The purpose of this utility model be exactly for prior art exist deficiency and a kind of PCR pipe lid improving sealing effectiveness, open and close rapid operation is provided.
To achieve these goals, the technical solution adopted in the utility model is:
PCR pipe lid, it includes sheet lid, and lid lower surface is one-body molded downwards pipe lid, and pipe lid is the hollow tubular structure of top seal bottom opening, and pipe lid circumferential exterior surface is coated with one deck flexible glue layer.
Described flexible glue layer between pipe lid by the one-body molded mode of double-material injection-molding in conjunction with formation integral structure.
The material of described sheet lid and pipe lid is PP or COC.
The material of described flexible glue layer is TPV, TPE or TPU.
Described pipe is stamped multiple, and multiple pipe lid linearly mode or matrix-style is distributed on lid.
Position on described lid between adjacent two pipe lids offers avoiding hollow groove respectively, and the both sides of avoiding hollow groove form arc elastic connecting strip respectively.
Position corresponding with pipe lid circumferential exterior surface on described lid offers multiple along the through hole that distributes of pipe lid circumference, the material at flexible glue layer top respectively by multiple through hole through extending lid upper surface and being interconnected to form loop connecting portion.
The internal diameter of described connection section is greater than the external diameter of pipe lid.
The position corresponding with pipe lid, described lid upper surface offers groove, and connecting portion is in groove.
The thickness that described flexible glue layer is positioned at base section from top to bottom increases progressively.
The utility model beneficial effect is: the utility model includes sheet lid, lid lower surface is one-body molded downwards pipe lid, pipe lid is the hollow tubular structure of top seal bottom opening, pipe lid circumferential exterior surface is coated with one deck flexible glue layer, the utility model increase flexible glue layer utilize its elastic performance can with the mouth of pipe of PCR pipe more close contact realize sealing, good sealing effect, sealing is reliable, and only need less engaging dynamics just can reach required sealing effectiveness between pipe lid and the mouth of pipe of PCR pipe, only need to use smaller power just energy open and close pipe lid, operate more laborsaving, open and close operation comfort is good, in addition between flexible glue layer with pipe lid by the one-body molded mode of double-material injection-molding in conjunction with formation integral structure, make to combine more closely between flexible glue layer and pipe lid, more firm, sealing effectiveness is better, sealing is more reliable.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is decomposing schematic representation of the present utility model.
Fig. 3 is fragmentary sectional view of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described, see shown in Fig. 1 ~ 3, PCR pipe lid, it includes sheet lid 1, lid 1 lower surface is one-body molded downwards pipe lid 11, pipe lid 11 is the hollow tubular structure of top seal bottom opening, and pipe lid 11 circumferential exterior surface is coated with one deck flexible glue layer 2.Between flexible glue layer 2 with pipe lid 11 by the one-body molded mode of double-material injection-molding in conjunction with formation integral structure, make to combine more closely between flexible glue layer 2 and pipe lid 11, more firm, sealing effectiveness is better, sealing is more reliable.
Sheet lid 1 is PP or COC with the material of pipe lid 11, has good comprehensive physical performance, is more suitable for medical treatment, medicine, gene and protein research, biological study, drug development laboratories and other biological technology application.COC is cyclic olefine copolymer, is a kind of transparent copolymerized macromolecule of amorphism of cyclic olefin structure.The material of flexible glue layer 2 is TPV, TPE or TPU, has good elasticity and compression deformability, resistance to environment, ageing resistance, excellent resistance to permanent deformation performance, and tensile strength, high tenacity and high resilience improve the sealing effectiveness between pipe lid 11 and PCR pipe.By the flexible glue layer 22 of TPV, TPE or TPU material and the lid 1 of PP or COC material by the one-body molded mode of double-material injection-molding in conjunction with formation integral structure, make the utility model have good comprehensive physical performance, there is again better sealing property.
Pipe lid 11 has multiple, multiple pipe lid 11 linearly mode or matrix-style is distributed on lid 1, if pipe lid 11 can be 8,12, arrange in single mode, pipe lid 11 also can be 24,48,96 or other quantity, arrange in a matrix fashion, can be applicable to multiple PCR pipe, pipe lid 11 is 8 in the present embodiment.
Position on lid 1 between adjacent two pipe lids 11 offers avoiding hollow groove 12 respectively, the both sides of avoiding hollow groove 12 form arc elastic connecting strip 13 respectively, make lid 1 have certain recoverable deformation space, can increase or shorten the distance between adjacent two pipe lids 11 as required voluntarily.
Position corresponding with pipe lid 11 circumferential exterior surface on lid 1 offers multiple through hole 14 distributed along pipe lid 11 circumference, the material at flexible glue layer 2 top respectively by multiple through hole 14 through extending lid 1 upper surface and being interconnected to form loop connecting portion 21, lid 1 is clipped in the middle by loop connecting portion 21 and pipe lid 11, flexible glue layer 2 is combined into one with pipe lid 11 and lid 1 better, in conjunction with more firm, improve the shear strength of flexible glue layer 2.
The internal diameter of connection section 21 is greater than the external diameter of pipe lid 11, and the position corresponding with pipe lid 11, lid 1 upper surface offers groove 15, and connection section 21 is arranged in groove 15, and flexible glue layer 2 is combined into one with lid 1, better in conjunction with more firm.The thickness that flexible glue layer 2 is positioned at base section from top to bottom increases progressively, improve bottom flexible glue layer 2 and between the PCR pipe mouth of pipe in conjunction with compactness, improve sealing effectiveness.
The utility model increase flexible glue layer 2 utilize its elastic performance can with the mouth of pipe of PCR pipe more close contact realize sealing, good sealing effect, sealing is reliable, and only need less engaging dynamics just can reach required sealing effectiveness between pipe lid 11 and the mouth of pipe of PCR pipe, only need to use smaller power just energy open and close pipe lid 11, operate more laborsaving, open and close operation comfort is good.
