Abstract
The utility model discloses an electric telescopic door elbow component which comprises an aluminum alloy straight pipe and plastic elbow frames. Two ends of the aluminum alloy straight pole are oblique end surfaces, and a plastic elbow frame is connected with each oblique end surface in butt joint mode. The aluminum alloy straight pipe is cut into a first arc-shaped shell body and a second arc-shaped shell body along a longitudinal direction, a clamping groove is arranged on the shell body wall, close to the cutting surface, of the first arc-shaped shell body, and a protrusion matched with the clamping groove is arranged on the shell body wall, close to the cutting surface, of the second arc-shaped shell body. Due to the fact that the aluminum alloy straight pipe is changed into a split type structure, the plastic elbow frames are enabled to be cast and moulded in one step in advance, the process of the electric telescopic door elbow component is simplified, the producing efficiency is improved, and the cost of the electric telescopic door elbow component is reduced. Corner decorative rings are sleeved on the butt portion of the aluminum alloy straight pipe and the plastic elbow frames, and therefore the aesthetic degree of the electric telescopic door elbow component is improved, meanwhile manufacturing accuracy requirements of the aluminum alloy straight pipe and the plastic elbow frames are reduced, and the pass rate of finished products is improved.
Description
Technical field
The utility model relates to the Black Warrior door elbow assembly on a kind of door of electric expansion door sheet.
Background technology
Black Warrior door elbow assembly is the connector that is used in door sheet switching place of electric extendable door, links together by this assembly between column, top rail and the lower transverse beam of door sheet, forms the door sheet of closed.
Black Warrior door elbow assembly generally is comprised of aluminium alloys straight tube and plastic elbow frame, and the two ends of aluminium alloys straight tube are respectively beveled end surface, docks respectively a plastic elbow frame at each beveled end surface place.Because the aluminium alloys straight tube is closed tubing, for the beveled end surface that guarantees the aluminium alloys straight tube and the merging precision of plastic elbow frame, need first with the machine-shaping of aluminium alloys straight tube, and then according to the size of aluminium alloys straight tube, the plastic elbow frame is carried out the second casting moulding.
Because the processing technology of existing Black Warrior door elbow assembly is comparatively complicated, and is higher to the requirement on machining accuracy of aluminium alloys straight tube and plastic elbow frame, so that the cost of Black Warrior door elbow assembly is higher.
Summary of the invention
Goal of the invention: the purpose of this utility model is to solve existing Black Warrior door elbow assembly complex manufacturing, and the problem that cost of production is high provides a kind of and can simplify production technology, the Black Warrior door elbow modular construction that reduces production costs.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of Black Warrior door elbow assembly, comprise aluminium alloys straight tube and plastic elbow frame, the two ends of described aluminium alloys straight tube are respectively beveled end surface, dock respectively a plastic elbow frame at each beveled end surface place, the longitudinally cutting of described aluminium alloys straight tube is the first arcuation housing and the second arcuation housing, described the first arcuation housing is provided with draw-in groove near the housing wall of cutting face, housing wall at the close cutting face of the second arcuation housing is provided with the projection suitable with draw-in groove, and described the first arcuation housing and the second arcuation housing are connected together mutually by draw-in groove, projection.
In the utility model, further, the joint of described beveled end surface and plastic elbow frame is arranged with the corner rosette.
In the utility model, further, described draw-in groove is along vertical perforation of the first arcuation housing.
Compare with existing Black Warrior door elbow assembly, the utlity model has following characteristics:
(1) owing to make the aluminium alloys straight tube into split-type structural, so that the in advance cast molding of plastic elbow frame makes the work simplification of Black Warrior door elbow assembly thus, production efficiency improves, and has reduced the cost of Black Warrior door elbow assembly;
(2) be arranged with the corner rosette at aluminium alloys straight tube and plastic elbow frame joint, not only can improve the aesthetics of Black Warrior door elbow assembly, also reduced aluminium alloys straight tube and plastic elbow frame requirement on machining accuracy simultaneously, the finished product qualification rate is increased;
(4) globality of product and intensity all are greatly improved;
(3) more convenient and quicker when assembling is used.
Description of drawings
Fig. 1 is structural front view of the present utility model;
Fig. 2 is that A-A among Fig. 1 is to sectional view;
Fig. 3 is structure side view of the present utility model;
Fig. 4 is that B-B among Fig. 3 is to sectional view.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figures 1 to 4, a kind of Black Warrior door elbow assembly of the present utility model comprises aluminium alloys straight tube and plastic elbow frame 1, the two ends of described aluminium alloys straight tube are respectively beveled end surface 2, dock respectively a plastic elbow frame 1 at each beveled end surface 2 place, the joint of beveled end surface 2 and plastic elbow frame 1 is arranged with corner rosette 7, the effect of corner rosette 7 is the aesthetics that improve Black Warrior door elbow assembly, has also reduced aluminium alloys straight tube and plastic elbow frame 1 requirement on machining accuracy simultaneously.The longitudinally cutting of described aluminium alloys straight tube is the first arcuation housing 3 and the second arcuation housing 4, and described the first arcuation housing 3 is provided with draw-in groove 5 near the housing wall of cutting face, and described draw-in groove 5 is along vertical perforation of the first arcuation housing 3; Be provided with the projection 6 suitable with draw-in groove 5 at the second arcuation housing 4 near the housing wall of cutting faces, described the first arcuation housing 3 and the second arcuation housing 4 are connected together mutually by draw-in groove 5, projection 6.Owing to make the aluminium alloys straight tube into split-type structural, so that an in advance cast molding of plastic elbow frame 1 makes the work simplification of Black Warrior door elbow assembly thus, production efficiency improves, and has reduced the cost of Black Warrior door elbow assembly.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
