Abstract
The utility model discloses an expansion screw bolt. The utility model is composed of a standard screw bolt, a spring washer, a flat washer, an open sleeve tube and a conic screw nut. The utility model has the advantages that the metal materials are saved, the work efficiency is improved and the fastened articles have beautiful external appearance.
Description
The utility model relates to a kind of expand tube bolt, and particularly a kind of back of using is in the building surface EXPANSION ANCHOR BOLTS of Rose's head not.
At present, the EXPANSION ANCHOR BOLTS of selling on the market is the bolt that is had the tapering crown by head, expand tube with seam, standardized washer are formed with spring ring and standard nut, its using method is according to the weight of installation material or stressed size, select different screw specifications for use, and the hole of on building, getting the respective diameters and the degree of depth, put into the bolt and expand tube of setscrew afterwards after, put fastener again well, need only fastening nut then fastener can be securely fixed on the building.The application of last setscrew is very widely, but owing to consideration from the commodity practical standpoint, the bolt of its band tapering crown generally is long partially, use building outer meeting more or less in back to produce the silk head of staying the outside, this unnecessary bolt head is not promptly attractive in appearance also to be tended to hang the people and hangs thing and be prone to accidents.Sometimes because of need of work, must amputate working efficiency is reduced greatly exposing long screw.
The purpose of this utility model is to provide a kind of conical nut type EXPANSION ANCHOR BOLTS, be that original bolts and nuts are inverted use, make the expansion tapering crown that rises on original bolt become band tapering nut, so both solved the problem that the bolt head exposes, also reached practical and effect attractive in appearance.
The technical solution of the utility model, a kind of EXPANSION ANCHOR BOLTS is the nut by the band tapering.Expand tube with seam, packing ring and bolt are formed, the nut body of said band tapering is a frustum shape, there is tapped hole the center, said its length of expand tube with seam is 80～95% of bolt length, after the nut of band tapering inserts expand tube, bolt is joined by packing ring and nut, screw to reach and make the expand tube distending and bring into play it and fix by the effect of firmware on building, can also design fin on the awl mother can coincide with the expand tube seam, reaches to prevent to bore female effect of rotating.
Using method of the present utility model, common EXPANSION ANCHOR BOLTS is the same with using, and punches on building in advance, puts into the expand tube of having put tapered cup nut, and the aligning material installed is then tightened with corresponding bolt sleeve upper gasket and is got final product.(because of the fin effect, awl is female can not to be rotated by the seam of expand tube chucking) awl mother prolongs axial displacement when bolt rotates, owing to tapering must make radially distending of expand tube, till firmly.After installing, outer wall only exposes nuts, and is smooth and attractive in appearance.
Superiority of the present utility model: 1, solved original EXPANSION ANCHOR BOLTS outer wall Rose and the not beautiful problem of outward appearance; 2, can select the bolt kind as required arbitrarily, as all can with six sides, first cap or sunk screw; 3, cost is not high, is convenient to produce and can save a small amount of steel.
Further specify present technique below in conjunction with drawings and Examples.
Accompanying drawing 1 is a structural representation of the present utility model.
Wherein: 1 is the taper type nut; 2 is expand tube; 3 is plain washer; 4 is spring washer; 5 is bolt.
Embodiment: a kind of EXPANSION ANCHOR BOLTS is by cone table shape, and middle nut 1 with threaded hole, expand tube 2, plain washer 3, spring washer 4, bolt 5 with seam are formed, and after nut 1 is inserted expand tube 2, bolt 5 is joined by fastener and packing ring 3,4 and nut 1.Screw and to reach expand tube 2 distendings and bring into play its fixedly effect of fastener.
