As shown in fig. 1 to 4, further, screw rods 301 are all provided at four corners at the top of the support plate 3, threaded holes 502 are all provided at four corners at the top of the moving plate 5, baffle plates 6 are all provided at two sides of the top of the moving plate 5, the baffle plates 6 at two sides are hollow structures, four screw rods 301 are engaged with the moving plate 5 through the four threaded holes 502, and the four screw rods 301 are respectively positioned inside the baffle plates 6 at two sides, so that the screw rods 301 can drive the moving plate 5 through connection with the threaded holes 502 after rotating, and meanwhile, the baffle plates 6 can provide protection for the screw rods 301, the adjusting rods 302 and other components, and the situation that a user mistakenly touches the screw rods 301 to cause a safety accident can be avoided.
When the lifting support is used on uneven terrain, the friction force between the lifting support and the ground can be increased through the buffer pad 101 and the anti-skid rubber pad, so that the lifting support can be kept stable, meanwhile, when the lifting support is used on inclined terrain, the lifting support is prevented from toppling by changing the angles of the supporting plate 3 and the connecting rods 102 through adjusting the heights of the jacks 2 on two sides, the gravity center of the lifting support is kept, after the lifting support is stabilized, a user can carry goods to climb the top of the moving plate 5, four motors 7 are started through the control panel, the motors 7 rotate and drive the screw rods 301 to rotate, the moving plate 5 is driven to be lifted along with the connection of the screw rods 301 and the threaded holes 502, the lifting support 4 provides partial supporting force for the moving plate 5 in the lifting process of the moving plate 5, the stability of the moving plate 5 is improved, simultaneously, the adjusting box 8 is driven to enable the adjusting block 804 to be extruded by the adjusting rod 302 so as to retract into the groove 801 and extrude the spring 803 until the spring 803 at the next thread pushes the adjusting block 804 out to clamp the adjusting block 804 with the adjusting rod 302 again, the purpose of automatic clamping is achieved, when the moving plate 5 is required to descend after the goods are delivered to a high place, a user dials the pull rod 806 to the side far away from the adjusting rod 302, along with the shrinkage of the adjusting block 804, the first clamping block 8011 approaches the first clamping groove 8041 and the second clamping block 805, when the first clamping block 8011 reaches the top of the first clamping groove 8041, the first clamping block 8011 descends and is clamped with the first clamping groove 8041 due to the action of gravity, the adjusting block 804 is far away from the adjusting rod 302, the motor 7 is reversely rotated through the control panel, the screw 301 drives the moving plate 5 to move downwards, in the process of the moving plate 5 upwards and downwards due to the action of the speed reducing disc 9, when the moving speed of the moving plate 5 is too slow, the rotating speed of the rotating shaft is too slow, the centrifugal force is smaller than the pulling force of the connecting spring 905, the centrifugal force is insufficient to stretch the connecting spring 905, at this time, the speed reducing block 904 is not contacted with the inner wall of the speed reducing disk 9, at this time, the resistance from the speed reducing disk 9, received by the adjusting rod 302, is smaller, the moving plate 5 can accelerate to move, when the moving speed of the moving plate 5 is too fast, the rotating speed of the rotating shaft is too fast, the centrifugal force is larger than the pulling force of the connecting spring 905, the centrifugal force stretches the connecting spring 905, at this time, the speed reducing block 904 is close to the inner wall of the speed reducing disk 9 along the sliding rail 903, when the friction ring is contacted with the friction plate 9043, the rotating speed of the speed reducing disk 9 is larger than the rotating speed of the connecting plate 902 due to the action of the speed reducer 901, because the two speed reducing blocks 904 with inconsistent rotation speed will generate friction with the inner wall of the speed reducing disc 9, the rotation speed of the speed reducing disc 9 is reduced, and therefore the moving speed of the moving plate 5 is reduced, when the lifting support descends to the bottom, a user dials the pull rod 806 to the side far away from the adjusting rod 302, along with further shrinkage of the adjusting block 804, the first clamping block 8011 will be matched with the second clamping groove 8051 and jacked up to change the angle, at the moment, the pull rod 806 is loosened, the spring 803 can rapidly push out the adjusting block 804 and be clamped with the adjusting rod 302, and separation of the first clamping block 8011 and the first clamping groove 8041 is completed.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and improvements can be made by those skilled in the art without departing from the spirit of the present invention, and these should also be considered as the scope of the present invention, which does not affect the effect of the implementation of the present invention and the utility of the patent.
