Description

Technical Field

[0001] This utility model relates to the field of blood type testing, and more specifically, to a polygonal blood type card centrifuge turntable. Background Technology

[0002] In the field of medical testing, blood typing is a fundamental and crucial task. Currently, semi-automatic blood typing equipment on the market only offers incubation and centrifugation functions, with centrifuge discs typically employing a longitudinally concentric arrangement of blood typing cards. This traditional design limits the centrifuge discs to only the centrifugation function of the blood typing cards, resulting in numerous structural and layout limitations. For example, the fixed installation layout of the blood typing card adapter lacks expansion structures and installation space, making it difficult to connect other equipment. Taking the requirement of photographing the centrifuged blood typing cards for electronic storage and traceability as an example, existing centrifuge discs cannot easily accommodate cameras for taking pictures, restricting the expansion of equipment functions and the convenience of test data management, failing to meet the requirements of modern medical testing for accurate data recording, efficient management, and traceability.

[0003] How to invent a polygonal blood type card centrifuge turntable to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a polygonal blood type card centrifuge turntable, which aims to improve the existing centrifuge turntable structure and blood type card adapter installation layout, which lack external expansion structure and installation space for connecting other devices, resulting in certain limitations in use.

[0005] This utility model is implemented as follows: A polygonal blood type card centrifuge turntable includes a polygonal turntable body. Each side of the upper surface of the polygonal turntable body has an adapter slot.

[0009] In a preferred embodiment of this utility model, the adjusting limit mechanism is an adjusting screw. The adjusting screw is threadedly connected to a threaded hole on the top surface of the corresponding slider. The bottom end of the adjusting screw is rotatably connected to the inner wall of the bottom of the corresponding lifting adjusting slide. The top end of each adjusting screw is rotatably connected to a through hole on the inner wall of the top of the corresponding lifting adjusting slide and extends through the through hole to the outside of the lifting adjusting slide and is fixedly connected to a knob.

[0010] In a preferred embodiment of this utility model, the angle adjustment mechanism includes a hinge rod, one end of which is fixedly connected to a rotating shaft and rotatably connected to the end of an extension rod away from the slider via the rotating shaft. One end of the rotating shaft is connected to an angle limiting mechanism, and the equipment mounting plate is fixedly connected to the other end of the hinge rod.

[0011] In a preferred embodiment of this utility model, the angle limiting mechanism includes a gear fixedly sleeved on one end of a rotating shaft and a side plate integrally formed on one side surface of an extension rod.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 7 This utility model provides a technical solution: a polygonal blood type card centrifuge turntable, including a polygonal turntable body 1. Each side of the upper surface of the polygonal turntable body 1 has an adapter slot 101. A corresponding bracket positioning groove 102 is provided inside each adapter slot 101 on the upper surface of the polygonal turntable body 1. An expansion device mounting bracket 2 can be detachably connected to each bracket positioning groove 102. Each expansion device mounting bracket 2 includes a base 201, which is detachably connected to the corresponding bracket positioning groove 102. A vertical plate 203 is integrally formed on the upper surface of the base 201. A lifting adjustment groove 204 is formed through one side surface of the vertical plate 203. A slider 205 is slidably connected within the lifting adjustment groove 204. The slider 205 is connected to an adjustment limit mechanism. An extension rod 208 is provided on one side surface of the slider 205. The end of the extension rod 208 is connected to a device mounting plate 216 via an angle adjustment mechanism.

[0025] It should be noted that the inner wall of each adapter slot 101 is provided with a snap-fit ​​structure that mates with the insertion end of the blood type card adapter 3. This snap-fit ​​structure is consistent with the existing blood type card centrifuge slots and adopts a standardized slot. After the blood type card adapter 3 is inserted into the corresponding adapter slot 101, it can achieve stable positioning and ensure the stability of the connection between the blood type card adapter 3 and the blood type card 4 and the polygonal turntable body 1 during centrifugation.

[0026] Please see Figures 1 to 4 The polygonal turntable body 1 is a regular polygon with an even number of sides.

[0027] The design ensures the balance and stability of the polygonal turntable body 1 during rotation, while also facilitating the even distribution of blood type card adapters and the symmetrical installation of external devices. In practice, the polygonal turntable body 1 can be a regular hexagon, a regular octagon, etc. Taking a regular hexagon as an example, each side has equal length and equal interior angles. During high-speed rotation of the centrifuge, the centrifugal force on each side is relatively balanced, effectively reducing turntable vibration and wear. Furthermore, the even-numbered sides facilitate the installation of identical external devices on opposite sides, such as front and rear cameras on opposite sides, enabling comprehensive photography of the blood type cards. This improves the stability of the centrifuge turntable during operation, ensures the accuracy of centrifugation operations, and facilitates the rational layout of external devices, enhancing the effectiveness and efficiency of extended functions such as photography.

[0028] Furthermore, each base 201 surface and the bottom inner wall of the corresponding bracket positioning groove 102 are provided with assembly holes 202 for inserting fasteners.

[0029] A stable connection is achieved between the expansion equipment mounting bracket 2 and the polygonal turntable body 1. Fasteners such as bolts and screws can be used. When installing the expansion equipment mounting bracket 2, pass the bolts or screws through the mounting holes 202 and then tighten them with nuts, or directly screw the screws into the corresponding screw holes to ensure that the base 201 is firmly fixed in the bracket positioning groove 102. The installation and disassembly process is simple and convenient, allowing users to easily replace or adjust the position of the expansion equipment mounting bracket 2 according to actual needs. At the same time, it ensures a firm connection; the expansion equipment mounting bracket 2 will not loosen or shift when the centrifuge rotates at high speed, ensuring the stable operation of the external equipment.

[0030] Please see Figures 4 to 7 Each lifting adjustment slide 204 and slider 205 has a corresponding isosceles trapezoidal structure in cross-section, and the side length of the lifting adjustment slide 204 and slider 205 near the corresponding adapter slot 101 is less than the side length near the axis of the polygonal turntable body 1.

[0031] Under the powerful centrifugal force generated by the high-speed rotation of a centrifuge, a conventional rectangular structure may not guarantee the stability of the slider 205. The isosceles trapezoidal structure, however, provides a larger and more rationally distributed contact area between the slider 205 and the lifting adjustment groove 204. When centrifugal force acts on the slider 205, the constraint force from the lifting adjustment groove 204 better balances the centrifugal force due to the isosceles trapezoidal structure. The longer side closer to the axis provides a more stable support base, making it difficult for the slider 205 to move independently outward under centrifugal force. The selection of suitable materials, such as high-strength metal alloys, enhances the strength and wear resistance of the structure, allowing it to maintain good performance even under long-term centrifugal force. This improves the stability of the slider 205's connection within the lifting adjustment groove 204, ensuring the normal operation of external equipment during high-speed centrifuge operation. This, in turn, ensures the reliability and accuracy of the entire centrifuge turntable expansion function, effectively preventing malfunctions of external equipment caused by slider 205 displacement, and improving the overall performance and practicality of the equipment.

[0032] Furthermore, the adjustment limit mechanism is an adjustment screw 206. The adjustment screw 206 is threadedly connected to a threaded hole on the top surface of the corresponding slider 205. The bottom end of the adjustment screw 206 is rotatably connected to the bottom inner wall of the corresponding lifting adjustment slide 204. The top end of each adjustment screw 206 is rotatably connected to a through hole on the top inner wall of the corresponding lifting adjustment slide 204 and extends through the through hole to the outside of the lifting adjustment slide 204 and is fixedly connected to a knob 207.

[0033] The user rotates knob 207, causing adjusting screw 206 to rotate. Due to the thread, slider 205 moves up and down within lifting adjustment groove 204. To ensure smooth adjustment, lubricating oil can be added to the connection between adjusting screw 206 and lifting adjustment groove 204. This provides a simple, intuitive, and precise height adjustment method, allowing users to easily adjust the height of external equipment according to actual needs, improving the equipment's operational convenience and applicability. Simultaneously, the self-locking characteristic of the threaded connection helps maintain a stable height against centrifugal force during centrifugation.

[0034] Furthermore, the angle adjustment mechanism includes a hinge rod 209, one end of which is fixedly connected to a rotating shaft and rotatably connected to the end of the extension rod 208 away from the slider 205. One end of the rotating shaft is connected to the angle limiting mechanism, and the equipment mounting plate 216 is fixedly connected to the other end of the hinge rod 209.

[0035] The hinge rod 209 has a pivot at one end that is rotatably connected to the extension rod 208, and the equipment mounting plate 216 is fixed to the other end of the hinge rod 209. When the angle needs to be adjusted, the hinge rod 209 can be rotated by external force, causing the equipment mounting plate 216 to rotate around the pivot. To ensure the flexibility of angle adjustment, a bearing connection can be used at the joint between the pivot and the extension rod 208. This allows the external equipment to flexibly adjust its angle according to actual working needs, improving the adaptability of the equipment. For example, when taking pictures of blood type cards, the camera angle can be better adjusted to obtain clear images.

[0036] Furthermore, the angle limiting mechanism includes a gear 210 fixedly sleeved on one end of the rotating shaft and a side plate 211 integrally formed on one side surface of the extension rod 208. A sliding groove 212 is provided on the upper surface of the side plate 211, and a rack 213 is slidably connected in the sliding groove 212. The rack 213 meshes with the gear 210. A plurality of evenly distributed limiting holes 214 are provided on one side surface of the rack 213 along its extension direction. A threaded hole is provided through one side surface of one end of the side plate 211, and a limiting screw 215 is inserted into the threaded hole and one of the corresponding limiting holes 214.

[0037] Gear 210 is fixedly sleeved on one end of the rotating shaft, and rack 213 slides in the groove 212 and meshes with gear 210. When the angle needs to be adjusted, first loosen the limiting screw 215, move rack 213, and the rotating shaft will rotate through the meshing of rack 213 and gear 210, thereby adjusting the angle of hinge rod 209. After adjusting to the appropriate angle, insert limiting screw 215 into the corresponding limiting hole 214 to fix the position of rack 213, thereby limiting the rotation of hinge rod 209. To ensure the accuracy of angle adjustment, the limiting holes 214 need to be evenly distributed, and the tooth profile accuracy of rack 213 and gear 210 needs to be high, realizing multiple specific angle limiting methods to ensure that the external equipment can work stably after the angle is adjusted, avoiding the impact of angle changes on the working effect, and improving the reliability and stability of the equipment.

[0038] Furthermore, the upper surface of the equipment mounting plate 216 has two mounting slots 217 for mounting external equipment, and each mounting slot 217 has several connection holes 218 on its bottom inner wall.

[0039] The size and shape of the mounting slot 217 can be designed according to the shape of the external device. The connecting hole 218 is used to fix the external device to the equipment mounting plate 216 using bolts, screws, or other connectors. For example, when installing a camera, the bottom of the camera can be aligned with the mounting slot 217, and then the camera can be firmly fixed using screws through the connecting hole 218. This provides a standardized interface for the installation of external devices, improving the convenience and versatility of installation, allowing different types of external devices to be easily installed on the equipment mounting plate 216, further expanding the functionality of the centrifuge turntable.

[0040] Working principle: The polygonal turntable body 1 is installed at the output shaft end of the centrifuge drive unit. The blood type card 4 is inserted into the blood type card adapter 3. Because the inner wall of the adapter slot 101 has a standardized snap-fit ​​structure that matches the insertion end of the blood type card adapter 3, the blood type card adapter 3 can be stably limited after being inserted into the corresponding adapter slot 101, ensuring a stable connection between the blood type card adapter 3, the blood type card 4, and the polygonal turntable body 1 during centrifugation. The polygonal turntable body 1 is a regular polygon with an even number of sides, which can maintain balance and stability during rotation, facilitating the even distribution of blood type card adapters and symmetrical installation of external equipment. The expansion equipment mounting bracket 2 is fixed to the polygonal turntable body 1 with bolts or screws through the mounting holes 202 of the base 201 and the bracket positioning groove 102, making it convenient for users to replace or adjust according to their needs. For external cameras and photoelectric sensors, they can be installed on the equipment mounting plate 216, and fixed with connectors through the mounting slot 217 and the connection hole 218 during installation. To adjust the height, rotate knob 207 to drive adjusting screw 206, causing slider 205 to move up and down within the isosceles trapezoidal lifting adjustment groove 204. This structure ensures the stability of slider 205 under centrifugal force, preventing outward displacement. To adjust the angle, loosen limit screw 215, move rack 213, and through meshing with gear 210, drive hinge rod 209 to rotate around the axis, thereby adjusting the angle of equipment mounting plate 216. After adjustment, insert limit screw 215 to fix it, achieving multi-angle limiting. Through the above adjustment methods, the position and angle of external camera and photoelectric sensor can be flexibly adjusted. During centrifuge operation, the camera can take pictures of blood type cards for storage, and the photoelectric sensor can detect blood type cards, improving the functionality and applicability of the centrifuge turntable.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
