Description

Technical Field

[0001] The present invention belongs to the field of sliding guide rail technology, and specifically relates to a guide rail that can be quickly disassembled and assembled. Background Technology

[0002] Sliding guides have a wide range of applications in daily life. Existing sliding guides usually have a guide bushing inside the guide rail, which contacts the base. The friction between the guide rail and the base is reduced by installing ball bearings inside the guide bushing or by using low-friction materials to make the guide bushing.

[0003] In actual production, various components are usually installed on the support base. However, in daily use, especially on personal work platforms, the processing tools are usually fixed on the guide rail for easy movement. This makes it convenient to move the tools during use. However, the processing tools are usually fixed on the slider of the guide rail with bolts, which makes disassembly and assembly inconvenient when the processing tools need to be removed. There are areas for improvement in the existing technology. Summary of the Invention

Multiple first locking blocks are fixedly mounted on the inner wall of the fixed ring, and the multiple first locking blocks are evenly distributed around the center of the fixed ring on the inner wall of the fixed ring. The first locking blocks gradually tilt downwards along the inner wall of the fixed ring. A tool for fixed connection to an external processing tool is provided on the fixed ring. The connecting plate has a limiting ring fixedly installed on its lower end surface, which is inserted into a fixed ring. The outer wall of the limiting ring abuts against the inner wall of the first locking block. Multiple second locking blocks that cooperate with the first locking block are fixedly installed on the outer wall of the limiting ring. The second locking blocks are located directly below the first locking blocks, and the upper end of the second locking block has an inclined surface that cooperates with the lower end surface of the first locking block. The inclined surface abuts against the lower end surface of the first locking block, and the length of the second locking block is less than the distance between two adjacent first locking blocks. A driving mechanism for driving the rotating plate to rotate counterclockwise is provided between the rotating plate and the second fixed plate. A limiting mechanism for limiting the rotation range of the rotating plate is provided on the rotating plate. A positioning mechanism for installing the connecting plate is provided on the annular plate.

[0006] Preferably, the driving mechanism includes a first annular groove formed on the lower end face of the rotating plate, the first annular groove surrounding the outer periphery of the aforementioned rotating shaft, and a planar spiral spring for driving the rotating plate to rotate counterclockwise is disposed inside the first annular groove, one end of the planar spiral spring being fixedly disposed on the rotating shaft, and the other end being fixedly disposed on the outer wall of the first annular groove.

[0007] Preferably, the limiting mechanism includes multiple arc-shaped grooves formed on the rotating plate and extending vertically through the rotating plate. The multiple arc-shaped grooves are evenly distributed on the rotating plate around the center of the rotating plate and are located in the same circle. The upper end of the support base is fixedly provided with multiple blocks inserted into the arc-shaped grooves, and the blocks are located at one end of the arc-shaped grooves.

[0024] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings: Figure 1-8As shown, a quick-assembly and disassembly guide rail includes a rail 1 and a support base 2 movably mounted on the guide rail. An annular plate 44 is fixedly mounted on the support base 2. A rotating shaft 45 is fixedly mounted at the center of the annular plate 44. A rotating plate 46 is rotatably mounted between the annular plate 44 and the rotating shaft 45. The rotating plate 46 is rotatably mounted on the rotating shaft 45. A fixed ring 47 extending upwards is fixedly mounted on the outer periphery of the rotating plate 46. The lower end of the fixed ring 47 is fixedly mounted on the outer wall of the rotating plate 46. Multiple first locking blocks 48 are fixedly mounted on the inner wall of the fixed ring 47. The multiple first locking blocks 48 are evenly distributed around the center of the fixed ring 47 on the inner wall of the fixed ring 47. The first locking blocks 48 gradually tilt downwards along the inner wall of the fixed ring 47. A connecting plate 49 is provided on the fixed ring 47 for fixed connection with an external processing tool. The lower end face of the connecting plate 49... A limiting ring 50 is fixedly installed inside the fixing ring 47. The outer wall of the limiting ring 50 abuts against the inner wall of the first locking block 48. A plurality of second locking blocks 51 that cooperate with the first locking block 48 are fixedly installed on the outer wall of the limiting ring 50. The second locking blocks 51 are located directly below the first locking block 48, and the upper end of the second locking block 51 has an inclined surface 52 that cooperates with the lower end surface of the first locking block 48. The inclined surface 52 abuts against the lower end surface of the first locking block 48, and the length of the second locking block 51 is less than the distance between two adjacent first locking blocks 48. A driving mechanism 54 for driving the rotating plate 46 to rotate counterclockwise is provided between the rotating plate 46 and the second fixing plate. A limiting mechanism 54 for limiting the rotation range of the rotating plate 46 is provided on the rotating plate 46. A positioning mechanism 55 for installing the connecting plate 49 is provided on the annular plate 44.

[0025] In use, by connecting the connecting plate 49 to an external processing tool, and by inserting the limiting ring 50 on the connecting plate 49 into the fixing ring 47, the second locking block 51 on the limiting ring 50 is inserted into the fixing ring 47 along the gap between two adjacent first locking blocks 48 on the fixing ring 47. When the fixing ring 47 rotates, the first locking block 48 on the inner wall of the fixing ring 47 rotates to above the second locking block 51 on the limiting ring 50. Through the inclined first locking block 48 and the inclined surface 52 on the second locking block 51, the first locking block 48 drives the second locking block 51 to move towards the rotating plate 46, and always presses the connecting plate 49 against the support base 2. This allows for convenient installation and fixing of the connecting plate 49. When the connecting plate 49 is removed, by rotating the fixing ring 47 so that the first locking block 48 on the fixing ring 47 is located in the gap between two adjacent second locking blocks 51 on the limiting ring 50, the connecting plate 49 can be directly removed, allowing for quick assembly and disassembly of the connecting plate 49.

[0026] The driving mechanism 54 includes a first annular groove 56 formed on the lower end face of the rotating plate 46, which surrounds the outer periphery of the rotating shaft 45. A planar spiral spring 57 is disposed inside the first annular groove 56, driving the rotating plate 46 to rotate counterclockwise. One end of the planar spiral spring 57 is fixedly mounted on the rotating shaft 45, and the other end is fixedly mounted on the outer wall of the first annular groove 56. The planar spiral spring 57 continuously drives the rotating plate 46 and the fixed ring 47 to rotate counterclockwise. After the fixed ring 47 is released, it remains locked under the drive of the planar spiral spring 57, ensuring reliable locking.

[0027] The limiting mechanism 54 includes multiple arc-shaped grooves 58 formed on the rotating plate 46 and extending vertically through it. These arc-shaped grooves 58 are evenly distributed around the center of the rotating plate 46 and are located within the same circle. Multiple stops 59 are fixedly installed at the upper end of the support base 2, inserted into the arc-shaped grooves 58. Each stop 59 is located at one end within the arc-shaped groove. Three arc-shaped grooves 58 and three stops 59 are provided, with each corresponding to one stop. The rotating plate 46's rotation range is limited by the cooperating stops 59 and arc-shaped grooves 58. Driving the rotating plate 46 to rotate causes another latch of the arc-shaped groove 58 to engage with the stop 59, thus moving the first latch 48 on the fixing ring 47 into the gap between two adjacent second latches 51 on the limiting ring 50. This allows for the removal of the connecting plate 49 in one operation, making it convenient to use.

[0028] The positioning mechanism 55 includes a positioning post 60 fixedly mounted on the annular plate 44. A positioning plate 61 for engaging with the upper end of the positioning post 60 is fixedly mounted on the outer periphery of the connecting plate 49. A positioning groove 62 is formed on the positioning post 60. A positioning block 63 for engaging with the positioning groove 62 is fixedly mounted on the end face of the positioning plate 61 facing the positioning post 60. A pressure ring 64 is fixedly mounted on the lower end face of the connecting plate 49. The diameter of the pressure ring 64 is the same as the diameter of the circle formed by the plurality of arc grooves 58. The pressure ring 64 presses against the arc grooves 58. A limiting groove 65 is formed at the upper end of the stop block 59. A plurality of limiting blocks 66 for inserting into the limiting groove 65 are fixedly mounted on the lower end face of the pressure ring 64. When fastening the connecting plate 49, the connecting plate 49 can be lowered by inserting the positioning block 63 on the positioning plate 61 into the positioning groove 62 on the positioning post 60. At this time, the limiting block 66 on the pressure ring 64 on the connecting plate 49 is located directly above the limiting groove 65 on the stop block 59, which can accurately insert the limiting block 66 into the limiting groove 65 to fix the connecting plate 49 and prevent the connecting plate 49 from rotating during the rotation of the fixing ring 47.

[0029] A second annular groove 67 is formed on the inner wall of the annular plate 44, and a protruding edge 68 is fixedly provided on the outer wall of the fixing ring 47 for engaging within the second annular groove 67. The second annular groove 67 and the protruding edge 68 ensure that the fixing ring 47 is always engaged within the annular plate 44 and rotates within it. Multiple push buttons 69 are fixedly provided on the outer circumference of the fixing ring 47, and these push buttons 69 are evenly distributed on the outer wall of the fixing ring 47. The push buttons 69 facilitate the rotation of the fixing ring 47. Multiple anti-slip pads 70 are fixedly provided on the upper surface of the connecting plate 49, and these anti-slip pads 70 are evenly distributed around the center of the connecting plate 49. This prevents external processing tools from slipping when mounted on the connecting plate 49, making operation more stable.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
