Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0030] It should be noted that in the description of this application, the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application 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 application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0033] This embodiment provides a centrifugation testing device, see reference. Figures 1-7As shown, the centrifuge includes a centrifuge body 1, which includes a base 2 and a motor 3 mounted on the base 2. The output shaft 31 of the motor 3 passes through a bearing seat 21 and extends into a transmission cavity 22 to be connected to a rotating shaft 4. The upper end face of the rotating shaft 4 is connected to the center of a rotating plate 5. A bushing 41 is provided on the outside of the rotating shaft 4. The bottom end of the bushing 41 is connected to the upper part of the transmission cavity 22. A placement basket 51 is installed on one end of the rotating plate 5. The bottom end face of the placement basket 51 is provided with a mounting hole 511. An insertion hole 52 is provided on one end of the rotating plate 5. An insertion rod 53 is provided on the bottom end of the placement basket 51 and is inserted into the insertion hole 52.

[0034] In the above embodiment, a base 2 is provided at the lower part of the centrifuge body 1. The base 2 is used to stably support the centrifuge body 1, and the centrifuge body 1 can be connected to the ground through the base 2, providing mounting points for the components of the centrifuge body 1, which is beneficial to improving the stability of the centrifuge body 1 during installation and operation. Furthermore, a motor 3 is provided above the base 2, and the output shaft 31 of the motor 3 passes through the bearing seat 21 and extends into the transmission cavity 22 to be connected to the rotating shaft 4. The bearing seat 21 and the transmission cavity 22 are respectively connected and arranged on the upper part of the base 2. The bearing seat 21 is used to support the output shaft 31 in the vertical direction, so that the output shaft 31 remains horizontal when the motor 3 drives the output shaft 31 to rotate, preventing the output shaft 31 from shifting downwards due to its own weight, which is beneficial to improving the stability of the output shaft 31 during rotation. Figure 7 As shown, one end of the output shaft 31 extending into the transmission cavity 22 is connected to the bottom end of the rotating shaft 4 via a bevel gear transmission. That is, the horizontal rotation of the output shaft 31 is converted into the vertical rotation of the rotating shaft 4 through the bevel gear transmission. A bushing 41 is provided on the outside of the rotating shaft 4, and the rotating shaft 4 is nested in the bushing 41. The rotating shaft 4 can rotate within the bushing 41. The bushing 41 is used to maintain the vertical position of the rotating shaft 4 to prevent the rotating shaft 4 from moving downward during rotation. The upper end face of the rotating shaft 4 is aligned with the center of the elongated rotating plate 5. Connected to the rotating plate 5, a placement basket 51 is installed at one end for placing components to be tested under centrifugal force. The bottom surface of the placement basket 51 has a mounting hole 511, which can be a threaded mounting hole or a slot, for fixing the component under test to the bottom of the placement basket 51. Additionally, one end of the rotating plate 5 has an insertion hole 52, and an insertion rod 53 is connected to the bottom of the placement basket 51. The insertion rod 53 is inserted into the insertion hole 52, thus fixing the placement basket 51 to the rotating plate 5. In summary, the output shaft 31 is driven to rotate by the motor 3. The output shaft 31 passes through the bearing seat 21 and extends into the transmission cavity 22, connecting with the rotating shaft 4. The rotating shaft 4 can drive the rotating plate 5 to rotate. The placement basket 51, used to hold the component under test, is connected to one end of the rotating plate 5. When the rotating plate 5 rotates, it causes the placement basket 51 to perform circular motion, thereby generating centrifugal force to verify the structural integrity or functional reliability of the component in the placement basket 51 under centrifugal force.

[0035] In one embodiment of this application, see reference Figure 3 and Figure 4 As shown, a through hole is provided on the bottom side wall of the insertion rod 53, and a safety bolt 531 is inserted into the through hole. A nut is fitted at the tail end of the safety bolt 531.

[0036] In the above embodiment, the insertion rod 53 at the bottom of the placement basket 51 is inserted through the insertion hole 52 on the rotating plate 5. The bottom end of the insertion rod 53 passes through the insertion hole 52, and a through hole is opened on the side wall of the bottom end of the insertion rod 53. A safety bolt 531 is inserted into the through hole to prevent the insertion rod 53 from separating from the insertion hole 52 due to the centrifugal force generated when the rotating plate 5 rotates. That is, the placement basket 51 separates from the rotating plate 5, which would cause the components inside the placement basket 51 to collide and be damaged, or the detached placement basket 51 to injure the equipment and personnel. The safety bolt 531 is used to improve the safety of fixing the placement basket 51, and a nut is fitted at the tail end of the safety bolt 531 to prevent the safety bolt 531 from coming out of the through hole.

[0037] In one embodiment of this application, see [reference] Figure 5 As shown, the rotating plate 5 has a plurality of insertion holes 52 evenly arranged on it.

[0038] In the above embodiments, multiple insertion holes 52 can be used to fix multiple placement baskets 51. The rotation radius of the placement baskets 51 in different insertion holes 52 is different, and the centrifugal force they are subjected to is different. This can be used to test the effects of the same batch of components on different magnitudes of centrifugal force. The test results can be compared and referenced, which is beneficial to improving the practicality and accuracy of the test.

[0039] In one embodiment of this application, see reference Figure 3 As shown, a pull strap 512 is connected inside the placement basket 51.

[0040] In the above embodiments, on the one hand, the pull strap 512 can be used to further bind and fix the components fixed in the mounting holes 511 inside the placement basket 51 to improve the stability of the components during centrifugal testing. On the other hand, for some components, such as integrally molded electrical components, which cannot be fixed through the mounting holes 511, they can be fixed in the placement basket 51 by binding with the pull strap 512, which is beneficial to improving the adaptability of the placement basket 51 to the fixing of test components.

[0041] In one embodiment of this application, see reference Figure 6 As shown, a fixing post 54 is provided on the upper surface of the other end of the rotating plate 5.

[0042] In the above embodiment, the fixing column 54 can be used to install a counterweight block on the other end of the rotating plate 5 to balance the weight of the placement basket 51 and the components inside the placement basket 51 set at one end of the rotating plate 5, so that the weight at both ends of the rotating plate 5 is balanced, which is beneficial to improving the stability of the rotating plate 5 when it rotates. Optionally, the fixing column 54 is a threaded column that works with a fixing nut to fix the counterweight block.

[0043] In one embodiment of this application, see reference Figure 1 As shown, an annular protective wall 6 is provided on the outside of the centrifuge body 1, and a camera 61 is installed on the upper end of the protective wall 6.

[0044] In the above embodiment, when the centrifuge body 1 is operating, the rotating plate 5 will rotate. The components on the rotating plate 5 will loosen and detach under the action of centrifugal force. The detached parts will be thrown out, which may easily injure the equipment or personnel outside the device. The ring-shaped protective wall 6 is set to protect the outer space of the device, which is beneficial to improving the safety of the device operation. Furthermore, the protective wall 6 is equipped with a movable door for personnel to enter and exit. When the device is running, the movable door is in the closed state. A camera 61 is installed at the upper end of the protective wall 6 for observation and recording of the situation inside the protective wall 6 during centrifugation test.

[0045] In one embodiment of this application, see reference Figure 6 As shown, a data logger 7 is provided in the middle of the rotating plate 5.

[0046] In the above embodiment, the data logger 7 is positioned in the middle of the rotating plate 5 to minimize the centrifugal force on it. The data logger 7 is equipped with a data interface for connecting to the tested components via a data cable, and can record the real-time status of the components during the centrifugation experiment, thus improving the accuracy and reliability of the test. The data logger 7 can be a multi-channel recorder or a PC recorder from the prior art.

[0047] In actual use, the centrifuge body 1 has a base 2 at its lower part, and a motor 3 is installed on the upper part of the base 2. The output shaft 31 of the motor 3 passes through the bearing seat 21 and extends into the transmission cavity 22 to be connected to the rotating shaft 4. A placement basket 51 is installed at one end of the rotating plate 5 for placing components to be centrifuged. The bottom surface of the placement basket 51 has a mounting hole 511, which can be a threaded mounting hole 511 or a slot, for fixing the components to be tested at the bottom of the placement basket 51. In addition, a plug is provided at one end of the rotating plate 5. Hole 52, the bottom end of the placement basket 51 is connected to the insertion rod 53, the insertion rod 53 is inserted into the insertion hole 52, so that the placement basket 51 is inserted and fixed to the rotating plate 5. The rotating plate 5 is driven to rotate by the rotating shaft 4. When the rotating plate 5 rotates, it drives the placement basket 51 to perform circular motion, thereby generating centrifugal force. After the test, the structural changes of the components can be observed by comparison. For electronic components, a test circuit can be connected to verify whether they are operating normally, thereby verifying the structural integrity or functional reliability of the components in the placement basket 51 under the centrifugal force environment.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
