<p>An external tire pressure gauge and a mounting structure thereof comprising a base (2) that provides an external thread peripheral wall (21) and a cap (1) that provides an internal thread peripheral wall (131), the base (2) and the cap (1) being locked with each other in a threaded manner to provide an inner mounting space (10). In addition, the mounting structure also comprises a gear (3), a backing ring (4), and a locking piece (5); the gear (3) is fixed to a bottom surface of the base (2) and is provided with gear teeth (30) along the peripheral direction; the backing ring (4) is provided with a through hole (48), and gear teeth (40) are arranged on a peripheral wall of the through hole (48); the backing ring (4) is sleeved at the periphery of the gear (3) by means of the through hole (48), and the backing ring (4) and the gear (3) are arranged in such a manner that the gear teeth (30, 40) thereof are engaged with each other; the locking piece (5) is adhered to the backing ring (4) and the gear (3); the locking piece (5), the gear (3), and the base (2) are each provided with a screw hole for screw lock with an inflating valve rod (6). Also disclosed is a corresponding mounting and dismounting tool. With the modified tire pressure gauge and the mounting structure thereof, as well as the provided mounting and dismounting tool that facilitates operation, the mounting and dismounting of the tire pressure gauge are more convenient.</p> |
