AI Technical Summary

Technical Problem

The existing pre-embedded junction box sealing device is prone to causing mortar to enter the junction box opening during the plastering process, resulting in a rough and uneven junction box opening, which affects the installation operation of the junction box.

Method used

The pre-embedded junction box closing device includes a closing contact component and an auxiliary support component. The contact plate and support plate precisely fit the side wall of the junction box window to prevent mortar from entering, and the position is adjusted by the contact screw and drive screw hole to maintain stability.

Benefits of technology

Ensure that the openings of the junction box windows are neat and uniform, so that the plastering can be quickly finished, facilitating the later installation of the junction box and avoiding rework.
