The present invention relates to a separation prevention type safety handcart, comprising: a base moving portion; and a plurality of close supporting units. The base moving portion is provide with a base plate which is installed with a plurality of casters in a horizontally located plate shaped lower surface portion such that the base plate is rolled and moved. In the base plate, a plurality of unit mounting portions at a certain gap in front, back, left, and right directions are formed, wherein each of the unit mounting portions comprises: a unit installation hole; a housing securing end formed at the front and back of the unit installation hole; and a cover securing end formed at left and right sides of the unit installation hole. The close supporting units are provided with a unit housing opened at the top, wherein the unit housing is interposed through the unit installation hole and is opened in a prefabricated upper portion while a flange portion of an upper end portion at front, back, and both sides is secured on a housing securing end. In the opened upper portion of the unit housing, a fastening cover is coupled and both left and right sides of the fastening cover are secured on the cover securing end. In the unit housing, one or a plurality of support shafts are installed to be vertically elevated while being elastically supported upwardly by an elastic spring. The upper portion of the support shaft penetrates through the fastening cover and protrudes to the outer side of the upper potion by a certain length such that the support shaft is prefabricated in each unit mounting portion while the support shaft is elastically and closely supporting the lower surface portion of a transportation object so as to prevent separation of the transportation object from the bottom portion during transporting the transportation object.

    본 발명은 수평으로 위치된 판형상으로 하면부에 다수개의 캐스터가 설치되어 구름이동되는 베이스판이 구비되고 베이스판에는 전후좌우 일정간격으로 복수개의 유닛장착부가 형성되어 있되 각 유닛장착부는 유닛설치홀과 유닛설치홀의 전후방에 형성된 하우징안착단과 유닛설치홀의 좌우측에 형성된 커버안착단으로 이루어져 있는 베이스이동부와, 상기 유닛설치홀에 관통 개재되면서 전후양측 상단부의 플랜지부가 하우징안착단 위에 안착된 상태로 조립설치되는 상부가 개구된 유닛하우징이 구비되고 유닛하우징의 개구된 상부에는 체결커버가 결합되면서 체결커버의 좌우양측이 커버안착단 위에 안착되어 조립설치되며 유닛하우징의 내부에는 하나 또는 복수개의 지지축이 수직으로 승강되게 설치되면서 탄성스프링에 의해 상방으로 탄성지지되도록 되어 있되 상기 지지축의 상부는 체결커버를 관통하여 상부 외측으로 일정길이 돌출되도록 되어 있어 각 유닛장착부에 조립설치되면서 운반물의 하면부를 지지축이 탄성적으로 밀착지지하여 운반도중 운반물의 하부로부터의 이탈을 방지하는 복수개의 밀착지지유닛으로 구성된 것을 특징으로 하는 이탈방지형 안전이동대차에 관한 것이다.
