed, the limiting piece 13 is made to be separated from the step surface 10, the elastic piece 6 is made to enable the linkage rod 3 to slide outwards until the step surface 10 abuts against the supporting plate 11, the lock tongue 2 is completely separated from the lock shell 1, and the direction conversion of the lock tongue 2 can be completed by rotating the lock tongue 2.

In order to solve the phenomenon that the lock tongue 2 falls off each other in the rotating process or in the sliding process and the linkage rod 3, the linkage rod 3 is further provided with a protruding portion 4, and the protruding portion 4 is rotationally connected with a shaft pin hole 5 arranged in the lock tongue 2, so that the protruding portion 4 can be inserted into the shaft pin hole 5 to limit the falling off phenomenon of the lock tongue 2 and the linkage rod 3, and meanwhile, after the protruding portion 4 is connected with the shaft pin hole 5, the stability of the lock tongue 2 after being connected with the linkage rod 3 is ensured, and the falling off phenomenon of the lock tongue 2 and the linkage rod 3 during working can be effectively avoided.

In order to promote the reliable contact between the elastic piece 6 and the poking piece 7 and between the elastic piece 6, so as to ensure that the poking piece 7 can reliably drive the linkage rod 3 to slide and the elastic piece 6 can reliably drive the linkage rod 3 to move outwards, the bottom of the linkage rod 3 is provided with a baffle plate 9; wherein, one surface of the baffle plate 9 is abutted against the poking piece 7, and the other surface of the baffle plate 9 is abutted against the elastic piece 6.

Specifically, the elastic member 6 is a torsion spring and is sleeved on the support column 8 arranged in the lock shell 1, so that the linkage rod 3 can be driven to slide outwards by the torsion spring, and part of the lock tongue 2 can be driven to be exposed outside the lock shell 1 after the external force disappears.

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.
