Description

Technical Field

[0001] The present application relates to the technical field of detector positioning devices, and specifically discloses a detector positioning device. Background Art

[0002] The human body has a constant body temperature, generally around 37 degrees, and emits infrared rays of a specific wavelength of about 10 μm. Passive infrared detectors work by detecting infrared rays of about 10 μm emitted by the human body. The infrared rays of about 10 μm 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 wall-mounted infrared detectors are flat surfaces. Therefore, wall-mounted infrared detectors are sometimes difficult to install. In view of this, the inventors have invented a detector positioning device. Utility Model Content

[0008] The utility model aims to solve the problem that the traditional wall-mounted infrared detector lacks a locator and thus cannot be applied to all wall-mounted environments.

[0009] In order to achieve the above object, the utility model provides the following basic solutions:

[0010] A detector positioning device also includes a positioning component detachably connected to the detector body;

[0011] The positioning component comprises a mounting bracket with a symmetrical and adjustable relative distance, an elastic plate fixed to both ends of the mounting bracket, an adjusting piece arranged between the mounting brackets and a mounting hole opened on the adjusting piece.

[0012] The principles and effects of this basic solution are:

[0013] 1. Compared with the prior art, the present device has a simple structure and an ingenious design. The core of the present device is the design of a positioning component, which can be effectively installed based on a traditional wall-mounted infrared detector. Regardless of the external wall-mounted environment, the present device can be effectively and conveniently installed, solving the problem that traditional wall-mounted infrared detectors lack a locator and are therefore not suitable for all wall-mounted environments.

[0014] 2. Compared with the prior art, the core of this device is to use the positioning component to preferentially connect with the wall-mounted environment. The positioning component can avoid most wall-mounted environments, and then use the positioning component and the detector body for installation. When the positioning component and the detector body are installed, there is no need to consider the wall-mounted environment. This device is equivalent to providing a bridge between the wall-mounted environment and the wall-mounted infrared detector. The bridge is the positioning component. The positioning component solves the problem that the traditional wall-mounted infrared detector lacks a locator and cannot be applied to all wall-mounted environments.

[0018] Furthermore, the screw is arranged on the connection block, and the screw is a countersunk screw.

[0019] Furthermore, a fixing hole is provided at the free end of the elastic plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.

[0024] The reference numerals in the drawings of the specification include: detector body 1, connecting hole 2, connecting bolt 3, mounting bracket 4, mounting groove 5, elastic plate 6, fixing hole 7, mounting plate 8, plug plate 9, screw 10, connecting block 11, mounting hole 12, level 13.

[0025] Implementation example Figure 1 and Figure 2 As shown:

[0026] A detector positioning device also includes a positioning component detachably connected to the detector body 1;

[0027] The positioning assembly includes mounting brackets 4 with symmetrical and adjustable relative distances, elastic plates 6 fixed to both ends of the mounting brackets 4, adjusting members arranged between the mounting brackets 4, and mounting holes 12 opened on the adjusting members.

[0028] Regarding the detector body 1, the detector body 1 is a traditional wall-mounted detector. Specifically, the detector body 1 includes a detector main part, a battery pack built in the detector main part, and a mounting plate 8 fixedly connected to the detector main part.

[0029] The requirements for the wall-mounting environment of the mounting plate 8 are relatively high, and the wall-mounting environment needs to be sufficiently flat. Once the wall-mounting environment is not flat, there is a problem of difficulty in installing the detector body 1;

[0030] Based on this problem, a positioning component is designed in this case, and a mounting groove 5 is provided in the mounting bracket 4, a connecting bolt 3 is installed in the mounting groove 5, and a connecting hole 2 is provided on the mounting plate 8. One end of the connecting bolt 3 is connected to the mounting groove 5, and the other end of the connecting bolt 3 is connected to the connecting hole 2 on the mounting plate 8.

[0031] Specifically: the mounting bracket 4 and the mounting plate 8 are connected by the connecting bolts 3. The connection between the two is very simple. The connecting bolts 3 and the matching nuts are used to connect the two.

[0032] At this time, you only need to consider the installation of the mounting bracket 4 and the wall-mounted environment;

[0033] The adjusting member includes a connecting block 11, slots opened at both ends of the connecting block 11, a plug plate 9 slidably connected to the slots, a screw 10 for limiting the plug plate 9, and a level 13 arranged on the connecting block 11, and a mounting hole 12 is opened on the connecting block 11;

[0034] Specifically: the mounting hole 12 is driven into the fixing nail and the wall-mounted environment. At this time, no matter whether the wall-mounted environment is flat or curved, as long as there is a fixing nail, the connecting block 11 can be effectively installed. Then, after the connecting block 11 is installed, the position of the plug plate 9 is adjusted based on the size of the mounting plate 8, because the plug plate 9 can adjust the distance between the mounting brackets 4. When the distance of the plug plate 9 is adjusted, the screw 10 used to limit the plug plate 9 is used. The screw 10 is set on the connecting block 11, and the screw 10 is a countersunk screw 10. Limit the relative distance between the plug plate 9 and the slot;

[0035] Then check the level 13 to ensure the flatness of the entire device, and then install the detector body 1.

[0036] Since the entire device is connected by fixing nails, there may be instability. Based on this, a fixing hole 7 is provided at the free end of the elastic plate 6;

[0037] The elastic plate 6 is not only applicable to flat surfaces, but also can be used to fix the fixing holes 7 by using a curved surface such as a stump or a column, and the elastic plate 6 can be used in conjunction with fixing nails to enhance the installation stability of the device.

[0038] The device solves the problem that the traditional wall-mounted infrared detector lacks a locator and thus cannot be applied to all wall-mounted environments.
