Description

Clamping rail

Technical Field

The utility model relates to a linear slide rail is related to the field, especially relates to a clamp rail.

Background

In the case of a linear slide rail, when a slide block is about to enter or exit the slide rail, a rolling element (such as a ball or a roller) is liable to fall out of the slide block, so that the rolling element is not separated arbitrarily under the retaining effect of the clamping rail by the aid of the clamping rail.

The conventional linear guideway is generally divided into two different types, i.e. a front-to-back (DF) type and a back-to-back (DB) type, in order to cope with the two different types of linear guideway, a worker in the art must develop different molds to manufacture different clamping rails, but this inevitably increases the cost of developing the molds, and also takes a lot of time to confirm whether the clamping rails are corresponding during assembly. The related patent documents like TW I263001, TW I441989, or JPA — 2002106560 do not have a solution to effectively solve the problem that the clamping rail cannot be shared.
