Description
Technical field
The utility model relates to a kind of sound rack.
Background technology
The sound rack of prior art comprises leg, hollow mobile jib, expansion link and sound equipment support; Described leg is located at the bottom of hollow mobile jib, and described expansion link is set in the hollow mobile jib, and the upper end of expansion link hangs with sound equipment; Described expansion link is provided with round, and the tube wall of described hollow mobile jib is provided with screw; Described expansion link and hollow mobile jib are bolted to connection; The lift adjustment of sound rack is earlier bolt to be back-outed from screw, again the height of expansion link is regulated, again bolt will be tightened after will regulating height, the problem that prior art exists is: the upper end of expansion link hangs with sound equipment, because sound equipment is heavier, when regulating height, expansion link may occur and fall suddenly, cause peril.
The utility model content
The technical problems to be solved in the utility model is that a kind of sound rack that prevents that sound rack from falling suddenly when regulating height is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of sound rack, and it comprises leg, hollow mobile jib and expansion link; Described leg is located at the bottom of hollow mobile jib, and described expansion link is set in the hollow mobile jib; Expansion link is provided with round, and the tube wall of described hollow mobile jib is provided with through hole; Described sound rack also comprises first seal member and second seal member; Described first seal member is fixedlyed connected with the bottom of expansion link, and the area of first seal member is identical with the hollow area of hollow mobile jib; Described second seal member is fixedlyed connected with hollow mobile jib lower end, and the area of second seal member is not less than the hollow area of hollow mobile jib.
After adopting above structure, the utlity model has following advantage: be provided with apron in hollow mobile jib lower end, be provided with the radius apron identical again with the radius of hollow mobile jib in the lower end of expansion link, make expansion link in the process of lifting, the air pressure inside of hollow stem can form resistance and prevent falling suddenly of expansion link, thereby has avoided the generation of peril.
