To be configured.

상기한 바와 같이 구성된 본 발명의 렌치(1)를 이용하여 자키(20)를 작동시켜 타이어를 교체하는 작업을 일례로 하여 그 작동상태를 설명한다.The operation state will be described taking an operation of replacing a tire by operating the jockey 20 using the wrench 1 of the present invention configured as described above as an example.

먼저 도면 도 3 (a), (b)에 도시와 같이 자키(20)의 일측으로 노출된 작동봉(21)의 결합판체(23)에 관통 형성된 헤드삽입공(24)에 렌치(1)의 렌치핸들(3) 말단부에 형성된 가압판체(4)의 상면으로 돌출되도록 고정된 결합핀(10)의 헤드부(11)를 삽입시킨다.First, as shown in FIGS. 3A and 3B, the wrench 1 is inserted into the head insertion hole 24 formed through the coupling plate body 23 of the operating rod 21 exposed to one side of the jockey 20. The head portion 11 of the coupling pin 10 fixed to protrude to the upper surface of the pressure plate body 4 formed on the distal end of the wrench handle (3) is inserted.

상기 작동봉(21)과 렌치(1)가 동일한 수평선상에 위치하도록 한 후, 렌치(1)를 앞쪽으로 당기면, 결합핀(10)의 헤드부(11) 하측에 형성된 사각핀부(12)의 단축(T3)가 연결통로(26)를 통과하여 사각핀결합공(25)으로 진입하게 된다.After the operating rod 21 and the wrench 1 are positioned on the same horizontal line, and the wrench 1 is pulled forward, the square pin portion 12 formed below the head portion 11 of the coupling pin 10 is pulled out. The short axis T3 passes through the connection passage 26 to enter the square pin coupling hole 25.

상기와 같은 수단으로 렌치(1)를 자키(20)의 작동봉(21)과 결합한 상태에서 자키(20)를 자동차의 차체 하부에 진입시켜 프레임을 받치도록 한 후, 렌치(1)의 렌치헤드(2)를 잡고 회전시킴으로써 작동봉(21)을 작동시키는 것이다.After the wrench 1 is engaged with the operating rod 21 of the jockey 20 by the above means, the jockey 20 enters the lower part of the vehicle body to support the frame, and then the wrench head of the wrench 1 (2) by holding and rotating the operating rod 21 to operate.

상기한 렌치헤드(2)를 손으로 잡고 작동봉(21)을 회전시켜 자키를 작동시키는 동작을 도 4 (a), (b)를 참고하여 구체적으로 설명하면, Referring to Figure 4 (a), (b) to operate the jockey by holding the wrench head (2) by hand to rotate the operating rod 21 will be described in detail,

작동봉(21)과 동일 수직선상에 위치한 렌치(1)를 평면에서 보았을 때, 작동봉(21)의 결합판체(22) 좌측으로 90° 각도로 회전시킨다.When the wrench 1 positioned on the same vertical line as the operating rod 21 is viewed in a plan view, the wrench 1 is rotated at an angle of 90 ° to the left side of the coupling plate body 22 of the operating rod 21.

이때, 결합판체(23)의 사각핀결합공(25)에 삽입되어 있는 결합핀(10)의 사각핀부(12)도 회전하여 연결통로(26)와 직각을 이루게 되어 결합핀(10)의 이탈을 방지하게 되는 것이다. At this time, the square pin portion 12 of the coupling pin 10 inserted into the square pin coupling hole 25 of the coupling plate body 23 also rotates to form a right angle with the connection passage 26 to disengage the coupling pin 10. Will be prevented.

이어서 렌치(1)를 나사조임방향인 시계방향으로 180°회전시켜 작동봉(21)을 180°회전시켜 자키(20)를 일정 높이로 상승시키고, 렌치(1)를 다시 지면과 수평상태로 180°회전시킨 후, 나사조임방향으로 180° 회전시키는 수단을 반복함으로써 자키(20)를 작동시켜 자동차를 일정한 높이까지 들어올리게 되는 것이다.Subsequently, the wrench 1 is rotated 180 ° clockwise in the direction of screw tightening, the operating rod 21 is rotated 180 ° to raise the jockey 20 to a certain height, and the wrench 1 is again rotated 180 degrees to the ground. After the rotation, by repeating the means to rotate 180 ° in the screw tightening direction to operate the jockey 20 is to lift the car to a certain height.

타이어의 정비가 완료된 후에 자키(20)를 하강시켜 자동차를 내리는 작동은 비교적 적은 힘으로도 가능하므로, 자키(20)의 작동봉21)에 결합한 렌치(1)를 상술한 수단을 통하지 않고, 렌치(1)를 작동봉(21)과 일직선상으로 연결하고, 렌치헤드(2)를 회전시키는 동작만으로도 자키(20)의 하강작동이 이루어지는 것이다.Since the operation of lowering the vehicle by lowering the jockey 20 after the maintenance of the tire is completed is possible even with a relatively small force, the wrench 1 coupled to the actuating rod 21 of the jockey 20 does not go through the aforementioned means. The lowering operation of the jockey 20 is performed only by connecting (1) in a straight line with the operating rod 21 and rotating the wrench head 2.

본 발명에 있어서 렌치(1)의 가압판체(4)에 고정되는 결합핀(10)은 그 모양을 3단으로 구성한 것을 적용할 수 있다.In the present invention, the coupling pin 10 fixed to the pressure plate body 4 of the wrench 1 can be applied to the configuration consisting of three stages.

즉, 첨부 도면 도 8에 도시된 바와 같이 결합핀(100)을 헤드부(101)와, 이 헤드부(101)의 지름(T1)보다 작은 지름(T2)을 가진 결합부(102), 이 결합부(102)의 지름(T2)보다 작은 지름(T3)의 통과부(103), 이 통과부(103)보다 작은 지름(T4)을 가진 리벳부(104)로 구성한 다단의 결합핀(100)을 적용할 수 있다.That is, as shown in FIG. 8, the coupling pin 100 includes a coupling portion 102 having a head portion 101 and a diameter T2 smaller than the diameter T1 of the head portion 101. Multi-stage coupling pin 100 composed of a passage portion 103 having a diameter T3 smaller than the diameter T2 of the coupling portion 102 and a rivet portion 104 having a diameter T4 smaller than the passage portion 103. ) Can be applied.

이러한 실시예에의한 결합핀(100)은 자키(20)의 결합판체(23)에 관통 형성된 헤드삽입공(24)으로 헤드부(101)가 삽입되고, 이어서 연결통로(26)를 통과할 수 있는 지름(T3)을 가진 통과부(103)로 연결통로(26)를 통과하고, 최후에 사각핀결합공(25)에는 상기 결합핀(100)의 헤드부(101) 아래에 형성된 결합부(102)가 결합되어 사각핀결합공(25)에서의 이탈을 방지하도록 하는 것이다.The coupling pin 100 according to this embodiment is the head portion 101 is inserted into the head insertion hole 24 formed through the coupling plate body 23 of the jockey 20, and then pass through the connection passage 26 Passing through the connecting passage 26 to the passage portion 103 having a diameter (T3), and finally in the square pin coupling hole 25, the coupling portion formed below the head portion 101 of the coupling pin 100 102 is coupled to prevent the departure from the square pin coupling hole (25).

본 발명에 적용되는 자키(20)의 작동봉(21)에 형성되는 결합판체(23)의 헤드삽입공(24), 사각핀결합공(25) 및 연결통로(26)의 구성은 첨부 도면 도 5 (a), (b)에 도시된 바와 같이 구성할 수 있다.The configuration of the head insertion hole 24, the square pin coupling hole 25 and the connection passage 26 of the coupling plate body 23 formed on the operating rod 21 of the jockey 20 applied to the present invention is shown in the accompanying drawings It may be configured as shown in 5 (a), (b).

즉, 헤드삽입공(24)과 사각핀결합공(25)이 교집합을 이루도록 형성하되, 상기 교집합이 이루어지는 교차부분의 폭(t3)이 결합핀(10)에 형성된 사각핀부(12)의 단축(T3)이 통과하할 수 있는 정도의 폭(t3)을 가지도록 형성할 수 있는 것이다.That is, the head insertion hole 24 and the square pin coupling hole 25 is formed to make the intersection, the width (t3) of the intersection portion where the intersection is made of the short axis of the square pin portion 12 formed on the coupling pin 10 ( It can be formed to have a width (t3) to the extent that T3) can pass.

또한, 첨부 도면 도 9에 도시된 바와 같이 상기 자키(20)의 자키작동봉(21) 에 형성되는 결합판체(23)에, 결합핀(10)의 사각핀부(12)의 장축(T2)보다 미세하게 큰 지름(t2)을 가진 사각핀결합공(25') 만을 관통 형성하고, 이 사각핀결합공(25')과 결합판체(23)의 전면부를 절결하여 절결통로(26')를 형성하되, 이 절결통로(26')의 폭(t3)이 사각핀부(12)의 단축(T3)보다 미세하게 큰 정도로 형성하여, 자키(1)에 형성된 결합핀(10)을 결합판체(23)의 전방부에서 삽입하는 수단을 제공할 수 있다.In addition, as shown in FIG. 9, in the coupling plate body 23 formed on the jockey operation rod 21 of the jockey 20, a longer axis T2 of the square pin portion 12 of the coupling pin 10 is provided. Only a rectangular pin coupling hole 25 'having a fine diameter t2 is formed to penetrate through it, and the front portion of the square pin coupling hole 25' and the coupling plate body 23 is cut to form a notch passage 26 '.
