Abstract
The utility model discloses a two-way expansion bolt which comprises a bolt part or a screw as a fastener; tapered expansion plugs are arranged at the two ends of the bolt part or the screw; an axial through hole is formed in the tapered expansion plug at one end; the diameter of the through hole is larger than the diameter of a hexagonal bolt; an internal thread countersunk head is arranged on the tapered expansion plug at the other end; and an expansion jacket is arranged on the bolt part or the screw between the two tapered expansion plugs in a sleeving manner. The two-way expansion bolt is simple in structure, easy to manufacture and low in cost, and has four parts. The two-way expansion bolt is wide in application scope and high in adaptability, and can be applied to multiple fields of construction, machinery, processing and chemical engineering; compared with the traditional expansion bolts, the two sides or the external plane of the two-way expansion bolt keeps even after connection (with thicker workpieces); and the two-way expansion bolt is mainly applied to special occasions which require attractive appearances, such as a floor and a wall requiring evenness.
Description
Technical field
The utility model belongs to the component of machine technical field, relates in particular to a kind of EXPANSION ANCHOR BOLTS.
Background technique
EXPANSION ANCHOR BOLTS is mainly used on floor or the pedestrian aisle, when sheet material is connected with the floor, when using traditional EXPANSION ANCHOR BOLTS to connect, can leave nut at sheet material, protrudes on the ground, and the impact walking very easily damages the pedestrian.This just requires to be connected the height that rear fixing bolt is not higher or lower than the floor with ground at sheet material, could protect pedestrains safety.In the supreme society of the human rights nowadays, the design of human-based management, hommization is particularly important.
The model utility content
Problem to be solved in the utility model provides and can keep after a kind of connect two-sided smooth or outerplanar to keep smooth Bidirectional upset bolt.
In order to solve the problems of the technologies described above by the following technical solutions: a kind of Bidirectional upset bolt, comprise bolt or screw as fastening piece, bolt or screw two ends are respectively equipped with the tapered expansion plug; Wherein an end toper expansion plug is provided with axial through hole, and the aperture of through hole is greater than the diameter of interior six square bolts, and the other end tapered expansion is provided with the internal thread countersunk head beyond the Great Wall; Be arranged with the expansion overcoat on bolt between two tapered expansion plugs or the screw.
Described fastening piece is interior six square bolts, slotted screw or cruciform slot screw.
Described expansion overcoat is cylindrical shape, and its two ends are respectively equipped with four aperture lines radially.
Described expansion puts outward and is provided with hollow crumple texturing zone.
Described hollow crumple texturing zone is T shape, triangle or semicircle, and quantity is 2 ~ 8.
The utility model is simple in structure, making is easy, and is with low cost, totally four parts.The product applied range, strong adaptability can be used for building, a plurality of fields of machinery, processing, chemical industry.It is compared with the conventional expanded bolt, keeps two-sided smooth (thicker workpiece connects) or outerplanar to keep smooth after it connects.Be mainly used in requiring attractive in appearance or special occasions, require smooth occasion such as floor, wall etc.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of Bidirectional upset bolt comprises interior six square bolts 2 as fastening piece, and interior six square bolt two ends are respectively equipped with the tapered expansion plug; Wherein an end toper expansion plug 1 is provided with axial through hole, the aperture of through hole is greater than the diameter of interior six square bolts 2, the other end tapered expansion plug 4 is provided with the internal thread countersunk head, be arranged with on interior six square bolts between two tapered expansion plugs 3, two tapered expansion plugs of expansion overcoat respectively with expansion overcoat two ends close contact.During use, interior six square bolts 2 pass the tapered expansion plug 1 with through hole of an end, penetrate in the expansion overcoat 3 to be connected with the tapered expansion plug 4 with the internal thread countersunk head of the other end, thereby become one.The expansion overcoat is cylindrical shape, and its two ends are respectively equipped with four aperture lines radially, are convenient to it and freely open; Simultaneously, outer the putting of expanding is provided with hollow crumple texturing zone, be beneficial in use, though two workpiece connect, but still when having the slit, continues fastening in six square bolts, the expansion overcoat is out of shape, obtain the purpose that workpiece gap is reduced.
In use, can be used for the fastening of various storerooms, such as timber, steel, plastics etc.Install and use rear joint and be lower than workpiece surface or keep smooth with workpiece surface, the one, attractive in appearance, the 2nd, can satisfy the special occasions requirement, the place of projecting part should not be arranged such as floor or elbow place etc.
Above-described fastening piece can adopt the fluting of standard piece or non-standard or bolt or the screw of cruciform slot screw; Can also adopt bolt or the screw of other any styles, as using bolt or the screw of the special shapes such as square groove, triangular groove.
Hollow crumple texturing zone is T shape, triangle or semicircle, and quantity is 2,3,4,5,6,7 or 8.
Claims (5)
