DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the upper part is described as the upper part below). All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Figure 2 above is described as above).

[0016] Please refer to Figures 1-3, this application provides a technical solution: an adjustable towing hitch, including an intermediate connection frame 2, on which a towing guide seat is provided. The towing guide seat includes a vertical guide sleeve 1 and an adjustment guide frame 9. The vertical guide sleeve 1 is located on one side of the intermediate connection frame 2. The adjustment guide frame 9 is sleeved inside the vertical guide sleeve 1 and is connected by a through-pin shaft 3. The lower end of the adjustment guide frame 9 is connected to a guide frame connection support.

[0017] The intermediate connection frame 2 is the main structure of the entire towing hitch, bearing all components and connecting to the vehicle or other structures through multiple connection points on it. The middle cross brace enhances the overall structural stability and torsional resistance, preventing deformation during high-load towing. The towing guide seat is mainly responsible for adjusting the towing height. The vertical guide sleeve 1 is fixed on one side of the intermediate connection frame 2, providing guidance and support for the adjustment guide frame 9 and only allowing vertical movement. The adjustment guide frame 9 can slide up and down along the vertical guide sleeve 1 and is locked at an appropriate height through the through-pin shaft 3 to meet the height requirements of different towed objects. The through-pin shaft 3 is a connecting piece between the adjustment guide frame 9 and the vertical guide sleeve 1, fixing the adjustment guide frame 9 after it is adjusted to the required height to prevent it from moving on its own due to vibration during towing, and connecting to an external towed object through the guide frame connection support.

[0018] Before towing, first manually adjust the adjustment guide frame 9 to an appropriate position according to the height of the towed object, and use the through-pin shaft 3 to fix the adjustment guide frame 9 at the selected height. After completing the height adjustment, connect the towed object to the adjustment guide frame 9 to ensure a firm connection. During towing, the intermediate connection frame 2 and the towing guide seat jointly bear the weight of the towed object while maintaining the stability of the towing system.

[0019] An auxiliary connection seat 4 is also provided on the outside of the intermediate connection frame 2. The auxiliary connection seat 4 includes connection ear plates 12, connection pads 10, and fixing bolts 11. The connection ear plates 12 are located on both sides of the connection pad 10. The through holes provided on the connection pad 10 correspond to the fixing bolts 11. The fixing bolts 11 are connected to the intermediate connection frame 2 through the through holes provided on the connection pad 10. At least five through holes corresponding to the fixing bolts 11 are provided on one side of the intermediate connection frame 2.

[0020] The auxiliary connection seat 4 is provided with additional connection points to enhance the connection stability between the traction seat and the towing equipment or vehicle, so as to facilitate flexible adjustment according to different use environments and requirements. The connection ear plates 12 are located on both sides of the connection pad 10, with preset holes for bolts or pins to pass through to fix the towing equipment or vehicle; the connection ear plates 12 provide a larger contact area, thereby increasing the stability of the connection, especially when bearing heavy loads or encountering uneven roads; the connection pad 10 is the main component of the auxiliary connection seat 4, located between the connection ear plates 12, and directly connected to the middle connection frame 2; the fixing bolt 11 is a fastener used to fix the connection pad 10 to the middle connection frame 2, and is usually made of high-strength material to withstand the tension and vibration during the towing process.

[0021] Furthermore, two middle cross braces are arranged in the middle of the middle connection frame 2 .

[0022] The middle cross brace, by connecting the two sides of the frame, forms a more stable structure, similar to the truss principle in bridge engineering, which can effectively resist lateral and longitudinal torsional forces, keep the shape of the frame stable, and enhance the stability and rigidity of the entire fifth wheel structure. The cross brace is usually made of high-strength material, such as steel, and they span the width of the middle connecting frame and are located in the center of the frame.

[0023] Furthermore, the middle connection frame 2 is also connected to a towing group 13 .

[0024] Furthermore, the towing group 13 includes a towing guide frame 5 , a socket and a towing connection sleeve 6 . The inner side of the towing guide frame 5 is connected with the towing connection sleeve 6 . The socket is arranged at the end of the towing guide frame 5 .

[0025] The towing group 13 is responsible for connecting with the front-end traction mechanism in the towing seat system. The towing guide frame 5 is a bridge connecting the towing guide frame and the front-end traction mechanism, and can bear the weight of the towing guide frame and the dynamic load generated during towing. The towing guide frame 5 has sufficient strength and toughness. The towing connection sleeve 6 is located on the inner side of the towing guide frame 5 and is connected to the towing guide frame 5 through a transition structure. The towing connection sleeve 6 is the connection point between the towing guide frame 5 and the front-end traction mechanism, allowing the front-end traction mechanism to rotate and swing within a certain range to adapt to road surface changes and steering movements. The socket is set at the end of the towing guide frame 5 and is the interface for direct connection of the front-end traction mechanism. The structural design ensures the reliability of the connection to prevent loosening or breakage during the towing process.

[0026] Furthermore, the sleeve seat is mainly composed of a guide shaft connecting sleeve 7 and a covering connecting frame 8. The covering connecting frame 8 covers the outer side surface of the towing guide frame 5 and is connected to the guide shaft connecting sleeve 7 through fasteners.

[0027] During use: Manually adjust the adjusting guide frame 9 to an appropriate position according to the height of the towed object. Use the connecting shaft 3 to fix the adjusting guide frame 9 at the selected height to ensure that it will not move due to vibration during towing. Connect the towed object to the guide frame connection support at the lower end of the adjusting guide frame 9 to ensure a firm connection. Select a suitable position and use the fixing bolt 11 to fix the connecting backing plate 10 at the position of the intermediate connecting frame 2 and at a position consistent with the towing equipment. At this time, use an external connecting piece to connect the towing equipment and the connecting ear plate 12 in series. Connect the front traction mechanism to the guide shaft connecting sleeve 7 of the socket seat and also connect the traction connecting sleeve 6 to ensure a firm connection. Slowly start the towing vehicle and observe whether there is any abnormal shaking or abnormal noise in the towed object. If any problems are found, stop the vehicle immediately for inspection to ensure that all components are operating in a safe state. During towing, regularly check the connection points, especially after long-term towing or passing through complex terrains. Pay attention to observing the working state of the traction connecting sleeve 6 to ensure that it rotates and swings freely without jamming, thereby completing the towing process.

[0028] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application.
