In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0022] Example 1

[0023] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a quick-connect guardrail for road construction, including a guardrail body 1. The number of guardrail bodies 1 is two, a positioning hole 2 is opened on the left side of the top of the guardrail body 1, a load-bearing mechanism 3 is arranged at the bottom of the guardrail body 1, and a connecting mechanism 4 is arranged on the right side of the top of the guardrail body 1, and the connecting mechanism 4 includes a connecting box 41, and the connecting boxes 41 are distributed on the front and back of the guardrail body 1, the top of the connecting box 41 is movably connected with a T-plate 42, and the bottom of the T-plate 42 is fixedly connected with a positioning rod 43, one side of the inner cavity of the connecting box 41 is movably connected with a gear 44 through a bearing, and one side of the inner cavity of the connecting box 41 is provided with a tooth plate 45, the top of the tooth plate 45 is fixedly connected to the T-plate 42, the gear 44 and the tooth plate 45 are meshed, and one side of the gear 44 is fixedly connected with a connecting cylinder 46, the inner cavity of the connecting cylinder 46 is provided with a fixing rod 47, and the surface of the fixing rod 47 is sleeved with a torsion spring 48.

[0024] The bottom of the positioning rod 43 extends to the inner cavity of the positioning hole 2 and is movably connected to the inner cavity of the positioning hole 2. The end of the connecting tube 46 away from the gear 44 is movably connected to the inner wall of the connecting box 41 through a bearing. One end of the fixing rod 47 is fixedly connected to the inner wall of the connecting box 41. One end of the torsion spring 48 is fixedly connected to the fixing rod 47, and the end of the torsion spring 48 away from the fixing rod 47 is fixedly connected to the inner wall of the connecting tube 46.

[0025] like Figure 1-3 As shown, the guardrail body 1 is detachably arranged, so that the two guardrail bodies 1 can be disassembled and separated, which is convenient for people to carry and use, and there is no need to carry it as a whole, which improves the convenience of use. During use, the stability of the guardrail body 1 can be ensured by the load-bearing mechanism 3, and in the connection process, by aligning the two guardrail bodies 1 with the load-bearing mechanism 3 and loosening the T-plate 42, the torsion spring 48 loses its tension, and then the reset force of the torsion spring 48 will drive the connecting tube 46 to rotate. When the connecting tube 46 rotates, it will also drive the gear 44 to rotate, so that the gear 44 drives the tooth plate 45 to move downward. When the tooth plate 45 moves downward, it also drives the T-plate 42 and the positioning rod 43 to move downward, so that the positioning rod 43 enters the inner cavity of the positioning hole 2, thereby realizing the rapid connection of the two guardrail bodies 1, which is convenient for use in later road construction.

[0026] Example 2

[0027] Reference Figure 1-3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0028] In this embodiment, a slot 11 is provided on the left side of the guardrail body 1, and a clip 12 is fixedly connected to the right side of the guardrail body 1. The left clip 12 extends to the inner cavity of the right slot 11 and is movably connected to the inner cavity of the right slot 11.

[0029] A pull frame 421 is fixedly connected to the top of the T-shaped plate 42, a limiting block 451 is fixedly connected to one side of the tooth plate 45, a limiting groove 411 is opened on one side of the inner cavity of the connecting box 41, and the limiting block 451 extends from one end of the tooth plate 45 to the inner cavity of the limiting groove 411 and is slidably connected to the inner cavity of the limiting groove 411.

[0030] like Figure 1-3 As shown, the left side guardrail body 1 drives the left side clamping strip 12 to be inserted into the inner cavity of the right side clamping slot 11, thereby ensuring the stability of the clamping of the two guardrail bodies 1 and preventing misalignment. At the same time, the pull frame 421 facilitates pulling the T-shaped plate 42 to move up and down. When the tooth plate 45 moves up and down, it drives the limit block 451 to slide along the inner cavity trajectory of the limit slot 411, thereby ensuring the stability of the tooth plate 45 during movement.

[0031] Example 3

[0032] Reference Figure 1 and 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0033] In this embodiment, the load-bearing mechanism 3 includes a bottom box 31, the top of the bottom box 31 is fixedly connected to the guardrail body 1, the top of the bottom box 31 is connected to a water injection pipe 32, the front of the bottom box 31 is connected to a drainage pipe 33, and the surfaces of the drainage pipe 33 and the water injection pipe 32 are both threadedly connected with a closed sleeve.

[0034] A first magnet 34 is fixedly connected to the left side of the bottom box 31 , and a second magnet 35 is fixedly connected to the right side of the bottom box 31 . The second magnet 35 on the left side contacts the first magnet 34 on the right side, and the first magnet 34 and the second magnet 35 are magnetically connected.

[0035] like Figure 1 and 4 As shown, the water inside the bottom box 31 is discharged through the drain pipe 33 to reduce the weight of the bottom box 31 and facilitate the subsequent picking up and carrying operations. At the same time, water can be injected into the bottom box 31 through the water injection pipe 32 to increase the weight of the bottom box 31, thereby ensuring the stability of the guardrail body 1 when in use. By contacting the second magnet 35 on the left side with the first magnet 34 on the right side, the first magnet 34 and the second magnet 35 will be magnetically connected, thereby ensuring the firmness of the contact between the two bottom boxes 31 and the two guardrail bodies 1.

[0036] When in use, first drain the water inside the bottom box 31 through the drain pipe 33 to reduce the weight of the bottom box 31, pull the pull frame 421, the pull frame 421 drives the T-plate 42 and the positioning rod 43 to move upward, the T-plate 42 drives the toothed plate 45 upward, so that the toothed plate 45 drives the gear 44 and the connecting tube 46 to rotate, and the connecting tube 46 will drive the torsion spring 48 to deform, and at the same time the positioning rod 43 upwardly disengages from the inner cavity of the positioning hole 2, thereby releasing the connection between the two guardrail bodies 1. The guardrail body 1 is detachably arranged, and then when the two guardrail bodies 1 are disassembled and separated, it is convenient for personnel to carry and use them, without the need for overall transportation, thereby improving the convenience of use. When they need to be connected again after being carried to the use position, by aligning the two guardrail bodies 1 with the bottom box 31, the second magnet 35 on the right side of the left bottom box 31 will align with the second magnet 35 on the right side of the left bottom box 31. The first magnet 34 on the left side of the bottom box 31 contacts, which will cause the first magnet 34 and the second magnet 35 to be magnetically connected, ensuring the firmness of the contact between the two bottom boxes 31 and the two guardrail bodies 1. Then, the T-plate 42 is loosened, and the torsion spring 48 loses its tension, and the restoring force of the torsion spring 48 drives the connecting tube 46 to rotate. The connecting tube 46 rotates and the gear 44 rotates, so that the gear 44 drives the tooth plate 45 to move downward. The tooth plate 45 moves downward and drives the T-plate 42 and the positioning rod 43 downward, so that the positioning rod 43 enters the inner cavity of the positioning hole 2, thereby realizing the rapid connection of the two guardrail bodies 1. At the same time, water is injected into the bottom box 31 through the water injection pipe 32 to increase the weight of the bottom box 31, thereby ensuring the stability of the guardrail body 1 and facilitating its use in later road construction.
