Description

Technical Field

[0001] This utility model relates to the field of forklift counterweight devices, specifically to an adjustable counterweight component for forklifts that is easy to assemble. Background Technology

[0002] As a crucial material handling equipment, the stability of forklifts is paramount. Traditional forklifts typically use fixed-weight counterweights (such as cast iron or concrete blocks) to balance the load. However, once manufactured, the weight of these counterweights is not adjustable. This characteristic presents the following drawbacks in practical applications:

[0003] When forklifts need to adapt to different load capacities or operate under different conditions, fixed counterweights cannot be flexibly matched, making it difficult to achieve optimal balance and operational efficiency. Changing the counterweight usually requires replacing the entire counterweight block, which is cumbersome, time-consuming, labor-intensive, and increases maintenance costs. Therefore, there is an urgent need in existing technologies for a forklift counterweight solution that allows for convenient and flexible weight adjustment and efficient assembly. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable counterweight assembly that is easy to assemble, which solves the problem of inconvenient assembly and adjustment of existing forklift counterweight assemblies.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An adjustable counterweight assembly that is easy to assemble includes a housing with a cover on top. Inside the housing are an adjustment component and multiple counterweight parts. Each counterweight part has a through hole in its center for the adjustment component to pass through. The adjustment component includes a rod, a ring at the top of the rod, and a locking block on the outside of the rod. The bottom of each counterweight part has a slot corresponding to the locking block along the circumference of the through hole, and the through hole and the slot are interconnected.

[0007] As a further optimization of this utility model, the locking blocks are evenly distributed along the circumference of the rod, and at least two locking blocks are provided.

[0008] As a further optimization of this utility model, the locking block is fixed to the side wall of the rod.

[0009] As a further optimization of this utility model, the rod body is a screw rod, and an assembly ring is threadedly connected to the outer side of the screw rod. The locking block is fixed on the outer side wall of the assembly ring, and the locking block is located at the lower part of the assembly ring.

[0010] As a further optimization of this utility model, an inner shell is fixedly provided inside the outer shell, and the counterweight component and the adjustment component are both located inside the inner shell. A threaded joint corresponding to the screw is provided on the bottom wall of the inner shell.

[0011] As a further optimization of this utility model, a guide post is provided through the bottom wall of the inner shell, and a conical guide surface is formed on the top of the guide post. The counterweight component is provided with a positioning hole corresponding to the guide post.

[0012] As a further optimization of this utility model, the guide post is provided with an injection channel inside, and the bottom of the side wall of the guide post is provided with an outlet communicating with the injection channel.

[0013] As a further optimization of this utility model, the side wall of the guide post protrudes outward to form a convex ring, which is used to support the bottom wall of the inner shell.

[0014] As a further optimization of this utility model, multiple markers are provided vertically on the side wall of the rod.

[0015] The beneficial effects of this utility model are as follows:

[0016] After the cover of the counterweight component is opened, the counterweight components can be hoisted or the number of components can be adjusted by adjusting the component. The counterweight component is provided with a through hole for the adjusting component to pass through and a slot at the bottom of the through hole. After the adjusting component passes through multiple counterweight components in sequence, the locking block can be screwed into the slot. Then, multiple counterweight components can be disassembled, assembled, and hoisted by adjusting the component, which improves the convenience of counterweight assembly and adjustment of the forklift adjusting component.

[0017] The adjustment component of this utility model can be reused as a fastener. After the counterweight is adjusted, the assembly ring of the adjustment component is screwed up to the top of the rod and the rod is connected to the threaded joint on the inner shell. Then the assembly ring is screwed down to make the locking block press down on the counterweight component, thereby fastening each counterweight component between the locking block and the bottom wall of the inner shell, making the counterweight component structure stable and reliable.

[0018] In this invention, when disassembling and assembling counterweight components, the bottom wall of the inner shell is supported by a guide post, which guides and limits the counterweight components, improving the ease of disassembly and assembly of the counterweight components, aligning the through holes of each counterweight component so as to insert the adjustment component, and the guide post is also used to provide a counterweight medium inlet so as to fill the cavity between the outer shell and the inner shell with the counterweight medium.

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example

[0031] like Figure 1-3 As shown, this embodiment relates to an adjustable counterweight assembly that is easy to assemble. The counterweight assembly is installed at the rear of a forklift vehicle. The counterweight assembly includes a housing 1, with a cover 2 hinged to the top front side of the housing 1. Inside the housing 1 are an adjustment component 3 and multiple counterweight parts 4. Each counterweight part 4 has a through hole 5 in the middle for the adjustment component 3 to pass through, and the bottom of the adjustment component 3 has a slot 6 for engaging the adjustment component 3. The counterweight assembly of this embodiment has an adjustable weight function, and the counterweight parts 4 can be partially or completely placed inside the housing 1.

[0032] Specifically, the adjusting assembly 3 includes a rod 301, a lifting ring 302 fixed to the top of the rod 301, and a locking block 303 disposed on the outer side of the rod 301. The locking blocks 303 are evenly distributed around the circumference of the rod 301. The number of locking blocks 303 can be adjusted according to actual needs; in this embodiment, two locking blocks 303 are provided. In addition, in some other embodiments, the lifting ring 302 can also be rotatably connected to the rod 301. The rod 301 is a screw, and an assembly ring 304 is threadedly connected to the outer side of the screw. The locking blocks 303 are fixed to the outer wall of the assembly ring 304, and the locking blocks 303 are located at the lower part of the assembly ring 304. The counterweight component 4 has a groove 6 corresponding to the locking block 303 along the circumference of the through hole 5 at the bottom. The depth of the groove 6 is not less than the thickness of the locking block 303. The groove 6 is used for the locking block 303 to rotate and engage. The shape of the through hole 5 is consistent with the outer contour of the assembly ring 304 and the locking block 303, allowing the assembly ring 304 and the locking block 303 to pass through. The bottom of the through hole 5 is connected to the groove 6.

[0033] Please see Figure 3-6 After the counterweight assembly cover 2 is opened, the counterweight components 4 can be hoisted or their quantity adjusted via the adjustment assembly 3. Since the counterweight components 4 have through holes 5 for the adjustment assembly 3 to pass through and slots 6 at the bottom of the through holes 5, the adjustment assembly 3 can be rotated until the locking block 303 aligns with the through hole 5. Then, the rod 301 is passed through multiple counterweight components 4 sequentially. Next, the adjustment assembly 3 is rotated again to screw the locking block 303 into the slots 6 at the bottom of the counterweight components 4. Afterwards, multiple counterweight components 4 can be simultaneously disassembled and hoisted using hoisting equipment in conjunction with the adjustment assembly 3, making the counterweight assembly and adjustment of the forklift adjustment assembly 3 more convenient. Additionally, as... Figure 4 As shown, multiple markers 305 are provided vertically on the side wall of the rod 301. The markers 305 are preferably grooves. When the rod 301 is moved downward, the depth of the rod 301 inserted into the counterweight component 4 can be determined by observing the position change of the markers 305 above the counterweight component 4, thereby further improving the convenience of adjusting the weight of the counterweight.

[0034] Furthermore, such as Figure 7 As shown, an inner shell 7 is fixedly installed inside the outer shell 1. The counterweight component 4 and the adjusting component 3 are both located inside the inner shell 7. A threaded joint 8 corresponding to the screw is fixedly installed on the bottom wall of the inner shell 7. Please refer to [link / reference]. Figure 8A guide post 9 is provided through the bottom wall of the inner shell 7. The top of the guide post 9 forms a conical guide surface 10. The counterweight component 4 is provided with a positioning hole 11 corresponding to the guide post 9. An injection channel 12 is provided inside the guide post 9, and an outlet 13 communicating with the injection channel 12 is provided at the bottom of the side wall of the guide post 9. The bottom walls on both sides of the outer shell 1 protrude upward to accommodate the rear wheels of the forklift, and the bottom walls on both sides of the outer shell 1 are also in contact with the bottom wall of the inner shell 7, providing a certain degree of support for the inner shell 7. The bottom wall of the inner shell 7 is provided with an insertion hole corresponding to the guide post 9. The side wall of the guide post 9 protrudes outward to form a convex ring 14, which is used to support the bottom wall of the inner shell 7. The convex ring 14 is located at the lower edge of the insertion hole on the bottom wall of the inner shell 7. The bottom end of the guide post 9 is fixedly set on the bottom wall of the outer shell 1.

[0035] The adjustment component 3 in this embodiment can be reused as a fastener, such as... Figure 2 and Figure 3 As shown, after the counterweight component 4 is installed or the quantity is adjusted, the assembly ring 304 of the adjusting component 3 is screwed up to the top of the rod 301, and the rod 301 is threadedly connected to the threaded joint 8 on the inner shell 7. Then, the assembly ring 304 is screwed down, so that the locking block 303 presses against the uppermost counterweight component 4, thereby securing each counterweight component 4 between the locking block 303 and the bottom wall of the inner shell 7, making the structure of the counterweight component more stable and reliable.

[0036] During the assembly and disassembly of counterweight components 4, the convex ring 14 of the guide post 9 strengthens the support for the bottom wall of the inner shell 7. The guide post 9 also guides and limits the counterweight components 4, improving the ease of assembly and disassembly and ensuring that the through holes 5 of each counterweight component 4 are aligned, thus ensuring that the adjusting assembly 3 can be smoothly inserted into each counterweight component 4. Furthermore, a cavity is formed between the outer shell 1 and the inner shell 7, which is used to fill counterweight media such as concrete. The guide post 9 also provides an inlet for the counterweight media, allowing the counterweight media to be filled into the cavity between the outer shell 1 and the inner shell 7. The upper end of the injection channel 12 is the counterweight media inlet.

[0037] When filling the counterweight assembly with counterweight medium, the counterweight medium is poured into the injection channel 12 from the top of the guide post 9, and flows out from the outlet 13 at the bottom of the guide post 9, thereby filling the cavity of the counterweight assembly. This ensures that the counterweight assembly has sufficient weight while maintaining adjustable weight, and facilitates the filling of the counterweight medium, further improving the ease of assembly. Alternatively, in some other embodiments, the guide post 9 may not be provided, or only a guide structure without a counterweight medium filling function may be provided, such as a solid guide rod or guide rail.

[0038] Furthermore, in some other embodiments, the adjustment component 3 may only have a fixed locking block 303, without the assembly ring 304 as described in the previous embodiments. Please refer to... Figure 9 , Figure 9 Another embodiment of the adjustment assembly 3 is shown. This assembly also includes a rod 301, a lifting ring 302 fixed to the top of the rod 301, and multiple locking blocks 303. The rod 301 has no threads, and the locking blocks 303 are fixedly mounted on the side wall of the rod 301. This adjustment assembly 3 does not function to fasten the counterweight components 4, but it can adjust the number of counterweight components 4, allowing multiple counterweight components 4 to be installed or removed simultaneously.

[0039] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of this utility model.
