Description

Technical Field

[0001] This utility model relates to the field of aluminum disc technology, and in particular to a material-saving high-strength aluminum disc. Background Technology

[0002] In exercise bikes, the aluminum disc is an important component, and its material and performance have a direct impact on the fitness effect and user experience. Aluminum alloys are widely used in the manufacture of flywheels or chainrings of exercise bikes due to their excellent properties such as light weight, high strength, and corrosion resistance.

[0003] In most existing exercise bikes, the aluminum disc is mounted on the axle of the exercise bike and connected to the pedals via a crank. When the user steps on the pedals, the crank drives the disc to rotate, which in turn generates resistance in conjunction with a magnet, thus achieving different exercise intensities.

[0004] During use, the disc needs to be regularly lubricated between the disc and the axle of the exercise bike to reduce the possibility of rust and facilitate disassembly later. However, due to the narrow gap between the disc and the axle, it may be necessary to disassemble the disc to add lubricant, which can make the process cumbersome and time-consuming, affecting the lubrication efficiency of the disc. Utility Model Content

[0005] The technical problem this invention aims to solve is that, due to the narrow gap between the disc and the shaft, personnel may need to disassemble and reassemble the disc during the process of adding lubricating oil, which makes the process of adding lubricating oil cumbersome and time-consuming, thus affecting the lubrication efficiency of the disc.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a material-saving high-strength aluminum disc, including a disc body, the disc body is divided into an inner ring and an outer ring, an oiling device is provided on one side of the inner ring of the disc body to quickly lubricate the gap between the disc body and the connecting shaft of the exercise bike, and a connecting device is provided between the inner ring and the outer ring to allow the inner ring and the outer ring to be disassembled and freely replaced.

[0007] The effect achieved by the above components is as follows: First, the disc is assembled on the connecting shaft of the exercise bike, and at the same time, it is connected to the pedals via the crank. When the person steps on the pedals, the crank drives the disc to rotate, which then works with the magnet to generate resistance, thereby achieving different exercise intensities.

[0008] Preferably, the oiling device includes a slot formed on one side of the inner ring, the inner wall of the slot having a first threaded groove, the inner wall of the slot having a plurality of first through holes, a hollow ring slidably connected to the inner wall of the slot, the inner wall of the hollow ring having a plurality of second through holes, a first round hole block fixedly connected to one side of the hollow ring, a first bolt provided inside the first round hole block, the surface of the first bolt being threadedly connected to the inner wall of the first threaded groove, a feed pipe fixedly connected to one side of the hollow ring, and a sealing cap threadedly connected to the surface of the feed pipe.

[0009] The effect achieved by the above components is as follows: By setting up an oiling device, the hollow ring is first manually moved, causing the hollow ring to drive the first circular hole block to move. When the hollow ring moves to the position where it is fully engaged in the slot, the first circular hole block enters the slot, making the inner wall of the first circular hole block coincide with the inner wall of the first threaded groove. At this time, the first bolt is rotated by a tool, causing the first bolt to rotate into the position of the first circular hole block and the first threaded groove, fixing the position of the first circular hole block and the hollow ring, thus achieving the assembly of the hollow ring with the inner ring of the disc. At this time, lubricating oil is injected into the disc through the feed pipe. Inside the hollow ring, the inlet of the feed pipe is then sealed with a sealing cap. When the disc rotates, the lubricating oil inside the hollow ring is discharged through multiple second through holes. Subsequently, the lubricating oil is discharged through multiple first through holes and falls into the gap between the disc and the shaft, thereby achieving lubrication of the gap between the disc and the shaft. This allows personnel to quickly add lubricating oil to the gap between the disc and the connecting shaft without disassembling the disc, reducing the operation steps and time required for adding lubricating oil and improving the lubrication efficiency and convenience of the disc.

[0010] Preferably, the surface of the sealing cover is fixedly connected with a plurality of anti-slip strips, and the plurality of anti-slip strips are arranged at equal intervals.

[0011] The effect achieved by the above components is that by setting anti-slip strips, the friction between the hand and the sealing cover can be increased, reducing the chance of the hand slipping when manually turning the sealing cover.

[0012] Preferably, a viewing hole is provided on one side of the hollow ring, and a transparent plate is fixedly connected to the inner wall of the viewing hole.

[0013] The effect achieved by the above-mentioned components is that by setting a viewing hole, personnel can observe the amount of lubricating oil stored inside the hollow ring through the viewing hole and the transparent plate, thereby improving the convenience of personnel to add oil.

[0014] Preferably, the inner wall of the hollow ring is fixedly connected with a plurality of guide plates, and the plurality of guide plates are arranged at equal intervals.

[0015] The effect achieved by the above components is as follows: by setting the guide plate, the guide plate can rotate along with the disk body during rotation, and at the same time, the lubricating oil inside the hollow ring that is far from the second round hole is guided to the position closer to the second round hole, thereby improving the discharge efficiency of the lubricating oil.

[0016] Preferably, the inner wall of the hollow ring is symmetrically fixedly connected with two sealing strips.

[0017] The effect achieved by the above components is that by setting a sealing strip, the sealing strip can fill and seal the gap between the hollow ring and the inner wall of the groove, reducing the leakage of lubricating oil through the gap.

[0018] Preferably, the connecting device includes a rectangular groove formed on one side of the inner ring, a second threaded groove formed on the inner wall of the rectangular groove, a second circular hole block fixedly connected to the inner wall of the outer ring, the surface of the second circular hole block being slidably connected to the inner wall of the rectangular groove, a second bolt being provided inside the second circular hole block, and the surface of the second bolt being threadedly connected to the inner wall of the second threaded groove.

[0019] The aforementioned components achieve the following effects: By setting up a connecting device, the outer ring is first manually moved, causing the outer ring to move the second circular hole block. When the outer ring moves to the position where it fits onto the surface of the inner ring, the second circular hole block is inserted into the rectangular groove, making the inner wall of the second circular hole block coincide with the inner wall of the second threaded groove. At this time, the second bolt is rotated by a tool, causing the second bolt to rotate into the position of the second circular hole block and the second threaded groove to fix the position of the second circular hole block and the outer ring, thus achieving the assembly of the outer ring and the inner ring. At the same time, the severely worn inner ring or outer ring can be disassembled and replaced separately in the future, reducing the material waste caused by the later maintenance of the disc and improving the convenience and flexibility of the maintenance disc.

[0020] Preferably, an auxiliary groove is provided on one side of the second circular hole block, and the inner wall of the auxiliary groove is larger than the surface of the second bolt.

[0021] The effect achieved by the above-mentioned components is that by setting the auxiliary groove, the nut of the second bolt can be completely inserted into the auxiliary groove for storage, reducing the situation where the surface of the second bolt is higher than the disc and affects it.

[0022] The beneficial effects of this utility model are:

[0023] By incorporating an oiling device, personnel can quickly add lubricating oil to the gap between the disc and the connecting shaft without disassembling the disc body. This reduces the number of steps and time required for adding lubricating oil, and improves the efficiency and convenience of lubrication of the disc body. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figure 1-4 The material-saving high-strength aluminum disc shown includes a disc body 1, which is divided into an inner ring 11 and an outer ring 12. An oiling device 2 is provided on one side of the inner ring 11 of the disc body 1 to quickly lubricate the gap between the disc body 1 and the connecting shaft of the exercise bike. A connecting device 3 is provided between the inner ring 11 and the outer ring 12 to allow for disassembly and free replacement of the inner ring 11 and the outer ring 12. First, the disc body 1 is assembled on the connecting shaft of the exercise bike, and at the same time, it is connected to the pedal by a crank. When the person steps on the pedal, the crank drives the disc body 1 to rotate, which then cooperates with the magnet to generate resistance, thereby achieving different exercise intensities.

[0033] Figure 2 and Figure 3The oiling device 2 shown includes a slot 21 on one side of the inner ring 11. The inner wall of the slot 21 has a first threaded groove 22 and multiple first through holes 23. A hollow ring 24 is slidably connected to the inner wall of the slot 21. The inner wall of the hollow ring 24 has multiple second through holes 25. A first circular hole block 26 is fixedly connected to one side of the hollow ring 24. A first bolt 27 is provided inside the first circular hole block 26, and the surface of the first bolt 27 is threadedly connected to the inner wall of the first threaded groove 22. A feed pipe 28 is fixedly connected to one side of the hollow ring 24, and a sealing cap 29 is threadedly connected to the surface of the feed pipe 28. By setting up the oiling device 2, the hollow ring 24 is first manually moved, causing the hollow ring 24 to move the first circular hole block 26. When the hollow ring 24 moves to the position where it is fully engaged inside the slot 21, the first circular hole block 26 enters the slot 21, causing the inner wall of the first circular hole block 26 to engage with the first threaded groove. When the inner walls of the first ring 24 and the first circular hole block 26 and the first threaded groove 22 are aligned, the first bolt 27 is rotated by a tool to fix the position of the first circular hole block 26 and the hollow ring 24, thus assembling the hollow ring 24 with the inner ring 11 of the disc body 1. At this time, lubricating oil is injected into the hollow ring 24 through the feed pipe 28. Then, the inlet of the feed pipe 28 is sealed with the sealing cap 29. When the disc body 1 rotates, the lubricating oil inside the hollow ring 24 is discharged through multiple second circular through holes 25. Then, the lubricating oil is discharged through multiple first circular through holes 23 and falls into the gap between the disc body 1 and the shaft, thereby achieving lubrication treatment of the gap between the disc body 1 and the shaft. This allows personnel to quickly add lubricating oil to the gap between the disc body 1 and the connecting shaft without disassembling the disc body 1, reducing the operation steps and time when adding lubricating oil and improving the lubrication efficiency and convenience of the disc body 1.

[0034] Figure 2 and Figure 3 Multiple anti-slip strips 210 are fixedly connected to the surface of the sealing cover 29 shown. The multiple anti-slip strips 210 are arranged at equal intervals. By setting the anti-slip strips 210, the friction between the hand and the sealing cover 29 can be increased, reducing the possibility of slipping when manually rotating the sealing cover 29. A viewing hole 211 is opened on one side of the hollow ring 24. A transparent plate is fixedly connected to the inner wall of the viewing hole 211. By setting the viewing hole 211, personnel can observe the amount of lubricating oil inside the hollow ring 24 through the viewing hole 211 and the transparent plate, improving the convenience of personnel to add oil.

[0035] Figure 2 and Figure 3The hollow ring 24 shown has multiple guide plates 212 fixedly connected to its inner wall. The guide plates 212 are arranged at equal intervals. By setting the guide plates 212, the guide plates 212 can rotate with the disc 1 during rotation. At the same time, the lubricating oil inside the hollow ring 24 that is far from the second through hole 25 is guided to a position closer to the second through hole 25, thereby improving the discharge efficiency of the lubricating oil. Two sealing strips 213 are symmetrically fixedly connected to the inner wall of the hollow ring 24. By setting the sealing strips 213, the sealing strips 213 can fill and seal the gap between the hollow ring 24 and the inner wall of the slot 21, reducing the leakage of lubricating oil through the gap.

[0036] Figure 3 and Figure 4 The connecting device 3 shown includes a rectangular groove 31 formed on one side of the inner ring 11. A second threaded groove 32 is formed on the inner wall of the rectangular groove 31. A second circular hole block 33 is fixedly connected to the inner wall of the outer ring 12. The surface of the second circular hole block 33 is slidably connected to the inner wall of the rectangular groove 31. A second bolt 34 is provided inside the second circular hole block 33, and the surface of the second bolt 34 is threadedly connected to the inner wall of the second threaded groove 32. By setting the connecting device 3, the outer ring 12 is first manually moved, causing the outer ring 12 to move the second circular hole block 33. When the outer ring 12 moves to the position where it fits onto the surface of the inner ring 11... When the second circular hole block 33 is inserted into the rectangular groove 31, the inner wall of the second circular hole block 33 coincides with the inner wall of the second threaded groove 32. At this time, the second bolt 34 is rotated by a tool, so that the second bolt 34 is rotated into the position of the second circular hole block 33 and the second threaded groove 32 to fix the position of the second circular hole block 33 and the outer ring 12, thereby achieving the assembly of the outer ring 12 and the inner ring 11. At the same time, the severely worn inner ring 11 or outer ring 12 can be disassembled and replaced separately in the future, reducing the material waste caused by the later maintenance of the disc 1 and improving the convenience and flexibility of the maintenance disc 1.

[0037] Figure 3 and Figure 4 The second circular hole block 33 shown has an auxiliary groove 35 on one side. The inner wall of the auxiliary groove 35 is larger than the surface of the second bolt 34. By setting the auxiliary groove 35, the nut of the second bolt 34 can be completely inserted into the auxiliary groove 35 for storage, reducing the situation where the surface of the second bolt 34 is higher than the disc body 1 and affects it.

[0038] Working principle: First, manually move the hollow ring 24, causing it to move the first circular hole block 26. When the hollow ring 24 is fully engaged in the slot 21, the first circular hole block 26 enters the slot 21, aligning its inner wall with the inner wall of the first threaded groove 22. Then, rotate the first bolt 27 using a tool, moving it into position within the first circular hole block 26 and the first threaded groove 22 to position the first circular hole block 26 and the hollow ring 24. The hollow ring 24 is fixed and assembled with the inner ring 11 of the disc body 1. At this time, lubricating oil is injected into the hollow ring 24 through the feed pipe 28. Then, the inlet of the feed pipe 28 is sealed with the sealing cap 29. When the disc body 1 rotates, the lubricating oil inside the hollow ring 24 is discharged through multiple second round through holes 25. Then, the lubricating oil is discharged through multiple first round through holes 23 and falls into the gap between the disc body 1 and the shaft, thereby achieving lubrication treatment of the gap between the disc body 1 and the shaft.

[0039] First, manually move the outer ring 12 so that it moves the second circular hole block 33. When the outer ring 12 moves to the position where it fits on the surface of the inner ring 11, the second circular hole block 33 is inserted into the rectangular groove 31, so that the inner wall of the second circular hole block 33 coincides with the inner wall of the second threaded groove 32. At this time, use a tool to rotate the second bolt 34 so that the second bolt 34 is rotated into the position of the second circular hole block 33 and the second threaded groove 32 to fix the position of the second circular hole block 33 and the outer ring 12, thus achieving the assembly of the outer ring 12 and the inner ring 11. At the same time, the severely worn inner ring 11 or outer ring 12 can be disassembled and replaced separately in the future.
