Description

Technical Field

[0001] This utility model relates to a modularly assembled forklift frame structure. Background Technology

[0002] In the traditional forklift manufacturing industry, forklift frames typically employ a one-piece welded structure or integral casting process. While this design offers a certain level of structural strength and stability, it presents numerous limitations in production, transportation, maintenance, and functional expansion. For instance, one-piece frames are bulky and heavy, increasing raw material consumption and raising transportation and warehousing costs. This is particularly problematic for export-oriented companies, where high logistics costs significantly impact product competitiveness. Currently, although some forklifts are attempting to adopt a modular design, the degree of modularity is insufficient. Connections often rely on bolt fastening or simple splicing, resulting in insufficient overall rigidity, susceptibility to loosening, and difficulty in meeting the demands of high-intensity operations. Therefore, a new type of modular forklift frame structure is urgently needed. Through standardized, lightweight modular design, it can achieve rapid assembly, convenient maintenance, and functional expansion, while ensuring structural stability and load-bearing capacity.

[0010] The beneficial effects of this utility model are:

[0011] (1) The modular forklift frame structure of this utility model achieves rapid assembly and disassembly through the standardized design of side mounting plates, front baffles, tail plates and vertical rods.

[0024] Reference Figure 1-4 As shown, a modularly assembled forklift frame structure includes...

[0025] The side mounting plate 10 has an L-shaped side rod 100 on its inner side, and a connecting hole 104 is formed on the L-shaped side rod 100. A positioning member 102 is provided at the end of the L-shaped side rod 100 to enhance the connection end strength of the vertical rod 40.

[0026] Furthermore, in this embodiment, the positioning member 102 can also be an elastic fastener (an existing structure, which will not be described in detail here). For example, a pin is provided at the end of the vertical rod 40. After the connecting rod 4008 on the vertical rod 40 is inserted into the connecting hole 104, the positioning member 102 is subjected to force and bends backward until the connecting rod 4008 and the connecting hole 104 are fully connected. Then the positioning member 102 is connected to the pin, so that the end of the vertical rod 40 will not break, thereby ensuring the strength of the overall structure.

[0027] An overlapping rod 106 is provided on the inner side of the side mounting plate 10 away from the L-shaped side rod 100. The overlapping rod 106 is connected to the overlapping interface 2020 symmetrically formed on the overlapping plate 202.

[0028] The front baffle 20 has mounting portions 2000 on both sides; strip plates 2002 are also provided at the edges of both sides of the front baffle 20; and several reinforcing ribs are provided on the strip plates 2002. In one embodiment, the reinforcing ribs of the strip plates 2002 adopt a wavy or honeycomb structure to balance weight reduction and impact resistance.

[0029] Tail plate 30 is positioned between the two side mounting plates 10.

[0030] The vertical rod 40 has a connecting rod 4008 fixedly installed at one end, which is inserted into the connecting hole 104. A load-bearing bent rod 4004 for supporting the ceiling component is installed in the hollow groove 4002 in the middle of the vertical rod 40. The bent rod 402 at the other end of the vertical rod 40 has an assembly hole 4022 that is connected to the mounting part 2000. The ceiling component includes a horizontal rod 404 and an intermediate support rod 406 installed between the vertical rod 40 and the bent rod 402. A connector 4020 is also installed on the bent rod 402.

[0031] The outer wall of the connecting rod 4008 of the vertical rod 40 is covered with an anti-loosening rubber sleeve (not shown in the figure), and the inner wall of the connecting hole 104 is provided with matching anti-slip texture. The anti-loosening rubber sleeve is a layered conformal mechanism, including an outer layer, a middle layer, and an inner layer. Specifically, the outer layer is made of wear-resistant nylon or polyurethane material, with a surface processed into fish-scale-like protrusions to increase the coefficient of friction; the middle layer is an elastic silicone layer, 2-3 mm thick, providing cushioning and deformation compensation; and the inner layer is a metal skeleton that is interference-fitted with the connecting rod 4008 to prevent circumferential rotation of the rubber sleeve. Therefore, compared to ordinary smooth rod connections, this embodiment has better anti-loosening capabilities.

[0032] Working principle: The frame is supported by the side mounting plates 10 on both sides. The L-shaped side rods 100 are connected to the vertical rods 4008 via connecting holes 104, and locked by positioning pieces 102. Simultaneously, the overlapping rods 106 on the inner side of the side mounting plates 10 connect to the overlapping interface 2020 of the front baffle 20, forming a laterally stable structure. The front baffle 20 is fixed by connecting the side mounting parts 2000 to the assembly holes 4022 of the bent ends 402 of the vertical rods 40. The strip plates 2002 are further reinforced... The robust design ensures connection strength; the tail plate 30 connects laterally to the mounting plates 10 on both sides to form a complete frame; the load-bearing bent bar 4004 in the middle of the vertical bar 40 supports the roof structure composed of the horizontal bar 404 and the intermediate support bar 406, and the connector 4020 enables the rapid installation of the roof; each connection part is designed with anti-loosening rubber sleeves and anti-slip textures to ensure the stability of the connection, so that the entire frame can achieve modular rapid disassembly and assembly, convenient transportation and maintenance, and flexible expansion of functional components according to needs while ensuring structural strength.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
