Detailed description of the invention
As shown in Figure 1, the present embodiment comprise two be parallel to each other arrange for hang net 4 column 1, respectively with two root posts 1 leg 3 connected vertically, and two ends respectively with two legs 3 cross bar 2 connected vertically; Wherein cross bar 2 adjustable length, for regulating the distance between two columns 1 to control the tensioning degree of net 4; Described cross bar 2 is all vertical with two root posts 1, and is positioned at same plane, forms U-shaped; Described leg 3 is perpendicular to column 1 and cross bar 2 place plane.
As shown in figs 2-4, described leg 3 comprises connector 3-1, this connector is by the first port 3-2 for being connected with column 1 interference fits, the second port 3-3 for being connected with cross bar 2 interference fits, and coaxially arranged third connectivity mouth 3-4 and the 4th port 3-5 forms, four ports intersect at same point and are interconnected, wherein the first port 3-2, the second port 3-3 and third connectivity mouth 3-4 are arranged vertically (same, to be also be arranged vertically between two with the 4th port) between two, described third connectivity mouth 3-4 is connected one foot lever 3-6 with equal interference fits on the 4th port 3-5, this foot lever other end socket leg lock-bit cap 3-7, the first stretch cord 3-8 is connected with between two leg lock-bit cap 3-7, namely this first stretch cord one end is fixed on the leg lock-bit cap 3-7 of wherein one foot lever 3-6, the other end is successively coaxially through this foot lever 3-6, third connectivity mouth 3-4, after 4th port 3-5 and another root prop up foot lever 3-6, being fixed on another root props up on the leg lock-bit cap 3-7 of foot lever 3-6, thus by connector 3-1, two foot lever 3-6, two leg lock-bit cap 3-7 are connected.
As shown in Figure 5-Figure 7, described cross bar 2 comprises attacks female cylindric length adjustment head 2-1, these length adjustment head two ends respectively connect a hollow length adjustment bar 2-2(by screw thread and length adjustment head link has attacked external screw thread), the described length adjustment bar 2-2 other end is connected some hollow stem 2-4(length adjustment bars by cylindric adapter sleeve 2-3 and is all connected by adapter sleeve with between adjacent vacant core bar, between adjacent two hollow stems), the hollow stem 2-4 being positioned at end is connected with the second port 3-3 interference fits; Described adapter sleeve 2-3 and be interference fits between length adjustment bar 2-2, hollow stem 2-4.
The rotation direction of described length adjustment head 2-1 two ends screw thread is contrary, during use, only needs to rotate length adjustment head 2-1 and just can regulate distance between two columns 1, control the tensioning degree of net 4, to meet the regular requirement to net 4 tensioning degree of badminton.
As shown in Figure 8, Figure 9, in order to make adjacent two hollow stem 2-4 or length adjustment bar 2-2 equal with the length that adjacent vacant core bar 2-4 is socketed in adapter sleeve 2-3, to reach stable connection effect, the present embodiment will be processed into the annular ditch channel-shaped be inwardly recessed in the middle part of adapter sleeve 2-3.
As shown in Figure 10, Figure 11, described column 1 comprises some hollow stem 1-1, and for connecting the branch sleeve 1-2 of adjacent two hollow stem 1-1; The hollow stem 1-1 bottom being wherein positioned at bottom is connected with the first port 3-2 interference fits, be positioned at the hollow stem 1-1 top socket lock-bit connector 1-3 at top, lock-bit connector 1-3 wherein on a root post 1 is connected with the second stretch cord 1-4, this the second stretch cord free end is successively through the lock-bit connector 1-3 be connected to after this column, cross bar 2 and another root post on another column, thus whole rack is connected, utilize the tensioning function of the second stretch cord 1-4 self to make whole grid structure more stable simultaneously.
Each lock-bit connector 1-3 upper end outer surface is provided with some hooks for mounting or be ball-receiving net 4.In this example, described hook comprises downward opening first hook 5, and lays respectively at these first hook both sides and the opening up second hook 6 and the 3rd hook 7; Described second hook 6 and first links up with 5, and the 3rd links up with 7 and first and link up with the central angle that folded by 5, circular arc is corresponding and be 90 degree; Two first of laying respectively on two columns 1 link up with 5 back to layout, make suspension or dismantle net 4 simple and fast, ensure that rope sling not upwards slippage and the downward landing of net 4 both sides.
After finishing using, first net 4 is taken off, then hollow stem 1-1 is extracted folding in branch sleeve 1-2, hollow stem 2-4 extracts folding in adapter sleeve 2-3, length adjustment bar 2-2 extracts folding in adapter sleeve 2-3, length adjustment bar 2-2 screws out folding in length adjustment head 2-1, and the foot lever 3-6 to be connected with connector 3-1, hollow stem 2-4 and hollow stem 1-1 extracts folding, form folded state as shown in figure 12, overall volume is diminished, simultaneously because the contact that runs through of stretch cord makes each parts still be integrated, not easily lose arbitrary parts, and without the need to dismantling any parts, whole folding process is 1-2 minute consuming time only, convenient and swift, in addition, the length after whole rack folds and packs up is slightly less than the length of racket, can load in a sack, be convenient for carrying and move together with racket, net and shuttlecock.
The present embodiment uses simple to operate, quick, can in the vacant lot of community or garden, sandy beach, first-class place, meadow use, also can use in formal competition, conveniently can be folded into smaller size smaller after finishing using, be convenient for carrying movement.
