Referring to fig. 1, 2 and 3, a lock body 200 includes a lock case 10, a locking bolt 20, an unlocking assembly, a locking top 30 and a driving mechanism 40. The locking bolt 20 is movably disposed in the housing 10. The unlocking assembly comprises a first shifting block 50 and a second shifting block 60, the first shifting block 50 and the second shifting block 60 are both rotatably arranged on the lock shell 10, and the first shifting block 50 or the second shifting block 60 can drive the bolt 20 to move relative to the lock shell 10 in the unlocking direction. The locking top piece 30 is movably arranged in the lock case 10 along a first preset direction a (see fig. 11) and a second preset direction B, the locking top piece 30 has a first position and a second position in the first preset direction a, when the locking top piece 30 is located at the first position, the locking top piece 30 allows the second dial 60 to rotate in the unlocking direction and the locking top piece 30 to move back and forth along the second preset direction B to prevent or allow the first dial 50 to rotate in the unlocking direction, when the locking top piece 30 is located at the second position, the locking top piece 30 allows the first dial 50 to rotate in the unlocking direction and the locking top piece 30 to move back and forth along the second preset direction B to prevent or allow the second dial 60 to rotate in the unlocking direction, and the first preset direction a and the second preset direction B form a non-zero included angle. The driving mechanism 40 is configured to drive the locking top 30 to move along the second preset direction B, so that the locking top 30 prevents the first toggle mechanism 50 or the second toggle mechanism 60 from rotating towards the unlocking direction.

The locking top 30 has a first position and a second position in the first preset direction a, so that when the locking top 30 is located at the first position, the second dial 60 can always rotate relative to the lock case 10 in the unlocking direction and move the locking top 30 relative to the lock case 10 in the second preset direction B to prevent or allow the first dial 50 to rotate relative to the lock case 10 in the unlocking direction, so as to prevent or allow the first dial 50 to drive the locking bolt 20 to move relative to the lock case 10, and when the locking top 30 is located at the second position, the first dial 50 can always rotate relative to the lock case 10 in the unlocking direction and move the locking top 30 relative to the lock case 10 in the second preset direction B, so as to prevent or allow the second dial 60 to drive the locking bolt 20 to move relative to the lock case 10, thereby achieving locking and unlocking of the lock body 200. That is, when the lock body 200 is used in different usage environments with left-handed or right-handed doors, different usage environment requirements can be met by disposing the locking top 30 at the first position or the second position, when the lock body 200 is used in a usage environment with a left-handed door, the locking top 30 needs to be disposed at the first position so that the second toggle 60 located inside the door is always rotatable relative to the lock case 10, and the driving mechanism 40 can drive the locking top 30 to move in the second preset direction B to lock the first toggle 50, when the lock body 200 is used in a usage environment with a right-handed door, the locking top 30 needs to be disposed at the second position so that the first toggle 50 located inside the door is always rotatable relative to the lock case 10, and the driving mechanism 40 can drive the locking top 30 to move in the second preset direction B to lock the second toggle 60, therefore, the lock body 200 with the structure can be suitable for different use environments, and the lock bodies 200 of various models do not need to be produced aiming at different use environments, so that the universality of the lock body 200 is greatly improved, and the inventory of accessories of a production line is reduced.

It should be noted that the first dial 50 and the second dial 60 are respectively used for connecting two door handles located at two sides of the door, so that the two door handles located at two sides of the door can respectively drive the first dial 50 and the second dial 60 to rotate relative to the lock case 10, so as to open the door. First shifting block 50 and second shifting block 60 arrange in lock shell 10 relatively, and the direction at first shifting block 50 and second shifting block 60's axis of rotation place all is the same with first preset direction A, as shown in fig. 3, and the unblock direction is clockwise, and when first shifting block 50 or second shifting block 60 rotate clockwise relatively lock shell 10, first shifting block 50 or second shifting block 60 can drive spring bolt 20 and remove relatively lock shell 10 to realize unblanking of lock body 200.

The first preset direction a is perpendicular to the second preset direction B. By arranging the first preset direction a and the second preset direction B perpendicularly, the phenomenon that the first shifting block 50 or the second shifting block 60 is unlocked or locked by mistake due to the interference area when the locking top piece 30 is switched between the first position and the second position and moves back and forth in the second preset direction B is avoided.

In this embodiment, as shown in fig. 2 and 4, the lock case 10 includes a first case 11 and a second case 12, the first case 11 covers the second case 12, and the first case 11 is detachably connected to the second case 12 by bolts. Referring to fig. 4 and 5, a first mounting hole 111 is formed in the first housing 11, and the first toggle member 50 is rotatably disposed in the first mounting hole 111. Referring to fig. 1 and 4, a second mounting hole 121 is formed in the second housing 12, and the second toggle member 60 is rotatably disposed in the second mounting hole 121.

Furthermore, a reversing hole 13 for inserting the driving rod is formed on the lock shell 10. The drive lever is used to drive the locking tip 30 to switch between the first position and the second position.

In addition, in the process that the driving assembly 42 drives the locking slider 41 to move from the unlocking position to the locking position, the locking slider 41 can push the locking ejector 30 to move towards the direction close to the first shifting block 50 and the second shifting block 60 along the second preset direction B, so that the resetting function of the locking ejector 30 is realized, other structures are not required to be arranged to realize the resetting function of the locking ejector 30, the production cost of the lock body 200 is saved, and the floor space of the lock body 200 is reduced.

The third preset direction C is perpendicular to the first preset direction a and forms a non-zero included angle with the second preset direction B. The moving direction of the locking bolt 20 is the same as the third preset direction C.

Further, the locking slider 41 has a guiding inclined plane, the guiding inclined plane is used for the locking top 30 to abut against, when the driving assembly 42 drives the locking slider 41 to move from the unlocking position to the locking position, the locking top 30 abuts against the guiding inclined plane, so that the guiding inclined plane arranged on the locking slider 41 drives the locking top 30 to move along the second preset direction B toward the direction far away from the locking slider 41, thereby realizing the resetting function of the locking top 30.

In some embodiments, as shown in fig. 2 and 3, the driving assembly 42 may include a driving member 421 and a transmission assembly 422, wherein the driving member 421 is in transmission connection with the locking slider 41 through the transmission assembly 422, so as to drive the locking slider 41 to move along the third predetermined direction C through the driving member 421.

Illustratively, the drive member 421 is an electric motor. In other embodiments, the driving member 421 may be a hydraulic motor.

Further, as shown with continued reference to fig. 2 and 3, the transmission assembly 422 includes a transmission rod 4221, a drive spring, a movable block 4222, and a connecting rod 4223. The transmission rod 4221 is connected to an output shaft of the driving member 421, the driving member 421 is used for driving the transmission rod 4221 to rotate relative to the lock shell 10, and the extension direction of the transmission rod 4221 is consistent with the third preset direction C. The driving spring is sleeved outside the driving rod 4221, a clamping column clamped on the driving spring is arranged on the driving rod 4221, and the clamping column is clamped in a gap between two adjacent circles of the driving spring. The movable block 4222 is movably sleeved outside the transmission rod 4221 along a third preset direction C, a placing groove is formed in the movable block 4222, the driving spring is located in the placing groove, and two side groove walls opposite to the placing groove are used for the driving spring to abut against. Both ends of the connecting rod 4223 are connected to the locking slider 41 and the movable block 4222, respectively.

When the driving member 421 drives the transmission rod 4221 to rotate forward or reversely, the transmission rod 4221 can make the driving spring abut against two opposite side groove walls of the placement groove to drive the movable block 4222 to move back and forth in the third preset direction C relative to the lock shell 10, so as to drive the locking slider 41 to move between the unlocking position and the locking position through the connecting rod 4223, and thus, the locking slider 41 is switched between the unlocking position and the locking position.

It should be noted that, in other embodiments, the driving assembly 42 may also be in other structures, for example, the driving assembly 42 is an air cylinder, a cylinder body of the air cylinder is fixedly disposed in the lock case 10, and the locking slider 41 is connected to an output end of the air cylinder, so that the locking slider 41 is driven by the air cylinder to switch between the unlocking position and the locking position.

In this embodiment, the lock body 200 further includes an actuator. The actuator has a normally closed state and a normally open state. When the actuator is in the normally closed state and the locking top 30 is located at the first position, the locking top 30 moves back and forth along the second preset direction B to prevent or allow the first shifting block 50 from rotating towards the unlocking direction. When the actuator is in the normally closed state and the locking top 30 is in the second position, the locking top 30 moves back and forth in the second preset direction B to prevent or allow the second dial 60 from rotating in the unlocking direction. When the actuator is in a normally open state, the locking top 30 can allow the first shifting block 50 and the second shifting block 60 to rotate towards the unlocking direction.

Switching between the normally open state and the normally closed state of the lock body 200 is achieved by providing an actuator in the lock body 200, that is, when the actuator is in the normally closed state, locking or unlocking of the first dial 50 or the second dial 60 can be achieved by the reciprocal movement of the locking top 30 in the second preset direction B, thereby achieving locking and unlocking of the lock body 200. When actuating mechanism is in normally open state, first shifting block 50 and second shifting block 60 do not all receive the effect of locking ejector member 30 to make first shifting block 50 and second shifting block 60 homoenergetic rotate to the unblock direction relatively lock shell 10, thereby realize the normally open state of lock body 200, make two handles homoenergetic rotations that are used for connecting in first shifting block 50 and second shifting block 60, and then drive the relative lock shell 10 of spring bolt 20 and remove, in order to open the door.

Further, as shown in connection with fig. 3 and 7, the actuator includes a ram core 70. The poking rod core 70 is rotatably arranged on the lock shell 10, the rotation axis of the first poking head 50, the rotation axis of the second poking head 60 and the rotation axis of the poking rod core 70 are overlapped, and an avoiding groove 71 is arranged on the peripheral wall of the poking rod core 70. The lock body 200 further comprises a first moving member 80 and a second moving member 90, wherein the first moving member 80 is movably disposed on the first dial 50, and the second moving member 90 is movably disposed on the second dial 60. When the actuating mechanism is in a normally closed state and the locking top piece 30 is located at the first position, the avoiding groove 71 is staggered with the first moving piece 80, so that the dial rod core 70 can prevent the first moving piece 80 from moving into the avoiding groove 71, and the locking top piece 30 can block the first moving piece 80 when moving in the direction close to the first moving piece 80 along the second preset direction B, so that the first dial 50 is prevented from rotating in the unlocking direction. When the actuating mechanism is in the normally closed state and the locking top piece 30 is located at the second position, the avoiding groove 71 is staggered from the second moving piece 90, so that the dial rod core 70 can prevent the second moving piece 90 from moving into the avoiding groove 71, and the locking top piece 30 can block the second moving piece 90 when moving in the direction close to the second moving piece 90 along the second preset direction B, so as to prevent the second dial 60 from rotating in the unlocking direction. When the actuator is in a normally open state, the first moving member 80 and the second moving member 90 are aligned with the avoiding groove 71, so that the dial rod core 70 can allow the first moving member 80 and the second moving member 90 to move into the avoiding groove 71, and the first moving member 80 and the second moving member 90 can avoid the locking top member 30, so as to allow the first dial 50 and the second dial 60 to rotate in the unlocking direction.

The first shifting block 50 and the second shifting block 60 are respectively provided with a first moving member 80 and a second moving member 90 for blocking the locking top member 30, as shown in fig. 3 and 6, when the first moving member 80 and the second moving member 90 are staggered with the avoiding groove 71 of the shifting rod core 70, the first moving member 80 and the second moving member 90 are blocked by the outer peripheral wall of the shifting rod core 70 and cannot move into the avoiding groove 71, so that the first moving member 80 and the second moving member 90 can be abutted by the locking top member 30, and the locking sliding block 41 is driven by the driving assembly 42 to be switched between the unlocking position and the locking position to allow or prevent the first shifting block 50 or the second shifting block 60 from rotating in the unlocking direction, thereby locking and unlocking the lock body 200. Referring to fig. 3 and 8, when the first moving member 80 and the second moving member 90 are aligned with the avoiding groove 71 of the shift lever core 70, that is, the actuating mechanism is in a normally open state, the first moving member 80 and the second moving member 90 can move in the avoiding groove 71, so that the locking top member 30 cannot block the first moving member 80 and the second moving member 90, so that the first shift lever 50 and the second shift lever 60 are always in a state capable of rotating in the unlocking direction, and at this time, the lock body 200 cannot be locked.

As shown in fig. 7, the dialing rod core 70 is provided with an insertion hole 72, the insertion hole 72 is used for inserting the dialing rod, so that the dialing rod core 70 can be driven by the dialing rod to rotate relative to the lock housing 10, and the avoiding groove 71 of the dialing rod core 70 is aligned with or staggered from the first moving member 80 and the second moving member 90, thereby realizing the switching of the executing mechanism between the normally closed state and the normally open state.

In this embodiment, as shown in fig. 3 and 9, a first mounting groove 51 is formed on one side of the first dial 50, and one end of the dial rod core 70 is rotatably inserted into the first mounting groove 51. A first connecting groove 52 is formed on a side of the first toggle 50 away from the first mounting groove 51, and the first connecting groove 52 is used for inserting a door handle, so that the door handle can drive the first toggle 50 to rotate relative to the lock housing 10. The groove bottom wall of the first mounting groove 51 and the groove bottom wall of the first connecting groove 52 are through, so that the shift lever can be inserted into the insertion hole 72 of the shift lever core 70 when the lock body 200 is mounted. In addition, a first guide groove 53 is further formed in one side, close to the first mounting groove 51, of the first shifting block 50, the first guide groove 53 extends along the second preset direction B, two ends of the first guide groove 53 penetrate through a side groove wall of the first mounting groove 51 and the outer peripheral wall of the first shifting block 50 respectively, and the first moving member 80 is movably arranged in the first guide groove 53.

Referring to fig. 1 and 10, a second mounting groove 61 is formed in one side of the second toggle element 60, and an end of the toggle core 70, which is far away from the first toggle element 50, is rotatably inserted into the second mounting groove 61. A second connecting groove 62 is formed in one side of the second toggle 60 away from the second mounting groove 61, and the second connecting groove 62 is used for inserting the door handle, so that the door handle can drive the second toggle 60 to rotate relative to the lock case 10. The bottom wall of the second mounting groove 61 and the bottom wall of the second connecting groove 62 are communicated with each other, so that the shift lever can be inserted into the insertion hole 72 of the shift lever core 70 when the lock body 200 is mounted. In addition, a second guide groove 63 is further formed in one side, close to the second mounting groove 61, of the second shifting block 60, the second guide groove 63 extends along the second preset direction B, two ends of the second guide groove 63 penetrate through a side groove wall of the second mounting groove 61 and the outer peripheral wall of the second shifting block 60 respectively, and the second moving member 90 is movably arranged in the second guide groove 63. When the first driver 50 and the second driver 60 are oppositely disposed in the lock case 10, the first guide groove 53 and the second guide groove 63 are oppositely disposed.

Therefore, as shown in fig. 8, the lever core 70 is rotatably disposed in the lock case 10 by the above structure, when the lever core 70 rotates relative to the lock case 10, the avoiding groove 71 disposed on the lever core 70 can be simultaneously aligned with the first guide groove 53 and the second guide groove 63, so that the avoiding groove 71 is simultaneously aligned with the first moving member 80 and the second moving member 90, so that both the first moving member 80 and the second moving member 90 can move into the avoiding groove 71, and the normally open state of the actuator is realized by the lever core 70 with such a structure, so that the lock body 200 cannot be locked.

In addition, the plug hole 72 of the poking rod core 70 can also be used for connecting a mechanical lock core, so that the poking rod core 70 is driven to rotate relative to the lock shell 10 through the mechanical lock core, and therefore the lock body 200 can achieve the electronic and mechanical double unlocking function.

In this embodiment, as shown in fig. 2 and 3, the lock body 200 further includes the blocking member 100. The blocking member 100 is movably disposed within the lock housing 10, the blocking member 100 having a blocking position and a reversing position. When the blocking member 100 is in the blocking position, the blocking member 100 can prevent the locking crown 30 from being switched between the first position and the second position. When the blocking member 100 is in the reversing position, the blocking member 100 can allow the locking crown 30 to be switched between the first position and the second position.

The blocking piece 100 arranged in the lock case 10 can block or allow the locking top piece 30 to be switched between the first position and the second position, so that the locking top piece 30 can be prevented from moving between the first position and the second position after the switching of the positions is completed, and the locking top piece 30 cannot lock the first shifting block 50 or the second shifting block 60 which needs to be locked, and the lock body 200 is unlocked by mistake.

Further, the blocking member 100 is rotatably disposed in the lock case 10, and the blocking member 100 is capable of being switched between a blocking position and a reversing position by rotating relative to the lock case 10, wherein the direction of the rotation axis of the blocking member 100 is the same as the first preset direction a. The structure using the rotation blocking member 100, which allows the blocking member 100 to be switched between the blocking position and the reversing position to prevent or allow the locking crown 30 to move between the first position and the second position, is easy to control and has high stability. In other embodiments, the blocking member 100 may be movably disposed within the housing 10, and movement of the blocking member 100 relative to the housing 10 may be capable of switching between a blocking position and a reversing position.

Illustratively, and as shown in continued reference to FIGS. 2 and 3, the blocking member 100 includes a pivot shaft 101 and a blocking portion 102. The rotary shaft 101 is rotatably disposed in the lock case 10 about an axis thereof, and the rotary shaft 101 extends in a first preset direction a. The blocking portion 102 is connected to the rotating shaft 101 and extends in a radial direction of the rotating shaft 101. The rotation shaft 101 rotates relative to the lock case 10 to drive the blocking portion 102 to abut against the locking top 30 or to be staggered with the locking top 30, so that the locking top 30 is prevented from moving between the first position and the second position or the locking top 30 is allowed to move between the first position and the second position, and the blocking function of the blocking piece 100 is achieved through the structure, and the structure is simple and convenient to achieve.

The blocking portion 102 is an elliptical plate-shaped structure protruding from the rotating shaft 101.

As shown in fig. 3 and 11, when the blocking member 100 is located at the blocking position and the locking top 30 is located at the first position, the blocking portion 102 abuts against one side of the locking top 30 in the first predetermined direction a to prevent the locking top 30 from being switched from the first position to the second position. At this time, the locking head 30 acts on the first toggle 50.

As shown in fig. 12, when the blocking member 100 is located at the blocking position and the locking tip 30 is located at the second position, the blocking portion 102 abuts against the other side of the locking tip 30 in the first preset direction a to prevent the locking tip 30 from being switched from the second position to the first position. At this time, the locking tip 30 acts on the second dial 60.

When the blocking member 100 is in the reversing position (that is, when the rotating shaft 101 is rotated counterclockwise by a certain angle about its axis as shown in fig. 3), the blocking portion 102 is misaligned with the locking tip 30 to allow the locking tip 30 to be switched between the first position and the second position.

Alternatively, as shown in fig. 5 and 11, one end of the rotating shaft 101 of the blocking member 100 close to the first housing 11 penetrates through the first housing 11 and is provided with a straight slot, so that an installer can drive the rotating shaft 101 to rotate relative to the lock case 10 through the straight slot, thereby switching the position of the locking top 30, and the lock body 200 adopting such a structure is convenient to operate and install.

In this embodiment, as shown in fig. 2, 3 and 11, the lock body 200 further includes the pull rod 110. The bolt 20 is fixedly provided with a connecting shaft 21, one end of the pull rod 110 is clamped on the connecting shaft 21, and the other end of the pull rod 110 is connected with the first shifting block 50 and the second shifting block 60, so that the bolt 20 can be driven to move relative to the lock shell 10 when the first shifting block 50 and the second shifting block 60 rotate in the unlocking direction.

As shown in fig. 9 and 10, a first engaging block 54 is protruded from an outer peripheral wall of the first dial 50, and a second engaging block 64 is protruded from an outer peripheral wall of the second dial 60. As shown in fig. 12 and 13, a clamping hole 1101 is formed in the pull rod 110, and the first clamping block 54 of the first toggle mechanism 50 and the second clamping block 64 of the second toggle mechanism 60 are clamped in the clamping hole 1101 of the pull rod 110, so that the pull rod 110 can be driven to move relative to the lock case 10 when the first toggle mechanism 50 and the second toggle mechanism 60 rotate relative to the lock case 10 in the unlocking direction, and the lock tongue 20 is driven to move relative to the lock case 10.

Further, as shown in fig. 2 and fig. 3, the lock body 200 further includes an elastic reset element 120, the elastic reset element 120 is disposed between the lock tongue 20 and the lock case 10, and the elastic reset element 120 is configured to drive the lock tongue 20 to reset after the first toggle 50 or the second toggle 60 drives the lock tongue 20 to move relative to the lock case 10, and drive the first toggle 50 or the second toggle 60 to reset at the same time.

Illustratively, the elastic restoring element 120 is a spring, the spring is sleeved outside the connecting shaft 21 of the bolt 20, and two ends of the spring respectively abut against the bolt 20 and the lock case 10.

Optionally, as shown in fig. 2 and fig. 3, the lock body 200 further includes a protection plate 130, the protection plate 130 is detachably connected to the end surface of the first housing 11 through a bolt, and the protection plate 130 is provided with a hole for the bolt 20 to pass through, so that the protection plate 130 can protect the lock body 200 during use of the lock body 200, and the wear resistance of the lock body 200 is improved.

In summary, the working process of the lock body 200 is as follows: when the lock body 200 is installed in a left-handed door, the first shifting block 50 is close to the outer side of the door and is connected with the door handle on the outer side of the door, the second shifting block 60 is close to the inner side of the door and is connected with the door handle on the inner side of the door, and at the moment, if the execution mechanism is in a normally open state, the two door handles on the inner side and the outer side of the door can both drive the corresponding first shifting block 50 and the corresponding second shifting block 60 to rotate so as to open the door; if the actuating mechanism is in the normally closed state, the door handle of the door inner side can drive the second shifting block 60 to rotate so as to open the door, but the door handle of the door outer side can lock or unlock the first shifting block 50 through the locking top piece 30 so as to enable the locking top piece 30 to allow or prevent the door handle of the door outer side to open the door, therefore, when the door is opened by the personnel of the door outer side by adopting the structure, the personnel of the door inner side only need to rotate the shifting rod core 70 through the shifting rod, so that the actuating mechanism is switched from the normally closed state to the normally open state, and at the moment, the personnel of the door outer side can open the door by rotating the door handle of the door outer side. The specific working principle is as follows: the blocking member 100 is first rotated to the reversing position (as shown in fig. 5) through the linear groove formed on the rotating shaft 101, and then the driving rod is inserted into the reversing hole 13 (as shown in fig. 1) from the second housing 12 to switch the locking head 30 to the first position (as shown in fig. 11), at this time, the locking head 30 cannot act on the second dial 60, and the second dial 60 located inside the door can be rotated in the unlocking direction in any case, so that the second dial 60 can be rotated by the door handle to move the locking tongue 20 relative to the lock case 10 to open the door. Then, the blocking member 100 is rotated to the blocking position, so that the blocking portion 102 of the blocking member 100 abuts against the locking tip 30, thereby preventing the locking tip 30 from being switched from the first position to the second position. At this time, when the escape groove 71 of the lever core 70 is misaligned with the first moving member 80 (as shown in fig. 3), that is, when the actuator is in the normally closed state, after the locking slider 41 is moved from the locking position (shown in fig. 3) to the unlocking position (shown in fig. 6) by the driving member 421 driving the movable block 4222 to move relative to the lock case 10, the locking slider 41 is able to allow the locking head 30 to move in the second preset direction B away from the first dial 50 and the second dial 60, so that the locking top 30 cannot block the first moving member 80 when the first dial 50 is rotated in the unlocking direction, thereby allowing the first shifting block 50 to rotate towards the unlocking direction, so that the first shifting block 50 can drive the bolt 20 to move relative to the lock shell 10 through the pull rod 110, and then realized the function of unblanking of lock body 200 for the door handle in the door outside can drive first shifting block 50 and rotate, in order to open the door. On the contrary, after the driving member 421 drives the movable block 4222 to move relative to the lock case 10 to drive the locking slider 41 to move from the unlocking position (as shown in fig. 6) to the locking position (as shown in fig. 3), the locking slider 41 abuts against the locking top 30 to prevent the locking top 30 from moving in the second preset direction B in a direction away from the first dial 50 and the second dial 60, so that the locking top 30 can block the first moving member 80 when the first dial 50 rotates in the unlocking direction, thereby preventing the first dial 50 from rotating in the unlocking direction, so that the first dial 50 cannot drive the lock tongue 20 to move relative to the lock case 10 through the pull rod 110, further realizing the locking function of the lock body 200, and enabling the door handle outside the door to not drive the first dial 50 to rotate, thereby preventing the door from being opened. When the shift lever core 70 rotates to the avoiding groove 71 and is staggered with the first moving member 80 (as shown in fig. 3), that is, when the actuator is in a normally open state, the shift lever core 70 can allow the first moving member 80 to move in the avoiding groove 71, so that the first moving member 80 can not be blocked by the locking top 30 when the first dial 50 rotates in the unlocking direction, so as to allow the first dial 50 to rotate in the unlocking direction, and further allow the first dial 50 and the second dial 60 to both rotate in the unlocking direction relative to the lock case 10, so that the lock body 200 cannot be locked, and two door handles on two sides of the door can both drive the corresponding first dial 50 and the corresponding second dial 60 to rotate, so as to open the door. Similarly, when the lock body 200 is installed in a right-handed environment, the driving rod is inserted into the reversing hole 13 from the first housing 11 after the blocking member 100 rotates to the reversing position (as shown in fig. 5), and the locking top 30 is switched to the second position (as shown in fig. 12), at this time, the first toggle 50 is close to the inside of the door and connected to the door handle on the inside of the door, and the second toggle 60 is close to the outside of the door and connected to the door handle on the outside of the door, so that the lock body 200 can be applied to different environments.

In addition, the present application further provides a lock, including the lock body 200 described above. The lockset adopting the structure can be suitable for different use environments with a left door or a right door, so that the lockset of various models is not required to be produced aiming at different use environments, the universality of the lockset is greatly improved, and the production cost and the accessory inventory of a production line are reduced.

The lockset can be used for various objects such as file cabinets, doors and windows.

Illustratively, when the lock is used with a left-handed door, the lock further includes an outer handle, an inner handle, and a toggle lever. The lock body 200 is fixedly installed in the installation passage of the door, and a lock groove for inserting the locking bolt 20 is formed on the door frame. The outer handle is engaged with the first connecting slot 52 (see fig. 5) of the first dial 50, and the outer handle is used for driving the first dial 50 to rotate relative to the lock housing 10. The inner handle is engaged with a second connecting slot 62 (see fig. 1) of the second toggle member 60, and the inner handle is used for driving the second toggle member 60 to rotate relative to the lock housing 10. The shift lever is rotatably disposed in the inner handle, and one end of the shift lever is inserted into an insertion hole 72 (shown in fig. 1) of the shift lever core 70, and the shift lever is used to drive the shift lever core 70 to rotate relative to the lock housing 10, so that the avoiding groove 71 of the shift lever core 70 is aligned with or staggered from the first moving member 80 and the second moving member 90. On the contrary, when the lock is used for a door with a right-hand opening door, the locking ejector 30 is switched from the first position to the second position, and the lock body 200 is rotated 180 degrees relative to the door and then installed in the installation channel of the door, at this time, the first shifting block 50 is close to the inner side of the door, the second shifting block 60 is close to the outer side of the door, the inner handle is located on the outer side of the door, and the outer handle is located on the inner side of the door. The inner handle, outer handle, and shifter lever then need to be removed. Then, the inner handle is engaged with the first coupling groove 52 (see fig. 5) of the first dial 50, and the outer handle is engaged with the second coupling groove 62 (see fig. 1) of the second dial 60. Finally, the shift lever is rotatably disposed in the inner handle and one end of the shift lever is inserted into the insertion hole 72 (shown in fig. 1) of the shift lever core 70, so as to complete the switching of the lock for the right-opening environment.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
