The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
With reference to Fig. 1, a kind of bracing frame 100 described in the present embodiment comprises a base 1, be arranged on a support bar 2 on base 1, be set in actively the sleeve 3 on support bar 2, the installing plate 4 being fixedly connected with sleeve 3, be connected to some supports 5 on installing plate 4 and for sleeve 3 being positioned at least one locating part 6 in support bar 2 precalculated positions actively.Described locating part 6 interts in sleeve 3 and support bar 2.
Some universal wheels 10 are installed on described base 1.This universal wheel 10 can be the existing universal wheel 10 with self-locking device.As shown in Fig. 1 or Fig. 3, universal wheel described in the present embodiment 10 is four.Universal wheel 10 is installed on base 1 and can be conveniently promoted bracing frame 100 slips, the labour intensity while alleviating carrying.Because this universal wheel 10 is with self-locking device, can conveniently bracing frame 100 be positioned to precalculated position.
In conjunction with reference to Fig. 3, described support bar 2 is cylindrical, offers some the first spliced eyes 20 on this support bar 2.Described the first spliced eye 20 can be between two and coaxially arranges.Described locating part 6 can intert in support bar 2 by this first spliced eye 20.Preferably, the two ends up and down of described support bar 2 offer respectively described the first spliced eye 20; Be appreciated that the first spliced eye 20 can be opened in the optional position of support bar 2.In order to alleviate bracing frame 100 overall weight, these support bar 2 inner hollow.Described the first spliced eye 20 all with support bar 2 internal communication.The two ends up and down of this support bar 2 respectively offer four the first spliced eyes 20.Particularly, wherein two first spliced eyes 20 of these support bar 2 upper ends coaxially arrange, and two other also coaxially arranges; In like manner, wherein two first spliced eyes 20 of support bar 2 lower ends coaxially arrange, and two other also coaxially arranges.Each locating part 6 can be plugged in two coaxial the first spliced eyes 20 that arrange simultaneously.The first spliced eye 20 of support bar 2 lower ends, except the effect for fixed muffle 3, can also, for taking in locating part 6, prevent locating part 6 loss.
With reference to Fig. 2, on described sleeve 3, offer two the second spliced eyes 30, these two the second spliced eyes 30 coaxially arrange.The lower edge of described sleeve 3 offers two grooves 31, and these two grooves, 31 alignment arrange.Line between two grooves 31 is mutually vertical with the line between two the second spliced eyes 30.When each second spliced eye 30 is during respectively with first spliced eye 20 co-axially align, each groove 31 also aligns with first spliced eye 20 respectively.Can pass through a locating part 6 to pass the first spliced eye 20 and the second spliced eye 30, and the locating part 6 of also pegging graft in the first spliced eye 20 and groove 31, thereby realize the precalculated position that sleeve 3 is positioned to support bar 2.
The quantity of support described in the present embodiment 5 can be six.This support 5 is for removably connecting with ball-collecting net (not shown).One end of each support 5 is hinged or be articulated on installing plate 4 by drive-connecting shaft.Each support 5 can rotate on installing plate 4, sleeve 3 can be positioned to the top of support bar 2, and support 5 is scattered, as shown in Figure 1 when using.When taking in, sleeve 3 can be positioned to the bottom of support bar 2, and support 5 is drawn in, as shown in Figure 3, reduce the space taking.This support 5 bends forward away from one end of installing plate 4.
The quantity of locating part described in the present embodiment 6 is two, and this locating part 6 can be screw, and what make that sleeve 3 can be more firm is positioned on support bar 2.When this locating part 6 is installed, can be by turn locating part 6 through the first spliced eye 20 and the second spliced eye 30.
As preferred embodiment, in conjunction with reference to Fig. 4, fixing on described installing plate 4 some limited blocks 41 are installed.Described support 5 is in opened condition time, and an end and the limited block 41 of this support 5 offset.Described limited block 41, for the scope of opening of limit bracket 5, prevents that support 5 from rotating arbitrarily.
As preferred embodiment, a cover plate (not shown) is also installed on described installing plate 4.On the dual-side of this installing plate 4, convex with respectively a folded walls 42, in each folded walls 42, offer at least one screw 420.Described folded walls 42 can be connected in cover plate, and folded walls 42 and cover plate is fixed by screw at screw 420 places.Described folded walls 42 is one-body molded with installing plate 4.
In sum, bracing frame 100 of the present utility model is positioned at sleeve 3 by locating part 6 precalculated position of support bar 2, installing plate 4 is fixed on sleeve 3, and support 5 is arranged on installing plate 4 actively, can determine by adjusting the position of sleeve 3 on support bar 2 height of installing plate 4 and support 5.Thereby realize the height of adjusting pole 5.And sleeve 3 can be positioned to the bottom of support bar 2 when taking in, reduce the whole height of bracing frame 100, minimizing takes up room, and improve the security while taking in.Because support 5 is arranged on installing plate 4 actively, during use, support 5 can be scattered in addition, improve the area while collecting ball, while taking in, support 5 be drawn in, reduce the accommodation space of bracing frame 100.
The utility model also provides a kind of table tennis ball collecting ball device, comprises a bracing frame 100 and the ball-collecting net (not shown) removably connecting with bracing frame 100.Support frame as described above 100 is above-described bracing frame 100.When using, sleeve 3 is positioned to the top of support bar 2, and support 5 is scattered, then ball-collecting net is arranged on support 5.When taking in, ball-collecting net is disassembled from support 5, can to ball-collecting net, carry out folding storage separately.Because support 5 one end away from installing plate 4 bends forward.After making support 5 scatter and ball-collecting net being arranged on support 5, ball-collecting net is net bag-shaped, more convenient table tennis is drawn in.The place ahead described in the present embodiment refers to the side that table tennis ball collecting ball device enters ball-collecting net for table tennis.
Table tennis ball collecting ball device of the present utility model, by ball-collecting net is arranged on support frame as described above 100, more convenient while making this table tennis ball collecting ball device carrying, the space that while taking in, this device takies is little, this device can also be toppled over and is prevented, avoids causing danger.This ball-collecting net can be installed predetermined height as required in addition, so the practicality of this table tennis ball collecting ball device is good.
