It wherein is provided with host cavity 30 in the deck 3, the needle stand 2 is arranged on the top of 3 host cavity 30 of the deck,
The safety protective cover 5 is arranged in the lower part of 3 host cavity 30 of the deck, and part is revealed in outside the deck 3.The spring
4 are arranged between the needle stand 2 and safety protective cover 5.The needle tubing 6 is arranged in the needle stand 2, and extends downwardly through institute
Safety protective cover 5 is stated, end needle point is revealed in outside the safety protective cover 5.The needle stand protective case 1 is set in the deck
3 outside, and simultaneously by the needle tubing 2 also it is completely obscured in the inner.
Further, it please refers to shown in Fig. 2, wherein being provided with the guide groove 31 extended up and down, the guide groove on the deck 3
It is provided in 31 and is oriented to shrapnel 33, and the lower part of the part guide groove 31 is divided by left part guide groove 311 as boundary using it and right part is led
312 two parts of slot, wherein the bottom surface 314 of the right part guide groove 312 is higher than the bottom surface 313 of the left part guide groove 311.Moreover, institute
It is to be arranged obliquely in the guide groove 31 to state and be oriented to shrapnel 33, partly to cover the upper opening of the right part guide groove 312.When
So, can also be all to cover the right side in different embodiments since the guiding shrapnel 33 has certain elasticity
The upper opening of portion's guide groove 312, but be not limited to.
Flexible barbs 35 are additionally provided in the left part guide groove 311, are extended under in the left part guide groove 311,
And the left part guide groove 311 is substantially divided into two parts.The wherein described flexible barbs 35 can also be to extend to set obliquely
It sets, either, as shown in the figure, the guiding surface 351 of setting one diagonally downward, but be not limited to.
Fixed pin 52 is provided on the safety protective cover 5, initial stage is housed in the right part guide groove 312, and passes through
Its bottom surface 314 limits, and then to realize the limit of the deck 3 relatively of the safety protective cover 5.At this point, the medical injection
The safety protective cover 5 of device is in the initial position under unused state, and the needle point of 6 end of needle tubing is by the needle stand protective case
1 is covered, to avoid its exposed.
In use, removing the needle stand protective case 1 so that the needle point of the needle tubing 6 is pierced into the skin in precalculated position.When
When pushing 6 needle point of the needle tubing and carrying out stretching into injection, the safety protective cover 5 can be under the opposition of skin, to moving up
It is dynamic, while can also compress the compression of the spring 4.At this moment, the fixed pin 52 of the safety protective cover 5 is along the right part guide groove 312
When upwards, by the guiding shrapnel 33, applying upward power to it so that the guiding shrapnel 33 bounces on outward, from
And concede space and make the fixed pin 52 by entering the top of the guide groove 31, it is described after the fixed pin 52 passes through
Shrapnel 33 is oriented to set back.At this moment, the safety protective cover 5 of the injector for medical purpose is in the operating position under use state,
It is specifically illustrating, please refers to shown in Fig. 3.
After the completion of injection, the needle tubing 6 is extracted out of skin, at this moment, the external force removal that the safety protective cover 5 is subject to,
It is moved under the action of the compression reaction power of the spring 4, and at this moment the fixed pin 52 of the safety protective cover 5 is along the guide groove
31 move down.In moving process, the guiding shrapnel 33 can be encountered, due to it is described be oriented to shrapnel 33 be obliquely installed and
It being blocked to what is be open on the right part guide groove 312 so that it can guide the fixed pin 52 to slide to left part guide groove 311, rather than
It is downwardly into right part guide groove 312, is specifically illustrating, is please referred to shown in Fig. 4.
After the fixed pin 52 enters the left part guide groove 311, please refer to shown in Fig. 5, the fixed pin 52 is downward
In sliding process, the flexible barbs 35 can be encountered, it is described solid under the action of the downward elastic restoring force of the spring 4
Rationed marketing 52 can push down on the flexible barbs 35 and outwardly open.Due to the contact surface of the flexible barbs 35 and the fixed pin
For guiding surface 352, so that the flexible barbs 35 by slanting power, as shown by arrows in figure, make it downwardly toward outer
It opens more convenient, while also opening the space for leading to 311 bottom surface 313 of left part guide groove.The fixed pin 52 continues to move to, directly
Stop to being limited by 311 bottom surface 313 of the left part guide groove.At this moment, the safety protective cover 5 of the injector for medical purpose is in and has used
Final position after, while also the end of needle tubing 6 is stated in completely obscured residence to the safety protective cover 5, is specifically illustrating, is please referred to
Shown in Fig. 6.
Further, it if thinking that the safety protective cover 5 is reversely pushed to be restored to operating position, please refers to shown in Fig. 7, at this moment
5 stress of the safety protective cover is upward, and fixed pin 52 upwards can be by the blocking of the flexible barbs 35, between the two can phase
Mutually contradict, because the flexible barbs 35 are as shown by arrows in figure, therefore, only it to be made to be unfolded upwards by upward power,
And then close the Upwards channel of the left part guide groove 311.In this way, the fixed pin 52 also can not just continue up, even if
Increase external force, also can only be to destroy its own structure.To can effectively avoid it by wrongful recycling, and made by secondary
With.
Further, for the guiding shrapnel 33, between flexible barbs 35 and the fixed pin 52 it is unidirectional by, it is anti-
It, in different embodiments, can be there are many structure be changed, in the creation of the utility model to the frame mode against conflict
Under spirit, be regarded as be the utility model disclose structure equivalent variations.
Further, it for the setting of the spring 4, might not be necessary, can also be made by outer force effect
The spring 4 is arranged by the blocking of the flexible barbs 35 in the fixed pin 52 of the safety protective cover 5, only so that operation
It is more easy.
The utility model is related to a kind of injector for medical purpose, use brand-new design safeguard protection nested structure and and its
The cartridge structure of mating so that upon completion of the injection, the safety protective cover can stretch out the deck to the syringe, and to needle
The end of pipe carry out it is completely obscured, so as to avoid because after the completion of use, the syringe tip needle point it is exposed may caused by
Safety problem.
Further, the docked mode between the safety protective cover and the deck, but also the safety protective cover
It after stretching out the deck, cannot be again retracted into the deck in the case where not destroying its structure, so that the doctor
After use with syringe, can only be destroyed, it cannot simply be recycled and reused, to effectively avoid because it is not by
Correctly recycling is reused, and malpractice caused by possibility.
The technical scope of the utility model is not limited solely to the content in above description, and those skilled in the art can be
Under the premise of not departing from the utility model technological thought, to above-described embodiment carry out many variations and modifications, and these deformation and
Modification should all belong in the scope of the utility model.
