Handle connecting rod for door lock {Doorknob connecting rod for door lock}

본 고안은 도어로크의 손잡이연결봉에 관한것으로 보다 구체적으로는 도어로크의손잡이와 결합되는 연결봉을 스틸재질의 설치결합대와 삽입관및 고정링과 황동재질의 연결관으로 파트별 제작조립케 구성하므로 연결봉의 제작결합을 용이하고 신속하게 실시할뿐 아니라 강도를 높여 장기간사용가능케 함과 동시에 제작원가를 절감하는데 그 목적이 있는 것이다.The present invention relates to a handle connecting rod of the door lock. More specifically, the connecting rod coupled with the handle of the door lock is manufactured and assembled by part, using a steel mounting coupling rod, an insertion tube, and a fixing ring and a brass connecting tube. The purpose is not only to easily and quickly manufacture and combine the connecting rods, but also to increase the strength of the connecting rods for long-term use and to reduce manufacturing costs.

종래에 도어로크의 손잡이에 결합되는 연결봉은 그 일측으로 결합단부가 구비된 돌출결합부를 형성하고 외주면에는 내협외광되는 경사면과 타측부에 오링홈이 형성되게 구성한것으로 이를 제작시 일체로 주조한 후 연결봉 중심부를 깎아서 천공하는 작업으로 통공과 절개부를 형성하여 연결봉을 제작하므로서 형상사출비용이 비싸며 또 황동으로 제작되어 강도가 약하여 파손우려가 높을 뿐 아니라 제작시 일부분 불량으로 인한 연결봉전체를 폐기하여야 하는 문제점이 있었다.Conventionally, the connecting rod coupled to the handle of the door lock forms a protruding coupling portion having a coupling end portion at one side thereof, and an outer ring is formed with an inclined surface that is externally narrowed and an O-ring groove is formed at the other side. By cutting through the center and forming the through-holes and incisions to make the connecting rods, the cost of injection molding is expensive, and it is made of brass, and the strength is weak. there was.

본 고안은 상기와 같은 종래의 문제점을 보완하고져 안출된 것으로 도어로크의 손잡이와 결합되는 연결봉을 스틸재질의 설치결합대와 삽입관및 고정링과 황동재질의 연결관으로 분해 조립 가능케 구성하여 신속한 제작조립을 실시함과 동시에 강도를 향상시키고 제작비용을 절감하도록 한 것으로 이를 첨부된 도면에 의거 더욱더 상세히 설명하면 다음과 같다.The present invention is designed to supplement the conventional problems as described above, and can be quickly manufactured by disassembling and assembling the connecting rod coupled with the handle of the door lock into the mounting coupling rod and the insertion tube and the fixing ring and the brass connection tube of steel material. Simultaneously with the assembly to improve the strength and to reduce the manufacturing cost as described in more detail based on the accompanying drawings as follows.

본 고안은 도오로크용 손잡이를 손잡이대(101)와 연결봉(1)으로나눠 각기 일체형으로 구성하여 연결봉(1)은 중앙에 통공(1a)이 형성되고 일측단에 돌출결합부 (1c)가 마련되어 그 외주면에 손잡이대(101)의 결합공(102) 내주면의 고정키(103)와 대등하게 걸림단부(1b)(1b')가 양측으로 형성되고 설치결합부(1') 전후방 중심부로는 절개부(11)(12)를 형성하여 설치결합부(1')가 반분되게 하되 그 외주면으로 내협외광의 경사면을 형성하여 된 황동재질의 일체형 연결봉(1)에 있어서The present invention divides the handle for the door lock into a handle bar 101 and the connecting rod (1), each composed of an integrated rod connecting rod (1) is formed in the center through-hole (1a) is provided with a protruding coupling portion (1c) at one end On the outer circumferential surface, the locking end portions 1b and 1b 'are formed on both sides of the coupling hole 102 and the fixing key 103 on the inner circumferential surface thereof. In the integrated connecting rod (1) made of brass, which forms the inclined surface of the inner narrow external light to the outer circumferential surface by forming the portion (11) (12) so that the installation coupling portion (1 ') is half

상기 연결봉(1)을 그 전후방부의 절개부(11)(12) 중앙부에 일정폭 걸림턱 (14)을 형성하고 후방내외측부로 일측에 절개부(2')를 가지고 타측으로는 결합돌기 (2a)(2b)가 돌출형성된 삽입관(2)과 내측상`하부로 결합돌기(3')(31)가 구비된 고정링(3)을 차례로 끼워 설치결합부(1')의 절개부(12)로 삽입관(2)과 고정링(3)의 걸림돌기를 삽입하여 걸림턱(14)에 고정설치되게 하고 설치결합부(1') 외주로는 내협외광으로된 연결관(4)을 씌워 된 것으로 스틸재질의 설치결합부(1')와 삽입관(2)및 고정링(3)과 황동재질의 연결관(4)을 상호 분해 조립가능케 구성한 것이다.The connecting rod 1 has a predetermined width engaging jaw 14 at the center of the cutout portions 11 and 12 at the front and rear portions thereof, and has a cutout portion 2 'at one side to the rear inner and outer portions and a coupling protrusion 2a at the other side. 2b is inserted into the insertion tube (2) protruding and the incision part 12 of the mounting coupling portion (1 ') by inserting the fixing ring (3) with coupling protrusions (3', 31) in the upper and lower 'inner side in turn Insert the locking projections of the insertion tube (2) and the fixing ring (3) to be fixed to the locking jaw (14), and the outer circumference of the installation coupling portion (1 ') is covered with a connecting tube (4) of the inner narrow light The installation coupling portion (1 ') and the insertion pipe (2) and the fixing ring (3) and the connection pipe (4) of brass material made of steel material is configured to be mutually disassembled.

이와 같이 본 고안은 손잡이대(101)와 결합되는 연결봉(1)을 분해조립 가능케 구성하므로서 종래와 같이 주조에 의한 제작 및 가공과 천공작업을 통해 일체형의 구성이 아니라 파트별로 나누어 제작하여 조립결합하므로 제작시간이 단축되고 대량생산이 가능한 이점이 있을뿐 아니라 부분파손시 교체가 편리하며 또 종래에 황동의 재질을 사용하던 것을 본 고안은 설치결합부(1')와 삽입관(2)및 고정링(3)을 스틸재질로 구성하고 설치결합대(1') 외주에 씌워지는 연결관(4)을 황동으로 제작하여 강도를 향상시켜 파손을 예방함과 동시에 제작원가를 절감하여 소비자에게 보다 낮은 가격에 향상된 제품을 공급할 수 있는 이점등을 가지고 있는것이다.As such, the present invention is configured to disassemble and assemble the connecting rod (1) coupled with the handle (101), and thus, by assembling and assembling by dividing the parts by parts instead of the integral structure through the manufacturing and processing and drilling by casting. In addition to the advantages that the production time is shortened and mass production is not only convenient, it is easy to replace at the time of partial breakage, and the present design used a conventional brass material. The installation coupling part (1 ') and the insertion pipe (2) and the retaining ring (3) is made of steel and the connecting pipe (4 '), which is covered on the outer periphery of the mounting coupling (1'), is made of brass to improve the strength to prevent breakage and at the same time reduce the production cost to consumers. It has the advantage of being able to supply improved products.
