Anti-loosening bolt for T-shaped nail

Abstract

The invention discloses an anti-loosening bolt for a T-shaped nail. The anti-loosening bolt comprises a bolt rod (1), a standard nut (2), an anti-loosening gasket (3) and a T-shaped nail (4), and is shown in a figure 1 described in the specification, wherein an inverted inner thread hole is drilled in the tip axle center of the standard bolt rod in the bolt rod (1), and is shown is the figure 1; the anti-loosening gasket (3) is a hexagonal gasket of which the inner circle diameter is slightly greater than the diameter of the bolt rod; one end of the gasket is provided with a square groove which is shown in a figure 3; the T-shaped nail (4) is shown in a figure 4; the size of a transverse rod of the T-shaped nail is matched with that of the square groove of the gasket (3); a screw rod of the T-shaped nail is matched with the inverted inner thread hole; after a component is tightened by using the standard nut (2), the transverse rod of the T-shaped nail (4) is inserted into the square groove of the anti-loosening gasket (3), and is reversely screwed into an inner thread hole of the bolt rod end till the transverse rod is screwed tightly; and if the nut (2) becomes loose, the T-shaped nail (4) is driven to rotate in the same direction, and the rotation direction is a direction in which the T-shaped nail (4) is screwed, so that the nut (2) is prevented from becoming loose, and the aim of preventing the bolt from becoming loose is fulfilled.

Description

[technical field] [0001] The invention relates to a bolt, especially an anti-loosening bolt. [Background technique] [0002] Most of the existing standard bolts use double nuts to prevent loosening. Although this method can achieve a certain anti-loosening effect, because the two nuts rotate in the same direction, they sometimes rotate at the same time, which cannot ensure the anti-loosening effect. the goal of. [Content of the invention] [0003] The object of the present invention is to provide an anti-loosening bolt that ensures the anti-loosening effect. [0004] In order to achieve the above object, the T-shaped nail anti-loosening bolt of the present invention consists of a bolt rod 1, a standard nut 2, an anti-loosening washer 3, and a T-shaped nail 4. See figure 1 . Bolt 1 is to drill a reverse internal threaded hole at the axis of the standard bolt end, see figure 1 ; Anti-loosening washer 3 is a washer with an inner circle diameter slightly larger than the di...
