[0023] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The present invention provides a chain device that is easy to install. Figure 1-6 As shown, the chain device that is easy to install includes: a protective shell 2 arranged on the outside of the gear body 1, a chain body 3 is wound on the outside of the gear body 1, and the chain body 3 is engaged with the gear body 1; a support rod 4, the support rod 4 is rotatably mounted on the inner wall of the protective shell 2; a support wheel 5, the support wheel 5 is rotatably mounted on the support rod 4 and can contact the chain body 3, and the support wheel 5 is provided with a limiting groove 18 for clamping the chain body 3; a clamping plate 6, the clamping plate 6 is fixed on the protective shell 2, and the clamping plate 6 is used to support the support rod 4; a support assembly, the support assembly is arranged on the clamping plate 6, and the support assembly is used to support the lifted support rod 4.

[0025] In this embodiment, the gear body 1, as the core component of the chain transmission, is mounted inside the protective shell 2. The protective shell 2 not only provides physical protection for the gears and chains, but also constitutes the outer shell of the entire device. The chain body 3 is wound on the gear body 1 and maintains an engaged state with the gear body 1 to realize power transmission. Through the design of the support wheel 5 and the limit groove 18, the user can easily guide the chain body 3 to the correct position without directly touching the chain body 3 and the gear body 1, which greatly reduces the difficulty and risk of installation. When the support rod 4 is lowered, the card plate 6 provides stable support, effectively preventing the support rod 4 from directly contacting the chain body 3 below without an unlimited structure and affecting its normal movement.

[0026] In a further preferred embodiment of the present invention, the support assembly includes an adjusting bolt 7, a support plate 8 and a shock-absorbing pad 9, the adjusting bolt 7 is threadedly mounted on the clamping plate 6, the support plate 8 is mounted on the top of the adjusting bolt 7, and the shock-absorbing pad 9 is fixed on the top of the support plate 8 and can contact the support rod 4.

[0027] In this embodiment, the position of the adjusting bolt 7 on the clamping plate 6 can be adjusted by rotating the adjusting bolt 7. This design provides a high degree of flexibility and adjustability. The rotating installation of the support plate 8 provides additional stability for the chain installation process. The shock-absorbing pad 9 is usually made of a soft and wear-resistant material, such as rubber or silicone, which effectively reduces the vibration between the support rod 4 and the support plate 8 and extends the service life of the components. At the same time, it can also provide a certain buffering effect during the installation process of the chain body 3 to protect the chain body 3 and the gear body 1 from damage.

[0028] In a further preferred embodiment of the present invention, the chain body 3 is composed of multiple chain accessory components, and the chain accessories are composed of two fixed plates 10, two shafts 11, two first sleeves 12, two first connecting plates 13 and two second connecting plates 14. The two shafts 11 are rotatably installed between the two fixed plates 10, the two first sleeves 12 are respectively sleeved on the two shafts 11, the two first connecting plates 13 are rotatably installed on any one of the first sleeves 12, the two second connecting plates 14 are rotatably installed on the other first sleeve 12, and the second sleeves 22 are rotatably installed between the two first connecting plates 13 and the two second connecting plates 14.

[0029] In this embodiment, the fixed plate 10 serves as the basic support of the entire chain structure, firmly fixing the two shafts 11 and providing a stable framework for the rotation of the chain. The shaft 11 is the main rotation axis in the chain structure, allowing the chain to rotate flexibly in a specific direction. The first sleeve 12 protects the shaft 11 from wear and tear, and also serves as a bridge connecting the first connecting plate 13 and the second connecting plate 14, making the entire chain structure more compact and easy to assemble. The second sleeve 22 serves as an additional connection point, which not only enhances the stability between the connecting plates, but also can cooperate with other shafts 11 to extend the length of the chain. Through modular design, the components are connected by the rotation of the sleeve and the shaft 11, making the assembly and disassembly of the chain simple and quick, reducing maintenance costs and time. The design of multiple rotating connections makes the chain more stable during rotation, reducing the risk of failure due to loose or worn components.

[0030] In a further preferred embodiment of the present invention, threaded holes are provided on the two first sleeves 12, the two second sleeves 22 and the two shafts 11, and multiple fixing bolts 16 are threadedly installed in the threaded holes respectively located on the two first sleeves 12 and the two second sleeves 22, and the multiple fixing bolts 16 extend into the threaded holes located on the two shafts 11 respectively.

[0031] In this embodiment, the design of the threaded hole provides the necessary connection point for the subsequent installation of the fixing bolt 16, making the connection between the components more secure. By tightening the bolt, the sleeve and the shaft rod 11 are tightly connected together, preventing the relative movement or loosening of the sleeve on the shaft rod 11, thereby ensuring the stability of the chain structure during operation. Through the threaded connection, the fit between the fixing bolt 16 and the threaded hole is tighter and not easy to loosen or fall off, thereby improving the reliability of the chain structure. When it is necessary to disassemble or replace parts, it can be easily completed by loosening the fixing bolt 16, which simplifies the maintenance process and reduces maintenance costs. Since the installation position of the fixing bolt 16 can be adjusted according to actual needs, the chain structure can adapt to the installation requirements under different working environments, improving its applicability and flexibility.

[0032] In a further preferred embodiment of the present invention, two grooves 15 are provided on each of the two first shaft sleeves 12 and the two second shaft sleeves 22 , and the plurality of fixing bolts 16 are respectively located in the plurality of grooves 15 .

[0033] In this embodiment, the groove 15 not only provides a positioning space for the fixing bolt 16, but also makes the entire sleeve structure more compact and beautiful. This layout not only ensures the stability and firmness of the fixing bolt 16, but also avoids the protrusion of the bolt on the sleeve surface, reduces the risk of damage due to accidental collision or friction, and improves the overall aesthetics of the chain structure. Placing the fixing bolt 16 in the groove 15 can effectively reduce the direct contact between the bolt and the external environment, reduce the risk of bolt damage due to corrosion, wear and other reasons, and extend the service life of the bolt.

[0034] In a further preferred embodiment of the present invention, two limiting grooves 18 are provided on the fixing plate 10 , and first limiting plates 19 are provided in the two limiting grooves 18 . The two first limiting plates 19 are fixedly connected to the two shafts 11 respectively.

[0035] In this embodiment, the limit groove 18 is used to limit the movement range of the first limit plate 19, so that the shaft 11 can maintain a certain axial stability during the rotation process, preventing the chain structure from being unstable or damaged due to axial movement. By limiting the axial movement of the shaft 11, the safety hazards caused by the movement of the shaft 11, such as chain breakage and falling off, are reduced, thereby improving the safety of the entire chain structure. This limiting method does not require additional complex mechanisms or components, and can be achieved only through a simple limit groove 18 and limit plate design, which simplifies the overall design of the chain structure and reduces manufacturing costs. Since the structure of the limit groove 18 and the limit plate is relatively simple, it is also more convenient and quick during daily maintenance or replacement of components.

[0036] In a further preferred embodiment of the present invention, multiple inner grooves are provided on both sides of the first connecting plate 13 and the second connecting plate 14, and second limit plates 20 are provided in the multiple inner grooves. The two first shaft sleeves 12 and the two second shaft sleeves 22 are both between the multiple second limit plates 20.

[0037] In this embodiment, the first connecting plate 13 and the second connecting plate 14 serve as key connecting components in the chain structure. Their stability and position accuracy are crucial to the performance of the entire chain. The inner groove provides an installation position for the second limit plate 20, thereby achieving further limitation of the shaft sleeve. The clamping effect of the second limit plate 20 on the shaft sleeve effectively limits the movement of the shaft sleeve on the connecting plate, reducing the instability of the chain caused by loose components. No complex additional mechanism is required. An effective limiting effect can be achieved through the simple design of the inner groove and the second limit plate 20, which simplifies the overall design of the chain structure. When components need to be disassembled or replaced, it can be easily completed by loosening the fixing bolts 16 and removing the second limit plate 20, reducing the difficulty and cost of maintenance.

[0038] In a further preferred embodiment of the present invention, the two first sleeves 12 and the two second sleeves 22 are each provided with an inner compartment 21 allowing the shaft 11 to pass through, the plurality of fixing bolts 16 can respectively extend into the plurality of inner compartments 21, the plurality of limiting grooves 18 and the inner walls of the plurality of inner grooves are smeared with lubricating oil, and the plurality of fixing bolts 16 are each provided with a limiting opening 17 matching a hexagonal wrench.

[0039] In this embodiment, the inner bin 21 not only provides the necessary installation space for the shaft 11, but also ensures that the sleeve can be tightly mounted on the shaft 11 to prevent relative sliding or dislocation. In the process of the fixing bolts 16 passing through the threaded holes on the sleeve and connecting with the threaded holes on the shaft 11, they will further extend into the interior of the inner bin 21. This design allows the fixing bolts 16 to not only contact the surfaces of the sleeve and the shaft 11, but also penetrate into the internal space of the sleeve, thereby providing a more secure and stable connection, optimizing the compactness and aesthetics of the chain structure, and applying lubricating oil for While reducing the frictional resistance between components, the first limit plate 19 and the second limit plate 20 can move more smoothly in the limit groove 18 and the inner groove. At the same time, the heat and wear generated by friction are reduced, and the service life of the components is extended. The setting of the limit mouth 17 facilitates the tightening and loosening operations of the fixing bolt 16, allowing maintenance personnel to use a standard hexagonal wrench to quickly complete the tightening and disassembly of the bolt, thereby improving work efficiency. The design of the limit mouth 17 also ensures that the bolt can be evenly stressed during the tightening process, preventing damage or loosening of the bolt due to uneven force.

[0040] To sum up, compared with the relevant technology, the present device can support the chain body 3 when installing it by setting the support rod 4 and the support wheel 5, and guide the chain body 3 to the correct position, thereby facilitating the installation of the chain body 3. By setting the first shaft sleeve 12 and the second shaft sleeve 22 in conjunction with multiple shafts 11, multiple fixed plates 10, first connecting plates 13 and second connecting plates 14 can be connected together in sequence. The shaft 11 and the first shaft sleeve 12 and the second shaft sleeve 22 are stabilized by the fixing bolt 16 to facilitate the assembly and disassembly of the various components of the chain, realize flexible adjustment of the chain length, and also facilitate the initial installation of the chain.
