Abstract
The utility model aims to provide a three-legged fixing base for a column type easel. Stability of the easel can be ensured after long-term use by changing a structure of the base. In order to achieve the purpose, the three-legged fixing base for the column type easel is mounted on a spine, a movable groove is formed in the center of the spline longitudinally, the column type easel with an upper pull shell and a lower pull shell is movably connected in the movable groove, a left leg and a right leg are fixed in the movable groove, and each of the left and right legs is composed of an upper support rod and a lower support rod in movable connection. By the technical scheme, by changing of the integral structure and on the premise that original functions of the easel are kept, stability of the bottom of the easel is improved, and height of the easel is adjusted within a larger range. Even if some wear is caused by long-term use, stability of an integral easel body is unaffected.
Description
Technical field
The utility model relates to a kind of pillar easel, relates in particular to a kind of tripod firm banking for pillar easel.
Background technology
A kind of instrument of commonly using when easel is drawing.Easel of the prior art is of a great variety, but all also has a problem, and the shared position of easel is excessive, is inconvenient to deposit and transport.If conveniently deposit and transport, easel certainly will to be redesigned on the whole.And the required raw material of complicated easel is also many.Because timber price constantly promotes.We are guaranteeing that easel firmly under prerequisite, also wishes to save as far as possible material.
In order to solve such problem, applicant discloses a kind of pillar easel in the utility model < of patent No. CN201220689622.6 < pillar easel > >, simple in structure, result of use is good.Reduce material and taken up space with institute, can be applicable to the drawing board of various models simultaneously.In order to reach described object, the technical scheme that the utility model adopts is pillar easel, comprise backbone, backbone center is longitudinally provided with loose slot, in described loose slot, be connected with and draw shell and drop-down shell, described backbone bottom to be laterally provided with fixing shelves, be also provided with L shaped feet, described L shaped feet top is movably connected in the loose slot of described backbone, and L shaped feet bottom is fixed on the junction between backbone and fixing shelves.Owing to having adopted described technical scheme, the utility model, by integrally-built change, is keeping under the prerequisite of easel original function, has greatly saved easel and has packed up rear shared space, thereby be convenient to deposit and transport.
But we find in actual use, once fixing shelves, after long-term use, once wearing and tearing are arranged at bottom, will cause whole easel to put shakiness before the easel of this spline structure, need to again change fixing shelves, very trouble.Therefore we need to carry out to such easel base an adjustment.
Utility model content
The purpose of this utility model is to provide a kind of tripod firm banking for pillar easel, by changing understructure, even if make can also guarantee that easel is stable after long-term use.
In order to reach described object, the technical scheme that the utility model adopts is a kind of tripod firm banking for pillar easel, be arranged on backbone, backbone center is longitudinally provided with loose slot, in described loose slot, be connected with in the pillar easel that draws shell and drop-down shell, also be provided with L shaped feet, described L shaped feet top is movably connected in the loose slot of described backbone, in described loose slot, be also fixed with left foot and right crus of diaphragm, described left foot and right crus of diaphragm are comprised of the upper support bar being flexibly connected and lower support bar.
Preferably, described upper support bar and lower support bar are the one end that is wider than upper support bar and lower support bar flexible connection near one end of loose slot.The one end that so just can guarantee to be fixed on loose slot is more stable.
Preferably, described left foot and right crus of diaphragm are fixed in loose slot by bakelite screw.
Preferably, the upper support bar of described right crus of diaphragm is in the outside of the upper support bar of left foot, and the lower support bar of right crus of diaphragm is in the inner side of the lower support bar of left foot.The structure being staggered installation of like this makes on the pin of left and right stressed more even, and whole easel is more stable.
Preferably, described L shaped feet is formed by connecting by loose-leaf by two motion bars.Like this simple in structure, firm.
Owing to having adopted described technical scheme, the utility model, by integrally-built change, is keeping under the prerequisite of easel original function, has improved the degree of stability of easel bottom, and can adjust in the larger context the height of easel.Even because long-term use causes having some wearing and tearing, also can not have influence on the stability of whole support body.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is a kind of tripod firm banking main body schematic diagram for pillar easel of the utility model.
The specific embodiment
As shown in Figure 1, a kind of tripod firm banking for pillar easel of the utility model, be arranged on backbone 1, backbone 1 center is longitudinally provided with loose slot 2, in described loose slot 2, be connected with in the pillar easel that draws shell 3 and drop-down shell 4, be also provided with L shaped feet 5, described L shaped feet 5 tops are movably connected in the loose slot 2 of described backbone 1, in described loose slot 2, be also fixed with left foot and right crus of diaphragm, described left foot and right crus of diaphragm are comprised of the upper support bar 6 being flexibly connected and lower support bar 7.Described upper support bar 6 and lower support bar 7 are the one end that is wider than upper support bar 6 and lower support bar 7 flexible connections near one end of loose slot 2.Described left foot and right crus of diaphragm are fixed in loose slot 2 by bakelite screw 8.The upper support bar 6 of described right crus of diaphragm is in the outside of the upper support bar 6 of left foot, and the lower support bar 7 of right crus of diaphragm is in the inner side of the lower support bar 7 of left foot.Described L shaped feet 5 is formed by connecting by loose-leaf by two motion bars.
By such left and right pin, arrange, can more convenient adjustment height of drawing board.Because in prior art, drawing board draws shell 3 and 4 combinations of drop-down shell to fix from above.Once need to adjust height of drawing board, need to adjust the height that draws shell 3 and drop-down shell 4 simultaneously.And as long as adjust, in loose slot 2, fixedly the bakelite screw 8 of upper support bar 6 positions is just passable in the utility model.Like this can not only be at the whole height of drawing board of the enterprising step in the original basis of support body, and can guarantee that left and right pin does not affect the stability of whole easel yet after wearing and tearing to some extent after using certain time limit.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, the utility model can be on similar furniture, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
