The keyhole and the dial 41 are respectively arranged in the two openings on the front shell 11, so that the keyhole and the dial 41 can be operated from the outside.

[0048] Further referring to Figure 3 , wherein the dial 41 of the dial assembly 40 is hinged to the front shell 11 via a pin 44, and a dial block 411 is provided at one end of the dial 41 located within the receiving space. The end of the dial 41 located outside the receiving space is arranged in a sheet shape for the convenience of user operation. The dial assembly 40 further includes a slider 43 and a guide frame 42, and the guide frame 42 is fixedly connected to the front shell 11. A dial block groove 431 for partially receiving the dial block 411 and being able to be moved up and down by the dial block 411 is provided on one side of the slider 43 facing the dial 41, and a guide groove for partially surrounding the guide frame 42 is provided on the other side of the slider 43 facing away from the dial 41, so that the slider 43 can be driven by the dial block 411 to move along the guide frame 42. An input rack 432 is further provided on the other side of the slider 43 facing away from the dial 41. The input rack 432 is arranged on one side of the opposite side walls for surrounding the guide frame 42. The length direction of the input rack 432 is arranged longitudinally, and the tooth tops of each tooth part face the other side wall. The input rack 432 is used to transmit the displacement of the moving action of the slider 43 to the transmission assembly. In this embodiment, the pin 44 of the dial assembly 40 is arranged transversely, so that the dial 41 can be dialed longitudinally, thereby driving the slider 43 to move up and down longitudinally relative to the guide frame 42. In other embodiments, the setting angle of the pin 44 can be changed according to actual needs, so as to change the dialing angle of the dial 41.

[0049] The transmission assembly includes a clutch assembly 51 that is generally disc-shaped. The clutch assembly 51 is disposed on a side of the guide frame 42 away from the paddle 41. And on a side of the clutch assembly 51 facing the guide frame 42, there is a clutch gear 513 for meshing and driving with the input rack 432. On a side of the clutch assembly 51 away from the guide frame 42, there is a clutch shift block 512. The clutch shift block 512 is disposed on an end face of the side of the clutch assembly 51 away from the guide frame 42 and protrudes axially from this end face. In this embodiment, the clutch assembly 51 further includes a fixing hole 511 that axially penetrates through its central part. The fixing hole 511 is used to rotatably fix the clutch assembly 51 on a positioning pin on the guide frame 42.

[0050] The transmission assembly further includes an unlocking transmission member 52. The unlocking transmission member 52 is generally strip-shaped, and there are two strip-shaped guide holes 522 provided thereon. The strip-shaped guide holes 522 correspond to the guide posts 421 on the guide frame 42, so that the unlocking transmission member 52 can be disposed inside the guide frame 42, with the guide posts 421 inserted into the guide holes 522 to guide the unlocking transmission member 52 to move longitudinally relative to the guide frame 42. At the upper end of the unlocking transmission member 52, there is a guiding portion that protrudes upward in an arc shape. At one end of the lock core assembly 30 facing the inside of the lock, there is an input shift block 53. The input shift block 53 is generally strip-shaped and can be driven by the lock core assembly 30 to rotate. After one end of it rotates to contact the guiding portion of the unlocking transmission member 52, it transmits the thrust to the unlocking transmission member 52 at a certain angle along the contact surface, thereby pushing the guiding portion to move downward. For this reason, the part of the input shift block 53 in contact with the guiding portion is also preferably formed in an arc shape. On a side of the unlocking transmission member 52 facing the clutch assembly 51, there is also a driving rack 521. The driving rack 521 is used to drive the output assembly.

[0051] The output component includes a fixed tongue transmission component 55, an inclined tongue transmission component 54, and a transmission sleeve 56 that are coaxially arranged with the clutch component 51. The fixed tongue transmission component 55 includes a transmission shaft 551, the cross-section of the transmission shaft 551 is square, and one end of the transmission shaft 551 facing the clutch component 51 is provided with a transmission gear 553, and the transmission gear 553 can be engaged with the driving rack 521. A first transmission stop block 552 that protrudes radially outward is further provided on the circumferential side of the transmission gear 553. The inclined tongue transmission component 54 includes a through hole 542 that axially penetrates the inclined tongue transmission component 54, and the transmission shaft 551 can pass through the through hole 542 and is connected to the driving receiving component 90 of the rear part 20. The circumferential outer side of one end of the inclined tongue transmission component 54 facing the rear part 20 includes a transmission part that is set to be square. A second transmission stop block 541 that protrudes axially is provided at one end of the inclined tongue transmission component 54 facing the clutch component 51. The clutch block 512 of the clutch component 51 is circumferentially arranged between the first transmission stop block 552 and the second transmission stop block 541 (see Figure 6a ). The transmission sleeve 56 is generally in the shape of a square sleeve, and the inner side of the transmission sleeve 56 is in shape fit with the transmission part of the inclined tongue transmission component 54, so that the rotation of the inclined tongue transmission component 54 can drive the rotation of the transmission sleeve 56. The other end of the transmission sleeve 56 facing away from the front part 10 is used to be connected to the driving receiving component 90 of the rear part 20.

[0052] Reference Figure 8, the rear part 20 includes a dead tongue assembly 70, an inclined tongue assembly 80, and a drive receiving assembly 90. The drive receiving assembly 90 includes a first receiving portion 92 and a second receiving portion 91. The dead tongue assembly 70 includes a dead tongue 72 and a dead tongue slider 71. The inclined tongue assembly 80 includes an inclined tongue 81, an inclined tongue drive member 82 fixedly connected to the inclined tongue 81, and an inclined tongue drive gear 83. The inclined tongue 81 and the dead tongue 72 can extend or retract respectively through two openings on the side of the rear part 20. The first receiving portion 92 includes a receiving shaft 922 and an output dial 921. The second receiving portion 91 includes a mating receiving portion 912 in the shape of a square column and extending along the axial direction, a through hole axially penetrating the second receiving portion 91, and an output gear 911 provided at one end of the mating receiving portion 912. A receiving hole is further provided at the end of the receiving shaft 922 of the first receiving portion 92 facing the front part 10. The receiving shaft 922 passes through the through hole, such that the receiving hole faces the transmission shaft 551 and is open, and the receiving hole can be in shape fit with the transmission shaft 551. At the same time, the transmission sleeve 56 can be sleeved on the outer edge of the circumferential outer side of the mating receiving portion 912 of the second receiving portion 91 and is in shape fit with it. The first receiving portion 92 and the second receiving portion 91 can rotate relative to each other, so that the rotations of the dead tongue transmission assembly 55 and the inclined tongue transmission assembly 54 can respectively drive the rotations of the first receiving portion 92 and the second receiving portion 91.

[0053] The first receiving portion 92 is used to drive the dead tongue assembly 70. The output dial 921 of the first receiving portion 92 can extend into the groove in the dead tongue slider 71, such that the rotation of the output dial 921 can drive the movement of the dead tongue slider 71, thereby controlling the extension and retraction of the dead tongue 72. Similarly, the second receiving portion 91 is used to drive the inclined tongue assembly 80. The output gear 911 of the second receiving portion 91 meshes with the inclined tongue drive gear 83 of the inclined tongue assembly 80, such that the rotation of the second receiving portion 91 can drive the rotation of the inclined tongue drive gear 83. A drive pin 831 is provided on the side end face of the inclined tongue drive gear. A drive opening 821 is provided on the inclined tongue drive member 82. The drive pin 831 can extend into the drive opening 821. The drive opening 821 has a drive profile. When the inclined tongue drive gear 83 rotates, the drive pin 831 can move along the drive profile and drive the inclined tongue drive member 82 to move back and forth, thereby controlling the extension and retraction of the inclined tongue 81. Preferably, the inclined tongue assembly and / or the dead tongue assembly includes a return mechanism. The return mechanism can, for example, include a spring or torsion spring with one end connected to the inclined tongue assembly and / or the dead tongue assembly and the other end connected to the housing, or an automatic return device driven by a motor, etc.

[0054] Reference Figures 5 to 7d, the operation process of the first embodiment of the present invention will be described below with reference to the accompanying drawings. Figure 6a and Figure 7a shows the initial state of the lock of the first embodiment of the present invention when it is in the anti-lock state. The clutch shifting block 512 is located between the first transmission block 552 and the second transmission block 541, and the first transmission block 552, the second transmission block 541, and the unlocking transmission member 52 are all in their initial positions. Figure 6b and Figure 7b shows the state of the lock of this embodiment when the anti-lock is opened by the key. After the user inserts the key into the lock core assembly 30 and rotates it, the lock core assembly 30 drives the input shifting block 53 to rotate in the A direction to the position shown in the figure. The input shifting block 53 pushes the unlocking transmission member 52 in the B direction, so that the driving rack 521 on the unlocking transmission member 52 drives the transmission gear 553 of the deadbolt transmission assembly 55 to rotate in the C direction, thereby driving the first receiving portion 92 to rotate, and the deadbolt 72 retracts. Figure 6c and Figure 7c shows the state of the lock of this embodiment when the inclined tongue 81 is retracted by driving the paddle 41. After the user toggles the paddle 41 downward, since the paddle 41 is hinged to the front shell 11, the shifting block 411 at the other end of the paddle 41 pushes the slider 43 in the D direction. The input rack 432 on the slider 43 drives the clutch gear 513 on the clutch assembly 51 to rotate in the E direction. The clutch shifting block 512 pushes the second transmission block 541 to rotate in the E direction, thereby driving the inclined tongue transmission assembly 54 to drive the second receiving portion 91 to rotate, and the inclined tongue 81 retracts. Figure 6d and Figure 7d shows the state of the lock of this embodiment when the anti-lock is achieved by driving the paddle 41. After the user toggles the paddle 41 upward, since the paddle 41 is hinged to the front shell 11, the shifting block 411 at the other end of the paddle 41 pushes the slider 43 in the G direction. The input rack 432 on the slider 43 drives the clutch gear 513 on the clutch assembly 51 to rotate in the H direction. The clutch shifting block 512 pushes the first transmission block 552 to rotate in the H direction, thereby driving the first receiving portion 92 to rotate, causing the deadbolt 72 to extend, achieving anti-lock, and at the same time, the transmission gear 553 of the deadbolt transmission assembly 55 also drives the driving rack 521 on the unlocking transmission member 52 to move in the F direction, so that it returns to its initial position.

[0055] In the above-described embodiment, the lock core assembly 30 is used as the unlocking part, and the paddle assembly 40 is used as the driving input part, so that the rotation of the unlocking part is converted into the rotation of the dead bolt transmission assembly 55 along the first direction, and the upward and downward paddle movements of the driving input part are respectively converted into the rotation of the dead bolt transmission assembly 55 along the second direction and the rotation of the inclined bolt transmission assembly 54 along the first direction, thereby respectively realizing the locking and unlocking of the dead bolt of the lock and the extension of the inclined bolt of the lock. In other embodiments not shown, the unlocking part, the drive input part, the transmission assembly, the deadbolt transmission assembly, and the oblique bolt transmission assembly can all be in other forms, for example, the unlocking part and the drive input part can be set as coaxially arranged and relatively rotatable parts, or the deadbolt transmission assembly and the oblique bolt transmission assembly can be separated from each other and arranged in parallel, rather than being set in a coaxial form, or the deadbolt transmission assembly can be sleeved on the radial outer side of the oblique bolt transmission assembly, etc. The clutch assembly and / or the unlocking transmission member can also be set to be coaxial or parallel with the unlocking part and the drive input part, that is, the deadbolt transmission assembly, the oblique bolt transmission assembly and the clutch assembly are arranged in the same direction along their respective axes, and the clutch assembly and the unlocking transmission member can be driven by the unlocking part and the drive input part to rotate in different directions. Alternatively, the clutch assembly and the deadbolt transmission assembly or the oblique bolt transmission assembly can be set to transmit in a gear rack meshing manner. In addition, in addition to using the gear rack meshing method for transmission, a lever-type, bounce-type, or prying-type transmission method can also be used between the clutch assembly and the drive input part, or between the clutch assembly and the dead tongue transmission assembly, or between the clutch assembly and the inclined tongue transmission assembly.

[0056] refer to Figure 9a and Figure 9b, which shows another embodiment of the clutch driving mechanism of the present invention, including a paddle 201, a clutch assembly 202, a fixed tongue transmission assembly 203, and an inclined tongue transmission assembly 204. The paddle 201 is hinged to the lock housing in a manner similar to the above embodiment, and one end thereof facing the inside of the lock extends into the groove of the clutch assembly 202, thereby driving the clutch assembly 202 to move up and down. The clutch assembly 202 includes two racks 206 that are oppositely arranged facing inward and are arranged vertically. The ends of the fixed tongue transmission assembly 203 and the inclined tongue transmission assembly 204 facing the axial direction of the clutch assembly 202 each include a gear 205. The rack 206 can mesh with the gear 205, so that the up-and-down swing of the paddle 201 can be converted into the rotation of the fixed tongue transmission assembly 203 and the inclined tongue transmission assembly 204 through the clutch assembly 202, and then drive the fixed tongue and the inclined tongue to move respectively. The fixed tongue transmission assembly 203 and the inclined tongue transmission assembly 204 each have a transmission shaft, and the axes of their respective transmission shafts are arranged side by side.

[0057] In the above embodiment, there is only one clutch assembly. Understandably, in other embodiments, the clutch assembly can be provided as multiple clutch assemblies arranged coaxially or non-coaxially, as long as it satisfies that the clutch assembly can be driven by the input driving part to drive the fixed tongue transmission assembly and the inclined tongue transmission assembly respectively.

[0058] In a further preferred embodiment, by providing a limiting mechanism that generates abutment between the unlocking part and / or the driving input part in the rotation direction, the unlocking part and the driving input part can rotate independently of each other in the first rotation direction, and in the second direction, the rotation of the unlocking part can drive the driving input part to rotate together, thereby providing the possibility of realizing convenient operation.

[0059] Reference Figures 10a to 10b , in another preferred embodiment, the clutch assembly 302 is arranged at the end of the driving input part 301 on the side facing the fixed tongue transmission assembly 303 and the inclined tongue transmission assembly 304. The fixed tongue transmission assembly 303 and the inclined tongue transmission assembly 304 each include a transmission block 305 that can be driven by the clutch assembly located at the end. After being operated by the user by the driving input part 301, the fixed tongue transmission assembly 303 and the inclined tongue transmission assembly 304 can move respectively along the moving direction driven by the clutch assembly 302. On the premise of meeting the above functions, the clutch assembly can be set in other forms, as long as it satisfies that the clutch assembly is set to be able to be translated or rotated by the input driving assembly, and the fixed tongue transmission assembly and the inclined tongue transmission assembly can be driven by the translation or rotation of the clutch assembly.

[0060] Also refer toFigures 11 to 13 , which shows another preferred embodiment, including a dead tongue transmission assembly 404 and an inclined tongue transmission assembly 405 arranged in parallel, two clutch assemblies 402, a clutch gear set 403, a slider 406 and a paddle 401, and also includes a front housing 410 and a rear housing 420. The dead tongue transmission assembly 404 and the inclined tongue transmission assembly 405 each include a transmission shaft arranged at one end of their own axial direction and a transmission block arranged at the other end opposite to the transmission shaft and protruding in the radial direction, the dead tongue transmission assembly 404 includes a dead tongue transmission block 409, and the inclined tongue transmission assembly 405 includes an inclined tongue transmission block 412. The two clutch assemblies 402 are roughly disc-shaped, with a gear arranged at one end of the axial direction and a clutch block 408 protruding in the axial direction at the circumferential edge at the other end. The two clutch blocks 408 are respectively arranged to abut against the dead tongue transmission block 409 of the dead tongue transmission assembly 404 and the inclined tongue transmission block 412 of the inclined tongue transmission assembly 405 when rotating, thereby driving the dead tongue transmission assembly 404 and the inclined tongue transmission assembly 405 to rotate respectively.
