Abstract
The utility model relates to a burst-proof device for tyres, which comprises an air valve body, an installation sleeve, an inner sleeve, etc., wherein, a pressure decreasing burst-proof device is arranged in a through hole of the air valve body; one end of an exhaust pipe is provided with a sealing gasket and then is sheathed with the inner sleeve; the other end of the exhaust pipe is sheathed with a spring and then is arranged in the installation sleeve; in such a way, the burst-proof device is formed. The utility model has the advantages of simple structure, small volume, low cost, easy popularization and use and is the optimal burst-proof device when the tyre is inflated.
Description
The utility model relates to a kind of explosion-protection equipment of tyre.
During inflation of tire, very easily because of the improper tire blow-out that makes of air pressure control, particularly use common Floor Pump to bicycle, blow out during the inflation of wooden handcart tire and happen occasionally especially, " explosion-protection equipment of tyre " as Chinese patent ZL96224549.6, promptly be to a kind of explosion protection of inflation of tire design-calculated, it comprises overcoat and the exhaust decompression valve that is installed on the tire valve, put outward and valve bonded assembly relief chamber, induction opening and deflation hole are arranged on the relief chamber, valve inside is loaded on the induction opening, reducing valve and air-pressure gauge are housed, so explosion-proof purpose when reaching between induction opening and deflation hole to inflation of tire.Though this device plays explosion-proof during to inflation of tire, its structure relative complex need to use reducing valve and air-pressure gauge, and cost is higher, is difficult for promoting the use of.
The purpose of this utility model will provide a kind of structure extremely simple exactly, does not need to use more expensive spare and accessory parts, and cost is low, and is easy to use, the tyre explosion-proof equipment of very easily promoting the use of.
The purpose of this utility model is achieved like this: it comprises valve body, installation sleeve, interior cover etc., in the through hole of valve body, be provided with the decompression explosion-proof device, described decompression explosion-proof device, promptly be in a termination of freeing pipe packing seal to be housed to put interior cover, in the installation sleeve of packing into behind the cover upper spring of other end.
The utility model tyre explosion-proof equipment is simple in structure owing to using said structure to make that it has, volume is little, productive costs is extremely low, only need direct mount use on existing tyre valve core, do not need the other parts of tire are done any change, it is extremely convenient to install and use, and the inflation of tire that is suitable for unpowered vehicle and self-propelled vehicle uses.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model tyre explosion-proof equipment.
Among the figure: the 1-installation sleeve, the 2-spring, the 3-valve body, the 4-packing seal,
The 5-freeing pipe, cover in the 6-, 7-internal thread, 8-inlet, gas access during inflating on the valve body 3,9-through hole, cover aperture in the through hole on the valve body 3,10-.
Tyre explosion-proof equipment as shown in Figure 1 is provided with the decompression explosion-proof device in the through hole 9 of valve body 3, its explosion protection comprises valve body 3, installation sleeve 1, freeing pipe 5, interior cover 6 etc., cover 6 in after packing seal 4 is loaded onto in the termination of freeing pipe 5, putting, pack into behind the other end cover upper spring 2 in the installation sleeve 1, cover aperture 10 on interior cover 6, having, when needs during to inflation of tire, internal thread 7 on the valve body 3 of explosion-proof apparatus is loaded on the valve inside of tire, when inflation of tire, gas is through inlet 8, valve inside fills in the tire, when tire pressure reached specified air pressure, gas applied certain pressure by the packing seal 4 on 10 pairs of freeing pipes 5 of interior cover aperture, and its pressure is greater than the elastic force of spring 2, make length of spring compressed, the gap appears in packing seal 4 places, and gas is discharged through freeing pipe 5, and tire is no longer inflated, thereby prevented from effectively to have guaranteed inflation of tire safety owing to the too high accident that makes tyre break of air pressure.
