Abstract
The invention discloses a folding type offtrack-proof guide rail for a non-wheeltrack electric retractable door. The guide rail adopts folding guide rail plates which have the same width as a neutral gear inside a door body; and each door leaf is provided with one plate inside along the moving direction of the door body. The folding guide rail plates are connected together through a turning pair; and the turning pair and a door body limit are integrated into a whole through a rotating shaft, which ensures that the folding guide rail is of a wave shape, so that a three-dimensional box-shaped load-carrying structure is formed, and the stretching direction of the structure is consistent with the moving direction of the door body. When the door body is stretched, the folding guide rail is closed and opened along the stretch of the door body and provides enough rigidity to prevent the offtrack of the door body. If the folding guide rail is used together with an electric door head capable of laterally adjusting displacement, the offtrack resistance can be further improved.
Description
Technical field
The present invention relates to a kind of passing through and improve the electric extension door integral rigidity, thereby prevent from not having the folding guide rail of wheel track electric extension door sideslip.
Background technology
At present, magnetic navigation and flexible rail technology are mainly adopted in the anti-deviation measure of electric extendable door of no wheel track guiding.Magnetic navigation not only needs the comparatively spy magnetic device of complexity, poor reliability, and can not save necessary on-the-spot civil engineering workload; Flexible rail then is to have utilized the telescopic guide rail of multilayer of high rigidity to prevent door body sideslip, but because there is the gap between layer and the layer in the flexible rail of multilayer, so when the door body is longer, can not obtain good straightness accuracy.Simultaneously, for the gap between key-course and the layer, have bigger frictional force between the flexible rail of multilayer, noise and wearing and tearing are inevitable in actual use.
Summary of the invention
In order to overcome the deficiency of the existing anti-deviation measure of non-wheeltrack electric retractable door, patent of the present invention has proposed a kind of folding guide rail.This folding guide rail has obtained higher lateral stiffness by three-dimensional box-shaped load-carrying construction, thereby prevents the whole sideslip of electric door body.Patent of the present invention has simple in structure, and is easy for installation, reliability height, advantage such as consistent with door body motion morphology.Can effectively improve the installation effectiveness of electric extendable door and anti-deviation effect.
The scheme that patent of the present invention substitutes the anti-deviation measure of existing non-wheeltrack electric retractable door is: a kind of retractable door folding type offtrack-proof guide rail, it comprises the folding guide device, revolute pair 2, rotating shaft 3, it is characterized in that: described folding guide device is by two blocks of folding guide plates 5,6 form, described folding guide plate 5 is linked together by described revolute pair 2 with folding guide plate 6 middle parts, body is spacing becomes one by rotating shaft 3 and door at revolute pair 2 places, and each folding guide device also links to each other with rotating shaft by revolute pair with the upper and lower of the folding guide device that adjoins.
The beneficial effect of patent of the present invention is in electric extendable door directed movement control field, by the novel folding guide rail of high rigidity is provided, need not the civil engineering working link in the electric extendable door erecting bed, has improved installation effectiveness, has reduced installation cost.Because folding guide rail has improved the integral rigidity of door body, door body self has the characteristics of directed movement, thus can save complicated magnetic navigation device, thus improved the reliability of the directed guided procedure of door body.
Description of drawings
Fig. 1 is the perspective view of the embodiment of the invention.
Fig. 2 is the planar side view of the embodiment of the invention.
Among the figure, 1 is the folding guide device, and 5,6 is collapsible guided plate, and 2 is revolute pair, and 3 are rotating shaft, and 4 is three-dimensional box-shaped load-carrying construction
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
As shown in Figure 1, the perspective view of the embodiment of the invention, Fig. 2 is its planar side view.
Adopt with the interior neutral of door body with wide folding guide plate 5,6, along arranging a slice in each door leaf of the door body direction of motion.These folding guide plates 5,6 are linked together by revolute pair 2 form folding guide device 1, body is spacing becomes one by rotating shaft 3 and door at revolute pair 2 places, thereby forms three-dimensional box-shaped load-carrying construction 4.The flexible direction of folding guide rail is consistent with the direction of motion of door body.When the door body was flexible, this folding guide rail is folding thereupon also, and provided enough rigidity in case door body sideslip.But this folding guide rail can make anti-deviation performance further promote as uniting use in conjunction with the electric door head of lateral displacement adjustment.
This guide rail provides high rigidity three-dimensional box-shaped load-carrying construction, can keep the straightness accuracy of door body in the electric extension door motion process, thereby realizes preventing a body sideslip.This guide rail is simple in structure, and rigidity is big, and its folded form is consistent with the flexible form of door body, has the effect that synthesizes one with the door body, so structure is attractive in appearance, and to no extra requirement is installed.The alternative existing wheel track of the use of this folding guide rail, thus the civil engineering working link when having saved on-the-spot install improves installation effectiveness, and installation cost descends.
Though the present invention with preferred embodiment openly as above; but they are not to limit the present invention; anyly be familiar with this skill person; without departing from the spirit and scope of the invention; from when can doing various variations or retouching, so being as the criterion of should being defined with the application's claim protection domain of protection scope of the present invention.
