Description

Technical Field

[0001] This utility model relates to the field of trampoline technology, and in particular to a windproof magnetic automatic separation trampoline. Background Technology

[0002] With the increasing demand for leisure and sports, trampolines, as equipment that combines entertainment and fitness, are widely used in outdoor settings such as family courtyards, parks, and children's playgrounds. In outdoor environments, trampolines need to meet the requirements of daily safe use, coping with complex weather (especially strong winds), and convenient installation and storage. Home users are gradually increasing their requirements for the difficulty of equipment assembly and the convenience of storage, while commercial operation scenarios are paying more attention to the structural stability and long service life of the equipment. This makes the performance design of trampolines in terms of "strong wind protection" and "easy assembly - stable and balanced structure" an important direction for industry research and development.

[0003] In existing technologies, outdoor trampolines first face structural safety issues in strong wind environments: traditional trampolines often use rigid connections between the protective netting and support components, lacking an adaptive separation mechanism. While this ensures protection during normal use, strong winds directly and continuously transmit the impact force of the airflow on the protective netting to the support components. If the wind force exceeds the load-bearing limit of the support components, it can easily cause damage such as metal fatigue and loosening of welds, not only shortening the equipment's lifespan but also potentially creating safety hazards in subsequent use, making it difficult to meet the needs of outdoor environments in harsh weather conditions. Secondly, existing trampolines also have shortcomings in balancing ease of assembly and structural stability: the horizontal support frame often uses bolt connections or splicing of single-specification pipe components. Bolted connections require specialized tools, are cumbersome, and are prone to corrosion, while splicing of single-specification pipe components requires additional clips, resulting in low assembly and disassembly efficiency and failing to fully meet the outdoor usage needs of different users. Structural optimization is urgently needed to solve these technical problems.

[0004] In response to this technical problem, this application proposes a windproof magnetic automatic separation trampoline. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a windproof magnetic automatic separation trampoline. Under normal use, the magnetic structure securely connects the protective net and support components, ensuring safety. In strong winds, the magnetic attraction automatically separates, preventing overload damage to the support components. Furthermore, the design of the large and small end round tubes and spring pins allows the trampoline to be quickly assembled and disassembled without tools, improving convenience and safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A windproof magnetic automatic separation trampoline includes a protective net. A rubber-coated iron base is fixedly connected to the upper outer wall of the protective net. A plastic part is installed inside the rubber-coated iron base. A protective rod is installed at the lower end of the plastic part. The protective rod is connected to a triangular foot bracket via a fixing component. A U-shaped ground tube is fixedly connected between the two sides of the triangular foot bracket. A large-end round tube is fixedly connected to the inner side of the triangular foot bracket. A hook spring is installed inside the large-end round tube. A small-end round tube is fixedly connected between the two sides of the large-end round tube. A fixing ring is installed at the other end of the hook spring. A jump cloth is fixedly connected to the inner side of the fixing ring.

[0008] Furthermore, a spring pin is provided inside the lower side of the guard rod, and the outer wall of the guard rod is located inside the upper side of the triangular foot bracket.

[0009] Furthermore, an iron block base is fixedly connected to the lower interior of the plastic part, and the outer wall of the iron block base is set at the upper end of the protective rod.

[0010] Furthermore, a strong magnet is fixedly connected to the upper end of the protective rod, and the outer wall of the strong magnet is disposed inside the lower side of the iron block base.

[0011] Furthermore, a first hole is provided on the upper outer wall of the triangular bracket, and the outer wall of the spring pin is disposed inside the first hole.

[0012] Furthermore, a second hole is provided on the outer wall of the large-end round tube, and one end of the hook spring is disposed inside the second hole.

[0013] Furthermore, a stepped frame is fixedly connected to the outer wall of the large-end round tube, and the outer wall of the stepped frame is located between the two U-shaped ground tubes.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, under normal use, the magnetic structure allows the protective netting to be securely connected to the protective support components, ensuring the normal functioning of the protection and preventing safety hazards for the user. However, when encountering strong winds, if the impact force of the airflow on the protective netting reaches the magnetic limit, the magnetic connection will automatically separate, preventing the protective netting from transmitting wind force to the support components. This significantly reduces the stress on the support components, fundamentally avoiding damage problems such as metal fatigue and loose welds caused by continuous overload. This significantly improves the structural safety and service life of the trampoline in harsh weather conditions, providing reliable protection for outdoor use.

[0016] 2. In this utility model, the trampoline utilizes an optimized design of large and small end tubes and spring pins to achieve quick fixing and convenient disassembly, while also ensuring structural stability. The horizontal support frame is assembled using the large and small end tubes; during assembly, simply fitting the small end tube into the large end tubes on both sides completes the initial assembly without additional tools. The fitting structure ensures a tight fit, effectively preventing frame wobbling and providing a stable horizontal support foundation for the trampoline. The guardrail and triangular foot brackets are fixed using spring pins for quick operation: pressing the spring pins during assembly causes them to retract. The entire process requires no complicated steps, saving assembly and storage time, and ensuring structural stability during use through precise component matching, significantly improving ease of operation and safety.

[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] Reference Figures 4-6 This utility model provides an embodiment of a windproof magnetic automatic separation trampoline, including a protective net 2. A rubber-coated iron base 11 is fixedly connected to the upper outer wall of the protective net 2. A plastic part 1 is provided inside the rubber-coated iron base 11. A protective rod 3 is provided at the lower end of the plastic part 1. A triangular foot bracket 4 is connected to the protective rod 3 through a fixing component. A U-shaped ground tube 15 is fixedly connected between the two sides of the triangular foot bracket 4. A large-end round tube 8 is fixedly connected to the inner side of the triangular foot bracket 4. A hook spring 9 is provided inside the large-end round tube 8. A small-end round tube 14 is fixedly connected between the two sides of the large-end round tube 8. A fixing ring 7 is provided at the other end of the hook spring 9. A jump cloth 5 is fixedly connected to the inner side of the fixing ring 7.

[0028] Specifically, in traditional structures, the lack of an effective automatic detachment mechanism between the protective net 2 and the protective rod 3 results in a rigid connection that cannot separate in time when wind force exceeds a safety threshold. This leads to problems such as metal fatigue and loose welds at the connection point of the protective rod 3. A novel magnetic quick-release fastener can be added to the connection between the protective rod 3 and the protective net 2. This fastener system consists of two parts: one side is a strong magnetic adsorption component installed on the edge of the protective net 2, using high-magnetic-force neodymium iron boron magnets whose magnetic parameters are precisely calculated to adapt to the protection needs of different trampoline sizes; the other side is an iron base fixed to the corresponding position on the protective rod 3, with a rust-proof surface to ensure stability during long-term outdoor use. When daily wind force or the impact force generated by normal trampoline use acts on the protective net 2, the magnetic adsorption component and the iron base will firmly adhere, maintaining a stable connection between the protective net 2 and the protective rod 3. This does not affect the closed protective function of the protective net 2 and can cope with normal stress conditions. When encountering strong winds, the impact of the airflow on the protective net 2 gradually increases. When the tension transmitted to the magnetic connection reaches the limit of the magnetic force of the magnetic structure, the magnetic component and the iron base will automatically separate. This separation process requires no manual operation and is achieved entirely by breaking the mechanical balance. At the moment of separation, the protective net 2 no longer forcibly transmits the wind force to the protective rod 3. The huge tension that was originally borne by the protective rod 3 disappears instantly, and the stress on the protective rod 3 is greatly reduced to a safe range, fundamentally avoiding metal fatigue and loosening of welds caused by continuous overload. Furthermore, a spring pin 13 is provided on the lower side for easy disassembly and installation.

[0029] Reference Figure 2 , Figure 3 and Figure 5 An iron block base 10 is fixedly connected to the lower interior of the plastic part 1, and the outer wall of the iron block base 10 is located at the upper end of the protective rod 3. A strong magnet 12 is fixedly connected to the upper end of the protective rod 3, and the outer wall of the strong magnet 12 is located at the lower interior of the iron block base 10. A second hole 17 is opened on the outer wall of the large-end round tube 8, and one end of the hook spring 9 is located inside the second hole 17. A step frame 6 is fixedly connected to the outer wall of the large-end round tube 8, and the outer wall of the step frame 6 is located between the two U-shaped ground tubes 15.

[0030] Specifically, the plastic part 1 and the protective rod 3 are connected via a magnetic structure: the iron base 10 fixed inside the lower side of the plastic part 1 has an outer wall that fits the upper space of the protective rod 3, and the strong magnet 12 at the upper end of the protective rod 3 is embedded inside the lower side of the iron base 10. Under normal use, the magnetic force keeps the two firmly connected, ensuring the protective function of the protective net 2; in the event of strong wind, the wind force overcomes the magnetic force, and the protective net 2 and the protective rod 3 automatically separate, preventing the protective rod 3 from experiencing metal fatigue or loosening of welds due to overload. The triangular bracket 4 is connected to the protective rod 3 by a spring pin 13, and the two large-end round tubes 8 are spliced ​​together by a small-end round tube 14 fitted onto the outer wall.

[0031] Reference Figure 1 , Figure 6 and Figure 7 A spring pin 13 is provided inside the lower side of the protective rod 3, and the outer wall of the protective rod 3 is provided inside the upper side of the triangular bracket 4. A first hole 16 is opened on the upper outer wall of the triangular bracket 4, and the outer wall of the spring pin 13 is provided inside the first hole 16.

[0032] Specifically, the spring pin 13 can be retracted by pressing, allowing the protective rod 3 to enter the upper interior of the first hole 16. After releasing, the spring pin 13 will come out from the first hole 16 to limit the movement. The head of the spring pin 13 can rotate and the outer side is reinforced to prevent accidental loosening.

[0033] Working Principle: The windproof magnetic automatic separation trampoline operates on a principle tailored to different usage scenarios. Through the coordinated efforts of its components, it achieves stable protection, strong wind protection, and convenient operation. Specifically: Under normal use, structural stability is ensured by a dual connection. Firstly, the upper end of the protective net 2 is fixed to the plastic component 1 via a rubber-coated iron base 11. The iron block base 10 inside the lower side of the plastic component 1 is adapted to the upper end of the protective rod 3. The strong magnet 12 (high-magnetic neodymium iron boron material) at the upper end of the protective rod 3 is embedded inside the lower side of the iron block base 10. Magnetic attraction firmly binds the two together. Simultaneously, the rubber-coated iron base 11 and the corresponding components of the protective rod 3 form an auxiliary connection. The magnetic attraction ensures a stable connection between the protective net 2 and the protective rod 3 to perform the function of closed protection. On the other hand, the support frame achieves stable support through multiple fixation. After the spring pin 13 on the lower side of the protective rod 3 pops out, it is inserted into the first hole 16 on the upper side of the triangular foot bracket 4. The head of the pin can be rotated to reinforce and prevent loosening. The large-end round tube 8 on the inner side of the triangular foot bracket 4 is spliced ​​together by the small-end round tube 14. The middle of the two sides of the triangular foot bracket 4 is fixed by the U-shaped ground tube 15. One end of the hook spring 9 on the large-end round tube 8 is fixed through the second hole 17, and the other end is connected to the jump cloth 5 through the fixing ring 7, providing elastic cushioning for the jump cloth 5 to ensure normal jumping. When in a strong wind environment, the automatic separation protection mechanism is activated. The impact force of the airflow on the protective net 2 is transmitted to the magnetic connection through the rubber-coated iron base 11 and the plastic part 1. When the impact force exceeds the magnetic attraction limit of the strong magnet 12 and the iron base 10, the mechanical balance is broken, the strong magnet 12 and the iron base 10 automatically separate, and the auxiliary magnetic attraction between the rubber-coated iron base 11 and the protective rod 3 is also disconnected. The protective net 2 no longer transmits the wind force to the protective rod 3, and the force on the protective rod 3 is reduced to a safe range, avoiding damage such as metal fatigue and loose welds. During assembly and disassembly, the protective rod 3 and the triangular bracket 4 can be assembled by pressing the spring pin 13 to retract it, inserting the lower end of the protective rod 3 into the upper part of the triangular bracket 4, and releasing it. The spring pin 13 pops out and locks into the first hole 16. Rotating the head of the pin can further reinforce it. When disassembling, press the spring pin 13 to disengage it from the first hole 16, and the protective rod 3 can be pulled out. The horizontal support frame is spliced ​​by fitting a small-end round tube 14 between two large-end round tubes 8, and the step frame 6 on the large-end round tube 8 is locked between the two U-shaped ground tubes 15 on both sides to enhance the stability of the frame.
