Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically relating to a foldable portable soccer goal frame structure. Background Technology

[0002] With the continuous development of sports and fitness activities, especially football, the technical requirements for football goals in sports and fitness equipment are also becoming increasingly higher. A football goal is a frame-like structure set at both ends of the field, serving as the target for shooting. In known technologies, existing football goals (frames) mainly consist of a goal frame with two vertical posts, end frames, and a rear crossbar. The connection between the two end frames and the two goal posts, as well as between the bottom of the end frames and the rear crossbar, primarily uses an inner and outer tubing inlay connection, secured with fastening screws to form a fixed football goal (frame). However, due to its structural limitations, its design is complex and cumbersome. Once a football goal is fixedly installed on the sports field, it is inconvenient to move or free up space, hindering the full utilization of the field for other sports activities and causing numerous inconveniences to the "multi-purpose use" of the sports field.

[0003] Therefore, a new type of folding soccer goal, with announcement number "CN205598568U", is proposed. It features connecting pipes welded to the upper and lower ends of the two goalposts, each with two pin holes. U-shaped clamps with two pin holes are welded to the upper and lower front ends of the two end frames. Pin bolts are inserted into the pin holes at the top of the U-shaped clamps at the upper and lower ends of the two end frames, and handle screws are installed in the other pin hole, corresponding to the connecting pipes of the two goalposts. Pin holes are also formed on the outer ends of the rear of the two end frames. U-shaped clamps are welded to both ends of the rear crossbar, and handle screws are attached to the U-shaped clamps at both ends of the rear crossbar, connecting to the two end frames. Its structure is simple and practical, easy to move, and suitable for soccer teaching, training, practice, and matches.

[0004] However, while the aforementioned new type of folding soccer goal has some drawbacks when it's necessary to move the goal to make room for other sports, it still has the following significant limitations: The folding method only folds the two end frames to the side of the goal frame crossbar; it cannot fold the rear crossbar or the front goal frame. Since the length of these components doesn't change after folding the end frames, the folded goal is quite long and takes up considerable space when stored. Utility Model Content

[0005] The purpose of this invention is to provide a foldable portable soccer goal frame structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable portable soccer goal frame structure, comprising:

[0007] A football goal frame A has a folding support frame rod A that can be folded and retracted into a flat shape and unfolded to support the football goal frame at the bottom corner of the inner side of the football goal frame A. At the obliquely symmetrical position of the folding support frame rod A and at the upper corner of the inner side of the football goal frame A, there is a folding support frame rod B that folds and unfolds to support the upper end of the football goal frame in the direction of the goal.

[0008] The football goal frame B has a through folding cavity A that allows the folding support frame rod A to extend and retract. The inner side of the football goal frame B has a through folding cavity B at one end of the folding support frame rod B that allows the folding support frame rod B to extend and retract, thus unfolding the football goal frame.

[0009] Preferably, the football goal frame A and football goal frame B are integrally welded together, and the upper and lower ends of the football goal frame B are provided with magnetic adsorption blocks that magnetically attract the folding support door frame rods A and B to the outside of the football goal frame B after folding. When the folding support door frame rods A and B are folded, the magnetic adsorption blocks can firmly attract them to the outside of the football goal frame B. This not only prevents the folded door frame rods from shaking randomly, ensuring the compactness of the overall structure, but also makes it more convenient to transport and store, without worrying about the door frame rods accidentally unfolding, further saving storage space.

[0010] Preferably, the two obliquely symmetrical corners on the inner side of the football goal frame A are provided with fixed posts, and one end of each fixed post is provided with a connecting seat. The presence of the connecting seat ensures that the goal frame rod can rotate smoothly without jamming or getting stuck. When the support is extended, it ensures that the goal frame rod is tightly connected to the football goal frame A, providing stable support for the football goal frame and ensuring the safety and reliability of the football goal during use.

[0011] Preferably, one end of the folding support door frame rod A and the folding support door frame rod B is movably connected to the connecting seat by a pin, and the other end of the folding support door frame rod A and the folding support door frame rod B passes through the through folding cavity A and the through folding cavity B on the football goal frame B and is provided with a limiting plate to ensure that the door frame rod can be accurately positioned when folded and unfolded to the predetermined position, so as to avoid affecting the normal use and storage effect of the football goal due to the loss of control of the position of the door frame rod.

[0012] Preferably, the lower end faces of the football goal frame A and football goal frame B are provided with blocking support strips to support the football goal frame on the ground. The blocking support strips are in full contact with the ground, distributing the weight of the football goal, increasing the friction with the ground, and preventing the football goal from sliding or tipping over during use.

[0013] Preferably, the lower end faces of the goal frame A and the football goal frame B are provided with omnidirectional casters that allow the football goal frame to be moved and transported after being folded and unfolded. With just a gentle push, the omnidirectional casters can flexibly turn, allowing the football goal to easily reach the designated position.

[0014] Preferably, the inner cavities of the goal frame A and the football goal frame B are uniformly provided with metal hooks for attaching the football net to the football goal frame, so that the football net can be firmly installed on the football goal frame. The uniformly distributed design ensures that the football net can be evenly distributed on the football goal frame when under force, avoiding damage or detachment of the football net due to excessive local force.

[0015] Preferably, locking blocks are provided on the bottom sides of both ends of the goal frame A and the football goal frame B, and conical iron stakes are threaded through the locking blocks to fix the football goal frame to the ground after it is unfolded. By screwing the conical iron stakes into the ground through the locking blocks, the football goal can be firmly fixed to the ground. Especially during formal matches or high-intensity training, the football goal needs to maintain absolute stability.

[0016] Compared with existing technologies, the technical effects and advantages of this utility model are as follows: This foldable portable soccer goal frame structure...

[0017] This invention, through unique folding support door frame rods A and B, combined with through-folding cavities A and B on the football goal frame B, allows the football goal frame to be retracted into a flat shape, successfully solving the problem of the rear ground crossbar and front goal frame being unable to fold. This significantly reduces the length and space occupied by the folded football goal, making it less space-consuming whether placed horizontally or vertically, thus improving storage convenience. Furthermore, the magnetic adsorption blocks on the exterior of the football goal frame B further ensure a compact structure after folding, preventing the goal frame rods from wobbling or accidentally unfolding, providing greater convenience for handling and storage.

[0018] The supporting strips on the lower surfaces of the goal frame (A and B) effectively distribute the weight of the goal, increasing friction with the ground and preventing it from sliding or tipping over during use, providing reliable support even on uneven surfaces. Locking blocks and tapered iron stakes on both bottom ends securely fix the goal to the ground after unfolding, meeting the stringent stability requirements of official matches and high-intensity training. Regarding ease of movement, the omnidirectional casters on both sides of the lower surface of the goal frame allow for easy movement both folded and unfolded. A gentle push is all it takes to flexibly turn and reach the designated position, significantly saving manpower and time costs, solving the problem of inconvenient movement of traditional football goals, and significantly improving the practicality and applicability of the goal.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6This utility model provides a technical solution: a foldable portable soccer goal frame structure, comprising:

[0028] The football goal frame A1 has a hinged folding support frame rod A2 at its inner bottom corner. This rod allows the goal frame to be folded and retracted into a flat shape, and also provides support when unfolded. Folding support frame rod A2 is a key component for enabling the football goal's folding function. When the football goal needs to be folded, it rotates around the hinge point with the goal frame A1, causing the goal frame to retract into a flat shape, thus greatly reducing the footprint of the football goal and facilitating storage and transportation. In its unfolded state, it works in conjunction with components such as the folding support frame rod B3 to provide stable support for the football goal frame, ensuring the structural integrity and safety of the goal during use and guaranteeing that the goal can withstand the impact of the football and other external forces. The folding support frame rod B3 is located obliquely symmetrically to the folding support frame rod A2, at the upper corner of the inner side of the football goal frame A1, providing support for the folding and unfolding of the upper part of the football goal frame in the goal-scoring direction. The folding support frame rod B3 is obliquely symmetrical to the folding support frame rod A2, located at the upper corner of the inner side of the football goal frame A1. Its main function is to provide folding and unfolding support for the upper part of the football goal frame in the goal-scoring direction. During folding, it works with the folding support frame rod A2 to allow the football goal frame to smoothly retract into a flat shape. When unfolded, it, together with the folding support frame rod A2, provides stable support for the football goal frame, especially playing a crucial supporting role for the upper structure of the football goal.

[0029] The football goal frame B4, in conjunction with the football goal frame A1, forms the overall frame structure of the football goal. Corresponding to the positions of the folding support frame rods A2 and B3, through-folding cavities A5 and B6 are respectively provided, offering space and guidance for the retraction and folding of the folding support frame rods A2 and B3, allowing for smooth folding and unfolding operations. Corresponding to the position of the folding support frame rod A2, the football goal frame B4 has a through-folding cavity A5, located on the football goal frame B4 at the position corresponding to the folding support frame rod A2, serving as the channel for the retraction and folding of the folding support frame rod A2. It provides a precise movement trajectory for the folding support frame rod A2, allowing it to move along a predetermined direction during folding and unfolding, avoiding deviation or jamming. Simultaneously, it also allows for effective storage of the folding support frame rod A2 after folding, making the football goal more compact and space-saving in the folded state.

[0030] Furthermore, the inner side of the football goal frame B4 is provided with a through folding cavity B6 at one end of the folding support frame rod B3, which allows the folding support frame rod B3 to extend and retract to fold and unfold the football goal frame. This provides a channel and guide for the extension and retraction of the folding support frame rod B3, ensuring that the folding support frame rod B3 can be operated smoothly during folding and unfolding, and that the folding support frame rod B3 can be effectively stored after folding.

[0031] Both the football goal frame A1 and the football goal frame B4 are integrally welded. The upper and lower outer ends of the football goal frame B4 are equipped with magnetic adsorption blocks 7, which magnetically attach the folding support frame rods A2 and B3 to the outside of the football goal frame B4 after folding. When the folding support frame rods A2 and B3 are folded, the magnetic adsorption blocks firmly attach them to the outside of the football goal frame B4. This not only prevents the folded frame rods from wobbling freely, ensuring the compactness of the overall structure, but also makes transportation and storage more convenient, eliminating concerns about the frame rods accidentally unfolding, and further saving storage space.

[0032] At the two symmetrically positioned corners on the inner side of the football goal frame A1, there are fixed posts 8, each with a connecting seat 9 at one end, providing a crucial connection foundation for the entire folding structure. This securely fixes the connecting seat 9 to the football goal frame A1, ensuring that it does not loosen or shift when subjected to the forces of the folding support frame rods A2 and B3. The presence of the connecting seat 9 guarantees smooth rotation of the frame rods without jamming or jamming. Furthermore, when the support is unfolded, it ensures a tight connection between the frame rods and the football goal frame A1, providing stable support for the football goal frame and guaranteeing the safety and reliability of the football goal during use. The structural design and manufacturing precision of the connecting seat 9 directly affect the movement flexibility and connection stability of the folding support frame rods.

[0033] Folding support door frame rods A2 and B3 are movably connected at one end to the connecting seat 9 via a pin. The other end of each rod passes through the through-folding cavities A5 and B6 on the football goal frame B4, and is equipped with a limiting plate 10. This limiting plate plays a crucial role in limiting the movement of the door frame rods. It prevents the door frame rods from excessively extending or retracting, ensuring precise positioning when folded and unfolded to the predetermined position, thus avoiding any impact on the normal use and storage of the football goal due to uncontrolled door frame rod positioning.

[0034] The lower ends of the football goal frame A1 and B4 are horizontally equipped with blocking support plates 11 to support the football goal frame on the ground. These plates 11 fully contact the ground, distributing the weight of the football goal, increasing friction with the ground, and preventing the football goal from sliding or tipping over during use. The lower ends of the goal frame A1 and B4 are equipped with omnidirectional casters 12 for moving and transporting the football goal frame after folding and unfolding. When it is necessary to move the football goal from one field to another, or to adjust its position within the field, simply push the football goal gently, and the omnidirectional casters 12 will flexibly turn, allowing the football goal to easily reach the designated position. Even after folding and unfolding, the omnidirectional casters 12 facilitate transport, allowing for quick transport of the football goal on both flat ground and slightly sloping surfaces.

[0035] Metal hooks 13 are evenly distributed within the inner cavities of the goal frame A1 and the football goal frame B4 for attaching the football net to the goal frame. The presence of these metal hooks 13 ensures the football net is securely installed on the goal frame. The evenly distributed design guarantees that the net is evenly distributed across the goal frame when under stress, preventing damage or detachment due to excessive localized force. In daily use, whether a player takes a powerful shot or the net is subjected to external forces such as wind, the metal hooks 13 ensure a tight connection between the net and the goal frame, providing a complete field facility for football.

[0036] Locking blocks 14 are provided on the bottom sides of both ends of the goal frame A1 and the football goal frame B4. These blocks provide a foundation for the installation and fixation of the tapered iron stakes 15, allowing the tapered iron stakes 15 to be tightly connected to the locking blocks 14 via threads. The material and structural strength of the locking blocks 14 must be able to withstand the tension and pressure generated when the tapered iron stakes 15 are screwed into the ground, as well as various external forces experienced by the football goal during use. This ensures that the football goal is firmly fixed to the ground. The tapered iron stakes 15, which are fixed to the ground after the football goal frame is unfolded, are threaded into the locking blocks 14. Screwing the tapered iron stakes 15 into the ground through the threads of the locking blocks 14 secures the football goal firmly to the ground. Especially during formal matches or high-intensity training, the football goal needs to maintain absolute stability. The tapered iron stakes 15, deeply embedded in the ground, provide strong anchoring force, preventing the football goal from shifting due to player collisions, football impacts, or other external forces, ensuring the safety and standardization of football.

[0037] Specifically, when using the football goal, to fold it, first operate the folding support frame rods A2 and B3. Folding support frame rod A2 rotates around the hinge point at the bottom corner of the inner side of the football goal frame A1, while folding support frame rod B3 rotates around the connecting seat 9 at the top corner of the inner side of the football goal frame A1 (a position obliquely symmetrical to folding support frame rod A2). During rotation, the other ends of folding support frame rods A2 and B3 extend and retract along the through-folding cavities A5 and B6 on the football goal frame B4, gradually shrinking the football goal frame into a flat shape. When folding support frame rods A2 and B3 are folded into place, the magnetic adsorption blocks 7 at the top and bottom of the outer side of the football goal frame B4 will firmly hold them in place, preventing the folded frame rods from wobbling and ensuring a compact overall structure. At this point, the football goal is folded, significantly reducing its footprint and making it easier to store and transport.

[0038] When unfolding the soccer goal, first release the magnetic adsorption block 7 from the folding support door frame rods A2 and B3. Then, reverse the operation of the folding support door frame rods A2 and B3, causing them to extend outward along the through folding cavities A5 and B6, while rotating around their respective hinge points or connecting seats 9. When the folding support door frame rods A2 and B3 unfold to the predetermined position, the limiting plate 10 will act as a limit to prevent the door frame rods from extending excessively and ensure accurate positioning of the door frame rods. At this point, the folding support frame rods A2 and B3, together with the goal frame A1 and B4, form a stable goal frame structure, providing stable support for the goal and ensuring its safety and reliability during use. When unfolded, the goal makes full contact with the ground through the horizontal blocking support strips 11 on the lower end faces of the goal frame A1 and B4, distributing the weight of the goal, increasing friction with the ground, and preventing slippage or tipping. The locking blocks 14 on the bottom sides at both ends, together with the threaded conical iron stakes 15, are screwed into the ground to further secure the goal firmly to the ground, in order to meet the stability requirements of formal matches or high-intensity training.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
