Problems solved by technology
[0004] And the exhibition truss is generally a square frame structure welded by steel materials. However, when the exhibition truss is transported to the site for splicing, each section of the exhibition truss needs to be fixed and connected with four screws in the square hole. Therefore, the exhibition truss Assembly wastes a lot of labor and time

The invention relates to a device for quickly tightening screws of an exhibition truss. The device for quickly tightening the screws of the exhibition truss is characterized in that a fixing frame, a supporting box, a motor, a reduction gearbox, a supporting shell, a grip, four screw sleeves, a transmission rod, a driving friction wheel and four driven friction wheels serve as a main body; the supporting box is in an annular shape and is internally hollowed out, and a transmission ring which is clamped to the edge of the supporting box and can rotate is arranged in the supporting box. A bracket is arranged on the supporting box; the upper surface of the transmission ring is provided with four first fixing pins which are evenly distributed in the annular shape and fixedly connected with the transmission ring, four second fixing pins which are evenly distributed in the annular shape and fixedly connected with the supporting box are arranged in the supporting box, and the first fixing pins and the second fixing pins are sleeved with one end of the transmission rod and one end of the supporting shell respectively. According to the device for quickly tightening the screws of the exhibition truss, the driving friction wheel always abuts against the four driven friction wheels, so that the four screw sleeves can rotate all the time after the distance is changed, the design is ingenious, the four screw sleeves are easy to lock after the distance is adjusted through cooperation of a worm and worm teeth, and operation is convenient and fast.
Description
technical field [0001] The invention relates to the technical field of auxiliary devices for truss splicing, in particular to a device for quickly tightening screws of an exhibition truss. Background technique [0002] Generally, trusses are often used in celebration activities. The truss members are mainly subjected to axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials, reduce self-weight and increase stiffness compared with solid web beams. . [0003] The exhibition truss is a kind of exhibition frame; the use and characteristics of the exhibition truss: it is widely used in the construction of exhibition venues, display platforms, stage backgrounds and large-span picture display carriers. Carry out a large-scale outdoor event display. [0004] And the exhibition truss is generally a square frame structure welded by steel material, but when the exhibition truss is transported to the site fo...
