DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] See Figs. 1-3A sealed and anti-loosening pressure vessel comprises a tank body 1 and a sealing cover 2. An annular groove is provided at the lower part of the sealing cover 2, which covers the upper end surface of the tank body. A circular cavity 3 is provided inside the sealing cover 2, and strip cavities 4 are provided on the left and right sides of the circular cavity 3. A rotating shaft 5 is provided in the center of the sealing cover 2, which extends into the circular cavity 3 and has a bearing 6 at the bottom. An eccentric wheel 7 with an elliptical structure is sleeved on the rotating shaft 5, and an elastic latch assembly 8 is provided in the strip cavity 4. A slot 9 is provided on the inner side of the tank body 1, and a sealing gasket 10 is provided in the slot 9. When the eccentric wheel 7 rotates, force is applied to the elastic latch assembly 8, so that the elastic latch assembly 8 is embedded in the slot 9. Specifically, the eccentric wheel 7 is rotated by rotating the pair 5. When the eccentric wheel 7 rotates to a horizontal state, force is applied to the elastic latch assembly 8 so that the elastic latch assembly 8 is embedded in the slot 9 of the tank body 1, thereby achieving fixed installation of the sealing cover. At the same time, under the action of the spring, the elastic latch assembly 8 reacts on the eccentric wheel, and the sealing cover is not easy to loosen; the sealing gasket 10 is made of rubber material to improve the sealing performance.

[0020] See Figs. 2-3 A pair of positioning posts 11 are also provided in the circular cavity 3 to position the rotation direction and angle of the eccentric wheel 7. In the locked state, the positioning posts 11 are used to ensure that the eccentric wheel 7 can rotate into place and apply force to the elastic latch assembly 8; in the unlocked state, the positioning posts 11 are used to prevent the eccentric wheel 7 from rotating excessively.

[0021] In this embodiment, a threaded hole 12 is defined in the eccentric wheel 7, and a through hole is defined longitudinally within the sealing cover 2. A locking bolt 13 is disposed within the through hole. When the eccentric wheel is rotated into position and a force is applied to the elastic latch assembly, the locking bolt 13 engages with the threaded hole 12. Under the action of the positioning column 11, when the eccentric wheel 7 is rotated into position (locked state), the through hole and the threaded hole 12 coincide in center. At this time, the locking bolt 13 is screwed into the threaded hole 12 to secure the eccentric wheel 7, further ensuring that the sealing cover 2 is not easily loosened.

[0022] In this embodiment, a turntable 14 is provided on the top of the rotating shaft 5. The shape of the turntable 14 is consistent with that of the eccentric wheel 7. A handle 15 is provided on the turntable 14. The orientation of the eccentric wheel 7 can be determined by the rotation direction of the turntable 14, thereby facilitating operation; the handle 15 is used to take the sealing cover 2.

[0023] In the embodiment, the elastic latch assembly 8 comprises a sleeve 81, a latch 82 is arranged in the sleeve 81, one end of the latch 82 is provided with a force plate 83, the other end of the latch 82 is provided with a sealing plate 84, a spring 85 is sleeved between the sleeve 81 and the force plate 83, and the sealing plate 84 covers the insertion slot 9. The force plate 83 is used for being contacted with the eccentric wheel 7 and being extruded by the eccentric wheel, so that the latch 82 is forced, the spring 85 is extruded, the latch 82 is moved forward and embedded into the insertion slot 9, and the installation of the sealing cover 2 is realized; when the eccentric wheel 7 is not contacted with the force plate 83, the latch 82 is reset under the action of the spring, the latch 82 exits the insertion slot 9, and the sealing cover is unlocked; the sealing plate 84 is in an arc-shaped structure and is attached to the insertion slot 9, and the sealing performance is further improved.

[0024] The above merely aims to illustrate the technical scheme of the utility model and is not limited, and other modifications or equivalent replacements of the technical scheme of the utility model made by those skilled in the art should be covered in the claim range of the utility model.
