Detailed Description
The utility model is further described with reference to the following figures and detailed description.
As shown in fig. 1, 2 and 3, the sealing cover of the present invention includes an upper cover 1 and a lower cover 2, wherein the rear side of the upper cover 1 is connected with the rear side of the lower cover 2 through a hinge, an upper cover sealing plate 11 is disposed in the upper cover 1, the lower cover 2 includes a sealing inner plate 211 and a sealing outer plate 212, the upper cover sealing plate 11 and the sealing inner plate 211 are in contact to form a first sealing structure, and the sealing outer plate 212 is used for being in contact with a tank sealing plate 31 of the tank 3 to form a second sealing structure.
In order to improve the sealing effect and the service time of the first sealing structure, as shown in fig. 2, the contact portion between the upper cover sealing plate 11 and the sealing inner side plate 211 is arc-shaped.
In order to facilitate the processing of the lower cover 2, the lower cover 2 includes a lower cover body 21 and a lower cover outer 22, the lower cover outer 22 is disposed on the lower cover body 21, and the seal inner plate 211 and the seal outer plate 212 are disposed on the lower cover body 21. In order to ensure and improve the connection firmness of the lower cover body 21 and the lower cover outer ring 22, as shown in fig. 3, a clamping protrusion 213 is disposed on the circumferential direction of the lower cover body 21, a clamping groove 221 is disposed on the circumferential direction of the lower cover outer ring 22, and the clamping protrusion 213 is disposed in the clamping groove 221 in a matching manner.
Through a large number of practices and experiments of the inventor, the sealing performance of the combination of the soft and hard plastic materials is better than that of the combination of the two hard plastic materials.
