Summary of the invention
The object of the present invention is to provide a kind of for people's particularly teenager's two-dimentional coordinated type basketball stands of shooting under backboard active state, fix for solving basketball stands backboard in prior art, its function singleness, can not play the problem of tempering person's development ability, judgement and the coordination ability.
Technical scheme of the present invention is:
A kind of two-dimentional coordinated type basketball stands, comprise backboard, also comprise:
Underframe, is divided into two-layer up and down;
Driving mechanism, is fixedly installed on described underframe lower floor;
Track, is fixedly installed on the upper strata of described underframe;
Guide thimble, is vertically arranged on described underframe by the roller coordinated with described track;
Crank connecting link, comprises first connecting rod and second connecting rod, described first connecting rod and second connecting rod hinged, the free end of described second connecting rod is fixedly installed on the output shaft of described driving mechanism, and described second connecting rod is vertical with the output shaft of described driving mechanism;
Column, is vertically arranged, and is set in described guide thimble, and the first end of described column is fixedly connected with described backboard, the second end of described column and the free end of described first connecting rod hinged.
Preferably, described driving mechanism comprises motor and speed reducer, and the free end of described second connecting rod is fixedly installed on the output shaft of described reductor.
Preferably, the height of described guide thimble is the 1/2-2/3 of described stem height.
Further, the internal diameter of described guide thimble 2mm-20mm larger than the external diameter of described column.
Further, the internal diameter of described guide thimble 4mm-10mm larger than the external diameter of described column.
Two-dimentional coordinated type basketball stands of the present invention, when driving mechanism operates, crank connecting link action, column can be made in the course of action of crank connecting link to move up and down, guide thimble can be made again to carry out straight reciprocating motion simultaneously, namely be achieved the reciprocal two dimension interlock of backboard by these two kinds of combinations of moving simultaneously.
When direction of shooting is in crank rod movement plane orthogonal, corresponding backboard is in linking up and down; When direction of shooting is in parallel with crank rod movement plane, corresponding backboard is upper and lower front and back linkage; If anon-normal is shot to backboard, backboard is just equivalent to three-dimensional linkage.
Beneficial effect of the present invention is:
To present invention achieves by static basket support to dynamic basket support even to the transformation of two dimension interlock basket support, be breakthrough and the leap of a conception of species.Make people backboard up and down or up and down before and after two dimension interlock or be equivalent to three-dimensional slowly dynamically lower shooting, the useful enjoyment of shooting activity can be increased, temper person's development ability, judgement and the coordination ability, be of value to physically and mentally healthy, be particularly advantageous in growing up healthy and sound and intelligence development of children.The present invention is a kind of physical training facility, and being again a kind of amusement and recreation device, is the developing to traditional basket ball holder function and development, is particularly suited for children and uses, for they add a kind of new enjoyment.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, two-dimentional coordinated type basketball stands of the present invention, comprise backboard 1 and underframe 7, underframe 7 is divided into two-layer up and down, lower floor's underframe 7 is fixedly installed motor and decelerator 5, upper strata underframe 7 is fixedly installed track 8.
Track 8 is vertically provided with guide thimble 2 by roller 6.Column 3 is set in guide thimble 2, and the height of guide thimble 2 is the 1/2-2/3 of column 3 height, the internal diameter 2mm-20mm larger than the external diameter of column 3 of guide thimble 2, preferably, and the internal diameter 4mm-10mm larger than the external diameter of column 3 of guide thimble 2.The top of column 3 is fixedly connected with backboard 1, and bottom and the crank connecting link 4 of column 3 are hinged, and crank connecting link 4 comprises first connecting rod 41 and second connecting rod 42, first connecting rod 41 and second connecting rod 42 hinged, free end and the column 3 of first connecting rod 41 are hinged.
The free end of second connecting rod 42 is fixedly connected with the output shaft of reductor 5, and second connecting rod 42 is vertical with the output shaft of reductor 5.
Two-dimentional coordinated type basketball stands of the present invention, when decelerator 5 operates, crank connecting link 4 action, column 3 can be made in the course of action of crank connecting link 4 to move up and down, guide thimble 2 can be made again to carry out straight reciprocating motion simultaneously, namely be achieved the reciprocal two dimension interlock of backboard 1 by these two kinds of combinations of moving simultaneously.
