Embodiment 1

[0027] The anti-theft alarm device of the present invention is composed of a housing 1, and the housing 1 accommodates: a reel 3 that winds the rope 2, a coil spring 4 that provides a winding force to the reel 3, and a coil spring 4 that is arranged around the reel 3 and passes through the rope. 2 is pulled out or pulled in by the coil spring 4 to make the reel 3 rotate, and the switch of the switch 5 is turned on the protruding mechanism 8, and the switch is connected by pulling out the rope 2 or pulled in by the coil spring. The alarm action switch 5 that is turned on when the switch 5 is pulled by the protrusion mechanism 8, the alarm sound generating device 16 that is operated by the switch 5, and the battery 6 that provides power to the alarm sound generating devices such as the alarm buzzer 16; The free end of the rope 2 has a fixing mechanism 7 which can be fixed on the window frame.

[0028] Since the rope 2 is colored in a conspicuous color such as red or yellow from ...

Embodiment 2

[0034] image 3 Shows examples of installation on various security objects, a shows the situation where the security alarm device is installed between bicycles and buildings such as fences, and b shows that the security alarm device is installed between a picture and a wall. The situation of the alarm device, c shows the situation that the anti-crime alarm device is set between the curtain or the door and the wall, d shows the situation that the anti-crime alarm device is set between the shutter and the window frame, e shows The case where the security alarm device is installed between the laundry and the pillars, etc. The anti-crime alarm device of the present invention is a very simple anti-crime alarm device with low price. It can be widely used on anti-crime objects such as pictures, bags, laundry, bicycles, etc., and can also be very easily installed on anti-crime objects. .

Embodiment 3

[0036] Figure 4 A state in which the casing 1 of the alarm device of the present invention is mounted on the mounting plate 18 is shown. The alarm device of the present invention is provided with an engaging slot 21 at the center of the back side of its housing 1, and the engaging slot 21 is engaged with the opening pin 19 arranged at the center of the mounting plate 18, thereby the device housing 1 is installed on the mounting plate 18, therefore, the device casing 1 can freely rotate around the pin shaft 19. In this way, because the device housing 1 is free to rotate around the pin shaft 19, the pull cord 2 for the reel action can be rotated corresponding to the pulling position of the person, and can be pulled out from the alarm device housing 1 in the vertical direction from time to time. . The mounting plate 18 is equipped with a double-sided adhesive tape 20 on its bottom surface, which can be installed at the position where it is desired to arrange the alarm device. ...

Abstract

A simple alarm device that can be simply and easily installed on various anti-crime objects, reduces manufacturing costs and installation costs, and can be used as an emergency calling mechanism. It consists of a reel containing a winding rope, a coil spring, a switch-on protruding mechanism that pulls the switch when the reel turns, an alarm action switch that is turned on when the switch is turned on when the switch is turned on by the protruding mechanism, an alarm sound generating device, and a battery. The free end of the rope has a fixing mechanism that can be fixed at a specified position. At the same time, it has a mounting mechanism for installing the device casing itself. There is an engaging slot in the center of the back of the device casing, so that the The engaging slot is engaged with the opening pin located in the center of the mounting plate to place the device housing on the mounting plate. Therefore, the device housing can rotate freely around the pin shaft. At the same time, the alarm device body can be assembled and disassembled. mounted on the mounting plate.

Description

technical field [0001] The present invention relates to a simple alarm device that can be easily installed on an opening and closing mechanism such as a security object or a window of a house, and more particularly relates to a simple security alarm device that detects movement of a security object or intrusion from a window of a house, etc. And how to use the simple alarm device. Background technique [0002] Currently, security systems for houses are widely used, and security sensors for windows that detect people entering a room through windows are used as the security systems for homes. As a conventional anti-theft sensor for a window, there is a switch detection type anti-theft sensor that combines a magnet with a magnetic wire switch that operates by approaching and separating from the magnet. When an intruder opens the window, the magnetic wire switch operates and outputs a detection signal. (For example, refer to Patent Document 1); In addition, there is such an arm...
