Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail.
The filter membrane clip of foldable filter membrane as shown in Figure 1 to 4, including the upper clamp ring 1 being detachably interconnected is with
Clamp ring 2, it is characterised in that the lower clamping 2 includes annular bottom plate 2-1 and the male-pipe 2-2 for being coaxially disposed and upwardly extending,
The upper clamp ring 1 includes the annular roof plate 1-1 and riffled tube 1-2 that is coaxially disposed and extends downwardly, coaxial in riffled tube 1-2
Press mold pipe 1-3 is provided with, press mold pipe 1-3 upper ends are fixedly connected on annular roof plate 1-1, the male-pipe 2-2 and internal thread
Pipe 1-2 screw threads coordinate, and the internal diameter of the male-pipe 2-2 is more than annular bottom plate 2-1 internal diameter and more than the external diameter of filter membrane 3, pressure
Internal diameter of the membrane tube 1-3 external diameter no more than male-pipe 2-2 and the internal diameter not less than annular bottom plate 2-1, the annular bottom plate 2-1
Internal diameter be not more than the external diameter of filter membrane 3, be symmetrically arranged with two semicircles on the annular bottom plate 2-1 upper surfaces in male-pipe 2-2
Ring washer 4, two packing rings 4 are oppositely arranged to form a domain coaxial with male-pipe 2-2, and any packing ring 4 is by being arranged on
The bearing pin 5 of two free end is rotatably connected on male-pipe 2-2 inwall, and torsion spring 6, torsion spring 6 are provided with the bearing pin 5
One end and the lower surface of packing ring 4 offset, the upper surface of the other end and annular bottom plate 2-1 offsets, and the torsion spring 6 drives two packing rings
4 opposite upsets.
Mutually being closed up in the presence of torsion spring 6 by two semi-circular packing rings 4 so that filter membrane 3 is once folded automatically,
Then when taking out filter membrane 3 with tweezers, tweezers are to press from both sides the outside of filter membrane 3 after folding, will not cause shadow to the dust of collection
