Problems solved by technology

The main disadvantage of most scissor mechanisms is that under the action of multi-directional force, the strength and rigidity of the structure in the direction of the force are not enough to bear the load-bearing effect of the force, it is prone to distortion, and the safety is not high
In addition, the load capacity of the current scissor mechanism is not high, and these weaknesses limit its wider application
If a double parallel scissor mechanism is used, although the load capacity can be enhanced, there will be a problem of asynchronous work between the two scissor mechanisms, resulting in problems such as unstable operation of the working platform of the elevator

Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0030] Such as Figure 1 to Figure 4 As shown, a multi-shaped annular scissor mechanism that can be stretched and changed, including an inner convex part and an outer convex part;

[0031] The inner convex part includes at least one inner convex scissor unit 11, and the inner convex scissor unit 11 includes an inner hinge shaft 15, an inner convex upper layer plate 12 and an inner convex lower layer plate 13;

[0032] The inner convex upper layer 12 and the inner convex lower layer 13 are stacked on each other, and the inner hinge shaft 15 passes through the inner convex upper layer 12 and the inner convex lower layer 13 in turn; the inner convex upper layer 12 and the inner convex lower layer Two inner convex hinge points 14 are respectively arranged on the plate 13;

[0033] In the inner convex ...

Abstract

The invention relates to a telescopically changing multiform annular shear structure, which comprises inner convex parts and outer convex parts, and is characterized in that the inner convex part at least comprises an inner convex shear unit, the inner convex shear unit comprises an inner hinge shaft, an inner convex upper plate and an inner convex lower plate; the inner convex upper plate and the inner convex lower plate are mutually stacked, the inner hinge shaft sequentially passes through the inner convex upper plate and the inner convex lower plate; both the inner convex upper plate and the inner convex lower plate are provided with two inner convex hinge points; the outer convex part comprises a plurality of outer convex shear units which are connected end to end, each outer convex shear unit comprises an outer hinge shaft, an outer convex upper plate and an outer convex lower plate; the outer convex upper plate and the outer convex lower plate are mutually stacked, and the outer hinge shaft sequentially passes through the outer convex upper plate and the outer convex lower plate; both the outer convex upper plate and the outer convex lower plate are provided with two outer convex hinge points; and a plurality of inner convex parts and outer convex parts are mutually hinged to form the telescopically changing multiform annular shear mechanism with an upper inner ring and a lower inner ring.

Description

technical field [0001] The invention relates to the field of scissor mechanism, in particular to a multi-shaped annular scissor mechanism that can be stretched and changed. Background technique [0002] The scissor mechanism has a wide range of applications and developments, such as foldable tents, retractable door curtains, elevators, foldable desk lamps or robotic arms, etc. It is characterized by a large expansion ratio, can be extended for a long distance and a large span, and when it shrinks, it occupies a small space, so it is used in many industries. [0003] What adopt in the application of most scissor mechanism at present is single-sided scissor mechanism or double parallel scissor mechanism, what adopt as door curtain is single-sided scissor mechanism, what elevator adopts is double parallel scissor mechanism. The main disadvantage of most scissor mechanisms is that under the action of multi-directional force, the strength and rigidity of the structure in the dir...
