[0025] First of all, it should be noted that: in the present embodiment, the lock body 1 and the lock tongue 2 are transversely inserted, that is, the insertion hole 121, the boss 13, the insertion section 21 and the locking section 22 are all transversely arranged, and the door body is opened or closed from left to right or from right to left relative to the door frame, so the length, width and height can be used to describe the size.

[0026] As shown in Figures 1 to 3 A lock with a guide function applied to a closable door body and a door frame, comprising a lock body 1 arranged on the door frame and a lock tongue 2 arranged on the door body, the lock body 1 is provided with an insertion hole 121 and a boss 13 arranged at the front end of the insertion hole 121 and facing the lock tongue, the end of the boss 13 facing the lock tongue 2 is provided with a first slope 131, the lock tongue 2 comprises an insertion section 21 and a locking section 22 connected to the insertion section 21, the front end of the insertion section 21 is provided with a second slope 211, and the heights of the insertion hole 121, the boss 13, the locking section 22 and the insertion section 21 decrease in turn, so that the insertion section 21 and the locking section 22 enter the insertion hole 121 along the boss 13.

[0027] Through the above scheme, the lock catch of the embodiment in actual application, the lock tongue 2 and the lock catch main body 1 correspond to each other, so that the lock tongue 2 can be inserted or pulled out, so that the door body is closed or opened relative to the door frame, when the door body drives the lock tongue 2 to insert into the lock catch main body 1, the door body appears the phenomenon of drooping after long time use, that is, the door body is inclined and the lock tongue 2 is also inclined, based on the height of the insertion hole 121 and the boss 13 is greater than the height of the insertion section 21, therefore, the insertion hole 121 has enough space to provide the boss 13 to place, and the insertion section 21 can enter the insertion hole 121 along the boss 13, then the lock tongue 2 is accurately guided into the lock catch main body 1 under the sliding assistance of the second inclined surface 211 of the insertion section 21 and the first inclined surface 131 of the boss 13, realizes the lock tongue 2 is guided and the lock catch main body 1 is clamped, so that the door body can be closed with the door frame in the case of drooping.

[0028] The lock catch in the embodiment is horizontally arranged, the first inclined surface 131 and the second inclined surface 211 are arranged in the same direction, the insertion section 21 is a trapezoidal block, and the locking section 22 is a rectangular block. Of course, there are door and door frame matching structures that open and close from top to bottom or from bottom to top on the market, and the lock catch of the application is also applicable. At this time, the lock catch is only arranged vertically, and the first inclined surface 131 and the second inclined surface 211 are also arranged vertically. Based on the above, the door body will tilt to the left or right relative to the door frame, and the lock tongue 2 can be accurately guided into the lock catch main body 1 under the assistance of the first inclined surface 131 and the second inclined surface 211, realizing the closure of the vertically opening and closing door and door frame, and improving the practicability and diversity of the lock catch.

[0029] As shown in Figure 1 , as an improved specific embodiment, the width of the insertion hole 121 is greater than the width of the insertion section 21 and the locking section 22. Specifically, since the door body appears drooping, not only the lock tongue 2 is lowered, but also the lock tongue 2 is laterally offset, so the height and width of the insertion hole 121 are much greater than the insertion section 21, which can ensure the insertion of the lock tongue 2, and when the door body droops more, the lock tongue 2 can be corrected as much as possible to be accurately guided into the lock catch main body 1, realizing the closure of the door body and the door frame.

[0030] As shown in Figure 2 and Figure 3As shown, as an improved embodiment, the cross section of the insertion hole 121 is Y-shaped structure, and the cross section of the insertion section 21 is trapezoidal structure. Specifically, including but not limited to, the insertion hole 121 is composed of a small hole and a large hole, the large hole is trumpet-shaped, the boss 13 is arranged at the front end bottom surface of the insertion hole 121, that is, the boss 13 is at the large hole, and the insertion section 21 and the small hole are arranged in a straight line, at this time, the boss 13 is below the insertion section 21. Under normal conditions, the insertion section 21 can directly pass through the large hole and then enter the small hole. Only in the case of downward deflection of the locking tongue 2, the insertion section 21 will be in contact with the boss 13. The boss 13 can be a triangular shape with a circular arc or an arc section structure, which is beneficial to reduce the friction between the insertion section 21 and the boss 13, avoid scratching the locking tongue 2, and ensure the service life of the locking tongue 2. At the same time, the boss 13 is an integral structure with the lock body 1.

[0031] As shown in Figure 1 and Figure 2 As shown, as an improved embodiment, the lock body 1 includes a first fixed block 11 and a connecting block 12 perpendicular to the first fixed block 11, the connecting block 12 passes through the first fixed block 11, the insertion hole 121 is arranged on the connecting block 12, and the first fixed block 11 is provided with at least two first fixed holes 111. Specifically, including but not limited to, the first fixed block 11 and the connecting block 12 are integrally stamped and formed, the connecting block 12 is arranged at the center of the first fixed block 11, the first fixed block 11 and the connecting block 12 are both rectangular blocks, and the connecting block 12 is partially protruded relative to the surface of the first fixed block 11. This can ensure that the opening of the insertion hole 121 is widened, avoid that the insertion hole 121 of the connecting block 12 is too large to affect the overall strength of the lock body 1, and the first fixed hole 111 is provided with two screw holes. The two first fixed holes 111 are arranged on the upper and lower sides of the connecting block 12, and the door frame is correspondingly provided with a mounting groove. The lock body 1 can be fixed in the mounting groove through screws, which is beneficial to the quick disassembly and assembly of the lock and the later maintenance.

[0032] As shown in Figure 2 As shown, as an improved embodiment, the boss 13 is connected with the connecting block 12, and the inclination angle of the first inclined surface 131 is 50 degrees. Specifically, the boss 13 and the connecting block 12 are integrally stamped and formed. The first inclined surface 131 at this angle can not only reduce the opposite force between the locking tongue 2 and the boss 13 to avoid damage caused by excessive extrusion, but also make the first inclined surface 131 extend upward and downward to be wide enough. The structure is reasonable. It is worth noting that the direction in which the locking tongue 2 is inserted towards the lock body 1 is the front view. Therefore, when the inclination angle of the first inclined surface 131 is 50 degrees, it is based on the right view of the lock to explain.

Based on this, when the insertion section 21 enters and extrudes the tail of the latch, the head of the latch is inserted into the lock hole 221, and under the action of the spring, the latch is prevented from loosening, so as to lock the lock body 1 and the lock tongue 2. When the tail of the latch is subjected to pressure in the opposite direction due to the entry of the insertion section 21, the latch is pulled out of the lock hole 221. In this process, the latch can also push out the insertion section 21, so as to release the lock body 1 and the lock tongue 2.

[0034] As shown, Figure 3 As shown, as an improved specific embodiment, the lock tongue 2 further includes a second fixed block 23, the second fixed block 23 is perpendicularly connected with the locking section 22, and the second fixed block 23 is provided with at least two second fixed holes 231. Specifically, the second fixed block 23 is a rectangular block, the insertion section 21 and the locking section 22 are arranged in a straight line and are in an integrated structure, so that the insertion section 21 is also perpendicular to the second fixed block 23, and the locking section 22 is arranged at the center of the second fixed block 23, so that the insertion section 21, the locking section 22 and the second fixed block 23 form a T-shaped structure, and the insertion section 21, the locking section 22 and the second fixed block 23 are integrally stamped and formed, the second fixed holes 231 are two screw holes, and the two second fixed holes 231 are arranged on the upper and lower sides of the locking section 22.
