Abstract
The utility model discloses an automatic alarm arranged on the air tap pile of the inner tyre of a vehicle tyre, and the air inflation of the vehicle tyre is not be influenced. A sealing inner tube is arranged in the inner liner of a casing, the sealing inner tube comprises a sealing block and an air pressure spring, a slit air passage is cut on the long direction of the inner tube, and a casing bottom is screwed with a dust cap in which sound sheets are arranged. When air pressure in the tyre is insufficient, the air pressure is extended, air current in the tyre extruded from the slit air passage to vibrate the sound sheets to give a sharp alarm sound, and a driver can be prompted to immediately stop. Practical values are given to prolong tyre service life and avoid the occurrence of traffic accidents.
Description
The utility model is a kind of warning device of pointing out tire internal gas pressure deficiency.
Tire is the exhausted indispensable parts of vehicle operating, keeps enough air pressure not only to be of value to the gait of march of vehicle in the tire, more helps safety.Tire internal gas pressure deficiency does not just influence the speed of a motor vehicle, and can force as giant tyre and ground-surface friction force, and tire then is easy to damage and leaks gas, and as untimely discovery, also can lead to traffic accident when serious, and consequence is hardly imaginable.
The utility model provides a kind of tire autoalarm, and purpose is when in the tire in the vehicle operating during unsaturated vapor, can make prompting in the mode of blowing a whistle automatically.
Technical solution of the present utility model is as shown in the figure:
Accompanying drawing 1 is the structural representation of the utility model in non-alarm condition.
Accompanying drawing 2 is the structural representation of the utility model under alarm condition.
Among the figure: 1 is that shell, 2 is the sawtooth hard packing for pronunciation rings sheet, 9 for dust cap, 8 for tire inner tube valve stake, 7 for slit, 6 for sealing block, 5 for gas spring, 4 for interior pipe, 3.10 are pore for tightening seal washer, 11,12,13.
The utility model is the pipe body, is lined with the inner tube 2 with its sealing in shell 1, in Include gas spring 2 in the pipe, sealing block 4, and in the length of inner tube to having slit 5. Shell one end links to each other with tube valve stake 6 by interior screw thread, and the other end is rotary with dustproof Pronunciation clicker 8 is installed in the cap 7, cap, the sealing block shown in other figure, it is towards the valve stake One side be fitted with as circumferential arrangement and become sawtooth hard packing 9, hard packing and sealing block are one whole in fact Body; Shell and valve stake abutting end inwall internal diameter be greater than the internal diameter of sealed inner tube 2, both Joint leaves gas at the bottom of being provided with seal washer 10, the shell of packing ring central authorities for pore 11, shell Hole 12, dust cap outer vent 13. The length of slit is about 1/3rd of interior length of tube.
The utility model use-case:
Take off the valve inner core of vehicle tyre, the utility model is tightened in the inner tube air valve stake 6, just not enough as former tolerance in the tire, by dust cap pore 13 gas injection in tire, air communication is crossed shell spirit hole 12, advance gas injection pressing spring 3 cavitys, enter the sawtooth space of hard packing 9 by slit 5 again and enter in the tire from tightening seal washer 10 air pressure.Sufficient gas reaches certain air pressure intensity in tire, just can not inflate in tire from pore 13, tire internal gas pressure air communication via hole 10 rushes at sealing block 4 again, and gas spring compression surmounts 5 (see figure 1)s of slit, and to be equivalent to slit 5 also be the sealing shape, tire is in the normal state, the normal smooth running of vehicle.In case but tire flat, tire internal gas pressure are lower than at 1/4 o'clock of former air pressure, gas spring 3 is upheld, sealing block is pushed to and moves ahead, and no longer seal as the slit that air communication is crossed, gas enters spring cavity flush gas hole 12 by slit in the tire, rings sheet and is shaken, and sends sharp-pointed chimes of doom from pore, disappear until the tire internal gas pressure, shell internal gas pressure spring 3 is upheld fully and is put in place simultaneously, pushes away before the sealing block, and whole air flue is unobstructed shape.The chaufeur comrade hears chimes of doom, can stop immediately, changes spare tyre, row inflation etc. again, and vehicle then recovers normal operation shape again.In addition: to the tire autoalarm of different model, wherein gas spring can hold gas air pressure and fixed its model by tire.
The utility model structure is ingenious, compact, easy to use, actual measurement vehicle speed per hour all can clearly heard more than 80 kilometers, and speed per hour is better with next effect at 60 kilometers, reached the desired design purpose,, avoided causing the actual value that has of traffic accident because of damaged tyres to prolonging tire service life.
