Therefore, they should not be understood as limiting the scope of protection of the present invention. Example 1

[0038] like Figure 1-8 As shown, the utility model provides a road construction safety fence, including a baffle 1, two docking protrusions 11 are provided in the left extension direction of the baffle 1, and two docking grooves 12 are provided in the right extension direction of the baffle 1 for matching with the docking protrusions 11. The two adjacent baffles 1 are connected by a rotating rod 5 that passes through the docking protrusions 11 and the docking grooves 12. When the fence needs to be turned, the matching relationship between the docking protrusions 11 and the docking grooves 12 and the rotating rod 5 can be used to achieve it, so that the baffle 1 can be connected and enclosed around the construction site as needed to ensure the safety of the construction. Two left-right symmetrical and retractable leg groups 6 are provided at the bottom of the baffle 1. The leg group 6 can support the baffle 1 and make it stand on the ground. The leg group 6 is controlled by a pushing mechanism 2 arranged in the baffle 1, and the extension and retraction of the leg group 6 is controlled by the pushing mechanism 2 so that the leg group 6 can be extended when in use and retracted when not in use.

[0039] In the above scheme, a limiting clamping rod 51 is provided on the top of the rotating rod 5, and two corresponding clamping grooves 15 are provided on the right side of the top of the baffle 1. Two limiting grooves 151 with the same rotation direction are penetrated on the inner wall of the clamping groove 15, and the clamping rod 51 is clamped into the limiting groove 151 through the clamping groove 15.

[0040] As an optimized technical solution of the present invention, after the rotating rod 5 connects the two baffles 1 together, the locking rod 51 can be pressed into the locking groove 15, and then the rotating rod 5 is rotated to rotate the locking rod 51 into the limit groove 151, thereby preventing the rotating rod 5 from accidentally slipping out and ensuring the effectiveness of the connection between the baffles 1.

[0041] In the above scheme, two downward-opening receiving grooves 14 are symmetrically provided at the bottom of the baffle 1, and the connecting block 3 is slidably connected in the receiving groove 14. The leg group 6 is connected to the bottom of the connecting block 3, and the pushing mechanism 2 is connected to the top of the connecting block 3.

[0042] As an optimized technical solution of the present invention, sliding grooves 141 are provided on the left and right sides of the accommodating groove 14, and guide sliding blocks 31 are respectively provided on the left and right sides of the connecting block 3. The guide sliding blocks 31 are slidably connected in the sliding grooves 141, so that the connecting block 3 can slide in the accommodating groove 14, so as to drive the leg group 6 to extend or retract.

[0043] In the above scheme, the pushing mechanism 2 includes a pushing rod 21, a first spring 22 and a pin 23. A pushing groove 13 is provided above the accommodating groove 14. The pushing rod 21 is movably connected in the pushing groove 13. The lower end of the pushing rod 21 passes through the bottom of the pushing groove 13 and is rotatably connected to the top of the connecting block 3. The pin 23 is connected to the upper end of the pushing rod 21. The first spring 22 is squeezed in the pushing groove 13 through the pin 23, and the first spring 22 is sleeved on the lower end of the pushing rod 21.

[0044] As an optimized technical solution of the present invention, the push rod 21 can slide up and down in the push groove 13, thereby driving the connecting block 3 connected to its lower end to slide. By applying a downward force on the pin 23 to drive the push rod 21 to slide down, the first spring 22 is compressed, and the pin 23 is released. Under the action of the restoring elastic force of the first spring 22, the push rod 21 can be restored to its initial position.

[0045] In the above solution, a latch groove 131 is provided inside the pushing groove 13 , and a limiting component 4 for limiting the latch pin 23 is provided inside the latch groove 131 .

[0046] As an optimized technical solution of the present invention, when the pin 23 slides down to the slot 131, the leg group 6 has been driven by the push rod 21 through the connecting block 3 to completely extend out of the accommodating slot 14, and then the pin 23 can be turned into the slot 131 for fixation to ensure that the leg group 6 is in a supported state. In order to prevent the pin 23 from slipping out of the slot 131, the pin 23 can be restricted by the limit assembly 4 so that it slides out and the leg group 6 loses its supporting effect. Example 2

[0047] like Figure 3 、 4 As shown in and 7, based on Example 1, the difference from Example 1 is that the leg group 6 includes a leg 61 and a torsion spring 62, the number of the legs 61 is two, and the upper ends are rotatably connected to the front and rear sides of the bottom of the connecting block 3, the torsion spring 62 is arranged at the connection of the legs 61, and the front and rear sides of the lower end of the accommodating groove 14 are respectively provided with a guide groove 142, the guide groove 142 is an eight-shaped structure, and the leg 62 is slidably connected in the guide groove 142.

[0048] As an optimized technical solution of the present invention, when the support leg group 6 is in an extended state, the support leg 61 can be attached to the inner wall of the guide groove 142 under the elastic force of the torsion spring 62, presenting the same figure-eight structure as the guide groove 142, so that the support leg 6 can be spread out at the bottom of the baffle 1 to play a supporting effect, so as to improve the stability of the support. Example 3

[0049] like Figure 1 、 3 , 5 and 8, based on Example 1, the difference from Example 1 is that, in the above scheme, the limiting assembly 4 includes a telescopic pin 41 and a second spring 42, and two inward-opening corresponding limiting holes 132 are provided at the opening of the pin slot 131, the telescopic pin 41 is arranged at the opening of the limiting hole 132, and the second spring 42 is squeezed into the limiting hole 132 through the telescopic pin 41.

[0050] As an optimized technical solution of the present invention, the distance between the two corresponding telescopic pins 41 is smaller than the diameter of the bayonet 23. When the bayonet 23 rotates in or out of the bayonet slot 131, a certain force needs to be applied to the bayonet 23 to force the telescopic pin 41 to retract into the limiting hole 132. After the bayonet 23 rotates in or out, under the elastic force of the second spring 42, the telescopic pin 41 returns to its initial state to prevent the bayonet 23 from being accidentally rotated out.

[0051] Specific implementation cases:

[0052] When the construction site needs to be fenced, the baffles 1 can be moved to the periphery of the construction site, and then the baffles 1 can be connected one by one through the rotating rods 51 to have a sufficient length to fence the construction site.

[0053] After the baffle 1 is strung together, the leg group 6 at the bottom of the baffle 1 can be pushed out through the pushing mechanism 2 to support the baffle 1. The pushing mechanism 2 can push the pushing rod 21 downward along the pushing groove 13 through the latch 23 until the latch 23 is located at the latch groove 131. By rotating and squeezing the latch 23, it is rotated into the latch groove 131 through the limiting component 4 to complete the limiting of the latch 23. In the process of the pushing rod 21 being pushed downward, the connecting block 3 will be driven to slide downward along the sliding groove 141 in the accommodating groove 14, thereby making the leg group 6 extend out of the bottom of the baffle 1 to support the baffle 1. In the process of extending the leg group 6, the leg 61 will slide out along the guide groove 142 under the elastic force of the torsion spring 62, thereby making the leg 61 spread out in an eight-shaped shape to improve the stability of the support.

[0054] Finally, when the construction of the barrier is completed and the enclosure needs to be stored, the rotating rod 5 is rotated to make the locking rod 51 rotate out of the limit groove 151, and then pulled out along the locking groove 15, and then the baffles 1 are separated one by one, and then the locking pin 23 is rotated out of the locking pin groove 131. Under the elastic force of the first spring 22, the push rod 21 is used to retract it into the receiving groove 14 through the connecting block 3 support leg group 6, thereby ensuring that the outer surface of the baffle 1 is flat, so as to facilitate the stacking of the baffle 1. At the same time, it is also beneficial for the construction workers to carry it, and greatly reduces the bumps during transportation. It can also prevent the loss of parts and affect the normal use of the baffle 1.

[0055] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
