Description
본 발명은 속도조절이 가능한 뷰렛에 관한 것으로, 더욱 상세하게는 뷰렛의 하단에 구면 이동하는 조절장치로 관의 가압되는 정도에 따라 용액이 떨어지는 량을 조절할 수 있도록 한 뷰렛을 제공하기 위한 것이다.The present invention relates to a burette capable of speed adjustment, and more particularly, to provide a burette that can adjust the amount of solution falling in accordance with the degree of pressure of the tube with a spherical moving device at the bottom of the burette.
종래의 뷰렛은 제 2도에 도시한 바와 같이 용액이 떨어지는 속도를 조절하는 뷰렛 코크에 구멍이 한 개만 뚫려 있어 코크를 돌리는 정도에 따라 그 구멍이 막혀서 용액이 덜 나오게 하는 것인데, 이는 뷰렛 코크를 살짝 열었다가 다시 잠그는 행동을 반복해야만 용액의 떨어지는 속도 조절이 가능하다.In the conventional burette, as shown in FIG. 2, only one hole is drilled in the burette coke, which controls the rate at which the solution falls, so that the hole is blocked according to the degree of turning the cock. You can control the dripping rate only by opening and closing the lock again.
또한 코크를 어느 정도의 각도로 돌렸을 때 어떤 각도에서 용액이 한 방울씩떨어지는 속도를 쉽게 알 수 없어 실험자들이 애를 먹곤 하였다.Also, when the cock was turned at an angle, the experimenter struggled because it was not easy to know the speed at which the solution dropped drop by angle.
또한 기존의 뷰렛은 손잡이 부분이 작고 뻑뻑하여 초보자들이 실험시 많은 에러를 범하고 하였다.In addition, the existing burette has a small and stiff handle, so that novices make a lot of errors when experimenting.
본 발명은 상기한 바와 같은 문제점을 해소하기 위해 안출된 것으로, 본 발명의 목적은 뷰렛 몸체의 하단에 연질의 테프론 관으로 이루어진 접속관을 결합하여 상기 접속관에 구면 이동하면서 압압에 의하여 테프론 관을 가압하는 조절장치를 형성하여 관의 가압되는 정도에 따라 용액이 떨어지는 량을 조절할 수 있도록 구성한 것이다.The present invention has been made to solve the above problems, an object of the present invention is to combine the connection tube made of a soft Teflon tube to the lower end of the burette body spherical to the connection tube while pressing the teflon tube by pressing Forming a pressure adjusting device is configured to control the amount of solution falling according to the degree of pressure of the tube.

이하 첨부된 도면을 참조하면서 본 발명에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 뷰렛을 나타낸 도 1을 참조하면, 코크를 돌리는 정도에 따라 그 구멍이 막혀서 용액 조절을 하는 공지의 뷰렛에 있어서, 뷰렛 몸체(2)의 하단에 연질의 테프론 관으로 이루어진 접속관(4)을 결합하고, 상기 접속관(4)에 구면 이동하면서 압압에 의하여 테프론 관을 가압하는 조절장치(20)를 형성하여 관의 가압되는 정도에 따라 용액이 떨어지는 량을 조절할 수 있도록 구성한 것이다.Referring to Fig. 1 showing a burette according to the present invention, in the known burette to block the hole according to the degree of turning the cock to adjust the solution, the connection tube made of a soft Teflon tube at the bottom of the burette body (2) 4) is coupled to the spherical movement to the connecting pipe (4) to form a regulator 20 for pressing the Teflon tube by pressing is configured to adjust the amount of the solution falling depending on the degree of pressure of the tube.
이때 뷰렛 몸체(2)에 결합된 접속관(4)의 하단은 튜브체(22)로 구성하여 구면 이동하는 조절장치(20)로 손쉽게 가압이 가능하도록 하며 튜브체(22)의 휘어짐을 방지하기 위하여 조절장치(20)와 튜브체(22)를 플라스틱 고정봉(24)으로 결합구성한다.At this time, the lower end of the connecting tube 4 coupled to the burette body 2 is composed of a tube body 22 so as to be easily pressurized by the spherical control device 20 and to prevent the bending of the tube body 22. In order to combine the adjusting device 20 and the tube body 22 with a plastic fixing rod (24).
이때 조절장치(20)는 함체형으로 구성되면서 바닥면에 경사면이 형성되고, 주연부로는 로울러(30)가 형성되어 튜브체(22)를 타고 로울러(30)가 구면 운동하도록 한다.At this time, the adjusting device 20 is formed in a box shape, the inclined surface is formed on the bottom surface, the roller 30 is formed in the peripheral portion so that the roller 30 is spherical movement on the tube body 22.
또한 고정봉(24)은 조절장치(20)에 일체로 형성하거나 접착제로 고정하면서 튜브체(22)를 고정하면 되는 것이고, 타이밴드 등 딱딱한 재질로 튜브체(22)가 휘어짐이 발생되지 않을 정도로 고정하면 가능한 것이다.In addition, the fixing rod 24 is to be formed integrally to the adjusting device 20 or to fix the tube body 22 while fixing with an adhesive, so that the tube body 22 is not bent with a hard material such as tie bands It is possible to fix it.
상기와 같이 이루어진 본 발명은 뷰렛 몸체(2)에 저장된 용액을 떨어지도록 할 때 조절장치(20)에 결합된 로울러(30)를 구면 이동시키면 로울러(30)의 이동에 따라 경사면에 의하여 튜브체(22)를 압압하여 조절함으로서 용액량을 조절할 수 있는 것이다.According to the present invention made as described above, when the roller 30 coupled to the adjusting device 20 is spherically moved to drop the solution stored in the burette body 2, the tube body is inclined according to the movement of the roller 30. 22) by pressing to adjust the amount of solution can be controlled.
상술한 바와 같은 본 발명은 로울러의 이동에 의하여 원하는 량으로 용액이 떨어지는지를 알 수 있어 속도조절이 가능하도록 한 뷰렛을 제공할 수 있는 것이다.As described above, the present invention can provide a burette capable of adjusting the speed by knowing whether the solution falls to a desired amount by moving the roller.
