Description

The electronics tire gauge of rotatable pressure measuring tie-in

The utility model relates to a kind of electronics tire gauge of rotatable pressure measuring tie-in, be to make the pressure measuring tie-in of this electronics tire gauge set up jointly with the revotating card that the tire gauge body is designed to the adjusting microinching formula, also can one luminous element be installed at the pressure measuring tie-in chosen place, make its rotatable pressure measuring tie-in and obtain best taking measurement of an angle, and suitable illumination can be provided in the dark.

Traditional pressure of tire meter, mainly be to utilize a measurement column that is placed in the tire gauge body tip, utilize tire pressure to be measured different and present the expanding-contracting action of different amplitudes, and show tire pressure situation to be measured by the scale of measurement column, the outreach of this measurement column is also big when tire pressure is higher, otherwise the outreach of measurement column is then little.Another kind of electronics tire gauge design, mainly be that admission piece inwall at pressure measuring tie-in is provided with a pressure detection electronic component, and the tire gauge body is interior and outer wall has circuit card (PC plate) respectively, LCD panel, assembly such as shift knob and battery, like this, after the admission piece of pressure measuring tie-in inserts cranked tire valve, but promptly utilize pressure detection electronic component perception tire pressure to be measured, and with numeric display in LCD panel, but this kind known electronic tire gauge, because pressure measuring tie-in and tire gauge body are secure bond, and vehicle tyre is when static, the cranked tire valve of four tires of cause all is in not certain location, so the pressure measuring tie-in of tire gauge must be yielded to the cranked tire valve present position and just can carry out the tire pressure surveying work, but cranked tire valve always is positioned at the not ad-hoc location of tyre beads wall when tire is static, therefore can't make LCD panel all can consequently usually will pull up the tire pressure value that tire gauge just can view its demonstration correctly towards the user at all, also convenient not to the utmost in the use.And this tire gauge because of tool is any from not establishing the lamp source, also seems difficult inconvenient so the user will seek the tram of cranked tire valve in the dark or under the not enough environment of light source.

Main purpose of the present utility model, it is the electronics tire gauge that is to provide a kind of rotatable pressure measuring tie-in, be to make the pressure measuring tie-in of electronics tire gauge be revolving movable the combination with the tire gauge body, particularly one block is set at pressure measuring tie-in inner side edge wall, and fixedly install a shell fragment in the corresponding position of tire gauge body, so can put in order the optimum measurement angle of pressure measuring tie-in in 360 degree scope inward turning modulations arbitrarily, and conveniently be engaged in the measurement of pressure of tire and the work of checking of tire pressure numerical value.

Secondary objective of the present utility model, it is the electronics tire gauge design that is to provide a kind of rotatable pressure measuring tie-in, it is that inner side edge wall setting at electronics tire gauge pressure measuring tie-in is a plurality of grooves around shape, and the shell fragment of tire gauge body also has corresponding protruding grain, with the protruding grain that makes this shell fragment just can with the forming the adjusting microinching formula around the shape groove and engage of pressure measuring tie-in inner side edge wall, so can rotate pressure measuring tie-in arbitrarily determining taking measurement of an angle of its best, and when angular adjustment, can obtain the effect of preferable engaging location.

Another purpose of the present utility model, it is the electronics tire gauge design that is to provide a kind of rotatable pressure measuring tie-in, it further also can install a luminous element at the chosen place of pressure measuring tie-in, make it provide suitable illumination in the dark or under the not enough environment of light source, seek the tram of cranked tire valve to make things convenient for the user.

Following conjunction with figs. describes feature of the present utility model and advantage in detail:

Fig. 1 is a combination stereogram of the present utility model.
