Abstract
The utility model relates to a two-way inflating inflator, wherein, the air cylinder (8) of the inflator is provided with a piston (7) inside; a piston rod (6) extends out from an upper end cap (11) to be connected with a piston driving mechanism; moreover, a seal component (12) is arranged between the piston rod (6) and the upper end cap (11); both the upper end cap (11) and the lower end cap (10) of the air cylinder (8) are provided with air inlet valves (5) and exhaust valves (1); the two exhaust valves are respectively connected with an air tank (4) through connecting tubes (2), while the air tank (4) is connected with an air tube (3); moreover, the air inlet valves (5) and the exhaust valves (1) are gas one-way valves. When the piston moves up and down, the inflator is in inflating state all the time, thereby realizing two-way inflating.
Description
Affiliated technical field
The utility model relates to a kind of pump of bidirectional inflating, belongs to tyre inflation electrician testing tool technology field such as bicycle, motorcycle, electric motor car.
Background technique
At present, the principal mode of pump has: the one, and plain edition comprises pull bar articulated and scyewed joint formula; The 2nd, the gas tank type comprises side storage type, following storage type, internal storage type.Use checking through reality, relatively require great effort when the former uses, the latter obviously is better than the former, the characteristics of gas tank type pump are inflation pressure height, brisk laborsaving, but owing to the traditional design structure that generally adopts, can only inflate by single stroke, charging efficiency is low, and volume big, carry inconvenience.
Summary of the invention
The purpose of this utility model is to propose a kind of charging efficiency height, little, the portable bidirectional inflating pump of volume.
The technological scheme that its technical problem that solves the utility model adopts is:
Placed piston in the inflator of pump, piston rod stretches out from upper end cap, is connected with piston drive mechanism, and between piston rod and upper end cap black box has been installed; On the upper end cap of inflator and lower end cap suction valve and outlet valve have been installed all, two outlet valves are connected with gas tank by connecting leg respectively, and gas tank is connected with steam outlet pipe; Suction valve and outlet valve are the gas unidirectional valve.Piston drive mechanism driven plunger linear reciprocating motion in inflator by the effect of Aspirating valves and outlet valve, is finished air-breathing and exhaust.When piston when going up shifting movement bottom, inferior part of the cylinder block forms negative pressure, it is air-breathing that extraneous gas impels Aspirating valves to open, and the bottom outlet valve is closed; This moment, the Aspirating valves on piston top was in closed condition under the effect of air pressure, and the gas after the supercharging enters in the gas tank exhaust valve opening on top, and vice versa.
The beneficial effects of the utility model are:
(1) because piston up-down all is in gas replenishment process, and existing pump can only unidirectionally be inflated, and therefore charging efficiency of the present utility model improves greatly.
(2) owing to adopted bidirectional inflating, efficient increases, so under the situation that can satisfy usage requirement, reduce the volume of pump, the volume that has therefore overcome existing pump is big, carry inconvenient shortcoming.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is embodiment's 1 an of the present utility model plan view.
Fig. 3 is embodiment's 2 an of the present utility model plan view.
Among the figure, 1. outlet valve 2. connecting tubes 3. steam outlet pipes 4. gas tanks 5. suction valves 6. piston rods 7. pistons 8. inflators 9. foot treadles 10. lower end caps 11. upper end caps 12. black boies 13. connecting rods 14. cranks 15. rocking arms 16. bearings 17. rocking bars
Be schematic diagram of the present utility model among Fig. 1, respectively connected outlet valve (1) and suction valve (5) on the inflator (8) of the both sides of piston (7), outlet valve (1) is connected with gas tank (4) by connecting tube (2).
In embodiment illustrated in fig. 21, placed piston (7) in the inflator (8) of pump, piston rod (6) stretches out from upper end cap (11), is connected with piston drive mechanism, and between piston rod (6) and upper end cap (11) black box (12) has been 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); Suction valve (5) and outlet valve (1) are the gas unidirectional valve.Piston drive mechanism is made of connecting rod (13), crank (14) and rocking arm (15), wherein connecting rod (13) is connected with piston rod (6), like this, crank (14), connecting rod (13) and piston rod (6) have constituted slidercrank mechanism, when the hand arm (15) that shakes impels crank (14) when rotation, piston (7) does reciprocating linear motion in inflator, by the effect of Aspirating valves (5) and outlet valve (1), finishes air-breathing and exhaust.When piston (7) when going up shifting movement bottom, inferior part of the cylinder block forms negative pressure, it is air-breathing that extraneous gas impels the Aspirating valves of bottom to open, and the outlet valve of bottom is closed; This moment, the Aspirating valves on piston top was in closed condition under the effect of air pressure, and the gas after the supercharging enters in the gas tank exhaust valve opening on top, and vice versa.Therefore, piston up-down all is in gas replenishment process, has realized the bidirectional inflating of pump.
In embodiment illustrated in fig. 32, piston drive mechanism is made of connecting rod (13), bearing (16) and rocking bar (17), wherein connecting rod (13) is connected with piston rod (6), like this, rocking bar (17), connecting rod (13) and piston rod (6) have constituted slider-rocker mechanism, therefore, lift when pressing rocking bar (17), piston (7) is made downward and downward linear reciprocating motion in inflator, thereby has realized the bidirectional inflating of pump.
During use, can extract foot treadle of the present utility model (9) out, inflate with foot-operated firmly foot treadle (9); Also this pump can be fixed in bicycle, motorcycle, the electric motor car supporting use.
