Description

Technical Field

[0001] This utility model relates to the field of soccer goal technology, specifically to an anti-eccentric folding soccer goal. Background Technology

[0002] As the core facility of football, the portability and stability of the goal have always been key design considerations. Traditional fixed football goals suffer from problems such as large footprint and inflexible storage, making them particularly unsuitable for limited spaces like primary schools, community venues, or temporary training scenarios. Therefore, folding football goal technology has emerged. Existing patent CN205268963U discloses a simple, small folding football goal frame, which achieves its folding function through a hinged structure combining a positioning crossbar, a positioning straight bar, and a rotating support rod. A movable sleeve slides along the positioning straight bar, and a pin secures the unfolded state. When folding, the pin is removed, allowing the support rod and rotating support rod to retract.

[0003] It mainly addresses issues such as the fixed occupation of the field by soccer goals and the risk of collisions between students during breaks in primary school physical education classes; compared to welded fixed goals, it can be folded to reduce its volume and is easy to store after class.

[0004] However, this structure has significant drawbacks in terms of structural stability, impact resistance, and ease of operation. It is particularly prone to displacement or deformation when subjected to non-perpendicular impact forces (i.e., off-center loading), affecting its safety and lifespan. Specifically, this manifests in the following ways:

[0005] The existing folding soccer goal has a complex structure and redundant operation. The folding process requires the operation of multiple independent components in steps: first, the pin at the bottom of the positioning rod is removed; then the sleeve is moved; and finally, the rotating support rod and the support pole are folded together. This process involves at least three action points, making it inconvenient for non-professionals to operate. In addition, there are too many hinge points, up to four on one side. The accumulated gaps between these points reduce the overall rigidity of the goal frame, making the goal prone to multi-stage lever deformation when hit by a shot, requiring frequent adjustments.

[0006] Existing folding soccer goals have weak resistance to eccentric loads, and the base support structure (i.e., the positioning rod and the moving sleeve) lacks an axial limiting mechanism. When the ball hits the side net of the goal frame, the impact force is decomposed into vertical and horizontal components. The horizontal component pushes the base support rod to slide axially, causing the entire goal frame to tilt. In addition, the stabilization method relying on its own weight and ground friction fails on grass or slippery fields, requiring additional counterweights. For example, the high-stability folding soccer goal disclosed in prior art CN220736119U uses a counterweight box design, but this increases the burden of handling.

[0007] Traditional ball nets are directly tied to the poles with ropes. When the rope tension is uneven, it generates asymmetrical tension, which further amplifies the off-center load effect. The tying point is concentrated at the top of the goal frame (positioning crossbar). When a shot hits the net, it creates an overturning moment with the base as the fulcrum, causing the goal to tip forward. This type of net fixing method exacerbates the risk of imbalance. For a specific case, please refer to the Grimsby goalkeeper accident in the English League Two. Utility Model Content

[0008] The problem this invention aims to solve is that existing folding soccer goals are prone to axial slippage of the base support rod when subjected to non-vertical impact loads, leading to goal tilting or overturning. These problems also result in cumbersome operation, uneven net tension, poor stability, inconvenience, and safety hazards. The invention provides a simplified structure, convenient operation, strong resistance to off-center loads, high connection stability, and easy portability and storage of an anti-off-center load folding soccer goal. This improves safety, extends service life, and adapts to the flexible use requirements of various training scenarios.

[0009] To address the aforementioned problems, this utility model provides an anti-eccentric load folding soccer goal, comprising a goal frame support rod and a base support rod intersecting the goal frame support rod longitudinally. The bottom end of the goal frame support rod is fixedly sleeved within an anti-eccentric load limiting component and is rotatably separated from it. The base support rod is disposed on the upper end of the anti-eccentric load limiting component. The anti-eccentric load limiting component has concave structures at both ends to axially limit the ends of the base support rod. A movable connecting kit is fixedly sleeved on the outer periphery of the anti-eccentric load limiting component. A pin passes sequentially through the movable connecting kit and the limiting hole on the base support rod to allow the base support rod to be folded vertically.

[0010] Preferably, the anti-eccentric load limiting component has a semi-bottle structure, with an upwardly protruding threaded connecting sleeve fixed at the inner end of the bottle mouth structure. The bottom of the base support rod is threaded into the threaded connecting sleeve to form a rotational separation connection, resisting thread rotation caused by vibration, providing reliable axial load-bearing and torsional performance, and preventing loosening due to impact. The outer edge of the threaded connecting sleeve is evenly distributed with threaded positioning teeth.

[0011] Preferably, the anti-eccentric load limiting component has multiple square cavities at the inner end of its bottle body structure. Compared with existing counterweights such as solid metal blocks, the square cavities of the anti-eccentric load limiting component reduce the weight of the component while ensuring strength. The concave structure is an anti-eccentric load limiting block that is fixedly set on the upper end of the inner edge of both sides of the bottle body structure and extends inward. The anti-eccentric load limiting block has a U-shaped structure, forming a concave constraint, which provides reliable axial limiting during eccentric loading and prevents the rod from slipping.

[0012] Preferably, the movable connection kit comprises three parts: a left propeller-shaped connecting section and a right propeller-shaped connecting section at both ends, and a U-shaped load-bearing section that fixes the two together. A gap is provided between the left and right propeller-shaped connecting sections, and the door frame support rod and the base support rod are disposed within this gap. The integrated design of the propeller-shaped connecting section and the U-shaped load-bearing section of the movable connection kit replaces the traditional multi-hinge structure, reducing most moving parts, lowering the risk of loosening and wear, and eliminating the hidden danger of joint loosening.

[0013] Preferably, the left propeller-shaped connecting section and the right propeller-shaped connecting section are provided with a clamping groove at their center. The upper U-shaped protrusion of the anti-eccentric load limiting block extends into the clamping groove and abuts against it. The concave U-shaped limiting block and the clamping groove in the movable connecting kit are tightly fitted to form a three-dimensional constraint, which can further effectively limit the axial slippage of the base support rod when subjected to lateral impact, avoid overall overturning or displacement, and significantly improve the stability and safety at the moment of impact.

[0014] Preferably, both the door frame support rod and the base support rod are fitted with adhesive sleeves. The outer edge of the adhesive sleeve is provided with an obliquely extending net insert plate. The inner edge of the net insert plate is provided with a vertically penetrating net slot cavity. The net passes through the net slot cavity, and the net tension is evenly distributed along multiple points to avoid local stress concentration, reduce the overturning moment caused by eccentric loading, and improve overall stability.

[0015] Preferably, both the door frame support rod and the base support rod have a U-shaped structure, and the height of the folded base support rod is lower than that of the door frame support rod. This results in a smaller folded volume, making it easier to carry and store; the folding / unfolding action is intuitive and simple, requiring no multi-point disassembly or assembly.

[0016] Compared with the prior art, the present invention achieves the following beneficial technical effects:

[0017] This utility model makes folding operation simpler. It adopts a single-point operation, which only requires plugging and unplugging the pin to complete the folding or unfolding of the base support rod. The base support rod can be quickly folded and unfolded by "pulling out to fold and plugging in to use" through the pin and the movable connecting kit. There is no need to repeatedly install and disassemble multiple hinges or moving sleeves, which greatly reduces the operator's steps and time costs.

[0018] This utility model utilizes the cooperation of a pin and a movable connecting kit. The pin passes through the movable connecting kit and the limiting hole on the base support rod in sequence, thereby allowing the base support rod to be folded up and down and connected to form a radial limit. The anti-eccentric load limiting component has concave structures at both ends, thereby axially limiting both ends of the base support rod and completely blocking the axial displacement caused by horizontal impact force.

[0019] This utility model adopts an integrated slot for fixing the net. Through the upper and lower through slot structure that combines the adhesive sleeve and the inclined net insert plate, it ensures that the tension distribution of the net is uniform when it is under force, and is no longer concentrated at the top fixing point, thereby further reducing the overturning moment generated when shooting.

Detailed Implementation

[0028] The present invention will be further explained below with reference to the accompanying drawings and embodiments.

[0029] Example 1: Overall Structure and Folding and Unfolding Process: As shown Figure 1 , Figure 2 , Figure 6 As shown, the anti-eccentric load folding soccer goal of this embodiment includes:

[0030] The lower end of the door frame support rod 1 is sleeved and rotated inside the anti-eccentric load limiting component 3;

[0031] The base support rod 2 has its upper end fitted onto the upper opening of the anti-eccentric load limiting component 3;

[0032] The anti-eccentric load limiting component 3 has concave U-shaped anti-eccentric load limiting blocks 304 at both ends, which are used to limit the axial sliding of the base support rod 2.

[0033] The movable connecting kit 4 is fixed to the outer periphery of the limiting component 3, and forms left and right propeller-shaped connecting sections 401 and 402 at its left and right ends respectively, as well as a U-shaped bearing section 403 in the middle.

[0034] The pin 7 can pass through the limiting hole on the movable connecting kit 4 and the base support rod 2 to realize the vertical folding and locking of the rod 2.

[0035] Expanded state: such as Figure 3 As shown, after the pin 7 is pulled out, the base support rod 2 falls from the limiting block 304 to the fully extended position under the action of gravity; at this time, after the pin 7 is put back in, the kit 4 cooperates with the limiting hole to form a radial limit, and the upper and lower positions of the base support rod 2 are fixed and stable.

[0036] Folded state: such as Figure 5 As shown, pull out the pin 7 and lift the base support rod 2 upward. The rod 2 retracts to be parallel to the door frame support rod 1 under the concave guidance of the limiting block 304. Then the pin 7 is re-inserted to complete the folding and locking. The overall thickness is significantly reduced, making it easier to transport and store.

[0037] Example 2 Anti-eccentric load limiting component 3, such as Figure 6 , Figure 7 As shown, the limiting component 3 adopts a half-bottle structure:

[0038] The inner end of the bottle mouth is provided with a threaded connecting sleeve 301, and the bottom threaded part of the base support rod 2 can be screwed to it to realize a rotary separation connection; the outer edge of the threaded connecting sleeve 301 is provided with threaded positioning teeth 302, which can prevent loosening under vibration or impact conditions.

[0039] Multiple square cavities 303 are opened on the inner side of the bottle to reduce the weight of the components; the U-shaped limiting blocks 304 extending inward from the upper end of the inner edge on both sides form a reliable axial limit on both ends of the base support rod 2, which can withstand the horizontal component force during lateral impact and prevent the rod from axially slipping.

[0040] Example 3: Active connecting kit 4 and limiting fit, such as Figure 1 , Figure 2 and Figure 4As shown, the movable connection kit 4 is manufactured as a single unit consisting of a left propeller-shaped connection section 401, a right propeller-shaped connection section 402, and a central U-shaped load-bearing section 403. A gap 404 is left between the left and right propeller-shaped connection sections, and the door frame support rod 1 and the base support rod 2 are both placed in this gap and cooperate with the clamping groove 405 opened in the kit through the anti-eccentric load limiting block 304.

[0041] The groove 405 is the opening at the center of the propeller-shaped connecting section. The upper U-shaped protrusion of the anti-eccentric load limiting block 304 extends into the groove 405 and abuts against it. The concave U-shaped limiting block 304 and the groove 405 in the movable connecting kit 4 fit tightly together to form a three-dimensional constraint, which can further effectively limit the axial slippage of the base support rod when subjected to lateral impact, avoid overall overturning or displacement, and significantly improve the stability and safety at the moment of impact.

[0042] Example 4: Net fixing method, such as... Figure 1 and Figure 3 As shown, both the door frame support rod 1 and the base support rod 2 are fitted with adhesive sleeves 5, and the outer edge of the sleeve extends obliquely outward to form a net insert plate 501. The inner edge of the insert plate 501 has a vertically penetrating net slot cavity 502. After the edge of the net 6 is inserted into the slot, its tension can be evenly distributed at multiple points, avoiding the asymmetrical force caused by the traditional top-concentrated binding and reducing the risk of overturning.

[0043] Example 5, U-shaped rod and portability, such as Figure 5 As shown in this embodiment, both the door frame support rod 1 and the base support rod 2 are U-shaped cross-section structures, which ensures the necessary strength and rigidity, and also ensures that the overall height of the base support rod 2 is lower than that of the door frame support rod 1 after folding, thereby minimizing the overall thickness of the folded structure and making it easy to carry with both hands or put into a storage bag.

[0044] In summary, the anti-eccentric folding soccer goal shown in the above embodiments achieves advantages such as simple structure, convenient folding, resistance to lateral impact, and long-term stability through technical solutions such as threaded separation connection, three-dimensional fit of concave limiting block / groove, integrated movable kit, and force-equalizing net slot.
