Abstract
The utility model relates to an auxiliary tyre inflating device for a motor vehicle tyre, which is an automatic tyre inflating valve for inflating the motor vehicle tyre conveniently, comprising an eccentric cam handle, a valve body, a valve core and a rubber band. The bottom of the valve body is provided with an air valve trepan boring, the rubber band is arranged between the bottom of the valve body and the valve core, the bottom of the valve core is provided with a thimble and at least one air outlet, the upper part of the valve core is provided with an air inlet pipe which is communicated with the air outlet, and the air inlet pipe is communicated out of the chute at the flank of the valve body whose top is provided with the eccentric cam handle. The utility model has the advantages of simple structure, easy fabrication and convenient use, and the inflating air pressure of the tyre can be controlled by one person to operate.
Description
The utility model relates to motor vehicle tire supplemental inflatable device, is a kind of automatic tyre air inflation valve.
The charging connector of general motor vehicle tire withstands plunger by spring and controls the air passage switching.During inflation, must could inflate with the gas filled device unseat the valve pin of band thimble.At present, can only withstand by manpower, so just very inconvenient, when needing to inflate in the power actuated vehicle long-distance transport for winter especially, especially difficult.
The purpose of this utility model is to overcome the deficiencies in the prior art and designs a kind of automatic tyre air inflation valve that can make things convenient for tire carbonation of motor vehicle.
The purpose of this utility model reaches by following measure: this automatic tyre air inflation valve, comprise eccentric cam handle, valve body, valve core, rubber band, the bottom of valve body has the tire tube valve trepanning, between the bottom of valve body and spool, rubber band is housed, there is thimble the bottom of spool and is no less than one the core that goes out, the top of spool has and goes out the air inlet pipe that core communicates, and from the chute pass-out of valve body side, the eccentric cam handle is equipped with at the top of valve body; Bottom at valve body is equipped with the adjustment cover by screw thread.
The utlity model has simple in structure, easy manufacturing, characteristics such as easy to use, and the one man operation is the air pressure of may command inflation of tire, and sealing property is fine, outward appearance appearance exquisiteness, easy to carry.
Accompanying drawing one is the structural representation of the utility model embodiment, and accompanying drawing two is the running condition structural representation of the utility model embodiment, being encoded in the accompanying drawing: 1 is the eccentric cam handle, 2 is valve body, 3 is valve core, and 4 is rubber band, and 5 is the tire tube valve trepanning, 6 is thimble, 7 for going out core, and 8 is air inlet pipe, and 9 is chute, 10 for adjusting cover, and 11 is rivet or screw rod.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: as accompanying drawing one, shown in two, this automatic tyre air inflation valve comprises eccentric cam handle 1, valve body 2, valve core 3, rubber band 4, the bottom of valve body 2 has tire tube valve trepanning 5, between the bottom of valve body 2 and spool 3, rubber band 4 is housed, there is thimble 6 bottom of spool 3 and also has two to go out core 7, the top of spool 3 has and goes out the air inlet pipe 8 that core 7 communicates, relatively respectively there is a chute 9 valve body 2 sides, air inlet pipe 8 can be installed in eccentric cam handle 1 with rivet or screw rod the top of valve body 2 from one of them chute 9 pass-out; During use, shown in accompanying drawing one, two, the inflation of tire muzzle is gone in the tire tube valve trepanning 5, and make thimble 6 back down plunger in the inflation of tire mouth to pressing down, then, eccentric cam handle 1 is removed to a side, spool 3 is moved down press rubber band 4, thereby rubber band 4 and inflation of tire tight-lipped connecting airtight are touched, play sealing function, and the automatic tyre air inflation valve is fixed on the inflation of tire mouth, so only need the control inflation pressure, after inflation of tire reaches required pressure, removed eccentric cam handle 1, just can take off the utility model, finish the inflation of tire process.Because of rubber band 4 wears out easily, for the ease of changing rubber band 4, shown in accompanying drawing one, two, bottom at valve body 2 is equipped with adjustment cover 10 by screw thread, have tire tube valve trepanning 5 in the bottom of adjusting cover 10, and change the gap of rubber band 4 by turn adjustment cover 10, thereby adjust the utility model sealing effectiveness of rubber band 4 in use.
Claims (2)
1, a kind of automatic tyre air inflation valve that is used for tire carbonation of motor vehicle, comprise eccentric cam handle 1, valve body 2, valve core 3, rubber band 4, the bottom that it is characterized in that valve body 2 has tire tube valve trepanning 5, between the bottom of valve body 2 and the spool 3 rubber band 4 is housed, the bottom of spool 3 thimble 6 is arranged and be no less than one go out core 7, the top of spool 3 has and goes out the air inlet pipe 8 that core 7 communicates, and from chute 9 pass-outs of valve body 2 sides, eccentric cam handle 1 is equipped with at the top of valve body 2.
