[0056] Example

[0057] Please refer to Figure 1-Figure 8 As shown, this embodiment provides a goal, including a goal frame 1 and a net 2 covered on the goal frame 1.

[0058] Specifically, the goal frame 1 includes a door frame 11 and a bottom frame 12 that is rotatably folded or rotationally fixed to the bottom of the door frame 11. When the door frame 11 is rotated to be close to the bottom frame 12, the goal frame 1 is in a folded state. When not in use, the goal frame 1 can be folded for easy storage; when the door frame 11 is rotated to form a certain angle with the bottom frame 12, the angle between the door frame 11 and the bottom frame 12 is locked, which is the use state of the goal frame 1. In order to ensure the stability of the goal frame 1 in the use state, the door frame 11 can be rotated to have an angle of 90° with the bottom frame 12, so that the goal frame 1 can be placed on the ground more stably.

[0059] Further, in order to increase the stability of the goal frame 1, two first plugging grooves 1433 are symmetrically arranged at two corners of the door frame 11 away from the bottom frame 12, and two second plugging grooves 1434 are symmetrically arranged at two corners of the bottom frame 12 away from the door frame 11, that is, one first plugging groove 1433 and one second plugging groove 1434 are located on one side of the goal frame 1 and are arranged correspondingly, and the other first plugging groove 1433 and the other second plugging groove 1434 are located on the other side of the goal frame 1 and are arranged correspondingly. Correspondingly, a deformation rod 13 is arranged between the first plug-in slot 1433 and the second plug-in slot 1434 located on the same side. The deformation rod 13 is an elastic deformation rod. The material of the deformation rod 13 can be glass fiber. The deformation rod 13 can be bent when subjected to force and can restore the deformation after the force disappears. The deformation rod 13 can be a straight rod or an arc rod. The arc rod is more easily deformed by force, while the straight rod can restore the vertical state after the force disappears, which is convenient for storage. The preferred deformation rod 13 is a straight rod. When in use, one end of the deformation rod 13 is inserted into the first insertion groove 1433, and the other end of the deformation rod 13 is inserted into the second insertion groove 1434 corresponding to the first insertion groove 1433 and located on the same side. Since the length of the deformation rod 13 is greater than the linear distance between the first insertion groove 1433 and the second insertion groove 1434 located on the same side, the deformation rod 13 is bent under the force applied to the deformation rod 13 by clamping the two ends of the deformation rod 13 in the first insertion groove 1433 and the second insertion groove 1434, and an arc-shaped support surface is formed between the two deformation rods 13 to prop open the net 2 covered on the goal frame 1, and the deformation rod 13 and the adjacent gate rod 111 and bottom rod 121 form a stable triangular structure, which improves the stability of the goal frame 1 and makes the goal suitable for games of different sizes. When not in use, the deformation rod 13 is disassembled, and the deformation rod 13 can return to a vertical state after the force disappears, which is convenient for storage.

[0060] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the door frame 11 includes a plurality of door rods 111 and a plurality of first L-shaped connecting members 112 connecting the plurality of door rods 111, the bottom frame 12 includes a plurality of bottom rods 121 and a plurality of second L-shaped connecting members 122 connecting the plurality of bottom rods 121, the plurality of door rods 111 are connected end to end through a plurality of first L-shaped connecting members 112 to form a rectangular door frame 11, the plurality of bottom rods 121 are connected end to end through a plurality of second L-shaped connecting members 122 to form a rectangular bottom frame 12, and in order to enable the goal frame 1 to be folded into a portable size after being folded, in a preferred embodiment, three door rods 111 are provided and are connected end to end through two first L-shaped connecting members 112 to form a rectangular door frame 11 with an opening on one side, three bottom rods 121 are provided and are connected end to end through two second L-shaped connecting members 122 to form a rectangular bottom frame 12 with an opening on one side, and the open ends of the door frame 11 and the bottom frame 12 are rotatably folded or rotatably fixedly connected, so please refer to Figure 4 As shown, after the door frame 11 and the bottom frame 12 are folded together, the door rod 111 and the bottom rod 121 can be further folded and collected, so that the goal frame 1 is more portable after being folded.

[0061] Furthermore, since the door frame 11 is formed by connecting a plurality of door rods 111 and a plurality of first L-shaped connectors 112, the first plug-in groove 1433 is arranged at the corner of the first L-shaped connector 112; the bottom frame 12 is formed by connecting a plurality of bottom rods 121 and a plurality of second L-shaped connectors 122, and the second plug-in groove 1434 is arranged at the corner of the second L-shaped connector 122, therefore, the goal frame 1 can be disassembled for convenient storage and carrying, and when any parts are damaged, it is convenient to replace them without replacing the entire goal frame 1, which can save maintenance costs.

[0062] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, a third L-shaped connector 14 that is rotationally folded or rotationally fixed is arranged between the door frame 11 and the bottom frame 12, the open end of the door frame 11 and the open end of the bottom frame 12 are connected through the third L-shaped connector 14, and the first L-shaped connector 112 has the same structural arrangement as the third L-shaped connector 14, and the second L-shaped connector 122 has the same structural arrangement as the third L-shaped connector 14.

[0063] Specifically, the third L-shaped connector 14 includes a first joint 141 , a second joint 142 and a reinforcing column core 143 .

[0064] The first joint 141 is a hollow tubular structure, the first joint 141 includes a first connecting portion 1411 and a first arc portion 1412 formed by bending and extending one end of the first connecting portion 1411 toward the distal end, and the inner bending portion of the first joint 141 extends toward the distal end to form two symmetrically arranged annular sleeves 1413; the second joint 142 is a hollow tubular structure, the second joint 142 includes a second connecting portion 1421 and a second arc portion 1412 formed by bending and extending one end of the second connecting portion 1421 toward the distal end. The arc portion 1422 and the inner curved portion of the second joint 142 are integrally formed with a hollow shaft column 1423, and the shaft column 1423 is sleeved in the annular sleeve 1413 and fits with the inner circle of the annular sleeve 1413, so that the second joint 142 can rotate around the center point where the shaft column 1423 and the annular sleeve 1413 are sleeved to perform articulated motion, and the second joint 142 and the first joint 141 are always connected through the shaft column 1423 and the annular sleeve 1413, and will not be completely separated during articulated motion. Specifically, the second arc portion 1422 is movably arranged in the first arc portion 1412. When the second joint 142 is rotated to make the second arc portion 1422 rotate toward the first arc portion 1412 and lock the position, the first L-shaped connector 112, the second L-shaped connector 122 and the third L-shaped connector 14 are in a rotational fixed state; when the second joint 142 is rotated to make the second arc portion 1422 rotate away from the first arc portion 1412, the first L-shaped connector 112, the second L-shaped connector 122 and the third L-shaped connector 14 are in a rotational folded state.

[0065] In addition, the reinforcing column core 143 is arranged in the shaft column 1423, and one end of the reinforcing column core 143 is provided with a clamping block 1431 clamped with the annular sleeve 1413 on one side, and the other end of the reinforcing column core 143 is radially extended outward and provided with a limiting portion 1432 clamped with the annular sleeve 1413 on the other side, so that the reinforcing column core 143 is firmly connected with the shaft column 1423 and the annular sleeve 1413, thereby strengthening the strength of the connection between the first joint 141 and the second joint 142, and improving the bearing capacity of the first L-shaped connector 112, the second L-shaped connector 122, and the third L-shaped connector 14, so as to ensure the stability of the goal frame 1. The first plug-in slot 1433 and the second plug-in slot 1434 for plugging the deformation rod 13 are arranged on the other end of the reinforcing column core 143.

[0066] like Figure 6 and Figure 8 As shown, in this embodiment, the middle portion of the reinforcing column core 143 is indented inward and is provided with a zoom gap groove 1435 which is open toward one end of the reinforcing column core 143 .

[0067] Specifically, the scaling gap groove 1435 is formed by opening the middle part of the reinforcing column core 143 toward one end of the reinforcing column core 143, so that the reinforcing column core 143 has a gap that can be radially expanded and contracted. When the reinforcing column core 143 is squeezed, the reinforcing column core 143 can shrink toward the center. After the size of the reinforcing column core 143 is reduced, it can smoothly extend into the shaft column 1423. The reinforcing column core 143 is loosened, the size of the reinforcing column core 143 is restored, and it is clamped with the annular sleeves 1413 on both sides through the clamping block 1431 and the limiting portion 1432, thereby ensuring that the reinforcing column core 143 is firmly connected to the shaft column 1423 and the annular sleeve 1413, thereby strengthening the bearing capacity of the first L-shaped connector 112, the second L-shaped connector 122 and the third L-shaped connector 14, and improving the stability of the goal.

[0068] like Figure 8 As shown, in this embodiment, the inner ring of the annular sleeve 1413 is indented toward the outer ring direction of the annular sleeve 1413 to form a clamping groove 14131. Since the annular sleeve 1413 is symmetrically arranged on both sides of the first joint 141 and is sleeved on both ends of the shaft column 1423, the clamping block 1431 is clamped with the clamping groove 14131 of the annular sleeve 1413 on one side, and the limiting portion 1432 is clamped with the clamping groove 14131 of the annular sleeve 1413 on the other side, so that the reinforcing column core 143 can be firmly connected with the shaft column 1423 and the annular sleeve 1413.

[0069] like Figure 7 and Figure 8 As shown, in this embodiment, a accommodating cavity 1424 is provided in the second arc portion 1422, and the accommodating cavity 1424 opens toward the side wall of the second arc portion 1422 to form a first opening 1425, and the side wall of the first arc portion 1412 is provided with a second opening 14121 matching the first opening 1425; an elastic clamping member 1426 is provided in the accommodating cavity 1424, and the elastic clamping member 1426 includes a pressing block 14261 and an elastic bending piece 14263 arranged at the bottom of the pressing block 14261, the pressing block 14261 is protruding from the first opening 1425, and two hooks 14262 that are clamped to the first opening 1425 are symmetrically arranged at the bottom of the pressing block 14261.

[0070] Specifically, the accommodating cavity 1424 is used to accommodate the elastic locking piece 1426. When the pressing block 14261 is pressed, the bottom of the elastic bending piece 14263 abuts against the bottom surface of the accommodating cavity 1424. Therefore, the elastic bending piece 14263 is compressed and deformed under the action of force, so that the pressing block 14261 moves downward, and then the top surface of the pressing block 14261 is lower than the first opening 1425. At this time, the second arc portion 1422 can rotate toward the first arc portion 1412. When it rotates to the position where the first opening 1425 overlaps with the second opening 14121, the pressing block 14261 is released, the elastic bending piece 14263 restores its deformation, and the pressing block 14261 pops out of the first opening 1425 and the second opening 14121. The hook 14262 is re-engaged on the first opening 1425 to lock the position of the first joint 141 and the second joint 142. When it is necessary to fold the first L-shaped connector 112 or the second L-shaped connector 122 or the third L-shaped connector 14, press the button 14261 so that the top surface of the button 14261 is lower than the position of the first opening 1425 and the second opening 14121, and the hook 14262 moves downward with the button 14261 to release the engagement with the first opening 1425, thereby releasing the lock on the position of the first joint 141 and the second joint 142, and then the second arc portion 1422 can be rotated in the direction away from the first arc portion 1412, so that the first joint 141 and the second joint 142 can be rotated and folded.

[0071] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, a latch 14112 is provided on the side walls of the first connecting portion 1411 and the second connecting portion 1421, a clearance hole 14111 is provided around the latch 14112, and a latch that engages with the latch 14112 is provided on the door rod 111 and the bottom rod 121 (not shown in the figure).

[0072] Specifically, the first connecting part 1411 is provided with a structure of a snap-fitting piece 14112, and the second connecting part 1421 is also provided with a structure of a snap-fitting piece 14112, and the first L-shaped connecting part 112, the second L-shaped connecting part 122 and the third L-shaped connecting part 14 have the same structural arrangement, and the snap-fitting piece 14112 is an elastic structure protruding toward the inside of the first connecting part 1411 and the second connecting part 1421, and a through hole 14111 is arranged to pass through the side walls of the first connecting part 1411 and the second connecting part 1421, thereby providing a movable space for the snap-fitting piece 14112 to move toward the outside of the first connecting part 1411 and the second connecting part 1421. For example, when the door rod 111 extends into the first connection part 1411 of the first L-shaped connecting member 112, the latch 14112 will be pushed out toward the outside of the first connection part 1411 by the door rod 111, thereby making way for the door rod 111 to move up and down in the first connection part 1411, so that the door rod 111 can move smoothly. When the door rod 111 moves to the position where the latch and the latch 14112 are engaged, the latch 14112 can be engaged with the latch to lock the connection between the door rod 111 and the first L-shaped connecting member 112. When disassembling the goal, the latch 14112 can be pushed outward to release the engagement between the latch 14112 and the latch, and the door rod 111 can be removed. The disassembly and assembly are simple and convenient.

[0073] In this embodiment, the edge of the net 2 is provided with a Velcro cover (not shown in the figure) for fitting onto the goal frame 1. The Velcro cover can be Velcro, which is convenient for installation and removal. When the goal is not in use, the net 2 is removed, and then the goal frame 1 is folded or disassembled for easy storage and carrying.

[0074] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
