Description
Technical field
The utility model relates to a kind of pump, and more particularly, it relates to a kind of manual pump.
Background technique
Water pump is the machinery of carrying liquid or making liquid supercharging.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to carry liquid to comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., also can carry liquid, gaseous mixture and the liquid containing suspended solids.The technical parameter of pump performance has flow, inhales journey, lift, air horsepower, water-horse power, efficiency etc.; Can be divided into the types such as volume water pump, vane pump according to different working principles.Displacement pump is to utilize the variation of its swept volume of a single chamber to carry out transferring energy; Vane pump is to utilize the interaction of rotary vane and water to carry out transferring energy.
Manual pump has accounted for a very large ratio in water pump, while back and forth shaking crank handle, by driving mechanisms such as axle, rocking arm, connecting rods, makes piston reciprocates with hand.In the time that piston is moved to the left, the pumping cylinder volume of right-hand member expands gradually, forms vacuum, and liquid backs down suction valve through casting at the suction passage on pump housing side from suction sleeve and enters cylinder body right-hand member.At one time, cylinder body left side, due to the compression of piston, backs down setting-out valve, and liquid is discharged through discharge pipe.If when the moving direction of piston is returned to the right, pumping cylinder left side sucks liquid, and liquid is discharged on pumping cylinder right side, and reciprocal so not having a rest sucks liquid to discharge, and forms the work of pump.
And the liquid entering hole place of manual pump is often all provided with end cap, can effectively prevent that some foreign material from entering pump body, and in using pump, all need first end cap to be backed out, place on one side, then the fixing water pipe at liquid entering hole place, and so, if water pipe does not fix and easily comes off, and due to end cap is placed on one side, often easily forget end cap is taken back, cause certain puzzlement.
Model utility content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of have compress water pipe function and end cap is not easy the manual pump of losing.
For achieving the above object, the utility model provides following technological scheme: a kind of manual pump, comprise the pump housing and handle, the two side that the described pump housing is parallel to each other is provided with oil outlet, the described pump housing is provided with it sidewall that oil outlet sidewall is vertical and is provided with liquid entering hole, described liquid entering hole place is provided with end cap, described handle and the pump housing are hinged, described oil outlet place is provided with annular convex rib, the outer ring surface of described annular convex rib is provided with the first screw thread, described end cap is provided with the second screw thread with the first screw-thread fit, the height of described annular convex rib is greater than the height of end cap, point lid that described end cap is communicated by several size and shapes back to one end of liquid entering hole forms, all side walls hinged with end cap of described point of lid, described point lid and the side walls hinged place of end cap are provided with draught spring, one end of described draught spring is fixedly connected with a point lid, the other end is fixedly connected with the sidewall of end cap.
Preferably, described end cap is greater than the sectional dimension of annular convex rib along its radial direction back to one end of liquid entering hole along the sectional dimension of annular convex rib radial direction.
Preferably, described end cap is made up of 4 slices points of lids back to one end of liquid entering hole.
Preferably, described handle is arranged with anti-slip rubber back to one end of the pump housing.
Compared with prior art, the beneficial effects of the utility model are: when not using the use of the pump housing, end cap is positioned at liquid entering hole place, between each point of lid, form and be sealed and matched, now draught spring in the raw, can prevent the pump body that enters of some reptiles and so on, in the time that needs are intake by liquid entering hole, rotary end cover, make the direction motion of end cap towards the pump housing, along with the motion of end cap, divide lid to contact with annular convex rib, then divide lid to rotate around itself and the side walls hinged place of end cap, until point lid is parallel with the axial direction of annular convex rib, then water pipe is inserted in to annular convex rib place, due to now draught spring generation resiliently deformable, therefore draught spring also can play to water pipe the effect of compression, anti-water stopping tube comes off from annular convex rib, and end cap links together with annular convex rib finally, can effectively prevent the loss of end cap.

Fig. 2 is the utility model manual pump embodiment's explosive view;
Fig. 3 is the structural drawing of end cap.
Reference character: 1, the pump housing; 11, liquid entering hole; 12, oil outlet; 2, handle; 3, anti-slip rubber; 4, end cap; 41, divide lid; 5, draught spring; 6, annular convex rib.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model manual pump embodiment is described further.
A kind of manual pump, comprise the pump housing 1 and handle 2, the two side that the described pump housing 1 is parallel to each other is provided with oil outlet 12, the described pump housing 1 is provided with it sidewall that oil outlet 12 sidewalls are vertical and is provided with liquid entering hole 11, described liquid entering hole 11 places are provided with end cap 4, described handle 2 is hinged with the pump housing 1, described oil outlet 12 places are provided with annular convex rib 6, the outer ring surface of described annular convex rib 6 is provided with the first screw thread, described end cap 4 is provided with the second screw thread with the first screw-thread fit, the height of described annular convex rib 6 is greater than the height of end cap 4, point lid 41 that described end cap 4 is communicated by several size and shapes back to one end of liquid entering hole 11 forms, all side walls hinged with end cap 4 of described point of lid 41, described point lid 41 is provided with draught spring 5 with the side walls hinged place of end cap 4, one end of described draught spring 5 is fixedly connected with a point lid 41, the other end is fixedly connected with the sidewall of end cap 4.
When not using the use of the pump housing 1, end cap 4 is positioned at liquid entering hole 11 places, 41 formation of each point of lid are sealed and matched, now draught spring 5 in the raw, what can prevent some reptiles and so on enters the pump housing 1 inside, in the time that needs are intake by liquid entering hole 11, rotary end cover 4, make the direction motion of end cap 4 towards the pump housing 1, along with the motion of end cap 4, divide lid 41 to contact with annular convex rib 6, then divide lid 41 to rotate around itself and the side walls hinged place of end cap 4, until point lid 41 is parallel with the axial direction of annular convex rib 6, then water pipe is inserted in to annular convex rib 6 places, owing to there is resiliently deformable in draught spring 5 now, therefore draught spring 5 also can play to water pipe the effect of compression, anti-water stopping tube comes off from annular convex rib 6, and end cap 4 links together with annular convex rib 6 finally, can effectively prevent the loss of end cap 4.
End cap 4 is greater than the sectional dimension of annular convex rib 6 along its radial direction back to one end of liquid entering hole 11 along the sectional dimension of annular convex rib 6 radial direction, according to lever principle, makes point lid 41 more easily rotate around its articulating point in the process of rotary end cover 4.
End cap 4 is made up of 4 slices points of lids 41 back to one end of liquid entering hole 11, can play the effect that compresses water pipe, has the installation that facilitates water pipe.
In order to facilitate handle with sleeve 2, handle 2 is arranged with anti-slip rubber 3 back to one end of the pump housing 1.
