Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
As shown in Figures 1 to 3, a kind of rectangular pyramid composite structure, including connector 1 and connecting rod 2, two institutes
State connecting rod 2 to connect, middle part is pivotally connected to form a scissors unit, the middle part pivot points are the first articulated section 4；
Two or more two adjacent scissors units, two ends of the connecting rod 2 of its one end are mutual
Pivot joint forms a set of development agency that can be stretched to a direction, and the end pivot points are the second articulated section 3；
It is X to second pivot with the line of first articulated section 4 in a set of development agency
Socket part 3 perpendicular to the X to direction be Y-direction, define its vertical range for L；The connecting rod 2 is with institute
It is line of demarcation to state the first articulated section 4, and the L values of both sides are unequal, defines the larger one end of L values for first cuts
Formula portion 13, less one end of L values is the second scissors portion 14；Described the first of the adjacent scissors unit is cut
Formula portion 13 joins end to end with the second scissors portion 14, and the pyramid that being formed can stretch to a direction can open up machine
Structure；
The taper development agency is three or more than three, and the adjacent often set development agency is right at its
The second articulated section 3 answered is pivotally connected by the connector 1, the three-dimensional cone composite structure of composition.
In a set of development agency, as shown in Figures 2 and 3, that side of the first scissors portion 13
L value of the L values more than that side of the second scissors portion 14 so that the development agency becomes can be to a side
To flexible pyramid development agency, because the pyramid development agency is tapered, taper is equal to triangle
Stability so that the stretching, extension of the pyramid development agency or folding movement stabilization, Stability Analysis of Structures during work, energy
Fixed point work is realized, operating accuracy is improved；
Three or the taper development agency of the above, in the adjacent often set taper development agency correspondence
The second articulated section 3 be pivotally connected by the connector 1, constitute rectangular pyramid composite structure, the rectangular pyramid answer
Mechanism is closed under flexible two states, the change in size of its bottom is little, within 10% change, therefore relatively
, there is more preferable retractable support intensity in other traditional simple joint mechanisms；The adjacent pyramid development agency is mutual
Mutually play a supporting role, rigidity and intensity upon deployment increase, make to bear enabling capabilities change greatly；By institute
Stating a kind of rectangular pyramid composite structure can be folded, and it is installed and convenient in carrying, and the scope of application is more extensive.
Further, as shown in fig. 6, the taper development agency is four, rectangular pyramid composite structure is constituted；
The rectangular pyramid composite structure is upper wide in application, such as most lathes are all rectangular co-ordinate positioning and move,
And, rectangular pyramid composite structure structure endurance is best, make easy, low cost and durable.
Further, as shown in figure 3, the connecting rod 2 is the rod-like element of bending, its crooked place is located at institute
The first articulated section 4 is stated, the connecting rod 2 is cut in the one end in the second scissors portion 14 relative to described first
The inside lateral bending folding in one end in formula portion 13.
Make the L values of that side of the first scissors portion 13 more than the L values of that side of the second scissors portion 14,
So that the development agency becomes the pyramid development agency that can be stretched to a direction, present as triangle
Stability.
Further, the bending angle of the connecting rod 2 is 0-70 °.
Specific bending angle is 5 degree as shown in 4 figures, and specific measuring method is：By the same connection
Two the second articulated sections 3 on bar 2 are connected, and two the second pivots are made after 2 first articulated section of connecting rod 4
The line and above-mentioned horizontal line of the parallel lines of the line of socket part 3, two the second articulated sections 3 and the first articulated section 4
Angle be bending angle scope；Bending angle is located in the range of 0-70 degree, it is ensured that the taper can open up machine
Structure has sufficiently large extendable room, and then causes that a kind of structure of rectangular pyramid composite structure is more stablized
The connecting rod 2 is the rod-like element of bending, the one end of the connecting rod 2 in the first scissors portion 13
It is bent outwardly, is curved inwardly in the one end in the second scissors portion 14.
Make the L values of that side of the first scissors portion 13 more than the L values of that side of the second scissors portion 14,
So that the development agency becomes the pyramid development agency that can be stretched to a direction, present as triangle
Stability.
Further, as shown in figure 5, the connector 1 is mutual with one by the side of two the 11 of connecting plate
Determine the V-structure of angle composition；
The good stability of V-structure, it is ensured that a kind of rectangular pyramid composite structure is sufficiently stable when flexible.
Further, the connector 1 is located at the interior of the rectangular pyramid composite structure of taper development agency composition
Side.
Make the outer surface of the rectangular pyramid composite structure without other parts, it is to avoid rectangular pyramid composite structure outer surface
The damage of collision.
Further, the connector 1 is located at the outer of the rectangular pyramid composite structure of taper development agency composition
Side.
Facilitate the replacing of the connector 1, easily operation.
Further, as shown in Fig. 2 the big one end in the pyramid development agency opening is provided with drive mechanism, it is
Drive end 5；The small one end in opening, to be provided with executing agency, is working end 6；
The working end 6 of the taper development agency is provided with slide rail 7, and the slide rail 7 is U-shape structure, its closing
The first articulated section 4 of the working end least significant end is fixed at end, and other described the of the taper development agency
The rotary shaft of one articulated section 4 is flexible in the taper development agency outwardly in the taper development agency
When, the rotary shaft is slided in the slide rail.
The one side of the slide rail 7 clamps the end of the working end 6 so that can be along described during its motion
Slide rail 7 is slided, and structure is more stablized during slip；On the other hand, the slide rail 7 by executing agency with it is described
Working end 6 connects, and causes the executing agency from being revolved relative to the telescopic direction of the working end 6
Turn；So that the executing agency more facilitate, simplifies with being connected for the taper development agency, and then
So that a kind of structure of rectangular pyramid composite structure is simpler, operating accuracy is more preferable.
Know-why of the invention is described above in association with specific embodiment.These descriptions are intended merely to explain this
The principle of invention, and can not by any way be construed to limiting the scope of the invention.Based on herein
Explain, those skilled in the art associates other tools of the invention by would not require any inventive effort
Body implementation method, these modes are fallen within protection scope of the present invention.
