본 고안은 차량의 적재함 고정장치에 관한 것으로 특히 덤프트럭 등 적재함이 부착된 차량의 공차주행시 로면의 유동에 따라 적재함이 상하유동 됨으로서 차체와 적재함이 부딛쳐 서로 훼손되는 것을 방지키 위하여 적재함과 서브후레임 사이에 스프링탄성력을 이용한 자동로킹장치에 관한 것이다.The present invention relates to a storage box fixing device of a vehicle, and in particular, a loading box and a subframe to prevent the body and the loading box from being damaged due to the flow of the loading box up and down according to the flow of the road surface when the vehicle travels with a loading box such as a dump truck. It relates to an automatic locking device using the spring elastic force in between.

종래의 적재함 고정장치는 적재함 하단에 장착된 고정바를 압축고무의 탄성을 이용하여 후크로 체결한 것이어서 탄성고무의 적절한 굴성체크, 선정 및 제조가 어려우며 소요체결력의 변경등에 따른 모델변경이 어려운 결점이 있다.Conventional loading box fixing device is a fastening bar mounted on the bottom of the loading box by using the elasticity of the compressed rubber hook, it is difficult to properly elastic check, selection and manufacturing of elastic rubber, it is difficult to change the model due to the change of required tightening force .

또한 일본 실개소 49-39111호는 유압실린더에 의해 작동되는 고정장치이나 이는 유압실린더의 소요로 인한 경비문제로 실용화되지 못하고 있고 일본 실개소 9-67309호는 롤러 스라이딩 기구를 이용한 것이나 롤러의 마멸이 심할 경우 오작동되는 경우가 많다.In addition, Japanese Patent Application No. 49-39111 is a fixed device operated by a hydraulic cylinder, but this cannot be put to practical use due to the cost of hydraulic cylinders. Japanese Patent Application No. 9-67309 uses a roller sliding mechanism or roller wear. This is often a malfunction.

본 고안은 적재함 고정장치에 있어서 탄성고무 및 유압실린더 대신 자체 회전식 후크기구로 대치한 것으로 그 요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is replaced by the self-rotating hook mechanism in place of the elastic rubber and hydraulic cylinder in the storage box fixing device described in detail by the accompanying drawings as follows.

적재함(1)에 고정봉(2)이 설치된 고정바(3)가 부착되고 서브후레임(4)에 베이스힌지(5) (5')가 부착되어 앞쪽베이스힌지(5)에는 후크(6)가 축설되고 뒤쪽베이스힌지(5')에는 중간에서 스라이딩 되게 결합된 로드(7)가 축설되며, 지지판(9)(9')에 스프링시트(10)(10')를 설치하여 그 사이에 임의로 선정된 강재 스프링(11)을 탄입 설치한 구조에 있어서, 후크(6)의 중앙부는 앞쪽베이스힌지(5)의 핀측에 설치하고 후반부는 지지판(9)의 돌출브래킷에 핀(8)로 설치하여 적재함(1)의 강제 상승시 후크(6)가 자체적으로 회전되어 고정봉(2)를 해체시키는 구조이다.A fixing bar (3) having a fixed rod (2) is attached to the storage box (1), and a base hinge (5) (5 ') is attached to the subframe (4) so that the hook (6) is attached to the front base hinge (5). The rear base hinge 5 'is constructed with a rod 7 coupled to be slid in the middle, and spring seats 10, 10' are installed on the support plates 9, 9 ', and arbitrarily disposed therebetween. In the structure in which the selected steel spring 11 is inserted and mounted, the center portion of the hook 6 is installed on the pin side of the front base hinge 5, and the rear half portion is installed on the protruding bracket of the support plate 9 by the pin 8. The hook 6 is rotated by itself when the loading box 1 is forcedly lifted to dismantle the fixing rod 2.

이와 같이 된 본 고안은 덤프트럭 및 적재함, 탈, 착 차량의 공차 주행시 적재함의 상하 흔들림을 방지하는데, 강재 스프링의 탄성력을 이용하여 적재함의 무게 및 고정장치의 장착위치에 따른 소요체결력에 따라 적정 스프링의 선정이 가능하여 탄성계수의 차이로 인한 고정장치의 기능 저하 등의 페단이 제거되고 유압실린더의 필요와 이의 연결배관 등이 없어 경제적이고 간단하게 적재함의 상, 하 흔들림을 방지할 수 있는 것인데 특히 후크가 자체 회전으로 로킹상태를 유지 및 해제하는 구조이여서 종래와 같은 롤러 스라이딩식의 마멸이 감소됨으로 사용수명이 길고 오동작이 없는 등의 효과가 있는 것이다.The present invention thus prevents up and down shaking of the loading box during tolerance driving of dump trucks, loading boxes, and demountable vehicles, and appropriate springs according to the required tightening force according to the weight of the loading box and the mounting position of the fixing device by using the elastic force of the steel spring. It is possible to select the pedestal so that the pedestals such as deterioration of the fixing device due to the difference of elastic modulus are eliminated and there is no need of the hydraulic cylinder and the connecting pipes thereof. Since the hook is a structure that maintains and releases the locked state by its own rotation, the wear of the roller-sliding type as in the prior art is reduced, so that the service life is long and there is no malfunction.
