Description

Technical Field

[0001] This utility model relates to a square lock tongue mounting structure for use in smart door locks. Background Technology

[0002] In the current smart lock industry, the square bolt is installed on the lock body using an assembly. Specifically, the assembly is first installed inside the lock body, then the square bolt is inserted into the lock body through the bolt mounting hole on the outside of the housing, and finally the square bolt is fixed to the assembly using a connector. In actual production, this method is cumbersome and inconvenient, which significantly impacts the production and assembly efficiency of smart locks.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a square lock tongue mounting structure for smart door locks, which enables quick installation of the square lock tongue.

[0005] To achieve the above objectives, this utility model provides a square latch mounting structure for smart door locks, which includes a housing and a square latch. The square latch is connected to a latch mounting plate. The side of the housing is provided with a latch mounting hole that mates with the square latch. The latch mounting plate can extend into the housing through the latch mounting hole. The latch mounting plate has a travel groove that extends along the movement direction of the square latch. The housing is provided with a connecting part that passes through the travel groove.

[0006] In one or more embodiments, the connecting part is a connecting post, and a screw is connected to the connecting post. The screw is provided with a pad that can press and hold the locking tongue mounting plate.

[0007] In one or more embodiments, the square latch and the latch mounting plate are fixed together by riveting or welding.

[0008] In one or more embodiments, a circuit board is provided inside the housing, a photosensitive switch is provided on the circuit board, and a detection baffle for triggering the photosensitive switch is provided on the latch mounting plate.

[0009] In one or more embodiments, the number of photosensitive switches is two, and the two photosensitive switches are distributed at intervals along the movement direction of the square locking tongue.

[0010] In one or more embodiments, the detection baffle is fixed to the latch mounting plate by welding.

[0011] Compared with the prior art, the advantages of this utility model are: after adopting this installation structure, the installation steps of releasing the lock tongue can be simplified, the use of parts can be reduced, the production cost can be reduced, and the production efficiency of smart door locks can be significantly improved.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] See appendix Figure 1-3 This application provides a square latch mounting structure for smart door locks, comprising a housing 1 and a square latch 2. The square latch 2 is connected to a latch mounting plate 3, and the square latch 2 and the latch mounting plate 3 are fixed together by riveting or welding. The side of the housing 1 is provided with a latch mounting hole that mates with the square latch 2. The latch mounting plate 3 can extend into the housing 1 through the latch mounting hole. The latch mounting plate 3 has a travel groove 4 that extends along the movement direction of the square latch 2. The housing 1 is provided with a connecting part that passes through the travel groove 4. During installation, the production worker holds the square latch, aligns the latch mounting plate with the latch mounting hole, inserts it into the housing, and fits the travel groove onto the connecting part. This structure enables the rapid installation of the square latch, reduces the need for component intervention during installation, and improves production efficiency.

[0017] The connecting part is a connecting post, and a screw 5 is connected to the connecting post. The screw is equipped with a pad 6 that can press and hold the lock tongue mounting plate. The pad is fitted on the screw, and the screw is connected to the connecting post, which can press and hold the lock tongue mounting plate and prevent the lock tongue from shaking during daily use.

[0018] The housing 1 contains a circuit board 7, on which a photosensitive switch 8 is mounted. The latch mounting plate 3 has a detection baffle 9 that triggers the photosensitive switch. By using the detection baffle and the photosensitive switch in conjunction, the current working state of the square latch can be determined. In this embodiment, there are two photosensitive switches 8, which are spaced apart along the movement direction of the square latch 2. One photosensitive switch corresponds to the state where the square latch is fully inserted into the housing, and the other photosensitive switch corresponds to the state where the square latch is extended out of the housing.

[0019] The detection baffle 9 is specifically fixed to the latch mounting plate 3 by welding.

[0020] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
