Description

Technical Field

[0001] The utility model relates to the technical field of microwave inductor installation, and particularly relates to a microwave inductor with flexible installation. Background Technique

[0002] A microwave inductor is an instrument made using the Doppler principle of electromagnetic waves and is also known as a microwave radar. It detects the presence and motion state of an object by emitting high-frequency electromagnetic waves and receiving their reflected echoes. The working principle of the microwave inductor is based on the Doppler effect, that is, when microwaves encounter a moving object, scattering will occur on its surface, and part of the electromagnetic energy reaches the receiving antenna of the detector through the reflection on the surface of the moving object. After the receiving antenna receives the reflected microwave signal, it detects the electromagnetic parameters of the reflected wave through the signal processing circuit, thereby realizing the microwave induction function.

[0003] Microwave inductors have a variety of applications, including but not limited to bathrooms, underground garages, offices, classrooms, warehouses, corridors, and stairwells. They can detect whether the position of an object has moved in a non-contact manner and generate corresponding switching operations accordingly. Currently, microwave inductors on the market generally can only be installed by ceiling mounting or can only be installed by being equipped with an 86 box. That is, the same microwave inductor cannot accommodate multiple installation methods, reducing the usage scenarios of the microwave sensor and limiting the microwave inductor. Content of the Utility Model

[0004] The purpose of the utility model is to address the technical problems existing in the background technique and propose a microwave inductor with flexible installation, including an inductor body and a mounting bracket. The mounting bracket is detachably connected to the inductor body. An elastic mounting member is detachably provided on one end face of the mounting bracket for ceiling mounting of the mounting bracket. Mounting holes are also provided on the mounting bracket for fixed installation of the mounting bracket on the wall.

[0005] Further, the mounting bracket includes a mounting plate and a connecting portion. The mounting plate is detachably connected to the inductor body. The connecting portion protrudes on both sides of the mounting plate, and the elastic mounting member is detachably connected to the connecting portion.

[0006] Further, the connecting portion is provided with a first bending portion and a second bending portion. The elastic mounting member includes a torsion spring and a fixing member. One end of the torsion spring is respectively connected to the first bending portion and the second bending portion, and the other end is connected to the fixing member.

[0007] Further, the torsion spring can rotate up and down between a first position and a second position relative to the connecting portion. By overcoming the elastic potential energy of the torsion spring and applying an upward force to it, the torsion spring can be rotated from the first position to the second position. After removing the force, the torsion spring will rebound from the second position to the first position.

[0008] Further, a receiving groove is provided on the side of the sensor body that is connected to the mounting plate, and the receiving groove is used for receiving the connecting portion.

[0009] Further, the mounting bracket is magnetically connected to the sensor body.

[0010] Compared with the prior art, the present utility model has the following beneficial technical effects: Through the above settings, as an implementation manner of the present utility model, when installing the microwave sensor, an installation opening can be pre-opened on the ceiling, and then an upward acting force is applied to the elastic mounting member to make the elastic mounting member move upward so that the elastic mounting member penetrates into the installation opening. At this time, the acting force is removed, and the elastic mounting member rebounds to achieve the ceiling-mounted installation of the microwave sensor.

[0011] Further, as another implementation manner of the present utility model, when installing the microwave sensor, the elastic mounting member can be disassembled from the mounting bracket, and at the same time, the mounting bracket can be removed from the microwave sensor body. Fasteners, such as screws, etc., penetrate into the mounting holes and are fixedly connected to the wall or the 86 box to fix the mounting bracket on the wall or the 86 box, and then the microwave sensor body is connected to the mounting bracket to achieve the fixed installation of the sensor body.

[0020] The following will make a detailed description of the specific embodiments of the present utility model with reference to the drawings.

[0021] As Figures 1 - 4 shown, the present utility model provides a microwave sensor with flexible installation, which includes a sensor body 1 and an installation bracket 2. The installation bracket 2 is detachably connected to the sensor body 1, and the installation bracket 2 is used for the fixed installation of the sensor body 1. Specifically, in this embodiment, the installation bracket 2 is magnetically connected to the sensor body 1. The installation bracket 2 is provided with elastic installation members 21 in pairs on one end face. The elastic installation members 21 are detachably connected to the installation bracket 2 and can rotate up and down relative to the installation bracket 2. The installation bracket 2 is also provided with installation holes 22.

[0022] Through the above settings, as an implementation manner of the present utility model, when installing the microwave sensor, an installation opening 3 can be pre-opened on the ceiling, and then an upward acting force is applied to the elastic installation members 21 to make the elastic installation members 21 move upward so that the elastic installation members 21 penetrate into the installation opening 3. At this time, the acting force is removed, and the elastic installation members 21 rebound to achieve the ceiling-mounted installation of the microwave sensor.

[0023] Further, as another implementation manner of the present utility model, when the microwave inductor is installed, the elastic mounting member 21 can be disassembled from the mounting bracket 2, and at the same time, the mounting bracket 2 can be removed from the microwave inductor body 1. Fasteners, such as screws, are inserted into the mounting holes 22 and fixedly connected to the wall or the 86-box 4 to fix the mounting bracket 2 on the wall or the 86-box 4. Then, the microwave inductor body 1 is connected to the mounting bracket 2 to realize the fixed installation of the inductor body 1.

[0024] It can be understood that by providing the mounting bracket 2, the mounting bracket 2 is detachably connected to the microwave inductor body 1, and the elastic mounting member 21 is detachably provided on the mounting bracket 2 for the ceiling mounting of the microwave inductor body 1. Further, the mounting bracket 2 is also provided with mounting holes 22 for the fixed installation of the microwave inductor body 1 to the wall or the 86-box 4, realizing three installation manners of the microwave inductor, improving the installation flexibility of the microwave inductor, enabling the microwave inductor to adapt to different installation scenarios, with a simple structure and convenient installation.

[0025] Further, in this embodiment, the mounting bracket 2 includes a mounting plate 201 and a connecting portion 202. The mounting plate 201 is detachably connected to the inductor body 1. The connecting portion 202 protrudes from both sides of the mounting plate 201, and the elastic mounting member 21 is detachably connected to the connecting portion 202. Specifically, the connecting portion 202 is provided with a first bending portion 2021 and a second bending portion 2022.

One end of the torsion spring 211 is connected to the first bending portion 2021 and the second bending portion 2022 respectively through the opening, and the other end is connected to the fixing member 212.

[0026] With the above settings, the torsion spring 211 can rotate up and down between a first position and a second position relative to the connecting portion 202. Specifically, by overcoming the elastic potential energy of the torsion spring 211 and applying an upward force to the torsion spring 211, the torsion spring 211 can be rotated from the first position to the second position. After the force is removed, the torsion spring 211 will rebound from the second position to the first position.

[0027] Further, in this embodiment, the sensor body 1 is provided with a receiving groove 101 on the surface "connected to the mounting plate 201", and the receiving groove 101 is used for receiving the connecting portion 202. Through the above setting, when the present utility model is fixedly installed with a wall or an 86 box 4, the mounting plate 201 can be removed from the microwave sensor body 1, the mounting plate 201 is flipped, and the flat end surface of the mounting plate 201 is fixedly connected to the wall or the 86 box 4. Then, the end surface of the mounting plate 201 provided with the connecting portion 202 is magnetically connected to the microwave sensor body 1. It can be understood that when the mounting plate 201 is connected to the microwave sensor body 1, the connecting portion 202 will be inserted into the receiving groove 101 to achieve the flat installation of the microwave sensor body 1 with the wall or the 86 box 4.
