[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] According to an embodiment of the utility model, a fixing device is provided. Figures 1 to 3 , including: a stage 1 and a support structure 2 for supporting the stage 1, the stage 1 including a bearing surface 11 and a bearing groove 12, the bearing surface 11 is located at one end of the stage 1 away from the support structure 2, the bearing groove 12 is a spherical structure recessed in the portion where the bearing surface 11 is set, and an anti-skid mechanism 3 is set on the bearing groove 12, the anti-skid mechanism 3 includes a first anti-skid mechanism 31 and a second anti-skid mechanism 32 for abutting against the sample located in the bearing groove 12, the first anti-skid mechanism 31 is set at the bottom of the inner wall of the bearing groove 12, and the second anti-skid mechanism 32 is set on the inner side wall of the bearing groove 12. Put the spherical sample into the bearing groove 12, the outer surface of the spherical sample abuts against the first anti-skid mechanism 31 and the second anti-skid mechanism 32, so that the spherical sample is fixed in the bearing groove 12, and then the instrument is used to measure or test the spherical sample. The spherical sample is supported by the supporting groove 12 and fixed by the anti-skid mechanism, so that the spherical sample can be stably fixed on the stage 1. The spherical sample is not prone to sliding or rolling during measurement and testing, which enhances stability and reduces measurement and test errors.

[0026] Specifically, the second anti-skid mechanism 32 of this embodiment includes a plurality of anti-skid parts, which are arranged at intervals on the inner wall of the bearing groove 12. The plurality of anti-skid parts can make the spherical sample more fixed in the bearing groove 12, and is not easy to shake, thereby affecting the measurement or test data.

[0027] Specifically, see Figure 2The anti-skid portion of this embodiment includes a first anti-skid portion 321, a second anti-skid portion 322, a third anti-skid portion 323 and a fourth anti-skid portion 324 distributed along the circumferential direction. The first anti-skid portion 321 and the second anti-skid portion 322 are symmetrically arranged on the inner side wall of the bearing groove 12, and the third anti-skid portion 323 and the fourth anti-skid portion 324 are symmetrically arranged on the inner side wall of the bearing groove 12. When the spherical sample is placed in the bearing groove 12, the outer surface of the spherical sample abuts against the first anti-skid portion 321, and the outer surface of the spherical sample abuts against the second anti-skid portion 322 on the same horizontal line as the first anti-skid portion 321; the outer surface of the spherical sample abuts against the third anti-skid portion 323 on the horizontal line perpendicular to the first anti-skid portion 321; and the outer surface of the spherical sample abuts against the fourth anti-skid portion 324 on the same horizontal line as the third anti-skid portion 323. In this arrangement, the spherical sample abuts against each anti-slip portion, so that the anti-slip portion can clamp the spherical sample, so that the spherical sample is stably fixed in the bearing groove 12.

[0028] Specifically, see Figure 3 In this embodiment, the first anti-skid mechanism 31 is sealed and connected to one end of the bottom of the inner wall of the first anti-skid part 321; the first anti-skid mechanism 31 is sealed and connected to one end of the bottom of the inner wall of the second anti-skid part 322; the first anti-skid mechanism 31 is sealed and connected to one end of the bottom of the inner wall of the third anti-skid part 323; the first anti-skid mechanism 31 is sealed and connected to one end of the bottom of the inner wall of the fourth anti-skid part 324 near the bottom of the inner wall of the bearing groove 12. When the spherical sample is placed in the bearing groove 12, the first anti-skid mechanism 31, the first anti-skid part 321, the second anti-skid part 322, the third anti-skid part 323 and the fourth anti-skid part 324 are all in contact with the outer surface of the spherical sample, and because the first anti-skid mechanism 31 is sealed and connected to each anti-skid part, even if the spherical sample is squeezed in the bearing groove 12, it is not easy to slip sideways in the bearing groove 12. In this way, the spherical sample is clamped by the first anti-slip mechanism 31 and the anti-slip parts through the contact between the first anti-slip mechanism 31 and the anti-slip parts, thereby enhancing the stability of the spherical sample in the bearing groove 12.

[0029] Specifically, see Figure 1 In this embodiment, there are multiple bearing grooves 12, and the multiple bearing grooves 12 are arranged at intervals on the bearing surface 11. The arrangement of multiple bearing grooves 12 can measure or test multiple spherical samples, thereby enhancing the functionality of the fixing device of this embodiment.

[0030] Specifically, the second anti-slip mechanism 32 of this embodiment is multiple. In actual operation, multiple second anti-slip mechanisms 32 can be provided according to test or measurement requirements to enhance the stability of the spherical sample in the bearing groove 12.

[0031] Specifically, the first anti-skid mechanism 31 of this embodiment is a silicone plate, and / or the second anti-skid mechanism 32 is a silicone strip. A 1mm thick silicone plate can be placed at the bottom of the bearing groove, and then 4 1mm thick silicone strips can be placed on the inner wall of the bearing groove. The bearing groove 12 is set to have a diameter of 12mm and a height of 5mm. For spherical samples with a diameter of 11-14mm, both the silicone strip and the silicone plate can play a fixing role, and the spherical sample will not slide, and at the same time, it also avoids damage caused by the shaking and rolling of the spherical sample.

[0032] Specifically, the stage 1 of this embodiment is a ceramic plate, which has strong wear resistance and long service life, thus saving the replacement cost of the stage 1 .

[0033] Specifically, the stage 1 and the support structure 2 of this embodiment are both cylindrical structures. The cylindrical structure has strong stability, and the spherical sample is not easy to shake during measurement or testing, which improves the accuracy of measurement and test data.

[0034] Specifically, the bearing groove 12 of this embodiment is provided with anti-skid grooves. When the spherical sample is placed in the bearing groove 12, the anti-skid grooves can rub against the outer surface of the spherical sample to prevent the spherical sample from shaking, thus playing a good fixing role.

[0035] Many other changes and modifications can be made without departing from the concept and scope of the utility model. It should be understood that the utility model is not limited to a specific embodiment, and the scope of the utility model is defined by the appended claims.
