Referring to fig. 1 to 5, a first embodiment of the present utility model is as follows: a locking device can be installed at a cabinet door, a sliding window, a pushing window and other places needing to be prevented from being opened accidentally by children.

Referring to fig. 1 to 3 and 5, the latch device includes a housing 1, and a button 2, a first elastic member 3, an insert 4 and a slider 5 respectively disposed in the housing 1, wherein the button 2, the insert 4 and the slider 5 are respectively slidable relative to the housing 1, and a partial area of the button 2 and a partial area of the slider 5 are respectively exposed out of the housing 1; the insert block 4 has an insert portion 41, and the slider 5 has a slot 51 that mates with the insert portion 41; the shell 1 is provided with a locking opening 61, the sliding piece 5 is provided with a locking piece 52, and a locking area 62 for locking the external lock head 201 is formed by surrounding the locking opening 61 and the locking piece 52; the button 2 is used for driving the insert 4 to slide so as to enable the insert 41 to withdraw from the slot 51, the first elastic member 3 is used for driving the button 2 to reset, and the first elastic member 3 contacts the housing 1 so that the housing 1 can provide support for the first elastic member 3.

When the locking device is unlocked, the pressing operation and the sliding operation are needed, so that the cracking difficulty of children is greatly improved. As a preferred embodiment, the exposed area of the button 2 is located on a different face of the housing 1 than the area of the button 2 of the slider 5, which may be more difficult for a child to operate.

In some embodiments, the button 2 and the insert 4 may be directly connected, or may be indirectly connected through other structures, and when the button 2 and the insert 4 are directly connected, the button 2 and the insert 4 may be integrally formed as a one-piece structure, or may be connected by glue, threads, a buckle, or a fastener.

Referring to fig. 1 and fig. 3, in other embodiments, the sliding track of the sliding member 5 may be linear, and in this embodiment, in order to further increase the difficulty of cracking by a child, the sliding track of the sliding member 5 is purposely configured to be arc-shaped.

As shown in fig. 2, the locking opening 61 communicates with the bottom surface and one side surface of the housing 1. In other embodiments, the inner wall surface of the locking piece 52 may be planar, i.e. the locking area 62 is generally rectangular, and the locking device may be applied to a cabinet door, a window or other application scenarios where the external lock 201 enters and exits the locking area 62 in a translational manner. Referring to fig. 2, 3 and 5, in this embodiment, the inner wall surface of the locking piece 52 has a locking groove, optionally, the cross section of the locking piece 52 is L-shaped, concave-shaped or other shapes, and correspondingly, the external lock 201 is L-shaped or other shapes capable of forming a snap fit with the locking piece 52. At this time, the locking device may be applied not only to an application scenario in which the external locking head 201 enters and exits the locking area 62 in a translational manner, but also to an application scenario (such as a sliding window) in which the external locking head 201 enters and exits the locking area 62 in an arc motion manner.

As shown in fig. 3, optionally, a second elastic member 7 for driving the insert block 4 to return is further provided in the housing 1. The provision of the second elastic member 7 allows the insertion portion 41 of the insert 4 to be more stably inserted into the insertion groove 51, thereby better locking the slider 5.

The second elastic member 7 is a spring, a spring piece, a rubber block or other elastic structural members, and similarly, the first elastic member 3 is a spring, a spring piece, a rubber block or other elastic structural members.

Referring to fig. 1, 3 and 4, in order to further improve the breaking difficulty of the latch device and to better prevent the misoperation of children, in this embodiment, a coded lock mechanism 8 is disposed in the housing 1, the coded lock mechanism 8 includes a lock shaft 81 and a coded wheel assembly 82 rotatably disposed on the lock shaft 81, a part of a region of the coded wheel assembly 82 is exposed out of the housing 1, a limiting block 811 is disposed on the lock shaft 81, a limiting groove 8211 is disposed on an inner wall of the coded wheel assembly 82, and when the limiting block 811 is aligned with the limiting groove 8211, the coded wheel assembly 82 is slidable relative to the lock shaft 81 along an axial direction of the lock shaft 81; the button 2 is in transmission connection with the lock shaft 81, and the first elastic piece 3 drives the button 2 to reset by driving the lock shaft 81 to reset. It will be appreciated that the locker is triple-secured by first adjusting the combination wheel assembly 82 to the correctly unlocked state, then pressing the button 2, and finally sliding the slider 5 to unlock the locker. This can make the latch more complex to break, making it more difficult for a child to accidentally unlock the latch.

Preferably, the number of the combination wheel assemblies 82 in the combination lock mechanism 8 is plural, in this embodiment, the number of the combination wheel assemblies 82 is three, and three of the combination wheel assemblies 82 are arranged at intervals. Specifically, the lock shaft 81 has three limiting blocks 811, and the three limiting blocks 811 are in one-to-one correspondence with the three code wheel assemblies 82.

In order to make the internal structure of the locking device more compact so as to control the whole volume of the locking device, in this embodiment, a rotating member 9 is further provided in the housing 1, the rotating member 9 is rotationally connected with the housing 1, one end of the rotating member 9 is located between the button 2 and the lock shaft 81, the other end of the rotating member 9 forms a driving portion 91, and the insert 4 is provided with a matching portion 42 that is matched with the driving portion 91, optionally, the driving portion 91 is a block-shaped protrusion, and the matching portion 42 is a groove. Specifically, one end of the rotating member 9 located between the button 2 and the lock shaft 81 is respectively in contact with the button 2 and the lock shaft 81, and only when the limiting block 811 is aligned with the limiting groove 8211, the user can press the button 2, otherwise, the limiting block 811 on the lock shaft 81 will abut against the end surface of the code wheel assembly 82, the lock shaft 81 cannot slide along the axial direction of the code wheel assembly 82, and the rotating member 9 cannot rotate, so that the insert 4 cannot be driven, and the insert 41 cannot exit the slot 51.

Please combine fig. 3 and fig. 4, in order to improve the operation feel of the combination wheel assembly 82, a plurality of straight slots 8221 are uniformly distributed on the outer peripheral wall of the combination wheel assembly 82, the length direction of the straight slots 8221 is consistent with the axial direction of the combination wheel assembly 82, and an elastic clamping structure 10 matched with the straight slots 8221 is disposed in the housing 1. When the elastic clamping structure 10 extends into the straight slot 8221, it collides with the code disc 822, so as to generate sound, and further make the code lock mechanism 8 have stronger mechanical operation feeling. In some embodiments, the elastic latching structure 10 may be a spring.
