Abstract
The utility model relates to the field of fasteners, in particular to a bolt with double hexagon bolt heads. The bolt comprises a bolt head, a screw rod and threads, wherein the screw rod is arranged on the bottom face of the bolt head in a downward-stretching mode, and the threads are formed on the outer edge of the screw rod. The bolt head is formed by welding the first hexagon bolt head and the second hexagon bolt head, the first hexagon bolt head and the screw rod are fixedly connected to the upper end face and the lower end face of the second hexagon bolt head respectively, the outer diameter of the first hexagon bolt head is smaller than that of the second hexagon bolt head, and an inner hexagon is cut on the upper end face of the first hexagon bolt head. The bolt head is formed by welding the first hexagon bolt head and the second hexagon bolt head which are different in outer diameter, the bolt with the double hexagon bolt heads is suitable for wrenches of two specifications when wrenched, and thus applicability is good. Meanwhile, after the inner hexagon is arranged in the bolt head, even though the outside hexagon bolt heads are deformed, the bolt can be quickly demounted by using the inner hexagon, and the service life of the bolt is prolonged.
Description
Technical field
The utility model relates to fastener areas, particularly a kind of pair of hex head bolt hook bolt.
Background technique
Bolt is by head and a screw rod class fastening piece dimerous, need coordinate with nut, for being fastenedly connected two with the part of through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connects, be to belong to removably connect.
Application number is that 201320017427.3 Chinese utility model patent discloses a kind of hex head bolt, comprises bolt head and screw rod, and the end face of described bolt head is arc shaped surface, and the screw rod of described bolt head is fixed with annular shell fragment on face.Although this hex head bolt can be by the distortion of annular shell fragment, make two to be connected and between part, to remain certain tension force, guarantee two connective stabilities that are connected between part, but the general only applicable a kind of specification spanner of outer-hexagonal size due to bolt head, when turning, can only adopt a kind of spanner of specification, poor for applicability.
Model utility content
The purpose of this utility model is to provide two hex head bolt hook bolts that a kind of energy suitable for various size spanner turns.
The utility model is that the technological scheme that its technical problem of solution adopts is,
A pair hex head bolt hook bolt, comprises bolt head, the screw rod extending to form from described bolt head bottom surface downwards and is formed at the screw thread in described screw rod outer rim; It is characterized in that: described bolt head is welded to form by the first hex head bolt head and the second hex head bolt head, the first hex head bolt head and screw rod are fixedly connected on respectively in the both ends of the surface up and down of described the second hex head bolt head, and the external diameter of the first hex head bolt head is less than the second hex head bolt head; On the upper-end surface of described the first hex head bolt head, be cut with an interior hexagonal; Screw rod at described the second hex head bolt head is fixed with annular shell fragment on face, and the center of described annular shell fragment is towards screw rod direction protuberance, and described screw rod runs through annular shell fragment; Described screw rod bottom surface is provided with a Hexagon boss, and the bottom surface of Hexagon boss is provided with screw-driver slot.
Further, described screw-driver slot inner concave shape is formed in described Hexagon boss bottom surface.
Further, described screw-driver slot is straight groove or cross recess.
Compared with prior art, the two hex head bolt hook bolts of the utility model have following advantage:
1, bolt head of the present utility model is welded by the first hex head bolt head and the second hex head bolt head of various outer diameter, when pulling, and the spanner of applicable two kinds of specifications, applicability is good.
2, the utility model is provided with after interior hexagonal in bolt head, even if the distortion of the hex head bolt head of outside still can utilize interior hexagonal to carry out quick-detachment bolt, has increased the working life of bolt.
3, the screw rod of bolt head described in the utility model is fixed with annular shell fragment on face, and swell towards screw rod direction at the center of described annular shell fragment.Therefore by this pair of hex head bolt hook bolt, by two, be connected part fixedly time, the annular elastomeric sector-meeting of the screw rod of its bolt head on face starts the side surface that contact is connected part, along with further tightening of this pair of hex head bolt hook bolt, annular shell fragment in above-mentioned will start distortion, thereby produce a rebounding force to being connected part, being finally two is connected between part and remains and guarantee two connective stabilities that are connected between part by certain tension force.
4, the utility model is by screw rod bottom surface, screw-driver slot being set, and in conjunction with original installing/dismounting portion---head, can realize multiple installation and removal mode simultaneously.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the two hex head bolt hook bolts of the utility model.
Fig. 2 is the plan structure schematic diagram of the two hex head bolt hook bolts of the utility model.
In figure: 1, bolt head, the 101, first hex head bolt head, the 102, second hex head bolt head, 2, screw rod, 3, screw thread, 4, annular shell fragment, 5, Hexagon boss, 6, interior hexagonal.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
Two hex head bolt hook bolts as shown in Figure 1 and Figure 2, comprise bolt head 1, the screw rod 2 extending to form from described bolt head 1 bottom surface downwards and are formed at the screw thread 3 in described screw rod 2 outer rims.
Described bolt head 1 is welded to form by the first hex head bolt head 101 and the second hex head bolt head 102, the first hex head bolt head 101 and screw rod 2 are fixedly connected on respectively in the both ends of the surface up and down of described the second hex head bolt head 102, and the external diameter of the first hex head bolt head 101 is less than the second hex head bolt head 102.Bolt head 1 of the present utility model is welded by the first hex head bolt head 101 and the second hex head bolt head 102 of various outer diameter, when pulling, and the spanner of applicable two kinds of specifications, applicability is good.
