본 발명은 공작물이나 구조물을 들어올리는데 사용되는 잭에 관한 것으로 특히 사용이 용이한 구조를 갖는 나사 잭에 관한 것이다.The present invention relates to jacks used to lift workpieces or structures, and more particularly to screw jacks having an easy-to-use structure.

잭(jack)의 종류로는 나사 잭, 래크 구동 잭, 유압 잭 등이 있다. 그 중에서 가장 단순한 구조를 가지고 있는 나사 잭이 휴대하기 좋은 크기를 가지고 있으며 가격이 낮아 가장 많이 사용되고 있다.Types of jacks include screw jacks, rack drive jacks, hydraulic jacks, and the like. Among them, the screw jack with the simplest structure is the most popular because of its small size and easy to carry.

자동차에는 비상시 차량을 운전자가 손수 관리할 수 있도록 판매시 필수적인 장비와 공구들이 비치하고 있다. 그 중 가장 흔히 발생되는 타이어의 펑크를 대비하여 예비 타이어로 교환할 수 있는 공구들이 있다. 상기 나사 잭의 경우 이와 같은 예비 타이어의 교환시 없어서는 안될 필수적인 작업장비이다.Cars are equipped with essential equipment and tools for sale to help drivers manage their vehicles in an emergency. Among the most common tire punctures are tools that can be replaced with spare tires. In the case of the screw jack is an essential work equipment that is indispensable when replacing such a spare tire.

제1도는 상술한 종래의 나사 잭의 구조를 나타낸 것으로, 상기 나사 잭은 하부에 지면에 고정되는 지지판과 상부에 차체에 고정되는 고정블럭(2)과, 상기 지지판(1)과 고정블럭(2) 사이에 나사축(3)의 회전에 의해 상승 또는 하강되도록 힌지로 연결된 마름모꼴의 작동아암(4)으로 구성된다.1 shows the structure of the conventional screw jack described above, wherein the screw jack has a support plate fixed to the ground at the bottom and a fixed block 2 fixed to the vehicle body at the top, and the support plate 1 and the fixed block 2. It consists of a rhombic working arm (4) connected by a hinge so as to be raised or lowered by the rotation of the screw shaft (3).

그리고 상기 나사축(3)은 작동아암(4)의 양측 힌지축 중심을 관통하여 연결되며, 일단에는 잭을 동작시키기 위한 잭 핸들이 연결될 수 있는 머리(3a)가 형성되어 있다.The screw shaft 3 is connected through the centers of both hinge shafts of the operating arm 4, and at one end, a head 3a is formed to which a jack handle for operating the jack can be connected.

제2도는 상술한 구조를 갖는 종래 나사 잭의 동작관계를 설명하면 다음과 같다.2 is a view illustrating the operation relationship of the conventional screw jack having the above-described structure as follows.

먼저, 나사 잭을 사용할 위치에 세운 후 잭 핸들(100)의 소켓이 나사축(3)의 머리(3a)에 연결되도록 한다. 이 상태에서 잭 핸들(100)을 회전시키면 나사축(3)이 함께 회전하면서 작동아암(4)이 고정블록(2)을 상승되어 차체(200)를 들어올리게 된다.First, the screw jack is set in a position to be used so that the socket of the jack handle 100 is connected to the head 3a of the screw shaft 3. In this state, when the jack handle 100 is rotated, the operating arm 4 lifts the fixing block 2 while the screw shaft 3 rotates together to lift the vehicle body 200.

상술한 동작과정에서 잭 핸들(100)이 연결되는 나사축(3)의 머리 부위가 지면에 가깝게 위치하기 처음 조작시 잭 핸들(100)의 손잡이 부위가 지면에 간섭되기 때문에 일정 각도씩 회전시키고 다시 분리시킨 후 다시 연결하여 회전시키는 동작을 반복하여야 한다.In the above-described operation, the head of the screw shaft 3 to which the jack handle 100 is connected is located close to the ground. Since the handle portion of the jack handle 100 interferes with the ground during the first operation, it rotates at an angle and then again. After disconnecting, reconnecting and rotating should be repeated.

펑크로 인한 예비 타이어의 교환이 보통 도로와 인접한 노상에서 행해진다는 것을 감안한다면 이러한 작업상의 불편은 사용자에게 짜증을 더해 주게 된다.Considering that the replacement of spare tires due to puncture is usually done on the road adjacent to the road, this work inconvenience is annoying for the user.

즉, 종래의 나사 잭은 구조상 작업성이 좋지 않아 작업시간이 길어지는 문제점이 있었다.That is, the conventional screw jack has a problem in that the work time is long due to poor workability in structure.

본 발명은 상술한 문제점들을 해소하기 위해 제안된 것으로, 특히 잭의 작업을 용이하도록 한 나사 잭을 제공하는데 목적이 있다.The present invention has been proposed to solve the above problems, and an object thereof is particularly to provide a screw jack to facilitate the operation of the jack.

상기 목적을 달성하기 위한 본 발명의 특징에 의하면, 나사 잭은 나사축에 의해 동작되는 작동아암을 구비하고, 또한 상기 나사축의 일단에 형성한 제1베벨기어와, 상기 제1베벨기어에 일단이 치합되는 제2베벨기어와 타단에 잭 핸들에 연결되는 머리가 축으로 연결되는 작동부재와, 상기 작동아암의 고정과 작동부재가 상기 제1베벨기어와 상부방향으로 소정각도를 갖도록 고정하는 고정부재를 포함한다.According to a feature of the present invention for achieving the above object, a screw jack has a working arm operated by a screw shaft, and the first bevel gear formed on one end of the screw shaft, and one end of the first bevel gear An actuating member having a head connected to the jack handle at the other end and a second bevel gear to be engaged with the shaft, and a fixing member for fixing the actuating arm and the actuating member to have a predetermined angle upward with the first bevel gear. It includes.

이하 본 발명의 바람직한 실시예 및 작용·효과를 첨부된 도면에 따라서 상세히 설명한다.Hereinafter, preferred embodiments of the present invention, actions and effects will be described in detail with reference to the accompanying drawings.

제3도는 본 발명에 따른 나사 잭의 전체적인 구성을 나타낸 것이다.Figure 3 shows the overall configuration of the screw jack according to the present invention.

상기 나사 잭은 나사축(40)의 일단에 베벨기어(41)를 형성하고, 이 베벨기어에 맞물리도록 소정각도를 두고 연결된 조작부재(60)와, 이 조작부재의 고정과 작동아암(20)을 연결하는 고정부재로 구성된다.The screw jack forms a bevel gear 41 at one end of the screw shaft 40, and is connected to the operation member 60 at a predetermined angle to engage the bevel gear, and the fixing and operating arm 20 of the operation member. It consists of a fixing member for connecting.

상기 조작부재(60)는 일단이 나사축(40)에 형성된 베벨기어(41)에 치합되는 베벨기어(61)가 형성되고, 타단이 잭 핸들에 연결되는 머리(63)가 회전축(62)으로 연결된 구조를 갖는다.The operation member 60 is formed with a bevel gear 61, one end of which is engaged with the bevel gear 41 formed on the screw shaft 40, the other end is connected to the jack handle head 63 is the rotation shaft 62 It has a connected structure.

상기 고정부재는 중심에 나사축(40)이 회전되도록 고정하는 고정공(51a)과 양측에 작동아암(20)을 연결하는 힌지축(21)을 고정하는 좌우에 연결된 힌지블래킷(51)과, 상기 나사축의 베벨기어(41)가 위치한 힌지블래킷(51)의 일측에 용접으로 고정되고 상기 조작부재(60)의 회전축(62)이 연결되어 고정되는 고정공(52a)이 형성된 조작부재 고정블래킷(52)으로 구성된다.The fixing member has a hinge hole (51) connected to the left and right fixing the fixing hole (51a) for fixing the screw shaft 40 to rotate in the center and the hinge shaft (21) connecting the operation arm (20) on both sides; Fixing operation member having a fixing hole (52a) is fixed by welding to one side of the hinge bracket (51) where the bevel gear (41) of the screw shaft is located and the rotating shaft (62) of the operation member (60) is connected and fixed. It consists of the bracket 52.

상기 조작부재의 축(52)은 고정블래킷에 형성된 고정공(52a)에 끼워져 스냅링(53)에 의해 이탈되지 않도록 고정된다.The shaft 52 of the operation member is fitted into the fixing hole 52a formed in the fixing bracket and is fixed so as not to be separated by the snap ring 53.

제3도는 상기 조작부재 및 고정블래킷과 나사축 일단의 베벨기어의 연결상태를 나타낸 것으로, 조작부재는 상기 나사축과 소정의 각도로 경사지게 고정된다.3 is a view illustrating a state in which the operation member, the fixing bracket, and the bevel gear at one end of the screw shaft are inclined at an angle with the screw shaft.

미설명 부호 10과 30은 각각 받침편과 고정블록을 나타낸 것이다.Reference numerals 10 and 30, respectively, refer to the support piece and the fixed block, respectively.

상술한 구조를 갖는 본 발명의 동작관계를 제5도를 참고로 설명하면 다음과 같다.Referring to Figure 5 the operation relationship of the present invention having the above structure is as follows.

먼저 종래의 나사 잭 사용방법과 동일한 방법으로 차체하부에 위치시킨 후 잭 핸들(100)의 소켓(110)을 상기 조작부재의 머리(63)에 연결한다. 이때 상기 잭 핸들(100)은 연결된 위치에서 지면과 소정의 각도를 이루게 되므로 조작시 잭 핸들(100)의 손잡이 부위(110)가 지면에 간섭되지 않게 된다. 따라서 안정된 작업으로 차체를 들어올릴 수 있어 작업시간이 단축된다.First, it is located under the vehicle body in the same manner as the conventional screw jack method, and then connects the socket 110 of the jack handle 100 to the head 63 of the operation member. At this time, since the jack handle 100 forms a predetermined angle with the ground in the connected position, the handle portion 110 of the jack handle 100 does not interfere with the ground during operation. Therefore, it is possible to lift the vehicle body in a stable operation, reducing the work time.

이와 같이 본 발명은 타이어의 교체와 같은 다소 번거로운 작업시 차량의 리프팅을 간편하게 해줌으로써 작업자의 불편을 덜고 작업을 신속하게 할 수 있는 이점이 있다.As such, the present invention has the advantage of reducing the inconvenience of the operator and speeding up the work by simplifying the lifting of the vehicle during the cumbersome work such as replacement of the tire.
