Description

Technical Field

[0001] This utility model relates to the field of cargo vehicle frame technology, specifically a foldable cargo vehicle frame. Background Technology

[0002] A cargo frame is a key component used to carry and load goods. There are various types to suit different cargo-carrying scenarios. One common type is the cargo frame mounted on the truck door panel. This type of frame is equipped with hooks for securing cargo. In practical use, when the truck's deck area is already full, adding this door panel cargo frame can effectively expand the truck's cargo space, meeting the transportation needs of more goods without requiring additional transport vehicles, thus greatly improving the flexibility and convenience of cargo transportation.

[0003] However, most load-bearing components such as hooks on existing cargo cart frames are fixed to the main frame by welding. Since the hooks need to withstand the pulling and friction of the goods for a long time, they are prone to deformation, breakage and other damage during frequent use. Because the welded structure cannot be disassembled, once the hooks or other components are damaged, the entire cargo cart frame must be disassembled and replaced. This not only greatly increases the cost of using the equipment, but also causes other intact parts on the frame to be discarded, resulting in serious waste of resources and making it difficult to meet the needs of efficient and economical use.

[0037] Example

[0038] Please see Figures 1-9 The present invention provides the following technical solution: a foldable cargo rack, including a main frame plate 1, with snap-fit ​​plates 2 fixed at both ends of the main frame plate 1, and the two snap-fit ​​plates 2 distributed on the same side; a fixing plate 3 is fixed at both ends of the bottom of the main frame plate 1, and a fastening bolt 4 is threadedly connected to the fixing plate 3, and a buffer pad 24 is provided at the end of the fastening bolt 4 close to the snap-fit ​​plate 2;

[0039] It also includes a pair of detachable hook plates 9, a folding mechanism, and an adjustment mechanism;

[0040] Both hook plates 9 are mounted on the folding mechanism. The folding mechanism is rotatably mounted on the main frame plate 1 via the rotating plate 6 it contains, for folding and storing the hook plates 9. An L-shaped frame plate 7 is connected to the rotating plate 6.

[0041] An adjustment mechanism is mounted on the folding mechanism and connected to the hook plate 9, allowing the two hook plates 9 to move towards or away from each other, thereby changing the distance between the two hook plates 9 and fixing them after the position is changed; a main hook 10 is provided at the bottom end of the hook plate 9.

[0042] During installation, the two snap-fit ​​plates 2 on the device are snapped onto the inside of the truck door panel, and the installation is completed by tightening the two fastening bolts 4 clockwise. The operation is simple and convenient.

[0043] Preferably, by Figure 1 , Figure 3 and Figure 9 As shown, in this embodiment, a U-shaped frame plate 17 is provided on the main frame plate 1, and a worm gear 19 is rotatably mounted on the U-shaped frame plate 17. A worm wheel 18, meshing with the worm gear 19, is fixed on the rotating shaft of the rotating plate 6. One end of the worm gear 19 extends to the outside of the U-shaped frame plate 17 and is fixed with a second operating disc 20. A notch 16 for the rotating plate 6 to be inserted is provided on the main frame plate 1. When the device is idle, simply rotate the second operating disc 20 clockwise, and the worm gear 19 drives the worm wheel 18 to rotate, thereby forcing the rotating plate 6, which is fixedly connected to the worm wheel 18, to rotate until the surface of the rotating plate 6 is in contact with the bottom of the notch 16. Figure 9 As shown in the diagram, the structure on the L-shaped frame 7 and the two hook plates 9 can be stored on the other side of the main frame 1 (inside the truck door panel), which facilitates storage and reduces the probability of damage when idle.

[0044] Preferably, by Figures 1 to 3 As shown, in this embodiment, the adjustment mechanism includes a forward and reverse threaded screw 12 rotatably mounted on an L-shaped frame plate 7. One end of the forward and reverse threaded screw 12 is fixedly connected to an operating disc 14. The forward and reverse threaded screw 12 is threaded with symmetrically distributed threaded connecting plates 15. The two threaded connecting plates 15 can move closer or further apart from each other through the forward and reverse threaded screw 12.

[0045] The main frame plate 1 is provided with symmetrically distributed guide rods 13, and each of the two threaded connecting plates 15 is pre-set with through holes that slide with the guide rods 13. This arrangement facilitates the adjustment of the distance between the two hook plates 9 according to the loaded goods. When adjusting, simply rotate the No. 1 operating disc 14 clockwise, and the two threaded connecting plates 15 will move towards each other through the positive and negative thread screws 12, thereby reducing the distance. Conversely, rotating the No. 1 operating disc 14 counterclockwise can increase the distance between the two hook plates 9.

[0046] Preferably, by Figures 4 to 6 As shown, in this embodiment, two threaded connecting plates 15 are each fixed with a U-shaped connecting plate 21 on one side facing the L-shaped frame plate 7, and the L-shaped frame plate 7 is provided with an adjustment elongated hole 8 for the U-shaped connecting plate 21 to move.

[0047] The end face of the U-shaped connector 21 is provided with a mounting plate 22, and an insertion elongated hole 25 is provided on the mounting plate 22. The top of the hook plate 9 is provided with an insertion plate 26 that matches the insertion elongated hole 25. Both the U-shaped connector 21 and the insertion plate 26 are pre-set with threaded holes, and a hand-tightening bolt 23 is screwed into the internal thread. If the hook plate 9 is damaged during use, the hand-tightening bolt 23 can be removed by turning counterclockwise to replace it, without having to replace the whole thing, thus reducing costs.

[0048] Preferably, by Figure 6 and Figure 7 As shown, in this embodiment, the hook plate 9 is provided with a plurality of equally spaced sub-hooks 11;

[0049] The hook plate 9 has equidistantly distributed mounting holes 27, and the secondary hook 11 has a snap connector 28 that mates with the mounting holes 27. The snap connector 28 is elastic. The design of the secondary hook 11 further increases the storage space of the device, and its detachable design also facilitates subsequent maintenance and replacement.

[0050] Preferably, by Figure 3 and Figure 8 As shown in this embodiment, the fastening bolt 4 is provided with a snap-fit ​​block 29, and the buffer pad 24 is provided with a snap-fit ​​groove 30 that matches the snap-fit ​​block 29. During use, if the buffer pad 24 is severely worn, it can be pulled out and replaced for easy maintenance.

[0051] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, a buffer pad 5 is provided on the bottom surface of the horizontal section of the snap-fit ​​plate 2. During installation, the buffer pad 5 will press against the top surface of the truck door panel to achieve the buffering function and reduce wear.

[0052] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
