The bottom of the push rod 8 is fixedly connected with a first button 11, and the first button 11 is slidably connected to the shell 1.

[0029] Through the above technical solution, pressing the first button 11 drives the push rod 8 to move upward, compressing the second spring 12. When the push rod 8 moves upward, it drives the first inclined groove 9 to move upward. The inclined surface of the first inclined groove 9 presses against one end of the push rod 10. As the first inclined groove 9 moves upward, the push rod 10 is pushed to one side. When the push rod 10 moves, it presses against the second inclined groove 13 on the outer wall of the block 5. Under the push of the push rod 10, the second inclined groove 13 moves, driving the block 5 to move and compressing the first spring 6.

[0030] Specifically, a sealing cavity 14 is formed on the outer wall of the housing 1 . The sealing cavity 14 is annular in shape. A rubber ring 15 is provided inside the sealing cavity 14 . The interior of the rubber ring 15 is hollow.

[0031] With the above technical solution, the display cover plate 2 is protected around the display cover plate 2 by the provided rubber ring 15 , thereby preventing water vapor from penetrating into the connection between the display cover plate 2 and the housing 1 .

[0032] Specifically, a cavity 18 is provided inside the shell 1 and above the sealed chamber 14. The inner wall of the cavity 18 is slidably connected to a piston plate 19. The top of the piston plate 19 is fixedly connected to a piston rod 20. The top of the piston rod 20 passes through the cavity 18 and is fixedly connected to a second button 21. The piston rod 20 and the second button 21 are both slidably connected to the shell 1. The outer wall of the piston rod 20 is sleeved with a third spring 22. An air inlet groove 23 is provided on the top of the shell 1. The air inlet groove 23 extends to the interior of the cavity 18. A second one-way valve 24 is provided inside the air inlet groove 23. The second one-way valve 24 is opened toward the direction of the cavity 18. An air outlet groove 16 is provided between the cavity 18 and the sealed chamber 14. A first one-way valve 17 is provided inside the air outlet groove 16. The first one-way valve 17 is opened toward the direction of the sealed chamber 14. A hose 25 is connected between the rubber ring 15 and the air outlet groove 16.

[0033] By the above technical solution, after the display cover plate 2 and the housing 1 are installed, the second button 21 is pressed to drive the piston rod 20 to move downward, compressing the third spring 22, so that the piston plate 19 slides downward in the cavity 18. While the piston plate 19 moves downward, it cooperates with the first one-way valve 17 and the second one-way valve 24 to squeeze the air in the cavity 18 into the rubber ring 15 along the air outlet groove 16 and the hose 25, so that the rubber ring 15 is inflated. The second button 21 is released, and under the action of the third spring 22, the second button 21 is moved upward, driving the piston plate 19 to move upward. While the piston plate 19 moves upward, it cooperates with the first one-way valve 17 and the second one-way valve 24 to draw external air into the cavity 18 along the air inlet groove 23. This reciprocating cycle is repeated. As the second button 21 is continuously pressed, the rubber ring 15 continues to expand, not only filling the sealed cavity 14, but also fitting tightly with the display cover plate 2, further preventing water vapor from penetrating the connection between the display cover plate 2 and the housing 1.

[0034] Specifically, a collar 29 is slidably connected to the outer wall of the housing 1 , and magnets 26 are fixedly connected to the sides of the collar 29 and the display cover 2 that are close to each other, and the two magnets 26 attract each other.

[0035] Through the above technical solution, after the display cover plate 2 and the housing 1 are installed, the ring 29 is pushed to move toward the display cover plate 2. After the ring 29 approaches the display cover plate 2, the two magnets 26 attract and connect with each other, so that the ring 29 is fixed on the display cover plate 2.

When the insert block 4 is inserted into the slot 3, the inclined surfaces of the two card blocks 5 are pressed tightly. As the insert block 4 is inserted, the two card blocks 5 are pushed to move one upward and the other downward, pressing the two first springs 6. After the card slot 7 moves to the same vertical plane as the card block 5, the two card blocks 5 are reset at the same time under the action of the two first springs 6 and inserted into the two card slots 7, thereby fixing the insert block 4 in the slot 3 and completing the installation of the display cover 2. When the display cover 2 is installed on the housing 1, the sealing ring 27 is inserted into the sealing groove 28, thereby fixing the display cover 2 and the housing 1. The connection between the display cover 2 and the housing 1 is sealed to prevent water vapor from penetrating into the connection between the display cover 2 and the housing 1. The second button 21 is pressed to drive the piston rod 20 to move downward, compressing the third spring 22 to make the piston plate 19 slide downward in the cavity 18. While the piston plate 19 moves downward, it cooperates with the first one-way valve 17 and the second one-way valve 24 to squeeze the air in the cavity 18 into the rubber ring 15 along the air outlet groove 16 and the hose 25 to inflate the rubber ring 15. The second button 21 is released. Under the action of the third spring 22, the second button 21 moves upward, driving the piston plate 19 to move upward. While the piston plate 19 moves upward, it cooperates with the first one-way valve 17 and the second one-way valve 24 to squeeze the air in the cavity 18 into the rubber ring 15 along the air outlet groove 16 and the hose 25 to inflate the rubber ring 15. The second one-way valve 24 draws external air into the cavity 18 along the air inlet groove 23, and reciprocates thereby. As the second button 21 is continuously pressed, the rubber ring 15 is continuously expanded, not only filling the sealing cavity 14, but also fitting tightly with the display cover plate 2, further preventing water vapor from penetrating into the connection between the display cover plate 2 and the housing 1. After the display cover plate 2 and the housing 1 are installed, the sleeve 29 is pushed to move toward the display cover plate 2. After the sleeve 29 approaches the display cover plate 2, the two magnets 26 attract and connect with each other, fixing the sleeve 29 on the display cover plate 2. The sleeve 29 blocks the connection between the display cover plate 2 and the housing 1, effectively preventing water vapor from entering. When disassembling and repairing the display cover 2, push the collar 29 to separate the collar 29 from the display cover 2, press the first button 11, drive the push rod 8 to move upward, compress the second spring 12, and while the push rod 8 moves upward, it drives the first inclined slot 9 to move upward. The inclined surface of the first inclined slot 9 presses against one end of the push rod 10. As the first inclined slot 9 moves upward, it pushes the push rod 10 to move to one side. While the push rod 10 moves, it presses against the second inclined slot 13 on the outer wall of the card block 5. Under the push of the push rod 10, the second inclined slot 13 moves, driving the card block 5 to move and compressing the first spring 6. After the insert block 4 is out of the limit of the two card blocks 5, it can be easily removed from the slot 3.
