제2도는 제1도의 종단면도이다.2 is a longitudinal cross-sectional view of FIG.

본 고안은 합성수지제 푸울리 본체의 외주면에 요입홈을 만들어 그 내부에 열경화성수지제 보강륜을 매설하므로써 가볍고 내구적이며 충격흡수가 용이한 실용적 푸울리가 되게한 것이다.The present invention is made of a hollow groove on the outer circumference of the synthetic PUley body, and buried a thermosetting resin reinforcement wheel therein to be a lightweight, durable and easy to absorb impact.

종래의 정경기용 합성수지제 푸울리는 전체가 열경화성 수지인 백크라이트수지 성형물이기 때문에 무게도 무겁고 가격도 고가일뿐 아니라, 경직성이 과대하여 충격을 받으면 쉽게 파손되는 결점이 있었다.Conventional pooling agent made of synthetic resin for conventional warships, because the whole is a thermosetting resin, the backlight resin molding is not only heavy weight and expensive, but also has a defect that is easily damaged when subjected to shock due to excessive rigidity.

본 고안은 위와 같은 종래의 결점을 시정하기 위하여 안출한 것으로 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention is described in detail based on the accompanying drawings to devise to correct the above conventional defects as follows.

열가소성 합성수지제인 폴리푸로피렌수지로써 푸울리 본체(1)를 성형하고, 원주면에 중앙부로 요입홈(1')을 만들어 그 내부에 열경화성수지인 백크라이트 수지로 성형된 보강륜(3)을 매설하되 보강륜(3)은 내주면으로 형성된 내향돌륜(3') 양측면에 결착요홈(5)과 결착돌재(5')를 형성하여 합성수지액이 효과적으로 피복 응고되게하고, 중심관(2)의 양측외주에는 수개의 신축홈(2")을 형성시킨 구조이다.The Puli body (1) is molded from polypropylene resin made of thermoplastic synthetic resin, and the recessed groove (3) formed in the center is formed on the circumferential surface with a recessed groove (1 ') in the center thereof, and the inner part of the reinforcement wheel (3) formed of the thermosetting resin is made of the resin. However, the reinforcing wheel (3) forms a binding groove (5) and the binding stone (5 ') on both sides of the inward protrusion (3') formed as the inner peripheral surface to effectively coat the synthetic resin coating, both sides outer circumference of the center tube (2) Has a structure in which several expansion grooves 2 "are formed.

이와같이된 본 고안은 푸울리 몸체는 열가소성 합성수지제이므로 단단하고 내마모성이 클뿐아니라 내열성이므로 벨트와 접촉될때 내구적이고 쉽게 닳지 않으며, 변형이 방지되는 이점이 있고, 충격을 받으면 본체(1)에서 흡수하게 되어 파열되는 율이 적으며, 본체(1)와 보강륜(3)은 매설부에 결착홈(5)과 결착돌기(5')가 있어서 결착력이 크므로 성형된 후에 이완되거나 해리될 염려가 없고, 중심관(2)에도 신축홈(2")이 형성되어서 축봉에 푸울리를 삽입할 때 작업이 용이한 잇점이 있는등의 실용성이 있는 것이다.The present invention has the advantage that the pulley body is made of thermoplastic synthetic resin, not only hard and wear-resistant, but also heat-resistant, durable and not easily worn when contacted with the belt, and prevents deformation, and is absorbed by the body 1 when impacted. The rate of rupture is small, and the main body 1 and the reinforcement wheel 3 have a binding groove 5 and a binding protrusion 5 'in the buried portion, so that the binding force is large, so there is no fear of loosening or dissociation after molding. The center tube 2 also has a telescopic groove 2 ", which has practical advantages such as easy operation when inserting a pulley into the shaft.
