Detailed description of the invention

By preferred embodiment effect that architectural feature of the present utility model and expection thereof are reached will be described below, but non-use To limit the claimed category of this utility model, conjunction is first chatted bright.

Refer to Fig. 1 to 9, it shows a preferred embodiment of the present utility model, and protecting cover 1 of the present utility model is for detachable Be installed in a syringe 9, this syringe 9 includes a needle section 91, and this protecting cover 1 includes fastener 2 and a cover piece 3.

This fastener 2 is provided with at least one clamping part 23, and this clamping part 23 has one for being radially snapped in this needle section 91 Breach 241.

This cover piece 3 is pivotally located at this fastener 2, connects the side of this accommodation space 32 including an accommodation space 32, To opening 34, this cover piece 3 can make a needle body 92 of this needle section 91 via this lateral openings towards the direction pivot pendulum of this needle section 91 34 pivots are put to this accommodation space 32.During practical operation, after this syringe 9 is injected or has been drawn blood, can be by this cover piece 3 towards this The direction pivot pendulum of needle body 92, to be accommodated in this accommodation space 32 interior (as shown in Figure 6 to 7), it is to avoid this needle body by this needle body 92 92 expose and stab personnel.

It is preferred that the two side one at least within of this accommodation space 32 this lateral openings 34 adjacent is provided with at least one hook sheet 33, the two side of this accommodation space 32 this lateral openings 34 adjacent is respectively equipped with this hook sheet 33, respectively this hook in the present embodiment Sheet 33, for this needle body 92 is limited in this accommodation space 32 interior (as shown in Figure 8), houses to prevent this needle body 92 from departing from this once again Space 32.

Wherein, respectively this clamping part 23 is a c-type clasp 24 and has a breach 241, the shape of the inwall of this c-type clasp 24 Size supplies to buckle via this c-type corresponding to a pin base 93 or a connection piece 94, this pin base 93 or this connector 94 of this needle section 91 The breach 241 of ring 24 embeds this c-type clasp 24, and this fastener 2 is provided with two these clamping parts 23 at intervals in the present embodiment And the linkage section 27 being connected between these two clamping parts 23, these two clamping parts 23 are respectively for being snapped in this pin base 93 and should Connector 94, between these two clamping parts 23 formed this linkage section 27 adjacent spacer 28, these two clamping parts 23 and should Linkage section 27 with radial direction see general in ㄈ font, wherein this pin base 93 one end is separately radially provided with a flange 931, this flange 931 for being located in this spacer 28 (as shown in Fig. 4 to Fig. 5), firmly this pin base 93 is fixed on this connector 94, it is to avoid This pin base 93 arbitrarily departs from this connector 94 and departs from this fastener 2, it is worth mentioning at this point that, owing to this fastener 2 is provided with between this Compartment 28, therefore this fastener 2 is available for being suitable for the pin base 93 being located in different size size, it is to avoid this pin base 93 arbitrarily departs from should Connector 94 and depart from this fastener 2.It will be appreciated that needle section is not provided with connector and only one is somebody's turn to do in other embodiments Clamping part 23 is snapped in this pin base 93 also without can not.

It addition, this c-type clasp 24 is separately respectively equipped with the extension 242 of an arc adjacent to the two ends of this breach 241, these two Extension 242 is located remotely from each other, when this c-type clasp 24 is intended to this pin base 93 of buckle and this connector 94, and pin base 93 and this connector 94 can block the medial wall propping up these two extensions 242 to be bent outwards these two extensions 242, can make this pin base 93 and should Connector 94 is easier to buckle in this c-type clasp 24, and when being intended to dismantle this protecting cover 1, available finger is by these two extensions 242 Push aside outwardly, can be easier to separate this pin base 93 and two c-type clasps 24 of this connector 94 and this.Specifically, each this c-type Clasp 24 is separately provided with one the most inwardly and is butted on this pin base 93 or the protuberance of this connector 94 for card adjacent to the two ends of this breach 241 243, this c-type clasp 24 is general in Ω font.

Preferably this fastener 2 and this cover piece 3 are mutually to put one-body molded by pivot.Specifically, in the present embodiment Be additionally provided with one between this fastener 2 with this cover piece 3 and flexible be connected sheet 4, this flexible connection sheet 4 be integrally connected to this cover piece 3 with should Fastener 2, so that this cover piece 3 can mutually be put by pivot with this fastener 2.

Wherein, the two ends of this fastener 2 are transversely provided with two male members 25, and these two male members 25 are respectively equipped with one face to face Card convex 251, this cover piece 3 is respectively provided on two sides with single order portion 35, when this cover piece 3 is towards away from this pin adjacent to one end of this fastener 2 The direction pivot pendulum of head 91 and this cover piece 3 are with this fastener 2 in when being mutually perpendicular to, and respectively this card convex 251 is mutually blocked with this rank portion 35 Supporting and interfere (as shown in Fig. 1, Fig. 3 and Fig. 9), this cover piece 3 i.e. cannot be put with this any phase pivot of fastener 2, to avoid when injection This cover piece 3 is put with this any phase pivot of fastener 2 and is disturbed injection process.Specifically, respectively this male member 25 is ㄥ shape, this fastener 2 are additionally provided with two profile grooves 26, and these two profile grooves 26 are respectively arranged between this two card convexs 251 and this cover piece 3.

This utility model separately provides a kind of syringe 9, and this syringe 9 includes protecting cover 1 as above, and this syringe 9 is another Including cylinder 95, pin base 93 and a needle body 92.This cylinder 95 encloses structure and goes out a room 96, and this room supplies to contain an injection, This pin base 93 is connected to this cylinder 95, and this needle body 92 is located at this pin base 93 one end away from this cylinder 95, in the present embodiment should Cylinder 95 is additionally provided with a connection piece 94, and this pin base 93 is connected to this connector 94 of this cylinder 95.When this syringe 9 is injected or taken out After blood is complete, can keep away by this cover piece 3 towards the direction pivot pendulum of this needle body 92 so that this needle body 92 is accommodated in this accommodation space 32 Exempt from this needle body 92 to expose and stab personnel.

To sum up, this utility model protecting cover and include the syringe of this protecting cover, after the injection of this syringe or having drawn blood, This cover piece is put, to be accommodated in this accommodation space by this needle body, it is to avoid this needle body exposes and stabs towards the direction pivot of this needle body Personnel.

When this cover piece towards away from the direction pivot pendulum of this needle section and this cover piece and this fastener in when being mutually perpendicular to, respectively this card Convex and this rank portion mutually fastens interference, and this cover piece i.e. cannot be put by phase pivot any with this fastener, to avoid this cover piece in time injecting Phase pivot any with this fastener is put and is disturbed injection process.
