Abstract
The utility model provides a tire overpressure explosion preventer, which belongs to the vehicle pneumatic tire field. The utility model is mainly characterized in that an inner tube combining part is arranged at the air inlet end of a vent pipe, an air releasing hole is arranged on the pipe wall of the vent pipe, and a ball valve, a compression spring and an adjustable spring holder are arranged in the vent pipe, during the vehicle process and when the air pressure in the tire exceeds the limit, the air can be exhausted and the pressure can be released automatically, the tire movement under the safe air pressure is ensured, and the occurrence of the tire explosion accident caused by the over pressured tire is better avoided.
Description
Technical field
The utility model belongs to the vehicle body fittings field, relates to air-inflation tyre, is specifically related to a kind of tire overvoltage explosion-proof apparatus.
Background technology
Existing Pneumatic vehicle tire, as motor tire, its structure comprises: cover tire, the inner tube of a tyre, wheel rim, the charging valve mouth that combines with the inner tube of a tyre etc.Automobile is in the environmental conditions of load-carrying, weather sweltering heat, long-distance running, the heat that the long-time friction in tire and road surface is produced is heated tire, inner tube of a tyre air sharply expands, increased pressure, the easy fault of blowing out after the tire inner air pressure goes beyond the limit, cause traffic accident, work the mischief for vehicle, driver and conductor's lives and properties.
The utility model content
The designer finds that the overvoltage accident of blowing out easily takes place existing motor tire in life and work, through exploratory experiment, purpose is to provide a kind of tire overvoltage explosion-proof apparatus, through existing tire is improved, can avoid the tire overvoltage accident of blowing out preferably.
Technical solution adopted in the utility model is a kind of tire overvoltage explosion-proof apparatus of design, its structure comprises: breather pipe, be arranged on breather pipe air inlet end with inner tube of a tyre conjunction, expose at breather pipe on the tube wall of tire and offer air bleed hole, in the breather pipe of air bleed hole upstream, ball valve is set, the adjustable spring seat is set in the breather pipe of air bleed hole downstream side, between ball valve and spring perch, is connected with compression spring.
Also dust cap is set at the end of breather pipe end.
After this tire overvoltage explosion-proof apparatus entrucking of the present utility model is used, vehicle is in operation process, after the tire inner air pressure went beyond the limit, overpressure air forced ball valve to be opened automatically, discharged release of pressure automatically from air bleed hole, after the tire inner air pressure is tending towards normally, ball valve is the effect SELF CL of spring by compression, ensures that tire turns round under safety air pressure, thereby avoids tire to take place because of the overvoltage of the being heated accident of blowing out preferably, improve the tyre in operation safety, guarantee personal safety as well as the property safety.
This tire overvoltage explosion-proof apparatus of the present utility model is applicable to that various self-propelled vehiclees, the transformation of non-power-driven vehicle air-inflation tyre apply, and uses at heavy goods, passenger vehicle especially.
Description of drawings
Fig. 1 represents the structure and the assembling scheme drawing of the utility model tire overvoltage explosion-proof apparatus.
The specific embodiment
In conjunction with the accompanying drawings and embodiments, further specify the concrete structure of the utility model tire overvoltage explosion-proof apparatus, its feature and advantage are clearer.
The embodiment 1 of the utility model tire overvoltage explosion-proof apparatus is applicable to truck conspicuity marking, non-automotive applications.Referring to Fig. 1, its structure comprises: breather pipe 1, adopt L shaped copper pipe, adopt the conjunction that has the tire charging valve mouth and the inner tube of a tyre now with inner tube of a tyre conjunction 2, be arranged on the inlet end of breather pipe 1, expose at breather pipe on the tube wall of tire and offer air bleed hole 3, in the breather pipe 1 of air bleed hole 3 upstreams, ball valve 4 is set, spring perch 6 is set in the breather pipe of air bleed hole 3 downstream side, between ball valve 4 and spring perch 6, compression spring 5 is set.Wherein spring perch 6 adopts the adjustable spring seat, and spring perch 6 is threaded with breather pipe 1, offers in the bottom of spring perch 6 and transfers the groove (not shown).Also dust cap 7 is set at the end of breather pipe 1 end.
During installation,, be assemblied on the tire,, set up spring perch by the examination inflation by the combination of the charging valve mouth and the inner tube of a tyre with charging valve mouth symmetry.
The embodiment 2 of the utility model tire overvoltage explosion-proof apparatus is applicable to cyclecar, non-power-driven vehicle application.Referring to Fig. 1, its structure comprises: in the structure of embodiment 1, breather pipe adopts the straight tube copper pipe.
Claims (2)
1. tire overvoltage explosion-proof apparatus, comprise breather pipe, with inner tube of a tyre conjunction, it is characterized in that being arranged on the air inlet end of breather pipe with inner tube of a tyre conjunction, expose at breather pipe on the tube wall of tire and offer air bleed hole, in the breather pipe of air bleed hole upstream, ball valve is set, the adjustable spring seat is set in the breather pipe of air bleed hole downstream side, between ball valve and spring perch, compression spring is set.
2. tire overvoltage explosion-proof apparatus as claimed in claim 1 is characterized in that also at the end of described breather pipe end dust cap being set.
