Description

Technical Field

[0001] This utility model relates to the field of tire storage and transportation equipment technology, specifically to a foldable tire rack for storing large finished tires such as semi-steel radial tires. Background Technology

[0002] Efficient and safe storage of finished tires is a crucial aspect of tire manufacturing plants, transit warehouses, and sales outlets. Currently, there are two main storage methods: one is to use fixed steel structure racks, and the other is to stack tires directly on the ground.

[0003] While fixed shelving allows for vertical stacking, its rigid structure prevents it from being folded. When unused, the shelving itself occupies a significant amount of storage space, resulting in wasted space resources. Furthermore, its installation typically requires tools, making movement difficult and limiting flexibility. Existing storage racks, which are essentially rigid, non-removable, and non-foldable structures, still suffer from inherent drawbacks such as high storage and transportation costs when unloaded and insufficient flexibility.

[0004] Meanwhile, ground stacking only utilizes space horizontally, resulting in extremely low space utilization. Furthermore, tires are easily contaminated due to direct contact with the ground, and unstable stacking can easily cause tires to tip over or suffer permanent deformation. Handling and organizing require a large amount of manpower, leading to high operating costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a foldable tire rack with a novel structure, simple operation, stable stacking, and foldable storage. The tire rack includes:

[0006] A support frame for holding finished tires, the support frame being composed of multiple support tubes and having open front and rear sides;

[0007] The left and right baffles are foldably mounted on the support frame. The left and right baffles have a folded state and an unfolded state. When they are in the folded state, they are parallel to the support frame and close together. When they are in the unfolded state, they are vertically erected on the left and right sides of the support frame.

[0008] A connecting assembly includes an upper connector and a lower connector; the upper connector is disposed at the top of the left and right baffle frames, and the lower connector is disposed at the bottom of the support frame; wherein, the lower connector of one of the tire holders can be connected to the upper connector of another tire holder to realize the stacking of multiple tire holders.

[0009] In some embodiments, the supporting frame, left baffle, and right baffle are all constructed by welding together hollow metal tubes.

[0010] In some embodiments, the left and right retaining frames are foldably connected to the support frame via hinges or quick-release pins.

[0011] In some embodiments, pads are provided at the four bottom corners of the support frame, and the lower connector is a positioning protrusion fixedly disposed on the pad.

[0012] In some embodiments, the upper connector is a positioning protrusion disposed on the top of the left and right retaining frames, its position corresponding to the slot, so that the positioning protrusion can be inserted into the slot when stacked vertically. In some embodiments, the longitudinal section of the positioning protrusion is a trapezoidal shape with a smaller upper section and a larger lower section, and the insertion slot has a trapezoidal inner cavity that is interference-fitted with it.

[0013] In some embodiments, the support frame includes multiple parallel support tubes, and the gap between two adjacent support tubes is smaller than the ground width of the tire to be stored.

[0014] In some embodiments, the left and / or right retaining frames are provided with label plates for attaching tire information labels.

[0015] In some embodiments, at least one carrying handle is provided on the bottom support tube of the carrier frame.

[0016] In some embodiments, the support frame is provided with a flange for stopping the tire from rolling.

[0017] Compared to existing technologies, this invention features a foldable side frame design, allowing the rack to be folded into a near-flat shape when unloaded, saving approximately 60%-70% of storage and transportation space compared to traditional fixed shelving, significantly reducing costs. Furthermore, the connecting component design directly transfers stacking stress points through the feet and the top of the side frame, resulting in a scientifically sound structure. The trapezoidal positioning protrusions and interlocking slots ensure stacking stability and safety, preventing the risk of tipping over. The rack provided by this invention requires no tools during folding and unfolding, allowing for quick operation by a single person. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a foldable tire rack, which, in its unfolded working state, includes a support frame 1, a left side frame 2, a right side frame 3, and a set of connecting components. It achieves compact storage when unloaded through foldable side frames and safe, stable, multi-layer stacking when fully loaded through unique connecting components, thus solving the problems of low space utilization and poor flexibility of traditional fixed shelves.

[0026] The support frame 1 serves as the basic support platform for the tire mounting frame. It consists of a rectangular main frame and multiple parallel support tubes 101 inside. All components are preferably welded from high-strength hollow metal tubes (such as square or round steel tubes) to ensure a robust yet lightweight structure. The support frame 1 is designed to be completely open at both the front and rear, facilitating tire loading and unloading from both directions, resulting in significantly higher operational efficiency than closed frames that require side loading.

[0027] The gap 102 between the multiple parallel support tubes 101 inside the support frame 1 is smaller than the ground width of the tire to be stored, ensuring that the tire can be stably placed on it. Its ground plane is supported by multiple support tubes 101 together and will not sink into the gap, thus effectively avoiding structural deformation of the tire due to excessive local stress.

[0028] Furthermore, the support frame 1 is provided with a retaining edge 11 to prevent the tire from rolling. This prevents the tire from accidentally rolling off during storage or transportation, thus improving safety.

[0029] To further protect the expensive tire tread, an elastic buffer layer can be covered or embedded in the part of the top support tube 101 of the carrier frame 1 that is in direct contact with the tire. This buffer layer can be made of elastic materials such as rubber or polyurethane, and can prevent the hard metal tube from scratching or abrading the tire surface during handling or storage.

[0030] To facilitate handling, a carrying handle 9 can be welded to the support tube on the front and / or rear side of the bottom of the support frame 1. This allows for manual handling when a forklift is unavailable or when fine-tuning of the position is required, improving the ease of operation of the equipment.

[0031] The left and right retaining frames 2 and 3 are also constructed from welded hollow metal tubes. Unlike existing technologies, they are not rigidly welded to the main body, but are rotatably connected to the left and right sides of the support frame 1 via hinges 21 and 31, respectively. Hinges 21 and 31 can be hinges or quick-release pins (such as...). Figure 4 As shown in the diagram, the left and right retaining frames 2 and 3 are foldably connected. In this embodiment, the bottom edges of the left and right retaining frames 2 and 3 are hinged to the support frame via pins so that they can be folded together with the support frame in the non-working state. The left and right retaining frames have two defined working states: unfolded state: In this state, the left and right retaining frames 2 and 3 stand vertically perpendicular to the plane of the support frame 1, restricting the left and right movement of the tires, preventing them from slipping sideways, and ensuring storage safety.

[0032] Folded state: When empty storage or transportation is required, the left and right retaining frames 2 and 3 can be flipped inward around hinges 21 and 31, making them roughly parallel to and close to the plane of the supporting frame 1. The overall volume after folding is only a fraction of that in the unfolded state, maximizing space utilization.

[0033] The connecting components solve the stability and alignment problems of non-rigid frames when stacked.

[0034] The connecting component solves the stability and alignment problems of non-rigid frames when stacked, and includes a lower connector 6 and an upper connector 7.

[0035] For details on the implementation of the lower connector 6, please refer to [link / reference]. Figure 1 At each of the four corner points at the bottom of the support frame 1, a foot 5 is fixed. This foot 5 not only raises the frame to facilitate the insertion of forklift forks (optional design), but more importantly, a slot is fixedly provided on the lower surface of each foot 5 as a lower connector 6.

[0036] For details on the implementation of the upper connector 7, please refer to [link / reference]. Figure 2 On the horizontal hollow tubes at the top of the left and right retaining frames 2 and 3, directly opposite the lower foot 5, a positioning protrusion is provided as an upper connecting member 7. This positioning protrusion is preferably a trapezoidal shape with a smaller upper section and a larger lower section. The slot has a trapezoidal inner cavity that matches the shape of the positioning protrusion.

[0037] The stacking process is as follows Figure 4As shown: When vertical stacking is required, align the slots (lower connectors 6) on the lower surface of the upper tire holder foot 5 with the trapezoidal positioning protrusions (upper connectors 7) on the top of the side frame of the lower tire holder, and then slowly lower the tire holder and tires by their own weight. The trapezoidal conical surface provides automatic guidance, and after being fully in place, the self-locking effect of the conical surface forms a stable interference fit, effectively preventing shaking or sliding between the stacked frames. Its stacking stability and safety far exceed that of simple column tube insertion methods.

[0038] Workflow Overview

[0039] Usage process:

[0040] Unfold: Lift the left and right side frames 2 and 3 from the folded state to a vertical position, and the tire holder will be in a usable unfolded state.

[0041] Tire placement: The finished tire is placed upright on the support tube 101 of the bearing frame 1. The tire is located between the left and right guard frames and is prevented from rolling by the guard edge 11.

[0042] Stacking: Align the slots on the lower surface of the upper tire holder foot 5 with the positioning protrusions on the top of the lower tire holder side frame, and then slowly lower it under its own weight to complete the stacking. The trapezoidal mating structure can automatically guide and form a stable interference fit.

[0043] Folding: After emptying the tires, fold down the left and right side frames 2 and 3 to restore the folded state and save space for the next use.

[0044] To further improve warehouse management efficiency, a label board can be fixedly installed on the left frame 2 and / or the right frame 3. This label board can be used to affix or hang labels or cards recording information such as tire specifications, models, and batch numbers, facilitating rapid visual identification and information management within the warehouse.
