The following detailed description of the steps of the assembled elevator with quick assembly and disassembly as described herein is made with reference to fig. 1 to 6:

at the beginning, the first latch 32 is completely received in the first latch cavity 31, the second latch 36 is located at the upper limit position, the upper end of the second latch is located in the slot 34, the third latch 38 is located at the limit position far away from the symmetry center, the end of the third latch 38 far away from the symmetry center extends into the slot 34, and the slider 49 is located at the upper limit position.

When the lifting device works, the base 11 is placed at a proper position, so that the upper end of the assembled lifting device can lean against a required height position, the inserting rods 47 at the lower ends of a proper number of combined rods 14 are inserted into the inserting grooves 34 of the combined rods 14 adjacent to the lower sides, the inserting rod 47 at the lower end of the combined rod 14 at the lowest side is inserted into the inserting groove 34 of the rotating rod 13, the inserting rod 47 at the lower end of the rotating disc box 16 is inserted into the inserting groove 34 of the combined rod 14 at the highest side, after the inserting rod 47 is inserted into the inserting groove 34, the second clamping block 36 is inserted into the second clamping groove 51, at the moment, because the elastic forces of the second spring 44 and the third spring 39 are larger than that of the fourth spring 50, the second clamping block 36 continuously pushes the sliding block 49 to slide upwards, when the sliding block 49 slides upwards to the limit position, the inclined surface of the third clamping block 38 firstly abuts against the lower end surface of the sliding block 49 in the third clamping block cavity 37, and then one end, far away from, the other end of the steel cable 28 bypasses the upper end of the groove 61 from the left side of the supporting rod 15 and is fixedly connected to the upper end face of the connecting block 23 from the right side of the supporting rod 15, the motor 24 is started, the motor 24 drives the first belt wheel 58 to rotate, the second rotating shaft 26 and the winding drum 27 are driven to rotate through belt transmission, and then the winding drum 27 receives and releases the steel cable 28 to pull the sliding plate 21 to slide up and down, so that the effect of controlling the loading basket 22 to ascend and descend is achieved.

If the lifting speed exceeds the maximum speed due to an unexpected situation, when the first rotating shaft 17 rotates at a high speed, the first clamping block 32 slides towards the direction away from the axis against the pulling force of the first spring 33 under the action of centrifugal force, and one end of the first clamping block 32 away from the axis extends into the first clamping groove 29 to prevent the first rotating shaft 17 from rotating, so that the lifting is prevented from continuing.

When the elevator needs to be disassembled after being used, the elevator is carefully laid down, the pull ring 46 is pulled by force, the pull wire 45 in the rotating rod 13 pulls the first slide rod 43 in the rotating rod 13 to slide downwards, because the elasticity of the third spring 39 is greater than that of the fourth spring 50, the first slide rod 43 pulls the slide block 49 and the second fixture block 36 to slide downwards together, when the slide block 49 slides downwards, the other first slide rod 43 is pulled by the pull wire 45 connected with the slide block 49 to slide downwards, all the slide blocks 49 are pulled to slide downwards synchronously, when the slide block 49 slides downwards to the lower limit position, the first slide rod 43 pulls the third fixture block 38 to slide towards the direction close to the symmetrical center through the connecting rod 41, the third fixture block 38 is separated from the third fixture groove 52, all the second fixture blocks 36 slide downwards to be accommodated in the second fixture block cavities 35 by pulling the pull ring 46 continuously, when the second fixture block 36 slides downwards to the lower limit position, the end of the abutting rod 54 extending to the second fixture, and one end of the resisting rod 54 far from the symmetrical center pushes the second sliding rod 57 to slide upwards through the limiting rod 56, and the second sliding rod 57 pushes the inserting rod 47 upwards for a certain distance, so that the inserting rod can not be buckled automatically after the pull ring 46 is loosened.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
