The teeth 33, the plurality of second positioning teeth 34, and the plurality of third positioning teeth 35. A plurality of the first positioning teeth 33 are equally spaced apart from the front wall portion of the outer wall of the annular body 31, and a first spacing portion 32 is formed between the adjacent two first positioning teeth 33. A plurality of second positioning teeth 34 are equally spaced from the rear wall portion of the outer wall of the annular body 31, and a second spacing portion 37 is formed between the adjacent two second positioning teeth 34. The second positioning tooth 34 is opposite to the first spacing portion 32. The first positioning tooth 33 is opposite to the second spacing portion 37. A plurality of third positioning teeth 35 are equally spaced from the rear portion of the inner wall of the annular body 31.
該第一定位齒33是由一凸塊331連接一斜面塊335所構成，該斜面塊335的最高點連接於該凸塊331，該斜面塊的最低點連接於該環狀主體31外壁，並且相對於該第二間隔部37。 The first positioning tooth 33 is formed by a bump 331 connected to a bevel block 335. The highest point of the bevel block 335 is connected to the bump 331, and the lowest point of the bevel block is connected to the outer wall of the annular body 31, and Relative to the second spacer 37.
該第二定位齒34的結構厚度從其第一端341向第二端342漸減，該第二定位齒34的第一端341朝向該第一間隔部32。 The structural thickness of the second positioning tooth 34 gradually decreases from the first end 341 thereof to the second end 342, and the first end 341 of the second positioning tooth 34 faces the first spacing portion 32.
該第三定位齒35是由一凸塊351和一斜面塊355構成三角形結構，該斜面塊355的最高點連接於該凸塊351，該斜面塊355的最低點連接在該環狀主體31的內壁且接續於該環狀主體31之錐環面36的最小徑。 The third positioning tooth 35 is formed by a protrusion 351 and a slope block 355. The highest point of the slope block 355 is connected to the protrusion 351. The lowest point of the slope block 355 is connected to the annular body 31. The inner wall is connected to the smallest diameter of the tapered surface 36 of the annular body 31.
如第八、九、十一圖，該保護套50穿套於該注射筒11的外壁，之後再將鎖定環30穿套於該注射筒11之前端部14。該鎖定環30藉由該錐環面36以及第三定位齒35之斜面塊355之導引而順利通過該注射筒11之前端部14，直到該注射筒11之止擋緣15擋住該鎖定環30為止。基於鎖定環30所採用之塑料硬度大於該注射筒11之前端部14的塑料硬度，當該鎖定環30結合於該注射筒11前端部14時，該第三定位齒35的凸塊351是以強力壓迫並咬住該前端部14之外壁，使該鎖定環30定位於該注射筒11的前端部14。該鎖定環30之第一定位齒33的斜面塊335擋住該保護套50之推拔面52以及細肋 條53之前端的緣故，在沒有外力推動的情況下，該鎖定塊30擋住該保護套50，使保護套50不會輕易的在注射筒11上滑動或脫離注射筒11。 As shown in the eighth, ninth, and eleventh drawings, the protective cover 50 is sleeved on the outer wall of the syringe 11, and then the locking ring 30 is passed over the front end portion 14 of the syringe 11. The locking ring 30 passes through the front end portion 14 of the syringe 11 by the guiding of the tapered ring surface 36 and the inclined block 355 of the third positioning tooth 35 until the stopping edge 15 of the syringe 11 blocks the locking ring. 30 so far. The hardness of the plastic used in the locking ring 30 is greater than the plastic hardness of the front end portion 14 of the syringe 11. When the locking ring 30 is coupled to the front end portion 14 of the syringe 11, the protrusion 351 of the third positioning tooth 35 is The outer wall of the front end portion 14 is strongly pressed and bitten, and the lock ring 30 is positioned at the front end portion 14 of the syringe barrel 11. The bevel block 335 of the first positioning tooth 33 of the locking ring 30 blocks the push-out surface 52 of the protective cover 50 and the thin rib For the reason of the front end of the strip 53, the locking block 30 blocks the protective cover 50 without external force pushing, so that the protective cover 50 does not easily slide on the syringe 11 or disengage from the syringe 11.
如第八、十、十二圖，該保護套50後端內壁具有一止擋環54，該止擋環54具有一斜面541，該斜面541的最高點與該保護套50內壁連接形成一止擋邊542，該止擋邊542朝向該保護套50的後端。當注射針筒10使用後，該針體13必需被遮蔽以免戳扎醫護人員。此時，可以手指捏持該保護套50外壁，施力將該保護套50往該針體13的方向推動。基於該鎖定環30之第一定位齒33的斜面塊335擋住了該保護套50之推拔面52以及細肋條53之緣故，最初推動該保護套50時是會有些許阻力的，只要所施的推力突破該阻力，以及保護套50之塑膠料具有些微彈性之緣故，該保護套50之推拔面52和細肋條53可以通過該鎖定環30之第一定位齒33的斜面塊335，使得保護套50可以向針體13的方向移動；在推動該保護套50的過程中，該細肋條53通過該第一定位齒33的凸塊331表面時會產生磨擦力，因此可以稍微的限制該保護套50的移動的速度不致太快。而該凸緣51亦可發揮擋止手指的作用，避免推動保護套50時滑手。 As shown in the eighth, tenth, and twelfth drawings, the inner wall of the rear end of the protective cover 50 has a stop ring 54 having a slope 541. The highest point of the slope 541 is connected with the inner wall of the protective cover 50. A stop rib 542 faces the rear end of the protective cover 50. When the syringe 10 is used, the needle 13 must be shielded from punctuating the medical staff. At this time, the outer wall of the protective cover 50 can be pinched by a finger, and the protective cover 50 can be urged to push the direction of the needle body 13. The bevel block 335 of the first positioning tooth 33 of the locking ring 30 blocks the pushing surface 52 of the protective cover 50 and the thin rib 53 . When the protective cover 50 is initially pushed, there is a slight resistance, as long as it is applied. The thrust breaks through the resistance, and the plastic material of the protective cover 50 has a slight elasticity, and the pushing surface 52 and the thin rib 53 of the protective sleeve 50 can pass through the inclined block 335 of the first positioning tooth 33 of the locking ring 30, The protective cover 50 can be moved in the direction of the needle body 13; during the pushing of the protective cover 50, the thin rib 53 can generate a frictional force when passing through the surface of the protrusion 331 of the first positioning tooth 33, so that the slight limitation can be The movement of the protective cover 50 is not too fast. The flange 51 can also function as a finger stop to avoid slipping the hand when the cover 50 is pushed.
最終，當該保護套50完全遮蔽該針體13時，該保護套50後端內壁的止擋環54的斜面541通過該鎖定環30第二定位齒34，該止擋環54的止擋邊542與該第二定位齒34的第一端341相對抵制，以至於該保護套50無法再往後退移。除此之外，當該保護套50完全遮蔽該針體13時，該保護套50止擋環54的斜面541與該鎖定環30第一定位齒33之斜面塊335接觸，斜面相切對保護套50形成了大的阻力，該保護套50無法通過該第一定位齒33而脫離該鎖定環30。 Finally, when the protective cover 50 completely shields the needle body 13, the slope 541 of the stop ring 54 of the inner wall of the rear end of the protective sleeve 50 passes through the second positioning tooth 34 of the locking ring 30, and the stop of the stop ring 54 The edge 542 is relatively resistant to the first end 341 of the second positioning tooth 34, so that the protective cover 50 can no longer be retracted. In addition, when the protective cover 50 completely shields the needle body 13, the slope 541 of the retaining ring 50 of the protective sleeve 50 contacts the bevel block 335 of the first positioning tooth 33 of the locking ring 30, and the inclined surface is tangent to protect The sleeve 50 creates a large resistance that the boot 50 cannot escape from the locking ring 30 through the first positioning tooth 33.
