Specific embodiments of the utility model are shown below.

In this embodiment, four corners of the sealing plate 2 are respectively locked on the lock body 1 by screws, so as to realize the detachable installation of the sealing plate 2 and the lock body 1. In other embodiments, the sealing plate 2 and the lock body 1 may be assembled and disassembled by a snap connection or the like.

The fixed end of the elastic pressing piece 4 is riveted on the sealing plate 2 through a rivet 5 so as to realize the relative fixation with the sealing plate 2.

The movable end of the elastic pressing piece 4 is provided with a first bending part 41, the first bending part 41 penetrates out of the lock body 1 and is matched with the outer side of the lock body 1, and the intelligent door lock is assembled on the rear side of the door body 8, the first bending part 41 is extruded by the door body 8 so that the middle section of the elastic pressing piece 4 is deformed to abut against the pressing switch 31, so that the pressing switch 31 is triggered. In this embodiment, the first bending portion 41 is L-shaped and is divided into a contact piece 411 movably contacting the door body 8, and a connecting piece 412 vertically connecting the contact piece 411 and the middle section of the elastic pressing piece 4.

Further, the peripheral surface of the lock body 1 is provided with a skirt 12, the first bending portion 41 is pressed by the door body 8 and then abuts against the skirt 12, and the skirt 12 conceals the first bending portion 41 from view on the inner side surface of the lock body 1.

The second arc-shaped bending part 42 is connected between the middle section of the elastic pressing piece 4 and the fixed end thereof, and the second bending part 42 makes the middle section of the elastic pressing piece 4 deviate from the plane where the fixed end of the elastic pressing piece 4 is located in a direction away from the push switch 31, so that the movable end (i.e., the first bending part 41) of the elastic pressing piece 4 resets when the intelligent door lock is pried.

In this embodiment, the installation cavity 11 is disposed on the back of the lock body 1, and the front of the lock body 1 is provided with the operation panel 7, where the operation panel 7 is electrically connected with the control motherboard 3, and may have functions of inputting a password, unlocking a fingerprint, and the like.

Referring to fig. 5 and 6, the working principle of the present utility model is as follows:

When the intelligent door lock is mounted on the door body 8, the door body 8 contacts with the first bending part 41 of the elastic pressing piece 4, and the first bending part receives downward force (arrow direction in fig. 6) and moves downward along the guide groove 14, so that the middle section of the elastic pressing piece 4 is driven to be gradually deformed below the second bending part 42 (the upper and lower directions refer to fig. 6); simultaneously, the fixed end of the elastic pressing piece 4 is fixed by the sealing plate 2, and the second bending part 42 is supported, so that the middle section of the elastic pressing piece 4 is subjected to downward force, and the pressing switch 31 is pressed down to the triggering stroke.

Under the work (opening) state of the push switch 31, when someone violently pries open the intelligent door lock outside the door, due to the separation of the intelligent door lock and the door body 8, the elastic pressing sheet 4 resets the middle section of the elastic pressing sheet 4 under the elastic action of the second bending part 42, the push switch 31 pops up under the action of the internal spring and resets to the non-triggering state, thereby the control main board 3 obtains an alarm signal, and the triggering alarm realizes the embedded door lock anti-prizing alarm function.

Through the scheme, the elastic pressing piece 4 is arranged between the lock body 1 and the sealing plate 2, the movable end of the elastic pressing piece 4 penetrates out of the lock body 1 and is in movable contact with the door body 8, when the intelligent door lock is in a normal installation state, the elastic pressing piece 4 presses the pressing switch 31 to provide a normal signal, and when the intelligent door lock is pried, the elastic pressing piece 4 is separated from the pressing switch 31 to provide an abnormal signal, so that whether the intelligent door lock is pried or not can be simply judged through the signal of the pressing switch 31, and the main board 3 is controlled to determine whether to send an alarm or not; the elastic pressing sheet 4 is designed in the installation cavity 11 of the lock body 1 in the whole structure, so that the space between the lock body 1 and the door body 8 is not occupied, and the installation space of the door body 8 is hardly additionally required, so that the novel anti-prying intelligent door lock is more suitable for replacing an embedded intelligent door lock product with an anti-prying alarm function at an original door, and can make up for the gap that the original door-replaceable embedded intelligent door lock in the market has no anti-prying function.

The above examples and drawings are not intended to limit the form or form of the present utility model, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present utility model.
