The sealing connector 122 is inserted into the insertion port 121 and seals the edge of the insertion port 121. The sealing connector 122 has a connecting hole 1223 that passes through itself and the insertion port 121.

[0025] Specifically, this utility model relates to a high airtightness display screen, including a housing assembly 10 and a display unit 20. The housing assembly 10 includes a first housing 110 and a second housing 120. The first housing 110 is disposed on the frame and bottom of the display unit 20. The first opening of the first housing 110 faces upwards, while the second opening faces downwards. The edge of the second housing 120 is detachably connected to the edge of the second opening. The second housing 120 covers the second opening and protrudes outwards to form a placement groove, which has a certain space and communicates with the space inside the first housing 110. The display unit 20 is disposed between the first housing 110 and the second housing 120, with its side abutting against the edge of the first opening. This allows the first housing 110 to provide sufficient support for the display unit 20, forming a stable and robust structure. A sealing coating 111 is provided at the joint between the first housing 110 and the second housing 120 to prevent gas and liquid from entering the display screen through gaps. The second housing 120 also has a socket 121 and a sealing connector 122 on its side. The socket 121 is circular, and the shape and size of the sealing connector 122 are adapted to the socket 121. The sealing connector 122 is inserted into the socket 121 and can seal the edge of the socket 121, filling the edge gap. However, the sealing connector 122 is not a completely sealed structure. The sealing connector 122 has a connection hole 1223 in the middle, which passes through the sealing connector 122 and the socket 121. External components can be connected to the internal system by inserting the sealing connector 122 at the socket 121.

[0026] More specifically, the high airtightness display screen involved in this utility model is mainly used in gas stations. It not only provides drivers with information on fuel prices and products but also serves as a display for promotional activities, greatly improving the operational efficiency and service quality of gas stations. A sealing connector 122 is provided at the inlet of the second housing 120 to prevent gasoline from entering the second housing 120 through the inlet 121, thereby effectively preventing gasoline from contacting the internal components of the display screen and avoiding malfunctions such as short circuits.

[0027] The sealing connector 122 includes a sealing part 1221 and a connecting main part 1222. The connecting main part 1222 includes a tubular inner layer 1222a with the connecting hole 1223 inside and a covering outer layer 1222b covering the surface of the tubular inner layer 1222a. The first end of the tubular inner layer 1222a extends axially and protrudes from the covering outer layer 1222b. The sealing part 1221 surrounds the outer periphery of the first end of the tubular inner layer 1222a. The first end of the tubular inner layer 1222a is inserted into the socket 121. The sealing part 1221 abuts against the inner wall of the socket 121. The second end of the tubular inner layer 1222a and the covering outer layer 1222b are located outside the socket 121.

[0028] Specifically, the sealing connector 122 is inserted into the socket 121 and can seal the edge of the socket 121. The number and size of the sealing connector 122 are adapted to the socket 121. The sealing connector 122 includes a sealing part 1221 and a connecting main part 1222. The connecting main part 1222 includes a tubular inner layer 1222a and a covering outer layer 1222b. The tubular inner layer 1222a is cylindrical and has a connecting hole 1223 inside. The covering outer layer 1222b is disposed on the outer surface of the tubular inner layer 1222a. The first end of the tubular inner layer 1222a extends axially and protrudes from the covering outer layer 1222b, and the first end of the tubular inner layer 1222a is inserted into the socket 121. The sealing part 1221 surrounds the first end of the tubular inner layer 1222a and abuts against the inner wall of the socket 121. The sealing part 122a is used to fix the position of the sealing connector 122, so that the sealing connector 122 is stably disposed at the socket 121. The tubular inner layer 1222a also has a second end, and the second end and the covering outer layer 1222b are disposed outside the socket 121.

[0029] Both the outer covering layer 1222b and the sealing part 1221 are prismatic in shape.

[0030] Specifically, the prismatic outer covering 1222b and the sealing part 1221 can better fit the installation tools, and during installation, the entire sealing connector 122 and the socket 121 can be connected more tightly and firmly, better preventing water or gas from entering the display screen.

[0031] The sealing connector 122 is made of plastic.

[0032] Specifically, using plastic as the sealing connector 122 allows for a tighter connection between the sealing connector 122 and the socket 121, better preventing gas ingress. The plastic material is highly elastic; when an external power cord is inserted into the connection hole 1223, the elasticity of the plastic ensures that the sealing connector 122 tightly wraps around the power cord plug. Furthermore, the plastic possesses excellent insulation properties, further ensuring circuit safety.

[0033] The sealing coating 111 is a fluorine-modified polyester nano-coating.

[0034] Specifically, fluorine imparts a unique chemical structure to the coating, giving it extremely strong resistance to organic solvents such as gasoline. In the high-concentration gasoline environment of gas stations, it can withstand gasoline corrosion for extended periods, preventing the sealing coating 111 from swelling, dissolving, or experiencing performance degradation due to contact with gasoline. It maintains a consistently good sealing effect, effectively preventing gasoline from seeping into the display screen.

[0035] The display unit 20 includes a display panel, a glass cover plate 210, and a circuit board 220; the glass cover plate 210 covers the surface of the display panel and abuts against the edge of the first opening; the circuit board 220 is disposed in the placement slot; the display panel and the circuit board 220 are electrically connected.

[0036] Specifically, the display unit 20 includes a display panel, a glass cover 210, and a circuit board 220. The upper surface of the display panel 220 is covered by the glass cover 210, and both are the same size. The edge of the glass cover 210 abuts against the edge of the first opening. The circuit board 220 is installed in a placement slot of the second housing 120 and is electrically connected to the display panel. The placement slot effectively prevents gasoline from seeping into and contacting the circuit board 220, ensuring circuit safety.

[0037] A sealing rubber layer is provided at the contact point between the glass cover plate 210 and the first opening.

[0038] Specifically, a sealing rubber layer is provided at the contact point between the glass cover plate 210 and the first opening. The sealing rubber layer is located in the gap between the edge of the glass cover plate and the edge of the first opening, which can prevent gasoline evaporating in the air from seeping into the display screen through the gap between the display unit 20 and the first housing 110.

[0039] The first housing 110 is provided with reinforcing ribs 112.

[0040] Specifically, the bottom of the first housing 110 is provided with strip-shaped reinforcing ribs 112 on both sides. The reinforcing ribs 112 can build a more robust skeleton for the first housing 110, enhancing its strength and rigidity, so that it can remain intact when subjected to minor impacts, effectively protecting the entire display screen. At the same time, when a large amount of gasoline gas unfortunately seeps into the display screen, the first housing 110 will expand or even deform. The reinforcing ribs 112 can help the first housing 110 better maintain its existing shape.

[0041] The first housing 110 is provided with a handle 113, and the first housing 110 and the handle 113 are threadedly connected.

[0042] Specifically, the bottom of the first housing 110 is provided with one or two handles 113, and the first housing 110 and the handles 113 are threaded together. This design makes it easier and faster for workers to disassemble the first housing 110.

[0043] In summary, this utility model achieves a waterproof and airtight effect by providing a sealing connector 122 at the socket 121, and by also providing a sealing coating 111 and a sealing rubber layer on the display screen.
