Fifth, detailed description of the invention

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations where mutually exclusive features or steps are mutually exclusive.

As shown in figure 1, the novel roller guide rail is composed of a moving assembly (2) and a rail (1). The moving assembly (2) freely moves along the axial direction of the track (1). A connecting hole is reserved on the upper plane of the sliding connecting plate (2.1) in the moving assembly (2), bearing equipment, a cabinet body and the like can be installed, and double-track or multi-track combination can be used in a matched mode.

As shown in fig. 2, the track (1) is composed of a track profile (1.1), a hard strip steel (1.2) and a hard surface optical axis (1.3). The track profile (1.1) is a metal guide rail which is manufactured by one-step molding of automatic profile production equipment, and the surface of the track profile is subjected to anticorrosion and antirust treatment; the hard strip steel (1.2) is strip-shaped, the depth of a horizontal groove of the rail section (1.1) is equal to the thickness of the hard strip steel (1.2), the width of the horizontal groove is suitable for assembly, and the horizontal groove is fixed in the horizontal groove of the rail section (1.1) in a bonding or mechanical fastener mode; hard face optical axis (1.3) assemble in the arc recess of track section bar (1.1) after the length cutting according to needs, the arc recess of track section bar (1.1) is greater than 180 intrados for the contained angle, consequently need not extra fixed mode alright block hard face optical axis (1.3) arc recess and can not drop by oneself.

As shown in fig. 3, the moving assembly (2) is formed by fixing a reference roller (2.4) and a guide roller (2.5) at two ends of a sliding connecting plate (2.1) through a roller mounting plate (2.2), a reference roller shaft (2.3), a guide roller shaft (2.6), a guide mounting plate (2.7), a rolling gap adjusting member (2.8) and a dustproof scraper (2.9).

The outer surface of the guide roller (2.6) is an inwards concave arc surface, and the radian size of the outwards convex arc surface is consistent with that of the hard surface optical axis (1.3), so that the guide roller is matched with the hard surface optical axis to limit the movement of the movable assembly (2) along the axis of the track (1). The roller mounting plate (2.2) is fixed on the sliding connecting plate (2.1), the reference roller shaft (2.3) penetrates through the roller mounting plate (2.2) and the guide mounting plate (2.7), and the reference rollers (2.4) are assembled on two sides; the guide roller shaft (2.6) penetrates through the guide mounting plate (2.7) and is equipped with guide rollers (2.6) on both sides.

As shown in figure 4, the reference roller (2.4) is in contact with the exposed plane of the hard strip steel (1.2) embedded in the track section bar (1.1) and can freely roll, and the axis of the reference roller shaft (2.3) is in a fixed position relative to the sliding connecting plate (2.1). The bearing capacity of the reference roller (2.4) is transferred to the position of the bearing vertical beam of the track section bar (1.1) along the normal direction of the hard strip steel (1.2), and the bearing capacity of the moving assembly (2) is ensured.

As shown in fig. 5, the rolling gap adjusting member (2.8) is a threaded component, the axis of the guide roller shaft (2.6) can rotate around the axis of the reference roller shaft (2.3) within a certain angle, and the guide roller shaft (2.6) is driven to rotate around the axis of the reference roller shaft (2.3) by the lever action of the force applied at one side of the guide mounting plate (2.7), so as to drive the guide roller (2.6) to move, thereby adjusting the size of the fit gap between the guide roller (2.6) and the hard surface optical axis (2.6), and meeting the requirement of the fit gap adjustment during the relative displacement between the moving assembly (2) and the track (1).

As shown in the figures 1, 5 and 6, the dust removing plate (2.9) is installed on the outermost side of two ends of the sliding connecting plate (2.1) and is made of high-molecular wear-resistant materials, a mechanical fastener penetrates through the dust removing plate (2.9) and then is locked on the roller mounting plate (2.2), a spring (2.10) in a compression state is arranged below the fastener, the working plane of the dust removing plate (2.9) is attached to the exposed plane of the hard steel strip (1.2), and when the moving assembly (2) moves, impurities such as dust, granular sand, grease scrap iron and the like are removed, so that the impurities are prevented from entering the contact surface of the reference roller (2.4) and the hard steel strip (1.2), and the moving stability of the moving assembly (2) is damaged. When the working plane of the dust removing plate (2.9) is abraded, the fastener is a fixing piece and cannot move, so that the spring (2.10) releases acting force on the dust removing plate (2.9) to force the dust removing plate to move towards the direction of the hard steel strip (1.2), a gap between the working plane of the dust removing plate (2.9) and the exposed plane of the hard steel strip (1.2) caused by abrasion is eliminated, and the two working planes are always in a joint state.

The embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments described above, and it will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made herein without departing from the spirit and scope of the invention.
