Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, in particular to an underbody guard plate material rack. Background Art

[0002] Vehicles, especially construction vehicles, often have underbody guards installed to protect the engine, transmission, transfer case, and other components mounted on the vehicle frame. While in motion, especially during operation, a vehicle may encounter rocks, wood piles, or other protruding objects, causing debris to bounce and strike the underbody. Underbody guards prevent damage to the engine and other components from these protruding objects and prevent mud and sand from entering the equipment mounted on the vehicle frame, thereby extending its service life. Underbody guards also reduce wind resistance and wind noise.

[0003] At present, the main method of transporting bottom guard plates includes the use of special racks. The rack design can often only place parts in a single layer, resulting in low space utilization. During transportation, the bottom guard plates may shake due to vehicle bumps and other reasons, causing damage to parts. The complex rack structure may increase loading and unloading time and affect the efficiency of the production line. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4In this embodiment, a bottom guard plate material rack includes a frame 1 and two relatively distributed baffles 2 fixed on the frame 1, and four trapezoidally arranged opposite concave plates 3 are fixed thereto. The left and right side walls of the concave plates 3 are both provided with arc holes 6 arranged at equal distances from top to bottom, and a bottom hole 14 is provided below the arc hole 6 at the bottom. A rear rod 7 is fixed on the inner side of the concave plate 3 with a number matching the arc holes 6 and the bottom hole 14. The rear rod 7 is opposite to the center of the arc hole 6, so it is on the same center line and moves downward in sequence. Arranged and distributed until it is opposite to the bottom hole 14, a front rod 10 is slidably connected between the two opposite arc-shaped holes 6, and a seesaw 13 is movably connected between the front rod 10 and the rear rod 7. The outer side of the rear rod 7 is sleeved with a torsion spring 9 fixed to the inner wall of the concave plate 3 and the outer side of the front rod 10. Multiple front rods 10 are connected in series through a connecting plate 12, and the connecting plate 12 is rotatably connected to the front rod 10. A waist hole is opened at the connection between the connecting plate 12 and the lower front rod 10, and multiple connecting plates 12 are distributed on the left and right sides of the seesaw 13 from top to bottom.

[0019] In the above structure, when it is in a natural state, under the action of the torsion spring, the front rod is driven to move to the upper limit position of the arc hole, so that the front rod can drive the seesaw to return to the concave plate. Because the curvature of the bottom hole is smaller than that of the arc hole, the bottom seesaw will be tilted out at a certain angle, which is convenient for placing products. When the product is placed on the four seesaws, the seesaw is pressed down to a horizontal state, and the seesaw is limited by the bottom hole and the rear rod, so that the seesaw supports the product. When the bottom seesaw is flattened, the bottom front rod moves in the waist hole, and then pulls the connecting plate down again through the front rod, so that the upper layer The front rod is pulled down synchronously, and with the cooperation of the waist hole, the upper layer of seesaw can be opened to a certain angle, which is also convenient for placing the second layer of products. Then, by analogy, when placing the product, the upper layer can be automatically opened to provide convenience, while realizing stacking products to improve the utilization rate of the frame, and when the products are removed from top to bottom, under the action of the torsion spring, the front rod can be driven to move up, and at the same time, the seesaw is driven to retract to a certain angle, and then the products are removed from top to bottom. Therefore, the seesaw will be retracted to a certain angle into the guide concave plate, and the bottom seesaw will always maintain a certain angle when it is retracted, which is convenient for placing products.

[0020] At the same time, both sides of the section of the seesaw 13 away from the opening of the concave plate 3 are formed with convex edges, and the front rod 10 and the rear rod 7 are both inserted into the convex edges. In addition, a notch is formed on the side of the seesaw 13 away from the opening of the concave plate 3, opposite the torsion spring 9. When the seesaw 13 rotates in an arc, the contact between the rear side surface of the seesaw and the rear rod can act as a stop, and the notch can also prevent the seesaw from squeezing and damaging the torsion spring when it is flat.

[0021] Two sleeves 8 are fixed to the outside of the rear rod 7, located on either side of the rear end of the seesaw 13. Two stoppers 11 are fixed to the outside of the front rod 10, located on either side of the rear end of the seesaw 13. A gap equal to the thickness of the connecting plate 12 is left between the stoppers 11 and the seesaw 13, and the connecting plate 12 is held in position within the gap. The sleeves limit the seesaw's position, preventing it from moving left or right. The gap between the stoppers and the seesaw, which matches the connecting plate, acts as a position limiter.

[0022] In addition, side plates 5 covering the arc-shaped hole 6 and the bottom hole 14 are fixed on both sides of the concave plate 3. The side plates cover the arc-shaped hole and the bottom hole, thereby preventing the front rod from moving out of the arc-shaped hole when the arc-shaped hole slides, thereby limiting the front rod.

[0023] Furthermore, a side guard 4 is fixed to the side of the side panel 5 near the baffle 2. Anti-collision pads are fixed to the baffle surfaces of both the side guard 4 and the baffle 2. The baffle surface of the side guard 4 protrudes outward and is not on the same level as the opening of the concave plate 3. The baffle and side guards limit the position of the product, effectively preventing the product from shaking during transportation and colliding with the frame and concave plate, causing damage.

[0024] In addition, the four columns of the frame 1 are fixed with trapezoidal rods at the bottom and sockets adapted to the rods at the top. The combination of the rods and the sockets allows the frames to be placed together, thereby reducing the site occupancy rate and allowing them to be stacked and transplanted to improve efficiency.

[0025] The working principle of the above embodiment is:

[0026] By placing the products on the four seesaws at the bottom for support, when the four seesaws are flattened, the seesaw will be supported in the bottom hole by the bottom front rod, and the seesaw will also be supported by the rear rod contact. During the opening process, the front rod will move a certain distance in the waist hole of the connecting plate, and then pull the connecting plate down, while driving the front rod of the upper layer to move in the arc hole, and pull down one end a distance, so that the upper seesaw opens at a certain angle, which is convenient for placing the next group of products, and then places the products in this way, so there is no need to open the seesaw in turn, so it can effectively improve convenience, and also realize the stacking of products, which improves the utilization rate of the frame space. Therefore, large-scale transportation can improve the production efficiency of the production line, and then limit the products by baffles and side guards to prevent damage caused by collision during transportation.

[0027] Then, when the products are unloaded from top to bottom in sequence, the torsion spring can drive the front rod to move upward, and then, in conjunction with the linkage of the connecting plate and the waist hole, the next layer can be retracted to a certain angle, and the upper layer is completed and restored to the concave plate, and so on, until the top passes through the limit of the bottom hole, so that the bottom seesaw can always remain open at a certain angle.
