DETAILED DESCRIPTION

[0023] As Figure 1 and Figures 5-7As shown, it also includes a buffer pad 12, a buffer spring 13, a guide plate 14, an air bag 15, an air bag 16, a cover 17, a handle 18 and a protective screen 19. The inner walls of the left and right sides of the protective frame 1 are provided with storage grooves 11. The inner walls of the two storage grooves 11 are connected by screws with two columns of vertically arranged buffer springs 13. Each column contains four buffer springs 13. The buffer springs 13 on the same side form a group. There are two groups in total. Each group has eight buffer springs 13. The gap space between the storage groove 11 and the buffer spring 13 is filled with a buffer pad 12 by high-strength epoxy structural adhesive. The inner sides of each group of buffer springs 13 are connected by screws with guide plates 14. The top of each guide plate 14 is inwardly circularly chamfered. This helps to guide the display screen 10 to smoothly slide down to the designated position during installation. The inner side of each guide plate 14 is flush with the inner side of the storage groove 11. The inner walls of the left and right sides of the protective frame 1 are symmetrically connected by high-strength epoxy structural adhesive with an air bag 15. The gas inlet end of the air bag 15 faces upwards. The inner wall of the lower side of the protective frame 1 is connected by high-strength epoxy structural adhesive with an air bag 16. The gas inlet end of the air bag 16 faces left. The rear sides of the air bag 15 and the air bag 16 are in close contact with the non-screen parts on the left and right sides of the display screen 10. The top of the protective frame 1 is rotatably connected with a cover 17. The top of the cover 17 is connected by screws with a handle 18. The protective screen 19 is inlaid between the left and right sides and the lower side of the protective frame 1. The protective screen 19 is transparent and made of polycarbonate.

[0024] First, the display screen 10 is installed on the front side of the fixed seat 9. The sliding block 8 is installed on the rear side of the fixed seat 9. It is ensured that the display screen 10 and the sliding block 8 are stably installed. Then, the cover 17 is opened upwards by the handle 18 so that it does not block the top of the protective frame 1. Then, the fixed seat 9 is placed vertically. The clamping seat on the sliding block 8 is precisely clamped with the sliding rail 7. Then, a downward pushing force is applied to the fixed seat 9. This causes the sliding block 8 to drive the fixed seat 9 and the display screen 10 to move downwards along the sliding rail 7 to the limit position. At this time, the display screen 10 has completely entered the inside of the protective frame 1 and is fully protected by its structure. During the downward movement of the display screen 10, its left and right sides will be in close contact with the guide plates 14 on the same side and may exert a squeezing action on the two guide plates 14. When the distance between the left and right sides of the display screen 10 is greater than the distance between the inner sides of the two guide plates 14, the display screen 10 will push the two guide plates 14 outward, thereby compressing the buffer pad 12 and the buffer spring 13. In this process, the buffer pad 12 and the buffer spring 13 will undergo a certain degree of elastic deformation. At the same time, the two guide plates 14 exert a reverse force on the left and right sides of the display screen 10, forming a stable clamping state. This makes the display screen 10 be firmly positioned after installation. Even if it is subjected to external impact, it will not shake violently or shift position. Finally, the cover 17 is reset by the handle 18, thereby completing the entire installation process of the display screen 10.

[0025] When the display screen 10 is hit by external force on both sides, the impact force first acts on the surface of the anti-collision plate 6, and the anti-collision plate 6 transmits the impact force to the abutting plate 5 and the abutting block 4. At this time, the anti-collision plate 6, the abutting plate 5 and the abutting block 4 decompose and disperse the external force through their structural design, absorb part of the impact energy, and effectively reduce the impact on the internal components. At the same time, the hydraulic buffer 3 is also hit by the impact force from the outside; when the external force acts on the hydraulic buffer 3, the internal piston in the cylinder body is displaced, forcing the hydraulic oil to flow through the throttle hole. Due to the incompressible nature of the liquid, the hydraulic oil can only flow slowly through the throttle hole, thereby producing a damping effect, converting impact kinetic energy into heat energy and consuming it, achieving effective buffering of external force; in addition, the hydraulic buffer 3 still has high rigid support ability during the buffering process, and its structural design ensures that it will not deviate or sway during the stress process, thereby maintaining the stability of the display screen 10 main body and further preventing excessive deformation or vibration caused by external force. It is worth noting that on the inclined surface of the base 2 on both sides which is not in contact with the protection frame 1, there is a hydraulic buffer 3 with the same inclination angle. This layout design makes it possible to effectively decompose and absorb external force from any direction, improving the overall impact resistance of the device; air bag one and air bag two simultaneously buffer external force.

[0026] When the display screen 10 is in working condition, its internal components may generate heat during long-term operation, so timely heat dissipation is particularly important. At this time, the rear side of the protection frame 1 and the top of the cover 17 are provided with a plurality of air holes, which can effectively promote air circulation and discharge heat, avoiding the influence of the display screen 10 due to overheating, thereby prolonging its service life; in addition, if there are stains on the surface of the protective screen 19, they can be wiped off with a cleaning cloth or other tools to keep the screen surface clean and ensure clear display content without interference.
