Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail.
Filter membrane clip as shown in Figure 1 and Figure 2, including the upper clamp ring 1 and lower clamping 2 being detachably connected, the lower clamping 2 wrap
Annular bottom plate 2-1 and the riffled tube 2-2 for being connected to annular bottom plate outer rim and upwardly extending are included, the upper clamp ring 1 includes annular
Top plate 1-1 and the male-pipe 1-2, the riffled tube 2-2 and external screw thread for being connected to annular roof plate 1-1 inner edges and extending downwardly
Pipe 1-2 cooperates, it is characterised in that the annular bottom plate 2-1 upper surfaces are additionally provided with an annular groove 2-3, the annular groove
Ring spring 2-4 is provided with 2-3, ring spring 2-4 upper ends are provided with a ring washer 2-5 coaxial with annular bottom plate 2-1, the ring
Shape packing ring 2-5 external diameter is not more than riffled tube 2-2 internal diameter and the internal diameter not less than male-pipe 1-2, the upper clamp ring 1 revolve
Ring spring 2-4 is in compressive state when tight, when upper clamp ring 1 and lower clamping 2 are separated, spiral shell in ring washer 2-5 upper surface stretching
Line pipe 2-2 upper end.
Ring washer 2-5 is jacked up by ring spring 2-4 so that riffled tube 2-2 is stretched out in ring washer 2-5 upper surface
Outside, so as to which also the filter membrane 3 on ring washer 2-5 is fed directly to outside riffled tube 2-2, tweezers side can be used in operating personnel
Just filter membrane 3 is removed, filter membrane 3 will not be caused to shake when removing filter membrane 3, therefore, do not interfere with the dust on filter membrane 3
