[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1-Figure 4 As shown, a plastic barrel sealing and covering structure comprises a plastic barrel main body 1, a ring body 4 is installed on the upper end of the plastic barrel main body 1, a discharge port 11 is inserted and connected in the middle of the upper end of the plastic barrel main body 1, the discharge port 11 is used to discharge the material in the plastic barrel main body 1, a screw cover 12 is threadedly sleeved on the outer surface of the discharge port 11, a sealing cover 6 is arranged on the upper end of the ring body 4, an inflation component 8 is installed on the left part of the upper end of the sealing cover 6, a detection component 10 is installed on the rear part of the upper end of the sealing cover 6, and four fixing components 5 distributed in a ring array are arranged between the sealing cover 6 and the ring body 4.

[0028] Two annular grooves 41 are provided at the upper end of the ring body 4 from the inside to the outside, and sealing rings 42 are provided in the two annular grooves 41. The sealing rings 42 are located between the ring body 4 and the sealing cover 6. The two sealing rings 42 are used to enhance the stability and reliability of the connection, ensure that the sealing effect is long-lasting, and is not easily affected by external factors and fails.

[0029] The inflatable component 8 and the sealing cover 6 are used together to improve the sealing performance of the spiral cover 12. The inflatable component 8 includes an air pump 81, which is installed at the upper end of the sealing cover 6. The exhaust end of the air pump 81 is connected to a connecting pipe 82, and the front end of the connecting pipe 82 is connected to a one-way valve 83. The lower end of the one-way valve 83 is inserted and connected to the sealing cover 6. The one-way valve 83 is used to prevent the gas in the sealing cover 6 from returning to the connecting pipe 82.

[0030] Since the gas in the sealing cover 6 will gradually escape, causing the air pressure to drop and the sealing effect to weaken, the detection component 10 can be used to detect the air pressure in the sealing cover 6. The detection component 10 includes a mounting plate 101, which is mounted on the upper rear part of the sealing cover 6. A pressure gauge 103 and a controller 102 are respectively mounted on the upper left and upper right parts of the mounting plate 101. The detection end of the pressure gauge 103 extends into the sealing cover 6. When in use, the pressure threshold of the sealing cover 6 is set by the controller 102, and the pressure gauge 103 detects the pressure of the sealing cover 6. When the pressure is lower than the pressure threshold, the controller 102 controls the air pump 81 to inflate the sealing cover 6 again until the pressure in the sealing cover 6 reaches a certain value. The controller 102 controls the air pump 81 to stop inflating, so that the sealing performance at the screw cover 12 maintains stability and continuity, thereby improving the sealing reliability.

[0031] In order to facilitate opening of the sealing cover 6 , an exhaust valve pipe 9 is inserted and connected to the right portion of the upper end of the sealing cover 6 , and the exhaust valve pipe 9 is used to exhaust the gas in the sealing cover 6 .

[0032] The fixing component 5 is used to fix the sealing cover 6 on the ring body 4. The fixing component 5 includes a first rectangular block 51 and a second rectangular block 52. The first rectangular block 51 and the second rectangular block 52 are respectively installed on the outer surfaces of the ring body 4 and the sealing cover 6. A screw 53 is installed at the upper end of the first rectangular block 51. The upper end of the screw 53 movably passes through the upper side of the second rectangular block 52. A nut 54 is threadedly sleeved on the outer surface of the screw 53.

[0033] The outer surfaces of the air pump 81 and the detection component 10 are covered with a protective shell 7 , which is installed on the upper end of the sealing cover 6 . The protective shell 7 is used to prevent dust from falling on the protective shell 7 and the detection component 10 .

[0034] Two fixing blocks 2 are installed on the left and right outer surfaces of the plastic barrel body 1. A handle 3 is provided between two adjacent fixing blocks 2. The handle 3 is rotatably connected to the fixing blocks 2 via a rotating shaft. The handle 3 is used to drive the plastic barrel body 1 to move.

[0035] The utility model provides a plastic barrel sealing cover structure. When in use, after the sealing cover 6 is fixedly connected to the ring body 4, the exhaust end of the air pump 81 is controlled to fill a certain amount of gas into the sealing cover 6 through the connecting pipe 82 and the one-way valve 83, so that the air pressure in the sealing cover 6 is greater than the external air pressure. The gas pressure can make the spiral cover 12 fit more tightly on the discharge port 11, fill the possible small gap or incompletely sealed place, and the double sealing ring 42 can enhance the stability and reliability of the connection between the sealing cover 6 and the ring body 4, ensure the lasting sealing effect, and the pressure gauge 1 03 can detect the air pressure change of the sealing cover 6. When it is less than the pressure threshold, the pressure gauge 103 transmits a signal to the controller 102. After comparing multiple data, the controller 102 controls the air pump 81 to transport a certain amount of gas into the sealing cover 6 again, so that the sealing performance at the screw cover 12 remains stable and continuous. When the liquid in the plastic barrel body 1 needs to be used, the exhaust valve pipe 9 is opened to discharge the gas in the sealing cover 6, the nut 54 is turned to separate the sealing cover 6 from the ring body 4, and the screw cover 12 is turned to use the liquid in the plastic barrel body 1.
