[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "clockwise" and "counterclockwise" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] like Figure 1 and Figure 2 As shown, a pet cage door lock comprises a shell 1, a lock tongue 2 and an elastic member 3. The lock tongue 2 is in the form of a sheet and is slidably arranged in the shell 1. The top end of the lock tongue 2 can extend out of the shell 1 or be retracted into the shell 1. An operation window 11 is provided on the shell 1. A plurality of positioning grooves 21 are provided on the side of the lock tongue 2. At least one elastic member 3 is arranged in the shell 1. The elastic member 3 can be inserted into the positioning groove 21 to limit the movement of the lock tongue 2.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the shell 1 is in the shape of a thin sheet, and the projection shape of the shell 1 is not limited. A mounting groove 12 is provided in the shell 1, and the rear end surface of the shell 1 is open. A rear cover 4 is detachably provided on the rear end surface of the shell 1.

[0031] The locking tongue 2 is arranged in the mounting groove 12. The top of the shell 1 is provided with a first opening 13 connected to the mounting groove 12. The locking tongue 2 can slide up and down in the mounting groove 12 so that the top of the locking tongue 2 extends out of the first opening 13, or the locking tongue 2 is retracted into the mounting groove 12.

[0032] An elastic member 3 is disposed in the mounting groove 12, and two positioning grooves 21 are respectively provided on the left and right sides of the lock tongue 2. The elastic member 3 can be inserted into the positioning grooves 21. The two positioning grooves 21 correspond to two states of the lock tongue, namely, the extended state and the retracted state. The elastic member 3 can be a leaf spring, a retaining spring, an elastic buckle, etc. The elastic member 3 is an elastic structural member that is inserted into the positioning groove by elastic force to limit the movement of the lock tongue.

[0033] An operating window 11 is provided on the front of the housing 1, and the operating window 11 is connected to the mounting groove 12. The user's finger can pass through the operating window 11 and directly contact the lock tongue 2 to move the lock tongue 2 to extend or retract the lock tongue 2 to lock or unlock the pet cage door.

[0034] Preferably, the lock tongue 2 is provided with a second opening 22 that matches the operation window 11 , and the user can push the lock tongue 2 to move through the second opening 22 .

[0035] In another preferred embodiment, a handle is provided on the lock tongue 2, and the handle passes through the operation window 11, and the user can push the lock tongue to move by the handle.

[0036] Preferably, four protrusions 121 are provided in the mounting groove 12, and two protrusions 121 are respectively distributed on the left and right sides of the lock tongue 2. The protrusions 121 can limit the left and right positions of the lock tongue 2 so that the lock tongue 2 will not deviate to the left and right sides when moving up and down.

[0037] In practical applications, such as Figure 4 and Figure 5 As shown, the housing 1 is provided with a plurality of mounting holes, through which the door lock can be mounted on the cage door 6, and the cage body 5 is provided with a card slot 51 that cooperates with the lock tongue 2. The door lock can be set in any position, for example, the door lock can be set on the cage body, and the card slot can be set on the cage door.

[0038] During use, the user pushes the lock tongue 2 to move so that the lock tongue 2 extends out and is inserted into the card slot to lock the cage door 6; or the user retracts the lock tongue 2 into the installation slot 12 to unlock the cage door 6.

[0039] Embodiment 2:

[0040] This embodiment is based on the first embodiment, and the main difference lies in the structure of the elastic member 3 .

[0041] like Figure 2 As shown, in this embodiment, the elastic member 3 is a wavy spring leaf, which has at least one crest (protrusion) that cooperates with the positioning groove 21, and the spring leaf is stuck between the protrusion 121 and the inner wall of the mounting groove 12, and the crest (protrusion) can pass through the gap between the protrusions and be inserted into the positioning groove 21.

[0042] The positioning groove 21 is in the shape of a semicircle that is concave inwards, and the crest is an arc-shaped convex shape.

[0043] When an external force is applied to push the lock tongue 2 to move, the positioning groove 21 will press the spring sheet outwards, so that the wave crest is separated from the positioning groove 21 until the wave crest is inserted into another positioning groove 21 .

[0044] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
