This utility model is set to further, is set to plane bottom relative second chute of described fixed block.
By adopting such scheme, arranging bottom relative second chute of fixed block and being set to plane, fixture block dorsad needle guard is also plane by mouth end face, by the mutual conflict between two planes, makes to be fixedly connected with between fixture block with fixed block, is not easy to be separated.
This utility model is set to further, is provided with the first slug in described first chute, and described needle guard outer surface is provided with the second slug, and described first slug and described second slug match.
By adopting such scheme, when mounted in order to avoid makeing mistakes, first slug is set and the second slug is made mistakes to avoid operative, after medical personnel used syringe needle, to fasten when making first slug misalignment the second slug that just can to realize between needle stand and needle guard locked as long as rotate.
This utility model is set to further, is at least provided with two limited blocks in described first chute, is at least provided with two fixed blocks in described second chute, is at least provided with two fixture blocks in described needle guard.
By adopting such scheme, be respectively arranged with two limited blocks, two fixed blocks and two fixture blocks, arranging multiple is to make location and locked better effects if, even and if have limited block, fixed block or a fixture block to come off still can to realize and to locate and locked.
This utility model is set to further, and described inclined-plane is set to circular arc.
Compared with prior art, the utility model has the advantage of: this utility model is by limited block, cooperatively interacting between fixed block and fixture block, make mutual clamping between limited block and fixture block when mounted, the fit that can realize needle stand and needle guard be separated, realize locked by coordinating between fixed block with fixture block after use, and the needle stand after preventing from using is separated with needle guard and stab medical care, cleanup crew.

Detailed description of the invention
With reference to accompanying drawing, this utility model self-locking injection syringe syringe needle embodiment is described in further details.
In the present embodiment, a kind of self-locking injection syringe syringe needle 2, comprise needle stand 3, syringe needle 2, needle guard 1, described needle stand 3 outer surface is provided with the first chute 9 and the second chute 10, two limited blocks 4 are provided with in described first chute 9, the bottom of relative first chute 9 of described limited block 4 is set to inclined-plane, two fixture blocks 5 are provided with in described needle guard 1, the opening of the relative needle guard 1 of described fixture block 5 is set to arc surface, the slippage of described fixture block 5 is connected in the first chute 9, described needle guard 1 is by fixture block 5 and limited block 4 clamping, two fixed blocks 6 are provided with in described second chute 10, plane is set to bottom relative second chute 10 of described fixed block 6, described fixture block 5 is connected with the second chute 10 slippage, described needle guard 1 is fixedly connected with fixed block 6 by fixture block 5, the first slug 7 is provided with in described first groove, described needle guard 1 outer surface is provided with the second slug 8, described first slug 7 matches with described second slug 8.
According to said structure, when needle guard 1 is arranged on needle stand 3, identified by the first slug 7 and the second slug 8, fixture block 5 slippage when corresponding installation connects into the first chute 9, the limited block 4 that first chute 9 is arranged, the lower surface of fixture block 5 is arc surface, by arc surface along limited block 4 surface sliding to the below of limited block 4, and be inclined-plane bottom relative first chute 9 of limited block 4, fixture block 5 on needle guard 1 is by the slippage with limited block 4 bottom bevel, make the mutual clamping between fixture block 5 and limited block 4, to realize the location between needle stand 3 and needle guard 1, also needle stand 3 and needle guard 1 is made to be separated from each other, after use, rotate needle guard 1 makes the second slug 8 be positioned at the other end of the first slug 7, now fixture block 5 slippage is entered in the second chute 10, fixed block 6 in second chute 10 cooperatively interacts with fixture block 5, the lower surface of fixture block 5 is arc surfaces, conflict fixed block 6 is all the upper surface of circular arc, make fixture block 5 slippage to the below of fixed block 6, the lower surface of fixed block 6 is upper surfaces of plane and fixture block 5 is plane, cooperatively interact and achieve a fixed connection, make between needle stand 3 and needle guard 1 locked.
Pass through such scheme, first slug 7 is set and the second slug 8 prevents workman from occurring mistake in installation, also can make medical personnel after using syringe, make needle guard 1 and needle stand 3 locked simultaneously, two limited blocks 4 on first chute 9, fixture block 5 on needle guard 1 matches, arrange two each and every one limited blocks 4 further to limit with fixture block 5, can prevent from separating easily between needle stand 3 with needle guard 1, and by limited block 4 and fixture block 5, needle stand 3 can be installed also can be separated with needle guard 1, after use, make fixture block 5 slippage enter the second chute 10, fixed block 6 on second chute 10 cooperatively interacts with the fixture block 5 on needle guard 1, plane bottom plane second chute 10 relative to fixture block 5 of fixture block 5 needle guard 1 opening dorsad matches, make between needle stand 3 and needle guard 1 locked, make needle stand 3 and needle guard 1 locked inseparable, illegal molecule so just can be prevented the recycling of syringe needle 2 main body, avoid used needle stand 3 to be separated with needle guard 1 stabbing medical personnel or street cleaner that blood occurs to infect simultaneously, and make disposable syringe syringe needle 2 main body use more safe and sanitary.
This city is preferably with novel, described fixture block 5 relatively needle guard 1 opening is set to circular arc, opening is set to plane dorsad, described limited block 4 is arranged to triangular prism shaped, upper and lower two surfaces are all set to inclined-plane, reduce the movement travel of fixture block 5, and reduce friction, make fixture block 5 convenient with coordinating of limited block 4, also the dismounting of needle guard 1 and needle stand 3 is facilitated, the end face of the opening of relative second chute 10 of described fixed block 6 is set to circular arc, make fixed block 6 and fixture block 5 in the convenience loading more frame, plane is set to bottom relative second chute 10 of fixed block 6 opening, and relative needle guard 1 opening of fixture block 5 is also plane, make fixture block 5 and fixed block 6 inconsistent and be not easy to separate by plane.
Below be only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under this utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under this utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
