Abstract

The utility model discloses a liquid pump structure which is mainly composed a pump body, a movable piston, a handle, a center shaft, a liquid outlet pipe, a liquid inlet base and the like. The end portion of the handle is in pivot joint with one end of the center shaft, and the other end of the center shaft penetrates through the top of the pump body and is connected with the movable piston in a chamber of the pump body. The liquid outlet pipe is connected with a liquid outlet connection seat of the pump body, and the bottom of the pump body is provided with the liquid inlet base which is directly connected with a liquid inlet pipeline or a liquid storing barrel. The outer layer of the connection portion of the liquid outlet connection seat is provided with threads, and an inner hole of the liquid outlet connection seat gradually contracts from an open end to the inside of the inner hole. An insertion portion is arranged, on one side of a protruded ring, on the liquid outlet pipe in an extended mode so that the liquid outlet pipe can abut against the inner hole of the liquid outlet connection seat through an end arc of the insertion portion and be closed. Due to the fact that a nut is tightly locked on the liquid outlet connection seat, the liquid outlet pipe can rotate without the assistance of any tool, and an end opening of the pipe is made to face upwards.

Description

Draw the pump structure

Technical field

A kind of pump structure of drawing, particularly a kind of for the innovation pumping configuration drawn water or fluid enters pump body and derives.

Background technique

Press, refer to Fig. 1, prior art is drawn the combination of its pump body 7 of pump and drain pipe 75, the joint 711 and drain pipe 75 combinations of its fluid base 71 of profit, wherein, for preventing that fluid from leaking outside, therefore its seal ring 751 is located between drain pipe 75 and fluid base 71 and mat nut 752 imposes strongly packing and combination.Though use seal ring 751 can reach suitable leakage-proof effect, but when it draws pump for a long time or after repeatedly dismounting is used, its seal ring 751 still can omit gradually passivation because of factors such as environment, temperature and life-spans and cause the oil liquid leakage situation, when occurring, this situation surely will be changed or be upgraded the inconvenience that so increases user cost and use.

The model utility content

Therefore, the purpose of this utility model is to provide a kind of pump structure of drawing, and particularly a kind ofly is easy to draw water or the innovation control structure of fluid.

For reaching above-mentioned purpose, the utility model provides a kind of pump structure of drawing, mainly by pump body, movable piston, handle, central shaft, drain pipe and enter the primary clusterings such as liquid base and combine, one end pivot joint of this handle end and central shaft, the other end of central shaft passes the pump body top and links in the room of pump body with movable piston, this drain pipe is connected with the fluid connecting base of pump body, this pump body bottom is provided with into the liquid base and directly is connected with liquid-in pipe road or liquid storage barrel, the skin of the joint of this fluid connecting base is provided with screw thread, and its endoporus inwardly is gradually-reducing shape by opening end, this drain pipe is to extend insertion part in bulge loop one side, its arc of end by this insertion part must be supported with the endoporus of fluid connecting base only closed, by nut, tightly be locked on the fluid connecting base, drain pipe and fluid connecting base are supported only closed, and drain pipe can not borrowed the rotation of any instrument ground, make tube opening upward.

The beneficial effects of the utility model: by said structure, by nut, tightly be locked on the fluid connecting base, drain pipe and fluid connecting base supported only closed, can effectively prevent that fluid from spilling; And drain pipe can not borrowed the rotation of any instrument ground, makes tube opening avoid managing interior oil residues drop upward and goes out to pollute or waste.

Main symbol description

7 pump bodies; 71 fluid bases; 711 joints; 75 drain pipes; 751 seal rings; 752 nuts;

1 pump body; 11 rooms; 12 fluid connecting bases; 121 joints; 122 screw threads; 123 endoporus; 13 enter the liquid base; 2 movable pistons; 3 handles; 4 central shafts; 5 drain pipes; 51 bulge loops; 52 insertion parts; 521 end arcs; 53 nuts.

Embodiment

Please refer to Fig. 2 to Fig. 6, a mode of execution of the present utility model, main purpose of the present utility model, be to draw the pump structure improvement, that mainly by leader's 3 operational control center axles 4, does upper and lower displacement draws the liquid pump structure, be provided with the movable piston 2 of central shaft 4 in room 11 in its pump body 1, and pump body 1 bottom interlocking enter liquid base 13; That utilizes handle 3 makes the liquid in its pump body 1 room 11 produce pressure difference by pressure-controlled, be really the air in body matter chamber 11 to be squeezed fully, and the adsorptivity of mat liquid level tension force, make the closely sealed effect of movable piston 2 stable generation, and then reach the body interior vacuum state, provide and draw the operation effect that water or fluid enter the main body convenience.And then, the pump structure of drawing of the present utility model, mainly by pump body 1, movable piston 2, handle 3, central shaft 4, drain pipe 5 and enter the formations that primary clustering is organized such as liquid base 13, wherein, one end pivot joint of handle 3 ends and central shaft 4, its user can see through squeeze grip 3 and make to draw the action that pump starts to draw liquid, wherein, the other end of central shaft 4 passes pump body 1 top and links with the room 11 of movable piston 2 in pump body 1, drain pipe 5 is connected with the fluid connecting base 12 of pump body 1, pump body 1 bottom is provided with into liquid base 13, it must directly be connected with liquid-in pipe road or liquid storage barrel, the skin that fluid connecting base 12 more comprises joint 121 its joints 121 is provided with screw thread 122, its endoporus 123 inwardly is gradually-reducing shape by opening end, drain pipe 5 comprises a bulge loop 51 and extends an insertion part 52 is set in drain pipe 5 ends, the end arc 521 that inserts it into section 52 supports only closed with the endoporus that is gradually-reducing shape 123 of fluid connecting base 12, last by a nut 53, be sheathed on outside the outer and screw thread 122 that see through nut 53 and joint 121 of drain pipe 5 is spirally connected again, more utilize bulge loop 51 and its nut 53 to support.

Accordingly, aforementioned drain pipe 5 more can be in the situation that hand-free instrument pine oil nut 53, footpath is directly revolved its drain pipe 5 to move with hand and is made opening up (as shown in Figure 5), so can avoid keeping somewhere the fluid drippage in drain pipe 5, become environmental pollution or waste, and must support the only gradually-reducing shape endoporus 123 of fluid connecting base 12 joints 121 because of the end arc 521 of its insertion part 52.

The above implements the announcement of kenel in order to the utility model to be described, not in order to limit the utility model, therefore the displacement of the change of numerical value or equivalent elements must be subordinate to category of the present utility model such as.
