[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 and Figure 4 As shown, this embodiment provides a forklift that is easy to adjust the counterweight, including a frame 1 and a plurality of detachable counterweights 11. An adjusting device for moving up and down is provided at one end of the frame 1 away from the forks, connecting plates 7 are symmetrically fixed on both sides of the adjusting device, an insertion rod 9 is vertically fixed to one side of the connecting plate 7, and the counterweight 11 is installed in the insertion rod 9. A lifting cavity 2 is symmetrically opened on the frame 1 below the adjusting device, and the connecting plate 7 slides up and down in the lifting cavity 2 through the adjustment device.

[0029] The improvement of this embodiment lies in that an adjustment device is provided at one end of the frame 1. When the counterweight 11 needs to be taken out, the height of the connecting plate 7 and the insertion rod 9 is adjusted by using the adjustment device, so that the insertion rod 9 is gradually separated from the counterweight 11 from top to bottom, thereby releasing the restriction of the insertion rod 9 on the topmost counterweight 11, avoiding the situation where the counterweight 11 needs to be lifted to be taken out from the insertion rod 9, reducing the physical effort in carrying, and enhancing the stability of the entire vehicle. At the same time, there is no blocking member at the top of the insertion rod 9, which facilitates the subsequent removal of the counterweight 11 from top to bottom.

[0030] like Figure 4 As shown, in order to realize the height adjustment of the connecting plate 7 and the insertion rod 9 by the adjusting device, the adjusting device includes a mounting plate 3, the mounting plate 3 is hollow, and a threaded rod 5 is vertically rotatably connected at the center of the hollow part of the mounting plate 3, and the threaded rod 5 is threadedly connected to a moving block 6, and a rotating part 4 is fixed to the end of the threaded rod 5 close to the mounting plate 3. The connecting plate 7 is welded and fixed into a Z shape by an upper end plate, a middle end plate and a lower end plate in sequence, and one end of the upper end plate of the connecting plate 7 is fixed to one side of the moving block 6, and the insertion rod 9 is fixed to the side of the top surface of the lower end plate away from the middle end plate, and the threaded rod 5 is driven to rotate by the rotating part 4, so that the moving block 6 drives the connecting plate 7 to slide up and down in the hollow part of the mounting plate 3.

[0031] like Figure 3 As shown, in order to improve the stability of the connecting plate 7 when it moves up and down, T-shaped sliding grooves are symmetrically opened on both sides of the mounting plate 3, and T-shaped guide blocks 8 are fixed on both sides of one end of the connecting plate 7 fixed to the moving block 6. The guide block 8 is slidably connected to the sliding groove of the mounting plate 3 to limit the moving direction of the connecting plate 7, thereby improving the stability of the connecting plate 7 when it moves up and down.

[0032] like Figure 2 and Figure 3 As shown, considering that when the bottom plate of the connecting plate 7 is separated from the bottom surface of the bottommost counterweight 11, the counterweight 11 is prevented from moving to the lifting chamber 2 together with the connecting plate 7, a storage rack 10 is installed between the bottom plate of the connecting plate 7 and the counterweight 11, and both the storage rack 10 and the counterweight 11 are provided with through grooves, and the storage rack 10 and the counterweight 11 are sleeved on the insertion rod 9 through the through grooves. The length and width dimensions of the storage rack 10, the counterweight 11, the top surface of the bottom plate of the connecting plate 7 and the lifting chamber 2 are in the relationship that the storage rack 10 is larger than the counterweight 11, the counterweight 11 is larger than the lifting chamber 2, and the lifting chamber 2 is larger than the bottom surface of the bottom plate of the connecting plate 7, so that when the connecting plate 7 is separated from the counterweight 11 through the lifting chamber 2, the counterweight 11 is supported by the storage rack 10 and the frame 1.

[0033] like Figure 4 and Figure 5 As shown, considering that when a forklift uses a counterweight 11 to increase weight, the counterweight 11 is mostly placed directly. If the forklift shakes when moving, the counterweight 11 is prone to collision and damage. Therefore, slots are symmetrically provided at the upper and lower ends of the center of one side of the counterweight 11. A fixing piece 12 is clamped in the slot of the counterweight 11. Two chambers are symmetrically provided in the fixing piece 12. A spring 13 is provided in each chamber. One end of the spring 13 is fixed to the bottom of the chamber of the fixing piece 12. The other end of the spring 13 is fixed to a limit plate 14. The limit plate 14 is slidably connected in the chamber. A pull plate 16 is provided on the side of the limit plate 14 away from the chamber of the fixing piece 12. Slots are provided at the centers of the two inner walls without opposite surfaces in the slot of the counterweight 11. A first clamping block 15 is fixed on the side of the limiting plate 14 away from the spring 13, and a second clamping block 17 is symmetrically provided on the side of the fixing member 12 away from the pulling plate 16. The first clamping block 15 is clamped in the slot on the same side of the two counterweight blocks 11 slots, and the second clamping block 17 is clamped in the slots on the opposite sides of the two counterweight blocks 11 slots. By pressing the pulling plate 16, the first clamping block 15 on one side of the limiting plate 14 is contracted into the chamber of the fixing member 12, and the second clamping block 17 of the fixing member 12 is inserted into the slot on the same side of the two counterweight blocks 11 slots, and the pulling plate 16 is released. Under the elastic force of the spring 13, the second clamping block 17 is inserted into the slots on the opposite sides of the two counterweight blocks 11 slots, thereby fixing the counterweight blocks 11 and preventing the counterweight blocks 11 from being damaged by impact due to bumps.

[0034] In summary, the working principle of this scheme is as follows:

[0035] The storage rack 10 and the counterweights 11 are sequentially placed on the lifting chamber 2 of the vehicle frame 1, and the through slots of the storage rack 10 and the counterweights 11 are placed corresponding to the top of the insertion rod 9. The threaded rod 5 is driven to rotate synchronously by rotating the rotating member 4, so that the moving block 6 drives the connecting plate 7 and the insertion rod 9 to move up and down, and the insertion rod 9 is allowed to pass through the through slots of the storage rack 10 and the counterweights 11 to preliminarily fix the storage rack 10 and the counterweights 11. Then, the fixing member 12 is taken out, and the pull plate 16 is pressed to shrink the first block 15 on one side of the limit plate 14 into the chamber of the fixing member 12, and the second block 17 of the fixing member 12 is inserted into the two slots of the counterweights 11 In the slot on the same side, release the pull plate 16, and under the action of the elastic force of the spring 13, the second block 17 is inserted into the slot on the opposite side of the slots of the two counterweight blocks 11, and the installation and fixing process of the counterweight block 11 can be completed. When the counterweight block 11 needs to be removed, rotate the rotating part 4 to lower the insertion rod 9, and the top of the insertion rod 9 is lower than the bottom surface of the counterweight block 11 to be removed. Press the pull plate 16 to shrink the first block 15 on one side of the limit plate 14 into the chamber of the fixing part 12, and extract the fixing part 12 to disengage the second block 17 from the slot on the same side of the two counterweight blocks 11 slots, and push the counterweight blocks 11 out from top to bottom in turn, and then rotate the rotating part 4 to let the insertion rod 9 rise.

[0036] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0037] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
