[0002] The full name of nuclear pore membrane is nuclear track etched microporous membrane, also known as nuclear microporous membrane, heavy ion microporous membrane, etc. It uses high-energy heavy ions accelerated by heavy ion accelerator to bombard the film (some methods also use fragments of nuclear reactor fission, which can also be used as irradiation sources after collimation) to form nearly continuous atomic defects, namely latent tracks, in the polymer film. Then, a specific chemical solution that is sensitive to the latent track area but not very sensitive to the bulk material is used to etch the film, expanding the nanoscale track damage area to through holes of tens of nanometers to tens of microns. Such a membrane is a nuclear pore membrane.

[0003] During the transportation of fruits and vegetables, a hole for the nuclear pore membrane assembly is often opened on the outside of the fruit and vegetable packaging box, and the nuclear pore membrane assembly is installed in the hole, so that the nuclear pore membrane assembly can be used to adjust the oxygen and carbon dioxide concentrations in the storage environment to achieve spontaneous gas conditioning; in addition, the nuclear pore membrane assembly can also be used to adjust the temperature and humidity environment around the preserved products, and the nuclear pore membrane can block dust from the outside of the storage environment, thereby maintaining the quality of fruits and vegetables, reducing losses, and extending the storage period and shelf life.

[0004] During use of the existing nuclear pore membrane assembly, the nuclear pore membrane is fixed by the pre-tightening force of the clip. This method requires a large force to install and remove the nuclear pore membrane, and the operation is relatively laborious.

[0005] Based on this, a nuclear pore membrane assembly is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1

[0030] In one embodiment, Figure 1-Figure 7As shown, a nuclear pore membrane assembly includes a fixed plate 1, a fixed ring 2, and a mounting clamp 5. The side wall of the fixed plate 1 is fixedly connected with a first threaded barrel 7, the side wall of the fixed ring 2 is fixedly connected with a second threaded barrel 8, the first threaded barrel 7 and the second threaded barrel 8 are threadedly connected, and also includes a mounting structure and a disassembly structure. The side wall of the fixed ring 2 is provided with a hole, and the side wall of the fixed ring 2 near the second threaded barrel 8 is provided with four mounting block grooves, and a mounting clamp 5 is provided between the fixed plate 1 and the fixed ring 2. The side wall of the mounting clamp 5 is fixedly connected with four mounting blocks 6, and the four mounting blocks 6 are respectively slidably connected with the inner side walls of the four mounting block grooves, and a nuclear pore membrane is placed between the mounting clamp 5 and the fixed ring 2. The mounting structure is arranged in the mounting block groove for facilitating the rapid installation of the nuclear pore membrane, and the disassembly structure is arranged on the side wall of the fixed ring 2 for rapid disassembly and replacement of the nuclear pore membrane. When the entire nuclear pore membrane assembly needs to be installed on the fruit and vegetable safety box, it is only necessary to place the fixed plate 1 and the fixed ring 2 on both sides of the fresh-keeping box hole, and the installation can be completed by threading the first threaded barrel 7 and the second threaded barrel 8, and the operation is quick and convenient.

[0031] In one embodiment, Figure 5 and 7 As shown, the mounting structure includes a clamping block 10, and the inner side walls of the four mounting block grooves are all provided with clamping block grooves 13, and a damping spring is fixedly connected between the clamping block 10 and the inner side wall of the clamping block groove 13, and the side walls of the four mounting blocks 6 are all provided with grooves corresponding to the shape of the clamping block 10, and the clamping block 10 is engaged with the groove of the mounting block 6. When the nuclear pore membrane needs to be installed between the fixed plate 1 and the fixed ring 2, the nuclear pore membrane is first placed in the fixed ring 2, and then the four mounting blocks 6 of the mounting clamp 5 are pressed into the mounting block grooves. At this time, the installation can be completed by the clamping block 10 and the damping spring cooperating with the groove of the mounting block 6, and the installation process is quick, convenient, and labor-saving.

[0032] In one embodiment, Figure 7 As shown, the side wall of the clamping block 10 is provided with a chamfer. Since the side wall of the clamping block 10 is provided with a chamfer, the clamping block 10 and the mounting block 6 are clamped more smoothly, and the wear of the clamping block 10 is also reduced.

[0033] In one embodiment, Figure 5 As shown, the side wall of the block 10 is provided with a protrusion, and the protrusion of the block 10 is slidably connected with the inner wall of the block slot 13. The block 10 is limited to prevent the block 10 from sliding out of the block slot 13, which is inconvenient to clamp.

[0034] In one embodiment, Figure 6 and Figure 7As shown, the disassembly structure includes a rotating ring 3 and a pull rope 11, a pull rope cavity 9 is provided on the side wall of the block groove 13, a rotating ring groove is provided on the side wall of the fixed ring 2 away from the second threaded tube 8, the inner side wall of the rotating ring groove is rotatably connected to the rotating ring 3 through a bearing, and the side wall of the block 10 is fixedly connected to the pull rope 11, and the end of the pull rope 11 away from the block 10 is fixedly connected to the side wall of the rotating ring 3 through the pull rope cavity 9. When the nuclear pore membrane needs to be disassembled and replaced, two fingers touch the fixed handle 4, and the rotating ring 3 is rotated in any direction by a certain angle. At this time, the pull rope 11 is pulled during the rotation of the rotating ring 3, and the pull rope 11 drives the block 10 to enter the block groove 13, releases the clamping of the block 10 and the groove of the mounting block 6, and then removes the mounting clamp 5 to replace the nuclear pore membrane. Compared with the disassembly of the buckle clamp with pre-tightening force, it is more labor-saving and convenient.

[0035] In one embodiment, Figure 6 and Figure 7 As shown, the inner side wall of the block groove 13 is rotatably connected with a fixed pulley 12 through a pin shaft, and the pull rope 11 passes around the fixed pulley 12. The fixed pulley 12 can change the direction of the force of the pull rope 11.

[0036] Example 2

[0037] In one embodiment, Figure 3 As shown, the side wall of the rotating ring 3 is fixedly connected to two fixed handles 4, so that the rotating ring 3 can be rotated more conveniently by hand.

[0038] In one embodiment, Figure 1 and Figure 2 As shown, the side wall of the fixing plate 1 is provided with hollow air holes for convenient ventilation.

[0039] The above embodiment discloses a nuclear pore membrane assembly. When the entire nuclear pore membrane assembly needs to be installed on a fruit and vegetable safe box, it is only necessary to place the fixing plate 1 and the fixing ring 2 on both sides of the fresh-keeping box hole, and the installation can be completed by threading the first threaded cylinder 7 and the second threaded cylinder 8. The operation is quick and convenient.

[0040] When the nuclear pore membrane needs to be installed between the fixed plate 1 and the fixed ring 2, the nuclear pore membrane is first placed in the fixed ring 2, and then the four mounting blocks 6 of the mounting clamp 5 are pressed into the mounting block grooves. At this time, the installation can be completed by the clamping block 10 and the damping spring cooperating with the groove of the mounting block 6. The installation process is fast, convenient and labor-saving.

[0041] Since the side wall of the clamping block 10 is provided with a chamfer, the clamping block 10 and the mounting block 6 are clamped together more smoothly, and the wear of the clamping block 10 is reduced.

[0042] When the nuclear pore membrane needs to be disassembled and replaced, two fingers touch the fixed handle 4 and rotate the rotating ring 3 in any direction for a certain angle. At this time, the pull rope 11 is pulled during the rotation of the rotating ring 3, and the pull rope 11 drives the clamping block 10 to enter the clamping block groove 13, releasing the clamping connection between the clamping block 10 and the groove of the mounting block 6, and then the mounting clamp 5 is removed to replace the nuclear pore membrane. Compared with the disassembly of the clamping operation with pre-tightening force, it is more labor-saving and convenient.
