Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 with figure 2 As shown, a hollow bolt includes a head 1 and a screw rod 2. A groove 3 is arranged in the center of the bottom of the screw rod 2 in the axial direction, thereby reducing the production cost of the product. The screw rod 2 is provided with a vertical The cylindrical through hole 4 on the axis of the groove 3, while being fixed by bolts, can also insert the product to be connected into the groove 3, and pass through the 4 and the The product to be connected realizes the double fixation of the product to be connected, so that the fastening effect is better. The bottom of the groove 3 is conical, so that the supporting surface of the product to be connected is larger and the fastening effect is better. The head 1 is provided with an annular groove 5 .

[0014] To sum up, the hollow bolt provided by the present invention not only ...

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 [0001] The invention relates to a hollow bolt and belongs to the technical field of connecting fasteners. Background technique [0002] At present, widely used bolt fasteners are generally of solid structure, but the overall weight of the bolt of solid structure is relatively large, the production cost is also relatively high, and the fixing effect is not good in some specific occasions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hollow bolt. By designing the screw rod into a hollow shape, not only the cost is saved, but also the fastening effect is not affected, and the fastening connection effect is relatively better in some specific occasions. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A hollow bolt includes a head and a screw rod, and a groove is arranged in the center of the bottom o...
