The composite plastic produced has the advantages of light weight, corrosion resistance, and low thermal conductivity. Pigments can also be mixed into various colors. It is often used to make ditch covers and floors. However, general sealing covers are mostly made of horizontal frames with FRP sheets. Most of the contact points are on the periphery, with fewer support points in the middle. The impact resistance is poor, and there is a risk of stepping on air, so modifications should be made.

[0026] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, before the transverse rods 6 and the longitudinal rods 5 are welded, cross blocks 7 are pre-assembled at each intersection. Since the transverse grooves 16 are located behind the vertical grooves 15, the three transverse rods 6 are respectively located behind the seven groups of longitudinal rods 5, and are fixed together with the glass fiber reinforced plastic plates 14 through the sponge strips 17 in front, forming a reinforcement structure at the rear of the object to prevent the glass fiber reinforced plastic plates 14 from falling directly into the groove after being broken.

[0027] Embodiment 2: The outer periphery of the glass fiber reinforced plastic plate 14 is wrapped with a fixing frame 4, and a clamping block 12 is longitudinally welded on the right side of the glass fiber reinforced plastic plate 14. The clamping block 12 is embedded in the socket 11 of the outer frame 1. The glass fiber reinforced plastic plate 14 and the fixing frame 4 are in the same vertical plane, and the glass fiber reinforced plastic plate 14 can move left and right along the inner wall of the socket 11;

[0028] Specifically, Figure 1 and Figure 3 As shown, along the card slot 3 around the inner circle of the outer frame 1, the glass fiber reinforced plastic plate 14 is inserted horizontally from the socket 11 on the right side. The outer periphery of this object is locked by the fixed frame 4 to prevent deformation, and the size is adapted to the rectangular slot 2 inside the outer frame 1. The card block 12 stays on the right side of the socket 11 to remove the glass fiber reinforced plastic plate 14, so as to facilitate the replacement of the broken glass fiber reinforced plastic plate 14 inside.

[0029] Embodiment 3: A slot 8 is provided at the upper and lower parts of the right side of the outer frame 1, and a damping sleeve 18 is fixedly connected to the inner wall of the slot 8, and a sleeve block 19 is fixedly connected to the right side between the damping sleeve 18 and the slot 8, and an active chamber 10 is provided at the upper and lower parts of the left side of the outer frame 1, and an anti-slip sleeve 24 is inserted on the left side of the active chamber 10, a limiting rod 13 is welded on the right side of the active chamber 10, and an anti-slip block 23 is welded on the left side of the limiting rod 13, and the anti-slip block 23 is internally welded. The top and bottom ends of the 13 are respectively provided with bead grooves 25, and steel balls 20 are movably embedded inside the bead grooves 25. The outer part of the limit rod 13 is movably sleeved with a latch 9, and a shift block 22 is welded on the right side of the latch 9. A cylindrical groove 21 is provided between the two sides of the inside of the latch 9. The limit rod 13 is transversely embedded in the inside of the cylindrical groove 21.

[0030] Specifically, Figure 1 , Figure 4 and Figure 5As shown, the shift block 22 is pushed to the left along the limit rod 13 inside the movable chamber 10, so that the welded pin 9 enters the slot 8 of the corresponding outer frame 1, and is locked and fixed by the sponge strip 17 and the damping sleeve 18. At this time, the pin 9 is also lubricated by the steel ball 20 in the anti-slip block 23, and can only limit its own sliding distance along the cylindrical groove 21, which can prevent the pin 9 from escaping from the movable chamber 10 and help it enter the slot 8 quickly and accurately, thereby extending and assembling the reinforced fiberglass cover.

[0031] Working principle: When the utility model is used, firstly, along the card slot 3 around the inner circle of the outer frame 1, the glass fiber reinforced plastic plate 14 is inserted horizontally from the right side of the socket 11. The outer periphery of the object is locked by the fixed frame 4 to prevent deformation, and the size is adapted to the rectangular slot 2 inside the outer frame 1, and the card block 12 stays on the right side of the socket 11. In order to take out the glass fiber reinforced plastic plate 14, the installation, limiting and easy disassembly are integrated. Before welding, the transverse rod 6 and the longitudinal rod 5 are pre-assembled with the cross block 7 at each intersection. Because the transverse groove 16 is located behind the vertical groove 15, the three transverse rods 6 are respectively located behind the seven groups of longitudinal rods 5, and are connected to the glass through the sponge strip 17 in front. The steel plates 14 are fixed together to form a reinforcement structure at the rear of the object, which prevents the glass fiber reinforced plastic plate 14 from falling directly into the groove after being broken, and also improves the structural strength of the cover. Finally, the block 22 is pushed to the left along the limit rod 13 inside the active chamber 10, so that the welded pin 9 enters the slot 8 of the corresponding outer frame 1 and is locked and fixed by the sponge strip 17 and the damping sleeve 18. At this time, the pin 9 is also lubricated by the steel ball 20 in the anti-slip block 23, and can only limit its sliding distance along the cylindrical groove 21, which not only prevents the pin 9 from leaving the active chamber 10, but also helps the object to quickly and accurately enter the slot 8, thereby realizing the assembly of the glass fiber reinforced plastic cover.
