Description

Technical Field

[0001] This utility model relates to a transfer vehicle, specifically a cargo transfer vehicle. Background Technology

[0002] Freight transport is one of the main modes of modern transportation, therefore transport vehicles occupy an important position in the entire transportation field and are indispensable transportation equipment in human life. Since transport vehicles cannot directly enter and unload goods, freight transfer carts are needed for final transfer into the warehouse. After use, freight transfer carts are relatively large and require a lot of space, especially when the transfer carts need to be loaded onto the transport vehicle, which greatly limits the vehicle's loading capacity. Therefore, detachable and foldable carts have been designed. However, existing foldable carts have the following problems: First, the goods are directly piled on the transport vehicle. Since the goods are not secured, they are prone to shaking when encountering potholes or rugged mountain roads, posing a risk of scattering.

[0003] Secondly, due to the use of solid board material, it is quite heavy when folded, making it inconvenient to handle manually after folding.

[0004] Third, existing folding carts mainly fold the frame. The handlebars or wheels cannot be folded, and the folded size is still relatively large. Or, some folding carts have handlebars that can rotate to a certain angle, but the handlebars are movable relative to the cart. So when moving the cart, the handlebars are easy to flip and rotate, making it inconvenient to move. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a cargo transfer vehicle with a simple structure that securely places goods on the vehicle for easy transport.

[0031] The working principle of this utility model: When goods are placed on the frame, they are secured by two binding straps 13 that are cross-laid on the frame, making the goods more stable.

[0032] When the wheel assembly 2 engages with the locking groove on the mounting base via the boss on the locking sleeve, the wheel assembly is secured to the wheel mounting bracket. When the wheel assembly 2 needs to be folded, simply push the locking sleeve backward to separate the boss on the locking sleeve from the locking groove on the mounting base, and then rotate the wheel assembly along the support rod to fold it into the third groove.

[0033] When the handrail needs to be folded, the handrail locking mechanism is manually activated. By moving the two fork blocks towards the center with the handle, the fork blocks compress the first telescopic spring, thereby causing the locking rod extending into the first groove to retract into the second groove. After the handrail is folded into the first groove, the handles of the two fork blocks are released, and the locking rod is automatically moved to both sides of the housing by the first telescopic spring, thereby locking the handrail.
