Problems solved by technology

[0002] A bolt is a kind of mechanical part, a cylindrical threaded fastener with a nut, a type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten and connect two For parts with through holes, currently, the bolts on the market have a similar structure, most of which are solid structures. The screwing method is to clamp the screw head with a wrench and then screw it. The bolts often rotate coaxially with the screwing. Screwing efficiency is low

Abstract

The invention discloses a sealing and fastening type bolt. The sealing and fastening type bolt comprises a screw head and a screw rod. The screw head is a hexagonal screw head with the cross section being a regular hexagon. The bottom of the screw head is fixedly connected with the screw rod. The vertical center axis of the screw head and the vertical center axis of the screw rod are in a straight line. The screw rod is of a cylinder structure and a sealing and fastening layer is arranged at the end, which is close to the screw head, of the screw rod in a wrapping manner, wherein the material of the sealing and fastening layer is an expanded graphite block. According to the abovementioned manner, the end, which is close to the screw head, of the screw rod is provided with a section of the sealing and fastening layer, so that the tightness and the sealability between the bolt and a hole can be guaranteed effectively and the coaxial rotation of the bolt and a screw cap during screwing can be avoided; the sealing and fastening type bolt is good in stability, capable of being fixed without rotating optionally, good in sealing effect and strong in practicality.

Description

technical field [0001] The invention relates to the field of fixing components, in particular to a sealing fastening type bolt. Background technique [0002] Bolt is a kind of mechanical parts. It is a cylindrical threaded fastener with a nut. It is a type of fastener composed of two parts, the head and the screw. It needs to be matched with the nut to fasten the connection between two For parts with through holes, at present, the bolts on the market have a similar structure, most of which are solid structures. The wrench is used to clamp the screw head and then screw it. The bolt often rotates coaxially with the screwing. Screwing efficiency is low. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a sealed fastening bolt, which can effectively ensure the fastening fit and sealing performance between the bolt and the hole, and avoid the coaxial rotation of the bolt and the nut during screwing. The situation, th...
