[0061] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0062] In order to achieve an adjustable design for the forklift steering wheel, it may be necessary to introduce some movable parts or connectors on the steering wheel structure, such as setting a linear track. These parts may be slightly fragile compared to the fixed structure. Therefore, it is necessary to ensure the stability and durability of the adjustment structure to ensure that there will be no safety hazards in daily use.

[0063] In some modern forklifts, the steering wheel usually needs to be connected to the electrical system through wires to transmit the control signals on the steering wheel to the forklift's control system to control the direction of the forklift. In addition to the need to connect wires, the steering wheel may need to connect encoders, sensors, etc. to achieve some advanced functions. The setting of movable parts or connectors may conflict with electrical components.

[0064] Reference Figure 1-Figure 5The utility model provides an adjustable forklift steering wheel, comprising a fixed seat 10, a sleeve 20, a locking member 30, and a steering wheel 40. The sleeve 20 is slidably mounted on the fixed seat 10 along a first direction D1, and the sleeve 20 is provided with a guide groove 22 and a slide groove. The guide groove 22 and the slide groove both extend along the first direction D1. The guide groove 22 is slidably connected to the guide member 11. The locking member 30 passes through the first slide groove 21 and is rotatably connected to the fixed seat 10 by a thread, so that the locking member 30 can make the sleeve 20 and the fixed seat 10 abut or separate. The steering wheel 40 is connected to the sleeve 20, and the steering wheel 40 can move with the movement of the sleeve 20. In this solution, the guide member 11 and the guide groove 22 are provided, which can ensure that the sleeve 20 slides along a predetermined track on the fixed seat 10, avoid shaking of the steering wheel 40 during adjustment, and improve the stability and smoothness of the adjustment. A locking member 30 is provided with the first slide groove 21, the locking member 30 is slidably connected with the first slide groove 21, and the locking member 30 extends from the first slide groove 21 into the inner side of the sleeve 20, which can ensure that the connection between the sleeve 20 and the fixing seat 10 is stable and reliable, so that the strength and stability of the overall structure of the steering wheel can be further improved, and it can withstand a large operating force in daily use, and it is not easy to loosen or deform. In the utility model, the sleeve 20 and the fixing seat 10 are sleeved and arranged. This connection method can provide strong support and stability, so that the relative position between the two components is more solid, thereby ensuring that the steering wheel will not loosen or deform during operation, thereby improving the reliability and durability of the overall structure. Therefore, the sleeve 20 and the fixing seat 10 can be set in a sheet metal structure. On the one hand, the weight of the entire structure is reduced, and the matching requirements are also reduced, and the processing difficulty is greatly reduced; on the other hand, since a steering encoder is also installed under the steering wheel, a wiring harness needs to be arranged. The new structure is conducive to the layout of the steering wheel harness and improves the practicality of the structural device.

[0065] Optionally, a plurality of guide members 11 are provided in the guide groove 22, and the plurality of guide members 11 are arranged at intervals along the first direction D1. By providing a plurality of guide members 11 in one guide groove 22, the sleeve 20 can be prevented from swinging relative to the fixing seat 10. Optionally, the plurality of guide grooves 22 are located on different sides of the fixing seat 10. By providing a plurality of guide grooves 22, the displacement of the sleeve 20 relative to the fixing seat 10 in a direction perpendicular to the first direction D1 can be avoided. By providing the guide members 11 and the guide grooves 22, the stability of the connection between the sleeve 20 and the fixing seat 10 is improved, and the stability of the sleeve 20 when moving relative to the fixing seat 10 is ensured.

[0066] Optionally, the fixing seat 10 is constructed as a hollow cylinder. The fixing seat 10 can accommodate electrical components, such as an encoder. By sleeve-fitting the sleeve 20 to the outer periphery of the fixing seat 10, a close connection between the two can be achieved, and the space utilization rate inside the forklift can be improved.

[0067] like Figure 4 As shown, the locking member 30 extends from the first slide groove 21 into the inner side of the sleeve 20. Optionally, the locking member 30 extends into the interior of the fixed seat 10. The fixed seat 10 has a first side wall 101 and a second side wall 102 arranged opposite to each other, and the locking member 30 is rotatably connected to the first side wall 101 and the second side wall 102 respectively. When the locking member 30 rotates, it has at least two rotation points with the fixed seat 10 and at least one rotation point with the sleeve 20. Therefore, the rotational force or the axial extrusion force can be evenly distributed on these contact points.

[0068] Optionally, the fixed seat 10 is also provided with a gasket 31, the gasket 31 is located between the fixed seat 10 and the sleeve 20, and the locking member 30 is rotatably connected to the gasket 31. When the sleeve 20 and the fixed seat 10 are abutted against each other by rotating the locking member 30, at least parts of the sleeve 20 and the fixed seat 10 are close to each other, and the sleeve 20 and the fixed seat 10 squeeze the gasket 31. Through the coordinated arrangement of the locking member 30 and the gasket 31, the sleeve 20 and the fixed seat 10 can be selectively enabled to move relative to each other, and the friction and stability between the sleeve 20 and the fixed seat 10 can also be effectively increased to ensure that the connection between the sleeve 20 and the fixed seat 10 is more firm and reliable. In addition, the gasket 31 has a certain elasticity. Through the buffering effect of the gasket 31, the fixing degree between the sleeve 20 and the fixed seat 10 can be adjusted within a certain range, which can meet the usage habits of different people.

[0069] Optionally, the locking member 30 is provided with a boss 32, which is located on the side of the first slide groove 21 away from the fixed seat 10, and the width of the boss 32 is greater than the width of the first slide groove 21. When locking is required, when the locking member 30 is rotated, the boss 32 contacts the sleeve 20, and the locking member 30 is further rotated, and the boss 32 applies a force to the sleeve 20 to approach the fixed seat 10, and the sleeve 20 and the fixed seat 10 are squeezed, thereby achieving locking. When loosening is required, the locking member 30 is rotated in the opposite direction, the boss 32 is separated from the sleeve 20, and the squeezing force between the sleeve 20 and the fixed seat 10 is removed, thereby achieving separation.

[0070] Optionally, a gas spring 50 is further included, one end of which is connected to the fixing seat 10, and the other end is connected to the sleeve 20. The upper mounting plate 33 is welded to the sleeve 20, and the lower mounting plate 34 is welded to the fixing seat 10. The gas spring 50 is installed on the upper mounting plate 33 and the lower mounting plate 34 through the pin 35. When adjusting the steering wheel upward in the longitudinal direction, the gas spring 50 releases the pressure to give the entire steering wheel an upward force, and when it reaches the appropriate position, the locking member 30 is locked; when adjusting the steering wheel downward in the longitudinal direction, the gas spring 50 is compressed downward under the gravity of the entire steering wheel and a small external force applied by the forklift driver, and when it reaches the appropriate position, the locking member 30 is locked.

[0071] like Figure 5-Figure 6 As shown, the steering wheel 40 is provided with a second slide groove 41 extending along the second direction D2. The utility model also includes a slide rail 60 and an adjusting knob 70. The slide rail 60 is connected to the sleeve 20 and can move with the movement of the sleeve 20. The slide rail 60 extends along the second direction D2, and the steering wheel 40 is slidably mounted on the slide rail 60 along the second direction D2. The adjusting knob 70 passes through the second slide groove 41 and is screwed into the steering wheel 40. The adjusting knob 70 is connected to the slide rail 60 by a thread, and a friction portion 71 is provided on the adjusting knob 70, and the friction portion 71 can conflict with the steering wheel 40. The friction portion 71 can conflict with the steering wheel 40, so the relative position of the steering wheel 40 and the slide rail 60 can be conveniently adjusted by the knob, and the flexibility and convenience of operation are high. Through the design of the threaded connection and the friction portion 71, the connection firmness between the adjusting knob 70 and the slide rail 60 can be improved, thereby enhancing the durability of the entire structure and reducing the looseness or wear caused by long-term use.

[0072] Optionally, the sleeve 20 is provided with an upper mounting plate 33. The fixing seat 10 is provided with a lower mounting plate 34. The two ends of the gas spring 50 are connected to the upper mounting plate 33 and the lower mounting plate 34 respectively. The upper mounting plate 33 and the lower mounting plate 34 are arranged at intervals along the first direction D1. The gas spring 50 is installed on the upper mounting plate 33 and the lower mounting plate 34 through the pin 35. When adjusting the gas spring 50 upward in the longitudinal direction D1, the gas spring 50 releases pressure to give the entire steering wheel (including the sleeve 20, the slide rail 60 and the steering wheel 40) an upward force, and when it reaches a suitable position, the locking member 30 is locked; when adjusting the gas spring 50 downward in the longitudinal direction D1, the gas spring 50 is compressed downward under the gravity of the entire steering wheel (including the sleeve 20, the slide rail 60 and the steering wheel 40) and a small part of the external force applied by the forklift driver, and when it reaches a suitable position, the locking member 30 is locked. The gas spring 50 can provide appropriate support force during the adjustment process, so that the steering wheel maintains stability during height adjustment, helps to avoid shaking or instability during operation, and improves the operator's operating efficiency and accuracy.

[0073] The utility model also provides a forklift, the steering wheel of the forklift can be adjusted, and the steering wheel will not be loose or deformed during adjustment and operation, thereby improving the reliability and durability of the overall structure.
