Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically a folding vehicle-mounted shelving. Background Technology

[0002] Vehicle-mounted racking is a racking system specifically designed for vehicles. It is installed inside the vehicle for storing goods during transportation. The design of vehicle-mounted racking typically needs to be flexible and foldable to facilitate loading and unloading of goods and save space.

[0003] In modern logistics and transportation, the use of truck-mounted racks is becoming increasingly common. They not only improve transportation efficiency but also increase the safety of goods. However, truck-mounted racks face a significant challenge during use: the jolting caused by vehicle movement. Since most truck-mounted racks are installed inside the truck bed, and many are foldable, their legs are not fixed to the bed. Therefore, jolting is unavoidable during vehicle movement, especially when traversing uneven roads. This jolting is transmitted to the racks inside the truck bed, causing them to shift, and in severe cases, even causing goods to fall off the racks, resulting in losses.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing shelving system. Utility Model Content

[0005] This utility model addresses the problem that existing technical solutions are too simplistic by providing a folding vehicle-mounted rack that is significantly different from existing technologies, thus solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a folding vehicle-mounted shelf, including an H-shaped support frame, a folding structure connecting the two sides of the H-shaped support frame, and a load-bearing structure for carrying goods installed between the H-shaped support frames, with a stabilizing structure installed at the bottom of each H-shaped support frame to prevent shaking and movement.

[0007] Preferably, the folding structure includes a first inclined frame, a second inclined frame, and a sliding sleeve. The first and second inclined frames are arranged in an "X" shape, intersecting on the outside of the H-shaped support frame, and are rotatably connected at their intersection. One end of the first inclined frame is rotatably connected to the outside of the H-shaped support frame, and the other end of the first inclined frame is rotatably connected to the sliding sleeve, which is slidably connected to the outer wall of the H-shaped support frame. One end of the second inclined frame is rotatably connected to the outside of the H-shaped support frame, and the other end of the second inclined frame is rotatably connected to the sliding sleeve.

[0008] Preferably, the load-bearing structure includes a connecting shaft, a connecting sleeve, a load-bearing frame, and a load-bearing plate. Each H-shaped support frame is rotatably connected to a connecting shaft, and at least two connecting sleeves are connected to the outer wall of the connecting shaft. Each connecting sleeve is connected to a load-bearing frame. The end of each load-bearing frame is hung on the outer wall of the connecting shaft on another H-shaped support frame, and a load-bearing plate for carrying goods is installed on the outer wall of each load-bearing frame in the area between the two H-shaped support frames.

[0009] Preferably, the support frame is arranged in a zigzag shape, and the end of the support frame is configured as a hook-like structure for mounting on the outer wall of another connecting shaft.

[0010] Preferably, the stabilizing structure includes a vacuum section and a locking section. The vacuum section includes a housing, a piston block, a connecting rod, a mounting groove, and a return spring. Each H-shaped support frame has a housing connected to its lower end. Each housing has a piston block slidably connected to it, and each piston block has a connecting rod connected to it. Each connecting rod is located in a mounting groove, which is formed within the H-shaped support frame. A return spring is connected between each mounting groove and the connecting rod.

[0011] Preferably, the locking part includes a groove, a pressure spring, a rod, and a slot. Each H-shaped support frame has a groove, and each groove is connected to a pressure spring. Each pressure spring has a rod connected to its end. One end of each rod penetrates the outer wall of the H-shaped support frame, and the other end of each rod is located in the slot. The slot is located on the outer wall of the connecting rod.

[0012] Preferably, the bottom opening area of ​​the box body is provided with a rubber layer to improve sealing, and the insertion rod is provided with an arc-shaped structure on the lower side of the inner end of the slot.

[0013] Compared with existing technologies, the advantages of this utility model are: This folding vehicle-mounted rack, through its folding structure, allows the H-shaped support frame to be compactly folded and stored, maximizing the use of space within the vehicle. When not carrying goods, this design significantly reduces space occupation, while when carrying goods, the H-shaped support frame can be quickly and easily assembled, ensuring high operational efficiency and convenience. Furthermore, this load-bearing structure design also considers the need for rapid loading and unloading, making the entire process smoother and greatly improving transportation efficiency.

[0014] The robust structure utilizes a negative pressure space created between the vacuum-sealed housing and the bottom of the truck bed, with the H-shaped support frame firmly secured to the interior through the housing's suction. This unique fixing method ensures the racking remains stable even during vehicle movement, effectively preventing rack displacement and cargo spillage. This stabilizing effect not only enhances the safety of cargo transportation but also reduces potential losses due to scattered goods. Through this structural design, the stability and reliability of the truck-mounted racking are significantly improved, providing a more solid guarantee for long-distance transportation.

[0025] The load-bearing structure 3 includes a connecting shaft 301, a connecting sleeve 302, a load-bearing frame 303, and a load-bearing plate 304. Each H-shaped support frame 1 is rotatably connected to a connecting shaft 301, and the outer wall of the connecting shaft 301 is connected to at least two connecting sleeves 302. Each connecting sleeve 302 is connected to a load-bearing frame 303. The end of each load-bearing frame 303 is hung on the outer wall of the connecting shaft 301 on another H-shaped support frame 1. Each load-bearing frame 303 is equipped with a load-bearing plate 304 for carrying goods in the area between the two H-shaped support frames 1.

[0026] The support frame 303 is arranged in a zigzag shape, and the end of the support frame 303 is configured as a hook-like structure for mounting on the outer wall of another connecting shaft 301.

[0027] The stabilizing structure 4 includes a vacuum section and a locking section. The vacuum section includes a housing 401, a piston block 402, a connecting rod 403, a mounting groove 404, and a return spring 405. Each H-shaped support frame 1 has a housing 401 connected to its lower end. Each housing 401 has a piston block 402 slidably connected inside it. Each piston block 402 has a connecting rod 403 connected to it. Each connecting rod 403 is located in the mounting groove 404, which is opened in the H-shaped support frame 1. Each mounting groove 404 and the connecting rod 403 are connected to a return spring 405.

[0028] The locking part includes a groove 406, a pressure spring 407, a rod 408, and a slot 409. Each H-shaped support frame 1 has a groove 406, and each groove 406 is connected to a pressure spring 407. Each pressure spring 407 has a rod 408 connected to its end. One end of each rod 408 passes through the outer wall of the H-shaped support frame 1, and the other end of each rod 408 is located in the slot 409.

[0030] Working principle: According to Figure 1 As shown, firstly, the H-shaped support frame 1 is pulled to widen its spacing. At the same time, the first inclined frame 201 and the second inclined frame 202 rotate around the intersection point to open and limit the H-shaped support frame 1. Then, the connecting sleeve 302 is moved to rotate on the connecting shaft 301, so that the end hook of the bearing frame 303 on the connecting sleeve 302 is attached to the connecting shaft 301 on another H-shaped support frame 1. The goods are supported by the bearing plate 304 on the bearing frame 303.

[0031] Then, pull the connecting rod 403 upward to move it in the mounting groove 404, which will drive the piston block 402 to move upward in the box 401, generating negative pressure. With the assistance of the rubber layer at the bottom of the box 401, the box 401 is firmly fixed to the bottom of the carriage, thereby achieving the limiting and fixing of the H-type support frame 1.

[0032] Meanwhile, as the connecting rod 403 moves upward within the mounting groove 404 and contacts the arc-shaped end of the insert rod 408, it compresses the insert rod 408 into the groove 406, and the pressure spring 407 is compressed. When the connecting rod 403 continues to move upward and its slot 409 aligns with the insert rod 408, the pressure spring 407 pushes the insert rod 408 and the slot 409 to engage, thus limiting and locking the connecting rod 403. This is the working principle of the folding vehicle-mounted rack.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
