[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] like Figure 1-4 As shown, in this embodiment, it includes an outer tube 1, a locking assembly 2, a damping rod 3 and an inner rod 4, the locking assembly 2 is fixedly arranged on the inner top of the outer tube 1, the damping rod 3 is fixedly connected to the bottom end of the outer tube 1, and the inner rod 4 is telescopically connected to the inside of the outer tube 1;

[0027] The locking assembly 2 includes a first connecting ring 31 and a second connecting ring 34; the first connecting ring 31 is fixedly connected to the inner top of the outer tube 1, and the outer part of the first connecting ring 31 is rotatably connected to the first buckle 32, and the upper end surface of the first buckle 32 is fixedly connected to the first spring 33; the second connecting ring 34 is fixedly connected to the inner top of the outer tube 1, and the outer part of the second connecting ring 34 is rotatably connected to the second buckle 35, and the upper end surface of the second buckle 35 is fixedly connected to the second spring 36.

[0028] In specific implementation, when the carousel is lifted or lowered too much, the spacing between the two outer cylinders 1 becomes smaller, thereby driving the two sets of locking assemblies 2 to move to the position of the inner rod 4 and the two sets of damping rods 3. Both ends of the inner rod 4 and the ends of the two sets of damping rods 3 are provided with card slots, and the two ends of the inner rod 4 push the two sets of second buckles 35, and the two sets of second buckles 35 rotate and engage the card slots. At the same time, the ends of the two sets of damping rods 3 respectively push the two sets of first buckles 32 to rotate, and the two sets of first buckles 32 rotate and engage the card slots of the two sets of damping rods 3, so that the inner rod 4, the two sets of damping rods 3 and the two outer cylinders 1 are fixed, so that they can be automatically locked, so that the carousel will no longer continue to move, avoiding damage caused by excessive lifting or lowering.

[0029] Furthermore, the first connecting ring 31 and the second connecting ring 34 are fixedly connected to the outer cylinder 1 through a plurality of connecting plates.

[0030] like Figure 2 As shown, further, a third spring 41 is sleeved on the outside of the inner rod 4; both ends of the inner rod 4 are telescopically connected in the two outer tubes 1 respectively.

[0031] In specific implementation, when the carousel moves up and down, it drives an outer cylinder 1 on the upper part to move up and down, thereby driving the inner rod 4 to perform telescopic buffering under the action of the spring, and at the same time drives the two groups of damping rods 3 to telescopically move in the relative outer cylinders 1 respectively.

[0032] like Figure 2-4 As shown, further, the two groups of damping rods 3 are plugged into each other and penetrate the slot 5 to extend into the interior of the outer tube 1.

[0033] During specific implementation, the two groups of damping rods 3 move relative to each other, and friction is used to provide damping between the two groups of damping rods 3 to prevent rebound. In addition, damping medium is poured into the two groups of damping rods 3 to enhance the damping effect. It should be noted that the positions of the two groups of damping rods 3 are different, and one group of damping rods 3 is rotated thirty degrees around the center so that the two groups of damping rods 3 can be plugged into each other.

[0034] like Figure 1 As shown, further, the outer ends of the two outer cylinders 1 are fixedly connected with a plurality of fixing rods 6 .

[0035] In specific implementation, the carousel and the base frame need to be fixedly connected via the fixing rod 6 on the outer cylinder 1 before operation.

[0036] Working principle: First, the carousel and the base frame are fixedly connected through the fixing rod 6 on the outer cylinder 1. When the carousel is lifted up and down, the upper outer cylinder 1 is driven to lift up and down, and then the inner rod 4 is driven to extend and retract under the action of the spring. At the same time, the two groups of damping rods 3 are driven to extend and retract in the relative outer cylinders 1 respectively, and the two groups of damping rods 3 move relative to each other. The two groups of damping rods 3 are damped by friction to prevent rebound. When the lifting range of the carousel is too large, the distance between the two outer cylinders 1 becomes smaller, which drives the two groups of locking components. 2 is moved to the position of the inner rod 4 and the two groups of damping rods 3. Both ends of the inner rod 4 and the ends of the two groups of damping rods 3 are provided with card slots. The two ends of the inner rod 4 push the two groups of second card buckles 35, and the two groups of second card buckles 35 rotate and engage the card slots. At the same time, the ends of the two groups of damping rods 3 respectively push the two groups of first card buckles 32 to rotate, and the two groups of first card buckles 32 rotate and engage the card slots of the two groups of damping rods 3. In this way, the inner rod 4, the two groups of damping rods 3 and the two outer cylinders 1 are fixed, and they can be automatically locked, so that the carousel will no longer continue to move, and damage caused by excessive lifting and lowering range can be avoided.
