[0021] Embodiment 1:

[0022] like Figure 1-Figure 7As shown, the utility model provides a liquid crystal display screen with explosion-proof function, including a chassis 1, the front side of the chassis 1 is an open surface, the top of the chassis 1 is covered with a top cover 2, the front side of the chassis 1 is provided with an assembly rib 3, the assembly rib 3 and the inside of the chassis 1 are fixedly installed with a bearing plate 4, both sides of the bearing plate 4 are extended with connecting members 5, the connecting members 5 include a side plate 6 and a first fixing plate 7, the first fixing plate 7 is provided with an assembly hole 8, the first fixing plate 7 is provided with a convex rib 9 at the side edge of the assembly hole 8, the convex rib 9 is fixedly connected with a transparent protective film 10, the assembly rib 3 is located outside the chassis 1 and is fixedly installed with a tempered glass 12 through an outer frame 11, and the bearing plate 4 is fixedly installed with a display screen 13. A fixing buckle 14 is provided at the bottom of the chassis 1, and the fixing buckle 14 is fixedly connected to the bearing plate 4 through a second fixing plate 15. The side plate 6 is provided with a slot 16. The material of the transparent protective film 10 is polycarbonate. A heat dissipation hole 17 is provided on the back of the chassis 1.

[0023] Through the above technical scheme, the utility model installs a carrying plate 44 inside the chassis 1, a display screen 13 is installed in the carrying plate 4, and a transparent protective film 10 is installed on the connecting piece 5 of the carrying plate 4. The transparent protective film 10 is located between the tempered glass 12 and the display screen 13. The transparent protective film 10 and the display screen 13 have a buffer interval. When the tempered glass 12 is impacted and broken, the transparent protective film 10 effectively blocks the glass fragments from directly damaging the display screen 13, thereby increasing the service life of the display screen 13 and reducing the maintenance cost.

[0024] Embodiment 2:

[0025] like Figure 1-Figure 7As shown, the front side of the chassis 1 is an open surface. The chassis 1 serves as the main structure of the display screen 13. Its material is light steel or high-strength plastic material. A top cover 2 is installed on the top of the chassis 1. The top cover 2 is convenient for installing other components inside the chassis 1. Its material is the same as that of the chassis 1. An assembly rib 3 is extended from the front side of the chassis 1. The rib not only provides installation support for other components, but also enhances the structural stability of the chassis 1. The rib 3 is assembled and a bearing plate 4 is fixedly installed inside the chassis 1. The bearing plate 4 serves as a mounting base for the display screen 13 component, which ensures the stability and flatness of the display screen 13. It can withstand a certain external force impact and plays a role in supporting and protecting the display screen 13. Connectors 5 are extended on both sides of the bearing plate 4. The connecting member 5 plays a connecting role. The bearing plate 4 is fixedly connected to the chassis 1 through its connecting member 5 to ensure the stability of the display screen 13 during use. The connecting member 5 includes a side plate 6 and a first fixed plate 7 The side plate 6 and the first fixed plate 7 are arranged at an angle with each other, and the connection between the two is transitioned by a rounded corner. The first fixed plate 7 is provided with an assembly hole 8, and the first fixed plate 7 is fixedly connected to the chassis 1 through its assembly port. The first fixed plate 7 is provided with a convex rib 9 at the side edge of the assembly hole 8, and the convex rib 9 is fixedly connected with a transparent protective film 10. The height of the convex rib 9 is equal to the thickness of the transparent adhesive film. The transparent adhesive film is provided with a corresponding through hole that is inserted into the convex rib 9, so that the transparent adhesive film is fixed on the first fixed plate 7. The role of the transparent adhesive film is to protect the display screen 13. The principle is that when the tempered glass 12 is impacted and broken, the transparent adhesive film can prevent the glass fragments from directly contacting the display screen 13, and prevent the display screen 13 from being scratched by the glass fragments. The rib 3 is assembled and is located outside the chassis 1 and is fixedly installed with the tempered glass 12 through the outer frame 11. The tempered glass 12 makes the first layer of protection for the display screen 13, and has impact resistance and high light transmittance. The bearing plate 4 is fixedly installed with the display screen 13.

[0026] The bottom of the chassis 1 of the utility model is provided with a fixing buckle 14, which is fixedly connected to the carrier plate 4 through the second fixing plate 15. The fixing buckle 14 further improves the structural connection stability of the carrier plate 4. The fixing buckle 14 is connected with the fixing plate buckle on the carrier plate 4, so that the carrier plate 4 is firmly installed inside the chassis 1. In addition, the fixing buckle 14 is also convenient for installation and maintenance. Through simple operation, users or maintenance personnel can quickly disassemble and reinstall the carrier plate 4 and perform necessary maintenance work, which greatly improves the maintainability and service life of the display screen 13.

[0027] The side plate 6 of the utility model is provided with a slot 16 structure, which solves the problem of connecting the internal wiring of the display screen 13, while also maintaining the integrity and explosion-proof performance of the chassis 1. The slot 16 allows the display wiring to pass through the side plate 6 smoothly through the slot 16 and connect to the display screen 13, thereby realizing signal transmission and power supply. At the same time, the size of the slot 16 is larger than the size of the wiring, which reduces the weight of the carrier plate 4, and at the same time facilitates the needs of wiring operation and maintenance, making the wiring work smoother and more efficient.

[0028] The material of the transparent protective film 10 of the utility model is polycarbonate. As a high-performance thermoplastic, polycarbonate has excellent transparency, heat resistance, impact resistance and dimensional stability. The high transparency of polycarbonate ensures that the transparent protective film 10 will not have any effect on the display effect of the display screen 13. Users can enjoy a clear and bright visual experience, while the visual effect of the display screen 13 is fully protected. In the case of high temperature or strong impact, the polycarbonate material can resist deformation and the heat resistance and impact resistance of polycarbonate provide additional safety for the display screen 13. In the face of high cracking, the display screen 13 is protected from damage. This is particularly important in the case of accidental impact or high temperature environment of the liquid crystal display screen 13. In addition, the dimensional stability of polycarbonate means that the transparent protective film 10 can maintain its shape and size under different environmental conditions, and will not shrink or expand due to temperature changes or other factors, causing light to refract and affect the display effect of the display screen 13. The durability of polycarbonate makes the transparent protective film 10 have a long service life. Even during long-term use, the protective film can maintain its original performance and appearance, providing users with long-lasting protection.

[0029] The back of the chassis 1 of the utility model is designed with a heat dissipation hole 17, and a heat dissipation fan is installed at the heat dissipation hole 17. The hot air entering the chassis 1 flows through the heat dissipation hole 17, reducing the internal temperature of the chassis 1, ensuring the stable operation of the display screen 13 and extending its service life. The heat dissipation hole 17 can effectively promote the air circulation inside the chassis 1, help the heat to be dissipated from the display screen 13 and other internal components, thereby reducing the operating temperature of the device. At the same time, the design of the heat dissipation hole 17 also takes into account the needs of dust and water resistance. The heat dissipation hole 17 will be equipped with a fine filter or other protective measures, which can prevent dust and moisture from entering the chassis 1, and maintain air circulation to achieve a good heat dissipation effect.
