A sharps container 100 according to the present invention, as shown in fig. 1-3, comprises:

a cassette body 110 having an open-ended accommodation cavity 111 at which a feed port 112 and a discharge port 113 are formed;

a partition plate 130 configured to partition the accommodating chamber 111 into a first chamber 1111 and a second chamber 1112, and the partition plate 130 being capable of switching movement between a first position and a second position;

wherein, when the diaphragm 130 is moved to a first position, the first chamber 1111 communicates with the inlet port 112 and the second chamber 1112 communicates with the discharge port 113; when the diaphragm 130 is moved to a second position, the second chamber 1112 is in communication with the feed port 112 and the first chamber 1111 is in communication with the discharge port 113;

wherein the feed port 112 forms a cutting mechanism.

That is, when a medical sharp is to be treated, the diaphragm 130 is adjusted to a first position such that the first chamber 1111 communicates with the inlet port 112 and the second chamber 1112 communicates with the outlet port 113, and then the sharp to be treated is placed in the inlet port 112 and cut by the cutting mechanism so as to fall into the first chamber 1111; when a sharp implement located in the first chamber 1111 has stored a certain amount, the barrier 130 is adjusted to move to a second position such that the second chamber 1112 is in communication with the inlet port 112 and the first chamber 1111 is in communication with the discharge port 113, such that a sharp implement located in the first chamber 1111 is discharged from the discharge port 113; the sharp instrument box 100 can facilitate the falling of sharp instruments, and is convenient to use, safe, reliable and simple in structure.

In an example of the present invention, both ends of the accommodating chamber 111 form the open ends, respectively;

end caps 120 respectively covering the partially opened ends of the accommodating chamber 111 so that the feeding port 112 and the discharging port 113 are respectively formed at both ends of the cartridge body 110; the end caps 120 are fixedly coupled to the two open ends of the receiving cavity 111, and do not completely block the two open ends to form the material inlet port 112 and the material outlet port 113;

in other words, the material inlet port 112 and the material outlet port 113 are respectively located at two ends of the accommodating cavity 111, so that the sharp device can be conveniently put in and discharged without mutual influence;

it is understood that the inlet port 112 and the outlet port 113 at both ends of the receiving chamber 111 do not overlap in the orthogonal projection direction of each other, so that the movement can be switched between the first position and the second position when the partition 130 moves.

In one example of the present invention, the method further comprises: the pivot axis (140) is provided with a pivot axis,

pivotally coupled within the receiving cavity 111 and the partition 130 is fixedly coupled to the pivot shaft 140, the partition 130, the side wall of the receiving cavity 111 and the end cap 120 forming the first chamber 1111 and the second chamber 1112;

that is, the partition 130 includes two partitions and is spaced along the circumferential direction of the pivot shaft 140 to form two independent first and

second chambers

1111 and 1112, and when the pivot shaft 140 rotates, the partition 130 is driven to rotate synchronously with the pivot shaft, so as to move the positions of the first and

second chambers

1111 and 1112 relative to the chambers and the end cap 120, thereby realizing the switching between the first and second positions.

In one example of the present invention, the pivot shaft 140 is mounted on the end cover 120 through a bearing, and on the end cover 120 provided with the material inlet port 112, the pivot shaft 140 penetrates through the end cover 120 and extends in a direction away from the end cover 120;

specifically, a first mounting hole is formed in the end cover 120 of the discharge port 113, and the bearing includes an inner ring and an outer ring which are opposite to each other, wherein the inner ring of the bearing is fixedly coupled to the pivot shaft 140, and the outer ring of the bearing is fixedly coupled to the first mounting hole; the end cover 120 of the material inlet port 112 is provided with a second mounting hole, the bearing inner ring at the side end is fixedly connected with the pivot shaft 140, and the bearing outer ring is fixedly connected with the second mounting hole, so that the structure can realize the rotation movement of the pivot shaft 140 relative to the end cover 120 without influencing the connection relationship between the pivot shaft and the end cover.

In one example of the present invention, the method further comprises: a first limit nut 150 is provided on the outer surface of the casing,

is coupled with the pivot shaft 140 through screw threads and is arranged on one side of the end cover 120 for limiting the degree of freedom of the pivot shaft 140 in the circumferential direction;

that is, by screwing the first limit nut 150 to make its side end face abut against the end cap 120, so as to fix the pivot shaft 140, the first chamber 1111 and the second chamber 1112 are prevented from switching movement to affect the insertion and the discharge of the sharp instrument when the sharp instrument box 100 is used.

In one example of the present invention, the method further comprises: the position of the position limiting plate 160 is,

extending along the circumferential direction of the pivot shaft 140 and in a direction away from the pivot shaft 140 for defining the position of the first limit nut 150 on the pivot shaft 140;

it can be understood that the first limit nut 150 is defined between the end cap 120 and the limit plate 160, and the distance between the end cap 120 and the limit plate 160 is greater than the thickness of the first limit nut 150, so that the first limit nut 150 moves between the end cap 120 and the limit plate 160, and the fixing and releasing of the pivot shaft 140 are realized.

In one example of the present invention, the cutting mechanism comprises:

a first cutting edge 121 formed on at least one side of the feeding port 112 in the circumferential direction;

a second cutting edge 171 pivotably coupled to one side of the first cutting edge 121 and disposed opposite the first cutting edge 121;

wherein when the first cutting edge 121 and the second cutting edge 171 move towards each other, a shearing force is formed at the joint of the first cutting edge 121 and the second cutting edge 171;

that is, in use, relative movement is caused between the first edge 121 and the second edge 171 to create a shearing force at the junction between the two, placing a sharp article to be treated between them, and thereby shearing off and falling into the first chamber 1111.

In one example of the present invention, the method further comprises: the shear plate 170 is provided with a shear plate,

pivotally coupled to a side of an end cap 120 that provides the inlet port 112;

wherein at least one side edge of the shear plate 170 in the circumferential direction forms a second cutting edge 171;

that is, when the cutting mechanism is in use, the shear plate 170 is rotated relative to the end cap 120 of the inlet port 112, thereby creating shear forces between the shear plate 170 and the end cap 120;

preferably, the shear plate 170 is sleeved on the upper end of the limiting plate 160, and the lower end surface of the shear plate 170 abuts against the upper end surface of the limiting plate 160, so that the limiting plate 160 supports the shear plate 170.

Preferably, in order to rotate the pivot shaft 140, a transverse shaft 141 perpendicular to the pivot shaft 140 is fixedly disposed on the pivot shaft 140 on the side where the end cover 120 is disposed, and the transverse shaft 141 may be coupled to the pivot shaft 140 by, for example, integral molding or welding.

In one example of the utility model, the projection of the second edge 171 in the circumferential direction onto the plane of the first edge 121 is not coincident with the first edge 121;

that is, the first cutting edge 121 and the second cutting edge 171 may be disposed up and down, for example, the second cutting edge 171 may be disposed above the first cutting edge 121, which increases the shearing force between the shear plate 170 and the end cap 120; but also can completely cover the accommodating cavity 111, so that the processed sharp instrument in the accommodating cavity 111 can not be moved out, and the sharp instrument box 100 is safer.

In one example of the present invention, the method further comprises: a second stop nut 180 is provided on the outer surface of the casing,

is in threaded connection with the pivot shaft 140 and is arranged on one side of the shear plate 170 for limiting the freedom degree of the shear plate 170 in the circumferential direction;

that is, the second limit nut 180 is disposed at the upper end of the shear plate 170, and the shear plate 170 is fixed or released from the pivot shaft 140 by rotating the second limit nut 180; for example, when the sharps container 100 is not used, the material inlet 112 needs to be sealed by the shear plate 170, at this time, the shear plate 170 is rotated to cover the upper end of the material inlet 112, and then the second limiting nut 180 is rotated forward to make the position between the second limiting nut 180 and the shear plate 170 and the position between the shear plate 170 and the limiting plate 160 abut against each other, so as to fix the position of the shear plate 170; when the sharps container 100 is used, the second limit nut 180 is rotated in the reverse direction to release the relative rotation with the shear plate 170, thereby allowing the shear plate 170 to rotate relative to the pivot shaft 140 and serve to shear the sharps.

While the exemplary embodiment of the sharps container 100 proposed by the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the specific embodiments described above and various combinations of the various features and structures presented in the present invention without departing from the concept of the present invention, which is defined by the appended claims.
