Abstract
The invention discloses a kind of ball slide rail structures, including sliding rail, ball, retainer and fixed block, two retainers are respectively fixedly connected on the upper and lower end face of a fixed block, several fixed blocks are plugged in sliding rail, it is placed on a ball in each retainer, ball contradicts on the inner wall of sliding rail.The configuration of the present invention is simple, movement is smooth, and convenient for manufacture, mechanical wear is small, and using effect is good.
Description
Technical field:
The present invention relates to a kind of ball slide rail structures.
Background technique:
Existing subway door track is mostly sliding block slide rail type structure, and after using the section time, the mechanical wear of track is big, long
It can be become larger therewith using rear structural failure long, influence using effect, or even can have security risk.Therefore, it is necessory to existing
There is technology to improve to solve the deficiency of the prior art.
Summary of the invention:
The present invention is to provide a kind of ball slide rail structure to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has: a kind of ball slide rail structure, including sliding rail, ball, retainer and fixation
Block, two retainers are respectively fixedly connected on the upper and lower end face of a fixed block, several fixed blocks are plugged in sliding rail,
It is placed on a ball in each retainer, ball contradicts on the inner wall of sliding rail.
Further, the sliding rail is tool there are two the U-shape structure of slide and a connection side, and two slides are mutually flat
Row setting, is equipped with V-arrangement slideway in each slide, and the inside 90 ° of bendings in the end of each slide simultaneously form vertical rib.
Further, the retainer is the structure of right angle tyoe with vertical edge and horizontal sides, and the vertical edge of retainer welds
It connects on fixed block, is equipped with retaining hole on the horizontal sides, ball is placed in retaining hole.
The invention has the following beneficial effects:
The configuration of the present invention is simple, movement is smooth, and convenient for manufacture, mechanical wear is small, and using effect is good.
Detailed description of the invention:
Fig. 1 is structure of the invention figure.
Fig. 2 is the structure chart of sliding rail in the present invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
Such as Fig. 1 and Fig. 2, a kind of ball slide rail structure of the present invention, including sliding rail 1, ball 2, retainer 3 and fixed block 4, two
Retainer 3 is respectively fixedly connected on the upper and lower end face of a fixed block 4, several fixed blocks 4 are plugged in sliding rail 1, each
It is placed on a ball 2 in retainer 3, ball 2 contradicts on the inner wall of sliding rail 1.
Sliding rail 1 in the present invention is tool there are two the U-shape structure of slide and a connection side, and two slides are parallel to each other
Setting, is equipped with V-arrangement slideway 11 in each slide, and ball 2 is placed in V-arrangement slideway 11.Slideway is v-shaped structure, can be to ball 2
It is limited well.
Further to limit to ball 2, ball 2 is avoided to be detached from from sliding rail 1, the end of each slide in sliding rail 1
Inside 90 ° of bendings simultaneously form vertical rib 12.
Retainer 3 is the structure of right angle tyoe with vertical edge and horizontal sides, and the vertical edge of retainer 3 is welded on fixed block 4
On, it is equipped with retaining hole on the horizontal sides, ball 2 is placed in retaining hole.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
