[0053] As shown in FIG. 1, the telescopic lacing bar 2 is a horizontal bar parallel to the horizontal plane, the quantity of telescopic lacing bars 2 is arranged to be three, and the cross section formed by the three telescopic lacing bars 2 after being mounted on the support receptacle 1 is triangle-shaped, which is a relatively stable structure, furthermore, the telescopic lacing bar 2 in the middle is also located between the other two telescopic lacing bars 2 and is convenient for the user to lift the whole device in hand, and ball net lacing bars 3 as shown in FIG. 2 are upright bars which can be erected after rotation.
[0054] On the support receptacle 1 is provided a mounting position for installing the rotation positioning and angle adjusting structure 2, the rotation positioning and angle adjusting structure 2 includes a rotating shaft 111 and an adjusting part, the adjusting part is arranged on the rotating shaft 111, and the rotating shaft 111 is installed on the mounting position of the rotation positioning and angle adjusting structure 11 and on the rotating shaft 111 is provided a mounting position of the ball net lacing bar 112 for installing the ball net lacing bar 3. The positioning part 115 would lock the rotating shaft 111 onto the support receptacle 1 when the rotation positioning and angle adjusting structure 2 is installed onto the mounting position thereof, on the positioning part 115 is provided a fixing hole 1151 and a limiting groove 1152, which is a curved groove. The curved surface of the limiting groove 1152 is connected to the rotating shaft 11. And a screw passes each fixing hole 1151 and locks the positioning part 115 and the rotating shaft 11 onto the support receptacle 1.
[0055] As shown in FIG. 12 and FIG. 13, the essence of the rotation positioning and angle adjusting structure 11 is a rotation, positioning and snap-fit structure, wherein the rotation positioning and angle adjusting structure 11 can be any of the following structures.
[0056] As one embodiment of the present invention, the adjusting part in the rotation positioning and angle adjusting structure 11 comprises a rotary gear 113 and a positioning piece 116, i.e. the rotary gear 113 is the rotary part and the positioning piece 116 is the positioning part for stopping the rotation of the rotary gear 113.
[0057] The rotary gear 113 is fixedly mounted on the rotating shaft 111 of the rotation positioning and angle adjusting structure 11, the positioning piece 116 is mounted on a positioning control block 114, the positioning control block 114 limits the rotation of the rotary gear 113 by controlling the contact between the positioning piece 116 and the rotary gear 113, and one end of the positioning control block 114 is mounted on the support receptacle 1 by a shaft(i.e. one end of the positioning control block 114 is rotatable against the shaft), the other end of the positioning control block 114 is connected to a spring, the positioning piece 116 is located below the rotating shaft 111 when the spring rests. The structure of the above-mentioned positioning piece 116 and rotary gear 113 is merely one embodiment of the rotation positioning and angle adjusting structure 11, in fact, the rotary gear 113 engages with the positioning piece 116 opposite each other when the ball net lacing bars are rotated inward. Design of the positioning piece 116 and the rotary gear 113 running in opposite is for fixing the rotation angle of the rotation positioning and angle adjusting structure 11, and facilitating its angle adjustment. As a matter of fact, the positioning piece 116 and the rotary gear 113 are respectively a fixing part and a rotating part. The role of the fixing part is for fixing the rotation angle of the rotating part, which is convenient for users to stop at a necessary angle.
[0058] The above-mentioned rotation positioning and angle adjusting structure 11 is just a typical, simple and convenient operation mode of the present invention, but it is not the only way. As a simple modification of the present invention, the rotation positioning and angle adjusting structure 11 can be a relatively simple plug-pin fixing structure (as shown in FIGS. 19 and 20), or two gears running in opposite structure used in other fields, or the structure of a circular concavo-convex disk as shown in FIGS. 21 and 22. At the same time, based on usage condition, it is possible to replace the mechanical structure in the present embodiment with intelligently controlled mechanical structure among existing control methods such as electric control, magnetic control, oil control, or air control. For example, when to prepare a football net with a large support frame or a support frame for temporary large posters, control the rotation of the post and the angular positioning after rotation by electronic, magnetic, oil or air control will be more suitable.
[0059] On the support receptacle 1 is provided a limited bulge 14 for limiting the maximum rotation angle of the ball net lacing bar 3.
[0060] In the present embodiment, the ball net lacing bar 3 is a triangular net lacing bar with a section of triangular shape so as to better match the use of the limited bulge 14.
[0061] As shown in FIGS. 1 to 8, the quantity of telescopic lacing bars 2 is arranged to be three, the three telescopic lacing bars 2 are parallel to each other in space, and the cross section formed by the three telescopic lacing bars 2 after being mounted on the support receptacle 1 has a trianglular shape, wherein, a telescopic lacing bar 2 in the middle plays an important role in stabilizing the entire base.
[0062] The connection sleeves include the support connection sleeves 5 connected to telescopic lacing bars 2 located on both sides of support receptacle 1 and safe connection sleeves 43 connected to the telescopic lacing bars 2 located on the middle of the support receptacle 1.
[0063] The telescopic positioning assembly includes a limiting slot 45 provided on each connection sleeve and a limiting part 46 corresponding to the limiting slot 45, meanwhile, on the telescopic lacing bar 2 is correspondingly provided a positioning slot, and the length of the telescopic lacing bar is fixed after the limiting part 46 passes the limiting groove and the positioning slot in turn. The limiting part 46 may be a knife switch as shown in FIG. 11. In actual use, pulling the knife switch up, the telescopic lacing bar 2 is extendable to increase the stability of the entire post. At present, there are no base length adjustable ball net posts commercially available. For the convenience of outdoor use, the base length is generally smaller than the width of the net when fully extended (similar to FIG. 2). When total weight remains constant, the smaller the base length is, the worse the stability of the entire net post is. Therefore, it is proposed in the present invention that a technical solution wherein base length is adjustable, to overcome the deficiency in the art of difficult base length adjustment, and on the other hand, with the telescopic lacing bars, it is possible to store more facilities or article, and the space occupation is reduced too.
[0064] In practical application, the above solution can also be used as a portable tent support, which facilitates tent construction and storage. The solution of the present invention satisfies consumers' demands for posts to be portable, easy to retract, and convenient to build. Therefore, the solution of the present invention should be vigorously promoted in the field of post manufacture so that products in this field can better meet market demands.
[0065] The above embodiments are merely used for illustrating the present invention, but not limit the present invention. Those skilled in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
