The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
Referring to figures 1-3 of the drawings, the utility model provides a technical scheme that: an insulin injection needle cap capable of preventing puncture injury comprises a needle cap body 1 and a rotating frame 6, wherein the needle cap body 1 is sleeved outside an injection needle body 2; the injection needle body 2 is arranged on the needle cover 4, a supporting table 3 in a round table shape is arranged on the upper side of the needle cover 4, and the injection needle body 2 is arranged on the supporting table 3; the side surface of the bearing table 3 is provided with a rotating seat 5, one end of the rotating frame 6 is fixedly connected with the needle cap body 1, and the other end of the rotating frame 6 is connected with the rotating seat 5 through a rotating shaft 7; the whole bar-shaped structure that is of needle cap body 1, open at needle cap body 1 side has accomodate groove 10, injection needle body 2 card is in accomodate groove 10.
Further, the rotating frame 6 is composed of two sections of straight structures which are inclined with each other, and the connecting part is an arc-shaped transition section; the included angle between the two sections of straight structures is the same as the included angle between the upper surface and the side surface of the bearing table 3, and the straight structures are mutually perpendicular to the needle cap body 1.
Further, a clamping block 11 is arranged at the inner side of the accommodating groove 10, the clamping blocks 11 are symmetrically arranged on the groove wall at one side of the accommodating groove 10, and a gap is reserved between the groove wall of the other side of the containing groove 10; the whole fixture block 11 is L-shaped structure, and a clamping groove is formed between the fixture block 11 and the groove wall of the containing groove 10.
Further, one end of the clamping block 11 is arranged to be of a semicircular structure, and the other end of the clamping block is connected with the groove wall of the containing groove 10 through an arc-shaped structure.
Further, a coil spring is arranged in the rotating frame 6, the coil spring is sleeved outside the rotating shaft 7, two ends of the coil spring are respectively connected with the rotating frame 6 and the rotating seat 5.
Further, the top end of the needle cap body 1 is provided with a chamfer structure 9, the chamfer structure 9 is a quarter arc; the needle cover 4 is uniformly provided with strip-shaped friction lines 8.
Working principle: in the actual use process, the needle cap body 1 and the needle cover 4 are of an integrated structure, the needle cap body 1 is installed on the rotating seat 5 through the rotating frame 6 on the side face by using the rotating shaft 7, and the needle cap body 1 can rotate, so that the needle cap body 2 can rotate upwards or downwards, and the purpose of shielding the needle body is achieved.
The outside of the rotating shaft 7 is sleeved with a coil spring, two ends of the coil spring are respectively connected with the rotating frame 6 and the rotating seat 5, and the coil spring provides elasticity to enable the needle cap body 1 to be far away from the injection needle body 2 under the action of no external force, so that the needle cap can not cause obstruction to the injection process when the needle cap is taken down to use the needle body for injection.
When the needle cap body 1 is sleeved outside the injection needle body 2, the injection needle body 2 is clamped in the accommodating groove 10, the injection needle body 2 passes through a gap between the clamping block 11 and the groove wall, and then is clamped in a clamping groove between the clamping block 11 and the groove wall of the accommodating groove 10; the needle cap body 1 always has a trend of outward movement under the action of the coil spring, so that the clamping block 11 and the clamping groove are further clamped, and the stability of the needle cap body 1 after clamping is ensured. When the needle cap body 1 needs to be taken down, the needle cap body 1 is pressed in the opposite direction of the elasticity of the coil spring, so that the injection needle body 2 falls off from the clamping groove, then the side face enables the needle cap body 1 to deviate, the injection needle body 2 penetrates out of a gap between the clamping block 11 and the groove wall, and the needle cap body 1 is taken down. One end of the clamping block 11 is arranged into a semicircular structure, so that the injection needle body 2 can be conveniently clamped into the clamping groove or the clamping gap.
