Compared with the prior art, the beneficial effect of the utility model is: the concrete vibrator for civil engineering adopts the design of shock-absorbing support, sound-absorbing board, second handle, connecting rod, timer, ring groove and rotating shaft, which can reduce vibration The support can absorb the vibration generated by the vibration motor and prevent the vibration generated by the vibration motor from being transmitted to the worker's palm through the handle, which is beneficial for the workers to continue to vibrate the concrete. The sound-absorbing board with a porous structure can absorb the noise generated by the vibration motor during operation It is beneficial to the physical and mental health of workers. The second handle with porous structure and rigid foam material can absorb the noise generated when the rubber tube vibrates, and can prevent the vibration of the rubber tube from being transmitted to the palm of the worker. When the concrete is vibrated for more than one minute, The homogeneity of concrete is easily destroyed, resulting in concrete stratification, bleeding and segregation of concrete, affecting the quality of concrete, and reducing the strength of concrete. Therefore, the design of the timer can remind workers at all times to prevent workers from forgetting to turn off the vibration. The tamping rod causes the concrete to be over-vibrated, the second handle, the connecting rod, the ring groove and the rotating shaft can form a "back" shape, which is convenient for the winding of the rubber tube, and the ring groove and the rotating shaft can be used by workers when using the vibrating rod. Indirectly controls the position of the rubber tube.
