Reserved grooves are provided near the two ends of the inner wall of the circular groove, and the power supply line and screen cable pass through the corresponding reserved grooves respectively. Guide grooves are provided on the injection molded shell near both ends of the wiring groove, and a sleeve rod is sleeved in the guide groove. A pressure block is connected to the top end of the sleeve rod, and the bottom end of the pressure block is located on the upper side of the bottom of the wiring groove. A cylindrical spring is connected between the outer wall of the sleeve rod and the injection molded shell.

[0007] By adopting the above technical scheme, a rectangular groove is pre-opened on the external temperature and humidity sensor, and the injection molded shell is conveniently installed in the rectangular groove by installing bolts. A screen cable socket is set on the main board of the temperature and humidity sensor, and the temperature and humidity sensor has its own battery. A power supply socket is set on the battery, and the power supply plug is connected to the power supply socket, and the cable connector is connected to the cable socket, so as to realize power supply to the display screen and display the data monitored by the temperature and humidity sensor on the display screen. By moving the sleeve rod in the guide groove, the pressing block is conveniently lifted. At this time, the cylindrical spring is compressed, and after the power supply line or the screen cable passes through the lower end of the pressing block, the external force on the pressing block is stopped, and the cylindrical spring rebounds, driving the pressing block to press down, so that the power supply line or the screen cable can be pressed and fixed. Since the wiring grooves are set at the top, bottom and both ends of the circular grooves, it can be connected online from multiple directions, so that the display structure can be wired from multiple directions when the power supply line and the screen cable are wired, and the flexibility is good when the power supply line and the screen cable are installed.

[0008] Specifically, tapered grooves are provided on the edges of the injection-molded housing near the wiring grooves.

[0011] Specifically, strip-shaped protrusions are arranged on one side of the injection-molded housing near both ends of the corner protrusions.

[0012] By adopting the above technical solution, a step space can be formed on the back of the injection-molded housing through the corner protrusions and the strip-shaped protrusions, which is beneficial to the heat dissipation of the display screen.

[0013] Specifically, the injection-molded housing is provided with round chamfers near the corners.

[0014] Specifically, the injection-molded housing is made of POM material.
