[0028] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled persons in the art without creative labor belong to the scope of protection of the utility model.

[0029] Embodiment one

[0030] Referring to Figures 1-5 The utility model discloses a fence lifting structure, mainly used for bed lifting safety and operation convenience, of course, can also be used in other similar scenes, such as Figure 1 And Figure 2As shown, the fence lifting structure comprises oppositely arranged upper guardrail assembly 1 and lower guardrail assembly 2, and oppositely arranged first limiting rod 3 and second limiting rod 4. The two ends of the upper guardrail assembly 1 are respectively movably inserted into the first limiting rod 3 and the second limiting rod 4, so that the upper guardrail assembly 1 can move up and down along the length direction of the first limiting rod 3 and the second limiting rod 4 to approach or move away from the lower guardrail assembly 2. The two ends of the lower guardrail assembly 2 are respectively fixed on the first limiting rod 3 and the second limiting rod 4. The upper guardrail assembly 1 comprises a first branch pipe 11, the two ends of the first branch pipe 11 are respectively connected with end covers, a limiting cavity 112 is formed on the first branch pipe 11, and a handle cover 13 is slidably installed at the limiting cavity 112, so that the handle cover 13 can slide horizontally in the limiting cavity 112. The handle cover 13 is connected with a connecting rod 14, the connecting rod 14 is arranged in the cavity of the first branch pipe 11 and connected with a locking block 15. Specifically, the two ends of the connecting rod 14 are respectively fixed with the locking block 15 and the handle cover 13 through pins. The connecting rod 14 moves together by sliding the handle cover 13, so that the locking block 15 moves synchronously. A spring 16 is arranged between the locking block 15 and the end cover, and the elastic force between them makes the locking block 15 close to the connecting rod 14. The first limiting rod 3 penetrates the locking block 15 and forms a limiting hole. The number of limiting holes is selected according to design requirements. A limiting protrusion is formed on the locking block 15. The locking block 15 is driven by the elastic force or overcomes the elastic force to make the limiting protrusion cooperate with the limiting hole or separate from each other. In actual use, when the upper guardrail assembly 1 is lifted to the position of the limiting hole of the first limiting rod 3, the force of the spring 16 pushes the limiting protrusion on the locking block 15 to lock the upper guardrail assembly 1, so that the upper guardrail assembly 1 stops lifting. Conversely, when lifting adjustment is needed, the handle cover 13 is pushed to slide towards the first limiting rod 3, so as to drive the locking block 15 to approach the spring 16 and overcome the elastic force, so that the limiting protrusion on the locking block 15 is separated from the limiting hole. Thus, the upper guardrail assembly 1 can be adjusted up and down, such as lifting or pressing the upper guardrail assembly 1 with hands.

[0031] Embodiment two

[0032] Reference Figures 1-5 As shown in the technical scheme of embodiment one, a fence lifting structure, like Figure 2 and Figure 5 It can be seen that a limiting through hole is formed on the locking block 15, and the first limiting rod 3 is arranged in the limiting through hole. Since the locking block 15 needs to move horizontally, the size of the limiting through hole is larger than the outer diameter of the first limiting rod 3. In addition, the elastic force of the spring 16 drives the limiting protrusion to move towards the connecting rod 14, so that the limiting operation between the limiting protrusion and the limiting hole can be completed by elastic buckling. The elastic clamping or resetting structure design of the locking block 15 meets the single-handed use requirement and is convenient to operate.

[0033] Furthermore, the two ends of the first branch pipe 11 are respectively connected to a first end cover 17 and a second end cover 18. Specifically, the first end cover 17 and the second end cover 18 are respectively connected to the first branch pipe 11 through a first screw. The first end cover 17 contains a locking block 15 and is penetrated by the first limiting rod 3. The first end cover 17 and the first limiting rod 3 are transitionally matched, so that the first end cover 17 can slide smoothly along the length direction of the first limiting rod 3. In addition, the first branch pipe 11 is machined with a first guide hole 111 and a second guide hole 113 at both ends. The first guide hole 111 accommodates the first limiting rod 3. The first branch pipe 11 and the first limiting rod 3 are in a transitional fit, allowing the first branch pipe 11 to slide smoothly along the length of the first limiting rod 3. The second guide hole 113 is inserted into the second limiting rod 4, which is movably inserted into the second end cover 18. The first branch pipe 11 and the second end cover 18 are in a transitional fit with the second limiting rod 4, allowing both the first branch pipe 11 and the second end cover 18 to slide smoothly along the length of the second limiting rod 4. In addition, the locking block 15 and the handle cover 13 are fixed to each end of the connecting rod 14 by pins.

[0034] Example 3

[0035] Reference Figures 1-5 As shown, based on the technical solution of the above embodiment, a fence lifting structure is combined with Figures 1-4 It can be seen that the upper guardrail assembly 1 further includes a plurality of first vertical pipes 12 , which are fixed to the first branch pipe 11 , and the fixation of the two is generally achieved by welding, which will not be elaborated here.

[0036] Furthermore, the lower guardrail assembly 2 includes a second branch pipe 21 and a plurality of second vertical pipes 22 fixed to the second branch pipe 21. Each second vertical pipe 22 corresponds to a first vertical pipe 12 and is movably mounted. This allows each vertical pipe to function as a protective barrier when the spacing between the lower guardrail assembly 2 and the upper guardrail assembly 1 changes. Furthermore, the ends of the second branch pipe 21 are respectively fixed to a third end cap 23 and a fourth end cap 24 by second screws. The first limiting rod 3 is simultaneously fixed to one end of the second branch pipe 21 and the third end cap 23. The second limiting rod 4 is simultaneously accommodated in the other end of the second branch pipe 21 and the fourth end cap 24. Thus, the lower guardrail assembly 2 is fixedly connected to the first limiting rod 3 and the second limiting rod 4.
