The invention provides a foldable support leg mechanism. The foldable support leg mechanism comprises an upper support leg, a lower support leg and a middle support leg, wherein the upper support leg and the lower support leg are respectively hinged to the upper and lower ends of the middle support leg through support leg connecting plates; the lower end of the lower support leg is in cup joint with a cushion plate support leg; a shaft hole and a chute corresponding to each other are formed in the lower support leg and the cushion plate support leg; an adjustable shaft sleeve is arranged in the shaft hole; a spring is arranged between the lower support leg and the cushion plate support leg; one end of the spring is fixed on the lower support leg, and the other end is fixed on the chute through a bolt; and a support leg lower cushion plate is arranged at the bottom of the cushion plate support leg. The foldable support leg mechanism can effectively support the ground to bear the load of the front half part of a semitrailer when a tractor is decoupled from the semitrailer. The mechanism uses the spring for controlling gears through the fit of several pin shafts to realize adjustable support of the semitrailer mechanism. The foldable support leg mechanism can preferably solve the problem of supporting the load of the front half part of the semitrailer, reduces the manual operation and the cost, and has excellent economic and social benefits.
Description
technical field [0001] The invention relates to an automobile part, in particular to a foldable outrigger mechanism. Background technique [0002] At present, the domestic transportation industry mainly focuses on long-distance semi-trailer transportation, and outriggers are used more frequently. Therefore, the outrigger mechanism must meet the following requirements: [0003] ① The outrigger mechanism is easy to operate, and the outrigger can be raised and lowered to a suitable position through simple actions; [0004] ② The structure of the outrigger is simple, through the simple mechanical principle, the requirements are met, and the cost is low; [0005] ③ The outriggers are safe and firm, and can bear the overload load of the trailer; [0006] To sum up, the general outrigger mechanism can meet the requirement ③, but it can’t meet the requirement ①② or can’t meet it very well. The existing support leg is to rotate the handle to drive the gear inside the support leg,...
