Description

다용도 실험용 스탠드 {Multiple experiment stand}Multi-purpose experiment stand {Multiple experiment stand}

본 발명은 다용도 실험용 스탠드에 관한 것으로서, 더욱 상세하게는 실험기구들의 위치조절이 자유로워 안전하고 정확한 실험을 수행하고, 하나의 지지대에 다수의 실험기구를 설치할 수 있으므로 각각의 실험기구에서 서로 다른 실험을 동시에 수행할 수 있는 다용도 실험용 스탠드에 관한 것이다.The present invention relates to a multi-purpose experimental stand, and more specifically, to freely adjust the position of the test apparatus to perform a safe and accurate experiment, and to install a plurality of test apparatus on one support, different experiments in each test apparatus It relates to a multi-purpose experimental stand that can be performed at the same time.

종래의 실험기구들은 용액 및 물질 실험을 행함에 있어 각각의 실험 준비 및 실험기구를 설치함으로써 준비시간 및 실험기구가 많이 소요되어 실제 실험작업이 번거러울 뿐만 아니라 실험에 쓰이는 용액 및 물질들의 낭비가 심한 문제점이 있었다.Conventional test equipments require a lot of preparation time and test equipment by setting up each test preparation and test equipment in conducting a solution and a material test, and the actual experiment work is cumbersome, and waste of solution and materials used in the experiment is severe. There was a problem.

또한, 종래의 국내실용신안 공개번호 제 97-8251 호로 알려진 바 있는 가열기구를 고정하는 실험용 스탠드는 지지대의 수직 절결홈에 따라 상하이동이 가능하여 화학 실험시에 비이커를 알콜램프로 가열하면서 비이커를 받침대의 수평을 유지하면서 높이 조절을 가능하게 하였으나, 다양한 종류의 실험을 행하는 데 있어서는 여전히 큰 불편함이 상존하였는 바, 그 수직위치를 고정하는데 있어서 수직 절결홈으로부터 수평으로 형성된 다수의 수평홈에 의해서만 높이를 조절할 수 있는 제약을 받게 되는 점과, 따로 수평위치의 위치를 고정하는 방법이 없는 점과, 단순히 가열 기구만을 고정할 수 있어 그외 다른 실험은 행할수 없는 점과, 또한 상기 고안의 형상을 제조하는 데 있어 제조단가가 많이 소요되는 문제점이 있었다.In addition, the experimental stand for fixing the heating mechanism, known as the conventional Korean Utility Model Publication No. 97-8251, can be moved to Shanghai according to the vertical notch groove of the support, so that the beaker is heated with an alcohol lamp during the chemical experiment. The height adjustment was possible while maintaining the horizontal level, but there were still great inconveniences in performing various kinds of experiments. Therefore, in order to fix the vertical position, the height was only increased by a plurality of horizontal grooves formed horizontally from the vertical cutout grooves. It is subject to the constraint that can be controlled, there is no way to fix the position of the horizontal position separately, it is possible to simply fix only the heating mechanism can not perform other experiments, and also to manufacture the shape of the design There was a problem that takes a lot of manufacturing cost.

따라서, 본 발명은 전술한 바와 같이 종래 기술의 문제점을 해소하기 위하여 안출한 것으로, 화학 실험시 하나의 지지대에 다수의 실험기구 고정대를 설치하여 실험기구 고정대를 수직이동 및 회전이 가능하도록 하여 각각의 실험기구 고정대에서 서로 다른 실험을 동시에 행할 수 있어 시간과 물자를 절약할 수 있을 뿐만 아니라, 실험 준비 작업이 편리한 다용도 실험용 스탠드를 제공하는데 그 목적이 있다.Therefore, the present invention has been made in order to solve the problems of the prior art as described above, by installing a plurality of test fixtures on one support during the chemical experiment to enable the vertical movement and rotation of the test fixtures, respectively The purpose of the present invention is to provide a versatile test stand that can perform different experiments at the same time in the test fixture holder, saving time and materials, and making the test preparation work convenient.

이러한 목적을 달성하기 위한 본 발명은, 지지대에 상하 수직이동 및 회전이 자유로운 위치 조정부재를 다수 설치한 후 각각의 위치 조정부재에 다수의 실험기구 고정대를 장착하여 각각의 실험기구 고정대의 상하 수직위치와 회전 위치를 자유롭게 조절 및 고정함으로써 달성하였다.In order to achieve the above object, the present invention is provided with a plurality of vertical positioning and rotation free positioning members on the support, and then mounting a plurality of experimental apparatus fixed to each position adjusting member, the vertical vertical position of each experimental instrument holder And freely adjusting and fixing the rotational position.
