Abstract
The utility model aims at designing an annular burette rack convenient to observe. The annular burette rack is characterized in that a rack body is provided with a base, a vertical bar, an annular clamping bar, a longitudinal clamping bar, a burette clamp and a bottom lining plate; the annular clamping bar is provided with a bracket, the center of the bracket is provided with a long screw with a rotating shaft, and the long screw is connected with the vertical bar and the annular clamping bar on the top end; the longitudinal clamping bar is arranged below the annular clamping bar, and the rear end part of the longitudinal clamping bar is connected to the vertical bar through screws; the vertical bar is fixed on the center of the base through screws of the base; one surface, opposite to the longitudinal clamping bar, of the base of the multi-head burette rack is provided with an arc groove, and the bottom lining plate is embedded in the arc groove. The annular burette rack has the advantages that a plurality of burettes can be simultaneously clamped through the combination of the multi-head burette rack and the bottom lining plate, so that the space is saved, and the mess of the titration process in a laboratory can be avoided; the base is provided with the bottom lining plate, so that the data is convenient to read.
Description
Technical field
The utility model relates to a kind of chemical apparatuses, particularly a kind of ring type buret stand of convenient observation.
Background technology
General buret stand is generally by base, and double-ended clip and montant form, and can only press from both sides two burets of soda acid, can not meet much physics and chemistry, medical treatment, the needs in the laboratories such as biology.When some laboratory needs many burets to test sometimes, certainly will need a plurality of buret stands, like this, both increase experiment equipment, easily cause again laboratory numerous and diverse in disorder.And in laboratory, observe read liquid in buret concrete ooze scale value, be one of experiment important way of obtaining data.Common laboratory does not have the bottom lining plate reading of comparing in addition, easily cause reflective, the multiple inconvenience such as background color is undesirable.
Summary of the invention
The purpose of this utility model is to design a kind of ring type buret stand of convenient observation, to solve the problems such as the numerous and diverse in disorder and reflective background color of observation burette reading in laboratory is undesirable.
The technical solution of the utility model: a kind of ring type buret stand of convenient observation, is characterized in that: support body is provided with base montant, annular clamping bar, vertical clamping bar, buret clamp and bottom lining plate; Annular clamping bar is provided with shelf, the central authorities of shelf be one with the long spiro nail of rotating shaft, long spiro nail connects the annular clamping bar on montant and its top; Vertical clamping bar is located at the below of annular clamping bar, and its rearward end is connected on montant with screw; Base center is fixed wtih montant by base screw, and montant and annular clamping bar, vertical clamping bar are vertical, and annular clamping bar, vertical clamping bar are parallel with base; On annular clamping bar, fix a plurality of stand-by buret clamps, the fixing single buret clamp of vertical clamping bar front end; One side over against vertical clamping bar on the base of Multi-head burette stand is provided with deep-slotted chip breaker, and on deep-slotted chip breaker, bottom lining plate in embedding.
The ring type buret stand of convenient observation as above, is characterized in that: on its bottom lining plate, have a milky frosted coating, the outside of white coating is also provided with the acid and alkali-resistance coating of layer of transparent.
The ring type buret stand of convenient observation as above, is characterized in that: there is a support its bottom lining plate top, and support one end is provided with end slot on bottom lining plate, and the other end is provided with screw and montant is fixed.
Superiority of the present utility model: because the combination of Multi-head burette stand and bottom lining plate can be pressed from both sides many burets simultaneously, saved space, avoided titration process in laboratory to take up an area numerous and diverse in disorder.Every buret can be used flexibly.When a large amount of titration operation of the more loaded down with trivial details need of experiment, every group of buret stand can operate for two to three people simultaneously simultaneously.Base is provided with bottom lining plate and facilitates reading out data.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Wherein: the 1st, base, the 2nd, base screw, the 3rd, bottom lining plate, the 4th, buret pipe clamp, the 5th, annular clamping bar, the 6th, the shelf on annular clamping bar, the 7th, the long spiro nail at annular clamping bar shelf center, the 8th, montant, the 9th, vertical clamping bar, the 10th, the deep-slotted chip breaker on base, the 11st, bottom lining plate support.
The specific embodiment
As accompanying drawing shows: a kind of ring type buret stand of convenient observation, is characterized in that: support body is provided with base 1 montant 8, annular clamping bar 5, vertical clamping bar 9, buret clamp 4 and bottom lining plate 3; Annular clamping bar is provided with shelf 6, the central authorities of shelf 6 be one with the long spiro nail 7 of rotating shaft, long spiro nail 7 connects the annular clamping bar 5 on montants 8 and its top; Vertical clamping bar 9 is located at the below of annular clamping bar 5, and its rearward end is connected on montant 8 with screw; Base 1 center is fixed wtih montant 8 by base screw 2, and montant 8 and annular clamping bar 5, vertical clamping bar 9 are vertical, and annular clamping bar 5, vertical clamping bar 9 are parallel with base 1; On annular clamping bar 5, fix a plurality of stand-by buret clamps 4, the fixing single buret clamp 4 of vertical clamping bar 9 front ends; One side over against vertical clamping bar 9 on the base 1 of Multi-head burette stand is provided with deep-slotted chip breaker 10, and on deep-slotted chip breaker 10, bottom lining plate 3 in embedding.
The ring type buret stand of convenient observation as above, is characterized in that: on its bottom lining plate 3, have a milky frosted coating, the outside of white coating is also provided with the acid and alkali-resistance coating of layer of transparent.
The ring type buret stand of convenient observation as above, is characterized in that: there is a support 11 its bottom lining plate 3 tops, and support 11 one end are provided with end slot on bottom lining plate 3, and the other end is provided with screw and montant 8 is fixing.
