[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] With reference to Figures 1-3 An embodiment provided by the utility model: a metal bellows with sealing structure, comprising a bellows body 1, the left end outer wall of the bellows body 1 is fixedly connected with a connecting ring 2, the outer wall of the connecting ring 2 is provided with a connecting piece 3, a third sealing gasket 14 is arranged between the connecting piece 3 and the connecting ring 2, the left end of the third sealing gasket 14 is fixedly connected to the right end inner wall of the connecting piece 3, the outer wall of the connecting piece 3 and the connecting ring 2 is provided with a sealing ring 8, the inner wall of the sealing ring 8 is fixedly connected with a connecting plate 9 at the front and rear ends, the two side connecting plates 9 are connected by a first bolt 10, the inner wall of the sealing ring 8 is threadedly connected with a second bolt 13, the bottom end of the second bolt 13 corresponds to the top end of a fixed block 6, the outer wall between the sealing ring 8 and the connecting piece 3 is fixedly connected with a first sealing gasket 11, and the outer wall between the sealing ring 8 and the connecting ring 2 is fixedly connected with a second sealing gasket 12.

[0026] Specifically, the third sealing gasket 14 is responsible for closing the gap between the connecting ring 2 and the connecting piece 3 to enhance the sealing effect. Then, the first bolt 10 is rotated, which drives the connecting plate 9 to move, thereby fixing the sealing ring 8. At the same time, the second sealing gasket 12 and the first sealing gasket 11 seal the gap between the sealing ring 8 and the connecting ring 2 and the connecting piece 3 respectively, further improving the sealing effect. The position of the sealing ring 8 can be fixed by the second bolt 13, and the second bolt 13 is in contact with the fixed block 6, preventing the fixed block 6 from moving, thereby enhancing the connection stability between the connecting ring 2 and the connecting piece 3. By arranging the sealing ring 8, the first sealing gasket 11, the second sealing gasket 12 and the third sealing gasket 14, the multiple sealing structure significantly improves the sealing performance of the connecting part of the bellows body 1, effectively avoiding the leakage problem caused by wear or aging of the rubber sleeve after long-term use in the prior art.

[0027] With reference to Figure 1 , Figure 3 and Figure 4The outer side of the inner wall of the connecting piece 3 is fixedly connected with a plurality of slide rods 4, the outer wall of the slide rod 4 is slidably connected with a sliding block 5, one end of the inner side of the sliding block 5 is fixedly connected with a fixed block 6, the fixed block 6 and the inner wall of the connecting piece 3 are connected through a spring 7, one end of the spring 7 is connected with the inner wall of the connecting piece 3, the other end of the spring 7 is connected with the fixed block 6, the bottom end of the right side of the fixed block 6 is arc-shaped, and the left end of the fixed block 6 corresponds to the right end of the connecting ring 2;

[0028] Specifically, when connecting the corrugated pipe body 1, first, the connecting ring 2 is used to sleeve the corrugated pipe body 1 and the connecting piece 3. At this time, the connecting ring 2 extrudes the fixed block 6, so that the fixed block 6 pushes the sliding block 5 to slide along the outer wall of the slide rod 4. At the same time, the fixed block 6 exerts pressure on the spring 7, and the spring 7 deforms after being stressed. When the connecting ring 2 is completely inserted into the connecting piece 3, the spring 7 restores its original shape by virtue of its elasticity, so as to reset the fixed block 6 and exert pressure on the connecting ring 2 to achieve fixation.

[0029] Working principle: when the corrugated pipe body 1 needs to be connected, first, the connecting ring 2 is used to sleeve the corrugated pipe body 1 and the connecting piece 3. At this time, the connecting ring 2 extrudes the fixed block 6, so that the fixed block 6 is extruded and drives the sliding block 5 to slide along the outer wall of the slide rod 4. At the same time, the fixed block 6 extrudes the spring 7, and the spring 7 deforms after being stressed. When the connecting ring 2 is completely inserted into the connecting piece 3, the spring 7 restores its original shape by virtue of its elasticity, so as to reset the fixed block 6 and exert pressure on the connecting ring 2 to achieve fixation.

[0030] At the same time, the third sealing gasket 14 seals the gap between the connecting ring 2 and the connecting piece 3, improves the sealing performance, then the first bolt 10 is rotated, the first bolt 10 drives the connecting plate 9 to move, fixes the sealing ring 8, at the same time, the second sealing gasket 12 and the first sealing gasket 11 respectively seal the gap between the sealing ring 8 and the connecting ring 2 and the connecting piece 3, further improve the sealing performance, the position of the sealing ring 8 can be fixed through the second bolt 13, and the second bolt 13 abuts against the fixed block 6 to prevent the fixed block 6 from shaking, thereby improving the connection stability between the connecting ring 2 and the connecting piece 3. Through the setting of the sealing ring 8, the first sealing gasket 11, the second sealing gasket 12 and the third sealing gasket 14, the multiple sealing structure greatly improves the sealing performance of the connection of the corrugated pipe body 1, and avoids the phenomenon of water leakage caused by easy wear or aging of the rubber sleeve after long-term use in the prior art.

[0031] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
