Description

 Door handle anti-theft device  

The invention relates to an anti-theft device, in particular to a door handle anti-theft device.

At present, the prior art door and window burglar alarm unit can be roughly classified into a contact reed switch or an infrared sensor type alarm unit, etc. However, the aforementioned alarm unit has disadvantages in that:

1. The contact reed switch is easy to be detected: the contact reed switch is placed at the edge of the window or the door is easy to be detected, and is easily destroyed by a thief and loses its function.

2. Contact reed switch installation is limited: contact reed switch can be installed on the door and window, but it is difficult to be installed on the iron roll door, because the roll of the iron roll door easily breaks the contact reed switch .

3. Infrared sensor type malfunctions: Infrared sensor type alarm unit is prone to dead angles and many malfunctions. For example, when a cat or a dog passes by, the alarm unit is accidentally touched and a malfunction occurs.

4. Infrared inductive installation is limited: Due to the infrared inductive type of malfunction, the infrared sensor type alarm unit is mostly installed indoors. However, when the thief opens or destroys the entire door, the infrared-sensing alarm unit will not be activated, and will wait until the thief enters the room. It is impossible to warn when the thief is about to destroy, and the practicality is not good.

Therefore, how to solve the shortcomings and limitations of the prior art door and window burglar alarm unit that is easily detected and destroyed, limited in installation, and prone to malfunction, is an urgent need for the related industry.

A further technical means of the present invention is that the warning unit further includes a main switch electrically connected to the control mechanism, and a display lamp electrically connected to the control mechanism, when the main switch is activated, the speaker can be activated, and When the main switch is activated, the indicator light is a green light, and when the rolling element is in contact with the sensing element, the display light changes to a red light.

Another technical means of the present invention is that the sensing mechanism further includes a stopper disposed at the distal end for blocking the rolling member.

A further technical means of the present invention is that the outer casing unit comprises a rear casing and a front casing which are detachably coupled, the power supply of the warning unit, the control mechanism, and the speaker are disposed behind On the housing.

A further technical means of the present invention is that the front casing has a through slot and a transparent cover that blocks one side of the through slot, the accommodating space is formed by the rear casing, the through slot and the transparent The cover is made up together.

Another technical means of the present invention is that the door anti-theft device further includes a mobile unit, the action unit includes an application module, and the control mechanism has a communication module built therein, and the rolling member is in contact with the sensing member. When turned on, the communication module sends a signal to the application module.

Another technical means of the present invention is that the door anti-theft device further comprises a cover unit, comprising a covering sleeve for accommodating the outer casing unit, and a sheath extending upwardly and flexible Sexually used to cover the hanging sleeve on the door handle.

Still another technical means of the present invention is that the outer casing unit is directly embedded on the door handle.

The beneficial effects of the present invention are that, by the present invention, it is directly disposed on the door handle and is located in the house or in the room, which is difficult to be found and has high privacy and is not easily damaged.
