[0021] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figures 1 to 3As shown, the proton membrane flattening clamp consists of an outer clamping part 1 , an inner clamping part 2 assembled on the inner side of the outer clamping part 1 , and an adjusting structure 4 arranged on the outer clamping part 1 .
[0023] There is a proton membrane fixing space 3 between the outer clamping part 1 and the inner clamping part 2, which is used for the clamp to fix and clamp the proton membrane so that the membrane itself will not be offset or wrinkled during the performance test. Figure 3 The shaded part in the figure is a schematic diagram of the proton membrane, and the dotted circle part is a schematic diagram of the inner clamping space covered by the proton membrane. The edge of the inner clamping part 2 extends into the proton membrane fixing space 3 and extends to the bottom of the clamp. At the same time, with the help of the support effect of the outer ring edge of the inner clamping part 2 on the proton membrane, the proton membrane can be flattened in the clamp.
[0024] In this embodiment, an adjustment port 101 is provided on the outer clamping part 1, and fastening gaskets 5 are respectively installed on both sides of the outer opening of the adjustment port 101, and the adjustment structure 4 is installed and connected with the adjustment port 101 through the fastening gaskets 5. The outer clamping part 1 and the adjustment structure 4 are fixedly connected through the fastening gaskets 5, giving the operator a certain manual operation space, and the adjustment of the clamp is more convenient and smooth.
[0025] In this embodiment, the fastening gasket 5 includes a connecting portion connected to the outer clamping portion 1 through a blind rivet 501 and an adjusting portion matched with the adjusting structure 4. The connecting portion and the adjusting portion are integrally formed, the connecting portion is arranged to fit the outer ring contour of the outer clamping portion 1, an adjusting light hole is opened on the adjusting portion, and the adjusting structure 4 passes through the adjusting light hole and is matched with the adjusting portion.
[0026] As for how to adjust the size of the adjustment port 101, the combination of bolts and nuts in the adjustment structure 4 is adopted. Specifically, the adjustment structure 4 includes a limit bolt 401 and a pad nut 402; the limit bolt 401 includes a screw rod and a bolt head, the screw rod and the bolt head are connected as one, and the surface of the bolt head is provided with anti-skid patterns, thereby forming an anti-skid twisting part, the cross-sectional diameter of the anti-skid twisting part is larger than the diameter of the adjustment light hole, so the anti-skid twisting part can be limited to the outside of the fastening gasket 5 to play a role in limiting and fixing. At the same time, a padding part 403 is provided at one end of the pad nut, and the padding part 403 is provided so that the staff can conveniently grasp and twist the nut when making adjustments. The bolt head is limited to the outside of the fastening gasket 5, and the heightening nut is limited to the outside of the other fastening gasket 5, thereby clamping the two fastening gaskets 5, and then adjusting the diameter of the outer clamping part 1 by adjusting the spacing between the adjustment openings 101 clamped by the two fastening gaskets 5. Since the outer clamping part 1 is made of bamboo material, it has a certain toughness, so its diameter can be adjusted, so that the space size of the proton membrane fixing space 3 after adjustment can adapt to the membrane thickness of the proton membrane.
[0027] In this embodiment, the outer clamping part 1 and the inner clamping part 2 are both made of bamboo material. The manufactured proton membrane flattening clamp is light in weight and has a certain plasticity. The corresponding production cost is low, the structural setting is simple, the operability is strong, and no external energy consumption is required to achieve clamping of the clamp during use.
