Detailed description of the invention
Embodiment: shown in composition graphs 1-7, the drive end bearing bracket 2 the invention provides a kind of specific embodiment of direct insertion high pressure injector syringe erecting device, it comprises syringe 1, allowing syringe 1 to pass, be set on syringe 1 and the cranse 3 fixed by drive end bearing bracket 2, for cranse 3 is fixed to the pad 4 of drive end bearing bracket 2, the slot circle 5 be set on syringe 1, the torsion film 6 be fixed on slot circle, collecting slot circle 5 cylinder seat 7 of fixing syringe 1, with the base plate 8 coordinated bottom cylinder seat 7 and the stud 9 that drive end bearing bracket 2, cylinder seat 7, base plate 8 are fixed and nut 10.Wherein syringe 1 number is preferably two or more.
As shown in Figure 3, syringe 1 is provided with baffle ring 11, conical boss 12 and flange 13.Baffle ring 11 is positioned at syringe middle and lower part and spacing for syringe, flange 13 preferably two and be symmetrical arranged.One end of flange 13 is tip, is convenient to insert in slot circle 5, and the other end is connected with conical boss 12.
As shown in Figure 4, drive end bearing bracket 2 is provided with syringe hole and lateral symmetry has cranse groove 21, and cranse groove 21 tie spacer 4 is together for holding cranse 3.Cranse groove 21 minor axis is provided with cranse bearing track 22, for retraining the motion of cranse upper bearing (metal).Hole 23 is spacer screw hole, and boss hole 24 is stud screw hole.
As shown in Figure 5, cranse 3 is preferably high-strength high-elasticity nylon material, and ovalize.Be provided with chamfering 34 inside one end face 31 of cranse 3, make hole length d1 in this end face minor axis slightly larger than syringe end external diameter, be preferably greater than 1mm, be convenient to syringe and insert.Other end 32 is without chamfering, and in this end face 32 minor axis, hole length d2 is slightly less than syringe end external diameter, is preferably less than 2mm.Cranse 3 minor axis two ends are provided with cranse flange, and cranse flange is fixed with bearing 34.Under the effect of slot circle 5, by applying external force to bearing 34, cranse 3 is out of shape, increase minor axis length, cancellation cranse 3 retrains, and facilitates extracting of syringe 1.
As shown in Figure 6, slot circle 5 inner ring is provided with a circle draw-in groove 51, for blocking the flange 13 of syringe 1 bottom, makes it together can rotate with syringe 1.Draw-in groove 51 top is preferably wedge angle, facilitates barrel flange 13 to insert.Slot circle 5 one end face has grooved tracks 52, for retraining the bearing 34 on cranse 3, when slot circle 5 rotating, making bearing 34 along grooved tracks 52 and moving under the constraint of the cranse bearing track 22 of drive end bearing bracket 2, supportting large cranse 3.Be provided with a slot circle flange 53 outside slot circle 5, slot circle flange 53 is for installing fixing torsion film 6.
Torsion film 6 one end is fixed on slot circle flange 53 by the hole on it, and the other end is then enclosed within the torsion film column 72 on cylinder seat 7.
As shown in Figure 7, cylinder seat 7 is provided with the slot circle groove 71 for holding described slot circle 5 and torsion film 6, and torsion film column 72 for installing torsion film 6, and is provided with stud through hole 73.
Stud 9 one end is fixed on drive end bearing bracket 2, and base plate 8, cylinder seat 7 are fixed together by nut by one end.
Syringe installing/dismounting process is as follows:
When installing syringe 1, the syringe hole directly aimed at syringe bottom on drive end bearing bracket 2 is inserted, without the need to rotating or keeping special angle.During insertion, just started syringe bottom and can first touch on the chamfering inclined-plane of cranse 3 one end face 31 being arranged in drive end bearing bracket 2, because the minor axis length d1 of cranse 3 is slightly less than external diameter bottom syringe 1, when syringe 1 just inserts along inclined-plane, cranse 3 can be stretched.After syringe 1 inserts certain distance, namely cranse 3 starts to contact with the conical boss 12 of syringe, and now syringe 1 continues to insert, and cranse 3 is stretched further under the effect of conical boss 12.When the bottom of conical boss 12 is through cranse 3, because cranse 3 does not now retrain being subject to conical boss 12, cranse 3 can be retracted at once under itself elastic reaction, thus block syringe 1, now, the baffle ring 14 of syringe just in time also moves on the front end face of drive end bearing bracket 2, stops that syringe 1 inserts further, so far syringe 1 is completely fixed, syringe installation.
When dismantling syringe 1, hold syringe 1 clockwise shearing certain angle, preferably 45 degree.When syringe 1 rotates, the flange 13 of syringe 1, owing to being stuck in the draw-in groove 51 on slot circle 5, by its circumference constraint, can drive slot circle 5 together to rotate with syringe 1.Slot circle 5 when rotated, the bearing 34 on cranse 3 can be driven, make it along slot circle grooved tracks 52 and move under the constraint of drive end bearing bracket cranse bearing track 22, thus support large cranse 2, until cranse minor axis length d2 is greater than syringe boss 12 diameter, conical boss 12 is not retrained by cranse 2, and now syringe 1 just can take out smoothly.So far, syringe has been dismantled.
Certain above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the spirit of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
