Description

Technical Field

[0001] The present application relates to the technical field of detectors, and specifically discloses an infrared detector. Background Art

[0002] The human body has a constant body temperature, generally around 37 degrees, and emits infrared rays with a specific wavelength of about 10um. Passive infrared detectors work by detecting infrared rays of about 10μm emitted by the human body. The infrared rays of about 10um emitted by the human body are enhanced by the Fresnel filter and then gathered on the infrared sensing source. The infrared sensing source usually uses a pyroelectric element. When this element receives the temperature change of the human body's infrared radiation, it will lose its charge balance and release the charge outward. The subsequent circuit can generate an alarm signal after detection and processing;

[0003] Advantages: It does not emit any type of radiation, the device consumes very little power, has good concealment, and is inexpensive. Disadvantages: It is easily interfered by various heat sources and sunlight sources: Passive infrared has poor penetration, the infrared radiation of the human body is easily blocked and not easily received by the detector: It is easily interfered by radio frequency radiation; when the ambient temperature is close to the human body temperature, the detection and sensitivity are significantly reduced, sometimes causing short-term failure.

[0004] How to correctly install and use passive infrared detectors:

[0005] Passive infrared detectors are a type of detector that is very commonly used in security projects. However, to use them normally, it is necessary to prevent missed alarms and reduce false alarms, mainly to minimize false alarms. To do this, you must first understand some basic concepts and technical characteristics of passive infrared detectors, so that you can use them according to these basic technical characteristics, from installation, debugging, use and other aspects, in accordance with the basic technical characteristics of the detector, so that you can maximize the effectiveness of the detector;

[0006] As we all know, the installation height of the detector is not random, it will directly affect the sensitivity of the detector and the effect of preventing small animals. Generally, the installation height of wall-mounted infrared detectors is 2.0-2.2 meters.

[0007] However, at present, not all installation locations of the wall-mounted infrared detectors are flat surfaces. Therefore, the wall-mounted infrared detectors are sometimes difficult to install. In view of this, the inventor proposes an infrared detector. Utility Model Content

[0016] Furthermore, a curved groove is formed on a side of the mounting bracket away from the wall-mounted infrared detector body.

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] The figure marks in the drawings of the specification include: mounting plate 1, wall-mounted infrared detector main part 2, connecting hole 3, connecting rod 4, mounting frame 5, arc groove 6, groove 7, first strap 8, buckle 9, second strap 10, slot 11, mounting block 12, mounting slot 13, double-sided tape 14.

[0029] Implementation example Figure 1 , Figure 2 and Figure 3 As shown:

[0030] An infrared detector comprises a wall-mounted infrared detector body and an upper wall assembly detachably connected to the wall-mounted infrared detector body;

[0031] Regarding the wall-mounted infrared detector body, the traditional wall-mounted infrared detector body includes a wall-mounted infrared detector main part 2 and a mounting plate 1 fixedly connected to the wall-mounted infrared detector main part 2. The mounting plate 1 is used to realize the upper wall, but this upper wall is only applicable to a plane upper wall, that is, it is more suitable for household use, and is not applicable to outdoor tree stumps and outdoor street lamp upper walls;

[0032] Therefore, this case makes improvements on this basis:

[0033] The upper wall assembly includes a mounting frame 5 for the upper wall, a groove 7 opened on the mounting frame 5 for connecting with the wall-mounted infrared detector body, and a strap assembly arranged at both ends of the mounting frame 5;

[0034] A double-sided adhesive tape 14 is disposed at one end of the mounting frame 5 away from the wall-mounted infrared detector body.

[0035] Specifically: the mounting plate 1 is provided with connecting holes 3 around it, each of which is connected with a connecting rod 4 inserted therein, the other end of the connecting rod 4 being inserted into a groove 7, the end surface of the groove 7 being provided with a connecting bolt, the connecting bolt being inserted into the groove 7 and connected with the connecting rod 4.

[0036] Specifically: this step is equivalent to using the mounting bracket 5 on the wall. As long as the mounting bracket 5 can be mounted on the wall, there will be no problem with the upper wall of the entire device. Regarding the upper wall of the mounting bracket 5, an arc groove 6 is opened on one side of the mounting bracket 5 away from the wall-mounted infrared detector body.

[0037] A strap assembly is designed for outdoor tree stumps and the upper wall of outdoor street lamps. The strap assembly includes a first elastic strap and a second elastic strap. A buckle 9 is provided at the end of the first elastic strap, and a plurality of slots 11 are provided on the second elastic strap. The buckle 9 and the slots 11 are detachably connected.

[0038] Through the detachable connection between the buckle 9 and the slot 11, the device can be bundled with outdoor tree stumps and outdoor street lamps, and then the upper wall is bundled. Due to the use of the upper wall bundling, the effect of the double-sided tape 14 is weak at this time. Therefore, an arc groove 6 is opened on the inner side of the wall-mounted infrared detector body to make the device as close to the outdoor tree stumps and the outdoor street lamps as possible. Then, in order to improve the installation stability, a mounting block 12 is provided on the back of the wall-mounted infrared detector main part 2, and a mounting groove 13 is opened in the mounting block 12. A telescopic rod is threadedly connected to the mounting groove 13, and the free end of the telescopic rod is provided with an adhesive surface, and the size of the adhesive surface is larger than the end surface size of the free end of the telescopic rod.

[0039] like Figure 3 As shown, a telescopic rod is installed in the installation groove 13, and the adhesive surface is used to press against a tree stump and a street lamp in the wild to cooperate with the binding belt assembly to improve the installation stability of the device.

[0040] The device solves the problem that traditional wall-mounted infrared detectors are not easy to mount on the wall.
