Abstract

The invention discloses a novel bolt connection structure. The bolt connection structure comprises an upper connecting plate, a lower connecting plate, a bolt and a nut. Unthreaded hole are formed in the upper connecting plate and the lower connecting plate. The bolt is inserted into the connecting plate from bottom to top. The extending-out end of the upper connecting plate is fastened through the nut. Countersunk head grooves are formed in end portions of the unthreaded holes of the upper connecting plate and the lower connecting plate. Roughing treatment and relative post-processing are conducted on surfaces of the countersunk grooves, so that connection strength of the bolt is enabled to be more reliable. According to the novel bolt connection structure, countersunk groove structures are formed in the end portions of the unthreaded holes of the connecting plates in the bolt connection structure, the countersunk head grooves can gain high surface roughness after the roughing treatment is conducted on the surfaces, so that the nut is enabled to produce enough pre-tightening force and good anti-skidding capacity at fastening connection time. Meanwhile, the countersunk groove structure design is adopted, so that utilization of a gasket or a washer is eliminated, assembling procedures of bolt connection is reduced, and production cost is reduced to a certain degree.

Description

technical field

[0001] The invention relates to a bolt connection structure, in particular to a novel bolt connection structure which can reduce the use of gaskets and ensure good connection strength, and belongs to the technical field of mechanical manufacturing. Background technique

[0002] A bolt is a type of fastening connection consisting of a head and a screw rod. When used, it needs to cooperate with a nut to fasten two parts with light holes. This connection structure is usually called a bolt connection structure. When the bolt connection is used, the bolt and the nut can be fastened or separated only by screwing the nut around the bolt in a clockwise or counterclockwise direction, so the bolt connection structure is a detachable connection.

[0003] Usually, when bolts are used between mechanical parts, gaskets or washers (commonly used elastic gaskets and anti-skid gaskets) are set between the nut and the end face of the mechanical parts to enhance the pre-tighten...
