Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a sharps box. Background Art

[0002] In the field of medical supplies technology, a sharps box is a medical device used to safely collect and dispose of various sharps generated during the medical process. Existing sharps box designs usually adopt a split structure, consisting of a box body and a lid. The core concept of this design is that the box body and the lid are both integrally formed molded products. This manufacturing process ensures that there are no splicing interfaces in their respective structures. This feature is extremely important because medical sharps are often extremely sharp and penetrating. Any tiny gaps or splicing interfaces may become potential risk points for the exposure of sharps, which may cause medical staff or related personnel to suffer accidental injuries when handling sharps.

[0003] However, although this split sharps box has its unique features in terms of safety, it also has some shortcomings that cannot be ignored. First, since the box body and the lid are designed separately, when any one of the two components is missing, the sharps box cannot be used normally, which may cause great inconvenience in medical practice, especially in emergency situations. If the complete sharps box cannot be found in time, it will seriously affect the safe disposal of medical waste. Secondly, another potential problem with the split design is that during actual use, splicing errors may occur between the box body and the lid. This error may be caused by various factors, such as manufacturing tolerances, material deformation, or wear and tear after long-term use. The splicing error will not only cause the lid to fail to close normally, but may also cause medical staff to apply excessive force when trying to close the sharps box, which not only increases the difficulty and complexity of the operation, but may also cause additional safety risks due to improper operation. Therefore, a sharps box is proposed. Utility Model Content

Secondly, another potential problem with the split design is that in actual use, splicing errors may occur between the box body and the lid. This error may be caused by various factors, such as manufacturing tolerances, material deformation or wear after long-term use. The splicing error will not only cause the lid to fail to close normally, but may also cause medical staff to apply excessive force when trying to close the sharps box, which not only increases the difficulty and complexity of the operation, but may also cause additional safety risks due to improper operation. A sharps box is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sharps box comprises a box body, the top of the box body is fixedly connected to a rubber sheet, the rubber sheet is a flat-top pyramid and can be deformed, the inside of the rubber sheet is fixedly connected to the same top plate, the top center of the top plate is fixedly connected to an installation box, the inner walls on both sides of the installation box are rotatably connected to the same rotating shaft 1, the two ends of the circumferential outer wall of the rotating shaft 1 are fixedly connected to the same handle, the circumferential outer wall of the rotating shaft 1 is provided with an unlocking mechanism, the unlocking mechanism is used to unlock the fixed state of the top plate when the top plate is recessed in the box body and fixed.

[0007] In a possible design, the unlocking mechanism includes a driving gear and two mounting blocks, the driving gear is fixedly connected to the circumferential outer wall of the rotating shaft 1, the two mounting blocks are fixedly connected to the bottom of the top plate, and the two mounting blocks are rotatably connected to the same rotating shaft 2 on one side close to each other, and the rotating shaft 2 rotates through the mounting blocks at both ends, and a driven gear is fixedly connected to the center of the circumferential outer wall of the rotating shaft 2, and the driven gear is meshed with the driving gear. A fixing mechanism is provided at both ends of the rotating shaft 2, and the fixing mechanism is used to fix the top plate when the top plate is recessed into the box body.

[0008] In one possible design, the fixing mechanism includes a slide rail 1 and a slide rail 2, and the slide rail 1 and the slide rail 2 are both fixedly connected to the bottom side of the top plate, one end of the rotating shaft 2 rotates and passes through one side of the slide rail 1, and the inner walls on both sides of the slide rail 2 are slidably connected to two symmetrical clips, and the inner walls on both sides of the slide rail 1 are slidably connected to the same slider, and one side of the clip is slidably connected to a pin, and the pin slides through one side of the clip, and the ends of the two pins away from each other are fixedly connected to a baffle for preventing the pin from escaping from the clip, and the circumferential outer walls of the two pins are rotatably connected to the bottom of the slider through a pin shaft. The two clips are fixedly connected to the same spring on the sides close to each other.

[0009] In one possible design, both ends of the second rotating shaft are fixedly connected with a screw rod, the two screw rods rotate in opposite directions, the screw rod threads pass through the corresponding sliders, and a through groove is opened at the top center of the top plate, and the through groove is used to allow the driving gear and the driven gear to engage with each other.

[0010] In a possible design, the inner walls on the four sides of the box body are fixedly connected with a hollow shielding plate for double shielding to ensure that sharp objects do not leak out.

This design not only improves the overall structural strength of the sharps box, but also effectively prevents splicing errors that may occur during use of the sharps box, thereby ensuring that the lid can be closed normally and tightly, greatly reducing the safety risks caused by improper operation.

[0014] In the present invention, the sharps box, through the setting of the fixing mechanism and the unlocking mechanism, can use the rotating handle to drive the driving gear to rotate, and then drive the driven gear and the rotating shaft to rotate, and finally realize the unlocking and fixing of the buckle. This design not only simplifies the operation steps and improves the use efficiency, but also ensures that the top plate can be firmly fixed when it is recessed into the box body, preventing the sharps box from being accidentally opened;

[0015] In the present invention, the sharps box can achieve a double shielding effect by providing a hollow shielding plate to prevent the leakage of sharps. At the same time, the placement port on the top of the sealing ring and the card slot on the reinforcing plate make it convenient for medical staff to place sharps and remove needles and other sharps, further reducing safety risks. This design not only improves the practicality of the sharps box, but also fully considers the convenience of operation for medical staff.
