[0019] The external frame 14 is the basic structure of the entire fifth wheel, provides a mounting platform for internal components, and also bears the direct transmission of external loads. The frame is usually made of high-strength material to ensure sufficient rigidity and durability.

[0020] The surface of the external frame 14 is sprayed with an anti-corrosion coating to extend its service life.

[0021] The connecting guide is mounted on one end of the external frame 14 and is flexibly connected to an external device or structure through a rotating connection, allowing the fifth wheel to rotate freely within a certain range, thereby increasing the flexibility of use.

[0022] The fifth wheel can also be equipped with a locking device to fix the fifth wheel at a specific angle to prevent unwanted movement.

[0023] The telescopic cylinder 3 is installed on the inner side of the external frame 14, and the piston rod is driven to extend and retract by air pressure, thereby adjusting the position of the support slider 12. This allows the fifth wheel to adapt to different working requirements.

[0024] The guide rail base 15 is mounted on both sides of the inner wall of the external frame 14 to provide a stable sliding path for supporting the slider 12. The design of the guide rail base 15 needs to ensure that the slider remains straight during movement to avoid deviation or jamming.

[0025] In order to further improve the sliding performance, lubricant can be applied to the guide rail seat 15 .

[0026] The output end of the telescopic cylinder 3 is connected to a supporting slider 12, which is slidably arranged in a guide rail seat 15. The upper end of the supporting slider 12 is connected to an arched guide seat 10 through a connecting side plate 16. The end of the arched guide seat 10 contacts the inner edge of the guide rail seat 15, and the upper end of the arched guide seat 10 is connected to the support seat 5.

[0027] The inner edge of the guide rail seat 15 contacts the end of the arched guide seat 10 to ensure stability and accuracy during the sliding process.

[0028] The connecting side plate 16 connects the upper end of the supporting slider 12 and the arched guide seat 10 to ensure a stable connection between the two; and transmits the movement of the supporting slider 12 so that the arched guide seat 10 moves accordingly.

[0029] The arched guide seat 10 supports and connects the support seat 5 above, ensuring its stability and accuracy during movement.

[0030] The arched guide seat 10 is made of high-strength material and has sufficient rigidity and stability.

[0032] The support base 5 is mounted on the upper end of the arch guide base 10 to transmit the movement of the arch guide base 10 to the structure above. The support base 5 also plays the role of connecting the base connecting block 8. The support base 5 is usually made of high-strength material to ensure the reliability and stability of the connection.

[0033] The intermediate connecting seat 13 is installed on the upper surface of the base connecting block 8, which is connected to the rotating connecting support 6. The intermediate connecting seat 13 is connected to the rotating connecting support 6 by a hinged manner, allowing the rotating connecting support 6 to rotate freely within a certain range. The intermediate connecting seat 13 ensures that it can remain stable at different angles, realizes multi-angle adjustment, and improves convenience of use.

[0034] The middle connecting seat 13 uses a locking nut or a spring washer to ensure that it will not loosen during operation.

[0035] The connecting support 6 is rotated to connect the clamping plate 7, providing an installation position for the clamping plate 7, and the clamping plate 7 is connected to an external device or structure to achieve traction or support. The clamping plate 7 can ensure that it can remain stable at different angles.

[0036] Furthermore, the connecting guide seat includes a connecting bracket 1 and an adapter bracket shaft 2. The adapter bracket shaft 2 passes through a movable connecting seat provided in the external frame 14. The connecting bracket 1 is connected to the movable connecting seat.

[0037] The connecting bracket 1 is the main structural component of the connecting guide seat, used for fixed connection with external equipment or structure. It has high strength and rigidity to withstand external loads.

[0038] The adapter bracket shaft 2 is the rotating shaft of the connecting guide seat, which is used to realize the free rotation of the connecting bracket 1. It passes through the movable connecting seat in the external frame 14 to ensure that the connecting guide seat can rotate flexibly within a certain range.

[0039] Furthermore, the edge of the guide rail seat 15 is provided with an inner folding edge, and the inner folding edge contacts the side of the arched guide seat 10 .

[0040] The edge of the guide rail seat 15 is provided with an inner fold to increase stability during the sliding process; the inner fold is usually formed by precision processing to ensure that it is in close contact with the side of the arched guide seat 10. This helps to reduce the arched guide seat 10 from slipping out during the sliding process.
