In the figure: the device comprises a shell 1, a bottom sealing cover 2, a first rack 3, a second rack 31, a first elliptical hole 32, a second rack 4, a first gear 41, a second elliptical hole 42, a gear 5, a limiting fixing column 6, a rotary fixing sheet 7, a fixing bottom sheet 8, an equal-height gasket 9, screws A10, screws B11, upper locking points 12, lower locking points 13, a handle 20, a wall 21, a window frame 22, a fan-shaped section 23, glass 24, a first locking seat 25, a second locking seat 26, a locking rod 27 and a driver 28.

Detailed Description

Referring to the drawings, the utility model relates to an aluminum alloy door and window ventilates mechanism a little, including casing 1, its characterized in that: a gear 5 is installed in the shell 1, a first rack 3 and a second rack 4 are respectively installed on two sides of the gear 5, and a second gear 31 or a first gear 41 is arranged at the end part of at least one

rack

3 or 4.

When the locking mechanism is installed and used, the locking point 12 can move above the rack 4 when the rack 4 is compressed, and the first gear 41 can prevent the locking point 12 from moving when the rack 4 extends out.

The gear 5 is driven to rotate by the telescopic motion of the first rack 3 or the second rack 4, and the rack on the other side is driven to move by the rotation of the gear.

The rotary fixing piece 7 is locked on the window frame 22 through screws.

In the embodiment of the present invention:

an elliptical hole 32 is formed in the first rack 3, and the limiting fixing column 6 penetrates through the elliptical hole 32 and is fixed on the shell 1. The movement of the rack 3 is limited and the shell 1 is fixed.

An elliptical hole 42 is formed in the second rack 4, and the limiting fixing column 6 penetrates through the second elliptical hole 42 and is fixed on the shell 1. The movement of the rack 4 is limited and the shell 1 is fixed.

The limiting fixing column 6 is of a hollow structure, and a gasket 9 with the same height is sleeved on the outer surface of the limiting fixing column.

Referring to fig. 7, the schematic view of the locking state of the window sash according to the present invention is shown. At this time, the first rack 3 is in a compressed state under the contraction action of the upper locking point 12 and realizes the locking of the locking point, and the lower locking point 13 is locked with the first lock seat 25.

Referring to fig. 8, when the handle 20 is rotated 90 degrees, the lower locking point 13 is separated from the first lock seat 25, and the upper locking point 12 is separated from the second gear 31 of the first rack 3, so that the window sash can be opened outwards.

Referring to fig. 9, after the window sash is opened to a certain angle, the upper locking point 12 is blocked by the first gear 41 of the second rack 4, and the window sash cannot be opened further, so that the danger that a child climbs out of the window and falls off can be prevented. The lower locking point 13 is in a disengaged position corresponding to the second locking seat 26. The sash open state is shown in fig. 10.

Referring to fig. 11, in the slightly outward opening state, the upper locking point 12 is located at a position corresponding to the first gear 41 of the second rack 4, the lower locking point 13 is located at a position corresponding to the second locking seat 26, the handle is rotated back to the original locking state, the second rack 4 is compressed by the locking point 12 to be locked, and the lower locking point 13 and the second locking seat 26 are locked, so that the slightly opening locking of the window is realized. Can achieve the effects of ventilation and air permeability and also can achieve the effect of theft prevention.

Referring to fig. 12, in the slightly opened state, the handle is rotated by 90 degrees, the upper locking point 12 is disengaged from the first gear 41 of the second rack 4, the lower locking point 13 is disengaged from the lock base 26, and the window sash can be opened outwards.

Referring to fig. 13, this is a state after the window sash is opened.

The utility model discloses the effect of implementing is for opening repeatedly and closing through twice handle, makes the casement open a little and can protect child mistake to open the danger that falls and also can realize the ventilation function a little, especially can realize ventilating a little under the sleep state at night, also can realize the theftproof function.
