Description

Technical Field

[0001] This utility model relates to the field of steering column technology, and in particular to an adjustment structure for a heavy-duty truck steering column. Background Technology

[0002] To facilitate driver use, most existing heavy-duty truck steering columns are adjustable in height and angle, but their adjustment structures are relatively complex, resulting in high production costs and inconvenience for drivers. Utility Model Content

[0003] To address the problems of complex design, high production costs, and inconvenience for drivers in existing heavy-duty truck steering column adjustment structures, this invention provides a new heavy-duty truck steering column adjustment structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A heavy-duty truck steering column adjustment structure includes a fixed plate and a steering shaft assembly. The bottom end of the steering shaft assembly is connected to the steering gear of the heavy-duty truck, and the top end is provided with a telescopic rod for connecting the steering wheel and adjusting the height of the steering wheel. The fixed plate has ear plates on both sides of its top, and each ear plate has an arc-shaped hole. A connecting plate is rotatably provided in the middle of the fixed plate, and a hoop is provided on the top of the connecting plate for clamping the telescopic rod. A fixed block is provided on one side of the ear plate, and a pull rod passing through the arc-shaped hole is connected between the two fixed blocks. A rotating rod is rotatably connected to one side of the fixed block. One end of the rotating rod is provided with a handle, and the other end passes through the pull rod. An eccentric cam is provided at the contact point between the rotating rod and the pull rod.

[0005] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is simple, the manufacturing and installation costs are reduced, and the height and angle adjustment of the steering wheel are also simple, making it easy for the driver to operate.

[0008] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0010] like Figures 1 to 5 As shown, this utility model embodiment includes a fixed plate 1 and a steering shaft assembly 2. The bottom end of the steering shaft assembly 2 is connected to the steering gear of the heavy truck, and the top end is provided with a telescopic rod 3 for connecting the steering wheel and adjusting the height of the steering wheel. The fixed plate 1 has ear plates 6 on both sides of the top, and each ear plate 6 has an arc-shaped hole 601. A connecting plate 4 is rotatably provided in the middle of the fixed plate 1, and a hoop 5 is provided on the top of the connecting plate 4 for clamping the telescopic rod 3. A fixing block 7 is provided on one side of the ear plate 6, and a pull rod 10 passing through the arc-shaped hole 601 is connected between the two fixing blocks 7. A rotating rod 9 is rotatably connected to one side of the fixing block 7. One end of the rotating rod 9 is provided with a handle 8, and the other end passes through the pull rod 10. An eccentric cam 901 is provided at the contact point between the rotating rod 9 and the pull rod 10.

[0011] like Figure 3 As shown, when it is necessary to adjust the height or angle of the steering wheel, the driver only needs to turn the handle 8, causing the lever 9 to rotate. Since the eccentric cam 901 on the lever 9 is in contact with the pull rod 10, the rotation of the eccentric cam 901 pushes the pull rod 10 to the left, thereby loosening the clamp plate 5 and the ear plate 6, and no longer locking the telescopic rod 3 and the connecting plate 4. At this time, the height of the steering wheel can be adjusted by extending or retracting the telescopic rod 3, or the angle of the steering wheel can be adjusted by rotating the connecting plate 4. After adjustment, turn the handle 8 in the opposite direction to move the pull rod 10 to the right to reset, locking the clamp plate 5 and the ear plate 6.

[0012] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
