DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A portable electronic information display screen comprises a base 1, a display screen body 3 is arranged on the top of the base 1 through a mounting frame 2, a battery 4 electrically connected to the display screen body 3 is placed inside the bottom of the mounting frame 2, and a control panel 5 is arranged on the side thereof, and the control panel 5 is electrically connected to the display screen body 3 and the battery 4;

[0022] Among them, an adjustment component 6 is provided in the mounting frame 2, and the adjustment component 6 is used to adjust the height of the display screen body 3. The adjustment component 6 also includes a buffer component 7 for protecting the display screen body 3. The top telescopic component 8 of the mounting frame 2 is provided with a handle 9. The battery 4 is electrically connected to an external power supply to provide power for the display screen body 3, the control panel 5 and the electric push rod 62 by storing electricity.

[0023] Specifically, a heat dissipation slot 21 is formed on the side of the bottom of the mounting frame 2 , and a universal wheel 22 is rotatably connected to the bottom thereof and a foot 23 is fixedly installed thereon.

[0024] In detail, the heat dissipation groove 21 is provided to prevent the battery 4 and the display screen body 3 from generating heat, and the universal wheel 22 is used in conjunction with the handle 9 to facilitate the movement of the electronic information display screen, and then the foot 23 is pressed against the ground to fix the electronic information display screen, preventing the universal wheel 22 from rotating at will.

[0025] Furthermore, the adjustment component 6 includes guide grooves 61 provided on both sides of the mounting frame 2, the guide grooves 61 pass through the side surfaces of the mounting frame 2, and an electric push rod 62 electrically connected to the battery 4 and the control panel 5 is fixedly installed on the inner bottom surface thereof, and the buffer member 7 is provided on the top of the axial end of the electric push rod 62 and is slidably connected to a first fixed plate 63.

[0026] The specific operation is to control the lifting and lowering of the output shafts of the pair of electric push rods 62 through the control panel 5, and cooperate with the first fixing plate 63 and the second fixing plate 64 to drive the display screen body 3 to adjust the height.

[0027] In more detail, the buffer member 7 includes a buffer cylinder 71 fixedly mounted on the top of the axial end of the electric push rod 62, a vent hole 72 is opened at the bottom of the buffer cylinder 71, and a piston rod 73 is slidably connected inside the buffer cylinder 71, a second fixed plate 64 is fixedly mounted on the top of the piston rod 73, a spring 74 is sleeved on the outer periphery of the buffer cylinder 71, and both ends of the spring 74 are respectively fixedly connected to the bottom of the buffer cylinder 71 and the bottom surface of the second fixed plate 64, the first fixed plate 63 and the second fixed plate 64 are slidably connected in the guide groove 61, and their sides are fixedly connected to the sides of the display screen body 3.

[0028] It should be added that the first fixing plate 63 is fixedly connected to the buffer cylinder 71, so that when the electric push rod 62 drives the buffer cylinder 71 to move, the first fixing plate 63 can be driven to follow the movement, and the second fixing plate 64 can cooperate with the first fixing plate 63 to keep the display screen body 3 moving smoothly;

[0029] Then, when the display screen body 3 shakes or collides, the display screen body 3 drives the second fixing plate 64 and the piston rod 73 to move downward or upward, and the piston rod 73 moves slowly due to the vent hole 72 to achieve the effect of buffering and shock absorption. Then, under the action of the spring 74, the display screen body 3 returns to its original position;

[0030] In addition, the piston rod 73 is located in the buffer cylinder 71 and is fixedly connected to a piston head. The piston head is used to maintain the sealing of the buffer cylinder 71, ensuring that the piston rod 73 can compress air for buffering and shock reduction when moving.

[0031] In general, the telescopic member 8 includes a mounting groove 81 provided in the top of the mounting frame 2, the handle 9 is slidably connected inside the mounting groove 81, the bottom of the handle 9 is fixedly connected to a limiting plate 83, the mounting groove 81 can clamp the limiting plate 83, and a pair of tension springs 82 are fixedly connected to its inner bottom surface, and the other end of the tension spring 82 is fixedly connected to the bottom of the limiting plate 83.

[0032] Through the action of the tension spring 82 , when the electronic information display screen is not moved, the handle 9 is arranged in the installation groove 81 , and then the handle 9 is pulled to facilitate the movement of the electronic information display screen. Because of the action of the limiting plate 83 , the handle 9 will not be separated from the installation groove 81 .

[0033] Finally, there are card slots 84 on both sides of the installation slot 81, and elastic protrusions 85 on both sides of the handle 9. The elastic protrusions 85 can be snapped into the card slots 84. The advantage of having the card slots 84 and the elastic protrusions 85 is that when the handle 9 is pulled, the elastic protrusions 85 will be snapped into the card slots 84, so that when the handle 9 is released, the handle 9 will not return to the installation slot 81, thereby preventing the handle 9 from returning to the installation slot 81 and affecting use when changing the left or right hand or stopping for a while.

[0034] Working mode: When working, pull the handle 9 to make the elastic protrusion 85 snap into the slot 84, cooperate with the universal wheel 22 to move the electronic information display screen, then use the foot 23 to contact the ground to fix the electronic information display screen, and then control the output shaft of a pair of electric push rods 62 through the control panel 5 to drive the display screen body 3 to rise and fall;

[0035] When the display screen body 3 collides or shakes, the first fixing plate 63 is used to squeeze or drive the piston rod 73 to rise and fall. The piston rod 73 moves slowly due to the vent hole 72 to achieve the effect of buffering and shock absorption, and then returns to its original position under the action of the spring 74.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
