Problems solved by technology

The other is the integral design of the base and the cover. The cover of this sensor can be opened, but it cannot be removed and separated from the base. When installing, only the cover can be opened, and then the screw is screwed to fix the base on the wall. , there are disadvantages in the installation of these two structures. The first structure is cumbersome and time-consuming to install, and the second structure brings difficulties to installation when the installation space is small, or even cannot be installed.
[0005] 2. Traditional security sensors use containers (such as plastic bags, cartons, etc.) to store screws for installation. On the one hand, using containers will cause waste. On the other hand, installers may ignore the screws in the container and use other non- Special screws for installation, affect the use
[0006] 3. The installation method of the filter bracket is generally to put the filter bracket directly on the sensor element, which is relatively easy to shift or even fall off, and the function and performance of the sensor will be affected

Embodiment Construction

[0075] Please refer to Figure 1 to Figure 3 As shown, it shows the specific structure of the preferred embodiment of the present invention, it is a security sensor, its structure includes a base 1 and a cover 2, in the inner space formed by the base 1 and the cover 2 is installed Anti-insect sponge 3, circuit board 4, PD bracket 5, PD element 6, optical filter 7, PD anti-insect sponge 8. Lens 10 support 9 is installed on this face cover 2, and lens 10 is installed on the lens 10 support 9, also on the lens 10 support 9, freeze frame name plate 11 is installed. The bottom surface of the base 1 is pasted with an anti-counterfeiting label 12 and a CCC sticker 13, and is also provided with a screw 14 that can prevent opening the cover.

[0076] Among them, such as Figure 4 to Figure 12 As shown, a fastening mechanism 15 is provided between the base 1 and the cover 2. The fastening mechanism 15 is composed of an elastic button 151 and a buckle 152. The elastic button 151 is arr...

Abstract

The invention discloses a security sensor, which includes a base, a face cover, a circuit board, a PD element, an optical filter and a PD bracket. A shaft rotation mechanism is arranged between the base and the face cover, and the face cover and the face cover are connected by a rotating shaft structure. The base can not only be rotated together, but also can be separated, so as to realize the two installation methods of integrated installation and separate installation; there is also an anti-opening structure between the base and the cover to prevent non-professionals from opening the cover at will. Cover, touch the sensitive elements inside the sensor and affect the function; and, the welding legs of the PD element of the present invention are first passed through the through holes of the PD bracket and then welded to the circuit board. Once the welding legs are fixed with the circuit board, the PD bracket There is no risk of detachment and displacement.

Description

technical field [0001] The invention relates to the technology in the field of sensors, in particular to a security sensor. Background technique [0002] The sensors of the security system mainly include infrared alarm detectors, microwave detectors, vibration detectors, ultrasonic detectors, smoke detectors, etc. These detectors are installed on the wall or ceiling to ensure the safety of users. [0003] The structure of the security sensor generally includes a base and a cover, and a sensitive element and a circuit board are installed in the space formed between the base and the cover. However, due to the limitations of its structural design, traditional security sensors have the following defects: [0004] 1. There are generally two ways to assemble the base and the cover. One is the split design of the base and the cover. When this kind of sensor is installed on the wall or ceiling, it is generally necessary to remove the cover to make the base fit the wall. , and then...
