Technical Field

[0001] This utility model relates to the field of guide wheel technology, and in particular to a detachable copper guide wheel. Background Technology

[0002] In modern industrial production and the operation of various equipment, guide wheels are key components used to guide the movement of objects such as cables, pipes, and strips. They are widely used in many fields such as machinery manufacturing, textiles, electronic equipment, packaging, and new energy.

[0003] However, in the existing technology, most guide wheels adopt an integral structure. When the surface of the guide wheel is worn or damaged, the entire guide wheel needs to be replaced, resulting in high maintenance costs. Moreover, different working conditions have different requirements for the specifications of the guide wheel. The integral guide wheel cannot quickly replace parts to adapt to different needs, resulting in poor flexibility. Although some guide wheels have a detachable structure, there are problems such as cumbersome disassembly process and insufficient stability of the connection parts. They are prone to loosening during operation, which affects the normal operation of the equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a detachable copper guide wheel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable copper guide wheel, including a hub and a wheel body, with three sets of hexagonal grooves on one side of the hub, and three sets of circular holes through one side of both the hub and the wheel body, with hexagonal bolts inserted into the three sets of circular holes, and hexagonal nuts threaded onto the outer wall of each set of hexagonal bolts, with the heads of the three sets of hexagonal nuts respectively located inside the three sets of hexagonal grooves.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1-4 As shown, this utility model provides a detachable copper guide wheel, including a hub 1 and a wheel body 2. Three sets of hexagonal grooves 6 are provided on one side of the hub 1. Three sets of round holes 7 are provided through one side of both the hub 1 and the wheel body 2. Hexagonal bolts 4 are inserted into the three sets of round holes 7. Hexagonal nuts 5 are threaded onto the outer wall of each set of hexagonal bolts 4. The heads of the three sets of hexagonal nuts 5 are respectively located inside the three sets of hexagonal grooves 6. A shaft 3 is provided on one side of the hub 1. A key body 8 is installed on the outer wall of the shaft 3. A keyway 9 is provided on the inner wall of the hub 1. The key body 8 is located inside the keyway 9. One end of the shaft 3 is inserted into the inner groove of the keyway 9.

[0022] The specific settings and functions of this embodiment are described in detail below. Three sets of hexagonal grooves 6 are evenly distributed in a 120° circle on the inner side of the hub 1. The depth of the hexagonal grooves 6 is adapted to the height of the head of the hexagonal bolt 4, forming a precise circumferential limit. At the same time, three sets of circular holes 7 are opened through the corresponding positions of the hub 1 and the wheel body 2. The diameter of the circular holes 7 is 0.5 to 1 mm larger than the diameter of the shank of the hexagonal bolt 4, ensuring that the hexagonal bolt 4 can be inserted smoothly while avoiding the connection accuracy being affected by excessive gap.

[0023] The connection and fastening method uses high-strength hexagonal bolts 4 and hexagonal nuts 5 as connecting parts. The bolt shank passes through the round hole 7 of the wheel body 2 and the round hole 7 of the hub 1 in sequence, so that the head of the hexagonal bolt 4 is completely embedded in the hexagonal groove 6 inside the hub 1. The hexagonal contour of the hexagonal groove 6 fits tightly with the head of the hexagonal bolt 4, which can effectively limit the rotation of the hexagonal bolt 4 during installation and use, and improve the connection stability. When tightening the hexagonal nut 5, the preload is controlled by a torque wrench to make the hub 1 and the wheel body 2 fit tightly.

[0024] The advantage of quick disassembly during maintenance is that the hexagonal nut 5 can be removed with a hexagonal wrench, and the hexagonal bolt 4 can be pulled out from the round hole 7 to separate the hub 1 from the wheel body 2. Compared with the traditional threaded connection, this structure reduces the number of rotations and greatly shortens the disassembly time. In addition, the positioning design of the hexagonal groove 6 and the hexagonal bolt 4 avoids the risk of the hexagonal bolt 4 falling into the equipment during the disassembly process.

[0025] The key body 8 and keyway 9 are designed such that a rectangular keyway 9 is machined on the outer wall of the shaft 3, and a through keyway 9 is opened at the corresponding position in the inner groove of the hub 1. The size of the keyway 9 is perfectly matched with the key body 8 on the shaft 3. The shaft 3 is slowly inserted into the inner groove of the hub 1 so that the key body 8 is completely embedded in the keyway 9 in the hub 1, forming a reliable circumferential constraint.

[0026] Modular maintenance: Wheel body 2, wheel hub 1, and axle 3 can be disassembled and replaced independently, greatly reducing spare parts costs;

[0027] Efficient assembly: Key components use standardized interfaces, which greatly shortens the assembly time compared to traditional structures.

[0028] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a sealing groove 10 is provided on the outer wall of the hub 1, and a sealing round gasket 11 is installed on the inner wall of the wheel body 2. The sealing round gasket 11 is located inside the sealing groove 10. Three sets of irregular gaskets 12 are installed on one side of the wheel body 2, and three sets of irregular grooves 14 are provided on the other side of the hub 1. The three sets of irregular gaskets 12 are respectively located inside the three sets of irregular grooves 14. A circular gasket 13 is installed on one side of each set of hexagonal nuts 5. Three sets of circular grooves 15 are provided on the other side of the wheel body 2, and the three sets of circular gaskets 13 are respectively located inside the three sets of circular grooves 15.

[0029] The overall effect of this embodiment is that an annular sealing groove 10 is machined on the outer wall of the hub 1, and the groove width is 0.5 to 1 mm larger than the thickness of the sealing gasket 11, forming an interference fit space. The inner wall of the wheel body 2 is provided with an installation step at the corresponding position to position the sealing gasket 11. The sealing gasket 11 is made of silicone rubber, which has good weather resistance and oil resistance. The gasket has an O-shaped cross section. After assembly, it can fill the gap between the hub 1 and the wheel body 2 through its own elastic deformation. Before installation, silicone sealant is applied to the sealing groove 10. The sealing gasket 11 is embedded into the installation step on the inner wall of the wheel body 2. Then the wheel body 2 is connected to the hub 1 so that the sealing gasket 11 is completely pressed into the sealing groove 10.

[0030] Three sets of irregularly shaped pads 12 are evenly distributed around one side of the wheel body 2 at a 120° circumference. The irregularly shaped pads 12 adopt a trapezoidal cross-section design. On the other side of the wheel hub 1, an irregularly shaped groove 14 is opened. The groove shape is perfectly matched with the irregularly shaped pads 12, forming a tenon-and-mortise sealing structure during assembly. The irregularly shaped pads 12 are made of fluororubber material, which has excellent chemical stability and anti-aging properties. The irregularly shaped pads 12 and the irregularly shaped grooves 14 work together to form a second sealing line, which can effectively block particulate dust from entering. Together with the main sealing layer, it achieves IP65 protection.

[0031] A circular washer 13 is added between the hexagonal nut 5 and the wheel body 2. Three sets of circular grooves 15 are opened at the corresponding positions of the wheel body 2. The groove width is the same as the thickness of the circular washer 13. The circular washer 13 is made of nitrile rubber, which has good wear resistance and tear resistance. During assembly, the axial pressure generated by tightening the hexagonal nut 5 causes the circular washer 13 to deform, filling the tiny gaps between the hexagonal nut 5 and the surface of the wheel body 2, preventing liquid from seeping through the hole of the hexagonal bolt 4.

[0032] Tiered protection: The triple-sealed structure forms a three-dimensional protection system of "main protection - auxiliary protection - node protection", which significantly improves the dustproof and waterproof level;

[0033] Modular maintenance: Each sealing component can be replaced independently, and the entire structure does not need to be disassembled during maintenance, greatly reducing repair time;

[0034] High adaptability: By selecting seals made of different materials, it can be adapted to various complex working conditions such as high temperature, high humidity, and corrosiveness.

[0035] The usage and working principle of this device are as follows: During the assembly process, the wheel body 2 is aligned with the wheel hub 1. The sealing round gasket 11 on the inner wall of the wheel body 2 is precisely embedded into the sealing groove 10 on the outer wall of the wheel hub 1. The elastic deformation of the sealing round gasket 11 is used to initially seal the gap between the two. At the same time, the three sets of irregular gaskets 12 on one side of the wheel body 2 and the irregular groove 14 on the other side of the wheel hub 1 interlock with each other to form a tenon and mortise sealing structure, which further enhances the sealing effect.

[0036] Then, three sets of hexagonal bolts 4 are passed through the corresponding circular holes 7 on the wheel body 2 and the wheel hub 1 in sequence, so that the head of the hexagonal bolt 4 is inserted into the hexagonal groove 6 on the inner side of the wheel hub 1. The hexagonal contour of the hexagonal groove 6 fits tightly with the bolt head, restricting the circumferential rotation of the bolt. The hexagonal nut 5 is tightened by a hexagonal wrench. Between the nut and the wheel body 2, the annular washer 13 is pressed into the annular groove 15, filling the gap between the hexagonal nut 5 and the surface of the wheel body 2, preventing liquid from seeping through the hole of the hexagonal bolt 4. As the hexagonal nut 5 is tightened, the hexagonal bolt 4 generates axial tension, so that the wheel hub 1 and the wheel body 2 fit tightly together, achieving a stable connection and ensuring that the two will not be displaced relative to each other during the operation of the guide wheel.

[0037] Finally, the shaft 3 is inserted into the inner groove of the hub 1, so that the key body 8 is fully embedded in the keyway 9 of the inner groove of the hub 1. The tight fit between the key body 8 and the keyway 9 forms a reliable circumferential constraint. When the shaft 3 is driven to rotate by an external force, the torque is transmitted to the hub 1 through the key body 8. The hub 1 then drives the wheel body 2, which is fixedly connected to it, to rotate synchronously, thereby realizing the function of the guide wheel in guiding the movement trajectory of objects such as cables and pipes.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
