Description

Technical Field

[0001] The utility model belongs to the technical field of temperature sensors, and in particular relates to a temperature sensor with a waterproof plug-in structure. Background Art

[0002] The temperature sensor with waterproof plug-in structure is a temperature detection element with waterproof function. It usually consists of two parts: temperature sensitive element and waterproof plug-in structure. The temperature sensitive element is usually made of materials such as thermistor and thermocouple, which can sense the change of ambient temperature. The waterproof plug-in structure is to protect the temperature sensitive element from water or moisture erosion.

[0003] At present, many plug-in temperature sensors are used in pipelines to monitor the temperature of the liquid in the pipeline in real time. Generally, there are installation pipes or reserved holes for installing temperature sensors on the pipelines to facilitate the subsequent installation and maintenance of sensors.

[0004] However, most of the existing temperature sensors and pipelines are connected by plug-in connection and sealed with threads. Although the assembly effect can be achieved, if the precision between the threads is not enough during processing, gaps will be generated, affecting the sealing between the sensor and the pipeline. Water or liquid in the pipeline is easy to seep out, affecting the performance of the sensor. The temperature sensor cannot be sealed conveniently, increasing the risk of short service life or damage of the sensor due to water leakage and corrosion in the later stage.

[0005] Therefore, a new type of postoperative decompression pillow for posterior fossa surgery is designed to change the above technical defects. Utility Model Content

DETAILED DESCRIPTION

[0025] This specific embodiment is a temperature sensor with a waterproof plug-in structure, and its structural diagram is as follows Figure 1-Figure 6 As shown, it includes a sensor body 1 and a pipe 2, an external thread 3 is opened on the side wall of the sensor body 1, and an internal thread 4 is opened on the inner wall of the pipe 2, the external thread 3 is adapted to the internal thread 4, and a plurality of sealing gaskets 5 are fixedly connected to the side wall of the sensor body 1 on the upper side of the external thread 3, a sealing sleeve 6 is sleeved on the side wall of the pipe 2, and the end face of the sealing sleeve 6 is abutted against the sealing gasket 5, and a connecting component is arranged between the pipe 2 and the sealing sleeve 6.

[0026] like Figure 3 and Figure 4 As shown, the connection assembly includes a connection block 7 evenly fixedly connected to the inner wall of the sealing sleeve 6, a positioning groove 8 is evenly opened on the top end surface of the pipeline 2, a clamping groove 9 is opened on the side wall of the positioning groove 8, and the connection block 7 is movably connected to the clamping groove 9.

[0027] The cross section of the connecting block 7 is T-shaped, and the connecting block 7 is matched with the slot 9 .

[0028] Specifically, the use of a connecting assembly can facilitate the convenient fixing of the sealing sleeve 6 on the pipeline 2, and the number of the clamping grooves 9 is several, and the squeezing force on the sealing gasket 5 can be selected according to the actual sealing requirements.

[0029] like Figure 2 and Figure 6 As shown, a plurality of through holes 11 are provided on the end face of the sealing sleeve 6 , an annular groove 10 is provided inside the side wall of the sealing sleeve 6 , the through holes 11 are connected to the annular groove 10 , an annular shell 12 is fixedly connected to the top end face of the sealing sleeve 6 , and the annular shell 12 is connected to the annular groove 10 .

[0030] Specifically, during the use of the sensor body 1, if a poor seal occurs at the connection between the sensor body 1 and the pipe 2, causing leakage, the water flow in the pipe 2 can enter the annular groove 10 through the through hole 11 and appear inside the annular shell 12, making it convenient for the staff to observe the sealing condition of the sensor body 1 from the outside and perform maintenance in time.

[0031] like Figure 6 As shown, the cross section of the sealing gasket 5 is trapezoidal, and the sealing gaskets 5 are distributed in a ring array.

[0032] Specifically, there are tiny gaps between the sealing gaskets 5. When the sealing sleeve 6 is pressed downward, the sealing gaskets 5 are deformed downward by force, so that the sealing gaskets 5 are squeezed against each other to close the gaps, thereby facilitating sealing of a circle.

[0033] like Figure 3 and Figure 4 As shown, the top end surface of the pipeline 2 is fixedly connected to a limit plate 13, and the limit plate 13 is arranged in a ring shape.

[0034] Specifically, by setting the limiting plate 13, on the one hand, it is convenient to limit the sealing gasket 5 to prevent the sealing gasket 5 from deforming too much after being subjected to the pressure of the sealing sleeve 6, thereby affecting its sealing performance; on the other hand, it can limit the sealing sleeve 6 to achieve the effect of re-sealing.

[0035] Working principle: When installing the sensor body 1 on the pipe 2, first use the external thread 3 on the sensor body 1 to tighten the internal thread 4 of the pipe 2 to perform initial installation and sealing on the sensor body 1. When the sensor body 1 is tightened, the sealing gasket 5 fits on the end face of the pipe 2, and then press the sealing sleeve 6 down to make the connecting block 7 enter the positioning groove 8. When the end face of the sealing sleeve 6 presses the sealing gasket 5, the rotating sealing sleeve 6 drives the connecting block 7 to enter the card groove 9, which is used for secondary sealing between the sensor body 1 and the pipe 2, ensuring the stability of the sensor body 1 during use, avoiding leakage problems, and effectively extending the service life of the sensor body 1.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
