Description

A kind of linear slide rail with reflux unit

Technical field

The utility model relates to linear slide rail technical field, especially a kind of linear slide rail with reflux unit.

Background technique

The mobile linear slide rail of sliding block is generally provided, in order to reduce the mobile coefficient of friction of sliding block and reduce sliding block movement When noise generate, therefore can all be arranged between sliding block and sliding rail return-flow system provide ball-recirculation rolling.

The return-flow system of linear slide rail generally comprises rolling element, return flow line and the cap assemblies etc. that flow back, and existing linear cunning Deficiency existing for the return-flow system of rail is: first is that, the reflux of the return-flow system of existing linear slide rail is covered using a monolith Design, thus reflux groove hardly possible of the machine-shaping for return flow line turning is covered in reflux；Second is that existing linear slide rail The reflux of return-flow system covers tightly be fixed in sliding block after, big with the frictional force of line rail when following sliding block to slide, the fortune of linear slide rail Efficiency of movement is low；Third is that the matched return flow line hole location on the reflux groove of the return-flow system of existing linear slide rail and sliding block Hardly possible alignment, the packaging efficiency of linear slide rail are low.

In existing correlative technology field, still lack the preferred version for solving above-mentioned technical problem.

Utility model content

The technical issues of the utility model solves be for above-mentioned the problems of the prior art, provide a kind of frictional force it is small, Sport efficiency is high and assembling is easily with the linear slide rail of reflux unit.

To solve above-mentioned technical problem, a kind of technical solution that the utility model is taken is as follows: one kind having reflux unit Linear slide rail, including line rail is formed with rolling groove on the two sidewalls of the line rail longitudinal direction, and sliding is installed on cunning on the line rail Block, the two sides of the sliding block longitudinal direction and rolls and is all provided with the first rolling groove on the position of groove face, the rolling groove and the One, which rolls groove docking, constitutes the first circular groove, and the two sides of the sliding block longitudinal direction are also formed with to be extended simultaneously along sliding block transverse direction Second circular groove of perforation；It is equal positioned at first circular groove of sliding block longitudinal direction the same side and the transverse ends of the second circular groove A reflux cap assemblies are installed with, its aperture and the first circular groove or the second circular groove hole are formed on each reflux cap assemblies The semicircular arc-shaped reflux groove that diameter matches, the two reflux groove docking matched first positioned at sliding block longitudinal direction the same side Circular groove and the second circular groove simultaneously match the backflash for constituting closure, are equipped with to recycle along backflash in the backflash and roll Dynamic rolling element, the rolling element is dynamic along rolling channel trough roller, and matching slides rail along sliding block.

It is further described as to above-mentioned technical proposal:

In the above-mentioned technical solutions, the reflux cap assemblies include reflux upper cover and reflux bottom cover；The reflux upper cover and Reflux bottom cover is formed with scarf, and the reflux upper cover is formed with semicircular arc-shaped first time with recessed on the scarf for the bottom cover that flows back Groove is flowed, the reflux upper cover is formed with tenon column with convex on the scarf for the bottom cover that flows back, and the tenon column is to insertion system at reflux bottom Mortise on lid and reflux upper cover matching position, matching, which makes to flow back upper cover, and the bottom cover mortise-tenon joint that flows back flows back cap assemblies and makes Two first reflux grooves are butted into the semicircular arc-shaped reflux groove.

In the above-mentioned technical solutions, the reflux groove and first reflux the matched semicircle arc dia of groove be 6mm~ 8mm, first circular groove, the second circular groove, flow back groove aperture be 5mm~6mm, the rolling element be sphere diameter For the ball of 5mm~6mm.

In the above-mentioned technical solutions, the end that the reflux groove is docked with the second circular groove is also formed with the heavy platform of extension Convex, the both ends of each second circular groove transverse direction are formed with sink hole, and the heavy platform tuck pointing enters matched sink hole, and leads to To flow back cap assemblies and sliding block of bolt is crossed to fasten, matching make to flow back cap assemblies and sliding block it is affixed and make the second circular groove and flow back Groove docking.

In the above-mentioned technical solutions, the end that the reflux groove is docked with the first circular groove is also formed with contact portion, described Contact portion is defined as front end close to one end of sliding block, and one end far from sliding block is defined as rear end, and the lateral surface of the contact portion is The outer front end described without leave of arcwall face, the arcwall face of the contact portion is gradually reduced to the rear end；The reflux cap assemblies with When sliding block fastens and follows rail sliding along sliding block, the contact portion is movably embedded in the rolling groove and it is located at front end Arcwall face and roll groove sliding contact.

In the above-mentioned technical solutions, the rolling groove is minor arc shape sliding channel, and described first rolls groove as major arc Shape sliding channel.

Compared with prior art, the utility model has the beneficial effects that: first is that, the linear slide rail of the utility model is in cunning Linearly extended first is formed on block and rolls groove and the second circular groove, and straight line processing first rolls groove and the second round ditch Slot is easy, is high in machining efficiency；Second is that by the cap assemblies that flow back be set as reflux upper cover that two connects inserting structure by Tenon and time Bottom cover is flowed, the first reflux groove of type semi arch is made in scarf fovea superior of the upper cover with the bottom cover that flows back that flow back respectively, avoids Machine-shaping reflux groove, reduces difficulty of processing in monolith reflux lid, and flow back upper cover and reflux bottom cover are using scarf structure Cooperate joinery and its construction connection, reflux upper cover and reflux bottom cover fixation；Third is that reflux groove and the second circular groove are by sinking Platform convex cooperates sink hole docking, and reflux groove is docked by the contact portion of gradual change type with the first circular groove, is easy to backflash Hole location alignment, improve the packaging efficiency of linear slide rail；Fourth is that contact portion uses gradual change type cambered surface, reduces contact portion and roll The contact of groove, and then friction is reduced, the sport efficiency of linear slide rail is high.
