Detailed description of the invention
As shown in Fig. 1 ~ 4, this utility model is mainly made up of parts such as underframe 1, front column 2, rear column 3, telescopic advance lever 4, transverse arm 5, backboard 6 and basketrys.
Underframe 1 is welded by some hack levers are fixing, is used for supporting whole ball-collecting rack, is provided with counter weight device at the rear portion of underframe 1, to ensure the stability of whole ball-collecting rack.
As shown in Figure 2,3, front column 2 and rear column 3 are arranged on underframe 1 in parallel to each other, and bottom bar 7 before the bottom welding of front column 2 has, the two ends of front bottom bar 7 are respectively hinged at the front portion of underframe 1.Bottom bar 8 after the bottom welding of rear column 3 has, the two ends of rear bottom bar 8 are respectively hinged at the postmedian of underframe 1.It is respectively provided on two sides with operating handle 9, it is simple to operator grasps at rear column 3.
Being welded with two connecting rods 10 on the front bottom bar 7 of front column 2, two connecting rods 10 lay respectively at the two ends of front bottom bar 7, and are parallel to each other.End at each connecting rod 10 has been respectively articulated with a pull bar 11, and the end of two pull bars 11 is fixedly connected on same cross bar 12, and two pull bars 11 are parallel to each other, and connecting rod 10, pull bar 11 and cross bar 12 collectively form toggle.Being provided with some extension springs 13 on cross bar 12, one end of extension spring 13 is connected on cross bar 12, and the other end is connected on the hack lever of underframe 1 postmedian.When basketry is in extreme lower position, extension spring 13 is stretched to the longest, and when gradually heightening the height of basketry from extreme lower position, extension spring 13 gradually bounces back.
Telescopic advance lever 4 is for regulating the lifting of ball-collecting rack, and its one end is hinged on the bottom of front column 2, and the other end is hinged on the top of rear column 3.As in figure 2 it is shown, telescopic advance lever 4 by some joints stretch connect the body of rod be formed by connecting, its body of rod is tapered from down to up.Telescopic advance lever 4 is provided with multiple gear, the corresponding height of each gear, the body of rod that each gear is corresponding is respectively equipped with hole 14, location, after being adjusted to desired height, steady pin 15 is inserted hole 14, location internal locking.
When regulating basketry height from low to high, steady pin 15 is taken out, owing to there is the restoring force of extension spring 13, it is only necessary to the most before postpone column 3, now, telescopic advance lever 4 is gradually shortened, front column 2 and rear column 3 are rotated up around its respective hinge, make cylinder gradually erect, after reaching desired height, steady pin 15 is inserted in the hole, location 14 of respective notch, lock.Owing to there being extension spring 13 power-assisted, this regulation process is the most laborsaving, and a people can complete.
When regulating basketry height from high to low, steady pin 15 is taken out, operator only need to catch the operating handle 9 on rear column 3, firmly post-tensioning, and now telescopic advance lever 4 extends, front column 2 and rear column 3 rotate down around its respective hinge, making cylinder tilt backwards, extension spring 13 is gradually pulled open, after reaching desired height, steady pin 15 is inserted in the hole, location 14 of respective notch, lock.Due to the existence of extension spring 13, there is certain resistance in the motion of two columns, declines too many thus without moment, and controllability is the best.
As shown in Figure 1, 2, transverse arm 5 is erected at front column 2 and the top of rear column 3, and the end of transverse arm 5 is hinged with the top of rear column 3, and the middle part of transverse arm 5 is hinged with the top of front column 2.It is fixedly installed backboard 6 in the front end of transverse arm 5, for ensureing the bonding strength of transverse arm 5 and backboard 6, improve the safety of this ball-collecting rack, backboard pull bar 16 it is provided with between backboard 6 and transverse arm 5, the body of rod that backboard pull bar 16 bends for V-type, its bending end is fixedly connected on the top of transverse arm 5, and one free end is fixedly connected on the left part at backboard 6 back side, another free end is fixedly connected on the right part at backboard 6 back side, thus is formed and be stably connected with.
As shown in Figure 4, being provided with contiguous block on the front face of backboard 6, contiguous block includes rectangular connecting panels 17 and the folding frame 18 being vertically welded on connecting plate 17 plate face.Connecting plate 17 is fixedly connected on below the middle part of backboard 6 by connectors such as bolts, and folding frame 18 is in " Contraband " type, and rolls over the opening down of frame 18.
Basketry includes annular frame circle 19 and is welded on the adapter sleeve 20 outside frame circle 19, adapter sleeve 20 is set in the top of folding frame 18, it is provided with compression spring 21 in the lower section of folding frame 18, adapter sleeve 20, folding frame 18 and compression spring 21 by longitudinally through screw rod 22 connect, it is provided with nut, three to be fixed at the two ends of screw rod 22.Adapter sleeve 20 is made up of top board and the side plate being welded on top board both sides, and biside plate is parallel to each other, and folding frame 18 is clipped between biside plate, is bolted between side board and the side plate of adapter sleeve 20 of folding frame 18.
During assembling, the adapter sleeve 20 of basketry is set in the top of folding frame 18, bolt is used to be fixed by the side board of the side plate of adapter sleeve 20 with folding frame 18, screw rod 22 is penetrated again from top, and below screw rod 22, it is inserted in high intensity compression spring 21, then at the two ends up and down of screw rod 22 difference fastening nut, such connected mode can make basketry have certain elastic activity space.
For ensureing the personal safety of sportsman, it is respectively provided with protective pad 23 in the front end of the periphery of underframe 1 and front column 2, is damaged by support body preventing sportsman from bumping against on ball-collecting rack.
