In the description of the present invention, a plurality means two or more. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

In the description of the embodiment of the present invention, for convenience of expression, the first direction refers to a direction in which the first bolt extends and retracts along the lock body, and the second direction refers to a direction perpendicular to the direction in which the first bolt extends and retracts along the lock body.

Referring to fig. 1, an embodiment of the present invention provides a door lock 100, including a lock body 110 and a first locking device, where the first locking device includes a first bolt 210 and a moving assembly 220, one end of the first bolt 210 is provided with a convex arc surface, and the other end is connected with the moving assembly 220, and it should be noted that the connection may be a fixed weld, or a bolt connection, which is not limited herein. When the first bolt 210 is acted by external force, the moving assembly 220 moves inward to complete the retraction of the first bolt 210 inward to achieve the unlocking state, and when the external force disappears, the moving assembly 220 extends the first bolt 210 outward to achieve the locking state, so that the first bolt 210 is locked.

The moving assembly 220 includes a moving element 2201, a second position-limiting element 2202 and a resetting element 2203, wherein the second position-limiting element 2202 is installed at one end of the moving element 2201 away from the first lock tongue 210, and the resetting element 2203 is installed between the first lock tongue 210 and the second position-limiting element 2202 for resetting the position of the first lock tongue 210 relative to the lock body 110. Referring to fig. 1, the first locking device 200 is movably installed on the lock body 110, and the first locking tongue 210 is forced to move the first locking device 200 into the lock body 110, so as to achieve the unlocked state. The first position-limiting member 120 is disposed in the lock body 110 for limiting the relative position of the second position-limiting member 2202 with respect to the lock body 110, and it is understood that the position of the first locking device 200 with respect to the lock body 110 is also limited. The second limiting member 2202 is movably matched with the first limiting member 120, and it can also be understood that the second limiting member 2202 can move relative to the first limiting member 120, and the first limiting member 120 limits the moving distance of the second limiting member 2202.
