Abstract

The invention discloses a bolt with double hexagonal bolt heads, and belongs to the field of fasteners. The bolt with double hexagonal bolt heads is used for fasteners, and a head cavity is downwards processed at the top end of a bolt head; a screw cavity penetrating through a screw is machined in the bottom face of the head cavity, and the screw cavity communicates with side openings in the two sides of the bottom end of the screw. The screw cavity is connected with a limiting rod body through an internal thread, the bottom end of the limiting rod body is connected with an adjusting rod body, and the lower portion of the adjusting rod body is provided with a thread connected with a column body adjusting cavity in a limiting column; the limiting column is located in the screw cavity, and limiting top pieces are arranged on the two sides of the limiting column and located in the side openings. An outer supporting piece which moves downwards along with the adjusting rod body is arranged in the portion, above the limiting column, of the screw cavity, and the outer supporting piece makes contact with the inner side of the limiting top piece and stretches the limiting top piece outwards. The connection stability between the bolt and a nut can be improved through the improvement of a bolt structure, and a problem of looseness between the nut and the screw rod can be solved.

Description

technical field [0001] The invention belongs to the field of fasteners, in particular to a double hexagon head bolt. Background technique [0002] As a commonly used fastening structure in various fields, bolt fasteners are usually used for fixed connections between two structures, but one problem that bolt fasteners usually face is that after a period of use, due to problems such as vibration For the loosening of bolts, how to strengthen the easily loosened parts of bolts and nuts through reasonable structural improvement has become one of the technical problems to be solved in the industry. Contents of the invention [0003] The object of the present invention is to provide a double hexagon bolt head bolt, which can improve the stability of the connection between the bolt and the nut through the improvement of the bolt structure, and help to solve the problem of loosening between the nut and the screw rod. [0004] To achieve the above object, the present invention is a...
