Abstract
The utility model relates to a plug bolt with two expanded ends to fix an object on a wall, pertaining to fastening piece technical field. Aiming at solving the problems that when screwing the nut, the part of the bolt out of the wall surface will become longer if being pulled, and the bolt on the plug bolt already screwed on the wall is difficult to dismantle on current traditional plug bolt with only one expanded end, the utility model provides a plug bolt with two expanded ends which is characterized in that when screwing the bolt, the part of the bolt out of the wall surface will not become longer if being pulled and the bolt on the plug bolt already screwed on the wall is easy to dismantle. The utility model comprises a bolt, a gasket, a cone plunger ring, an expanded sleeve and a cone threaded plunger ring. The key points of the utility model lie in that both ends of the expanded sleeve are provided with a plurality of notches; the gasket, the cone plunger ring, the expanded sleeve and the cone threaded plunger ring are hitched on the bolt in order; the cone plunger ring is moveably matched with the bolt and the cone threaded plunger ring is screwed with the bolt.
Description
Technical field
The utility model relates to technical field of fastening, particularly a kind of object is anchored on two expansion EXPANSION ANCHOR BOLTS on the wall.
Background technique
The existing EXPANSION ANCHOR BOLTS that object is anchored on the wall all is single head expansion EXPANSION ANCHOR BOLTS, they generally are made up of bolt, nut, pad and expansion sleeve, wherein the taper jacking block is made or be provided with to the tail end of bolt, the top diameter of taper jacking block is less than the internal diameter of expansion sleeve, the diameter at butt end of taper jacking block is greater than the external diameter of expansion sleeve, and expansion sleeve, pad, nut are enclosed within on the bolt successively.In the use, existing single head expansion EXPANSION ANCHOR BOLTS exists following defective: bolt exposes wall surface part and can draw longer and longer when screwing nut, and the degree of depth that bolt inserts in the wall studs hole can be drawn more shallow and more shallow, this makes the fastening force that object is anchored on the EXPANSION ANCHOR BOLTS on the wall reduce, the object that is fixed on the wall comes off easily, and after dismounting was fixed on object on the wall, the bolt on the EXPANSION ANCHOR BOLTS was difficult for being removed, still stay on the wall, this is not easy to the recovery of wall surface.
Summary of the invention
The utility model at existing single head expansion EXPANSION ANCHOR BOLTS in use exist screw nut the time bolt expose wall surface part and can draw longer and longer, can draw more and move more outward and insert bolt in the wall studs hole, make the object that is fixed on the wall insecure, take off the very difficult defective of bolt on the EXPANSION ANCHOR BOLTS of adorning on the wall, provide a kind of when screwing bolt bolt expose wall surface part and can not be elongated, the bolt that inserts in the wall studs hole can not move outward, the object that is fixed on the wall is not easy to come off, and the bolt that take off on the EXPANSION ANCHOR BOLTS of having adorned on the wall is easy to two expansion EXPANSION ANCHOR BOLTS.
The technical solution adopted in the utility model is finished in the following way: two expansion EXPANSION ANCHOR BOLTS comprises bolt, pad, taper trim ring, expansion sleeve and tapered thread trim ring.Wherein, the top diameter of taper trim ring is less than the internal diameter of expansion sleeve, and the diameter at butt end of taper trim ring is greater than the external diameter of expansion sleeve; The top diameter of tapered thread trim ring is less than the internal diameter of expansion sleeve, and the diameter at butt end of tapered thread trim ring is greater than the external diameter of expansion sleeve; Two ends at expansion sleeve respectively have some flutings; Pad, taper trim ring, expansion sleeve, tapered thread trim ring are enclosed within on the bolt successively, wherein, for movingly, are screw-thread fit between tapered thread trim ring and the bolt between taper trim ring and the bolt.In use, when screwing bolt, tapered thread trim ring outside top expansion sleeve and make inner expansion of expansion sleeve that itself and inner hole wall are killed under threaded function; Taper trim ring inside top expansion sleeve and expanded in the expansion sleeve outer end itself and inner hole wall to be killed, prevent to be drawn out under the pressure effect of pad and bolt head because of bolt when screwing bolt.When unscrewing bolt, because of being screw-thread fit between tapered thread trim ring and the bolt tail, so the bolt that will take off on the EXPANSION ANCHOR BOLTS of having adorned on the wall is easily.
The utility model two expansion EXPANSION ANCHOR BOLTS is compared with existing common single head expansion EXPANSION ANCHOR BOLTS, having when screwing bolt bolt exposes the wall surface part and can not be elongated, the bolt that inserts in the wall studs hole can not move outward, the power of fastening object is big, the object that is fixed on the wall is not easy to come off, the bolt that takes off on the EXPANSION ANCHOR BOLTS of adorning on the wall is easy to characteristics, and the utility model is particularly suitable as and a kind of object is anchored on EXPANSION ANCHOR BOLTS on the wall.
