Abstract
The invention discloses a chain track for a window opener, which belongs to the field of window openers. The chain track comprises a chain output port (1), a worm part (2), a worm wheel part (3), a chain-driven chain wheel part (4), a chain-assisted turning mechanism (5), a track tail end (6) and a chain track wall (7). The chain track is suitable for contracting all the current anti-bending chains as well as ordinary chains. The chain track manufactured by adopting the chain track having the structure has the advantages that the total length of the window opener is small; moreover, the track plays an excellent role in a scheme of the need of longer travel under the condition of limited window width.
Description
Technical field
The present invention relates to a kind of track, specifically a kind of window opener chain track.
Background technology
Window opening device has been used to fire-fighting smoke exhaust system, the opening and closing of high-rise window, the occasions such as Smart Home widely.Fast development along with modern architecture, its designed window type is also all multiple types, particularly for large stadium, need the window design of natural draught system, its window size is relatively large, for meeting large-area ventilation smoke exhaust requirement, needs window to open longer stroke, but, for the window frame than narrow dimension, can't meet the installation of the longer stroke of traditional window opening device.
Summary of the invention
The problem existed for above-mentioned prior art, the invention provides a kind of window opening device chain track, can be in the window frame size of relative narrower, by chain, in specific track, repeatedly turn, make chain take full advantage of the inner space of its aluminium extruded sections or injection mold, realize equal limit size, the purpose that stroke is the longest with this.
To achieve these goals, the technical solution used in the present invention is: a kind of window opener chain track, the auxiliary turning mechanism of chain drive sprocket wheel, worm-and-wheel gear, chain and chain is housed in described chain track shell, chain is on chain drive sprocket wheel, chain drive sprocket wheel is connected with turbine, worm screw connects an external crank handle, there is the chain delivery outlet at chain track section bar shell place, and chain one end assists turning mechanism to assist turning from the output of chain equipped at outlet port, the chain other end by chain.
Assist the chain of turning structure by chain, utilize the hollow position of section bar an actor's rendering of an operatic tune according to its turning mechanism chain.
Turbine adopts the mode of duplex overlaying mechanism to be coordinated rotation with chain drive sprocket wheel.
The action of its chain is divided into chain output and two kinds of patterns of chain input, when worm screw passes through outside crank handle input torque, himself is rotated, engagement due to turbine and worm, turbine adopts the mode of duplex overlaying mechanism to be coordinated rotation with rear one-level sprocket wheel, controlling chain by hand suitable counterclockwise mode with this is gone out and the action of advancing, when chain movement is assisted the turning mechanism place to chain, the direction of circular arc guiding mechanism guiding chain movement, its pattern is divided into, chain arrives at track end from track output or chain fully can't continue motion.
With existing aluminium extruded sections, with injection mold window opening device chain track, compare: chain track of the present invention is not only applicable to the storage of all anti-bending chains at present, is applicable to takeing in of common chain simultaneously yet.Its advantage is to adopt the window opener of the chain track manufacturing of this kind of structure, and not only the overall length of window opener is little, and limited in window breadth, needs again in the longer scheme of stroke, and this type of track is being brought into play very outstanding effect.The core of this novel window opening device chain track just is the turning radius of chain the best of reasonable computation different model, is deeply that the machining accuracy of chain auxiliary guide mechanism is directly determining whether turning round smoothly of this mechanism.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structure of the auxiliary turning mechanism of chain.
In figure: 1, chain delivery outlet, 2. worm screw part, 3, the turbine part, 4, the chain drive sprocket wheel part, 5, the auxiliary turning mechanism of chain, 6, track end, 7, the chain track wall.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 1, shown in Fig. 2, a kind of novel window opening device chain track, comprise chain delivery outlet 1, worm screw part 2, turbine part 3, chain drive sprocket wheel part 4, the auxiliary turning mechanism 5 track end 6 chain track walls 7 of chain; When chain need to be exported, worm screw 2 is rotated, drives turbine 3, is rotated, turbine adopts the duplex overlaying mechanism to be coordinated with rear one-level sprocket wheel 4, controlling chain by hand suitable counterclockwise mode with this is gone out and the action of advancing, when chain movement is assisted turning mechanism 5 place to chain, due to its specific chain guiding mechanism, chain will not there will be stuck situation herein.Its core is the model according to every money chain, and Reasonable is calculated its limit turning radius, with this, determines the track that best chain is turned.
This kind of novel window opener chain track that is loaded with chain is divided into two kinds of duties:
Chain is from the track output state: when being provided by previous stage turbine and worm when selecting motion counterclockwise, due to the moment of torsion transfer function of transmission, its moment of torsion will be delivered to chain itself by sprocket wheel.When chain need to go out chain, counterclockwise swinging handle, chain, due to the effect that is rotated counterclockwise of its sprocket wheel, pulls out chain by it.Otherwise, select clockwise, due to turning clockwise of sprocket wheel, chain is reclaimed to track inside.Above all chains move smoothly and all are based on the reasonable computation that chain is assisted turning mechanism.
Window opener chain track of the present invention is not limited to the auxiliary utilization of turning mechanism 5 in this novel track of single chain, and the utilization of a plurality of chain auxiliary guide mechanism in same track is also the scope that belongs to protection in theory.The optimum turning radius of its theory based on narrow chain auxiliary guide mechanism, guarantee the smooth running of this mechanism with this.
