Description

Double-bent-rod mutual-supporting base

Technical Field

The utility model discloses be affiliated to the hard surface support base technique that mobility equipment used, specifically can steadily place mechanical structure base on unsmooth ground or flat subaerial such as unsmooth, hollow, can act as the base of multiple facility, for example perpendicular aircraft base, desk chair base, various long body type support bases etc..

Background

The base of the common movable ground support facility is only suitable for a plane and cannot adapt to the undulating ground, and the base has the defects that the base can be shaken and twists when being placed on the uneven ground, such as the traditional four-leg desk, the gliding base of a helicopter and the like.

Disclosure of Invention

The utility model discloses a solve foretell some traditional bases and can not adapt to the shortcoming of steadily placing in unsmooth ground, provide a hyperbolic pole formula base that mutually props up suitable for mobile device, its characterized in that:

the ground self-adaptive support device comprises a frame component and a support component, wherein each ground contact point of a curved rod of the support component is self-adaptive to the ground when the support component is placed, and a support position adaptive to the ground state is selected through synchronous twisting of a support rod to stably support the frame component;

the utility model discloses the advantage: the base is placed on the flat ground and the concave-convex ground, and internal twisting moment and external shaking cannot be generated between four contacts on the concave-convex ground generally.

Detailed Description

The following further explains, with reference to the accompanying drawings, the double-crank mutually supporting base (see fig. 1), which is characterized in that:

the frame component bracket (1) is approximately rectangular, four support legs are arranged, and a return spring (4) connecting port is arranged (see figure 2);

one end of each of the support component bent rods (2.1 and 2.2) is bent outwards and downwards to form a ground contact support arm, the other end of each of the support component bent rods is bent inwards and downwards to form another ground contact support arm, a central support arm (see figure 3) is arranged at the middle spine section, and connecting ports are arranged at two ends of the middle spine section and connected to the support (1);

two ends of a central supporting rod (3) of the support component are connected to a central supporting arm of the curved rod (2), and a return spring (4) connecting port is arranged at the middle end;

one end of the return spring (4) is connected to the bracket (1), and the other end is connected to the central support rod (3);

the crank rod (2.1) and the crank rod (2.2) are synchronously twisted, and when one is static, the other is also static;

when the curved levers (2.1, 2.2) are twisted, one of the ground contact arms descends and the other ground contact arm ascends.

The double-crank-rod mutual-supporting base basically operates:

before placement: the supporting and supporting component is leveled by the return spring (4) and is in a flat state;

after the plane is placed: is in a flat state as before placement;

after the concave-convex ground is placed: if the outer bent support arm of the curved rod (2.1) lands first, the curved rod (2.1) is twisted inwards until the inner bent support arm touches the ground, the central support arm of the curved rod (2.1) pushes the central support rod (3), the contact arms at two ends of the curved rod (2.2) touch the ground completely, the two outer bent support arms try to press the central support rod (3) and resist the moment that the two inner bent support arms try to stretch the central support rod (3), finally the central support rod (3) is shifted to the position of the balance point of four support legs of the four-support-arm average bearing support bracket (1), and then all parts stop deforming to present a stable placement state;

this example can serve as a base for a variety of installations, preferably mounted on a helicopter for reference (see fig. 4).

Debugging and improvement

The example is a basic double-crank four-fulcrum single-central-strut mutual-supporting base, and the lengths of all supporting arms are generally symmetrical and equal;

the present invention and the embodiments thereof have been described above without limitation, and the drawings are only one of the basic embodiments of the present invention, and the actual structure is not limited thereto, and in conclusion, if persons skilled in the art are informed by the teachings of the present invention, the structural modes and embodiments similar to the technical solutions are not creatively designed without departing from the spirit of the present invention, and all such modifications and embodiments shall fall within the protection scope of the present invention.
