Description

Technical Field

[0001] The utility model relates to the technical field of strength detection, in particular to a denture strength detection device. Background Art

[0002] Dentures are artificial teeth that replace missing natural teeth, also known as false teeth. Currently, denture materials are mainly divided into metal, all-ceramic, resin, and polymer porcelain. Regardless of the material, denture strength performance has always been an important test item during use. For example, the Guangdong Medical Device Quality Supervision and Inspection Institute published "A Brief Discussion on the Necessity of Denture Hardness Testing and the Rationality of Test Subjects" in 2019. The article pointed out that hardness testing of finished dentures is a more reasonable way to demonstrate product performance.

[0003] The existing publication number CN220305071U discloses a denture all-round detection device, which is equipped with two sets of sensing modules and detection modules. During the process of the pressure sensor detecting the denture strength, since the pressure sensor is electrically connected to the digital display screen, the pressure sensor can transmit the denture strength data to the digital display screen to perform the denture strength detection operation. The detection operation is simple and convenient, and except for the electronic components that directly detect the denture strength, no additional electric drive device is required. However, during the process of the denture detection by this technology, the detection device is exposed to the outside. During the denture strength detection process, there is a situation of crushing and splashing, which will cause certain dangers and affect the subsequent cleaning work. For this reason, the utility model provides a denture strength detection device to improve this problem. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] like Figure 1-Figure 5 As shown, a denture strength testing device proposed in Example 1 of the present invention includes a working panel 1, a testing box 2 configured on the working panel 1, and a box door 3 and a control panel 4 configured on the testing box 2, wherein the control panel 4 is a control panel for displaying data during the strength testing process and starting the electrical components in the testing device proposed in this application. The small instrument of the testing device proposed in this application can be placed directly on the workbench through the working panel 1, wherein the bottom of the working panel 1 is provided with a rubber pad for contacting the workbench, and the testing box 2 is made of the aluminum alloy material just mentioned, with a hardness of about HB70-HB100. When the denture splashes during the testing process, it can be intercepted by the testing box 2, wherein the box door 3 is hinged to the testing box 2 by hinges, and the box door 3 is opened by flipping up. Observation windows 5 are installed on both sides of the testing box 2 for observing the situation inside the box, and the observation windows 5 are made of tempered glass;

[0024] A carrier plate 6 that slides with the working panel 1 is installed in the detection box 2. The carrier plate 6 enters and exits the detection box 2 through the box opening of the detection box 2 under the drive of the driving member 7. In this embodiment, the driving member 7 adopts a pneumatic push rod, which is directly installed on the detection box 2. A fixed plate 16 is installed on the carrier plate 6. The pneumatic push rod piston rod is connected to the fixed plate 16. The control circuit of the pneumatic push rod is connected to the control panel 4. The carrier plate 6 is driven in and out of the detection box 2 by the extension and contraction of the pneumatic push rod piston rod. A pressure sensor 9 is installed on the carrier plate 6, and a clamp 8 for clamping the denture is installed on the pressure sensor 9. A hydraulic push rod 17 is installed in the detection box 2, and the piston rod of the hydraulic push rod 17 is installed with a pressing piece 18. By moving the carrier plate 6 to the outside of the detection box 2, the denture is fixed based on the clamp 8, and then the carrier plate 6 is moved into the detection box 2 to complete the hardness test. The pressure sensor 9 and the hydraulic push rod 17 control circuits are both electrically connected to the control panel 4. The pressure sensor 9 proposed in this application is a piezoresistive sensor;

[0025] Based on the above-disclosed content, the hardness test of the present application is completed in the box, the fixture 8 completes the fixation of the denture, and the hydraulic push rod 17 pushes the pressing plate 18 to contact the denture. During this process, the pressure sensor 9 transmits the detection value to the control panel 4 for display until the denture is damaged, and the entire detection work is completed. During the whole process, since it is in the box, the flying denture is intercepted in the box and will not cause damage. It is also conducive to the subsequent cleaning work. Considering that the denture strength test is a spot check, not all dentures produced are tested. Therefore, the detection device proposed in this application is compactly designed and can be put into use when placed on a workbench.

[0026] As a preferred embodiment, the clamp 8 includes a positioning plate 801 arranged on the carrier plate 6, and a double-threaded screw 802 is rotatably installed on the positioning plate 801, and the double-threaded screw 802 is threadedly connected to two clamping blocks 803 with opposite movement directions, and the clamping blocks 803 slide in cooperation with the positioning plate 801. Considering that it is a sampling inspection and the overall inspection frequency is low, a manually operated clamp 8 structure is adopted. Considering that the shapes of the dentures are independent, because the finished dentures are designed based on each person's teeth, it is unreasonable to use a fixed structure to fix the dentures. Therefore, the present application adopts a traditional splint clamp 8, which relies on clamping friction to fix the denture. During operation, the double-threaded screw 802 is rotated to increase the distance between the two clamping blocks 803, and the denture is first clamped with a clamp, and the part of the denture that is not in contact with the clamp is facing the clamping block 803. The double-threaded screw 802 is rotated to drive the clamping blocks 803 to approach each other and contact the denture to complete the denture teeth, and then the clamp is released.

[0027] As a preferred embodiment, a mounting plate 12 is installed on the pressure sensor 9, and the mounting plate 12 is mounted on the carrier plate 6 by bolts. The clamp 8 is configured on the mounting plate 12, and the pressure sensor 9 is installed in a detachable manner to facilitate later replacement and maintenance.

[0028] As a preferred embodiment, the positioning plate 801 is provided with a mounting stud 14, the mounting plate 12 is provided with a mounting sleeve 13, the mounting stud 14 is threadedly connected to the mounting sleeve 13, and the installation of the clamp 8 is also detachable, which is convenient for the maintenance and replacement of the pressure sensor 9 and the maintenance and replacement of the clamp 8.

[0029] As a preferred embodiment, the working panel 1 is provided with two linear slide rails 10 distributed in parallel, a linear slider 11 is slidably installed on the linear slide rail 10, the linear slider 11 is installed on the carrier plate 6, a directional pulley 15 is installed on the carrier plate 6, the directional pulley 15 is in contact with the working panel 1, and the linear slide rail 10 and the linear slider 11 cooperate to realize the linear sliding of the carrier plate 6. However, considering the load-bearing capacity, the directional pulley 15 design is added, so that the overall stability of the carrier plate 6 is guaranteed both during the movement and during the strength test.

[0030] As a preferred embodiment, a connecting rod 19 is hinged between the linear slider 11 and the box door 3. With the cooperation of the connecting rod 19, when the carrier plate 6 moves toward the box door 3, the box door 3 flips up and opens, and when the carrier plate 6 moves into the box door 3, the box door 3 flips down and closes. The two are linked together, so there is no need to open and close the box door 3 separately.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
