BACKGROUND

Since living standards of people are increasingly improved, outdoor ball sports are favored by the people, a goal is an indispensable configuration for the outdoor ball sports, which generally needs to be carried outside and then installed or disassembled after arriving at a designated location.

A limiting post 140 is disposed at a position on the second connecting member 130 of the second housing 123 corresponding to the rotating shaft hole 124, the limiting post 140 is a hollow structure, and two ends of the limiting post 140 respectively define two first openings 127, the first openings 127 correspond to the rotating shaft hole 124, and the rotating shaft 122 passes through the rotating shaft hole 124 and extends into the limiting post 140. A torsion spring 141 is sleeved on an outer side of the limiting post 140, the torsion spring 141 includes a first end 142 and a second end 143, the first end 142 is connected to the second connecting member 130 of a corresponding first housing 121, and the second end 143 is connected to the second connecting member 130 of a corresponding second housing 123. The first limiting member 131 includes a first limiting plate 144 disposed on the second connecting member 130 of the first housing 121, the first limiting member 133 includes a limiting housing 150 disposed in the second connecting member 130 of the second housing 123, the first limiting end 134 is a second limiting plate 151 disposed in the limiting housing 150, and the second limiting end 135 is a third limiting plate 152 disposed in the limiting housing 150. When the goal frame 100 is switched from the unfolded state to the folded state, a user needs to apply an external force to each first housing 121 to drive each first housing 121 to rotate with respect to the corresponding second housing 123, since the first end 142 of the torsion spring 141 is connected to the second connecting member 130 of the corresponding first housing 121, the first housing 121 drives the torsion spring 141 to rotate, and the torsion spring 141 is compressed. When the first limiting plate 144 abuts against the second limiting plate 151, the torsion spring 141 is compressed to a maximum compression stroke, and at this time, the goal frame 100 is completely folded. Since the torsion spring 141 has an elastic force, in order to prevent the torsion spring 141 from automatically resetting, the goal frame 100 is automatically unfolded, and after the goal frame 100 is folded, the goal frame 100 needs to be fixed by using the strap, the hook and loop fastener, the storage bag, etc., that is, the goal frame 100 is kept in the folded state only by the external force. When the goal frame 100 needs to be used, only the external force needs to be released, such as unfastening the strap, the hook and loop fastener, etc. At this time, the external force bound to the goal frame 100 disappears, and the torsion spring 141 extends under action of the elastic force, since the first end 142 of the torsion spring 141 is connected to the second connecting member 130 of the corresponding first housing 121, the torsion spring 141 drives the first housing 121 to rotate. When the torsion spring 141 is reset, the goal frame 100 is fully unfolded, and the first limiting plate 144 abuts against the third limiting plate 152. Compared with the prior art, the present disclosure only needs to complete a folding operation of the goal frame 100 when the goal frame 100 needs to be stored, and when the goal frame 100 needs to be used, the goal frame 100 can be automatically unfolded without user operation, which greatly improves convenience of use and is convenient for the user to use.

In the present disclosure, the first connecting member 125 of the first housing 121 and the first connecting member 125 of the second housing 123 are both in tubular shapes, so that after the first connecting member 125 of each first housing 121 and the first connecting member 125 of each second housing 123 are connected to each of the transverse rods and each of the supporting rods of the goal frame 100, ends of each of the transverse rods and ends of each of the supporting rods are wrapped, while each of the ends is protected, structural strength of each of the ends is also increased, so that each of the transverse rods and each of the supporting rods of the goal frame 100 are more stable when being folded or unfolded. And the second connecting member 130 of the first housing 121 and the second connecting member 130 of the second housing 123 are both cylindrical housing structures, and other structures such as the rotating shaft 122 are wrapped inside the first housing 121 and the second housing 123 without being exposed to a surface of the goal frame 100, which is beneficial to improving an overall aesthetic degree of the goal frame 100.

In addition, the limiting post 140 is disposed on the second connecting member 130 of each second housing 123, and when each of the movable corner joints 120 is assembled, the rotating shaft 122 in the second connecting member 130 of each first housing 121 is inserted into a corresponding limiting post 140, so that the rotating shaft 122 may only rotate in the corresponding limiting post 140 to maintain rotation stability of the rotating shaft 122, so that the first housing 121 rotates relatively stably with respect to the second housing 123. Moreover, each torsion spring 141 respectively connected to a corresponding first housing 121 and a corresponding second housing 123 is further sleeved on the outer side of the limiting post 140, and each torsion spring 141 generates torsion in the rotation process of the corresponding first housing 121 and the corresponding second housing 123, so that the goal frame 100 is automatically unfolded, and a specific process is as follows:

• • When the goal frame 100 is folded, each of the transverse rods and each of the supporting rod of the goal frame 100 rotate through the corresponding movable corner joints 120, in each of the movable corner joints 120, the second connecting member 130 of the first housing 121 rotates with respect to the second connecting member 130 of the second housing 123, so that the torsion spring 141 connected between the second connecting member 130 of the first housing 121 and the second connecting member 130 of the second housing 123 is twisted to compress and deform to generate torsion, after the goal frame 100 is fully folded, the torsion spring 141 is twisted to a maximum torsion state, the first limiting plate 144 of the first housing 121 abuts against the third limiting plate 152 of the limiting housing 150 in the second housing 123, the first housing 121 does not continue to rotate with respect to the second housing 123 to keep the goal frame 100 in the long strip shape, and at this time, the goal frame 100 may be bundled by mounting the hook and loop fastener on an outside of the goal frame 100, so that the goal frame 100 is kept in a contracted and folded state, so that the goal frame 100 is convenient to carry and store.
  • When the goal frame 100 needs to be unfolded, only the hook and loop fastener on the goal frame 100 needs to be removed, at this time, in each of the movable corner joints 120, the torsion spring 141 connected to the first housing 121 and the second housing 123 release torsion in order to restore deformation, and in a process that the torsion spring 141 releases the torsion, the first housing 121 and the second housing 123 are automatically driven to rotate with respect to each other, so that the corresponding transverse rod and the corresponding supporting rod connected to the first housing 121 and the second housing 123 are unfolded respectively, after the torsion spring 141 completely releases the torsion, the goal frame 100 is completely unfolded, and the first limiting plate 144 of the first housing 121 abuts against the second limiting plate 151 of the limiting housing 150 of the second housing 123, the first housing 121 does not continue to rotate with respect to the second housing 123, so that each of the transverse rods and each of the supporting rods are finally maintained in a form of the goal 10, so that the goal frame 100 is automatically unfolded, which is convenient and quick to use.

In order to prevent the goal frame 100 from being automatically unfolded too fast and improve safety of the goal frame 100, the present disclosure further improves a structure of each of the movable corner joints 120, specifically as follows:

FIG. 5 is a schematic diagram of a movable corner joint of a goal frame according to a second embodiment of the present disclosure, the second embodiment shown in FIG. 5 is an improvement based on FIG. 4, a buffer layer 153 is filled between the limiting post 140 and the rotating shaft 122, the buffer layer 153 is made of damping material.

In the present disclosure, the buffer layer 153 is filled between the limiting post 140 and the rotating shaft 122, the buffer layer 153 is may be formed of a damping oil or a damping adhesive. For example, the damping adhesive is filled between the limiting post 140 and the rotating shaft 122, when the first housing 121 and the second housing 123 are unfolded by the torsion spring 141, the torsion spring 141 releases a large torsion at a moment of unfolding, and the first housing 121 is driven to rotate with respect to the second housing 123 during a restoring deformation process, at this time, the rotating shaft 122 of the first housing 121 rotates in the limiting post 140 of the second housing 123, and during a rotating process, the damping adhesive is used for buffering, so as to slow down a rotation speed between the first housing 121 and the second housing 123. When the external force disappears, the goal frame 100 is automatically opened to be in the unfolded state, that is, when the hook and loop fastener for binding the goal frame 100 is untied, as a binding force disappears, the torsion spring 141 after being compressed is restored under the elastic force. In order to avoid a restoring speed of the torsion spring 141 is too fast to cause the goal frame 100 to expand too fast and accidentally hit the user, the buffer layer 153 is filled between the limiting post 140 and the rotating shaft 122 to buffer the elastic force of the torsion spring 141, so that a rotation speed between each of the transverse rods and each of the supporting rods when the goal frame 100 is automatically unfolded is effectively reduced, which is beneficial to improving safety of the goal frame 100.

In addition, in order to further reduce the size of goal frame 100 after being folded, so that the occupied area of the goal frame 100 is further reduced, the goal frame 100 is convenient to store and carry, the present disclosure further improves structures of each of the transverse rods and each of the supporting rods of the goal frame 100, specifically as follows:

FIG. 6 is a schematic diagram of an unfolded state of a goal frame according to a third embodiment of the present disclosure, FIG. 7 is a schematic diagram of a folded state of the goal frame according to the third embodiment of the present disclosure. As shown in FIG. 6 and FIG. 7, the first transverse rod 110, the first transverse rod 111, the first supporting rod 112, the second supporting rod 113, the third supporting rod 114, and the fourth supporting rod 115 each includes a first rod 170 and a second rod 172, and the first rod 170 and the second rod 172 are both hollow structures. The first rod 170 includes a first telescopic end 174 and a first connecting end 175, the second rod 172 includes a second telescopic end 176 and a second connecting end 177, the first telescopic end 174 is close to the second telescopic end 176, and the first connecting end 175 is distal from the second connecting end 177, the first connecting end 175 and the second connecting end 177 are respectively connected to corresponding movable corner joints 120, the first telescopic end 174 is nested in the second rod 172 and extends and retracts along a length direction of the second rod 172. A limiting protrusion 171 is disposed on the first telescopic end 171, the second telescopic end 176 defines a limiting groove 173 at a position corresponding to the limiting protrusion 171, and the limiting protrusion 171 is embedded in the limiting groove 173

In an embodiment, each of the transverse rods and each of the supporting rods of the goal frame 100 are each composed of the first rod 170 and the second rod 172 that extend and retract to each other, the first connecting end 175 and the second connecting end 177 are respectively connected to corresponding movable corner joints 120 for folding between each of the transverse rods and each of the supporting rods. The first telescopic end 174 is embedded into the second rod 172, so that the first rod 170 moves in a length extension direction of the second rod 172 through the first telescopic end 174 to realize extension and retraction between the first rod 170 and the second rod 172, thereby adjusting overall lengths of each of the transverse rods and each of the supporting rods.

When the goal frame 100 needs to be unfolded, only each of the transverse rods and each of the supporting rods need to be rotated by corresponding movable corner joints 120 firstly, so that the goal frame 100 is integrally unfolded. And then, the first rod 170 of each of the transverse rods is pulled out with respect to a corresponding second rod 172, and the first rod 170 of each of the supporting rod is pulled out with respect to a corresponding second rod 172, when the first telescopic end 174 extends outwards to a maximum distance along the length direction of the corresponding second rod 172, the limiting protrusion 171 of the first telescopic end 174 is just embedded into the limiting groove 173 of a corresponding second telescopic end 174, so that the first rod 170 is fixed with respect to the corresponding second rod 172, which is beneficial to enhancing structural stability of the goal frame 100 and finally forming a complete goal frame 100.

When the goal frame 100 needs to be folded, firstly, the limiting protrusion 171 on the first rod 170 is pressed down to separate the limiting protrusion 171 from the limiting groove 173 of the corresponding second rod 172, and then, the first rod 170 is retracted into the second rod 172, thereby effectively shortening lengths of each of the transverse rods and each of the supporting rods, and then each of the transverse rods after being contracted and each of the supporting rods after being contracted are folded in sequence, the size of the goal frame 100 is further reduced in a folding manner, and finally, the goal frame 100 is integrally in the long strip shape. In this way, by two different ways of contracting and folding, the occupied area after the goal frame 100 is folded is reduced, which is convenient for storage and improves portability of the goal 10.
