Abstract
The invention discloses a space scissor type telescopic mechanism, which is provided with at least two hinges (1) with shaft holes, wherein at least three hinge lugs (12) are radially distributed uniformly on a body (11) of each hinge (1); each hinge lug (12) is respectively hinged with at least one fork lever (2); and the fork levers (2) of the two hinges (1) are respectively crosswise hinged sequentially in pairs through pin shafts (3). In the invention, expansion and contraction of the mechanism can be realized through the rotation of the fork levers (2) or the movement of the hinges (1), the conditions of expansion and contraction are good, and no interference problems exist; the whole mechanism has slight shake in the processes of expansion and contraction and is safe and reliable; and the mechanism has stronger bearing capacity for force in different directions in the space. The mechanism can be superposed in series in multiple units, thus the mechanism has the characteristics of large telescopic amplitude, reasonable and stable structure and smooth and reliable operation.
Description
Technical field
The present invention relates to a kind of space mechanism device, specifically refer to a kind of space scissor type telescopic mechanism.
Background technique
Existing scissor type telescopic mechanism mostly is planar design greatly, uses comparatively common with single group plane scissors mechanism as expanding and lifting mechanism.200620025934.1) and be called the Chinese patent literature (number of patent application: 200710176158.4) though disclosed content all is to use two groups of scissors mechanisms simultaneously, cuts the fork face and be in same plane or be in two parallel planes for described two groups of " balanced type lifting platform " for example name is called the Chinese patent literature (number of patent application: of " scissors type bootstrapping lift platform ".Not interaction between the fork row is cut by mechanism in telescopic process, just use the fork row of cutting that are multiplied to improve bearing capacity simply.And after this many groups cut fork row The parallel combined, because its strong point is on the high side, needed driving force was just many, therefore will make respectively to cut the fork row and realize comparatively difficulty of steady lifting synchronously.In addition, because the horizontal component that external load produces also can make it produce bigger rocking on flexible direction in the working procedure, because its lateral force is poor, whole telescopic process all can play pendulum simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is, at suffered lateral force of existing extending means and warping force defect of insufficient, a kind of space scissor type telescopic mechanism is provided, and it is simple that the manufacturing process of this mechanism is wanted, and possess that flexible amplitude is big, resistance to compression bending resistance, characteristics such as stable.And as basic part, be equipped with drive system after, can be used for scissors fork elevating platform, lift, lifting moving and change tower, span support device etc.
Technical solution of the present invention is that described space scissor type telescopic mechanism referring to Fig. 1, has the hinge 1 at least two tape spool holes.Its technical characterstic is, is evenly distributed with at least three hinge ears 12 on the body 11 of described hinge 1 radially.Each cuts with scissors the hinged at least one fork arm 2 of difference on the ear 12.Corresponding successively respectively bearing pin 3 cross-articulation in twos of passing through of three fork arms 2 of described two hinges 1.
The invention has the beneficial effects as follows: this mechanism can realize the flexible of mechanism by the rotation or the moving of hinge 1 of above-mentioned driving rod member fork arm 2, facts have proved that it is flexible in order, does not have interference problem; Because the scissor type telescopic face has been modified into the flexible face more than three or three from two known faces that parallel, support mutually between each flexible face, make whole extending means very firm, shaking degree is very small in the process that stretches and shrink, so use safe and reliable; Because total is symmetrically distributed around the axis hole at hinge 1 center, so make its bearing capacity to the power of space different direction more intense.In addition, this mechanism can be as required as a unit multiple-unit overlapped in series.Therefore, it is big that this mechanism has flexible amplitude, rational in infrastructure stable, the stable working reliable characteristics.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the present invention, is denoted as among the figure:
The 1-hinge,
The 11-body,
12-cuts with scissors ear,
The 2-fork arm,
The 3-bearing pin,
The 4-packing ring.
Embodiment
Referring to accompanying drawing 1, this embodiment of the present invention aluminum alloy casting system hinge 1 of drawing materials.The external diameter of the body 11 of hinge 1 is ¢ 60mm, and shaft hole diameter is ¢ 40mm.The hinge ear that is evenly distributed on radially on each body 11 is three, so claim that this routine scissors type space multistory extending means is positive prismatic scissor type telescopic mechanism.Being hinged on the draw materials aluminum alloy web of wide 50mm, thick 30mm of the fork arm 2 that respectively cuts with scissors on the ear 12 tailors and forms the long 100mm of single pole, totally three bars.Above-mentioned member hinge 1 and fork arm 2, promptly evenly distribute radially three on the body 11 of hinge 1 and cut with scissors ear 12 with reference to the assembling of structure shown in the accompanying drawing 1 by the technical solution of the invention described above.Each cuts with scissors the hinged fork arm 2 of difference on the ear 12.Also as shown in Figure 1, with each three fork arms 2 of two hinges 1 of two above-mentioned routine scissors type space multistory extending means corresponding successively respectively by bearing pin 3 in twos cross-articulation promptly become two layers space scissor type telescopic mechanism.For making hinged fork arm 2 obtain safer rotate effect, on the bearing pin 3 between two fork arms 2 of described cross-articulation, also be set with a packing ring 4.
On probation to be proved to be effect remarkable through manufacturing experimently for the space scissor type telescopic mechanism of the present invention of Gou Chenging thus, reaches designing requirement fully.
Claims (2)
1. space scissor type telescopic mechanism, it is characterized in that, hinge (1) with at least two tape spool holes, be evenly distributed with at least three hinge ears (12) on the body (11) of described hinge (1) radially, each cuts with scissors ear (12) and goes up hinged at least one fork arm (2) respectively, corresponding successively respectively bearing pin (3) cross-articulation in twos of passing through of the fork arm (2) of described two hinges (1).
2. space scissor type telescopic mechanism according to claim 1, its feature also are, also are set with a packing ring (4) on the bearing pin (3) between two fork arms (2) of described cross-articulation.
