detailed description

Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". The following descriptions in the specification are preferred implementation modes for implementing the present utility model, but the description is for the purpose of illustrating the general principles of the present utility model, and is not intended to limit the scope of the present utility model. The scope of protection of the present utility model should be defined by the appended claims.

The utility model will be described in further detail below in conjunction with the accompanying drawings, but not as a limitation to the utility model.

Example

As shown in Figures 1-3 and Figure 6, the smart door lock device disclosed by the utility model includes a main body 1, a driving head 2, a rack 3, a pressing plate 7 and a fixing plate 8;

The fixing plate 8 is arranged in the main body 1, the pressing plate 7 is pivotally connected with the main body 1 through the rotating shaft 9, and the pressing plate 7 is slidably connected together through the positioning groove 6 on the fixing plate 8 and the return spring 5, The pressing plate 7 can be reset after the pressing operation;

The drive head 2 is rotatably arranged on the fixed plate 8, the chute 32 provided by the rack 3 is slidably arranged on the fixed plate 8 through the positioning pin 4, and the number of the drive head 2 provided Convex teeth 21 and rack 3 are provided with a number of concave teeth 31 through gear meshing connection, and the drive head 2 is provided with a polygonal shaft hole 22 which is a square;

A first driving bar 71 is arranged on the pressing plate 7 , and a second driving bar 10 is arranged between the first driving bar 71 and the rack 3 .

Preferably, as shown in FIG. 4 and FIG. 5 , the second driving bar 10 is installed in the second track hole 34 provided on the rack 3 or the second driving bar 10 is installed on the first driving bar 71 above. Inside the track hole 72.

When the pressing plate 7 is pressed, the first drive bar 71 drives the second drive bar 10 to drive the rack 3 to slide down along the chute 32, so that the rack 3 drives the drive head 2 to rotate, and the drive head 2 is provided with The polygonal drive shaft arranged in the polygonal drive shaft hole 22 drives the lock core to rotate and unlock.
