Abstract

The present invention relates to a novel chain grate comprising an inner chain link and an outer chain link which are arranged at intervals and, and the heads and the tails of the inner chain link and the outer chain link can be rotatablely connected. The present invention is characterized in that two chain plates of the inner chain link and two chain plates of the outer chain link are all provided with wing plates in an extensive mode in the same direction, and the two wing plates of at least one of the inner chain link and the outer chain link are respectively bent and interlaced towards the wing plate at the same side of the other chain link. Compared with the prior art, because the chain plate of the chain link is additionally provided with the wing plates staggered with the chain plates of the adjacent chain link, the chain can be bent and can revolve around towards a direction, and the chain has the driving function of the ordinary chain. When the chain is in a straightening state, the whole of the chain presents rigidity, and thereby, objects connected to the tail end of the chain can be driven, so that the chain can become the main member of an object driver. The novel chain grate has the practical application that the chain is used for manufacturing an opening and closing driver of wing sashes of a casement window, and the chain is arranged on an upper frame or a lower frame of a window solely or in pairs. Compared with the prior art, the opening and closing driver of the wing sashes of the casement window can achieve the automatic opening and the closing of the wing sashes of the window breezily by using the novel chain of rigidity and flexibility, and the entire driver has the advantages of succinct structure and cabinet volume. The novel chain grate is suitable for industrial production.

Description

A kind of chain and application thereof

Technical field

The present invention relates to a kind of chain, particularly a kind ofly drive chain and the application thereof that is connected its terminal object.

Background technology

Chain is as a kind of traditional transmission mechanism, has simple in structure, the receiving state little characteristics that take up room, yet because traditional chain does not have rigidity characteristics, is not suitable as the driver of door and window wing or other objects.On the other hand, for existing casement window with rotary wing, its wing still is manual opening-closing mostly, in the patent of in the past announcing, also have and to disclose the casement window automatic opening-closing, but it drives the transmission of wing, driving mechanism still is confined to traditional design, as notification number is " a kind of the raining of CN2467723Y, the rain stop automatic closing, open the device of window " in what adopt is gear-rack gear, as notification number is that what adopt in " the grain depot automatic open and close window " of CN2489056Y is the worm Gear-Worm transmission mechanism, as notification number is that what adopt in " the vent window automatic open device " of CN2507972Y is cylinder-piston mechanism, or the like.These traditional wings rotarily open driver and all have complex structure, shortcoming that space hold is big.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of existing traditional transmission agency to have at above-mentioned prior art present situation can drive the chain that is connected its terminal object under its extended configuration.

Another technical problem to be solved by this invention is to utilize described chain and provide a kind of simple for structure, flat opening door and window wing that volume is small and exquisite to open and close driver.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this chain includes at interval and arranges, rotatable inner link and the outer link that links to each other of head and the tail, it is characterized in that two carrier bars of described inner link and two carrier bars of outer link all are extended with the wing plate on same direction, and the two wing plates of one of them are staggered towards the bending of homonymy wing plate and the formation of another chain link respectively at least in inner link and the outer link.

Described wing plate bending situation comprises following three kinds: 1. two wing plates of inner link bending outwardly respectively, and form staggered with the homonymy wing plate of outer link respectively; 2. two wing plates of outer link are respectively towards inner bending, and form staggered with the homonymy wing plate of inner link respectively; 3. respectively bending outwardly of two wing plates of inner link, and form staggered with the homonymy wing plate that bends inwards of outer link respectively.

Compared with prior art, the present invention is owing to set up on the carrier bar of chain link and the staggered wing plate of the carrier bar of adjacent link, therefore chain can unroll towards a direction bending, transmission agency with common chain, and when chain is in straight configuration, integral body presents rigidity, is connected its terminal object thereby can drive, and makes it can become the main member of object driver.

The application of a reality is to utilize described chain to make flat opening door and window wing to open and close driver, can include a storage chain storehouse, this storage chain storehouse have one be bent into the external splint of U type and be positioned at its inboard and with two inner splints of its two side planes partial parallel, arc tips at external splint is provided with a directive wheel, openend at external splint then is provided with a sprocket wheel, described chain promptly through guide wheel disk around between inner splint and the external splint, and its outer end goes out to store up the chain storehouse and is connected with the door and window wing through sprocket wheel.

Described sprocket wheel can have the manual or electronic rotation of ordering about by transmission mechanism, thereby makes the overhanging or retraction of chain, and the part that chain stretches out storage chain storehouse is rigidity because of stretching, thereby realizes the keying of door and window wing;

The motor drive mechanism of described drive sprocket can constitute by motor and with the worm reducer that motor power drives to sprocket wheel; The man-operated mechanism of described drive sprocket can constitute with the conical gear and the handle thereof of sprocket shaft engagement by one; Also motor drive mechanism and man-operated mechanism can be set simultaneously, and between the input of the output shaft of described worm reducer and sprocket shaft, a controlled engagement type mechanical clutch be set, to switch electronic or manual operation.

Described door and window wing driver can be single upper ledge or the lower frame that is arranged on door and window, also can be separately positioned on the upper and lower frames of door and window for a pair of, and makes two sprocket coaxiality settings, so that two chains of unified Synchronization Control is flexible.

Compared with prior art, flat opening door and window wing of the present invention opens and closes driver by utilizing the chain of " hard and soft double Ji ", not only realized the automatic open and close of door and window wing like a cork, and whole activation configuration is succinct, volume is small and exquisite, is fit to industrialized production.
