[0020] 1. By setting a sealing mechanism, the cover body can be closely fitted with the cabinet body, thereby improving the sealing of the cabinet body. By utilizing the cooperation between the steel ball, the limit block and the limit cylinder, the cover body can be closely fitted with the cabinet body in a normal state. By pressing the button, the push rod is driven to move in the groove, thereby releasing the limit of the push rod on the steel ball, and the steel ball can be separated from the limit block, which makes it easy to remove the limit cylinder from the limit block, thereby releasing the limit of the limit cylinder on the cover body, and facilitating the opening of the cover body. By arranging a first spring, the push rod can always be in contact with the steel ball without being subjected to external force. By utilizing the engaging relationship between the steel ball and the limit block, the limit cylinder can be confined in the limit block, thereby improving the closing stability of the cover body. By arranging the first rubber ring and the second rubber ring, the sealing between the limit block and the limit cylinder can be improved.

[0021] 2. By setting up a heat dissipation mechanism, the components inside the cabinet body can be quickly cooled and cooled. The dried cold air is compressed into the distributor through the fan, and then transported to each support plate through the air pipe by the distributor, so that the components on the support plate can be ventilated and cooled. When the air pressure inside the cabinet body is too high, the airflow will squeeze the movable block in the second ventilation duct to move in the direction of the second spring, so that the airflow inside the cabinet body can flow out through the vent, thereby ensuring that the pressure inside and outside the cabinet body is consistent. By utilizing the cooperation between the second spring, the movable block and the second ventilation duct, one-way airflow can be achieved, thereby preventing the components inside the cabinet body from being affected by external humid air.

[0038] Working principle: Before using this shipboard cabinet cover sealing structure, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 7 As shown, when the cover body 103 needs to be opened, the button 110 is first pressed to drive the push rod 106 to move in the groove 105, thereby releasing the limit of the push rod 106 on the steel ball 112, and the steel ball 112 can be separated from the limit block 113, so that the limit cylinder 104 can be easily removed from the limit block 113, thereby releasing the limit of the limit cylinder 104 on the cover body 103, and the cover body 103 can be easily opened;

[0039] Secondly, when it is necessary to perform heat dissipation treatment on the inside of the cabinet body 101, the fan 201 is started to compress the dried cold air into the distributor 203, and then the distributor 203 transports the cold air to each support plate 206 through the air pipe 205, so that the components on the support plate 206 can be ventilated and heat-dissipated. When the air pressure inside the cabinet body 101 is too high, the air flow will squeeze the movable block 210 in the second ventilation pipe 208 to move in the direction of the second spring 209, so that the air flow inside the cabinet body can flow out through the vent 212, thereby ensuring that the pressure inside and outside the cabinet body 101 is consistent.
