Abstract
The utility model relates to an automatic filtering triangular supporting leg, comprising a fixing bracket, wherein bidirectional oil cylinders are respectively arranged at the both sides of the top of the fixing bracket and are movably linked with one end of a straight pull arm through pin shafts; the other end of the straight pull arm is mounted at the bottom of the fixing bracket; and the fixing bracket, the bidirectional oil cylinders and the straight pull arm are connected to form a triangular structure. The automatic filtering triangular supporting leg provided by the utility model has the beneficial effects of simple structure and convenience for operation. By using a triangular structure consisting of the fixing bracket, the bidirectional oil cylinders and the straight pull arm, the supporting leg is more stable and the height of the supporting leg is adjusted by controlling the stretching of the bidirectional oil cylinders. Therefore, the supporting leg can automatically adjust a state to be adapted to different ground heights.
Description
Technical field
The utility model relates to a kind of supporting leg, and especially a kind of for motor vehicle automatic lifting gusseted leg belongs to the auxiliary component of vehicle technical field.
Background technology
Traditional be used for the supporting leg that vehicle supports and generally comprise following several kinds: wherein a kind of supporting leg directly is connected with automotive frame or vehicle frame, its up-down mode be about vertical lift; Another kind of supporting leg is installed in the two ends of vehicle level crossbeam, and can extend to two ends, its up-down mode also be about vertical lift; Also have a kind of supporting leg can support be fixed on the crossbeam, and rely on the flexible drive supporting leg torque arm of oil cylinder to stretch to form cam mechanism to both direction simultaneously, play comparatively stable supporting role.But more than the bearing length of several kinds of supporting legs fix, can not carry out freely adjusting according to floor level, make its holding state unstable.
The utility model content
The purpose of the utility model is: to the problem that above-mentioned prior art exists, propose a kind of simple in structurely, can carry out self-align automatic lifting gusseted leg with the ground height.
In order to reach above purpose; The automatic lifting gusseted leg of the utility model comprises fixed support, and its improvements are; Both sides, said support bracket fastened top are provided with two-way cylinder respectively; Said two-way cylinder is through an end active link of bearing pin and vertical pulling arm, and the other end of said vertical pulling arm is installed in support bracket fastened bottom, and fixed support, two-way cylinder and vertical pulling arm are interconnected to form three-legged structure.
It is that the junction of said two-way cylinder and vertical pulling arm is provided with Universal stand that the utility model further improves.
The utility model further improves again, and said fixed support is through bearing pin and two-way cylinder active link, and said two-way cylinder is provided with bidirectional hydraulic lock, and said fixed support is through bearing pin and vertical pulling arm active link.
The beneficial effect of the utility model is: the automatic lifting gusseted leg of the utility model; Simple in structure; Easy to operate, as to adopt fixed support, two-way cylinder and vertical pulling arm to form three-legged structure makes this supporting leg comparatively stable; And adjust the height of supporting leg through stretching of two-way cylinder of control, thereby cause this supporting leg can the automatic compensation state to adapt to different floor levels.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the birds-eye view of the utility model embodiment one.
The specific embodiment
Embodiment one
The automatic lifting gusseted leg of present embodiment; Its structure is as shown in Figure 1, comprises the fixed support 1 of cross section isosceles trapezoid, and the both sides, top of fixed support 1 are equipped with a two-way cylinder 2; Two-way cylinder 2 is through an end active link of bearing pin and vertical pulling arm 4; The other end of vertical pulling arm 4 is installed in the bottom of fixed support 1, makes fixed support 1, two-way cylinder 2 and vertical pulling arm 4 be interconnected to form three-legged structure, and is provided with Universal stand 3 in the junction of two-way cylinder 2 and vertical pulling arm 4.Fixed support 1 is through bearing pin and two-way cylinder 2 active links in addition, and two-way cylinder 2 is provided with bidirectional hydraulic lock, and fixed support 1 is through bearing pin and vertical pulling arm 4 active links.
During actual the use, this supporting leg is fixedly mounted on the automotive frame, first start a car before the use; And power takeoff hung up, make power takeoff drive oil pump output high pressure oil to fluid control valve, the switch of operating hydraulically operated control cock is controlled two-way cylinder 2 activities then; Supporting leg is moved up and down form a stable three-legged structure; The locking bidirectional hydraulic lock is fixed three-legged structure, to realize supporting role.
Except that the foregoing description, the utility model also can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
