Description

Technical area

The invention relates to a tripod, in particular a mounting stand with sealing positioning and a telescopic positioning rod with sealing positioning, wherein the sealing positioning of the mounting stand and the telescopic positioning is outside diameter adjustable and thus without the support of other components alone attachable and positionable.

State of the art

Conventional loudspeakers are usually mounted on a tripod for speaker boxes and positioned at an appropriate height. In the conventional stands for loudspeaker boxes, a mounting base is arranged at the upper end of the stand, protruding from the upper end of a mounting rod, which is inserted into a mounting hole at the bottom of the speaker. However, the dimension of the mounting hole at the bottom of the speaker is different; if the mounting hole is smaller than the mounting rod, the mounting rod can not be held; if the attachment hole is larger than the attachment rod, an excessively large gap will be formed between the attachment rod and the attachment hole when the attachment rod is inserted through the attachment hole, whereby the speaker can not be fixed reliably.

Furthermore, a conventional microphone is attached to a telescopic stand having a telescopic tube assembly in which an inner tube is inserted into an outer tube. In such a telescopic tube assembly, usually a positioning knob is passed through the outer tube and presses the inner tube to position the telescopic tube assembly. In some circumstances, the user of the microphone is constantly being replaced, with each user having to loosen and tighten the positioning knob to adjust the height of the telescopic stand, which can result in a delay in the operation of an important event or meeting.
