Abstract
The utility model discloses a tire inflating tool, which is characterized in that the inflator body is divided into upper and lower two parts by a partition plate arranged inside; the upper half part is a gas inflation chamber, and the lower half part is a gas storage chamber. The partition plate is provided with a sealing device which only allows the gas to flow in single direction from the gas inflation chamber to the gas storage chamber. The partition plate is fixed at the bottom of the inflator body, and can be taken out of the inflator body for maintaining.
Description
The utility model belongs to inflatable tool, is specifically related to a kind of air storing type single tube pump with dividing plate.
Its gas storage chamber of pump of existing band gas storage chamber has following several form: set up gas holder outside the inflator stack shell separately; Connect one section in addition as gas storage chamber in inflator stack shell bottom; Utilize hollow piston rod to form gas storage chamber etc.Above form exists makes shortcomings such as inconvenience, cost is high, the easy corrosion of one-way valve damages and freeze.
The utility model proposes a kind of pump that directly utilizes the part of stack shell as gas storage chamber.Wherein being fixed in pump stack shell bottom, can only allowing the baffle plate device that gas unidirectional flows is to realize key point of the present invention.
Two kinds of concrete structures of the present utility model are illustrated in conjunction with the accompanying drawings.
Fig. 1 is that the seal arrangement on the dividing plate adopts the ox-hide leather cup, and base and stack shell adopt a kind of structural type when being welded to connect.
Fig. 2 for the seal arrangement on the dividing plate by O RunddichtringO and spring steel ball check valve constitute jointly, a kind of structural type when base is threaded with the stack shell employing.
Handle among the figure (1), stack shell (2), piston (3), inflate chamber (4), baffle plate device (5), seal arrangement (6), gas storage chamber (7), base (8), seal washer (9), the sebific duct of giving vent to anger (10).
Handle during inflation (1) drive piston (3) moves up and down air is pressed into gas storage chamber (7).Seal arrangement (6) on the baffle plate device (5) only allows gas by inflating chamber (4) to gas storage chamber (7) one-way flow.Seal arrangement (6) can be formed separately or be sealed by O type rubber seal and add the spring steel ball check valve in addition and constitute jointly by ox-hide leather cup, V-type rubber seal, type rubber seal.Slide relative does not take place with stack shell (2) inwall in seal arrangement during use (6), and is therefore not fragile.Baffle plate device (5) is fixed in the bottom of stack shell (2), can adopt means of fixation such as Fig. 1, Fig. 2 respectively according to the difference of inflator structure.Baffle plate device (5) can take out from stack shell (2) easily, in order to maintenance.
The advantage of this inflator is: simple in structure, easy to make, cost is low, in light weight, good looking appearance, check valve is not fragile and freeze. Existing common single tube inflator does not change any part or only does the minute quantity change, just can implement the present invention behind the baffle plate device of packing into.
Claims (4)
1, a kind of inflatable tool, by handle (1), stack shell (2), piston (3), inflate chamber (4), seal arrangement (6), gas storage chamber (7), base (8), form, it is characterized in that inflating that chamber (4) and gas storage chamber (7) are cut off by baffle plate device (5) makes its shared stack shell (2).
2,, it is characterized in that being equipped with on the baffle plate device (5) and can only make gas from inflating the seal arrangement (6) of chamber (4) to gas storage chamber (7) one-way flow by the described inflatable tool of claim 1.
3, by the described inflatable tool of claim 1, it is characterized in that baffle plate device (5) is fixed on the bottom of stack shell (2), can from stack shell (2), take out after the dismounting.
4,, it is characterized in that seal arrangement (6) is made up of separately ox-hide leather cup or V-type rubber seal or O type rubber seal or adds that by O type rubber seal one-way valve constitutes jointly by claim 1 or 2 described inflatable tools.
