Description

Technical Field

[0001] The utility model relates to the technical field of electric window openers, in particular to a screw-type electric window opener. Background Art

[0002] At present, windows in buildings are opened or closed electrically, and windows can be opened or closed quickly. At the same time, they can be remotely controlled to ventilate the building. For example, the fire-fighting electric window opener disclosed in Chinese patent literature (patent number: CN201822028894.1) uses an electric window opener to open or close the window, but the electric window opener cannot be quickly disassembled and replaced. If there is a problem with the electric window opener, the window cannot be opened or closed. The electric window opener is used for ventilation in buildings or factory buildings, which will affect ventilation. If the electric window opener is used on the side walls of buildings and factory buildings and at a low height, it is relatively easy to repair the electric window opener. Repairing the electric window opener requires moving time. If the electric window opener is used on the top of a building or factory building, the position and height of the electric window opener will be inconvenient for maintenance. Even if it is repaired, the maintenance personnel will be at a high height for a long time, affecting the work safety of the maintenance personnel.

[0003] For this reason, we propose a screw-type electric window opener. Utility Model Content

When the clamping block is received in the placement slot, the electric screw is moved to the left, and the electric screw drives the mounting plate to move. At the same time, the electric screw drives the positioning plate to move to the left. After the positioning plate is separated from the positioning port, the electric screw is moved upward, and the electric screw drives the mounting plate to separate from the mounting slot. When the bottom of the electric screw is disassembled, the top of the electric screw is disassembled at the same time, so that the electric screw can be moved, and the electric screw can be quickly disassembled and installed. The threaded rod pushes the clamping block to move, and the clamping block is stuck in the main clamping port. The threaded rod continues to be rotated, and the threaded rod pushes the mounting plate to move through the clamping block. The positioning plate arranged on the right side of the mounting plate is installed in the positioning port, and the mounting plate is quickly fixed to complete the rapid replacement of the electric screw.
