Description

Technical Field

[0001] This utility model belongs to the field of tire rim manufacturing equipment; specifically, it relates to a variable diameter rim storage rack. Background Technology

[0002] With the rapid development of the automotive industry and the continuous growth of people's travel needs, the demand for tires is also increasing year by year. To meet this growing market demand, tire manufacturers need to continuously improve production efficiency while ensuring product quality. The tire rim is a crucial component of a tire, playing a vital role in its structure and function. Its design, manufacturing, and installation quality directly affect tire performance and lifespan, as well as vehicle safety and comfort.

[0003] In the field of tire rim manufacturing equipment, the storage and management of rims has always been a crucial factor affecting production efficiency and product quality. With the rapid development of the tire manufacturing industry, the demand for rim storage racks is also increasing. These racks are required not only to store rims safely and stably, but also to be able to accommodate rims of different specifications and diameters.

[0004] Traditional tire rim storage racks are mostly fixed in design, meaning their diameter and height are fixed and cannot be adjusted according to the size of the rims. This design presents several inconveniences in practical applications. For example, due to the diverse specifications of tire rims, fixed storage racks often cannot simultaneously accommodate multiple sizes, leading to low storage efficiency and wasted space. Furthermore, when storing rims of different diameters, fixed racks can result in gaps that are too large or too small between the rim and the rack, affecting storage stability and potentially damaging the rims.

[0005] At the work site, specialized storage racks of corresponding sizes are typically provided for steel rims of different sizes. However, the current operating procedure is inefficient: whenever it is necessary to change the storage rack for a different model of steel rim, workers must first push the rack that fits the original steel rim size back to the warehouse, and then retrieve the rack that fits the new steel rim size from the warehouse. This back-and-forth process is cumbersome and significantly affects work efficiency. Utility Model Content

[0006] In response to the problem that there is no single type of storage rack that can accommodate steel rims of different sizes during the tire rim production process, this utility model provides a steel rim storage rack with a variable diameter.

Therefore, they should not be construed as limitations on this utility model.

[0026] As attached Figure 1-2 As shown, a variable diameter steel ring storage rack includes a base 1 for supporting the entire structure. The base 1 preferably has at least three sets of casters at its bottom for easy transport.

[0027] The base 1 is fixedly connected to the top of the support rod 11, which is preferably vertically arranged. The support rod 11 is fixedly connected to the fixing rod 12, which is horizontally arranged. The fixing rod 12 preferably extends from the top of the fixing rod 12 to both sides.

[0028] At least two crossbeams 13 are arranged in a circumferential array along the axis of the fixed rod 12, preferably three, and the adjacent crossbeams 13 form an angle of 50° to 80° based on the axis of the fixed rod 12. The crossbeams 13 are arranged parallel to the fixed rod 12, and the crossbeams 13 are fixedly connected to the support rod 11. The support rod 11 extends outward and is fixedly connected to the crossbeams 13.

[0029] A through hole 131 is provided on the crossbeam 13. The through hole 131 is preferably arranged radially along the fixed rod 12. An adjusting rod 21 is slidably arranged in the through hole 131. One end of the adjusting rod 21 is fixedly connected to the support member 2, and the other end of the adjusting rod 21 extends to the side with a pin 22. The support member 2 can be an arc-shaped plate as shown in the figure, or a soft support block, or other structures, used to contact and support the steel ring.

[0030] As attached Figure 3-5 As shown, the driven gear 3 is rotatably connected to the fixed rod 12, and grease is applied between them to ensure smooth rotation. The fixed rod 12 may be provided with a rotating groove to accommodate the driven gear 3, or limiters may be provided on both sides of the driven gear 3 to prevent displacement. An adjustment hole 31 is provided on the side of the tooth body of the driven gear 3. The adjustment hole 31 extends along the circumference of the driven gear 3 from the direction close to the tooth body axis to the direction away from the tooth body axis. The number and position of the adjustment holes 31 correspond to the crossbeam 13. Specifically, the number of adjustment holes 31 can be greater than the number of crossbeams 13. The included angle between adjacent adjustment holes 31 based on the axis of the driven gear 3 is equal to the included angle between adjacent crossbeams 13 based on the axis of the fixed rod 12, so that the adjustment range of multiple support members 2 is similar; the pin 22 is slidably connected in the adjustment hole 31, and grease is applied between them to ensure smooth rotation, so that as the driven gear 3 rotates, the pin 22 is driven away from or closer to the axis of the driven gear 3. Each driven gear 3 is connected to an adjustment rod 21 for each crossbeam 13, that is, as shown in the figure, one driven gear 3 is connected to three adjustment rods 21.

[0031] It also includes a rotation drive mechanism for driving the driven gear 3 to rotate, and a locking element 8 for limiting the rotation of the driven gear 3 is detachably connected to the rotation drive mechanism.

[0032] Furthermore, the rotation drive mechanism includes a rotating shaft 5 rotatably connected to the fixed rod 12. The rotating shaft 5 passes through the body of the fixed rod 12 and is rotatably connected. The rotating shaft 5 is arranged parallel to the fixed rod 12. The drive gear 4 is fixedly connected to the rotating shaft 5. Preferably, the rotating shaft 5 has a keyway to ensure a stable connection with the pinion 4 through the key, thereby achieving effective torque transmission. The drive gear 4 meshes with the driven gear 3. A rocker handle 6 is provided at one end of the rotating shaft 5. The rocker handle 6 can be integrally fixedly connected to the rotating shaft 5, or it can be formed by machining an internal hexagonal groove at the end of the rotating shaft 5 and inserting it into an external hexagonal structure machined at one end of the rocker handle 6.

[0033] Further details are attached. Figure 6 As shown, the other end of the rotating shaft 5 is provided with a non-circular slot structure, and the locking member 8 is U-shaped. One end of the U-shaped locking member 8 is provided with a mounting hole 81 that mates with the fixing rod 12. The mounting hole 81 can be a circular through hole. The other end of the U-shaped locking member 8 is provided with a plug 82 that mates with the non-circular slot structure at the end of the rotating shaft 5. The plug 82 is preferably an external hexagonal structure, and the other end of the rotating shaft 5 is an internal hexagonal groove that mates with the external hexagonal structure. When the support member 2 is adjusted to the specified position or size, the external hexagonal end of the locking member 8 is inserted into the internal hexagonal hole at the other end of the rotating shaft 5, and at the same time, the through hole end is inserted into the fixing rod 12 on the base 1, thereby realizing the locking function and ensuring that the support member 2 will not retract when bearing the weight of the steel ring.

[0034] Furthermore, an adjustment mechanism is formed by the driven gear 3, the driving gear 4 meshing with it, and at least two adjusting rods 21 connected to the driven gear 3 via a pin 22. At least two adjustment mechanisms are provided along the length of the fixed rod 12.

[0035] The present invention can produce the following beneficial effects

This design enables the rack to accommodate steel rings of different sizes, significantly improving storage flexibility and space utilization.

[0037] 2. Enhanced Stability and Safety: The three sets of crossbeams on the base 1 are arranged in a 60° circle, which not only ensures the smooth movement of the support ring 2 but also enhances the stability of the entire storage rack. In addition, the design of the self-locking crank 8 ensures that the support ring 2 can be firmly locked after reaching the specified size, preventing the support ring 2 from retracting due to the weight of the steel ring, thereby ensuring storage safety.

[0038] 3. Simplified Operation: Users can easily adjust the diameter of the support ring 2 using the convenient operation of the crank 6 and locking element 8, without the need for complicated tools or procedures.
