Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the utility model；Fig. 2 is the A of Fig. 1 to enlarged structure schematic diagram.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Anti- axial load separating experiment device described in the utility model includes pedestal 1, installs guide post 2 on pedestal 1, leads
Lifter plate 3 is installed on column 2, tensile test head 4 is installed on lifter plate 3, mark is installed in 1 top surface of pedestal of 4 lower section of tensile test head
Quasi- female Luer connector 5,4 lower end of tensile test head are connect with traction tube 6,6 lower part outer wall of traction tube be diameter from top to bottom
The truncated cone shape being gradually increased, the truncated cone shape lower end border offer multiple strip holes 8 along the setting of its axis direction, the truncated cone shape
Periphery wall is provided with external screw thread, and swivel nut 7 is installed in 6 periphery of traction tube, and 7 inner wall of swivel nut passes through internal screw thread and 6 lower, outer perimeter of traction tube
External screw thread cooperation, 6 side of traction tube installs lateral frame 9, and lateral frame 9 connect with longitudinal support 10, installs laser on longitudinal support 10
Transmitter 11.Before experiment, female Luer part 20 to be measured is connect with standard luer fittings connector 5, then makes lifter plate 3 along leading
It is moved down to column 2, female Luer 20 upper end of part to be measured is made to enter 6 lower part of traction tube, rotation swivel nut 7 moves it to 6 lower end of traction tube
It is dynamic, until 6 lower part of traction tube holds female Luer part 20 to be measured tightly.Laser emitter 11 can be outside female Luer part 20 to be measured at this time
A luminous point is irradiated on wall, experimenter can paste label paper on female Luer 20 outer wall of part to be measured, record the luminous point
Position.When experiment, tensile test head 4 applies the tractive force of standard to female Luer part to be measured 20, such as female Luer part 20 to be measured
It is opened with standard luer fittings connector 5, then can determine whether that the axial load resistance of female Luer part 20 to be measured is unqualified.
