A kind of adjustable fastener for installingTechnical field
The invention belongs to installing area, be specifically related to a kind of adjustable fastener for installing.
Background technique
Engineering or mechanical erection, often need to use fastener, the fastener of custom-shaped is had for steel pipe electric wire and so on, but shape is of little use or erection unit is larger time, just need customization in addition, when customized number is few, cost will be very high, and fastener Environmental Conditions is very easy to the phenomenon occurring oxide etch, maintenance difficult after damaging, not easily buys replacement part in time.
Summary of the invention
For solving the problem, the invention discloses a kind of adjustable fastener for installing, to need customization, flimsy problem with solving.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of adjustable fastener for installing, comprise fixed end, fastener body, folded end, described fixed end is positioned at the left end of fastener body, for cuboid, the upper and lower two ends of fixed end are symmetrical arranged fixed hole, angle between described fastener body and fixed end is 20 ° ~ 90 °, above fastener body, interval arranges bumping square and triangular bump, described folded end is positioned on the right side of fastener body, cross section is isosceles trapezoid, the folded end one end that connects with fastener body is greater than the other end, the upper and lower both sides of folded end arrange limit friction block, described limit friction block is triangle, base is overlapping with folded end, right edge is longer than limit, left side.
As a modification of the present invention, described fixed hole is at least 2.
As a modification of the present invention, the distance between described bumping square and triangular bump is no less than the base of triangular bump.
As a modification of the present invention, described folded section can use the Placements such as welding or riveted joint to fix.
As a modification of the present invention, described bumping square and triangular bump contour.
As a modification of the present invention, described novel fastener for installing is two-layer altogether, and inside arranges polymer composite elasitic layer, outer installment anticorrosive coat.
The invention has the beneficial effects as follows:
The adjustable fastener for installing of one of the present invention, one end arranges fixed end, fixed hole can be utilized first to fix, bumping square and triangular bump are set, frictional force can be increased, fix better and machinery is installed, and two kinds of different shapes can facilitate fastener body to be bent into different angles, distance between projection is no less than the length of triangle base, avoids mutual extruding, and two kinds of bump height are identical, to avoid wherein a kind of projection too high, make another lose effect, elasitic layer and anticorrosive coat are set in addition, increase the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numerals list:
1. fixed end, 2. fastener body, 3. folded end, 4. fixed hole, 5. elasitic layer, 6. anticorrosive coat, 7. bumping square, 8. triangular bump, 9. limit friction block.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, following embodiment should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
As shown in the figure, a kind of adjustable fastener for installing, comprise fixed end 1, fastener body 2, folded end 3, described fixed end 1 is positioned at the left end of fastener body 2, for cuboid, fixed end 1 is arranged fixed hole 4, the various angle folding fastener of person easy to use, with adapt to installation machinery shape, fixed end 1 utilizes fixed hole 4 first to fix, angle between described fastener body 2 and fixed end 1 is 20 ° ~ 90 °, in fastener body 2, interval arranges bumping square 7 and triangular bump 8, frictional force can be increased, fix better and machinery is installed, and two kinds of different shapes can facilitate fastener body 2 to be bent into different angles, described folded end 3 is positioned on the right side of fastener body 2, cross section is isosceles trapezoid, folded end 3 one end that connects with fastener body 2 is greater than the other end, folded end 3 utilizes the mode such as bolt or welding to fix after can folding, also can directly wipe out, or be folded to fixed end 1 time after the article that will be fixed tighten up, fix together with fixed end 1, folded end about 3 both sides arrange limit friction block 9, described limit friction block 9 is triangle, base is overlapping with folded end 3, right edge is longer than limit, left side, friction can be strengthened, and it is loose to make fastener not easily slide, can extend working time.
As shown in the figure, described fixed hole 4 is at least 2, can according to the size free adjustment of solid mechanical.
As shown in the figure, the distance between described bumping square 7 and triangular bump 8 is no less than the base of triangular bump 8, can adapt to various bending angle, can not produce between bumping square 7 and triangular bump 8 and mutually extrude, and fastening cannot install mechanical problem.
As shown in the figure, described folded section 3 can use the Placements such as welding or riveted joint to fix.
As shown in the figure, described bumping square 7 is contour with triangular bump 8, to avoid wherein a kind of projection too high, makes another lose effect.
As shown in the figure, described novel fastener for installing is two-layer altogether, and inside arranges elasitic layer 5, outer installment anticorrosive coat 6, and elasitic layer 5 is generally elastic metallic, and anticorrosive coat 6 is mainly moistureproof anti-oxidation, also can arrange anticorrosive coat 6 according to different situations.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned mode of execution, also comprises the technological scheme be made up of above technical characteristics combination in any.
