[0003] Utility model patent CN218265311U discloses a metal guardrail, relating to the field of metal guardrail technology. This utility model includes two symmetrically arranged side support rods, with a crossbar fixed between the two side support rods via an insert-end cylinder and a first fastening bolt; connecting end cylinders are linearly arranged on the opposite surfaces of adjacent crossbars; an extension rod is sleeved between the corresponding connecting end cylinders located between the opposite surfaces of adjacent crossbars; threaded end cylinders are provided on the opposite sides of the bottom ends of both side support rods; a bidirectional threaded rod is threadedly connected to both side support rods; and several pointed tips are fixed on the upper side of the topmost crossbar located between the two side support rods. When the bidirectional threaded rod rotates, it engages with the threaded end cylinders of the two side support rods and moves relative to each other. The two side support rods respectively pull the multiple staggered crossbars to move, and the connecting end cylinders and extension rods between adjacent crossbars are interlocked, allowing for convenient adjustment of the overall length of the metal guardrail, making it highly versatile.

[0004] However, the device has certain shortcomings in use. The grid and crossbars of the device are generally connected by hinges or spot welding, resulting in low overall strength and easy breakage upon impact. In addition, the device is not convenient to assemble and disassemble on the ground. Utility Model Content

[0017] Please see Figure 1 A high-strength metal guardrail includes a post 1, a base 2 fixedly connected to the lower end of the post 1, a tube 3 slidably connected inside the base 2, a reinforcing mechanism 4 provided on the tube 3, a crossbar 5 fixedly connected to the surface of the post 1, a grid 6 welded to the surface of the crossbar 5, and a reinforcing mechanism 7 provided on the grid 6.

[0018] Please see Figures 1-3The reinforcement mechanism 4 includes a baffle 41. The baffle 41 is fixedly connected to the outer side of the insert 3. The lower surface of the baffle 41 contacts the base 2. A screw 42 is threadedly connected to the inside of the insert 3. A square rod 43 is slidably connected to the inside of the screw 42. A handle 44 is fixedly connected to the upper end of the square rod 43. The handle 44 contacts the base 2. By setting the handle 44, the square rod 43 is rotated. A screw cylinder 45 is threadedly connected to the outer side of the screw 42. A connecting rod 46 is hinged to the outer side of the screw cylinder 45. A tooth is hinged to the end of the connecting rod 46. Plate 47, toothed plate 47 and insert 3 are slidably connected. A spring 48 is provided on the outside of screw 42. One end of spring 48 is in contact with insert 3 and the other end of spring 48 is fixedly connected to screw 45. By setting spring 48, screw 45 is assisted to reset and enter the ground through insert 3. Square rod 43 drives screw 42 to rotate, which in turn causes screw 45 to drive connecting rod 46 to move, so that toothed plate 47 extends and retracts in insert 3. Thus, by controlling the engagement and disengagement of toothed plate 47 and the ground, the device can be easily assembled, disassembled and fixed on the ground.

[0019] Please see Figure 1 , Figure 4 The reinforcing mechanism 7 includes a limiting plate 71. The limiting plate 71 is fixedly connected inside the grille 6. An insert rod 72 is slidably connected inside the grille 6, and the insert rod 72 is slidably connected to the crossbar 5. A guide rod 73 is fixedly connected to the surface of the limiting plate 71, and the guide rod 73 is slidably connected to the insert rod 72. A compression spring 74 is provided on the outer side of the guide rod 73. One end of the compression spring 74 is fixedly connected to the limiting plate 71, and the other end of the compression spring 74 is fixedly connected to the insert rod 72. By providing the compression spring 74, the insert rod 72 can be easily reset. A sliding pin 75 is fixedly connected to the outer side of the insertion rod 72. The sliding pin 75 is slidably connected to the grid 6. A sliding ring 76 is fixedly connected to the surface of the sliding pin 75. The sliding ring 76 is slidably connected to the grid 6. By setting the sliding ring 76, the movement of the insertion rod 72 is controlled. The compression spring 74 acts on the insertion rod 72, causing the insertion rod 72 to slide into the crossbar 5 within the grid 6. This strengthens the connection between the grid 6 and the crossbar 5, preventing breakage at the weld joint due to external impact, thus increasing the overall structural strength of the device.

[0020] Working principle: During welding, the slip ring 76 is manually moved to move the insertion rod 72 into the grid 6, which compresses the spring 74. Then, the grid 6 is moved between the two crossbars 5. The slip ring 76 is released, and the spring 74 returns to its original position, allowing the insertion rod 72 to re-enter the grid 6. Then, the contact position between the grid 6 and the crossbar 5 is welded. The spring 74 acts on the insertion rod 72, causing the insertion rod 72 to slide into the crossbar 5 within the grid 6, thus strengthening the connection between the grid 6 and the crossbar 5 and preventing breakage at the weld joint due to external impact, resulting in a higher overall structural strength of the device. During installation, holes are drilled at the corresponding positions on the ground, and the insert 3 is inserted into the holes. The square rod 43 is manually rotated by the handle 44. The square rod 43 drives the screw 42 to rotate. The rotation of the screw 42 and the screw 45 make a threaded movement, which in turn causes the screw 45 to move. The screw 45 drives the connecting rod 46 to move, which causes the toothed plate 47 to extend and retract inside the insert 3. The device can be easily disassembled and fixed on the ground by controlling the engagement and disengagement of the toothed plate 47 and the ground.
