[0022] like Figures 1-4 As shown, the utility model provides a technical solution: a pulley with an axial fixing function, comprising a pulley body 1, a rotating shaft 2 is provided on the side of the pulley body 1, and the pulley body 1 is installed by pushing it toward the rotating shaft 2, an installation mechanism 3 is provided on the pulley body 1 and the rotating shaft 2, and a stabilizing mechanism 4 is provided on the pulley body 1 and the rotating shaft 2.
[0023] In this embodiment, a mounting mechanism 3 is provided on the pulley body 1 and the rotating shaft 2. By sliding the guide rod 31 in the mounting mechanism 3 inside the guide groove 32, it is possible to prevent displacement during the installation process. By snapping the end of the mounting block 34 into the interior of the mounting groove 36, pre-installation can be completed to prevent displacement. By pushing the mounting block 34 to release the snapping, the pulley body 1 can be easily disassembled and replaced.
[0024] In this embodiment, a stabilizing mechanism 4 is provided on the pulley body 1 and the rotating shaft 2. By pulling the end of the support rod 44 by the supporting plate 41 in the stabilizing mechanism 4, the slider 43 can be moved toward the center direction of the pulley body 1. By engaging the clamping block 46 with the inside of the clamping groove 47, the installation between the pulley body 1 and the rotating shaft 2 can be made more stable. The elastic force of the compression spring 42 can make the supporting plate 41 move to the left for reset, thereby facilitating the disassembly of the pulley body 1.
[0025] The above-mentioned mounting mechanism 3 includes a guide rod 31, which is fixedly mounted on the inner wall of the pulley body 1. A guide groove 32 is provided on the outer wall of the rotating shaft 2. The guide groove 32 is located on the side of the guide rod 31. By sliding the guide rod 31 inside the guide groove 32, it can prevent deviation during the installation process. A mounting block 34 is slidably connected to the outer wall of the pulley body 1. The end of the mounting block 34 is set to an inclined surface. By squeezing the inclined surface of the mounting block 34 through the outer wall of the end of the rotating shaft 2, the mounting block 34 can be moved away from the pulley body. The body 1 moves in the direction of the center position for easy installation. The side wall of the mounting block 34 is fixedly connected to one end of the load-bearing spring 33, and the other end of the load-bearing spring 33 is fixedly connected to the inner wall of the pulley body 1. The elastic force of the load-bearing spring 33 can make the end of the mounting block 34 snap into the inside of the mounting groove 36 to complete the pre-installation and prevent deviation. The internal thread of the mounting block 34 is connected with a fastening bolt 35, and the fixed installation can be completed by tightening the fastening bolt 35. A mounting groove 36 is provided on the rotating shaft 2, and the mounting groove 36 is located on the side of the mounting block 34.
[0026] The above-mentioned stabilizing mechanism 4 includes a bearing plate 41, which is slidably connected to the inner wall of the pulley body 1, and the bearing plate 41 is fixedly connected to one end of a compression spring 42, and the other end of the compression spring 42 is fixedly connected to the inner wall of the pulley body 1. The elastic force of the compression spring 42 can make the bearing plate 41 move to the left for resetting, and a slider 43 is slidably connected to the inner wall of the pulley body 1. The slider 43 is hinged to one end of a support rod 44, and the other end of the support rod 44 is hinged to the bearing plate 41. By pulling the end of the support rod 44 by the bearing plate 41, the slider can be reset. The block 43 moves toward the center direction of the pulley body 1, and an arc-shaped plate 45 is fixedly installed on the outer wall of the slider 43. The arc-shaped plate 45 is set to an arc shape. A clamping block 46 is fixedly installed on the outer wall of the arc-shaped plate 45. The clamping block 46 is arranged in an array on the outer wall of the arc-shaped plate 45. A clamping groove 47 is opened on the rotating shaft 2. The clamping groove 47 is adapted to the size of the clamping block 46. The clamping groove 47 is located on the side of the clamping block 46. The slider 43 drives the clamping block 46 on the outer wall of the arc-shaped plate 45 to be clamped into the inside of the clamping groove 47, which can make the installation between the pulley body 1 and the rotating shaft 2 more stable.
[0027] The guide rod 31 slides inside the guide groove 32 to prevent the pulley body 1 from deviating during the installation process. At the same time, the outer wall of the end of the rotating shaft 2 squeezes the inclined surface of the mounting block 34, so that the mounting block 34 moves in the direction away from the center position of the pulley body 1, thereby facilitating the movement of the rotating shaft 2 into the interior of the pulley body 1 for installation. The elastic force of the supporting spring 33 is then used to make the end of the mounting block 34 engage with the interior of the mounting groove 36, completing the pre-installation to prevent deviation. During installation, the outer wall of the supporting plate 41 is squeezed by the rotating shaft 2, so that the supporting plate 41 compresses the compression spring 42 and moves to the right, thereby The carrier plate 41 pulls the end of the support rod 44, and then the support rod 44 is hinged with the slider 43 to move toward the center of the pulley body 1, and then the slider 43 drives the block 46 on the outer wall of the arc plate 45 to move toward the outer wall of the rotating shaft 2, so that the block 46 is engaged with the inside of the groove 47, making the installation between the pulley body 1 and the rotating shaft 2 more stable. Finally, the fixed installation is completed by tightening the fastening bolt 35. When the pulley body 1 needs to be disassembled, the fastening bolt 35 is loosened, and the clamping is released by pushing the mounting block 34. At this time, the elastic force of the compression spring 42 causes the carrier plate 41 to move to the left for reset, and then the rotating shaft 2 is pushed by the carrier plate 41 to facilitate the disassembly of the pulley body 1.
[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
