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.

[0029] The utility model provides Figure 1-4 A roller bearing cage structure shown includes a frame 1, and a plurality of frames 1 are provided with isolation columns 2;

A clamping mechanism 4 is arranged inside the isolation column 2, and the clamping mechanism 4 includes: a clamping rod 41, a first compression spring 42, a pull block 43 and an anti-falling component 44. A through groove is opened in the middle of the isolation column 2, and multiple clamping rods 41 are slidably and interlacedly connected with the inner cavity of the through groove. A clamping hole is opened on the opposite side of the multiple skeletons 1, and the clamping rod 41 is slidably and interlacedly connected with the inner cavity of the clamping hole; the two ends of the first compression spring 42 are respectively fixedly connected to the multiple clamping rods 41. The first compression spring 42 is always in a compressed state, thereby providing a stable elastic force to the multiple clamping rods 41, and the connecting plate 3 limits the multiple skeletons 1 in the vertical direction. The clamping rod 41 is clamped with the clamping hole under the elastic force, thereby limiting the multiple skeletons 1 in the horizontal direction, so that the multiple skeletons 1 and the multiple isolation columns 2 can be spliced ​​together to form a complete bearing retainer; the multiple pulling blocks 43 are respectively fixedly connected to the multiple clamping rods 41, and the outer wall of the isolation column 2 is provided with a pulling groove. The pulling block 43 is slidably and interlaced with the inner cavity of the pulling groove. The clamping rod 41 can be pulled by the pulling block 43 so that the clamping rod 41 is detached from the clamping hole to complete the disassembly of the isolation column 2, and the operation is simple and convenient; the anti-fall-off component 44 is arranged inside the isolation column 2.

[0031] Specifically, the anti-falling component 44 includes: an extrusion plate 441, a blocking rod 442, an extrusion rod 443, a second compression spring 444 and an L-shaped rod 445.

A groove is provided on the outer wall of the pull block 43, and a slide groove is provided on the bottom end of the inner wall of the groove.
