Description

Technical Field

[0001] This application relates to the field of trailers, and in particular to a box trailer. Background Technology

[0002] A trailer is a non-powered vehicle that needs to be towed by a tractor (such as a truck, pickup truck, or SUV) for transporting goods, equipment, or other special purposes.

[0003] Traditional trailers primarily use flatbed structures for their cargo platforms, such as the off-road suitable trailer chassis disclosed in CN107554613B and the safe, non-powered trailer structure disclosed in CN111098925B. However, these trailers suffer from long loading and unloading times when transporting goods that require separate components, as each component needs to be individually secured. Utility Model Content

[0004] To address the aforementioned issues, this application provides a box trailer with multiple storage spaces, facilitating the quick disassembly and placement of components.

[0005] The box trailer provided in this application adopts the following technical solution:

[0006] A box trailer includes a frame with a first cargo box and a second cargo box on the frame. The first and second cargo boxes are arranged front to back along the forward direction of the trailer. A bracket is fixed above the second cargo box. A first side door is hinged to both sides of the bracket. A second side door is hinged to the end of the bracket away from the first cargo box. The end of the bracket near the first cargo box is closed, and the upper end of the bracket is closed. Gas springs are installed on the first side door and the bracket, as well as on the second side door and the bracket. A partition is provided inside the second cargo box to divide it into a first chamber and a second chamber. A long drawer is slidably connected inside the first chamber. The long drawer is equipped with two parallel rails arranged vertically. Rollers corresponding to the rails are installed on the side walls of the first chamber.

[0007] Optionally, the upper surface of the second chamber has an opening, and an upper door panel is hinged to the opening. The upper door panel is connected to the second chamber by a gas spring. When the upper door panel is closed, the upper surface of the upper door panel is flush with the upper surface of the first chamber.

[0008] Optionally, two long drawers are provided.

[0009] Optionally, the upper surface of the second chamber is provided with two openings, and two openings are symmetrically provided on the upper door panel, with the adjacent ends of the upper door panel being hinged to the second chamber.

[0010] Optionally, the first cargo box has openings on both sides, and each opening is hinged with a door, with a gas spring connecting the door to the first cargo box.

[0011] Optionally, both the frame and the bracket are equipped with storage racks.

[0012] Optionally, a barrier is installed on the upper surface of the first cargo box.

[0013] Optionally, a first limiting member is fixed on the long drawer, and a second limiting member is fixed on the inner wall of the first chamber, with the first limiting member located on the inner side relative to the second limiting member.

[0014] In summary, this application includes at least one of the following beneficial technical effects: the box trailer has multiple storage spaces that can be used to store goods separately; the long drawer uses a double-track sliding mechanism for a stable structure; the first and second side doors, the upper door panel, and the box door are all connected by gas springs for easy opening.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a box trailer, mainly used for transporting agricultural machinery, including a frame 1. Two wheels 2 are mounted on each side of the rear end of the frame 1, for a total of four wheels 2. A guide wheel 3 is located at the front end of the frame 1. A first cargo box 4 and a second cargo box 5 are mounted on the frame 1, arranged front-to-back along the trailer's forward direction. The first cargo box 4 is located at the front end of the frame 1, and the second cargo box 5 is located at the rear end of the frame 1. A bracket 6 is fixed above the second cargo box 5. First side doors 7 are hinged to both sides of the bracket 6, and a second side door 8 is hinged to the end of the bracket 6 away from the first cargo box 4. The end of the bracket 6 near the first cargo box 4 is closed by a first side plate 9, and the upper end of the bracket 6 is closed by a first top plate 10. The bracket 6 and the first side plate 9 can be welded, bolted, or riveted together. The bracket 6 and the first top plate 10 can also be welded, bolted, or riveted together. A placement space is formed by the first side door 7, the second side door 8, the first side plate 9, the first top plate 10, and the upper surface of the second cargo box 5. Goods are stored and retrieved by opening the first side door 7 and the second side door 8. The upper ends of both the first side door 7 and the second side door 8 are hinged to the bracket 6, and the lower ends are equipped with locks 11. The locks 11 can be any type of lock, as long as they can lock when the first side door 7 and the second side door 8 are closed. Since the locks 11 are conventional technology, they will not be described in detail.

[0022] Gas springs are installed on both the first side door 7 and its support 6, and on both the second side door 8 and its support 6. Specifically, the gas spring on the first side door 7 and its support 6 is defined as the first gas spring 12. One end of the first gas spring 12 is hinged to the support 6, and the other end is hinged to the middle of the first side door 7. This middle position is not necessarily exactly in the center, but rather relatively close to the middle. Similarly, the gas spring on the second side door 8 and its support 6 is defined as the second gas spring. One end of the second gas spring is hinged to the support 6, and the other end is hinged to the middle of the second side door 8.

[0023] The second cargo box 5 is divided into a first chamber and a second chamber by a partition 13. A long drawer 14 is slidably connected to the first chamber; actually, two long drawers 14 are provided. Therefore, the first chamber is divided into two smaller chambers by the first intermediate plate 26, and each smaller chamber contains one long drawer 14. Two parallel rails 15 are fixedly installed on both sides of each long drawer 14, typically bolted to the side wall of the long drawer 14. Rollers 16 corresponding to the rails 15 are installed on the side wall of the first chamber. These rollers 16 are axle-driven rollers, with the axle fixed to the side wall of the first chamber, allowing the rollers 16 to rotate relative to the axle. The lower surface of the rollers 16 contacts the rails 15. A first limiting member 17 is fixed to the long drawer 14, and a second limiting member 18 is fixed to the inner wall of the first chamber, with the first limiting member 17 located inside the second limiting member 18. In actual installation, the long drawer 14 is slid in first, and then the second limiting member 18 is installed. The second limiting member 18 is generally a limiting bolt, and the first limiting member 17 can be a limiting block welded to the side wall of the long drawer 14. Figure 2 In order to facilitate the display of the second limiting member 18, the long drawer 14 is moved outward beyond the maximum stroke. In the figure, the first limiting member 17 is on the outside relative to the second limiting member 18, but it should actually be on the inside.

[0024] The upper surface of the second chamber has an opening, and an upper door panel 19 is hinged to the opening. The upper door panel 19 is connected to the second chamber via a gas spring, defined as a third gas spring 20. One end of the third gas spring 20 is hinged to the upper door panel 19, and the other end is hinged to the inner wall of the second chamber. When the upper door panel 19 is closed, its upper surface is flush with the upper surface of the first chamber. The second chamber is actually divided into two smaller chambers by a second intermediate plate 27. Correspondingly, the upper surface of the second chamber has two openings, and the upper door panel 19 has two openings symmetrically arranged. The adjacent ends of the upper door panels 19 are hinged to the second intermediate plate of the second chamber.

[0025] The first cargo box 4 has openings on both sides, and each opening is hinged with a door 21. A gas spring is connected between the door 21 and the first cargo box 4. Here, the gas spring is defined as the fourth gas spring 22. One end of the fourth gas spring 22 is hinged to the door 21, and the other end is hinged to the first cargo box 4.

[0026] Locks 11 are also installed on the long drawer 14, the upper door panel 19 and the box door 21. The locks 11 can be the same as the locks 11 on the first side door 7 and the second side door 8.

[0027] Both the frame 1 and the support 6 are equipped with shelves 23. The shelf 23 on the frame 1 has a fixed support rod 24 at its bottom, so that the shelf 23 on the frame 1 and the shelf 23 on the first top plate 10 above the support 6 are at the same horizontal height. Some materials such as steel pipes can be placed there, and then tied with ropes or cable ties.

[0028] A barrier 25 is installed on the upper surface of the first cargo box 4, and the area formed by the barrier 25 can also be used for placing goods.
