During the adjustment operation using this device, it is only necessary to rotate the screw 21 upward, and then adjust the height of the guardrail by rotating the knob 14.

[0020] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a protective fence for metal smelting safety management, including a first connecting plate 1, a second connecting plate 3, a first fixed plate 4 and a second fixed plate 5, two protective sleeves 2 are fixed to the top of the first connecting plate 1, the two protective sleeves 2 pass through the second connecting plate 3, a connecting shell 7 is fixed to the top of the second connecting plate 3, a moving rod 8 is slidably connected in the protective sleeve 2, the moving rod 8 is fixed to the first fixed plate 4, and a limiting strip 10 is fixed on the side where the two moving rods 8 are close to each other, and the two limiting strips 10 are mutually A plurality of slots are provided on the side close to each other, and a moving block 15 is slidably connected inside the connecting shell 7. The top of the moving block 15 is rotatably connected with a screw rod 21, which penetrates and is screwed on the top of the connecting shell 7. Sliding rods 16 are slidably connected to the inner walls of both sides of the connecting shell 7. The sliding rods 16 are in contact with both sides of the moving block 15. Insert rods 17 are fixed on the sides of the two sliding rods 16 that are away from each other. The insert rods 17 penetrate the connecting shell 7 and are inserted into the slots. A spring 18 is fixed between the side of the sliding rod 16 away from the moving block 15 and the connecting shell 7. The second connecting plate 3 has a hollow interior, and a rotating shaft 20 is rotatably connected between the inner walls at both ends thereof, a rack 9 is fixed to one side of one moving rod 8 close to the connecting shell 7 and the other side of the moving rod 8 away from the connecting shell 7, two connecting rods are rotatably connected between the inner walls at both ends of the second connecting plate 3, and gears 19 are fixed to the outer walls of the two connecting rods, which mesh with the rack 9, a driving wheel is fixed to the outer wall of the rotating shaft 20, and a driven wheel is fixed to the outer wall of the connecting rod, and a belt is arranged between the driving wheel and the driven wheel, and the rotating shaft 20 passes through one end of the second connecting plate 3 and a knob 14 is fixed to its outer wall. A sliding groove is provided on the inner wall of the connecting shell 7, and a fixed block is fixed to one end of the moving block 15, and the fixed block slides in the sliding groove.

[0021] It should be noted that by rotating the screw 21, the screw 21 drives the moving block 15 to move upward, so that the spring 18 drives the two sliding rods 16 to move in the direction of approaching each other, and the insertion rod 17 moves out of the slot and no longer limits and fixes the limit strip 10. In this way, the height of the guardrail can be adjusted, and there is no need to perform other work while adjusting, and only one screw 21 needs to be rotated to stop limiting the limit strip 10. Then, by turning a knob 14, the knob 14 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the driving wheel to rotate, the driving wheel drives the belt to move, and the belt drives the driven wheel to rotate. In this way, the two gears 19 can be rotated, so that the two racks 9 can be moved upward to adjust the height of the guardrail. After adjusting to the specified height, the screw 21 is rotated in the opposite direction, the moving block 15 moves downward, and the insertion rod 17 is inserted into the slot to limit and fix the limit strip 10. Its operation is simpler and does not require much effort.

A first fixing rod 11 and a second fixing rod 12 are fixed between the top of the first connecting plate 1 and the bottom of the second connecting plate 3 and the top of the first fixing plate 4 and the bottom of the second fixing plate 5, and the first fixing rod 11 and the second fixing rod 12 are fixed to each other. A mounting plate 13 is fixed to the top of the moving rod 8, and a bolt is screwed between the mounting plate 13 and the bottom of the first fixing plate 4.

[0023] It should be noted that, by providing the reflective strip 6, it is convenient for users to see the fence when traveling at night to avoid accidents.

[0024] Working principle: When the height of the fence needs to be adjusted, the screw rod 21 is rotated, and the screw rod 21 drives the moving block 15 to move upward, so that the spring 18 drives the two sliding rods 16 to move in a direction close to each other, and the insertion rod 17 moves out of the slot and no longer limits and fixes the limit strip 10. Then, by turning a knob 14, the knob 14 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the driving wheel to rotate, the driving wheel drives the belt to move, and the belt drives the driven wheel to rotate, so that the two gears 19 can rotate, so that the two racks 9 can move upward to adjust the height of the guardrail. After adjusting to the specified height, the screw rod 21 is rotated in the opposite direction, the moving block 15 moves downward, and the insertion rod 17 is inserted into the slot to limit and fix the limit strip 10.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
