Description
Technical field
The present invention relates to building consumptive material technical fields, and in particular to a kind of window-frame convenient to use.
Background technique
It needs to complete using many building consumptive materials so as to which assembly will be built in the building of building.Wherein, window-frame is made
Bracket for window is a kind of important building consumptive material, has what the support of window-frame was just able to satisfy user to carry out daily adopt by window
Light, guarantees indoor bright and clear and with fresh air etc., therefore window-frame is of crucial importance,
Traditional window is all to be made up of fixed window-frame, sash and hinge, and hinge connects as window-frame and sash
It connects, window-frame is rotated into hinge as fulcrum and sash is driven to close or open to control window, and hinge uses overlong time oxygen
Change can generate a large amount of rusty stain and hinge is easily damaged, while also needing to design one and supporting the opening for being used to support sash,
This window is inconvenient to use.Occurs aluminum window with the development of technology, which is connect by window-frame with window sash slides, is led to
The opening and closing of window can also be realized by crossing the sliding window on window-frame, so that it is convenient and efficient to reduce operation sequence.But two
The all unavoidable needs of kind window are manually operated, and when people do not need to open a window indoors or close window, window can not be automatic
It opens or closes.
Summary of the invention
Drill bit can be improved the purpose of the present invention is to provide one kind and carry out preliminary working drilling or finishing drilling cooling effect
Drilling cooling device.
In order to achieve the above objectives, it the technical scheme is that a kind of window-frame convenient to use, including window-frame and can close
Window-frame and parallel the first sash and the second sash, the second sash are fixed on window-frame, is equipped between the window-frame two sides and fixes
On window-frame and the scraper plate that can be bonded with the first sash, first sash bot-tom are all provided with fluted and ball, the ball peace
Loaded in groove, the window-frame bottom is equipped with slideway parallel and for ball sliding, and slideway one end is segmental arc, in segmental arc
Equipped with the first slide plate, it being equipped with power unit below the slideway, the power unit includes first inner chamber and second inner chamber, and first
Inner cavity is fixedly installed with the controllable cylinder being fixedly connected with the first slide plate, and first inner chamber side is equipped with compression chamber, sets in compression chamber
There is the second slide plate being fixedly connected with the first slide plate, the gas that pressure switch is fixedly installed in second inner chamber and is connected to outside
Capsule, pressure switch are connect with air bag, and pressure switch is electrically connected with controllable cylinder, and the window-frame bottom is fixed with air amplifier,
The air amplifier includes tracheae and the annular chamber for being fixed on tracheae periphery, and described tracheae one end is connected to outside, and tracheae is another
One end is connected to the stomata that window-frame one side wall is equipped with, and the wind blown out in stomata can push the first sash to slide on ball, annular
Chamber is equipped with the opening towards stomata, and the annular chamber is connected to the compression chamber below the second slide plate, and annular chamber is connected to compression chamber
Place is equipped with pressure valve, and compression chamber bottom is equipped with breather check valve.
The principle of the present invention: when the first sash of window is in the open state, ball can be fallen in segmental arc from groove,
When nobody closes and blows, wind can be poured into air bag, and air bag can expand and squeeze pressure switchs.Pressure switch can be held
Controllable cylinder is opened, so that controllable cylinder will push the first slide plate upward sliding, and the first slide plate will drive the second slide plate slides,
Second slide plate upward sliding can pass through breather check valve air inlet.First slide plate upward sliding will push the rolling fallen in segmental arc
Pearl.Ball can be slided by the motive force of the first slide plate along segmental arc, can enter groove by the ball rolling of segmental arc
It is interior, the first sash will drive by the effect ball of frictional force and close window-frame, to play the role of closing window.First window
Fan sliding when can pass through scraper plate, scraper plate can the surface to the first sash carry out scrape to play the role of clean the first sash.
When becalming only, indoor needs are ventilative.Gas in air bag can be run out of completely, and air bag will do it contraction.The gas of contraction
Capsule no longer squeeze pressure switchs, and pressure switch can close controllable cylinder.Controllable cylinder will drive the first slide plate and the second slide plate to
Lower slider, the second slide plate can pressurize the space of compression chamber below the second slide plate, and the gas below the second slide plate will receive extruding.
Pressure valve is opened to squeeze to which gas will form high pressure gas, the high pressure gas in compression chamber below the second slide plate passes through pressure
Power valve enters in annular chamber.High pressure gas is entered intratracheally by annular chamber from opening, so that tracheae forms high-speed flow
And a large amount of gas is sucked from outside, the gas that the gas of sucking can be gone out by stomata and from stomata can blow first
Sash.First sash is pushed ball by motive force, and ball drives the first window sash slides, and the first sash slips off to open
Window and the first sash resists window-frame side wall.When first sash is opened, ball can be entered in segmental arc.It does not need to control automatically
When close window processed, controllable cylinder power supply can be stopped, so as to the open and close of manual control window.
Beneficial effects of the present invention: (1) present invention pushes the closing of the first sash by ball, on the one hand facilitates supply
Power facilitates the sliding of the first sash when on the other hand also facilitating the first sash of artificial closing.
(2) cooperation for passing through air amplifier and compression chamber, window is opened, do not need that window is opened manually by air-flow
Family is convenient for people to use.
(3) sash can be carried out by scraper plate striking off cleaning, to reduce the work of manual cleaning sash.
On the above base case:
It advanced optimizes, the window-frame two sidewalls are equipped with buffer layer.First sash is buffered, to reduce the first window
Fan the probability of damage.
It advanced optimizes, the compression chamber above two second slide plate is equipped with the air flue being connected to segmental arc.Second is sliding
Plate, which compresses the fooled compression chamber of the second slide plate, to be dried by air flue to segmental arc, and the wind blown out can push ball, thus
Increase the power of ball.
It advanced optimizes, the scraper plate is doubling plate, is equipped with bristle between the doubling plate.Sash is by the double-deck clamping plate
When, bristle clears up sash, improves cleaning effect.
It advanced optimizes, the temperature-sensitive switch being electrically connected with controllable cylinder is equipped with inside and outside the window-frame.Temperature-sensitive switch impression
Variation to temperature can also control opening or closing for controllable cylinder, to reach the mesh that temperature change opens or closes window
's.
