Description
Technical field
The present invention relates to detection technique field, specifically a kind of bracket for the packed coliform test scraps of paper.
Background technique
Coliform is that a group can make lactose fermentation in 37 DEG C or 44 DEG C growths, and the interior acid that produces produces the aerobic and simultaneous of gas for 24 hours
The Gram-negative of oxygen is without spore bud bacillus.The generally title " total coli group " of the culture growth at 37 DEG C, in the title that 44 DEG C grow
" excrement colibacillus group ".Coliform is the indicator bacteria of the homoiothermies animal intestinal tract pollutant such as the mankind, poultry, and response sample is by excrement dirt
Dye the case where.
Coliform test paper is adsorbed in the sterile of certain area using quantitative lactose and indicator and nutritional ingredient etc.
On filter paper, when bacterial reproduction, the biochemical reaction of coliform makes indicator discoloration to whether contain large intestine in judgement sample
Flora.With bromocresol purple and TTC（2,3, 5-Triphenyltertrazoliumchloride）For：Producing acid reduces pH value, bromocresol purple instruction
Agent is turned yellow color by purple.Meanwhile the corresponding dehydrogenase of gas generation process, within the scope of suitable pH, TTC is changed in catalysis substrate dehydrogenation
Form red insoluble TTF（San Ben formazan）, i.e., spot is displayed in red in the case where producing the yellow background after acid（Or blush）.Pass through
Above indicator variation judges whether there is the sour gas generation process of production, has determined whether（Excrement）The presence of coliform.According to
The inquiry of MPN table calculates corresponding（Excrement）The concentration of coliform.
The coliform test scraps of paper are the consumptive materials applied to method for rapidly testing of projects such as excrement colibacillus groups in water, are one
Kind batch cultur base product well prepared in advance, is widely used in food, environmental testing.Its bag-shaped flexible package form is outstanding
It is multi-joint bag-shaped flexible packaging form（Such as testing piece MPN counting method）It has the disadvantage that in use：First is that soft
Property material packaged configuration deformation, opening easily contacts other articles such as desktop, manpower, to introduce pollution；Second is that analysis personnel
It needs both hands to be used in combination when use, fix packing material on the other hand and unfolds sack, the other hand sampling sample-adding, when sample is more, operating procedure
It repeats, cumbersome inconvenience more；Third is that examining the scraps of paper to be inoculated with due to hand-held, fluid spills easily infect personnel by sample.Cause
This, designs a kind of bracket for the packed coliform test scraps of paper, is those skilled in the art's problem urgently to be resolved.
Summary of the invention
The technical problem to be solved by the present invention is to：A kind of bracket for the packed coliform test scraps of paper is provided, this

Below fixed non-skid band, the lateral opening length of V-type through-hole two is unequal；The press strip and pre- bracket are respectively arranged on transverse side
Fixation non-skid band and V-type through hole, press strip be in concave character type, press strip both ends are connected to the longitudinal side of pedestal, and press strip is in face of solid
The surface for determining non-skid band is equipped with mobile non-skid band, and pre- bracket passes through V-type through-hole and the elastic connection set on transverse side inside face
Mechanism connection；The longitudinal side of the pedestal is equipped with strip through-hole, and strip through-hole includes horizontal segment and vertical section, press strip both ends
It is connected by strip through-hole with longitudinal side.
The flexible connection mechanism includes fixing bolt, spring and eye bolt, and the fixing bolt is set to laterally
The top in lateral inner face, spring one end are connected and fixed bolt, and the spring other end connects eye bolt, and eye bolt runs through V-type
Through-hole is connected with pre- bracket.
Anti-skidding 20 ~ the 30mm of bandwidth of the fixation, mobile anti-skidding 10 ~ 20mm of bandwidth.
The angle of the V-type through-hole is 60~90 °.
The distance of one end of the V-type through-hole to intermediate endpoint is 20 ~ 30mm, the distance of the other end to intermediate endpoint for 6 ~
10mm。
The V-type through-hole is two, and the corresponding axis of two V-type through-holes is parallel to each other.
The pedestal, press strip and pre- bracket are heat-resisting PC, aluminium alloy or stainless steel materials.
The right-angled trapezium that the longitudinal side is 65 ° ~ 85 ° of acute angle
Compared to the prior art the present invention has the advantage that：
1, the present invention examines the scraps of paper due to providing support to flexible packaging using bracket, utilizes the fixation non-skid band and pressure on pedestal
Movement non-skid band on item clamps the inspection scraps of paper, makes non-skid band using the relative motion between pedestal and press strip and examines the scraps of paper
Friction is generated between packaging bag to open sack, keeps the test scraps of paper indeformable, is prevented its sack contact desktop and other items, is avoided
Pollution.
2, the bracket of this packed coliform test scraps of paper is used fixes instead of manpower, it is possible to reduce personnel operate and reduce
The risk that operator is infected by sample.
3, invention emulates the modes of manpower friction to unfold sack, disposably unfolds multiple sacks, simplifies repetition step
Suddenly, manpower and material resources are greatlyd save, the spending of experimental cost is reduced.
4, rack body of the present invention selects the heat proof materials such as PC, aluminium alloy or stainless steel materials, and removing can be whole after non-skid band
Body carries out high pressure sterilization, has reached multiple utilization, energy saving purpose.
