It is set respectively close to Mosaic face and along the direction of splicing seams on the side of above-mentioned first main body, 10 and second main body 11
It is equipped with the shallow slot 19 of mirror image each other.
Above-mentioned fixed cell includes the first rotary shaft 60 and the mounting hole that are separately positioned on the side wall of two shallow slots 19
600, the first rotary shaft 60 is inserted into the first mounting hole 600, on the one hand realizes the fixation of the first rotary shaft 60, on the other hand
It being capable of ease of assembly and fractionation.Positive stop lug boss 601 is provided in shallow slot 19.Shallow slot 19 can accommodate fixed cell completely, prevent
Misread lock.
Button 61 is provided in above-mentioned first rotary shaft 60, button 61 can rotate freely in the first rotary shaft 60,
Plane of rotation is parallel with Mosaic face.610 and second rotary shaft 62 of Button Handle is provided on button 61.
Above-mentioned Button Handle 610 is located at the free end of button 61, is in arc-shaped.Button Handle 610 is on the direction far from button 61
It is gradually thinning so that the free end of Button Handle 610 is detached from the bottom wall of shallow slot 19, and convenient hold moves.
Above-mentioned second rotary shaft 62 is located between 610 and first rotary shaft 60 of Button Handle, and length is less than the width of shallow slot 19,
And more than the width of button 61.
Bridgeware 63 is provided in above-mentioned second rotary shaft 62, bridgeware 63 is connected across the second rotary shaft 62 and exposes button 61
Both ends on.Bridgeware 63 can rotate freely in the second rotary shaft 62, and Plane of rotation is parallel with Mosaic face.
The bottom of above-mentioned bridgeware 63 is provided with extension stem 64 along the direction for being parallel to button 61, and the width of extension stem 64 is small
In the opening width of half closed slot 52.Extension stem 64 can be extend into from the opening of half closed slot 52 in half closed slot 52.
The free end of above-mentioned extension stem 64 is provided with snap finger 65.Snap finger 65 is strip plate, and length is more than half closed slot 52
Opening width.The plate face of snap finger 65 extends perpendicular to extension stem 64, and towards the direction of 19 bottom wall of shallow slot.The upper plate of snap finger 65
The distance of face to the central axis of the second rotary shaft 62 is slightly less than the inner top surface of half closed slot 52 to the central shaft of the second rotary shaft 62
The distance of line makes the second rotary shaft 62 form the barrier of power at peak, when the second rotary shaft 62 was broken peak manually
Afterwards, the second rotary shaft 62 can not oneself across barrier, so as to form stable fastening.After fastening, positive stop lug boss 601 can push
On extension stem 64, make the plate face of snap finger 65 and the inner top surface keeping parallelism of half closed slot 52, so as to the beginning to the second rotary shaft 62
Apply the power of the board direction perpendicular to snap finger 65 eventually, and the bottom wall of shallow slot 19 can push button 61 and form barrier, so as to make
Snap finger 65 keeps stable buckling state.
Above-mentioned lid closes unit and includes cover 70.The thin plate consistent with the cross sectional shape of aluminium section bar 50 for shape of cover 70.Lid
Body 70 can be integrally formed with connection unit or detach, to facilitate selective use.The side of cover 70
On open up jagged 71.The shape of notch 71 is consistent with the cross sectional shape of half closed slot 52, and at half closed slot 52.In cover 70
The inflation port 72 being provided through.Inflation port 72 is located at the extending bore 510 of 50 hollow hole 51 of aluminium section bar, quantity and extending bore
510 quantity is identical, to ensure stress balance.It is symmetrically arranged with centered on each inflation port 72 on the inner surface of cover 70 swollen
Expansion block 73, opposite two faces are mutually parallel.The internal diameter for being smaller than inflation port 72 between two expanding blocks 73, so as to
It is enough that expansion is realized after driving screws.The free end of expanding block 73 can carry out small swing.The free end of expanding block 73 is set
It is equipped with guide pad 74.The end face of 73 free end of guide pad 74 and expanding block seamlessly transits, one of side of guide pad 74 and
One of face in two symmetrical opposite faces of expanding block 73 at same inflation port 72 is coplanar, the other three of guide pad 74
Side is gradually collapsed in the direction far from expanding block 73, and side is made to form guide surface 740.Guide surface 740 can when mounted by
Expanding block 73 is imported in extending bore 510, facilitates installation.Two guide pads 74 at same inflation port 72 mirror image each other so that same
The opposite face keeping parallelism of two expanding blocks 73 and two guide pads 74 at one inflation port 72, can be longer so as to reach
It is expanded in length and with the purpose that phase same rate expands, improves the obturation effect after lid closes.
The course of work：
Connection：Expanding block 20 is screwed in the end of thread of bolt 30；Bolt head 31 is placed on screwing for the first main body 10
In chamber 14, 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
In first main body 10；Expansion leaves 13 are inserted into the hole of aluminium section bar 50, are passed through using screwing tool 40 and screw hole 142 and screw spiral shell
31, bolt, moves downward expanding block 20, is expanded so as to push expansion leaves 13, is firmly stuck in the hollow hole 51 of aluminium section bar 50
It is interior；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 behind face
It is slipped into half closed slot 52 from the end of aluminium section bar 50, that is, completes the splicing of two aluminium section bars 50 in different directions；It needs to dismantle
When, fixture block 12 is skidded off into half closed slot, screws bolt head 31 using screwing tool 40, you can remove.
It is fixed：After the completion of two aluminium section bars 50 splice, the Button Handle 610 that will be far from shallow slot 19 is broken to shallow slot 19, while will button
Pawl 65 is placed in half closed slot 52；Continue to move Button Handle 610, making the second rotary shaft 62, final button 61 is against shallow across peak
On the bottom wall of slot 19, and the upper face of snap finger 65 being attached on the inner top surface of half closed slot 52 tightly, form stable fastening；If
It needs to detach, then need to only break Button Handle 610 into two with one's hands manually.
Gai He：Expanding block 73 is inserted into extending bore 510；Using the identical screw of 72 internal diameter of outer diameter inflation port from cover 70
The expanded hole 72 in outer surface be screwable between two symmetrical expanding blocks 73；Because the outer diameter of screw is symmetrical more than two swollen
Spacing between expansion block 73, screw can be to both sides dilating expansion blocks 73, so as to which 73 side of expanding block be allowed closely to be fitted in extension
On two opposite inner walls of hole 510, the fixation of cover 70 is realized；When needing dismounting, screw is back-outed, cover 70 can be removed.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use the present invention.
A variety of modifications of these embodiments will be apparent for those skilled in the art, it is as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to consistent with principles disclosed herein and novel point
Most wide range.
