Abstract
The utility model discloses an expanding bolt component, which overcomes the problem of the skewness of the suspender caused by the drilling deflection of a basic hole. The utility model is characterized in a simple structure and a convenient application. The structure is that an expanding bolt component comprises an expanding sleeve, a bolt body and the matching nut. The characteristic of the utility model is that the bolt body is different diameter eccentric cylinder.
Description
Technical field
The utility model relates to a kind of expansion bolt assembly.
Background technique
At present, setscrew commonly used generally is by bolt, expansion sleeve, and nuts and washers is formed.During use, need put into the expansion sleeve of strap bolt behind the hole of getting certain depth and diameter on the building, fastening nut, the bolt of band tapering cap can the dilating expansion covers, and setscrew is fixed on the building firmly.Adopt the bolt of said structure, when the wall epidermis of building is hard material such as ceramic tile, the inclined to one side phenomenon of basic hole drill often occurs, its result will cause the deflection of hanger.
Summary of the invention
The utility model is exactly in order to address the above problem, provide a kind of have simple in structure, easy to use, the off-centre that can adjust the hanger position bolt assembly that expands.
To achieve these goals, the utility model has adopted following technological scheme: a kind of expansion bolt assembly, and it has expansion sleeve, and the body of bolt reaches nut engaged with it, and it is characterized in that: the described body of bolt is the reducing eccentric cylinder.
Packing ring and spring washer are arranged between described nut and expansion sleeve, dilatation joint is arranged on expansion sleeve.
Described expansion is sewed with three, is evenly distributed on the same circumferential surface, and wherein one length is identical with the length of expansion sleeve, and every dilatation joint all has a circular hole to communicate with it.
There is tapered cap the bottom of the described body of bolt.
In the utility model, the body of bolt is designed to the reducing eccentric cylinder, after expansion sleeve is opened fully, the eccentric part of the body of bolt is exposed outside, even if basic when mounted hole deflection also can be exposed outside eccentric part by adjusting, effectively prevent the deflection of hanger, also has advantage simple in structure, easy to use simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model expansion sleeve.
Embodiment
Among Fig. 1, the bottom of bolt volume 2 is a tapered cap 7, and the top is threaded, and the remaining part of screwed part and the body of bolt 2 is reducing, thereby makes the body of bolt 2 become the reducing eccentric cylinder.Nut 3 is sleeved on the top of the body of bolt 2, at nut 3 and 1 of expansion sleeve packing ring 4 and spring washer 5 is arranged.
Among Fig. 2, dilatation joint 6 is arranged on the expansion sleeve 1, totally three of dilatation joints 6 are on average arranged along the circumferential surface of expansion sleeve 1, and wherein one length is identical with expansion sleeve 1 length.Every dilatation joint 6 all has a hole to communicate with it.
