Description
본 고안은 유압잭에 관한 것으로서, 보다 상세히는 유압잭의 몸체와 손잡이의 결합방식을 개선하여 내구성 및 정밀도 그리고 생산성을 향상시킨 유압잭의 손잡이 조립구조에 관한 것이다.The present invention relates to a hydraulic jack, and more particularly to a handle assembly structure of the hydraulic jack to improve the durability and precision and productivity by improving the coupling method of the body and the handle of the hydraulic jack.
통상적으로, 유압잭은 유체를 이용하여 무거운 물체를 원하는 높이로 들어 올리거나 지지하는 작업보조기구로서, 유압에 의해 중앙의 램이 수직 작동하게 된다.Typically, the hydraulic jack is a work aid for lifting or supporting a heavy object to a desired height using a fluid, the hydraulic ram is to vertically operate the central ram.
그리고 유압잭은 통상 작업자가 손으로 운반하기 용이하도록 본체에 손잡이가 달려 있으며, 볼트 체결방식과 용접 결합방식에 의해 손잡이가 본체에 부착된다.And the hydraulic jack is usually equipped with a handle on the body so that the operator can easily carry by hand, the handle is attached to the body by the bolt fastening method and the welding coupling method.
상기 볼트 체결방식은 도 6에서 도시된 것처럼 손잡이(24)의 양측단부에 구멍(25)을 구성하고 볼트(26)를 끼우며 유압잭(10＇)의 몸체와 체결시키게 되는 것으로 장시간 사용시 볼트의 나사 결합부분이 마모되어 손잡이(24)가 떨어져 나가는 문제점이 있고, 손잡이(24)의 구성상 주물에 의해 성형하게 되면서 제조단가를 높이는 문제점이 잇다. In the bolt fastening method, as shown in FIG. 6, holes 25 are formed at both ends of the handle 24, the bolts 26 are fitted, and the bolts are fastened to the body of the hydraulic jack 10. There is a problem that the engaging portion is worn out to fall off the handle 24, there is a problem to increase the manufacturing cost while being molded by the casting on the configuration of the handle (24).
그리고 용접 결합방식은 용접 시 고온에 의해 가열되면서 본체는 열변형이 발생되고, 정밀성이 떨어지면서 품질 및 성능을 저하시키며, 생산성을 높일 수 없다.And the welding coupling method is heated by high temperature during welding, the main body heat deformation occurs, the precision is degraded, the quality and performance is reduced, and productivity cannot be increased.
본 고안은 상술한 종래의 문제점을 극복하기 위한 것으로, 본 고안의 목적은 유압잭의 몸체와 손잡이의 체결방식을 개선하여 용접에 의한 열변형을 방지하면서 정밀도를 유지하고 내구성을 향상시키며, 생산성을 높일 수 있는 유압잭의 손잡이 조립구조를 제공한다. The present invention is to overcome the above-mentioned problems, the object of the present invention is to improve the fastening method of the body and the handle of the hydraulic jack to prevent the thermal deformation by welding, while maintaining the precision and improve the durability, increase the productivity It provides a handle assembly structure of the hydraulic jack.
상기와 같은 목적을 달성하기 위하여 본 고안은, 유압잭 몸체의 일측에 나사구멍(17)과 원통형 구멍(18)을 각각 상/하로 형성시키며, 상기 몸체와 체결되는 손잡이(20)는 "ㄷ" 형상으로 밴딩된 일체형으로써 일측 단부에 나사부(22)가 형성되어 몸체의 나사구멍(17)으로 체결되며, 타측 단부에는 끼움부(24)가 형성되어 몸체의 구멍(18)에 억지끼움으로 조립됨을 특징으로 한다.In order to achieve the above object, the present invention, the screw hole 17 and the cylindrical hole 18 is formed on each side of the hydraulic jack body up / down, the handle 20 is fastened to the body is a "c" shape As a united body is bent by the screw portion 22 is formed at one end is fastened to the screw hole 17 of the body, the other end is fitted with a fitting portion 24 is characterized in that it is assembled by interference fit in the hole 18 of the body It is done.
이하 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1과 도 2는 본 고안에 따른 유압잭의 손잡이 조립구조를 도시한 분해상태와 조립상태의 사시도이고, 도 3 내지 도 5는 본 고안에서 유압잭의 몸체에 손잡이가 조립되는 상태를 도시하고 있다.1 and 2 are a perspective view of the disassembled state and assembled state showing the handle assembly structure of the hydraulic jack according to the present invention, Figures 3 to 5 shows a state in which the handle is assembled to the body of the hydraulic jack in the present invention.
도면에 따르면, 유압잭(10)은 내부에 설치되어 상부로 수직 작동하는 램(14)과 상기 램을 작동시키기 위해서 몸체 하부에는 호스연결구(16)를 두고 외부의 유압장치와 호스를 연결하여 유체를 공급한다. According to the drawings, the hydraulic jack 10 is installed inside the ram 14 to operate vertically upward and the hose to the lower portion of the body to operate the ram 16 to connect the external hydraulic device and the hose to connect the fluid Supply.
그리고 상기 유압잭(10)의 일측면에는 손잡이(20)가 부착된다.And the handle 20 is attached to one side of the hydraulic jack (10).
상기 손잡이(20)를 부착하기 위해 몸체(12)의 일측 상부에는 나사구멍(17)을 형성하고 있으며 그 하부에는 원형의 구멍(18)을 형성시키고 있다. In order to attach the handle 20, a screw hole 17 is formed at an upper side of the body 12, and a circular hole 18 is formed at the bottom thereof.
그리고 상기 손잡이는 "ㄷ" 형상으로 밴딩 된 일체형으로써 일측 단부에 나사부(22)가 형성되어 몸체의 나사구멍(17)으로 체결되며, 타측 단부에는 끼움부(24)가 형성되어 몸체의 구멍(18)에 억지끼움으로 조립된다.And the handle is a one-piece banded in the "c" shape is formed with a screw portion 22 at one end is fastened to the screw hole 17 of the body, the other end is formed with a fitting portion 24 is formed in the hole 18 ) Is assembled by interference fit.
이때, 상기 손잡이의 나사부(22)가 있는 절곡부 "B"는 둔각으로서 나사체결시에 타측 끼움부가 몸체에 걸리지 않고 회전시킬 수 있게 된다.At this time, the bent portion "B" with the threaded portion 22 of the handle is an obtuse angle so that the other fitting portion can be rotated without being caught by the body at the time of screwing.
도 3내지 도 5에 의해서 손잡이(20)가 몸체(12)에 결합되는 동작을 설명한다.3 to 5 will be described the operation in which the handle 20 is coupled to the body 12.
먼저, 손잡이의 나사부(22)를 몸체(12)의 나사구멍(17)에 체결시킨다. 나사부가 있는 손잡이의 밴딩부는 수직 이상의 충분한 각도로 밴딩되어 회전시에 끼움부방향의 끝이 몸체에 걸리지 않고 회전될 수 있다. 이후 끼움부(24)를 고무망치 등으로 충격을 가하여 몸체(12)의 구멍(18)으로 삽입시킨다. 따라서 끼움부(24)는 구멍(18)에 억지끼움 조립되면서 빠지지 않게 되고 견고하게 조립된다. First, the screw portion 22 of the handle is fastened to the screw hole 17 of the body 12. The bending portion of the threaded handle can be bent at a sufficient angle above the vertical so that the end of the fitting direction can rotate without being caught by the body during rotation. Thereafter, the fitting portion 24 is inserted into the hole 18 of the body 12 by applying an impact with a rubber hammer or the like. Therefore, the fitting portion 24 is not assembled while being tightly fitted into the hole 18, and is firmly assembled.
이상으로 살펴본 바와 같이, 본 고안에 따른 유압잭의 손잡이 조립구조는. 용접에 의한 변형의 문제점을 개선하고, 별도의 볼트가 없이 간단하게 체결되면서 정밀도를 유지하고 내구성을 향상시키며, 생산성을 높일 수 있는 효과가 있다.As described above, the handle assembly structure of the hydraulic jack according to the present invention. It improves the problem of deformation due to welding, maintains precision, improves durability, and increases productivity while being simply fastened without a separate bolt.
