[0021] A denture strength detection device comprises a base 1, wherein symmetrical vertical plates 2 are provided on the left and right sides of the upper end surface of the base 1, a hydraulic cylinder 3 is provided on the upper end surface of the vertical plates 2, a connecting plate 4 is provided between the telescopic shafts of the two hydraulic cylinders 3, a strength detection rod 5 is suspended on the connecting plate 4, a mounting seat 6 is rotatably mounted at the center of the base 1, a plurality of circumferentially arranged clamping assemblies are provided on the upper end surface of the mounting seat 6, the strength detection rod 5 is located directly above the clamping assembly, a telescopic cylinder 7 is provided on the side surface of one of the vertical plates 2, and a damage detection component 8 is connected to the telescopic shaft of the telescopic cylinder 7.

[0022] The mounting seat 2 is a cylinder, and the bottom surface of the mounting seat 2 is provided with a connecting shaft coaxial therewith, and the connecting shaft is inserted into the base 1 and is rotatably connected to the base 1 through a bearing. In this embodiment, the clamping assembly is provided with four and is evenly arranged in a circle with the axis of the mounting seat 2 as the center and is installed on the upper end surface of the mounting seat 2. At the same time, a ball 19 can be arranged between the lower end surface of the mounting seat 2 and the upper end surface of the base 1. Symmetrical annular grooves are provided on the lower end surface of the mounting seat 2 and the upper end surface of the base 1. A plurality of balls 19 are clamped between the two annular grooves. When the mounting seat 2 rotates, the balls 19 The sliding friction between the mounting seat 2 and the base 1 can be converted into rolling friction, which is convenient for the rotation of the mounting seat 2. At the same time, when the strength detection rod 5 is pressed down, the stability of the mounting seat 2 in the vertical direction can also be guaranteed through the support of the ball 19; when the strength detection rod 5 is pressed down to perform pressure strength detection on the denture on one of the clamping components, the other denture that has been strength tested can be tested through the damage detection component 8 to check whether it has cracks, notches and other damages under the specified pressure, which is equivalent to being able to test multiple dentures at the same time, thereby improving the detection efficiency of the dentures.

[0023] The vertical movement of the connecting plate 4 and the strength detection rod 5 is achieved by the synchronous extension and retraction of the two hydraulic cylinders 3. In this embodiment, the synchronous movement of the two hydraulic cylinders 3 can provide greater power and pressure for the downward pressing of the strength detection rod 5, which is convenient for meeting the requirements of the denture pressure strength test. A pressure sensor is built in the strength test rod 5, and a display screen for displaying real-time pressure is connected through a line. The display screen is installed on the connecting plate 4. The real-time pressure applied by the strength detection rod 5 is convenient to observe through the pressure sensor and the display screen, ensuring that it can be applied to the specified pressure range.

[0024] A protective cover 17 is sleeved on the middle part of the strength detection rod 5, and the protective cover 17 is a hollow cylinder with an unsealed bottom. The end of the strength detection rod 5 extends from top to bottom along the axis of the protective cover 17 into the inner cavity of the protective cover 17, and a limit plate 18 is also provided in the middle part of the strength detection rod 5. The limit plate 18 is located in the inner cavity of the protective cover 18. When the strength detection rod 5 moves upward, the limit plate 18 fits with the inner wall of the upper end surface of the protective cover 17 and moves upward with the upward movement of the strength detection rod 5. When the strength detection rod 5 moves downward, the protective cover 17 will be placed on the upper end surface of the limit plate 18 and move downward with the limit plate 18. The safety of the device can be improved by the protective cover 17. Specifically, when the protective cover 1 When the clamping assembly is rotated to the bottom facing the protective cover 17, the protective cover 17 and the strength detection rod 5 move downward. Before the lower end of the strength detection rod 5 contacts the denture, the lower end of the protective cover 17 first fits with the upper end surface of the mounting plate 2, and the entire clamping assembly and the denture buckle cover are fastened. Then the strength detection rod 5 continues to move downward until it is pressed down on the denture to perform a pressure strength test on the denture. If the denture is unqualified, for example, it cannot withstand the specified pressure test, the denture may break and splash under the heavy pressure. At this time, the protective cover 17 can be used to prevent debris from splashing around and injuring the operator, thereby improving the safety of the device.

[0025] The protective cover 17 can be made of a transparent plastic material. Through the transparent protective cover 17 , it is easy to observe the strength detection rod 5 and to adjust the mounting seat 2 so that the clamping assembly can be directly opposite to the strength detection rod 5 .

[0026] The limit plate 18 can be installed on the strength detection rod 5 by means of a threaded connection. An external thread is provided in the middle of the strength detection rod 5, and an internal thread matching the internal thread is provided at the central inner hole of the limit plate 18. The strength detection rod 5 is first inserted into the protective cover 17 and then the limit plate 18 is screwed in, which facilitates the installation of the limit plate 18 and makes it easier to replace the protective cover 17.

[0027] Specifically, in this embodiment, the clamping assembly includes a placement table 9 and two clamping plates 10 arranged opposite to each other. The placement table 9 is fixedly mounted on the upper end surface of the mounting seat 6. The two clamping plates 10 are vertically mounted on the upper end surface of the placement table 9. A threaded hole is provided at the center of one of the clamping plates 10. A screw rod 12 is threadedly connected in the threaded hole. One end of the screw rod 12 is located between the two clamping plates 10, and a pressure plate 13 is provided at the end of the screw rod 12. When fixing the denture, the denture is first placed between the two clamping plates 10, and then the screw rod 12 is tightened to allow the pressure plate 13 to move inward and fit with the end surface of the denture, thereby fixing the denture between the pressure plate 13 and the clamping plate 10. At the same time, a rubber layer 11 is provided on the end face of the pressure plate 13, and a rubber layer 11 is also provided on the opposite face of the other splint 10. The rubber material has a certain toughness. Therefore, when the denture is clamped, the rubber layer 11 adheres to the side of the denture and is squeezed and deformed. When the rubber layer 11 is deformed, a rebound force is generated, and the denture can be further clamped by its rebound force. On the other hand, the rubber layer 11 can also increase the friction coefficient between the denture and the friction between the denture and the denture, which can further ensure the stability of the denture after clamping.

[0028] The pressure plate 13 and the screw rod 12 can be detachably connected by means of a threaded connection. A thread groove is provided at the center of the end face of the pressure plate 13, which is adapted to the threaded rod 12, and the rotation direction of the internal thread on the thread groove is the same as the rotation direction of the internal thread of the threaded hole of the clamp plate 10. That is to say, when the threaded rod 12 is rotated to allow the pressure plate 13 to move inward to clamp the denture, the threaded rod 12 also rotates in the direction of tightening the pressure plate 13.

[0029] The outer wall of the mounting seat 6 is covered with a first transmission gear 15, the upper end surface of the base 1 is installed with a driving motor 14, the driving shaft of the driving motor 14 is connected with a second transmission gear 16, and the first transmission gear 15 is adapted to mesh with the second transmission gear 16. The driving motor 14 provides power for the rotation of the mounting seat 6, and when the mounting seat 6 does not need to rotate, the self-locking of the driving motor 14 can also prevent the mounting seat 6 from rotating.

[0030] Specifically, in the present embodiment, the damage detection component 8 is a high-intensity flashlight, and the damage detection component 8 and the splint 10 are located at the same height. When the pressure strength test of the denture is completed, the high-intensity flashlight is fitted to the side of the denture through the extension and retraction of the telescopic cylinder 7. The denture becomes transparent due to the irradiation of strong light. At this time, the operator and inspector can observe whether there are cracks on the denture, whether there are gaps on the surface, etc. through the transparent denture, so as to judge whether the denture is qualified and has passed the pressure strength test.

[0031] The working principle of this utility model:

[0032] When inspecting dentures, four clamping assemblies can be used to simultaneously inspect multiple dentures. The specific inspection process is as follows: the denture located on the left end face clamping assembly of the mounting seat 6 is subjected to strength inspection through the strength inspection rod 5, and the denture on the front end face clamping assembly of the mounting seat 6 is subjected to damage inspection through the damage inspection component 8. The denture on the right end face clamping assembly of the mounting seat 1 is the denture after inspection. When the other two dentures are being inspected, the denture on the clamping assembly can be removed. The denture on the rear end face clamping assembly of the mounting seat 6 is the denture waiting to be inspected. When the other two dentures are being inspected, the denture is installed on the clamping assembly. After each denture is inspected, the mounting seat 6 rotates once, so that uninterrupted inspection of the denture can be achieved, thereby improving inspection efficiency.
