Abstract
The utility model discloses a reciprocating bidirectional inflating pump comprising an air cylinder; the air cylinder is internally provided with a bidirectional valve piston dividing the air cylinder into an upper air cylinder and a lower air cylinder; the bidirectional valve piston is communicated with one end of a gas rod, and the other end of the gas rod passes through the lower end face of the air cylinder and is connected with a one-way check valve; the one-way check valve is connected with an inflating needle; the upper air cylinder is internally provided with an upper intake valve; and the lower air cylinder is internally provided with a lower intake valve. Compared with the prior art, when the air cylinder moves downwards, air enters from the lower intake valve, the upper intake valve is closed, and the air in the upper air cylinder is extruded to enter the gas rod from the bidirectional valve piston and then to charge air through the one-way check valve and the inflating needle; when the air cylinder moves upwards, air enters from the upper intake valve, the lower intake valve is closed, and the air in the lower air cylinder is extruded to enter the gas rod from the bidirectional valve piston and then to charge air through the one-way check valve and the inflating needle; and therefore, bidirectional charging is realized. The reciprocating bidirectional inflating pump has the advantages of simple structure, low manufacturing cost, high charging efficiency, small volume, convenient carrying, and the like.
Description
Technical field

Background technique
Present pump is the structure of common unidirectional pump usually, there is the low shortcoming of charging efficiency in this pump, in order to improve this situation, someone has made useful improvement, as application number is the pump that 200720033506.8 Chinese utility model patent discloses bidirectional inflating, in the inflator (8) of pump, placed piston (7), piston rod (6) stretches out from upper end cap (11), be connected with piston drive mechanism, and between piston rod (6) and upper end cap (11), black box (12) be installed; On the upper end cap (11) of inflator (8) and lower end cap (10) suction valve (5) and outlet valve (1) have been installed all, two outlet valves are connected with gas tank (4) by connecting tube (2) respectively, and gas tank (4) is connected with steam outlet pipe (3); And suction valve (5) and outlet valve (1) are the gas unidirectional valve.During piston up-down, all be in inflated condition, realized the bidirectional inflating of pump.Though above-mentioned patent can be carried out bidirectional inflating, but still has complex structure, fabricating cost height, and the bigger shortcoming of volume.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provide a kind of simple and reasonable, fabricating cost is low, volume is little, portable reciprocating type bidirectional pump tube.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of reciprocating type bidirectional pump tube, comprise inflator, be provided with the two-way valve piston in the inflator, the two-way valve piston is divided into upper cylinder and lower cylinder with inflator, and the two-way valve piston is communicated with an end of gas bar, and the other end of gas bar passes the lower end surface of inflator and is connected with one way stop peturn valve, one way stop peturn valve is connected with Aerating needle, in addition, be provided with upper inlet valve in the upper cylinder, be provided with lower inlet valve in the lower cylinder.
In order to obtain better technique effect, further technical measures also comprise:
Above-mentioned upper inlet valve is positioned at the upper-end surface of inflator, and lower inlet valve is positioned at the lower end surface of inflator and is set on the gas bar.
On the outer circumferential face of above-mentioned inflator handle is installed.
Above-mentioned one way stop peturn valve is connected with the inflator seat, and the inflation inlet of Aerating needle is positioned at the outside of inflator seat.
Compared with prior art, be provided with the two-way valve piston in the inflator of the present utility model, the two-way valve piston is divided into upper cylinder and lower cylinder with inflator, the two-way valve piston is communicated with an end of gas bar, the other end of gas bar passes the lower end surface of inflator and is connected with one way stop peturn valve, and one way stop peturn valve is connected with Aerating needle, in addition, be provided with upper inlet valve in the upper cylinder, be provided with lower inlet valve in the lower cylinder.The utility model is broken thinking set, mobile piston not, but promote inflator in use up and down, make the relative inflator motion of piston, when inflator moves down, the lower inlet valve air inlet, simultaneously upper inlet valve is closed, and the gas in the upper cylinder is extruded and advances air inlet pole from the two-way valve piston and inflate by one way stop peturn valve and Aerating needle; When inflator moves up, the upper inlet valve air inlet, simultaneously lower inlet valve is closed, and the gas in the lower cylinder is extruded and advances air inlet pole from the two-way valve piston and inflate by one way stop peturn valve and Aerating needle, thereby realizes the purpose of bidirectional inflating.This enforcement is novel have simple in structure, low cost of manufacture, the charging efficiency height, volume is little, advantage such as be easy to carry.
Description of drawings
Fig. 1 is the utility model embodiment's a structural principle schematic representation.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, figure grade explanation: inflator 1, upper cylinder 1a, lower cylinder 1b, two-way valve piston 2, gas bar 3, one way stop peturn valve 4, Aerating needle 5, upper inlet valve 6, lower inlet valve 7, handle 8, cylinder base 9.
Embodiment as shown in the figure, a kind of reciprocating type bidirectional pump tube, comprise inflator 1, be provided with two-way valve piston 2 in the inflator 1, two-way valve piston 2 is divided into upper cylinder 1a and lower cylinder 1b with inflator 1, two-way valve piston 2 is communicated with an end of gas bar 3, the other end of gas bar 3 passes the lower end surface of inflator 1 and is connected with one way stop peturn valve 4, and one way stop peturn valve 4 is connected with Aerating needle 5, in addition, be provided with upper inlet valve 6 in the upper cylinder 1a, be provided with lower inlet valve 7 in the lower cylinder 1b.
In order further to improve the using effect of present embodiment, the upper inlet valve 6 of present embodiment is positioned at the upper-end surface of inflator 1, and lower inlet valve 7 is positioned at the lower end surface of inflator 1 and is set on the gas bar 3.Upper inlet valve 6 and lower inlet valve 7 are arranged at the end can utilize the stroke of two-way valve piston in inflator to greatest extent, because if upper inlet valve 6 and lower inlet valve 7 are arranged on the inflator side, because the two-way valve position of piston can not exceed the position of upper inlet valve 6 and lower inlet valve 7, therefore, its stroke will inevitably be restricted, and reduces the charging efficiency of present embodiment.
