본 고안은 익차형 수도미터의 외통체 상부에 나사 결합되어지는 상부캡을 임의로 열지 못하도록 하기 위한 상부캡 임의회전방지장치에 관한 것이다.The present invention relates to an upper cap random rotation preventing device for preventing the arbitrary opening of the upper cap to be screwed on the upper body of the vane water meter.
익차형 수도미터는 통상적으로 제4도에서 보는 바와 같이 계기장치가 수장되어진 외통체 (1) 상부에 나사결합되는 상부캡 (2)의 외면에 형성되어 있는 돌출부 (2a)와 외통체 (1)의 입수구 (1a) 상측에 형성시킨 돌출편 (14)간을 철선이나 구리선등의 연결선 (13)으로 상호 결속하여 상부캡 (2)을 임의로 열지 못하게 하고 연결선 (13)을 납봉 (15)으로 봉인하여 그 결속상태를 풀지 못하도록 하므로서 계기상태를 임의로 조작하지 못하게 하였던 것이다. 그러나 이와 같은 납봉 (15)에 의한 봉인구조는 그 봉인상태가 완벽하지 목하여 조금만 노력하면 연결선 (13)의 결속을 쉽게 해체시킬 수가 있는 것이므로 계기상태의 조작을 보다 완벽하게 방지할수는 없었던 것이다.The vane type water meter is a projection (2a) and the outer cylinder (1) formed on the outer surface of the upper cap (2), which is screwed to the upper portion of the outer cylinder (1) in which the instrument is usually mounted, as shown in FIG. Between the protruding pieces 14 formed on the inlet 1a of the upper portion of the inlet 1a, and the connecting caps 13, such as iron wires or copper wires, are mutually bound so that the upper cap 2 cannot be opened arbitrarily, and the connecting wires 13 are sealed with the lead bar 15. By preventing the unity state from loosening, the instrument state could not be manipulated arbitrarily. However, such a sealing structure by the lead bar 15 is not perfect, the sealing state can not easily prevent the operation of the instrument state because it is easy to dismantle the binding of the connecting line 13 with a little effort.
본 고안은 이와 같은 종래의 문제점을 해결하여 수도미터의 계기상태조작을 완벽하게 방지토록 함에 그 목적이 있는 것으로, 첨부 도면에 의거 상세히 설명하면 다음과 같다.The present invention has the purpose to completely prevent the operation of the instrument state of the water meter by solving such a conventional problem, will be described in detail based on the accompanying drawings.
즉, 통상의 익차형 수도미터 외통체 (1)의 상부에 나사 결합되는 상부캡 (2)의 회전을 방지하여 이를 임의로 열지 못하도록 하는 상부캡 임의회전방지장치의 외통체 (1)의 입수구 (1a) 상측에 설치되는 통상적인 기차조절장치의 볼트머리 (3) 상단에 경사면을 가진 걸림턱 (4)을 형성한 것에 있어서 (3)가 끼워지는 삽입공 (5)의 외주연에다 절결부 (6a)에 의해 다수개로 분할되며 상향 경사지게 한 탄성걸림편 (6)을 형성하여 볼트머리 (3)의 상단 걸림턱 (4)에 끼워져 걸리도록 하고, 호형으로 만곡 요입되어진 선단면 (7)은 상부캡 (2)의 외면에 밀접되도록 한 합성수지제 회전방지구 (8)를 설치하여서 상부캡 (2)의 회전을 방지토록 구성한 익차형 수도미터의 상부캡 임의회전 방지장치인 것이다. 첨부도면중 미설명부호 9는 기차조절구멍, 10은 기차조절장치마개, 11은 기차조절관, 1b는 배수구, 2'는 뚜껑, 12는 외통체 (1) 내부에 설치되는 상부갑체를 나타내는 것이다.That is, the inlet 1a of the outer cylinder 1 of the upper cap random rotation preventing device that prevents rotation of the upper cap 2 screwed to the upper portion of the conventional vane type water meter outer cylinder 1 so as not to open it arbitrarily. (6a) in the outer periphery of the insertion hole (5) into which the (3) is fitted, in which a locking jaw (4) having an inclined surface is formed on the upper end of the bolt head (3) of a conventional train control device installed above. ) Is formed into a plurality of and is inclined upwardly to form an elastic engaging piece (6) to be fitted to the upper locking jaw (4) of the bolt head (3), and the end surface (7) curved concave in an arc shape is the upper cap It is a device for preventing random rotation of the upper cap of the vane-type water meter, which is configured to prevent rotation of the upper cap 2 by installing a synthetic resin rotation preventing device 8 close to the outer surface of (2). In the accompanying drawings, reference numeral 9 denotes a train control hole, 10 a train control plug, 11 a train control pipe, 1b a drain, 2 'a lid, and 12 a top body installed inside the outer cylinder 1. .
본 고안의 설치상태를 설명하면 외통체 (1)의 입수구 (1a) 상측에 설치되어 있는 기차조절장치의 볼트머리 (3)에다 합성수지제 회전방지구 (8)의 후방에 형성시킨 삽입공 (5)을 끼워주게 되면, 상기 삽입공 (5)의 외주연에 상향 형성되어 절결부 (6a)에 의해 다수개로 분할되어진 탄성걸림편 (6)들이 볼트머리 (3)의 상단걸림턱 (4) 경사면을 타고 외측으로 벌어지게 되면서 상단 걸림턱 (4) 부위를 벗어났을때 외측으로 벌어졌던 탄성걸림편 (6)들은 다시 자체탄성으로 오므러들게 되면서 이후 걸림턱 (4)에 의해 볼트머리 (3)에서 이탈되지 못하게 되는 것이며, 회전방지구 (8)의 선단면 (7)은 호형으로 만곡 요입되어져 있어서 상부캡 (2)의 외면에 밀접되어지게 되는 것이다. 따라서 계기상태를 임의로 조작하고자 상부캡 (2)을 열어 분해하고 싶어도 상부캡 (2)을 회전시키게 되면 상부캡 (2)의 외면에 돌설되어 있는 기존의 돌출편 (2a)들이 회전방지구 (8)에 걸리게 되므로서 상부캡 (2)외 좌우회전이 불가능하게 되는 것이다. 따라서 상부캡 (2)을 회전시켜 열기 위해서는 회전방지구 (8)의 탄성걸림편 (6)들을 파선시켜야만 되는데 이를 파손시키게 되면 수도미터의 계기상태를 임의로 조작한 비양심적 행위가 쉽게 탄로나기 마련이므로 이와 같은 비양심적 행위를 전혀 시도할 수 없게 되는 것이다.In the installation state of the present invention, an insertion hole formed in the bolt head 3 of the train control device installed above the inlet port 1a of the outer cylinder 1 in the rear of the synthetic resin rotation stopper 8 ), The elastic engaging pieces (6) formed upwardly on the outer circumference of the insertion hole (5) and divided into a plurality by the notch (6a) are inclined surface of the upper locking jaw (4) of the bolt head (3) The elastic catching pieces 6 which were opened outwardly when they escaped from the upper catching jaw (4) while they were spread outwardly were retracted back to their own elasticity, and then the bolt catching (3) by the catching jaw (4). The front end surface 7 of the anti-rotation tool 8 is not curved, and is curved in an arc shape so as to be in close contact with the outer surface of the upper cap 2. Therefore, even if you want to open the upper cap (2) to disassemble the instrument state arbitrarily, if the upper cap (2) is rotated, the existing protrusions (2a) protruding on the outer surface of the upper cap (2) is an anti-rotation opening (8) ), So that the left and right rotation outside the upper cap (2) is impossible. Therefore, in order to rotate and open the upper cap (2), it is necessary to break the elastic catching pieces (6) of the anti-rotation tool (8). If this is broken, the unscrupulous action that arbitrarily manipulates the meter state of the water meter is easily traversed. You will not be able to try the same unscrupulous behavior at all.
본 고안은 상술한 바와 같이 회전방지구 (8)를 기차조절장치의 볼트머리 (3) 상단에 형성시킨 걸림턱 (4)에 끼워 걸리도록 하는 간단한 구조로서 수도미터기 외통체 (1)의 상부캡 (2)을 임의로 열지 못하게 하여 계기상태의 조작우려를 완벽하게 해소시켜주므로서 정확한 수도사용량을 계측할 수 있게 되는 매우 실용적인 효과를 제공하여주는 것이다.The present invention is a simple structure to be fitted to the locking projection (8) formed on the top of the bolt head (3) of the train control device as described above, the upper cap of the water meter outer cylinder (1) It does not open (2) arbitrarily and completely eliminates the concern about the operation of the instrument, thus providing a very practical effect that can measure the exact water consumption.
