Detailed Description

The utility model provides a miniature linear slide rail join in marriage and connect structure. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.

A matching structure of a miniature linear slide rail is shown in figures 1 and 2 and comprises a slide rail 1 and a slide seat 2, wherein a circulating pipeline carrying balls 3 is arranged in the slide seat 2.

wherein, the both sides of slide rail 1 are equipped with respectively and are used for the slide 4 that matches with ball 3 and join in marriage, and arbitrary slide 4 includes two segmental arcs 5 with ball 3 matched with and lies in indent end 6 between two segmental arcs 5, and the central angle of arbitrary segmental arc 5 is < 60.

two ends of the sliding seat 2 are respectively provided with a dustproof clapboard 7, and the dustproof clapboard 7 is provided with a blocking piece 8 of the type corresponding to the slideway 4.

Specifically, the conventional slideway 4 is in a semi-circular arc shape, and has a large contact surface with the balls 3, so that dust particles are greatly abraded between the contact surfaces after dust accumulation.
