Referring to fig. 1 and 2, an embodiment of the present invention provides a push-pull lock, which includes a lock housing 100, a lock body 200, and a positioning assembly 300.

The lock case 100 is provided with a stopper 120. The lock body 200 is provided to the lock case 100, and the lock body 200 has a locking position and an unlocking position in the first direction OX. The positioning assembly 300 is connected with the lock body 200, the positioning assembly 300 includes an elastic member 310 and a matching portion 320, at least one end of the elastic member 310 along the second direction OY is provided with the matching portion 320, the matching portion 320 is arranged corresponding to the stopper portion 120, and the matching portion 320 can be switched between the extended position and the retracted position through elastic deformation of the elastic member 310 along the second direction OY; when the lock body 200 is at the unlocking position and the locking position, respectively, the positioning assemblies 300 are located at two different sides of the stopping portion 120 along the first direction OX, respectively, and the engaging portion 320 is at the extending position, so that the stopping portion 120 blocks the engaging portion 320 from switching between the two different sides of the first direction OX; when the engaging portion 320 is switched to the retracted position, the blocking by the stopper portion 120 can be released.

In the present embodiment, the stopper 120 is used to cooperate with the cooperating portion 320 of the positioning assembly 300 by providing the stopper 120 on the lock case 100. When the lock body 200 is located at the unlocking position, the positioning assembly 300 is located at one side of the stopping portion 120, the elastic member 310 drives the matching portion 320 to extend out to one side of the stopping portion 120, that is, the matching portion 320 is located at the extending position, and at this time, the matching portion 320 and the stopping portion 120 form a limit position along the first direction OX, so that the lock body 200 can be stably located at the unlocking position.

When the lock body 200 is switched from the unlocking position to the locking position, the lock body 200 drives the positioning assembly 300 to move in the lock case 100 along the first direction OX, so that the stopping portion 120 presses the engaging portion 320 along the second direction, and the engaging portion 320 is in the retracted position under the elastic deformation of the elastic member 310.

When the lock body 200 is in the locked position, the positioning assembly 300 moves to the other side of the stopping portion 120, the elastic member 310 drives the matching portion 320 to extend to one side of the stopping portion 120 again, that is, the matching portion 320 is in the extended position again, and the matching portion 320 and the stopping portion 120 form a limit position in the first direction OX, so that the lock body 200 can be stably in the locked position.

That is, when the lock body 200 is switched from the unlocking position to the locking position without being pushed by an external force, the blocking portion 120 can limit the free sliding of the positioning assembly 300 along the first direction OX, and the positioning assembly 300 can only be located on one side of the blocking portion 120, so that the lock body 200 can be positioned. In this embodiment, only the stopping portion 120 is provided, so that the lock body 200 can be positioned at the locking position and the unlocking position, the structure is simple, and the machining difficulty of the lock case is small.

In some embodiments, the lock case 100 is provided with a sliding slot 110, the sliding slot 110 has two slot walls facing each other along the second direction OY, and the stopping portion 120 is disposed on the slot walls and protrudes from the slot walls along the second direction OY; the lock body 200 is slidably engaged with the slide groove 110 in the first direction OX.

Specifically, the first direction OX may be a vertical direction, and the second direction OY may be a horizontal direction. The lock case 100 is a long strip structure, and the lock case 100 is installed on a sash section of a sliding door and window along a vertical direction. The lock body 200 comprises a lock cylinder 210 and a lock hook 220, the lock hook 220 is mounted on the lock body 200, the lock hook 220 extends out of the lock case 100 along a second direction OY, the lock cylinder 210 can slide in the sliding groove 110 along a first direction OX and can drive the lock hook 220 to slide outside the lock case 100 along the first direction OX, and the second direction OY is perpendicular to the first direction OX. The latch hook 220 can be a T-shaped or L-shaped structure, a lock catch is arranged on a frame section of the sliding door and window, a T-shaped or L-shaped hooking groove is formed in the lock catch, the size of the notch of the hooking groove along the first direction OX is larger than the maximum size of the latch hook 220 along the first direction OX, namely, when the fan-shaped groove is closed, the latch hook 220 can stretch into the hooking groove, then the latch hook 210 is pushed along the vertical direction, the latch hook 220 can be driven by the latch hook 210 to be hooked with the hooking groove, and therefore the lock body 200 is located at a locking position.

Referring to fig. 3, in some embodiments, the sidewalls of the stopping portion 120 and the matching portion 320 that are close to each other are arc-shaped. On one hand, the circular arc shape is beneficial to smooth transition of the stopping portion 120 and the matching portion 320, and when the lock cylinder 210 is pushed, the problem that the stopping portion 120 and the matching portion 320 are clamped, so that the positioning assembly 300 fails is prevented; on the other hand, the circular arc structure can reduce the contact area between the stopping portion 120 and the fitting portion 320, so as to reduce the friction force, and further reduce the pushing force required when the lock body 200 is switched between the locking position and the unlocking position.

In some other embodiments, the stopping portion may also be a trapezoid structure, and the matching portion is a trapezoid structure matched with the stopping portion. Specifically, the two trapezoid structures may be isosceles trapezoids with the same size.
