DETAILED DESCRIPTION
[0022] The utility model will be further explained in detail below in combination with the drawings.
[0023] The utility model discloses a kind of amusement facilities connecting structures, as shown in Fig. Figs. 1 to 3 It includes hollow connecting column 1, connecting block 2, the connecting block 2 is provided with the connecting end 3 of mutual matching plug-in with connecting column 1, the connecting end 3 is not less than two, the connecting block 2 can be simultaneously connected with less than two connecting column 1;The connecting end 3 includes connecting protrusion 31, the outer edge of the connecting end 3 forms protection structure 4, the protection structure 4 can block the gap generated when connecting column 1 and connecting block 2 cooperate, avoid children with contact;The cross section of connecting column 1 is fan-shaped, the fan-shaped cross section has higher cross section modulus along radial direction, can effectively resist bending moment, and arc portion can disperse pressure, reduce local stress concentration, and radial edge can be used as reinforcing rib to improve rigidity;Connecting column 1 is provided with groove 11 close to edge, the groove 11 separates connecting column 1 into plug-in part 13 and reinforcing part 12 close to two sides, the edge of connecting block 2 is adaptively set in groove 21, the setting of groove 11 and groove 21 makes that arc curved surface is wave-shaped curved surface, can more effectively resist bending moment and increase rigidity, the groove 21 separates connecting protrusion 31 into reinforcing block 311 and plug-in block 312, the reinforcing block 311 and plug-in block 312 are matched with reinforcing part 12 and plug-in part 13 respectively, contact forms closed box section, and the stability of connecting end 3 cooperation is improved by increasing torsional cross section modulus and improving torsional rigidity.
[0024] Further improve, the inner cavity of plug-in part 13 is uniformly provided with reinforcing partition 131.The setting of reinforcing partition 131 forms similar "honeycomb-like" internal support, significantly improves the bending resistance of plug-in part 13, delays the plastic deformation caused by structural fatigue.
[0025] Furthermore, the connecting protrusion 31 is provided with a spacer groove 3121 that is adapted to the reinforcing partition 131. During the installation process, the spacer groove 3121 creates a physical clearance space between the reinforcing partition 131 and the connecting protrusion 31, thus avoiding structural interference between the two. The width of the spacer groove 3121 is greater than the width of the reinforcing partition 131, which greatly reduces the fitting accuracy requirements when the components are connected, thereby effectively mitigating the impact of processing errors on assembly.
[0026] In this embodiment, the protective structure 4 has different implementations, which will be described below with reference to the accompanying drawings.
[0027] Example 1: Refer to Fig. 2 , 4 As shown, the protective structure 4 is a protective protrusion 6 formed by extending upward from the outer edge of the connecting end 3. The outer surface of the protective protrusion 6 is an arc-shaped surface with no sharp edges, and the arc-shaped surface structure is not easy to snag clothing or other objects. When children play, they are more likely to come into contact with the outer surface of the connector. The protective protrusion 6 is a protrusion formed by extending from the outer edge of the connecting end 3, which covers the connecting post 1 from bottom to top and covers the gap formed by the insertion and cooperation between the connecting post 1 and the connecting block 2 from the outside. This makes the easily accessible outer gap covered by the protective protrusion 6, preventing children from being injured by contact when playing.
[0028] Example 2: Refer to Figs. 5 to 6 As shown, the protective structure 4 consists of a protective sleeve 5 covering the outer periphery of the connecting protrusion 31. The outer edge of the protective sleeve 5 extends upward and downward to form an outer edge protrusion 521 covering the side surfaces of the connecting post 1 and the connecting block 2. The outer surface of the outer edge protrusion 521 is an arc-shaped surface. The outer edge protrusion 521 of the protective sleeve 5 simultaneously covers the connecting post 1 near the top and the connecting block 2 near the bottom from the outside, so that the gap generated at the connection between the connecting post 1 and the connecting block 2 is covered inside the protective sleeve 5 and not exposed to the outside. This makes it difficult for children to access, preventing children from accidentally getting their clothes caught in the gap and falling while playing, and also preventing sharp gaps from pinching or scratching children's delicate skin.
[0029] Further improvements include a downward extension of the inner edge to form a limiting protrusion 512, and a connecting groove 322 that is adapted to the connecting end 3 and the limiting protrusion 512. When the limiting protrusion 512 and the connecting groove 322 are connected, the connecting groove 322 will restrict the sliding of the protective pad 5 on the contact surface, so that the protective pad 5 can be stably set on the connecting protrusion 31 and will not be pried out by children when playing.
[0030] Furthermore, the protective sleeve 5 includes a rigid plastic frame 51, with a flexible covering layer 52 covering its outer periphery. The rigid plastic frame 51 provides inner support, and when the limiting protrusion 512 engages with the annular slot, the rigid plastic frame 51, with its strong resistance to deformation, ensures the annular slot is stably fixed within it and will not easily come loose. The flexible covering layer 52 provides flexible protection on the outer layer, preventing children from being injured by bumps and knocks while playing, protecting children while also reducing its own impact and increasing its service life.
[0031] Furthermore, the flexible covering layer 52 is made of elastic rubber. This elastic rubber absorbs vibrations, reducing the impact on the connection point when children play, increasing the stability of the contact surface between the connecting block 2 and the connecting post 1, preventing the connecting block 2 and the connecting post 1 from loosening due to vibrations and impacts from children's play, preventing connection failure and injury to children, and protecting children's safety.
[0032] like Fig. 2 As shown, the connecting post 1 has a pre-embedded screw hole 14 on its inner side, and the connecting block 2 has a corresponding connecting hole 22. When the connecting block 2 and the connecting post 1 are inserted into each other, the positions of the pre-embedded screw hole 14 and the connecting hole 22 coincide, allowing for reinforcement by screwing in the pre-embedded screw. This ensures a reliable fit between the connecting block 2 and the connecting post 1, preventing loosening. Furthermore, the pre-embedded screw hole 11 is located on the inner side of the connecting post, ensuring the screw is flush against the interior of the structure after installation, effectively preventing children from contacting it during play and reducing the risk of bumps and knocks.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
