According to the utility model discloses a further embodiment, be provided with the chamfer including the inner circle and the outer lane outside.

According to the utility model discloses a further embodiment, be provided with flexible guide arm in further including the spring, flexible guide arm one end and fixed column connection, the flexible guide arm other end and mounting groove are connected.

According to the utility model discloses a further embodiment, further be provided with the guide rail on the mounting groove inner wall, be provided with the guide slot that agrees with the guide rail on the fixed column.

According to the utility model discloses a further embodiment, further be provided with the draw-in groove on the fixed column, be provided with the fixture block that agrees with the draw-in groove in the fixed slot.

According to the utility model discloses a further embodiment, be provided with the lubricant film including the outer lane is inboard and the inner circle outside.

The utility model has the advantages that: the utility model discloses a simple structure is reliable, has increased anti-drop's function through the cooperation of mounting groove, fixed column, spring and fixed slot under the condition that functional structure does not reduce, and fundamentally has stopped ball obscission in the assembling process, has improved the machining efficiency of product greatly, has guaranteed product quality, has reduced manufacturing cost.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is an enlarged schematic structural diagram of the utility model a.

In the figure, the device comprises an inner ring 1, an outer ring 2, an outer ring 3, a ball 4, a retainer 5, a mounting groove 6, a fixing column 7, a spring 8, a fixing groove 9, a dust cover 10, a sealing groove 11, a chamfer 12, a telescopic guide rod 13, a guide rail 14, a guide groove 15, a clamping groove 16 and a clamping block.

Detailed Description

Fig. 1 is the utility model discloses a schematic structure diagram, an anti-drop bearing, including inner circle 1, outer lane 2, set up ball 3 between inner circle 1 and outer lane 2 and be used for the cover to establish the holder 4 that is used for fixing in the ball 3 outside, characterized by, be provided with fixing device on the 4 inner walls of holder, as shown in fig. 2, fixing device includes mounting groove 5, fixed column 6 and spring 7, and mounting groove 5 sets up on the 4 inner walls of holder, and fixed column 6 passes through spring 7 and mounting groove 5 to be connected, is provided with the fixed slot 8 that agrees with fixed column 6 on the ball 3. The utility model discloses a simple structure is reliable, has increased anti-drop's function through the cooperation of mounting groove 5, fixed column 6, spring 7 and fixed slot 8 under the condition that functional structure does not reduce, and fundamentally has stopped ball obscission in the assembling process, has improved the machining efficiency of product greatly, has guaranteed product quality, has reduced manufacturing cost.

Two dust covers 9 are arranged between the outer ring 2 and the inner ring 1, the dust covers 9 are arranged on two sides of the retainer 4, and sealing grooves 10 matched with the end parts of the dust covers 9 are arranged on the inner ring 1 and the outer ring 2.

The outer sides of the inner ring 1 and the outer ring 2 are provided with chamfers 11, the chamfers 11 ensure stable installation of the bearing, and abrasion of the edge of the bearing is reduced.

A telescopic guide rod 12 is arranged in the spring 7, one end of the telescopic guide rod 12 is connected with the fixed column 6, and the other end of the telescopic guide rod 12 is connected with the mounting groove 5. And a guide rail 13 is arranged on the inner wall of the mounting groove 5, and a guide groove 14 matched with the guide rail 13 is arranged on the fixing column 6. The telescopic guide rod 12 and the matching of the guide rail 13 and the guide groove 14 prevent the fixed column 6 from being clamped when being telescopic.
