Technical Field

[0001] The invention patent relates to the technical field of door locks, specifically, to the push-pull transmission structure of door locks. Background Art

[0002] A door lock is a device used to lock a door to prevent others from opening it. There are many types of door locks, and different occasions have different requirements for door locks. Ordinary families generally use anti-theft door locks, which are highly secure and relatively inexpensive.

[0003] In existing technology, door locks often have a password. The user enters the password and swings the handle on the operation panel to control the door lock to open. During the operation of the handle, the user drives the lock tongue open through the push-pull transmission structure, thereby opening the door. The push-pull transmission structure of existing door locks is relatively complex, resulting in a complex structure and high cost of the entire door lock. Summary of the Invention

[0020] Reference Figure 1 The figure shows a preferred embodiment of the present invention.

[0021] The door lock push-pull transmission structure includes a panel 101 arranged on the door body, and a handle 102 is connected to the panel 101. The handle 102 swings toward or away from the panel 101. The shapes of the panel 101 and the handle 102 can be diverse. The user can unlock the door lock by pulling the handle 102 to swing relative to the panel 101.

[0022] A movable push plate 103 is provided inside the panel 101, and the handle 102 is connected to a linkage part 1022 that swings up and down with the swing of the handle 102. The linkage part 1022 passes through the inside of the panel 101 and is connected to the panel 101. The swing of the linkage part 1022 synchronously drives the push plate 103 to move up and down. In this embodiment, the door lock is an outward-opening type. When the user pulls the handle 102 outward, the linkage part 1022 swings upward, and at the same time drives the push plate 103 to move upward.

[0023] A rotating shaft 104 is provided in the panel 101, which drives the lock tongue to move by rotation. The rotating shaft 104 is connected to the push plate 103. When the push plate 103 moves up and down, the push plate 103 drives the rotating shaft 104 to rotate; a clutch structure 107 is provided in the panel 101, and the clutch structure 107 has a driving member driven by a motor to limit the moving direction of the push plate 103.

[0024] In actual use, when the door lock is in the outward opening mode, by entering the correct password or fingerprint verification, the motor of the clutch structure 107 rotates and drives the driving member to move. At this time, the handle 102 is pulled outward, and the handle 102 drives the linkage member 1022 to swing upward. The swinging of the linkage member 1022 drives the push plate 103 to move upward. The movement of the push plate 103 drives the rotation shaft 104 to rotate, thereby achieving the effect of unlocking the door lock. When the handle 102 is pushed inward, the linkage member 1022 swings downward, driving the push plate 103 to move downward, thereby reversing the rotation shaft 104 and achieving the effect of locking the door lock.

[0025] Of course, when the door lock is opened inward, it is necessary to adjust the limit pin in the clutch structure 107 to limit the moving direction of the driving member, thereby limiting the rotation direction of the push plate 103 to drive the rotating shaft 104. When the door lock is opened inward, pushing the handle 102 outward opens the door, and pulling the handle 102 inward locks the door.

[0026] The door lock push-pull transmission structure provided above limits the moving direction of the push plate 103 through the driving member of the clutch structure 107, so that it can be set according to whether the door lock is built-in or external. By swinging the operating handle 102, the linkage member 1022 drives the push plate 103 to move, and then drives the rotating shaft 104 to rotate, thereby realizing operations such as opening or closing the door lock. The structure is simple and greatly reduces the cost of the door lock.

[0027] The handle 102 has an inner sidewall facing the panel 101. A protrusion 1021 is protruded from the inner sidewall of the handle 102. The protrusion 1021 is hingedly connected to the panel 101, allowing the handle 102 to swing relative to the panel 101. The outer end of a linkage member 1022 is fixedly connected to the protrusion 1021, while the inner end of the linkage member 1022 extends into the panel 101, forming an insertion end that drives the push plate 103 to move up and down. As the handle 102 swings, the insertion end of the linkage member 1022 also swings accordingly.

[0028] The lower part of the push plate 103 is provided with a socket 1036, and the insertion end of the linkage member 1022 is inserted into the socket 1036. In order to cushion the movement of the push plate 103 driven by the linkage member 1022, the inner side wall of the socket 1036 is provided with an elastic layer, and there is a gap between the insertion end of the linkage member 1022 and the elastic layer of the socket 1036.

[0029] The push plate 103 is provided with a slot 1033 for the linkage member 1022 to pass through. The slot 1033 extends along the height of the panel 101. A torsion spring 106 is provided within the panel 101 to drive the linkage member 1022 to reset. Thus, regardless of whether the door lock is internal or external, when the driving handle 102 is swung and released, the handle 102 resets, simultaneously driving the linkage member 1022, the push plate 103, and the rotating shaft 104 to reset.

[0030] A mounting plate 105 is provided within the panel 101, to which a torsion spring 106 is connected. One end of the torsion spring 106 is fixed, while the other end extends into the slot 1033, abutting against the linkage member 1022. Thus, when the linkage member 1022 swings, it abuts against the torsion spring 106 and deforms. When the user releases the handle 102, the restoring force of the torsion spring 106 causes the linkage member 1022 to return to its original position, thereby causing the handle 102, the push plate 103, and the rotating shaft 104 to return to their original position.

[0031] Two mounting plates 105 are provided within the panel 101. The two mounting plates 105 are respectively arranged on either side of the slot 1033. The other ends of the torsion springs 106 on the two mounting plates 105 are arranged vertically to clamp the linkage member 1022. In this way, the other ends of the two torsion springs 106 respectively clamp the linkage member 1022 vertically. Regardless of whether the linkage member 1022 moves downward or upward, it will abut against the other ends of the torsion springs 106 and deform.

[0032] The push plate 103 is provided with a strip hole extending along the height direction of the push plate 103, and the driving member is inserted into the strip hole. In this way, the driving member is moved to the appropriate position of the strip hole by the clutch structure 107, thereby limiting the movement direction of the push plate 103.

[0033] The middle part of the strip hole has an upward step 1035 and a downward step 1034; when the driving member abuts against the upward step 1035 from top to bottom, the driving member limits the push plate 103 from moving upward, and when the driving member abuts against the downward step 1034 from bottom to top, the driving member limits the push plate 103 from moving downward.

[0034] The upward step 1035 and the downward step 1034 are respectively arranged on both sides of the strip hole, and the upward step 1035 and the downward step 1034 are arranged in an up-down staggered manner. In this way, it is convenient for the driving member to switch and move between the upward step 1035 and the downward step 1034.

[0035] The upper portion of the push plate 103 is provided with a sleeve hole 1031, which extends along the height of the push plate 103. The rotating shaft 104 passes through the sleeve hole 1031. The rotating shaft 104 is provided with an eccentric block protruding from the rotating shaft 104. The middle portion of the sleeve hole 1031 is provided with a lateral notch 1032, and the eccentric block is movably positioned in the lateral notch 1032. In this way, when the push plate 103 moves up and down, the cooperation between the lateral notch 1032 and the eccentric block will drive the rotation of the rotating shaft 104.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
