Abstract

A lifting basketball stand with teeth arranged on the lower portion of an upper rod comprise a base seat, a stand rod is fixed on the base seat, a fixed plate is arranged at the upper end of the stand rod, and the lifting basketball stand further comprise two groups of lower swing rods, an adjusting cross rod, two groups of upper swing rods, a backboard and a basket. Two groups of lower fixed support seats and two groups of upper fixed support seats are respectively arranged on the front side of the fixed plate. Two groups of lower movable support seats and two groups of upper movable support seats are respectively arranged on the back side of the backboard. The lower fixed holes of the lower swing rods are hinged with the lower fixed support seats through lower fixed shaft pins. The lower movable holes of the lower swing rods are hinged with the lower movable support seats through lower movable shaft pins. The upper fixed holes of the upper swing rods are hinged with the upper fixed support seats through upper fixed shaft pins. The upper movable holes of the upper swing rods are hinged with the upper movable support seats through upper movable shaft pins. Two ends of the adjusting cross rod are connected two foot adjusting rods. The fixed holes of the two foot adjusting holes are hinged with the lower fixed shaft pins. The adjusting cross rod supports the upper rod tooth grooves of the two groups of swing rods at the same time. When the height of the basket needs to be adjusted, the adjusting cross rod simply needs to be separated from the upper rod tooth grooves, the basket is moved to a needed height, and the adjusting cross rod supports the upper rod tooth grooves.

Description

Long tooth lifting basketball stands under a kind of upper boom

Technical field

The utility model belongs to sports goods, is specifically related to long tooth lifting basketball stands under a kind of upper boom.

Background technology

Basketball is the sports item that liked by people, popularity rate is higher, arranges but most basketball stands all are requirements according to the regulation game standard, and it highly all is changeless, the calibrated altitude that basketry is liftoff is 3.05 meters, and the men and women is the same height.Very unfair for the not high crowd of individuality like this, especially unfair to the woman, can't make the graceful stimulation actions such as the aerial dunk shot of picture, affect especially the vast minor of middle and primary schools to interest and the enjoyment of basketball movement, be difficult to satisfy extensive crowd's motion requirement.

Summary of the invention

The purpose of this utility model provides a kind of Liftable basketball stands that can convenient adjustment differing heights.To achieve these goals, the utility model adopts following technical solution:

Long tooth lifting basketball stands under a kind of upper boom, comprise that there is fixed head the vertical rod that is fixed with on the base, vertical rod upper end, also comprise two groups of draft links, regulate cross bar, two groups of upper pendulum bars and backboard and basketry, as improvement: described fixed head front has respectively decides under two groups to decide bearing on bearing and two groups; There is respectively under two groups moving bearing on moving bearing and two groups at the described backboard back side; The lower fixed point hole of described draft link and describedly decide to have between the bearing lower dead axle pin hinged down; There is lower moving axis pin hinged between lower moving some hole of described draft link and the described lower moving bearing; The upper fixed point hole of described upper pendulum bar and describedly upward decide to have between the bearing upper dead axle pin hinged; There is upper moving axis pin hinged between upper moving some hole of described upper pendulum bar and the described moving bearing; The described adjusting cross bar two ends bipod adjusting rod of ining succession; The fixing hole of described bipod adjusting rod and described lower dead axle pin are hinged; Described adjusting cross bar is holding in the palm the upper boom teeth groove on described two groups of upper pendulum bars simultaneously.

As further improvement: the horizontal projected area of described base is between 1 square metre to 3 square metres; The sectional area of described vertical rod is between 20 square centimeters to 40 square centimeters; Distance is between 1.2 meters to 1.6 meters between described lower fixed point hole and the described lower moving some hole; Distance is between 1.2 meters to 1.6 meters between described upper fixed point hole and the described moving some hole; Describedly decide bearing and describedly upward decide between the bearing distance between 0.6 meter to 0.8 meter down; Distance is between 0.6 meter to 0.8 meter between described lower moving bearing and the described moving bearing.

The beneficial effects of the utility model are: in the time of adjusting the basketry height, only need to break away from the upper boom teeth groove regulating cross bar, basketry is moved on to desired height, again the adjusting support for cross bar is lived in the bar teeth groove and just can.

Utilize the movable parallelogram of the four-point articulated formation of lower dead axle pin, lower moving axis pin, upper dead axle pin and upper moving axis pin, can control backboard and make up and down vertical oscillation, move up and down with basketry.

Fixing hole and described lower dead axle pin in conjunction with the bipod adjusting rod are hinged, when regulating cross bar and holding in the palm simultaneously upper boom teeth groove on described two groups of upper pendulum bars, the static parallelogram of the four-point articulated formation of lower dead axle pin, lower moving axis pin, upper dead axle pin and upper moving axis pin is by triangle and trapezoidal the replacement: namely descend dead axle pin and upper dead axle pin and regulate trapezoidal that upper boom teeth groove that the triangle that the upper boom teeth groove consisted of that cross bar is positioned at and lower moving axis pin and upper moving axis pin and lower dead axle pin and adjusting cross bar be positioned at is consisted of, no longer displacement.

Be implemented in the height of controlling backboard and basketry in sizable scope by easy operation, guarantee simultaneously backboard all the time perpendicular to ground, thereby realize allowing more crowd experience basketball enjoyment.The utility model is novel, manufacturing is simple, simple operation, possesses popularizing value.

The utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
