Abstract
The utility model provides a kind of integrated septum of diaphragm pump, comprises diaphragm main body and barrier film inserts, and described diaphragm main body side is sealing surface, and opposite side extends the connecting part be connected with described barrier film inserts; One end that described barrier film inserts engages with diaphragm main body is provided with connecting chuck.The utility model avoids existing barrier film and relies on screw to connect the seepy question caused.
Description
Technical field
The utility model relates to a kind of integrated septum of diaphragm pump.
Background technique
In traditional diaphragm pump, barrier film and Placement thereof piston, barrier film are connected with driving head by screw; Barrier film relies on screw to make piston and driving head compress barrier film and seals, and like this, there is screw and installs the seepy question caused not in place.
Model utility content
The utility model provides a kind of integrated septum of diaphragm pump, relies on screw to connect, there is screw and install the seepy question caused not in place to solve existing barrier film.
For this reason, the utility model proposes a kind of integrated septum of diaphragm pump, comprise diaphragm main body and barrier film inserts, described diaphragm main body side is sealing surface, and opposite side extends the connecting part be connected with described barrier film inserts; One end that described barrier film inserts engages with diaphragm main body is provided with connecting chuck.
Further, the other end outer wall of described barrier film inserts is provided with fastening.
Further, described fastening is outer gibbosity buckle or boss.
Further, be joint between the chuck of described barrier film inserts and fastening, the bore of described chuck is greater than the bore of described joint, and the coated described chuck in the connecting part of described diaphragm main body.
Further, described joint inside is provided with cavity, and described chuck is provided with the through hole connecting described cavity, and described via area is less than the cross-section area of described cavity.
Further, be provided with opening slot in the middle part of described joint, described opening slot extends to described chuck.
Further, described diaphragm main body and described barrier film inserts are integral type structure.
The utility model is by improving the structure of barrier film, barrier film is made to have the chuck be fixedly connected with described diaphragm main body, and clamping can be realized with driving head by chuck to be connected, thus avoid existing barrier film and rely on screw to connect, there is screw and the seepy question caused not in place is installed.
And then the utility model is by being shaped diaphragm main body and described barrier film inserts integrated injection molding, and (1) does not need to use screw and piston to be sealed by barrier film, and sealability is improved; (2) and then, the other end of barrier film inserts is fastening, utilizes the buckle of barrier film inserts, barrier film and barrier film inserts is integrally directly compressed into driving head, does not need screw to be connected with driving head by barrier film, easier for installation.

Embodiment
In order to there be understanding clearly to technical characteristics of the present utility model, object and effect, now contrast accompanying drawing and the utility model is described.
As shown in Figure 1, the integrated septum of the diaphragm pump of the utility model embodiment, comprises diaphragm main body 1 and barrier film inserts 3, and the upside 11 of described diaphragm main body 1 is sealing surface, be such as overall sealing surface, the connecting part 130 be connected with described barrier film inserts is extended in the downside 13 of diaphragm main body; One end that barrier film inserts engages with diaphragm main body is provided with connecting chuck 31, and such as, the upper end of described barrier film inserts is the chuck 31 be connected with the connecting part 130 of described diaphragm main body.
Further, as shown in Figure 2 and Figure 4, the outer wall of the lower end of described barrier film inserts 3 is provided with fastening 35, fastening 35 is such as convex buckle or boss, clamping driving head, links together diaphragm main body, barrier film inserts and driving head, can realize clamping be fast connected with driving head.By the chuck be fixedly connected with described diaphragm main body, clamping can be realized with driving head and be connected, thus avoid existing barrier film and rely on screw to connect, there is screw and the seepy question caused not in place is installed.
Further, as shown in Figure 2 and Figure 4, be joint 33 between the chuck 31 of described barrier film inserts and fastening 35, described chuck 31 is such as circular or is with circle jaggy or sub-circular, the bore of chuck 31 is greater than the bore of described joint 33, and the coated described chuck 31 in the connecting part 130 of described diaphragm main body 1, can firmly be arranged in diaphragm main body 1 to make barrier film inserts.Chuck 31 is such as with jagged, so that the material of diaphragm main body flows into, prevents barrier film and barrier film inserts relative sliding, diaphragm main body and barrier film inserts are better combined.
Further, as shown in Figure 4, described joint 33 inside is provided with cavity 330, as shown in Figure 3, described chuck 31 is provided with the through hole 310 connecting described cavity, and described through hole 310 area is less than the cross-section area of described cavity 330, so that during integral molded plastic, the material of diaphragm main body flows into, and raising diaphragm main body and grabbing of barrier film inserts are made a concerted effort.
Further, as shown in Figure 4, be provided with opening slot 37 in the middle part of described joint 33, described opening slot 37 extends to described chuck 31, and opening slot 37 such as runs through the side direction in the middle part of described joint 33, and opening slot 37 extends to the end face of chuck 31 vertically.The effect of opening slot 37 is: have certain deformation space when buckle sticks into driving head.
Further, described diaphragm main body and described barrier film inserts are integral type structure, such as, be integrated injection molded.During injection moulding barrier film, barrier film inserts is placed in diaphragm mold in advance as inserts, then carries out injection moulding diaphragm main body, and result is that diaphragm main body becomes as a whole with barrier film inserts; Then as shown in Figure 5, in the middle of diaphragm main body 1 and barrier film inserts 3 entirety press-in driving head 5, be in clamping connection by the buckle structure of barrier film inserts and driving head, such three becomes as a whole.Such as, fastening 35 snaps onto in hole clipping or draw-in groove 51.
The advantage that diaphragm main body and described barrier film inserts integrated injection molding are shaped is: (1) barrier film is an entirety, does not need to use screw and piston to be sealed by barrier film, and sealability is improved; (2) easier for installation, utilize the buckle of barrier film inserts, diaphragm main body and barrier film inserts are integrally directly compressed into driving head, does not need screw to be connected with driving head by barrier film.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.For each constituent element of the present utility model can mutually combine under the condition of not conflicting; any those skilled in the art; equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
