본 고안은 샷타휘일에 관한 것이다.The present invention relates to a shotta wheel.
종래에도 샷타휘일은 있었으나 얼마 사용하지 못하여 샷타휘일내부에 내장된 베어링이 이탈되어 사용치 못하게 되고 스프링 고정구를 외형체 주연부에 천공하여 스프링을 고정하였기 때문에 스프링이 샷타휘일의 회전하는 회전범위보다 튀어나오게 되어 스프링이 자주 이탈되고 샷타휘일이 차지하는 면적이 크게되는 등에 불편한 점이 있었다. 본 고안은 이러한 점을 감안하여 샷타휘일내부에서 베어링을 지지하는 내통 일측에 돌출부를 형성시키므로서 하부베어링로형성구의 일단이 돌출부에 걸리게 되므로 내부의 베어링이탈을 방지하게 되고, 외형체의 절곡된 주연부에 V형의 홈을 형성하여 V형홈의 일면에 스프링고정구를 천공하므로서 스프링이 외부로 노출이 되지 않으므로 스프링의 이탈을 방지하고 샷타휘일이 차지하는 면적을 적게하여 주는 등에 잇점이 있게한 것으로 첨부도면에 의거 상세히 설명하면 다음과 같다.Although there was a shot wheel in the past, the bearing built into the shot wheel could not be used because it was not used for a while, and the spring was fixed to the periphery of the outer body to fix the spring so that the spring popped out of the rotating range of the shot wheel. As a result, the spring was frequently dislodged and the area occupied by the shotgun wheel became large. In view of the above, the present invention forms a protrusion on one side of the inner cylinder supporting the bearing in the shot wheel drive, so that one end of the lower bearing furnace is caught on the protrusion, thereby preventing the bearing from falling inside, and the bent peripheral portion of the outer body. V-shaped grooves are formed on the surface of the V-shaped grooves so that the springs are not exposed to the outside, so the springs are not exposed to the outside. The detailed description is as follows.
상부베어링로형성구(5)와 하부베어링로형성구(6)를 결합하여 그 내부에 베어링(4)을 내장시킨 것을 고정구(7)로 고정하고 이를 외부에서 리벳(9)으로 외형체 (8)(8')를 결합하여 고정한 것에 있어서 외형체(8)의 절곡된 주연부에 V형홈(10)(10')(10'')을 형성하여 V형홈(10)(10)(10'')의 일면에 스프링고정구(11)(11')(11'')를 각각 천공하고 내통(1)과 하부베어링로형성구(6)와의 접촉부 끝단에 돌출부(3)를 돌출시켜서 된 것이다.The upper bearing furnace forming tool 5 and the lower bearing furnace forming tool 6 are combined to fix the bearing 4 embedded therein with the fixture 7, and the outer body with the rivet 9 from the outside (8). V 'grooves 10, 10' and 10 'are formed on the bent periphery of the outer body 8 by combining and fixing 8'). The spring fixtures 11, 11 'and 11 " are drilled on one surface thereof, respectively, and the protrusions 3 are protruded at the end of the contact portion between the inner cylinder 1 and the lower bearing furnace forming tool 6).
이와같이 구성된 본 고안은 외형체(8)의 절곡된 주연부에 V형홈(10)(10')(10'')을 형성하여 V형홈(10)(10')(10'')의 일면에 각각 스프링고정구(11)(11')(11'')를 천공하여 이에 스프링을 고정시키므로서 샷타휘일이 회전하게 될때 회전반경이 적게 되므로 스프링이 외부의 다른 것에 걸리는 일이 없게되며 하부베어링로 형성구(6)와 내통(1)과의 접촉면의 끝단에 돌출부(3)를 돌출시키므로서 베어링(4)이 회전하며 외부로 이탈되는 것을 내통(1)에 돌출된 돌출부(3)가 막게 되므로 샷타호일 사용시 베어링(4)이 이탈되어 사용치 못하게 되는 경우 등을 제거시킨 유용한 고안인 것이다.The present invention configured as described above forms V-shaped grooves 10, 10 ', 10' 'on the bent periphery of the outer shell 8, respectively, on one surface of the V-shaped grooves 10, 10', 10 ''. By fixing the springs by drilling the spring fixtures 11, 11 ', and 11' ', the radius of rotation is reduced when the shot wheel is rotated so that the spring is not caught by other external parts. Since the bearing 4 rotates by protruding the protrusion 3 at the end of the contact surface between the inner cylinder 1 and the inner cylinder 1, the protrusion 3 protruding from the inner cylinder 1 is prevented from being shot out. It is a useful design that removes the case when the bearing 4 is not used due to one use is removed.
