Abstract
The utility model discloses an inflator, which comprises an inflator body, wherein, the lower end of the inflator body is connected with an air drum; the connection part of the inflator body and the air drum is respectively provided with an air input spacer block provided with an air inlet and an air drum spacer block; a sealing ball for sealing the air inlet of the air input spacer block is arranged between the two spacer blocks; a restoring spring is arranged between the sealing ball and the air drum spacer block. Because the air drum can be made of pipe material, the utility model can reduce the investment of the processing equipment.
Description
The utility model relates to a kind of pump, relates in particular to the manual pump that has tympanites.
The pump of existing band tympanites all is on the pump next door tympanites to be installed, and makes when inflating for wheel laborsaving.This tympanites is usually all by the stretching single forming.Make that like this disposable apparatus investment is big when producing, product is also wordy attractive in appearance.
The purpose of this utility model provides a kind of pump, and it is simple in structure, and less demanding to equipment can reduce equipment investment greatly.
The purpose of this utility model is achieved in that a kind of pump, include the pump assembly, be connected with a tympanites in the lower end of pump cylinder, joint at pump cylinder and tympanites is equipped with air inlet spacer block and the enraged spacer block of bringing gas port into respectively, between these two spacer blocks, there is a ball sealer to be used to be sealed into suction port on the air bound piece, between ball sealer and the enraged spacer block Returnning spring is installed.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
With reference to the accompanying drawings, the lower end of pump cylinder (1) is connected with a tympanites (7) by modes such as screw-thread fit, one air inlet spacer block (2) is installed on pump cylinder (1), on air inlet spacer block (2), have suction port (3), suction port (3) is sealed by ball sealer (4), between ball sealer (4) and the enraged spacer block (6) Returnning spring (5) is installed, it makes ball sealer (4) seal the suction port (3) of air inlet spacer block (2) at ordinary times.
When needs are inflated, oppress ball sealer (4) from the pressurized air that pump is come, it is moved down, thereby suction port (3) is opened, pressurized air enters tympanites (7), and when pump did not produce pressurized air, ball sealer (4) resetted under the effect of Returnning spring (5), sealing suction port (3) makes that the pressurized air in the tympanites (7) can not spill.
Because tympanites can directly process with tubing, need not to use the method for stretch forming, so can significantly reduce the investment of process equipment.
Claims (1)
1. pump, include pump cylinder, the lower end that it is characterized in that pump cylinder is connected with a tympanites, at pump cylinder and enraged joint air inlet spacer block and the enraged spacer block of bringing gas port into is installed respectively, between these two spacer blocks, there is a ball sealer to be used to be sealed into the suction port of air bound piece, between ball sealer and the enraged spacer block Returnning spring is installed.
