Existing a kind of patent No. is that CN20112027928.6 name is called that the Chinese utility model patent of " linear slide block " discloses a kind of linear slide block, it comprises a pedestal, two circulators and two or more roller, this base-plates surface is molded a covering material, covering material is provided with the load rail and zero load rail that roll away for this roller carrying over linear slide block direction of linear motion, and covering material forms and draws anchor between the outer surface and inner surface of the inside and outside subtend of pedestal; This circulator includes interior rail chair and outer rail chair, simple and easy embedding group of inside and outside rail chair is fixed on outside the covering material of pedestal two side ends, making interior rail chair and outer rail chair coupling take group defines for the pivotal cyclic track of roller and oil duct, and this cyclic track is connected conducting load rail and zero load rail.But its complex structure, produce, assemble inconvenience, therefore its structure need further improvement.
Summary of the invention
Technical problem to be solved by this invention be provide for above-mentioned prior art problem a kind of design ingenious, resistance is little and a kind of railroad operated steadily.
The present invention solves the problems of the technologies described above adopted technological scheme: this railroad, include slide block, described slide block can be placed on suitable guide rail slidably, it is characterized in that: described guide rail is rectangular strip, axially the chute run through at two ends is arranged with respectively at four Middle face of this rectangular strip, the end face orthographic projection of described guide rail is the rectangle that four Middle face have breach, axially the through rectangular cavity suitable with rectangular strip in two ends is provided with in described slide block, and roller is convexly equipped with respectively on the four sides inwall of rectangular cavity, when described slide block set inserts on guide rail, described slide block rollably can be placed in corresponding chute respectively from the four limit rollers that inwall protrudes.
As improvement, every face inwall of described rectangular cavity is provided with two rollers, these two rollers are that time interval is arranged on straight line.
As improvement, on the inwall of described rectangular cavity, the concrete structure of projection roller is: described slide block four sides is respectively arranged with roller groove and axle bed groove, described roller stretches into chute in rectangular cavity with corresponding and can rollably fit in together, and described roller is embedded in corresponding axle bed groove by central shaft, is respectively arranged with cover plate central shaft and slide block are fixed together in the outside being positioned at axle bed groove.
As improvement, on the inwall of described rectangular cavity, the concrete structure of projection roller is: described slide block four sides is respectively arranged with cavity block, suitable module is plugged with in described cavity block, described roller can be arranged in module rotationally, when described module is inserted in the cavity block of slide block, the inwall that described roller stretches into rectangular cavity can rollably fit in together with corresponding chute, and described module is fixed together by fastening piece and slide block.
As improvement, described fastening piece can be preferably screw or bolt.
As improvement, described roller can be preferably rolling bearing; The outer circumferential face of described roller is arc surface, and described chute is the crown face groove suitable with the outer circumferential face of roller.
Compared with prior art, the present invention adopts described guide rail to be rectangular strip, axially the chute run through at two ends is arranged with respectively at four Middle face of this rectangular strip, the end face orthographic projection of described guide rail is the rectangle that four Middle face have breach, axially the through rectangular cavity suitable with rectangular strip in two ends is provided with in described slide block, and roller is convexly equipped with respectively on the four sides inwall of rectangular cavity, when described slide block set inserts on guide rail, be arranged in described slide block and rollably can be placed in corresponding chute respectively from the four limit rollers that inwall protrudes.The advantage of the design is: the four sides inwall of the rectangular cavity of slide block is convexly equipped with roller respectively, design ingenious, rational in infrastructure, not only increase force bearing point, also make force bearing point be distributed in the four sides of guide rail, make stressed more even, again because guide rail is wrapped in wherein by rectangular cavity, not only reduce slide block movement time frictional force, and the motion of slide block is become more steadily, more flexible.
