Abstract
The invention provides a bar hurdle base gear-shifting method and a bar hurdle base gear-shifting device. The bar hurdle base gear-shifting device is composed of a stand column, a base and bent grooves, and is characterized in that the stand column is fixedly connected wit the base, a bent groove assembly is arranged inside the base, and one ends of the bent grooves are movably connected to one end, close to the stand column, of the base; the specification of the bent grooves corresponds to each height specification of the bar hurdle, a circle is drawn by taking the height as the radius, partial fan-shaped arc edge is cut from the circle, and the arc edge is taken as the radian of the bent grooves; the bent groove assembly is the assembly of the plurality of bent grooves with the specification corresponding to the height specifications of different bar hurdles.
Description
Technical field：The present invention relates to a kind of sports equipment, and in particular to the control method of buffer-type hurdles rack.
Background technology：Buffer-type hurdles rack forward swing buffering course, because hurdle its swinging track of height of different gears is also different, be
Hurdle frame height is set not decline because of forward swing, it is necessary to configuration base lifting arc corresponding with the height hurdle frame.There is presently no one kind
The technology of correspondence lifting arc can be changed for the high gearshift in hurdle of different gears, advantage：Parts are saved, simplifies hurdle frame knot
Structure, outward appearance is more succinct.
The content of the invention
As shown in figure 1, the present invention is by column 1, base curved groove 2, the part of adjuster three composition, its central post 1 is curved with base
Groove 2 is fixedly connected, and base curved groove 2 is the set of two pieces and the differently curved radian curved groove of the above, and curved groove one end is movably connected on bottom
One end of nearly column is seated against, the other end is by screw connection adjuster, wherein connecting first curved groove and first without iron plate screw 3
Individual circular hole, short iron plate screw 4 connects second curved groove and short elongated hole, and long iron plate screw 5 connects the 3rd curved groove and most long
Elongated hole.Base curved groove slips down to operating position and blocks by the dop 8 and spring 9 control curved groove of adjuster, so as to complete gearshift
Work.
Curved groove is each height specification of correspondence hurdle frame, and with a part of fan-shaped arc that this highly draws circle as radius curved groove is equal to
Camber.Curved groove set is the set of the highly corresponding curved groove of various hurdle framves.
Description of the drawings
Fig. 1 is hurdle frame structure composition figure.
1 column, 2 base curved grooves, 3 without iron plate screw, 4 short iron plate screws, 5 long iron plate screws, 6 nuts, 7 adjuster gear iron
Block, 8 dops, 9 springs.
Specific embodiment
As shown in figure 1, column is a pipe, base curved groove is two pieces and the differently curved radian metal derby of the above, and base is curved
Groove one end is connected with column tube bottom, and one end is connected with adjuster, adjuster by the right angle screw for welding different length iron plate, one
Block is by hollow out elongated hole metallic plate, dop, spring, nut composition.
Claims (2)
1. by column, base, curved groove is constituted a kind of method and device of hurdles rack base gearshift described in, it is characterized by：Column with
Base is fixedly connected, and chassis interior includes curved groove set, and curved groove one end is movably connected on base near one end of column.
2. curved groove as claimed in claim 1, it is characterized by correspondence hurdle frame each height specification, is highly drawn with this as radius
Individual circle, from the circle partial sector arc side is intercepted, and using the arc side as the radian of curved groove, curved groove set is and different hurdle framves height
The set of the corresponding multiple curved grooves of specification.
