Description

Technical Field

[0001] This utility model relates to the field of dental tools technology, and in particular to a bone powder cup capable of solid-liquid separation. Background Technology

[0002] Bone powder is typically made from natural bone minerals or synthetic biomaterials. Natural bone powder generally comes from animal or human bones that have undergone special processing to remove organic components; synthetic bone powder is made from materials such as hydroxyapatite. Materials used in bone grafting surgery are mainly divided into two categories: autologous bone powder and allogeneic bone powder. Autologous bone powder can better reduce the body's rejection reaction. In oral surgery, autologous bone powder made from one's own teeth can be used for implantation. Before use, the autologous bone powder is sterilized multiple times in a bone powder cup, and finally, the bone powder is separated from the sterilizing solution before clinical application.

[0003] A search revealed Chinese patent publication number CN221751483U, which discloses a bone meal container capable of solid-liquid separation. This container includes a cup body, a filter bowl, a pressure rod, and a rocker mechanism. The cup body has a bottom guide tube, and the filter bowl has a guide rod. The guide rod is movably positioned within the bottom guide tube. The pressure rod is movably positioned within the cup body. A clearance opening is provided on the side wall of the bottom guide tube. The rocker mechanism includes a bearing seat at the bottom of the cup body and a rocker. The rocker is rotatably mounted on the bearing seat. One end of the rocker extends from the clearance opening into the bottom guide tube and is positioned below the guide rod, while the other end is positioned below the pressure rod. The aforementioned patent has the following shortcomings: In existing bone meal cups, after sterilizing the bone meal, the bone meal easily flows out along with the sterilizing solution when poured out of the cup, and the bone meal also remains at the bottom of the cup, resulting in inefficient use and waste. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that bone powder is difficult to separate from disinfectant, which easily leads to waste of bone powder, and to propose a bone powder cup that can separate solid and liquid.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bone meal cup capable of solid-liquid separation includes an outer bone meal cup and an inner bone meal cup disposed within the outer bone meal cup. It also includes a driven rack plate disposed on one side of the outer wall of the inner bone meal cup. A gear is rotatably disposed within the outer bone meal cup, and an active rack plate is slidably connected to the inner wall of the outer bone meal cup. The gear meshes with both the driven rack plate and the active rack plate. When the active rack plate is driven downwards, the gear rotates, causing the driven rack plate to move upwards, which in turn moves the inner bone meal cup upwards.

[0007] Preferably, a guide block is fixedly connected to the inner wall of the bone meal outer cup, the driven rack plate and the active rack plate both pass through the guide block and are slidably connected to the guide block, a pressing block is fixedly connected to the top of the active rack plate, and a water outlet is provided on the bone meal outer cup.

[0008] Preferably, a U-shaped support frame is fixedly connected to the top of the guide block, and the gear is rotatably connected to the U-shaped support frame.

[0009] Preferably, a connecting block is detachably connected to the top of the driven rack plate, and the connecting block is fixedly connected to the bottom of the bone meal inner cup.

[0010] Preferably, a horizontal plate is fixedly connected to the bottom of the driven rack plate, and a round rod is fixedly connected to the top of the end of the horizontal plate away from the driven rack plate, and a first trapezoidal block is fixedly connected to the top of the round rod.

[0011] Preferably, a second trapezoidal block penetrates the surface of the round rod, the second trapezoidal block is slidably connected to the round rod, a first spring is sleeved on the surface of the round rod, one end of the first spring abuts against the second trapezoidal block, and the other end of the first spring is fixedly connected to the cross plate.

[0012] Preferably, a cylinder is fixedly connected to the inner left side of the bone meal outer cup, a sliding rod is slidably connected inside the cylinder, an arc-shaped limiting block is fixedly connected to the end of the sliding rod away from the cylinder, and a second spring is sleeved on the sliding rod, with the two ends of the second spring fixedly connected to the cylinder and the arc-shaped limiting block, respectively.

[0013] Preferably, the top of the inner bone meal cup has two sets of notches, the top of the outer bone meal cup is provided with a baffle, a retaining ring is fixedly connected to the baffle, and a retaining block corresponding to the notch is fixedly connected to the bottom of the baffle.

[0014] Compared with the prior art, this utility model provides a bone powder cup capable of solid-liquid separation, which has the following beneficial effects:

[0015] 1. This bone meal cup, capable of solid-liquid separation, rotates by pressing down on the active rack plate, which meshes with the gear. The rotation of the gear causes the driven rack plate to slide upwards, raising the inner bone meal cup to the same level as the outer bone meal cup. By fastening the retaining ring and baffle onto the outer bone meal cup and tilting the outer cup, disinfectant flows out through the gap between the baffle, retaining ring, and notch, thus quickly separating the bone meal from the disinfectant. Compared to the traditional method of directly pouring disinfectant out of the outer bone meal cup, this effectively reduces bone meal waste.

[0016] 2. This bone powder cup, capable of solid-liquid separation, rotates by pressing down on the pressing block, causing the active rack plate to mesh with the gear. The rotation of the gear causes the driven rack plate to slide upwards, raising the inner bone powder cup. Simultaneously, the first trapezoidal block on the horizontal plate abuts against the arc-shaped limiting block. The arc-shaped limiting block, via a sliding rod, compresses the first spring. Subsequently, the straight surface of the arc-shaped limiting block automatically engages with the straight surface of the first trapezoidal block under the restoring force of the first spring, thus limiting the position of the inner bone powder cup. This eliminates the need for manual pressing of the pressing block, enabling rapid separation of bone powder and disinfectant within the inner cup while simultaneously fixing its position, facilitating bone powder use by doctors.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Reference Figures 1-8 A bone powder cup capable of solid-liquid separation includes an outer bone powder cup 1 and an inner bone powder cup 2 disposed within the outer bone powder cup 1. It also includes a driven rack plate 3 disposed on one side of the outer wall of the inner bone powder cup 2. A gear 4 is rotatably disposed inside the outer bone powder cup 1, and an active rack plate 5 is slidably connected to the inner wall of the outer bone powder cup 1. The gear 4 meshes with both the driven rack plate 3 and the active rack plate 5. When the active rack plate 5 is driven downwards, the gear 4 rotates, causing the driven rack plate 3 to move upwards, which in turn moves the inner bone powder cup 2 upwards. When it is necessary to separate the bone powder from the disinfectant, simply press the active rack plate 3 downwards. The movable rack plate 5 meshes with the gear 4 to make it rotate. When the gear 4 rotates, it will drive the driven rack plate 3 to slide upward, which will cause the inner bone meal cup 2 to rise and be at the same level as the outer bone meal cup 1. As the inner bone meal cup 2 rises, the disinfectant gradually separates from the bone meal. When the top of the inner bone meal cup 2 is level with the top of the outer bone meal cup 1, the outer bone meal cup 1 is then tilted to separate the bone meal from the disinfectant in the inner bone meal cup 2. This can quickly separate the bone meal from the disinfectant. Compared with the traditional method of directly pouring the disinfectant out of the outer bone meal cup 1, it can effectively reduce the waste of bone meal.

[0029] A guide block 6 is fixedly connected to the inner wall of the bone meal outer cup 1. The driven rack plate 3 and the driving rack plate 5 both pass through the guide block 6 and are slidably connected to the guide block 6. A pressing block 17 is fixedly connected to the top of the driving rack plate 5. An outlet 18 is provided on the bone meal outer cup 1. During the up-and-down sliding process of the driving rack plate 5 and the driven rack plate 3, the guide block 6 can guide their sliding, so that the driving rack plate 5 and the driven rack plate 3 can move up and down stably and vertically.

[0030] A U-shaped support frame 7 is fixedly connected to the top of the guide block 6. The gear 4 is rotatably connected to the U-shaped support frame 7. The U-shaped support frame 7 can support the gear 4, so that the gear 4 can stably mesh with the driving rack plate 5 and the driven rack plate 3.

[0031] A connecting block 8 is detachably connected to the top of the driven rack plate 3. The connecting block 8 is fixedly connected to the bottom of the bone meal inner cup 2. The connecting block 8 is detachably connected to the driven rack plate 3. When the bone meal inner cup 2 needs to be cleaned later, the connecting block 8 can be detached from the driven rack plate 3 to remove the bone meal inner cup 2 for cleaning.

[0032] A horizontal plate 9 is fixedly connected to the bottom of the driven rack plate 3. A round rod 10 is fixedly connected to the top of the end of the horizontal plate 9 away from the driven rack plate 3. A first trapezoidal block 11 is fixedly connected to the top of the round rod 10. When the driving rack plate 5 presses down to make the driven rack plate 3 move upward, the horizontal plate 9 will be moved upward at the same time, which will drive the round rod 10 and the first trapezoidal block 11 on the surface of the round rod 10 to move upward.

[0033] A second trapezoidal block 12 passes through the surface of the round rod 10. The second trapezoidal block 12 is slidably connected to the round rod 10. A first spring 19 is sleeved on the surface of the round rod 10. One end of the first spring 19 abuts against the second trapezoidal block 12, and the other end of the first spring 19 is fixedly connected to the horizontal plate 9.

[0034] A cylinder 13 is fixedly connected to the inner left side of the outer bone powder cup 1. A sliding rod 14 is slidably connected inside the cylinder 13. An arc-shaped limiting block 15 is fixedly connected to the end of the sliding rod 14 away from the cylinder 13. A second spring 16 is sleeved on the sliding rod 14. The two ends of the second spring 16 are fixedly connected to the cylinder 13 and the arc-shaped limiting block 15, respectively. During the upward movement of the first trapezoidal block 11, the first trapezoidal block 11 abuts against the arc-shaped limiting block 15, causing the arc-shaped limiting block 15 to squeeze the first spring 19 through the sliding rod 14. Subsequently, the straight surface of the arc-shaped limiting block 15 will automatically fit and lock against the straight surface of the first trapezoidal block 11 under the restoring force of the first spring 19, thus limiting the position of the inner bone powder cup 2. There is no need to manually continue pressing the pressing block 17, which is convenient for doctors to use bone powder. When it is necessary to continue disinfecting the bone powder with disinfectant, simply press down on the pressing block 17 again to make the active rack plate 5 continue downward, driving the driven rack plate 3 to continue upward a certain distance. This will cause the round rod 10 on the horizontal plate 9 and the first trapezoidal block 11 to move upward, so that the second trapezoidal block 12 contacts the arc surface of the arc-shaped limiting block 15 until it disengages from the second trapezoidal block 12. At the same time, the second trapezoidal block 12 presses down on the second spring 16, and the second spring 16 then automatically pops the second trapezoidal block 12 upward, so that the second trapezoidal block 12 and the first trapezoidal block 11 form a smooth arc-shaped sphere. Then, pull the pressing block 17 upward to disengage the first trapezoidal block 11 from the arc-shaped limiting block 15, allowing the inner bone powder cup 2 to slide back into the outer bone powder cup 1 for disinfection with disinfectant.

[0035] The inner bone meal cup 2 has two sets of notches 20 at the top, and the outer bone meal cup 1 has a baffle 21 at the top. A retaining ring 22 is fixedly connected to the baffle 21, and a retaining block 23 corresponding to the notch 20 is fixedly connected to the bottom of the baffle 21. The baffle 21 is fastened to the outer bone meal cup 1 by the retaining ring 22. When the inner bone meal cup 2 slides upward to the top, the notch 20 of the inner bone meal cup 2 is blocked by the retaining block 23 at the bottom of the baffle 21. Then, the operator tilts the outer bone meal cup 1 to allow the disinfectant to flow out through the gap between the baffle 21 and the retaining block 23 and the notch 20, thereby avoiding waste of bone meal during the separation of bone meal from disinfectant.

[0036] It should be noted that the outer cup 1 of bone meal is 4 cm high and 5 cm wide, and the inner cup 2 of bone meal is 2 cm deep.

[0037] In this invention, when it is necessary to separate bone powder from disinfectant, pressing down on the pressing block 17 causes the active rack plate 5 to mesh with the gear 4 and rotate. When the gear 4 rotates, it causes the driven rack plate 3 to slide upward, which in turn causes the inner cup of bone powder 2 to rise. At the same time, the first trapezoidal block 11 on the horizontal plate 9 abuts against the arc surface of the arc-shaped limiting block 15. The arc-shaped limiting block 15 compresses the first spring 19 through the sliding rod 14. Subsequently, the straight part of the arc-shaped limiting block 15 will press against the first spring. Under the restoring force of 19, it automatically fits and locks against the straight surface of the first trapezoidal block 11, thereby limiting the position of the inner bone powder cup 2. At this time, the top of the inner bone powder cup 2 and the top of the outer bone powder cup 1 are on the same plane. Then, the retaining ring 22 drives the baffle 21 to lock onto the outer bone powder cup 1. After that, simply tilt the outer bone powder cup 1 to allow the disinfectant to flow out from the outlet 18 through the gap between the baffle 21, the retaining block 23 and the notch 20, so that the bone powder in the inner bone powder cup 2 can quickly react with the disinfectant. While quickly separating, it can also fix the position of the inner bone powder cup 2, making it convenient for doctors to use bone powder. Compared with the traditional method of directly pouring out disinfectant from the outer bone powder cup 1, it can effectively reduce the waste of bone powder. When it is necessary to continue disinfecting the bone powder with disinfectant, simply press down on the pressing block 17 again, so that the active rack plate 5 continues to move downward, driving the driven rack plate 3 to move upward a certain distance. This will cause the round rod 10 on the horizontal plate 9 and the first trapezoidal block 11 to move upward, so that the second trapezoidal block 12 abuts against the arc surface of the arc-shaped limiting block 15 until it separates from the second trapezoidal block 12. At the same time, the second trapezoidal block 12 presses down on the second spring 16, and the second spring 16 then automatically pops the second trapezoidal block 12 upward, so that the second trapezoidal block 12 and the first trapezoidal block 11 form a smooth arc-shaped sphere. Then, pull up the pressing block 17 to separate the first trapezoidal block 11 from the arc-shaped limiting block 15, so that the inner bone powder cup 2 can re-enter the outer bone powder cup 1 for disinfection with disinfectant.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
