Abstract
The utility model discloses a pedal inflating-pump, belonging to the field of inflating-pumps. The utility model is characterized in that a pendulum rod (10) and an air barrel (2) are crossed and are respectively hinged to a body frame (4); torsion spring (1) are wound round both ends of a pin axle (6) hinging the body frame (4) and the pendulum rod (10), and are respectively act on the body frame (4) and the pendulum rod (10). With the utility model, a push rod (14) of the air barrel (2) is the two-force rod, and as a result, a leather-cup can not be tilted inside the cavity of the air barrel (2). The utility model has the advantages of labor-saving, high efficiency, long service life and uneasy abrasion of the leather-cup.
Description
The utility model relates to a kind of air pump, exactly is foot-operated air pump.
Existing foot-operated air pump mainly is made up of frame, reduction torsion spring and the fork, inflator, the foot-operated institute that constitute portable guide-bar mechanism.Because fork and inflator reduction torsion spring are on the bearing pin that is connected frame, inflator, fork, act between the cylindrical shell of frame and inflator, so in the process of inflating, the push rod of inflator is except that axially loaded, also bear certain bending moment, must cause leather cup crooked in cylindrical shell, not only leather cup is easy to wear, and the operation effort.
The purpose of this utility model is intended to overcome the deficiency in the prior art, and a kind of modified model foot-operated air pump of rapid operation is provided.
In order to achieve the above object, technical solution of the present utility model mainly is made of frame, fork, inflator, foot-operated, fork reduction torsion spring and foot-operated reduction torsion spring, it is characterized in that being hinged on the frame respectively after fork and the inflator intersection; The fork reduction torsion spring is on the bearing pin of hinged frame and fork, and two acts on respectively on frame and the fork.Because in technical solution described in the utility model, the push rod of inflator is two power bars, therefore in the process of inflating, leather cup is straight in air cylinder body, and is not askew not oblique.
It is not easy to wear that compared with the prior art the utility model has rapid operation, pump gas efficient height, leather cup, the advantage of long service life.
Below in conjunction with drawings and Examples the utility model is made more progressive detailed description, in the hope of further understanding above-mentioned purpose of the present utility model and effect.
Description of drawings:
Fig. 1 is the structural representation of a kind of specific embodiments of the utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment:
See figures.1.and.2, two ears (12) are established in both sides (4) one of the rectangle frames of being made by sheet metal, with hinged two forks of bearing pin (6) (10), go up around a torsion spring (1) at bearing pin (6) again, the center double end of torsion spring (1) acts on the frame (4), the both sides single head of torsion spring (1) acts on respectively on two forks (10), and under the effect of torsion spring (1) elastic force, fork (10) can rotate around bearing pin (6) inhour; On the center line of rectangle frame (4), the right side of two ears (12) establishes an ear (13) again, with the hinged inflator of bearing pin (7) (2), this articulating point is located on the shaft axis of inflator (2); One of will ride (3) is hinged with the push rod (14) of inflator (2) with bearing pin (11), and the other end of foot-operated (3) is hinged with bearing pin (9) and two forks (10), and makes two forks (10) parallel; Bearing pin (9) is gone up around a torsion spring (8), and the center double end of torsion spring (8) acts on foot-operated (3), and the both sides single head acts on respectively on two forks (10), and under the effect of torsion spring (8) elastic force, foot-operated (3) can clockwise rotate around bearing pin (9).
See figures.1.and.2, in rectangle frame (4) other end, establish an ear (15) in the heart, with the hinged hook (5) of bearing pin (16), can hook the middle part of bearing pin (9), to reach the purpose of drawing in when leaving unused with linking up with (5).
Below in conjunction with accompanying drawing, working principle of the present utility model is done one simply introduce.
Referring to Fig. 1, apply a downward power for foot-operated (3), inflator (2) and fork (10) are respectively around bearing pin (6) and (7) rotation clockwise, ride (3) one around the rotation of bearing pin (9) inhour, push the push rod of inflator (2) (14) to calm the anger in the tube to when bearing pin (11) inhour is rotated in the other end of foot-operated (3), pressurized air is discharged by tracheae (17), enters the tire that needs qi of chong channel ascending adversely, promptly finishes exhaust process.When the power on foot-operated when acting on (3) disappeared, under the effect of torsion spring (1) and (8) elastic force, each component movement process was promptly finished breathing process with above-mentioned opposite.
Claims (2)
1, a kind of foot-operated air pump, mainly constituted, it is characterized in that being hinged on respectively on the frame (4) after fork (10) and inflator (2) intersect by frame (4), fork (10), inflator (2), foot-operated (3), fork reduction torsion spring (1) and foot-operated reduction torsion spring (8); Fork reduction torsion spring (1) is on the bearing pin (6) of hinged frame (4) and fork (10), and two acts on respectively on frame (4) and the fork (10).
2, a kind of foot-operated air pump according to claim 1 is characterized in that establishing an ear (15) at the center of rectangle frame (4) other end, with the hinged hook (5) of bearing pin (16).
