Description

Technical Field

[0001] This utility model relates to the field of amusement equipment technology, and in particular to a quick-release support frame for children's amusement equipment. Background Technology

[0002] As people's attention to children's education and entertainment continues to rise, children's playgrounds have become popular places favored by parents. Children's playground facilities are centered on providing diverse entertainment, games and sports activities, and are committed to creating a safe, fun and creative environment so that children can improve their life knowledge and health awareness while playing, thereby achieving the goal of auxiliary education. As the number of such facilities increases day by day, a quick-release support frame designed specifically for children's playground equipment has emerged.

[0003] The existing frames of children's amusement equipment mostly use welded steel pipes, flange connections, or multiple bolt connections. Welded steel pipes have high strength but are difficult to disassemble, and the equipment is prone to being scrapped when upgraded. Although flange connections can be disassembled, there are many bolts, installation is cumbersome, and exposed bolts pose a risk of collision. Multiple bolt connections are common in modular components, but they are prone to stress concentration in the pipes, which can easily lead to loosening and breakage after long-term use. Repeated disassembly and assembly will also aggravate thread wear. These traditional connection methods have obvious limitations in terms of flexibility, maintenance efficiency, and safety, which has driven the technological innovation of quick-release support frames.

[0004] While quick-release support frames for children's amusement equipment are driving industry development, issues remain at the connection points. On one hand, some quick-release structures are complexly designed with multiple clips or bolts, leading to cumbersome installation and time-consuming assembly, making them unsuitable for rapid on-site deployment. On the other hand, protruding metal inserts and bolt heads at the connection points lack rounded corners, posing a risk of scratches to children upon impact. Furthermore, many quick-release components have unpolished burrs, creating safety hazards. These issues require structural optimization and process improvement. Therefore, a quick-release support frame for children's amusement equipment is proposed to address these problems. Utility Model Content

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0041] Reference Figures 2 to 4 This utility model provides an embodiment of a quick-release support frame for children's amusement equipment, including a main frame 1. The main frame 1, as the core structure of the entire support frame, is made of high-strength lightweight alloy material, ensuring that it can withstand the impact force generated during children's amusement while reducing the overall weight, facilitating installation and movement. Three connecting mechanisms 2 are fixedly connected to one side of the main frame 1. The three connecting mechanisms 2 are evenly distributed along the main frame 1, providing a stable interface for subsequent connection of other components, ensuring the balance and stability of the structure. Connecting pipes 4 are fixedly connected to the other side of each of the three connecting mechanisms 2, serving as bridges connecting the main frame 1 to other components. A load-bearing mechanism 3 is fixedly connected to the other side of the main frame 1. The load-bearing mechanism 3 can store various emergency supplies. The connecting mechanism 2 includes a U-shaped plate 21, which is stamped from high-strength steel plate. Two toothed grooves 22 are opened on both sides of the U-shaped plate 21. An annular connecting part 23 is installed on the inner wall of the U-shaped plate 21. Two teeth 24 are provided on both sides of the annular connecting part 23. The teeth 24 adopt a trapezoidal structure design. This improves the stability and shear resistance of the connection. The inner wall of the annular connection 23 is slidably connected with a reinforcing component 25. The reinforcing component 25, through cooperation with the U-shaped plate 21 and the annular connection 23, further enhances the strength and stability of the connection, ensuring that it will not loosen during long-term use. The bearing mechanism 3 includes a transition plate 31, which serves as a transition structure between the main frame 1 and the frame 32. One side of the transition plate 31 is fixedly connected to one side of the main frame 1, and the other side is fixedly connected to the frame 32. The frame 32 is integrally molded from high-strength engineering plastic, which has good impact resistance and corrosion resistance, providing a safe storage space for emergency supplies. The inner wall of the frame 32 is slidably connected with a slider 34, which is made of wear-resistant material and has a smooth surface, ensuring smooth sliding within the frame 32 and facilitating quick access to emergency supplies. The inner wall of the frame 32 is fitted with a sealing strip 33, which is made of waterproof rubber and has good elasticity and sealing performance, effectively preventing rainwater, dust and other external factors from entering the interior of the frame 32 and protecting emergency supplies from damage.

[0042] Specifically, the children's amusement equipment uses a quick-release support frame with the main frame 1 as the core. It is made of high-strength lightweight alloy material, which has both impact resistance and lightweight characteristics. Three connecting mechanisms 2 are evenly distributed on one side of the main frame 1. Each connecting mechanism 2 is stably connected to the connecting pipe 4 through the cooperation of U-shaped plate 21, annular connecting part 23 and reinforcing component 25, which enhances the shear resistance and connection strength of the structure. On the other side, the frame 32 is connected to the transition plate 31 to form the load-bearing mechanism 3. The inner wall of the frame 32 is equipped with slider 34 and waterproof sealing strip 33, which can slide to store emergency supplies and achieve sealed protection. The overall structure is modularly designed to ensure convenient disassembly and assembly and safe use.

[0043] Reference Figures 1 to 3The reinforcing component 25 includes a stud 251, which is made of high-strength alloy steel and has undergone surface quenching treatment to improve hardness and wear resistance, ensuring that it will not deform or break during long-term use. The outer wall of the stud 251 is slidably connected to the inner wall of the annular connecting part 23, ensuring that the stud 251 can slide freely within the annular connecting part 23 for easy installation and disassembly. The outer wall of the stud 251 is threadedly connected to two fixing discs 252. The fixing discs 252 have a hexagonal design, which facilitates tightening and loosening operations using tools, improving installation and disassembly efficiency. The plate 21 has a positioning hole 253 inside. The position and size of the positioning hole 253 are designed to ensure that the stud 251 can be accurately inserted, providing precise positioning for the reinforcement component 25. One side of the annular connecting part 23 is in contact with one side of the main frame 1 to ensure tight connection and improve the overall stability of the structure. The other side of the annular connecting part 23 is fixedly connected to one side of the connecting pipe 4, ensuring that the connecting pipe 4 and the annular connecting part 23 form a whole and share the load. The outer wall of the tooth 24 and the inner wall of the tooth groove 22 engage, and the tightness between the tooth 24 and the tooth groove 22 is achieved. The screw 251 slides against the inner wall of the positioning hole 253, ensuring smooth sliding within the hole and facilitating the installation of the reinforcement component 25. One side of one fixing plate 252 contacts the inner wall of the U-shaped plate 21, and the other side of the fixing plate 252 contacts the inner wall of the annular connecting part 23. Through the interaction of the two fixing plates 252, the U-shaped plate 21 and the annular connecting part 23 are tightly fixed together, improving the strength and stability of the connection. The slider 34... The bottom and the top of the sealing strip 33 are in contact to ensure a good seal between the slider 34 and the frame 32, preventing rainwater, dust and other external factors from entering the interior of the frame 32. Both sides of the frame 32 are threaded with fixing posts 35. The outer wall of the fixing post 35 is threaded to the inner wall of the slider 34. By tightening and loosening the fixing post 35, the slider 34 and the frame 32 can be quickly fixed and separated, which is convenient for the storage and retrieval of emergency supplies. The fixing post 35 is T-shaped. The T-shaped design makes it easy for operators to use tools to tighten and loosen, improving operating efficiency.

[0044] Specifically, the reinforcing component 25 consists of a stud 251, two fixing discs 252, and a positioning hole 253. The stud 251 can slide within the annular connecting part 23 and is adapted to the positioning hole 253 to ensure convenient installation and disassembly. The hexagonal fixing disc 252 is threaded to the stud 251 and abuts against the inner wall of the U-shaped plate 21 and the annular connecting part 23 respectively to enhance the connection strength. The annular connecting part 23 is tightly connected to the main frame 1 and the connecting pipe 4. The teeth 24 and the grooves 22 engage to transmit the load. In the bearing mechanism 3, the slider 34 is fitted and sealed with the sealing strip 33. The T-shaped fixing column 35 is threaded to connect the slider 34 and the frame 32, which facilitates the storage and retrieval of materials and improves the operating efficiency.

[0045] Working principle: The U-shaped plate 21 is snapped onto the annular connecting part 23 at the end of the connecting pipe 4, and the teeth 24 are embedded in the tooth groove 22, thereby achieving the connection effect. At the same time, with the cooperation of the stud 251, the fixing plate 252 and the positioning hole 253 inside the U-shaped plate 21, the interaction of the two fixing plates 252 firmly fixes the annular connecting part 23 and the U-shaped plate 21. The two fixing plates 252 are located at the end of the outer wall of the stud 251, which greatly reduces the external protrusion and thus reduces the probability of scratches caused by children when they collide with it. The amplitude is reduced, and the connection method is simple and convenient, which makes the installation easy and the overall construction time is greatly reduced, thus greatly improving the installation efficiency. Rotating the fixed posts 35 on both sides of the frame 32 causes the slider 34 to separate from the frame 32, so that some emergency supplies can be put in so that effective emergency measures can be taken in case of accidents when children play. Moreover, due to the presence of the sealing strip 33, the slider 34 and the frame 32 are more tightly fitted when they are firmly fixed by the fixed posts 35, preventing rainwater and other external factors from affecting the emergency supplies stored inside the frame 32.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
