The object of the invention is to the above problem overcoming prior art existence, a kind of three joint rails are provided, use minimum material to bring high-strength supporting capacity.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of three joint rails, comprise a pair outer rail and be arranged at the middle rail between a pair outer rail, described middle rail forms an i shaped cross section by the frange plate at web and two ends, be provided with the boss with described middle rail side-fit inside described outer rail, inside described frange plate and between described boss, be provided with load-carrying ball.
Further, a pair auxiliary ball is respectively arranged with between described web both sides and described boss.
Further, escape groove is offered in the middle of described boss.
Further, the ball grooves with described load-carrying ball engagement is offered inside described frange plate with on described boss.
Further, described web both sides and described boss offer the ball grooves with described auxiliary ball engagement.
Preferably, between described middle rail height a, described frange plate width b, described web height c, described web thickness d, described frange plate thickness e, relational expression is:
a/b＝1.5～3；
d/b＝0.15～0.4；
c/a＝0.5～0.9；
e＝1/2(aa-c)。
Preferably, ball retainer is respectively arranged with between the load-carrying ball of described middle rail both sides and auxiliary ball.
The invention has the beneficial effects as follows:
1, the middle rail of i shaped cross section takes into account good mechanical property and less materials'use amount.
2, the weight between outer rail and middle rail born by load-carrying ball, and auxiliary ball plays the effect of auxiliary positioning, steady slide rail.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
