Description

A kind of long tooth adjusting rod lifting basketball stands

Technical field

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

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:

A kind of long tooth adjusting rod lifting basketball stands, comprise that there is fixed head the vertical rod that is fixed with on the base, vertical rod upper end, regulates ratch, backboard and basketry, also wrapping has a lower major axis to link to each other between two groups of draft links, have a cross tube to link to each other between two groups of upper pendulum bars, 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 fixing hole of described adjusting ratch and described lower major axis are slidingly matched; Described cross tube in self-locking tooth holder on the described adjusting ratch.

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.

As further improvement: 6 to 9 self-locking teeth are arranged on the described adjusting ratch.

The beneficial effects of the utility model are: in the time of adjusting the basketry height, only need the self-locking tooth of regulating on the ratch is broken away from cross tube, backboard and basketry are moved on to calibrated altitude, again the self-locking tooth on the adjusting ratch is held cross tube and just can.

Utilize when regulating ratch disengaging cross tube, 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 be controlled backboard and make up and down vertical oscillation, moves up and down with basketry.

Be slidingly matched in conjunction with the fixing hole 3 of regulating ratch and the lower major axis that is positioned on described two groups of draft links, self-locking tooth on regulating ratch) when holding in the palm the cross tube that is positioned 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 two trapezoidal replacements, it is second trapezoidal that the first trapezoidal and lower moving axis pin that namely descends that dead axle pin and upper dead axle pin and lower major axis and cross tube consist of and upper moving axis pin and lower major axis and cross tube consist 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:
