Embodiment 1

[0017] like figure 1 As shown, a special anti-skid bolt of the present invention includes a bolt head 1 and a screw rod 2. The front end of the screw rod 2 is a threaded section, and the end close to the bolt head 1 is a smooth section. An oil injection groove 3 is provided, and the opening of the oil injection groove 3 is located at the bolt head 1. The smooth section is provided with an oil outlet channel 4 communicating with the oil injection groove. The solid cap 5 is tapered and protrudes to the outside of the screw rod, and the lower end of the fastening cap 5 is provided with a "wavy line"-shaped anti-slip tooth 6, and a bolt cap 9 with deformability is provided above the bolt head 1 Covered on the bolt head 1, the antirust oil storage chamber 7 is arranged in the bolt cap 9, and the antirust oil is stored therein.

[0018] Preferably, as the second embodiment of the present invention, this embodiment is a further limitation of the first embodiment, the anti-rust oil c...

Abstract

The invention relates to a multifunctional bolt and belongs to fasteners. According to the technical scheme adopted by the invention, the special anti-skid bolt comprises a bolt head and a threaded rod; a threaded section is arranged at the front end of the threaded rod, and the end, close to the bolt head, of the threaded rod is an unthreaded section; an oiling groove is formed in a bolt body inthe axial direction from the bolt head; an opening of the oiling groove is located in the bolt head; the unthreaded section is provided with an oil outlet channel communicating with the oiling groove;a tightening cap is arranged on the portion, below the bolt head, of the threaded rod; the tightening cap is in a taper shape and stretches out towards the outer side of the threaded rod; in addition, wavy anti-skid teeth are arranged at the lower end of the fastening cap; a deformable bolt cap is arranged above the bolt head in a sleeving mode; and an anti-rust oil storage cavity is formed in the bolt cap, and anti-rust oil is stored in the anti-rust oil storage cavity. The special anti-skid bolt has the advantages of being reasonable in structure, good in functionality and good in anti-looseness effect and anti-rust effect.

Description

technical field [0001] The invention relates to a special anti-skid bolt, belonging to a fastener. Background technique [0002] Fasteners are the most widely used basic parts, and are the general term for a class of mechanical parts used when two or more parts or components are fastened into a whole. There are many types and specifications of fasteners, each with different functions and uses, and the degree of standardization, serialization and generalization is extremely high. Among them, bolts are the most common type of fasteners. Conventional bolts generally include a head and a screw connected under the head. Bolts with this structure have a simple structure and general performance. In some occasions that require relatively high performance, traditional bolts can no longer meet the use requirements. Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provi...
