Description

Technical Field

[0001] This utility model belongs to the field of luggage cart technology, and specifically relates to a folding hand-pulled luggage cart. Background Technology

[0002] Hand-held luggage carts are widely used in daily life, especially in shopping and travel. To facilitate carrying and storage, various foldable hand-held luggage carts have appeared on the market.

[0003] Traditional folding luggage carts typically have complex folding mechanisms that require multiple steps from the user. Some luggage carts, after being folded, fail to fully retract their wheels, brackets, and other components, resulting in a loose structure, large space occupation, and limited portability improvement. To address these issues, we offer a folding hand-pulled luggage cart. Utility Model Content

[0004] The purpose of this utility model is to provide a folding hand-pulled luggage cart to solve the problems mentioned in the background art. The folding mechanism of traditional folding luggage carts is usually more complicated, requiring users to perform multiple steps. After folding, some luggage carts fail to fully fold their wheel sets, brackets and other components, resulting in a loose structure, large space occupation and limited improvement in portability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a folding hand-pulled luggage cart, including a base, brackets rotatably connected to both sides of the bottom of the base, and support members rotatably connected to both sides of the back of the base. A first pull rod is fixedly connected inside the support member, a first handle is fixedly connected to the top of the first pull rod, a connector is slidably sleeved on the surface of the first pull rod, a second pull rod is fixedly connected to the top of the connector, a second handle is fixedly connected to the top of the second pull rod, a movable wheel is rotatably connected to one side of the bracket, a deformable end is integrally machined on the top of the support member, a slot is formed on the top of the deformable end, and a limiting block adapted to the slot is integrally machined on the bottom of the base.

[0006] Preferably, the bottom of the support member is integrally machined with an arc-shaped end, one side of the support member is integrally machined with a limiting plate, and the bottom of the base is integrally machined with a limiting groove that matches the limiting plate.

[0007] Preferably, the base has a first locking block integrally machined on both sides of its bottom, and the connector has a second locking block integrally machined on its top.

[0008] Preferably, the first handle has two connecting rods rotatably connected inside, a button is sleeved at the bottom of the first handle, one end of each connecting rod passes through the inside of the button, two springs are sleeved inside the button, and a top cover is fixedly connected to the top of the first handle.

[0009] This utility model has the following beneficial effects: This device allows the second pull rod to slide the connecting piece on the surface of the first pull rod by pressing the second handle. This causes the bottom of the connecting piece to press against the deformable end, which in turn causes the deformable end to release the locking slot from the limiting block. Then, the base is folded in the opposite direction. At the same time, the bracket drives the moving wheels to rotate towards the base, and the first locking block engages with the first pull rod. Meanwhile, the first pull rod limits the bracket. Thus, while ensuring structural stability and reliability, the entire luggage cart can be folded quickly and smoothly. The device is ingeniously designed with coordinated linkage of all components, which greatly improves ease of use. In addition, the folded structure is compact, making it easy to carry and store. It has the advantages of simple operation and space saving. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Example 1: refer to Figure 1-6A folding hand-pulled luggage cart includes a base 1, brackets 2 rotatably connected to both sides of the bottom of the base 1, support members 3 rotatably connected to both sides of the back of the base 1, a first pull rod 4 fixedly connected inside the support member 3, a first handle 5 fixedly connected to the top of the first pull rod 4, a connector 6 slidably sleeved on the surface of the first pull rod 4, a second pull rod 7 fixedly connected to the top of the connector 6, a second handle 8 fixedly connected to the top of the second pull rod 7, a movable wheel 9 rotatably connected to one side of the bracket 2, a deformable end 10 integrally machined on the top of the support member 3, a slot 11 formed on the top of the deformable end 10, and a limiting block 15 adapted to the slot 11 integrally machined on the bottom of the base 1.

[0014] Specifically, the device works by pressing the second handle 8, causing the second pull rod 7 to slide the connecting piece 6 on the surface of the first pull rod 4. This causes the bottom of the connecting piece 6 to press against the deformable end 10, which in turn causes the deformable end 10 to release the locking groove 11 from the limiting block 15. The base 1 then folds in the opposite direction. Simultaneously, the bracket 2 drives the moving wheel 9 to rotate towards the base 1, causing the first locking block 16 to engage with the first pull rod 4. At the same time, the first pull rod 4 limits the bracket 2. This ensures a stable and reliable structure while achieving a fast and smooth folding operation for the entire luggage cart. The device is ingeniously designed with coordinated linkages among its components, significantly improving ease of use. Furthermore, the folded structure is compact, making it easy to carry and store, and it offers the advantages of simple operation and space saving.

[0015] refer to Figure 4 and Figure 5 The bottom of the support member 3 is integrally machined with an arc-shaped end 12. By setting the arc-shaped end 12, when the device is unfolded, the arc-shaped end 12 pushes the bracket 2 to unfold, which has a good linkage effect. One side of the support member 3 is integrally machined with a limiting plate 13, and the bottom of the base 1 is integrally machined with a limiting groove 14 that matches the limiting plate 13. By setting the limiting plate 13 and the limiting groove 14, when unfolded, the limiting plate 13 is inserted into the interior of the limiting groove 14, so that the support member 3 can effectively abut and limit the bracket 2.

[0016] refer to Figure 6 Both sides of the bottom of the base 1 are integrally machined with first locking blocks 16. By setting the first locking blocks 16, the first pull rod 4 can be effectively locked and limited. The top of the connector 6 is integrally machined with a second locking block 17. By setting the second locking block 17, the second locking block 17 can be limited by the connecting rod 18.

[0017] refer to Figure 6The first handle 5 has two connecting rods 18 rotatably connected inside. A button 19 is fitted at the bottom of the first handle 5. One end of the connecting rod 18 passes through the inside of the button 19. Two springs 20 are fitted inside the button 19. A top cover 21 is fixedly connected to the top of the first handle 5. Pressing the button 19 causes the springs 20 to compress. At the same time, the button 19 causes one end of the connecting rod 18 to lift up, and the other end of the connecting rod 18 releases the limit on the second locking block 17.

[0018] Brief description of usage: The user can press button 19 to compress spring 20. At the same time, button 19 lifts one end of connecting rod 18, and the other end of connecting rod 18 releases the restriction on second locking block 17. Pressing the second handle 8 causes the connecting piece 6 to slide on the surface of the first pulling rod 4 through the second pull rod 7, so that the bottom of the connecting piece 6 presses the deformable end 10, causing the deformable end 10 to drive the slot 11 to release the restriction on the limiting block 15. Then, the base 1 is folded in the opposite direction. At the same time, the bracket 2 drives the moving wheel 9 to rotate towards the base 1, so that the first locking block 16 engages with the first pull rod 4, and the first pull rod 4 limits the bracket 2, thereby enabling the device to be folded quickly.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
