Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, an anti-theft alarm door includes a door frame 1, a door body 2, a door lock (not shown in the figure), an alarm 3 and a trigger assembly 4, wherein the door body 2 is located in the door frame 1 and is hinged to one of the side walls of the door frame 1, and the door lock is arranged on the door body 2 and used for locking the door body 2 on the door frame 1. In this embodiment, the back is closed to the door body 2, and the spring bolt of lock inserts in the spring bolt jack on door frame 1 and the relative one side of articulated shaft, realizes the locking of the door body 2, is prior art as to the concrete structure of lock, no longer gives unnecessary details here.

Referring to fig. 1, in this embodiment, the alarm 3 is disposed on a side of the back of the door frame 1 away from the hinge shaft, and the trigger assembly 4 is disposed on the back of the door body 2 and can move synchronously with the door body 2 to touch and press the start button 301 of the alarm 3, so as to alarm. The specific structure of the alarm 3 is the prior art, and is not described in detail herein.

The anti-theft alarm door of the embodiment has two working modes:

an alarm mode: when the trigger assembly 4 is located at the trigger position, the trigger assembly is driven to touch and press a start button of the alarm 3 in the process that the door body 2 is opened outwards, a control circuit in the alarm 3 is started, and the alarm 3 is controlled to give out alarm sound to realize alarming;

non-alarm mode: when the trigger component 4 is switched to the non-trigger position, the alarm is not triggered by the trigger component 4 in the process that the door body 2 is opened outwards, and the door body 2 can be opened normally.

The embodiment triggers the alarm device to send out alarm sound through the relative movement of the door frame 1 and the door body 2 so as to achieve the anti-theft purpose, and has the advantage of simple structure.

In practical application, the triggering assembly 4 includes a pressing rod 401, a rotating shaft 402 and a locking assembly for locking the pressing rod 401 at a triggering position, a sleeve 5 is vertically installed on the back surface of the door body 2, the rotating shaft 402 is rotatably installed in the sleeve 5, the top end of the rotating shaft extends out of the sleeve 5, the pressing rod 401 is transversely arranged at the top of the rotating shaft 402, one end of the pressing rod 401 is fixedly connected with the rotating shaft 402, and the other end of the pressing rod 401 is bent towards the door body to form a triggering end a for triggering and pressing the starting button 301;

the locking assembly comprises a clamping groove 403 which is arranged on the sleeve 5 and has an upward opening, and a blocking rod 404 which is arranged on the pressing rod 401 and is matched with the clamping groove 403, wherein the blocking rod 404 rotates into the clamping groove 403 along with the rotating shaft 402, and the triggering end a is opposite to the starting button 301.

According to the embodiment, the pressing rod 401 can rotate the triggering end to the outside of the door body 2 through the driving of the rotating shaft 402, when the blocking rod 404 is clamped into the blocking groove 403, the rotating shaft 402 cannot rotate continuously due to the blocking of the blocking groove 403 and is limited, at the moment, the triggering end a is opposite to the starting button 301, and therefore the pressing rod is limited at the triggering position. When the door body 2 is opened outwards, the triggering end a is driven by the door body 2 to move towards the alarm 3 and touch the starting button 301, so that the alarm is realized. When rotating trigger end a to in the door body 2 back, when the door body 2 was outwards opened, trigger end a can not touch start button 301, and door body 2 can normally be opened, and the burglar alarm door does not report to the police.

Referring to fig. 1, in an embodiment, a spring 6 is further disposed between the sleeve 5 and the rotating shaft 402, a shaft shoulder 7 is disposed on the rotating shaft 402, a retainer ring 8 is fixedly disposed on the inner wall of the sleeve 5 above the shaft shoulder 7, two ends of the spring 6 respectively abut against the shaft shoulder 7 and the retainer ring 8, when the trigger end a presses the start button 301, the rotating shaft 402 is driven by the pressing rod 401 to move axially and compress the spring 6, when the door body continues to be opened outward, the spring 6 is continuously compressed, and when the elastic compression force reaches the trigger start button 301, the alarm 3 is started to give an alarm; when the door body 2 is closed inwards, the rotating shaft is reset under the action of the spring. In order to prevent the locking assembly from being locked and failed, the design length of the stop lever 404 is satisfied, and the stop lever 404 can not be drawn out from the side of the card slot in the process from the moment that the pressing lever 401 touches the starting button 301 to the moment that the alarm 3 is triggered to give an alarm.

Specifically, the top of the rotating shaft 402 is provided with a screw 9, the pressing rod 401 is sleeved on the screw 9 and locked by a nut assembly 10, and the sleeve 5 is connected to the door body 2 through a bolt assembly penetrating through a connecting flange of the sleeve.

The above examples are merely illustrative of the present invention clearly and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Nor is it intended to be exhaustive of all embodiments. And obvious changes and modifications may be made without departing from the scope of the present invention.
