Description

Technical Field

[0001] This utility model relates to the technical field of LCD screen protection devices, and in particular to a high-precision LCD screen adaptive protective frame. Background Technology

[0002] The high-precision LCD screen adaptive protective bezel is a protective structure designed around the edge of the high-precision LCD screen with adaptive adjustment function. By integrating multiple sensors, drive mechanisms and control units, the protective bezel can automatically adjust its shape, hardness or buffering performance according to changes in the external environment, the usage status of the display screen and potential physical impact risks. The protective bezel can effectively improve the reliability and safety of the display screen in complex usage environments, providing basic protection and auxiliary functions for high-precision LCD screens. The protective bezel can block external dust, liquid and other contaminants from entering the display screen through its own physical structure, ensuring display effect and screen life. The adaptive characteristics can alleviate the impact force caused by external collisions to a certain extent and reduce the probability of display screen damage.

[0003] A search revealed Chinese patent publication number CN219619864U, which discloses a protective device for a liquid crystal display screen. The device includes a main body with connecting blocks at its four corners. Each connecting block has locking blocks on two sides, and the four locking blocks are arranged in a wrapping manner around the main body. Locking blocks are fixedly installed on all four sides of the main body. The locking blocks are U-shaped, with a locking plate movably installed in the recessed part of each locking block. A hinge is fixedly installed at the bottom of the locking plate, and a horizontal plate is fixedly installed on the hinge. A connecting plate is movably installed between the two horizontal plates. When the locking blocks engage, the two straight plates separate, increasing the distance between the lower ends of the two arc-shaped rods until the locking blocks engage between the two straight plates. The elastic force of springs two and one ensures the stability of the engagement effect of the straight plates with the locking blocks, while avoiding damage caused by clamping. However, in actual use, this device tends to tip over, failing to reduce damage to internal components and screen assemblies, resulting in insufficient impact resistance of the liquid crystal screen bezel. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-precision adaptive protective frame for LCD screens, aiming to improve the problem of insufficient impact resistance of LCD screen frames in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-precision liquid crystal display screen adaptive protective frame, including a protective frame, with protective mechanisms arranged vertically inside the protective frame to improve the impact energy absorption rate; fastening mechanisms arranged vertically outside the protective frame to improve the protective capability of the device; a display control mechanism arranged on the front side inside the protective frame; a heat dissipation mechanism arranged on the front side of the protective mechanism to improve the temperature average of the device; the protective mechanism includes two buffer plates, with the opposite sides of the two buffer plates fixedly connected to the upper and lower sides inside the protective frame; multiple three-dimensional grids fixedly connected to the inner sides of the two buffer plates; damping gel fixedly connected to the outer sides of the multiple three-dimensional grids; a conductive rubber ring fixedly connected to the rear side of the protective frame; a rear cover threadedly connected to the rear side of the protective frame; and multiple spiral bolts rotatably connected to the upper and lower ends of the rear side of the rear cover.

[0006] Through the above technical solution: When the high-precision LCD screen's adaptive protective frame is in operation, the protective mechanism functions when an external impact occurs. The two buffer plates, along with their three-dimensional mesh and damping gel, work together. The structure of the three-dimensional mesh and the characteristics of the damping gel effectively disperse and absorb impact energy, improving the impact energy absorption rate. The fastening mechanism reinforces the protective frame from the outside, further enhancing the overall protective capability of the equipment and preventing deformation and damage to the protective frame under impact. The display control mechanism is responsible for regulating the display function of the LCD screen to ensure normal display. During operation, the heat generated by the equipment is dissipated through the heat dissipation mechanism, improving temperature uniformity and ensuring that the equipment operates at a suitable temperature. The conductive rubber ring on the rear side of the protective frame serves a sealing and conductive function, enhancing the electrical performance and sealing of the equipment. The rear cover is securely connected to the protective frame by a spiral bolt, providing protection while facilitating the inspection and maintenance of the internal equipment.

[0007] As a further description of the above technical solution:

[0008] The fastening mechanism includes multiple anti-collision plates. The inner sides of the multiple anti-collision plates are fixedly connected to the upper and lower outer sides of the protective frame. Two connecting rods are fixedly connected between adjacent top two anti-collision plates and bottom two anti-collision plates. Fixers are slidably connected to adjacent sides of the multiple connecting rods. Multiple fixing holes are opened on the inner sides of the multiple connecting rods. Fixing pins are slidably connected to the top of the multiple fixing holes.

[0009] Through the above technical solution: the fastening mechanism enhances the protective capability. Multiple anti-collision plates are fixed to the upper and lower sides of the outer side of the protective frame. When subjected to external impact, they first disperse the impact force. The connecting rod between the top and bottom anti-collision plates forms a stable frame foundation. When facing impacts of different intensities or when stronger protection is needed, the fixing devices on the sliding connecting rods can be adjusted according to the actual situation. The holes on the fixing devices are aligned with the fixing holes at different positions on the inner side of the connecting rods to flexibly adapt to different protection needs. After alignment, the fixing pins are inserted into the fixing holes corresponding to the fixing devices. Through the locking action of the fixing pins, the fixing devices and connecting rods are tightly connected, thereby firmly combining the anti-collision plates and the protective frame, enhancing the overall strength of the frame, and effectively resisting external impacts.

[0010] As a further description of the above technical solution:

[0011] The outer sides of the plurality of spiral bolts all penetrate the interior of the rear cover, and the front sides of the plurality of spiral bolts are rotatably connected to the upper and lower rear ends of the protective frame. The outer side of the conductive rubber ring is fixedly connected between the adjacent parts of the protective frame and the rear cover.

[0012] The above technical solution allows for the following: When installing or maintaining a high-precision LCD screen, multiple spiral bolts penetrate the back cover on the outside and are rotatably connected to the upper and lower ends of the rear side of the protective frame. By rotating the spiral bolts, the back cover can be moved closer to or away from the protective frame along the axis of the spiral bolts. During the closing process, the conductive rubber ring is deformed by the pressure of the protective frame and the back cover, filling the gap between them. It forms a physical seal through its own elasticity, preventing dust and liquid from entering. On the other hand, it utilizes its conductive properties to build an electrostatic discharge path, preventing the accumulation of static electricity from affecting the performance of the display screen. When maintenance is required, the spiral bolts are rotated in the opposite direction to separate the back cover, and the conductive rubber ring returns to its original shape, facilitating quick disassembly.

[0013] As a further description of the above technical solution:

[0014] The display control mechanism includes a protective frame, the outer side of which is fixedly connected to the inner front side of the protective frame. Limiting plates are fixedly connected to the left and right sides of the outer side of the protective frame. Slots are provided on the left and right sides of the inner side of the protective frame. A display panel is fixedly connected to the front side of the protective frame. A control component is provided on the rear side of the protective frame.

[0015] Through the above technical solution: the display control mechanism achieves stable operation and functional regulation of the display screen through structural collaboration. The protective frame is fixed inside the front of the protective frame, and the left and right limiting plates are embedded in the slots of the protective frame to form precise positioning and mechanical fixation, ensuring that the display panel is installed firmly. As a display component, the display panel is supported by the protective frame and exposed on the front, responsible for image output. The rear control component is electrically connected to the display panel, receives external signals in real time and converts them into display commands, and regulates the pixel emission color, brightness and refresh rate parameters. When the device is impacted, the protective frame disperses the impact force to the protective frame through the locking structure of the limiting plates and slots, avoiding direct damage to the display panel. The control component is doubly protected by the protective frame and the protective frame, ensuring stable signal transmission.

[0016] As a further description of the above technical solution:

[0017] The outer side of the limiting plate is fixedly connected to the inner side of the display panel, and the upper and lower sides of the protective frame are both fixedly connected to the opposite side of the buffer plate.

[0018] Through the above technical solution: the display control mechanism achieves stable display and impact protection through multi-layer structure collaboration. The outer side of the limiting plate is fixedly connected to the inner side of the display panel, forming direct support for the display panel. The design of embedding the protective frame slot achieves lateral positioning and prevents the display panel from swaying left and right. The upper and lower sides of the protective frame are fixedly connected to the buffer plate, which rigidly connects the display control mechanism and the protection mechanism. When an external impact is applied to the protective frame, the buffer plate absorbs the impact energy first through the three-dimensional mesh and damping gel. At the same time, the remaining impact force is evenly distributed to the locking structure of the limiting plate and the slot through the protective frame, avoiding deformation or breakage of the display panel due to local stress. The control components are installed on the rear side of the protective frame, and the protective frame and the buffer plate form a double physical protection. With the sealing effect of the conductive rubber ring, dust and moisture are prevented from entering.

[0019] As a further description of the above technical solution:

[0020] The control component includes a mounting plate, the front side of which is connected to the rear side of the protective frame. Multiple connecting plates are fixedly connected to the inner side of the mounting plate, and a controller is fixedly connected to each adjacent side of the multiple connecting plates.

[0021] Through the above technical solution: the control component achieves precise control of the display panel through a structured design. The front side of the mounting plate is connected and fixed to the rear side of the protective frame. The connection between the protective frame and the buffer plate forms mechanical protection, ensuring stable installation of the component. Multiple connecting plates inside the mounting plate are arranged in an array, providing rigid support and electrical connection carrier for the controller. When running, external signals are transmitted to the controller via cables. The controller decodes, calculates, and logically processes the signals, converting them into pixel driving instructions. These instructions are then transmitted to the driver chip of the display panel through conductive lines within the connecting plates. The buffer plate of the protection mechanism absorbs external impacts through a three-dimensional mesh and damping gel, preventing displacement or circuit breakage of the mounting plate and controller due to vibration. The anti-collision plate and connecting rod of the fastening mechanism enhance the overall structural rigidity. Combined with the sealing effect of the conductive rubber ring, a stable working environment is provided for the controller, ensuring the accuracy of signal processing and transmission, ultimately achieving the high-precision display function of the LCD screen.

[0022] As a further description of the above technical solution:

[0023] The heat dissipation mechanism includes two positioners, the rear sides of which are fixedly connected to the top front side of the rear cover. Ventilation frames are fixedly connected to the inner sides of the two positioners, and fans are fixedly connected to the inner sides of the two ventilation frames.

[0024] Through the above technical solution: the heat dissipation mechanism achieves uniform equipment temperature through active ventilation design. Two positioners are fixed to the top front side of the rear cover, providing an installation benchmark for the ventilation frame and ensuring that the fan position is accurately aligned with the heat source area inside the protective frame. When the equipment generates heat during operation, the fan is powered on and rotates at a preset speed, forming an airflow channel within the ventilation frame. The fan draws in hot air from the protective frame and exhausts it to the external environment through the ventilation frame. At the same time, external cold air enters through the gap between the protective frame and the display panel, forming an air circulation. Although the buffer plate and three-dimensional mesh of the protective mechanism have a certain degree of heat insulation, the forced convection of the fan can quickly remove the heat generated by the display panel and controller components, avoiding local overheating. The frame structure formed by the anti-collision plate and connecting rod of the fastening mechanism can reduce the vibration transmission during fan operation, ensuring the stable operation of the heat dissipation system. The sealing performance of the conductive rubber ring prevents dust from entering the equipment with the airflow, ensuring heat dissipation efficiency and equipment reliability. Finally, continuous air convection achieves uniform temperature and extends the service life of the LCD screen.

[0025] As a further description of the above technical solution:

[0026] A dustproof net is fixedly connected to the inner rear side of the protective frame, and multiple air passage slots are fixedly connected to the inner side of the dustproof net. Multiple air outlet slots are opened on the inner top side of the rear cover. An installation slot is opened on the outer left front side of the protective frame, and multiple buttons are fixedly connected to the inner side of the installation slot.

[0027] Through the above technical solution: the dustproof net inside the rear of the protective frame covers the ventilation path, and the air duct guides the airflow through in an orderly manner. When the fan starts, hot air is filtered by the dustproof net and flows to the top through the air duct, preventing dust from entering the core of the equipment with the airflow. The air outlet duct on the top of the inner side of the rear cover is aligned with the ventilation frame to form a hot air exhaust channel, achieving complete circulation. The button in the mounting slot is electrically connected to the control component, which can manually adjust the start / stop or speed of the fan. When the equipment temperature is low, the button controls the fan to run at low speed or standby to reduce energy consumption. When the temperature rises, the button triggers the fan to run at high speed to enhance heat dissipation efficiency. The structural rigidity of the fastening mechanism and the protective mechanism ensures that the dustproof net and air duct components do not shift under vibration. The conductive rubber ring works with the dustproof net to further block the intrusion of external dust, improving the environmental adaptability and working stability of the high-precision LCD screen.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, a multi-level buffer structure is realized that can efficiently absorb impact energy of different directions and intensities, minimize the direct damage of impact force to the display screen, improve the frame's ability to absorb impacts from different directions, effectively reduce the risk of impact damage to the LCD screen, extend the service life of the display screen, provide more reliable protection for the equipment in complex operating environments, and ensure the stable operation of the display screen.

[0030] 2. In this utility model, a tight connection between the protective frame and the installation position is achieved, which effectively improves the stability and flexibility of the installation of the adaptive protective frame of the high-precision LCD screen. It can not only adapt to the installation needs of different scenarios, but also disperse and buffer the impact force when the screen is hit by a collision, greatly reducing the risk of damage to the screen due to collision and extending its service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a high-precision LCD screen adaptive protective frame, including a protective frame 1, which provides basic frame support for the entire protective frame and protects the internal structure of the device. The protective frame 1 has protective mechanisms 2 installed at the top and bottom inside, which improve the impact energy absorption rate and enhance the protection capability of the display screen. The protective mechanism 2 includes two buffer plates 201, which absorb external impact forces and reduce the impact on the display screen. The two buffer plates 201 are fixedly connected to the upper and lower sides of the protective frame 1 on opposite sides, achieving stable installation of the buffer plates 201 within the protective frame 1. Multiple three-dimensional grids 202 are fixedly connected to the inner sides of the two buffer plates 201, further dispersing the impact force and improving the buffering effect.

A conductive rubber ring 204 is fixedly connected to the rear side of the protective frame 1, which serves to conduct electricity and seal, preventing electromagnetic interference and the ingress of dust and moisture. A rear cover 205 is threadedly connected to the rear side of the protective frame 1 to close the rear side of the protective frame 1 and provide protection for the internal components. Multiple spiral bolts 206 are rotatably connected to the upper and lower ends of the rear side of the rear cover 205. They are used to firmly fix the rear cover 205 to the protective frame 1 to ensure the stability of the connection. The outer sides of the multiple spiral bolts 206 all penetrate the interior of the rear cover 205 to achieve the connection between the spiral bolts 206, the rear cover 205, and the protective frame 1. The front sides of the multiple spiral bolts 206 are rotatably connected to the protective frame 1. At the rear top and bottom ends, conductive rubber rings 204 are fixedly connected between the adjacent protective frame 1 and the rear cover 205 to ensure the sealing and electromagnetic shielding effect at the connection point. Fastening mechanisms 3 are provided on the upper and lower exterior of the protective frame 1 to improve the equipment's protective capability and enhance the connection stability between the protective frame and the display screen. A display control mechanism 4 is provided on the front interior side of the protective frame 1 to control and protect the normal operation of the display screen. The display control mechanism 4 includes a protective frame 401 to support and protect the display panel 403, preventing damage from external forces. The outer side of the protective frame 401 is fixedly connected to the front interior side of the protective frame 1, enabling the fixed installation of the protective frame 401 within the protective frame 1. Limit plates 402 are fixedly connected to the left and right exterior sides of the protective frame 401 to limit... To prevent the display panel 403 from shifting, the protective frame 1 has slots 404 on its left and right sides inside, which cooperate with the limiting plate 402 to further fix the position of the display panel 403. The display panel 403, which is the display part of the liquid crystal display screen, is fixedly connected to the front of the protective frame 401 for displaying images and information. The outer side of the limiting plate 402 is fixedly connected to the inner side of the display panel 403 to ensure a stable connection between the display panel 403 and the protective frame 401. The upper and lower sides of the protective frame 401 are fixedly connected to the opposite side of the buffer plate 201, which further protects the display panel 403 from impact. A control component 405 is provided on the rear side of the protective frame 401 to control the operation of the display panel 403 and realize the various functions of the display screen.The control component 405 includes a mounting plate 4051 for mounting and fixing the connecting plate 4052 and the controller 4053, providing a mounting base. The front side of the mounting plate 4051 is connected to the rear side of the protective frame 401, realizing the connection between the control component 405 and the display control mechanism 4. Multiple connecting plates 4052 are fixedly connected to the inner side of the mounting plate 4051, which are used to connect and fix the controller 4053 to ensure the stable operation of the controller 4053. Controllers 4053 are fixedly connected to adjacent sides of the multiple connecting plates 4052 for controlling the display content and working status of the display panel 403. A heat dissipation mechanism 5 is provided on the front side of the protective mechanism 2. To improve the average temperature of the equipment and ensure its operation at a suitable temperature, the heat dissipation mechanism 5 includes two positioners 501, which are used to fix the positions of the ventilation frame 502 and the fan 503, ensuring the stable installation of the heat dissipation mechanism 5. The rear sides of both positioners 501 are fixedly connected to the top front side of the rear cover 205, achieving a fixed installation of the positioners 501. The inner sides of both positioners 501 are fixedly connected to the ventilation frame 502, which guides airflow and provides installation space for the fan 503. The inner sides of both ventilation frames 502 are fixedly connected to the fan 503, which accelerates the dissipation of heat inside the equipment by forcing airflow, thus achieving the heat dissipation function.

[0040] Specifically, when the high-precision LCD screen's adaptive protective frame is in operation, the protective frame 1 provides support for the protective frame, protecting the internal structure of the equipment. If the screen is subjected to external impact, the protective mechanism 2 takes effect first. The buffer plate 201 absorbs the external impact force, reducing the direct impact on the screen. The three-dimensional mesh 202 further disperses the impact force, while the damping gel 203 absorbs and dissipates the energy generated by the impact force. At the same time, the conductive rubber ring 204 provides conductivity and sealing, preventing electromagnetic interference and the entry of dust and moisture. The rear cover 205 is firmly connected to the protective frame 1 by the screw bolt 206, sealing the rear side and protecting the internal components. The fastening mechanism 3 improves the connection stability between the protective frame and the screen, enhancing the overall protection capability. In the display control mechanism 4, the protective frame... 401 supports and protects the display panel 403. The limiting plate 402 cooperates with the slot 404 to limit the position of the display panel 403 and prevent it from shifting. The mounting plate 4051 in the control component 405 provides a mounting base for the connecting plate 4052 and the controller 4053. The connecting plate 4052 fixes the controller 4053. The controller 4053 controls the display content and working status of the display panel 403. During the operation of the equipment, the heat dissipation mechanism 5 starts to work. The positioner 501 fixes the position of the ventilation frame 502 and the fan 503. The ventilation frame 502 guides the air flow. The fan 503 accelerates the dissipation of heat inside the equipment by forcing air flow, ensuring that the equipment works at a suitable temperature and realizing adaptive protection and stable operation of the high-precision LCD screen.

[0041] Reference Figure 1 and Figure 2 The fastening mechanism 3 includes multiple anti-collision plates 301. These plates act as buffers when the display screen is subjected to external impacts, effectively reducing damage to the display screen. The inner sides of the multiple anti-collision plates 301 are fixedly connected to the upper and lower outer sides of the protective frame 1, achieving a stable connection between the anti-collision plates 301 and the protective frame 1, enhancing the stability of the overall protective structure. Two connecting rods 302 are fixedly connected between adjacent top two anti-collision plates 301 and bottom two anti-collision plates 301. The connecting rods 302 connect the anti-collision plates 301, ensuring the positional fixation and structural strength of the anti-collision plates 301. Each adjacent side of the connecting rod 302 is slidably connected to a retainer 303. The retainer 303 can slide on the connecting rod 302, which is convenient for position adjustment according to the size of the display screen and to adapt to different specifications of display screens. Multiple fixing holes 304 are opened on the inner side of multiple connecting rods 302. The fixing holes 304 provide installation positions for fixing pins 305, which facilitates the positioning of the retainer 303. The top of each fixing hole 304 is slidably connected to a fixing pin 305. After the fixing pin 305 is inserted into the fixing hole 304, the retainer 303 can be fixed on the connecting rod 302 to ensure the connection stability of the fastening mechanism 3.

[0042] Specifically, when the display screen is subjected to an external collision, the anti-collision plate 301 in the fastening mechanism 3 first functions, absorbing the impact force generated by the collision through its own structural characteristics, effectively buffering the external force and reducing damage to the display screen. The inner side of the anti-collision plate 301 is fixedly connected to the upper and lower outer sides of the protective frame 1, so that when the anti-collision plate 301 is subjected to impact force, it can distribute the force to the protective frame 1, enhancing the stability of the overall protective structure. The two top anti-collision plates 301 and the two bottom anti-collision plates 301 are fixedly connected by two connecting rods 302, ensuring that the positions of the anti-collision plates 301 are fixed, further improving the structural strength, and enabling the anti-collision plates 301 to work together when subjected to force. The multiple connecting rods 302 are in phase. The fastener 303 is slidably connected to the adjacent side. When it is necessary to fasten the display screens of different specifications, the position of the fastener 303 can be adjusted by sliding on the connecting rod 302 according to the size of the display screen. After the position is adjusted, since multiple fixing holes 304 are opened on the inner side of multiple connecting rods 302, the fixing holes 304 provide the installation position for the fixing pins 305. The fixing pins 305 are slid into the fixing holes 304 from the top and inserted into the fixing holes 304, so that the fastener 303 can be firmly fixed on the connecting rod 302. This ensures that the fastening mechanism 3 maintains the stability of the connection after being adapted to different display screens, effectively protecting the display screens of different specifications, and minimizing the damage to the display screen in the event of a collision.

[0043] Reference Figure 1 , Figure 3 and Figure 5The protective frame 1 has a dustproof net 6 fixedly connected to the rear inside, which can effectively block dust from entering and prevent dust from accumulating on the display screen and related components, affecting the display effect and equipment performance. The dustproof net 6 has multiple air passage slots 7 fixedly connected to the inside, which helps to guide air circulation, making heat dissipation more efficient and enhancing the heat dissipation capacity of the equipment. The rear cover 205 has multiple air outlet slots 8 on the top inside, which can allow hot air to be discharged smoothly, maintain the internal temperature of the equipment and ensure the normal operation of the equipment. The protective frame 1 has a mounting slot 9 on the front left side outside, which is used to install specific components or accessories, facilitating the functional expansion of the equipment. The mounting slot 9 has multiple buttons 10 fixedly connected to the inside, which can realize the corresponding function control of the equipment through the operation of the buttons 10, providing users with a convenient operation method.

[0044] Specifically, during equipment operation, the dustproof net 6 fixedly connected to the rear side inside the protective frame 1 serves as the first line of protection. Through its fine mesh structure, it effectively blocks external dust from entering the equipment, preventing dust accumulation on the display components and avoiding impact on display quality and equipment performance. Multiple air ducts 7 fixedly connected to the inner side of the dustproof net 6 guide airflow within the equipment, accelerating heat transfer and allowing the heat generated during equipment operation to be quickly carried away by the air. Multiple air outlet ducts 8 opened on the top inner side of the rear cover 205 provide an efficient exhaust channel for the air carrying heat. The hot air is smoothly discharged to the outside of the equipment through the air outlet ducts 8, thereby maintaining a stable internal temperature and ensuring normal operation of the equipment. The mounting slot 9 opened on the front left side of the outer side of the protective frame 1 allows for the installation of specific components or accessories according to the equipment's functional expansion needs, enriching the equipment's functionality. Multiple buttons 10 fixedly connected to the inner side of the mounting slot 9 allow users to trigger corresponding circuit signals by operating the buttons 10, thereby controlling the equipment's functions and providing a convenient operating experience.

[0045] Working principle: When the high-precision LCD screen adaptive protective frame is working, the protective frame 1 provides support for the protective frame. If the screen is impacted, the protection mechanism 2 is activated, the buffer plate 201 absorbs the impact force, the three-dimensional grid 202 disperses the force, the damping gel 203 consumes energy, the conductive rubber ring 204 conducts a conductive seal, and the back cover 205 is connected to the protective frame 1 by the spiral bolt 206 to protect the internal components. The fastening mechanism 3 enhances the connection stability. In the display control mechanism 4, the protective frame 401 supports the display panel 403, the limit plate 402 and the slot 404 cooperate to prevent displacement, the mounting plate 4051 of the control component 405 provides a foundation for the connecting plate 4052 and the controller 4053, and the controller 4053 controls the display panel 403. When the equipment is running, the positioner 501 of the heat dissipation mechanism 5 fixes the ventilation frame 502 and the fan 503. The ventilation frame 502 guides the airflow, and the fan 503 forces heat dissipation to ensure stable operation of the equipment.

[0046] Furthermore, when the display screen is subjected to external impact, the anti-collision plate 301 of the fastening mechanism 3 absorbs the impact force through its structure, buffers the external force to reduce damage to the display screen. The inner side of the anti-collision plate 301 is fixed to the upper and lower sides of the outer side of the protective frame 1, distributing the force to the protective frame 1 to enhance stability. The top and bottom anti-collision plates 301 are fixed by two connecting rods 302 to ensure fixed position and improve structural strength, so that the anti-collision plates 301 can work together to bear the force. Multiple connecting rods 302 are slidably connected to the fixing device 303 on adjacent sides, and their positions can be adjusted according to the size of the display screen.
