Embodiment
Shown in referring to Fig.1~Fig. 4, the utility model discloses a kind of aluminium section connecting pieces, and first including mutual split
Main body 10 and the second main body 11.
The bottom of above-mentioned first main body 10 and the second main body 11 is respectively set close to Mosaic face and along the direction of splicing seams
There is the fixture block 12 of " L " font of mirror image each other.After first main body 10 and the splicing of the second main body 11, two fixture blocks 12 piece together handstand
It is T-shaped, can be fastened in the half closed slot 52 of 50 side of aluminum profile, while half closed slot can keep 10 He of the first main body
The split of second main body 11 prevents its disengaging, improves the stability that aluminum profile 50 splices.
Screw hole 140 is disposed in above-mentioned first main body 10 and the second main body 11 from top to bottom, chamber 14 is screwed, is connected to
Chamber 141 and hole 142 is screwed, it is symmetrical with Mosaic face.Screw hole 140 is on the roof of the first main body 10 and the second main body 11
Through-hole, be connected to chamber 14 is screwed.Connection chamber 141 is connected to chamber 14 is screwed.Screwing hole 142 is positioned at the first main body 10 and the
Through-hole on the bottom wall of two main bodys 11 is connected to chamber 141 is connected to.
Bolt 30 is equipped in above-mentioned screw hole 140, the outer diameter of bolt 30 is identical with the internal diameter of screw hole 140, to keep
The direction of bolt, while blocking is provided to bolt head 31.The bolt head 31 of bolt 30, which is located at, to screw in chamber 14, and bolt 30 is in addition
One end is provided with expanding block 20, and expanding block 20 is located at the outside of the first main body 10 and the second main body 11.It is provided in expanding block 20
With the matched screw thread of bolt 30.The pushing surface 21 of 20 side of expanding block be in indent arc-shaped, the radius of circular arc from top to bottom by
It is cumulative big, so that the sectional area on 20 top of expanding block is consistently greater than the sectional area of lower part.It can be set on pushing surface 21 along bolt
The fool proof draw runner 22 in 30 directions.Nut bore 23 can be set at the top of expanding block 20.High-intensitive aluminum profile 50 is needed to connect
When, can in nut bore 23 fixture nut, increase bonding strength;When not needing high-intensitive connection, expansion can be only used
Screw thread and bolt 30 in block 20 cooperate, and to mitigate weight, improve property easy to use.
The top of above-mentioned first main body 10 and the second main body 11 is displayed centered on bolt 30 and is provided with expansion leaves 13.It is swollen
The number of swollen blade 13 is identical with the number of pushing surface 21.The inner surface of expansion leaves 13 is in the arc-shaped of evagination, and the half of circular arc
Diameter is gradually increased from top to bottom, the opening for the chamber for surrounding expansion leaves 13 is gradually reduced from top to bottom, and its topmost is opened
Mouth size is greater than the size of 20 bottommost of expanding block, and expanding block 20 is facilitated to be put into;The opening size of its mobilizable lowest part is small
In the size of 20 top of expanding block, expansion leaves 13 is enable to expand.It is opened on the wherein arc surface of an expansion leaves 13
Equipped with fool proof sliding slot 130, cooperate with fool proof draw runner 22, on the one hand can prevent expansion Block direction from misplacing, it on the other hand can also
To increase resistance when screwing, expanding block rotation is prevented.Expansion leaves 13 can be spliced face and be divided into that be located at first main
Two demiinflation blades on body 10 and the second main body 11 make the uniform force of the first main body 10 and the second main body 11, improve steady
It is qualitative.
Fool proof groove 161 and spacing block set 170 are provided on the Mosaic face of above-mentioned first main body 10.Fool proof groove 161 is inclined
Central axis from the first main body 10.Spacing block set 170 is symmetrical arranged with the central axis of the first main body 10.Above-mentioned second main body
Fool proof convex block 160 and limiting groove 171 are provided on 11 Mosaic face.Fool proof convex block 160 deviates the central axis of the second main body 10
Line is inserted into fool proof groove 161, and anisotropy when preventing the first main body 10 and the second 11 split of main body increases and uses
When reliability.Limiting groove 171 is symmetrical arranged with the central axis of the second main body 11, and spacing block set 170 is inserted into limiting
In groove 171, to prevent the first main body 10 and the second main body 11 from being mutually disengaged in the vertical direction, stability is improved.
Split fixation hole 15 is provided in above-mentioned first main body 10 and the second main body 11.Split fixation hole 15 is perpendicular to spelling
Junction, and deviate the central axis of the first main body 10 or the second main body 11.The split of first main body 10 and the second main body 11 is fixed
Hole 15 is interconnected, and when aluminum profile 50 needs high-intensitive connection, can be used for screw and fixes.
Loss of weight chamber 18 is offered in above-mentioned first main body 10 and the second main body 11, for mitigating weight.
The course of work:
Expanding block 20 is screwed in the end of thread of bolt 30;Chamber 14 is screwed by what bolt head 31 was placed on the first main body 10
Interior, bolt passes through screw hole 140, and expanding block 20 is made to be located at the free end of expansion leaves 13;Second main body 11 is spliced first
In main body 10;Expansion leaves 13 are inserted into the hole of aluminum profile 50, is passed through using screwing tool 40 and is screwed hole 142 and screw bolt 31
Head moves downward expanding block 20, to push the expansion of expansion leaves 13, is firmly stuck in the hollow hole 51 of aluminum profile 50;
Screwing tool 40 can be taken away after the completion of splicing, convenient and efficient, bolt 30 will not be because of unexpected loosening;By fixture block 12 from aluminium behind face
The end of profile 50 slides into half closed slot 52, that is, completes the splicing of two aluminum profiles 50 in different directions;It, will when needing to dismantle
Fixture block 12 skids off half closed slot, screws bolt head 31 using screwing tool 40, can remove.
