[0019] The horizontal, up and down in this application document are based on the attached Figure 1-4 To explain, the direction description can change according to the actual situation.

[0020] See also Figure 1-4 The utility model provides a latch, comprising:

[0021] A first locking element 100;

[0022] A second locking element, disposed on one side of the first locking element 100;

[0023] The second locking element comprises a plug 210, an elastic component and a mounting portion 220. The plug 210 and the elastic component are arranged on the mounting portion 220. The plug 210 can be close to or away from the first locking element 100 relative to the mounting portion 220. The elastic component is arranged on one side of the plug 210.

[0024] One side of the plug 210 is set as an inclined surface, so that when the plug 210 is locked from the outside of the first locking element 100, the inclined surface of the plug 210 and the first locking element 100 interact with each other to make the plug 210 retract, the plug 210 squeezes the elastic component and drives the plug 210 to have a tendency to approach the first locking element 100, and after the plug 210 enters between the first locking element 100 and the second locking element, it rebounds and locks under the action of the elastic component.

[0025] In this embodiment, one side of the plug 210 is set as an inclined surface, and the plug 210 is indirectly driven by the elastic component to form a tendency to approach the first lock 100, so that when the pet cage door or the like is rotated to close, the inclined surface preferentially contacts the first lock 100 and is squeezed after abutting. After the elastic component is compressed, the plug 210 has a tendency to approach the first lock 100. After the plug 210 enters between the first lock 100 and the second lock, it rebounds and locks under the action of the elastic component, thereby realizing automatic locking. There is no need to operate when closing, which is easy to operate. In addition, in an emergency, when a ferocious pet is imprisoned, the lock can be directly locked to avoid repeated opening.

[0026] In one embodiment, the elastic component includes a mounting member 232 and a first spring 231, wherein the mounting member 232 is installed in the mounting portion 220, the mounting member 232 is connected to the plug 210, and the first spring 231 acts on the mounting member 232 to drive the plug 210 to have a tendency to approach the first locking member 100.

[0027] In this embodiment, the plug 210 is indirectly connected to the first spring 231 through the mounting member 232, and there is space for operating the socket to unlock, that is, the plug 210 can be indirectly controlled by operating the mounting member 232, which is more convenient to use.

[0028] In one embodiment, the first spring 231 is disposed on a side of the mounting member 232 away from the plug 210, and the first spring 231 makes the plug 210 tend to approach the first locking member 100 after the plug 210 is squeezed; or

[0029] The first spring 231 is disposed at one end of the mounting member 232 close to the plug 210 . The first spring 231 makes the plug 210 tend to approach the first locking member 100 after the plug 210 is squeezed.

[0030] In this embodiment, the first spring 231 has two settings, one is to be set at an end of the mounting member 232 away from the plug 210, and the other is to be set at an end of the mounting member 232 close to the plug 210. Both of these can achieve that after the plug 210 is squeezed, the plug 210 has a tendency to approach the first locking member 100, thereby achieving automatic locking.

[0031] Specifically, the two ends of the first spring 231 are respectively connected to the mounting member 232 and the mounting portion 220, wherein the first spring 231 can be fixedly connected or abutted when it is at one end of the mounting member 232 away from the plug 210, and the first spring 231 must be fixedly connected or sleeved when it is close to one end of the mounting member 232 of the plug 210.

[0032] In one embodiment, the mounting member 232 is provided with a supporting portion extending outward.

[0033] In this embodiment, the force-reinforcing portion is provided to facilitate operation of the plug 210 .

[0034] In one embodiment, the mounting portion 220 is hollow, and the plug 210 and the elastic component are both arranged in the mounting portion 220. A first through hole 221 is arranged on the outer side of the mounting portion 220. The force-reinforcing portion passes through the first through hole 221. The first through hole 221 has a first lateral extension length. The force-reinforcing portion moves in the first through hole 221 toward a side away from the first locking element 100 to release the locked state of the plug 210.

[0035] In this embodiment, the mounting portion 220 is hollowed out to protect the plug 210 and the elastic component and to make the connection between the plug 210 and the elastic component more stable. After the force portion passes through the first through hole 221, the operator can indirectly control the lateral movement of the plug 210 by operating the force portion. Specifically, when unlocking, the plug 210 can be controlled to move away from the first locking element 100 by operating the force portion.

[0036] Specifically, the distance that the force-applying portion is moved from one end of the first through hole 221 in the unlocking direction to just unlocking is set as the unlocking length, and the first lateral extension length is greater than or equal to the unlocking length.

[0037] In one embodiment, a locking assembly is further included. The locking assembly is disposed in the mounting portion 220 and is used to lock the plug 210 in an unlocked state.

[0038] In this embodiment, by setting a locking component, the unlocked state of the plug 210 can be locked and cannot be locked, which is convenient for use when it needs to be normally open.

[0039] In one embodiment, the locking assembly includes a second spring 410 and a button 420, the mounting portion 220 is provided with a second through hole on the outer surface, the mounting member 232 is provided with a third through hole 2321, one end of the button 420 and one end of the second spring 410 are connected through the third through hole 2321, the other end of the button 420 passes through the second through hole, and the other end of the second spring 410 is connected to the mounting portion 220;

[0040] The third through hole 2321 has a second lateral extension length, and the second lateral extension length is greater than or equal to the first lateral extension length;

[0041] A first limiting member is disposed between the button 420 and the mounting member 232 , and the first limiting member is used to lock the plug 210 after it enters the unlocked state. The button 420 is used to release the unlocked state of the plug 210 after being pressed.

[0042] In this embodiment, by designing the button 420 and the second spring 410, the second spring 410 gives the button 420 an upward lifting force, and the two are connected through the third through hole 2321. The movement of the hand 300 can not only operate the plug 210, but also change the relative position of the button 420 in the third through hole 2321. When the plug 210 enters the unlocked state, the lifting force of the second spring 410 will cause the first limit member to fix the mounting member 232, thereby locking the unlocked state of the plug 210. After the button 420 is pressed, the first limit member and the mounting member 232 are released, and the plug 210 can be pushed by the first spring 231.

[0043] The design of the button 420 allows the plug 210 to enter two states, which can be changed according to the actual use state.

[0044] In a preferred embodiment, the second lateral extension length is equal to the first lateral extension length. To enter the unlocked state, the hand portion 300 only needs to be moved away from the first locking member 100, and the first limiting member needs to enter a predetermined position, thereby locking the button 420 and the mounting member 232, and limiting the movement of the mounting member 232. When the lock needs to be released, the button 420 can be pressed.

[0045] In one embodiment, the first limiting member is a first protrusion, which is arranged at one end of the button 420 connected to the second spring 410. After the plug 210 enters the unlocked state, the first protrusion engages with the mounting member 232 or the second through hole to lock the plug 210 in the unlocked state.

[0046] In this embodiment, the first limiter is designed at one end of the button 420 connected to the second spring 410, and can be engaged with the mounting member 232 or the second through hole to achieve locking after the plug 210 enters the unlocked state.

[0047] In one embodiment, a receiving opening 23211 having a shape and size corresponding to the first protrusion is provided on the third through hole 2321 or the mounting member 232. When the button 420 moves to the receiving opening 23211 relative to the mounting member 232 through the third through hole 2321, the button 420 is lifted up by the second spring 410 and the first protrusion is stuck in the receiving opening 23211. The button 420 is restricted and cannot move laterally in the third through hole 2321, thereby locking the plug 210 in an unlocked state.

[0048] In this embodiment, if the accommodating port 23211 is disposed in the third through hole 2321, there are several situations that can limit the button 420 from moving relative to the mounting member 232. First, a limiting block 500 is disposed between the mounting portion 220 above the accommodating port 23211 and the mounting member 232. The limiting block 500 is connected to the button 420 and moves synchronously. The longitudinal length of the accommodating port 23211 is greater than the longitudinal length of the third through hole 2321. Under normal circumstances, the button 420 can move relative to the mounting member 232 in the third through hole 2321. After moving until the first protrusion is aligned with the accommodating port 23211, the first protrusion is lifted up and stuck in the accommodating port 2321. The top limiting block 500 limits further upward movement, and the button 420 is limited to move relative to the mounting member 232 in the third through hole 2321. Second, the limiting block 500 is a limiting plate disposed at the top of the accommodating port 23211 and connected to the mounting member 232.

[0049] In one embodiment, a second protrusion is provided at the bottom of the mounting member 232, and a groove corresponding to the shape and size of the second protrusion is provided on the side of the first protrusion facing the mounting member 232. When the first protrusion is engaged with the second protrusion through the groove, the plug 210 is locked in an unlocked state.

[0050] In this embodiment, lateral movement restriction is achieved by engaging the groove and the protrusion at a preset position.

[0051] In one embodiment, the mounting side of the mounting portion is provided with a screw mounting hole, and is mounted on the door by means of screws.

[0052] In one embodiment, the mounting side of the mounting portion can be mounted on the door by glue.

[0053] In one embodiment, the mounting side of the mounting portion is snap-connected with a hanger, and is installed via snap-fit ​​protrusions (which may be screws, nails, etc.) on the hanger and the door.

[0054] The specific usage of the above embodiment is as follows:

[0055] The locked state is the state in which the plug 210 is pushed by the first spring 231 and naturally moves to the left. In this state, if the plug 210 is not stuck in the first lock 100, it can rebound and lock when the door is closed; when the door is to be kept open, the handle 300 can be pulled to the end away from the first lock 100, so that the first protrusion enters the predetermined position and plays a locking role, restricting the movement of the mounting member 232. At this time, the plug 210 is locked in the mounting portion 220 and cannot cooperate with the first lock 100 to lock the door.

[0056] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
