In the case of long-term use or under large external forces, the clutch knob of alloy material may be at risk of breaking, thereby affecting the overall performance and safety of the door lock. In addition, the cost of zinc or aluminum alloy is significantly higher than that of steel.

[0004] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

In addition, the design of the anti-lift screw also allows the user to adjust its height as needed, thereby flexibly controlling the activation or cancellation of the anti-lift function. When the anti-lift screw is lowered, it no longer blocks the wing plate. At this time, rotating the handle shaft in the opposite direction will not trigger the locking mechanism, and the anti-lift function is canceled. This adjustable design provides great convenience for users. Users can adjust the state of the anti-lift function at any time according to actual needs, which not only ensures safety but also maintains operational flexibility.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figures 1 to 3 As shown, this embodiment shows an innovative door lock clutch system, which is designed to provide higher safety and operational convenience. The system is mainly composed of a housing 1, a handle shaft 2, a reversing plate 3, a square rod head 4, a clutch plate 5 and an electric clutch structure 6.

[0023] The housing 1 is the supporting structure of the whole system, and its interior is designed to have enough space to accommodate other key components. The handle shaft 2 is installed in the housing 1 through a rotating connection such as a bearing to ensure that it can rotate smoothly. The handle shaft 2 is usually connected to the handle. A commutator 3 is sleeved on the handle shaft 2, and the commutator 3 rotates synchronously with the handle shaft 2 (a circumferential limit structure is provided between the two), and the switch state of the door lock is controlled by its rotation.

[0024] In this embodiment, a square rod head 4 is also provided on the handle shaft 2, and the square rod head 4 is usually connected to the lock core. The square rod head 4 is sleeved on the handle shaft 2 and is rotatably connected to the handle shaft 2. A clutch plate 5 is sleeved on the square rod head 4, and the clutch plate 5 is independent of the square rod head 4, but can rotate synchronously with the square rod head 4.

[0025] In particular, the square rod head 4 and the clutch plate 5 adopt a split design, which significantly simplifies the structure of the entire system. The split design allows the square rod head 4 and the clutch plate 5 (especially the clutch plate 5) to be manufactured using a metal stamping process, such as steel stamping. The steel stamping process can provide higher manufacturing accuracy and material strength, so that the square rod head 4 and the clutch plate 5 have higher structural strength and durability. This high-strength design significantly improves the safety of the lock and reduces the risk of failure due to insufficient material strength. In addition, the split-design square rod head 4 and clutch plate 5 made of steel stamping are easier to manufacture, easier to assemble, and the cost is lower.

[0026] In addition, an electric clutch structure 6 is provided between the clutch plate 5 and the commutator segment 3. The electric clutch structure 6 realizes clutch operation through electric control, thereby improving the convenience and accuracy of operation.

[0027] More specifically, a square hole 51 is provided at the center of the clutch plate 5. The square hole 51 completely matches the shape of the square rod head 4. When the square rod head 4 is inserted into the square hole 51, the two can fit closely together to achieve synchronous rotation. Such a structure is not only simple, but also easy to assemble.

[0028] More specifically, the door lock clutch system of the present invention is designed with an innovative reverse lift function, which is realized through a sophisticated mechanical structure to provide additional security. The core of the reverse lift function is that when the user pulls the handle in the opposite direction, the door lock can automatically lock to prevent the door from being accidentally opened.

[0029] In this embodiment, the left and right sides of the clutch plate 5 are provided with outwardly extending wing plates 52. These wing plates 52 not only enhance the structural stability of the clutch plate 5, but also provide a key mechanical interaction point for realizing the reverse lifting function. A reverse lifting screw 7 is threadedly connected to the commutator segment 3, and the reverse lifting screw 7 is located on one side of the commutator segment 3 and directly corresponds to one side of the wing plate 52.

[0030] When the anti-lift screw 7 is adjusted to an appropriate position, its top can block the corresponding wing plate 52 from above. In this state, when the user rotates the handle shaft 2 in the reverse direction (i.e., counterclockwise when viewed from the side of the handle shaft 2), the commutator plate 3 will rotate synchronously with the handle shaft 2. Since the position of the anti-lift screw 7 has been adjusted to block the wing plate 52, the anti-lift screw 7 on the commutator plate 3 will press the wing plate 52 downward, and this pressure will drive the clutch plate 5 to rotate.

[0031] The rotation of the clutch plate 5 further drives the square rod head 4 to rotate, and the rotation of the square rod head 4 drives the lock core to lock. This series of chain reactions ensures that the door lock can be locked quickly and reliably when the handle is pulled in the reverse direction, thereby enhancing the safety of the door lock.

[0032] In addition, the design of the reverse lifting screw 7 allows the user to adjust its height as needed, thereby flexibly controlling the activation or cancellation of the reverse lifting function. When the reverse lifting screw 7 is lowered, it no longer blocks the wing plate 52, and the reverse rotation of the handle shaft 2 will not trigger the locking mechanism, and the reverse lifting function is cancelled. This adjustable design provides great convenience for the user, and the user can adjust the state of the reverse lifting function at any time according to actual needs, which not only ensures safety but also maintains operational flexibility.

[0033] In summary, the door lock clutch system of the present invention not only enhances the safety of the door lock, but also improves the convenience and flexibility of user operation by introducing a flexible and adjustable anti-lift function.

[0034] More specifically, the handle shaft 2 is sleeved with a torsion spring 8, which not only ensures the automatic reset of the handle after operation, but also provides necessary elastic support for the stable operation of the entire system. The torsion spring 8 is provided with a shift lever 81 on the left and right sides, and the free ends of the left and right wing plates 52 are provided with a first side baffle 521. The housing 1 is provided with a second side baffle 11 at a position corresponding to the first side baffle 521, and the first side baffle 521 and the second side baffle 11 are both located at the lower side of the corresponding shift lever 81. This layout ensures that during the rotation of the clutch plate 5, the shift lever 81 can effectively and elastically press down the first side baffle 521 on one side.

[0035] When the clutch plate 5 rotates, the corresponding lever 81 will exert downward pressure to press the first side baffle 521. This pressure effect enables the first side baffle 521 to automatically reset when there is no external force. This automatic reset mechanism not only improves the convenience of door lock operation, but also ensures that the door lock can maintain good operating performance after multiple uses.

[0036] More specifically, the square rod head 4 and the clutch plate 5 are both metal parts, preferably steel, and preferably made by stamping to obtain better structural strength. This design aims to utilize the high strength and wear resistance of metal to improve the overall performance of the door lock. By using metal materials, the square rod head 4 and the clutch plate 5 can better resist friction and impact in daily use, reducing the risk of wear and damage caused by long-term use. In addition, the high strength of metal parts also means that the door lock is more stable when subjected to external forces and is less prone to failure, thereby improving the safety of the door lock.

[0037] More specifically, the electric clutch structure 6 includes a clutch pin 61 slidably connected to the side of the clutch plate 5 and capable of sliding up and down, a socket 31 provided on the side of the commutator plate 3 and capable of allowing the clutch pin 61 to be inserted from bottom to top, an electric drive assembly 62 provided below the clutch plate 5 and used to push the clutch pin 61 upward, and an elastic reset member 63 (preferably a spring) provided between the clutch pin 61 and the clutch plate 5 and elastically pressing the clutch pin 61 downward.

[0038] When the clutch pin 61 is aligned with the corresponding socket 31 and inserted therein, the commutator segment 3 and the clutch plate 5 are engaged together and rotate synchronously; when the clutch pin 61 is disengaged from the socket 31, the commutator segment 3 and the clutch plate 5 are separated.

[0039] It is worth noting that the side of the commutator segment 3 has two sockets 31, and the two sockets 31 are arranged symmetrically. When the clutch pin 61 is inserted into the two sockets 31, it corresponds to the locked state and the unlocked state respectively.

[0040] More specifically, the electric drive assembly 62 includes an arc-shaped top pressure plate 621, which is designed to be arc-shaped to better adapt to the moving trajectory of the clutch pin 61 and provide uniform thrust. The drive motor 622 provides power, and the transmission structure 623 is located between the top pressure plate 621 and the drive motor 622, responsible for converting the rotational motion of the motor into the linear motion of the top pressure plate 621, thereby accurately controlling the up and down movement of the clutch pin 61. The transmission structure 623 is usually a gear set.
