DETAILED DESCRIPTION
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] See Figure 1 —— Figure 4 The present invention discloses a high-rigidity lifting platform, comprising: a lower fixed plate 1, on which an outer guide rail 5 is fixedly mounted. A hole is opened in the middle of the lower fixed plate 1, and a motor 2 is mounted below the lower fixed plate 1. The driving shaft of the motor 2 passes through the lower fixed plate 1 and is located in the outer guide rail 5. The motor 2 drives a lead screw 3, on which a lead screw nut 4 is mounted, and on which a rising guide rail 6 is sleeved. A rising plate 7 is mounted on the top of the rising guide rail 6. When the lead screw nut 4 moves, the rising guide rail 6 is driven to move and rise.
[0022] The outer guide rail 5 of the present invention is in a square frame shape, with a square through hole inside. The four corners of the outer guide rail 5 cooperate with the rising guide rail 6. The rising guide rail 6 is square, and the four vertical edges of the rising guide rail 6 are respectively equipped with a first needle roller cage 9, a second needle roller cage 12, a third needle roller cage 15, and a fourth needle roller cage 16. Each needle roller cage is L-shaped, and each surface thereof is provided with a plurality of limiting holes 17, and a needle roller 10 is horizontally arranged in each limiting hole 17. The needle roller 10 is in close contact with the side of the rising guide rail 6, so that the rising guide rail 6 can be lifted and lowered more smoothly.
[0023] Two side surfaces of the square through hole of the outer guide rail 5 of the present invention are respectively formed with two vertical mounting grooves, in which the first adjustment guide rail 8, the second adjustment guide rail 11, the third adjustment guide rail 13, and the fourth adjustment guide rail 14 are respectively fixedly installed. The first adjustment guide rail 8 corresponds to a side surface of the first needle roller retainer 9, the second adjustment guide rail 11 and the third adjustment guide rail 13 respectively correspond to a side surface of the second needle roller retainer 12, and the fourth adjustment guide rail 14 corresponds to a side surface of the third needle roller retainer 15.
[0024] The outer guide rail 5 of the present invention is provided with a locking screw hole, which passes through the mounting groove of the outer guide rail 5. The first adjustment guide rail 8, the second adjustment guide rail 11, the third adjustment guide rail 13, and the fourth adjustment guide rail 14 are provided with locking screw holes, and the locking screws 18 fix the first adjustment guide rail 8, the second adjustment guide rail 11, the third adjustment guide rail 13, and the fourth adjustment guide rail 14.
[0025] The outer guide rail 5 of the present invention is provided with an adjustment screw hole, which passes through the installation groove of the outer guide rail 5. The adjustment screw 19 passes through the adjustment screw hole and movably abuts against the surfaces of the first adjustment guide rail 8, the second adjustment guide rail 11, the third adjustment guide rail 13, and the fourth adjustment guide rail 14. By adjusting each adjustment guide rail through the adjustment screw 19, the installation and adjustment of the rising guide rail 6 is more convenient.
[0026] The present invention uses a plurality of needle rollers 10 on the first needle roller retainer 9, the second needle roller retainer 12, the third needle roller retainer 15, and the fourth needle roller retainer 16 to ensure that the rising guide rail 6 can remain stable when it is raised or lowered, and the first adjustment guide rail 8, the second adjustment guide rail 11, the third adjustment guide rail 13, and the fourth adjustment guide rail 14 can increase the coordination of the rising guide rail 6 and maintain a high rigidity so that each upper guide rail 6 can obtain a greater bearing capacity.
[0027] Of course, the embodiments described above are only preferred examples of the present invention and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
