Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically a remote dust particle sensor. Background Technology

[0002] A remote dust particle sensor is an advanced detection device. It is primarily used to accurately measure parameters such as the quantity and size of dust particles in the environment. Its working principle is based on technologies such as optical scattering. When dust particles enter the sensor's detection area, light is scattered, and the sensor determines the particle's characteristics by capturing and analyzing the scattered light signal. This sensor has the advantage of remote monitoring, enabling real-time sensing of dust conditions in a target area from a certain distance. This plays a crucial role in many scenarios, such as in cleanrooms where it can monitor air quality in a timely manner to ensure the cleanliness of the production environment meets requirements; and in special locations such as hospital operating rooms where it can monitor dust particle conditions at any time to ensure medical safety. Furthermore, its monitoring data can provide strong evidence for environmental governance and air purification, contributing to the creation of a healthy and high-quality environment. According to the utility model patent with patent authorization announcement number CN209624295U, a dust particle detector is composed of a particle measuring instrument and a support. The support includes a frame and a frame plate. The frame plate is composed of a lifting plate and a fixed plate. The particle measuring instrument is fixed to the lifting plate of the frame plate. A carrier plate is provided on the frame, and a lifter is provided on the carrier plate. The lifting column of the lifter passes through the fixed plate and is connected to the lifting plate. A lifting controller is provided outside the lifter. An infrared sensor, a lifting controller, and a battery box are provided inside the lifting controller.

[0003] However, the mounting brackets for remote dust particle sensors have certain limitations in practical applications. Current bracket designs lack adjustability, making it impossible to flexibly adjust the sensor's position and angle according to the specific placement environment and actual needs. When placed on planes of different shapes, angles, or heights, the inability of the bracket to adapt can easily lead to instability, potentially affecting the sensor's normal operation and causing deviations in measurement data. Utility Model Content

[0004] The purpose of this invention is to provide a remote dust particle sensor that solves the problem that the support of the remote dust particle sensor is not adjustable and is prone to instability when placed.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model is meticulously designed, with key components such as a threaded rod, a limiting sleeve, and a guide rod working in tandem. When the limiting sleeve is rotated, it generates precise threaded movement with the threaded rod, thereby driving the support base to move flexibly. This allows for convenient and quick adjustment of the support base position, enabling timely adjustments to the base support point, effectively solving the problems of non-adjustable and unstable placement of remote dust particle sensor brackets, and ensuring stable sensor placement.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A remote dust particle sensor includes a base 1, a main body 11 fixedly connected to the upper end of the base 1, a threaded rod 2 slidably connected inside the base 1, a support base 21 fixedly connected to the lower end of the threaded rod 2, a guide rod 22 fixedly connected to the outer side of the support base 21, the guide rod 22 contacting the base 1, and a guide block 23 fixedly connected to the outer side of the base 1. The guide rod 22 and the guide block 23 are slidably connected. The design of the guide block 23 can limit the movement of the guide rod 22.

[0021] Please see Figure 2-4The base 1 has a rotatable limit block 24 inside, which is movably connected to the threaded rod 2. The limit block 24 has a fixed protrusion 25 on its outer side, which is rotatably connected to the base 1. The protrusion 25 can limit the limit block 24 through its design. The lower end of the limit block 24 is fixedly connected to a limit sleeve 26, which contacts the support base 21 and the base 1. The limit sleeve 26 is threadedly connected to the threaded rod 2. The position of the support base 21 can be adjusted through the design of the limit sleeve 26. The base 1 is provided with a limit mechanism 3.

[0022] Please see Figure 2-4 The limiting mechanism 3 includes a limiting frame 31. The lower end of the base 1 contacts the limiting frame 31. The limiting sleeve 26 has a slot 32 inside. The limiting frame 31 contacts the limiting sleeve 26 and is slidably connected to the slot 32. Through the design of the limiting mechanism 3, the limiting sleeve 26 can be limited. The upper end of the limiting frame 31 is fixedly connected to a slider 33. The outer side of the slider 33 is fixedly connected to a sliding rod 34. The slider 33 is slidably connected to the base 1, and the sliding rod 34 is slidably connected to the base 1. A spring 35 is provided on the outer side of the sliding rod 34. One end of the spring 35 contacts the slider 33, and the other end of the spring 35 contacts the base 1. Through the design of the limiting mechanism 3, the support base 21 can remain stable after adjustment.

[0023] The specific implementation process of this utility model is as follows: When in use, by moving the limiting frame 31 away from the limiting sleeve 26, the limiting frame 31 drives the slider 33 to move, the slider 33 drives the slide rod 34 to move, the slider 33 squeezes the spring 35, and the limiting frame 31 slides out of the slot 32 on the limiting sleeve 26, thus releasing the limitation on the limiting sleeve 26.

[0024] By rotating the limiting sleeve 26, the limiting sleeve 26 and the threaded rod 2 will undergo threaded movement, thereby causing the threaded rod 2 to drive the support base 21 to move. The support base 21 will then drive the guide rod 22 to slide on the guide block 23, which will keep the support base 21 stable when it moves. This allows the support point of the base 1 to be adjusted, thus keeping the main body 11 stable during use.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
