The lock shell is assembled on the door cabinet body through the installation base, and the control circuit board is arranged in the lock shell. The rotary switch can stretch and retract relative to the lock body component, so that the rotary switch has stretching and retracting position states relative to the lock shell; the lock body component is arranged at the rear end of the shell and is in transmission fit with the rotating switch. The stop mechanism is arranged in the shell, acts on the rotary switch and has a stop position state and a release position state. And the telescopic driving elastic piece is arranged between the front end of the lock body component and the rear end of the rotating switch, so that the rotating switch always has a movement trend of switching from a retraction position state to an extension position state. When the rotating switch is in the stretching-out position state, torsional force can be transmitted to the lock body component through the elastic piece, and transmission matching of the rotating switch and the lock body component is achieved.

Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a retractable and rotatable electronic lock. Background Technology

[0002] With the development of technology, electronic locks are being used more and more widely in daily life and work. Currently, electronic locks on the market offer various operating methods, but some have shortcomings in terms of ease of operation and coordination between extension and rotation control. The rotating parts of some electronic locks cannot achieve flexible extension and retraction, or the transmission coordination is not stable enough when switching between extension and rotation states, easily leading to problems such as jamming and transmission failure, causing inconvenience to users and failing to meet users' needs for efficient and stable operation of electronic locks.

[0003] A prior art example, referring to patent document CN120007024A, describes a retractable concealed electronic lock, comprising a fixed outer shell having an installation chamber, integrally embedded in a cabinet; a rotating bracket rotatably disposed within the installation chamber; a telescopic shell retractably disposed within the installation chamber, and capable of driving the rotating bracket to rotate; an electronic lock assembly communicatively connected to an electronic lock identification component, and having at least a locked state and an unlocked state; an electronic lock identification component responding to a user's first unlocking operation; a mechanical locking assembly mounted on the rotating bracket; an elastic component acting on the telescopic shell; and a state switching mechanism disposed between the rotating bracket and the telescopic shell, having at least a restricted movement state and a released position state. The lock of this invention achieves a concealed effect, enhances overall aesthetics, and improves security and practicality. The solution provided in the technical example features a telescopic housing and a rotation unlocking function. However, the telescopic and rotation are achieved through two separate mechanisms: first, after the electronic lock is unlocked, the telescopic housing automatically pops out via an elastic component; second, the telescopic housing drives the mechanical locking assembly to unlock via a rotating bracket. This requires a drive block that engages with a rotating groove to transmit torque between the telescopic housing and the rotating bracket (on which the mechanical locking assembly is fixed). Therefore, the structure of the technical example is relatively complex, and the manufacturing difficulty of the components and the assembly process requirements are higher. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings of the prior art, this utility model provides a retractable and rotatable electronic lock. The electronic lock is easy to operate, and the retractable and rotatable movements of the rotary switch are stably coordinated, which can effectively improve the user experience.

[0005] The technical solution of this utility model to solve its technical problem is: a retractable and rotatable electronic lock, comprising:

[0006] The lock housing is assembled onto the cabinet body via a mounting bracket;

[0007] A control circuit board is disposed in the lock housing;

[0008] A rotary switch is capable of telescopic movement relative to the lock body component, such that the rotary switch has at least an extended position and a retracted position relative to the lock housing.

[0009] The lock body component is located at the rear end of the lock housing and forms a transmission engagement with the rotary switch;

[0010] A stop mechanism is provided in the lock housing. The stop mechanism acts on the rotary switch and has at least a stop position state and a release position state relative to the rotary switch.

[0011] A telescopic drive elastic element is provided between the front end of the lock body component and the rear end of the rotary switch. The telescopic drive elastic element acts on the rotary switch so that the rotary switch always has a tendency to switch from the retracted position to the extended position.

[0012] When the rotary switch is in the extended position relative to the lock housing, the transmission section can transmit torsional force to the lock body component through the telescopic drive elastic element, so that the lock body component and the rotary switch form a transmission engagement.

[0013] Through the above-mentioned design, the core features of the electronic lock in this invention are: 1. Coordinated design of telescopic and rotational movement: The transmission section of the rotary switch is simultaneously equipped with a linear guide groove and a rotational groove, which cooperate with the guide ribs on the inner wall of the hole to achieve directional guidance during telescopic movement and flexible rotation during rotational movement. The switching between the two movement states is natural, solving the problem of easy conflict between rotational and telescopic movements in traditional locks. 2. Elastic drive and transmission coordination: The telescopic drive elastic element not only provides the rotary switch with the movement tendency from retraction to extension, but also acts as a medium for transmitting torsional force when the rotary switch is in the extended state, allowing the rotational movement to stably drive the lock body components and avoiding the transmission jamming that is easy to occur with direct rigid connection.

[0014] In some preferred embodiments of this utility model, the rotary switch includes an operating section and a transmission section, the operating section is located at the front end of the transmission section, and the transmission section is movably disposed in the lock housing;

[0015] The lock body component includes a guide section and a bolt section, wherein the bolt section is fixedly installed to the rear end of the guide section;

[0016] The telescopic drive elastic element is installed between the front end of the guide section and the rear end of the transmission section.

[0017] Furthermore, the lock housing has a through hole, and the transmission section is movably inserted through the through hole;

[0018] The inner wall of the through hole is provided with guide ribs, and the transmission section is provided with straight guide grooves distributed along the extension and retraction direction of the rotary switch. The guide ribs are slidably fitted in the straight guide grooves.

[0019] The transmission section is also provided with a rotating groove, which is connected to the end of the straight guide groove. When the rotary switch is in the extended position, the guide rib is located in the rotating groove and can move along the rotating groove.

[0020] Optionally, the outer peripheral wall of the transmission section has a stop;

[0021] When the stop mechanism is in the stop position, the stop mechanism and the stop block form a structural interference to restrict the rotary switch from extending or retracting.

[0022] When the stop mechanism is in the released position, the stop mechanism is offset from the stop block and structural interference is eliminated. The rotary switch can switch between the extended position and the retracted position.

[0023] Optionally, the rear end of the transmission section has a first arc-shaped guide end face, and the front end of the guide section has a second arc-shaped guide end face;

[0024] During the switching process between the retracted and extended positions of the rotary switch, the first arc-shaped guide end face is always at least partially in contact with the second arc-shaped guide end face.

[0025] When the rotary switch is in the extended position, the first arc-shaped guide end face and the second arc-shaped guide end face are offset to allow the rotary switch to rotate.

[0026] In some preferred embodiments of this utility model, the stopping mechanism includes a user information identification component, a driving device, and a stopping execution block;

[0027] The user information recognition component and the driving device are electrically connected to the control circuit board, respectively.

[0028] The user information identification component is configured on the lock housing and used to acquire unlocking signals, and the user information identification component forms a communication connection with the control circuit board;

[0029] The stop actuator has a stop position state and a release position state, and the drive device forms a transmission cooperation with the stop actuator so that the stop actuator can switch between the stop position state and the release position state.

[0030] Furthermore, the stop execution block has a first stop part and a second stop part;

[0031] When the rotary switch is in the retracted position relative to the lock housing and the stop block is in the stopped position, the front end of the stop block abuts against the second stop part to restrict the rotary switch from moving forward.

[0032] More specifically, the stop actuator block also has a third guide portion, and the inner wall of the lock housing is provided with a movable guide groove. The third guide portion is slidably disposed in the movable guide groove so that the stop actuator block moves along the direction of the movable guide groove.

[0033] In some preferred embodiments of this utility model, a linkage component is provided between the driving device and the stop execution block;

[0034] The linkage component includes a transmission spring and a linkage block. The linkage block has an input end and an output end. The input end of the linkage block is connected to the drive device and forms a transmission engagement. The output end of the linkage block forms a transmission engagement with the stop actuator block through the transmission spring.

[0035] Along the movement direction of the stop actuator, an active gap is formed between the output end of the linkage block and the stop actuator, and the front end of the stop actuator has an inclined guide end face;

[0036] When the rotary switch is pressed inward, the transmission section of the rotary switch can abut against the inclined guide end face and form a transmission engagement. Under the action of the rotary switch, the stop actuator block moves closer to the output end of the linkage block along the movable gap, so that the position of the stop actuator block and the transmission section are offset from each other, so that the rotary switch can continue to retract backward.

[0037] Furthermore, the linkage block is provided with a transmission groove, and the drive device has an eccentric output shaft, which is inserted into the transmission groove so that the drive device and the linkage block form a transmission engagement.

[0038] A transverse auxiliary support block is provided on the inner wall of the lock housing, and one side wall of the linkage block abuts against the transverse auxiliary support block;

[0039] The transverse dimension of the transmission groove is larger than the shaft diameter of the eccentric output shaft, so that the eccentric output shaft can be laterally displaced relative to the linkage block in the transmission groove.

[0040] The working mechanism of this utility model is as follows:

[0041] Unlocking Action: The eccentric output shaft of the drive unit moves within the transmission groove, driving the linkage block to move. The linkage block, through a transmission spring, drives the stop actuator block to move, switching the stop actuator block from the stopped position to the released position. At this time, the stop actuator block is misaligned with the stop block on the transmission section, eliminating structural interference. Under the action of the telescopic drive elastic element, the rotary switch switches from the retracted position to the extended position. The user then rotates the operating section of the rotary switch, and the transmission section transmits torsional force to the lock body component through the telescopic drive elastic element, causing the bolt section of the lock body component to move, thus unlocking the lock.

[0042] Locking action: When it is necessary to switch the rotary switch back to the retracted position, the user presses the rotary switch inward. The transmission section abuts against the inclined guide end face of the stop actuator. Under the action of the rotary switch, the stop actuator moves along the movable gap towards the output end of the linkage block. The positions of the stop actuator and the transmission section are offset from each other, and the rotary switch can continue to retract until it returns to the retracted position. At this time, the stop actuator can be returned to the stop position by controlling the drive device to limit the rotary switch.

[0043] The beneficial effects of this utility model are as follows:

[0044] I. Elastic Drive and Transmission Coordination: The telescopic drive elastic element not only provides the rotary switch with the motion tendency from retraction to extension, but also acts as a medium for transmitting torsional force when the rotary switch is in the extended state, so that the rotation action can stably drive the lock body components, avoiding the transmission jamming that is easy to occur in direct rigid connection.

[0045] II. Improved ease of operation: The extension and rotation of the rotary switch are precisely switched through the cooperation of the guide rib, guide groove, and rotation groove. After unlocking, it can automatically extend, and the user can rotate to unlock without additional operation; when retracting, only pressing is required, and the stop block can automatically avoid it. The whole process is smooth and efficient, improving the user experience.

[0046] 3. Enhanced transmission stability: The elastic element of the telescopic drive allows for elastic transmission between the rotary switch and the lock body components, avoiding transmission dead spots and jamming problems under rigid connection; the fitting design of the first and second arc-shaped guide end faces during telescopic switching further ensures the accurate alignment of components during movement, reduces the probability of transmission failure, and makes the lock operation more reliable.

[0047] IV. Safety and Misoperation Prevention Optimization: The dual limit function of the stop mechanism fully restricts the rotation and extension of the rotary switch in the non-unlocked state, effectively preventing accidental opening of the lock due to accidental contact or external impact, thus improving the safety performance of the lock; at the same time, the cooperation between the user information identification component and the control circuit board ensures that only authorized users can initiate the unlocking process, further enhancing security.

[0048] V. Extended Component Lifespan: The buffering effect of the transmission springs in the linkage assembly, the adaptive design of the movement clearance, and the constraint of the motion trajectory by each guide structure reduce hard friction and impact collisions between components. For example, the lateral displacement design of the eccentric output shaft within the transmission groove avoids forced alignment wear between the drive unit and the linkage block, thereby extending the service life of the entire lock.

[0049] VI. Enhanced structural adaptability: The guiding and cooperating structures of each component (such as the third guide part and the movable guide groove of the stop actuator block, the linkage block and the lateral auxiliary support block) make the assembly and movement of the internal components of the lock more tolerant of errors. Even if slight assembly errors occur during long-term use, it can still maintain stable operating performance and adapt to different door cabinet installation scenarios and long-term use needs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0066] Example 1

[0067] Reference Figures 1-12 A retractable and rotatable electronic lock, comprising:

[0068] The lock housing 1, which is mounted to the door cabinet via mounting base 13, provides a carrier for the installation and protection of other components of the entire lock. The control circuit board 5, which is disposed in the lock housing 1, serves as the control core of the lock. A rotary switch 2 is capable of telescopic movement relative to the lock body component 3, such that the rotary switch 2 has at least an extended position state 2a and a retracted position state 2b relative to the lock housing 1; the lock body component 3 is disposed at the rear end of the lock housing 1, and the lock body component 3 and the rotary switch 2 form a transmission engagement; a stop mechanism 4 is disposed in the lock housing 1, the stop mechanism 4 acts on the rotary switch 2, and the stop mechanism 4 has at least a stopped position state 4a and a released position state 4b relative to the rotary switch 2; a telescopic drive elastic element 6 is provided between the front end of the lock body component 3 and the rear end of the rotary switch 2, the telescopic drive elastic element 6 acts on the rotary switch 2, so that the rotary switch 2 always has a tendency to switch from the retracted position state 2b to the extended position state 2a; when the rotary switch 2 is in the extended position state 2a relative to the lock housing 1, the transmission section 22 can transmit torsional force to the lock body component 3 through the telescopic drive elastic element 6, so that the lock body component 3 and the rotary switch 2 form a transmission engagement.

[0069] The key working logic of this embodiment is: the action of rotating the rotary switch 2 can only be transmitted to the lock body component 3 when the rotary switch 2 is in the extended position state 2a; when the rotary switch 2 is in the retracted position state 2b, the rotary switch 2 cannot be rotated, which plays a role in preventing misoperation and improving security.

[0070] The most important advantage of this application, which is different from the existing technology, is that the telescopic drive elastic element 6 not only provides the rotary switch 2 with the motion tendency from retraction to extension, but also acts as the medium for transmitting torsional force when the rotary switch 2 is in the extended state, so that the rotation action can stably drive the lock body component 3, avoiding the transmission jamming that is easy to occur in direct rigid connection.

[0071] Therefore, with the help of the telescopic drive elastic element 6, it can realize the dual functions of telescopic extension and transmission of rotational force, greatly reducing the number of parts, optimizing the internal structure, making the overall structure more compact and reasonable, and improving the stability and reliability during use.

[0072] Example 2

[0073] Based on the structure of Embodiment 1, this embodiment provides a preferred structural scheme for the rotary switch 2, specifically as follows: (Refer to...) Figure 7The rotary switch 2 includes an operating section 21 and a transmission section 22. The operating section 21 is located at the front end of the transmission section 22 and is usually exposed outside the lock housing 1 for user operation. For example, the user can control the state of the lock by rotating or pushing / pulling the operating section 21. The transmission section 22 is movably disposed in the lock housing 1 and plays an important role in transmitting the action of the operating section 21 to subsequent components. Its movement is adapted to the overall operating mechanism of the lock. The lock body component 3 includes a guide section 31 and a latch section 32. The latch section 32 is fixedly installed to the rear end of the guide section 31. The telescopic drive elastic element 6 is installed between the front end of the guide section 31 and the rear end of the transmission section 22. The latch section 32 is a key part for locking the door cabinet. When the latch section 32 rotates, the locking and unlocking actions of the door cabinet can be completed.

[0074] Furthermore, referring to Figure 10 The lock housing 1 is provided with a through hole 16, and the transmission section 22 is movably inserted in the through hole 16. The through hole 16 provides the transmission section 22 with basic movement space and radial constraint.

[0075] Linear telescopic guide structure: Reference Figures 7-8 The inner wall of the through hole 16 is provided with guide ribs 17, and the transmission section 22 is provided with straight guide grooves 223 distributed along the extension and retraction direction of the rotary switch 2. The guide ribs 17 are slidably fitted in the straight guide grooves 223. When the rotary switch 2 performs extension and retraction, the guide ribs 17 slide axially in the straight guide grooves 223, which can effectively limit the rotational freedom of the transmission section 22, ensuring that the rotary switch 2 can only perform extension and retraction along the axial direction without unnecessary rotation, thus ensuring the stability and accuracy of the extension and retraction action.

[0076] Rotational motion release structure: (Refer to) Figures 7-8 The transmission section 22 is also provided with a rotating groove 224, which is connected to the end of the straight guide groove 223. When the rotary switch 2 is in the extended position 2a, the guide rib 17 is located in the rotating groove 224 and can move along the rotating groove 224. Since the rotating groove 224 releases the circumferential constraint on the guide rib 17, the guide rib 17 can move circumferentially along the rotating groove 224, thereby giving the transmission section 22 rotational freedom.

[0077] Optionally, refer to Figures 4-6The outer peripheral wall of the transmission section 22 has a stop 221, which can be offset from or abut against the stop actuator 43. When the stop mechanism 4 is in the stop position 4a, the stop mechanism 4 and the stop 221 form a structural interference to restrict the extension and retraction of the rotary switch 2; when the stop mechanism 4 is in the release position 4b, the stop mechanism 4 and the stop 221 are offset and the structural interference is eliminated, and the rotary switch 2 can switch between the extended position 2a and the retracted position 2b. The setting of the stop 221 makes the cooperation between the rotary switch 2 and the stop actuator 43 clearer, avoiding the problem of unreliable stopping caused by the irregular structure of the rotary switch 2. At the same time, the stop 221 can be designed with a specific shape and size according to the actual force requirements to enhance its structural strength and extend its service life. This cooperative structure further improves the working stability of the stop mechanism 4, echoes the status monitoring of the first position sensor, and jointly ensures the security of the electronic lock in the stop state.

[0078] To further optimize the transmission smoothness between the rotary switch 2 and the lock body component 3, especially the force transmission efficiency during the switching process from telescopic motion to rotary motion, in some preferred embodiments of this utility model: (Refer to...) Figure 7 The rear end of the transmission section 22 has a first arc-shaped guide end face 222, and the front end of the guide section 31 has a second arc-shaped guide end face 33. The curvature radii of the two arc-shaped guide end faces are matched to form a complementary curved surface mating structure.

[0079] The retracted fit: When the rotary switch 2 is in the retracted position 2b, the first arc-shaped guide end face 222 is at least partially always in contact with the second arc-shaped guide end face 33; the advantage is that it ensures the stability of the lock body component 3 in the retracted position and avoids shaking caused by gaps.

[0080] Release mechanism in rotation state: When the rotary switch 2 is in the extended position 2a, the positions of the first arc-shaped guide end face 222 and the second arc-shaped guide end face 33 are offset so that the rotary switch 2 can rotate.

[0081] Example 3

[0082] Based on the structure of Embodiment 1, this embodiment provides a preferred structural scheme for the stop mechanism 4, specifically as follows: (Refer to...) Figures 3-6The stopping mechanism 4 includes a user information identification component 41, a drive device 42, and a stopping execution block 43. The user information identification component 41 and the drive device 42 are electrically connected to the control circuit board 5. It should be noted that the lock housing 1 may have a built-in battery to provide power, or it may be powered by an external power source for the internal electrical components; no special limitation is made here. The user information identification component 41 is configured on the lock housing 1 and is used to acquire unlocking signals, and the user information identification component 41 forms a communication connection with the control circuit board 5. The stopping execution block 43 has a stopping position state 4a and a releasing position state 4b. The drive device 42 and the stopping execution block 43 form a transmission cooperation, so that the stopping execution block 43 can switch between the stopping position state 4a and the releasing position state 4b.

[0083] The control circuit board 5 is the "central brain" of the entire mechanism. On one hand, it is "communicating" with the user information identification component 41 (for example, by transmitting electrical signals through wires or short-range wireless transmission) and receiving the unlocking signal from the user information identification component 41. On the other hand, it will "verify and judge" the signal (for example, comparing whether the collected fingerprint matches the pre-stored fingerprint template and whether the entered password is correct). If the signal is valid, it will send an action command to the drive device 42.

[0084] The stop actuator 43 is the "actuator" that ultimately achieves "stop / release". It has two key states: 1. Stop position state 4a: At this time, it will be stuck on the key transmission path, preventing unlocking (such as restricting the movement of the transmission section 22 of the rotary switch 2), that is, the entire lock is in the locked state; 2. Release position state 4b: At this time, it will exit from the transmission path and no longer obstruct the unlocking action, that is, the entire lock is in the unlockable state.

[0085] In summary, the operating logic of the stop mechanism 4 is as follows: the user information identification component 41 collects the signal → the control circuit board 5 judges the signal → the drive device 42 provides power → the stop execution block 43 moves to unlock.

[0086] The stop mechanism 4 is further configured as follows: Figures 4-6The stop block 43 has a first stop part 431 and a second stop part 432. When the rotary switch 2 is in the retracted position 2b relative to the lock housing 1 and the stop block 43 is in the stopped position 4a, the upper end of the stop block 221 abuts against the first stop part 431 to restrict the rotation of the rotary switch 2, and the front end of the stop block 221 abuts against the second stop part 432 to restrict the forward movement of the rotary switch 2. The core purpose of the first stop part 431 and the second stop part 432 is to provide double protection and enhance the reliability of locking. The first stop part 431 abuts against the upper end of the stop block 221 to counteract the rotational force; the second stop part 432 abuts against the front end of the stop block 221 to counteract the axial force of forward movement. Therefore, the stop is more reliable and can effectively prevent the situation from being bypassed by force or skillful means. The cooperation relationship between the first stop 431 and the second stop 432 and the overall mechanism is as follows: After the user completes the unlock verification through the user information identification component 41, the control circuit board 5 drives the drive device 42 to switch the stop execution block 43 to the release position state 4b. At this time, the first stop 431 separates from the upper end of the stop block 221, and the second stop 432 separates from the front end of the stop block 221 (allowing forward movement). Thus, the double constraint of the rotary switch 2 is released, and the user can complete the unlocking according to normal operation.

[0087] If the stop block 43 moves without guidance, uneven force may cause jamming or misalignment, requiring the drive device 42 (such as a motor or electromagnet) to overcome additional friction or torque, potentially accelerating component wear over time. To address these issues, the stop block 43 also features a third guide portion 433. A movable guide groove 14 is provided on the inner wall of the lock housing 1, and the third guide portion 433 slides within this groove, allowing the stop block 43 to move along the direction of the groove. The cooperation between the third guide portion 433 and the movable guide groove 14 constrains the movement trajectory of the stop block 43, preventing deviation and ensuring the accuracy and stability of the stop block 43 during state switching. Because the movement trajectory is strictly constrained, the first and second stop portions 432 maintain a preset engagement with the stop block 221, achieving the function of "locking when it should lock and releasing when it should release."

[0088] Example 4

[0089] Based on the structure of Embodiment 1, this embodiment provides a transmission structure scheme between the drive device 42 and the stop actuator 43, specifically as follows: (Refer to...) Figure 9A linkage component 7 is provided between the driving device 42 and the stop actuator 43; the linkage component 7 includes a transmission spring 71 and a linkage block 72. The linkage block 72 has an input end 721 and an output end 722. The input end 721 of the linkage block 72 is connected to the driving device 42 and forms a transmission engagement. The output end 722 of the linkage block 72 forms a transmission engagement with the stop actuator 43 through the transmission spring 71. Along the movement direction of the stop actuator 43, the output end 722 of the linkage block 72... A movable gap 73 is formed between the stop actuator 43 and the stop actuator 43, and the front end of the stop actuator 43 has an inclined guide end face 434. When the rotary switch 2 is pressed inward, the transmission section 22 of the rotary switch 2 can abut against the inclined guide end face 434 and form a transmission engagement. Under the action of the rotary switch 2, the stop actuator 43 moves along the movable gap 73 to approach the output end 722 of the linkage block 72, so that the positions of the stop actuator 43 and the transmission section 22 are offset from each other, so that the rotary switch 2 can continue to retract backward.

[0090] The normal unlocking process is as follows: After the control circuit board 5 verifies the unlocking signal, the drive device 42 starts, driving the input end 721 of the linkage block 72 to move → the output end 722 of the linkage block 72 pushes the stop execution block 43 through the transmission spring 71 → the stop execution block 43 moves along the movable guide groove 14, switching from the stop position state 4a to the release position state 4b → the first and second stop parts 432 separate from the stop block 221, and the switch 2 can be rotated to operate normally.

[0091] It is important to emphasize that in the compression-retraction scheme, the linkage mechanism has at least two key points: 1. Movement gap 73: Along the movement direction of the stop actuator 43, a gap is reserved between the output end 722 of the linkage block 72 and the stop actuator 43. The stop actuator 43 moves independently towards the output end 722 of the linkage block 72 (compressing the transmission spring 71, using the movement gap 73 to approach the linkage block 72, realizing the switching of the rotary switch 2 from the extended position state 2a to the retracted position state 2b). 2. Inclined guide end face 434: The inclined structure at the front end of the stop actuator 43 is the force transmission medium for manual operation. When the user presses the rotary switch 2 inward, the transmission section 22 of the rotary switch 2 (the contact part corresponding to the stop actuator 43, preferably the aforementioned stop block 221) abuts against the inclined guide end face 434; then the axial force of the press (inward force) is transformed into a lateral force of the stop actuator 43 along the direction of the movable gap 73 by the guiding effect of the inclined guide end face 434; then, under the action of this force, the stop actuator 43 compresses the transmission spring 71 and approaches the linkage block 72 along the movable gap 73, and finally is offset from the position of the transmission section 22 (stop block 221) of the rotary switch 2 (no longer blocking); at this time, the forward movement constraint of the rotary switch 2 is released, and it can continue to retract backward, and the rotary switch 2 smoothly switches to the retracted position state 2b; finally, under the action of the transmission spring 71, the linkage block 72 resets downward, the stop mechanism 4 switches to the stop position state 4a, and the first stop part 431 and the second stop part 432 resume the limiting and stopping function of the rotary switch 2, so that the rotary switch 2 remains in the retracted position state 2b.

[0092] The mating structure between the linkage block 72 and the drive device 42: Refer to Figure 9 The linkage block 72 is provided with a transmission groove 723, and the drive device 42 has an eccentric output shaft 421. The eccentric output shaft 421 is inserted into the transmission groove 723 so that the drive device 42 and the linkage block 72 form a transmission engagement. The lateral dimension of the transmission groove 723 is larger than the shaft diameter of the eccentric output shaft 421 so that the eccentric output shaft 421 can be laterally displaced relative to the linkage block 72 in the transmission groove 723.

[0093] The working principle is as follows: 1. When the drive device 42 is started, it drives the eccentric output shaft 421 to rotate. The insertion end of the shaft moves along a circular trajectory (both lateral displacement perpendicular to the direction of movement of the linkage block 72 and longitudinal displacement parallel to the direction of movement of the linkage block 72); 2. Because the transmission groove 723 constrains the eccentric shaft, when the eccentric shaft makes circular motion, its longitudinal displacement is transmitted to the linkage block 72 through the groove wall, pushing the linkage block 72 to reciprocate along a preset direction (usually a straight line); 3. The lateral displacement of the eccentric shaft is released through the lateral space dimension of the transmission groove 723 (it will not cause the linkage block 72 to move laterally), ensuring that the linkage block 72 only makes pure linear motion. In summary, the circular motion of the eccentric shaft is successfully converted into the linear motion of the linkage block 72.

[0094] Optionally, refer to Figure 6 A transverse auxiliary support block 15 is provided on the inner wall of the lock housing 1, and one side wall of the linkage block 72 abuts against the transverse auxiliary support block 15. The transverse auxiliary support block 15 counteracts the lateral force exerted on the linkage block 72 by the eccentric shaft, ensuring that the linkage block 72 only performs pure longitudinal movement. By controlling the movement accuracy of the linkage block 72, the stable operation of the entire stop mechanism 4 is indirectly guaranteed.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
