Abstract
A rotary fastener with herringbone comprises two fastener bases connected through a bolt pin and two covering plates connected with the fastener bases, wherein the two fastener bases can mutually rotate in any angles, one side of one fastener base is connected with one covering plate through a small bolt pin, and the other side of the fastener base is connected with the other side of the covering plate through a connecting bolt. Herringbone fine threads in an angle of 45 degrees are arranged in internal surfaces of the two covering plates and the two fastener bases, so that friction coefficients between fasteners and connected steel pipes are increased, and friction forces between the fasteners and the connected steel pipes are increased. Simultaneously, two circular arc grooves are arranged at the positions of the covering plates connected with the bolt, so that a sliding of gaskets and nuts of the connecting bolts can be restricted. According to the rotary fastener with herringbone, the structure is simple, the problem of poor skid resistance of the fasteners is solved, bearing capacity of the fasteners is improved, the outward sliding of the gaskets and the nuts of the connecting bolts is restricted, and the reliability of the fastener connection is improved.
Description
Technical field
The utility model relates to two steel pipes and is arbitrarily angled continuous revolution fastener technology field.
Background technology
At present, the inner surface of fastener type steel pipe scaffold revolution fastener is the light face generally not through handling.Because fastener type steel pipe scaffold is to lean on the frictional force between fastener and the steel pipe to transmit load, so the frictional force contacting piece formula steel pipe scaffold between fastener and the steel pipe is most important.Therefore, need a kind of anti-slide performance good, connect revolution fastener reliably.
Summary of the invention
In order to overcome the deficiency of existing revolution fastener anti-slide performance difference, the utility model provides a kind of revolution fastener, and this revolution fastener is bigger with the friction factor that is connected between steel pipe, and bigger frictional force can be provided, and anti-slide performance is good, connects reliable.
The technical scheme of the utility model is: two Button Blocks link to each other through pin, and can rotate each other and be arbitrarily angled, and Button Block one side links to each other with cover plate through little pin, and opposite side is provided with connecting bolt, is used for being connected with the opposite side of cover plate.Inner surface at two cover plates and Button Block is provided with 45 ° of herringbone microgrooves, increases fastener and the friction factor that is connected between steel pipe, increases fastener and the frictional force that is connected between steel pipe.Simultaneously, on the cover board the position of connecting bolt is provided with the groove of two circular arcs, and the pad and the nut that can limit connecting bolt slide, and guarantee the fastening effect of fastener.
The utility model is simple in structure, has increased fastener and the frictional force that is connected between steel pipe, has improved the problem of fastener skid resistance difference, and the pad and the nut of restriction connecting bolt outwards slide, and improve the reliability that fastener connects.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the front view of the utility model;
Fig. 2 is the constructional drawing of the utility model cover plate.
Among the figure: 1-Button Block, 2-cover plate, 3-pin, 4-connecting bolt, the little pin of 5-, 6-45 ° of herringbone microgroove, 7-circular groove.
The specific embodiment
Among Fig. 1, two Button Blocks 1 link to each other through pin 3, and can rotate each other and be arbitrarily angled, and a side of Button Block 1 links to each other with cover plate 2 through little pin 5, and opposite side is provided with connecting bolt 4, is used for linking to each other with the opposite side of cover plate 2.The inboard of Button Block 1 and cover plate 2 is provided with 45 ° herringbone microgroove 6.
Among Fig. 2; On the position of cover plate 2 connecting bolts, be provided with two circular grooves 7; The degree of depth of circular groove 7 is slightly larger than the thickness of connecting bolt 4 pads, during connection, the pad and the nut of connecting bolt 4 is put into circular groove 7; The pad and the nut of restriction connecting bolt slide, and improve the reliability that fastener connects.
