Description

Technical Field

[0001] This utility model belongs to the field of temperature sensor technology, and in particular relates to a temperature sensor with a fixed protective structure. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety of types. Based on the measurement method, they can be divided into two main categories: contact and non-contact sensors. According to the characteristics of the sensor materials and electronic components, they can be divided into two categories: resistance temperature detectors (RTDs) and thermocouples.

[0003] Temperature sensors are often used to monitor the temperature of goods during cold chain transportation. Temperature sensors are usually placed on the top of refrigerated boxes, but when more accurate monitoring of the temperature of specific goods is required, they are placed inside the goods. Traditional temperature sensors do not have a fixed protective structure, and they may be damaged by squeezing during transportation, which may affect the monitoring effect. They may also be damaged by bumps and movement, which may affect the monitoring effect. Utility Model Content

[0004] The purpose of this invention is to provide a temperature sensor with a fixed protective structure in order to solve the problem that traditional temperature sensors do not have a fixed protective structure.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: It includes a housing, a placement groove on the side of the housing, ventilation grooves penetrating both sides of the housing, a filter screen movably connected to the outlet of the placement groove, a limiting plate on the filter screen, a movable groove penetrating the top of the housing near the filter screen, a fixed groove at the bottom of the placement groove near the filter screen, a fixed block at the bottom of the placement groove, a movable groove on the side of the fixed block, an adjustment groove on the upper surface of the fixed block, a temperature sensor movably connected to the middle of the adjustment groove, clamping plates movably connected to both sides of the temperature sensor, a movable plate at the end of the clamping plates near the movable groove, a circular groove penetrating the side of the movable plate, a nut on the side of the circular groove away from the temperature sensor, a connecting plate on the side of the fixed block near the filter screen, a threaded post on the side of the connecting plate near the movable groove, a top plate movably connected above the temperature sensor, two springs symmetrically arranged above the top plate, and two fixing holes penetrating the housing on the side away from the filter screen.

[0006] Furthermore, the movable groove is located directly above the fixed groove and the two have the same length and width. The movable groove and the placement groove are connected through each other. The limiting plate is movably connected above the movable groove. The fixed groove is located on the side of the fixed block near the filter screen.

[0007] Furthermore, the filter screen is movably connected inside the movable groove and the fixed groove, the size of the filter screen matches the movable groove and the fixed groove, and the sum of the heights of the placement groove, the movable groove, and the fixed groove is the same as the height of the filter screen.

[0008] Furthermore, the movable groove and the adjusting groove are connected through each other, the clamping plate is movably connected inside the adjusting groove, the movable plate is movably connected inside the movable groove, and the end of the movable plate away from the clamping plate is located on the side of the movable groove.

[0009] Furthermore, the threaded post is movably connected to the inside of the circular groove and the nut, the threaded post is sized to match the circular groove and the nut, and the threads of the threaded post and the nut are in harmony.

[0010] Furthermore, the connecting plate is located on the side of the movable groove, the connecting plate is located between the fixed block and the fixed groove, and the length of the threaded column is greater than the length of the movable groove.

[0011] Furthermore, the top of the spring is fixedly connected to the top of the placement slot.

[0012] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0013] The housing is fixed in place using screws and mounting holes. The top plate is then moved upwards, and the temperature sensor is placed inside the adjustment slot. The top plate, held in place by springs, is then secured to the top of the temperature sensor. The clamping plates are moved to both sides of the temperature sensor, and the nuts are rotated to engage with the threaded posts, moving to both sides of the moving plate and fixing it in place. This fixes the position of the clamping plates and limits the position of the temperature sensor. The filter is then inserted into the moving slot and moved downwards until its lower end is inside the fixing slot, sealing the sides of the slot. This prevents the temperature sensor from being squeezed during use, ensuring accurate monitoring, and also prevents damage from vibrations. Furthermore, it facilitates installation and removal of the temperature sensor and allows for the use of different temperature sensors, expanding its applicability. Attached Figure Description
