For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Example

[0037] like Figure 1-5 As shown, a construction fence proposed in the present application includes a base 1 and a support sleeve 4 connected to the upper end thereof, the base 1 is fixedly connected to the support sleeve 4, and also includes:

[0038] The telescopic components 2 are arranged at both ends of the base 1, and the top ends of the two telescopic components 2 are commonly connected to a top plate 3. The telescopic components 2 include a connecting tube 21 fixedly connected to the upper end of the base 1, and a telescopic rod 22 is slidably inserted at the upper end of the connecting tube 21, and the top plate 3 is fixedly connected to the top of the telescopic rod 22; an inner groove is opened inside the connecting tube 21, and both side surfaces of the bottom end of the telescopic rod 22 are fixedly connected with protrusions 23, and the two protrusions 23 slide in the inner groove to limit the telescopic rod 22, thereby preventing the telescopic rod 22 from detaching from the connecting tube 21 after moving upward.

[0039] It also includes a guard plate 5 connected to the bottom end of the top plate 3 and inserted into the inside of the support sleeve 4. The guard plate 5 can be retracted and extended by lifting and lowering the top plate 3.

[0040] A positioning mechanism 6 is arranged on the outside of the two telescopic components 2, and the positioning mechanism 6 is arranged at one end of the telescopic rod 22 away from the supporting sleeve 4, and the positioning mechanism 6 is used to limit the expansion of the telescopic component 2; the positioning mechanism 6 includes an operating cylinder 61 fixedly connected to the side of the connecting cylinder 21, and a first piston plate 62 is slidably connected inside the operating cylinder 61, and the inner end of the first piston plate 62 is connected to a limiting plate 64 through a connecting block 63, and the limiting plate 64 slides through the outer surface of the connecting cylinder 21; the upper corner of the inner end of the limiting plate 64 is set to an arc-shaped portion 65, when the telescopic rod 22 is raised, the limiting plate 64 can be smoothly pushed to the bottom end of the telescopic rod 22, and the outer surface of the first piston plate 62 is fixedly connected to a pull rod 67, and the outer end of the pull rod 67 extends to the outside of the operating cylinder 61.

[0041] It also includes a balance support rod 8 slidably connected to both sides of the bottom end of the telescopic component 2, and the balance support rod 8, the telescopic component 2 and the ground form a triangle. It also includes a pneumatic component 7, which is arranged at the bottom end of the positioning mechanism 6 and is used to adjust the retracted and extended state of the balance support rod 8. The pneumatic component 7 includes an air cylinder 71 fixedly connected to the bottom end of the operating cylinder 61, and the lower surface of the operating cylinder 61 is provided with a through hole 66 connected to the air cylinder 71. The inside of the air cylinder 71 is slidably connected to a second piston plate 74, and the bottom end of the second piston plate 74 is fixedly connected to a pneumatic plate 72, and both sides of the bottom end of the pneumatic plate 72 are fixedly connected to L-shaped connecting rods 73, and the two L-shaped connecting rods 73 are fixedly connected to two U-shaped blocks 9 respectively. The inner wall of the bottom end of the air cylinder 71 is fixedly connected to a return strip, which is used to limit the second piston plate 74 to prevent the second piston plate 74 from detaching from the air cylinder 71.

[0042] Among them, sliding grooves are symmetrically opened on both sides of the connecting tube 21, and the connecting end of the balance support rod 8 is slidably set in the sliding groove through the U-shaped block 9, and the balance support rod 8 is rotatably connected to the U-shaped block 9; a limiting rope 10 is connected between the balance support rod 8 and the connecting tube 21, which is used to limit the opening angle of the balance support rod 8, so that the balance support rod 8 can be normally stressed after sliding down and opening, and a roller is provided at the bottom end of the balance support rod 8, which reduces the friction with the ground when the balance support rod 8 opens outward.

[0043] The working principle of this embodiment is as follows: when using the fence, first place the fence at the designated position, then lift the top plate 3 upwards, so that the two telescopic rods 22 extend out of the connecting tube 21 until the protrusion 23 contacts the top wall of the inner groove. Then push the pull rod 67 toward the inside of the operating tube 61, so that the first piston plate 62 moves toward the inside of the operating tube 61, so that the limit plate 64 moves to the bottom end of the telescopic rod 22, and the support positioning of the telescopic rod 22 is completed. The operation is simple and fast, and the stability is good. When the first piston plate 62 moves toward the inside of the operating tube 61, the gas inside the operating tube 61 will be squeezed into the air cylinder 71 through the port 66, and the second piston plate 74 will move downward under the action of air pressure, and then the two L-shaped connecting rods 73 will be driven downward through the pneumatic plate 72, and finally the two U-shaped blocks 9 will be driven downward, so that the balance support rod 8 moves downward and opens outward, which plays a role in stabilizing the support of the telescopic assembly 2. When the fence needs to be folded up, the pull rod 67 is pulled outward to make the limit plate 64 move away from the bottom end of the telescopic rod 22, thereby giving up the support and positioning of the telescopic rod 22. The pull rod 67 moves outward and drives the first piston plate 62 to move outward, so that the gas in the air cylinder 71 is sucked into the operating cylinder 61, so that the pneumatic plate 72 moves upward under the action of negative pressure, and then drives the U-shaped block 9 to move upward through the L-shaped connecting rod 73, so that the balance support rod 8 moves upward and is folded (after the balance support rod 8 moves upward, it will move vertically downward and stick to the connecting cylinder 21 under the action of its own gravity), thereby further saving the floor space of the fence during transportation.

Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
