Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

A portable assembled ball net for sports, comprising two bases 1, a vertical rod 2 is arranged above one of the bases 1, a ball net cylinder 3 is installed on the top of the vertical rod 2, and the ball net cylinder 3 A rotating rod 4 is arranged inside, and a bearing 5 is arranged between the bottom of the rotating rod 4 and the inside bottom of the net cylinder 3, and the bottom of the bottom of the rotating rod 4 is connected with the inner ring of the bearing 5, and the bearing The outer ring of 5 is fixedly connected with the inside bottom of the net cylinder 3, the top of the rotating rod 4 passes through the top of the net cylinder 3, and a bearing 5 is arranged between the rotating rod 4 and the top of the net cylinder 3, The upper part of the rotating rod 4 is fixedly connected with the inner ring of the bearing 5, the outer ring of the bearing 5 is fixedly connected with the top of the net tube 3, and the top of the rotating rod 4 is connected with the rocking handle 6. The middle part of the rotating rod 5 is connected to one side of the net 7, and one side of the net cylinder 3 is open, and the net 7 can pass through the opening of the net cylinder 3. The other end of the base 1 is connected to the moving rod 8, and a vertical connecting rod 9 is arranged above the other base 1, and grooves 10 are provided at the corresponding positions of the base 1 and the bottom end of the vertical rod 2 or the bottom end of the connecting rod 9. , the bottom end of the vertical bar 2 or the bottom end of the connecting rod 9 can be screwed into the groove 10, the middle part of the connecting rod 9 is provided with a through groove 11, and a vertical plate 12 is arranged in the through groove 11, A vertical elongated hole 13 is provided on the vertical plate 12, and the moving bar 8 can pass through the elongated hole 13. The two ends of the moving bar 8 are provided with a spring groove 14, and the spring groove 14 It is connected with one end of the spring 15, and the other end of the spring 15 is connected with one end of the stop rod 16. The end of the stop rod 16 located outside the spring groove 14 is provided with an external thread, and the inside of the spring groove 14 is An internal thread is provided, and one end of the limit rod 16 located outside the spring groove 14 can be threadedly engaged with the spring groove 14, and a universal wheel 17 is provided at each of the four corners of the bottom of the base 1 . In the present invention, two bases 1 are placed in place, and the base 1 can be moved conveniently through universal wheels 17, which is convenient for use; Threaded connection, pull moving bar 8 then and pull out ball net 7, this moment, stop bar 16 is threadedly engaged with spring groove 14 so that stop bar 16 is all positioned in spring slot 14, and move bar 8 rotates after passing elongated hole 13 The limit rod 16 thus makes one end of the limit rod 16 move out from the spring groove 14, and a ball bearing can be added between the limit rod 16 and the spring 15 to prevent the spring 15 from being damaged due to excessive twisting. After one end pops out from the spring groove 14, the length of the moving rod 8 increases so that it can no longer pass through the elongated hole 13, so that the ball net 7 exists stably; Pass through the long hole 13, then separate the vertical rod 2 and the connecting rod 9 from the base 1, wrap the ball net 7 around the rotating rod 4 through the crank handle 6, and then remove the base 1 and other components, which is easy to operate and convenient to use.

Specifically, since it is inconvenient to manually put away the ball net 7, in order to overcome the above-mentioned problems, a rotating drum 18 is arranged on the outer periphery of the rotating rod 4 described in this embodiment, and a torsion spring is arranged between the rotating rod 4 and the rotating drum 18. 19. One end of the torsion spring 19 is connected to the rotating rod 4, the other end of the torsion spring 19 is connected to the drum 18, and the drum 18 is connected to the ball net 7. When the ball net 7 is to be packed up, the torsion spring 19 resets under the action of torsion so as to realize the automatic packing up of the ball net 7, which is convenient to use.

Specifically, since the universal wheel 17 set under the base 1 is easy to move during use, in order to overcome the above-mentioned problems, the top of the universal wheel 17 described in this embodiment is connected to the wheel rod 20, and the bottom of the base 1 is connected to the wheel rod. The winning position of the rod 20 is provided with a wheel rod groove 21, the upper part of the wheel rod 20 is connected with one end of the screw rod 22, and the side wall of the wheel rod groove 21 is provided with a moving groove 23 at the corresponding position of the screw rod 22. The screw 22 can move along the moving slot 23 , the other end of the screw 22 is located outside the base 1 , and the screw 22 can be fixed by a nut 24 . When in use, the nut 24 is unscrewed, the screw rod 22 is moved to the side of the moving groove 23 away from the center of the base 1, and then the universal wheel 17 is rotated upwards with the rotation center of the screw rod 22 so that the base 1 contacts the ground, ensuring that the present invention is in use. stability.

More specifically, due to the high height of the vertical bar 2 plus the ball net cylinder 3 and the connecting rod 9, the stability is relatively poor. Each side is provided with a fixed rod 25, the bottom of the fixed rod 25 is hingedly connected with the base 1, and the top of the fixed rod 25 is provided with a semicircular clamp 26, and two corresponding clamps 26 Can be fixed on the outer periphery of vertical bar 2 or connecting rod 9 by bolt 27. The joint action of the fixing rod 25, the clip 26 and the bolt 27 can support the vertical rod 2 or the connecting rod 9, which effectively improves the stability of the present invention.

Further, since the vertical rod 2 and the connecting rod 9 with fixed lengths are inconvenient to adjust the height of the ball net 7, in order to overcome the above-mentioned problem, the vertical rod 2 and the connecting rod 9 described in this embodiment are telescopic rod structures. The vertical rod 2 and the connecting rod 9 of the telescopic rod structure can adjust the height of the ball net 7 conveniently and are convenient to use.

Furthermore, in order to save costs and facilitate transportation, the bottom of the base 1 is hollow and has poor stability. In order to overcome the above problems, a heavy object placement groove 28 is provided in the middle of the base 1 in this embodiment. The heavy object placement groove 28 can place heavy objects, which can effectively increase the weight of the base 1 and effectively increase the stability of the utility model, and the heavy objects can be found nearby, and the heavy objects can be moved out after exercise, which is simple to operate. Easy to use.

Furthermore, because the limit rod 16 is located at the end of the spring groove 14 outsides to be provided with an external thread, if it is directly rotated by hand, it is easy to scratch the hand, and when the limit rod 16 is unscrewed, there are fewer parts because the limit rod is positioned at the outer part. , it is difficult to unscrew, in order to overcome the above-mentioned problems, a "ten"-shaped groove 29 is set on the end of the stop rod 16 described in this embodiment located outside the spring groove 14, and the "ten"-shaped groove 29 can be combined with The "ten" block 30 is plugged and fitted, and the upper center of the "ten" block 30 is connected to the bottom of the "T" bar 31 . When the stop rod 16 is to be rotated, the "ten" block 30 is inserted into the "ten" groove 29, and the "T" bar 31 is rotated simultaneously so that the stop rod 16 can be easily driven to rotate.
