Abstract
The utility model relates to an automatic multipurpose folding supporting frame, which mainly solves the problems that similar supporting frames are irregular and can not automatically support after supporting, and the supporting frame is formed by assembling a supporting rod, a connecting block, a rotating piece and a spring, wherein the connecting block is provided with a round hole and a Z-shaped hole, particularly the central line of the Z-shaped hole and the central line on the connecting block have an included angle of less than 90 degrees, thus, the rotating direction of the supporting rod is changed, the supporting frame has regular appearance after supporting, the rotating piece is provided with a tooth-shaped hole and a sliding hole, and the supporting rod can synchronously and automatically support with the addition of the rotating piece and the spring, thus, the supporting frame can be generally applied to conveniently-carried folding chairs, tables and beds and supporting frames capable of bearing various objects.
Description
Technical field
The utility model relates to a kind of automatic multi-purpose folding support frame, and for people life conveniently provides various requirement, portable bracing frame is as energy easy to carry (not automatic) folding table, chair, bed that supports and carry the bracing frame of various objects automatically.
Background technology
In the prior art, the various collapsible bracing frame of being seen with find, all exist the support bar rotation direction and be parallel to the rotation of bracing frame center line, such result is after this folding support frame supports, and corresponding upper support bar and lower support bar exist irregular generation skew; Such folding support frame just influences its aesthetics and the scope of application widely, so seldom see such product on the existing market.
In the prior art, the various collapsible bracing frame of being seen with find, the pivot pin of support bar or rivet all exist an end and fix, because support bar is the requirement activity, but the fixing shortcoming of an end is that firm stable is poor, to the intensity and the stability requirement height of pivot pin or rivet.
In the prior art, the automatic support function that does not have folding support frame.
The patent No. 89203774.1 multi-purpose folding bracing frames for example, main contents according to its application are exactly a hollow support body, its support bar rivet connecting portion of such structure is a straight flange, exist the support bar rotation direction equally and be parallel to the rotation of hollow support body center line, such bracing frame supports the corresponding upper support bar in back and the lower support bar exists misalignment, can produce bigger skew, and its rivet to be connected and fixed be that an end is fixing, its firm stable is just poor, does not have automatic support function.
Summary of the invention
The technical problems to be solved in the utility model, it is a kind of automatic multi-purpose folding support frame, bracing frame outward appearance after particularly supporting is neat, the support bar skew of corresponding top and the bottom and few bracing frame, and can support automatically, and it is folding easy to carry, the automatic multi-purpose folding support frame of applied range, this automatic multi-purpose folding support frame can be designed to automatic multi-purpose folding support frame and not automatic multipurpose folding bracing frame as requested respectively, and does not change outward appearance and actual the use.
In order to solve the problems of the technologies described above, a kind of automatic multi-purpose folding support frame of the utility model, it comprises that members such as contiguous block, rotatable lamella, support bar, spring form; The frame that circular hole and Z-shaped hole, fixed leg and periphery are arranged on the contiguous block, whether circular hole on the contiguous block decides setting according to designing requirement, it on particularly Z-shaped centerline hole and the contiguous block angle line structure that is less than 90 degree, support bar interts on Z-shaped hole, presses Z-shaped centerline hole to rotation; Scallop and sliding eye are arranged on the rotatable lamella, and rotatable lamella and scallop are to come the support bar of push-and-pull simultaneously to rotate by rotating, and sliding eye is mounted in and is used for the stable rotation sheet on the fixed leg and rotates and sliding trace; Pin hole is arranged on the support bar, support bar is plugged on the pin hole that pivot pin is installed in Z-shaped hole, is used for fixing the support bar fulcrum; By several springs are housed, spring one end links to each other with contiguous block between contiguous block and the rotatable lamella, and the other end links to each other with rotatable lamella, is to be used for push-and-pull rotatable lamella expansion bracing frame; Rotatable lamella and spring can be installed in the two sides of contiguous block arbitrary; Form an automatic bracing frame by above-mentioned member, just become nonautomatic multipurpose folding bracing frame as assembling with support bar and contiguous block two members.
By the member combination, can form different bracing frames in the technique scheme, when requiring automatic multi-purpose folding support frame, then assemble by members such as contiguous block, rotatable lamella, support bar, springs; When only requiring the multipurpose folding bracing frame, then assembling just becomes with support bar by contiguous block.
The effect of the folding support frame that the utility model is automatic multi-purpose is, having adopted on Z-shaped centerline hole and the contiguous block is an angle line structure that is less than 90 degree between the center line, after such bracing frame supports, the support bar skew of corresponding top and the bottom just reaches few, outward appearance is neat, and is an automatic multi-purpose folding support frame.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Automatic multi-purpose folding support frame in the present embodiment, main by the support bar in the accompanying drawing 1 (11), spring (9) in contiguous block (2) and the accompanying drawing 3 and rotatable lamella (6) are formed, circular hole (5) and four Z-shaped holes (3) are arranged on the contiguous block in the accompanying drawing 2 (2), four support bars (11) intert in four Z-shaped holes (3), intert with pivot pin again and be fixed in the pin hole (4), support bar (11) rotation direction is always rotated by Z-shaped centerline hole (10), four or two springs (9) are arranged between contiguous block (2) and the rotatable lamella (6), one end of each spring (9) is connected with contiguous block (2), and the other end just is connected on the rotatable lamella (6), again rotatable lamella (6) is installed in the fixed leg (12) on accompanying drawing 6 contiguous blocks (2), make it keep enough spaces to be beneficial to spring (9) telescopic movable, when folding, tie with a rope, decontrol rope during use and just can launch bracing frame, thereby realize automatic multi-purpose folding support frame.
Multipurpose folding bracing frame in the present embodiment, mainly form by the support bar in the accompanying drawing 1 (11), contiguous block (2), circular hole (5) and Z-shaped hole (3) are arranged on the contiguous block in the accompanying drawing 2 (2), four support bars (11) intert in four Z-shaped holes (3), intert with pivot pin again and be fixed in the pin hole (4), support bar (11) rotation direction is always rotated by Z-shaped centerline hole (10), thereby realizes the multipurpose folding bracing frame.
