[0024] Referring to Figure 6, the display window assembly 5 includes a touch screen 501, a wear-resistant layer 502 is bonded to the top of the touch screen 501, an antibacterial and anti-fouling layer 503 is bonded to the surface of the wear-resistant layer 502, and a superhydrophobic coating film 504 is bonded to the surface of the antibacterial and anti-fouling layer 503.

[0025] As a technical optimization of this utility model, the wear-resistant layer 502 protects the screen from scratches and extends its service life. The antibacterial and anti-fouling layer 503 inhibits bacterial growth and reduces stain adhesion, making it suitable for high-hygiene scenarios such as medical and food industries. The superhydrophobic coating film 504 causes liquids to form droplets on the surface and roll off, preventing water stains from affecting touch sensitivity and also assisting in waterproofing.

[0026] Referring to Figures 1, 3, and 4, the mounting component 6 includes four threaded frames 601, which are fixed at the four corners of the mounting groove 2. Sealing bolts 602 are threadedly connected to the four corners of the cover 7, and the sealing bolts 602 are threadedly connected to the threaded frames 601. Multiple fixing frames 603 are fixedly connected to the bottom of the mounting groove 2, and the multiple fixing frames 603 are located between every two threaded frames 601. A cross-shaped positioning groove is opened on the top of the fixing frame 603. Multiple cross-shaped positioning strips 604 are fixedly connected to the bottom of the cover 7, and the positioning strips 604 are engaged with the positioning grooves.

[0027] As a technical optimization of this utility model, the cross-shaped snap-fit ​​structure between the positioning strip 604 and the positioning groove ensures that the cover 7 is accurately positioned during installation, avoiding deviation that could lead to sealing failure. The threaded connection between the sealing bolt 602 and the threaded frame 601 provides high-strength fixation. Combined with the sealing rubber gasket 11, this enhances the stability and sealing performance of the waterproof structure.

[0028] Referring to Figures 3 and 5, four mutually symmetrical anti-fooling posts 12 are fixedly connected to the inner wall of the mounting frame 3, and four mutually symmetrical anti-fooling grooves 13 are opened on the surface of the touch screen component 4, and the anti-fooling grooves 13 are engaged with the anti-fooling posts 12.

[0029] As a technical optimization of this utility model, by matching the shapes of the anti-foolproof post 12 and the anti-foolproof groove 13, it is ensured that the touch screen component 4 is uniquely and correctly installed in the mounting frame 3, avoiding touch failure or poor sealing due to incorrect orientation, and without the need for additional markings or tools, thus improving production efficiency.

[0030] Referring to Figures 3 and 4, a support frame 14 is fixedly connected to the outer side of the mounting groove 2, and the support frame 14 is used in conjunction with the cover 7. A groove 15 is fixedly connected to the bottom of the cover 7, and a protrusion 16 is fixedly connected to the top of the support frame 14, and the protrusion 16 is engaged with the groove 15.

[0031] As a technical optimization of this utility model, the secondary mechanical limiting is formed by the snap-fit ​​of the convex frame 16 and the groove 15, which further reduces the gap between the cover 7 and the bottom shell 1, improves the waterproof level, and the bearing frame 14 disperses the external force on the cover 7, such as the pressure when pressing the screen, to avoid excessive local force that could cause deformation of the sealing structure.

[0032] Referring to Figures 4 and 5, sealing grooves 17 are provided at the top and bottom of the snap-fit ​​groove 8, and sealing strips 18 are fixedly connected to the top and bottom of the snap-fit ​​frame 9, and the sealing strips 18 are snap-fitted with the sealing grooves 17.

[0033] As a technical optimization of this utility model, the sealing strip 18 is embedded in the sealing groove 17 to form an elastic sealing interface. Even if the equipment vibrates or expands and contracts due to heat, it can still maintain a tight fit and prevent liquid penetration. Special sealing is performed on the contact gap between the snap-fit ​​frame 9 and the snap-fit ​​groove 8 to make up for the gap defects of the mechanical snap-fit ​​itself and achieve the dual protection of "mechanical fixation + elastic sealing".

[0034] The working principle and usage process of this utility model are as follows: When installing the touch screen, first fix the mounting frame 3 in the mounting groove 2 at the top of the bottom shell 1.
