[0002] The trial frame mechanism, also called the optometry trial frame, is used when conducting vision tests at eyewear stores. A number of test lenses with different degrees are prepared in advance, and the subject is asked to wear the trial frame mechanism and replace different test lenses in the lens slots of the trial frame mechanism to obtain lenses suitable for the subject's vision strength.

[0003] The lens slots of the existing trial-fitting frame mechanism are usually fixedly mounted on the frame of the trial-fitting frame mechanism by metal screws. Due to the need for optometry, the number of lens slots is generally three to five.

[0004] However, the current trial fitting frames have certain design flaws. The inserted test lenses are blocked by the lens slots on both sides, and the test lenses cannot be rotated 180 degrees (there is a 0-180° scale on the frame), resulting in the inability to test astigmatism and polarization at some angles, and thus failing to meet usage requirements. Summary of the invention

[0032] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0033] In the prior art, there is an inserted test lens in the trial fitting frame. Due to the obstruction of the lens slots on both sides, the test lens cannot be rotated 180 degrees (there is a 0-180° scale on the frame), resulting in the inability to test astigmatism and polarization at some angles, and thus failing to meet the use requirements.

[0034] In order to overcome the above defects, the present invention provides a trial fitting frame mechanism and a trial fitting frame including the trial fitting frame mechanism.

[0035] The following is combined with specific Figure 1-6 The structure of a preferred embodiment of the trial fitting frame mechanism of the present invention is described in detail.

[0036] like Figure 1 and Figure 2 , which is a schematic structural diagram of a try-on frame 1 mechanism of the present invention, wherein the try-on frame 1 mechanism comprises a frame 1, an insert slot assembly 3 and an annular support seat assembly 2.

[0037] The structure of the frame 1 in this embodiment is consistent with the structure of the frame 1 in the prior art. A single frame 1 is a semicircular ring structure, and has a scale on the frame 1, and the scale ranges from 0 to 180 degrees.

[0038] The annular support seat assembly 2 is installed on the inner wall of the frame 1, and the insertion slot assembly 3 is installed on the inner wall of the annular support seat assembly 2. The annular support seat assembly 2 can rotate relative to the frame 1. When the annular support seat assembly 2 rotates, the insertion slot assembly 3 is driven to rotate. The arc of rotation of the annular support seat assembly 2 relative to the frame 1 is used to compensate for the arc of the test lens blocked by the insertion slot assembly 3, thereby allowing the test lens to rotate 180 degrees.

[0039] In order to realize the relative rotation between the lens frame 1 and the annular support assembly, an arc-shaped groove 212 is provided on the outer ring wall of the annular support seat assembly 2 of the present embodiment, and the two free ends of the semicircular ring-shaped lens frame 1 are installed in the arc-shaped groove 212, and when driven by external force, the two free ends of the semicircular ring-shaped lens frame 1 can slide in the arc-shaped groove 212, that is, the semicircular ring-shaped lens frame 1 and the annular support assembly rotate relative to each other.

[0040] Specifically, Figure 3-5As shown, the annular support seat assembly 2 includes a first seat body 21 and a second seat body 22. The first seat body 21 is an annular structure, and the second seat body 22 is a semi-annular structure. The second seat body 22 is fixed on the first seat body 21 and forms an arc-shaped slide groove 212 between the second seat body 22 and the first seat body 21.

[0041] In this embodiment, the second base body 22 is fixedly arranged on the first base body 21 by screws or bolts. Figure 4 The first seat body 21 and Figure 5 The second base body 22 has a connecting hole 222, and screws or bolts are inserted into the connecting hole 222 to achieve the connection and fixation between the first base body 21 and the second base body 22.

[0042] Furthermore, a first outer edge is provided on the first seat body 21, and the first outer edge is arc-shaped, extending outward from the first seat body 21, and is integrally formed with the first seat body 21. A second outer edge is provided on the second seat body 22, and the second outer edge is also arc-shaped, extending outward from the second seat body 22, and is integrally formed with the second seat body 22. The second outer edge is provided above the first outer edge.

[0043] Furthermore, a first arc-shaped flange 211 is provided on the first outer edge, and a second arc-shaped flange 221 is provided on the second outer edge. When the second seat body 22 is installed on the first seat body 21, the first arc-shaped flange 211 and the second arc-shaped flange 221 are opposite to each other.

[0044] Due to the presence of the first arc-shaped flange 211 on the first seat body 21 and the second arc-shaped flange 221 on the second seat body 22, an arc-shaped slide groove 212 is formed on both sides of the first arc-shaped flange 211 and the second arc-shaped flange 221, and between the first seat body 21 and the second seat body 22. The two free ends of the semicircular ring-shaped frame 1 can slide in the arc-shaped slide groove 212. In this way, when the insert slot assembly 3 is installed on the first seat body 21 and the second seat body 22, the scale on the frame 1 will not be blocked. Even if it is blocked, an external driving force is used to drive the semicircular ring-shaped frame 1, so that the semicircular ring-shaped frame 1 and the first seat body 21 and the second seat body 22 rotate relative to each other, thereby rotating the test lens 180 degrees.

[0045] In order to fix the insert slot assembly 3 on the first base body 21 and the second base body 22, as shown in FIG. Figure 4 and Figure 5 As shown, hooks 213 are provided on opposite sides of the inner side walls of the first seat body 21 and the second seat body 22 , and the hooks 213 are used to fix the inserting slot assembly 3 .

[0046] In addition, in order to strengthen the fixing strength of the insert slot assembly 3 on the first seat body 21 and the second seat body 22, as shown in FIG. Figure 4As shown, serrations 11 are provided on opposite sides of the inner wall of the frame 1, and the curvature of the serrations 11 on both sides is greater than or equal to the curvature of the arc-shaped slide groove 212 adjacent thereto, so that when the free end of the frame 1 slides to the extreme position of the arc-shaped slide groove 212, the serrations 11 can still play a role in strengthening and fixing the insert slot assembly 3.

[0047] And in order to further strengthen the connection strength between the frame 1 and the first base 21, as Figure 4 As shown, a locking block 214 is provided on the first seat body 21 adjacent to the hook head 213. The locking block 214 can be deformed to adapt to the rotation state and the braking state. When an external force is applied to rotate the frame 1 to the appropriate position, the locking block 214 is inserted between adjacent serrations 11.

[0048] In this embodiment, the saw teeth 11 on the frame 1 and the locking block 214 on the first base 21 facilitate the reading of the angle of the test lens and prevent the test lens from rotating due to movement during wearing.

[0049] like Figure 1 As shown, the insert slot assembly 3 of this embodiment is a common structure in the prior art, which includes a plurality of insert slots 31 , for example, three insert slots 31 .

[0050] like Figure 6 As shown, it is a diagram of the changing state of the frame mechanism of the trial fitting frame of this embodiment. When a test lens is installed, the arc of rotation of the annular support seat assembly 2 of the present invention relative to the frame 1 compensates for the arc of the test lens blocked by the insertion slot assembly 3, thereby allowing the test lens to rotate 180 degrees.

[0051] The present invention also provides a try-on frame, comprising the above-mentioned try-on frame frame mechanism, the try-on frame frame mechanism is arranged in pairs, and also comprises temples and a connecting rod for connecting the try-on frame mechanism.
