Abstract
The invention discloses a hollow bolt, which comprises a head part and a screw rod, wherein a groove is formed in the center at the bottom of the screw rod along the axial direction; and a cylindrical through hole which is vertical to the axes of the groove is formed on the screw rod. According to the hollow bolt, high production cost and poor fastening effect in the prior art can be solved, the screw rod of the bolt is arranged to be hollow, so that the production material can be saved, the weight of the bolt can be reduced, the screw rod can be sleeved on the product to be connected in specific situations, and the fixing effect is better.
Description
Technical field
The present invention relates to a kind of hollow bolt, belonged to the connection technical field of fastening.
Background technique
At present, widely used bolt fastener generally all 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 higher relatively, and at some specific occasions fixed effects and bad.
Summary of the invention
Technical problem to be solved by this invention provides a kind of hollow bolt, through screw design is become hollow shape, has not only practiced thrift cost, and does not influence fastening effect, and it is better relatively 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 present invention adopted is:
A kind of hollow bolt comprises head and screw rod, and said screw rod bottom centre position is provided with a groove vertically.
Aforesaid a kind of hollow bolt is characterized in that: said screw rod is provided with a cylindrical hole perpendicular to the axis of said groove.
Aforesaid a kind of hollow bolt is characterized in that: the bottom of said groove is for conical.
Aforesaid a kind of hollow bolt is characterized in that: said head is provided with a toroidal cavity.
The invention has the beneficial effects as follows: through the screw rod of bolt is arranged to hollow shape, not only practiced thrift the production material, and alleviated the weight of bolt,, can screw rod be enclosed within on the product to be connected, made fixed effect better simultaneously in some specific occasions.
Description of drawings
Fig. 1 is the side view of a kind of hollow bolt of the present invention;
Fig. 2 is the plan view of a kind of hollow bolt of the present invention.
Embodiment
To combine Figure of description below, the present invention will be further described.
As depicted in figs. 1 and 2, a kind of hollow bolt comprises head 1 and screw rod 2; Said screw rod 2 bottom centre positions are provided with a groove 3 vertically; Thereby reduced production cost of products, said screw rod 2 is provided with a cylindrical hole 4 perpendicular to the axis of said groove 3, when utilizing bolt; Can also be through in the groove 3 shown in product to be connected is inserted into; And pass through 4 and product to be connected through links such as latches, realized double fixed to product to be connected, make fastening better effects if.The bottom of said groove 3 is conical, makes its supporting surface to product to be connected bigger, fastening better effects if, and said head 1 is provided with a toroidal cavity 5.
In sum, a kind of hollow bolt provided by the invention through screw design is become hollow shape, has not only been practiced thrift cost, and does not influence fastening effect, and it is better relatively to be fastenedly connected effect in some specific occasions.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof.
