Detailed Description

As shown in fig. 1 to 4, the speed reducer with adjustable height of the invention is positioned in a mounting groove of the ground, and comprises a mounting plate 1, a fixed box 2, a lifting rod 4, an adjusting component and a bearing component; wherein, the adjusting component drives the bearing component to move through the lifting rod 4.

The adjusting component comprises a motor 10, a rotating rod 12, two screw units with opposite rotation directions, a lifting plate 5, a connecting rod 15 and a connecting plate 16; the connecting rod 15 drives the connecting plate 16 and the lifting rod 4 to lift through the screw unit.

The bearing component comprises a tilting plate 6, a bearing plate 7 and a sliding rod 9, wherein the tilting plate 6 is connected with the sliding rod 9 through the bearing plate 7.

The both sides of mounting panel 1 are the slope setting, and fixed case 2 is located the lower extreme of mounting panel 1. The opening 3 has been seted up on the mounting panel 1, is connected with a plurality of lifter 4 through adjusting part in the fixed case 2, and lifter 4 passes fixed case 2, and slides in fixed case 2.

The upper end fixedly connected with lifter 4 lifter plate 5, the opening 3 department of mounting panel articulates there is hang plate 6, and the other end of two hang plates 6 all articulates there is loading board 7. One end of the bearing plate 7 close to the lifting plate 5 is provided with a plurality of sliding rod grooves 8 which are uniformly distributed at equal intervals. A sliding rod 9 is connected in the sliding rod groove 8 in a sliding mode, and one end, far away from the bottom of the sliding rod groove 8, of the sliding rod 9 penetrates through the notch of the sliding rod groove 8 and extends outwards to be connected with the lifting plate 5.

The adjusting component comprises a driving motor 11 and two fixing plates 10, and the fixing plates 10 and the driving motor 11 are fixedly connected to the bottom of the fixing box 2. A rotating rod 12 is rotatably connected between the two fixing plates 10 through two first bearings, the output end of the driving motor 11 is fixedly connected to one end of the rotating rod 12, two symmetrically arranged screw rods 13 are fixedly sleeved on the rotating rod 12, and the threads on the two screw rods 13 are oppositely arranged.

The screw 13 is sleeved with a threaded sleeve 14, and the threaded sleeve 14 is in threaded connection with the screw 13. Threaded sleeve 14's upper end articulates there is connecting rod 15, and two connecting rod 15's upper end all articulates with connecting plate 16, and the equal fixed connection of lower extreme at connecting plate 16's upper end of lifter 4.
