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. 1-8, an embodiment of the present utility model is provided: a lockset, which comprises a lock shell 1, a lock tongue 2 in sliding fit with the lock shell 1 and an actuating mechanism 3 arranged in the lock shell 1; the actuating mechanism 3 is connected with the lock tongue 2 through a connecting rod 6, and the locking device can complete unlocking or locking through the work of the actuating mechanism 3; the actuating mechanism 3 comprises a first shifting piece 33 and a second shifting piece 34, and the first shifting piece 33 and the second shifting piece 34 are linked with the connecting rod 6 when rotating in the unlocking direction so as to drive the lock tongue 2 to slide into the lock shell 1, so that the lock can complete unlocking action; when the first pulling piece 33 or the second pulling piece 34 rotates in the unlocking reverse direction, the first pulling piece 33 or the second pulling piece 34 drives the lock tongue 2 to slide outwards from the inside of the lock shell 1, so that the lock is switched to an up-locking action.

In summary, the actuating mechanism 3 is utilized to promote the lock tongue 2 to slide in the lock shell 1, so that the lock can complete unlocking and unlocking actions, and the operation of the lock is simple and convenient, and especially, the structure of the lock can be simplified, and the unlocking actions or unlocking actions are realized, and meanwhile, the structure is simplified, so that the production cost of the lock is reduced.

Further, the actuating mechanism 3 further includes a linkage member 35 for implementing linkage between the first shifting piece 33 and the second shifting piece 34, and the linkage member 35 is linked with a locking member 32 provided in the lock case 1; the linkage member 35 follows the linkage of the first shifting piece 33 or the second shifting piece 34, so that the locking member 32 limits the sliding of the connecting rod 6 to the lock shell 1 or releases the limitation of the sliding of the connecting rod 6 by the locking member 32.

When the first shifting sheet 33 or the second shifting sheet 34 is shifted clockwise to rotate, the linkage piece 35 is driven to drive the locking piece 32 to rotate anticlockwise, and then the locking piece 32 is prevented from sliding downwards by the connecting rod 6, so that the two shifting sheets retract the lock tongue 2 connected with the connecting rod 6 into the lock shell 1, and unlocking action is completed;

When the lock tongue 2 extends out of the lock shell 1 and then rotates the first pulling piece 33 anticlockwise, the linkage piece 35 drives the locking piece 32 to rotate clockwise until the upper end of the locking piece 32 is located at the bottom of the connecting rod 6, at this time, the locking piece 32 abuts against the connecting rod 6 to limit the connecting rod 6 to move downwards, and the connecting rod 6 can be prevented from moving downwards by the locking piece 32, so that locking of the lock tongue 2 is achieved.

The specific application is as follows: when the first pulling piece 33 is connected with the door inner handle, the door inner handle can be utilized to enable the first pulling piece 33 to rotate, and similarly, the door outer handle is utilized to enable the second pulling piece 34 to rotate, so that when the door outer handle or the door inner handle rotates, the locking piece 32 can be driven to be separated from the connecting rod 6, the connecting rod 6 is enabled to enable the lock tongue 2 to retract into the lock shell 1 under the action of the first pulling piece 33 or the second pulling piece 34, then the door inner handle or the door outer handle is enabled to rotate upwards, at the moment, the first pulling piece 33 or the second pulling piece 34 can enable the locking piece 32 to be driven to approach to the bottom of the connecting rod 6, the connecting rod 6 is prevented from continuously sliding downwards, and further the lock tongue 2 is prevented from moving inwards the lock shell 1, so that the door lock is locked.

In summary, after the lock is mounted on the door, the handle outside or inside the door is rotated downward, so that the lock can be unlocked, and at the same time, the back locking action of the device can be realized by rotating the handle inside or outside the door upward.

In order to reliably drive the first shifting piece 33 and the second shifting piece 34 to follow the two shifting pieces to link, the first shifting piece 33 and the second shifting piece 34 are respectively provided with a first protruding portion 36, and when the first protruding portion 36 contacts with a first connecting portion 38 arranged on the linkage piece 35, one end of the locking piece 32 is driven by the linkage piece 35 to move to the bottom of the connecting rod 6, and downward movement of the connecting rod 6 is limited. Specifically, the first connecting portion 38 extends to two sides of the linkage member 35, so when two or one of the dials is rotated, the first protruding portion 36 on the two dials or one of the dials is contacted with the two or one of the dials to drive the linkage member 35 to rotate, so as to promote the locking member 32 to prevent the connecting rod 6 from moving into the lock case 1.

In order to avoid the phenomenon that the locking state and the unlocking state of the lock are uncontrolled due to the autorotation of the linkage piece 35 or the two pulling sheets; the first connecting portion 38 is further provided with a limiting member 30, and the limiting member 30 is connected with the limiting hole 5 provided on the lock case 1 in an adaptive manner, so that the rotation of the linkage member 35 is limited by the limiting member 30. Therefore, the limiting piece 30 can be connected with the limiting hole 5, so that the fixing of the linkage piece 35 is realized, and the rotation of the linkage piece 35 is prevented, and the rotation of the two shifting sheets under the action of no external force can be prevented.

Further, the number of the limiting holes 5 is two, one of the limiting holes is used for fixing the linkage piece 35 in the locking state, and the other limiting hole is used for fixing the linkage piece 35 in the unlocking state; based on the method, the lock can keep lasting and reliable locking action when in a locking state; when the lockset is in an unlocking state, the phenomenon of automatic locking can not occur.

Furthermore, since the elastic member is further disposed in the first connecting portion 38, and the limiting member 30 is urged to abut against the limiting hole 5 by the elastic member, the elastic member can be utilized to reliably urge the limiting member 30 to abut against the limiting hole 5, so that the lock can be further ensured to be stable and reliable in the locked state or the unlocked state, and the problem that the locked state and the unlocked state are interchanged without intervention is avoided. In addition, in order to reduce the resistance of the stopper 30 when moving between the two stopper holes 5, the stopper 30 is provided in a spherical shape, and the elastic member is preferably a spring.

In order to improve the safety of the lock, the linkage member 35 is further provided with a second connecting portion 39, and is connected with the fastener 31 provided with the second connecting portion 39, so that the linkage member 35 rotates along with the first dial 33. Specifically, when the first pulling piece 33 rotates clockwise, until the first protruding portion 36 abuts against the fastening piece 31, the linkage piece 35 can be driven to rotate clockwise along with the continued rotation of the first pulling piece 33, and at this time, the linkage piece 35 drives the locking piece 32 to rotate anticlockwise, so that the locking piece 32 is separated from the bottom of the connecting rod 6, and the connecting rod 6 drives the lock tongue 2 to retract into the lock case 1 to complete the unlocking action.

Based on this, the unlocking action of the lock can be completed through the first shifting piece 33, and the second shifting piece 34 cannot trigger the unlocking action because the fastening piece 31 is not contacted with the second shifting piece 34; when the first pulling piece 33 is connected with the door inner handle, the lock can complete unlocking action in the door, unlocking of the lock can not be achieved outside the door, and therefore safety of the lock is improved.

Further, since the lock housing 1 is further provided with a through hole 4 that completely penetrates through the lock housing 1, and the fastening member 31 is movably connected with the second connecting portion 39 after penetrating through the through hole 4, the unlocking direction of the lock can be adjusted by inserting the fastening member 31 from different sides of the lock housing 1. For example, after the fastener 31 is inserted into the linkage 35 from the left side of the lock case 1, the unlocking operation can be completed only when the first dial 33 is rotated clockwise; on the contrary, when the fastener 31 is inserted from the right side of the lock case 1, the first pulling piece 33 can only complete the unlocking action of the lock when rotated counterclockwise. Based on this, the unlocking direction of the first paddle 33 can be adjusted adaptively according to the needs of the user. The fastening member 31 is preferably a bolt, and is screwed with the second connecting portion 39.

On the basis of the above scheme, since the linkage member 35 and the locking member 32 are in gear transmission, specifically, the facing surfaces of the linkage member 35 and the locking member 32 are provided with racks and tooth grooves, and the gear transmission between the linkage member 35 and the locking member 32 is completed by utilizing the engagement of the racks and the tooth grooves. Based on the above, the phenomenon that the linkage member 35 and the locking member 32 slip during power transmission can be prevented by utilizing the engagement of the gear and the tooth groove, so that the reliable transmission of power is ensured, and the engagement of the gear and the tooth groove also has a reliable stopping effect.

Further, in order to ensure that the two paddles can reliably promote the movement of the connecting rod 6, the first paddle 33 and the second paddle 34 are connected with the connecting rod 6 through second protruding parts 37 arranged on the first paddle 33 and the second paddle 34, so that the first paddle 33 and the second paddle 34 promote the downward movement of the connecting rod 6 from two sides of the connecting rod 6, and the lock tongue 2 is promoted to slide into the lock case 1. Specifically, the bottom of the connecting rod 6 is further provided with a protruding portion extending to the side surface of the connecting rod 6, and at this time, the first pulling piece 33 is in contact with the protruding portion on the inner side of the connecting rod 6; the second pulling piece 34 contacts with the protruding part on the outer side of the connecting rod 6, so that the first pulling piece 33 or the second pulling piece 34 can reliably promote the connecting rod 6 to move downwards, thereby ensuring the stable and reliable inward contraction of the lock tongue 2 to the lock shell 1. In addition, by extending the lengths of the first shifting piece 33 and the second shifting piece 34, the two shifting pieces can reliably promote the connecting rod 6 to move, so that the phenomenon that the two shifting pieces slip to cause unlocking failure or unlocking inequality during rotation is avoided.

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.
