DETAILED DESCRIPTION
[0021] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.
[0022] like Figure 1-5 As shown, this embodiment provides a gem refractometer reading auxiliary bracket, including a base 1, a sliding assembly 2, an angle adjustment slide rail 3, a six-section telescopic rod 4 and a circular field of view bracket 5.
[0023] The base 1 is the basis for installing the angle adjustment rail 3, the sliding assembly 2, the six-section telescopic rod 4 and the circular field of view bracket 5. In this embodiment, the base 1 includes a triangular bracket 11 and an L-shaped bracket 12. The triangular bracket 11 has a large bottom area (which can be a virtual area or a projected area) to prevent the device from tipping over. The L-shaped bracket 12 is fixed to the top of the triangular bracket 11, one leg of the L-shaped bracket 12 is horizontally arranged, and the other leg is vertically arranged. The L-shaped bracket 12 is used to install the angle adjustment rail 3. Exemplarily, the L-shaped bracket 12 is welded and fixed to the triangular bracket 11.
[0024] The angle adjustment rail 3 is arranged on the base 1. In the present embodiment, the angle adjustment rail 3 is in the shape of a semicircular arc, and the two ends of the angle adjustment rail 3 are respectively fixed to the two legs of the L-shaped bracket 12. Exemplarily, the angle adjustment rail 3 is welded and fixed to the L-shaped bracket 12 or detachably connected by bolts. When in use, the gem refractometer reading auxiliary bracket is placed on one side of the gem refractometer 100, so the side of the angle adjustment rail 3 facing the gem refractometer 100 is defined as the inner side, the side of the angle adjustment rail 3 away from the gem refractometer 100 is defined as the outer side, and the side of the angle adjustment rail 3 away from the arc center is defined as the upper side; under this definition, a slide groove 31 is provided on the inner side of the angle adjustment rail 3, and a sliding seam 32 connected to the slide groove 31 is provided on the outer side of the angle adjustment rail 3. Since the angle adjustment rail 3 is in the shape of an arc, the slide groove 31 and the sliding seam 32 arranged along it are also in the shape of an arc, and a scale line 33 showing the angle is provided on the upper side of the angle adjustment rail 3.
[0025] The sliding assembly 2 is slidably connected to the angle adjustment rail 3. In this embodiment, the sliding assembly 2 includes a slider 21 and a set screw 22. The slider 21 is arranged on the inner side of the angle adjustment rail 3, and one end of the slider 21 is adapted in the slide groove 31; for example, the part of the slider 21 in the slide groove 31 is in the shape of an arc block. The set screw 22 is arranged on the outer side of the angle adjustment rail 3, and the set screw 22 passes through the sliding slit 32 and is threadedly connected with the slider 21. When adjusting the angle, loosen the set screw 22, and the sliding slider 21 can change its position in the slide groove 31, thereby adjusting the angle; after the angle adjustment is completed, manually tighten the set screw 22, and the set screw 22 and the slider 21 clamp the angle adjustment rail 3, and the slider 21 cannot move along the slide groove 31, and the locking is completed. A pointer 23 is provided on the top of the slider 21, and the needle tip of the pointer 23 is located at the scale line 33. In this way, when the angle is adjusted and the position of the slider 21 is changed, the pointer 23 moves accordingly, and the adjusted angle value can be more clearly known.
[0026] The six-section telescopic rod 4 refers to a telescopic rod with a total of six sections, one end of which is connected to the sliding assembly 2, and the other end is connected to the circular field of view bracket 5. The length of the six-section telescopic rod 4 in the retracted state is 6 cm, and it can increase by 6 cm each time it is extended. When the six-section telescopic rod 4 is parallel to the axis of the eyepiece 101 of the gem refractometer 100 (achieved by adjusting the position of the gem refractometer reading auxiliary bracket and adjusting the sliding assembly 2; when parallel, the position of the gem refractometer reading auxiliary bracket will no longer change, and only the sliding assembly 2 and the six-section telescopic rod 4 are adjusted during the subsequent operation), the distance from the circular field of view bracket 5 to the eyepiece 101 is 3.5 cm, so as to meet the use in the myopia method mode.
[0027] The circular viewing bracket 5 is connected to the upper end of the six-section telescopic rod 4 through a crossbar 51. In this embodiment, the circular viewing bracket 5 is in a circular ring shape, with a mounting groove 52 on the upper part so as to temporarily place or install an eyepiece lens 6 when in use, and a through hole 53 connecting the mounting groove 52 and the lower side of the circular viewing bracket 5 is provided on the lower part so that light can pass through the circular viewing bracket 5. Among them, the through hole 53 is a circular hole, that is, a circular viewing area; the mounting groove 52 and the through hole 53 can also be combined to be regarded as a circular viewing area, so the mounting groove 52 should be a circular groove.
[0028] The utility model provides a gem refractometer reading auxiliary bracket. In a hyperopia mode, the six-section telescopic rod 4 is stretched to a required size state (24-36 cm, and since each section is 6 cm, the length of 24-36 cm can be obtained by pulling out 3-5 sections), the sliding component 2 is adjusted to slide along the angle adjustment slide rail 3 to adjust the angle of the six-section telescopic rod 4, the dripping area is observed through the circular field of view at the circular field of view bracket 5, the sliding component 2 is fixed when the droplet is half light and half dark, and the scale number of the light-dark dividing line on the scale of the refractometer is read from the circular field of view bracket 5, and the scale number is retained to 2 decimal places; in a myopia mode, the six-section telescopic rod 4 is retracted to the shortest size state (6 cm), the angle is adjusted to 45 degrees, and after the light-dark dividing line is observed from the circular field of view bracket 5, the scale number of the light-dark dividing line on the scale of the refractometer is read, and the scale number is retained to 3 decimal places, and then the gem is gently rotated 360 degrees, the readings are read in sequence, and the change of the dividing line is recorded. By using the gem refractometer reading auxiliary bracket, the problems of inaccurate operating posture, reading direction (angle) and reading distance can be solved, which provides convenience for teachers to quantify teaching content and students to master professional skills more directly. It is suitable for use in the practical operation of identification instruments in junior colleges, undergraduate and vocational education of gem identification majors, and has good universality.
