DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0028] like Figure 1 to Figure 5 As shown, the embodiment discloses an improved box cover with scissors, including a fixed cover body 1 and a rotating cover body 2, wherein the fixed cover body 1 is provided with a fixed opening 1a at the top, the rotating cover body 2 is rotatably connected to the top of the fixed cover body 1, and a movable opening 2a is provided on the rotating cover body 2; a scissors body 3 and a card slot 4 are installed on the side of the top of the rotating cover body 2 close to the movable opening 2a, the scissors body 3 includes a lower scissors body 3.2 and an upper scissors body 3.1, the rear end of the lower scissors body 3.2 is rotatably connected to the rotating cover body 2, the upper scissors body 3.1 is arranged above the lower scissors body 3.2, and the rear ends of the upper scissors body 3.1 and the lower scissors body 3.2 are hinged through a scissors shaft 3.3; the card slot 4 is fixedly installed on the rotating cover body 2, and the front end of the scissors body 3 can be moved into or out of the card slot 4 when the scissors body 3 is rotated. The card slot 4 is L-shaped.

[0029] like Figure 4 , Figure 5 As shown, in this embodiment, the upper scissors body 3.1 includes an upper scissors seat 3.1a and an upper shear blade 3.1b, and the lower scissors body 3.2 includes a lower scissors seat 3.2a and a lower shear blade 3.2b. The rear ends of the upper scissors seat 3.1a and the lower scissors seat 3.2a are hinged by the scissors shaft 3.3, the upper shear blade 3.1b is injection-molded and fixed on the lower surface of the upper scissors seat 3.1a, and the lower shear blade 3.2b is injection-molded and fixed on the upper surface of the lower scissors seat 3.2a. Both the upper shear blade 3.1b and the lower shear blade 3.2b are arc-shaped. When the upper scissors body 3.1 moves downward, the upper shear blade 3.1b and the lower shear blade 3.2b are interlaced and tightly fitted with each other. The scissors shaft 3.3 is sleeved with two torsion springs 3.4, which are respectively installed at both ends of the scissors shaft 3.3, one end of the torsion spring 3.4 is connected to the upper scissors body 3.1, and the other end is connected to the lower scissors body 3.2. The torsion spring 3.4 drives the upper scissors body 3.1 to automatically open upwards when not subject to pressing pressure.

[0030] During clinical use, when the sharps box is not activated, the front end of the scissors body 3 is retracted into the card slot 4 to ensure safe storage and keep the scissors functioning intact. When the sharps box is activated, rotate the rotating cover 2 so that the movable opening 2a on the rotating cover 2 corresponds to the fixed opening 1a on the fixed cover 1; then rotate the scissors body 3 so that the front end of the scissors body 3 moves out of the card slot 4, and the upper scissors body 3.1 automatically pops up under the action of the torsion spring 3.4; then put the sharps that need to be sheared [such as infusion needles] between the upper scissors body 3.1 and the lower scissors body 3.2, and then press down hard. The upper shear blade 3.1b and the lower shear blade 3.2b can be staggered to perform the shear separation operation on the sharps. The downward pressure cutting method makes the separation operation very labor-saving, more precise, and more labor-saving. The arc-shaped upper shear blade 3.1b and the lower shear blade 3.2b make the separation operation more precise.

[0031] In this embodiment, the connection structure between the rear end of the lower shear body 3.2 and the rotating cover body 2 is as follows: Figure 4As shown, a connecting shaft 3.2c is provided at the bottom of the rear end of the lower scissor body 3.2, a connecting hole 2b is provided on the rotating cover body 2, the connecting shaft 3.2c is penetrated into the connecting hole 2b, and a teardrop-shaped head is provided at the lower end of the connecting shaft 3.2c, and the maximum outer diameter of the teardrop-shaped head is larger than the inner diameter of the connecting hole 2b to prevent the connecting shaft 3.2c from escaping from the connecting hole 2b. With such arrangement, when the sharps box is two-thirds full and needs to be sealed, the scissors main body 3 is rotated so that the front end of the scissors main body 3 is suspended in the movable opening 2a, and the upper scissors body 3.1 is pressed hard until the scissors main body 3 is completely closed, and then the front end of the upper scissors body 3.1 is continued to be pressed hard. Since the front end of the scissors main body 3 is suspended, according to the lever principle, the rear end of the lower scissors body 3.2 will be warped, and the connecting shaft 3.2c will be subjected to an upward pulling force. Since the lower end of the connecting shaft 3.2c is a teardrop-shaped head, when the pulling force applied to the connecting shaft 3.2c reaches a certain level, the connecting shaft 3.2c will come out of the connecting hole 2b, and the scissors main body 3 will be peeled off and slide into the sharps box jar; then the rotating cover body 2 is rotated until it is completely closed. At this time, the movable opening 2a on the rotating cover body 2 is staggered with the fixed opening 1a on the fixed cover body 1, and the connecting hole 2b originally installed with the connecting shaft 3.2c will also be blocked by the fixed cover body 1, and the entire sharps box is completely closed, effectively ensuring medical safety.

[0032] like Figure 6 As shown, the connection hole 2b is surrounded by a minor arc notch 2e extending to the movable opening 2a, and the central angle corresponding to the narrowest part of the minor arc notch 2e is less than 180 degrees, preferably less than 90 degrees. This arrangement allows the connection shaft 3.2c to be more easily removed from the connection hole 2b, facilitating the smooth peeling of the scissors body 3.

[0033] like Figure 4 As shown, in this embodiment, the lower surface of the upper scissor seat 3.1a is provided with a concave cavity 3.1c, and the upper cutting blade 3.1b is arranged at the bottom of the concave cavity 3.1c. The shape of the concave cavity 3.1c matches the shape of the lower scissor seat 3.2a. When the scissors body 3 is completely closed, the upper scissors seat 3.1a is covered on the lower scissors seat 3.2a through the concave cavity 3.1c. In this way, the integrity of the scissors body 3 after closing is better, and the upper cutting blade 3.1b and the lower cutting blade 3.2b are completely wrapped between the upper scissors body 3.1 and the lower scissors body 3.2, and the safety is also higher.

[0034] In this embodiment, the connection structure between the rotating cover body 2 and the fixed cover body 1 is as follows: Figure 2As shown, the top of the fixed cover 1 is provided with a circular groove 1b, the bottom center of the circular groove 1b is provided with an embedding hole 1c, the rotating cover 2 is installed in the circular groove 1b, the bottom center of the rotating cover 2 is provided with a connecting column, the connecting column is inserted in the embedding hole 1c, and the periphery of the rotating cover 2 is provided with an extended edge 2c extending upward. With such a configuration, when the cut sharp object accidentally fails to fall into the sharp object box can smoothly, the extended edge 2c can also play a blocking role to prevent the sharp object from rolling to the ground.

[0035] like Figure 1 , Figure 3 As shown, in this embodiment, an arc-shaped notch 2d is provided on the side of the rotating cover 2. Such a configuration makes it more convenient and labor-saving for medical personnel to rotate the rotating cover 2. A needle stripping port 1d is provided on the fixed cover 1 to facilitate separation of the syringe from the needle.

[0036] The rotating cover body 2 and the fixed cover body 1 in the present invention are preferably made of plastic.

[0037] The above description is only a preferred embodiment of the present invention, and the above specific embodiment is not intended to limit the present invention. Various deformations and modifications may occur within the scope of the technical concept of the present invention, and any modification, modification or equivalent replacement made by a person of ordinary skill in the art based on the above description shall fall within the scope of protection of the present invention.
