Description

Technical Field

[0001] The utility model relates to the field of four-wheeled carts, in particular to a baffle stabilizing and limiting mechanism for a four-wheeled cart. Background Art

[0002] Four-wheeled carts are a common type of transport equipment, widely used in factories, warehouses, and various logistics distribution environments. To prevent materials from slipping or shifting during loading and unloading, carts are often equipped with baffles. These baffles are particularly effective for materials that require stable placement. However, traditional baffle structures have some shortcomings in practical applications.

[0003] First, traditional baffles typically rely on additional retaining devices, such as bolts, locks, or other snap-on structures, to ensure they remain stable when opened. These retaining devices not only increase the complexity of the cart but are also cumbersome to operate during actual use. Repeated installation and removal of the retaining devices can compromise operational efficiency, especially during frequent loading and unloading. Furthermore, with frequent use, traditional retaining mechanisms can become loose, reducing their stability and compromising the safety of materials. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides a four-wheeled cart baffle stabilization and limiting mechanism, which realizes the stable limiting of the baffle in the open state by arranging a rotation tensioning mechanism between the baffle and the cart body.

[0005] The utility model is realized by the following technical solutions: a four-wheeled cart baffle stabilization and limiting mechanism, comprising:

[0006] A cart body, wherein rollers are provided at the bottom of the cart body and a cart handle is provided on one side of the cart body;

[0007] A baffle is rotatably mounted on the other side of the cart body, and the baffle can be rotated relative to the cart body so as to fit the cart body or be perpendicular to the cart body;

[0008] A rotational tensioning mechanism is provided between the baffle and the cart body. When the baffle is opened relative to the cart body, the baffle is tightened by the rotational tensioning mechanism so that the baffle remains in an opened state relative to the cart body.

[0009] As a preferred technical solution, the rotating tensioning mechanism includes a tensioning block, which is fixedly mounted on both sides of the baffle and hingedly arranged on two connecting shafts on the cart body.

[0010] As a preferred technical solution, an elastic gasket is provided on the connecting shaft, and the elastic gasket is sleeved on the connecting shaft. An elastic block is provided on the side of the elastic gasket opposite to the cart body. When the tightening block actively rotates relative to the cart and causes the baffle to open, the tightening block squeezes the elastic block and the elastic gasket, and generates an elastic rebound force to tighten the tightening block.

[0011] As a preferred technical solution, a hinge hole is provided on the connecting shaft, the tensioning block is hinged to the connecting shaft via a bolt, and a locking nut is installed on the bolt.

[0012] As a preferred technical solution, the elastic gasket is made of a metal material that is elastic and has a special-shaped curved surface.

[0013] As a preferred technical solution, the elastic block is made of elastic rubber material.

[0014] The beneficial effects of the present utility model are as follows: the present utility model provides a four-wheeled cart with a baffle stabilization and limiting mechanism. By providing a rotating tensioning mechanism between the baffle and the cart body, the baffle is stably limited in the open state. Unlike traditional structures, the baffle of the present utility model automatically limits its position by utilizing the rotating tensioning mechanism after opening, eliminating the need for additional fixing devices, resulting in a simplified structure and more convenient operation. The rotating tensioning mechanism generates a rebound force through the interaction between the tensioning block and the elastic gasket, thereby stabilizing the baffle and ensuring that it remains in the open state during loading, thereby improving loading and unloading efficiency and material safety.

[0021] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] like Figure 1-Figure 3 As shown, in a specific embodiment of a baffle stabilization and limiting mechanism for a four-wheeled cart of the present invention, the cart body 1 is the main structure of the four-wheeled cart, and a plurality of rollers 3 are installed at the bottom thereof so that the cart can move flexibly. At the same time, a cart handle is provided on one side of the cart body 1 to facilitate users in pushing and pulling the cart. A baffle 2 is installed on the other side of the cart body 1. The baffle 2 is connected to the cart body 1 by rotation so that it can be freely converted between a folded state that fits the cart body 1 and an open state that is perpendicular to the cart body 1. The main function of the baffle 2 is to act as a limit when loading materials, preventing the materials from sliding due to the movement of the cart.

[0024] To ensure that the baffle 2 remains stable after opening, a rotational tensioning mechanism is installed between the baffle 2 and the cart body 1. This mechanism automatically tightens after the baffle 2 is opened, keeping the baffle 2 stable in its open position relative to the cart body 1 without the need for additional fixing structures. The rotational tensioning mechanism includes multiple components, one of the most important of which is the tensioning block 8. The tensioning block 8 is fixedly mounted on both sides of the baffle 2 and hingedly attached to two connecting shafts 6 on the cart body 1. The connecting shafts 6 not only support the rotation of the tensioning block 8 but also, through the structural design of the tensioning block 8, realizes the position limiting function of the baffle 2.

[0025] In the specific design, an elastic washer 5 is mounted on the connecting shaft 6. This washer 5 is fitted onto the connecting shaft 6, and an elastic block 4 is positioned between it and the cart body 1. When the baffle 2 is opened relative to the cart body 1 via the tensioning block 8, the tensioning block 8 compresses the elastic washer 5 and the elastic block 4, generating an elastic rebound force between the elastic block 4 and the elastic washer 5. This rebound force acts on the tensioning block 8, subjecting it to continuous tension, thereby maintaining a stable open position for the baffle 2. This effectively limits the position of the baffle 2 even during movement, preventing materials from slipping.

[0026] To ensure a secure connection between the tension block 8 and the connecting shaft 6, a hinge hole is provided on the connecting shaft 6, and the tension block 8 is hinged to the connecting shaft 6 via a bolt 7. A locking nut is also mounted on the bolt 7 to prevent the hinged connection between the tension block 8 and the connecting shaft 6 from loosening, further enhancing the reliability of the mechanism.

[0027] The elastic gasket 5 is made of a flexible, curved metal material, ensuring sufficient elastic rebound force during tensioning while resisting structural deformation, enhancing durability. The elastic block 4 is made of a resilient rubber material. The rubber's flexibility further enhances the elastic rebound force of the tensioning block 8, effectively adapting to the frequent opening and closing of the baffle 2 during actual use, ensuring that the baffle 2 remains in a stable position after each opening.

[0028] Through this design, the stabilization and limiting mechanism of the baffle plate 2 of the four-wheeled cart of the utility model can automatically limit the position after the baffle plate 2 is opened, without the need for other complex fixing structures. While simplifying the overall structure, it improves the convenience of operation and is suitable for cart loading and unloading scenarios that require frequent opening and closing of the baffle plate 2.

[0029] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
