Abstract
The invention discloses an improved ball rack structure of reduced size.The improved ball rack structure comprises four supporting column bodies and eight connecting columns, wherein every two equal-length connecting columns form a group and are staggered and connected in a pivoted mode to form a connecting column group, and the equal-length connecting column groups are oppositely arranged and are connected to ejecting sleeve portions fixed on the four supporting column bodies or sliding sleeves slidably arranged on the four supporting column bodies in a pivoted mode.The bottom end of each connecting column is arranged on the corresponding independent sliding sleeve in a pivoted mode, so that the eight connecting columns are provided with the eight matched sliding sleeves for pivoted connection of the columns.Therefore, even if the eight connecting columns are different in length, an unfolded ball rack can be square or rectangular, the number of accommodated balls can be larger, and the best closing-up effect of complete closing up can be reached during closing up of the ball rack.
Description
Technical field
The present invention provides the technical field of a kind of ball-collecting rack, espespecially it technically provides a kind of and has the ball-collecting rack structural improvement reducing volume, it is able to a joint pin and coordinates a sliding sleeve, and such volume that reduces that must, when the joint pin Length discrepancy on adjacent two sides, remain to reach the best imitates able one.
Background technology
nullAs shown in Figure 1，For a kind of existing can folding reduce volume ball-collecting rack，Existing can folding reduce volume ball-collecting rack，Before it includes、Below、Left surface and right flank，It is respectively equipped with first to fourth cylinder 11、12、13、14，First to fourth cylinder 11、12、13、14 tops are fixed one first to fourth top cover portion 111 respectively、121、131、141，First top cover portion 111 is pivoted one end of one first joint pin 112 and one second joint pin 113，Second top cover portion 121 is pivoted one end of one the 3rd joint pin 122 and one the 4th joint pin 123，3rd top cover portion 131 is pivoted one end of one the 5th joint pin 132 and one the 6th joint pin 133，4th top cover portion 141 is pivoted one end of one the 7th joint pin 142 and one the 8th joint pin 143，Sheathed one first sliding sleeve 15 of sliding on first cylinder 11，Described first sliding sleeve 15 is pivoted the 3rd、8th joint pin 122、The other end of 143，Sheathed one second sliding sleeve 16 of sliding on second cylinder 12，Described second sliding sleeve 16 is pivoted second、Five joint pins 113、The other end of 132，Sheathed one the 3rd sliding sleeve 17 of sliding on 3rd cylinder 13，Described 3rd sliding sleeve 17 is pivoted the 4th、Seven joint pins 123、The other end of 142，Sheathed one the 4th sliding sleeve 18 of sliding on 4th cylinder 14，4th sliding sleeve 18 is pivoted first、Six joint pins 112、The other end of 133，First、Eight joint pins 112、143 stage casing pivot joints，Second、Three joint pins 113、122 stage casing pivot joints，4th、Five joint pins 123、132 stage casing pivot joints，6th、Seven joint pins 133、142 stage casing pivot joints，Accordingly，During expansion, sliding sleeve moves up，Make the distance between any two cylinders gradually remote，During gathering, sliding sleeve moves down，Make any two cylinders gradually close，But because two joint pins share a sliding sleeve，Shorter joint pin direction, wherein side is received extremely prescribe a time limit，The longer joint pin direction of another side cannot be drawn in again，Cause gathering poor effect，To be improved for its disappearance.
On the other hand, when existing joint pin is all expanded to required size, it is accomplished by living its Distance positioning, the unexpected situation drawn in voluntarily is avoided to occur, as shown in Figure 2, it is a kind of common turnover location bar 19, its turnover location bar 19 includes bipole body 191, 192 one end pivot joints, the one body of rod 191 one end is comparatively protruded and is provided with a positioning block 1911, the corresponding locating piece 1911 of another body of rod 192 is provided with locating slot 1921, such hands pressure bipole body 191, the locating piece 1911 of 192 snaps in the purpose that can reach location towards locating slot 1921, but the situations such as the relatively easy danger causing finger to crush of its structure, there is necessity of improvement in fact.
Another further aspect, known eight joint pins share four sliding sleeves, so when eight joint pins are all isometric, it is no problem to reach to fold completely, but its problem is that eight joint pins will be isometric, when comparing with the present invention under identical width, hence it is evident that the ball number that known ball-collecting rack can hold is just few a lot.
So, for the problem points existing for above-mentioned conventional construction, how developing the innovation structure of the more desirable practicality of one, real consumer is eagerly looked forward to, and is also target and the direction of relevant dealer palpus effort research and development breakthrough.
In view of this, inventor this in manufacturing development and the design experiences of being engaged in Related product for many years, for above-mentioned target, in detail after design and scrupulous assessment, eventually the present invention really having a practicality.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, a kind of ball-collecting rack structural improvement having and reducing volume is provided, it is able to a joint pin and coordinates a sliding sleeve, such must when the joint pin Length discrepancy on adjacent two sides, what remain to reach the best reduces volume effect, and enables the ball-collecting rack after expansion to hold more ball number.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of have the ball-collecting rack structural improvement reducing volume, including: number Body of pillar respectively first to fourth cylinder；Respectively first to fourth top cover portion of several top cover portions, first to fourth cylinder top described is fixed first to fourth top cover portion described respectively；Several the identical or different joint pin of length respectively the first to the 8th joint pins, first top cover portion is pivoted one end of the first joint pin and the second joint pin, second top cover portion is pivoted one end of the 3rd joint pin and the 4th joint pin, 3rd top cover portion is pivoted one end of the 5th joint pin and the 6th joint pin, 4th top cover portion is pivoted one end of the 7th joint pin and the 8th joint pin, the first, eight joint pin stage casing pivot joint, second and third joint pin stage casing pivot joint, fourth, fifth joint pin stage casing pivot joint, the six, the seven joint pin stage casing pivot joints；Sliding sheathed one first on first cylinder, five sliding sleeves, described first sliding sleeve is pivoted the other end of the 3rd joint pin, the other end of the 5th sliding sleeve pivot joint the 8th joint pin, sliding sheathed one second on second cylinder, six sliding sleeves, described second sliding sleeve is pivoted the other end of the second joint pin, the other end of the 6th sliding sleeve pivot joint five joint pin, sliding sheathed one the 3rd on 3rd cylinder, seven sliding sleeves, described 3rd sliding sleeve is pivoted the other end of the 4th joint pin, the other end of the 7th sliding sleeve pivot joint the 7th joint pin, sliding sheathed one the 4th on 4th cylinder, eight sliding sleeves, 4th sliding sleeve is pivoted the other end of the first joint pin, the other end of the 8th sliding sleeve pivot joint the 6th joint pin, with composition one ball-collecting rack.When ball-collecting rack launches, all sliding sleeves move up, and make every joint pin be extended, and the ball-collecting rack of expansion is that rectangle accommodation ball number is more, and when ball-collecting rack draws in, all sliding sleeves move separately down, make the joint pin of different length also can reach best gathering effect person.
In technique scheme, every two the isometric joint pin pivot joints of described ball-collecting rack are one group, and joint pin described in least one set is assembled into a turnover location bar, and described turnover location bar is provided with a clamping preventing jacket.
