4results about How to "Increase the vibration area" patented technology

The invention discloses a telescopic, foldable and multi-point expandable vibrating rod which comprises a straight end, a folding end, a vibrating end and a power device, wherein the upper end of the folding end is hinged to the straight end; the vibrating end is detachably connected with the straight end or the folding end; the power device is used for providing power for the straight end; the straight end comprises a straight end frame, a straight end rotating screw rod, a connecting female head, an input gear, a transmission gear and a straight end output hole; the folding ends are hinged to the two ends of the straight end in a turnover mode respectively, and a channel allowing the output end of the power device to pass through is formed in the middle of each folding end. The folding end can be overturned to the two ends of the straight end and forms an expansion structure with the straight end, and the two ends of the expansion structure extend; the vibrating end is detachably connected with the straight end output hole and the folding end output hole; the concrete vibrating device can achieve large-range concrete vibrating, eliminate bubbles in concrete, enable the concrete to be compactly combined and eliminate the phenomena of voids, pitted surfaces and the like of the concrete, so that the strength of the concrete is improved, and the quality of concrete members is guaranteed.
