Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0018] Example: A syringe cap removal box, such as Figures 1-4 As shown, it includes a syringe 001, a needle cap 002, a base plate 1, a housing 2, a pushing assembly, and a clamping mechanism. The housing 2 is fixed to the top of the base plate 1 by bolts. The pushing assembly is provided on the top of the housing 2. The syringe 001 is placed on the pushing assembly. The needle cap 002 is provided at the bottom of the syringe 001. The clamping mechanism for clamping the needle cap 002 is provided inside the housing 2. The pushing assembly is used to push the clamping mechanism to complete the clamping action.

[0019] like Figure 1 and Figure 2 As shown, the pushing assembly includes a U-shaped sliding plate 31, a compression spring 32, and a trapezoidal push block 33. The U-shaped sliding plate 31 is slidably disposed on the top of the outer shell 2. Two compression springs 32 are connected between the U-shaped sliding plate 31 and the outer shell 2. The trapezoidal push block 33 is fixedly welded to the lower part of the U-shaped sliding plate 31 in a mirror-like manner. A U-shaped opening 21 is opened in the middle of the U-shaped sliding plate 31. The syringe 001 is placed at the U-shaped opening 21. A V-shaped opening 22 is opened on the front side of the top of the outer shell 2. The setting of the V-shaped opening 22 makes it convenient for medical staff to observe the needle cap 002.

[0020] like Figure 2 and Figure 3 As shown, the clamping mechanism includes a slide rail 41, a slider 42, a tension spring 43, a U-shaped mounting plate 44, a rotating shaft 45, a rubber roller 46, a trapezoidal limiting block 47, and a limiting component. Slide rails 41 are welded and fixed to the inner walls of the front and rear panels of the outer shell 2. Two sliders 42 are slidably connected to each slide rail 41. Tension springs 43 are connected between each slider 42 and the adjacent inner wall of the outer shell 2. U-shaped mounting plates 44 are welded and fixed between each adjacent slider 42. Rubber rollers 46 are rotatably connected to each U-shaped mounting plate 44. Trapezoidal limiting blocks 47 that cooperate with trapezoidal push blocks 33 are welded and fixed to the side walls of the two U-shaped mounting plates 44 that are far apart from each other. A limiting component is provided between the front end of the rotating shaft 45 and the adjacent U-shaped mounting plate 44. The limiting component is used to restrict the rubber roller 46 to rotate only in one direction.

[0021] like Figure 3 and Figure 4As shown, the limiting assembly includes a ratchet 51, a fixed shaft 52, a pawl 53, and a torsion spring 54. The front ends of the two U-shaped shafts 45 are fixedly connected to the ratchet 51, and the front sides of the two U-shaped mounting plates 44 are fixedly connected to the fixed shafts 52. Pawls 53 are rotatably connected to the two fixed shafts 52. Torsion springs 54 are connected between the two pawls 53 and the adjacent U-shaped mounting plates 44. The two pawls 53 can engage with the adjacent ratchet 51. With the cooperation of the pawls 53, torsion springs 54, and ratchet 51, the two rubber rollers 46 can only rotate inward in one direction. The pawls 53 and ratchet 51 are existing technologies, so their working principle will not be described in detail.

[0022] In use, medical personnel first hold syringe 001 and pass the needle cap 002 at the end of syringe 001 through the U-shaped opening 21 and the V-shaped opening 22 in sequence until the bottom of syringe 001 contacts the U-shaped sliding plate 31. Then, the medical personnel press syringe 001 downwards. This action pushes the U-shaped sliding plate 31 downwards, simultaneously compressing the two compression springs 32. As the U-shaped sliding plate 31 moves downwards, the two trapezoidal push blocks 33 also move downwards, squeezing the two trapezoidal limiting blocks 47, causing them to move closer to each other, thereby pushing the two U-shaped mounting plates 44 closer to each other. Simultaneously, the tension spring 43 is gradually stretched. At this time, the two rubber rollers 46 begin to clamp the needle cap 002. As the syringe 001 moves the needle cap 002 downward, due to the pawl 53 and ratchet 51, the two rubber rollers 46 can rotate inward. Thus, as the two rubber rollers 46 come into contact with and gradually clamp the needle cap 002, the syringe 001 can still continue to push the U-shaped sliding plate 31 downward, providing power for the two rubber rollers 46 to approach. When the two compression springs 32 are compressed to their limit, the medical staff then lifts the syringe 001 upward. Under the reset action of 32, the U-shaped sliding plate 31 moves upward and resets, and the trapezoidal push block 33 gradually releases its pressure on the trapezoidal limiting block 47. At this time, under the restriction of ratchet 51 and pawl 53, the two rubber rollers 46 cannot rotate outward. Therefore, there is a large clamping friction between the rubber rollers 46 and the needle cap 002. Under the action of this friction, the needle cap 002 separates from the syringe 001 and is clamped and fixed between the two rubber rollers 46. As the trapezoidal push block 33 completely separates from the trapezoidal limiting block 47, the two U-shaped mounting plates 44 move away from each other under the reset action of the tension spring 43. The needle cap 002 is moved to release the two rubber rollers 46 from their grip, and the needle cap 002 falls onto the base plate 1 under its own weight. Then, medical staff can remove the syringe 001 from the U-shaped opening 21 at an upward angle, while the needle at the bottom of the syringe 001 leaves the outer shell 2 from the V-shaped opening 22. This effectively avoids direct contact between the needle and the outer shell 2, thus preventing the needle from being contaminated. The entire process can be completed by one-handed operation to separate the needle cap 002, which is simple, efficient and reduces the risk of medical staff being pricked when manually removing the needle cap 002.

[0023] like Figure 1 and Figure 2 As shown, it also includes a collection box 6, which is slidably disposed on the lower side of the outer casing 2.

[0024] By setting up the collection box 6, the needle caps 002 that fall from the rubber roller 46 can be easily collected for subsequent processing.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
