Fig. 1 is the utility model example structure decomposing schematic representation;

Fig. 2 is that A-A behind Fig. 1 equipped is to cross-sectional schematic.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1 to embodiment shown in Figure 2, a kind of diaphragm pump rapid pipe joint, comprise the housing 2 that is provided with intake tunnel 10 and exhalant canal 9, exhalant canal 9 is communicated with the first rapid pipe joint assembly, intake tunnel 10 is communicated with the second rapid pipe joint assembly, exhalant canal 9 epicoele walls are shaped at least one first draw-in groove 61, intake tunnel 10 epicoele walls are shaped at least one second draw-in groove 62, card has to block between first clamp, 11, the second draw-in grooves 62 and the second rapid pipe joint assembly between first draw-in groove 61 and the first rapid pipe joint assembly second clamp 12.

The first rapid pipe joint assembly comprises the first equipped Sealing 31 and first clip 51, first clamp 11 is provided with the first through hole 11a coaxial with intake tunnel 10, the first through hole 11a is equipped with first clip 51, and first clip 51, first water pipe 81 of pegging graft and being nested through first Sealing, 31 interference fit; The second rapid pipe joint assembly comprises the second equipped Sealing 32 and second clip 52; Second clamp 12 is provided with the second through hole 12a coaxial with exhalant canal 9, and the second through hole 12a is equipped with second clip 52, and second clip 52, second water pipe 82 of pegging graft and being nested through second Sealing, 32 interference fit.First clamp 11 is assembling after the first through hole 11a fixes first clip 51 on diaphragm pump housing 2, second clamp 12 after the second through hole 12a fixes second clip 52 on diaphragm pump housing 2, prevents that the first rapid pipe joint assembly and the second rapid pipe joint assembly from coming off in assembling.The utility model can separate making with the first rapid pipe joint assembly and the second rapid pipe joint assembly by diaphragm pump housing 2, is fixed together by first clamp 11, second clamp 12, and is defective if any individual component in test, so that in time change dismounting.Second water pipe 82 that first water pipe, 81, the second clips 52 that 51 grafting of first clip are nested through first Sealing, 31 interference fit are pegged graft and are nested through second Sealing, 32 interference fit.First Sealing 31, second Sealing 32 also had certain magnitude of interference and form radial seal with cooperating of first water pipe 81, second water pipe 82.
