Description

Technical Field

[0001] The present invention relates to the technical field of forklift fork transportation, and particularly to a telescopic fork with a low deflection design. Background Art

[0002] The forklift fork is an attachment of a forklift, equivalent to a manipulator mounted on the forklift, making the forklift a multi-purpose and high-efficiency material handling tool. It can perform operations such as forking, clamping, pushing, pulling, side shifting, and rotating on almost any imaginable handling object, thereby improving logistics efficiency.

[0003] Due to factors such as its large volume, wide width, and long length, conventional forklift forks cannot be well adapted to environments with small spaces. Most factories and enterprises use telescopic forks to adapt to such environments. According to Chinese Patent CN213771227U, a telescopic fork is disclosed. The length of this fork can be changed according to requirements. However, when handling heavy goods such as steel coils, the strength of the fork is insufficient, resulting in the fork bending, and then the heavy object may slip.

[0004] Therefore, it is necessary to develop a telescopic fork with a low deflection design to solve the above problems. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a telescopic fork with a low deflection design that has high strength and is resistant to bending.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A telescopic fork with a low deflection design, which includes:

[0007] A frame body, which forms an empty groove by recessing inward from the surface. A first tooth rail and a transmission gear are arranged in the empty groove;

[0008] A moving track, which extends into the empty groove. The moving track has a second tooth rail, an intermediate gear, and an emptying groove formed by recessing inward from its surface. The transmission gear meshes with the second tooth rail, and the moving track moves along the empty groove;

[0009] A supporting part, which extends into the emptying groove. The supporting part has a third tooth rail. The intermediate gear meshes with the first tooth rail and the third tooth rail respectively, and the supporting part moves along the emptying groove.

[0010] Further, the supporting part is an L-shaped plate body. The top of the supporting part is perpendicular to the bottom of the supporting part, and the top of the supporting part is buckled on the top of the moving track.

[0011] Further, the moving track has a groove formed by recessing inward from the inner wall of the emptying groove, and the groove is used to guide the supporting part.

[0012] Further, several limiting members and several rollers are provided on one side of the supporting portion, and the several limiting members and the several rollers extend into the groove.

[0013] Further, the height of the moving track is greater than the width of the moving track.

[0014] Further, a support frame is installed on the upper surface of the supporting portion, and the support frame is used to support goods.

[0015] Further, the support frame is an L-shaped plate, the bottom of which is fixedly connected to the upper surface of the supporting portion, and the top of which extends vertically upward.

[0016] Further, a notch is formed by the upper surface of the support frame being recessed inward, and the notch is used to carry goods.

[0017] Further, the upper surface of the support frame slopes obliquely downward from both ends to the notch.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model is a telescopic fork with a low deflection design, having the characteristics of high strength and anti-bending. The passive gear drives the movement of the moving track by meshing with the driving gear, and the intermediate gear moves accordingly. It meshes with the second tooth track and the third tooth track respectively, driving the supporting portion to move to a predetermined position, and then lifting the goods by other equipment. It can adapt to environments with relatively small spaces. At the same time, the moving track moves and supports in a relatively narrow form within the frame body, and the supporting portion moves in a relatively narrow form within the moving track, increasing the thickness of the telescopic fork, improving the strength, and reducing the occurrence of bending of the fork.
