Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model provides a jump ring connection type holder structure, as shown in fig. 3, including holder seat 5 and holder lid 4 and jump ring 6, with outer lane 1, inner circle 2, rolling element 3, holder lid 4 and holder seat 5 equipment back, block jump ring 6 to holder lid 4 and holder seat 5 corresponding recess in, block holder seat 5 and holder lid 4, constitute complete holder structure.

As shown in fig. 4, the holder cover 4 is a ring-shaped structure, and a through hole 401 having a shape matching with the pillar projection 503 of the holder base 5 is formed at a position corresponding to the pillar projection 503 so that the pillar projection 503 is inserted into the through hole 401, and the height of the pillar projection 503 is the same as the height of the holder cover 4. The inner diameter side surface of the holder cover 4 is in a ring groove structure, a second empty groove 402 is processed between the inner end surface and the outer end surface, the second empty groove 402 is a ring groove along the circumference of the inner diameter side surface of the holder cover 4, the second empty groove 402 is positioned at the height center position of the holder cover 4, and the second empty groove 402 is communicated with the through hole 401.

As shown in fig. 5, the holder base 5 includes a circular end surface 501, the circular end surface 501 is an integral structure in which pillars 502 are uniformly connected at intervals, the end of each pillar 502 is a columnar projection 503, a first empty groove 504 is formed on a side surface of the columnar projection 503 facing a center of a circle, the first empty groove 504 is a long groove penetrating in a circumferential direction and is located at a height center position of the columnar projection 503, and a groove width of the first empty groove 504 is the same as a width of the second empty groove 402.

When the holder base 5 and the holder cover 4 are connected in an aligned manner, the first empty slot 504 is located just outside the second empty slot 402 in the radial direction, the second empty slot 402 and the first empty slot 504 form a continuous slot, and the clamp spring 6 is installed in the slot to clamp and fix the holder base 5 and the holder cover 4.
