Description
Technical field
The present invention mainly discloses a kind of flexible pipe combination apparatus, refers to a kind of flexible pipe combination apparatus that is used in mini inflating pump especially.
Background technique
Because various countries, whole world living standard generally improves, therefore relatively also pay attention to recreation in recent years, stop two days enforcement along with week; People increase many leisure times, therefore, utilize the number of being engaged in leisure, tourism and motion these holidaies that the trend that increases is rapidly more arranged; Be engaged in stress-relieving activity and can arrive the open air; Only instrument promptly is a bicycle, and therefore, the pump during bicycle is equipped with is the indispensable carry-on articles of bicycle knight especially.
Like No. 2007/0148023 " PUMP " patent of Patent Application No. case, be the previous invention of claimant, its this block alternative is engaged in two positioning parts, reaches to open to use or the use of collection.When using, can produce with respect to the displacement of handle bar by movable block and inflate effect; After finishing using, this handle body income handle is got final product.The present invention folds back ten minutes minimizing and takies volume, seems quite compact.
Existing mini inflating pump is because whole volume is little; So connect when establishing cranked tire valve at the head of mini inflating pump because the volume of mini inflating pump is little and its head and handle body between be fixed structure, and can't be movable relatively; So operate in the process that the handle to-and-fro motion inflates the user; Can let the mini inflating pump head rock, and the head of mini inflating pump rock and just can have influence on inflation in the process of inflating, light then cause the phenomenon of gas leakage; Heavy then easily because rocking of hand lets head driven wheel nausea mouth synchronization motion, and cranked tire valve continues to receive pullling of head and causes the impaired even fracture of cranked tire valve easily.
And another kind of hose type connects the mini inflating pump of charging air inlet and pump connecting rod; Like No. 200420068511.9 " mini inflating pump " patent of People's Republic of China's number of patent application case; Be the previous creation of claimant; Its setting by holding device has the function that conveniently grips, and be connected valve the filling head it establishes the end that a flexible pipe can be taken in holding device, and the other end that stage operation cylinder all can superimposed income holding device.
Aforementioned mini inflating pump has flexible pipe and connects filling head and joint; And because must keep the airtight relation that gas is not leaked between flexible pipe and connecting rod, the pipe close of flexible pipe will be connected to the connecting rod inwall very closely, so flexible pipe can produce frictional force in the process of pull; But an only sheathed clasp is incorporated into flexible pipe on the pipe close between the flexible pipe of existing mini inflating pump and the pipe close; Flexible pipe perhaps use adhesive to engage, so when flexible pipe will spur pipe close and in connecting rod, relatively moves, can be because will overcome frictional force and the enough pulling force of needs of pipe close and connecting rod; And clasp is fixed the strength deficiency of flexible pipe; Make when the user spurs the filling head that can gradually flexible pipe be pulled away from pipe close, last flexible pipe just can break away from this pipe close and can't re-use.
Moreover when flexible pipe drew back, the end that flexible pipe has a pipe close can be butted on the opening inwall of this joint; Make flexible pipe to produce friction with the internal face of joint; And then make the flexible pipe attenuation and have with pipe close breaks away from and possibly take place, for the problems referred to above, urgently await the necessity that improves.
Because the disappearance of above-mentioned existing structure, the inventor is a flexible pipe combination apparatus of inventing out a kind of mini inflating pump, and it can overcome all shortcomings of above-mentioned existing structure.
