Abstract
The utility model relates to section bar fastening technology, is specifically related to a kind of aluminium alloy extrusions circular arc fastener, it is characterized in that being made up of the first section bar, the second section bar and connecting rod; Connecting rod is snapped between the first section bar and the second section bar for " work " shape section bar respectively; The shape size of the first section bar and the second section bar matches; Be respectively equipped with a ball-shaped groove in the side of the first section bar and the second section bar, opposite side is respectively equipped with ball-shaped fastener; Described ball-shaped groove mates mutually with ball-shaped fastener; The ball-shaped fastener cover of the first section bar is buckled in the ball-shaped groove of Second-Type material; The ball-shaped fastener cover of the second section bar is buckled in the ball-shaped groove of the first section bar; Ball-shaped groove inner wall mutually coincide with ball-shaped fastener respectively and mutually against; And form cylinder slide rail, ease of assembly; The utility model utilizes the surface of contact of Surface of Sphere large, weares and teares minimum, and the minimum feature of resistance, as fastening, has efficiency when section bar is fastened high, quality surely, qualitative reliable superiority.
Description
Technical field
The utility model relates to architectural shape technical field, particularly a kind of aluminium alloy extrusions circular arc fastener.
Background technique
In prior art, the connection of aluminium alloy extrusions needs to be connected both by special link, and this link needs special instrument, and the cost of link is higher, and the aluminum alloy sealing after connection is strong not; The fastener of existing aluminium alloy extrusions mostly is card rib formula, there will be resistance phenomenon, thus increasing workload when fastening, and occurs connecting not docile sometimes, and bearing capacity is inadequate, makes the aluminium alloy extrusions after connection occur rocking.
Model utility content
The purpose of this utility model is the deficiency for present technology, thus provides a kind of efficiency high, and quality is steady, reliably qualitative, is applicable to the aluminium alloy extrusions circular arc fastener used without temperature and environment.
For achieving the above object, this practicality provides a kind of aluminium alloy extrusions circular arc fastener, and the utility model adopts a kind of aluminium alloy extrusions circular arc of following technological scheme fastener, it is characterized in that being made up of the first section bar (1), the second section bar (2) and connecting rod (3); Described connecting rod (3) is snapped between the first section bar (1) and the second section bar (2) for " work " shape section bar respectively; Described first section bar (1) matches with the shape size of the second section bar (2); Be respectively equipped with a ball-shaped groove (4) in the side of described first section bar (1) and the second section bar (2), opposite side is respectively equipped with ball-shaped fastener (5); Described ball-shaped groove (4) is mated mutually with ball-shaped fastener (5); Ball-shaped fastener (5) cover of the first section bar (1) is buckled in the ball-shaped groove (4) of Second-Type material (2); Ball-shaped fastener (5) cover of the second section bar (2) is buckled in the ball-shaped groove (4) of the first section bar (1); Ball-shaped groove (4) inwall mutually coincide with ball-shaped fastener (5) respectively and mutually against; And form cylinder slide rail, ease of assembly.
Advantage of the present utility model: 1, the utility model utilizes the surface of contact of Surface of Sphere large, weares and teares minimum, the minimum feature of resistance, as fastening, has efficiency when section bar is fastened high, quality surely, qualitative reliable superiority; 2, the utility model structure is simple, is skillfully constructed, and design science is reasonable, and it is extremely convenient to use, accurate positioning, and steadiness is strong, and have and install reliably, the advantage of interchangeability and highly versatile, its processing and fabricating is comparatively simple simultaneously, and cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Symbol description in figure: the first section bar 1, second section bar 2, connecting rod 3, ball-shaped groove 4, ball-shaped fastener 5.
Embodiment
By best embodiment, the utility model is described in detail below.
As shown in Figure 1, a kind of aluminium alloy extrusions circular arc fastener, is characterized in that being made up of the first section bar (1), the second section bar (2) and connecting rod (3); Described connecting rod (3) is snapped between the first section bar (1) and the second section bar (2) for " work " shape section bar respectively; Described first section bar (1) matches with the shape size of the second section bar (2); Be respectively equipped with a ball-shaped groove (4) in the side of described first section bar (1) and the second section bar (2), opposite side is respectively equipped with ball-shaped fastener (5); Described ball-shaped groove (4) is mated mutually with ball-shaped fastener (5); Ball-shaped fastener (5) cover of the first section bar (1) is buckled in the ball-shaped groove (4) of Second-Type material (2); Ball-shaped fastener (5) cover of the second section bar (2) is buckled in the ball-shaped groove (4) of the first section bar (1); Ball-shaped groove (4) inwall mutually coincide with ball-shaped fastener (5) respectively and mutually against; And form cylinder slide rail, ease of assembly.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
