Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Such asFigures 1 to 6 As shown in the figure, a combined LCD liquid crystal screen includes a housing 1. Four LCD liquid crystal screen bodies 2 are fixedly arranged inside the housing 1. Two symmetrically arranged sliding rods 5 are installed inside the housing 1. A cross plate 6 is slidably connected to the outer surfaces of the two sliding rods 5. The sliding rods 5 can be used to guide and limit the up and down movement of the cross plate 6, so that the cross plate 6 can fix the LCD liquid crystal screen. Two symmetrically arranged second connecting springs 7 are installed between the cross plate 6 and the housing 1. A telescopic pressing plate 3 for fixing the LCD liquid crystal screen body 2 is slidably connected to the top end inside the housing 1;

[0028] A first connecting spring 4 is fixedly connected between the telescopic pressing plate 3 and the housing 1 and is distributed in an array. Through the installation and use of the telescopic pressing plate 3 and the cross plate 6, the elastic telescopic pressing plate 3 and the cross plate 6 with elasticity can elastically fix the LCD liquid crystal screen, avoiding hard clamping damage to the LCD liquid crystal screen and increasing the safety during the combination of the LCD liquid crystal screens. Limiting baffles 8 for positioning the LCD liquid crystal screen body 2 are rotatably connected to the inner sides of the telescopic pressing plate 3 and the cross plate 6. Four symmetrically arranged movable rotating plates 9 are rotatably connected to the inner side of the housing 1. Protrusions 10 for positioning the LCD liquid crystal screen body 2 are connected to the front sides of the four movable rotating plates 9. Through the installation and use of the limiting baffles 8 and the protrusions 10, the two can support and limit the rear of the LCD liquid crystal screen, making the combination of the LCD liquid crystal screen more stable. A rear cover 15 is fixedly arranged at the rear side of the housing 1.

[0029] The third connecting springs 16 are connected to the front side of the rear cover 15 in an array. A circular plate 17 is installed on the front sides of the third connecting springs 16. Pressing rods 18 are fixedly connected to the front side of the circular plate 17 and are distributed in an array. Through the arrangement of the pressing rods 18, the pressing rods 18 can elastically support the four LCD liquid crystal screens by the elastic force of the third connecting springs 16, increasing the stability during the combination. The pressing rods 18 are used to support the LCD liquid crystal screen body 2.

[0030] Two second L-shaped clamping plates 12 for fixing the limiting baffle 8 are slidably clamped to the lower side of the telescopic pressing plate 3. The upper side of the telescopic pressing plate 3 penetrates through the telescopic pressing plate 3 and extends to the upper side of the telescopic pressing plate 3. Two first L-shaped clamping plates 11 for fixing the limiting baffle 8 are slidably clamped to the upper side of the cross plate 6. The lower side of the first L-shaped clamping plate 11 penetrates through the cross plate 6 and extends to the lower side of the cross plate 6.

[0031] A damper 19 is installed in an array between the cross plate 6 and the housing 1. Through the setting of the damper 19, the resistance provided by the damper 19 is used to consume the vibration force, so as to achieve the effect of buffer protection and better protect the combined LCD liquid crystal screen. Heat dissipation holes 20 are arranged in an array inside the circular plate 17, and heat sinks 21 are connected in an array inside the rear cover 15. Through the setting of the heat sinks 21, the heat sinks 21 will fit against the rear of the LCD liquid crystal screen, and the heat will be transferred to the heat sinks 21, and then the heat sinks 21 with a larger surface area will dissipate the heat to reduce the temperature of the LCD liquid crystal screen.

[0032] Four first filter plates 22 are installed inside the rear cover 15. Lower inclined slots 23 are arranged in an array at both ends of the housing 1. Through the setting of the lower inclined slots 23, the lower inclined slots 23 have downward openings for heat dissipation, and at the same time, it can prevent water in the outside world from entering the inside of the housing 1, with good safety. A second filter plate 24 is fixedly arranged inside the lower inclined slots 23.

[0033] Four fixing columns 13 are respectively fixedly installed inside the housing 1. Plug plates 14 are clamped at the rear sides of the four fixing columns 13, and one side of the plug plate 14 is connected to the inside of the rear cover 15.

[0034] The working principle of a combined LCD liquid crystal screen provided by the present utility model is as follows:

[0035] By placing the front surface of the housing 1 on the desktop and then respectively clamping the four LCD liquid crystal screen bodies 2 into the inside of the housing 1, at this time, the LCD liquid crystal screen bodies 2 can compress the telescopic pressure plate 3 installed with the first connecting spring 4 and the cross plate 6 installed with the second connecting spring 7. In this way, the elastic telescopic pressure plate 3 and the cross plate 6 can elastically clamp the four LCD liquid crystal screen bodies 2 for splicing and combination. Subsequently, the two limiting baffles 8 are rotated in sequence, and at the same time, the second L-shaped clamping plate 12 at the telescopic pressure plate 3 and the first L-shaped clamping plate 11 at the cross plate 6 are used to fix the limiting baffles 8, so that the two limiting baffles 8 support and fix the LCD liquid crystal screen bodies 2. Then, the four movable rotating plates 9 are rotated in sequence, so that the convex blocks 10 at the movable rotating plates 9 can simultaneously position the four LCD liquid crystal screen bodies 2 to ensure the stability of the combined LCD liquid crystal screen. In this way, the splicing of the LCD liquid crystal screen is facilitated by the clamping and fixing method, and the combination is simple and convenient, so that the liquid crystal screen can be quickly removed for maintenance, which is beneficial to improving the maintenance efficiency of the combined LCD liquid crystal screen;

[0036] By clamping the four insertion plates 14 at the rear cover 15 into the four fixing posts 13, the housing 1 and the rear cover 15 can be assembled. With the installation of the rear cover 15, the circular plate 17 installed with the third connecting spring 16 can be driven close to the LCD liquid crystal screen body 2. In this way, the pressing rods 18 at the circular plate 17 can fix the four LCD liquid crystal screen bodies 2 at the same time, making the LCD liquid crystal screen body 2 not easy to loosen, increasing the stability of the combined LCD liquid crystal screen. Then, the heat dissipation holes 20, the heat sinks 21 and the lower inclined grooves 23 can play a role in heat dissipation, assisting in the rapid dissipation of heat. At the same time, the first filter plate 22 and the second filter plate 24 can also perform dust-proof treatment on the combined LCD liquid crystal screen, preventing too much dust from entering the inside of the combined LCD liquid crystal screen and affecting its normal use. Then, by using the elasticity of the second connecting spring 7 and the damper 19, the cross plate 6 can have the ability of elastic buffering, which is used to buffer and protect the LCD liquid crystal screen, and extend the service life of the combined LCD liquid crystal screen.
