Description

Technical Field

[0001] This utility model relates to the field of isolation and sealing test chambers, and in particular to an isolation and sealing device for cable laying through walls in isolation and sealing test chambers. Background Technology

[0002] The industrial and medical fields involve numerous sealed testing chambers, but cable penetration through walls is unavoidable. Sometimes, hundreds of cables pass through the same location, creating numerous gaps between them. This results in incomplete sealing, internal and external communication, affecting normal user operation and potentially causing personal injury and environmental pollution. For example, leaks in high-level biological testing chambers can cause environmental biological contamination and personnel injury. Cleanrooms in electronics factories can affect indoor cleanliness and temperature / humidity; large temperature differences between indoors and outdoors can cause condensation and frost, and in severe cases, freezing. Cable laying is a common and critical task. However, traditional cable laying methods often compromise the airtightness of sealed testing chambers, consequently affecting environmental control and the accuracy of test results. Therefore, a device is needed that optimizes cable laying without compromising airtightness. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 In this embodiment of the invention, an isolation and sealing device 100 for cable penetration through a wall in an isolation and sealing test chamber includes: multiple hollow flexible sealing rods 21, multiple solid flexible sealing rods 22, and a flexible outer tube 10. The flexible outer tube 10 passes through the wall. The end faces of both the hollow flexible sealing rods 21 and the solid flexible sealing rods 22 are identical regular hexagonal structures. The hollow flexible sealing rods 21 have through holes 211. Cables pass through the through holes 211. The through holes 211 conform to the shape of the cables. The walls of the through holes 211 of the hollow flexible sealing rods 21 are cut off to form a ring with the ends joined together. The multiple hollow flexible sealing rods 21 and the multiple solid flexible sealing rods 22 are combined to form a hexagonal honeycomb structure 20.

[0022] The inner wall of the flexible outer tube 10 fits into the hexagonal honeycomb structure 20. The outer wall of the flexible outer tube 10 fits into the inner wall of the through-hole in the wall. The flexible outer tube 10 surrounds and wraps around the hexagonal honeycomb structure 20. The hole wall of the flexible outer tube 10 is cut off to form a ring with its ends joined together. The flexible outer tube 10 passes through the through-hole. In the length direction, both ends of the hexagonal honeycomb structure 20 protrude from the flexible outer tube 10.

[0023] As one specific implementation, an isolation and sealing device 100 for cable penetration through a wall in an isolation and sealing test chamber further includes: a mesh fabric. A hexagonal honeycomb structure 20 protrudes from both ends of the flexible outer sheath 10 and is wrapped with the mesh fabric.

[0024] As one specific implementation, an isolation and sealing device 100 for cable penetration through walls in an isolation and sealing test chamber further includes: a cable rack. The cable rack wraps around the mesh fabric and the hexagonal honeycomb structure 20 and supports the mesh fabric and the hexagonal honeycomb structure 20.

[0025] In one specific implementation, self-attracting magnets are provided at both ends of the annular joint where the hollow flexible sealing rod 21 is joined. Alternatively, self-attracting magnets may not be provided at the joint of the hollow flexible sealing rod 21.

[0026] In a preferred embodiment, the outer wall surface of the flexible outer tube 10 and the wall surface of the adapted through-wall hole are both cylindrical surfaces. The inner wall surface of the wire hole 211 and the outer wall surface of the adapted cable are also cylindrical surfaces. Using a cylindrical surface fit provides better sealing. Alternatively, other surface shapes can be used as needed.

[0027] In use, the cables are first wrapped one by one with hollow flexible sealing rods 21. Then, based on the number of cables, solid flexible sealing rods 22 are used to complete the hexagonal honeycomb structure 20. For the hexagonal honeycomb structure 20, the hollow flexible sealing rods 21 wrapping the cables are placed in the center first, and then the solid flexible sealing rods 22 are used to wrap around the hollow flexible sealing rods 21. The hexagonal honeycomb structure 20 is initially defined by a mesh fabric and / or cable tray, and then the hexagonal honeycomb structure 20 is wrapped with a flexible outer tube 10, which is then inserted into the through-hole in the wall. Installation requires ensuring that both ends of the flexible outer tube 10 protrude from both sides of the wall.

[0028] During assembly, sealant can be applied to the inner and outer walls of the flexible outer tube 10 as needed.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims. Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
