Description

Technical Field

[0001] The present application relates to the technical field of medical waste recycling, and in particular to a contactless cutting sharps box. Background Art

[0002] In the medical system, the recycling of sharp instruments is usually packed together in a sharps box, and then handled by a medical waste treatment unit. Since medical waste is charged by quality when it is recycled, medical staff usually sort the medical waste and cut off the sharp parts, such as cutting off the needle part of the infusion tube with scissors. The above operation increases the risk of medical staff being cut by sharp instruments or infected with bacteria. For this reason, Chinese invention patent CN2024108852770 discloses a sharps box with a built-in cutting function. By using this sharps box, there is no need to use additional tools for cutting operations, and the separation of the infusion tube and the needle can be completed through the built-in cutting function.

[0003] However, the above-mentioned sharps box has the following disadvantages when in use: 1. The upper and lower scissor arms are driven by a cam to engage with each other, and the upper and lower scissor arms are exposed from the shell periodically, which makes the upper and lower scissor arms extend for a short time and may retract before contacting the infusion tube, making it impossible to achieve the purpose of cutting. 2. Infusion tubes or other drainage tubes are usually tough. Although the upper and lower scissor arms complete the action of engaging with each other during movement, it cannot ensure that the tough pipeline has been cut. Therefore, it is urgent to develop and design a sharps box that can actually cut pipelines and prevent sharp objects from contacting staff. Summary of the invention

[0004] The invention provides a contactless cutting sharp tool box, which is equipped with an upper rocker arm and a lower rocker arm, and the movement of the upper and lower rocker arms drives the upper and lower blades to act on the pipeline repeatedly to ensure that the pipeline is cut off.

DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present application applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present application and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present application.

[0022] It should be clear that the embodiments described below are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by technicians in the relevant field without making creative work are within the scope of protection of the present application. Example

[0023] like Figure 1-Figure 7 As shown, the contactless cutting sharp tool box includes a cutting device and a receiving tube 27, and the cutting device includes a fixing frame 5, an upper rocker arm 15, a lower rocker arm 19, a rotating motor 6 and a driving wheel 7; The ends of the upper rocker arm 15 and the lower rocker arm 19 are both rotatably connected to the fixed frame 5. The upper rocker arm 15 is provided with an upper blade 16, and the lower rocker arm 19 is provided with a lower blade 18. The upper blade 16 and the lower blade 18 are used to cut the infusion tube after being engaged. The output end of the rotating motor 6 is fixed to the driving wheel 7, and the driving wheel 7 is rotatably set on the fixed frame 5. The driving wheel 7 is provided with an arc guide groove 25, and the number of the arc guide grooves 25 is two. The upper rocker arm 15 and the lower rocker arm 19 are both provided with a slider, and the slider is correspondingly slidably connected with the arc guide groove 25. The accommodating cylinder 27 is provided with a through hole 33 adapted to the fall of a sharp weapon, and the through hole 33 is located below the lower rocker arm 19. The lower end of the fixed frame 5 is provided with a fixed shell 11, and the fixed shell 11 can be detachably buckled on the top of the accommodating cylinder 27.

[0024] The connection relationship and working principle of the cutting device components are as follows: like Figure 3 and Figure 4 As shown, when the pipe with a sharp tool is placed between the upper blade 16 and the lower blade 18. Since the rotating motor 6 (servo motor) drives the driving wheel 7 to rotate periodically and repeatedly, the upper rocker arm 15 and the lower rocker arm 19 can be driven to move toward each other. The above principle is: An arc-shaped guide groove 25 is provided on the driving wheel 7, and sliders are provided on the upper rocker arm 15 and the lower rocker arm 19. When the driving wheel 7 rotates back and forth, the slider can be driven to move through the arc-shaped guide groove 25, so that the upper rocker arm 15 and the lower rocker arm 19 move toward each other, and the pipeline placed between the two blades is repeatedly cut until the pipeline is cut off. Example

[0025] This embodiment further describes the positioning device based on the above embodiment: like Figure 5 and Figure 6 As shown, this embodiment also includes a positioning device, which includes a fixed block 9, a slider 13, a driving block 12, a sliding block 31, a connecting block 30, a claw 29 and a transmission assembly; The fixed block 9 is fixedly arranged on the upper end of the fixed sleeve 11; one end of the driving block 12 is rotatably connected to the slider 13, and the other end is rotatably connected to the sliding block 31. The fixed block 9 is provided with a transverse slide rail 28, and the sliding block 31 is slidably connected to the transverse slide rail 28; one end of the connecting block 30 is fixed to the sliding block 31, and the other end is fixed to the claw 29; the slider 13 and the cutting device are transmission-connected through a transmission assembly. The fixed block 9 is provided with a vertical slide rail 1, and the slider 13 is slidably connected to the vertical slide rail 1. The fixed block 9 is provided with a rotating seat 34, and the driving block 12 is rotatably connected to the rotating seat 34.

[0026] The component connection relationship and working principle of the positioning device are as follows: In order to more accurately place the pipeline between the upper blade 16 and the lower blade 18 and avoid the worker from contacting the sharp end as much as possible, the pipeline is passed through the through hole on the fixing block 9 (the shape and size of the through hole can be adjusted according to the shape of the pipeline and the sharp end), and the exposed end of the sharp end is exactly located between the upper blade 16 and the positioning hole 17.

[0027] In order to prevent the pipeline from deflecting or moving during the cutting process, when the slider 13 moves upward, it can drive the upper end of the driving block 12 to move upward. At this time, the lower end of the driving block 12 moves toward the center of the fixed housing 11. Figure 5 and Figure 6 As shown, during the movement, the driving block 12 will drive the sliding block 31 to move to the right, and the driving block on the right will drive the sliding block on the right to move to the left, so that the two claws 29 will clamp the pipeline tightly to prevent the sharp end of the pipeline from swinging when cutting. Example

[0028] Based on the above embodiment, this embodiment further explains the transmission component: like Figure 7 As shown, the transmission assembly includes a transmission plate 2, a connecting rod 8, a rotating wheel 3, a rod 20, and a transmission belt 4. The rotating wheel 3 and the driving wheel 7 are synchronously connected through the transmission belt 4. The transmission plate 2 and the rotating wheel 3 are meshed and connected. One end of the connecting rod 8 is fixed to the slider 13, and the other end is fixed to the transmission plate 2. One end of the rod 20 is fixed to the rotating seat 34, and the other end is rotatably connected to the rotating wheel 3.

[0029] In this embodiment, the positioning device also includes a buffer assembly, which includes a buffer spring 23, a slide rod 22, a lower positioning block 24 and an upper positioning block 21. The lower positioning block 24 is fixed to the fixed block 9, the upper positioning block 21 is fixed to the slider 13, the slide rod 22 is fixed to the upper end of the lower positioning block 24, one end of the buffer spring 23 is fixed to the upper positioning block 21, and the other end is fixed to the lower positioning block 24. The upper positioning block 21 is provided with a through hole adapted for the slide rod 22 to slide through.

[0030] In this embodiment, the fixing block 9 is provided with a positioning hole 17 adapted for the infusion tube to pass through.

[0031] The advantages of the transmission assembly are: The design of the transmission assembly mainly ensures the simultaneous clamping of the pipeline and cutting of the sharp end of the pipeline. Specifically: In cutting state: Figure 7 For example, the driving wheel 7 moves counterclockwise, and when the driving wheel 7 rotates, the rotating wheel 3 is driven to rotate counterclockwise through the transmission belt 4. At this time, the rotating wheel 3 drives the transmission plate 2 to move upward, and then drives the slider 13 that moves synchronously with the transmission plate 2 to move upward. When the slider 13 moves upward, it can drive the claws on both sides to move toward each other, so as to clamp and fix the pipeline.
