[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of 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.

[0021] like Figure 1 , Figure 2 As shown, a preferred embodiment of the utility model proposes an HDMI interface display screen fixing device, which mainly includes a support base 1, a support frame 2, a support beam 3, a buffer protection mechanism 4 and other components, wherein the support frame 2 is fixed at the top of the support base 1, the display screen is installed at the top of the front side of the support frame 2, the support beam 3 is fixed at the top of the back side of the support frame 2, and two buffer protection mechanisms 4 are provided, which are respectively arranged at the two ends of the support beam 3 to play a buffer protection role.

[0022] like Figure 3As shown, the buffer protection mechanism 4 is composed of a combined buffer arm 5 and a gravity-adaptive buffer seat 6. One end of the combined buffer arm 5 is inserted into the supporting beam 3 and is rotatably connected to the supporting beam 3 through a rotating shaft 7. The gravity-adaptive buffer seat 6 is fixedly connected to the end of the combined buffer arm 5 away from the supporting beam 3. When in use, the display screen is supported by the support frame 2, and buffer protection is achieved through the buffer protection mechanism 4. When the support frame 2 is collided and tilted, the display screen is safely protected by the cooperation of the combined buffer arm 5 and the gravity-adaptive buffer seat 6. The original position of the buffer protection mechanism 4 is located on the back of the display screen. If the support frame 2 tilts toward the back, the gravity-adaptive buffer seat 6 is still affected by gravity to form buffer protection on the back. If the support frame 2 tilts toward the front, the gravity-adaptive buffer seat 6 is affected by its own gravity and rotates around the rotating shaft 7 and moves to the front of the display screen to achieve buffer protection.

[0023] refer to Figure 2-Figure 6 The above-mentioned combined buffer arm 5 is composed of a sleeve 8, a telescopic arm 9, a buffer spring 10, an N-pole magnet 11, a buffer spring 2 12 and an N-pole magnet 2 13, wherein the telescopic arm 9 is slidably inserted into the end of the sleeve 8 away from the rotating shaft 7, one end of the buffer spring 10 is fixedly connected to the telescopic arm 9, the N-pole magnet 11 is slidably connected to the inside of the sleeve 8 and is fixedly connected to the other end of the buffer spring 10, one end of the buffer spring 2 12 is fixedly connected to the sleeve 8, the N-pole magnet 2 13 is slidably connected to the inside of the sleeve 8 and is fixedly connected to the other end of the buffer spring 2 12. During buffer protection, the telescopic arm 9 is subjected to thrust and moves into the sleeve 8, and buffer protection is achieved by the buffer spring 10 and the buffer spring 2 12. The N-pole magnet 11 and the N-pole magnet 2 13 have the same magnetic poles, generating a repulsive force, thereby achieving secondary buffering.

[0024] refer to Figure 5 The gravity-adaptive buffer seat 6 is composed of an inclined support plate 14, a counterweight 15 and a rubber seat 16. The inclined support plate 14 is fixedly connected to the end of the telescopic arm 9 away from the sleeve 8, the counterweight 15 is fixedly connected to one side of the inclined support plate 14, and the rubber seat 16 is fixedly connected to the end of the inclined support plate 14 away from the telescopic arm 9. The inclined support plate 14 is a triangular structure, the counterweight 15 is staggered with the telescopic arm 9, and a plurality of through holes 17 are provided on the rubber seat 16. Through the biased setting of the inclined support plate 14 and the counterweight 15, when the display screen tilts toward the front, the combined buffer arm 5 can be driven to rotate quickly, thereby realizing rapid support. The rubber seat 16 and the through hole 17 can realize three-level buffering, effectively reducing the impact force and improving the safety of the display screen.

[0025] like Figure 3As shown, a limit seat 18 matching the sleeve 8 is fixedly provided at both ends of one side of the supporting beam 3, and a limit seat 2 19 matching the sleeve 8 is fixedly provided at both ends of the other side of the supporting beam 3. The limit seat 18 and the limit seat 2 19 can be used to limit the sleeve 8 to prevent the sleeve 8 from rotating in the opposite direction and colliding with the display screen.

[0026] refer to Figure 6 An S-pole weak magnetic magnet 20 is fixedly arranged on one side of the limit seat 18 close to the sleeve 8, and an N-pole weak magnetic magnet 21 matching the S-pole weak magnetic magnet 20 is fixedly arranged at one end of the side of the sleeve 8. The attraction between the S-pole weak magnetic magnet 20 and the N-pole weak magnetic magnet 21 can realize the magnetic attraction of the sleeve 8, and prevent the sleeve 8 from rotating by itself during normal use.

[0027] like Figure 1 and Figure 2 As shown, the support frame 2 is composed of a limiting support sleeve 22, a plurality of reinforced inclined beams 23, a lifting support arm 24, a locking knob 25, a display screen mounting plate 26 and other components, wherein the limiting support sleeve 22 is fixedly connected to the top of the support base 1, the reinforcing inclined beam 23 is fixedly connected between the limiting support sleeve 22 and the support base 1, the lifting support arm 24 is slidably connected to the inside of the limiting support sleeve 22, the locking knob 25 is connected to the top of the back side of the limiting support sleeve 22 and matches the lifting support arm 24, the display screen mounting plate 26 is fixedly connected to the top of the front side of the lifting support arm 24, and the display screen mounting plate 26 can realize fixed installation of the display screen. When the height of the display screen needs to be adjusted, the locking knob 25 is released to allow the lifting support arm 24 to slide in the limiting support sleeve 22, and then it can be locked by the locking knob 25.
