The present invention relates to an electric cylinder with cushioning structure, which comprises a lead screw, an external sleeve, a telescopic tube, and a cushioning structure. The external sleeve is fitted at the exterior of the lead screw. The telescopic tube is penetrated through the external sleeve and provided with a screw nut screwed with the lead screw for transmission. The cushioning structure comprises a positioning member and a cushioning unit. The positioning member is fixed with the lead screw. The cushioning unit is fitted onto the lead screw and mounted between the screw nut and the positioning member. Thus, the present invention may absorb the impact force generated by rapid descending of the telescopic tube.本發明係關於一種具有緩衝結構的電動缸,其包括一導螺桿、一外管、一伸縮管及一緩衝結構,外管套設在導螺桿外部;伸縮管穿接外管,伸縮管具有與導螺桿螺接傳動的一螺帽;緩衝結構包括一定位件及一緩衝單元,定位件固定在該導螺桿;緩衝單元套設在導螺桿且界於螺帽和定位件之間。藉此,可吸收伸縮管在快速下降過程中所產生的衝擊力。30...傳動機構31...蝸輪32...導螺桿33...軸承351...螺帽50...緩衝結構51...定位件512...插銷52...緩衝單元53...後接環54...前接環
