Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a powder tank car cover open mouth formula sealing washer, includes lid 1, fills up body 3 and locating part 6, the body 3 is installed to the inner chamber of lid 1, spacing groove 2 has been seted up to the inner wall of lid 1, the spacing ring 4 with 2 looks adaptations of spacing groove is installed to the outer wall that fills up body 3, spacing ring 4 is installed in the inner chamber of spacing groove 2, ring channel 5 has been seted up to the inner wall that fills up body 3, the inner chamber joint of ring channel 5 has locating part 6.

The limiting part 6 comprises a first annular plate 7 and a second annular plate 8, the bottom of the first annular plate 7 is connected with an insertion tube 9, the top of the second annular plate 8 is provided with a lantern ring 10, the bottom of the insertion tube 9 is inserted into an inner cavity of the lantern ring 10 and is connected with a third annular plate 11, and the bottom of the third annular plate 11 is connected with the bottom of the inner cavity of the lantern ring 10 through a spring 12.

In this embodiment (see fig. 2), the first annular plate 7 and the second annular plate 8 have the function of expanding towards two sides through the movable connection of the cannula 9 and the collar 10.

Wherein, the annular groove 5 is a groove matched with the limiting piece 6.

In the present embodiment (see fig. 1), the position limiting member 6 can be effectively limited.

Wherein the first annular plate 7, the second annular plate 8, the cannula 9 and the collar 10 are all concentric with the annular groove 5.

In this embodiment (see fig. 1), the dimensions are matched.

Wherein, the opening width of the annular groove 5 is less than the height of the limiting member 6.

In the present embodiment (see fig. 1), the width of the opening is small, so that the limiting member 6 is prevented from falling off.

When the opening type sealing ring of the powder tank truck cover is used, firstly, the limiting ring 4 is clamped in the limiting groove 2 by utilizing the elasticity of the pad body 3 during installation, then when the cover body 1 and the tank truck are closed, the tank opening can be pressed on the bottom surface of the cover body 1 and the bottom surface of the pad body 3 to be attached and tightly pressed, then when the inner cavity of the tank truck is pressed upwards during use, firstly, the inner cavity top of the pad body 3 is pressed, the two sides of the former pad body have the tendency of inward folding, when the inner side folds, gaps are generated between the bottom end surface of the pad body 3 and the tank opening to seal loosely, when the limiting piece 5 in the annular groove 5 arranged on the inner wall of the pad body 3 receives high pressure, the pressure respectively acts on the first annular plate 7 and the second annular plate 8, at the moment, the first annular plate 7 and the second annular plate 8 respectively have the tendency of moving towards two sides under the action of the pressure, thus, the second annular plate 8 presses the bottom of the cushion body 3, so that the second annular plate is tightly pressed at the can mouth, the sealing effect is improved, and when the pressure is finished, the first annular plate 7 and the second annular plate 8 are reset under the action of the spring 12, so that the cover body 1 is conveniently opened.
