Description

Technical Field

[0001] The utility model relates to the technical field of display screen equipment, in particular to a sealed dustproof liquid crystal display screen. Background Art

[0002] Liquid crystal display (LCD) is a flat panel display device that uses liquid crystal material as a display medium. Its working principle is to fill liquid crystal material between two parallel glass substrates and change the arrangement of liquid crystal molecules by applying voltage, thereby controlling the degree of light transmission to display different images. Liquid crystal display has the characteristics of being thin, light, low power consumption, and radiation-free, and is widely used in a variety of electronic devices such as televisions, computer monitors, mobile phones, and tablet computers.

[0003] After searching, the Chinese patent application number is: CN201811207356.7. A liquid crystal display screen includes a wall, a protection box, a locking mechanism, a supporting mechanism, a traction mechanism, a heat dissipation mechanism and a limit ring. The invention can realize the rotation of the display screen to a vertical state, so that maintenance personnel can easily disassemble and repair the back of the display screen without removing the entire display screen. After the maintenance is completed, it can be automatically rotated upward and reset under the drive of the torsion spring, which is convenient and quick without climbing. The locking mechanism can further lock and limit the display screen in the horizontal and vertical states, making it more convenient for workers to operate and enhancing the stability of the display screen installation. The protection box adopts a two-side exhaust design to avoid the wall from blocking the airflow and ensure the heat dissipation effect. The S-shaped exhaust channel can also reduce the entry of external dust, making the inside of the protection box cleaner and less dust collected.

[0004] In the above technical solution, an S-shaped exhaust duct is provided to reduce dust entry, but the sealing of the display screen is still poor. Moreover, once there is too much dust inside the S-shaped exhaust duct, it will not only affect the heat dissipation of the equipment, but also increase the difficulty of cleaning. Therefore, we need to propose a sealed and dustproof LCD display screen. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] A sealed dustproof liquid crystal display screen, comprising:

[0028] Main structure; the main structure includes a display screen body 1 and a housing 2, the display screen body 1 is installed in the housing 2, a bracket 3 is provided at the bottom of the housing 2, and a base 4 is connected to the lower end of the bracket 3;

[0029] The outer wall of the shell 2 is provided with heat dissipation grooves 5, which are arranged in a long strip shape. There are multiple groups of heat dissipation grooves 5 evenly distributed on the shell 2. The inner wall of the shell 2 is clamped with a dustproof mesh plate 6, which can cover and shield all the heat dissipation grooves 5 when the dustproof mesh plate 6 is clamped.

[0030] Specifically, an inspection notch is provided on the housing 2, and a door panel 7 is provided in the notch. One end of the door panel 7 is hinged to one side of the notch, and the other end of the door panel 7 is fixed to the other side of the notch by a fixing screw. A heat dissipation groove 5 is provided on the door panel 7, and a dustproof mesh plate 6 is clamped on the inner wall of the door panel 7. A U-shaped strip 8 is provided on the inner wall of the door panel 7 around the heat dissipation groove 5, and a clamping slot 9 for inserting the dustproof mesh plate 6 is provided on the U-shaped strip 8. An ear seat 12 is symmetrically provided on one side of the door panel 7, and a through hole 13 for the fixing screw to pass through is provided on the ear seat 12, and a screw hole 14 corresponding to the through hole 13 is provided on the housing 2.

[0031] By setting an inspection port on the housing 2 of the display screen main body 1, installing a door panel 7 in the inspection port, providing a heat dissipation groove 5 on the door panel 7, and clamping the dustproof mesh plate 6 on the inner wall of the door panel 7, in actual use, the device is placed in a suitable position through the base 4 connected to the bottom bracket 3 of the housing 2. The display screen main body 1 generates heat during operation, and the heat dissipation groove 5 can provide good heat dissipation and ventilation capabilities for the display screen main body 1. At the same time, the dustproof mesh plate 6 can prevent external dust from entering the device and hindering the heat dissipation of electrical components on the basis of ensuring the heat dissipation capacity of the display screen;

[0032] Moreover, by installing the door panel 7 in the inspection gap on the outer shell 2, the heat dissipation groove 5 and the dustproof mesh plate 6 are both arranged on the door panel 7. On the one hand, the equipment can be inspected and maintained by opening the door panel 7; on the other hand, the dustproof mesh plate 6 is clamped on the U-shaped strip 8 with the clamping groove 9 on the inner wall of the door panel 7. Therefore, the dustproof mesh plate 6 can be quickly and conveniently installed and disassembled after opening the door panel 7, which is convenient for cleaning the dustproof plate during use, thereby improving the convenience of equipment use.

[0033] In general, the device has a simple structure and is easy to use. Through the cooperation of the heat dissipation groove 5 and the dustproof mesh plate 6, not only can the display screen have good heat dissipation capabilities, but also have good sealing and dustproof capabilities, preventing external dust from easily entering the interior of the display screen. At the same time, by opening the door panel 7, the dustproof mesh plate 6 can be quickly and conveniently installed, used, and disassembled for cleaning.

[0034] Also, see Figure 4-5 :

[0035] A rubber ring 10 is arranged around the frame of the dustproof mesh plate 6. When the dustproof mesh plate 6 is inserted into the slot 9 of the U-shaped strip 8, the rubber ring 10 is attached to the inner wall of the door panel 7, and a pulling hole 11 for pulling out the dustproof mesh plate 6 is opened on the top of the rubber ring 10.

[0036] By setting a rubber ring 10 on the frame of the dustproof mesh plate 6, when the dustproof mesh plate 6 is inserted into the card slot 9, the rubber ring 10 fits against the inner wall of the door panel 7. Such a design can further improve the sealing of the equipment, avoid the existence of a gap between the dustproof mesh plate 6 and the door panel 7, and ensure the dustproof performance of the equipment.

[0037] Among them, see Figure 3 A shift block 15 is also provided on one side of the outer wall of the door panel 7, and an empty slot 16 is provided on one side of the shift block 15. When opening the door panel 7, after the fixing screw on the ear seat 12 is removed, it is difficult to open. At this time, the shift block 15 with the empty slot 16 can provide convenience for the user, and the door panel 7 can be easily opened by inserting a finger into the empty slot 16 of the shift block 15, which further improves the convenience of the device.
