본 발명은 수도미터기 보호통용 뚜껑에 관한 것으로, 더욱 상세하게는 금속재 철판을 도금시켜 녹이 슬지 않도록 형성시킨 도금판으로 도금 뚜껑을 형성하고, 도금 뚜껑의 상면측과 측면 테두리 내외부측에는 합성수지가 성형되고, 도금 뚜껑의 저면측에는 다수개의 걸림환두부가 형성되어, 동절기에도 합성수지재와 금속재 뚜껑이 이격되거나 파손되지 않고, 뚜껑 저면측에서 녹물이 발생되지 않고, 원재료 대로 재활용이 가능하도록 한 놋물이 생기지 않는 수도미터기 보호통용 보강 뚜껑에 관한 것이다.The present invention relates to a lid for a water meter protective barrel, and more specifically, to form a plating lid with a plate plate formed by plating a metal iron plate so as not to rust, and the synthetic resin is molded on the inner and outer sides of the upper surface and side edges of the plating lid, On the bottom side of the plating lid, a plurality of hook rings are formed, so that the synthetic resin material and the metal lid are not separated or damaged even in winter, no rust is generated on the bottom side of the lid, and no brass can be recycled as raw materials. It relates to a reinforcement cap for a meter protective container.

종래에는, 일반 철판 뚜껑 전체가 합성수지내에 매입되도록 상하부 전체에 합성수지재를 성형시키거나, 도2의 (가)도와 같이, 일반 철판 뚜껑 상면측과 측면에는 합성수지를 성형시키고 저면측은 철판이 노출되도록 형성하거나, 도2의 (나)와 같이, 일반 철판 뚜껑 상면측과 측면에는 합성수지를 성형시키고 저면측은 철판 이 노출되도록 성형시킨 다음, 노출된 철판 뚜껑의 저면측에 별도 제작한 합성수지판을 조립 장착시킨 것이 있었는데, 일반 철판 뚜껑 전체가 합성수지내에 매입되도록 일반 철판 뚜껑의 상하부전체에 합성수지재를 성형시킨 경우에는, 동계절에 합성수지재와 금속재의 신축률 변화가 다르게 되어 쉽게 파손되거나 금이가게 되고, 파손시 철판과 합성수지재의 분리가 어려우므로, 재활용이 안되어, 폐기 처분 해야 하는 폐기물이 발생하게 되었다.Conventionally, a synthetic resin material is molded in the entire upper and lower portions so that the entire iron plate lid is embedded in the synthetic resin, or as shown in FIG. 2, the synthetic resin is formed on the upper side and the side of the ordinary iron plate lid, and the bottom side is formed to expose the iron plate. Alternatively, as shown in (b) of FIG. 2, a synthetic resin is formed on the upper side and the side of the general iron plate lid, and the bottom side is molded so that the iron plate is exposed, and then a separately manufactured synthetic resin plate is assembled to the bottom side of the exposed iron plate lid. When the synthetic resin material was molded on the upper and lower parts of the general iron plate lid so that the entire iron plate lid is embedded in the synthetic resin, the change in the elasticity ratio of the synthetic resin material and the metal material is changed easily during the winter season, and it is easily broken or cracked. It is difficult to separate the steel plate and the synthetic resin in the city. It was.

또한, 일반 철판과 합성수지의 수축 상태가 다르므로 균열을 방지하기 위해 많은 작은 구멍을 형성시키는데 이곳으로 습기가 차게되어 매입된 철판이 녹이 슬게 되고, 이로인해 놋물이 형성되어 떨어지므로 수도미터기 보호통 내부가 불결해지고 오염이 발생하게 되었다.In addition, since the shrinkage of ordinary steel plates and synthetic resins is different, many small holes are formed to prevent cracking. The moisture is filled to make the embedded steel plates rusted, and because of the formation of brass water, the inside of the water meter protector It became unclean and polluted.

또한, 도2의 (가)도와 같이, 철판 뚜껑 상면측과 테두리 외부측에 합성수지재를 성형시키고 철판 뚜껑의 저면측을 노출시킨 것은, 원재료대로 분리하여 재활용은 가능하나, 수도미터기 보호통 내부는 뚜껑 외부측과의 온도차로 결루 형상이 생겨 항상 습기가 형성되는데, 이로 인해 뚜껑의 저면측으로 노출시킨 철판에 습기가 차므로, 놋이 슬어 놋물이 떨어지며, 철판과 합성수지재의 신축율 변화가 다르게 되어, 동계절에는 쉽게 이격되고, 파손이 잘되는 결점이 있었다.In addition, as shown in Fig. 2A, the synthetic resin material is formed on the upper side of the steel plate lid and the outer side of the lid, and the bottom side of the iron plate lid is exposed, and the recycling is possible by separating the raw material into the raw material. Due to the temperature difference between the outside and the condensation shape, moisture is formed all the time. As a result, the iron plate exposed to the bottom side of the lid is filled with moisture, so that the brass falls and the brass drops, and the change in the stretching ratio between the steel plate and the synthetic resin material is different. There was a flaw in the season that was easily spaced apart and well broken.

또한, 도2의 (나)도와 같이 철판 뚜껑 상면측과 측면 테두리 외부측에는 합성수지를 성형시키고, 저면측은 철판이 노출되도록 성형시킨 다음, 노출된 철판 뚜껑의 저면측에 별도 제작한 합성수지판을 조립 장착시킨 것이 있는데, 이는 견고하고 파손시에는 철판과 합성수지를 분리하여 각각 원재료로 재활용이 가능하긴 하 나, 노출된 철판 부위에 별도로 형성시킨 합성수지판을 접착제와 조립 볼트 등을 이용하여 장착시켜야 하므로, 부품을 개별적으로 별도 제조하여야 하고, 또 조립시에 접착제나 조립볼트 등의 많은 조립부품과 조립시간이 소요되어, 제조비와 조립부품 및 조립시간이 증대하는 등의 문제점이 발생되었다.Further, as shown in (b) of FIG. 2, the synthetic resin is molded on the upper side of the iron plate lid and the outer side of the side edge, and the bottom side is molded so that the iron plate is exposed, and then the composite resin plate manufactured separately is assembled on the bottom side of the exposed iron plate lid. Although it is firm and damaged, it is possible to separate the steel plate and the synthetic resin and recycle them as raw materials.However, the synthetic resin board formed separately on the exposed iron plate should be mounted using adhesives and assembly bolts. It must be separately manufactured separately, and the assembly time and assembly time, such as adhesive or assembly bolts are required, the production cost, assembly parts and assembly time is increased.

본 발명은 상기와 같은 문제점을 해소하기 위해, 사출 성형시 매입시키는 금속재 뚜껑을, 놋물이 발생하지 않도록 도금형성시킨 도금판으로 금속재 뚜껑을 형성하여, 저면측이 금속재로 노출되어도, 놋물이 생기지 않으며, 동계절에 신출률이 변화해도 합성수지재와 금속재 뚜껑이 이격되거나 파손되지 않으며, 원재료 대로 분리되어 재활용이 가능하도록 한, 놋물이 생기지 않는 수도미터기 보호통용 보강 뚜껑을 제공하는데 본 발명의 목적이 있는 것이다.In order to solve the above problems, the metal cap to be embedded during injection molding is formed with a plated plate plated to prevent the occurrence of brass, and even if the bottom side is exposed to the metal, the brass does not occur. In order to provide a reinforcing cap for water meter protection casing that does not produce brass, the resin and metal lids are not spaced apart or damaged even when the rate of change is changed in the winter season. will be.

이러한 본 발명 보강 뚜껑(1)을 제조 공정에 의해 설명하면 다음과 같다.When explaining the present invention reinforcing cap (1) by the manufacturing process as follows.

도3과 같이, 합성수지재에 매입시키는 금속재 철판(20)에는 니켈, 크롬, 아 연 도금 등을 형성시켜, 놋이 슬지 않는 갈바륨, 스텐레스 등과 같은 도금판(6)을 형성하고, 녹이 슬지 않는 도금판(6)으로 금속재인 도금 뚜껑(2)을 형성하고, 도금 뚜껑(2)의 상면측과 측면 테두리(3)측에 다수개의 통과공(18)(18') 및 통과공(22)(22')를 형성시킨다.3, nickel, chromium, zinc plating, or the like is formed on the metal sheet 20 to be embedded in the synthetic resin material, thereby forming a plating plate 6 such as galvalume, stainless, which is not brass, and plating which is not rusted. The plate 6 is formed of a plated lid 2 which is a metal material, and a plurality of through holes 18, 18 'and through holes 22 are formed on the upper surface side and the side edge 3 side of the plated lid 2, respectively. 22 ').

도금 뚜껑(2)을 장착시키는 하부금형(13)에는 도금 뚜껑(2)의 통과공(18)(18')과 일치하는 저면측에 다수개의 반환요홈부(19)(19')를 형성하고, 사출 성형하면 도금 뚜껑(2)의 저면측에는 다수개의 걸림환두부(7)(7')가 형성되고, 도금 뚜껑(2)의 테두리(3) 내부측과 저면측에 합성수지 내부 테두리(12)가 형성되도록 하부 금형(13)을 형성하고, 상부 금형(14)에는 도금 뚜껑(2)의 상면측에 일정 두께의 합성수지가 덮혀 상면측 합성수지판(21)이 형성되고, 도금 뚜껑(2)의 테두리(3)외부측에는 합성수지 외부 테두리(10)가 형성되도록 상부 금형(14)을 형성한다.In the lower mold 13 to which the plating lid 2 is mounted, a plurality of return grooves 19 and 19 'are formed on the bottom side of the plating lid 2 which is coincident with the through holes 18 and 18'. When injection molding, a plurality of hook ring heads 7 and 7 'are formed on the bottom side of the plating lid 2, and the inner edge of the resin 12 is formed on the inner side and the bottom side of the edge 3 of the plating lid 2. The lower mold 13 is formed so that the upper mold 14 is formed, and the upper mold 14 is covered with a synthetic resin having a predetermined thickness on the upper surface side of the plating lid 2 to form an upper surface synthetic resin plate 21, The upper mold 14 is formed on the outer side of the edge 3 so that the synthetic resin outer edge 10 is formed.

사출기(15)에 상기와 같이 형성시킨 상부 금형(14)과 하부 금형(13) 및 상, 하부금형(14)(13) 사이에 도금 뚜껑(2)을 장착시켜 사출성형하면, 도금 뚜껑(2)의 상면측과 도금 뚜껑(2)의 테두리(3) 내외부측을 감싸는 형태로 합성수지가 성형되고, 상면측과 내,외부 테두리(12)(10)를 제외한 도금 뚜껑(2)의 저면측 즉, 녹이 슬지 않도록 도금시킨 도금 뚜껑(2)의 저면측 도금판(6)이 노출되고, 하부금형(13)에 형성시킨 반환요홈부(19)(19')에 의해 도금 뚜껑(2)의 통과공(18)(18') 밑에는 걸림환두부(7)(7')가 형성된다.When injection molding is carried out by mounting the plating cap 2 between the upper mold 14 and the lower mold 13 and the upper and lower molds 14 and 13 formed in the injection molding machine 15 as described above, the plating lid 2 The synthetic resin is molded in such a manner as to surround the upper surface side and the inner and outer sides of the edge 3 of the plating lid 2, and that is the bottom side of the plating lid 2 except for the upper side and the inner and outer edges 12 and 10. The bottom plate side plate 6 of the plated lid 2 plated to prevent rust is exposed, and the plated plate 2 passes through the return grooves 19 and 19 'formed in the lower mold 13. Under the balls 18 and 18 ', hook ring heads 7 and 7' are formed.

따라서, 도금 뚜껑(2)의 상면측 합성수지판(21)과 상기 도금 뚜껑(2)의 저면 측 걸림환두부(7)(7')는 사출성형시 통과공(18)(18')에 의해 합성수지로 연결되면서 일체로 형성되게 된다.Therefore, the upper surface side synthetic resin plate 21 of the plating lid 2 and the bottom side locking ring 7, 7 'of the plating lid 2 are formed by the through holes 18 and 18' during injection molding. It is connected to the synthetic resin is formed integrally.

또한, 합성수지 내,외부테두리(12)(10)는 도금 뚜껑(2)의 테두리(3)에 형성시킨 통과공(22)(22')으로 사출성형시 합성수지가 통과하여 연결되면서 일체로 형성되어, 합성수지재인 상면측 합성수지판(21)과 측면측 내외부 테두리(12)(10)와 도금 뚜껑(2)의 저면측 걸림환두부(7)(7')가 일체로 연결되게 형성되어, 성형시킨 합성수지재나 금속재인 도금 뚜껑(2)이 동계절의 신축률 변화에도 이격되거나 파손되지 않게 되고, 녹물이 생기지 않도록 한 수도미터기 보호통용 보강 뚜껑이다.In addition, the inner and outer edges 12 and 10 of the synthetic resin are integrally formed as the through-holes 22 and 22 'formed on the rim 3 of the plating lid 2 are connected while the synthetic resin passes through the injection molding. The upper surface synthetic resin plate 21, the side inner and outer edges 12 and 10, and the bottom side locking ring heads 7 and 7 'of the plating lid 2 are formed to be integrally connected to each other, and then molded. Plating cap (2) made of synthetic resin or metal is a reinforcement cap for water meter protection barrels, which is not spaced apart or damaged even in the change of expansion rate in the winter season and prevents rust.

이와 같이 구성된 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

본 발명의 보강카버(1)는 합성수지에 매입시키는 금속재인 도금 뚜껑(2)를 녹이 슬지 않도록, 도금시킨 도금판(6)을 사용하므로서 사출성형시킨 후에 노출되는 저면측이 녹이 슬지 않게 되므로, 장기간 사용시에도 녹물이 생기지 않게 되어 환경을 오염시키지 않게 된다.The reinforcement cover 1 of the present invention uses the plated plated plate 6 to prevent rusting of the plated lid 2, which is a metal material embedded in the synthetic resin, so that the bottom surface exposed after injection molding does not rust. No rust occurs even when used, so as not to pollute the environment.

또한, 일반 철판과 합성수지를 사출성형시킬 때는 일반 철판과 합성수지의 수축상태가 다르므로, 균열을 방지하기 위해 많은 구멍을 형성시키는데, 이때 형성시킨 많은 구멍을 통해서도 습기가 차서 놋물이 생기나, 본 발명 보강커버(1)는 도금 뚜껑(2)에 형성시킨 다수개의 통과공(18)(18')에는 사출성형시 상면측 합성수지판(21)의 성형과 함께 통과공(18)(18')에도 합성수지가 꽉차게 매입되면서 습기가 올라오는 통과공(18)(18') 밑에는 통과공(18)(18')을 막으면서 넓게 밀착되는 걸림환두부(7)(7')가 형성되어 있으므로, 걸림환두부(7)(7')가 도금 뚜껑(2)의 상면측 에 형성시킨 상면측 합성수지판(21)과 일체로 연결되면서 성형되므로, 상면측 합성수지판(21)과 도금 뚜껑(2)의 이격을 방지 하면서 습기를 차단게하게 되어, 도금 뚜껑(2)에 형성시킨 통과공(18)(18')에 의해서 녹물이 생기지 않게 된다.In addition, when injection molding a general steel sheet and a synthetic resin, the shrinkage state of the general steel sheet and the synthetic resin is different, so that many holes are formed to prevent cracking. The cover 1 has a plurality of through holes 18 and 18 'formed in the plated lid 2, and together with the molding of the upper synthetic resin plate 21 during injection molding, the through holes 18 and 18' are also made of synthetic resin. Under the through-holes 18, 18 'where the moisture is raised while the air is completely filled, the locking ring heads 7, 7' are formed in close contact with each other while blocking the through-holes 18, 18 '. Since the hook ring heads 7 and 7 'are integrally formed with the upper synthetic resin plate 21 formed on the upper surface of the plating cap 2, the upper and lower synthetic resin plates 21 and the plating cap 2 are formed. Moisture is blocked while preventing the separation, and the through holes (18) (18 ') formed in the plating lid (2) This will prevent rust.

또한, 본 발명 보강 뚜껑(1)은 금속재인 도금 뚜껑(2)전체를 매입시켜 합성수지재로 성형시키지 않고 저면측을 노출시켰으며, 도금 뚜껑(2)의 상면측 합성수지판(21)은 도금 뚜껑(2)의 통과공(18)(18')에 의해 걸림환두부(7)(7')에 의해 연결되었고, 도금 뚜껑(2)의 테두리(3) 내외부측에 형성되는 합성수지 내,외부테두리(12)(10)는 도금 뚜껑(2)의 측면측 연결공(22)(22')을 통해 연결 결합되어 있으므로, 신축 공간이 형성되어, 합성수지재와 금속재의 신축율 변화에 대응할수 있게 되고, 이격되거나 파손되지 않게 된다.In addition, the reinforcing lid 1 of the present invention was exposed to the bottom surface without embedding the entire metal plating cap (2) made of a synthetic resin material, the upper surface of the synthetic resin plate 21 of the plating lid 2 is a plating lid The inner and outer edges of the synthetic resin formed on the inner and outer sides of the rim 3 of the plating lid 2 are connected by the hook ring heads 7 and 7 'by the through holes 18 and 18' of (2). Since 12 and 10 are connected to each other through the side connection holes 22 and 22 'of the plating lid 2, an expansion space is formed to cope with changes in the expansion ratio of the synthetic resin material and the metal material. It will not be spaced apart or broken.

또한, 장기간 사용으로 파손되거나, 폐기시에는 도금 뚜껑(2)의 저면측에 형성되어 있는 걸림환두부(7)(7')를 그라인더 등으로 갈아내고, 도금 뚜껑(2)의 테두리(3)밑에 형성되어 있는 내,외부테두리(12)(10)를 감싸고 있는 저면측을 갈아내면 합성수지와 금속재인 도금 뚜껑(2)이 원재료 대로 분리되므로 재활용할 수 있게 된다.In addition, when it is damaged by long-term use or discarded, the locking ring heads 7 and 7 'formed on the bottom side of the plating lid 2 are ground with a grinder or the like, and the edge 3 of the plating lid 2 is removed. When the bottom surface surrounding the inner and outer edges 12 and 10 formed below is ground, the plating lid 2, which is a synthetic resin and a metal material, is separated according to the raw material, and thus can be recycled.

이상에서 상술한 바와 같이, 본 발명은 녹이 슬지 않은 도금판을 이용하여, 도금 뚜껑을 형성하고, 합성수지내에 전체를 매입시키지 않고 저면측을 노출시키므로, 가볍고 견고하며, 동계절에도 이격되거나 파손되지 않고, 놋물이 생기지 않으며, 재활용이 가능하므로 환경을 오염시키지 않는 것이다,As described above, the present invention uses a plating plate that is not rusted to form a plating lid and exposes the bottom side without embedding the whole in a synthetic resin, so it is light and robust, and is not spaced or damaged even in winter season. It does not pollute the environment because it does not produce brass, and is recyclable.
