Abstract

The utility model discloses a hand pressing water well which comprises a well body, a pressing handle, a piston and a check valve assembly which is arranged on the bottom of the well body. The utility model is characterized in that the piston is composed of a positioning hard rubber pad with a water inlet, and a sealing soft rubber pad, and the piston is fixed on the pressing handle. The check valve assembly comprises a sealing soft rubber pad and a branching and positioning device which is arranged under the sealing soft rubber pad, wherein, the sealing soft rubber pad is erected on the water inlet of the bottom of the well. The utility model has the advantages of simple structure, good sealability, high water absorption efficiency, high durability, economy and environmental protection. The assembly of the utility model can be completed by using simple fasteners and positioning devices, the repair and the maintenance are simple and convenient, materials of the piston and the check valve are easy to obtain, the utility model can be prepared by self by using waste tyres, and the expense is low and cheap.

Description

The hand well

Technical field

The utility model relates to a kind of hand well.

Background technology

Pumped well commonly used as shown in Figure 1, mainly by well body 1, pressure handle 2, piston 3 and one way valve 4 are formed, piston 3 is made of two round metal sheet 31 therebetween one sealing mats 32 of bringing the mouth of a river into, need by the four-hole screw fastening, sealing mat is thinner, easy abrasion deformation, cause water-taking efficiency low, the one way valve 4 of water inlet, well body bottom, its valve is to be fixed on the base by screw equally, because one way valve 4 is lighter, be easy to levitating and cause the displacement of whole one way valve 4, and valve also walks easily in this structure, so sealing is relatively poor, easily leak, be difficult to water is drunk up.Simultaneously, because securing member is more, so maintenance maintenance is convenient inadequately, and must buy the supporting sealing mat of size, one way valve etc., and cost is higher.

Summary of the invention

For addressing the above problem, it is simple and convenient that the purpose of this utility model provides a kind of maintenance maintenance, good sealing effect, the hand well that water-taking efficiency is high.

The purpose of this utility model is achieved in that a kind of hand well, the check valve assembly that comprises well body, pressure handle, piston and well body bottom, it is characterized in that: described piston is made up of the location ebonite pad of bringing the water hole into and sealing flexible glue pad, be fixed on the pressure handle, the branching positioner that check valve assembly comprises sealing flexible glue pad and is fixedly arranged on sealing flexible glue pad below, sealing flexible glue poppet is located on the water inlet of shaft bottom.

Also be provided with the contraction rubber cushion that one deck is brought the water hole between the sealing flexible glue pad of described piston and the location ebonite pad, to increase its durability and sealing.

Described check valve assembly is provided with two sealing flexible glue pads, and middle ware is separated with a distortion flexible glue pad.

The branching of described branching positioner makes progress, and rubber cushion is fixed on the trunk of branching positioner by nut and sheet metal.

The utility model is simple in structure, can finish assembling by simple securing member and positioner, sealing is good, the water-taking efficiency height, and also durable, even maintenance maintenance is also very simple and convenient, the material of piston and one way valve is easy to get, and can utilize discarded tire to prepare voluntarily, and expense is cheap, not only economical, and environmental protection.

Description of drawings

Fig. 1 is the structural representation of old-fashioned hand well;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the enlarged drawing of the utility model check valve assembly.

The specific embodiment

As shown in Figure 2, the utility model comprises the check valve assembly 6 of well body 1, pressure handle 2, piston 5 and bottom.Piston 5 from bottom to top is made up of location ebonite pad 54, contraction rubber cushion 53 and sealing flexible glue pad 52, diameter increases successively, shrink rubber cushion 53 and locate ebonite pad 54 and be provided with the inlet opening, above sealing flexible glue pad 52, be provided with flexible glue Jie money 51, ebonite pad 54 belows, location are provided with nut 55, with each elastic mounting on pressure handle 2.When piston 5 pressed down, water entered piston 5 upper spaces by the inlet opening of shrinking rubber cushion 53 and location ebonite pad 54, and when carrying on the piston 5, sealing flexible glue pad 52 is sealed into the water hole, hydraulic pressure can be gone out well body 1.Check valve assembly 6 comprises sealing flexible glue pad 63, distortion flexible glue pad 64 and branching positioner 65 (as shown in Figure 3).Distortion flexible glue pad is equipped with sealing flexible glue pad 63 in both sides about in the of 64, and the trunk of branching positioner 65 runs through each rubber cushion, and with elastic mounting, branching is generally three wooden forks or four wooden forks by nut 61, sheet metal 62, and the wooden fork mouth upwards pushes up to the rubber cushion bottom.In the intake tunnel at the bottom of branching positioner 65 fill-in wells of check valve assembly 6, rubber cushion then is set up on the water inlet of shaft bottom, can whole taking-up keep in repair, trunk length should be designed to that its trunk does not break away from water inlet yet when piston 5 arrives maximum heights, so that guide-localization.Because its weight is heavier, and branching positioner guiding is arranged, so contraposition is accurate, and can wholely moves up and down, rubber cushion is not easy to wear, so soaking effect is good.Flexible glue pad 52,63,64 etc. all can utilize discarded tire to cut out voluntarily and form, and expense is cheap.

During use, drive pistons 5 by pressure handle 2 and move up and down, simultaneously whole check valve assembly 6 also and up and down along with pressure and suction, open or sealed well at the bottom of water inlet, thereby reach the effect of suction.
