Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-6 is please referred to, the utility model provides a kind of technical solution: a kind of connection connecting for injection plunger with injection rod Spindle, including the first connecting shaft body 1, screw rod 2, connecting tube 3, fixed block 4, second couple axis body 5, knob 6, limit hole 7, gag lever post 8 and groove 9, the first connecting shaft body 1 is internally provided with screw rod 2, and the outer surface of screw rod 2 is connected with connecting tube 3, and connecting tube 3 is logical It crosses fixed block 4 to be connected with the second connection axis body 5, and the second connection axis body 5 is set to the left and right sides of the first connecting shaft body 1, silk The top of bar 2 is fixedly installed with knob 6, and limit hole 7 is opened on knob 6, and limit hole 7 is internally connected with gag lever post 8, recessed Slot 9 is opened on the outer wall of the first connecting shaft body 1, and groove 9 is internally provided with fixed block 4；

Screw rod 2 is that bearing is connect, and screw rod 2 and the connection type of knob 6 are with the connection type of 1 inner wall of the first connecting shaft body Welding, and 7 equidistantly distributed of limit hole on knob 6 ensure that stability when screw rod 2 rotates, while rotating in knob 6 To certain angle, convenient for knob 6 is fixed by limit hole 7, knob 6 is effectively prevent the phenomenon that voluntarily rotating occur；

Connecting tube 3 and the connection type of screw rod 2 are to be threadedly coupled, and the thread rotary orientation of 2 upper and lower ends of screw rod is on the contrary, in this way When screw rod 2 rotates, 2 connecting tubes 3 while movement can be driven, to drive the second connection axis body 5 by connecting tube 3 It is displaced, is preferably attached fixation with injection plunger and injection rod；

Fixed block 4 couples axis body 5 with second and is an integral structure, and fixed block 4 passes through 1 structure of groove 9 and the first connecting shaft body At slide construction, the second connection axis body 5 can be kept mobile more by the sliding of fixed block 4 when the second connection axis body 5 is mobile Add steady；

Second connection axis body 5 is provided with two groups, and there are two every group second connection axis body 5 settings, and 2 second connections Axis body 5 is sector structure, while 2 group of second connection axis body 5 is symmetrical about the longitudinal centre line of the first connecting shaft body 1, just It is attached in the injection plunger and injection rod with different-diameter size, increases the practicability of the coupling spindle, be also staff Operation offer convenience；

Second connection axis body 5 includes fixed plate 501, cushion block 502 and reinforcing rib 503, and is bonded on the inner wall of fixed plate 501 There is cushion block 502, and the interior welds of fixed plate 501 are connected with reinforcing rib 503, cushion block 502 is rubber material, reinforcing rib 503 Be equally distributed in the inside of fixed plate 501, by cushion block 502 can make injection rod and injection plunger with second couple axis body 5 it Between connect even closer, while under the action of reinforcing rib 503, intensity is more preferable when the second connection axis body 5 can be made to use.

Working principle: it when using the coupling spindle being connect for injection plunger with injection rod, according to Fig. 1-6, works first First connecting shaft body 1 is placed on corresponding position by personnel, and injection rod is then coupled axis body 5 with second and is attached, if second Spacing between spindle body 5 is less than the diameter of injection rod, and at this moment staff can first take out the gag lever post 8 in limit hole 7, Then knob 6 is turned clockwise, makes knob 6 that screw rod 2 be driven to rotate clockwise together, because of the screw thread rotation of the upper and lower ends of screw rod 2 To on the contrary, and screw rod 2 and connecting tube 3 are to be threadedly coupled, therefore can drive the same time shift of 2 connecting tubes 3 when screw rod 2 rotates It is dynamic, to make 2 connecting tubes 3 that fixed block 4 and second be driven to couple axis body 5 to the side far from 1 center line of the first connecting shaft body respectively To movement, in this way it is gradually increased just the spacing between the second connection axis body 5；

When the spacing between the second connection axis body 5 is greater than the diameter of injection rod, injection rod is inserted into second by staff Couple in the gap between axis body 5, then turn knob 6 counterclockwise, according to above-mentioned principle, 2 second connection axis bodies 5 can together It is mobile to the direction of 1 center line of the first connecting shaft body, it gradually fits with injection rod, wherein the cushion block 502 of rubber material can make to press The even closer of bar fitting is penetrated, and the reinforcing rib 503 inside fixed plate 501 can make the second connection axis body 5 firmer, increase The fastness when coupling spindle uses, after knob 6 turns to certain angle, gag lever post 8 is inserted into limit hole 7 by staff In, knob 6 is fixed, it is ensured that the stability when coupling spindle uses, is the course of work of whole device above, and this The content being not described in detail in specification belongs to the prior art well known to professional and technical personnel in the field.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
