Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and is particularly applicable to a device for adjusting the length of forklift fork teeth. Background Technology

[0002] Currently, shelves are often grouped together, which results in very small gaps between adjacent shelves. Since the original fork tines of forklifts are relatively long, if the forklift tines insert too much, they may tip over the opposite pallet. If they insert too little, the pallet being transferred may fall. To ensure reliable pallet support, the current method used is as follows: 1. Visual inspection from the side is required each time the forklift is removed, but this method is inefficient; 2. Draw yellow lines on the fork tines, but this method is inconvenient to observe, not very accurate, and there is still a risk of goods falling off. 3. Having others observe and direct from the sidelines is helpful, but this method wastes manpower; Therefore, there is an urgent need for a device that can adjust the length of the fork teeth.

[0018] It should be understood that the accompanying drawings are for illustrative purposes only.

[0019] A device for adjusting the length of forklift fork teeth, such as Figures 1-7 As shown, it includes a connecting shaft 33 disposed on the fork teeth and a limiting member 2 that can rotate around the connecting shaft 33.

[0020] The fork includes a mounting plate 12 connected to the forklift and a support plate 11 for carrying goods. The mounting plate 12 is connected to the support plate 11 and the mounting plate 12 is set at an angle to the support plate 11. Furthermore, the mounting plate 12 is set perpendicular to the support plate 11 to form a support space. The mounting plate 12 and the support plate 11 are integrally formed.

[0021] The connecting shaft 33 can be set on the mounting plate 12 or on the bearing plate 11. In this solution, the connecting shaft 33 is set on the mounting plate 12. Furthermore, the connecting shaft 33 can be glued or welded to the mounting plate 12, or it can be set directly through the mounting plate 12. It is only necessary to fix the connecting shaft 33 on the mounting plate 12 so that the limiting member 2 can be stably connected. In this solution, a fixing member 3 is provided on the mounting plate 12. The fixing member 3 includes a fixing plate 31 and extension plates 32 set on both sides of the fixing plate 31. The two extension plates 32 are parallel and extend towards the same side. The fixing plate 31 is set parallel to the mounting plate 12. The fixing plate 31 can be set tightly against the mounting plate 12 or a gap can be left. One end of the extension plate 32 is connected to the fixed plate 31, and the other end of the extension plate 32 extends toward the side away from the support plate 11 and protrudes from the mounting plate 12. The mounting plate 12 is accommodated between the two extension plates 32, so that the extension plate 32 does not affect the width of the support space and does not affect the placement of the pallet.

[0022] The connecting shaft 33 passes through the two extension plates 32 and is connected to the limiting member at both ends. The fixing member and the connecting shaft enclose a fixed space. The mounting plate is accommodated in the fixed space. The fixing member 3 is set to avoid damage to the fork teeth and is easy to remove when the length of the fork teeth does not need to be adjusted.

[0023] The limiting member 2 is disposed at the ends of the bearing plate 11 and the mounting plate 12 that are close to each other. The limiting member 2 includes a limiting plate 22 connected to the connecting shaft 33 and a connecting plate 21 connected to the limiting plate 22. Two limiting plates 22 are provided, and the two limiting plates 22 are parallel and extend towards the same side. The distance between the two limiting plates 22 is greater than the width of the mounting plate 12. Both limiting plates 22 are connected to the connecting plate 21. The two limiting plates 22 and the connecting plate 21 form a U-shaped groove. In the retracted state, the mounting plate 12 is accommodated in the U-shaped groove. During rotation, the mounting plate 12 and the bearing plate 11 restrict the movement of the connecting plate 21, so that the connecting plate 21 is always within the bearing space. The connecting plate 21 is used to limit the excessive rotation of the limiting plate 22 to prevent the inability to adjust the length of the fork teeth.

[0024] The limiting member 2 includes a retracted state and a limiting state. In the retracted state, the connecting plate 21 is set close to the mounting plate 12, and the mounting plate 12 is accommodated between the two limiting plates 22. The limiting plates 22 extend towards the side away from the support plate 11. At this time, the bearing space of the fork teeth is the largest, and the limiting member 2 does not affect the placement of the pallet. In the limiting state, the connecting plate 21 is close to the support plate 11, and the limiting plate 22 is set above the support plate 11 and protrudes from the support plate 11. The limiting plate 22 prevents the pallet from moving towards the side closer to the mounting plate 12, so as to adjust the length of the fork teeth.

[0025] To ensure the rotation of the limiting plate 22 and its limiting position after rotation, an adjustment hole 23 and a locking hole 24 are provided on the limiting plate 22. The adjustment hole 23 is located below the locking hole 24 and communicates with the locking hole 24. When the connecting shaft 33 is located in the adjustment hole 23, the limiting member 2 can switch between a retracted state and a limiting state. When the connecting shaft 33 is located in the locking hole 23, the limiting member 2 is in a retracted state.

[0026] Furthermore, the adjusting hole 23 is circular, and the diameter of the adjusting hole 23 is greater than or equal to the diameter of the connecting shaft 33, so that the limiting member 2 can rotate when the connecting shaft 33 is located inside the adjusting hole 23.

[0027] To ensure the locking of the limiting member 2, a locking plane is provided axially on the connecting shaft 33, and a locking side is provided on the locking hole 24 to cooperate with the locking plane 331. The locking side cooperates with the locking plane 331 to restrict the rotation of the limiting member 2. Furthermore, two locking planes 331 are provided, and the two locking planes 331 are arranged in parallel. Based on this, the width of the locking hole 24 is equal to or greater than the straight distance between the two locking planes, but less than the diameter of the connecting shaft 33. The length of the locking hole 24 is greater than or equal to the width of the connecting shaft 33, so that when the connecting shaft 33 is located in the locking hole 24, the limiting member 2 can move linearly, but cannot rotate.

[0028] When the limiting member 2 is adjusted from the retracted state to the limiting state... A force is applied to the limiting plate 22, causing it to move linearly while the connecting shaft 33 remains stationary. Due to the movement of the limiting member 2, the connecting shaft 33 enters the adjusting hole 23 from the locking hole 24. At this time, the limiting member 2 rotates toward the bearing plate 11. After the connecting plate 21 contacts the bearing plate 11, the limiting member 2 adjusts to a limiting state, and the limiting plate 22 extends, restricting the pallet from moving closer to the mounting plate 12. At this time, because the limiting member 2 rotates while the connecting shaft 33 remains stationary, and because the width of the locking hole 24 is smaller than the diameter of the connecting shaft 33, the limiting member 2 cannot move again. The connecting shaft 33 remains within the adjusting hole 23 and will not move due to the pushing force of the pallet. When the limiting member 2 is adjusted from the limiting state to the retracted state... A force is applied to the limiting plate 22, causing it to rotate while the connecting shaft 33 remains stationary. At this time, the limiting member 2 rotates towards the mounting plate 12. After the connecting plate 21 contacts the mounting plate 12, the limiting member 2 adjusts to a retracted state. At this point, the center of the connecting shaft 33 and the center of the locking hole 24 are on the same horizontal plane. A force is applied to the limiting plate 22 again, causing it to move linearly. Due to this movement, the connecting shaft 33 enters the locking hole 24 from the adjusting hole 23. Since the locking hole 24 does not support rotation of the connecting shaft 33 within it, the limiting member remains retracted and does not rotate towards the support plate 11. The limiting plate 22 extends away from the support plate 11, without affecting the pallet's movement towards the mounting plate 12.

[0029] The fixing member 3 is set close to the mounting plate 12. After the limiting member 2 is connected to the connecting shaft 33, it is set on the outside of the fixing member 3 away from the mounting plate 12. In order to prevent the connecting shaft 33 from falling off the limiting member 2 and the fixing member 3, limiting pins are provided at both ends of the connecting shaft 33. In order to prevent the limiting pins from wearing the limiting member, a gasket 4 is provided between the limiting member and the limiting pin.

[0030] At least one limiting member 2 is provided. When two or more limiting members 2 are provided, the limiting members 2 are sequentially arranged on the outside of the fixing member 3. The height of the limiting members 2 increases sequentially from the inside to the outside. According to the length that the fork tooth needs to be adjusted, a suitable limiting member 2 is selected. In order to ensure that the limiting member 2 set on the inside can be rotated out for use, a clearance space 211 is provided on the connecting plate 21. The clearance space 211 can accommodate the connecting plate 21 of other limiting members 2 that is lower than this limiting member 2, so as to facilitate the use of any limiting member 2. In this solution, three limiting members 2 are provided.

[0031] This utility model mainly designs a device for adjusting the length of forklift fork teeth. By setting a rotatable limiting member 2, when the length of the fork teeth needs to be adjusted, the limiting member 2 is moved to be close to the support plate 11. The limiting plate 22 is set above the support plate 11 to prevent the pallet from continuing to move closer to the mounting plate 12, so as to adjust the length of the fork teeth. The appropriate limiting plate 22 is selected according to the required length of the fork teeth. A fixing member 3 is set to avoid damage to the fork teeth by the connecting shaft 33, and it is easy to disassemble and maintain.

However, the present invention is not limited to the specific details of the above embodiments.
