Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of large scale expansion bolt.
Background technology
Expansion bolt, be pipeline is propped up/hangs/bracket or equipment is fixing on the wall, on floor, a kind of special thread connector used on post.During use, first must get out the hole of corresponding size with electric impact drill (hammer) on fixed body, then in bolt, tube expansion load hole, tightening nut can make swelling between bolt, tube expansion, installed part and fixed body be integrally forming.
After tightening dilatable, bolt tail has a major part, one pipe more slightly larger than diameter of bolt of the outer surface cover of bolt, afterbody part You Ji road opening, after bolt is tightened, the afterbody of major part is just brought to inside the pipe of opening, big for pipe punching, reach the purpose expanded, and then being bolted on ground or wall, reach the purpose taken root.
But, its size of existing expansion bolt is all smaller, when fixing for large-sized object, it is easy to the scheme expected is to adopt more expansion bolt.Because its intensity of large-scale expansion bolt is not high, cause that its connective stability is not high.
Chinese patent its publication number CN203868069U discloses a kind of expansion bolt, including: dormant bolt, tube expansion, packing ring and nut composition, the sidewall of tube expansion offers the first and second grooves along the axis direction of tube expansion, first groove and the alternate layout of the second groove, the opening of the first groove is positioned at the tube expansion opening near nut, and the opening of the second groove is positioned at the tube expansion opening away from nut.Can be seen that from technique scheme, expansion bolt provided by the invention, the opening direction of the first groove and the second groove is contrary, and the tube expansion between the first groove and the second groove is all inflatable, expansion bolt relative to single direction fluting, it is possible to expand the dilation dimension of expansion bolt.
Can be seen that, in use, during to the direction fastening nut tightened, the dilation dimension of expansion bolt becomes big, to opposite direction unscrew nut time, the dilation dimension of expansion bolt diminishes, it is achieved that the adjustment of expansion bolt dilation dimension, increase the scope of application of expansion bolt, improve the versatility that expansion bolt uses.
But, when connecting for large and heavy objects, it is high or must adopt the problem by expansion bolt that quantity is relatively many that it does not still also exist intensity.
Summary of the invention
It is an object of the invention to the problems referred to above existed for prior art, it is provided that a kind of large scale expansion bolt.
The purpose of the present invention can be realized by following technical proposal:
A kind of large scale expansion bolt, including the body of rod and sleeve pipe, it is characterized in that, described body of rod the inner has the nut being connected as a single entity with it, described body of rod outer end is dismountable is connected to plush copper, above-mentioned casing pipe sleeve on the body of rod and sleeve pipe be limited between nut and plush copper, described outside of sleeve has the through hole run through, above-mentioned sleeve pipe has the breach being extended to through hole by its outer end, above-mentioned through hole and breach form a bulge and have some bulges on sleeve pipe, an expanding petal in flap is formed between above-mentioned adjacent two breach, described expanding petal has ruggedized construction, there is outside described plush copper the contact site that can increase frictional force.
Owing to this expansion bolt has ruggedized construction, therefore, expanding petal place has enough intensity.
This expansion bolt inserts after body of wall, is formed with body of wall by the contact site in plush copper and stable contact and have enough frictional force between plush copper and body of wall.
Now, applying external force rotating screw cap, owing to plush copper is fixed, therefore, sleeve pipe is subject to the extruding of plush copper, so that the expanding petal on sleeve pipe is to strutting outside it, the expanding petal after strutting is it is thus possible to formed with body of wall and be stably connected with.
In above-mentioned large scale expansion bolt, described through hole be strip and through hole axially arranged along sleeve pipe.
