도어록용 래치볼트{DOOR ROCK LATCH BOLT}Latch Bolt for Door Lock {DOOR ROCK LATCH BOLT}

본 고안은 도어록용 래치볼트의 재료비 절감 및 스프링 결착구조 개선방법에 관한 것으로 특히 래치볼트의 제작방법을 철판을 이용한 금형프레싱기법에 의하여 몸체부와 헤드부 및 헤드덮개를 제작결합하여 헤드부 내부에 공간부를 형성시켜 주고 헤드덮게 결합지지부에 스프링 결착돌출돌기를 구비하여 래치볼트의 좌, 우 탄성스프링 작동의 원활을 기하며 재료비절감을 가져올 수 있는 방식의 도어록용 래치볼트의 헤드덮개 및 스프링 결착구조 개선방법에 관한 것이다.The present invention relates to a method of reducing the material cost of the latch bolt for the door lock and improving the spring fastening structure. In particular, the manufacturing method of the latch bolt is manufactured by combining the body part, the head part, and the head cover by a die pressing method using an iron plate. The head cover and spring binding structure of the door lock latch bolt for the door lock which forms a space part and has spring binding protrusions on the coupling support head to cover the head, thereby facilitating the operation of the left and right elastic springs of the latch bolt and reducing the material cost. It is about improvement method.

본 고안은 종래의 방식들이 래치볼트의 헤드부를 제작함에 있어서 철판 및 스텐을 재료로 하여 헤드부의 내부에 공간부를 형성시켜 재료비 절감에만 치중한 결과, 정작 래치볼트의 핵심기능을 담당하는 스프링의 헤드부와 결착연결 및 작동문제와 헤드덮개의 유동 및 이탈문제에 관하여는 제 기능적 안출이 되지 못함으로 인하여 헤드부 후면과 밀림 지지되는 스프링이 비트러지는 등의 문제점으로 스프링의 탄성밀림 및 수축기능에 의한 래치볼트의 좌, 우 작동불량으로 도어록 어셈블리의 제 기능이 십분 발휘되지 못하는 문제점 및 헤드덮개의 유동 및 이탈을 개선하기 위한 도어록용 래치볼트의 헤드덮개 및 스프링 결착구조 개선방법에 관한 것이다.The present invention is to produce the head portion of the latch bolt in the conventional methods to form a space portion inside the head portion of the steel plate and the stainless steel as a result of focusing only on the material cost reduction, the head portion of the spring that is responsible for the core function of the latch bolt And the connection and operation problems of the head cover, and the flow and departure of the head cover, due to the failure of the functional draft, the spring that is supported by the rear of the head and the sliding support, etc. The present invention relates to a method of improving the head cover and spring fastening structure of a latch bolt for a door lock to improve the flow and detachment of the head cover and a problem in which the function of the door lock assembly is not exerted due to the left and right malfunction of the latch bolt.

본 고안은 상기의 문제점을 개선하기 위하여 몸체부 및 헤드부와 헤드덮개로 구성되는 래치볼트의 제조에 있어서 철판 및 스텐을 재료로 하여 몸체부 및 헤드부를 프레스성형방법으로 성형가공함에 있어 몸체부와 헤드부 양 경계지점의 두 측벽부 윗면 선상부에 결착홈을 두 홈 가공하고 몸체부 바닥부에서 사격타겟 형상으로 펀칭된 헤드덮개 결합지지부재를 90°로 헤드부 방향으로 직립시킨 후, 프레스가공된 헤드덮개의 양결착날편을 몸체부 결착홈에 끼움결착함과 동시에 몸체부의 헤드덮개결합지지부재와도 결착고정되게 하여 헤드부에 공간부가 형성되게 하고 헤드덮 개 결합지지부재의 후면중앙부에는 스프링이 압착고정될 수 있도록 스프링결착돌출돌기를 헤드덮개 결합지지부재와 일체로 프레스가공방식으로 구비하여 스프링이 입착고정되었을 때 비트러짐을 방지할 수 있는 방식의 도어록용 래치볼트의 헤드덮개 및 스프링 결착구조 개선방법에 관한 것이다.The present invention in order to improve the above problems in the manufacture of the latch bolt consisting of the body portion and the head portion and the head cover made of iron plate and stainless steel material and the body portion and the head portion in the molding process by the press molding method After two grooves are formed in the upper line of the two side walls of the head part, the binding grooves punched in the shape of the target of shooting at the bottom of the body are erected at 90 ° in the direction of the head part. Both fastening blades of the fixed head cover are fitted into the body binding groove, and at the same time, it is also fixed to the head cover coupling support member of the body so that a space is formed in the head and a spring is formed at the rear center of the head cover coupling support member. The spring-loaded protrusion is integrally provided with the head cover coupling support member so that the spring-loaded protrusion can be pressed and fixed so that the spring can be fixed. Eoteul when the bit head of the cover can be prevented reojim way door lock latch for the spring with the bolt and the binder structure relates to improved methods.

본 고안은 래치볼트를 제조함에 있어서 상기의 개선방법을 적용함으로써 재료비 절감과 함께 스프링이 래치볼트 헤드부의 스프링결착 돌출돌기에 입착고정되므로 특히 스프링의 이탈 및 비트러짐이 방지되므로 래치볼트의 좌, 우 스프링탄성 작동기능이 더욱 개선된 효과를 가져 올 수 있으며 헤드덮개의 유동 및 이탈 또한 방지될 수 있는 도어록용 래치볼트의 헤드덮개 및 스프링 결착구조 개선방법에 관한 것이다.The present invention, in the manufacture of latch bolts, by applying the above improvement method, the spring is fixed to the spring-loaded protrusion projection of the latch bolt head portion, and the spring bolt is fixed to the latch bolt head part is prevented in particular because the spring is prevented from falling off and left and right of the latch bolt The spring-elastic actuation function is to improve the head cover and spring fastening structure of the latch bolt for the door lock that can bring more improved effect and also prevent the head cover flow and detachment.
