DETAILED DESCRIPTION

[0017] 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 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.

[0018] like Figure 1-Figure 6 As shown, a preferred embodiment of the utility model proposes a liftable HDMI interface display screen, which mainly includes components such as a display screen body 1, a bracket 2, two fixed bars 3 and four rotating top rods 4, wherein the bracket 2 is a cylindrical structure, the two fixed bars 3 are respectively fixedly installed on the rear side of the display screen body 1, and both ends of the bottom of the two fixed bars 3 are connected with slidable rotating top rods 4, and one end of the four rotating top rods 4 away from the fixed bars 3 is connected to the bracket 2. The four rotating top rods 4 rotate on the bracket 2 and the rotating top rods 4 slide on the fixed bars 3 to push the fixed bars 3 upward, so that the fixed bars 3 drive the display screen body 1 to adjust the height.

[0019] like Figure 1 As shown, four threaded holes are opened on the rear side of the display screen body 1, and mounting holes are opened at both ends of the two fixing bars 3. Threaded bolts are connected between the fixing bars 3 and the display screen body 1 through the threaded holes and the mounting holes, so that the fixing bars 3 can be effectively installed and removed.

[0020] refer to Figure 2 , a horizontal sliding groove 5 is provided at the bottom of the two fixed bars 3, and a sliding rod 6 is fixedly connected inside the horizontal sliding groove 5. Slide blocks 7 are slidably sleeved on both sides of the sliding rod 6. The ends of the four rotating top rods 4 away from the bracket 2 are respectively rotatably connected to the bottoms of the four slide blocks 7, so that the rotation of the rotating top rods 4 can effectively push the fixed bar 3 and the display screen body 1 to move upward; when the four rotating top rods 4 rotate on the bracket 2, the four rotating top rods 4 will drive the slide block 7 to slide on the slide bar 6, and finally make the two slide blocks 7 on the same slide bar 6 slide relative to each other, so that the rotation of the rotating top rod 4 pushes the fixed bar 3 and the display screen body 1 to move upward, so that the height of the display screen body 1 can be adjusted.

[0021] refer to Figure 3 A transmission cavity 8 is provided in the middle of the bracket 2, and two rotating pins 9 are rotatably connected to the upper and lower parts of the transmission cavity 8. One ends of the four rotating pins 9 extend to the surface of the bracket 2 and are respectively connected to the four rotating push rods 4. The surface of the rotating pin 9 located outside the bracket 2 is provided with a square section and a threaded end. The end of the rotating push rod 4 away from the slider 7 is provided with a square sleeve hole. The rotating push rod 4 is installed on the square section on the rotating pin 9 through the square sleeve hole, and the threaded end on the rotating pin 9 is connected with a nut to connect and fix the rotating push rod 4, so that the rotating push rod 4 can be effectively disassembled and separated from the rotating pin 9.

[0022] like Figure 3-Figure 5 As shown, a gear 10 is fixedly connected to the middle of the two rotating pins 9 at the upper and lower parts of the transmission chamber 8, and the two gears 10 at the same height are meshed and connected. One end of each rotating pin 9 at the upper and lower parts of the transmission chamber 8 is fixedly connected to a worm gear 11. A motor 12 is installed at the bottom of the transmission chamber 8. A worm 13 is fixedly connected to the output end of the motor 12. The worm 13 is meshed and connected with the two worm gears 11. The motor 12 is a high-torque forward and reverse motor of the brand Zhengke and the model is ZGB37RG, so that it can be effectively adjusted. The surface of the bracket 2 is installed with Control switch, the control switch is connected to the motor 12 through an electric wire, and the control switch is connected to an external power supply through a power cord. The worm 13 is rotated by starting the motor 12, and the rotation of the worm 13 will drive the two worm wheels 11 to rotate. The rotation of the two worm wheels 11 will cause two rotating pins 9 at the same height to rotate relative to each other through two pairs of meshing gears 10. The relative rotating pins 9 will drive two rotating top rods 4 at the same height to rotate relative to each other, and starting the motor 12 in reverse can make the two rotating top rods 4 rotate back to back and adjust.

[0023] refer to Figure 6 Mounting grooves 14 are equidistantly provided in a ring at the bottom of the bracket 2, two of which are rotatably connected to front support blocks 15, and another of which is rotatably connected to a rear support block 16. The two front support blocks 15 and the rear support blocks 16 are equidistantly arranged at 60°, so that the support can be effectively provided to maintain the stability of the bracket 2, and the rotation adjustment can be effectively performed.

[0024] When the display screen body 1 and the bracket 2 need to be disassembled, first rotate the disassembly threaded bolt to separate and disassemble the two fixing bars 3 from the display screen body 1, then rotate the nut on the threaded end of the rotating pin 9 to remove the rotating top rod 4 from the square section of the rotating pin 9, so that the four rotating top rods 4 are separated from the bracket 2, and then rotate the two front support blocks 15 and the rear support block 16 to make the front support block 15 and the rear support block 16 parallel to the bracket 2, so that the display screen body 1, the bracket 2, the two fixing bars 3 and the four rotating top rods 4 can be conveniently packed and carried.

[0025] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
