Abstract

The utility model discloses a hollow bolt, which comprises a head and a screw, wherein a groove is axially formed in a central position at the bottom of the screw; and the screw is provided with a cylindrical through hole perpendicular to the axis of the groove. According to the hollow bolt, the problems of higher production cost and poor fastening effect in the prior art are solved; by arranging the screw of the bolt to be hollow, the production material is saved, and the weight of the bolt is also reduced; and meanwhile, the screw can be sleeved on a product to be connected on some specific occasions, so that the fixation effect is better.

Description

A kind of hollow bolt
Technical field
The utility model has related to a kind of hollow bolt, belongs to the connection technical field of fastening.
Background technique
At present, widely used bolt fastener generally is the solid body structure, but the whole weight of the bolt of solid body structure is relatively large, and cost of production is also relatively high, and at some specific occasion fixed effects and bad.
The model utility content
Technical problem to be solved in the utility model provides a kind of hollow bolt, by screw design is become hollow shape, has not only saved cost, and does not affect fastening effect, and it is relatively better to be fastenedly connected effect in some specific occasions.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of hollow bolt comprises head and screw rod, and described screw rod bottom centre position is provided with a groove vertically.
Aforesaid a kind of hollow bolt is characterized in that: described screw rod is provided with one perpendicular to the cylindrical hole of the axis of described groove.
Aforesaid a kind of hollow bolt is characterized in that: the bottom of described groove is for conical.
Aforesaid a kind of hollow bolt is characterized in that: described head is provided with a toroidal cavity.
The beneficial effects of the utility model are: by the screw rod of bolt is arranged to hollow shape, not only saved the production material, and alleviated the weight of bolt, simultaneously in some specific occasions, can with screw sleeve on product to be connected, make fixed effect better.
Description of drawings
Fig. 1 is the side view of a kind of hollow bolt of the utility model;
Fig. 2 is the plan view of a kind of hollow bolt of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As depicted in figs. 1 and 2, a kind of hollow bolt, comprise head 1 and screw rod 2, described screw rod 2 bottom centre positions are provided with a groove 3 vertically, thereby reduced the cost of production of product, described screw rod 2 is provided with one perpendicular to the cylindrical hole 4 of the axis of described groove 3, when utilizing bolt fixing, can also be by in the groove 3 shown in product to be connected is inserted into, and pass by 4 and product to be connected by links such as latches, realized the dual of product to be connected fixed, made fastening better effects if.The bottom of described groove 3 is conical, makes its supporting surface to product to be connected larger, fastening better effects if, and described head 1 is provided with a toroidal cavity 5.
In sum, a kind of hollow bolt that the utility model provides by screw design is become hollow shape, has not only been saved cost, and does not affect fastening effect, and it is relatively better to be fastenedly connected effect in some specific occasions.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
