Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal screen assembly, in particular to a screen installation frame of a liquid crystal display. Background Art

[0002] Liquid crystal display, or LCD for short, is a substance between solid and liquid, an organic compound with regular molecular arrangement, which becomes a transparent liquid state when heated and a turbid solid state with crystal particles when cooled; liquid crystal screens, including LCD and LED displays, use electric current to stimulate liquid crystal molecules to produce dots, lines, and surfaces that form a picture with the back light tube. Compared with traditional cathode ray tube (CRT) displays, it is larger in size, has a softer picture, does not flicker, and reduces eye fatigue.

[0003] After packaging, the existing LCD screen is directly buckled with the matching screen mounting frame, and the buckling method is mostly a buckle structure matched with screws. This requires a large amount of manpower to operate during installation and disassembly, and when the LCD screen is disassembled and installed many times, the force is often difficult to control, resulting in wear or damage to the related buckle structure in the screen mounting frame, reducing the subsequent installation effect of the LCD screen, and the existing LCD screen is mostly rigidly connected to the screen mounting frame when installed, which is not conducive to the protection effect during transportation or daily use, because during transportation or daily use, the screen will inevitably be accidentally touched and cause shaking, which increases the probability of being damaged and easily shortens the service life of the screen.

At the same time, the disassembly piece 5 can also form a shock-absorbing and buffering effect for the screen edge strip 2 between the lower side of the screen edge strip 2, killing two birds with one stone, achieving the dual effects of installation and protection, and having a significant practical use effect.

[0028] The bottom support plate 4 is open at the top and bottom, and both ends of the bottom support plate 4 are integrally formed with retaining edges 24 for abutting against the lower edges of the mounting frame 3 , so that the lower front surface of the screen edge strip 2 can be abutted by the bottom support plate 4 .

[0029] Symmetrical screw holes for locking bolts 29 to penetrate and thread through are provided on both sides of the installation frame 3, and screw grooves for locking bolts 29 to be screwed into are provided at corresponding positions on the sides of the screen edge strip 2, so that the screen edge strip 2 together with the LCD screen 1 can be stably installed in the installation frame 3.

[0030] The connecting piece includes a threaded portion 30 for threaded connection with a threaded through hole 14 opened on the lower surface of the bottom support plate 4, a vertical smooth shaft portion 15 integrally formed at the end of the threaded portion 30, and a conical surface portion 10 integrally formed at the end of the smooth shaft portion 15, and a circle of annular grooves 13 for triggering the positioning piece to slide and snap in are opened on the middle circumference of the smooth shaft portion 15.
