According to the glass fiber reinforced plastic connecting structure provided by the embodiment, the press block 3 positioned on one surface of the joint of the first glass fiber reinforced plastic component 1 and the second glass fiber reinforced plastic component 2 and the first sealing layer 5 and the second sealing layer 6 positioned on two surfaces of the joint of the first glass fiber reinforced plastic component 1 and the second glass fiber reinforced plastic component 2 are arranged, so that the connecting strength between the two glass fiber reinforced plastic components is improved, and meanwhile, the sealing performance of the glass fiber reinforced plastic connecting structure is also improved due to the existence of the first sealing layer 5 and the second sealing layer 6; in addition, the first sealing layer 5 and the second sealing layer 6 are flush with the surfaces of the first glass fiber reinforced plastic component 1 and the second glass fiber reinforced plastic component 2, so that the whole glass fiber reinforced plastic connecting structure is smoother and more attractive in appearance.

Because the thick-wall glass fiber reinforced plastic has larger weight compared with the common glass fiber reinforced plastic, the structural stability requirement is higher, the common glass fiber reinforced plastic connecting structure in the prior art cannot provide the required connecting strength, and the glass fiber reinforced plastic connecting structure in the invention has high strength and good sealing property, and can meet the connecting requirement of the thick-wall glass fiber reinforced plastic assembly.
in order to facilitate the connection between the first glass fiber reinforced plastic component 1 and the second glass fiber reinforced plastic component 2 and to make the appearance of the glass fiber reinforced plastic connection structure more beautiful, the present embodiment is further improved as follows, as shown in fig. 1, a first connection arm 7 and a second connection arm 8 are respectively arranged at the connection position of the first glass fiber reinforced plastic component 1 and the second glass fiber reinforced plastic component 2, the first connection arm 7 and the second connection arm 8, the first glass fiber reinforced plastic component 1 and the second glass fiber reinforced plastic component 2, and the side walls of the first glass fiber reinforced plastic component 1 and the second glass fiber reinforced plastic component 2 form a groove body, and the groove body is used for placing the pressing block 3. By the arrangement method, the surfaces of the press block 3, which are far away from the first connecting arm 7 and the second connecting arm 8, are lower than the corresponding surfaces of the first glass fiber reinforced plastic component 1 and the second glass fiber reinforced plastic component 2, so that the sealing of the first sealing layer 5 is facilitated.
In the present embodiment, the compact 3 is preferably trapezoidal, and the cross section of the groove is preferably an inverted trapezoidal groove in consideration of the shape of the compact 3 and the convenience of putting in and taking out the compact 3.

In order to make the first sealing layer 5 flush with one surface and the second sealing layer 6 flush with the other surface, the thickness of the compact 3 should be less than the depth of the tank, and a first groove for accommodating the first sealing layer 5 has been formed. In addition, the surfaces of the first connecting arm 7 and the second connecting arm 8, which are far away from the pressing block 3, are provided with grooves, and the grooves of the first connecting arm 7 and the second connecting arm 8 form a second groove for containing the second sealing layer 6. By the arrangement, the first sealing layer 5 is positioned in the first groove, the second sealing layer 6 is positioned in the second groove, and the thickness of the sealing layers can be adjusted by adjusting the depth of the grooves. The sealing layer is preferably a glass fiber reinforced plastic film, but it will be understood by those skilled in the art that any film that can perform a sealing function can be used as the sealing layer in the present invention.
