본 고안은 줄자의 인출입을 자동화한 자동권척에 관한 것이다.The present invention relates to an automatic winding that automates the withdrawal of tape measure.
종래의 권척은 줄자를 갑체의 내부에 스프링에 의해 권취되도록 설치하여서 된것으로 검척이 끝난후 인출한 줄자를 갑체에 넣을 때는 스프링의 감김작동에 의해 자동으로 권취되어지나 줄자를 인출시킬때는 수동으로 줄자를 빼내어야 하는 번거로움과 불편이 있었다.Conventional winding is made by installing a tape measure inside the body to be wound by the spring. When putting the tape measure drawn out after the inspection, it is automatically wound by the winding action of the spring. There was a hassle and inconvenience to pull out.
본 고안은 이와 같은 점을 감안하여 안출한 것으로 케이스의 내부에 줄자 권취롤과 안내롤을 일정간격으로 출설하여 이를 역회전이 가능한 모타에 의해 기어를 매개로 정, 역회전 시키므로서 줄자의 인출입을 자동으로 할수 있게한 것인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been made in view of the above points, and the tape take-up roll and the guide roll are placed inside the case at regular intervals, and the tape can be pulled in and out by rotating the gears by the motor capable of reverse rotation. It is possible to do it automatically, which will be described in detail according to the attached drawings as follows.
케이스(1)의 내부에 줄자(2)가 권취되는 롤(3)과 일정거리를 두고 이송로울러(4)(4')를 상하로 설치하여 롤(3)과 하측 이송로울러(4)에 웜휠(5)(5') 을 각각 축설하되 웜훨(5)(5')은 역회전이 가능한 통상의 D. C.모타(6)의 웜휠(7)과 치합시킨 웜출(8) 양단의 웜기어(9)(9')와 치합시키고 케이스(1)의 내부 일측에는 건전지(10)을 수납하여 도선(11)을 매개로 모타(6)와 접리스위치(12)를 연결하여서 된는 것이다.A worm wheel is installed on the roll 3 and the lower feed roller 4 by installing the feed rollers 4 and 4 'up and down at a predetermined distance from the roll 3 on which the tape measure 2 is wound inside the case 1. (5) (5 '), respectively, but the worm gears (5) and (5') are worm gears (9) at both ends of the worm wheel (8) engaged with a worm wheel (7) of a conventional DC motor (6) capable of reverse rotation. 9 ') and the inner side of the case (1) to accommodate the battery (10) by connecting the motor 6 and the folding switch 12 via the conductor (11).
도면중 미설명부호 13은 뚜껑이고 14는 건전지 수납케이스이다.In the drawings, reference numeral 13 denotes a lid and 14 denotes a battery storage case.
이와 같이된 본 고안은 케이스(1)의 내부에 건전지(10)을 수납한후 스윗치(12)를 접속시켜 모타(6)를 정회전 또는 역회전되게 작동시키면 모타축 축착된 웜휠(7)이 동시에 회전하여 상단에 치합된 웜축(8)을 회전시키게 되고 웜축(8)이 회전되면 이에 치합돈 롤(3)과 이송로울러(4)의 웜휠(5)(5')이 동시에 회전하게 되므로 롤(3)에 권취된 줄자(2)가 이송로울러(4)(4')의 안내를 받아 자동으로 인입 또는 인출되는 것이다.According to the present invention, the battery 10 is stored in the case 1, and then the switch 12 is connected to operate the motor 6 to rotate forward or reverse. The worm shaft 8 rotates at the same time and rotates the worm shaft 8 engaged at the top. When the worm shaft 8 is rotated, the worm wheel 3 and the worm wheels 5 and 5 'of the feed roller 4 rotate simultaneously. Tape measure (2) wound in (3) is automatically withdrawn or withdrawn by the guidance of the transfer roller (4) (4 ').
따라서 스윗치(12)에 모타(6)의 회전방향에 따라 인출입을 표시하여 놓고 검척을 할때 스윗치(12)를 인출로 작동시키면 줄자(2)가 모타(6)의 연동을 받아 회전되는 롤(3)과 이송로울러(4)에 의해 자동으로 케이스(1)밖으로 나오게 되고 검축이 끝난후 스윗치(12)를 인입으로 작동시키면 모타(6)가 역회전을 하여 롤(3)과 이송로울러(4)를 반대로 회전시키게 되므로 인출된 줄자(2)가 케이스(1)의 내부에 자동으로 인입되면서 롤(3)에 권취 되는 것이다.Therefore, when the drawer 12 is displayed according to the rotation direction of the motor 6 on the switch 12 and the switch 12 is operated by the drawer when the inspection is performed, the tape measure 2 is rotated by the interlocking of the motor 6. 3) and the transfer roller (4) automatically comes out of the case (1), and after the end of the inspection when the switch (12) is operated by retracting the motor (6) to reverse the roll (3) and the roller (4) Because it is rotated in reverse), the tape measure 2 drawn out is automatically wound into the inside of the case 1 and wound around the roll 3.
건전지(10)는 케이스(1)의 내부에 설치된 건전지 수납케이스(14)에 수납하여 외부에서 뚜껑(13)으로 개폐되게하면 건전지(10)를 자유롭게 교체할 수 있다.The battery 10 may be freely replaced when the battery 10 is stored in the battery storage case 14 installed inside the case 1 and opened and closed by the lid 13 from the outside.
이와 같이 본 고안은 권척의 줄자(2)를 모타(6)로서 자동 인출입 되게 하므로서 줄자(2)의 사용을 용이하게 하는 효과가 있다.In this way, the present invention has an effect of facilitating the use of the tape measure 2 by allowing the tape measure 2 of the chuck to be automatically drawn in and out as the motor 6.
