The upper end of the support rod is mounted on the different hinge joints on fixed supporting leg case, support rod from the upper end of support cylinder
Lower end the different hinge joints on supporting leg are mounted on from the lower end of support cylinder.
Supporting leg disk is installed on the supporting leg.
It is fully operational state when the support rod and support cylinder are perpendicular to ground, under the fully operational state, support
The distance between the distance between two hinge joint of oil cylinder two hinge of support rod.
The fixed supporting leg case includes upper cover plate and left and right side plates.
The supporting leg disk includes straight lower plate and is located at the left and right side plates that lower plate two sides are inverted V-shaped shape.
The present invention is easy to be laid out, and carrying is stablized, and structure is simple, and securely and reliably, supporting leg span is big, and work efficiency is high, manufacture
It is lower that cost is substantially lower than existing telescopic legs.

Specific embodiment
To further understand the features of the present invention, technological means and specific purposes achieved, function, below with reference to
Present invention is further described in detail with specific embodiment for attached drawing.
As shown in figure 1 and 2, present invention discloses a kind of support leg device, including the fixed supporting leg case being welded on vehicle frame,
Symmetrically there are two supporting mechanism, which includes support rod, support cylinder and supporting leg for installing on the fixed supporting leg case,
The upper end of support rod and support cylinder, which is respectively articulated with, to be mounted on fixed supporting leg case, supporting leg respectively with support rod, support cylinder
Lower end hingedly install.Oil cylinder guide plate is also hingedly installed on the fixed supporting leg case, the lower end of the oil cylinder guide plate and branch
Support leg is hingedly installed.Using the rotation between support rod, support cylinder and oil cylinder guide plate three, realizes and shrink and be unfolded behaviour
Make, is able to carry out more stable carrying support.
The upper end of the oil cylinder guide plate and the upper end of support cylinder are mounted on the same hinge joint on fixed supporting leg case, oil
The lower end of cylinder guide plate is mounted on the different hinge joints on supporting leg from the lower end of support cylinder.The upper end of support rod and support oil
The upper end of cylinder is mounted on the different hinge joints on fixed supporting leg case, and the lower end of support rod and the lower end of support cylinder are mounted on support
Different hinge joints on leg.To realize the state for withdrawing and being fully deployed completely.The hinge joint 12 of oil cylinder guide plate upper end, branch
The hinge joint 11 of strut upper end, the hinge joint 13 of support cylinder lower end, the hinge joint 14 of oil cylinder guide plate lower end, support rod lower end
Hinge joint 15.
Supporting leg disk is installed, which includes straight lower plate and be located at lower plate two sides and be on the supporting leg
The left and right side plates of inverted V-shaped shape.Using supporting leg disk, more whole can fasten on the ground.
It is fully operational state when the support rod and support cylinder are perpendicular to ground, under the fully operational state, support
The distance between the distance between two hinge joint of oil cylinder two hinge of support rod.
The fixed supporting leg case includes upper cover plate and left and right side plates.
In the present invention, under two supporting mechanism fully operational states, it is launched into " eight " shape.Then entire contracting after withdrawing completely
It is back in supporting leg fixed case.
The specific course of work are as follows: support cylinder opens the hinge joint 13 of driving supporting leg along post upper hinge joint 11
For the center of circle, to be moved on the circular arc of a length of radius of support rod, the hinge joint 14 of supporting leg and oil cylinder guide plate is along oil cylinder guide plate
The hinge joint 12 of upper end is the center of circle, moved on the circular arc of a length of radius of oil cylinder guide plate until support rod and support cylinder are in
Plumbness, at this point, be in " eight " shape after the supporting leg expansion of two supporting mechanisms, whole device smoothly loaded object.Branch
The process that leg is withdrawn is the inverse process of aforesaid operations.
It should be noted that these are only the preferred embodiment of the present invention, it is not intended to restrict the invention, although ginseng
According to embodiment, invention is explained in detail, for those skilled in the art, still can be to aforementioned reality
Technical solution documented by example is applied to modify or equivalent replacement of some of the technical features, but it is all in this hair
Within bright spirit and principle, any modification, equivalent replacement, improvement and so on should be included in protection scope of the present invention
Within.
