An embodiment of the present application provides a push-pull lock 100, where the push-pull lock 100 includes: outdoor side cover plate 110, latch core structure 120, positioning member 130, and fastener 140.

The outdoor side cover plate 110 is disposed at an outdoor side of the door and connected to the door, and the outdoor side cover plate 110 is provided with a groove 101. One end of the lock cylinder structure 120 is fitted into the recess 101 and abuts against the bottom wall of the recess 101, and the bottom wall of the recess 101 is used to face the room. The positioning member 130 has a first surface (not shown) facing the bottom wall of the recess 101, the first surface abutting the plug structure 120. And a fastener 140, by which the positioning member 130 is detachably fixed to the outdoor side cover plate 110.

The push-pull lock 100 further includes an indoor side cover 210 and a key 220 when installed on a door. The indoor cover 210 is provided on the indoor side of the door and connected to the door, the outdoor cover 110 is located on the outdoor side of the door and connected to the door, the indoor cover 210 is provided opposite to the outdoor cover 110, and the indoor cover 210 is connected to the outdoor cover 110, so that the push-pull lock 100 can be mounted on the door.

Because the groove 101 is formed in the outdoor side cover plate 110, one end of the lock cylinder structure 120 is matched with the groove 101, so that the lock cylinder structure 120 can be prevented from shaking in the using process. Because the bottom wall of the groove 101 faces the indoor space and one end of the lock cylinder structure 120 abuts against the bottom wall of the groove 101, the bottom wall of the groove 101 can block the lock cylinder structure 120 from moving towards the outdoor direction; the first surface faces the bottom wall of the groove 101, namely faces outdoors, and abuts against the lock cylinder structure 120, so that the first surface can prevent the lock cylinder structure 120 from moving indoors, namely the bottom wall of the groove 101 can prevent the lock cylinder structure 120 from moving outdoors, and the first surface can prevent the lock cylinder structure 120 from moving indoors, so that the bottom wall of the groove 101 and the first surface can position the lock cylinder structure 120, and further the lock cylinder structure 120 can be prevented from moving in the using process. Since the positioning member 130 is detachably fixed to the outdoor side cover plate 110 by the fastening member 140, the latch core structure 120 is reliably fixed between the bottom wall of the recess 101 and the first surface, and the latch core structure 120 is prevented from shaking. When the lock core structure 120 is damaged due to long-time use of internal parts, only the outdoor side cover plate 110 needs to be detached from the door, the fastener 140 is taken down, the positioning piece 130 is separated from the lock core structure 120, after the positioning piece 130 is detached, the first surface is relieved to limit the lock core structure 120, the lock core structure 120 can move towards the indoor side cover plate 210, the lock core structure 120 is taken out of the groove 101, the lock core structure 120 can be replaced by a new one, the replacement is simple and convenient, and the lock core structure can be operated without a professional.

Referring to fig. 3, in an embodiment, the outdoor side cover plate 110 and the indoor side cover plate 210 are connected to the door by bolts, so that the push-pull lock 100 is fixed to the door.

Referring to fig. 1 and fig. 2, in an embodiment, the lock core structure 120 is provided with a positioning slot 102, the positioning member 130 has a first positioning protrusion 131, the first positioning protrusion 131 is matched with the positioning slot 102, the first surface is a surface of the first positioning protrusion 131, and the first surface abuts against a slot wall of the positioning slot 102.

Specifically, since the first positioning protrusion 131 has a smaller volume than the positioning element 130 and is more adapted to the positioning slot 102, the first positioning protrusion 131 is more conveniently matched with the positioning slot 102, and the matching is more reliable. When the lock core structure 120 needs to be replaced, the first surface is separated from the groove wall of the positioning groove 102, a new lock core structure 120 is replaced, and the bottom wall of the positioning groove 102, which is formed by the new lock core structure 120, is abutted to the first surface.

In other embodiments, the positioning groove may be formed in the positioning member, the lock cylinder structure has a first positioning protrusion, the first positioning protrusion is matched with the positioning groove, the first surface is a groove wall of the positioning groove, and the first surface abuts against the first positioning protrusion.

Referring to fig. 1 and fig. 2, in an embodiment, the positioning member 130 has a second positioning protrusion 132, and the second positioning protrusion 132 is detachably fixed to the outdoor side cover plate 110 by a fastener 140.

Specifically, since the positioning member 130 further has the second positioning protrusion 132, the second positioning protrusion 132 has a smaller volume than the positioning member 130, so that the connection is more convenient when the second positioning protrusion 132 is engaged with the fastening member 140. The second positioning protrusion 132 is fixed to the outdoor side cover plate 110 by the fastener 140, and the positioning member 130 is fixed to the outdoor side cover plate 110 by the fastener 140. And the first surface of the positioning member 130 abuts against the bottom wall of the positioning slot 102, so that the plug assembly 120 is fixed with the outdoor side cover plate 110 indirectly through the fastener 140. When the key cylinder structure 120 needs to be replaced, the second positioning protrusion 132 is separated from the outdoor side cover plate 110 by the fastener 140, and the first surface is separated from the bottom wall of the positioning groove 102, and then a new key cylinder structure 120 is replaced.
