[0027] Referring to Figures 1-10 As shown in the figure, a lifting structure includes a fixed column 1 and a movable column 2 in the fixed column 1, and further includes a fluid power lifting device 3 arranged in the movable column 2, the movable column 2 is used to control one-time pressing of the fluid power lifting device 3, and a pressing plate 4 arranged on the fluid power lifting device 3 and movable on the movable column 2 is used to control two-time pressing of the fluid power lifting device 3.

[0028] The fluid power lifting device 3 can be a compression source such as hydraulic pressure or pneumatic pressure.

[0029] Among them, as Figure 2As shown, specifically, the fluid power lifting device 3 includes a main body 31 and a shaft 32 arranged on the main body 31, since the movable column 2 moves in the length direction of the fixed column 1, one end of the main body 31 away from the shaft 32 is fixed at the inner top position of the movable column 2, and one end of the shaft 32 away from the main body 31 abuts against the inner bottom of the fixed column 1 under the action of the compression source in the main body 31, in the initial state, the movable column 2 is stretched to the farthest distance on the fixed column 1 under the action of the fluid power lifting device 3.

[0030] In order to limit the main body 31, a cover 5 is arranged at the top of the movable column 2, the movable column 2 is tubular, the cover 5 includes a body 51 and a guide plate 52 arranged below the body 51, the body 51 covers the top surface of the movable column 2, and the guide plate 52 is inserted into the movable column 2, a screw is arranged at the side of the movable column 2 and screwed into the guide plate 52 after penetrating through the movable column 2, so as to fix the cover 5 on the movable column 2, when pressed once, the movable column 2 is pressed downward, the shaft 32 of the fluid power lifting device 3 is compressed into the main body 31, the extended part of the shaft 32 is shortened, and the overlapping area of the movable column 2 and the fixed column 1 is increased, a structure (self-locking gas spring) for locking when compressed to a certain extent is arranged in the fluid power lifting device 3, and unilateral locking does not occur when pressed in the middle, and the fluid power lifting device 3 on the unpressed side may not be locked when pressed on one side.

[0031] Specifically, movable grooves 521 are arranged at corresponding positions on the two guide plates 52, the main body 31 always has an upward force under the action of the fluid power lifting device 3, in order to limit the main body 31, a through hole is arranged at the top of the main body 31, and a fixed rod 6 is arranged in the through hole, the top end of the main body 31 is inserted into the spacing between the two guide plates 52, and the two ends of the fixed rod 6 are respectively embedded into the left and right movable grooves 521, under stress, the fixed rod 6 is in an abutting state in the movable grooves 521, and a through groove 511 with a width consistent with the spacing of the two guide plates 52 is arranged on the body 51, and the pressing plate 4 is arranged on the through groove 511.

[0032] It is necessary to ensure that a threaded column 321 is arranged on the lower part of the shaft 32, and a joint 7 with a threaded hole is arranged on the threaded column 321, the joint 7 only contacts the inner bottom plate of the fixed column 1, and it is tested that if the joint 7 is limited, the shaft 32 will be deformed due to shaking when pressed.

[0033] Specifically, the fixed rod 6 is up and down movable in the active slot 521, which is a waist circle, and the upper and lower ends are respectively the pressing end 5212 and the moving end 5211. In the initial state, the fixed rod 6 is always pressed against the pressing end 5212 under the action of the fluid power lifting device 3. When pressing once, the force is applied to the active column 2 and the cover 5, and then the fluid power lifting device 3 is pressed.

[0034] Specifically, the pressing plate 4 includes a pressing part 41 and a moving part 42, which is generally T-shaped. The cross-sectional area of the pressing part 41 is much larger than that of the moving part 42. The moving part 42 is inserted into the through slot 511 on the cover 5. In order to ensure that the pressing plate 4 can directly control the fluid power lifting device 3, the pressing plate 4 needs to be connected with the fluid power lifting device 3. Specifically, a socket 421 is arranged on the lower bottom surface of the moving part 42 to ensure that the top end of the main body 31 can be inserted into the socket 421. A through insertion hole is arranged at the bottom position of the moving part 42 and in the area of the socket 421. The two ends of the fixed rod 6 pass through the two insertion holes respectively. When the pressing plate 4 is pressed alone, the pressing plate 4 acts on the main body 31, and the fixed rod 6 moves from the pressing end 5212 of the active slot 521 to the moving end 5211.

[0035] Further, although the fluid power lifting device 3 is provided with a locking structure, due to the outdoor installation environment, in order to further prevent the unlocking of the active column 2, a locking piece 8 is arranged on the fixed column 1. The locking piece 8 is a conventional elastic buckle type pressing unlocking or locking device. A locking rod 81 is arranged on the locking piece 8 to the inside of the fixed column 1. A lock hole 9 is arranged on the top of the active column 2. In order to ensure a certain locking tolerance, the lock hole 9 is a waist circle. When the active column 2 is pressed to a certain distance in the fixed column 1, it is first locked by the locking mechanism in the fluid power lifting device 3, and then the locking rod 81 on the locking piece 8 is pressed, and the locking rod 81 further protrudes into the lock hole 9 on the active column 2 to be locked again.

[0036] The lifting structure is applied to the guardrail, the guardrail comprises the fixed column 1, the movable column 2 and the fluid power lifting device 3, and the fixed column 1 and the movable column 2 are assembled into two groups, and the one-side opening slot 10 is arranged on the fixed column 1 and the movable column 2, the both ends of the baffle 11 are inserted into the bottom of the slot 10, when the baffle 11 between the movable columns 2 is pressed, the movable column 2 can be controlled to move on the fixed column 1 and be in the locked or unlocked state by the fluid power lifting device 3.

[0037] The working process of the present application: in the initial state, the movable column 2 is in the completely unlocked state on the fixed column 1, and the overlapping area of the two is minimum, when the baffle 11 is pressed, the movable column 2 moves downwards in the fixed column 1 and reaches the locked position, if the unilateral locking occurs at this time, the pressing plate 4 on the movable column 2 of the unlocked side is pressed, the pressing plate 4 directly controls and presses the main body 31, so that the fluid power lifting device 3 of the unlocked side also reaches the locked state.

[0038] So far, various embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described.
