Description

Technical Field

[0001] The utility model relates to the field of temperature sensor protection, in particular to a temperature sensor protection structure. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. It can be divided into two categories: contact and non-contact. In the prior art, temperature sensors are mostly composed of a housing, a junction box, a wiring port, a mounting fixture, a metal probe, a thermistor, etc. During use, the temperature sensor needs to expose the metal probe, and then use the metal probe to monitor the temperature of an object or device. However, when the temperature sensor is not in use, the metal probe used for temperature measurement is not protected and is easily damaged by collision. It is easy to cause collision during transportation and storage, resulting in damage to the metal probe.

[0003] Therefore, it is necessary to invent a temperature sensor protection structure. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a temperature sensor protection structure, including a sensor body, a probe rod is installed at the lower end of the sensor body, a junction box is installed at the upper end of the sensor body, a bellows is fixedly installed at the lower end of the junction box, a protective tube is fixedly installed at the lower end of the bellows, the bellows and the protective tube are located outside the sensor body and the probe rod, and a protective cover is installed at the lower end of the protective tube.

[0006] Based on the above features: when the temperature sensor needs to be used, the protective cover at the lower end of the protective tube can be unscrewed, and then the protective cover can be screwed on the upper end of the junction box. This can not only protect the surface of the junction box, but also prevent the protective cover from being lost due to being placed randomly. At this time, the protective tube can be pulled upward. At this time, the probe rod at the lower end of the sensor body will be exposed. When it is not needed, the bellows can be pulled to unfold and the protective tube can be moved downward. At this time, the probe rod will be protected between the bellows and the protective tube. Then unscrew the protective cover on the junction box, and then install the protective cover on the lower end of the protective tube, which is convenient for dust and bump protection of the sensor body and the probe rod.

[0007] Preferably, an anti-dropping sliding block is fixedly mounted on the outer wall of the lower end of the sensor body, a damping shaft in a ring array is mounted on the bottom of the sensor body, and a limit baffle is mounted on the damping shaft.

[0008] Based on the above features: when the bellows and the protective tube are pulled up and located outside the sensor body, the limit baffle can be rotated to protrude outward, and the limit baffle can be rotated through the damping shaft to facilitate the limit baffle to limit the protective tube and prevent the bellows and the protective tube from automatically moving downward.

[0009] Preferably, a display screen and a connection seat are provided at the upper end of the junction box, the display screen is located in the middle of the connection seat, and a wiring port is installed on one side of the junction box.

[0010] Based on the above features: the connection base is convenient for connection with the protective cover, the display screen can display the value of the monitored temperature, and the wiring port is convenient for connection of the power cord with the wiring box.

[0011] Preferably, the connecting seat is a hollow cylindrical structure, and a thread is provided on the surface of the connecting seat.

[0012] Based on the above features: the protective cover and the connecting seat are threadedly connected, and since the connecting seat is hollow, personnel can check the temperature value on the display screen in the middle of the connecting seat.

[0013] Preferably, a guide groove is provided on the inner wall of the protection tube, and a thread is provided on the lower end surface of the protection tube.

[0014] Based on the above features: the anti-detachment sliding block is slidably connected to the guide sliding groove, so that the protective cover will not rotate or detach outside the sensor body.

[0015] Preferably, the corrugated tube and the protective tube are hollow cylindrical structures with openings at both ends.

[0016] Based on the above characteristics: the bellows and the protective tube can be telescopically adjusted outside the sensor body and the probe rod, and the bellows and the protective tube can wrap the sensor body and the probe rod inside for protection.

[0017] Preferably, transparent glass is installed in the middle of the protective cover, and an inner thread is provided on the inner wall of the protective cover.

[0018] Based on the above features: when the protective cover is threadedly connected to the connecting seat, the transparent glass on the surface of the protective cover will be aligned with the display screen, making it convenient for personnel to observe the display screen through the transparent glass, and due to the protection of the protective cover and the transparent glass, external dust and oil will not adhere to the display screen.

[0019] The beneficial effects of the utility model are:

[0020] 1. The temperature sensor can be protected. When the temperature sensor needs to be used, the protective cover at the lower end of the protective tube can be unscrewed, and then the protective cover can be screwed on the upper end of the junction box. This can not only protect the surface of the junction box, but also prevent the protective cover from being lost due to random placement. At this time, the protective tube can be pulled upward to expose the probe rod. When it is not needed, the bellows can be pulled to expand and the protective tube can be moved downward. At this time, the probe rod will be protected between the bellows and the protective tube. Then unscrew the protective cover on the junction box, and then install the protective cover on the lower end of the protective tube. This is convenient for dust and bump protection of the sensor body and the probe rod.

[0021] 2. The anti-detachment slider is slidably connected to the guide slide groove so that the protective cover will not rotate or detach outside the sensor body. When the bellows and the protective tube are pulled up and located outside the sensor body, the limit baffle can be rotated to protrude outward. The limit baffle can be rotated through the damping shaft to facilitate the limit baffle to limit the protective tube and prevent the bellows and the protective tube from automatically moving downward. When the bellows and the protective tube need to be pulled down, the limit baffle can be pushed back to the end face of the sensor body. At this time, the limit baffle will not hinder the bellows and the protective tube from moving downward. BRIEF DESCRIPTION OF THE DRAWINGS
