Abstract

The utility model relates to a double-head air taking pump. The double-head air taking pump is mainly composed of a machine seat, a swing rod, a cylinder, and a piston. The double-head air taking pump is characterized in that An air inlet valve and an air outlet valve are respectively arranged on the body end of the cylinder arranged on the top of the machine seat. Two ends of the piston in the cylinder are all provided with piston rings. Two pulley wheels are arranged on the middle parts of the piston rings. The swing rod in the machine seat can be driven by an outward pull motor through a belt to wind a movable point wheel to swing from left to right. Two pulley wheels are driven on the top of the swing rod, and the piston in the cylinder does reciprocating movement. The structure of the double-head air taking pump is simple. A crank rotates one circle of a vehicle, the cylinder can exhaust in a quadric mode. The secondary stability that a crank of the existing air pump rotates one circle, air is only be exhausted once is overcome. Electric energy is saved, and air taking speed is accelerated. The double-head air taking pump is suitable for making an air compressor.

Description

A kind of double end is got air pump

The utility model relates to a kind of air pump of getting, and is that a kind of double end is got air pump specifically.

Traditional air pump of getting generally has only a suction valve, a gas outlet valve, and a piston ring, crank rotates a circle, and can only inflate once, and therefore the efficient of this pump is low, and inflation is slow.

The purpose of this utility model is to improve traditional air pump of getting, and crank is rotated a circle, and inflates twice, gets the efficient and the aeration speed of air pump with raising.

The purpose of this utility model is this realization: at cylinder of support upper end design, each design of cylinder two ends has suction valve and gas outlet valve, and the piston two ends in cylinder are equipped with piston ring, constitute double-head piston.At the double-head piston middle part, be provided with two pulleys; In support, be provided with fork, one end of fork is fixed on the support bottom by fulcrum shaft, the other end is fixed in the middle of two pulleys of double-head piston, the fork middle part is provided with square groove, be provided with sliding shoes in the groove, be connected with crank on the sliding shoes, on the support wall, wherein an end is outside belt pulley and the stretching wall to crank by bearing fixing.Motor drives the crank rotation by belt, sliding shoes is moved up and down in the square groove of fork, and driving pendulum rod swings around fulcrum shaft, two pulleys are stirred on the top of fork, make double-head piston in cylinder, make the straight line back and forth movement, under the cooperating of cylinder two ends, finish double end and get airway dysfunction into and out of air valve.

Advantage of the present utility model: 1, simple in structure, only offer into and out of air valve at the cylinder two ends, with the equal ring installation in the two ends of piston, driving force is placed on the piston middle part, just can realize that crank rotates a circle, and twice the effect of supplying gas is easy to utilize; 2, because of crank rotates a circle, can supply gas for twice, former relatively air pump can be raised the efficiency one times, and aeration speed adds fast again; If 3 institute's air demands are certain, with this pump air feed, can save electric energy 30～50% than the former air pump of getting, inflationtime also can reduce 30～50%.

Introduce an embodiment below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the side view of Fig. 1.

With reference to accompanying drawing: in support (1), design has fork (2), be provided with square groove (3) at the middle part of fork (2), in square groove, design the sliding shoes (4) that can slide up and down, sliding shoes (4) is enclosed within crank (5) middle part, on the support wall, wherein an end is outside belt pulley and the stretching wall by bearing fixing at the two ends of crank; The lower end of fork (2) is fixed on the support bottom by fulcrum shaft (6), be provided with cylinder (7) at the support top, be equipped with suction valve (8) and gas outlet valve (9) at the cylinder two ends, in cylinder (7), be provided with piston (10), the two ends of piston (10) are equipped with piston ring (11), there are two pulleys (12), the top of fork (2) to wear the top of seat (1) in the design of the middle part of piston (10), are fixed between two pulleys (12) at double-head piston (10) middle part.Belt with the peripheral hardware motor during work is connected on the belt pulley of crank (5), driving pendulum rod (2) swings around fulcrum shaft (6), two pulleys (12) are stirred on the top of fork (2) makes piston make the straight line back and forth movement in cylinder, the suction valve and the gas outlet valve at cylinder two ends take turns to operate, and finish double end and get the gas task.

Claims
