Description

Technical Field

[0001] This invention relates to the technical field of steering wheel adjustment, and specifically to a forklift steering wheel adjustment mechanism. Background Technology

[0002] Currently, most forklift steering wheels can only be adjusted in one direction, and their adjustment range is small, which cannot meet the needs of different drivers. Therefore, some multi-directional adjustable steering wheels have gradually emerged. However, each direction of adjustment is controlled by a separate handle, so multiple adjustment handles need to be arranged, making the adjustment more troublesome.

[0003] In existing technologies, there are also multi-position handles for different adjustment directions. However, these all require locking the adjustment in one direction before adjusting the position in another direction. In other words, the steering wheel cannot be adjusted to the correct position in one go and needs to be adjusted in batches, resulting in low adjustment efficiency. Summary of the Invention

[0004] This invention addresses the aforementioned problems and aims to provide a forklift steering wheel adjustment mechanism that enables the steering wheel to be adjusted in multiple directions at once, resulting in high adjustment efficiency.

[0005] To achieve the above objectives, the present invention provides a forklift steering wheel adjustment mechanism, comprising:

[0006] Positioning components, which are fixed to the forklift body;

[0007] A rotating component is located on one side of the positioning component. One end of the rotating component is hinged to the forklift body and can rotate along the height direction of the forklift body.

[0008] A translator is movably mounted on one side of the rotating component. The translator can translate along the length of the rotating component and rotate with the rotating component. The steering wheel is fixed to the translator.

[0009] A locking member has one end that passes through the positioning member, the rotating member, and the translating member in sequence and abuts against the outer side of the translating member. The locking member can drive the translating member to abut against the rotating member to lock the translating member. When the locking member drives the translating member to abut against the rotating member, the other end of the locking member can abut against the outer side of the positioning member to lock the rotating member.

[0010] According to the forklift steering wheel adjustment mechanism described above, the rotating component is a rotating plate, the translating component is a translating plate, one end of the rotating plate is rotatably connected to the forklift body through a first rotating shaft, and the rotating plate is provided with a plurality of first guide wheels arranged along the length direction on the side near the translating plate, and the translating plate is provided with a first guide groove arranged along the length direction of the rotating plate, and the plurality of first guide wheels can be inserted into the first guide groove.

[0011] According to the forklift steering wheel adjustment mechanism described above, the translation plate is generally L-shaped, the translation plate includes a first connecting part and a second connecting part, the first connecting part is arranged along the length direction of the rotating plate on one side of the rotating plate, the first guide groove is located on the first connecting part, the bottom end of the second connecting part is connected to one end of the first connecting part, and the steering wheel is installed on the top end of the second connecting part.

[0012] According to the forklift steering wheel adjustment mechanism described above, a first protrusion is provided on the side of the rotating plate near the translation plate, and multiple second rotating shafts are provided on the outer side of the first protrusion, with multiple first guide wheels corresponding one-to-one with multiple second rotating shafts.

[0013] According to the forklift steering wheel adjustment mechanism described above, the locking member includes an adjustment handle and a locking shaft. The locking shaft has a first end and a second end. The first end of the locking shaft is located outside the positioning member. The second end of the locking shaft passes through the positioning member, the rotating plate, and the translation plate in sequence and is located outside the translation plate. The adjustment handle is fixed on the first end of the locking shaft. A locking plate is sleeved on the second end of the locking shaft. When the locking shaft rotates, it can drive the locking plate to move away from or closer to the translation plate to lock or unlock the translation plate.

[0014] According to the forklift steering wheel adjustment mechanism described above, the second end of the locking shaft is a threaded end, a nut is provided on the locking plate, the second end of the locking shaft passes through the locking plate and is threadedly engaged with the nut, and a washer is provided at the end of the second end of the locking shaft, the washer can abut against the outside of the nut to restrict the locking shaft from disengaging from the locking plate.

[0015] According to the forklift steering wheel adjustment mechanism described above, one end of the second rotating shaft protrudes out of the outer side of the first guide wheel, and the two ends of the locking plate are provided with limiting grooves. The locking plate is locked between the two second rotating shafts, and the ends of the second rotating shafts can extend into the limiting grooves.

[0016] According to the forklift steering wheel adjustment mechanism described above, the positioning element is a positioning plate, the positioning plate is provided with an arc-shaped groove, and the locking shaft passes through the arc-shaped groove. When the rotating plate rotates around the first rotating shaft, the locking shaft moves along the arrangement direction of the arc-shaped groove.

[0017] According to the forklift steering wheel adjustment mechanism described above, when the adjustment handle drives the locking shaft to rotate in the first direction, the locking plate can drive the translation plate to abut against the outer side of the first protrusion to lock the translation plate, and the end of the adjustment handle can abut against the outer side of the positioning plate to lock the rotating plate.

[0018] When the adjusting handle drives the locking shaft to rotate in the second direction, the locking plate can move away from the translation plate to unlock the translation plate, and the end of the adjusting handle can disengage from the positioning plate to unlock the rotating plate.

[0019] The forklift steering wheel adjustment mechanism described above further includes a positioning cylinder, which is fixed to the rotating plate, and the piston rod of the positioning cylinder is rotatably connected to one end of the positioning plate. The positioning cylinder and the rotating plate form a crank-connecting rod mechanism to support the rotating plate at a preset height.

[0020] The present invention has the following beneficial effects:

[0021] 1. The locking mechanism can simultaneously lock and unlock the rotating and translating parts. In the unlocked state, the steering wheel can be directly driven to adjust the height and horizontal forward and backward directions. After the adjustment is completed, the locking mechanism can be used to lock the parts. The adjustment is convenient and efficient.

[0022] 2. The locking mechanism uses an adjusting handle and a locking shaft, so locking and unlocking only require turning the adjusting handle, making operation convenient.

[0023] 3. Multiple first guide wheels are provided on one side of the rotating plate, and first guide grooves corresponding to the first guide wheels are provided on the translation plate. This can guide the horizontal movement of the translation plate, make the movement of the translation plate easier, and ensure that the translation plate can be driven to rotate when the rotating plate rotates.

[0024] 4. A positioning cylinder is provided. The positioning cylinder and the rotating plate form a crank-connecting rod mechanism, which can provide force to keep the rotating plate at a preset height during rotation and prevent the rotating plate from falling automatically.

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the invention is not limited to these embodiments.

[0038] like Figure 1-4 As shown, a forklift steering wheel adjustment mechanism includes a positioning component, a rotating component, and a translating component. The positioning component is fixed to the forklift body, the rotating component is located on one side of the positioning component, and one end of the rotating component is hinged to the forklift body and can rotate along the height direction of the forklift body. The translating component is movably installed on one side of the rotating component and can move along the length direction of the rotating component. In this embodiment, the rotating component is arranged along the front-rear direction of the forklift body, that is, the translating component can move along the front-rear direction of the forklift body and can rotate with the rotating component. The steering wheel 5 is fixed on the translating component. When the rotating component rotates, the height of the steering wheel 5 can be adjusted. When the translating component moves back and forth, it can drive the steering wheel 5 to move back and forth, realizing multi-directional adjustment of the steering wheel 5. The locking component 4 can lock or unlock the rotating component and the translating component simultaneously, making its operation simpler and facilitating the adjustment of the steering wheel 5.

[0039] In this embodiment, a cover 7 is also included, and the positioning component, rotating component and translation component are all located inside the cover 7.

[0040] Specifically, one end of the locking member 4 passes through the positioning member, the rotating member, and the translation member in sequence and abuts against the outer side of the translation member. The locking member 4 can drive the translation member to abut against the rotating member. At this time, the translation member cannot continue to move back and forth, so as to lock the translation member. When the locking member 4 drives the translation member to abut against the rotating member, the other end of the locking member 4 can abut against the outer side of the positioning member. At this time, the locking member 4 cannot move, which in turn prevents the rotating member from rotating, so as to lock the rotating member.

[0041] In this embodiment, the rotating component is a rotating plate 2, the translating component is a translating plate 3, and the positioning component is a positioning plate 1. One end of the rotating plate 2 is rotatably connected to the forklift body via a first rotating shaft 21. The rotating plate 2 is provided with a plurality of first guide wheels 22 arranged along the length direction on the side near the translating plate 3. The translating plate 3 is provided with a first guide groove 31 arranged along the length direction of the rotating plate 2. The plurality of first guide wheels 22 can all extend into the first guide groove 31. When the rotating plate 2 rotates around the first rotating shaft 21, the translating plate 3 can be driven to rotate by the plurality of first guide wheels 22, thereby driving the steering wheel 5 located on the translating plate 3 to move in the height direction. At the same time, the plurality of first guide wheels 22 can also provide guidance for the translational movement of the translating plate 3.

[0042] The translation plate 3 is L-shaped and includes a first connecting part 32 and a second connecting part 33. The first connecting part 32 is arranged on one side of the rotating plate 2 along the length direction of the rotating plate 2. The first guide groove 31 is located on the first connecting part 32. The bottom end of the second connecting part 33 is connected to one end of the first connecting part. The steering wheel 5 is installed on the top end of the second connecting part 33. When the first connecting part 32 rotates with the rotating plate 2, it can drive the top end of the second connecting part 33 to move up and down, thereby driving the steering wheel 5 to move up and down and adjusting the height of the steering wheel 5.

[0043] Furthermore, a first protrusion 23 is provided on the side of the rotating plate 2 near the translation plate 3. Multiple second rotating shafts 231 are provided on the outer side of the first protrusion 23. Multiple first guide wheels 22 correspond one-to-one with the multiple second rotating shafts 231. When the translation plate 3 is driven by the locking member 4 to move towards the side near the rotating plate 2, the inner side of the translation plate 3 will abut against the outer side of the first protrusion 23 to increase the friction between the translation plate 3 and the first protrusion 23, thereby locking the translation plate 3.

[0044] Specifically, the locking component 4 includes an adjusting handle 41 and a locking shaft 42. The locking shaft 42 has a first end and a second end. The first end of the locking shaft 42 is located outside the positioning component, and the second end of the locking shaft 42 passes through the positioning component, the rotating plate 2, and the translation plate 3 in sequence, and is located outside the translation plate 3. The locking shaft 42 is rotatably connected to the rotating plate 2. When the locking shaft 42 is locked, the rotating plate 2 can be locked, preventing the rotating plate 2 from rotating. The adjusting handle 41 is fixed to the first end of the locking shaft 42, and a locking mechanism is sleeved on the second end of the locking shaft 42. The second end of the locking shaft 42 is threadedly connected to the locking plate 421. When the locking shaft 42 rotates, it can drive the locking plate 421 to move away from or towards the translation plate 3. When the locking plate 421 is driven to move towards the translation plate 3, the locking plate 421 can drive the translation plate 3 to move towards the first protrusion 23, thereby achieving the contact between the translation plate 3 and the first protrusion 23 and locking the translation plate 3. When the locking plate 421 is driven to move away from the translation plate 3, the locking plate 421 can release the locking of the translation plate 3.

[0045] To achieve threaded connection between the locking shaft 42 and the locking plate 421, the second end of the locking shaft 42 is designated as a threaded end. A nut 421a is provided on the locking plate 421. The second end of the locking shaft 42 passes through the locking plate 421 and engages with the nut 421a through the thread. Since the nut 421a is fixed on the locking plate 421, when the locking shaft 42 rotates, it can drive the nut 421a to move along the axial direction of the locking shaft 42, and at the same time drive the locking plate 421 to move along the axial direction of the locking shaft 42. Furthermore, a washer 421b is provided at the end of the second end of the locking shaft 42. The washer 421b can abut against the outer side of the nut 421a to prevent the locking shaft 42 from disengaging from the locking plate 421.

[0046] To prevent the locking shaft 42 from driving the locking plate 421 to rotate, one end of the second rotating shaft 231 is positioned to protrude outward from the outside of the first guide wheel 22. The locking plate 421 has limiting grooves 421c at both ends. The locking plate 421 is engaged between the two second rotating shafts 231, and the ends of the second rotating shafts 231 can extend into the limiting grooves 421c. That is, the locking plate 421 can be positioned by the cooperation between the second rotating shafts 231 and the limiting grooves 421c, so that it can only move along the axial direction of the second rotating shafts 231.

[0047] In order to guide and limit the rotation of the rotating plate 2, an arc-shaped groove 11 is provided on the positioning plate 1. The locking shaft 42 passes through the arc-shaped groove 11. When the rotating plate 2 rotates around the first rotating shaft 21, the locking shaft 42 moves along the arrangement direction of the arc-shaped groove 11. The arc-shaped groove 11 is a through groove to limit the maximum rotation angle of the rotating plate 2.

[0048] In this embodiment, when the adjusting handle 41 drives the locking shaft 42 to rotate in the first direction, the locking plate 421 can drive the translation plate 3 to abut against the outer side of the first protrusion 23 to lock the translation plate 3, and the end of the adjusting handle 41 can abut against the outer side of the positioning plate 1 to lock the rotating plate 2. When the adjusting handle 41 drives the locking shaft 42 to rotate in the second direction, the locking plate 421 can move away from the translation plate 3 to unlock the translation plate 3, and the end of the adjusting handle 41 can disengage from the positioning plate 1 to unlock the rotating plate 2. The first direction is the forward rotation direction and the second direction is the reverse rotation direction.

[0049] To ensure that the steering wheel 5 does not fall off automatically during rotation, a positioning cylinder 6 is provided. The positioning cylinder 6 is fixed on the rotating plate 2, and the piston rod of the positioning cylinder 6 is rotatably connected to one end of the positioning plate 1. The positioning cylinder 6 and the rotating plate 2 form a crank-connecting rod mechanism. After rotating at a preset angle, the positioning cylinder 6 rotates together, but it provides an inclined force acting on the rotating plate 2, which can drive the locking shaft 42 to fit against the side wall of the arc groove 11 and support the rotating plate 2 to remain at a preset height.
