Implementation Methods of the Utility Model

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] The present embodiment discloses a reverse-lift locking lock body, as shown in Figures 1-6, comprising a lock body 1, in which a retractable lock tongue 2 is provided. The lock tongue 2 is a magnetic lock tongue. Specifically, a buckle box is provided on the door frame. When the lock tongue faces the buckle box, the lock tongue 2 is adsorbed by the magnet in the buckle box, so that the lock tongue 2 extends out of the lock body 1.

[0023] In this embodiment, a rotatable main dial 3 is provided in the lock body 1, and a rotatable square chip 4 is provided on both sides of the main dial 3. The square chips 4 on both sides are respectively connected to the inner handle and the outer handle on the door. A square hole is provided on the square chip 4, and the inner handle and the outer handle are connected to the square chip 4 through a square shaft; thereby, the square chip 4 on the corresponding side can be driven to rotate by the inner and outer handles; it should be clarified that the square chip 4 has two rotation directions, namely, rotation in the unlocking direction and rotation in the locking direction, corresponding to the handle, when the inner handle or the outer handle is pressed down and rotated, the square chip rotates in the unlocking direction, and when the inner handle or the outer handle is lifted and rotated, the square chip rotates in the locking direction.

[0024] 1, a transmission assembly 5 is provided in the lock body 1, a transmission shift block 402 is provided on the square chip 4, the transmission shift block 402 cooperates with the transmission assembly 5, and the square chip 4 and the lock tongue 2 are linked through the transmission assembly 5; specifically, the transmission assembly 5 includes a sliding rod 501 and a rotating rod 502, and the two ends of the sliding rod 501 are provided with a notch A5011 and a notch B5012, and the lock tongue 2 is provided with a movable groove 201 (the dotted line part on the lock tongue in the figure), one end of the rotating rod 502 is stuck in the notch A5011, and the other end cooperates with the movable groove 201, and the transmission shift block 402 cooperates with the transmission assembly 5. The block 402 is in abutment with the inner wall of the notch B5012, so that when the square chip 4 rotates in the unlocking direction, the lock tongue 2 can be driven by the transmission assembly 5 and then retracted into the lock body 1; wherein, a cavity 11 is provided on the sliding rod 501, and a return spring (not shown in the figure) is stored in the cavity 11, and a fixed block (not shown in the figure) is provided on the outer shell of the lock body 1, which is inserted into the cavity 11 and abuts against the internal return spring. When the sliding rod slides, the return spring is squeezed and contracted by the fixed block and the inner wall of the cavity. After being released, the sliding rod is automatically reset by the return spring.

[0025] 2 , an unlocking dial 301 is provided on the main dial wheel 3, and the unlocking dial 301 cooperates with the locking block 6. When the main dial wheel 3 is rotated in the unlocking direction, the locking block 6 can be driven to move to the unlocking state.

[0026] Furthermore, the main dial wheel can be driven in two ways, corresponding to unlocking the door from the inside and outside. For the first method of unlocking the door from the inside, a linkage member 8 is provided on the main dial wheel 3, protruding toward one side of the square chip 4. The square chip 4 is provided with a linkage portion 9, which engages with the linkage member 8. This allows the main dial wheel 3 to rotate while the square chip 4 unlocks the locking block 6, allowing the lock tongue 2 to retract and open the door. It should be noted that the direction in which the linkage member 8 protrudes depends on the actual opening direction of the door. The linkage member 8 is required on the square chip 4 on the side of the interior door handle to facilitate use inside the door. Preferably, the linkage member 8 can be a screw, which can be quickly screwed onto the main dial wheel 3 during actual installation, effectively simplifying installation. The second type of unlocking the door from outside is that a flat hole 10 is provided on the main dial 3, and a flat strip is passed through the flat hole 10. The flat strip extends to the outside handle on the door, and a rotatable unlocking element is provided on the outside handle. The unlocking element is connected to the flat strip. The unlocking element is preferably a key lock core. After inserting the key outside the door, the flat strip can be driven to rotate by the key, thereby driving the main dial 3 with the flat hole 10 to rotate, so that when necessary, the door can be unlocked by the key from outside.

[0027] Furthermore, the locking block 6 is provided with a spring hole 601, which houses a spring and a steel ball (not shown). The outer shell of the lock body 1 is provided with two retaining holes (not shown), corresponding to the locked and unlocked states of the locking block 6, respectively. The steel balls engage the retaining holes. This simple retaining mechanism primarily ensures that the locking block 6 remains stable after vertical movement, preventing it from falling under gravity and thus maintaining stability in both the locked and unlocked states.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
