Abstract
The utility model relates to a screw used in the hollow structure, comprising a screw, characterized in that one end of the screw is a cylinder of a screw thread, one flat and quadrate end is connected with an elbow through a movable axis, the elbow is in a shape like a Chinese character 'jiong', and the middle part of the upper plane is opened with a threading via hole with a quadrate tail end. The utility model becomes a right angle with the screw under the action of gravity through the movable elbow after threading into the hollow structure, and the elbow blocks the drilling hole of the hollow structure, which makes the screw unable to loose when fixedly and externally hanging the weight things. The utility model has simple structure, doesn't need to thread through the two walls of the hollow structure, and also doesn't affect the appearance of the hollow structure.
Description
Technical field
The utility model relates to a kind of screw, is specifically related to a kind of screw that is applied to hollow structure.
Background technique
Existing screw, swell fixture, screw comprise screw and bolt, and swell fixture comprises: a screw is formed by a standard package; One location sleeve, an end internal diameter tool internal thread, the outer tool outside thread of an end external diameter; One expansion sleeve, the one end has internal thread; One inserts the circular cone in the expansion sleeve the other end.Existing screw or swell fixture are when the body of wall of fixing isolation hollow or object, during its plug-in fixture, under the object action of gravity, screw or swell fixture can produce loosening, therefore, when they are applied in the body of wall of hollow or object, must penetrate hollow two walls, not attractive in appearance, do not penetrate then insecure.
The model utility content
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of screw that can be applicable to hollow structure.
To achieve these goals, the utility model adopts following technological scheme:
Be applied to the screw of hollow structure, it comprises screw, elbow, and an end of screw is the cylinder of screw thread, a flat rectangular end is by the axle Loose joint bend, elbow is a Jiong shape, strengthens stressedly, and the intermediate portion on plane has the through hole that a rectangular end passes thereon.
Elbow is divided into not reciprocity two sections by axle, and behind the insertion hollow structure, wherein long section hangs under action of gravity naturally at the inner lock state that forms of hollow structure, by the external nut cooperation screw is fastened on the hollow structure.
Above-mentioned screw is provided with nut.
Behind the hollow structure inside that penetrates, action of gravity meets at right angles with screw down the utility model again by movable elbow, and elbow blocks the boring of hollow structure, makes screw can not produce loosening when fixing plug-in weight.The utility model is simple in structure, does not need to penetrate hollow structure two walls, does not influence the outward appearance of hollow structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of elbow bending.
Embodiment
As shown in Figure 1, 2, be applied to the screw of hollow structure, it comprises screw 1, elbow 4, one end of screw 1 is the cylinder of screw thread, one end of flat rectangular 2 is by movable axis 3 connecting bends 4, and elbow 4 is a Jiong shape, and the intermediate portion on plane has the through hole that a rectangular 2 ends pass thereon; Screw in nut 5 and pad 6 on the screw 1.
Claims (3)
1, is applied to the screw of hollow structure, it comprises screw, it is characterized in that: an end of screw is the cylinder of screw thread, and a flat rectangular end is by the movable axis connecting bend, elbow is a Jiong shape, and the intermediate portion on plane has the through hole that a rectangular end passes thereon.
2, the screw that is applied to hollow structure according to claim 1 is characterized in that: elbow is divided into not reciprocity two sections by axle.
