Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of detachable Ball retainer, packet
The pressing plate 2 of 1 side institute Matching installation of bracket 1 and bracket is included, the main body of bracket 1 is circular ring type structure, and is equipped in 1 side of bracket
The mounting groove 101 of arc-shaped waist type structure, is equipped with spacer column 102 between two adjacent fitting grooves 101, on the end face of spacer column 102
Equipped with connecting screw hole 103, Matching installation has the supporting block 4 of waist type structure in mounting groove 101；
The both ends of supporting block 4 are equipped with the positioning surface 403 of waist type structure, and the intermediate position of supporting block 4 is equipped with spherical shell knot
The spherical shell 402 of structure is equipped with the spherical surface 401 of spherical structure in spherical shell 402, and Matching installation has bearing ball 5 in spherical surface 401；
The main body of pressing plate 2 set by 1 side of bracket is annular plate-like structure, and is equipped in 2 side side of pressing plate around pressing plate 2
The connection counterbore 201 that the center of circle circumferentially uniformly arranges；
Be equipped with attachment screw 3 in connecting screw hole 103 on 102 end face of spacer column, attachment screw 3 with connect 201 phase of counterbore
Set is matched, and bracket 1 is fixed together with pressing plate 2 by attachment screw 3, and this structure facilitates supporting block 4 in mounting groove 101
Installation and replacement.
Further, mounting groove 101 is circumferentially uniformly arranged in 1 side of bracket, so that the bearing rolling in entire retainer
