Abstract
The utility model discloses an expansion bolt. The expansion bolt comprises a screw rod 1, an expansion sleeve 2 and a screw cap 3, wherein conicity is arranged in an inner hole of the expansion sleeve 2, the hole diameter of the front end of the expansion sleeve 2 is large, and the hole diameter is smaller inwards. Expansion bolts of the structure can not be loosed easily and are more tight upwards, and can be better fixed in holes which are needed to be fixed.
Description
The utility model relates to a kind of building or engineering connection fastening piece, specifically, is a kind of EXPANSION ANCHOR BOLTS.
The EXPANSION ANCHOR BOLTS of using generally comprises screw rod, nut and expansion sleeve at present, during use, by screwing in screw rod with expansion sleeve front end distending, makes bolt card in the hole of wall.The expansion sleeve aperture of traditional expansion bolt is fixed, after screw head entered expansion sleeve inside, the degree that expansion sleeve expands outwardly can be more and more littler, if the aperture of wall is bigger, will block the situation of not tight or bolt falling, in practice, often run into such phenomenon.
The purpose of this utility model be to provide a kind of overcome above-mentioned shortcoming, bolt can go up more tight more, can better be fixed on the EXPANSION ANCHOR BOLTS in the hole.
The utility model is achieved in that a kind of EXPANSION ANCHOR BOLTS, comprises screw rod, expansion sleeve and nut, and this expansion sleeve endoporus has tapering, and expansion sleeve front end aperture is big, and is more little to internal orifice dimension more.
The utility model has the advantages that: expansion sleeve has tapering, when screw head screws in expansion sleeve inside, because the expansion sleeve aperture is more and more littler, so the degree of expansion sleeve distending can be increasing, bolt can be gone up tight more more, needs in the fixing hole thereby can be good at being fixed on.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model sectional view.
Fig. 2 is the A-A sectional drawing of Fig. 1.
As shown in the figure, EXPANSION ANCHOR BOLTS comprises screw rod 1, expansion sleeve 2 and nut 3, and expansion sleeve 2 is enclosed within on the screw rod 1, and nut 3 is worn on the screw rod 1, and the endoporus of expansion sleeve 2 has tapering, and its front end is big, and is inwardly more and more littler.For preventing that screw rod 1 rotates in the process of bolting on, screw rod 1 afterbody is provided with two two parallel tangent planes 4, is used for fixing screw rod 1 as the spanner space.
It is tight more that the tapered configuration of expansion sleeve 2 can make bolt go up more, solved the loosening easily shortcoming of conventional expanded bolt, has good practical value.
Claims (2)
1, a kind of EXPANSION ANCHOR BOLTS comprises screw rod (1), expansion sleeve (2) and nut (3), it is characterized in that: this expansion sleeve (2) endoporus has tapering, and expansion sleeve (2) front end aperture is big, and is more little to internal orifice dimension more.
2, EXPANSION ANCHOR BOLTS according to claim 1 is characterized in that: this screw rod (1) afterbody has two parallel tangent planes (4).
