Detailed description of the invention
Embodiment: shown in composition graphs 1-6, the utility model provides a kind of specific embodiment with the high pressure injector syringe erecting device of spring, it comprises syringe 1, removably fix the cylinder seat 2 of syringe 1, be arranged on cylinder seat 2 and monitor optical chopper module 3 that whether syringe 1 be in place, be arranged on bottom 4 bottom cylinder seat 2, bottom contacts with bottom 4 and the spring 5 of being accommodated by cylinder seat 2 inner chamber and the back-up ring 6 with the tip contact of spring 5.
Preferably arrange two flanges 12 bottom syringe 1, as shown in Figure 5, cylinder seat 2 is provided with grooved tracks 21, intermediate flange 22 and the flange rail 23 of accommodating flange 12.When installing syringe 1, flange 12 inserts cylinder seat 2 along grooved tracks 21, after syringe 1 is completely fixed, and the upper end face of flange 12 and the upper end face abutting contact of grooved tracks 21 end.When injecting, the upper end face of flange 12 and the upper end face of grooved tracks 21 end are driving surface, need to bear the antagonistic force that syringe 1 is injected forward; When inhaling medicine, the bottom surface of flange 12 and the bottom surface of grooved tracks 21 end are driving surface, need to bear the antagonistic force inhaling syringe 1 inner plunger friction force in medicine process.Constant slope is arranged at flange 12 bottom, conveniently finds and inserts the flange rail 23 be arranged on cylinder seat 2.Grooved tracks 21 extends at least in the two directions, i.e. the axial and circumferential both direction of syringe 1.
When syringe 1 prepares to insert cylinder seat 2, flange 12 first inserts cylinder seat 2 along flange rail 23 straight line, is then inserted into assigned address along grooved tracks 21 by setting track.Intermediate flange 22 lower surface contacts with back-up ring 6, plays to the spacing effect of back-up ring 6.If high pressure injector is monotubular, cylinder seat 2 is one; If Binocular High-pressure Syringe, as embodiment, cylinder seat 2 be two side-by-side, middle to be linked together by connecting portion.Cylinder seat 2 lower interior portion hollow, pref. cylindrical, for laying back-up ring 6 and spring 5, flange rail 23 upper end has larger chamfering, is convenient to flange 12 and finds and insert.
Optical chopper module 3, is made up of light teasel root device and circuit card, and the welding of light teasel root device on circuit boards, is communicated with central controller by the interface on circuit card.Another effect of circuit card, makes light teasel root device be fixed on cylinder seat 2 by it.
Back-up ring 6 according to the hollow shape of cylinder seat 2 bottom, circular.The lower surface of back-up ring 6 is connected with spring 5, and in its natural state, spring 5 is in compressive state, and namely the upper surface of back-up ring 6 coordinates with intermediate flange 22, for spacing.When syringe 1 inserts cylinder seat 2, syringe bottom end face starts to contact with back-up ring 6, during insertion, syringe 1 can constantly by back-up ring 6 Compress Spring 5, when syringe 1 rotates to assigned address, flange 12 can stick into the end of grooved tracks 21 under the effect of spring 5, completes syringe and installs.
Spring 5 one end connects back-up ring 6, and one end connects bottom 4, is fixed in cylinder seat bottom aerial.
Bottom 4 is fixed by screws in bottom syringe 2.
When syringe 1 inserts cylinder seat 2, first the flange 12 being positioned at syringe 1 bottom is aimed at the flange rail 23 be positioned on cylinder seat 2, also can rotate to an angle when inserting syringe 1, making flange 12 find flange rail 23, then inserting.When flange 12 insert enter grooved tracks 21 after flange rail 23 time, syringe 1 can the track that set along grooved tracks 21, under the effect of flange 12, while inserting, rotates to cylinder seat 2.In a certain moment of insertion process, syringe bottom face starts to contact with back-up ring 6, and when continuing to insert, syringe 1 can by back-up ring 6 Compress Spring 5.When flange 12 arrives grooved tracks 23 end, flange 12 can stick into the upper end of grooved tracks 23 end under the action of the spring and fix.Now optical chopper can detect that flange 12 has been moved to position, and sends a signal to central controller, illustrates that syringe 1 is in place, can carry out bottom operation.During syringe dismounting, only need inside for a syringe top, the opposite spin then along installation direction can be extracted.
Certain above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
