Description

Technical Field

[0001] The utility model relates to the technical field of pallet truck forks, and specifically relates to a reinforced fork for a pallet truck. Background Art

[0002] Facing the increasingly developing logistics industry, as an important handling tool, the operating conditions and working intensity of pallet trucks have attracted increasing attention from users. As the carrier that directly contacts the pallet during handling, the fork should meet the requirements of strength, stiffness, and durability to reliably handle goods. In addition, the fork should also facilitate access to and from the pallet.

[0003] Existing pallet truck forks mostly adopt thick plate welded forks or formed forks. Formed forks have advantages in terms of cost and efficiency for mass production. However, this production method also has certain limitations, especially in the selection of plate thickness. If the plate is too thin, the fork may lack strength and cannot withstand the pressure during handling; while if the plate is too thick, difficulties will be encountered during the forming process because the greater the plate thickness, the greater the force required for bending or shaping, which not only requires higher mechanical properties but also affects the accuracy after forming, thus restricting the selection of plate thickness. Therefore, it is necessary to design a reinforced fork for a pallet truck. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a reinforced fork for a pallet truck to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A reinforced fork for a pallet truck includes a fork body. A receiving cavity for a fixed rear reinforcement plate and a front reinforcement plate is formed in the part of the fork body close to the ground. The rear reinforcement plate is connected to the front reinforcement plate. The end of the rear reinforcement plate away from the front reinforcement plate is connected to the vehicle body through a support. A guide block is provided on the end face of the fork body close to the ground, and the guide block is located on the other side of the fork body away from the support.

[0006] As a further scheme of the utility model: The end of the front reinforcement plate away from the rear reinforcement plate forms an inclined part flush with the bottom of the fork body.

[0007] As a further scheme of the utility model: The end of the rear reinforcement plate away from the front reinforcement plate forms a first notch adapted to the connection part with the support.

[0008] As a further scheme of the utility model: The support includes two vertical plates and a connecting rib connecting the two vertical plates. Second notches are provided at the ends of the two vertical plates away from the connecting rib, and second pin holes are designed to penetrate the surfaces of the two vertical plates in the horizontal direction.

[0009] As a further solution of the present invention: a clamping block adapted to the bottom of the fork body is installed at the end of the guide block, and the end surface of the guide block away from the clamping block is designed to be a multi-arc surface.

[0010] As a further solution of the present invention: a left plate and a right plate are respectively installed at the end of the fork body adjacent to the guide block, and a first pin shaft hole for the pin shaft to pass through is opened on the left plate and the right plate. A through hole is also opened on the left plate and the right plate, and an elastic pin is installed in the through hole to limit the rotation of the pin shaft in the first pin shaft hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Under the action of the rear reinforcement plate and the front reinforcement plate, this application is used to increase the rigidity and strength of the fork body on the one hand, and on the other hand, its weight is used to increase the load on the front wheel in the unloaded state, and lower the center of gravity to increase high-speed driving stability, indirectly reducing the thickness of the fork plate, and in cooperation with the guide block, it is convenient for the auxiliary fork to enter the interior of the pallet.
