Abstract
The utility model relates to a profile obtuse angle connecting structure without a connecting part, which comprises a first profile and a second profile. The connecting edges of the first profile and the second profile present an obtuse angle; the connecting edges comprise a first contact edge, a middle contact edge and a third contact edge; the end edge of the first contact edge forms a lock port; the middle contact edge is formed by jointing the surface of the first profile and the surface of the second profile together; and the third contact edge forms clamping buckle connection. The advantages of the connecting structure are as follows: firstly, the first contact edge end edges of the two profiles form lock port connection, and the third contact edges form buckle connection without secondary processing or connecting parts; secondly, the cross section shapes at the lock port and the clamping buckle part for the two profiles are formed when the profiles are in pull molding, meanwhile, the installation efficiency is high, and the profiles can be recycled after removing; thirdly, the connecting structure passes through the whole connecting length of the first profile and the second profile, has large bonding strength and good overall rigidity, and is not easy to deform and damage.
Description
Technical field:
The utility model relates to a kind of section bar fast joint structure technology, more specifically to a kind of section bar obtuse angle syndeton of not having connector.
Background technology:
As everyone knows, aluminium alloy extrusions is widely used in making the member of door, window, shower house, and when utilizing these members to be barricaded as frame construction, usually the way that adopts is that connector adds screw and realizes entire combination, and wherein the obtuse angle for section bar connects more difficult.This connector adds the combining structure weak point of screw and is in the obtuse angle of section bar connects: one, and bonding strength is poor, needs the high connector of configuration bonding strength, and is moulded poor; Its two, need on-the-spot combination construction, time-consuming; Its three, during construction because of boring, profile structure is destroyed, and can't utilize after the dismounting again, causes waste.
The utility model content:
The purpose of this utility model provides a kind of do not have connector, section bar obtuse angle that can directly install fast, that bonding strength is high syndeton at the prior art weak point.
The purpose of this utility model is to realize by following measure: a kind of section bar obtuse angle syndeton, comprise first section bar, second section bar, it is characterized in that: the fillet of described first section bar and second section bar in obtuse angle, described fillet is followed successively by first contact edge, middle contact edge and the 3rd contact edge, the described first contact edge ora terminalis forms fore shaft, fore shaft is provided with the cross section by first section bar at the fore shaft place be turning back of semicircle arcuation, second section bar is that the forked hollow cylinder of opening is formed in ora terminalis cross section, fore shaft place, the semicircle arcuation of first section bar is turned back and is wrapped in the forked hollow cylinder appearance of the second section bar opening, contact edge is that the surface of first section bar and the surface of second section bar fit together in the middle of described, described the 3rd contact edge constitutes buckle and connects, buckle is made up of the bayonet socket of flange on second section bar the 3rd contact edge and first section bar the 3rd contact edge, and the flange of second section bar is buckled in the bayonet socket of first section bar.
Compared with prior art, owing to adopted the section bar fast joint structure that the utility model proposes, its advantage is as follows: 1) the first contact edge ora terminalis by two section bars forms the fore shaft connection, and the 3rd contact edge forms buckle and connects, and need not secondary operations or connector; 2) two section bars form when section bar draws moulding at the cross sectional shape at fore shaft and buckle place, and the installation effectiveness height is removed the back section bar and reclaimed use; 3) connection is applied on the whole connection length of first section bar and second section bar, and bond strength is big, integral rigidity good, is difficult for distorting, damaging.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1 has provided the structural representation of the utility model embodiment.Among the figure, a kind of section bar obtuse angle syndeton, comprise first section bar 1, second section bar 2, the fillet of described first section bar 1 and second section bar 2 in obtuse angle, described fillet is followed successively by first contact edge 4, middle contact edge and the 3rd contact edge 3, the described first contact edge ora terminalis forms fore shaft 5, fore shaft is provided with the cross section by first section bar at the fore shaft place be that the turning back of semicircle arcuation 51, second section bar 2 are that the forked hollow cylinder 52 of opening is formed in ora terminalis cross section, fore shaft place, and the semicircle arcuation 51 of first section bar 1 is turned back and is wrapped in forked hollow cylinder 52 appearances of second section bar, 2 openings; Contact edge is that the surface of first section bar 1 and the surface of second section bar 2 fit together in the middle of described, described the 3rd contact edge 3 constitutes buckle 6 and connects, buckle is made up of the bayonet socket 61 of flange 62 on second section bar the 3rd contact edge and first section bar the 3rd contact edge, and the flange 62 of second section bar is buckled in the bayonet socket 61 of first section bar.
When the utility model section bar connects, the forked hollow cylinder of the opening of second section bar is inserted in the turning back of semicircle arcuation of first section bar, rotate second section bar then and be buckled in the bayonet socket of first section bar the 3rd contact edge until the flange of second section bar the 3rd contact edge, this moment, the middle contact edge of first section bar and second section bar fit together.
The foregoing description does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
