Abstract
The utility model relates to a two-way inflating device which mainly solve the problems that the existing inflating device can only inflate, the existing inflating device applies work when a rod is pressed, and the existing inflating device does idle work when the rod is pulled upwards. The utility model causes a piston in a barrel body to be composed of an upper piston and a lower piston, and the upper part and the lower part of one side of the barrel body are respectively provided with an air inlet valve. The upper part and the lower part of the other side of the barrel body are respectively provided with an air outlet valve, and an air conduit is arranged between two air outlet valves. An inflator type selector valve is arranged on the air conduit and is connected with a high pressure barrel. The utility model can all apply work and inflate whatever an inflating rod is pressed downwards or pulled upwards, and the work efficiency is improved.
Description
The utility model relates to a kind of inflator, particularly a kind of bidirectional inflating device.
At present, existing inflator (as bicycle pump etc.) all can only unidirectionally inflate basically, promptly can only when pressing down, could inflate by the inflation bar, can only be merit in vain and inflate when drawing on the bar, so just greatly influence working efficiency, increased people's labor intensity.
The purpose of this utility model be to provide a kind of the inflation bar press down or on draw the bidirectional inflating device of Shi Junneng acting, thereby increase work efficiency, alleviate people's labor intensity.
The purpose of this utility model is achieved in that it includes cylindrical shell 11, inflation handle 21, inflation bar 9, leg 20 and piston.The inflation piston that is arranged on inflation bar 9 bottoms is made of jointly upper piston 13 and lower piston 14; A suction valve 1 and 2 are respectively established in side top and the bottom at cylindrical shell 11, respectively establish a gas outlet valve 3 and 4 in the opposite side top and the bottom; Be provided with air pipe 18 between gas outlet valve 3,4, air pipe is provided with an inflator model selection valve 10, and this valve and high pressure cylinder 17 join.
Above-mentioned said inflation handle 21 constitutes the formula of living of rolling by a spin in it with inflation bar 9 and is connected.
Above-mentioned said leg 20, its pin are stepped on and are presented an angle of inclination between face and the base plate, and its top constitutes dismountable flexible connection with cylindrical shell 11.
The top of above-mentioned said cylindrical shell 11 also is provided with an oil groove 6, and its center is provided with rubber seal 22 with the junction point of inflation bar 9.
Advantage of the present utility model is simple in structure, and is easy to operate, improved charging efficiency, alleviated people's labor intensity.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation (omitted inflation handle 21) of the utility model when being used for bicycle pump.
Fig. 2 is the sectional structure schematic representation of the inflation handle 21 of Fig. 1 top.
Fig. 3 is the sectional structure schematic representation of the suction valve 1,2 among Fig. 1.
Fig. 4 is the sectional structure schematic representation of the inflator model selection valve 10 among Fig. 1.
Structure shown in the above accompanying drawing is embodiment of the present utility model.
1,2 is suction valve among the figure, and they only allow air to enter inflator inside from the inflator outside, do not allow air to overflow outside the tube.3,4 is gas outlet valve, and its working principle is opposite with suction valve 1,2, and they only allow air expelling tube external body in the tube, do not allow air to be entered by tube outward.Their outlet side links to each other with air pipe 18, and air is imported into the two ends of inflator model selection valve 10 through air pipe 18, and air is entered in the high pressure cylinder by the steam outlet pipe on the valve 10 at last.The tracheae that is connected by high pressure cylinder lower end is discharged from valve again.5 is rubber sealing ring, and its effect is to prevent that air from being overflowed by the slit between metallic rod 9 and the air cylinder cover.6 is oil groove, and lubricant oil can make between rubber sealing ring 5 and the metallic rod 9 and keep good lubricating effect, in order to avoid friction excessively heats up, fusing rubber band 5 reduces its sealing effect.7 is the rubber sealing ring snare, and as can be seen from the figure rubber sealing ring is bumped into wherein.Again the rubber sealing ring snare is screwed in air cylinder cover 8.Design is for the ease of changing rubber sealing ring 5 like this.Much more only 8 is air cylinder cover, and general inflator has, to have designed an oil groove.9 are the inflation metallic rod, and its end has screw thread, is used for upper handle 21.The other end has a baffle plate 23, and the following trifle metallic rod of baffle plate also has screw thread, and its effect is a fixed piston 13,14.Earlier a slice metal washer 24 is established during assembling into, establish successively into upper piston 13, thick metal washer 25, lower piston 14, metal washer 24, screw on hold-doun nut 15 again.10 is inflator model selection valve, and available screw-driver is regulated, and represents to have only when arrow points ▲ symbol and upwards draws and could inflate; Point to
In time, represented only could inflate to pressing down; Point to
The time represent upwards to pull to down push away all inflatable.11 is cylindrical shell, and cylindrical shell respectively is drilled with the hole of two symmetries up and down, and these holes are used for installing four valves (1,2,3,4).Also be drilled with two holes below cylindrical shell 11, these two holes are used for installing inflator pin 20.The 12nd, spring plays cushioning effect.13 is upper piston.14 are lower piston (going up lower piston also can be connected as a single entity).15 is a chain for binding criminals cap.17 is high pressure cylinder.18 is air pipe.The 19th, the inflation folder, its energy vertical motion can hold tighter.20 is detachable movable leg.21 is handle, can push away and can draw, not fragile, and the tiltable several angle.22 is the seal oil circle, prevents that lubricant oil from missing.23 for being provided with the baffle plate of piston and spring.24,25 be metal washer.26 are turning joint, are used for connecting inflator pin 20 and cylindrical shell 11.
The utility model as the working principle of pump is:
Slam inflator pin 20, gas folder 19 is clipped on the valve inside, and during pull-up handle 21, metallic rod 9 drives two pistons and moves upward, because outwards exhaust of suction valve 1, so at this moment piston 13 just can be compressed into high pressure cylinder 17 by gas outlet valve 3 with the air of top in the inflator.Because gas outlet valve 4 does not allow air to enter in the tube, so in this movement process, piston can suck the inflator bottom by suction valve 2 with outside air.Spring 12 contacts with air cylinder cover 8 when the top is arrived in piston motion, has played the effect of damping, thereby has protected inflator injury-free.When pushing handle 21, metallic rod 9 drives piston and moves downward, because outwards exhaust of suction valve 2, so at this moment piston 14 just can be compressed into high pressure cylinder 17 by gas outlet valve 4 with the air of below in the inflator.Because gas outlet valve 3 does not allow air to enter in the tube, so in this movement process, piston can suck inflator top by suction valve 1 with outside air.Can finish inflation and so forth.
