An inflator cap comprising: an outer cover; an anti-corrosion lining formed in or inside the outer cover; and a magnetic member formed on, in or inside the outer cover, whereby the magnetic member of the inflator cap, once unscrewed from the inflator, will be magnetically attractable on a ferromagnetic object to prevent its loss; or whereby the anti-corrosion lining will preclude a direct contact between the outer cover of the inflator cap and a valve stem of the inflator to prevent from sticking of the oxide of the outer cover once oxidized on the valve stem of the inflator, thereby smoothly unscrewing the cap from the inflator.

Unscrewable and magnetically attractable inflator cap

A multiple-in-one socket includes a socket body having a first gradational cavity recessed in a first end of the socket body, and a second gradational cavity recessed in a second end of the socket body opposite to the first gradational cavity; each gradational cavity including a plurality of polygonal holes gradationally contracted in sizes inwardly from an outermost hole towards an innermost hole; whereby a plurality of polygonal holes having plurality of hole sizes may be conveniently chosen for fastening a bolt or nut by correspondingly matching the bolt (or nut) size with the polygonal-hole size.

Multiple-in-one socket

An anti-wearing nut or bolt including a plurality of polygonal sides circumferentially formed on a head portion of the nut or bolt and; each polygonal side including: two inclined sub-sides respectively inclined outwardly convergently from opposite apexes of each polygonal side, each inclined sub-side extrapolatively defining a small biasing acute angle between each inclined sub-side and a corresponding socket side, and an intermediate sub-side transversely intersecting the two inclined sub-sides; whereby upon a clockwise or counter-clockwise rotation of the socket, one inclined sub-side of the nut or bolt will be planarly engaged with each socket side, without being linearly bitten or dogged, to thereby prevent wearing or damage of the apexes of the nut or bolt.

Anti-wearing nut and bolt

A vehicle protection device includes a wiper externally mounted on the wheel rim as fastened by an inflation valve fixed in the wheel rim, and a sensor holder engaged with the inflation valve and positioned inside the wheel rim for holding a tire pressure sensor within the wheel rim and within a tire; whereby the sensor will sense the tire pressure for safely monitoring the tire pressure; and the wiper will scrape the rain water (or snow) outwardly from the wheel for enhancing driving safety.

Vehicle protection device directly formed on inflation valve

A socket includes an inner lining detachably formed in an inner hole within the socket, with the inner lining formed therein with a differentially-sized torque recess including at least a large hexagonal hole defining a large diagonal distance (D) between two diagonal points of the large hexagonal hole and a small hexagonal hole gradationally contracted inwardly from the large hexagonal hole and defining a small diagonal distance (D) between two diagonal points of the small hexagonal hole, so that each inner lining may be provided for selectively engaging at least two differently-sized nuts (or bolts) for convenient and economic torquing purpose.

Anti-wearing socket and inner lining thereof

An anti-steal tire pressure monitoring apparatus includes: a tire valve; a tire pressure sensor and transmitter connected with a tire inflation valve of the tire valve; an inner cap having the tire pressure sensor and transmitter encased in the inner cap and engaged with a valve seat of the tire valve; and an outer sleeve free rotatably engaged with the inner cap; whereby upon tightly screwing of the inner cap with the valve seat of the tire valve to depress the inflation valve to allow the air entering the sensor for detecting the tire pressure, any rotation (counter rotation) of the outer sleeve trying to unscrew the inner cap will be ineffective, since the outer sleeve is free rotatably engageable with the inner cap, so as to safely 'lock' the inner cap and the tire pressure sensor and transmitter on the tire valve without being stolen or removed from the tire valve.

Anti-steal tire pressure monitoring apparatus

A wireless tire pressure alarming system includes a tire pressure sensor & transmitter attached to each car wheel for sensing the tire pressure in each car wheel and for remotely sending the tire pressure signal from each car wheel; and a receiver having a plug plugged in a car cigarette-lighter receptacle to be powered by the car battery through such a cigarette-lighter receptacle and for receiving the tire pressure signal from the car wheel; whereby upon detection of a tire pressure reduced below the pre-determined safety pressure value of each car wheel, an alarm will be actuated either by an optical alarm signal or a sound alarm signal for warning the car driver for inflating his or her car wheel for enhancing driving safety.

A wheel rim includes two centripetal flanges respectively centripetally formed on an inner and an outer portion of a drop-center portion of the wheel rim having different displacements of the two centripetal flanges respectively deviated from a longitudinal center plane centrally defined between an inner rim flange and an outer rim flange of the wheel rim, with the longitudinal center plane being projectively perpendicular to a central axle axis of the wheel rim, thereby simultaneously satisfying two types of cars, one having a larger off-set and the other having a smaller off-set of each wheel disk as respectively deviated from the longitudinal center plane of each wheel rim.
