The clutch member 6 has a simple structure, when anti-locking, the inner handle is pulled, that is, when the inner handle drives the upper transfer member 4 to rotate towards the anti-locking direction, the driving part 8 on the upper transfer member 4 promotes the clutch member 6 to switch to the anti-lock position, canceling the circumferential linkage between the lower transfer member 5 and the transfer member 3, at this time, when the outer handle rotates, the lower transfer member 5 idles, and the transfer member 3 cannot drive the lock tongue 2 to retract and unlock; when unlocking, only the inner handle needs to be pressed, that is, when the inner handle drives the upper transfer member 4 to rotate towards the unlocking direction, the upper transfer member 4 drives the transfer member 3 to rotate through the limiting member 7 to unlock, at the same time, the clutch member 6 is switched from the anti-lock position to the unlocking position, and the circumferential linkage between the lower transfer member 5 and the transfer member 3 in the unlocking direction is restored. The clutch switching structure is simpler than the prior art, and has fewer parts, which not only can reduce the assembly difficulty and improve the production efficiency, but also can significantly reduce the production cost, and has stronger market competitiveness.

[0037] As shown in the accompanying drawings Figures 3-6 The clutch member 6 is rotatably arranged on the side of the transfer member 3 through a connecting member 9, when the clutch member 6 is in the unlocking position, the upper transfer member 4 and the lower transfer member 5 are respectively provided with an upper unlocking protrusion 10 and a lower unlocking protrusion 11 for abutting against the end of the clutch member 6, when the upper transfer member 4 rotates, the driving part 8 acts on the inner side of the clutch member 6 to rotate the clutch member 6 from the unlocking position to the anti-lock position. The connecting member 9 can be a pin, two coaxially arranged first through holes are formed on the transfer member 3, a second through hole is formed on the clutch member 6 corresponding to the position between the two first through holes, the pin is in interference fit with the two first through holes and gap fit with the second through hole, and the clutch member 6 can rotate around the pin under the action of external force. When the upper transfer member 4 and the lower transfer member 5 rotate, the transfer member 3 is driven to rotate by pushing the clutch member 6, achieving the effect that the transfer member 3 drives the lock tongue 2 to retract and unlock, and the linkage structure is simple and reliable.

[0038] As attached Figures 3-7 As shown, the clutch 6 has a mounting hole 12 at its end. A positioning spring 13 and a ball bearing 14 are arranged from the inside to the outside of the mounting hole 12. The transfer component 3 has a track surface 15 that mates with the end of the clutch 6. The track surface 15 has a first positioning groove 16 and a second positioning groove 17 for the ball bearing 14 to be partially inserted, meaning the ball bearing 14 is never fully extended from the mounting hole 12. When the clutch 6 is in the unlocked and locked positions, the outer end of the ball bearing 14 engages with the first positioning groove 16 and the second positioning groove 17, respectively. This elastic positioning structure keeps the clutch 6 stably in the unlocked or locked position, preventing changes in its position due to vibration and improving the stability of the lock body structure.

[0039] As attached Figure 2 As shown, the inner side of the lock housing 1 is also provided with a stop protrusion 18. In this embodiment, the stop protrusion 18 and the lock housing 1 are an integral structure. When the clutch 6 is in the deadbolt position, and the upper rotating component 4 drives the middle rotating component 3 and the clutch 6 to rotate in the opposite direction to unlocking, the stop protrusion 18 abuts against the outer side of the clutch 6 to limit it, causing the clutch 6 to rotate from the deadbolt position to the unlock position. When the middle rotating component 3 drives the clutch 6 to rotate and interferes with the stop protrusion 18, the stop protrusion 18 applies a reverse force to the clutch 6, causing the clutch 6 to move to the unlock position, thereby realizing the return of the clutch 6. The linkage structure and operation method of its return are very simple.

[0040] As attached Figure 3 As shown, the limiting component 7 is a limiting screw, threadedly connected to the side of the intermediate component 3 near the upper rotating component 4. The upper rotating component 4 has a limiting protrusion 19 that abuts against the limiting component 7 to form a circumferential linkage when rotating around the unlocking direction. That is, the intermediate component 3 has a screw hole, and the limiting screw is threadedly connected to the screw hole, with the screw head of the limiting screw serving as the limiting structure. The operation of the limiting screw as the limiting component 7, threadedly connected to the upper rotating component 4, is very simple. It can be flexibly disassembled and adjusted according to whether the upper rotating component 4 and the lower rotating component 5 are installed on the inside or outside of the door, greatly improving the convenience of assembly.

[0041] The intermediate component 3 is reset by a torsion spring, that is, one end of the torsion spring abuts against the inner wall of the lock housing 1, and the other end abuts against the intermediate component 3. This is a conventional technical means, so the specific structure will not be described in detail here.

[0042] As attached Figure 8As shown, the transfer member 3 is provided with a first circular groove 20 and a second circular groove 21 on both sides, the upper transfer member 4 and the lower transfer member 5 are respectively provided with a first rotating protrusion 22 and a second rotating protrusion 23 matched with the first circular groove 20 and the second circular groove 21, and the upper transfer member 4 and the lower transfer member 5 are respectively provided with a first square hole 24 and a second square hole 25 matched with the inner handle square rod and the outer handle square rod. The design can realize the rotating installation of the upper transfer member 4 and the lower transfer member 5 on the transfer member 3, and the linkage cooperation of the upper transfer member 4 and the lower transfer member 5 with the square rods on the inner handle and the outer handle.

[0043] More specifically, the upper transfer member 4 and the lower transfer member 5 are respectively matched with the upper and lower inner sides of the lock shell 1, the lock shell 1 is provided with an axle hole on both sides, the side of the axle hole has an arc-shaped extending stroke groove, the upper transfer member 4 and the lower transfer member 5 are respectively provided with a rotating part matched with the axle hole, and the rotating part has a stroke protrusion slidingly arranged in the stroke groove.

[0044] As shown in the accompanying drawings, Figure 2 As shown, the transfer member 3 is provided with an emergency operation hole 26 with a non-circular cross section at the center. When forgetting to take the key, the emergency operation rod hidden on the outer handle can be inserted into the emergency operation hole 26 of the transfer member 3, and the transfer member 3 is rotated to achieve the purpose of emergency unlocking.

[0045] Among them, the upper transfer member 4 and the lower transfer member 5 have the same structure. The universal structure of the upper transfer member 4 and the lower transfer member 5 can reduce the mold opening, reduce the cost, and also make the assembly simpler, which is beneficial to production.

[0046] As shown in the accompanying drawings, Figure 2 As shown, the lock tongue 2 is provided with a follow-up groove 27 at the position inside the lock shell 1, the transfer member 3 is provided with a linkage protrusion 28 matched with the follow-up groove 27, and the linkage protrusion 28 drives the lock tongue 2 to move inward when the transfer member 3 rotates.
