[0029] See also Figure 1-5 The utility model provides a technical solution: an installation structure for preventing overheating of a circuit radio frequency power amplifier module, including a body 1, a shell 2, a heat sensor 3, a motor 4, a bevel gear 5, a screw 6, a moving plate 7, a coolant pipe 8, a bag 9, a pressure ring 10, a threaded rod 11, a push plate 12, an air bag 13, a main gear 14, an air pipe 15, a tooth plate 16, and a push rod 17.

[0030] Example 1

[0031] The anti-overheating installation structure of the RF power amplifier module of the circuit is provided with an anti-overheating structure, which can quickly fill the coolant pipe 8 with coolant to cool down the temperature while the moving plate 7 rises, specifically:

[0032] The body 1 is embedded in the upper surface of the shell 2, and also includes a heat sensor 3, which is fixedly installed on the inner wall surface of the shell 2. The shell 2 is connected to an anti-overheating structure, which includes a motor 4. The motor 4 is installed in the front and rear inner wall slots of the shell 2, and the front end of the motor 4 is fixedly connected to a bevel gear 5, and another bevel gear 5 is meshed and connected below the bevel gear 5. The bevel gear 5 is fixedly installed on the outer surface of a screw rod 6, and the screw rod 6 is rotatably installed on the bottom surface of the inner wall of the shell 2. The outer surface of the screw rod 6 is rotatably connected to the outer surface protrusion of the moving plate 7. The anti-overheating structure also includes a coolant pipe 8, and the upper surface fixed pipe of the moving plate 7 is connected to the coolant pipe 8, and the openings at both ends of the coolant pipe 8 are connected through a sac 9, which is fixedly installed on the upper surface of the side wall interlayer of the shell 2, and the lower part of the sac 9 corresponds to the side surface protrusion of the moving plate 7;

[0033] When the main body 1 is overheated, Figure 3 As shown, first, the heat sensor 3 installed on the inner wall surface of the housing 2 will be sensed, and then the heat sensor 3 will control the motor 4 to start. Since the front end of the motor 4 is fixedly connected with the bevel gear 5, and the bevel gear 5 is meshed with the bevel gear 5 on the outer surface of the screw rod 6, the screw rod 6 is rotated. Since the outer surface of the screw rod 6 is connected to the convex plate of the moving plate 7, the screw rod 6 will move the moving plate 7 upward, as shown in FIG. Figure 2 As shown, since the convex plates on both sides of the movable plate 7 are below the sac 9, the upward movement of the movable plate 7 will squeeze the sac 9. At the same time, the openings at both ends of the coolant tube 8 are connected with the sac 9, so the internal coolant will enter the coolant tube 8. The pipe arranged at the connection between the sac 9 and the coolant tube 8 is a hose, and the movement of the coolant tube 8 will not affect the connection. When the coolant tube 8 reaches the bottom of the main body 1, the main body 1 will be cooled down quickly. After cooling down, the motor 4 will start to reverse, so that the movable plate 7 drives the coolant tube 8 to move downward, so that the sac 9 will recover the coolant in the coolant tube 8, which is convenient for the natural cooling of the coolant.

[0037] When connecting and installing, firstly, the pressure ring 10 on the side surface of the housing 2 is docked with the connection, and then the pressure ring 10 is squeezed so that the pressure ring 10 slides on the side surface of the housing 2, and then the pressure ring 10 pushes the push plate 12, and the threaded hole of the link corresponds to the threaded rod 11, and then the push plate 12 will squeeze the airbag 13, as shown in FIG. Figure 4 As shown, the airflow inside the airbag 13 will flow to the tooth plate 16 through the air pipe 15. The tooth plate 16 is connected to the piston of the air pipe 15, so that the tooth plate 16 moves, and the tooth block on the lower surface of the tooth plate 16 will drive the main gear 14 to rotate, so that the main gear 14 drives the threaded rod 11, and the threaded rod 11 will rotate into the docking hole for spiral rotation connection. The operation is simple and the installation is quick. A push rod 17 is also installed on the front surface of the tooth plate 16, and the push rod 17 corresponds to the opening on the outer surface of the shell 2.
