[0002] Dental diaphragms are polymer materials used for bracketless orthodontic correction. They are usually 0.6mm to 1.5mm thick, 120mm or 125mm in diameter, or 125mm in length. Their tensile elastic modulus is 700MPa to 3000Mpa, and color consistency is a basic requirement for the product. During the inspection of dental diaphragms, a desktop spectrophotometer is used to perform a transmission color test on the formed sheet-like film discs or squares to determine the color difference between the sample film and the standard sample. However, due to the thickness and modulus of the diaphragm itself, the initial sample may be slightly warped, which makes it easy for the film to leak light when placed in different test areas, causing detection deviations.
[0003] A simple improvement method is to have the tester press the sample tightly and leave a test light channel, but this introduces the human factor, which increases labor costs and affects the test quality due to the tester not pressing tightly enough. In addition, some testing equipment is equipped with a clamping fixture mechanism, but during the test, the insertion and movement of the diaphragm are restricted, and there is also a potential risk of scratching the membrane surface, which affects the test results.

[0023] refer to Figures 1 to 3 A sample fixing device for colorimetric measurement of a dental film according to a preferred embodiment of the utility model will be described in detail below, wherein the sample fixing device for colorimetric measurement of a dental film comprises an L-shaped mounting base 10 and a spring clamping mechanism 20, wherein the L-shaped mounting base 10 comprises a horizontal base 11 and a clamping base plate 12 vertically connected to one end of the horizontal base 11, wherein the horizontal base 11 is used to be mounted on the base of the instrument to be tested area and fixed by two M4 bolts; wherein the spring clamping mechanism 20 comprises a fixing seat 21, a clamping seat 22 and a spring 23, wherein The fixing seat 21 is vertically fixedly connected to the top of the horizontal base 11, wherein the clamping seat 22 extends in a direction perpendicular to the horizontal base 11 and is between the fixing seat 21 and the clamping substrate 12, and clamping ear plates 24 are symmetrically arranged on both sides of the clamping seat 22. In addition, the clamping substrate 12, the fixing seat 21 and the clamping seat 22 are correspondingly provided with test light channels 201 in a direction parallel to the horizontal base 11, so that color testing can be performed by a transmission method, wherein the spring 23 is elastically connected to the fixing seat 21 in a compressed manner. The clamping seat 22 and the fixing seat 21 are arranged between the clamping seat 22 and the fixing seat 21, so that the clamping seat 22 can be directional moved to approach or move away from the clamping substrate 12. In this way, in the initial state, based on the rebound force of the spring 23, the clamping seat 22 can be tightly pressed against the surface of the clamping substrate 12. When force is applied to the clamping ear plates 24 on both sides to overcome the elastic potential energy of the spring 23, the clamping seat 22 gradually moves away from the clamping substrate 12, thereby forming a gap between the clamping seat 22 and the clamping substrate 12, so that the diaphragm to be tested can be placed in the gap, and then the diaphragm to be tested can be removed. The pin overcomes the force of the elastic potential energy of the spring 23, and under the rebound action of the spring 23, the clamping seat 22 automatically resets, and can cooperate with the clamping substrate 12 to clamp the diaphragm. During the process of clamping the diaphragm, it is clamped vertically, so there will be no relative movement with the clamping part of the clamp, so the diaphragm will not or is not easy to be scratched. After the color measurement is completed, you only need to repeat the previous action to overcome the elastic potential energy of the spring 23 to take out the diaphragm. The operation is convenient. At the same time, the automatic clamping method based on the rebound force of the spring 23 has good clamping stability and reliability, which can ensure the quality of dental diaphragm color testing.
[0024] In one embodiment, a spring cavity 202 that cooperates with the spring 23 is provided on the side of the clamping seat 22 facing the fixed seat 21, and the spring cavity 202 extends in a direction parallel to the horizontal base 11. In addition, a spring groove 203 and a clamping seat groove 204 are provided on the side of the fixed seat 21 facing the clamping seat 22, wherein the spring groove 203 faces the spring cavity 202 and cooperates with the spring 23, and the clamping seat groove 204 cooperates with the outer side wall of the clamping seat 22. In this way, the accuracy of the extension and contraction direction of the spring 23 can be ensured based on the guiding and limiting effect of the spring cavity 202 and the spring groove 203. In addition, the accuracy of the moving direction of the clamping seat 22 can be ensured based on the guiding and limiting effect of the clamping seat 22 and the clamping seat groove 204. Then, the accuracy of the moving direction of the clamping seat 22 can be ensured from these two aspects at the same time, so that a stable positive clamping force can be maintained, and the diaphragm is not easily damaged.
[0025] In one embodiment, the spring cavity 202 is evenly distributed on the periphery of the clamping seat 22. For example, when the clamping seat 22 is a square seat, the spring cavity 202 and the spring 23 are respectively located at the four corners of the clamping seat 22. When the clamping seat 22 is a circular seat, the spring cavity 202 and the spring 23 are evenly distributed in the circumferential direction by three or four. In this way, a uniform clamping force can be provided by the evenly distributed springs 23, thereby ensuring the stability and reliability of the clamping force.
[0026] As a preferred embodiment, the sample fixing device for dental film color measurement also includes a toggle mechanism. The toggle mechanism includes a toggle plate 31, a connecting line 32 and a limiting pressure plate 33, wherein the toggle plate 31 includes a rotating shaft 311, a handle 312 vertically connected to the middle of the rotating shaft 311, and rotating plates 313 symmetrically and vertically arranged at both ends of the rotating shaft 311, wherein the rotating shaft 311 is rotatably arranged on the outer side wall of the fixing seat 21 and close to the top of the fixing seat 21, wherein the handle 312 protrudes upward from the fixing seat 21, and the two rotating plates 313 are abutted against the outer surface of the fixing seat 21 and are respectively connected to the two clamping ear plates 24 through the connecting line 32, wherein the limiting pressure plate 33 is between the handle 312 and the rotating plate 313, and is fixedly installed on the outer surface of the fixing seat 21, and is provided with a rotating groove 301 that is clearance-matched with the rotating shaft 311. Specifically, based on the limiting pressure plate 33 fixed on the outer surface of the fixing seat 21, when the handle 312 is turned, the rotating shaft 311 is directional rotated in the rotating groove 301, so that the rotating plate 313 rotates in the direction away from the fixing seat 21, and the rotating plate 313 pulls the connecting line 32. Based on the guide limiting of the spring cavity 202 and the spring groove 203, and the guide limiting of the clamping seat groove 204, the connecting line 32 drives the clamping seat 22 to be fixed. The clamping base 22 is moved away from the clamping base 12 to form a gap therebetween for placing a diaphragm. After the diaphragm is in place, the handle 312 is released. Under the rebound action of the spring 23, the clamping base 22 will be oriented to approach and gradually adhere to the surface of the clamping base 12, and then can cooperate with the clamping base 12 to firmly clamp and fix the diaphragm. At this time, color testing can be performed. Therefore, through the lever action, the diaphragm can be clamped and fixed and removed after color measurement with only a small force, which is easy to operate.
[0027] Further preferably, the connecting wire 32 is implemented as an elastic steel wire, and when the handle 312 is rotated to move the rotating plate 313 away from the fixed seat 21, the elastic steel wire can pull the clamping ear plate 24 to overcome the elastic potential energy of the spring 23, thereby moving the clamping seat 22 away from the clamping base plate 12. In this way, the elastic potential energy of the spring 23 can be slowly overcome by the elastic steel wire, so that the movement of the clamping seat 22 can be smoother and more reliable, and the diaphragm will not be damaged when the clamping seat 22 is opened after the test.
[0028] In one embodiment, when the rotating plate 313 is against the outer surface of the fixing base 21, the handle 312 extends in a direction away from the fixing base 21, and an angle between the handle 312 and a plane where the outer surface of the fixing base 21 is located is 25° to 45°, for example, 30°, so as to facilitate pressing the handle 312 and provide a large pressing space.
[0029] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
