The pressure spring 43 is accommodated in the displacement space 441 inside the second fixing sleeve 44 and abuts between the pivot tube 42 and the second fixing sleeve 44 .

As shown in Figure 1, the opening and folding process of the net support is as follows: hold the pivot tube 42 with your hand and apply force to the direction of the second fixed sleeve 44 (that is, to the right), so that the pressure spring 43 is compressed, and the pivot tube 42 It can drive the net support frame 30 to move to the right as a whole. At this time, the first concave position 411 between the joint surface of the pivot tube 42 and the first fixed sleeve 41 is separated from the block 421. After the limit is released, the pivot tube 42 The net support frame 30 can be integrally rotated around the upper cross bar 11 of the door frame 10. If the goal needs to be folded, the net support frame 30 can be bent down to be aligned with the door frame 10 and then let go, so that the pressure spring 43 produces Elastic recovery, so that the pivot tube 42 and the net support frame are pushed back to the left side as a whole, and the block 421 of the pivot tube 42 is locked in the second recess 412 of the first fixed sleeve 41 again, so that the net support is realized. The folding action of frame 30 (see Figure 2).

As shown in FIGS. 1 to 3 , the underframe 20 is a U-shaped structure integrally connected by a lower cross bar 21 and two horizontal bars 22 . The lower cross bar 21 is connected between the two horizontal bars 22 by overlapping, plugging, screwing, welding or integral molding. The second pivot assembly 50 realizes the pivot connection between the horizontal bar 22 and the vertical bar 12 of the aforementioned door frame 10 .

As shown in FIGS. 7 and 8 , the second pivot assembly 50 includes a fixing clip 51 , an elastic clip 52 and a pivot shaft 53 . The fixing clip 51 includes a first connecting portion 511 and a second connecting portion 512 integrally connected, the first and second connecting portions 511, 512 are perpendicular to each other to form an L-shaped structure, and the first connecting portion 511 is fixed on the horizontal bar 22 The second connecting portion 512 is rotatably connected to the bottom end of the vertical bar 12 through the pivot shaft 53 . In this embodiment, the first connecting part 511 has a first installation groove 513 with a U-shaped cross section, the end of the horizontal bar 22 is welded in the first installation groove 513, and the second connecting part 512 has a U-shaped cross section. U-shaped second installation slot 514 , the vertical bar 12 extends into the second installation slot 514 . The pivot shaft 53 is a long screw passing through the second connecting portion 512 and the vertical rod 12, and the end of the long screw is tightened with a nut, which has the advantages of easy material acquisition and convenient production. A buckle hole 515 is provided on the second connecting portion 512 above the pivot point, and the elastic clip 52 includes a V-shaped elastic portion 521 and a buckle point 522 located outside the end of the elastic portion 521 . The buckle point 522 is provided with a through hole 122 at the lower end of the vertical bar 12; when the goal is opened, the through hole 122 is aligned with the button hole 515 of the second connecting portion 512, and the buckle point 522 protrudes from the through hole 122 of the vertical bar 12 Fasten in the button hole 515 , when the goal is folded, the through hole 122 and the button hole 515 are staggered, and the bottom frame 20 is folded up as a whole and stacked on the door frame 10 .
