Abstract
The utility model relates to a graduated flask support for chemistry experiments, including supporting baseplate, the graduated flask that is the rectangle structure, supporting baseplate upper end middle part is equipped with the vertical guide bar of arranging, be equipped with on the guide bar and support the cover, be equipped with the backup pad that the level was arranged on support cover one side, be equipped with the vertical dead lever of arranging on backup pad one side, dead lever one side is equipped with the fixing clip, the fixing clip is connected with the graduated flask, it is connected with the vertical regulation pole output of arranging to support the cover. The utility model discloses during the use, placing the graduated flask in the backup pad, then fixing through the fixing clip, will adjust the extension of pole length according to the height of experimenter and make the backup pad to carry out the rebound along the guide bar, the graduated flask is watched to the experimenter level of being convenient for like this, has improved the precision that adds the fluence like this, has reduced the intensity of labour of experimenter simultaneously, and the practicality is good.
Description
Technical field
The utility model relates to instructional technology field, particularly relates to a kind of chemical experiment consumption tube stent.
Background technology
Graduated cylinder is a kind of measuring device used in laboratory, mainly uses glass, and minority (particularly large-scale) manufactures with transparent plastic.Purposes by volume quantitatively measures liquid, and graduated cylinder is perpendicular long cylindrical shape, on have mouth along side, be convenient to topple over.There is wide pin bottom to keep stable.Cylindrical wall is carved with volume range, reads volume for user.Maximum measurement volume is from several milliliters to a few liter.Barrel is printed on scale from bottom to top.During observed reading, it is equal with the lowest part (or highest point of meniscus) of the concave meniscus of liquid that experimenter will notice that sight line needs.
Graduated cylinder is used to a kind of glass apparatus measuring liquid volume, represents with the heap(ed) capacity that can measure (ml), and conventional has 10 ml, 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml etc.Graduated cylinder outer wall scale is all in units of ml, and the every little lattice of 10ml amount letter represent 0.2ml, and the every little lattice of 50ml graduated cylinder represent 1ml; Graduated cylinder is larger, caliber is thicker, its accuracy is less, the error in reading caused by the deviation of sight line is also larger, and in existing laboratory, graduated cylinder placement desktop carrying out the viewing that will realize horizontal direction in filling process, waist is watched so just to need experimenter curved, so just can guarantee the accurately close of adding amount, so not only improve the intensity in operating process, can not well improve filling precision simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of chemical experiment consumption tube stent.
The utility model is achieved through the following technical solutions:
A kind of chemical experiment consumption tube stent, comprise the support baseboard of rectangular structure, graduated cylinder, described support baseboard upper center is provided with the guide post vertically arranged, described guide post is provided with support set, described support set side is provided with horizontally disposed gripper shoe, and described gripper shoe side is provided with the fixed bar vertically arranged, described fixed bar side is provided with fixing card, described fixing card is connected with graduated cylinder, and described support set is connected with the adjusting rod output vertically arranged.
As optimal technical scheme of the present utility model, described support set cover on the guide bar.
As optimal technical scheme of the present utility model, described adjusting rod is cylinder or hydraulic cylinder.
As optimal technical scheme of the present utility model, described fixing card is elastic card.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model blocks by arranging guide post, gripper shoe, adjusting rod and fixing, during such use, graduated cylinder is placed on the supporting plate, then be fixed by fixing card, experimentally adjusting rod length elongation makes gripper shoe move up along guide post by the height of person, be convenient to experimenter's level like this and carry out viewing graduated cylinder, which enhance the precision of adding amount, reduce the labour intensity of experimenter simultaneously, practicality is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. support baseboard; 2. graduated cylinder; 3. guide post; 4. support set; 5. adjusting rod; 6. gripper shoe; 7. fixed bar; 8. fixing card.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of chemical experiment consumption tube stent, comprise the support baseboard 1 of rectangular structure, graduated cylinder 2, described support baseboard 1 upper center is provided with the guide post 3 vertically arranged, described guide post 3 is provided with support set 4, and wherein said support set 4 is enclosed within guide post 3.Described support set 4 side is provided with horizontally disposed gripper shoe 6, and described gripper shoe 6 side is provided with the fixed bar 7 vertically arranged, described fixed bar 7 side is provided with fixing card 8, and wherein said fixing card 8 is elastic card, can be fixed like this to graduated cylinder 2.Described fixing card 8 is connected with graduated cylinder 2, and described support set 4 is connected with adjusting rod 5 output vertically arranged, wherein said adjusting rod 5 is cylinder or hydraulic cylinder, and the height that can realize gripper shoe 6 like this regulates.
Its detailed description of the invention is: when using like this, graduated cylinder 2 is placed in gripper shoe 6, then be fixed by fixing card 8, experimentally adjusting rod 5 length elongation makes gripper shoe 6 move up along guide post 3 by the height of person, be convenient to experimenter's level like this and carry out viewing graduated cylinder 2, which enhance the precision of adding amount, reduce the labour intensity of experimenter simultaneously, practicality is good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
