Description

Manual diaphragm pumps

Technical field

The utility model is related to a kind of diaphragm pump, more specifically, it relates to which a kind of manual diaphragm pumps.

Background technology

Manual diaphragm pump is used for the water lift operation of low lift, small flow, by the pump housing, water inlet pipe and water outlet pipe, Inlet and outlet water valve, membrane With the compositions such as push-pull rod.The pump housing includes the left pump housing and the right pump housing, and two membranes are attached separately on the outside of two pump chambers separated.Work When the handwheel that is connected by people with manual operating with membrane, promote the reciprocating motion that membrane is pressed into and opens using push-pull rod, make a left side Chamber and the indoor volume of right chamber alternately expand and reduce.During work, easily there is the promotion to membrane in push-pull rod Position not accurately situation, causes the work quality of integral pump to decline so that pump efficiently can not carry out inspiration to media fluid With the work of discharge, the use quality of equipment is affected.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide accuracy higher during a kind of work, A kind of higher manual diaphragm pump of work quality.

To achieve the above object, the utility model provides following technical solution：

A kind of manual diaphragm pump, including the pump housing, the pump housing includes intermediate and the left pump housing positioned at intermediate both ends With the right pump housing, the interior lower end company for being equipped with left chamber, right chamber, the left chamber and right chamber being equipped in the right pump housing of the left pump housing Water pipe is tapped into, upper end is connected with outlet pipe, and push-pull rod is equipped in the intermediate, and the both ends of push-pull rod, which contradict, is connected with push Portion, the push part extend respectively to left chamber, in right chamber, the left chamber and the company of intermediate, right chamber and intermediate The place of connecing is equipped with membrane, and the push part is contradicted with membrane and connected, and the push part includes movable end and compresses end, described to compress End is made of rubber material and is set in sucker shape, and with membrane in conflict state, one end of the opposite connection of the movable end is equipped with Rubber bulge loop, the end of the push-pull rod are equipped with the groove being embedded for movable end.

The utility model is further arranged to：The membrane includes interior diaphragm and outer membrane, the interior diaphragm and outer membrane Outer edge fixed by snap ring, cushion is equipped between the interior diaphragm and outer membrane, the cushion distinguished by glue It is bonding with interior diaphragm, outer membrane.

By using above-mentioned technical proposal, contradicted in push rod and be connected with push part, using push part come to membrane into Row pushes the work forward, and can promote the accuracy of work.Simultaneously by the structure for compressing end and being arranged to sucker shape in push part, pushing away During dynamic membrane, the fastness connected between the two can be enhanced, can efficiently be promoted membrane so that the work quality of integral pump is more It is high.

Specific embodiment

Embodiment is pumped referring to figs. 1 to Fig. 3 to a kind of manual diaphragm of the utility model 5 to be described further.

A kind of manual diaphragm 5 pumps, and including the pump housing 1, the pump housing 1 includes intermediate 2 and positioned at 2 both ends of intermediate The left pump housing 3 and the right pump housing 4, the left pump housing 3 is interior to be equipped with left chamber 30, and right chamber 40, the left chamber 30 are equipped in the right pump housing 4 Water inlet pipe 6 is connected with the lower end of right chamber 40, upper end is connected with outlet pipe 7, push-pull rod 20, push-and-pull are equipped in the intermediate 2 The both ends of bar 20, which contradict, is connected with push part 21, and the push part 21 extends respectively to left chamber 30, in right chamber 40, the left side Chamber 30 is equipped with membrane 5 with intermediate 2, right chamber 40 and the junction of intermediate 2, and the push part 21 is contradicted with membrane 5 Connection, the push part 21 include movable end 210 and compress end 211, and the end 211 that compresses is made of rubber material in sucker shape It sets, with membrane 5 in conflict state, one end of the opposite connection of the movable end 210 is equipped with rubber bulge loop 212, the push-and-pull The end of bar 20 is equipped with the groove 200 being embedded for movable end 210.

At work, push-pull rod 20 is first towards left chamber's 30 direction movement, the end of push-pull rod 20 with close to left chamber 30 The push part 21 at end is inconsistent, and movable end 210 is arranged in the groove 200 of push-pull rod 20 in push part 21, on movable end 210 Rubber bulge loop 212 plays the role of enhancing movable end 210 and 200 inner wall frictional force of groove so that push-pull rod 20 is to push part 21 Pushing position is more accurate.Simultaneously so that in push part 21 to compress end 211 inconsistent with membrane 5, continue to move, by membrane 5 The state inconsistent with the inner wall of left chamber 30 is pushed to, the structure that end 211 is sucker shape is compressed, membrane 5 can firmly be held, Ensure that the position that membrane 5 pushes is accurate, the volume in left chamber 30 is become smaller, completes the discharge work of media fluid.Then push away Pull rod 20 is moved towards 40 direction of right chamber, and compressing end and 211 can holding membrane 5 for sucker shape drives membrane 5 to be restored to originally State, when push-pull rod 20 is inconsistent with push part 21 close to right chamber 40, the membrane 5 in the left chamber 30 is with compressing The conflict at end 211 will disconnect, and movable end 210 can also depart from out of push rod upper groove 200, and push-pull rod 20 continues orientation movements Right chamber 40.It is moved back and forth with push-pull rod 20 towards left chamber 30,40 direction of right chamber, reaches and inhale media fluid Into the work with discharge.After such structure is improved so as to the push work accuracy higher of membrane 5, pump can be greatly promoted Work quality.

The membrane 5 includes interior diaphragm 50 and outer membrane 51, and the outer edge of the interior diaphragm 50 and outer membrane 51 passes through card Ring 52 is fixed, between the interior diaphragm 50 and outer membrane 51 be equipped with cushion 53, the cushion 53 by glue respectively with it is interior Diaphragm 50, outer membrane 51 are bonding.Membrane 5 is arranged to interior diaphragm 50 and outer membrane 51, the intensity of membrane 5 can be increased, together When inside cushion 53, can play the role of compensator or trimmer pressure when membrane 5 deforms, the tough of membrane 5 can be promoted Property, the working life of extension membrane 5.

The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, several improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
