Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
As shown in Figs. 1-2, a kind of infusion connector of the utility model, including connector 1, outer tube 2, active pointer block up 3, nut cap 4
With pad pasting 5.
As shown in figure 3, connector 1 includes nut cap room 11, middle chamber 12 and junction block 13, nut cap room 11 and junction block 13 are arranged
Both ends and integrated molding in middle chamber 12, nut cap room 11 and 12 junction of middle chamber have the stair-stepping first prominent inner edge
111, one end that middle chamber 12 is provided with junction block 13 is provided with tapering 121, and internal diameter is gradually reduced from inside to outside, in nut cap room 11
It is inside provided with the first card slot 112, the second card slot 122 is provided in middle chamber 12.
As shown in figure 4, active pointer stifled 3 includes perfusion tube 31 and infusion hole 32, the setting closed at one end of perfusion tube 31, defeated
Infusion hole 32 is set on the side wall of liquid pipe 31, penetrates through the other end of infusion hole 32 and perfusion tube 31, infusion hole 32 is at least arranged
One.Perfusion tube 31 has the stair-stepping second prominent outer rim 33, in order to be more secure, snap ring 34 can also be arranged.Perfusion tube
Third card slot 35 is also provided on 21.
As shown in figure 5,2 inner wall of outer tube is provided with the second prominent inner edge 24 to match with the second prominent outer rim 33, may be used also
To be provided with the prominent inner edge 25 of the third to match with snap ring 34.The inner circumferential of outer tube 2 is provided with the first convex clip circle 23, on outer wall
Second convex clip circle 22 is set, and the outside of outer tube 2 is provided with the stair-stepping first prominent outer rim 21.
As shown in fig. 6, nut cap 4 is cylindrical shape, the top of nut cap 4 is closed to be arranged and is provided with nut cap tapering 41, in addition,
Retainer ring 42 is set in the inside of nut cap 4, third convex clip circle 43 is provided on the outer wall of nut cap 4.
As Figure 7-9, a kind of infusion connector of the utility model, including connector 1, outer tube 2, active pointer block up 3, nut cap 4
With the matching relationship of pad pasting 5:
Active pointer stifled 3 is arranged in outer tube 2, and the outer wall of active pointer stifled 3 is bonded setting with the inner wall of outer tube 2, reaches
The closed purpose of infusion hole 32；When plastics needle tubing is inserted into stifled 3 pipe of active pointer, it can be moved along 2 inner wall of outer tube since active pointer blocks up 3
Dynamic, plastics needle tubing can not be firmly inserted into active pointer stifled 3 at this time, and the of the prominent outer rim 33 of the second of perfusion tube 31 and outer tube 2
The two prominent matching of inner edge 24 settings, one resistance makes more firm between plastics needle tubing and perfusion tube 31 when giving the insertion of plastics needle tubing
Gu while preventing stifled 3 displacement of active pointer from be detached from it with outer tube 2；In order to further reach protection effect, it is additionally provided with
Pull ring 34 and the prominent inner edge 25 of third.First convex clip circle 23 of outer tube 2 is matched with the third card slot 35 on active pointer stifled 2.Cause
This, when in use, as shown in figure 9, active pointer blocks up 3 thrust by plastics needle tubing, third card slot 35 is moved to the first convex clip circle
At 23, the first convex clip circle 23 is fallen into third card slot 35, is that active pointer stifled 3 is fixed and opposing stationary with outer tube 2, in this way can be with
It prevents active pointer stifled 3 movable in outer tube 2, so that accident occur, while playing the role of being again sealed off, prevent liquid from active pointer
Stifled 3 with flowed out in the gap of outer tube 2.
Outer tube 2 is arranged in connector 1, sets in the second convex clip circle 22 and the middle chamber 12 of connector 1 being arranged on 2 outer wall of outer tube
The second card slot 122 set matches, and the second convex clip circle 22 can be firmly stuck in the second card slot 122, while playing sealing and making
With preventing liquid in junction block 13 from flowing out by the gap between outer tube 2 and connector 1.In addition, in order to preferably make outer tube 2
It is arranged in connector 1, the first prominent outer rim 21 is matched with the first prominent inner edge 111, not only plays position-limiting action in this way, but also make
The fixation of outer tube 2 is more stable.The setting in tapering 121 plays position-limiting action to outer tube 2.
Nut cap 4 is arranged in the nut cap room 11 of connector 1, and the outer wall of nut cap 4 is arranged between connector 1 and outer tube 2 and pastes
Setting is closed, in order to increase the fastness that nut cap 4 is connect with connector 1, the third convex clip circle of the first card slot 112 and nut cap 4 of connector 1
43 match；In addition, retainer ring 42 in nut cap 4 is contacted with active pointer stifled 3,3 limits are blocked up to active pointer, do not make it in transit not
It can be subjected to displacement because of external force, cause unnecessary damage.Nut cap tapering 41 is set on the top of nut cap 4, can be made in this way
Pad pasting 5 is easy to remove when in use, in addition, the setting in nut cap tapering 41 reduces the thickness at top, is easy to stab plastics needle tubing
It is broken.
In one embodiment, outer tube 2 is made of polypropylene material, and pad pasting 5 is aluminium foil or plastic adhesive film or the pad pasting
5 be transparent, silver color or golden composite membrane.
As shown in figure 8, state when a kind of infusion connector of the utility model is not used are as follows: active pointer stifled 3 has infusion
Hole 32 is in the fitting of outer tube 2, and liquid can not flow into perfusion tube 31 from infusion hole 32, to achieve the effect that sealing；Continue to join
According to shown in Fig. 9, for the state diagram after using, active pointer stifled 3 is moved along outer tube 2, and infusion hole 32 leaves outer tube 2, makes infusion hole 32
It is exposed in middle chamber 13, therefore, liquid can be flowed between junction block 13 and perfusion tube 31 by infusion hole 32.
The above is only the preferred embodiments of the utility model, are not used to limit the scope of the utility model；If
The spirit and scope for not departing from the utility model, are modified or replaced equivalently the utility model, should all cover in this reality
In novel scope of protection of the claims.
