[0034] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention will be further described, but the invention is not limited to these embodiments.

[0035] As Figures 1-5 shown, an all-round adjustment mechanism for a forklift steering wheel includes a rotating assembly 1 and a lifting assembly 2. The rotating assembly 1 is used to drive the steering wheel 4 to perform a revolution, and the lifting assembly 2 is used to drive the steering wheel 4 to perform a lifting action. The steering wheel 4 is rotatably connected to the lifting assembly 2, so it can rotate, thereby realizing the all-round adjustment of the steering wheel 4, meeting the requirements of the driver's height and habits, etc., and improving driving comfort.

[0036] Specifically, a fixing plate 5 connected to the forklift main body is provided on the forklift. The adjusting mechanism of this embodiment is arranged on the fixing plate 5, that is, the installation of the adjusting mechanism is realized through the fixing plate 5.

[0037] Furthermore, the rotating assembly 1 includes a turntable 11 rotatably arranged on the fixing plate 5 and a first locking member 12 for locking the turntable 11. The lifting assembly 2 includes a sliding seat 21 fixed to the bottom of the turntable 11, a rotating seat 22 slidably disposed through the sliding seat 21, and a second locking member 23 for locking the rotating seat 22. The steering wheel 4 is rotatably connected to the rotating seat 22 through a rotating shaft 3 and is located above the fixing plate 5. That is, the rotation of the turntable 11 drives the sliding seat 21 and the rotating seat 22 to rotate together, and then drives the steering wheel 4 connected to the rotating seat 22 to rotate together, performing a revolution around the center of the turntable 11, and the orientation of the turntable 11 can be adjusted, which is more suitable for the operating habits of the driver, such as left - hand or right - hand operating habits. When the lifting of the steering wheel 4 is required, the sliding of the rotating seat 22 in the sliding seat 21 drives the steering wheel 4 to perform vertical lifting movement together to meet the height condition of the driver. At the same time, the steering wheel 4 is rotatably connected to the rotating seat 22 through the rotating shaft 3, and the self - rotation of the steering wheel 4 can be realized. In this embodiment, a hand - holding part for operating the steering wheel 4 is provided on the steering wheel 4, and the self - rotation of the steering wheel 4 can adjust the position of the hand - holding part, further improving the comfort of the driver, and realizing the omnidirectional adjustment of the forklift steering wheel 4.

[0038] In this embodiment, the self - rotation of the steering wheel 4, that is, the rotation of the rotating shaft 3, is realized by a motor.

[0039] Specifically, the second locking member 23 includes a gear position plate 231 fixed below the turntable 11, a gear position bolt 233 fixed on the turntable 22, a movable block 232 disposed on the gear position plate 231, and a driving head 234 connected to the top of the block 232. A plurality of adjacent gear position grooves 231a are provided on the gear position plate 231. The plurality of gear position grooves 231a are arranged vertically on the gear position plate 231. The gear position bolt 233 is located in one of the gear position grooves 231a. Then, when the gear position bolt 233 is located in different gear position grooves 231a, it means that the turntable 22 is at different heights. Through the setting of the gear position grooves 231a, the height of the turntable 22 can be accurately controlled, improving the lifting precision. The block 232 has a first position for locking the gear position bolt 233 and a second position for unlocking the gear position bolt 233. In this embodiment, a limiting groove is provided on the gear position plate 231, and a plurality of gear position grooves 231a are all arranged on one side of the limiting groove. Under normal circumstances, the gear position bolt 233 can move from the gear position groove 231a into the limiting groove and then switch gears. However, when the gear position blocks the limiting groove, the gear position bolt 233 cannot move out of the gear position groove 231a, thereby locking the turntable 22. A through hole is provided on the fixing plate 5, and the driving head 234 is disposed above the fixing plate 5 through the through hole. The initial position of the block 232 is the first position. When the driver needs to adjust the height of the steering wheel 4, the driver can press the driving head 234, and the driving head 234 can drive the block 232 to move toward the side away from the gear position bolt 233 and move from the first position to the second position to unlock the gear position bolt 233.

[0040] Further, the second locking member 23 further includes a return spring 235. The stopper 232 is provided with an inclined first guiding groove 232a and a second guiding groove 232b. The first guiding groove 232a is arranged at the upper part of the stopper 232, and the second guiding groove 232b is arranged at the lower part of the stopper 232. The first guiding groove 232a gradually moves away from the gear position groove 231a from top to bottom. The second guiding groove 232b has the same inclined direction as the first guiding groove 232a. The gear position plate 231 is provided with a first guiding bolt 231b and a second guiding bolt 231c. The first guiding bolt 231b is inserted into the first guiding groove 232a, and the second guiding bolt 231c is inserted into the second guiding groove 232b. The cooperation between the first guiding bolt 231b and the first guiding groove 232a and the cooperation between the second guiding bolt 231c and the second guiding groove 232b are used to guide the movement of the stopper 232. Since both the first guiding groove 232a and the second guiding groove 232b are inclined and both gradually move away from the gear position groove 231a from top to bottom, when the stopper 232 is in the first position, the first guiding bolt 231b should be located at the bottom of the first guiding groove 232a. Since the first guiding bolt 231b is fixed during this movement process, when the first guiding bolt 231b is at the bottom of the first guiding groove 232a, the stopper 232 is closest to the gear position bolt 233. When the driving head 234 is pressed, the stopper 232 moves downward. Due to the limitation of the first guiding bolt 231b and the second guiding bolt 231c, the stopper 232 can only move obliquely downward, and at this time, it will gradually move away from the gear position bolt 233, thereby realizing unlocking. Among them, one end of the return spring 235 is connected to the first guiding bolt 231b, and the other end of the return spring 235 is connected to the bottom of the stopper 232. When the stopper 232 is in the second position, the return spring 235 is in a stretched state. After pressing down, if the driver releases the driving head 234, the return spring 235 can drive the stopper 232 to reset.

[0041] Further, one end of the swivel base 22 is located below the turntable 11, and the other end of the swivel base 22 passes through the sliding seat 21 and is located above the turntable 11. The sliding seat 21 is located on the outer side of the turntable 11 away from the center of the turntable 11, that is, both the sliding seat 21 and the swivel base 22 are arranged on the outer side of the turntable 11 away from the center of the turntable 11, which can increase the revolution range of the sliding seat 21 and the swivel base 22, and further increase the adjustment range of the steering wheel 4.

[0042] Further, the lifting assembly 2 further includes a lifting spring 24. The two lifting springs 24 are symmetrically distributed outside the rotating base 22. One end of the lifting spring 24 is connected to the bottom of the turntable 11, and the other end of the lifting spring 24 is connected to the bottom end of the rotating base 22. And the lifting spring 24 is in a stretched state. After the stopper 232 moves to the second position, at this time, the gear position bolt 233 is already in an unlocked state. The rotating base 22 can be driven to rise by the lifting spring 24. Using the lifting spring 24 to provide power can save costs. At the same time, after unlocking, the steering wheel 4 can be lowered by pressing, and the operation is relatively simple.

[0043] Further, a first flange plate 51 and a second flange plate 52 are provided below the fixing plate 5. The first flange plate 51 is located in the middle of the fixing plate 5, and the second flange plate 52 is located at the bottom of the first flange plate 51. The fixing plate 5, the first flange plate 51 and the second flange plate 52 enclose a third guiding groove. A plurality of guiding wheels 111 are provided below the turntable 11. One side of the guiding wheel 111 extends into the third guiding groove, and the end face of the guiding wheel 111 is in contact with the end face of the first flange plate 51. The cooperation between the guiding wheel 111 and the third guiding groove is used to ensure the stability of the rotation of the turntable 11 and prevent it from shaking.

[0044] Further, the first locking member 12 for locking the turntable 11 includes a locking bracket 121 and a locking handle 122. The locking bracket 121 is provided on the turntable 11, and one end of the locking bracket 121 passes through the turntable 11 and is provided below the turntable 11. A locking block 121a connected by thread is provided at the end of the locking bracket 121 located below the turntable 11. A locking cap 122a is provided at one end of the locking handle 122. The locking cap 122a is buckled on the locking bracket 121 and can drive the locking bracket 121 to rotate to lock the turntable 11. In this embodiment, the locking block 121a can only rotate with the turntable 11. When the locking bracket 121 rotates, due to the threaded connection relationship between the locking bracket 121 and the locking block 121a, the locking block 121a can rise or fall according to the rotation direction of the locking bracket 121. When the locking block 121a rises, the locking block 121a can abut against the bottom of the fixing plate 5, thereby locking the turntable 11.

[0045] Specifically, a plurality of first gear teeth 121b are provided on the locking bracket 121 at intervals, a plurality of second gear teeth 122c are provided inside the locking cap 122a at intervals, and a locking spring 122b is provided inside the locking cap 122a. When the locking cap 122a is buckled on the locking bracket 121, the locking spring 122b can drive the first gear teeth 121b to engage with the second gear teeth 122c. The rotation of the locking handle 122 can drive the locking bracket 121 to rotate and drive the locking block 121a to fit with the fixing plate 5. In this embodiment, a bolt for compression is provided on the locking bracket 121. During the buckling process of the locking cap 122a, the bolt will compress the locking spring 122b, causing the locking spring 122b to remain in a compressed state. At this time, the locking spring 122b provides a downward acting force on the locking cap 122a, driving the locking cap 122a to move downward. As long as the gaps between the first gear teeth 121b and the second gear teeth 122c are opposite to each other, automatic buckling can be achieved, which is convenient for driving the locking bracket 121 to rotate through the handle.

[0046] Furthermore, a limit nut 121c is provided at the bottom end of the locking bracket 121. The limit nut 121c fits on the bottom end face of the second flange. A first limit block 521 and a second limit block are provided on the bottom end face of the second flange. The limit nut 121c is located between the first limit block 521 and the second limit block. When the turntable 11 rotates, the limit nut 121c can abut against the first limit block 521 or the second limit block. The rotation angle range of the steering wheel 4 can be limited by the first limit block 521 and the second limit block. At the same time, in order to prevent the limit nut 121c from being damaged due to impact with the first limit block 521 and the second limit block, both the first limit block 521 and the second limit block are made of rubber.
