Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
A kind of height and the adjustable holder of bottom width, including supporting table 1, inverted scissor type varistructure 2 and alterable height knot
Structure 3;
The bottom of the supporting table 1 is vertically installed with the alterable height structure 3 or inverted scissor type by end coupling 11
Varistructure 2, it is inverted scissor type connection structure 021 to enable the inverted scissor type varistructure;
As shown in Figure 1, the bottom when the supporting table 1 is vertically installed with the alterable height knot by end coupling 11
When structure 3, the bottom end of the alterable height structure 3 is connected with the inverted scissor type varistructure 2, and can by the inverted scissor type
The support of the bottom of structure changes 2 makes the supporting table 1 be set up on ground and is parallel to ground, enables the inverted scissor type varistructure 2
For inverted scissor type lower support structure 022;
As shown in Fig. 2, being connected when the bottom of the supporting table 1 is vertically installed with the inverted scissor type by end coupling 11
When structure 021, the bottom end of the inverted scissor type connection structure 021 is hinged with the alterable height structure 3, and can by the height
Structure changes 3 have been at least connected with another inverted scissor type varistructure 2, and the inverted scissor type varistructure 2 is enabled to be supported for inverted scissor type bottom
Structure 022, the supporting table 1 make the supporting table 1 be set up in ground by the support of the bottom of the lower support structure 022
Above and it is parallel to ground;
The inverted scissor type varistructure 2 includes two bending parts 21 and middle part articulation piece 22, and the bending part 21 is by two
Straight panel 211,212 consistent in length is integrally formed, wherein the plate end switching of a straight panel 211 has another straight panel 212
Plate end, switching junction are bending part 213;The bending part 213 of two bending parts 21 is oppositely arranged and by described
Portion's articulation piece 22 is hinged, and the connection of two bending parts 213 forms two opposite included-angle-changeables 202,203, any described
Its angle of included-angle-changeable 202 is open towards the bottom surface of the supporting table 1,203 its angle of another included-angle-changeable opening direction
Ground, two bending parts 21 are symmetrical set along the line of symmetry 201 of the inverted scissor type varistructure 2;
The inverted scissor type lower support structure 022 is by changing the either end of single or two bending parts 21 to institute
The vertical range for stating line of symmetry 201 realizes the adjustable structure of its bottom width.
The existing adjustable holder of some bottom widths is generally adopted by the flexible structure of scissors, and bottom width becomes smaller
While, support height can get higher therewith, while bottom width becomes larger, support height can be lower, width and
Highly negatively correlated relationship, holder in the prior art can only be adjusted by the rule it is variable, make its application be provided with it is larger
Limitation.
As shown in figure 3, the present invention proposes that one kind being not limited to now well-regulated height and the adjustable holder of bottom width,
It is used in the assembly of different number and various combination mode by inverted scissor type varistructure 2 and alterable height structure 3, realizes bottom
Width becomes larger, and highly gets higher, as shown in Figure 1, by single inverted scissor type lower support structure 022, multiple alterable height structures 3 with
And inverted scissor type connection structure 021 is end to end, makes the bottom width and height correlation of holder;And as shown in Fig. 2,
The bottom of holder is connected in series by two inverted scissor type lower support structures 022, is achieved bottom width and is become larger, and height becomes
Small rule, width and the negatively correlated relationship of height.The positive correlation and negative correlativing relation that the present invention realizes have been broken existing
The adjustment rule change of negative correlativing relation can only be had by having in technology, greatly expanded the application range of holder, made holder can
According to the change for carrying out structure under different use environments, there is adjustability, it is adaptable, and also mounting and adjusting is simple.In addition,
The whole height variable range of holder can be set by alterable height structure 3, and general setting quantity is more, the section of variation
It is bigger.
The setting of inverted scissor type varistructure 2, be the present invention to be not limited to now well-regulated height and bottom width adjustable
Holder foundation structure, by being oppositely arranged and by middle part articulation piece 22 for two two bending parts 213 of bending part 21
Be hinged, since the length of two straight panels 211,212 of bending part 21 is consistent, be made from it inverted scissor type varistructure 2 be one
The upper and lower and homogeneous symmetrical structure in left and right, the change width range in inverted scissor type varistructure upper and lower ends portion is identical, by changing
The vertical range for becoming single or two bending parts 21 either end to line of symmetry 201 realizes the adjustable structure of its bottom width.
In addition, the movable installation between two bending parts 21 can be realized by the installation of middle part articulation piece 22, pass through
Outer power drive bending part 21 realizes the change of included-angle-changeable 202,203, realizes the change of 2 bottom width of inverted scissor type varistructure,
Simple in structure, installing and dismounting is simple.
It should be noted that end coupling 11 is fixed on the bottom of supporting table 1 by screw.
Further description, the within angle A that the bending part 213 is formed are less than 180 °.It should be noted that within angle
A is the angle that two straight panels 211 and 212 switching connection of bending part 21 is formed.
Further description, the within angle A that the bending part 213 is formed are 30-135 °.
Further description, the alterable height structure 3 are scissors structure, and the scissors structure is by two connecting rods 31
