Embodiment Construction

[0013] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the present invention includes a bolt 1, a nut 2, a connected part A3, a connected part B4, a lock block A5 and a lock block B6, and the connected part A3 and the connected part B4 are processed with holes for the bolt 1 to pass through. The bolt hole, wherein the bolt hole A7 on the connected part A3 is a rectangular hole (that is, the cross section of the hole is rectangular), and the long side of the rectangular hole is in the shape of a rectangular tooth. The bolt hole B8 on the connected piece B4 is a commonly used round hole. The lock block A5 and the lock block B6 are installed in the rectangular hole, and the side opposite to the rectangular tooth surface of the rectangular hole is processed with a rectangular tooth groove that can be engaged with the rectangular tooth of the rectangular hole, and the end surface opposite to the bolt 1 is an arc surface , the lock block A5 and the loc...

Abstract

The invention discloses an adjustable bolt connection structure which comprises a bolt, a nut and connected pieces, wherein a bolt hole in at least one of the connected pieces is a rectangular hole of which the long sides are toothed; two locking pieces with teeth mesh with teeth on the rectangular hole and are installed in the rectangular hole; and after installation, the cambered surfaces of the two locking pieces facing towards one end of the bolt surround both sides of the bolt. The adjustable bolt connection structure can solve the problem that the existing bolt connection can not be installed due to the dislocation of the bolt hole of the connected piece, so that the bolt connection can still be adopted when the machining accuracy of the connected piece is not satisfactory.

Description

technical field [0001] The invention relates to a bolt connection structure, in particular to an adjustable bolt connection structure which is mainly used for the connection of steel structures. Background technique [0002] Commonly used connection methods for steel structures include welding, riveting and bolting. Bolt connection is widely used because of its convenient construction and repeated installation and disassembly. However, the bolted connection has high requirements on the manufacturing accuracy of the connected parts. When the geometric dimension accuracy of the connected parts cannot meet the requirements, it cannot be guaranteed that the bolt holes of the connected parts are aligned during installation, and the dislocation of the bolt holes will make the bolts It cannot be installed because it cannot pass through, so the use of bolted connections is subject to certain conditions. Contents of the invention [0003] The purpose of the present invention is t...
