Description

분무기용 플런저 조립구조{DEVICE FOR ASSEMBLING PLUNGER SPRAYER}Plunger assembly structure for sprayer {DEVICE FOR ASSEMBLING PLUNGER SPRAYER}

본 발명은 방제나 양수에 이용하는 동력 분무기용 플런저 조립구조에 관한 것이다.The present invention relates to a plunger assembly structure for a power sprayer used for controlling or pumping water.

동력분무기는 크랭크축을 회전하여 플런저를 실린더내에서 왕복운동하고 흡수밸브에 흡수하여 토출밸브에서 토출하는 구성인데 플런저는 부식작용과 산화력이 높은 약제와 접촉하므로 쉽게 산화 부식되어 그 수명이 오래가지 못하는 불편이 있다.Power sprayer rotates the crankshaft to reciprocate the plunger in the cylinder, absorbs it into the absorption valve and discharges it from the discharge valve. Plunger is easily oxidized and corroded because it comes into contact with chemicals with high corrosion and oxidizing power. There is this.

따라서 내부식성인 세라믹을 채용하고 있으나 크랭크축과의 부착이 여의치 못해 실용화가 될 수 없는 현실에 있다.Therefore, although corrosion resistant ceramics are used, they cannot be put to practical use because they cannot be attached to the crankshaft.

본 발명은 상기와 같은 불편을 해소시키기 위해 플런저 본체를 세라믹제로 성형하고 크랭크축과의 결합되는 부분에 비철금속제 연결구를 결합시켜서 접착제로 접합함으로써 볼트너트로 된 체결수단을 배제하고 내구적인 접합이 이루어지게 한 것이다.The present invention forms a durable plunger by excluding the fastening means made of bolt nuts by gluing the plunger body with a ceramic and joining the non-ferrous metal connector to the portion to be joined with the crankshaft to the adhesive to eliminate the inconvenience as described above. It is lost.

본 발명은 세라믹제 플런저 본체와 크랭크축이 결합되는 곳에 비철금속제(황동)연결구를 접착제로 접합시켜서 일체가 되도록 한 것이다.In the present invention, the non-ferrous metal (brass) connector is bonded to the place where the ceramic plunger main body and the crankshaft are bonded to each other so as to be integrated.

이와 같이 된 본 발명은 세라믹제로 된 플런저 본체와 크랭크축이 결합되는 곳에 비철금속제 연결구를 접합함에 있어서 플런저 본체의 내측단 중심에 형성된 삽입공 내주면에 환상으로 접합홈을 형성하고 연결구에서 플런저 중심공의 삽입공 쪽으로 투입되는 연결봉 외면에 플런저의 삽입공에 형성된 접합홈과 대향하는 위치에 환상으로 접합홈을 형성하고 연결구의 중심부에 접착제 주입공을 형성하여 연결봉 외면에 접합홈에 이르도록 연통공을 형성시켜서 연결구를 플런저 중심에 투입하고 연결봉의 주입공으로 에폭시 접착제를 강제 주입하면 주입된 접착제가 연결봉의 주입공에서 연통공을 통해 접합흠으로 공급되어 플런저 본체와 연결구의 접합홈에 공급되어 응고되므로 서로가 접합되어 일체가 되도록 부착시킬 수 있고 이로 인해 볼트와 너트를 사용하지 않고 플런저와 연결구를 접합시킬 수 있어서 크랭크축의 결합을 원활하게 접합할 수 있는 이점을 얻게 되므로 외부로 체결구의 흔적이 없는 제품이 가능케 된다.The present invention as described above forms a joining groove annularly in the inner circumferential surface of the insertion hole formed in the center of the inner end of the plunger body in joining the non-ferrous metal connector where the ceramic plunger body and the crankshaft are coupled to each other. On the outer surface of the connecting rod which is inserted into the insertion hole, the connecting groove is formed in an annular position at the position opposite to the joining groove formed in the insertion hole of the plunger, and an adhesive injection hole is formed at the center of the connecting hole to form a communicating hole on the outer surface of the connecting rod to reach the joining groove. When the connector is inserted into the center of the plunger and the epoxy adhesive is forcibly injected into the injection hole of the connecting rod, the injected adhesive is supplied through the communication hole from the injection hole of the connecting rod through the joint hole, and is supplied to the joint groove of the plunger body and the connector to solidify. Can be joined together to be integral, Since it is possible to join the plunger and the connector without using a screw, the advantage of smoothly joining the crankshaft coupling is possible, thereby enabling a product without a trace of the fastener to the outside.

그러므로 실린더에 왕복되는 플런저를 세라믹제품으로 제조할 수 있게 되는 효과를 얻게 되며 이로인해 약품에 대하여 내부식성이 좋고 내마모성이 양호한 세라믹제 플런저를 공급할 수 있는 것이다.Therefore, the effect of being able to manufacture the plunger reciprocating to the cylinder can be obtained as a ceramic product, thereby supplying a ceramic plunger with good corrosion resistance and good abrasion resistance to chemicals.

본 발명은 세라믹제 플런저본체(1)에서 크랭크축과 연결되는 내측 중심부에 삽입공(2)을 형성하여 내주면에 일정간격을 두고 환상으로 접합홈(2a)(2b)을 형성하고 삽입공(2)속에 알맞게 끼워지는 연결봉(3a)을 구비하고 비철금속제로 제조되며 크랭크축삽입홈(3b)과 연결핀구멍(3c)을 가지는 연결구(3)의 연결봉(3a)에는 외주면에 플런저 본체의 삽입공 내면에 형성된 환상 접합홈(2a)(2b)과 대응하는 위치에 환상으로 접합홈(4a)(4b)을 형성하고 연결봉(3a)중심에 접착제 주입공(5)을 형성하여 주입공(5)에서 접합홈(4a)(4b)으로 연통공(5a)(5b)을 뚫어서 주입공과 연통공을 통해 에폭시접착액을 주입하여 플런저본체(1)와 연결구(3)를 접합케 한 구성이다.The present invention forms an insertion hole (2) in the inner central portion connected to the crank shaft in the ceramic plunger body (1) to form a joining groove (2a) (2b) in an annular space at a predetermined interval on the inner peripheral surface and the insertion hole (2) The inner surface of the insertion hole of the plunger main body is provided on the outer circumferential surface of the connecting rod 3a of the connector 3 having a connecting rod 3a fitted appropriately into the inside and made of nonferrous metal and having a crankshaft insertion groove 3b and a connecting pin hole 3c. In the injection hole 5 by forming the joining grooves 4a and 4b in annular positions at the positions corresponding to the annular joining grooves 2a and 2b formed in the annular grooves, and forming the adhesive injection holes 5 in the center of the connecting rods 3a. It is a configuration in which the plunger body 1 and the connector 3 are bonded by injecting the epoxy adhesive through the injection hole and the communication hole by drilling the communication holes 5a and 5b into the joining grooves 4a and 4b.
