Abstract
The utility model relates to a built-in type tyre auto-inflation pump characterized in that the auto-inflation pump is positioned in the inner tyre. The utility model can automatically supply air to the tyre at ant time with the operation of the tyre in order to solve the problem of natural air leaking of the tyre. The inner portion of the auto-inflation pump is provided with a return spring used for sucking the air into the pump. When the auto-inflation pump is stressed by the external pressure, the air in the pump can be pressed into the inner tyre whose pressure intensity is relatively smaller. When the pressure intensity of the inner tyre is close to the pressure intensity in the auto-inflation pump, the auto-inflation pump can automatically stop working. Meanwhile the tyre provided with the utility model can still use the traditional inflation method to conduct inflation.
Description
The utility model relates to the built-in automatic inflation pump of a kind of tire, and at present, known inflatable tire makes the problem of inflatable tire ubiquity gas leakage because of reasons such as its manufactured materials, processing technology, air intake valves.In order to solve the problem of tire flat, the utility model provides a kind of tire built-in automatic inflation pump, and this tire can solve the problem of tire flat with this at any time automatically for tire carries out tonifying Qi with built-in automatic inflation pump.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is front view and the part sectional view of the utility model tire with built-in automatic inflation pump.
Fig. 2 is the birds-eye view of the utility model tire with built-in automatic inflation pump.
Fig. 3 is the A-A section-drawing of the utility model tire with built-in automatic inflation pump.
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The inflation pump pump housing [2] outside be connected with air inlet valve [1], check valve [3], inflation pump base [5], and the inside of the inflation pump pump housing [2] is provided with retracing spring [4].Air inlet valve [1], the inflation pump pump housing [2], retracing spring [4], the inflation pump pump housing [2], inflation pump base [5] are linked in sequence, and check valve [3] is connected the both sides of the inflation pump pump housing [2].The air intake valve of the common inner tube of a tyre is cut, and the bonding location [7] that then two terminations of the inner tube of a tyre [6] is bonded in the inflation pump pump housing [2] two ends is respectively located.
After the inner tube of a tyre [6] gas leakage, the diameter of the inner tube of a tyre [6] will be less than the diameter of the inflation pump pump housing [2], this moment is along with the running of tire, the inflation pump pump housing [2] will be subjected to the effect of retracing spring [4] and air will be inhaled in people's inflation pump pump housing [2] by air inlet valve [1], and then air be pumped in the inner tube of a tyre [6] by check valve [3] because of the effect of tire heavy burden pressure.When the air pressure in the inner tube of a tyre [6] when air pressure in the inflation pump pump housing [2] equates, tire will quit work with built-in automatic inflation pump.And when the inner tube of a tyre [6] when leaking gas once more, tire will carry out tonifying Qi for tire automatically with built-in automatic inflation pump.Simultaneously, tire of the present utility model being installed still can use common inflation mode to put on the air.
Claims (5)
1. the built-in automatic inflation pump of tire on a spherical hollow inflated rubber pump pump housing [2], is connected with air inlet valve [1], check valve [3], inflation pump base [5], and is provided with retracing spring [4] in the inflation pump pump housing [2].
2. the built-in automatic inflation pump of tire according to claim 1, it is characterized in that air inlet valve [1], the inflation pump pump housing [2], retracing spring [4], the inflation pump pump housing [2], inflation pump base [5] are linked in sequence, check valve [3] is connected the two ends of the inflation pump pump housing [2].
3. the built-in automatic inflation pump of tire according to claim 1 is characterized in that air inlet valve [1] is conventional general air intake valve, and check valve [3] is the rubber elongated tubular.
4. the built-in automatic inflation pump of tire according to claim 1 is characterized in that tire is bonded in bonding location [7] with the built-in automatic inflation pump pump housing [2] and the inner tube of a tyre [6] and locates.
5. according to claim 1,2,3, the built-in automatic inflation pump of 4 described tires, it is characterized in that installing tire and equally also can adopt the conventional aerating mode to carry out aerating by air inlet valve [1] with the tire of built-in automatic inflation pump.
