Description

Technical Field

[0001] This utility model relates to the field of tire rack technology, and in particular to a folding combination rack suitable for tires of various specifications. Background Technology

[0002] Tire racks, as professional warehousing equipment, are specifically designed for the storage, display, and inventory management of tires. Their core structure is based on a multi-layered beam, column, or frame system, enabling the orderly layered storage of tires of different specifications, such as passenger car tires, truck tires, and engineering tires. Through an adjustable layer spacing design, this equipment balances load-bearing requirements with space utilization, facilitating forklift access as well as manual counting and selection. Widely used in 4S store showrooms, repair shop storage areas, and tire logistics centers, it effectively saves space, protects tires from compression and deformation, and improves storage and retrieval efficiency, making it an important tool for standardized inventory management in the tire industry.

[0003] Folding combination racks suitable for various tire sizes feature a flexible and adjustable design, accommodating a wide range of tire specifications. They are foldable for storage, significantly saving space and facilitating convenient storage and transportation. Whether for large truck tires or small car tires, they can be properly accommodated. Existing folding combination racks use multiple sets of parallel horizontal support rods on each layer, with the spacing between the support rods adjustable via bolts. However, this adjustment is inefficient and relies on manual operation, requiring manual adjustment of the support rod spacing one by one or in groups. While some existing technologies utilize cylinders or hydraulic cylinders to push the support rods along slide rails, controlling the movement speed and stroke of the support rods via air or hydraulic valves to accommodate different tire sizes, these valves rely on piston seals to isolate the air chamber. Long-term reciprocating motion causes the seals to wear down and lose elasticity, leading to a decrease in cylinder thrust or even failure to push the rack. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide a folding combination rack suitable for various tire specifications. This aims to improve the existing technology where the movement speed and stroke of the support rod are controlled and adjusted by air valves or hydraulic valves to adapt to tires of different sizes. However, the air valves or hydraulic valves rely on piston seals to isolate the air chamber. Long-term reciprocating motion will cause the seals to wear and lose elasticity, resulting in a decrease in cylinder thrust or even failure to push.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A folding combination shelf suitable for various tire sizes includes multiple side rails, with a placement mechanism installed on the outer bottom of each side rail for storing tires of different sizes. The placement mechanism includes a base, which is installed on the outer bottom of the side guardrail. Multiple crossbars are provided on the top of the base. Pull ropes are installed on the front and back sides of the outer top of the base. Self-locking buckles are fixedly connected to the left and right ends of the outer walls of the multiple pull ropes. Multiple limiting plates are fixedly connected at equal intervals on the top left and right sides of the outer wall of the base, and the two ends of the crossbar are respectively embedded between two adjacent limiting plates.

[0006] Furthermore, each of the side rails is equipped with an adjustment mechanism at its top, which is used to adjust the height of the side rails.

[0007] Furthermore, the adjustment mechanism includes multiple telescopic frames, which are installed at the top of the side guardrail. Racks are fixedly connected to the bottom front and rear sides of the outer wall of the telescopic frame. Gears are installed on the outer walls of the multiple racks, and the outer walls of the gears mesh with the outer walls of the racks. A rotating shaft is fixedly connected to the middle of the multiple gears, and a knob is fixedly connected to one end of the outer wall of the multiple rotating shafts away from each other.

[0008] Furthermore, ratchet wheels are fixedly connected to adjacent ends of the outer walls of the plurality of rotating shafts, the plurality of ratchet wheels are installed in the middle of the side guardrail, pawls are installed on the outer sides of the plurality of ratchet wheels, and a limit shaft is rotatably connected inside the pawls, the outer wall of the limit shaft being fixedly connected to the outer wall of the side guardrail.

[0009] Furthermore, hollow support columns are fixedly connected to the four corners of the base, and the middle part of the hollow support columns is slidably connected to the bottom of the outer wall of the side guardrail.

[0010] Furthermore, a forklift positioning sleeve is fixedly connected to the bottom of the base.

[0011] Furthermore, cross braces are installed on the front and rear sides of the outer top of the base, and the cross braces are installed on the outer bottom of the pull cord.

[0012] Furthermore, multiple fixing sleeves are installed on the outer top of the base, and the outer walls of the multiple fixing sleeves are fixedly connected to the outer wall of the side guardrail, while the interior of the fixing sleeves is slidably connected to the outer wall of the cross brace.

[0013] Furthermore, each of the self-locking buckles is internally slidably connected to a buckle fixing bracket, and each of the buckle fixing brackets is fixedly connected to the side guardrail.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) In this utility model, hollow legs are installed at the bottom of the side guardrail. The side guardrail is fixed by two short shafts. The shelf can be folded by removing the upper short shaft. The four hollow legs are connected by the base. Multiple forklift positioning sleeves are welded to the bottom of the base to facilitate the movement of the shelf position by forklifts. When it is necessary to place tires of different widths, it is only necessary to place the two crossbars inside the limiting plate at a suitable distance according to the tire width to achieve the storage of tires of different widths.

[0015] (2) In this utility model, multiple racks are installed at the bottom of the telescopic frame. They can rotate synchronously by meshing with the gears.

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a folding combination rack suitable for tires of various specifications, including multiple side rails 1. A placement mechanism 2 is installed on the outer bottom of each side rail 1 for storing tires of different specifications. An adjustment mechanism 3 is installed at the top of each side rail 1 for adjusting the height of the side rail 1. The placement mechanism 2 includes a base 201 installed on the outer bottom of each side rail 1. Hollow legs 204 are fixedly connected to the four corners of the base 201, with the middle of each hollow leg 204 slidably connected to the bottom of the outer wall of the side rail 1. Forklift positioning sleeves 202 are fixedly connected to the front, rear, left, and right sides of the bottom of the outer wall of the base 201. Multiple crossbars 203 are provided on the top outer side. Pull ropes 208 are installed on the front and rear sides of the top outer side of the base 201. Self-locking buckles 207 are fixedly connected to the left and right ends of the outer walls of the multiple pull ropes 208. Horizontal supports 206 are installed on the front and rear sides of the top outer side of the base 201. The horizontal supports 206 are installed at the bottom outer side of the pull ropes 208. Multiple limiting plates 210 are fixedly connected at equal intervals on the left and right sides of the top outer wall of the base 201. The two ends of the multiple crossbars 203 are respectively installed between two adjacent limiting plates 210. Multiple fixing sleeves 205 are installed on the top outer side of the base 201. The outer walls of the multiple fixing sleeves 205 are fixedly connected to the outer wall of the side guardrail 1. The inside of the fixing sleeves 205 is slidably connected to the outer wall of the horizontal supports 206.

[0020] Specifically, hollow support posts 204 are installed at the bottom of the side rail 1, which are fixed to the side rail 1 by two short shafts. Removing the upper short shafts allows the rack to be folded. The four hollow support posts 204 are interconnected via a base 201. Multiple forklift positioning sleeves 202 are welded to the bottom of the base 201 to facilitate forklift movement of the rack. A fixing sleeve 205 is installed above the base 201; this support sleeve can be used to place cross braces 206. When tires are stored on the rack, the cross braces 206 provide stable support. When the rack needs to be folded, the cross braces 206 can be removed for folding. A pull cord 208 is also installed at the top of the cross brace 206, with self-locking buckles 207 welded to both ends, connecting to the side rail 1 via buckle fixing brackets 209. This structure allows for forklift movement... The racks for storing tires play a protective role, preventing tires from falling off the racks due to bumps during movement. The hollow support column 204 has sufficient space inside, allowing the racks to be stacked to form multi-layer racks, further increasing the storage capacity of folding combination racks for tires of different sizes. When it is necessary to store tires of different widths, simply place the two crossbars 203 inside the appropriate distance from the limiting plate 210 according to the tire width size, and the tires of different widths can be stored. This solves the problem that when the speed and stroke of the support rod are adjusted by controlling the movement of the support rod to adapt to different tire sizes through air valves or hydraulic valves, the air chamber is isolated by the piston seal ring inside the air valve or hydraulic valve. Long-term reciprocating motion will cause the seal ring to wear and lose elasticity, which will result in a decrease in cylinder thrust or even failure to push.

[0021] Reference Figure 2 , Figure 3 and Figure 5 The adjustment mechanism 3 includes multiple telescopic frames 301, which are installed at the top of the side guardrail 1. The outer bottom of the telescopic frame 301 is fixedly connected to the front and rear sides of the bottom of the outer wall of the telescopic frame 301. The outer walls of the multiple racks 302 are equipped with gears 304, which mesh with the outer walls of the racks 302. The middle of the multiple gears 304 is fixedly connected to the rotating shaft 303. The outer walls of the multiple rotating shafts 303 are fixedly connected to the ends away from each other. The outer walls of the multiple rotating shafts 303 are fixedly connected to the adjacent ends of the outer walls of the multiple rotating shafts 303. The multiple ratchet wheels 306 are installed in the middle of the side guardrail 1. Specifically, multiple racks 302 are installed at the bottom of the telescopic frame 301. These racks 302 rotate synchronously by meshing with gears 304. When the knob 305 is turned, the power generated is transmitted to the gears 304 through the shaft 303. With the help of meshing, the racks 302 move vertically, thereby driving the telescopic frame 301 to move vertically as well, thus realizing the adjustment of the height of the side guardrail 1. A ratchet 306 is installed at the other end of the shaft 303. Through the limiting effect of its outer pawl 307, the telescopic frame 301 can maintain a fixed position without being affected by gravity, further improving the internal space utilization of the folding combination rack.

[0022] Reference Figure 1 , Figure 2 and Figure 3 Each ratchet 306 has a pawl 307 mounted on its outer side. The pawl 307 is rotatably connected to a limit shaft 308. The outer wall of the limit shaft 308 is fixedly connected to the outer wall of the side guardrail 1.

[0023] Specifically, pawls 307 are installed on the outer side of multiple ratchet wheels 306. Pawls 307 are rotatably connected to limit shafts 308. The outer wall of limit shafts 308 is fixedly connected to the outer wall of the side guardrail 1. This connection method allows pawls 307 to rotate flexibly around limit shafts 308, thereby better cooperating with ratchet wheels 306 to play a limiting role. This ensures that after adjusting the height of telescopic frame 301, its position can be stably maintained and will not change due to external forces, further enhancing the stability and reliability of adjustment mechanism 3.

[0024] Working principle: Hollow support columns 204 are installed at the bottom of the side railing 1. These columns are secured to the side railing 1 via two short shafts. Removing the upper short shafts allows the rack to be folded. The four hollow support columns 204 are connected by a base 201. Multiple forklift positioning sleeves 202 are welded to the bottom of the base 201, facilitating forklift movement of the rack. A fixing sleeve 205 installed above the base 201 can hold a cross brace 206, providing stable support when storing tires. This cross brace can be removed for folding. A pull cord 208 is installed at the top of the cross brace 206, with self-locking buckles 207 welded to both ends, connecting to the side railing 1 via a buckle fixing bracket 209. This allows for forklift movement of the tire storage rack. It provides protection during movement, preventing tires from falling off the shelf due to impacts. Because the hollow support column 204 has sufficient internal space, the shelves can be stacked to form multi-layer shelves, further increasing the storage capacity of folding combination shelves for tires of different sizes. When it is necessary to store tires of different widths, simply place the two crossbars 203 inside the limiting plate 210 at an appropriate distance according to the tire width. This solves the problem that the movement speed and stroke of the support rod are controlled and adjusted by air valves or hydraulic valves to adapt to different sizes of tires. The air valves or hydraulic valves rely on piston seals to isolate the air chamber. Long-term reciprocating motion will cause the seals to wear and lose elasticity, resulting in a decrease in cylinder thrust or even failure to push.

[0025] Multiple racks 302 are installed at the bottom of the telescopic frame 301. They can rotate synchronously by meshing with gears 304. When the knob 305 is turned, its power can be transmitted to the gears 304 through the rotating shaft 303. Through meshing, the racks 302 move vertically, thereby driving the telescopic frame 301 to move vertically, realizing the adjustment of the height of the side guardrail 1. A ratchet 306 is installed at the other end of the rotating shaft 303. Through the limiting effect of its outer pawl 307, the telescopic frame 301 can be kept in a fixed position without being affected by gravity, further improving the internal space utilization of the folding combination shelf.

[0026] A coal port's materials management department's bulk cargo warehouse has achieved three major breakthroughs in efficiency by applying new warehousing equipment: Improved space efficiency: Based on a modular folding architecture design, the equipment can be quickly converted for storage, increasing tire storage capacity by 60% and reducing shelf footprint by 40%.

[0027] Upgraded adaptability: Through an innovative lateral adjustment system, it can accurately match multiple tire sizes and specifications, enabling intelligent storage in layers and zones, significantly improving the efficiency of manual counting and the accuracy of picking.

[0028] Enhanced operational safety: The adoption of dynamic balance load-bearing technology improves the efficiency of forklift operation and retrieval, reduces the risk of equipment tipping over to zero, and comprehensively ensures the safety of high-density operations.

[0029] This equipment breaks through the limitations of traditional warehousing models, constructing a three-dimensional storage system within a limited space, which significantly improves inventory turnover and reduces economic losses caused by operational errors on average each year, setting a benchmark for the transformation of port warehousing management of such materials.
