[0030] Please refer toFigures 1-5 As shown in the figure, a round belt includes: a round leather belt 1, a length adjustment belt 2, a connection structure one 3 and a connection structure two 4. The round leather belt 1 is arranged as a cylindrical belt. The length adjustment belt 2 is used for connecting the two ends of the round leather belt 1. The connection structure one 3 is arranged at both ends of the round leather belt 1. The connection structure two 4 is arranged inside the length adjustment belt 2. The connection structure two 4 includes a gasket 41, a positioning post 42, a groove 43, a mating block 44, a plugging rod 45, a spring 46 and a positioning plate 47. A groove 43 is opened inside the length adjustment belt 2. One end of the spring 46 is fixedly connected to one side wall of the groove 43, and the other end of the spring 46 is fixedly connected to the positioning plate 47. One end of the plugging rod 45 is fixedly connected to the positioning plate 47. The mating block 44 is movably sleeved outside the plugging rod 45. One side of the connection structure one 3 is clamped and arranged inside the groove 43 and extends into the inside of the mating block 44. One end of the positioning post 42 is fixedly connected to the gasket 41.

[0031] Specifically, by setting the connection structure one 3 and the connection structure two 4 to be used in cooperation, the two ends of the round belt can be detachably separated, so that the disassembly of the round belt is more convenient and fast, facilitating the quick installation of the round belt. At the same time, the length adjustment belt 2 is added. Both ends of the length adjustment belt 2 are designed in the form of jacks, so that the plug of the round belt and the jack of the length adjustment belt 2 are engaged, which can increase the length of the belt. The size of the length adjustment belt 2 can be customized to meet the situation of adjusting the wheel pitch between different pulleys, so that the length of the round belt can be adaptively adjusted, which can meet the adaptive use of the adjusted pulley and can meet the application of the round belt in actual work.

[0032] In this embodiment, the connection structure one 3 includes a connection column 31, a plug joint 32 and a positioning groove 33. The positioning groove 33 is opened inside the surface of one end of the round leather belt 1. One end of the connection column 31 is fixedly connected to one end of the round leather belt 1, and the other end of the connection column 31 is fixedly connected to the plug joint 32.

[0033] Specifically, during use, the plug joint 32 is limited and plugged into the inside of the groove 43, and the plug joint 32 is installed in cooperation with the mating block 44. Under the action of the spring 46, the plug joint 32 and the mating block 44 are closely attached to the inner wall of the groove 43, avoiding the plug joint 32 from shaking in the groove 43 and also avoiding large gaps at the plugging part due to the influence of thermal expansion and contraction when the plug joint 32 is plugged or damage caused by thermal expansion.

[0034] The positioning post 42 is movably clamped and arranged inside the positioning groove 33. One side outer wall of the gasket 41 is in contact with one end of the round leather belt 1, and the other side outer wall of the gasket 41 is in contact with one end of the length adjustment belt 2.

[0035] Specifically, the positioning post 42 is inserted into the inner wall of the positioning groove 33 to prevent the gasket 41 from rotating during use, thereby affecting the use of the round belt 1 during the operation of the equipment, and it can play a positioning role. At the same time, the gasket 41 can seal the gap between the round belt and the length adjustment belt 2 to prevent metal particles or dust from entering the inside of the length adjustment belt 2, and also avoid thermal expansion and contraction between the two.

[0036] The plug joint 32 is movably clamped inside the groove 43, and one end of the plug joint 32 is movably inserted into the inside of the mating block 44, and one end of the plugging rod 45 is clamped inside the plugging groove 34.

[0037] Specifically, the plugging rod 45 is used for limit clamping with the plugging groove 34, which can prevent the plug joint 32 from falling off, is beneficial to the quick positioning of the plug joint 32 during installation, and facilitates its quick installation.

[0038] In summary, compared with the prior art, the cylinder has at least the following beneficial effects: by setting the connection structure one 3 and the connection structure two 4 to be used in cooperation, the two ends of the round belt can be detachably separated, so that the disassembly of the round belt is more convenient and fast, facilitating the quick installation of the round belt. At the same time, the length adjustment belt 2 is added. The two ends of the length adjustment belt 2 are designed in the form of jacks, so that the plug of the round belt and the jack of the length adjustment belt 2 can be engaged, which can increase the belt length. The size of the length adjustment belt 2 can be customized to meet the situation of adjusting the wheel pitch between different belt pulleys, so that the length of the round belt can be adaptively adjusted, and it can meet the adaptive use of the adjusted belt pulley and the application of the round belt in actual work.

[0039] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
