DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 9 The present invention provides a technical solution: a collection box for used syringes for animal husbandry and veterinary medicine, comprising a plurality of groups of base cylinders 4 arranged on the box body and used for separating and processing used syringes, the syringes are composed of a barrel 1, a needle seat 2 and a needle body 3, the box body is provided with a tube placement area for accommodating the barrel 1 and a needle placement area for accommodating the needle body 3, and the plurality of groups of base cylinders 4 are provided with a separation structure for separating and processing the barrel 1 and the needle body 3 in the syringe; The fixing and separation structure includes a primary fixing assembly for clamping and fixing the cylinder body 1 and a secondary fixing assembly for clamping and fixing the needle seat 2. A hollow center cylinder 5 is provided below the base cylinder 4. The hollow center cylinder 5 is fixedly connected to the base cylinder 4. A separation assembly for driving the needle seat 2 to rotate horizontally to drive the needle seat 2 to separate from the cylinder body 1 is provided on the hollow center cylinder 5. A placement frame 34 is provided below the hollow center tube 5 , and the placement frame 34 is fixedly connected to the box body. A transverse bending component for bending the needle body 3 and driving the needle body 3 into the needle placement area is provided on the placement frame 34 .

[0020] like Figure 1 and Figure 2 As shown, when the waste syringe is processed, the syringe is placed in one of the groups of base cylinders 4 set on the box, wherein the bottom of the cylinder 1 contacts the inner bottom surface of the base cylinder 4, and the needle seat 2 and the needle body 3 pass through the base cylinder 4, wherein the cylinder 1 and the needle seat 2 are clamped and fixed by the primary clamping assembly and the secondary clamping assembly respectively, and the separation assembly drives the secondary clamping assembly to rotate to drive the needle seat 2 to rotate synchronously, thereby separating the needle seat 2 from the cylinder 1.

[0021] At the same time, when the needle seat 2 is separated from the cylinder 1 by the drive of the separation component, the primary clamping component and the secondary clamping component subsequently contact the cylinder 1 and the needle seat 2 to clamp and fix them, and then under the action of gravity, the needle seat 2 and the needle body 3 separated from the cylinder 1 fall into the placement frame 34, and then, driven by the transverse bending component, the needle body 3 can be bent to a certain extent at the placement frame 34, and the bent needle body 3 can be transferred to the needle placement area, and the cylinder 1 is manually picked up and placed in the tube placement area.

[0022] Among them, the cylinder 1 and the needle body 3 connected in a spiral manner can be separated by the fixed structure, thereby realizing the classified placement of the cylinder 1 and the needle body 3. In the subsequent processing process, the risk of medical staff being stabbed by the needle body 3 during the processing is reduced to avoid cross infection. At the same time, the cylinder 1 and the needle body 3 in the disposable syringe are made of different materials. The cylinder 1 and the needle body 3 are placed independently, which is convenient for the subsequent recycling and treatment of different medical wastes. Through the automatic separation of the cylinder 1 and the needle body 3, no manual operation is required to avoid sharp injuries caused by direct contact with the needle body 3.

[0023] In one of the more preferred embodiments, the main clamping assembly includes a hollow column 6 that slides through the hollow center tube 5 and moves freely in the vertical direction, and the end of the hollow column 6 away from the base tube 4 is provided with a bottom ring frame 12 that rotates freely in the horizontal direction, and the bottom ring frame 12 rotates on the hollow center tube 5 with a fixed axis; The hollow center cylinder 5 is fixedly sleeved with an axial block 39, an L-shaped vertical rod 26 is slidably penetrated through the axial block 39, and a rectangular groove for the L-shaped vertical rod 26 to be slidably connected is provided on the axial block 39, and a positioning pin 24 is fixedly connected to one end of the L-shaped vertical rod 26 facing the bottom ring frame 12, and an arc-shaped positioning groove 25 for the positioning pin 24 to be slidably connected is provided on the bottom ring frame 12; The base cylinder 4 is provided with a groove body for the L-shaped vertical rod 26 to slide through, and the base cylinder 4 is provided with two groups of outer clamping plates 27 that move synchronously toward or away from each other in the horizontal direction. The outer clamping plates 27 are fixedly connected to the L-shaped vertical rod 26, and the outer clamping plates 27 are provided with inner pressure plates 28 that are in contact with the cylinder body 1, and the outer clamping plates 27 are provided with vertical sliding grooves for the inner pressure plates 28 to slide and connect.

[0024] A hollow ball head 10 is fixedly passed through one end of the hollow column 6 toward the bottom ring frame 12, a ball seat 11 is provided inside the spiral limiting groove 14, and a ball cavity for the hollow ball head 10 to be slidably connected is opened on the ball seat 11; The outer circumference of the ball seat 11 is fixedly connected to a limiting pin 13 , and the bottom ring frame 12 is provided with a spiral limiting groove 14 for the limiting pin 13 to be slidably connected.

[0025] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, when the hollow column 6 moves freely in the vertical direction, it can drive the hollow ball head 10 fixed and passed through below it to move synchronously, wherein the hollow ball head 10 is slidably set on the ball seat 11 through the ball cavity, thereby driving the ball seat 11 and the hollow column 6 to rise and fall synchronously.

[0026] At the same time, the ball seat 11 is fixedly provided with a limit pin 13 on the bottom ring frame 12 which is slidably connected through a spiral limit groove 14. When the height of the ball seat 11 changes, the limit pin 13 can be driven to slide on the spiral limit groove 14 and drive the bottom ring frame 12 to rotate a certain angle in the horizontal direction. At the same time, the axial block 39 slides through an L-shaped vertical rod 26 which is fixedly connected to the outer clamping plate 27, and the L-shaped vertical rod 26 is fixedly provided with a co-positioning pin 24 which is slidably connected to the bottom ring frame 12 through an arc-shaped co-positioning groove 25. Therefore, when the bottom ring frame 12 rotates in the horizontal direction, the horizontal position of the L-shaped vertical rod 26 and the outer clamping plate 27 thereon can be changed through the arc-shaped co-positioning groove 25, so as to achieve the purpose of fixing the cylinder 1 when the inner pressure plate 28 provided on the outer clamping plate 27 squeezes and contacts the outer clamping plate 27.

[0027] Among them, the inner pressure plate 28 is slidably connected to the outer clamping plate 27 through a vertical slide groove. In actual use, the inner pressure plate 28 is squeezed and contacted with the outer peripheral surface of the cylinder 1 to realize the fixing process of the cylinder 1. When the separation component is running to drive the needle seat 2 to rotate, when a spiral connection is adopted between the needle seat 2 and the cylinder 1, it is necessary to set a space for the needle seat 2 or the cylinder 1 to move vertically, so as to drive the screw connection position of the two to be disengaged. Therefore, by driving the inner pressure plate 28 and the outer clamping plate 27 to be slidably connected, the horizontal movement of the outer clamping plate 27 is used to drive the inner pressure plate 28 to fix the cylinder 1. During the operation of the separation component, as the needle seat 2 rotates, the inner pressure plate 28 can slide vertically on the outer clamping plate 27 to provide redundant space for the screw connection position of the cylinder 1 and the needle seat 2, so as to avoid the needle seat 2 being able to disengage from the cylinder 1 when it rotates.

[0028] On the basis of the primary clamping assembly embodiment, the secondary clamping assembly includes a plurality of groups of pressing blocks 19 disposed on the base cylinder 4 and abuttingly connected with the needle seat 2, a connecting rod 18 is fixedly rotated on the pressing block 19, one end of the connecting rod 18 away from the pressing block 19 is fixedly rotated on the hollow column 6, and one end of the pressing block 19 facing the base cylinder 4 is fixedly connected with a ball head 20 in the same position; The base tube 4 is provided with a first annular ball groove 21 and a second annular ball groove 22 for sliding connection with the isotropic ball head 20, and the base tube 4 is also provided with a radial groove 23 for sliding connection with the isotropic ball head 20, and the two ends of the radial groove 23 are respectively connected with the first annular ball groove 21 and the second annular ball groove 22.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, when the hollow column 6 moves in the vertical direction, it can drive the multiple groups of connecting rods 18 arranged thereon to deflect synchronously, wherein, in the initial state, the pressure block 19 is located at the junction of the No. 1 annular ball groove 21 and the radial groove 23, and as the connecting rod 18 deflects, the pressure block 19 can drive the same-position ball head 20 to slide on the radial groove 23 until the same-position ball head 20 moves to the junction of the radial groove 23 and the No. 2 annular ball groove 22, thereby achieving the purpose of fixing the needle seat 2 at this position.

[0030] At the same time, when the hollow column 6 rotates in the horizontal direction, it can drive multiple groups of pressure blocks 19 to rotate synchronously through multiple groups of connecting rods 18 thereon. After the pressure block 19 completes the fixing process of the needle seat 2, as the hollow column 6 rotates horizontally, the isotropic ball head 20 arranged on the pressure block 19 can slide in the No. 2 annular ball groove 22 to avoid the existence of the base cylinder 4 causing motion interference in the rotation process of the pressure block 19. The opening of the No. 2 annular ball groove 22 can ensure that the pressure block 19 rotates synchronously with the hollow column 6, and can ensure the stability of the pressure block 19 during rotation.

[0031] Among them, multiple groups of pressure blocks 19 clamp and fix the needle seat 2 and drive the needle seat 2 to gradually separate from the cylinder 1 during the rotation process. Then, when the secondary clamping component releases the fixing effect on the needle seat 2, the needle seat 2 and the needle body 3 can eventually fall into the placement frame 34 along the cavity of the hollow column 6 under the action of gravity, so that the needle body 3 is driven to bend through the transverse bending component arranged at the placement frame 34 to hide the sharp needle tip, thereby reducing the risk of personnel being stabbed during the handling process, thereby reducing the risk of blood-borne diseases caused by needlestick injuries.

[0032] On the basis of the secondary clamping assembly embodiment, the separation assembly includes a rack 29 arranged on the base cylinder 4, and a groove body 2 for the rack 29 to be slidably connected is opened on the base cylinder 4, and the rack 29 is meshedly connected with a gear 30, and the gear 30 is driven to rotate by a motor and rotates on the box body with a fixed axis; The rack 29 is fixedly connected with a transverse rod 17, and one end of the transverse rod 17 away from the rack 29 is fixedly connected with a directional pin 15, and the hollow column 6 is provided with a spiral directional groove 16 for the directional pin 15 to be slidably connected; The outer circumference of the hollow column 6 is fixedly connected with a protrusion 7, and the hollow center tube 5 is provided with a vertical blocking groove 9 for the protrusion 7 to slide and connect in the vertical direction.

[0033] The separation assembly further comprises two groups of annular grooves 8 which are arranged on the hollow center tube 5 and are slidably connected to the protrusions 7 , and two ends of the vertical blocking groove 9 are respectively connected to one group of annular grooves 8 .

[0034] like Figure 1 , Figure 3 and Figure 8 As shown, when the gear 30 rotates, it can drive the rack 29 meshing with it to move in the vertical direction, wherein, when the rack 29 moves downward, it can drive the directional pin 15 fixed at the end of the transverse rod 17 to move downward through the transverse rod 17. At this time, the protrusion 7 is located at the junction of the vertical resistance groove 9 and a group of annular grooves 8 located above. As the transverse rod 17 moves downward, since the spiral directional groove 16 is not restricted by the hollow center tube 5, the hollow column 6 moves downward synchronously with the transverse rod 17, driving the protrusion 7 to slide on the vertical resistance groove 9.

[0035] At the same time, as the transverse rod 17 continues to move downward, the transverse rod 17 moves to the junction of the vertical resistance groove 9 and a group of annular grooves 8 located below, that is, moves to the end position of the vertical resistance groove 9. At this time, the hollow column 6 and the vertical resistance groove 9 cannot move downward synchronously with the transverse rod 17, and then as the transverse rod 17 continues to descend, it can drive the directional pin 15 to slide on the spiral directional groove 16, thereby driving the hollow center tube 5 to rotate in the horizontal direction.

[0036] Similarly, when the transverse rod 17 moves upward, its protrusion 7 first slides on the vertical blocking groove 9, and as the transverse rod 17 continues to move upward, it drives the hollow column 6 to rotate in the opposite direction. It should be noted that in actual use, the downward movement of the hollow column 6 can drive the primary clamping assembly and the secondary clamping assembly to clamp and fix the cylinder 1 and the needle seat 2 respectively, and subsequently, as the hollow column 6 rotates, the needle seat 2 is driven to rotate synchronously through multiple sets of connecting rods 18 and pressure blocks 19, so as to achieve the purpose of separating the cylinder 1 and the needle seat 2, and when the hollow column 6 moves upward, the fixation of the cylinder 1 and the needle seat 2 is released, and then under the action of gravity, the needle seat 2 carries the needle body 3 through the hollow column 6, the hollow ball head 10, the ball seat 11 and the bottom ring frame 12 to fall into the placement frame 34.

[0037] Based on the separation assembly embodiment, the transverse bending assembly includes a swing rod 36 that rotates on a placement frame 34 and rotates freely in the horizontal direction. The placement frame 34 includes an integrally formed right frame portion 341 and a left frame portion 342. The left frame portion 342 is communicated with the needle placement area. The right frame portion 341 is provided with a transverse plate 35, which is in sliding contact with the inner wall of the right frame portion 341, and a guide pin 37 is fixedly connected to one end of the swing rod 36 facing the transverse plate 35, and a guide groove 38 for the guide pin 37 to slide and connect is opened on the transverse plate 35.

[0038] A disc 31 is coaxially fixed on the gear 30 , and a plurality of groups of ratchets 32 arranged in a circular array are provided on the disc 31 , and an inner ratchet disc 33 transmission-connected to the rocker 36 is provided on the disc 31 , and the inner ratchet disc 33 rotates on a fixed axis on the box body, and the inner ratchet disc 33 is meshingly connected with the plurality of groups of ratchets 32 .

[0039] like Figure 2 , Figure 4 and Fig. 9 As shown, when the gear 30 rotates to drive the rack 29 and the transverse rod 17 to move downward, the disc 31 and the gear 30 rotate, but the pawl 32 set on the disc 31 does not engage with the inner ratchet disc 33, but bounces repeatedly with the rotation of the disc 31, so that the inner ratchet disc 33 does not rotate synchronously with the disc 31 at this time. When the gear 30 drives the rack 29 and the transverse rod 17 to move upward, the inner ratchet disc 33 can be driven to rotate synchronously through the disc 31 and multiple groups of pawls 32, wherein the inner ratchet disc 33 is connected to the rocker arm 36 by transmission, thereby driving the rocker arm 36 and the gear 30 to rotate synchronously.

[0040] At the same time, when the rack 29 and the transverse rod 17 move upward to release the fixation of the cylinder 1 and the needle seat 2, the needle seat 2 carries the needle body 3 and falls into the placement frame 34 after being released. At this time, the rocker arm 36 drives the transverse plate 35 to slide in the right frame portion 341 through the guide pin 37 and the guide groove 38, so that the transverse plate 35 can squeeze the needle body 3 in the placement frame 34 to drive the needle body 3 to bend under force, and the transverse plate 35 is in the horizontal terminal position, which can make the bent needle body 3 fall from the opening of the left frame portion 342 to the needle placement area.

[0041] It should be noted that a torsion spring is provided on the disc 31 to drive the pawl 32 to return to the initial deflection position. The torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure. In addition, the inner ratchet disc 33 and the rocker arm 36 can change the same-direction rotation position of the transmission shaft through the transmission between multiple sets of pulleys, and change the rotation direction of the transmission shaft by cooperating with the meshing relationship of multiple sets of conical teeth to achieve the purpose of synchronous rotation of the inner ratchet disc 33 and the rocker arm 36.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
