Abstract

The invention discloses a locking screw with an elastic element, which comprises a screw rod (1) provided with a vertical flute (3) and a bolt which is arranged in the flute (3), the locking screw is characterized in that the bolt is of an U-shaped structure which comprises a bolt head part (6) and a bolt tail part (5); a space (8) is formed in the bolt head part (6), and teeth (7) are arranged on the bolt tail part (5) and are meshed with screw threads of a nut (4) which is matched to the screw rod (1); and an elastic element is arranged at bottom of the U-shaped bolt. According to the locking screw, the locking screw is convenient to use and is capable of preventing the bolt from being clamped, can be inserted into or withdrawn easily without rotating the bolt.

Description

technical field [0001] The invention relates to a screw anti-loosening device, in particular to an anti-loosening screw with elastic parts. Background technique [0002] As a kind of fasteners in current production, screws are widely used in various industries. However, during use, the vibration of the equipment or the infiltration of external oil stains often cause the nuts of the screws and nuts to fall off, resulting in mechanical failure. Failure or even a major safety accident, people have thought of adopting various methods to prevent the screws from loosening. Now there are many kinds of anti-loosening screws on the market. For example, the thread on the screw is designed to be thinner, and the hole of the nut is made smaller to enhance the impact resistance of the screw. However, the production cost of the screw is relatively high. It is more laborious to use. [0003] Regarding the anti-loosening screws and methods, we retrieved the following public documents, for...
