Description
Technical Field
The utility model relates to a building materials field, in particular to stealthy connecting piece of aluminium alloy.
Background
The aluminium alloy is that an aluminium bar passes through the hot melt, the aluminium material of the different shapes that obtains after the extrusion, generally all can be equipped with the bar groove on the aluminium alloy, and set up the mounting hole on the bar groove, two aluminium alloy are connected to the aluminium alloy connecting piece of constituteing by two mutually perpendicular's connecting plates commonly used, so that two aluminium alloy mutually perpendicular are fixed, generally set up the mounting hole on the connecting plate, and pass the mounting hole on the aluminium alloy and the mounting hole on the connecting plate with the fastener, make aluminium alloy and connecting plate fixed. However, the connection method needs to open holes on the surface of the aluminum profile, and the material itself is damaged due to complex operation. And the leaky fastener is not aesthetically pleasing.
Disclosure of Invention
The utility model aims at shortcoming and problem that exist among the background art improve and the innovation, provide an invisible connection spare of aluminium alloy, including aluminium alloy and connecting piece, four angles of aluminium alloy respectively are equipped with a through-hole along its length direction, and the positive center of aluminium alloy is equipped with the connecting hole, the cross sectional shape of connecting piece is the same with the cross sectional shape of aluminium alloy, and four angles of the terminal surface of connecting piece are outwards respectively the protrusion have the inserted block, the shape and the size and each through-hole phase-match of inserted block.
In one embodiment, the inner wall of the connecting hole is provided with internal threads, the center of the end face of the connecting piece is provided with a round hole with the same aperture as the connecting hole, and the connecting piece and the aluminum section bar are fixed through a bolt connected between the round hole and the connecting hole.
In one embodiment, the surface of the connecting piece is provided with a groove communicated with the round hole along the axis.
In one embodiment, the surface of the groove is provided with a cover plate matched with the groove.
In one embodiment, the two sides of the groove are symmetrically provided with insertion holes, and the bottom surface of the cover plate is provided with insertion bolts matched with the insertion holes.
In one embodiment, the connector is L-shaped.
The utility model has the advantages that: the cross sectional shape of connecting piece is the same with the cross sectional shape of aluminium alloy to groove adopts the apron closed, so when adopting this connecting piece to carry out the connection of aluminium alloy, can close the connecting piece as an organic whole with the aluminium alloy that needs to be connected, reaches the effect of "stealthy", and the assembly is simple and convenient, and guaranteed pleasing to the eye.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It will be understood that when an element is referred to as being "disposed" or "connected" to another element, it can be directly disposed or connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description presented herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 1-4, the invisible connecting piece of the aluminum profile mainly comprises an aluminum profile 1, a connecting piece 2, a bolt 3 and a cover plate 4. Wherein: the aluminum profile 1 is an aluminum alloy profile with the model number of 8-4040L, four corners of the aluminum alloy profile are respectively provided with a through hole 11 along the length direction, and the center of the aluminum alloy profile is provided with a connecting hole 12.
The connecting piece 2 is right-angled L-shaped strip, the cross section of the connecting piece 2 is the same as that of the aluminum profile 1, four corners of the end face of the connecting piece 2 are outwards protruded with inserting blocks 21, and the shapes and the sizes of the inserting blocks 21 are matched with the through holes 11.
The inner wall of the connecting hole 12 is provided with internal threads, the center of the end face of the connecting piece 2 is provided with a round hole 22 with the same aperture as the connecting hole, the surface of the connecting piece 2 is provided with a groove 23 communicated with the round hole 22 along the axis, the bolt 3 is arranged in the groove 23, and then the round hole 22 is in threaded connection with the connecting hole 12, so that the connecting piece 2 is fastened with the aluminum profile 1.
The surface of the groove 23 is provided with a cover plate 4 matched with the groove 23, two sides of the groove 23 are symmetrically provided with insertion holes 24, and the bottom surface of the cover plate 4 is provided with insertion bolts 41 matched with the insertion holes 24.
The utility model discloses when using, at first insert the through-hole 11 of two sections aluminium alloy 1 that need connect respectively with the inserted block 21 at the both ends of connecting piece 2 in. Put into bolt 3 through recess 23, fix aluminium alloy 1 and connecting piece 2 through bolt 3, close recess 23 with apron 4 again.
Because the cross sectional shape of connecting piece is the same with the cross sectional shape of aluminium alloy to groove adopts the apron closed, so when adopting this connecting piece to carry out the connection of aluminium alloy, can close the connecting piece as an organic whole with the aluminium alloy that needs to be connected, reaches the effect of "stealthy", and the assembly is simple and convenient, and has guaranteed beautifully.
