Description

The spiral lift basketball stands

The utility model relates to a kind of basketball stands.

Employed ball-collecting rack mostly is fixed ball-collecting rack in the basketball movement at present, be that ball-collecting rack ring and ground level are always a fixed number, be broadly divided into two classes, one class is to require (the high 3.05M of being of ring) according to Basketball Match, and the ball-collecting rack of making is adopted in all kinds of Physical Education Teaching of university by primary school.The elevating function of employed fluid pressure type basketball stands mainly plays folding effect in the general stadiums, for formal competition, training, use.Because outdoor sports ground need not fold, it involves great expense (every pair reaches more than tens thousand of units) thereby is not suitable for outdoor sports ground and uses in addition.Another kind of is that the ring height that aims at kindergarten or this special age colony's manufacturing of primary grades is the fixed ball-collecting rack of 2 meters left and right sides not equal altitudes, and shortcoming is no height change, only is confined to the blue or green juvenile of child or part and uses.This fixed basketball stands only are suitable for because of whole height is fixing being grown up or teenager with certain physical qualification carries out basketball movement, and concerning most primary schools or the lower student in junior middle school, in the face of too high standard ball-collecting rack feels more unable to do what one wishes, and short excessively little ball-collecting rack is felt very unfulfilling, thereby has bigger limitation.

The purpose of this utility model provides a kind of spiral lift basketball stands, and it can satisfy the demand of different height personnel to the ring height by regulated at will ball-collecting rack height, and is simple in structure again, handsome in appearance, sturdy and durable, inexpensive.

For achieving the above object, the utility model comprises ring, backboard, backboard link, left and right sides support arm, crossbeam and support, it is characterized in that: support and form by base, vertical columns, slip column, casing, transmission mechanism, drag link mechanism, vertical columns is installed on the base, slip column upper end is connected with the casing that links to each other with crossbeam, the lower end is loaded in the vertical columns, transmission mechanism is installed in casing and the column, and the drag link mechanism upper end is connected with crossbeam, the lower end links to each other with base.Described transmission mechanism comprises screw axis, nut steady pin, nut, conical gear, zanjon radial ball bearing, thrust ball bearing, by the nut steady pin nut is fixed on the vertical columns, and nut and screw axis are formed screw pair; The active conical gear and the driven bevel gear that are installed in the casing are formed gear pair; The endoporus of thrust ball bearing cooperates with screw axis, the plane cooperates with the slip column, and the guiding lock sleeve is installed between slip column and vertical columns.Described drag link mechanism comprises sliding tie rod, locking member, can swing pull bar, sliding tie rod upper end and crossbeam afterbody by connecting pin be connected, the lower end with can swing the pull bar endoporus and match, sliding tie rod and can swing locking member is arranged between the pull bar can be swung pull bar and link to each other with base by linkage.The whole mechanical driving device of the utility model all is arranged among the support body column, and crossbeam, column are the single arm type design.

Operation principle: when the utility model is installed on basketball court, linked to each other with the court concrete pedestal by swell fixture by base, vertical columns is welded on the base.After installing basketball stands, unclamp the locking member in guiding lock sleeve and the drag link mechanism, rotate initiatively conical gear rotation and drive driven bevel gear and rotate, driven bevel gear drives screw axis by flat key and rotates, pass through screw pair, screw axis is done upper and lower motion simultaneously, drives the slip column by thrust ball bearing again and moves both vertically up and down, realizes the selection of basketball stands height.In this motion process, sliding tie rod slides can swinging in the pull bar.Simultaneously, can swing the angle generation respective change of pull bar and base, this variation realizes by hinge and hinge seat.After highly selected, lock guiding lock sleeve on the column and the locking member on the pull bar respectively, the rotational freedom of backboard is limited.Height does not change because of the latching characteristics of screw mechanism.

The utility model adopts the design of lift ball-collecting rack to solve preferably in the current basketball teaching influences the teenager can't reach ring by standard action shooting a difficult problem because of fixed ball-collecting rack, realized the dream that students " flies the body dunk shot ", for playing basketball, students in middle and primary schools provide convenience, the utility model has adopted current domestic popular single arm type design, whole mechanical driving device all is arranged among the support body column, modern design, handsome in appearance.Unique gear spindle gear is reasonable in design, hand-operated lifting, free and relaxed, simultaneously can be in design runlength (2.00m～3.05m) is the location arbitrarily, and the inside and outside court of this product chambers all can be used, and is practical, convenient.Utilize designed screw mechanism to have self-locking characteristics and special drawing and pulling type active pull rod and retaining mechanism, kept the highly stable of frame body, the backboard non-angular changes, and is safe and reliable during use.Its body and backboard all adopt high-quality shaped steel and fiberglass manufacturing, and be sturdy and durable, inexpensive.The utility model adult, child all are suitable for, and are the substitute products of fixed basketball stands.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
