DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 2 and Figure 4 As shown, the utility model provides the following technical solutions: a glass fiber reinforced plastic pultruded drain trough which is easy to install and fix comprises a drain trough body 3, a connecting plate 1 and a grate 7, the connecting plate 1 is a U-shaped plate made of plastic material, and the connecting plate 1 is installed on the outside of one end of the drain trough body 3, the connecting plate 1 is used for connecting and fixing the two ends of the drain trough body 3, the grate 7 covers the surface of the drain trough body 3, and the grate 7 is used to control the opening and closing of the top opening of the drain trough body 3, a plurality of positioning holes 2 are symmetrically provided on the surface of one end of the drain trough body 3 away from the connecting plate 1, fixing parts 5 are symmetrically installed on the inner wall of the connecting plate 1 at equal intervals, the fixing parts 5 are triangular, and the fixing parts 5 are embedded in the positioning holes 2, the inner wall of the connecting plate 1 and the surface of the fixing parts 5 are coated with sealing glue 4, the sealing glue 4 is in contact with the outer wall of the drain trough body 3, and the sealing glue 4 is used to fill the gap between the connecting plate 1 and the outer wall of the drain trough body 3.

[0020] Through the above technical scheme: since the connecting plate 1 is made of plastic material and has a certain flexibility, during installation, the sealing glue 4 is applied to the inner wall of the connecting plate 1 and the surface of the fixing part 5, and the drainage trough body 3 is moved so that its connecting plate 1 is horizontally sleeved on one end of the other drainage trough body 3, and then the drainage trough body 3 is pushed, the connecting plate 1 is deformed by force and forces the fixing part 5 to be embedded into the positioning hole 2. At this time, the connecting plate 1 is reset and hits the drainage trough body 3, and the sound generated by the impact is used to assist the operator to determine whether the positioning is completed, and then the connection is completed by the interlocking connection between the fixing part 5 and the positioning hole 2 instead of the screw, which solves the problem that the current FRP drainage trough is time-consuming and has low installation efficiency. At the same time, the applied sealing glue 4 fills the gap between the connecting plate 1 and the outer wall of the drainage trough body 3, seals the connection between the two drainage trough bodies 3, and further increases the stability of the connection through adhesion, thereby ensuring the normal use of the FRP drainage trough.

[0021] See also Figure 1-Figure 4As shown, auxiliary plates 6 are symmetrically installed at equal intervals on the upper part of the inner wall of the drainage trough body 3, and grooves are opened on the side walls of the auxiliary plates 6. First flexible plastic blocks 9 are symmetrically arranged at both ends of the grooves. Rotating shafts 8 are symmetrically installed on both sides of one end of the grate 7. The rotating shaft 8 is embedded in the groove, and the diameter of the rotating shaft 8 is larger than the distance between the first flexible plastic blocks 9. Second flexible plastic blocks 11 are relatively installed on the side walls of the auxiliary plates 6 on the side of the drainage trough body 3 away from the rotating shaft 8. The second flexible plastic blocks 11 extend to above the grate 7, and the distance between the second flexible plastic blocks 11 is smaller than the length of the grate 7. A movable rod 10 is installed in the middle of one side of the surface of the grate 7. The top of the movable rod 10 is flush with the top of the drainage trough body 3, and an annular auxiliary groove 12 is opened on the side wall of the movable rod 10.

[0022] Through the above technical scheme: during installation, the grate 7 is moved so that the rotating shaft 8 squeezes the first flexible plastic block 9 and then is horizontally embedded in the groove of the side wall of the auxiliary plate 6. The first flexible plastic block 9 is used to block the rotating shaft 8, so that the grate 7 cannot normally detach from the gutter body 3. At this time, the grate 7 is rotated to force the other end of the grate 7 to contact the second flexible plastic block 11, and after squeezing the second flexible plastic block 11, it is moved to the bottom of the second flexible plastic block 11, and the grate 7 is fixed by the second flexible plastic block 11 to keep it in a closed state at all times, thereby simplifying the installation method and improving the installation efficiency. When cleaning the garbage inside the gutter body 3, there is no need to disassemble the entire grate 7. It is only necessary to rotate the grate 7 through the movable rod 10 so that after squeezing and detaching from the restriction of the second flexible plastic block 11, the grate body 3 can be opened, thereby simplifying the subsequent maintenance steps. The opened auxiliary groove 12 increases the force points of the movable rod 10, thereby achieving the purpose of convenient use.
