[0032] 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.

[0033] For reference as follows Figures 1-8 The present invention will be described as follows:

[0034] Example: A connection device for a non-powered amusement facility includes a connector body 1, with U-shaped holding parts 2 on the left and right sides of the connector body 1, and a shaft hole 3 penetrating the connector body 1 and the holding parts 2 in the front-back direction. A fixed shaft 4 is connected in the shaft hole 3. The fixed shaft 4 is made of metal material and has high mechanical strength, and is used to fix the connector to the external frame structure and share the load.

[0035] The main body 1 of the connector is a block structure, serving as the force-bearing center and assembly base of the entire connecting device. The main body 1 of the connector has two shaft holes 3, which are spaced apart on the left and right sides. The shaft holes 3 penetrate the front and rear end faces of the main body 1 of the connector.

[0036] The left and right sides of the connector body 1 are used to connect the amusement facility components to be connected, while the front and rear sides provide assembly support surfaces for the holding part 2.

[0037] Two holding parts 2 corresponding to the shaft hole 3 are respectively connected to the front and rear sides of the connector body 1. The holding parts 2 are provided with through holes 5 coaxial with the shaft hole 3.

[0038] The holding part 2 has a U-shaped structure and there are four of them. They are respectively set with two shaft holes 3 on the front and rear sides of the connector body 1. That is, each side of the connector body 1 is connected to two holding parts 2, and the position of the holding part 2 corresponds one-to-one with the shaft hole 3.

[0039] To enhance structural strength and meet load-bearing requirements, the middle section of the holding part 2 is thickened, and a through hole 5 is located in the middle of the holding part 2. The axis of the through hole 5 coincides with the axis of the corresponding shaft hole 3 on the main body of the connector, providing a channel for the bolt 6 to pass through.

[0040] The inner wall of the shaft hole 3 is provided with internal threads for forming a threaded connection with the bolt 6.

[0041] It also includes bolt 6, which passes through the through hole 5 and is threadedly connected to the shaft hole 3. Bolt 6 serves as a fastening element between the holding part 2 and the connecting body 1. Its shank can pass through the through hole 5 of the holding part 2 and be threadedly engaged with the shaft hole 3 of the connecting body 1, thereby firmly fixing the holding part 2 to the connecting body 1.

[0042] Bolt 6 has through holes 7 extending through both ends of its axial direction, and fixing shaft 4 passes through the through holes 7 of two coaxially corresponding bolts 6.

[0043] During the assembly stage, firstly, place the four holding parts corresponding to the shaft holes 3 on the front and rear sides of the main body 1, so that the through holes 5 of the holding parts 2 are coaxially aligned with the shaft holes 3 of the main body 1; then, pass the bolts 6 through the through holes 5 of the holding parts 2, screw them into the shaft holes 3 of the main body 1 and tighten them. Through the threaded engagement of the bolts 6 and the shaft holes 3, a rigid connection between the holding parts 2 and the main body 1 is achieved; finally, pass the fixing shaft 4 through the through holes 7 of the two bolts 6 connected to the opposite holding parts 2 on the same axis to complete the assembly of the entire device.

[0044] In use, the two amusement facility components to be connected are fixedly connected to the holding parts 2 on the left and right sides of the main body 1 of the connector. Specifically, the components can be clamped and fixed by setting fastening structures (such as bolts, buckles, etc.) in the U-shaped groove of the holding part 2. At the same time, the two fixing shafts 4 through the holes 7 of the through bolts 6 are connected and fixed to the external frame structure, so that the main body 1 of the connector can obtain external support through the fixing shafts 4.

[0045] During the operation of a non-powered amusement rides, the main body 1 of the connector is situated between two connected components and must withstand various loads, including the weight of the components themselves and dynamic loads from user movements. Traditional U-shaped holding connectors rely solely on their connection with the components to transmit force, which can easily lead to loosening due to concentrated loads. In this device, two fixed shafts 4 are rigidly connected to the main body 1 of the connector via bolts 6 and fixed to the external frame structure. This allows the load borne by the main body 1 of the connector to be transferred to the external frame structure through the fixed shafts 4. This design disperses the load originally concentrated on the main body 1 of the connector and the holding part 2, reducing the stress on individual connection points and effectively lowering the risk of displacement or loosening of the holding part 2 due to excessive load, thus significantly enhancing the overall stability of the amusement ride connection.

[0046] The device is composed of independent components such as the main connector 1, the holding part 2, the fixing shaft 4, and the bolts 6. Each component has a clear function and is easy to manufacture. Compared with an integrated structure, the modular design facilitates the production, testing, and replacement of individual components, reducing manufacturing difficulty and maintenance costs. If a component is damaged, it is not necessary to replace the entire connector; only the corresponding component needs to be replaced.

[0047] The front and rear sides of the connector body 1 are respectively provided with connecting rings 8 that are coaxial with the shaft hole 3. The holding part 2 is provided with connecting grooves 9 that are adapted to connect with the connecting rings 8. The diameter of the connecting groove 9 is larger than the diameter of the through hole 5, ensuring that the bolt 6 can pass smoothly through the through hole 5 and engage with the shaft hole 3, while providing space for the connecting rings 8. During assembly, the connecting rings 8 are embedded in the connecting grooves 9, and the two form a radial limiting fit, effectively filling the assembly gap between the holding part 2 and the connector body 1.

[0048] This embedded mating structure significantly enhances connection stability: traditional axial fastening with only bolts 6 is prone to slight movement of the holding part 2 along the bolt axis due to vibration. However, the radial limiting of the connecting ring and the connecting groove can restrict the radial displacement of the holding part 2, making the holding part 2 fit more tightly with the main body 1 of the connector, reducing stress concentration points, and avoiding the risk of loosening that may occur with single bolt fastening.

[0049] The connecting groove 9 has a regular polygonal structure, and the shape of the connecting ring 8 is adapted to the polygonal outline of the connecting groove 9. This structure has the dual functions of preventing rotation and adjusting angle.

[0050] The edges and corners of the regular polygon form a rigid limit. When the connecting ring 8 is inserted into the connecting groove 9, the polygonal contours interlock, effectively preventing the holding part 2 from rotating relative to the connecting body 1 around the axis of the shaft hole 3. This design solves the problem of circumferential loosening that is easily caused by traditional circular fits or single bolt tightening, ensuring that the holding angle of the holding part 2 on the amusement facility components remains stable and avoiding connection failure due to rotation.

[0051] The regular polygonal structure allows for graded adjustment of the angle of the holding part 2 by changing the interlocking edges of the connecting ring 8 and the connecting groove 9. For example, if the connecting groove 9 is a regular hexagon, a stable assembly angle can be formed every 60 degrees of rotation. Users can select the appropriate interlocking position to fix the holding part 2 according to the installation requirements of the parts to be connected, without the need for additional processing of connectors with different angles, thus improving the versatility and installation flexibility of the device.

[0052] One end of the bolt 6 is connected to a cover 10, which is attached to one end of the bolt head. The cover 10 is annular, with one end closed. The cover 10 is designed to fit into the bolt 6. The closed end of the cover 10 has an opening 11 for the fixed shaft 4 to pass through. The cover 10 prevents external dust, rainwater, debris, etc., from entering the through hole 7 and the shaft hole 3.

[0053] The holding part 2 has two side arms that hold the component. One side arm of the holding part 2 has a threaded hole 12, and the other side arm of the holding part 2 has a connecting hole 13 corresponding to the threaded hole 12. The two side arms of the holding part 2 clamp and fix the component by bolts. The bolts pass through the connecting hole 13 and the component between the two side arms and the threaded hole 12 to form a fixed connection.

[0054] A first protruding post 14 is provided on the inner side of one side arm of the holding part 2, and a threaded hole 12 is provided on the first protruding post 14. Compared with directly opening a threaded hole on the side arm, the first protruding post 14 increases the effective thread length of the threaded hole 12, improves the engagement depth between the bolt and the threaded hole, and makes the bolt tightening force more evenly transmitted to the side arm, avoiding thread stripping due to insufficient thickness of the side arm, and enhancing the load-bearing capacity of the connection.

[0055] On the inner side of the other arm of the holding part 2, there is a protruding second protrusion 15, and a connecting hole 13 is provided on the second protrusion 15. The second protrusion 15 is arranged opposite to the first protrusion 14, and the connecting hole 13 passes through the second protrusion 15 and is coaxial with the threaded hole 12. The double protrusion structure changes the contact between the holding part 2 and the component from surface contact to protrusion point contact, increasing the pressure at the contact point and improving the clamping effect.

[0056] The two side arms of the holding part 2 have protruding positioning protrusions 16 on their facing surfaces. The component between the two side arms has positioning grooves corresponding to the positioning protrusions 16. When the holding part 2 clamps the component, the positioning protrusions 16 are embedded in the positioning grooves, forming a mechanical limit. This structure can enhance the connection stability from two dimensions.

[0057] The engagement of the positioning protrusion and the groove can limit the displacement of the component along the length of the side arm of the holding part 2, and prevent the component from slipping out of the U-shaped groove of the holding part 2 under vibration or external force.

[0058] The combination of the protrusion and the groove further restricts the radial sway of the component within the holding part 2, keeping the relative position of the component and the holding part 2 fixed, ensuring more stable force transmission, and reducing local stress concentration caused by component displacement.

[0059] The outer wall of the bolt head end of bolt 6 is provided with a structure to increase friction, making it easier to rotate bolt 6. This structure increases the contact friction between the operator's hand or tool and the bolt head, making it easier for the operator to apply force when tightening or loosening bolt 6. It enables the rapid assembly and disassembly of bolt 6 without the need for special tools. Especially in scenarios where installation space is limited on amusement facilities, it can significantly improve construction efficiency and reduce operational difficulty.

[0060] 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 spirit and principles of the present utility model should be included within the protection scope of the present utility model.
