Abstract

A window body with an opening and closing type vent hole is disclosed, comprising a window body, a rotation switch, a seal ring, a rotating shaft, a baffle plate and a spring, characterized in that the window body is provided with a pore, the seal ring is fixed at outer edge of the pore of indoor window body, the baffle plate is located at the pore of the indoor window body, the window body at lower back position of the baffle plate is connected with the spring, front, back ends of the baffle plate are respectively provided with a front slide way and a back slide way, the rotating shaft is parallel to and fixed on the window body and can slide within the back slide way after passing through the back slide way, the rotation switch is in shape of bolt and in screw thread connection with a prearranged hole with the screw thread along the front slide way which inserts through the baffle plate in a direction vertical to the window body. By using the utility model, direct flow is not formed when air flow encounters the baffle plate prior to entering the room, which guarantees the indoor temperature; opening size of the baffle plate can be adjusted, the air exchange is mild and can be achieved without opening the window, thus the utility model is secure, reliable, convenient and practical.

Description

The forms that have the open-shut type air vent

Technical field:

The utility model belongs to a kind of external window of building with air vent.

Background technology:

Along with the raising of living standards of the people, people are more and more higher to the requirement of forms, not only will have good safety and thermal and insulating performance, wish also that room air is can be comparatively gentle logical to change, and improve IAQ (indoor air quality) and exceed and influence interior temperature.And forms such as traditional plastic-steel window or solid wood window all must be opened sash the purpose that just can reach the ventilation ventilation, and are so not only stolen easily, and very big to the interior temperature influence.

Summary of the invention:

The purpose of this utility model provides a kind of simple in structure, and ventilation is gentle, a kind of forms that have the open-shut type air vent that ventilation volume is adjustable.The technical solution of the utility model is: the utility model comprises forms, revolution switch, sealing ring, rotating shaft, plate washer, spring, be characterized in: have hole on the forms, sealing ring is fixed on the hole outward flange of indoor forms, plate washer is positioned at the hole place of indoor forms, below plate washer, be connected with spring by on the forms of back-end location, the front end of plate washer has preceding chute, the rear end has the back chute, shaft parallel is in forms and be fixed on the forms, it passes the back chute on the plate washer, can slide in the chute of back, revolution switch is a bolt shape, and its edge inserted the preceding chute of plate washer perpendicular to the forms direction and the threaded preformed hole on the forms is threaded togather.The utility model air flue runs through forms thickness, and can be arranged on any position of forms; Run into baffle plate before in the air-flow inlet chamber and do not produce direct current; In the air communication air passing hole pipe inlet chamber, air inlet port was shut during flapper closure, can guarantee interior temperature when baffle plate was opened, baffle plate is opened adjustable size, can control stomatal movement indoor, and ventilation is gentle, need not window to reach the ventilation purpose, safe and reliable, convenient and practical.
