[0004] However, when this type of temperature and pressure sensor is in use, since the temperature and pressure sensor is directly connected to the engine intake pipe through a threaded connection, the vehicle will experience bumps and vibrations during driving, which may cause the connection to loosen after long-term use. At the same time, the connection is only sealed by the sealing ring of the temperature and pressure sensor. Once the sealing ring ages, the sealing effect will drop sharply, affecting the detection accuracy of the temperature and pressure sensor. Utility Model Content

[0005] The utility model provides an automotive temperature and pressure sensor capable of rapid response. By providing an external gasket, it can cooperate with the sealing ring of the temperature and pressure sensor itself to seal the connection position between the temperature and pressure sensor and the engine intake pipe. During use, even if the sealing ring ages, the external gasket can rely on it to seal the connection between the two, ensuring the detection accuracy of the temperature and pressure sensor body. At the same time, through the cooperation of the arc-shaped support plate and the arc-shaped abutting block, the connection of the temperature and pressure sensor can be strengthened, reducing the probability of loosening at the connection of the temperature and pressure sensor. This solves the problem that when this type of temperature and pressure sensor is used, since the temperature and pressure sensor is directly connected to the engine intake pipe by a threaded connection, the vehicle will experience bumps and vibrations during driving, and after long-term use, the connection may become loose. At the same time, only the sealing ring of the temperature and pressure sensor itself is used to seal the connection. Once the sealing ring ages, the sealing effect will drop sharply, affecting the detection accuracy of the temperature and pressure sensor.

[0032] Please refer to Figures 1-7 , an automotive temperature and pressure sensor capable of rapid response, including an engine intake pipe, a body of temperature and pressure sensor, a terminal connector and a threaded joint. The threaded joint is threadedly connected to the engine intake pipe, and the body of temperature and pressure sensor is communicatively installed on the surface of the threaded joint. The terminal connector is fixedly connected to the surface of the body of temperature and pressure sensor;

[0033] A mounting ring is rotatably sleeved on the surface of the body of temperature and pressure sensor. Four hollow outer rods are fixedly connected to the surface of the mounting ring in a rectangular array. An L-shaped connecting rod is slidably connected to the inside of each hollow outer rod.

The bottom end of each connecting rod is fixedly connected with a mounting block. An arc-shaped support plate is fixedly connected between the two mounting blocks. The radian of the arc-shaped support plate is adapted to the radian of the engine intake pipe.

[0034] Adjusting bolts are symmetrically threadedly connected to the surface of the mounting ring. Each adjusting bolt penetrates the surface of the mounting ring and extends into the inside of the mounting ring and abuts against the outer shell of the body of temperature and pressure sensor.

[0035] Strip-shaped chutes are symmetrically opened on the inner wall surface of the hollow outer rod. Limit sliders are symmetrically fixedly connected to the surface of the L-shaped connecting rod. The limit sliders are inserted into the strip-shaped chutes, and the limit sliders are slidably connected to the hollow outer rod.

[0036] An arc-shaped rubber pad is fixedly connected to the inner wall surface of the arc-shaped support plate.

[0037] The surface of the positioning block is threadedly connected with a second screw rod, the top end of the second screw rod is fixedly connected with a hand wheel, and the bottom end of the second screw rod is rotatably connected with a resisting rubber block.

[0038] The resistance rubber blocks and arc-shaped rubber pads are made of natural rubber and synthetic rubber, and have the characteristics of high elasticity, high wear resistance, high pressure resistance, and high tear resistance.

[0039] When using the temperature and pressure sensor, first install the temperature and pressure sensor on the engine intake pipe. During installation, unscrew the nut and pull the arc-shaped support plate out from the surface of the positioning block. Then use the threaded joint to screw the temperature and pressure sensor body into the engine intake pipe and tighten it.
