Detailed ways

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

Example 1

As shown in Figure 1, Embodiment 1 discloses a safety-type sharps box with a cutter, including a box body 1 and a box cover 2, a cutting hole 2a is opened in the center of the top of the box cover 2, and the inside of the box body 1 is A vertically arranged rotating shaft 3 is installed, the lower end of the rotating shaft 3 is rotatably installed in the center of the bottom of the box body 1, and the upper end of the rotating shaft 3 is fixedly equipped with a cross-shaped blade 4, and the cross-shaped blade 4 is connected to the box cover at the cutting hole 2a. 2. The lower surface is close to each other; a worm wheel 5 is fixedly installed on the rotating shaft 3, and a worm 6 is arranged on the side of the worm wheel 5, and the worm 6 is engaged with the worm wheel 5, and one end of the worm 6 is supported and installed in a bearing 7 with a seat , the bearing 7 with a seat is fixed on the bottom of the box body 1; the other end of the worm 6 is a protruding end, and the protruding end runs through the side wall of the box body 1, and a bearing 8 supporting the protruding end is installed on the side wall of the box body 1, The protruding end of the worm screw 6 is connected with a driving device. In the first embodiment, the driving device adopts a crank handle 9 , and the head end of the crank handle 9 is detachably connected with the protruding end of the worm 6 .

During specific use, the user inserts the tip of the thong and the needle into the cutting hole 2a, and then manually rotates the handle 9, which drives the worm 6 to rotate, and the worm 6 drives the worm wheel 5 and the rotating shaft 3 to rotate, so that the shaft installed on the upper end of the rotating shaft 3 The cross-shaped blade 4 starts to rotate, and the cross-shaped blade 4 cooperates with the cutting hole 2a to cut the leather strip tip and the needle. Since the cross-shaped blade 4 is arranged inside the box body 1, personnel will not come into contact with it, which is safer, and there is no need to pick up the needle and put it in again, so there is no risk of needle stick injury. Since the crank handle 9 is detachable, such a crank handle 9 can drive a plurality of safe sharp tool boxes, which saves cost and also reduces the storage space of the safe sharp tool boxes.

As shown in Figure 1, in the present embodiment 1, the protruding end of the worm 6 is set as a regular polygon, and the head end of the handle 9 is provided with a regular polygonal concave hole matching the shape of the protruding end of the worm 6 , The crank handle 9 is sleeved with a rotating sleeve 9a. Such arrangement enables the head end of the crank 9 to be docked with the protruding end of the worm 6 conveniently and quickly, and the rotating sleeve 9a makes the crank 9 rotate more flexibly.

As shown in FIG. 2 , in the first embodiment, the cross-shaped blade 4 is a cross-shaped blade 4 . With such arrangement, the cutting can be implemented more effectively. The outer circumference of the cross blade 4 is also provided with a reinforcement ring 10, and the outer end of the cross blade 4 is integrally connected with the reinforcement ring 10, which can greatly improve the firmness of the cross blade 4 and improve its service life.

As shown in Figure 2, in this embodiment 1, the rotating shaft 3 includes a fixed shaft 3.1 and a moving shaft 3.2, the lower end of the fixed shaft 3.1 is rotatably installed at the bottom center of the box body 1, and a spline hole is provided inside the upper end of the fixed shaft 3.1 , the outer wall of the lower end of the moving shaft 3.2 is provided with a spline, the lower end of the moving shaft 3.2 is inserted into the spline hole on the fixed shaft 3.1, and a spring 3.3 is arranged between the lower end of the moving shaft 3.2 and the upper end of the fixed shaft 3.1, and the cross Type blade 4 is fixedly installed on the moving shaft 3.2 upper end. Such setting, on the one hand, can keep the cross-shaped blade 4 in close contact with the cutting hole 2a to ensure the cutting effect; cause self damage.

As shown in Figure 2, in this embodiment 1, the lower surface of the top of the box body 1 is provided with an inner hexagonal mounting groove around the cutting hole 2a, and a cutting piece 11 is arranged in the inner hexagonal mounting groove. The outer periphery of the cutting piece 11 is hexagonal and matches the inner hexagonal installation groove, and the inner hole of the cutting piece 11 is circular and its inner diameter is smaller than or equal to the inner diameter of the cutting hole 2a. With such an arrangement, the cutting piece 11 can be disassembled and replaced, and it is sufficient to replace with a new cutting piece 11 when the cutting effect becomes poor. Preferably, the inner peripheral edge of the cutting piece 11 is provided with serrations 11a. Such a setting can prevent the items from running during the cutting process and improve the cutting efficiency.

As shown in Figure 2, in the present embodiment 1, a partition 12 is provided in the lower part of the box body 1, a support platform 13 is provided on the inner wall of the lower part of the box body 1, and the edge of the partition plate 12 rests on the support platform 13 , the center of the partition 12 is provided with a through hole, the rotating shaft 3 passes through the through hole, and an auxiliary support bearing 14 is installed in the through hole; the box body 1 is screwed with the box cover 2 . Set in this way, the partition 12 can prevent the cut pimp tip or needle from falling between the worm screw 6 and the worm wheel 5, so as to avoid causing the device to be stuck, and the auxiliary support bearing 14 plays the role of auxiliary supporting the rotating shaft 3 to ensure that the rotating shaft 3 runs smoothly. When there are too many leather strip tips and needles in the box body 1, the lid 2 can be rotated open, and the leather strip tips and needles can be poured out, so that the safety sharps box with cutter can continue to be used.

Example 2

As shown in Figure 5, Embodiment 2 discloses a safety-type sharps box with a cutter, which is different from Embodiment 1 in that the drive device adopts a motor 15, and the output shaft of the motor 15 and the extension of the worm 6 The ends are connected by couplings. So set, the motor 15 is controlled by a switch, and the switch of the motor 15 is turned on during use, and the motor 15 is energized to drive the worm screw 6 to rotate, thereby driving the cross blade 4 to rotate.

Example 3

As shown in Figures 6 to 8, Embodiment 3 discloses a safety sharps box with a cutter, which differs from Embodiments 1 and 2 in that: the side wall of the box body (1) is provided with a side opening , a drawer-type storage barrel (16) is housed in the side opening, the shape of the tail of the drawer-type storage barrel (16) matches the shape of the side wall of the box body (1), and the front end of the drawer-type storage barrel (16) is provided for avoiding Make way for the notch (16a) of the rotating shaft (3). So set, when in use, the leather strip tip or the needle after cutting above directly falls in the drawer-type storage barrel (16), and the drawer-type storage barrel (16) can be taken out and dumped conveniently after it is full, if it is temporarily inconvenient to topple over, you can Cover the drawer-type storage barrel (16) with an adapted lid and wait for centralized dumping, and reload an empty drawer-type storage barrel (16) in the box body (1).

The above descriptions are only preferred embodiments of the present invention, and the above specific embodiments do not limit the present invention. Within the scope of the technical idea of the present invention, various deformations and modifications may occur, and any retouching, modification or equivalent replacement made by those skilled in the art based on the above description shall fall within the protection scope of the present invention.
