AI Technical Summary
If the operator does not hold the upper support tube during the height adjustment process of the existing screen bracket, the screen may drop sharply and be damaged.
A screen support with a buffer structure was designed, including an inner support tube and an outer support tube. The inner support tube uses friction and a gas buffer structure to control the descent speed through the cooperation of buffer columns and limiting holes, thus avoiding a sudden drop.
It effectively prevents the screen bracket from dropping sharply when adjusting the height, protecting the integrity of the screen, and reduces noise by using gas buffer to slow down the speed.

TECHNICAL FIELD
[0001] The utility model relates to the field of screen support, specifically to a screen support with buffer structure. BACKGROUND
[0002] As an indispensable device in the audio-visual field, the screen is a carrier for projecting images. Through special material and surface treatment, it can accurately reflect light and clearly and vividly present the content of films, presentations, etc. to the audience. From the early rough white cloth to the current professional screen with high gain, wide viewing angle and other characteristics, its development process has been constantly adapting to people's pursuit of high-quality visual experience, and it plays a key role in movie theaters, conference rooms, home theaters and other scenarios.
[0003] The screen support is an important component that supports the screen and ensures its stable display, to prevent shaking, tilting and other factors that affect the viewing effect during use. The screen support is generally composed of two support tubes. The upper support tube is inserted into the inner cavity of the lower support tube. The end of the lower support tube is fixedly installed with a locker. When the height of the screen support needs to be adjusted, the person holds the upper support tube and pries open the locking handle on one side of the locker, so that the locker releases the fixed restriction on the upper support tube, allowing the height, angle, etc. of the screen to be adjusted according to the actual environment and user needs, providing the best viewing angle for the audience.
[0004] In the process of adjusting the height of the existing screen support, the person needs to hold the upper support tube.

[0011] By adopting the technical scheme, since the end of the outer support pipe is sealed by the box cover, the second inner cavity in the inner support pipe is in a relatively closed space.
[0012] The utility model further sets up, the both sides of inner support pipe are provided with reinforcing plate, and the friction coefficient of reinforcing plate surface material is greater than the friction coefficient of inner support pipe outer wall material.
[0013] By adopting the technical scheme, the reinforcing plate can strengthen the overall strength of the inner support pipe, and the friction coefficient of the reinforcing plate surface material is relatively large, so that the extrusion of the first buffer column on the inner support pipe can be increased.

[0016] The utility model further sets up, the diameter of first gas permeation hole is greater than the diameter of second gas permeation hole, and the spacing between first gas permeation hole and second gas permeation hole is greater than the length of first buffer block.
[0017] By adopting the technical scheme, the gas in the second inner cavity enters the inner support pipe through the first gas hole first, and then enters the first inner cavity through the second gas hole, thereby avoiding the explosion phenomenon of the gas in the second inner cavity when passing through the gas hole with a smaller diameter.
