Description
Technical field:
The utility model relates to interior six side's tack EXPANSION ANCHOR BOLTS that can play expansion that a kind of screw rod and cone are separated.
Background technique:
At present, the EXPANSION ANCHOR BOLTS of selling on the market, after fastening, the head of bolt all is exposed to the body of wall outside, relatively is easy to generate some bad consequences.For example: 1: in the middle of fastening process,,, unsuitable fastening than the phenomenon that is easier to cause that nut, screw rod rotate together because the cone of screw rod tail does not have guide function; 2: in the middle of the process of using,, the phenomenon of spanner usually can occur to use owing to the uncertainty in position, space; 3: not attractive in appearance.Pure white, smooth metope because the head of EXPANSION ANCHOR BOLTS protrudes out, can bring bigger contrast to visual effect; 4: dismounting is inconvenient.The part that comes out gets rusty easily, and after the time was permanent, dismounting was not got off; 5: cause danger easily.If the position of installing and using is lower, hangs bad clothing easily or cause inconvenience.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of tightness strong, elegant in appearance, easy for installation, safe and reliable interior six side's tack EXPANSION ANCHOR BOLTS.
The purpose of this utility model is achieved in that and comprises screw rod, the nut that matches with screw rod, is sleeved on the expansion sleeve on the screw rod, nut is installed in the afterbody of screw rod, nut be shaped as tapered cup nut, on the outer surface of tapered cup nut, be evenly distributed with guide structure, screw head is a hexahedron, has interior hexagonal hole on hexahedron.At screw head and treat to be provided with between the fixed block packing ring.
The utlity model has simple in structurely, easy to install, be widely used, advantage that can various occasions are used in indoor and outdoor.According to by the weight of loading product, select the tack EXPANSION ANCHOR BOLTS of suitable model for use.The tack EXPANSION ANCHOR BOLTS that model is bigger can be served as the ditch screw of stablizing lathe and be used.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that A of the present utility model is to schematic representation.
Fig. 3 is a tapered cup nut structural representation of the present utility model.
Embodiment:
As shown in Figure 1, 2, 3, the utility model comprises screw rod 1, the nut 5 that matches with screw rod 1, is sleeved on the expansion sleeve 4 on the screw rod 1, nut 5 is installed in the afterbody of screw rod 1, nut 5 be shaped as tapered cup nut, on the outer surface of tapered cup nut 5, be evenly distributed with guide structure, screw rod 1 head is a hexahedron, has interior hexagonal hole on hexahedron.At screw rod 1 head and treat to be provided with between the fixed block 3 packing ring 2.
Working principle of the present utility model is as follows: according to the diameter of selecting EXPANSION ANCHOR BOLTS for use, use electric impact drill, on wall, get bottom outlet, with interior six side's tack EXPANSION ANCHOR BOLTS, be inserted in the bottom outlet, use shfting wrench (or hexagon wrench), fine jade moves screw rod clockwise, tapered cup nut is outwards moved, and the expansion tube spreading plays fastening effect.
1, because the method that has adopted screw rod and cone to separate in the hexahedron of screw rod tail, increases interior hexagonal hole,, changes into and use allen wrench fastening so that should not use in the fastening space of spanner.2, screw rod and cone are separated,, increase by two guiding " ear ", overcome present EXPANSION ANCHOR BOLTS on the both sides of cone, in fastening process, the structural imperfection that nut, screw rod rotate together.3, owing to adopt screw rod not move, the method that cone moves, fastening after, exposed outside be a tack hexahedron, better appearance.4, when in use, a little butter or lead oil will be put in the cone, than being easier to dismounting.
