Abstract
A contractible shear mode set half-round surface and arc surface comprises a plurality of hinged shear mode units, and the shear mode units comprise hinges, upper-layer plates and lower-layer plates, wherein the upper-layer plates and the lower-layer plates are stacked and the hinges sequentially penetrate through the upper-layer plates and the lower-layer plates; plate hinge points are arranged at the two ends of each upper-layer plate and the two ends of each lower-layer plate, the two ends of each upper-layer plate are hinged to the plate hinge points of the corresponding adjacent lower-layer plate through the plate hinge points for forming contractible radial shear mode sets after all the shear mode units are arranged in a linear mode, and the plate hinge points of the upper-layer plates and the plate hinge points of the lower-layer plates are unit hinge points; in the expanding direction of the radial shear mode sets, the width of the upper-layer plates and the width of the lower-layer plates are gradually increased; the side edges of more than one radial shear mode set are hinged for forming a fan-shaped contractible structure. According to the contractible shear mode set half-round surface and arc surface, fan-shaped mechanisms are stable in structure, can be mutually and stably connected, can be used in booth arrangements of exhibitions, toys and fan frameworks and are wide in application range but not limited in any field.
Description
Technical field
The present invention relates to scissors field of mechanisms, particularly a kind of contractile scissors pay group semi circular surface and cambered surface.
Background technique
Scissors mechanism has application and development very widely at present, as folding tent, contractile door curtain, lift, foldable desk lamp or mechanical arm etc.Its feature is that magnification is large, and extensible long Distance geometry longspan, takes up space very little, be therefore applied in many industries after it shrinks.
What adopt in the application of current most of scissors mechanism is one side scissors mechanism or two parallel scissors mechanism, and as door curtain employing is one side scissors mechanisms, and what lift adopted is two parallel scissors mechanisms.The major defect of most scissors mechanism is being subject under multi-direction power effect, and the intensity of the structure on its Impact direction and rigidity are not enough to the load-bearing effect of bearing this power, and easily askew folding occurs, Security is not high yet.In addition, the load-carrying ability of current scissors mechanism is not high yet, and these weakness limit its application widely.If use two parallel scissors mechanism, although can load-carrying ability be strengthened, the asynchronous problem of work between Liang Ge scissors mechanism, can be there is, cause the working platform of lift to run the problems such as not steady.
Summary of the invention
For the problems referred to above, the object of the invention is to propose a kind of contractile scissors and pay group semi circular surface and cambered surface.
For reaching this object, the present invention by the following technical solutions:
A kind of contractile scissors pay group semi circular surface and cambered surface; Comprise some scissors unit be hinged, described scissors unit comprises hinge, mutually stacking top plate and lower plywood, and described hinge is successively through described top plate and lower plywood; The two ends of described top plate and lower plywood are provided with plate articulating point, some described scissors unit are according to after linear array, the two ends of described top plate are hinged with the plate articulating point of adjacent described lower plywood respectively by described plate articulating point, form telescopic radial scissors group, the articulating point of described top plate and described lower plywood is unit articulating point;
Along the expansion direction of described radial scissors group, described top plate and lower plywood width increase gradually; The side of the above radial scissors group is hinged, and forms fan-shaped Collapsible structure.
Preferably, described radial scissors group is according to arrayed, and the described unit articulating point of corresponding position is hinged, and the above radial scissors group is interconnected.
Preferably, described top plate and lower plywood are made up of a rectangular slab and two set square triangles, and two described set square triangles are separately fixed at the two ends of described rectangular slab.
Preferably, described set square triangle is isosceles triangle.
Preferably, the position of described hinge successively near its side margin from described top plate and described lower plywood is passed.
Beneficial effect of the present invention: so fan-shaped mechanism structural stability, forms stable connection each other, can arrange as the exhibition booth of exhibition, the use such as toy, ribs of the fan, of many uses and be not limited in any field.
Accompanying drawing explanation
Fig. 1 is the half opened condition structural representation of one embodiment of the present of invention;
Fig. 2 is the complete closure status architecture schematic diagram of one embodiment of the present of invention;
Fig. 3 is the full open mode structural representation of one embodiment of the present of invention.
Wherein: top plate 1, lower plywood 2, hinge 3, plate articulating point 4.
Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
A kind of contractile scissors pay group semi circular surface and cambered surface; Comprise some scissors unit be hinged, described scissors unit is made up of hinge 3, mutually stacking top plate 1 and lower plywood 2, described hinge 3 is successively through described top plate 1 and lower plywood 2, the two ends of described top plate 1 and lower plywood 2 are provided with plate articulating point 4, some described scissors unit are according to after linear array, the two ends of described top plate 1 are hinged with the plate articulating point 4 of adjacent described lower plywood 2 respectively by described plate articulating point 4, form telescopic radial scissors group, described top plate 1 is unit articulating point with the articulating point of described lower plywood 2;
Along the telescopic direction of described radial scissors group, described top plate 1 and lower plywood 2 width reduce gradually; The side of the above radial scissors group is hinged, and forms fan-shaped Collapsible structure.
As shown in Figure 1, be state that fan-shaped Collapsible structure is semi-open;
As shown in Figure 2, be state that fan-shaped Collapsible structure closes completely;
As shown in Figure 3, be the state that fan-shaped Collapsible structure closes completely,
Fan-shaped mechanism structural stability like this, forms stable connection each other, can arrange, the use such as toy, ribs of the fan as the exhibition booth of exhibition, of many uses and be not limited in any field.
Described radial scissors group is according to arrayed, and the described unit articulating point of corresponding position is hinged, and the above radial scissors group is interconnected.
Being interconnected of corresponding position, thus form stable Collapsible structure, improve the practicability of product.
Described top plate 1 and lower plywood 2 are made up of a rectangular slab and two set square triangles, and two described set square triangles are separately fixed at the two ends of described rectangular slab.
The horn structure of the distinctive list structure of rectangular and set square triangle, makes Collapsible structure light flexibly in telescopic process, reduces surface friction drag each other, save power.
Preferably, described set square triangle is isosceles triangle.
Described hinge 3 passes near the position of its side margin successively from described top plate 1 and described lower plywood 2, and make use of every block top plate 1 or lower plywood 2 so better becomes Collapsible structure and become the part launching covering of the fan, improves raw-material value.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present invention, and these modes all will fall within protection scope of the present invention.
