Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a building window ventilation structure. Background Art

[0002] The ventilation structure can adjust the indoor and outdoor air circulation according to environmental changes and needs to achieve the purpose of energy saving and improving the indoor environmental quality. Mechanical ventilation usually uses ventilation windows, which are also called breathing windows and air exchange windows. However, the existing devices have certain disadvantages. For example, a building energy-saving ventilation structure recorded in the publication number CN220669686U relates to the technical field of ventilation structures. The building energy-saving ventilation structure includes a ventilation window frame, a slide groove is provided on the side of the ventilation window frame, a rotating rod is rotatably and slidably connected inside the slide groove, a windshield cloth is fixedly connected inside the ventilation window frame, a baffle is fixedly connected inside the ventilation window frame, a cloth clamping device is fixedly connected inside the ventilation window frame, a handle is fixedly connected to the side of the rotating rod, and a caliper wheel is fixedly connected to the surface of the rotating rod;

[0003] Although the above device adjusts the distance between the windshield and the baffle to control the size of the air outlet, it is not convenient to adjust the opening position of the window glass according to the external wind direction, which affects the ventilation capacity of the device. At the same time, the device lacks a quick-release structure, which is not convenient for quick disassembly of the device. Utility Model Content

[0004] The utility model aims to provide a building window ventilation structure to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, a hole No. 1 is provided on the front surface of the protective cover.

[0008] Furthermore, the front surface of the mounting plate is provided with mounting holes near the four corners, and the front surface of the mounting plate is provided with a second hole near the center.

[0009] Furthermore, a worm is fixedly connected to the output end of the mounting seat, a worm wheel is fixedly connected to the outer surface of the rotating shaft, and the worm and the worm wheel are meshingly connected.

[0011] Furthermore, the outer surface of the rotating disk is fixedly connected to a limiting track, and the extrusion wheel is rollingly connected to the limiting track.

[0012] Furthermore, one end of the double-headed screw is fixedly connected to a hexagonal column, and the other end of the double-headed screw is fixedly connected to a synchronous wheel. The number of the synchronous wheels is two, and the outer surfaces of the two synchronous wheels are nested and connected with synchronous belts.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Start the stepper motor through the rotating disk. The output end of the stepper motor drives the worm to rotate, so that the worm cooperates with the worm wheel to drive the gear on the rotating shaft to rotate. The gear drives the ring gear to rotate, and the ring gear drives the rotating disk to rotate, so that the opening and closing direction of the window glass is changed, and the ventilation capacity of the device in different wind directions is improved.

[0015] 2. Through the L-shaped seat, use an electric wrench and a hexagonal column to rotate one of the double-headed screws.

Under the push of the thread, the two extrusion seats move outward to separate the extrusion wheel and the rotating disk, so that the rotating disk loses its external fixation, which is convenient for the later disassembly of the rotating disk and further facilitates the replacement of the window glass.
