DETAILED DESCRIPTION
[0029] The screw-top sharps box comprises a rotary sealing plate 1, a sealing bottom cover 2 and a recovery box body 3 (see the attached manual). Figure 1 and 2 The rotary sealing plate 1, the sealing bottom cover 2 and the recovery box body 3 are all injection-molded by plastic materials.
[0030] The upper end of the recovery box body 3 is buckled with a sealed bottom cover 2 (see the attached manual). Figure 1 and 2 The upper end of the recovery box body 3 is provided with an annular flange 4 (see the attached manual). Figure 2 and 11 ).
[0031] A locking boss 5 is provided on the inner side of the bottom end of the sealing bottom cover 2; a guide slope 6 is provided on one side below the locking boss 5 (see the appendix of the manual). Figure 11 ).
[0032] The purpose of providing the sealing bottom cover 2 in this manner is to enable the sealing bottom cover 2 to be fastened to the upper end of the recovery box body 3 during assembly, and then pressed downward. During this process, the locking boss 5 of the recovery box body 3 is pressed by the guide slope 6 to deform and expand outward. When the locking boss 5 moves to the lower end surface of the annular flange 4, the recovery box body 3, under the action of its own elastic force, snaps the locking boss 5 onto the lower end surface of the annular flange 4, thus locking the sealing bottom cover 2 to the upper end of the recovery box body 3.
[0033] The upper end of the sealed bottom cover 2 is provided with an avoidance sink 10 (see the appendix of the specification). Figure 7 A plurality of limit blocks 11 are evenly arranged on the upper edge of the avoidance trough 10. A center hole 12 is arranged in the center of the avoidance trough 10 (see the appendix of the specification). Figure 7 and 8 ).
[0034] A material dropping hole 13 and a teardrop-shaped peeling hole 14 are provided on one side of the central hole 12 (see the appendix of the manual for details). Figure 7 and 8 The purpose of providing the material-discarding hole 13 and the peeling hole 14 is to allow a single medical sharp object, such as a small glass product, to be directly discarded into the recovery box 3 through the material-discarding hole 13. For a needle mounted on a syringe, it can first be inserted into the peeling hole 14, with the upper end of the needle stuck on the lower end surface of the "teardrop"-shaped peeling hole 14. The syringe can then be pulled to separate the needle from the needle, and the needle can then fall into the interior of the recovery box 3 under the action of gravity, thus completing the needle recovery process.
[0035] The sealing bottom cover 2 is provided with a rotary sealing plate 1 through the center hole 12 (see the appendix of the manual). Figure 1 and 2 The rotary sealing plate 1 is located inside the avoidance tank 10. A plurality of positioning blocks 15 are evenly arranged on the circumferential surface of the rotary sealing plate 1 (see the appendix of the specification). Figure 6 ).
[0036] The purpose of setting the positioning block 15 is to enable the rotating sealing plate 1 to be pressed into the inside of the avoidance groove 10 of the sealing bottom cover 2 after the positioning block 15 on the rotating sealing plate 1 is offset from the upper limit block 11 on the sealing bottom cover 2 during assembly; when the rotating sealing plate 1 is installed in the inside of the avoidance groove 10, the positioning block 15 of the rotating sealing plate 1 is located below the limit block 11, so that the limit block 11 can confine the rotating sealing plate 1 to the inside of the sealing bottom cover 2 through the positioning block 15, thereby avoiding the problem of easy separation between the rotating sealing plate 1 and the sealing bottom cover 2.
[0037] The bottom of the rotary sealing plate 1 is symmetrically provided with a clamping claw 18 (see the appendix of the specification). Figure 5 and12 The clamping claw 18 is a semi-cylindrical structure; a clamping boss 19 is provided on the outer side of the lower end of the clamping claw 18; a guiding slope 20 is provided on the lower end of the clamping boss 19 (see the appendix of the specification). Figure 5 and 12 ).
[0038] The purpose of providing the engaging claws 18 in this manner is to enable, during operation, the engaging claws 18 to be aligned with the center hole 12 on the sealing bottom cover 2, and then the rotary sealing plate 1 to be pressed downward. At this time, the center hole 12 will squeeze the engaging claws 18 through the guiding inclined surfaces 20, so that the engaging claws 18 are brought closer to each other. When the engaging boss 19 is moved downward to the lower end surface of the center hole 12, the engaging claws 18 are reset under the action of the elastic force, so that the engaging boss 19 is engaged and connected with the center hole 12. In this way, the installation of the rotary sealing plate 1 is completed, and the rotary sealing plate 1 can rotate relative to the sealing bottom cover 2 when subjected to force.
[0039] The upper end surface of the rotary sealing plate 1 is provided with an operating ring edge 16 (see the appendix of the specification). Figure 5 and 6 During operation, the rotary sealing plate 1 can be driven to rotate by operating the ring edge 16 .
[0040] The rotary sealing plate 1 on the inner side of the operating ring edge 16 is provided with a leakage avoidance hole 17 (see the appendix of the manual). Figure 6 During operation, when the leakage avoidance hole 17 corresponds to the material loss hole 13 and the peeling hole 14, medical sharps can be dropped into the recovery box body 3 through the material loss hole 13 and the peeling hole 14. When the sealing plate 1 is rotated to block the material loss hole 13 and the peeling hole 14, the upper end of the screw-top sharps box can be sealed, thereby preventing medical sharps from spilling out of the screw-top sharps box.
[0041] The lower end surface of the rotary sealing plate 1 is provided with an anti-rotation hook 21; the upper end of the sealing bottom cover 2 is provided with an arc-shaped avoidance groove 22; the inner part of the arc-shaped avoidance groove 22 is provided with an anti-rotation spring piece 23 (see the appendix of the manual) Figure 6 、 8 , 9 and 10).
[0042] The purpose of providing the anti-rotation hook 21 and the anti-rotation spring 23 is to enable, when a certain number of medical sharps are contained in the recovery box body 3 and the sharps box is to be recycled, the rotary sealing plate 1 can be rotated so that the anti-rotation hook 21 enters the upper end of the sealing bottom cover 2 along the arc-shaped avoidance groove 22, and finally squeezes the anti-rotation spring 23 so that they are hooked together. After the anti-rotation hook 21 and the anti-rotation spring 23 are hooked together, when the rotary sealing plate 1 continues to rotate forward, the anti-rotation hook 21 will conflict with the end of the arc-shaped avoidance groove 22, and when the rotary sealing plate 1 rotates reversely, the anti-rotation hook 21 will conflict with the anti-rotation spring 23. In this way, the rotary sealing plate 1 and the sealing bottom cover 2 can be fixed to each other, thereby achieving the purpose of preventing the medical sharps inside the sharps box from being taken out for secondary use after the sharps box is recycled.
[0043] The sealing bottom cover 2 inside the recovery box body 3 is provided with a reinforcing skirt 24 (see the appendix of the manual). Figure 11 ) or multiple reinforcing ribs 25 (see the attached instructions Figure 7 The reinforcing skirt 24 and the reinforcing rib 25 are in contact with the inner wall of the recovery box body 3.
[0044] The purpose of providing the reinforcing skirt 24 and the reinforcing ribs 25 is to enable the reinforcing skirt 24 and the reinforcing ribs 25 to provide support for the recovery box body 3 from the inside after the sealing bottom cover 2 is assembled during operation, thereby avoiding the problem that the existing recovery box body 3 is easily deformed due to force and causes medical sharps to be scattered.
[0045] A plurality of accommodating cavities 7 are evenly arranged on the arc surface of the sealing bottom cover 2 above the locking boss 5; elastic hook claws 8 are installed in the accommodating cavities 7; a plurality of locking grooves 9 are evenly arranged on the circumferential surface of the annular flange 4 of the recovery box body 3; the elastic hook claws 8 are connected with the corresponding locking grooves 9 by snapping (see the appendix of the manual). Figure 3 and 4 ).
[0046] The purpose of providing the accommodating cavity 7, the elastic hook 8, and the locking groove 9 is to ensure that during the assembly process of the sealed bottom cover 2, after it is buckled onto the upper end of the recovery box body 3, the sealed bottom cover 2 can be rotated to rotate the elastic hook 8 to correspond to the locking groove 9. The elastic hook 8 can then be snapped into the interior of the locking groove 9 under the action of its own elastic force and connected to the recovery box body 3. In this way, the sealed bottom cover 2 can be fixedly connected to the recovery box body 3 through the elastic hook 8 and the locking groove 9, thereby strengthening the connection strength between the sealed bottom cover 2 and the recovery box body 3, thereby reducing the risk of separation between the sealed bottom cover 2 and the recovery box body 3.
[0047] The screw-cap sharps box has a compact structure and ingenious design. By optimizing the structure of the rotating sealing plate 1 and the sealing bottom cover 2, the recovery box body 3 and the sealing bottom cover 2 can be locked to form an integrated structure. When the rotating sealing plate 1 is closed, it cannot be opened by non-violent means, thereby achieving the purpose of preventing secondary utilization and solving the problems of easy leakage and high safety risks of existing sharps boxes. The box is particularly suitable for the recycling of medical sharps.
