Description
Technical Field
[0001] This utility model belongs to the field of special vehicles and relates to a high-load adjustable cargo basket for special vehicles. Background Technology
[0002] For special vehicles, especially rescue support vehicles, a backpack is usually installed at the rear of the vehicle, turret, or outside the cabin to expand the cargo space. This backpack can hold maintenance equipment, tools, bags, tarpaulins, and other items suitable for off-vehicle operations. This is to meet the purposes of expanding carrying capacity, rapid support, and mobile operations, while also providing protection and specifically reducing the damage from certain types of ammunition.
[0003] Most existing vehicle cargo baskets, such as Figure 1 As shown, the overall frame structure is fixed to the outer surface of the vehicle body, with evenly spaced compartments for placing items.
[0004] Traditional vehicle cargo baskets have two main drawbacks. First, their inherent suspended and fixed structure, with the fixing interfaces located on the side of the vehicle body, limits their overall width. If they are too wide, the load-bearing lever arm becomes longer, increasing the torque and making the interfaces prone to deformation, which can prevent them from detaching and compromise their load-bearing capacity. Second, the internal storage space of the basket is relatively fixed and cannot be adjusted. If the size of the load changes, it cannot be placed or fixed, requiring the entire cargo basket to be redesigned and replaced, resulting in low carrying efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a high-load-bearing adjustable cargo basket for special vehicles. The structure includes a fixed beam, an adjusting beam, a telescopic plate, a bottom support system, a fixed base, connecting pins, hinges, and fasteners. The fixed beam and adjusting beam are assembled through welding, bolting, or other methods to form the main frame structure of the basket. The telescopic plate is bolted to the adjusting beam for adjustable size, meeting the load-bearing requirements of equipment of different sizes. The entire basket frame is fixed to the vehicle body via hinges, fixed bases, and connecting pins, and two support rods are provided at the bottom to strengthen load support. This device has a strong overall load-bearing capacity, eliminating the inherent defects of insufficient rigidity and easy deformation; the internal storage space is adjustable in size to accommodate equipment of different sizes according to field needs, improving storage efficiency; the entire basket can be scaled proportionally to adapt to the design and use of different types of special vehicles.
[0006] The solution adopted in this utility model is as follows:
[0007] A high-load-bearing adjustable cargo basket for special vehicles includes a fixed beam, an adjusting beam 1, an adjusting beam 2, an adjusting beam 3, an adjusting beam 3, an adjusting beam 4, an adjusting beam 4, an adjusting beam 5, an adjusting beam 6, an adjusting beam 6, an adjusting beam 7, a telescopic plate, a bottom support rod system, a fixed seat, a connecting pin, a hinge, a through pin, a tray, and a cover plate.
[0008] The fixed beam and the adjusting beams 1, 2, 3, 3, 4, 5, 5, 6, 6, 7, and 8 form a rectangular frame structure for carrying the basket.
[0009] Adjusting beam 1 (2) is L-shaped. Adjusting beam 6 (7) is a vertical beam, with its upper end welded to the horizontal beam of adjusting beam 1 (2). It is located in the middle of the storage space of the cuboid frame structure, dividing the carrying basket of the cuboid frame structure into left and right sections. Adjusting beam 2 (3) and adjusting beam 3 (4) are horizontal beams located at the bottom of the frame structure. The two ends of adjusting beam 2 (3) and adjusting beam 3 (4) are welded to the left and right fixed beams, and the middle of them is welded to the bottom short beam, forming the bottom support of the cuboid frame structure. Adjusting beam 2 (3) and adjusting beam 3 (4) have sliding grooves and fixing holes on their upper parts. Adjusting beam 4 (5) and adjusting beam 5 (6) are two vertical beams that, together with the fixed beams, form the left side frame. Adjusting beam 4 (5) and adjusting beam 5 (6) are both equipped with adjustment holes. Adjusting beam 7 (8) serves as the upper horizontal beam on the front of the cuboid frame structure, and it has sliding grooves and fixing holes. The lower ends of adjusting beam 1 (2) and adjusting beam 6 (7) can slide along adjusting beam 2 (3) and adjusting beam 3 (4) respectively. The fixed beam slides along adjusting beam 7 (8) and is bolted to a fixed position.
[0010] There are three hinges 13, located on the left side of the rectangular frame structure carrying basket, one at the top and one at the bottom, and one in the upper 1 / 4 of the middle. One end of the hinge 13 is welded to the vehicle body, and the other end is welded to the adjusting beam 4 5. The rectangular frame structure carrying basket can be rotated and opened along the hinge axis. There are two fixing seats 11, which are welded to the vehicle body at the far end away from the hinges. There are also two connecting pins 12, which are welded to the fixing beam and adjusting beam 2 3 of the rectangular frame structure carrying basket, respectively, and their positions correspond to the fixing seats 11. After the fixing seats 11 and connecting pins 12 are connected, they are fixed with pins 14. There are two bottom support rods 10, which are evenly distributed at the bottom of the basket. One end is fixed to the vehicle body with a pin, and the other end is fixed to the basket fixing beam with a pin.
[0011] The telescopic plate 9 is laid flat and installed in the middle of one of the storage areas of the rectangular frame structure carrying basket, which further divides the storage area in the vertical direction and increases the storage capacity.
[0012] Furthermore, both ends of the adjusting beam 12 and the lower end of the adjusting beam 67 are semi-circular insert plate structures. The adjusting beam 12 and the adjusting beam 67 as a whole can move in the sliding grooves of adjusting beam 23, adjusting beam 34, and adjusting beam 78. When the moving position is appropriate, bolts are used to pass through the fixing holes to fix the insert plates to the sliding grooves of adjusting beam 23, adjusting beam 34, and adjusting beam 78.
[0013] Furthermore, the telescopic plate 9 has a drawer-like sliding structure, including an upper fixed plate and a lower movable plate. The upper fixed plate and the lower movable plate adopt an overlapping slot combination, and the length is adjustable when pulled out.
[0014] Furthermore, the lower movable plate of the telescopic plate 9 can move along with the overall movement of the adjusting beam 1 2 and the adjusting beam 6 7 to adjust the length; the telescopic plate 9 is fixed by being bolted to four L-shaped brackets at the bottom.
[0015] Furthermore, L-shaped support plate 4 18 is located at the intersection of adjusting beam 4 5 and telescopic plate 9. Both the upper and lower plates of the L-shaped support plate have mounting holes, which are then fastened to the fixed plates of adjusting beam 4 5 and telescopic plate 9, ensuring that the fixed plates remain stationary when telescopic plate 9 is extended or retracted. L-shaped support plate 1 15 is located at the intersection of adjusting beam 5 6 and telescopic plate 9. The lower plate of the L-shaped support plate has mounting holes, which are then fastened to adjusting beam 5 6. It only contacts and supports the telescopic plate 9 without being fixed. L-shaped support plate 3 17 is located at the intersection of adjusting beam 1 2 and telescopic plate 9. The lower plate of the L-shaped support plate has mounting holes, which are then fastened to adjusting beam 1 2. It only contacts and supports the telescopic plate 9 without being fixed. L-shaped support plate 2 16 is located at the intersection of adjusting beam 6 7 and telescopic plate 9. Both the upper and lower plates of the L-shaped support plate have mounting holes, which are then fastened to the movable plates of adjusting beam 6 7 and telescopic plate 9, ensuring that the movable plate of telescopic plate 9 extends or retracts accordingly when adjusting beam 6 7 moves as a whole.
[0016] Furthermore, the adjusting beams 1-2, 4-5, 5-6, and 6-7 all have evenly distributed positioning holes on the side facing the telescopic plate. By adjusting the installation position of the L-shaped support plate 1-15, L-shaped support plate 2-16, L-shaped support plate 3-17, and L-shaped support plate 4-18, the height of the telescopic plate 9 can be adjusted, thereby improving the storage efficiency.
[0017] Furthermore, adjustment beams 2 and 3 have notches near the hinge end, facing the vehicle body, to facilitate the installation and insertion of adjustment beams 1 and 6 into the grooves of adjustment beams 2 and 3.
[0018] Furthermore, the fixing holes on the second adjusting beam 3 are evenly distributed at 18mm center intervals on the side facing the vehicle body.
[0019] Furthermore, the adjustment beam has four sliding grooves on its top, with adjacent fixing holes spaced 18mm apart and evenly distributed on the side facing away from the car body.
[0020] Furthermore, the adjustment beam 78 slide groove is located on the side facing the vehicle body, with adjacent fixing holes spaced 18mm apart and evenly distributed on the top.
[0021] The beneficial effects of this utility model are:
[0022] The advantages of this utility model are as follows: First, the addition of a support rod system at the bottom eliminates the problems of long suspension and fixing lever arm, easy deformation, and weak load-bearing capacity of traditional backpacks, thus enhancing load-bearing capacity; second, the size of the internal storage space partitions is adjustable, accommodating equipment of different sizes according to field storage needs, improving storage efficiency; third, the entire backpack can be flipped, improving the operability and convenience of loading and unloading, while also increasing the space utilization rate of the backpack. This high-load-bearing adjustable backpack for special vehicles solves the problems of the traditional backpack's single and unchanging storage space, weak load-bearing capacity, and easy deformation, providing ideas and support for the expanded design of various high-efficiency storage backpacks.
