[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0018] like Figures 1 to 4As shown, a novel linear guide includes a guide rail seat 1, a slide rail seat 2 and a slide rail body 3, wherein the left and right sides of the guide rail seat 1 are provided with slide grooves 4, and an adjustment plate 5 is slidably connected in the slide grooves 4, a mounting seat 6 is provided on the front side of the guide rail seat 1, and an adjustment rod 7 is rotatably connected to the front side of the mounting seat 6, and first screws 8 are rotatably connected to the left and right sides of the mounting seat 6, and two of the first screws 8 are respectively meshed with the adjustment rod 7 through a bevel gear 9, and the two first screws 8 are correspondingly threadedly connected to the two adjustment plates 5, Two sliding rods 10 are provided on the rear side of the guide rail seat 1, and the two sliding rods 10 are slidably connected to the two adjustment plates 5 respectively.

[0019] The working principle of the novel linear guide described in the utility model is realized by the cooperation between the guide rail seat 1, the slide rail seat 2 and the slide rail body 3. Figures 1 to 4 As shown, when adjusting the position of the adjusting plate 5 in the slide slot 4, the adjusting rod 7 on the mounting seat 6 is rotated, and the adjusting rod 7 and the two first screw rods 8 are linked through the bevel gear 9 to make the two first screw rods 8 rotate, as shown in FIG. Figure 1 As shown, the adjusting rod 7 rotates in the clockwise direction, and the first screw rod 8 located on the right side of the mounting seat 6 rotates toward the front side of the mounting seat 6, that is, Figure 2 The first screw rod 8 shown on the right side of the mounting seat 6 rotates in the clockwise direction, and the other first screw rod 8 rotates in the opposite direction to the first screw rod 8 located on the right side of the mounting seat 6. In this way, the rotation directions of the two first screw rods 8 are opposite, which can drive the adjusting plate 5 to move toward or away from each other, thereby adjusting the depth of the slide groove 4. When adjusting the installation height of the slide rail seat 2, the second screw rod 11 on the guide rail seat 1 is rotated. The second screw rod 11 is threadedly connected to the slide rail seat 2 and can drive the slide rail seat 2 to move up and down, thereby adjusting the installation height of the slide rail seat 2. When adjusting the spacing between the two slide rail bodies 3, the adjusting gear 12 on the guide rail seat 1 is rotated. The adjusting gear 12 drives the two slide rail bodies 3 to move toward or away from each other through the rack 13, thereby adjusting the spacing between the two slide rail bodies 3. Compared with the traditional guide rail, the new linear guide rail can adjust the spacing between the two slide rail bodies 3, thereby meeting the use requirements of sliders of different specifications and improving the applicability of the slide rail body 3.

[0020] Specifically, a support seat is provided at the rear side of the guide rail seat 1, one end of the two slide bars 10 is connected to the left and right sides of the support seat respectively, a slide plate 14 is provided at one end of the adjustment plate 5, and a threaded plate 15 is provided at the other end of the adjustment plate 5, and the two adjustment plates 5 are threadedly connected to the two first screw rods 8 via the threaded plate 15, and the two adjustment plates 5 are slidably connected to the two slide bars 10 via the slide plate 14. Figures 1 to 3 As shown, the first screw rod 8 rotates and causes the threaded plate 15 to move along the first screw rod 8, the adjusting plate 5 moves along the slide groove 4 with the threaded plate 15, and the adjusting plate 5 drives the slide plate 14 to move along the slide rod 10, which has a guiding and supporting function, wherein the mounting seat 6 is a concave seat body, one end of the adjusting rod 7 and one end of the two first screw rods 8 extend into the mounting seat 6 and mesh through the bevel gear 9, and the other end of the adjusting rod 7 is provided with a handle, wherein the back-facing ends of the two first screw rods 8 are flush with the left and right sides of the guide rail seat 1, and the back-facing ends of the two first screw rods 8 are provided with a limit ring 16, as shown in FIG. Figures 1 to 4 As shown, the handle is convenient for the staff to rotate the adjusting rod 7, and the limiting ring 16 on the first screw rod 8 can limit the threaded plate 15 to prevent the threaded plate 15 from falling off from the first screw rod 8.

[0021] Furthermore, the front and rear sides of the guide rail seat 1 are provided with sliding grooves 17, and the tops of the front and rear sides of the guide rail seat 2 are provided with linkage plates 18. The two linkage plates 18 of the guide rail seat 2 are slidably connected with the two sliding grooves 17, and the linkage plate 18 located on the front side of the guide rail seat 2 is threadedly connected with the second screw 11. Figures 1 to 4 As shown, the second screw rod 11 rotates to drive the linkage plate 18 to move up and down along the sliding groove 17, thereby causing the slide rail seat 2 to move up and down in the guide rail seat 1 and adjusting the installation height of the slide rail seat 2 in the guide rail seat 1.

[0022] Furthermore, the middle part of the slide rail seat 2 is provided with a limit block 19 above and below the adjusting gear 12, and the racks 13 of the two slide rail bodies 3 are correspondingly arranged at a distance between the two limit blocks 19 and the adjusting gear 12, and the two racks 13 are arranged facing each other, such as Figure 3 As shown, the rack 13 moves between the limit block 19 and the adjusting gear 12, and has a limit guiding function. If the adjusting gear 12 rotates in the clockwise direction, the rack 13 located above the adjusting gear 12 moves to the right, and the rack 13 located below the adjusting gear 12 moves to the left, thereby causing the two slide rail bodies 3 to move away from each other. If the adjusting gear 12 rotates in the counterclockwise direction, the two slide rail bodies 3 move toward each other, thereby adjusting the distance between the two slide rail bodies 3 to meet the use requirements of sliders of different specifications.
