Abstract
An anti-deflation valve cap design by the utility model is provided, which comprises a cap body, a round connecting hole is arranged at one end of the cap body, a connecting structure is positioned inside the round connecting hole, a protruding valve core deflation column is arranged at the bottom center of the round connecting hole and a ventilating through hole is arranged at the circular center of the valve core deflation column; the ventilating through hole is communicated with the annular air outlet, the annular air outlet is airtightly connected with the pressure-limiting gasket, a pressure-limiting spring is positioned at the back of the pressure-limiting gasket, the pressure-limiting spring is connected with the adjustable locking structure, the adjustable locking structure is connected at the other end of the cap body and an exhaust hole is arranged at the end. The tail end of the adjustable locking structure is provided with a pressure display device, which can visually display the pressure index of the pressure-limiting spring. When the tire pressure exceeds the pressure limit safety, the anti-deflation valve cap can be used to automatically and properly release the air in the tire to relief high pressure in the tire, ensure that the tire pressure is kept within the safety range and effectively prevent deflation accidents due to excess tire pressure.
Description
Technical field
The utility model relates to dust cap, particularly a kind ofly can effectively control tire pressure within safety range, thereby effectively prevents a kind of tire puncture preventing valve nozzle cap of the accident of blowing out.
Background technique
Existing tire usually occurs in use because tire pressure overcharges or tyre temperature rising in driving process, and internal gas expands, and the tire internal pressure is too high, and causes the generation of the accident of blowing out, and is the high-risk hidden danger of traffic accidents.
Summary of the invention
The purpose of this utility model is to provide a kind of for the deficiency that solves above-mentioned technology, can make the tire internal air pressure remain on the tire puncture preventing valve nozzle cap of normal state automatically
In order to achieve the above object, the tire puncture preventing valve nozzle cap that the utility model is designed, it comprises the cap body, cap body one end is for connecting circular hole, connect the circular hole inboard and be provided with linkage structure, the bottom circle centre position that connects circular hole is provided with the valve inside venting post of projection, and valve inside venting post circle centre position is provided with the ventilation through hole; Ventilation through hole and annular air outlet UNICOM, annular air outlet is connected with the pressure limiting sealing gasket is airtight, and pressure limiting sealing gasket rear portion is provided with the pressure limiting spring, and the pressure limiting spring is connected with the can regulate locking mechanism, the can regulate locking mechanism is connected the other end of cap body, and this end is provided with exhaust port.Can regulate locking mechanism afterbody is connected with pressure-display device, can directly show the pressure index of pressure limiting spring.Connect the bottom of circular hole, can be provided with the valve cock sealing gasket, to prevent tire puncture preventing valve nozzle cap and the tyre valve core jointing phenomenon that leaks air.Linkage structure is arranged on the worm structure that connects circular-hole internal-wall, is fit to be connected with most tyre valve core.The can regulate locking mechanism can be a locking nut.
The resulting tire puncture preventing valve nozzle cap of the utility model; in the protection tyre valve core; may command tire internal air pressure; when tire pressure surpasses the safety pressure scope; gas in the release tire that can be automatic and suitable; alleviate the tire inner high voltage, remain within the safety range, effectively prevent to cause blowing out the accident generation owing to tire pressure is too high to guarantee tire pressure.Simultaneously, this tire puncture preventing valve nozzle cap has characteristics such as simple in structure, convenient and safe.
Description of drawings
Fig. 1 is present embodiment 1 structural representation;
Fig. 2 is present embodiment 2 structural representations.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, the tire puncture preventing valve nozzle cap that present embodiment is described comprises cap body 1, and cap body 1 one ends connect circular hole 12 inboards and are provided with linkage structure 2 for connecting circular hole 12, and this linkage structure 2 is arranged on the female thread structure that connects circular hole 12 inwalls.The bottom circle centre position that connects circular hole 12 is provided with the valve inside venting post 3 of projection, and valve inside venting post 3 circle centre positions are provided with ventilation through hole 5; Ventilation through hole 5 and annular air outlet 6 UNICOMs, annular air outlet 6 and 7 airtight connections of pressure limiting sealing gasket, pressure limiting sealing gasket 7 rear portions are provided with pressure limiting spring 8, pressure limiting spring 8 is connected with the can regulate locking mechanism, this can regulate locking mechanism 9 is locking nuts, locking nut is threaded on the cap body 1 by tire puncture preventing valve nozzle cap inside, and exhaust uropore 11 is arranged on this locking nut.Connect the bottom of circular hole 12, can be provided with valve cock sealing gasket 4, to prevent tire puncture preventing valve nozzle cap and the tyre valve core jointing phenomenon that leaks air.
During use, at first the tire puncture preventing valve nozzle cap is connected on the valve inside by linkage structure 2 internal threads, seal by 4 pairs of valve inside joints of valve cock sealing gasket, again by valve inside venting post, depress valve inside, emit the tire internal pressure, gas arrives annular air outlet 6 by ventilation through hole 5 in the tire, is sealed by pressure limiting sealing gasket 7.Pressure limiting sealing gasket 7 is that the pressure by pressure limiting spring 8 comes annular air outlet 6 is sealed, and the pressure size of pressure limiting spring 8 is to control setting by can regulate locking mechanism 9 locking nuts of afterbody.When the tire internal air pressure surpasses setting safety pressure value, pressure limiting sealing gasket (7) just comforter batt internal air pressure backs down, and gas is discharged in the atmosphere by exhaust port 11, thereby lowers the air pressure in the tire, guarantee that tire pressure remains within the setting pressure scope, effectively prevents to blow out.
Embodiment 2
As shown in Figure 2, the tire puncture preventing valve nozzle cap that present embodiment is described, its described can regulate locking mechanism 9 is provided with pressure-display device 10, and exhaust port 11 is provided with on the cap body 1, pressure limiting sealing gasket 7 is a ball plug.
