Abstract

The invention discloses an automobile component fastening and connecting device which comprises an L plate. Through holes are formed in two panels of the L plate; a bolt penetrates through the throughholes, and comprises a first screw rod part; the first screw rod part is connected with a second screw rod part; the diameter of the second screw rod part is smaller than the diameter of the first screw rod part; the first screw rod part is in threaded connection with a first nut; the second screw rod part is in threaded connection with a second nut; and arc-shaped elastic pieces are fixed onto the first nut and the second nut. The automobile component fastening and connecting device provided by the invention is simple in structure and convenient to use; and through multiple ways, the nuts can be pre-tightened and extruded and are effectively prevented from vibration relaxation caused by vehicle running.

Description

Technical field: [0001] The invention belongs to the mechanical field, in particular to a fastening and connecting device for automobile parts. Background technique: [0002] Existing automobile connecting parts are inconvenient to connect parts perpendicular to each other, and the bolts and nuts are easy to fall off due to vibration after connection. Invention content: [0003] The purpose of the present invention is to provide a fastening and connecting device for automobile parts. The present invention has a simple structure and is easy to use. It realizes the pre-tightening extrusion of the nut through various methods, and effectively prevents the nut from loosening due to the vibration caused by the running of the vehicle. [0004] For solving the problems referred to above, technical scheme of the present invention is: [0005] A fastening and connecting device for automobile parts, comprising an L plate, through holes are formed on the two panels of the L plate, an...
