Description
Technical Field
The utility model relates to a burette rack provides a scalable burette rack very much.
Background
In the laboratory, burettes are widely used, in particular in the laboratory project of the volumetric method. However, there are certain problems with the placement and storage of the burette after use. As is known, burettes are essentially glass products, are fragile and have a certain length. If the storage is improper, the storage can be broken, and the single placement occupies too much space. The existing burette rack is generally formed by combining an iron stand table and a butterfly clamp, and can only be used for placing two burettes generally, so that the storage requirement of the laboratory daily burette cannot be met.
The prior burette rack can store a small number of burettes and occupies a large space, and a large number of items in the experiment of a general laboratory volumetric method need to use special burettes, so that the burette rack which can store a large number of burettes and save the space is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a scalable burette rack makes depositing of buret more practice thrift the space, and is safer. The utility model discloses utilize parallelogram's instability, make a plurality of parallelogram telescopic burette framves. The burette storage space is saved, the cost is low, and the problem of difficult storage of the burette can be solved.
The technical scheme of the utility model is that: a collapsible burette rack, comprising: the device comprises a base 1, a support column 2, a telescopic burette frame body 3, a burette fixing clamp 4 and a support block 5; scalable burette rack body 3 is the parallelogram telescopic machanism that constitutes through several connecting rod 3a and round pin axle 3b, support column 2 is located to two intercrossing's at scalable burette rack body 3 middle part connecting rod 3a cover, tray 5 is fixed on support column 2 and holds scalable burette rack body 3, 2 bottom mounting of support column are on base 1, the connecting rod 3a outside of scalable burette rack body 3 is equipped with burette fixation clamp 4.
Preferably, the burette fixing clamp 4 is formed by fixing a cylindrical connecting pipe fitting 4a and a burette seat 4b in a crossed manner, and both the connecting pipe fitting 4a and the burette seat 4b are provided with buckles; the connecting pipe fitting 4a is sleeved on the connecting rod 3a, and the burette seat 4b is used for storing a burette.
Preferably, the base 1 is a marble base.
Preferably, scalable burette rack body 3 and burette mounting clip 4 are the plastics material.
The utility model discloses following profitable effect has:
the utility model is suitable for a laboratory acid-base buret is deposited, and is different with buret rack in the past, the utility model discloses a plurality of burets can be once only deposited to the scalable buret rack, have solved the difficult problem that laboratory buret was deposited. The utility model discloses simple structure saves space, and it has comparatively huge economic value and social value.

fig. 2 is a schematic structural view of a frame body of the retractable burette frame of the present invention;
FIG. 3 is a schematic structural view of a burette retainer clip according to the present invention;
in the figure: 1. a base; 2. a support pillar; 3. a telescopic burette frame body; 3a, a connecting rod; 3b, a pin shaft; 4. a burette fixing clamp; 4a, connecting pipe fittings; 4b, a titration tube seat; 5. and (7) supporting blocks.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-3, a collapsible burette stand comprises: the device comprises a base 1, a support column 2, a telescopic burette frame body 3, a burette fixing clamp 4 and a support block 5; scalable burette rack support body 3 is the parallelogram telescopic machanism who constitutes through several connecting rod 3a and round pin axle 3b, and support column 2 is located to two intercrossing's at scalable burette rack support body 3 middle part connecting rod 3a cover, and the tray 5 is fixed on support column 2 and holds scalable burette rack support body 3, and 2 bottom mounting of support column are on base 1, and the connecting rod 3a outside of scalable burette rack support body 3 is equipped with burette fixation clamp 4.
The burette fixing clamp 4 is formed by fixing a cylindrical connecting pipe fitting 4a and a burette seat 4b in a crossed manner, and the connecting pipe fitting 4a and the burette seat 4b are both provided with buckles, so that the burette is convenient to open and close; the connecting pipe fitting 4a is sleeved on the connecting rod 3a, and the burette seat 4b is used for fixedly storing the burette.
The base 1 is a marble base, the base is heavy, the center of gravity is stable, and the stability of the base when a plurality of burettes are placed can be guaranteed.
The telescopic burette frame body 3 and the burette fixing clamp 4 are made of plastic materials, the plastic materials are important organic synthetic polymer materials, the application is very wide, most of the plastic materials are light, and the plastic materials have the advantages of stable chemical property, no corrosion, good impact resistance, good transparency and abrasion resistance, good insulativity, low thermal conductivity, good general formability and colorability, low processing cost and the like.
