Description

Shuttlecock and soft-ball sports general network column holder

Technical field

The utility model relates to shuttlecock and soft-ball sports general network column holder.

Background technology

Standard badminton net post measures from ground, place, and net is high 155 centimetres, and soft-ball sports need net high by 175Centimetre, 6.1 meters of the doubles width in place in addition, the two is just the same for 11.88 meters of the length of doubles service line. At present indoor generalThe sports of training soft-ball are all on the basis of badminton grid frame, by increasing to meet the requirements of height. Training shuttlecock and softPower ball sports are different when ball, and the two is dismounting back and forth, very inconvenient. Increasing of the height of net, can make the overall center of gravity of rackRise, rack steadiness variation. The width of net has the span of 6.1 meters, middle not support in addition, and net weight is heavier, under centreHeavy more. If peacetime training does not have strict height control, that is to when match, often because after the height of net uprises, and ballDo not cross net, affect the performance of achievement. High-level net height requirement is the guarantee that athletes ' performance improves. The soft power of outdoor trainingBall sports are generally gathered materials on the spot, and both-end is tied up in the tree, or is fixed on pillar, but do not have in spacious place to rely onFixture, just can not train. Existing outdoor easy rack of playing badminton in addition, mostly on the ground of landing between two net postsAdd longitudinal pole of 6.1 meters of bar width, allow centre, Bu Huixiang place, net post lower end slide, but because pole length has 6.1 meters,Must be to connect the lengthening of more piece pole to form, the connection in the middle of their be combined with cumulative errors, allows it produce an outside supportPower is very limited. Also there is same situation in the easy rack of this shuttlecock, because net middle part does not have other support, by net certainlyBody gravity and the sinking that produces can not be eliminated completely by the degree of tension of bracing wire, and soft bracing wire does not have rigidity, in netBetween always have drop.

Summary of the invention

The purpose of this utility model is in order to overcome existing badminton grid frame and the uncurrent phenomenon of soft-ball sports rack,And the problem that as far as possible reduces of net middle part deflection, the utility model by the following technical solutions:

Middle flexible height bar for net post for increasing its intensity, adds triangle reinforcement on horizontal and vertical; Bracing wire is adoptedWith cable-stayed type, increase longitudinal pulling force, reduce the pressure in short transverse; In bracing wire, increase the adjuster that regulates tightness; At netMiddle sink to the most seriously locating, increase a bar height mark post, height mark post adopts binodal expansion link, allow highly reach 1.55 meters and1.75 meters (play badminton and all can use with soft-ball sports), to ensure the height in the middle of net, and minimizing is because netting twine self is heavyThe moment of measuring and produce, deflection can reduce 3/4ths in theory. The bilateral outside of net post adds two counterweight sand hills of providing for oneself, byTwo sand hill weight and the moment that produces, and the weight of netting twine and the moment that produces balances each other, and makes whole net post steadiness strong. FeatherBall and soft-ball sports general network column holder, comprise bracing wire, wire-drawing regulator, and middle flexible height bar, counterweight sand hill, longitudinally addsStrong muscle, longitudinally bottom bar, cross bar reinforcement, laterally bottom bar, metal threeway, height mark post.

The utlity model has following advantage: highly versatile, easy to carry, to install simply, the stability of rack is strong, net waterPingdu is good.

Detailed description of the invention:

Referring to Fig. 1, as shown in the figure, support comprises bracing wire 1, wire-drawing regulator 2, and middle flexible height bar 3, counterweight sand hill 4,Waling 5, longitudinally bottom bar 6, cross bar reinforcement 7, laterally bottom bar 8, metal threeway 9. Bracing wire 1 is fixed on longitudinal bottom bar 6,Net is through in bracing wire 1. Setting height(from bottom) mark post 10 in the middle of net, makes to net the middle height that can reach standard, can not sink.

Referring to Fig. 2, as shown in the figure, wire-drawing regulator 2 comprises left-hand thread screw rod 11, rotation guide block 12, right-handed thread screw 13.Wire-drawing regulator 2 two ends be bracing wire 1, when rotation guide block 12 is while rotating, bracing wire can be tightened up, and makes bracing wire well-pressed.

Referring to Fig. 3, as shown in the figure, height mark post 10 is propped net by the dop 14 on top, and it is off the net heavy can not allow, dop14 are fixed in the endoporus of little bar 16 by bolt 15, when the prefabricated through hole 20 on prefabricated through hole 17 and large bar 21 overlaps, highlyThe height of mark post 10 is 1.55 meters, when the prefabricated through hole 20 on prefabricated through hole 18 and large bar 21 overlaps, and the height of height mark post 10Be 1.75 meters, overcoat 19 is the sheathings that connect little bar 16 and large bar 21, play the guiding role, and lid 22 is protected the end of large bar 21Head.

Referring to Fig. 4, as shown in the figure, middle flexible height bar 3 upper ends are guiding blocks 23, and it covers on the little bar 24 of activityPortion, movable little bar 24 middle part cover outer locking connect decorates firmware 25, and the fixing internal locking firmware 26 of 24 times client links of movable little bar is alsoAnd be enclosed within large bar 29, the top cover outer locking of large bar 29 connects decorates firmware 25, the bottom of large bar 29 make a call to two orthogonalThrough hole 27 and 28, for connecting waling 5 and cross bar reinforcement 7, large bar 29 bottoms put metal threeway 9.

Referring to Fig. 5, as shown in the figure, Q2 is the weight of counterweight sand hill, and L2 is the distance of counterweight sand hill to middle flexible height barFrom. Upper figure is while thering is no intermediate altitude mark post, and Q1 is whole weight of throwing the net, and L1 is the width of half net, and the two amassing is wholeThe deadweight of net and the moment that produces; Figure below is while having intermediate altitude mark post, and Q3 is the weight of partly throwing the net, and its value is the half of Q1;L3 is the width of 1/4th net, and its value is the half of L1.

Therefore Q3*L3=1/2Q1*1/2L1=1/4 (Q1*L1)

The two long-pending be one of four parts of upper figure, so due to after middle height mark post adds, due to the weight of netThe moment producing can reduce 3/4ths, thereby the deflection producing can reduce 3/4ths, and the well-pressed degree of net can promote greatly.
