Description

Technical Field

[0001] This utility model relates to a flatbed cart, and more specifically, to a novel foldable and storage-type multifunctional flatbed cart. Background Technology

[0002] Flatbed trucks are a common type of vehicle for freight transport because they are convenient for loading and unloading large and heavy goods, and can carry more cargo than other types of vehicles of the same specifications, making them popular with transportation companies.

[0003] Existing handcarts and flatbed trucks still occupy a large amount of floor space when the goods are unloaded, which is not conducive to transferring and transporting goods in small spaces such as elevators and car trunks.

[0004] To address the aforementioned issues, an existing folding mechanism for a flatbed cart, disclosed in CN221477158U, includes a flatbed body and a fixed base. The fixed base is symmetrically arranged on both sides of the flatbed body. A first connecting rod is slidably connected to the fixed base, and a hinge rod is rotatably connected to the fixed base. The hinge rod is fixedly connected to the first connecting rod, and the sliding of the first connecting rod is related to the rotation of the hinge rod.

[0005] In the above-described scheme, the first link on the flatbed truck mounting base can slide up and down to limit or release the handlebars. The hinge rod on the mounting base is connected to the first link as a whole, so when the first link slides up and down, it can only move synchronously on both sides. The hinge rod can only rotate on a fixed axis on the mounting base. No matter where the force is applied to the first link, both sides of the first link can move downwards simultaneously, making it easier to fold the flatbed truck handlebars.

[0006] However, the aforementioned flatbed truck can only fold the entire flatbed body. The overall structure and components are still located on the flatbed body, occupying a large amount of planar space. It cannot solve the problem of occupying a large amount of planar space, which is not conducive to the transfer and transportation in narrow spaces, such as elevators and car trunks. It is still not space-saving for staff and users. Utility Model Content

[0024] A new type of foldable, multi-functional flatbed cart, referenced Figures 1-7 The vehicle includes a vehicle body, handles and several wheels mounted on the vehicle body. The vehicle body also includes a foldable first storage plate 1 and a second storage plate 2. The handles are detachably connected to the first storage plate 1, and several wheels are detachably connected to the first storage plate 1 and the second storage plate 2 respectively. The first storage plate 1 and the second storage plate 2 are each provided with a storage rack 10 for fixing the handles and several wheels. The first storage plate 1 and the second storage plate 2 are rotatably connected by a pivot 17. The first storage plate 1 is provided with a fixing structure for fixing the second storage plate 2. The fixing structure includes a sliding block 18 slidably connected in the first storage plate 1, a spring 21 abutting between the sliding block 18 and the first storage plate 1, and a button 3 fixedly connected to the sliding block 18. The second storage plate 2 has a fixing groove 19 for the sliding block 18 to be inserted into. At the same time, two sets of fixing structures can be symmetrically arranged. For details, please refer to the attached drawings in the instruction manual. The first storage plate 1 has a groove 20 inside for the spring 21 and the sliding block 18 to move. The spring 21 is fixedly connected between the sliding plate and the second storage plate 2. The button 3 is T-shaped and has anti-slip texture. The handle includes a first bracket 8 rotatably connected to the first storage plate 1, a tension rod 5 detachably connected to the first bracket 8, and a pull plate 6 fixedly connected to the tension rod 5; The first bracket 8 has a first slot 13 for inserting the tension rod 5. The tension rod 5 has a first spring block 9 symmetrically arranged at one end near the first bracket 8. The side wall of the first slot 13 has a slot for the first spring block 9 to be inserted. The first bracket 8 has a spring piece 7 for pressing the first spring block 9. Each of the wheels includes a second bracket 11 and a wheel body 4 rotatably connected to the second bracket 11. The outer wall of the wheel body 4 is in contact with the inner wall of the storage rack 10. Two sets of fixing frames 14 corresponding to the second bracket 11 are respectively provided on the first storage plate 1 and the second storage plate 2. The fixing frame 14 includes four frames corresponding to the wheels. When the wheel is inserted into the fixing frame, it is flush with the inner wall of the fixing frame. When the first storage plate and the second storage plate are closed together by rotation, the wheel will not protrude outward and affect the closing of the first storage plate and the second storage plate. Meanwhile, the second bracket 11 has a second slot 12 inside for the fixing frame 14 to be inserted. The fixing frame 14 has a protruding hook 15 with elasticity. When the fixing frame 14 corresponds to the second bracket 11, the hook 15 is inserted into the second slot 12.

[0025] The fixed frame 14 is also equipped with table legs 22, and expansion switches 23 are installed on the table legs 22.

[0026] Working principle: When the flatbed truck is no longer in use for transporting goods, the staff needs to fold and store the entire vehicle to prevent it from taking up too much space and to prevent it from moving on its own under the influence of external impacts, which could create a dangerous working environment. First, the staff needs to disassemble several wheels at the bottom of the first storage plate 1 and the second storage plate 2. The staff pulls the wheel 4 and the second bracket 11 connected to the wheel 4 until the second bracket 11 and the corresponding fixed frame 14 move away from each other. The hook 15 will retract towards the center of the fixed frame 14 under the pressure of external force until the fixed frame 14 and the second bracket 11 move away from each other. The hook 15 will also disengage from the second slot 12 opened in the second bracket 11. At this time, several wheels are separated from the first storage plate 1 and the second storage plate 2. Then, the wheel 4 is aligned with the storage frame 10 so that the wheel 4 is inserted into the position of the storage frame 10, thus realizing the disassembly and storage of the wheel 4. Then the staff needs to retract the tension rod 5 of the pull rod. The tension rod 5 adopts a structure of several sections and the second spring block in the existing technology to achieve the effect of fixing and stretching. After the tension rod 5 is shortened, the spring piece 7 protruding outside the first bracket 8 is pressed, so that the spring piece 7 presses the first spring block 9. Under the action of external force, the first spring block 9 will retract into the first slot 13 through the slot and pull the entire tension rod 5, so that the tension rod 5 and the pull plate 6 are retracted. Then the tension rod 5 and the pull plate 6 are placed on the second storage plate 2, and the position of the slot opened on the pull plate 6 is aligned with the position of one of the fixing brackets 14 on the second storage plate 2, so that the position of the pull plate 6 and the fixing bracket 14 is fixed, and the pull rod is disassembled and stored. Finally, the staff can slide the button 3 located on the side of the first storage plate 1 and the second storage plate 2. The staff's fingers can contact the anti-slip texture of the button 3 to achieve an anti-slip effect. With the staff's drive, the button 3 can drive the sliding block 18 to slide in the groove 20, while compressing the spring 21 in the groove 20 until the sliding block 18 separates from the fixing groove 19 on the other side, realizing the removal of the fixed state between the first storage plate 1 and the second storage plate 2. The staff can then rotate the first storage plate 1 and the second storage plate 2, so that the pivot 17 between the first storage plate 1 and the second storage plate 2 can rotate. In this way, the first storage plate 1 and the second storage plate 2 can be put together for storage. At the same time, a handle 16 will be formed between the first storage plate 1 and the second storage plate 2 to facilitate the staff to lift and take the entire vehicle body. When the flatbed cart is idle, after folding up the handles and wheels, the staff can also put the first storage plate 1 and the second storage plate 2 together. At this time, first press the button 3 to drive the sliding block 18 into the groove 20, then rotate the first storage plate 1 and the second storage plate 2 together, and then release the pressure on the button 3. The sliding block 18 will then be aligned with the fixing groove 19 at the other end. The spring 21 will gradually push the sliding block 18 until it is locked into the fixing groove 19 under its own elastic force, thus fixing the first storage plate 1 and the second storage plate 2. Then, spare table legs 22 can be installed on the fixing frame 14, and the fixing frame 14 can be provided with external threads. The table legs 22 are provided with external threads. The matching internal thread groove fixes the table leg 22 by rotation, and the height of the table leg 22 can be adjusted by the mutual extension and retraction of two tubes. At the same time, an expansion switch 23 is set in one of the tubes. By rotating 180 degrees, the two tubes can be locked. The expansion switch can be a nut seat, fixed on one of the tubes. The other tube passes through the tube near the fixing frame 14. The tube in contact with the ground is provided with an external thread matching the expansion switch. By rotating the expansion switch, it can be fixed to the tube, thus fixing the table leg 22. At this time, the flatbed can be used as a table, preventing the flatbed from being idle and thus increasing the practical range of the flatbed. When the flatbed cart is needed, the table legs 22 are disassembled by rotating them. Then, the pull rod is aligned with the first bracket 8, and the tension rod 5 is aligned with the first slot 13 on the first bracket 8. This causes the first spring block 9 to be squeezed and contracted by the inner wall of the first slot 13. When the position of the first spring block 9 corresponds to the slot, the first spring block 9 will be inserted into the slot under its own elastic expansion and contraction to fix the tension rod 5. Then, the staff can adjust the extension length of the tension rod 5. This is also the structure of the traditional tension rod 5 (refer to the pull rod structure of existing flatbed carts and suitcases). Then, several wheels are removed from the storage rack 10, so that the second bracket 11 of the wheel body 4 is aligned with the fixing frame 14. The hook 15 on the fixing frame 14 is inserted into the second slot 12 under the action of the squeezing force, and elastic expansion and contraction are achieved in the second slot 12. The hook 15 will be fully inserted into the second slot 12 until the hook 15 passes through the second slot 12 and contacts the outer wall of the second bracket 11 to achieve a hooking effect. At this time, the installation of the flatbed cart and the subsequent use effect are achieved.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
