본 발명은 무거운 물건을 들어올리는 잭(Jack)에 관한 것으로서, 특히 자동차를 정비하고자 할 때 자동차가 경사진 위치에 놓여 있더라도 회전체를 갖는 잭을 이용하여 자동차를 경사진 상태로 들어올려 주도록 하는 다용도 잭에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jack for lifting a heavy object. Particularly, the present invention relates to a jack for lifting a car in an inclined state by using a jack having a rotating body even when the car is in an inclined position when a car is to be maintained. It's about Jack.
일반적으로 자동차내에서 자동차가 고장나게 되어 수리하고자 할 때 자동차를 들어올릴 수 있도록 해주는 잭(Jack)을 항상 비치하고서 운행하게 된다.In general, a car breaks down in a car, and a jack (Jack) is always provided so that the car can be lifted when it is to be repaired.
즉, 자동차를 운행하는 도중에 타이어가 펑크나거나 운전자가 간단하게 고칠 수 있는 부분이 고장난 경우에 자동차의 트렁크 등에 보관된 잭을 꺼낸 후 자동차의 바닥 부분에서 프레임과 같이 많이 하중을 견딜 수 있는 부분에 잭을 밀어 넣는다.In other words, if the tire is punctured while driving, or if the part that the driver can easily fix is broken, take out the jack stored in the trunk of the car and then put the jack in the bottom part of the car that can withstand a lot of load such as the frame. Push it in.
그리고 잭 레버(Jack lever)를 손으로 돌리게 되면 잭 레버의 회전에 의해 나사봉이 회전하게 되면서 잭을 상부로 이동시키게 되고 땅바닥으로부터 자동차를 서서히 들어올리게 된다.When the jack lever is turned by hand, the screw rod is rotated by the rotation of the jack lever, which moves the jack upwards and gradually lifts the car from the ground.
이와 같이, 자동차를 들어올리기 위해서 사용되는 잭은 펌프의 유압을 이용하는 유압식 잭과 상기한 바와 같이 잭레버를 사용하여 나사봉을 회전시켜 잭을 동작시키는 기계식 잭이 있다.As such, the jacks used for lifting automobiles include hydraulic jacks using the hydraulic pressure of the pump and mechanical jacks for operating the jacks by rotating a screw rod using the jack lever as described above.
그런데, 일반적으로 종래의 잭은 바닥에 닿는 지지대가 고정되어 있어서 경사진 노면에 놓여진 자동차를 들어올리기 위해 사용할 때에는 노면을 수평으로 만들거나 지지대 바닥에 돌덩어리와 같은 물체를 받친 불안한 상태에서 자동차를 들어올려야 하므로 잭을 작동시키는 도중에 자동차가 미끄러지는 것과 같은 매우 위험한 사태가 발생할 수 있는 문제점이 있었다.However, in general, the jack is fixed to the floor is fixed, when used to lift the car placed on the inclined road surface to raise the car in an unstable state to level the road surface or to support the object, such as stone blocks on the floor of the support Therefore, there was a problem that a very dangerous situation such as a car slips while operating the jack.
본 발명은 이러한 점을 감안하여 발명한 것으로서, 자동차 등과 같이 무거운 물체를 들어올려주는 잭에 있어서, 잭을 받쳐주고 일정한 곡률에 의한 환형 곡면의 지지부가 형성된 받침판과, 지지부에 접촉하여 회동하는 회전구 및 회전구의 상부면으로부터 돌출된 환형봉을 갖는 회전체와, 환형봉이 끼워지는 고정구멍이 형성되며 받침판의 나사홈에 볼트에 의해 체결 고정되는 원반형상의 고정체와, 회전체의 환형봉이 삽설되어 볼트에 의해 체결되며 회전체를 지지하면서 잭과 연결된 고정판 등으로 구성된 회전구가 부설된 다용도 잭을 제공하여서 자동차가 경사진 지점에 놓여 있더라도 잭과 받침판 사이에 설치된 회전체에 의해 잭을 용이하게 지지시켜서 자동차를 들어올리도록 하는 것이 목적이다.The present invention has been invented in view of such a point, and in a jack for lifting a heavy object such as an automobile, a support plate supporting a jack and having an annular curved support part formed by a constant curvature, and a rotating tool rotating in contact with the support part And a rotating body having an annular rod protruding from the upper surface of the rotating sphere, a fixing hole into which the annular rod is fitted, and a disk-shaped fixing body fastened and fixed by bolts to a screw groove of the support plate, and an annular rod of the rotating body being inserted into the bolt. By providing a multi-purpose jack, which is fastened by the rotating body composed of a fixed plate connected to the jack while supporting the rotating body, even if the car is placed at an inclined point, the jack is easily supported by the rotating body installed between the jack and the supporting plate. The purpose is to raise the car.
이하 첨부도면 제1도 내지 제3도에 의거하여 본 발명을 상세히 설명하도록 한다.Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 3.
자동차 등과 같이 무거운 물체를 들어올리는 잭(6)에 있어서, 상기 잭(6)을 받쳐주도록 바닥에 닿고 일정한 곡률에 의한 환형곡면의 지지부(1a)가 형성된 받침판(1)과, 상기 지지부(1a)에 접촉하여 회동하는 회전구(2a) 및 회전구(2a)의 상부면으로부터 돌출된 환형봉(2b)을 갖는 회전체(2)와, 상기 환형봉(2b)이 끼워지는 고정구멍(3a)이 형성되며 상기 받침판(1)의 나사공(1b)에 볼트(4)로 체결 고정되는 원반형상의 고정체(3)와, 상기 회전체(2)의 환형봉(2b)이 삽설되어 볼트(7)에 의해 체결되며 회전체(2)를 지지하면서 잭(6)과 연결된 고정판(5) 등으로 구성된 것이다.In the jack 6 for lifting a heavy object such as an automobile, the support plate 1 is formed to contact the floor to support the jack 6 and has an annular curved support 1a formed by a constant curvature, and the support 1a. A rotating body 2a having a rotary ball 2a which rotates in contact with the rotary rod 2b and an annular bar 2b protruding from the upper surface of the rotary ball 2a, and a fixing hole 3a into which the annular bar 2b is fitted. Is formed and the disk-shaped fixing body (3) is fastened and fixed to the screw hole (1b) of the supporting plate (1), and the annular bar (2b) of the rotating body (2) is inserted into the bolt (7) It is fastened by) and is composed of a fixed plate 5 and the like connected to the jack 6 while supporting the rotating body (2).
그리고, 상기 고정체(3)의 고정구멍(3a)의 지름은 상기 회전체(2)의 환형봉(2b)이 사방으로 동작할 수 있도록 환형봉(2b)의 지름보다 조금크게 제작된다.The diameter of the fixing hole 3a of the fixing body 3 is made slightly larger than the diameter of the annular bar 2b so that the annular bar 2b of the rotating body 2 can operate in all directions.
이하 본 발명의 작용·효과를 설명하도록 한다.Hereinafter will be described the operation and effect of the present invention.
먼저 본 발명의 조립과정을 살펴보도록 하면, 고정체(3)와 받침판(1) 사이에 회전체(2)를 위치시켜서 회전체(2)의 환형봉(2b)을 고정체(3)의 고정구멍(3a)에 삽입시킨 후 받침판(1)의 나사공(1b)과 고정체(3)의 체결공(3b)을 서로 일치시켜서 볼트(4)를 관통시켜서 고정체(3)를 받침판(1)에 결합시킨다.First, assembling process of the present invention, by positioning the rotating body (2) between the fixed body (3) and the backing plate (1) to fix the annular bar (2b) of the rotating body (2) of the fixed body (3) After inserting into the hole 3a, the screw hole 1b of the support plate 1 and the fastening hole 3b of the fixing body 3 coincide with each other to penetrate the bolt 4 so that the fixing plate 3 is supported. )
그리고, 고정체(3)로부터 돌출된 회전체(2)의 환형봉(2b)을 잭(6)에 결합된 2개의 고정판(5) 사이에 끼워넣고서 고정판(5)의 관통공(5a)과 회전체(2)의 관통공(2c)을 서로 일치시켜서 볼트(7)를 사용하여 회전체(2)와 고정판(5)을 결합시키게 되면 조립이 완성되어진다.Then, the annular bar (2b) of the rotating body (2) protruding from the fixing body (3) is sandwiched between two fixing plates (5) coupled to the jack (6) and the through hole (5a) of the fixing plate (5) When the through holes 2c of the rotating body 2 are matched with each other to join the rotating body 2 and the fixed plate 5 using the bolts 7, the assembly is completed.
이러한 상태에서 경사진 위치에 자동차가 놓여있을 때 본 발명에 따른 잭레버를 잭(6)에 끼워서 회전시키게 되면 나사봉(8)이 회전하면서 잭(6)이 올라가게 되고 차체를 들어올리게 된다.When the car is placed in the inclined position in such a state that the jack lever according to the present invention is inserted into the jack 6 and rotated, the jack 6 is raised while the screw rod 8 rotates, and the vehicle body is lifted.
이때, 노면이 경사진 관계로 잭(6)이 삐뚤어지게 설치되지만 회전체(2)의 회전구(2a)가 받침판(1)의 지지부(1a)와 고정체(3)에 의해서 회동하게 되므로 받침판(1)이 기울어진 상태에서도 차체를 그대로 상측 방향으로 들어올려주게 된다.At this time, the jack 6 is installed at an acute angle due to the inclined road surface, but since the rotary hole 2a of the rotating body 2 is rotated by the support part 1a and the fixing body 3 of the supporting plate 1, the supporting plate is supported. Even when (1) is inclined, the vehicle body is lifted upward as it is.
따라서, 종래의 잭을 경사진 노면에서 사용하기 위해서는 별도의 물체를 노면에 받치거나 혹은 노면을 고프게 만든 상태에서 잭을 사용하므로서 매우 불편할 뿐만 아니라 위험의 소지를 지니고 있던 것과는 다르게 본 고안의 잭(6)은 환형의 회전구(2a)를 갖는 회전체(2)에 의해 받침판(5)에 대해 잭(6)이 회동되므로서 경사진 노면에 대해서도 노면의 상태를 고려하지 않고서도 용이하게 자체를 들어올리도록 하므로서 운전자에게 편리성과 안전성을 제공하게 해주는 유용한 발명이다.Therefore, in order to use a conventional jack on an inclined road surface, the jack of the present invention is not only very inconvenient but also dangerous because the jack is used in a state where a separate object is supported on the road surface or the road surface is made to be rough. 6) is easily rotated itself without considering the state of the road surface even on the inclined road surface by the jack (6) is rotated with respect to the support plate (5) by the rotating body (2) having an annular rotating hole (2a). It is a useful invention that provides convenience and safety to the driver by lifting it.
