[0007] The utility model discloses a purpose is realized through the following mode:

[0008] A kind of electronic lock front clutch structure, including square bar, clutch and handle, handle is paired with the one end of clutch and is inserted, and handle can drive clutch to rotate, one end of square bar extends to the lock body of electronic lock, and the other end of square bar extends to clutch, the end portion of square bar extending to clutch is sleeved with clutch rotating block, clutch and clutch rotating block coaxial center are arranged, mounting hole is set up on clutch rotating block, mounting hole is parallel to the axis of clutch rotating block, clutch rotating block is connected with the clutch pin that can move along the axial direction of mounting hole by mounting hole, the moving direction of clutch pin is perpendicular to door, and elastic return element is arranged between clutch pin and clutch rotating block, elastic return element can provide the elastic force that clutch pin is continuously away from clutch and tends to lock body direction, so that clutch pin is subjected to the force that generates disengagement linkage direction, clutch is equipped with linkage pin hole that is coaxially communicated with mounting hole, clutch pin and clutch are horizontally distributed (i.e. perpendicular to door), so that clutch pin can pass through mounting hole and linkage pin hole and be paired.

[0009] When the elastic return element of clutch pin is compressed when applying pushing force to clutch pin, one end of clutch pin passes through mounting hole and is inserted into linkage pin hole, so that handle can drive clutch and clutch rotating block to link and rotate, on the contrary, the pushing force of clutch pin is released, and clutch pin is separated from linkage pin hole under the elastic return of elastic return element, so that clutch and clutch rotating block are separated from linkage.

[0010] Further in the above description, the clutch is formed with a connecting end and a connecting flange, and the handle is provided with a connecting groove paired with the connecting end, so that the handle can drive the clutch to rotate by paired insertion of the connecting end and the connecting groove.

[0011] Paired insertion of the connecting end and the connecting groove enables stable connection of the handle and the clutch, ensures smooth and stable rotation of the handle to drive the clutch, and improves reliability and stability of the clutch structure.

[0012] Further in the above description, the linkage pin hole is arranged on the connecting flange, and the connecting flange is provided with a connecting bolt.

[0013] Arrangement of the linkage pin hole enables smooth insertion of the clutch pin into the clutch to realize linkage, so that when the handle drives the clutch to rotate, the clutch rotating block can be driven by the clutch pin to link and rotate through the connection of the linkage pin hole and the clutch pin, and the square bar is paired with the lock body of the electronic lock, thereby completing the unlocking action and improving the overall stability of the structure.

[0014] Conversely, when the clutch pin is separated from the linkage pin hole, the handle can only drive the clutch to rotate, that is, the locking action is formed.

[0015] Specifically, the central axis of the linkage pin hole extends horizontally with the axis of the connecting groove.

[0016] Further in the above description, the clutch rotating block is formed with a sleeve joint part and a rotating part, the sleeve joint hole for mating and inserting the square rod is formed in the sleeve joint part, and the mounting hole is formed in the rotating part, which extends horizontally along the central axis of the sleeve joint hole.

[0017] Through the sleeve joint hole, one end of the square rod can be mated and inserted into the sleeve joint hole, and the other end of the square rod can be mated and connected with the lock body of the electronic lock, so that the square rod can be linked and rotated in the linkage state, and the square rod is stationary in the separation state, thereby improving the accuracy and stability of transmission.

[0019] The coaxial communication of the mounting hole and the linkage pin hole allows the clutch pin to move smoothly, and compared with the existing technology, the horizontal arrangement of the clutch pin (i.e. perpendicular to the door) avoids potential safety risks caused by the movement of the clutch pin along the activity direction due to the impact.

[0020] At the same time, since the elastic return member can provide a continuous elastic force to the clutch pin away from the clutch, when the electronic lock front panel is knocked, the horizontally distributed clutch pin can avoid the movement of the clutch pin to form a linkage state, and when the electronic lock is knocked, the continuous elastic force of the elastic return member causes the clutch pin to be continuously separated, further improving the stability and reliability of the clutch structure.

[0021] Further in the above description, the clutch pin is formed with a plug-in part and a limiting part, the plug-in part extends coaxially to the mounting hole, and the two ends of the elastic return member are respectively in abutment with the clutch rotating block and the limiting part.

[0022] The design of the clutch pin allows the plug-in part to be stably inserted into the mounting hole, and the elastic return member is in abutment with the clutch rotating block and the limiting part. When the clutch pin is subjected to external force, a return force is generated, avoiding the problem of door lock opening caused by the movement of the clutch pin, and improving the safety and stability of the clutch structure.

[0023] Further in the above description, the elastic return member is composed of a spring.

[0024] Further in the above description, the linkage pin hole is provided with two.

[0025] Specifically, the two linkage pin holes are respectively used for left opening and right opening of the paired electronic lock, i.e. the opening direction of the door.

[0026] The utility model discloses the beneficial effects of: the mounting hole is parallel with the axis of the clutch rotating block, and makes linkage pin hole and mounting hole coaxial communication, when the push force that moves linkage pin hole is added to the clutch pin, the clutch pin adds pressure to the elastic reset piece and makes it produce compression, makes the one end of clutch pin pass through the mounting hole and inserts into linkage pin hole, linkage pin is connected with clutch and clutch rotating block through clutch pin, thereby makes clutch can drive square bar to rotate and form linkage rotation under rotating handle, on the contrary, when the push force that adds to clutch pin is loosened, the elastic reset piece produces reset elastic force, makes it can drive clutch pin and disconnects linkage pin hole, realizes the disengagement of clutch and clutch rotating block.

[0027] Through the setting of the mounting hole parallel to the axis of the clutch rotating block, the axial direction of the mounting hole is perpendicular to the door, and the clutch pin and the clutch are horizontally arranged (i.e. perpendicular to the door), due to the elastic force of the elastic reset piece, the clutch pin continuously receives the disengagement force, when the external force knocks the front panel of the electronic lock up / down or left / right or front, i.e. knocks in the movement direction of the clutch pin, the potential risk of linkage of the clutch and the clutch rotating block is avoided when the clutch pin moves, the stability and reliability of the clutch structure are further improved, and the safety of the clutch structure is enhanced.

DETAILED DESCRIPTION

[0036] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0037] In this embodiment, reference is made to Figures 2-6 The specific implementation of an electronic lock pre-clutch structure includes a square rod 200, a clutch 300, and a handle 100. The handle 100 is paired and inserted with one end of the clutch 300, and the handle 100 can drive the clutch 300 to rotate. One end of the square rod 200 extends to the lock body of the electronic lock, and the other end of the square rod 200 extends to the clutch 300. The end of the square rod 200 extending to the clutch 300 is sleeved with a clutch rotating block 400. The clutch 300 and the clutch rotating block 400 are coaxially arranged. The clutch rotating block 400 is provided with a mounting hole 403 parallel to the axis of the clutch rotating block 400. The clutch rotating block 400 is connected with a clutch pin 500 that can move along the axis of the mounting hole 403 through the mounting hole 403. An elastic reset member 600 is arranged between the clutch pin 500 and the clutch rotating block 400. The elastic reset member 600 can provide a continuous elastic force to the clutch pin 500 away from the clutch 300 and towards the lock body. The clutch 300 is provided with a linkage pin hole 303 coaxially communicated with the mounting hole 403. One end of the clutch pin 500 is used to be distributed vertically to the door, and the one end of the clutch pin 500 can pass through the mounting hole 403 and be paired with the linkage pin hole 303.

[0038] When a pushing force is applied to the clutch pin 500, the elastic reset member 600 is compressed under pressure, one end of the clutch pin 500 passes through the mounting hole 403 and is inserted into the linkage pin hole 303, so that the handle 100 can drive the clutch 300 and the clutch rotating block 400 to rotate in linkage. Conversely, the pushing force on the clutch pin 500 is released, and the clutch pin 500 is separated from the linkage pin hole 303 under the elastic reset of the elastic reset member 600, so that the clutch 300 and the clutch rotating block 400 are separated.

[0039] Further in the above description, the clutch 300 is formed with a connecting end 301 and a connecting flange 302. The handle 100 is provided with a connecting groove paired with the connecting end 301. The clutch 300 is paired and inserted with the connecting end 301 and the connecting groove, so that the handle 100 can drive the clutch 300 to rotate.

[0040] In this embodiment, specifically, the clutch pin 500 is retracted in the direction of the door in the disengaged state, and is pushed out of the door in the engaged state. When an impact force is applied to the front panel of the door lock or the electronic lock, the clutch pin is subjected to a disengaging force, and the impact force applied from the top, bottom, left and right cannot make the clutch pin move in the engaged direction. This structure can solve the potential risks caused by the horizontal clutch pin 500 structure.

[0041] In some embodiments, the engagement pin hole 303 is arranged on the connecting flange 302, and the connecting flange 302 is provided with a connecting bolt for reversing.

[0042] The arrangement of the engagement pin hole 303 allows the clutch pin 500 to be smoothly inserted and engaged with the clutch 300, so that when the handle 100 drives the clutch 300 to rotate, the clutch pin 500 can drive the clutch rotating block 400 to rotate through the connection of the engagement pin hole 303 and the clutch pin 500, and the square rod 200 can be paired with the lock body of the electronic lock, thereby completing the unlocking action and improving the overall stability of the structure.

[0043] Conversely, when the clutch pin 500 is disengaged from the engagement pin hole 303, the handle 100 can only drive the clutch 300 to rotate, i.e. a locking action is formed.

[0044] Specifically, the central axis of the engagement pin hole 303 extends horizontally with the axis of the connecting groove.

[0045] Further in the above description, the clutch rotating block 400 is formed with a sleeving portion 401 and a rotating portion 402. The sleeving hole 404 for pairing and inserting the square rod 200 is formed in the sleeving portion 401, and the mounting hole 403 is formed in the rotating portion 402 and extends horizontally along the central axis of the sleeving hole 404.

[0046] Through the sleeving hole 404, one end of the square rod 200 can be paired and inserted into the sleeving hole 404, and the other end of the square rod 200 can be paired and connected with the lock body of the electronic lock, so that in the engaged state, the square rod 200 can rotate in engagement, and in the disengaged state, the square rod 200 is stationary, improving the accuracy and stability of the transmission.

[0047] Further in the above description, the clutch rotating block 400 is in abutment with the clutch 300, and the mounting hole 403 and the engagement pin hole 303 are coaxially connected.

[0048] The coaxial communication of the mounting hole 403 and the linkage pin hole 303 enables the smooth movement of the clutch pin 500. Compared with the prior art vertical structure (i.e., horizontal to the door), the horizontal arrangement of the clutch pin 500 avoids potential safety risks caused by the movement of the clutch pin 500 due to the impact.

[0049] Meanwhile, since the elastic return member 600 can provide the clutch pin 500 with a continuous elastic force away from the clutch 300, the impact force can be applied in all directions (up, down, left, right, and front) by knocking the electronic lock panel or handle outside the door. When knocking up and down, the clutch pin 500 is prevented from moving up and down to form linkage. When knocking front, the clutch pin 500 is continuously subjected to a force away from the linkage direction due to the elastic force of the elastic return member 600, thereby improving the stability and reliability of the clutch structure.

[0050] Referring to Figures 2-4 The clutch pin 500 is formed with a plug-in part 501 and a limiting part 502, the plug-in part 501 extends coaxially to the mounting hole 403, and the two ends of the elastic return member 600 are respectively in abutment with the clutch rotating block 400 and the limiting part 502.

[0051] The design of the clutch pin 500 enables the plug-in part 501 to be stably inserted into the mounting hole 403 and abut with the clutch rotating block 400 and the limiting part 502 through the elastic return member 600. When subjected to external force, the clutch pin 500 generates a return force, avoiding the problem of door lock opening caused by the movement of the clutch pin 500, and improving the safety and stability of the clutch structure.

[0052] Specifically, as an example, the extension end of the motor drive member abuts with the limiting part 502 of the clutch pin 500. When the motor drive member is extended to apply external force to compress the elastic return member 600, the clutch pin 500 passes through the mounting hole 403 and is inserted into the linkage pin hole 303 through the plug-in part 501, thereby realizing the linkage of the clutch 300 and the clutch rotating block 400.

[0053] Conversely, when the extension end of the motor drive member is retracted, the elastic return member 600 generates a return force through the elastic force, thereby driving the clutch pin 500 away from the clutch 300, so that the plug-in part 501 is separated from the linkage pin hole 303.

[0054] The elastic return member 600 is composed of a spring.

[0055] Specifically, the arrangement of the elastic return member 600 enables the clutch pin 500 to automatically return when not subjected to external force, and drives the clutch pin 500 to separate from the linkage pin hole 303 and the mounting hole 403, thereby ensuring the stability of the clutch structure in the unlocked state.

[0056] The linkage pin hole 303 is provided with two.

[0057] Specifically, the two linkage pin holes 303 are respectively used for left opening and right opening of the paired electronic lock, i.e. the opening direction of the door.

[0058] The linkage pin hole 303 is provided with two.

[0059] The specific use structure in the embodiment is:

[0060] One end of the square rod 200 abuts against the clutch 300 through the clutch rotating block 400, and the other end of the square rod 200 is connected with the lock body. The clutch pin 500 is installed on the clutch rotating block 400 through the elastic reset member 600. The insertion part 501 of the clutch pin 500 is coaxially arranged with the mounting hole 403 and the linkage pin hole 303. The motor driving member is arranged in the electronic lock shell, and the extension end of the motor driving member extends to the limiting part 502 of the clutch pin 500. The clutch 300 and the handle 100 are connected in pairs.

[0061] In the unlocking linkage state, the extension of the motor driving member can apply a pushing force to the limiting part 502 of the clutch pin 500, so that the elastic reset member 600 is compressed under stress, so that the insertion part 501 of the clutch pin 500 passes through the mounting hole 403 and is inserted into the linkage pin hole 303. At this time, rotating the handle 100 can drive the clutch 300 to drive the clutch rotating block 400 to rotate in linkage through the clutch pin 500. The clutch rotating block 400 can control the unlocking of the lock body through the square rod 200.

[0062] In the locking disengagement state, the retraction of the motor driving member cancels the pushing force applied to the limiting part 502 of the clutch pin 500, so that the elastic reset member 600 is reset. The insertion part 501 of the clutch pin 500 is disengaged from the linkage pin hole 303 and the mounting hole 403. At this time, rotating the handle 100 can only drive the clutch 300 to rotate, and the square rod 200 is locked with the lock body.

[0063] The axial extension of the linkage pin hole 303 and the mounting hole 403 to the handle 100 makes the connected clutch pin 500 horizontally flush with the central axis of the clutch 300 (i.e. perpendicular to the door), compared with the vertical arrangement of the clutch pin 500 (i.e. horizontal to the door). In this embodiment, the clutch pin 500 is arranged horizontally, that is, the moving direction of the clutch pin 500 is vertically extended to the door. When knocking the electronic lock up and down, the clutch pin 500 is prevented from moving up and down and forming linkage with the clutch 300, thereby avoiding the potential risk that the handle 100 can be rotated to unlock and affecting the safety of use. At the same time, when knocking the electronic lock from the front, the elastic return member 600 provides the clutch pin 500 with a continuous elastic force to separate from the linkage pin hole 303, so that the front knocking only makes the clutch pin 500 receive the separating force, thereby preventing the clutch pin from moving in the linkage direction, further improving the stability and reliability of the clutch structure, and enhancing the safety of the clutch structure.

[0064] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed in the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the present application, and any simple modification, equivalent change and modification of the above embodiment within the scope of the present application are all within the scope of the present application.
