Referring to fig. 1 to 3, in the lock of the embodiment, a positioning assembly is further included, the positioning assembly is at least partially fixed with the first component to be locked, one of the positioning assembly or the reversing transmission member 32 includes a positioning portion 43 capable of elastic deformation, and the other includes a limiting portion 326 disposed corresponding to the positioning portion 43. In this embodiment, the positioning portion 43 is a positioning elastic member, the positioning portion 43 is fixedly disposed on the mounting seat 41 by a positioning fixing plate 42, the defining portion 326 is disposed on the reversing transmission member 32, a plurality of grooves are circumferentially spaced on an outer peripheral side surface of an end of the positioning portion facing the first side, the positioning portion 43 includes a protrusion corresponding to the grooves, and the positioning portion 43 can elastically deform so as to form an elastically releasable fit with the grooves when the reversing transmission member 32 rotates.

Referring to fig. 7a and 8b, in this embodiment, the reversing drive member 32 has two setting states, a first setting state and a second setting state in which the reversing drive member 32 is mounted by rotating 180 ° about the mounting direction a from the first setting state. In the first setting state, as shown in fig. 7a and 7B, the first transmission member 124 is adjacent to the second transmission member 322 in the first rotation direction B when not driven, and when the first transmission member 124 rotates in the first rotation direction B, the second transmission member 322 can be driven to the locking position in the first rotation direction B. In the second installation state, as shown in fig. 8a, the first transmission member 124 is adjacent to the second transmission member 322 in a second rotation direction C opposite to the first rotation direction B when not driven, and the second transmission member 322 can be driven in the second rotation direction C when the first transmission member 124 rotates in the second rotation direction C. From this, through the transform the state that sets up of switching-over driving medium 32 makes locking piece 45 borrows by switching-over driving medium 32 can be rotatory towards first direction of rotation B or second direction of rotation C respectively, and this makes no matter treat that the first part of locking is rotatory left and opens or the right rotation opens, the utility model discloses a tool to lock all can need not to change the part and can install on it and normally work. Here, the locking member 45 may be formed to have two setting states, for example, as shown in fig. 7a to 8b, the locking member 45 is formed in a sheet shape, and can be attached to the reversing drive member 32 after both side surfaces thereof are turned over while the direction of the connecting portion thereof is turned over. It will be appreciated that the locking member 45 may be provided in other shapes, or have a longer length, etc., as long as it is capable of forming a lock with the second member.

In particular, in the step of locking using the lock according to the above embodiment. When the lock is mounted to a first component and in an unactuated state, the locking element 45 is in a first position separated from the second component, with its connection not coupled to the second component. When the knob 11 is driven by an external driving force without inserting a key to rotate in a first direction for locking, the knob driver 12 receives a torque transmitted from the knob 11 to rotate in the first direction. One leg of the limiting torsion spring 13 is pushed in the first direction by the spring retaining portion 126 of the knob transmission member 12, and the other leg of the limiting torsion spring 13 abuts against the reset retaining portion 462 of the housing 46 in the first direction on the other side of the reset retaining portion 462, so that the limiting torsion spring 13 provides a spring force acting in a second direction opposite to the first direction for returning to the knob 11 in the process that the knob 11 rotates in the first direction. Meanwhile, the first transmission member 124 of the knob transmission member 12 abuts against and pushes the second transmission member 322 of the reversing transmission member 32 along the first direction, so that the reversing transmission member 32 rotates along the first direction until the limiting portion 326 on the outer peripheral side surface of the reversing transmission member 32 and the positioning portion 43 are elastically matched, even if the protruding portion of the positioning portion 43 enters the groove on the outer peripheral surface of the reversing transmission member 32. The rotation of the reversing transmission member 32 drives the locking member 45 connected thereto to rotate, and then moves to a second position coupled to the second member to complete locking and locking. At this time, if the knob assembly 10 is further rotated in the first direction, the leg of the limiting torsion spring 13 pushed by the spring holding portion 126 in the first direction will push against the rotation limiting portion 464 in the first direction, so that the knob assembly 10 cannot rotate continuously in the first direction.

In the locking process, the lock tube 19 rotates together with the knob assembly 10, and the cylinder 34 is rotated in a first direction while being driven by the lock tube 19. Due to the clutch connection between the lock cylinder 34 and the lock ruler 31, the lock ruler 31 is driven by the lock cylinder 34 to rotate along the first direction when the lock cylinder rotates along the first direction. Because the locking rule 31 is in clearance fit with the locking rule interface 324 of the reversing transmission member 32, and the reversing transmission member 32 is driven by the knob transmission member 12 to rotate in the first direction, the torque on the locking rule 31 is not transmitted to the reversing transmission member 32 through the locking rule interface 324.

After the locking step is completed, the external driving force to the knob 11 can be released, and at this time, the knob assembly 10 automatically rotates and returns to the original position along the second direction under the elastic force of the limiting torsion spring 13. The reversing transmission member 32 is not moved due to the engagement between the defining portion 326 on the outer peripheral side surface of the reversing transmission member 32 and the positioning portion 43. Meanwhile, due to the clutch type transmission connection between the lock ruler 31 and the lock cylinder 34, when the lock cylinder 34 rotates along the second direction and does not exceed the clutch angle range, the lock ruler 31 can keep the position thereof and does not move along with the rotation of the lock cylinder 34 along the second direction. At this time, since the reversing driver 32 is already positioned at the locking position, even if the knob assembly 10 is rotated in the first direction or the second direction, the knob assembly 10 cannot drive the reversing driver 32 to be out of the locking position due to the two rotation limiting portions 464 limiting the rotation assembly 10. In the present embodiment, the clutch angular range described herein is set such that the knob assembly 10 can be rotated within an angular range defined between the two rotation restricting portions 464.

In the step of unlocking by inserting the key, the cylinder core 34 and the lock tube 19 are freely rotatable relative to each other by the insertion of the key, and the cylinder core 34 is rotatable in the second direction by the driving of the key, and drives the lock ruler 31 to rotate in the second direction. The locking rule 31 further drives the reversing drive member 32 to rotate in the second direction by its engagement with the locking rule interface 324 of the reversing drive member 32. The reversing transmission member 32 is disengaged from the positioning spring member by the driving force of the key, and further drives the locking member 45 to rotate in the second direction, thereby completing unlocking.

It should be understood that the lock ruler 31 and the reversing driver 32 may be locked by inserting a key into the cylinder 34 and rotating the key in the first direction.

Referring to fig. 9, in an alternative embodiment, the locking assembly of the lock 100 according to the above embodiment may further include a lock body 50, and the lock body 50 may be driven by the locking member 45, for example, or in other embodiments, the locking member may be formed in other forms, such as a rod-shaped locking member 47 as shown in fig. 9, and one end of the locking member is fixedly connected to the reversing driver 32, and the other end of the locking member is connected to the driving connection portion 54 of the lock body. The lock 100 is disposed on a first member 70, and drives the latch 301 of the lock 50 to move for locking. In this embodiment, the latch tongue 301 is a dead tongue, or dead bolt, that is, the latch tongue 301 does not include an inclined surface for a latch tongue structure, and when a lock with a dead tongue is locked or unlocked, a control component of the lock must be operated to control the extension or retraction of the dead tongue. In contrast, in the case of using the latch tongue structure, it is generally only necessary to make an object touch and push the inclined surface of the latch tongue perpendicularly to the extending direction of the latch tongue, so as to push the latch tongue to retract. Therefore, compared with the oblique tongue structure, the dead tongue structure has higher safety.
