It is provided with screwed hole, the pump head seat and offers and escapement seat quantity and position pair on the multiple escapements set, the escapement
The through hole answered, the escapement is located in the through hole, is provided with to be provided with locating dowel, piston thrust block on the diaphragm and matches somebody with somebody
The positioning hole of the locating dowel is closed, the piston thrust block is arranged on the diaphragm and the locating dowel is located at the positioning hole
Interior, the piston thrust block and the escapement are fixed by fastener, and the escapement is included in the plane domain of its upper surface setting,
The locating dowel is located on the plane domain of escapement end face in the projection of vertical direction.
In above-mentioned technical proposal, delineation position concave ring groove is provided with the periphery of the screwed hole, under the diaphragm
End is provided with a circle positioning convex ring, and the positioning convex ring is set in the positioning concave ring groove.
In above-mentioned technical proposal, set jagged between escapement seat is located at each escapement.
In above-mentioned technical proposal, a circle bulge loop is provided with the outer peripheral edge of the diaphragm, from the center of the diaphragm
3 convex tendons being connected with above-mentioned bulge loop are extended in position, and the diaphragm is separated into 3 pistons by the convex tendon and the bulge loop
Installation region, is provided with escapement described in 3 groups accordingly.
The utility model has the advantages that：The utility model by locating dowel by being arranged in escapement upper surface
The plane domain of setting so that the amount of tension of the basic wall thickness part of diaphragm and the junction of locating dowel is lowered significantly, finally
Reduce the problem of diaphragm is broken.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is exploded perspective view of the present utility model.
Fig. 3 is schematic cross-sectional view of the present utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 to Fig. 3,
A kind of diaphragm structure, including pump head seat 1, be arranged at the diaphragm 2 of 1 one side end faces of pump head seat and be arranged at the pump head seat
A circle bulge loop 23 is provided with the escapement seat 3 of opposite side, the outer peripheral edge of the diaphragm 2, from the center of the diaphragm 2
Extend 3 convex tendons 22 being connected with above-mentioned bulge loop 23, the diaphragm 2 is separated into 3 by the convex tendon 22 and the bulge loop 23
Individual piston installation region.
Escapement seat 3 is included in 3 groups of escapements 30 of its end face setting, escapement seat be located at 3 each escapement 30 it
