This design not only improves the durability of the door lock but also extends its service life.

[0045] A decorative cover 110 is located below the faceplate 120. Its relative distance from the handle 100 is adjustable. This adjustable cover allows installers to easily adjust its position to accommodate lock bodies of varying specifications. This design simplifies installation, reduces time and cost, and makes door lock installation more efficient and convenient.

[0046] Several fifth connection holes 135 are provided on the side of the panel 120 that faces the interior of the door. These holes are spaced longitudinally along the panel 120. The lock cylinder decorative cover 110 is provided with a sixth connection hole 140. Fasteners connect the lock cylinder decorative cover 110 and the panel 120 to secure them. The design of these multiple fifth connection holes 135 allows the door lock to accommodate various European-standard lock bodies. Regardless of the specific size of the lock body, users can secure it by selecting the appropriately positioned fifth connection hole 135, thereby improving the door lock's compatibility and applicability.

[0047] The transmission portion 210 is square and prism-shaped. It utilizes standard components, namely, square prism-shaped standard components. This design makes procurement of the transmission portion 210 more convenient and cost-effective. The high interchangeability of standard components allows users to easily find suitable replacements when replacement or repair is required, simplifying the maintenance and replacement process. It is understood that the base of the handle 100 is provided with an inner square shaft sleeve, which facilitates the replacement of different handle styles.

[0048] Reference Figure 8As can be understood, the clutch assembly 130 includes a bearing 230, a transmission rod, a fixing base 150, a linkage block 170, and a washer. The outer ring of the bearing 230 is fixedly mounted on the panel 120, while the inner ring is used to mount the transmission rod, which is inserted into the inner ring of the bearing 230. The transmission rod has a transmission portion 210 at one end and a locking portion 160 at the other end. The fixing base 150 is fixedly mounted to the outer end of the bearing 230 to securely fix the bearing 230 to the panel 120. The linkage block 170 is rotatably mounted at the end of the locking portion 160. The locking portion 160 has a slot 235, which houses the latch 180 and a spring. The linkage block 170 is provided with three notches 240 and a lug 250, which are evenly distributed at 90° intervals along the circumference of the linkage block 170. The locking portion 160 is further provided with a sliding groove 260, which is arranged along the circumference of the locking portion 160. The corresponding central angle of the sliding groove 260 is 180°, and the lug 250 can slide within the sliding groove 260. The washer is annular and is sleeved on the end of the handle 100. The outer ring of the washer abuts the handle 100, and the inner ring abuts the fixing portion.

[0049] The handle 100 is inserted into the transmission portion 210 and is in transmission connection with the locking portion 160. The transmission portion 210 is provided with a first connection hole 220, and the base of the handle 100 is provided with a second connection hole. The first connection hole 220 and the second connection hole are adapted to each other and connected by threaded fasteners to achieve the fixation of the handle 100 and the locking portion 160.

[0050] Reference Figure 2 The lower portion of the panel 120 is provided with a plurality of fifth connection holes 135, spaced apart along the longitudinal direction of the panel 120. The lock cylinder decorative cover 110 is provided with a sixth connection hole 140. Fasteners connect the fifth connection holes 135 and the sixth connection holes 140 to secure the lock cylinder decorative cover 110 and the panel 120. By installing the lock cylinder decorative cover 110 with the fifth connection holes 135 in different positions, the relative distance between the lock cylinder decorative cover 110 and the handle 100 can be quickly adjusted, facilitating installation.

[0051] It is understandable that a bidirectional torsion spring may be provided at the end of the transmission rod, and the bidirectional torsion spring can realize automatic reset of the transmission rod regardless of forward or reverse rotation.

[0052] Reference Figures 1 to 8When installing the door lock, secure the panel 120 to the inside of the door. Then, secure the bearing 230 to the panel 120 via the fixing seat 150. Insert the transmission rod onto the inner ring of the bearing 230. Then, fit the washer over the base of the handle 100, ensuring that the washer abuts against the handle 100 and the inner ring abuts against the fixing portion. Then, insert the handle 100 into the transmission portion 210. Use threaded fasteners to lock the first and second connecting holes to secure the handle 100 to the locking portion 160. Then, rotatably mount the linkage block 170 at the end of the locking portion 160, ensuring that the latch 180 and spring are properly installed in the slot 235. Finally, select the fifth mounting hole at the appropriate location and secure the lock cylinder decorative cover 110 to the panel 120 to adjust the relative distance between the lock cylinder decorative cover 110 and the handle 100.

[0053] When the door lock is in use, when the user turns the handle 100, the transmission part 210 drives the transmission rod to rotate, and then the door lock is opened and closed through the linkage block 170 and the locking part 160. Through the cooperation of the motor 200 and the arc guide rail 190, the latch 180 can automatically insert or withdraw from the notch 240 of the linkage block 170 to achieve the transmission connection or disconnection between the linkage block 170 and the transmission rod. The design of the washer reduces the friction between the handle 100 and the fixed part, improving the smoothness of operation and the service life of the door lock. The adjustable design of the lock core decorative cover 110 enables the door lock to adapt to European standard lock bodies of different specifications, improving the compatibility and aesthetics of the door lock.

[0054] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
