Detailed implementation method:
[0011] Reference Figures 1-4 The highway construction protective fence is characterized by comprising: a fixed base 1 and a plurality of fixed ground nails 2 evenly distributed and connected to the lower surface of the fixed base 1; a fixed post 3 connected to the middle of the upper surface of the fixed base 1; locking devices 4 symmetrically inserted above the left and right side surfaces of the fixed post 3; connecting devices 5 symmetrically inserted above the left and right side surfaces of the fixed post 3; a connecting crossbar 6 inserted at the center of the outer surface of each connecting device 5; and a protective device inserted at the middle of the upper surface of the connecting crossbar 6. The protective baffle 7, the locking device 4 includes an upper plate 4-1, a spring 4-2, a locking post 4-3, and a lever 4-4. The spring 4-2 is connected to the middle of the upper inner surface of the upper plate 4-1. The locking post 4-3 is inserted into the middle of the lower lower surface of the upper plate 4-1. The lever 4-4 is connected to the middle of the upper outer surface of the locking post 4-3. The locking post 4-3 is T-shaped. The lower surface of the spring 4-2 is connected to the upper surface of the locking post 4-3. The lower edge of the outer surface of the locking post 4-3 is sloped. The connecting device 5... The assembly includes a insert plate 5-1, a tension spring 5-2, a support plate 5-3, and a locking hole 5-4. The tension spring 5-2 is connected to the middle of the inner surface of the insert plate 5-1. The support plate 5-3 is connected to the middle of the inner surface of the insert plate 5-1. The locking hole 5-4 is located in the middle of the inner surface of the upper surface of the support plate 5-3. The inner edge of the upper surface of the support plate 5-3 is sloped. The connecting crossbar 6 is inserted into the middle of the outer surface of the insert plate 5-1. The outer surface of the tension spring 5-2 is connected to the side surface of the connecting crossbar 6. The support plate 5-1... 3 is inserted into the fixed column 3, and the locking post 4-3 is inserted into the locking hole 5-4. The protective baffle 7 includes a locking plate 7-1, a handle post 7-2, a partition 7-3, and an adhesive strip 7-4. The handle post 7-2 is symmetrically connected to the middle of the left and right sides of the upper surface of the locking plate 7-1. The partition 7-3 is connected to the middle of the lower surface of the locking plate 7-1. Adhesive strips 7-4 are connected to the lower edge of the side surface of the partition 7-3. The partition 7-3 penetrates the upper connecting crossbar 6 and is inserted into the lower connecting crossbar 6.
[0012] In use, the operator first erects several fixed columns 3 on the ground, ensuring the fixed base 1 is in contact with the ground while inserting the fixed ground nails 2 into the ground. Then, the operator holds the insert plates 5-1 on the connecting devices 5 at both ends of the connecting crossbar 6, places the connecting crossbar 6 between two fixed columns 3, and pulls the insert plates 5-1 outward to slide them on the connecting crossbar 6. At the same time, the support plate 5-3 is inserted into the fixed column 3, and passes through the ramp at the outer edge of the upper surface of the insert plate 5-3 and the locking post 4 on the locking device 4. -3 The ramp at the lower edge of the outer surface of the plate 4-3 pushes the locking post 4-3, causing the locking post 4-3 to slide upward within the upper plate 4-1. Then, when the locking post 4-3 is aligned with the locking hole 5-4, the spring 4-2 pushes the locking post 4-3 to insert it into the locking hole 5-4, thus locking the insert plate 5-3. Finally, the worker holds the handles 7-2 on the left and right protective baffles 7 and inserts the partition 7-3 through the upper connecting crossbar 6 into the lower connecting crossbar 6. At the same time, the locking plate 7-1 is locked on the upper surface of the upper connecting crossbar 6 and the adhesive strip 7-4 is inserted into the lower connecting crossbar 6.
[0013] During disassembly, the worker pushes the lever 4-4 upwards, which simultaneously causes the locking post 4-3 to slide upwards. Then, when the locking post 4-3 separates from the locking hole 5-4, the tension spring 5-2 pulls the insert plate 5-1 to make the insert plate 5-3 exit from the fixed column 3, thus allowing disassembly.
[0014] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
