Referring to fig. 1, the preferred embodiment of the present invention is shown.

Door lock push-and-pull transmission structure is including setting up panel 101 on the door body, is connected with handle 102 on panel 101, and handle 102 swings towards panel 101 or deviates from panel 101, and the shape of panel 101 and handle 102 can be diversified, and the user can realize unblanking etc. of door lock through pull handle 102 for panel 101 swing.

The movable pushing plate 103 is arranged in the panel 101, the handle 102 is connected with a linkage part 1022 which swings up and down along with the swinging of the handle 102, the linkage part 1022 penetrates into the panel 101 to be connected with the panel 101, the swinging of the linkage part 1022 synchronously drives the pushing plate 103 to move up and down, in the embodiment, the door lock is of an outward opening type, and when a user pulls the handle 102 outwards, the linkage part 1022 swings upwards and drives the pushing plate 103 to move upwards at the same time.

A rotating shaft 104 which drives the bolt to move through rotation is arranged in the panel 101, the rotating shaft 104 is connected with the pushing plate 103, and when the pushing plate 103 moves up and down, the pushing plate 103 drives the rotating shaft 104 to rotate; the panel 101 is provided with a clutch structure 107, the clutch structure 107 is provided with a driving member driven by a motor to move, and the driving member limits the moving direction of the push plate 103.

In practical application, when the door lock is in an outward opening mode, through inputting correct passwords or fingerprint verification, the motor of the clutch structure 107 rotates to drive the driving piece to move, at the moment, the handle 102 is pulled outwards, the handle 102 drives the linkage piece 1022 to swing upwards, the linkage piece 1022 swings to drive the pushing plate 103 to move upwards, and the pushing plate 103 moves to drive the rotating shaft 104 to rotate, so that the door lock is opened. When the handle 102 is pushed inward, the linkage 1022 swings downward, driving the pushing plate 103 to move downward, so that the rotating shaft 104 rotates reversely, and the back locking of the door lock can be realized.

Of course, when the door lock is in the inward opening state, the limit pin in the clutch structure 107 needs to be adjusted to limit the moving direction of the driving member, so as to limit the rotating direction of the rotating shaft 104 driven by the pushing plate 103, when the door lock is in the inward opening state, the handle 102 is pushed outward to open the door, and when the handle 102 is pulled inward, the door is locked.

The door lock push-and-pull transmission structure provided by the above limits the moving direction of the pushing plate 103 through the driving piece of the clutch structure 107, so that the setting can be performed according to the internal or external arrangement of the door lock, the linkage piece 1022 drives the pushing plate 103 to move through the swinging of the operating handle 102, and further drives the rotating shaft 104 to rotate, the operations of opening or closing the door lock are realized, the structure is simple, and the cost of the door lock is greatly reduced.

The handle 102 has an inner side wall facing the panel 101, and a protrusion 1021 is convexly arranged on the inner side wall of the handle 102, and the protrusion 1021 is hinged with the panel 101, so that the handle 102 can swing relative to the panel 101. The outer end of the linkage 1022 is fixedly connected with the projection 1021, and the inner end of the linkage 1022 penetrates into the panel 101 to form an insertion end for driving the push plate 103 to move up and down. The swinging of the handle 102 swings the insertion end of the link 1022.

The push plate 103 is provided at a lower portion thereof with a receptacle 1036 into which an insertion end of the link 1022 is inserted. In order to buffer the movement of the linkage 1022 with the pushing plate 103, an elastic layer is disposed on an inner sidewall of the socket 1036, and a gap is formed between the insertion end of the linkage 1022 and the elastic layer of the socket 1036.

The panel 101 is provided with a bar groove 1033 for the linkage 1022 to pass through, the bar groove 1033 extends along the height direction of the panel 101, the panel 101 is provided with a torsion spring 106, and the torsion spring 106 drives the linkage 1022 to move in a resetting manner. Therefore, no matter the door lock is arranged internally or externally, when the driving handle 102 swings, the handle 102 is released, the handle 102 is reset, and the linkage 1022, the pushing plate 103 and the rotating shaft 104 are simultaneously driven to reset.

A mounting plate 105 is disposed in the panel 101, a torsion spring 106 is connected to the mounting plate 105, one end of the torsion spring 106 is fixed, and the other end of the torsion spring 106 extends into the bar groove 1033 and abuts against the linkage 1022. Thus, when the linkage 1022 swings, it is deformed against the torsion spring 106, and after the user releases the operation of the handle 102, the linkage 1022 is reset and moved by the restoring force of the torsion spring 106, thereby driving the handle 102, the pushing plate 103 and the rotating shaft 104 to reset in linkage.

Two mounting plates 105 are provided in the panel 101, the two mounting plates 105 are respectively disposed on both sides of the bar groove 1033, and the other ends of the torsion springs 106 on the two mounting plates 105 are disposed up and down to hold the interlocking member 1022. Thus, the other ends of the two torsion springs 106 are held vertically by the link 1022, and the other ends of the torsion springs 106 are deformed in contact with the link 1022 regardless of whether the link 1022 moves downward or upward.

Be equipped with the bar hole in the slurcam 103, the bar hole extends along the direction of height of slurcam 103 and arranges, and the driving piece is worn to establish in the bar hole. In this way, the driving member is moved to the proper position of the strip-shaped hole by the driving of the clutch structure 107, and the moving direction of the push plate 103 can be limited.

The middle of the strip-shaped hole has an upward step 1035 arranged upward and a downward step 1034 arranged downward; the driving member restricts upward movement of the push plate 103 when the driving member abuts against the upward step 1035 from top to bottom, and restricts downward movement of the push plate 103 when the driving member abuts against the downward step 1034 from bottom to top.

The upward step 1035 and the downward step 1034 are respectively and correspondingly arranged on two sides of the strip-shaped hole, and the upward step 1035 and the downward step 1034 are arranged in a vertically staggered manner. In this way, the switching movement of the drive member between the upward facing step 1035 and the downward facing step 1034 is facilitated.

The upper part of the push plate 103 is provided with a sleeve hole 1031, the sleeve hole 1031 extends along the height direction of the push plate 103, and the rotating shaft 104 passes through the sleeve hole 1031; the rotating shaft 104 is provided with an eccentric block in a protruding manner, the middle part of the trepanning 1031 is provided with a lateral notch 1034, and the eccentric block is movably arranged in the lateral notch 1034. Thus, when the pushing plate 103 moves up and down, the rotation of the rotating shaft 104 is driven by the cooperation of the lateral notch 1034 and the eccentric block.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
