Description

Technical Field

[0001] The utility model belongs to the technical field of temperature sensors, and in particular relates to a temperature sensor that is easy to seal and assemble. Background Art

[0002] A temperature sensor specifically refers to a type of sensor that can sense the temperature of the external environment and convert it into an output signal. The sensor itself needs to be close to the object being measured to obtain actual measurement data. Therefore, in actual measurement, the sensor needs to be installed and fixed on the surface of the object being measured, and the temperature sensor needs to have good sealing to avoid interference from external factors.

[0003] Chinese patent CN218724800U discloses a temperature sensor that is easy to assemble, which belongs to the technical field of temperature sensors. The temperature sensor that is easy to assemble includes a temperature sensor body and a housing. A sealing cover is provided just above the housing, and an assembly component A is installed between the housing and the sealing cover. The assembly component A includes a fixing seat, a positioning block, a fixing rod, a locking block, a pull rod, a pull plate and a spring A. The four corners of the housing surface are provided with mounting grooves, the fixing seat is fixed inside the mounting groove, and the fixing seat is provided inside an assembly The bottom of the sealing cover plate is provided with the positioning block at the position corresponding to the assembly groove, and the top of the positioning block is connected to the sealing cover plate through the fixing rod. A clearance groove is provided inside the fixing seat, and the surface of the locking block is slidably connected in the clearance groove. The pull rod is fixed on one side of the locking block, and the other end of the pull rod passes through the inner wall of the fixing seat and extends to the surface of the fixing seat and is connected to the pull plate located on one side of the fixing seat. The spring A is wound around the surface of the pull rod, and both ends of the spring A are fixed between the locking block and the clearance groove.

[0004] The assembly process of fixing with bolts is relatively cumbersome. Once the bolts are screwed out, they will become unusable and need to be reassembled, which leads to very low assembly efficiency. In the above document, by setting up the assembly component B, as the temperature sensor body continues to move downward, the locking between the card block and the card slot can be completed, thereby fixing the temperature sensor body and the fixed frame, but the sealing cover and the outer shell are only clamped by the positioning block and the locking block. If the pull rod is accidentally touched and the locking block is moved, the sealing between the sealing cover and the outer shell will be reduced.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

At the same time, the third stud 603 rotates synchronously with the second stud 601, so that the third stud 603 can be threadedly connected to the third screw hole 604 on the top cover 7.

[0040] The second screw bolt 601 and the second screw hole 602 have opposite rotation directions to the first screw bolt 405 and the first screw hole 5 .

The card block 804 pushes the limiting square plate 803 to compress the spring 802 until the card block 804 is completely aligned with the card slot 805. The spring 802 pushes the limiting square plate 803 and the card block 804 to reset, so that the card block 804 and the card slot 805 are plugged into each other to complete the preliminary fixation between the top cover 7 and the outer shell 1.

[0043] In one embodiment, the reset assembly 9 includes a sliding rod 901 , a push block 902 is fixedly connected to the outer surface of the sliding rod 901 , and the sliding rod 901 is slidably connected to the inside of the slot 805 .
