An electric shock protecting lock includes a body(1), a hook(2), a key box(3), a cylinder(4), a locking ball(5), and a rotor(6). The body and the rotor are made of a nonconductive material while the hook, the key box, the cylinder, and the locking ball are made of a metal material. The key box is installed inside the body, and the cylinder is installed inside the key box. The locking ball controls appearance of the hook. The rotor is rotated by the locking ball and the cylinder, and receives or pushes out the locking ball.

본 발명은, 산업 설비에 있어서, 콘트롤 박스나 배전반 등의 장치를 잠글 때 사용하는 자물쇠에 관한 것이다.TECHNICAL FIELD This invention relates to the lock used when locking apparatuses, such as a control box and a switchboard, in industrial facilities.

산업 설비에 있어서, 콘트롤 박스나 배전반 등의 문을 잠글 때 사용하는 종래의 자물쇠는, 거기에 감전 방지수단이 구비되어 있지 아니하여 정기 점검을 위한 개문이나 운용을 위한 개문 등의 작업시 감전의 위험이 있었다. 즉, 배전반 등에 누전이 발생한 경우 작업자는 자물쇠를 열기에 큰 어려움이 있는 것이다. 자물쇠 몸체를 부도체로 감싸야 하며, 일반적으로 금속으로 형성된 열쇠 또한 부도체로 감싸서 자물쇠를 열어야 하기 때문이다. 그런데, 위와 같은 콘트롤 박스나 배전반 등의 경우에는 누전의 염려가 크고 잦아 점검이나 수리 작업에 있어 감전으로 인한 작업의 불편이 다대한 결점이 있었다.In industrial facilities, conventional locks used to lock doors such as control boxes and switchboards are not equipped with electric shock prevention means, so that the risk of electric shock during work such as opening for regular inspection or opening for operation is not provided. There was this. That is, when a short circuit occurs in the switchboard, the worker has a great difficulty in opening the lock. This is because the lock body must be wrapped with a non-conductor, and a key made of metal must also be wrapped with a non-conductor to open the lock. However, in the case of the control box or switchboard as described above, there is a large number of shortcomings due to the risk of short circuit, and the inconvenience of working due to electric shock in the inspection or repair work.

자물쇠는 일반적으로, 첨부된 도면에 도시된 바와 같이, 몸체(1)와 몸체(1)에 설치된 걸고리(2)와 몸체(1) 내부에 설치된 키통(3)과 키통(3) 내부에 설치된 실린더(4), 걸고리(2)의 출몰을 제어하는 잠금볼(5) 및 실린더(4)에 의하여 회전되며 잠금볼(5)을 수납하거나 외방으로 밀어내는 회전자(6)로 구성된다.The lock is generally a hook (2) installed in the body (1) and the body (1) and a key barrel (3) installed inside the body (1) and a cylinder installed in the key cylinder (3), as shown in the accompanying drawings. (4), the locking ball (5) for controlling the appearance of the hook (2) and the rotor (4) is rotated by the lock ball (5) to accommodate or push outward.

이러한 자물쇠는 잠금장치 일반에서의 특성상 상당한 정도의 강도를 필요로 하니 이러한 자물쇠를, 감전의 염려를 해소시키기 위한다 해서라도, 그 강도가 충분치 아니하여 잠금의 목적을 달성할 수 없는 합성수지와 같은 부도체로 형성시킬 수는 없는 것이다. These locks require a considerable degree of strength due to the characteristics of the locking device in general, and even if the lock is intended to solve the risk of electric shock, the lock is made of an insulator such as a synthetic resin that is insufficient in strength to achieve the purpose of locking. It cannot be formed.

그런데, 본 발명자는 자물쇠의 특성상 자물쇠를 금속으로 형성시켜야만 한다 하더라도, 적어도 그 몸체만은 이를 금속이 아닌 고강도 합성수지로 형성시키더라도 아무런 문제가 없음을 알았다. 그리하여 본 발명자는 몸체(1)를 합성수지로 형성시킴으로서 자물쇠 몸체를 만지는 것만으로는 감전이 되지 않음을 알게 되었다. 그러나, 아무리 몸체를 부도체로 형성시킨다 하더라도 몸체에 열쇠를 꽂으면 열쇠를 통하여 감전되는 일은 막을 수 없었고, 열쇠로 작동되는 부분은 고강도를 요하니 이들을 합성수지와 같은 부도체로 형성시키는 일은 불가능함을 알았다. However, the present inventors have found that even if the lock has to be formed of a metal due to the nature of the lock, at least the body has no problem even if it is formed of a high strength synthetic resin instead of the metal. Thus, the inventors have found that by touching the lock body by forming the body 1 with synthetic resin, there is no electric shock. However, even if the body was formed of insulator, it could not prevent the electric shock through the key when the key was inserted into the body.

그러던 중, 본 발명자는 자물쇠의 구성부품 중 적어도 회전자(6)만은 단지 잠금볼(5)을 수납하거나 외측으로 밀어내는 작용을 하므로 그 작용에 큰 강도를 필요로 하지 않음을 발견하였다. 이에 본 발명자는 이러한 회전자(6)를 부도체로 형성시킴으로서 걸고리(2)로부터 실린더(4)까지의 전기 회로를 차단함으로서, 결국, 몸체(1)와 이에 끼우는 열쇠에도 누전된 전류가 흐르지 아니하게 함으로서, 배전반 등에 누전 전류가 발생하였다 하더라도 안심하고 자물쇠를 열 수 있도록 하였는 바, 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.In the meantime, the inventors have found that at least the rotor 6 of the components of the lock only acts to receive the lock ball 5 or to push it outward, and therefore does not require great strength for its action. Accordingly, the present inventors block the electric circuit from the hook 2 to the cylinder 4 by forming the rotor 6 as a non-conductor, so that no short-circuit current flows in the body 1 and the key inserted therein. By doing so, even if a leakage current occurs in the switchboard, so that the lock can be opened with confidence, the present invention will be described with reference to the accompanying drawings as follows.

본 발명은 자물쇠 일반이 그러한 바와 같이 몸체(1)와 몸체(1)에 설치된 걸 고리(2)와 몸체(1) 내부에 설치된 키통(3)과 키통(3) 내부에 설치된 실린더(4), 걸고리(2)의 출몰을 제어하는 잠금볼(5) 및 실린더(4)에 의하여 회전되며 잠금볼(5)을 수납하거나 외방으로 밀어내는 회전자(6)로 구성된다.The present invention is a lock (2) and the hook (2) installed on the body (1) and the body (1) and the key cylinder (3) and the cylinder (4) installed inside the key cylinder (3) installed inside the body (1), Rotating by the locking ball (5) and the cylinder (4) for controlling the appearance of the hook (2) and consists of a rotor (6) for receiving or pushing out the locking ball (5).

그런데, 본 발명은 위와 같은 통상의 자물쇠에 있어서, 그 몸체(1)를 부도체로 형성시키는 것으로부터 출발한다. 몸체(1)를 부도체로 형성시키는 일은 장난감 자물쇠 등에서 볼 수 있는 일이기도하다. 그러나, 본 발명은 몸체(1)를 부도체로 형성시킬 뿐, 걸고리(2)는 이를 금속으로 형성시키는 것이어서 위와 같은 장난감자물쇠와는 구별되어야 한다. 뿐만 아니라, 본 발명은 몸체(1)의 내부에 설치하는 키통(3)과 키통(3)의 내부에 설치되는 실린더(4) 및 걸고리(2)의 출몰을 제어하는 잠금볼(5) 또한, 통상의 자물쇠에서 보는 바와 같이, 이들을 금속으로 형성시킨다. 다만, 본 발명은, 실린더(4)에 의하여 회전되며 잠금볼(5)을 수납하거나 외방으로 밀어내는 회전자(6)만은 이를 부도체로 형성시키는 것을 특징으로 하는 것이다.By the way, this invention starts from forming the body 1 by an insulator in the above conventional lock. Forming the body 1 into an insulator is also a thing that can be seen in toy locks and the like. However, the present invention only forms the body 1 with a non-conductor, and the hook 2 is formed with a metal, so it should be distinguished from the toy lock as described above. In addition, the present invention is a key ball (3) installed in the interior of the body (1) and the locking ball (5) for controlling the appearance of the cylinder (4) and the hook (2) is installed inside the key barrel (3), As seen in conventional locks, they are formed of metal. However, the present invention is characterized in that only the rotor 6 which is rotated by the cylinder 4 and accommodates the locking ball 5 or pushes outward is formed as a non-conductor.

이와 같이 구성된 본 발명은, 걸고리(2)라던가 잠금볼(5) 및 키통(3)이나 실린더(4)가 모두 금속으로 형성되어 있어 그 잠금 효과가 통상의 자물쇠에 있어서와 동일하다.In the present invention configured as described above, the hook 2, the locking ball 5, the key barrel 3, and the cylinder 4 are all made of metal, and the locking effect thereof is the same as in a normal lock.

그런데, 콘트롤 박스 등에 누전이 발생하여 그 누전 전류가 걸고리(2)에 까지 도달한다 하더라도, 본 발명의 자물쇠는 그 몸체(1)가 부도체로 형성되어 있으니, 전류가 부도체인 몸체(1)에 전달 되지 아니하고, 또한, 전류가 걸고리(2)를 통 하여 잠금볼(5)에 까지 도달하였다 하더라도 잠금볼(5)과 실린더(4) 사이에는 부도체로 된 회전자(6)가 개재되어 있어 전류를 차단하므로, 누전 전류가 실린더(4)는 물론 이에 끼워 질 열쇠에 까지는 도달하지 아니하게 되어 배전함 등의 자물쇠를 열기에 어려움이 없게 되는 효과가 있다. 특히, 본 발명은 자물쇠의 구성 부품 중 비교적 그 강도가 크지 않아도 좋은 회전자(6)를 비교적 강도가 낮은 부도체로 형성시킴으로서 자물쇠로서의 기능에 장애를 제공하지 않으면서도 감전의 염려가 없이 안심하고 자물쇠의 해정작업을 수행할 수 있게 되는 효과가 있다. By the way, even if a short circuit occurs in a control box or the like and the short circuit current reaches the hook 2, the lock according to the present invention transmits the current to the non-conductive body 1 because the body 1 is formed of a non-conductor. In addition, even if the current reaches the locking ball 5 through the hook 2, a non-conductive rotor 6 is interposed between the locking ball 5 and the cylinder 4, so that the current Since the interruption current does not reach the cylinder 4 as well as the key to be inserted therein, there is an effect that there is no difficulty in opening a lock such as a distribution box. In particular, the present invention forms the rotor 6, which does not have to be relatively strong, among the components of the lock, by forming a non-conductor having a relatively low strength so that the lock can be safely and securely without providing an obstacle to its function. There is an effect to be able to perform the decommissioning work.
