Detailed Description

The tire pressure display device of the present invention, please refer to fig. 1, mainly includes a tire 2 tightly covering the periphery of each rim 1 of the vehicle and filled with air pressure, and an inflating valve 3 assembled at a proper position of the rim 1 side connected to the inside of the tire 2.

Wherein,

the first implementation setting (please refer to fig. 1 and 2) for conveniently judging the internal air pressure of the tire of the present invention is: each rim 1 is communicated with the proper layer of the tire pressure filled in the tire 2 and is connected with a display device 4, the display device 4 is a hollow transparent scale contrast pipe 41 which is formed with obdurability and protrudes out of the rim 1, a containing pipe 42 with a periphery wound with an elastic component 43 which extends in a spiral shape and has considerable strength is formed by the lowest basic section in the scale contrast pipe 41, a periphery layer wall of the spiral extending elastic component 43 is covered between the containing pipes 42, and the containing pipes are formed by obdurability; the display device 4 is formed by correspondingly propping up and extending the containing pipe 42 communicated with the air pressure of the tire 2 for equal air pressure 5, and the top end of the containing pipe 42 moving outwards corresponds to the corresponding scale 44 of the scale comparison pipe 41, so that a driver can simply, conveniently and quickly know whether the value of the tire pressure in the tire 2 is normal or low through the display device 4, and the maintenance basis of the optimal condition is carried out on each tire 2 of the vehicle at the right time.

The display device 6 designed by the present invention can also be installed on the valve 3 (refer to fig. 3) of each rim 1 of the vehicle connected to the proper layer of the tire 2 filled with air pressure, the display device 6 tightly screwed on each valve 3 is a transparent hollow scale accommodating seat body 61 formed by tough material, the scale accommodating seat body 61 is formed by inner and

outer tube sections

611, 612 with closed bottom and open top, the inner thread section 613 on the upper end of the inner tube section 611 can be screwed on the inflating end of the valve 3, the other lower end tightly covers the outer periphery of the valve 3, and the annular groove space 614 inside the scale accommodating seat body 61 can be sequentially sleeved with the elastic component 62, the inner periphery, the abutting washer 63 with the air-

tight ring rings

64, 65, and the abutting washer 63 with the inner periphery and the outer periphery corresponding to the scale accommodating seat body 61, The

outer tube sections

611, 612 are sealed, and a top cover 66 of a pressing section 661 is disposed at the upper opening of the scale housing body 61 to be a pressing screw lock and protruded toward the sealing thimble 31 of the valve 3 from the center; therefore, the air pressure 5 inside the tire 2 is conducted to enter the display device 6 and press the elastic washer 63 therebetween, and the scales of the seat body 61 are accommodated by the corresponding scales of the elastic washer 63, so that a driver can quickly and simply judge whether the air pressure value inside the tire 2 is normal or low by the display device 6, and the early warning safety equipment for preventing the serious abrasion of the vehicle tire 2 caused by the simple air leakage problem is effectively avoided.

The display device 6 of the present invention can be screwed on each valve 3 by extending a second valve 67 (see fig. 4) from the top of the top cover 66 of the third figure, so that the driver can directly inflate the valve from the second valve 67 at the filling pressure.

The display device of the present creation spin lock on each valve 3 can also be designed as the form shown in fig. 5, and directly fasten the pressure gauge 7 with an elastic spring 71 and an extending pointer 72 on the valve 3, so as to press the airtight thimble 31 at the center of the valve 3 by the abutting portion 73 at one end, and the pressure gauge 7 can display whether the air pressure value inside the tire 2 is normally suppressed to a low value at the right time.

In addition, the pressure gauge 7 used in the display device directly screwed on the valve 3 disclosed in fig. 5 may also be installed as shown in fig. 6, that is, an elastic component 75 is sleeved between the bottom of the pressure gauge 7 and the top cover 74 of the screw lock above the valve 3, so that the driver can determine the air pressure value inside the tire each time, and the pressure gauge 7 is pressed down by the finger, so as to conduct the air pressure inside the tire and the valve 3, thereby forming a normally closed display tire pressure device.
