Abstract
It the utility model is related to a kind of anti-dropout connecting tube, anti-dropout connecting tube is Y-shaped hollow tube, including supervisor and branch pipe, there is supervisor to be open on supervisor, there is branch tube opening on branch pipe, be additionally provided with supervisor's inner tube in supervisor's opening, branch pipe inner tube is additionally provided with branch tube opening, it is supervisor's groove between supervisor's opening and supervisor's inner tube, is branch pipe groove between branch tube opening and branch pipe inner tube.The utility model uses the structure of outer tube sleeve inner tube, the mode being combined using interior extrapolation bonding instead of original interpolation and be bonded, it compensate for the deficiencies in the prior art, and using interference fit between flexible pipe and inner tube, grip between adding both it, make connection more firm, reduce manufacturing scrap rate and percent defective.
Description
Technical field
A kind of anti-dropout connecting tube is the utility model is related to, for medical infusion pipeline class product.
Background technology
Medical clinical pipeline apparatus can usually add one or more connecting tubes in its product, and major function is to pipe
Liquid medicine injection in road, in production, then need to be bonded flexible pipe at the both ends of the connecting tube, existing frequently-used way is by connecting tube
Interface internal diameter match with hose outside diameter, will in flexible pipe inject connecting tube in, but in practical operation this way bonding force
It is and bad.Connecting tube is mostly that hard material makes, and certain error can be produced in injection, and flexible pipe typically uses expressing technique,
Certain error amount is had, although the error very little of the two parts, even tiny error when the two interior grafting coordinates
Faying face can be caused space occur, make bonding insecure, the defective work of higher proportion is just had when producing and detecting, is caused
Production wastes.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of anti-dropout connecting tube, using in outer tube sleeve
The structure of pipe, the mode being combined using interior extrapolation bonding instead of original single interpolation bonding way, compensate for existing skill
The deficiency of art, and the grip between adding both it, make connection more firm using interference fit between flexible pipe and inner tube, reduce
Manufacturing scrap rate and percent defective.
The utility model is purpose belonging to realization, and used technical scheme is：A kind of anti-dropout connecting tube, the anticreep
It is Y-shaped hollow tube to fall connecting tube, including supervisor and branch pipe, has supervisor to be open on supervisor, has branch tube opening, the master on branch pipe
Supervisor's inner tube is additionally provided with tube opening, branch pipe inner tube is additionally provided with branch tube opening, it is recessed to be responsible between supervisor's opening and supervisor's inner tube
Groove, it is branch pipe groove between branch tube opening and branch pipe inner tube.
The beneficial effects of the utility model are：Using the structure of outer tube sleeve inner tube, the side being combined using interior extrapolation bonding
Formula instead of original single interpolation bonding way, compensate in the prior art, because bonding plane is endless caused by forming errors
It is whole, the impaired deficiency of adhesive strength, and the grip between adding both it, more protected using interference fit between flexible pipe and inner tube
The adhesive strength between flexible pipe and connecting tube has been demonstrate,proved, has made connection more firm, manufacturing scrap rate has been reduced and percent defective subtracts significantly
It is small to waste.

Embodiment
As Figure 1-3, a kind of anti-dropout connecting tube, the anti-dropout connecting tube 1 are Y-shaped hollow tube, including supervisor
1-1 and branch pipe 1-2, being responsible on 1-1 to have on supervisor's opening 1-1-1, branch pipe 1-2 has branch tube opening 1-2-1, supervisor's opening 1-
It is additionally provided with 1-1 in supervisor inner tube 1-1-2, branch tube opening 1-2-1 and is additionally provided with branch pipe inner tube 1-2-2, supervisor opening 1-1-1 and master
It is supervisor groove 1-1-3 between pipe inner tube 1-1-2, is branch pipe groove 1-2-3 between branch tube opening 1-2-1 and branch pipe inner tube 1-2-2.
As shown in figure 4, in the production of extrusion infusing pipeline, using being responsible for groove 1-1-3 and branch pipe groove 1-2-3 by flexible pipe and company
Adapter is bonded together, and flexible pipe extrapolation is adhered in inner tube, and inner tube external diameter is slightly larger than inner diameter, and interference is formed between making both it
Coordinate, form certain grip, supervisor's opening 1-1-1 and branch tube opening 1-2-1 is coated at outside flexible pipe, and this structure is also certain
The deformation of flexible pipe is limited in degree, reduces the probability that comes off.
As seen in figs. 5-6, bonding way of the prior art is bonded for traditional interpolation, but this way in practical operation
Bonding force and bad.Connecting tube is mostly that hard material makes, and certain error can be produced in injection, flexible pipe is typically using extrusion
Technique, certain error amount is also had, it is when the two interior grafting coordinates even tiny although the error very little of the two parts
Error also results in faying face and space occurs, makes bonding insecure, and the defective work of higher proportion is just had when producing and detecting,
Production is caused to waste.
The utility model uses the structure of outer tube sleeve inner tube, and the mode being combined using interior extrapolation bonding instead of original
Single interpolation bonding, compensate in the prior art, and because bonding plane is imperfect caused by forming errors, adhesive strength is impaired not
Foot, and the grip between adding both it, more be ensure that between flexible pipe and inner tube using interference fit between flexible pipe and connecting tube
Adhesive strength, make connection more firm, reduce manufacturing scrap rate and percent defective substantially reduces waste.
