The technical solution adopted for the present invention to solve the technical problems is: in hollow main rod, traditional not main part of Liftable basketball stands (is comprised to backboard, the backboard pull bar, basketball rim, the basketball stands semi-girder, the sub-fraction mobile jib be connected with semi-girder and with the adpting flange of screw mandrel (if adopt the method for directly welding do not need this adpting flange), and the support bar of basketball stands semi-girder---certainly, there are the basketball stands of some design types not need the support bar of this basketball stands semi-girder just can realize the stable of basketball stands, so do not needed the support bar of this basketball stands semi-girder) with a rhizoid bar, by the head flanges (or iron plate) of screw mandrel,---its profile and size are so that himself can be as the criterion with the cylinder inner surface laminating of hollow main rod---adopts bolt to fix or direct mode of welding, connection fastened to each other is (if not homemade screw mandrel, also need to determine whether to increase in addition a homemade adpting flange (or iron plate) according to the pattern of the head flanges of different screw mandrel products, so that screw mandrel can be fitted with the cylinder inner surface of hollow main rod with traditional not adpting flange of the main part of Liftable basketball stands (or iron plate)), the lifting of screw mandrel is by some corresponding transmission system drives, as two bevel gear transmission systems, Worm Wheel System system (optionally can directly adopt utilize that the Worm Wheel System system manufactures Worm gear feed screw lift product---the selection of Worm gear feed screw lift model is determined flexibly by actual Liftable basketball stands production requirement situation, generally, can select SWL series, structural shape l type, assembling pattern A type, screw mandrel head pattern II type, the Worm gear feed screw lift that the screw mandrel protective cover is Rotaryproof), etc., screw mandrel and above-mentioned transmission system by triangle coarse thread (because it has good self-locking property and rising or falling speed) be connected to each other (lifting of screw mandrel is also directly driven by these triangle coarse threads---apparent, ridge is thicker, and the rising or falling speed of screw mandrel is larger, otherwise anti-), transmission system is by the manual shaking wheel that is positioned at the hollow main rod outside be fixedly linked with it or electric rotary device drives, above-mentioned transmission system by bearing and bearing holder (housing, cover), be fixedly mounted on the inner surface of hollow main rod (as the inner surface that can adopt bearing holder (housing, cover) and hollow main rod directly welding realize fixed installation), baseplane being as the criterion of height on same level or slightly under the bottom surface of (now screw mandrel can't continue to descend) screw mandrel and hollow main rod when its installation site drops to its minimum altitude apart from the height of baseplane under hollow main rod with screw mandrel, in addition, at next-door neighbour's tip position of above-mentioned transmission system, an insulation blocking dividing plate is installed, for stop the head flanges (or iron plate) of screw mandrel when screw mandrel descends, avoiding its to oppress that worm gear makes it can't normal rotation, hollow main rod is fixedly mounted on the basketball stands base.
For example, when adopting two bevel gear transmission systems to go to drive the lifting of screw mandrel, small one and large one two bevel gears are passed through to the engaged connection of teeth, large umbrella gear is arranged on the top (purpose is to increase gearratio) of small umbrella gear, two bevel gears are arranged on respectively in bearing and bearing holder (housing, cover) separately, and the bearing holder (housing, cover) of two bevel gears all is fixedly connected with the inner surface of hollow main rod by the mode of direct welding; Superposed large umbrella gear hole is fixedly connected with the arm that connects that manual shaking wheel or electric rotary equipment stretch into hollow main rod by the mode of direct welding, the small umbrella gear hole that is positioned at bottom is connected to each other by triangle coarse thread and screw mandrel, and drives the lifting of screw mandrel by the triangle coarse thread; Simultaneously, next-door neighbour's tip position at superposed large umbrella gear is installed an insulation blocking dividing plate, for stop the head flanges (or iron plate) of screw mandrel when screw mandrel descends, avoiding its compressing large umbrella gear to make it can't normal rotation---and the purpose of size both can realize that isolation protection large umbrella gear is not oppressed by screw mandrel head flanges (or iron plate) when screw mandrel drops to certain altitude of insulation blocking dividing plate can not hinder again the normal oscilaltion of screw mandrel to be as the criterion; The parameters of the modulus of large and small bevel gear, gear ratio and small umbrella gear aperture (being the screw mandrel diameter) and wire rod thread, etc. parameter determine that take maximum gearratio, screw mandrel rising or falling speed and the screw mandrel heavy burden rising limiting altitude of assurance under the requirement of certain hollow main rod lateral dimension upper limit is principle, according to the requirement of different concrete conditions, adopt the method for experiment to determine.In like manner, when adopting the Worm Wheel System system to go to drive the lifting of screw mandrel, the worm and gear of engaged connection is arranged on respectively in bearing and bearing holder (housing, cover) separately, two bearing holder (housing, cover)s all are fixedly connected with the inner surface of hollow main rod by the mode of direct welding; Worm wheel aperture is connected to each other by these triangle coarse threads and screw mandrel, and drives the lifting of screw mandrel by these triangle coarse threads, and worm screw connects arm by fastened to each other connection of mode of directly welding with manual shaking wheel or electric rotary equipment; Simultaneously; next-door neighbour's tip position at the worm gear in top is slightly installed an insulation blocking dividing plate; for stop the head flanges (or iron plate) of screw mandrel when screw mandrel descends; avoiding its compressing worm gear to make it can't normal rotation---and the purpose of size both can realize that isolation protection large umbrella gear is not oppressed by screw mandrel head flanges (or iron plate) when screw mandrel drops to certain altitude of insulation blocking dividing plate can not hinder again the normal oscilaltion of screw mandrel to be as the criterion.When the transmission system that adopts other types goes to drive the lifting of screw mandrel, by that analogy.Be no matter adopt two bevel gear transmission systems or adopt Worm Wheel System system or the transmission system of other types to go to drive the lifting of screw mandrel, the fineness of triangle thread tooth that can be by control connection transmission system and screw mandrel is controlled the oscilaltion speed of screw mandrel; It should be noted that the adpting flange (or iron plate) that must guarantee all the time the screw mandrel head is parallel with the baseplane up and down of hollow main rod simultaneously.
Simultaneously, the cylinder top of hollow main rod cuts out an elongated square part over against the part of basketball rim, so that traditional not main part of Liftable basketball stands can therefrom freely be walked lifting up and down, when by the size of cutouts, with tradition, the main part of Liftable basketball stands is not therefrom walked lifting, both can fit---and purpose is to prevent the rotation of being forced to property of screw mandrel, and stop that it continues to rise after can making traditional not basketball rim of the main part of Liftable basketball stands rise to smoothly its maximum height (now basketball rim is 3.05 meters that international standard is formulated apart from ground level), simultaneously also can make it to drop to its minimum altitude (now the head flanges of screw mandrel (or iron plate) be subject to the insulation blocking dividing plate stop can't continue to descend) be as the criterion, and the principle that the part that following does not need to cut out cuts out scarcely is (to give full play to the isolation of hollow main rod outer surface to its internal components, protective effect).In addition, the upper basal surface of hollow main rod can according to tradition not the different types of the main part of the Liftable basketball stands support bar etc. of basketball stands semi-girder (as have or not) flexibly selection whether to cut out a corresponding part so that tradition not the main part of Liftable basketball stands can therefrom pass through, freely stretch out retraction, if select to cut out a part so that traditional not main part of Liftable basketball stands can therefrom be passed, freely stretch out retraction, by the shape of cutouts and size with tradition not the main part of Liftable basketball stands therefrom both can fit and are as the criterion when stretching out retraction, on mobile jib basal surface remaining not by cutouts for after when tradition, the basketball rim of the main part of Liftable basketball stands does not reach its maximum height apart from ground (be international standard formulate 3.05 meters) by stop tradition not the coupling part of main part and the screw mandrel head flanges (or iron plate) of Liftable basketball stands to stop its continuation rising, the part that the upper basal surface of this hollow main rod is cut out connects together with the part that damaged surface is cut out, and in general width is the same, all equal the radial width (purpose be also allow tradition the main part of Liftable basketball stands can be in wherein freely walking up and down lifting) of basketball stands semi-girder, meanwhile, the profile of hollow main rod should be elected as square---certainly, can make the principle of the cylinder inner surface laminating of himself and hollow main rod according to the profile of the head flanges (or iron plate) of screw mandrel and size, now the head flanges of screw mandrel (or iron plate) also will for square (purpose be prevent when the tradition not the main part of Liftable basketball stands stretch out being forced to property of screw mandrel rotation after basal surface on mobile jib, if certainly for security needs, the mobile jib of basketball stands is required to be circle, can weld the last layer round jacket in the outside of this square hollow main rod).The height of hollow main rod with can make tradition not the basketball rim of the main part of Liftable basketball stands rise smoothly and drop to its maximum height and minimum altitude, and do not waste and make material (being the not unnecessary making of unwanted part) and be as the criterion.The profile of hollow main rod (can for circular, square or other), make material (can be iron or other hard class material) and lateral dimension size (the whole lateral dimension size of main transmission system is determined) and bottom surface is totally-enclosed or Full-open (being generally Full-open), and near the damaged surface elongated projected square part whether cut out at hollow main rod is indicated the indicator graduation lines of basketball rim apart from ground level, and corresponding indicating device (or method) of installation (or employing), etc., can select flexibly to determine according to different concrete conditions.The base of this kind of Liftable basketball stands can be both fixed basketball stands base, can be also portable basketball stands base, according to different situations, selected flexibly.Simultaneously, all in this kind of Liftable basketball stands have irony device (or device of other material class of easily getting rusty a) part that contacts with each other and need to do relative motion, and all it carried out to antirust, lubricated; And can, according to the requirement of different concrete conditions, select flexibly to determine whether the device of being convenient to add lubricant is installed on this kind of Liftable basketball stands.
Like this, the user only need use the manual shaking wheel be fixedly connected with transmission system or the electric rotary equipment that is positioned at the hollow main rod outside, utilize the self-locking property of the triangle coarse thread of screw mandrel, by lifting and fixing screw mandrel, carry out the not main part of Liftable basketball stands of lifting and unchangable traditions, thereby realized the basketball rim free adjustment is fixed on the purpose of the arbitrary height between its maximum height apart from ground (being 3.05 meters that international standard is formulated) and minimum altitude (now screw mandrel can't continue to descend), that is to say, realized the purpose of free lifting basketball stands between basketball rim is apart from the maximum height on ground and minimum altitude.
Special instruction, definite method of the maximum S of screw mandrel effective travel (mean can effectively lifting tradition not the stroke of the main part of Liftable basketball stands) is as described below.As accompanying drawing 1, shown in 5, if the height of transmission system main part (comprising the insulation blocking dividing plate) is h1, screw mandrel bottom can not lifting part (unthreaded portion) height, when screw mandrel drops to its minimum altitude (be screw mandrel can't continue descend), the screw mandrel bottom surface is apart from the height of baseplane under hollow main rod (if both on same level its value is 0), the hollow main rod bottom surface (does not generally need, being no this item) height and the height sum of basketball stands base be h2, the height of the adpting flange of screw mandrel head (or iron plate) and tradition not the height of the adpting flange of the main part of Liftable basketball stands (when adopting while directly being welded to connect, just not having needed this adpting flange) (when adopting while directly being welded to connect, its value is 0) sum is h3, basketball rim apart from tradition not the height of the De Shang baseplane, coupling part of the head flanges (or iron plate) of the main part of Liftable basketball stands and screw mandrel be h4, h1+h2+h3+h4+2S=3.05 (unit be rice), be S=(3.05-h1-h2-h3-h4)/2 (unit is rice).In actual applications, when the screw mandrel effective travel is got this maximum S, basketball stands can drop to the minimum of a value of minimum altitude, and now basketball rim is (3.05-S) (unit is rice) apart from the height on ground, as shown in accompanying drawing 2,6; When the minimum altitude that basketball stands are descended is less demanding, the value of screw mandrel effective travel can be less than this maximum S, the minimum altitude that now basketball rim can descend is greater than its minimum of a value (3.05-S) (unit is rice)---and apparent, because the maximum height that basketball rim can rise is (is international standard formulate 3.05 meters) of fixing, so 2 times of the difference that the difference of two kinds of minimum altitudes is the minimum values of two kinds of screw mandrel effective travels.
