[0002] An infrared triggered alarm device is a device that uses infrared technology to realize automatic alarm. This device usually consists of an infrared transmitter and a receiver. It detects the existence of an object by measuring the heat emitted by the object. It uses infrared as a detection medium. When the infrared light emitted by the transmitter is blocked by an obstacle, the receiver cannot receive the infrared signal, thereby triggering an alarm. Once an object enters the infrared detection area, the device will trigger an alarm signal and alert personnel through sound.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figures 1 to 5 An infrared triggered alarm device comprises an alarm device body 1, an infrared transmitter 2 is embedded in the top of the front side of the alarm device body 1, an alarm speaker 3 is embedded in the bottom of the front side of the alarm device body 1, a closing cover 4 is slidably connected to the top of the front side of the alarm device body 1, an infrared receiver 5 is fixedly connected to one side of the closing cover 4, a push plate 6 is fixedly connected to the front side of the closing cover 4, a sliding groove 7 is provided on the inner side of the alarm device body 1, a convex column 8 is embedded in the interior of the closing cover 4, one side of the convex column 8 is opened, a first tension spring 9 is fixedly connected to the interior of the convex column 8, one end of the first tension spring 9 is fixedly connected to the inner wall of the sliding groove 7, and a clamping mechanism is slidably connected to the top of the front side of the alarm device body 1.

[0025] The clamping mechanism comprises a slide plate 101 . One side of the slide plate 101 penetrates into the interior of the alarm device body 1 . The end of the slide plate 101 located in the alarm device body 1 is fixedly connected to a support plate 102 .

[0026] Both sides of the bottom of the support plate 102 are fixedly connected with a clamping plate 103 , and a clamping slot 104 is provided on the top of the closing cover 4 , and the clamping plate 103 and the clamping slot 104 are clearance-matched.

[0027] A second tension spring 105 is fixedly connected to the bottom of the slide plate 101 , and one end of the second tension spring 105 is fixedly connected to the inner wall of the alarm device body 1 .

[0028] The working principle of this embodiment is as follows: when it is necessary to temporarily turn off the trigger of the alarm device body 1, the user pulls the two push plates 6 inwards, so that the two push plates 6 are close to each other and closed. When the two push plates 6 move, the two closing covers 4 are driven to approach each other and close. The closed closing covers 4 will push the card plate 103 upward along the slope of the card plate 103 during the movement, and after the card plate 103 enters the card slot 104, the closing cover 4 is clamped and limited by the card plate 103, so that the two closing covers 4 will not move away from each other and reset. By fixing the closed closing covers 4, the infrared receiver 5 on one side of the closing cover 4 can be opposite to the infrared transmitter 2. At this time, the infrared rays emitted by the alarm device body 1 are received normally, and there is no obstruction between the two. Therefore, when an object passes through one side of the alarm device body 1, the alarm will not be triggered. The infrared triggering function of the alarm device body 1 can be temporarily turned off. It is suitable for scenes such as multiple people or carrying items to prevent frequent false alarms and reduce the loss of the alarm device body 1.

[0029] When the two closed covers 4 need to be opened, the user pushes the slide plate 101 upwards, the slide plate 101 drives the support plate 102 to move upwards, and the support plate 102 drives the card plate 103 to move upwards, so that the card plate 103 leaves the card slot 104 at the top of the closed cover 4. At this time, the closed cover 4 opens and resets to both sides under the pulling force of the first tension spring 9, so that the alarm device body 1 can be used normally.
