[0002] The turntable bearing seat is a large and extra-large bearing seat with a special structure that can withstand comprehensive loads. It has the characteristics of compact structure, sensitive rotation, and easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is commonly known as the bearing seat.

[0003] The patent specification with announcement number CN221857344U discloses a bearing with a bearing seat, including a base, a bearing body and a fixing mechanism, wherein a fixing mechanism is provided on the top of the base and the bearing body is installed inside the fixing mechanism, and the fixing mechanism includes a card cover, a through groove, a plug rod, a limit groove, a slide groove, a spring and a latch, and the two ends of the bottom of the card cover are integrally formed with a plug rod inserted into the through groove, and a limit groove is provided on the bottom side of the plug rod surface. The bearing body is installed between the base and the card cover. After the bearing body is installed in place, the card cover is closed, the plug rod is inserted into the through groove, and the latch is pulled so that the bottom of the plug rod can be inserted into the bottom end of the through groove until the limit groove is aligned with the end of the slide groove. Then, the reset latch end is inserted into the limit groove to fix the base position and thus complete the fixation of the bearing body position. When disassembly is required, the card cover can be removed by simply pulling the latch horizontally. It is convenient to install and disassemble and more convenient to use.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device needs to use a bolt to rotate and twist the installation method during use, which is relatively inconvenient in the actual disassembly and assembly process. If the disassembly and assembly volume is large, it will further consume manpower costs and time costs, which is not conducive to improving work efficiency. Therefore, further improvement is needed.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, this embodiment proposes a spline shaft bearing seat, including a welding plate 1, a connecting plate 2 is fixedly connected to the bottom of the welding plate 1, a bearing seat body 3 is provided at the bottom of the connecting plate 2, a plurality of long plates 4 are fixedly connected to the outside of the bearing seat body 3, the bottoms of the plurality of long plates 4 are fixedly connected to a column 5, a plurality of mounting plates 6 are fixedly installed at the bottom of the connecting plate 2, the bottoms of the plurality of mounting plates 6 are fixedly connected to a square plate 7, the bottoms of the plurality of square plates 7 are fixedly connected to a shell 8, a plurality of shells 8 are provided with a sliding rod 9 inside, a plurality of sliding rods 9 are fixedly connected to a support plate 10 at one end of the top, and a plurality of support plates 10 are fixedly connected to an adapter shell 11 on the outside.

[0029] In this embodiment, the bearing seat body 3 is located at the axial center of the connecting plate 2, and the multiple long plates 4 and columns 5 are distributed in a circular shape, which can facilitate the installation of the spline shaft.

[0030] In this embodiment, the plurality of slide bars 9 are respectively connected to the plurality of housings 8 in a sliding manner. The shape of the slide bars 9 is configured to be a zigzag shape, which can facilitate the sliding of the slide bars 9 inside the housing 8 .

[0031] In this embodiment, the multiple adapting shells 11 are respectively arranged outside the multiple pillars 5, and the interiors of the multiple adapting shells 11 are respectively in contact with the outer surfaces of the multiple pillars 5, which makes it easy for the adapting shells 11 to limit the pillars 5.

[0032] During use, when the connecting plate 2 needs to be fixed, the staff first needs to move the bearing seat body 3 to the axial position of the connecting plate 2, and then rotate the bearing seat body 3. The bearing seat body 3 will synchronously drive the long plate 4 to rotate during the rotation. When the long plate 4 drives the column 5 to rotate to the same plane as the adapter shell 11, the staff will lower the bearing seat body 3. The bearing seat body 3 will synchronously drive the long plate 4 and the column 5 to move downward during the lowering process. The column 5 will enter the interior of the adapter shell 11 during the movement and then be supported by the support plate 10, so that the bearing seat body 3 can be fixed. At this time, there is a certain gap between the long plate 4 and the connecting plate 2.

[0033] In order to facilitate further stabilization of the bearing seat body 3, the staff needs to lift the sliding rod 13 upward. During the lifting process, the sliding rod 13 will synchronously drive the sliding shell 12 and the sliding rod 9 to move upward. Then the staff will pull out the sliding rod 13 and insert it into the slot position inside the shell 8. During this process, the sliding rod 9 will drive the support plate 10 and the adapter shell 11 to move upward. During the upward movement of the support plate 10, it will synchronously drive the column 5 and the long plate 4 to rise upward and fit into the bottom of the connecting plate 2, thereby achieving the fixing effect of the bearing seat body 3 and facilitating the stability of the bearing seat body 3.

[0034] Example 2

[0035] like Figure 3~Figure 4 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes that the exteriors of multiple sliding rods 9 are fixedly connected to sliding shells 12 , and the multiple sliding shells 12 are respectively located at the bottoms of multiple housings 8 , which can facilitate the connection of the sliding shells 12 .

[0036] In this embodiment, the interiors of the plurality of sliding shells 12 are all slidably connected to the sliding rods 13 , and the interiors of the plurality of housings 8 are all provided with card slots to facilitate the sliding operation of the sliding rods 13 .

[0037] In this embodiment, the plurality of sliding rods 13 extend into the interior of the plurality of card slots and contact therewith respectively. The plurality of sliding rods 13 are all configured to be U-shaped, which can facilitate the sliding engagement of the sliding rods 13 .

[0038] In this embodiment, a rotating shell 14 is provided at the bottom of the connecting plate 2 . The rotating shell 14 is connected to the connecting plate 2 via a damping bearing, which facilitates the rotation of the rotating shell 14 .

[0039] In this embodiment, a plurality of shift plates 15 are fixedly connected to the outside of the rotating shell 14 . The shift plates 15 are arranged in an arc shape, which facilitates the connection of the shift plates 15 .

[0040] In this embodiment, a plurality of guide plates 16 are fixedly connected to the interior of the rotating shell 14 . The guide plates 16 are located on one side of the sliding rod 13 , so that the guide plates 16 can drive the sliding rod 13 to move.

[0041] During use, when it is necessary to dismantle and maintain the bearing seat body 3 or the spline shaft, the staff needs to toggle the dial plate 15. During the toggling process, the dial plate 15 will synchronously drive the rotating shell 14 to rotate, and the rotating shell 14 will synchronously drive the guide plate 16 to rotate during the rotation. The guide plate 16 will drive the sliding rod 13 to move outward during the rotation, and the sliding rod 13 will leave the slot inside the shell 8 during the movement, and then the bearing seat body 3 will fall down due to its own weight due to unlocking. During the falling process, the bearing seat body 3 will synchronously drive the long plate 4 and the column 5 to move downward, and during the downward movement of the column 5, the support plate 10, the adapter shell 11 and the slide rod 9 will synchronously drive downward to slide. When there is a gap between the long plate 4 and the connecting plate 2, the staff will lift the bearing seat body 3 and rotate the long plate 4 and the column 5 to take them out.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
