DETAILED DESCRIPTION

[0030] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp. Embodiment 1:

[0031] A quantitative injection medical cosmetic needle comprises a needle head 1, a needle tube 2 and a piston push rod 3. A piston block 4 is arranged at one end of the piston push rod 3, and a piston handle 5 is arranged at the other end. Medical staff complete the injection by pushing the piston handle 5. The needle tube 2 is transparent and engraved with scales for marking the dosage of the medicine liquid. A clamping ring 6 is also sleeved on the outer side of the needle tube 2. The clamping ring 6 is slidably arranged on the outer tube wall of the needle tube 2. A cavity 7 is opened inside the clamping ring 6. A hoop lock 11 is arranged in the cavity 7. The hoop lock 11 is used to tighten the needle tube 2 and fix the clamping ring 6 at any position of the outer tube wall of the needle tube 2. A sliding hook ring 8 is arranged at the tail of the piston drag rod. The sliding hook ring 8 is slidably arranged on the outer tube wall of the needle tube 2. The sliding hook ring 8 is half-open. When the clamping ring 6 is locked in the set position, the sliding hook ring 8 presses against the clamping ring 6 and represents the set dosage of the medicine liquid that has been injected when the medicine liquid is pushed for injection.

[0032] The clamping ring 6 includes a cover plate 9 and a shell 10, and the cover plate 9 and the shell 10 are detachably connected by screws. The cover plate 9 and the shell 10 form a cavity 7. The clamping lock 11 includes a wall-pressing rubber 12, a pressure plate 13 and a stud. The wall-pressing rubber 12 and the pressure plate 13 are both arranged in the cavity 7. The wall-pressing rubber 12 is in an arc shape and fits with the outer wall of the needle tube 2. The stud includes a screw 14 and a column head 15. The column head 15 is exposed from the cover plate 9 and is provided with anti-slip grooves. The screw 14 is threadedly connected to the cover plate 9. The bottom of the screw 14 abuts against the pressure plate 13, and the pressure plate 13 abuts against the wall-pressing rubber 12. When the column head 15 is rotated, the screw 14 presses against the pressure plate 13 and compresses the wall-pressing rubber 12, thereby achieving a locking effect.

[0033] A plug 16 is provided at the top of the needle tube 2, a connecting hole 17 and a flange ring are provided at the tail of the needle 1, and an inclined guide rubber 19 is provided on the inner wall of the connecting hole 17. When the needle 1 is connected to the needle tube 2, the plug 16 compresses the inclined guide rubber 19. When the flange ring is in contact with the top surface of the needle tube 2, the needle 1 is stably fixed on the plug 16.

[0034] A pair of anti-slip rings 20 are also provided on the needle tube 2. When injecting, the fingers can be inserted into the anti-slip rings 20 to increase the force points. A side handle 21 is also connected between the piston push rod 3 and the sliding hook ring 8. The length of the side handle 21 is greater than the stroke length of the piston push rod 3. When the piston push rod 3 is fully pulled out, the sliding hook ring 8 is still stuck on the outside of the needle tube 2. The anti-slip ring 20 and the sliding hook ring 8 are staggered. When the sliding hook ring 8 slides to the connection between the anti-slip ring 20 and the needle tube 2, no interference will occur. Two through holes 22 are provided on the side handle 21. When the injection of liquid medicine is large, the distance between the piston handle 5 and the anti-slip ring 20 is large. By inserting the fingers into the through holes 22, the piston push rod 3 can also be pushed to move, thereby increasing the stability when injecting liquid medicine, and the requirement for the finger length of medical staff is relatively small.

[0035] A cross reinforcing rib 23 is provided on the piston push rod 3, and a rubber sealing block 24 is provided at the tail of the needle tube 2. A cross groove 25 is opened on the rubber sealing block 24. The cross groove 25 cooperates with the cross reinforcing rib 23 to seal, thereby increasing the sealing inside the needle tube 2 and reducing the possibility of dust and bacteria invasion. Embodiment 2:

[0036] The difference between the second embodiment and the first embodiment is that the hoop lock 11 includes a wall-pressing rubber 12, a hinged rod 26, a spring 27 and a pressure block 28. The hinged rod 26 is arranged in the clamping ring 6 and is hinged to the inner wall of the cavity 7. The wall-pressing rubber 12 is fixedly arranged at one end of the hinged rod 26 and faces the needle tube 2. The spring 27 is arranged on the same side of the hinged rod 26 that is away from the end of the wall-pressing rubber 12. The spring 27 drives the hinged rod 26 to rotate through elastic force and makes the wall-pressing rubber 12 press the outer tube wall of the needle tube 2. A pressure hole 29 is opened on the cover plate 9. The pressure hole 29 is arranged on the opposite side of the spring 27. A pressure block 28 is slidably arranged in the pressure hole 29. When the pressure block 28 is pressed down, it presses against the hinged rod 26 to compress the spring 27, so that one end of the wall-pressing rubber 12 rotates around the hinge point. At this time, the wall-pressing rubber 12 is separated from the outer tube wall of the needle tube 2, and the clamping ring 6 is unlocked from the needle tube 2, which is more convenient than using the screw 14 to lock and fix.

[0037] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
