Embodiment 1
[0035] Such as Figure 1-Figure 5 As shown, the present invention avoids the method that water purification membrane is damaged, comprises the steps:
[0036] Step A: Loosen the nut 3 until the nut 3 retreats from the screw rod 2;
[0037] Step B: move the stop plate 6 away from the carrying box 1 until the screw 2 withdraws from the through hole 5;
[0038] Step C: Place each water purification membrane assembly in the carrying box 1 in turn, so that the two ends of the water purification membrane assembly are respectively located in a pair of opposite guide grooves 4, and the bottom of the water purification membrane assembly is in contact with the carrying box 1 The bottom of the cavity wall is in contact, and the through hole on the water purification membrane assembly is parallel to the axis of the through hole 5 on the carrying box 1;
[0039] Step D: Pass the end of the screw 2 away from the retaining plate 6 through the through hole 5 on one side of the carrying box ...
Embodiment 2
[0046] Preferably, the distance between the bottom of the guide groove 4 on the inner wall of one side and the bottom of the corresponding guide groove 4 on the other side of the groove wall is consistent with the width of the water purification membrane assembly, and the through hole on the carrying box 1 5 The distance from the bottom of the inner cavity wall of the carrying box 1 is consistent with the size of the through hole on the water purification membrane assembly from the bottom of itself.
Embodiment 3
[0048] An annular groove is arranged on the side of the baffle plate 6 close to the carrier box 1, the axis of the annular groove coincides with the axis of the baffle plate 6, and a sealing ring 8 is embedded in the annular groove, when the baffle plate 6 and the nut 3 are in contact with the bearing box 1, when the nut 3 is screwed relative to the screw rod 2, the sealing ring 8 can be compressed and deformed.
[0049] The compression deformation of the sealing ring 8 increases the axial pressure of the thread between the nut 3 and the screw rod 2 to prevent the nut 3 from being loosened and improves the stability of the present invention.
