Tire pressure warning device with adjustable tire pressure setting
First Claim
1. A tire pressure warning device with adjustable tire pressure setting for being removably connected to a valve on a tire so as to show a warning signal when the tire has an insufficient tire pressure, comprising:
- a casing being internally provided with a transverse partition, having a central hole, to divide the inner space of said casing into an upper chamber and a lower chamber, and said upper chamber being provided at an inner side near the top thereof with an annular shoulder portion;
a valve structure mounted in said lower chamber of said casing;
a membrane mounted on the top of said transverse partition;
a bushing mounted in said upper chamber of said casing and located above an annular outer peripheral portion of said membrane, and being provided at the top with a through hole;
a push member including a push bar, said push bar being located in said bushing with a lower end of said push bar pressed against said membrane and an upper end upward projected from said through hole of said bushing; and
said push bar being formed near the lower end with a radially extended flange;
an elastic element being mounted around said push bar of said push member and being located between said flange of said push member and the top of said bushing;
at least one pressure-adjusting element being mounted on the top of said push member;
a cover being provided at a predetermined position with a through hole, and mounted around the top of said casing; and
an elastic fixing element for elastically positioning said at least one pressure-adjusting element between said push member and said cover.

Abstract
A tire pressure warning device with adjustable pressure setting includes a case divided into a lower and an upper chamber and having a shoulder portion formed near a top thereof; a valve structure mounted in the lower chamber of the case; a membrane, a bushing, a push member, an elastic element, and a pressure-adjusting element sequentially mounted in the upper chamber of the case; and a cover connected to the top of the case. While the elastic element defines a basic pressure setting for the device to measure the air pressure inside a specific type of tire, a pressure-adjusting element with a suitable thickness may be selected to adjust the tightness of an elastic fixing element and thereby changes the pressure setting for the device, so that the device could also be used to measure the tire pressure of other different types of tires.
