Description
Technical Field
The utility model belongs to the technical field of inflation equipment technique and specifically relates to indicate a comfortable type tire air entrainment device who aerifys and detect inside tire pressure at any time for various vehicles.
Background
The travel of various vehicles is moved by the movement of tires over the ground. The inflation quantity of the pneumatic tire directly influences the friction force between the pneumatic tire and the ground, so that the running speed of the vehicle is influenced, and the effective output power of the power is finally influenced. Therefore, before the vehicle runs, people inflate the tires and detect the inflated tire pressure so as to reach the ideal condition of design. At present, when tires of various vehicles are inflated, a trigger type inflation gun is generally adopted, and because the trigger of the inflation gun simulates the trigger of a gun, a user needs to open the thumb and other four fingers as much as possible when using the inflation gun, and when the tire pressure after inflation is detected, the user needs to lift the wrist to see specific data of the measuring meter; and a mechanical measuring structure is adopted, so that measuring errors exist.

The air adding pipe and the pressure measuring pipe are horizontally fixed on the main body.
The utility model discloses owing to change into the formula of gripping handle with original wrench type handle for it is more laborsaving and convenient in the use of hand to inflate the operator, has fine market value.
Description of the drawings:
FIG. 1 is a main sectional view of the present invention;
FIG. 2 is an enlarged view of FIG. 1 at A.
The specific implementation mode is as follows:
referring to the attached drawings 1-2, a comfortable tire inflating device comprises a main body 1, an inflating pipe 2, a wrench 3, a valve core 4, a pressure measuring pipe 5 and a fixing frame 6, wherein the inflating pipe 2 and the pressure measuring pipe 5 are fixed on the main body 1, the inflating pipe 2 is communicated with an inflating air passage 12 in the main body 1, the pressure measuring pipe 5 is communicated with a pressure measuring air passage 13 in the main body 1, the fixing frame 6 fixedly connects the inflating pipe 2 and the pressure measuring pipe 5 into a whole, the wrench 3 is rotatably connected on the main body 1 through a pin shaft 31, the valve core 4 is slidably arranged in a shaft hole in the main body 1, one end of the valve core 4 is fixedly clamped with a pushing spring 44 fixedly arranged on the main body 1, the other end of the valve core 4 is propped against the bottom surface of the wrench 3, an axial groove 43 is arranged in the middle of the valve core 4 outside the groove 43, a sealing ring 41 and an air inlet sealing, the air inlet 11 is communicated with an axle hole at one end of the valve core 4 close to the air inlet sealing ring 42, the air inlet sealing ring 42 is positioned between the air inlet 11 on the main body 1 and a middle groove 43 of the valve core 4, the air charging air passage 12 and the pressure measuring air passage 13 are respectively communicated with the axle hole of the valve core 4 arranged in the main body 1, and the positions of the air charging air passage and the pressure measuring air passage respectively correspond to the axial groove 43 at the middle of the valve core 4.
The air adding pipe 2 and the pressure measuring pipe 5 are horizontally fixed on the main body 1.
When the utility model is applied, an external air source is connected into the air inlet 11 of the main body 1, the wrench 3 is pressed, the wrench 3 rotates anticlockwise around the pin shaft 31 because the wrench 3 is hinged, and the valve core 4 overcomes the elasticity of the pushing spring 44 on the main body 1 and moves downwards along the shaft hole where the valve core 4 is positioned under the action of the wrench 3; when the air inlet sealing ring 42 on the valve core 4 moves out of the shaft hole, the axial groove 43 in the middle of the valve core 4 enters the air inlet 11 section of the main body 1, and air enters the air filling pipe 2 after passing through the air inlet 11, the axial groove 43 in the middle of the valve core 4 and the air filling air channel 12, and inflates the tire; meanwhile, the sealing ring 41 is positioned in the axial hole of the main body 1 between the inflation air passage 12 and the pressure measurement air passage 13, and seals the air passage between the air inlet 11 of the main body 1 and the pressure measurement air passage 13, so that no gas passes through the pressure measurement air passage 13, and at this time, the tire is inflated.
The wrench 3 is loosened, the valve core 4 moves upwards in the shaft hole under the action of the resilience force of the pushing spring 44, the air inlet sealing ring 42 moves upwards synchronously, the air inlet sealing ring 42 stops at the original position, namely, the passage between the air inlet 11 and the air charging air channel 12 is closed, and the tire stops inflating; at this time, the sealing ring 41 is displaced to the outside of the pressure measuring air passage 13, the inflation pipe 2, the inflation air passage 12, the axial groove 43 in the middle of the valve core 4 and the pressure measuring air passage 13 form a connected loop, and the air pressure in the tire is reflected by an air pressure gauge arranged at the front end of the pressure measuring pipe 5.
