[0026] Example:

[0027] See also Figure 1-5 A roller linear guide comprises a slide rail 1 and a slider 2. The slider 2 is slidably connected to the slide rail 1. Four sliding openings 3 are opened on the slider 2. Adjustment blocks 4 are slidably connected in the four sliding openings 3. The bottom ends of the four adjustment blocks 4 are detachably connected with rollers 5, and the four rollers 5 are all slidably connected to the slide rail 1. A distance adjustment mechanism is provided in the slider 2. The distance adjustment mechanism is used to adjust the positions of the four rollers 5 to adapt to slide rails 1 of different specifications.

[0028] In this embodiment, the slider 2 is slidably connected to the slide rail 1 through four rollers 5. The distance adjustment mechanism adjusts the positions of the four adjustment blocks 4 in the four sliding openings 3 to adjust the positions of the four rollers 5, so that the slider 2 can adapt to slide rails 1 of different sizes and adapt to double-track slide rails 1 of different installation positions.

[0029] Specifically, the distance adjustment mechanism includes a bidirectional threaded rod 61, two stroke nuts 62 and four connecting rods 63. The bidirectional threaded rod 61 is rotatably connected to the slider 2, and one end of the bidirectional threaded rod 61 passes through one side of the slider 2. The two stroke nuts 62 are both threadedly connected to the circumferential surface of the bidirectional threaded rod 61. The four connecting rods 63 are respectively hinged to the two stroke nuts 62 through hinge shafts, and one end of the four connecting rods 63 are respectively hinged to the four adjustment blocks 4 through hinge shafts.

[0030] In this embodiment, two threads in opposite directions are set on the circumferential surface of the bidirectional threaded rod 61, and two travel nuts 62 are respectively threadedly connected to the two opposite threads. By rotating the bidirectional threaded rod 61, the two travel nuts 62 are moved in opposite directions. Each travel nut 62 pushes the two adjustment blocks 4 to slide in the two sliding openings 3 through two connecting rods 63, thereby realizing the adjustment of the distance between the four rollers 5, so that the slider 2 can slide on the slide rails 1 of different sizes and double tracks.

[0031] Specifically, the top ends of the two travel nuts 62 are fixedly connected with a protrusion 7 , the top wall of the slider 2 is provided with a sliding groove 8 , and the two protrusions 7 are slidably connected in the sliding groove 8 .

[0032] In this embodiment, during the movement and adjustment process, the two travel nuts 62 respectively cause the two protrusions 7 to slide in the sliding grooves 8 to ensure the stability of the movement.

[0033] Specifically, bolts 9 are movably inserted between the four rollers 5 and the four adjustment blocks 4 respectively. The circumferential surfaces of the four bolts 9 are threadedly connected with locking nuts 10, and the four locking nuts 10 are respectively located on the upper sides of the four adjustment blocks 4.

[0034] In this embodiment, the four rollers 5 are mounted on the bottoms of the four adjustment blocks 4 by means of four bolts 9 and four locking nuts 10 , so that the four rollers 5 can be replaced according to actual use requirements.

[0035] Specifically, a plurality of fixing holes 11 are formed on the slide rail 1 , and a plurality of mounting holes 12 are formed on the slider 2 .

[0036] In this embodiment, the fixed slide rail 1 is installed through the fixing hole 11 , and the sliding device is installed on the slider 2 through the installation hole 12 .

[0037] Working principle: By rotating the bidirectional threaded rod 61, the two stroke nuts 62 move in opposite directions. Each stroke nut 62 pushes the two adjustment blocks 4 to slide in the two slides 3 through two connecting rods 63, thereby realizing the adjustment of the distance between the four rollers 5. The slider 2 is slidably connected to the slide rail 1 through the four rollers 5. The adjusted slider 2 can slide on slide rails 1 of different sizes and double tracks, thereby adapting to slide rails 1 of different sizes and double tracks.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
