Abstract
The utility model discloses a kind of fast inserting structure of diaphragm pump, the socket comprising quick inserting joint and coordinate with quick inserting joint, on described quick inserting joint, sheathed stopping retaining ring, sheathed lining on retaining ring stopping, be arranged at intervals with claw in lining circumference, between socket inwall and quick inserting joint, be provided with O type circle, socket is provided with step, by arranging pressing plate at socket extenal fixation, make lining limited in socket, now claw is compacted between pressing plate and mesa sidewall.The utility model is by arranging the lining with claw outward at quick inserting joint, first lining is inserted in the socket of diaphragm pump during installation, in this socket, step is set, then outside socket, a pressing plate is fixedly installed by fastening piece, lining and quick inserting joint are fixed in socket, now claw is compacted between pressing plate and the wall of step, even if therefore when lining is subject to larger pump housing fluid intraventricular pressure, claw turnover also can not occur thus cause lining in the problem of socket axial displacement.
Description
Technical field
The utility model relates to pump field, more specifically, relates to a kind of for connecting diaphragm pump water intake, fast inserting structure between water outlet and adapter assembly.
Background technique
Diaphragm pump is a kind of form comparatively special in displacement pump.It relies on agitating back and forth of diaphragm and changes swept volume of a single chamber to suck and discharge liquid.Diaphragm pump comprises water intake and water outlet, water intake with water outlet is all connected quick inserting joint, for connecting water pipe.Traditional diaphragm pump all adopts the Placement of thread type in quick inserting joint and inlet/outlet, and above-mentioned Placement is very inconvenient when assembling.
Based on above-mentioned defect, see Fig. 1 and Fig. 2, the fast inserting structure of a kind of diaphragm pump known at present includes lining 100 and stops and retaining ring 101, quick inserting joint 102 is located in described lining 100 by stopping card release retaining ring 101, a circle claw 103 is arranged at intervals with in lining 100 circumference, described claw 103 is inserted 100 opposite directions entering the direction of socket to described lining and is tilted, the O type circle 104 being also included in quick inserting joint 102 outer side wall and arranging between described socket madial wall, said structure is when quick inserting joint is installed, by the integral piece of lining and quick inserting joint is inserted socket, due to the setting of claw, when lining is subject to the power along socket outward direction, there is between claw and socket inwall very large damping, prevent it from deviating from.
But said structure is existing problems still: when water outlet shutoff, pump housing fluid chamber inside will produce interior pressure, and seal ring and quick inserting joint are interference fit, so make seal ring also outwards can produce displacement, can lean to stop at seal ring and quick inserting joint in the process of outwards movement and retaining ring, to making these three parts all to outer displacement, now lining also stops outwards movement in the process and move outside retaining ring, and lining can make its claw can't hold out against the inwall in hole in the process of outer displacement, now claw will move outward.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of chamber of septum structure.
The utility model is achieved through the following technical solutions: a kind of fast inserting structure of diaphragm pump, the socket coordinated with described quick inserting joint comprising quick inserting joint and arrange in fluid chamber, described quick inserting joint is arranged with to stop and retaining ring, described stop on retaining ring be arranged with lining, claw is arranged at intervals with in described lining circumference, O type circle is provided with between described socket inwall and described quick inserting joint, described socket is provided with step, by arranging pressing plate at described socket extenal fixation, make described lining limited in described socket, now described claw is compacted between described pressing plate and mesa sidewall.
In technique scheme, the through-hole diameter on described pressing plate is less than the diameter of described lining and two-layer jaw thicknesses sum.Such lining is being deviate from process, unless pressing plate is risen bad completely, not so cannot deviate from, further ensure reliability.
In technique scheme, described claw inserts opposite direction from the direction of socket to described lining tilts.
In technique scheme, described one end retaining ring of stopping is provided with axially some axially extended breach.
The utility model has following beneficial effect: the utility model is by arranging the lining with claw outward at quick inserting joint, first lining is inserted in the socket of diaphragm pump during installation, in this socket, step is set, then outside socket, a pressing plate is fixedly installed by fastening piece, lining and quick inserting joint are fixed in socket, now claw is compacted between pressing plate and the wall of step, even if therefore when lining is subject to larger pump housing fluid intraventricular pressure, also can not there is claw turnover thus cause lining in the problem of socket axial displacement.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: see Fig. 3 to Fig. 5, a kind of fast inserting structure of diaphragm pump, in the socket 3(the present embodiment coordinated with described quick inserting joint comprising quick inserting joint 1 and arrange in fluid chamber 2, socket 3 refers to water intake or the water outlet of diaphragm pump), described quick inserting joint 1 is arranged with and stops retaining ring 6, described stop on retaining ring 6 be arranged with lining 4, be arranged at intervals with claw 40 in described lining 4 circumference, the opposite direction that described claw 40 inserts the direction of socket 3 to described lining 4 tilts.The sealing of O type circle 7 for rapid pipe joint and socket inwall is provided with between described socket inwall and described quick inserting joint 1.Described socket 3 is provided with step 30, and by arranging pressing plate 5 at described socket 3 extenal fixation, make described lining 4 limited in described socket 3, now described claw 40 is compacted between described pressing plate 5 and step 30 sidewall.Through-hole diameter on pressing plate 5 is less than diameter and the two-layer claw 40 thickness sum of lining 4.Such lining is being deviate from process, unless pressing plate is risen bad completely, not so cannot deviate from, further ensure reliability.
Described one end retaining ring 6 of stopping is provided with axially some axially extended breach 60, due to the setting of above-mentioned breach, when needs dismounting lining, can by applying along its circumference pressure inwards stopping the other end retaining ring 6, make to stop and one end that retaining ring 6 has breach 60 place and tightened up, now stop retaining ring 6 and can being pulled out from lining.
Described in the fast inserting structure of the utility model, lining is fixedly connected with described quick inserting joint, by arranging the lining with claw outward at quick inserting joint, first lining is inserted in the socket of diaphragm pump during installation, in this socket, step is set, then outside socket, a pressing plate is fixedly installed by fastening piece, lining and quick inserting joint are fixed in socket, now claw is compacted between pressing plate and the wall of step, even if therefore when lining is subject to larger pump housing fluid intraventricular pressure, also can not there is claw turnover thus cause lining in the problem of socket axial displacement.
