Description
Technical Field
[0001] The utility model belongs to the technical field of fasteners, and in particular relates to a vibration-proof and loose-proof fastener. Background Art
[0002] Fasteners are a type of mechanical parts used for fastening connections and are extremely widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, and so on. Various fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters, and supplies. Fasteners are mainly used for fixing.
[0003] The fasteners currently available on the market have the following problems in actual use:
[0004] 1. When using traditional fasteners, the clamped objects are only clamped by the elasticity of the material. The clamping state is poor. When the clamped objects are turned over, the clamped objects may be separated from the fasteners, and the stability is poor during use.
[0005] 2. During the use of most fasteners, since the clamped objects need to be clamped and fixed, the clamped objects themselves are relatively fragile. When the fasteners clamp and fix the clamped objects, it may cause wear at the contact point between the clamped objects and the fasteners, causing damage to the clamped objects, and the protective performance is poor during use.

[0029] A card slot 14 is provided on the surface of the clamping block 2, and a card block 17 is clamped inside the card slot 14. The surface of the card block 17 is fixedly connected to a soft strip 13, and the soft strip 13 is located on the surface of the clamping block 2. The external threaded rod 7 is sleeved inside the clamping block 2, and the external threaded rod 7 passes through the card block 17. A nut 16 is installed on the surface of the external threaded rod 7, and one end of the nut 16 is fitted to the clamping block 2. By installing the soft strip 13, the soft strip 13 is used to replace the anti-vibration and anti-loosening fasteners and the contact making, which provides protection for the clamped object when in use, so that the clamped object will not be cleaned and worn, and has protective properties when in use.
