Abstract
The utility model provides a kind of biological chemical reagent bottle cap, including lid, block and torsion shaft, the lid and block one end pass through the dynamic connection of torsion shaft axis, be equipped on the inside of lid for the fixed internal thread of body, it is hollow structure at the top of block, polytetrafluoroethylene film is fixed at the hollow structure；The biological chemical reagent Bottle cap structure is simple, acid and alkali-resistance, organic solvent corrosion, the functions such as control air-tightness, water proofing property can be reached by adjusting the elastic of bottle cap upper cover body, be easily opened while sealing secured, greatly reduce security risk present in laboratory.
Description
Technical field
The utility model is related to laboratory equipment field, especially a kind of biological chemical reagent bottle cap.
Background technology
Biology, chemical laboratory can use the liquid such as various acid, alkali, organic solvent, they are contained in glass or modeling
Expect bottle in, and current lid be also broadly divided into glass, two kinds of materials of plastics lid.Glass lid air-tightness, water proofing property are not
It is good, it the problems such as corrosion that plastics lid is subject to acid, alkali, organic solvent finally also will appear air-tightness, the moisture absorption, loosening, makes
At the security risk for also becoming laboratory in bottle while reagent contamination.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of biological chemical reagent bottle caps.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of biological chemical reagent bottle cap, including lid, block and torsion shaft, the lid and block one end pass through overturning
The dynamic connection of axis axis, be equipped on the inside of lid for the fixed internal thread of body, be hollow structure at the top of block, at the hollow structure
It is fixed with polytetrafluoroethylene film.
Preferably, the material of above-mentioned biological chemical reagent bottle cap, the lid is polytetrafluoroethylene (PTFE).
Preferably, above-mentioned biological chemical reagent bottle cap, the lid outer ledge are equipped with anti-skid chequer.
Advantageous effect：
Above-mentioned biological chemical reagent bottle cap, simple in structure, acid and alkali-resistance, organic solvent corrosion, can be by adjusting bottle cap upper cover
The elastic of body reaches the functions such as control air-tightness, water proofing property, is easily opened, is greatly reduced in laboratory while sealing secured
Existing security risk.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of biological chemical reagent bottle cap provided by the utility model.
In figure：1- lid 2- anti-skid chequer 3- torsion shaft 4- block 5- polytetrafluoroethylene films
Specific implementation mode
Embodiment 1
As shown in Figure 1, the biological chemical reagent bottle cap, including lid 1, block 4 and torsion shaft 3, the lid and lid
Cap one end is by the dynamic connection of torsion shaft axis, and the material of the lid is polytetrafluoroethylene (PTFE), and lid outer ledge is equipped with anti-skid chequer 2,
Be equipped on the inside of lid for the fixed internal thread of body, be hollow structure at the top of block, poly- four be fixed at the hollow structure
Fluoride film 5, the polytetrafluoroethylene film not only high resilience, but also there is waterproof, air-locked function, block is being closed
The elasticity that lid screw thread is adjusted under state, lid top edge is protruded from by rear bottleneck top edge, utilizes polytetrafluoro at the top of block
The elasticity of vinyl film makes it fit closely fixation with bottleneck top edge, forms closed structure, when constantly screwing bottle cap, bottleneck top
Edge projecting height is higher, is bonded with Bottle cap top closer, reaches waterproof, air-locked purpose.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
