Detailed Description

The structure and use of the present invention will now be further described with reference to the accompanying drawings. As shown in fig. 1-4, the linear guide rail slider comprises a guide rail 1 and a slider 2, a plastic bearing 5 with an opening at one side is arranged in an opening at one side of the slider, the opening of the slider corresponds to the opening of the plastic bearing, the plastic bearing is sleeved in guide shafts fixed at two sides of the guide rail through the end part of the guide rail, a strip-shaped ventilation and heat dissipation groove 501 is arranged in the inner diameter of the plastic bearing at the buckling position of the slider and the plastic bearing, the opening of the slider is positioned at an inner side end angle, the inner side height of the opening of the slider is lower than the bottom height of the opening, the guide shafts of the guide rail are symmetrically arranged at two sides of the guide rail in a tilting. The specific structure is as follows: when the plastic bearing is connected with the buckling groove 201 of the sliding block into a whole through the bulge 502 of the outer diameter, the bulge of the plastic bearing is arranged at equal intervals, the middle bulge is provided with a raised positioning column, the raised positioning column is inserted into the positioning hole in the buckling groove of the sliding block, and the end angle of the outer side of the buckling groove of the sliding block is provided with a vertical insertion groove. The sliding blocks are symmetrically arranged at four end corners at the bottom of the platform 3 through bolts 4 in pairs, and mounting holes are respectively formed in the positions of the bolts of the platform and the sliding blocks. As shown in fig. 5, or four sliders are connected into a whole to form an integral slider; as shown in fig. 6, the guide shaft of the guide rail is circular, triangular, rectangular or polygonal, and the inner diameter shape of the plastic bearing is correspondingly sleeved with the shape of the guide shaft of the guide rail. The sliding block and the guide rail are made of alloy materials, the guide rail is made of reinforced aluminum alloy and is oxidized by anode hardness to replace a steel material, the problem that the steel material is easy to corrode at high temperature, low temperature, water and corrosive substances is solved, and a guide shaft of the guide rail is circular.
