[0028] Through-wall bushings with modular quick-install flanges, such as Figures 1-3As shown, the device includes a through-wall bushing body 10, on which a quick-connect flange 20 is mounted. A quick-connect ring 30, which engages with the through-wall bushing body 10, is mounted on the flange 20. The quick-connect ring 30 and flange 20 are integrally formed, with both having an L-shaped cross-section. The quick-connect ring 30 is connected to the outer wall of the through-wall bushing body 10 by at least two sets of wing bolts 31. The through-wall bushing body 10 has a built-in wire positioning seat 40 for fixing wires. The wire positioning seat 40 has several sets of axial wire insertion ports 42. The through-wall sleeve body 10 provides basic through-wall functionality and includes a built-in wire positioning seat 40. Several axial wire insertion ports 42 on the wire positioning seat 40 allow for secure insertion and positioning of the wires, improving wiring neatness and safety. The quick-release ring 30 and flange 20 are integrally formed, making installation more convenient. The L-shaped cross-section design enhances connection stability. The use of wing bolts 31 further improves the tightness and reliability of the connection between the flange 20 and the through-wall sleeve body 10, ensuring the stability and durability of the entire device.

[0029] Furthermore, the through-wall bushing body 10 includes a metal inner core 11, and an insulating inner layer 12 is provided on the inner wall of the metal inner core 11. The metal inner core 11 provides structural strength, while the insulating inner layer 12 on the inner wall of the metal inner core 11 can prevent current leakage and ensure electrical safety.

[0030] Specifically, the surface of the metal inner core 11 is provided with an anti-corrosion coating 13. The anti-corrosion coating 13 is an anti-corrosion paint layer with a thickness of 0.25-0.5mm. The anti-corrosion coating 13 provided on the surface of the metal inner core 11 can effectively prevent the metal inner core 11 from being corroded by the external environment and extend the service life of the through-wall bushing body 10.

[0031] The flange 20 has a shock-absorbing pad 22 on one side surface and several sets of evenly spaced fixing holes 21 on the flange 20. The shock-absorbing pad 22 on one side surface of the flange 20 can reduce the transmission of vibration generated during equipment operation. The evenly spaced fixing holes 21 on the flange 20 facilitate the use of bolts and other fasteners for fixing and connecting with other components.

[0032] In addition, a sealing gasket 41 that matches the inner diameter of the through-wall bushing body 10 is provided on the outer wall of the wire positioning seat 40. The thickness of the sealing gasket 41 is 2-3mm, and the sealing gasket 41 slides with the inner wall of the through-wall bushing body 10 with interference fit. By providing the sealing gasket 41 on the outer wall of the wire positioning seat 40 and matching the inner diameter of the through-wall bushing body 10, the sealing between the wire positioning seat 40 and the inner wall of the through-wall bushing body 10 is ensured, preventing external dust, moisture and other substances from entering. At the same time, the interference fit design ensures the stability of the wire positioning seat 40 during installation.

[0033] The working principle of this through-wall sleeve with modular quick-install flange:

[0034] First, begin installation by passing the wire through the wire socket 42 on the wire positioning seat 40 for initial positioning. Then, insert the entire component with the wire positioning seat 40 into the wall sleeve body 10 and ensure a seal by using the interference fit between the sealing gasket 41 and the inner wall of the wall sleeve body 10.

[0035] Next, install the flange 20, align the flange 20 with the quick-connect ring 30 with the through-wall sleeve body 10, fix the quick-connect ring 30 to the outer wall of the through-wall sleeve body 10 with the wing bolt 31, and tighten the wing bolt 31 to complete the connection.

[0036] Finally, bolts are used to pass through the fixing holes 21 on the flange 20 to connect and fix the wall bushing to other equipment. The shock-absorbing pad 22 can reduce the impact of vibration during operation. During use, the metal inner core 11 provides structural support and conductivity, the insulating inner layer 12 ensures insulation safety, and the anti-corrosion coating 13 protects the metal inner core 11 from corrosion, thereby ensuring the stable operation of the wall bushing and the orderly transmission of wires.
