The content of the invention
It is an object of the invention to provide the two dimension that a kind of confession people particularly teenager shoots under backboard active state
Coordinated type basketball stands, fix, its unitary function, it is impossible to play exercise person's development energy to solve basketball stands backboard in the prior art
The problem of power, judgement and the coordination ability.
The technical scheme is that:
A kind of two-dimentional coordinated type basketball stands, including backboard, also include:
Underframe, is divided into upper and lower two-layer;
Drive mechanism, is fixedly installed on the underframe lower floor;
Track, is fixedly installed on the upper strata of the underframe;
Guide thimble, is vertically arranged on the underframe by the roller coordinated with the track;
Crank connecting link, including first connecting rod and second connecting rod, the first connecting rod and second connecting rod are hinged, and described second connects
The free end of bar is fixedly installed on the output shaft of the drive mechanism, the output shaft of the second connecting rod and the drive mechanism
Vertically;
Column, is vertically arranged, and is set in the guide thimble, and the first end of the column is fixed with the backboard and connected
Connect, the second end of the column is hinged with the free end of the first connecting rod.
Preferably, the drive mechanism includes motor and speed reducer, and the free end of the second connecting rod is fixedly installed on institute
State on the output shaft of reductor.
Preferably, the height of the guide thimble is the 1/2-2/3 of the stem height.
Further, the internal diameter of guide thimble 2mm-20mm bigger than the external diameter of the column.
Further, the internal diameter of guide thimble 4mm-10mm bigger than the external diameter of the column.
Two-dimentional coordinated type basketball stands of the invention, when drive mechanism is operated, crank connecting link action, the action of crank connecting link
During can move up and down column, while can make the guide thimble carry out straight reciprocating motion again, by both same lucks
Dynamic combination realizes the reciprocal two dimension linkage of backboard.
When direction of shooting is in vertical with crank rod movement plane, corresponding backboard is in link up and down;When
When shooting direction is in parallel with crank rod movement plane, corresponding backboard is in upper and lower front and back linkage;If anon-normal is to basket
Plate is shot, and backboard is equivalent to three-dimensional linkage.
Beneficial effects of the present invention are:
The present invention is realized by static basket support to dynamic basket support even to the transformation of two dimension linkage basket support, is a conception of species
Break through and leap.Make people backboard up and down or up and down before and after two dimension linkage or equivalent to three-dimensional slowly dynamic under throw
Basket, can increase the beneficial enjoyment of shooting activity, temper person's development ability, judgement and the coordination ability, be beneficial to body and mind
Health, is particularly advantageous in growing up healthy and sound and intelligence development for children.The present invention is both a kind of physical training facility, is again one
Amusement and recreation device is planted, is developing and development to traditional basket ball holder function, used particularly suitable for children, for they increase
A kind of new enjoyment.
Embodiment 1
As shown in figure 1, two-dimentional coordinated type basketball stands of the invention, including backboard 1 and underframe 7,7 points of underframe is upper and lower two
Layer, is fixedly installed motor and decelerator 5 on lower floor's underframe 7, track 8 is fixedly installed on upper strata underframe 7.
Guide thimble 2 is vertically arranged with by roller 6 on track 8.Column 3 is set in guide thimble 2, guide thimble 2
Height for the height of column 3 1/2-2/3, the internal diameter 2mm-20mm bigger than the external diameter of column 3 of guide thimble 2, it is preferred that be oriented to
The internal diameter of sleeve pipe 2 4mm-10mm bigger than the external diameter of column 3.The top of column 3 is fixedly connected backboard 1, the bottom of column 3 and crank
Connecting rod 4 is hinged, and crank connecting link 4 includes first connecting rod 41 and second connecting rod 42, and first connecting rod 41 and second connecting rod 42 are hinged, and first
The free end of connecting rod 41 is hinged with column 3.
The free end of second connecting rod 42 is fixedly connected with the output shaft of reductor 5, and second connecting rod 42 is defeated with reductor 5
Shaft is vertical.
Two-dimentional coordinated type basketball stands of the invention, when decelerator 5 is operated, crank connecting link 4 is acted, crank connecting link 4 it is dynamic
During work column 3 can move up and down, while the guide thimble 2 is carried out straight reciprocating motion again, it is same by both
The combination of Shi Yundong realizes the reciprocal two dimension linkage of backboard 1.
