Fixing device for truck side fender

Abstract

The invention discloses a truck side baffle plate fixing device. A working tangent plane is arranged on a limiting shaft in the axial direction; an included angle between the working tangent plane anda horizontal plane is a specific angle; when being mounted, a side baffle plate is properly inclined so that an arc-shaped card slot opening just corresponds to a minimum width of a cross section ofthe limiting shaft, at this time, the limiting shaft can be clamped tightly to enter an arc-shaped card slot without applying a heavy force; the side baffle plate rotates at a certain angle around thelimiting shaft so that an upper connection bracket and a locking mechanism are fixed, at this time, the arc-shaped card slot opening and the minimum width of the cross section of the limiting shaft are staggered so that the arc-shaped card slot and the limiting shaft are closely adhered, and the falling and loosening risks are avoided; when the disassembly is needed, a reverse operation is performed, the side baffle plate can be separated by only needing to pull outwards with a relatively small force, thereby effectively improving the assembly and disassembly convenience of the side baffle plate; furthermore, through matching of a limiting block and a limiting bracket, the effect that the side baffle plate vibrates in front and rear directions can be limited.

Description

technical field [0001] The invention relates to the field of vehicle side baffles, in particular to a fixing device for a truck side baffle. Background technique [0002] With the rapid development of the economy, people's requirements for trucks are getting higher and higher. At present, mainstream heavy truck tractors are equipped with side baffles between the front and rear wheels, which can increase the appearance and also play a protective role. With the popularization of manually detachable side baffles, the reliability and convenience of disassembly and assembly of side baffles have become the focus of attention. [0003] The heavy truck side baffle device currently on the market consists of a side baffle, an upper connecting bracket, a lower connecting bracket, a mounting strut, etc., each set at the front and back. The side fenders are first fixed with the upper and lower connecting brackets, then the installation struts and the fender brackets are fixed and instal...

AI Technical Summary

Problems solved by technology

[0004] When the side baffle is fixed to the rotating shaft through the lower connecting bracket, it can be fixed through the plastic deformation of the rubber through the card slot and the rotating shaft of the mounting strut. However, due to the strength, the hardness of the rubber is high, and it is extremely laborious to install and disassemble. , which affects the convenience of disassembly and assembly; secondly, the acceleration and deceleration of the vehicle during driving will cause the side baffle to move slightly relative to the whole vehicle, which will cause the wear of the upper locking mechanism and the lower rotating mechanism, and affect the service life
