An axial hole is also provided on the fixing plate, and four claws are provided in the circumference of the axial hole. The claws are used to fix the box bottom to the frame. When the bearing seat is disassembled and maintained, there is no need to disassemble the box bottom, which is convenient and quick; the cover plate is designed to be U-shaped, which can facilitate the addition of lubricating oil to the bearing seat. The protective structure used in this application is relatively simple, and the protective cover cannot be conveniently opened and closed freely. The operation of maintaining and cleaning the bearing is cumbersome, which reduces the practicality of this protective cover. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a new bearing protective cover, which aims to improve the protective structure adopted by the traditional bearing protective cover, which is relatively simple and cannot be opened and closed freely and conveniently. The maintenance and cleaning of the bearing are cumbersome, which reduces the practicality of this protective cover.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of bearing protective cover, including a cover body, a plurality of cover covers are rotatably connected to the top of the cover body, a plurality of fixing seats are fixedly connected to the side walls of the cover body, a fixing plate is fixedly connected to the side walls of the cover body, a rotating column is rotatably connected to the inside of the fixing plate, a plurality of screws are threadedly connected to the inside of the rotating column, a sleeve column is fixedly connected to the outer wall of the rotating column, a rotating wheel is fixedly connected to the outer wall of the sleeve column, a turntable is rotatably connected to one end of the screw at the top, a rotating rod is rotatably connected to the inside of the turntable, a connecting plate is fixedly connected to the side wall of the connecting plate, and a fixing component is provided on the side walls of the cover body.

[0006] Furthermore, the fixing assembly includes a second connecting plate, and a plurality of the second connecting plates are fixedly connected to the side wall of the cover body.

[0007] Furthermore, each of the second side walls of the connecting plate is rotatably connected to a second turntable, and a connecting shaft is rotatably connected inside the second turntable.

[0008] Furthermore, one end of the connecting shaft is fixedly connected to a connecting column, a spring 1 is arranged inside the connecting column, and a supporting plate is fixedly connected to the side wall of the cover body.

[0009] Furthermore, one end of the connecting column is rotatably connected to a turntable three.

[0010] Furthermore, the three side walls of the turntable are fixedly connected with connection blocks, and the side walls of the connection blocks are fixedly connected with connection disks.

[0011] Furthermore, the side wall of the connection plate is fixedly connected with a side column, and the outer wall of the side column is sleeved with a second spring.

[0012] Furthermore, the support plate is fixedly connected to the side wall of the cover body, and the side column is slidably connected inside the support plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the rotating wheel is firstly driven to rotate the sleeve column inside it, and the sleeve column then drives the rotating column to rotate inside the sleeve column. While the rotating column rotates, multiple screws are displaced, thereby changing the inclination angle of the turntable, and then driving the inclination angle of the rotating rod to change, so that the cover is pulled up from the top of the cover body. Due to this structure, the protective cover can be opened and closed freely, which facilitates the inspection and maintenance of the bearing and improves the maintenance efficiency and practicality of the protective cover.

The connecting columns on both sides are simultaneously subjected to force to cushion the protective cover. At the same time, the side column slides inside the support plate and the spring two is set to further cushion the protective cover. This structure enhances the protective function of the protective cover and provides a guarantee for the normal operation of the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a new bearing protection cover, including a cover body 1, a plurality of cover covers 2 are rotatably connected to the top of the cover body 1, a plurality of fixing seats 3 are fixedly connected to the side wall of the cover body 1, a fixing plate 4 is fixedly connected to the side wall of the cover body 1, a rotating column 5 is rotatably connected inside the fixing plate 4, a plurality of screws 6 are threadedly connected inside the rotating column 5, a sleeve column 7 is fixedly connected to the outer wall of the rotating column 5, a rotating wheel 8 is fixedly connected to the outer wall of the sleeve column 7, a turntable 9 is rotatably connected to one end of the top screw 6, a rotating rod 10 is rotatably connected to the inside of the turntable 9, a connecting plate 11 is fixedly connected to the side wall of the rotating rod 10, and the connecting plate 11 is fixedly connected to the side wall of the cover cover 2, and a fixing component is provided on the side wall of the cover body 1.

[0023] Specifically, the movement of the rotating wheel 8 causes the sleeve 7 to start rotating, and the rotation of the sleeve 7 drives the rotation of the rotating column 5. The rotating column 5 is threadedly connected to the screw rods 6 at both ends, so that the screw rods 6 are displaced. The displacement of these screw rods 6 causes the horizontal position of the turntable 9 to change. As the position of the turntable 9 changes, the rotating rod 10 starts to rotate inside it and changes its own inclination angle accordingly. This angle change in turn drives the connecting plate 11 to apply a pulling force to the cover 2, so that the cover 2 starts to rotate on the top of the cover body 1. The coordinated rotation of multiple cover covers 2 ultimately leads to the opening and closing state inside the cover body 1. The design of this mechanism greatly improves the maintenance efficiency and practicality of the protective cover, and provides convenience for the inspection and maintenance of the bearing.

[0024] Reference Figure 3The fixing component includes a connecting plate 2 12, and multiple connecting plates 2 12 are fixedly connected to the side wall of the cover body 1. The side wall of each connecting plate 2 12 is rotatably connected to a turntable 2 13, and the turntable 2 13 is rotatably connected to a connecting shaft 14. One end of the connecting shaft 14 is fixedly connected to a connecting column 15, and a spring 16 is arranged inside the connecting column 15. The side wall of the cover body 1 is fixedly connected to a supporting plate 22, and one end of the connecting column 15 is rotatably connected to a turntable 3 17. The side wall of the turntable 3 17 is fixedly connected to a connecting block 18, and the side wall of the connecting block 18 is fixedly connected to a connecting disk 19. The side wall of the connecting disk 19 is fixedly connected to a side column 20, and the outer wall of the side column 20 is provided with a spring 21. The supporting plate 22 is fixedly connected to the side wall of the cover body 1, and the side column 20 is slidably connected to the inside of the supporting plate 22.

[0025] Specifically, when the protective cover is impacted by external force, the connecting block 18 first drives the side column 20 to slide inside the support plate 22 through the movement of the connecting plate 19 to buffer the force. At the same time, the setting of the spring 21 ensures that the connecting block 18 can be quickly reset, providing a guarantee for the system to return to normal state. The movement of the connecting block 18 will also cause the turntable 3 17 on its side wall to rotate, thereby affecting the angle of the connecting column 15. The change in the angle of the connecting column 15 will drive the connecting shaft 14 to rotate inside the turntable 2 13, thereby achieving the reset and adjustment of the protective cover. At the same time, through the setting of the springs 16 on both sides, the impact force caused by the external force impact can be effectively buffered to protect the bearing from damage. Such a structural design greatly enhances the protective function of the protective cover, ensures the normal operation of the bearing under the impact of external force, and provides reliable protection for the equipment.

[0026] Working principle: when it is necessary to open the cover 2 to inspect and maintain the bearing inside the cover body 1, first rotate the rotating wheel 8. The rotating wheel 8 drives the sleeve column 7 inside it to rotate while rotating, and the sleeve column 7 then drives the rotating column 5 inside it to rotate along with it. Through the threaded connection relationship between the rotating column 5 and the screw rods 6 at both ends of the rotating column 5, while the rotating column 5 rotates, multiple screw rods 6 rotate and move at both ends of the rotating column 5. The horizontal position of the turntable 9 is changed by the displacement of the screw rod 6, which then drives the rotating rod 10 to rotate inside the turntable 9 and change its own inclination angle. The movement of the rotating rod 10 drives the connecting plate 11 of its side wall to pull the cover 2, so that the cover 2 rotates on the top of the cover body 1. The rotation of multiple cover covers 2 can achieve the purpose of adjusting the cover body 1. The opening and closing of the part facilitates the inspection and maintenance of the bearing, and improves the maintenance efficiency and practicality of the protective cover. When the protective cover is impacted by external force, the connecting block 18 first drives the connecting disk 19 to move after being subjected to force, and makes the side column 20 slide inside the support plate 22, and the setting of the spring 21 enables it to be quickly reset. While the connecting block 18 moves, the turntable 3 17 of its side wall drives the connecting column 15 to rotate. After the angle of the connecting column 15 is changed, it drives the connecting shaft 14 to rotate inside the turntable 2 13, and at the same time, it can be buffered by the setting of the springs 16 on both sides. Therefore, the protective function of the protective cover is improved by this structure, which prevents the bearing from being unable to work due to damage due to external force, and provides a guarantee for the normal operation of the bearing.
