Description

Technical Field

[0001] The utility model relates to the technical field of trial glasses frames, in particular to a trial glasses frame with adjustable ring diameter. Background Art

[0002] After an eye examination, patients with refractive errors need to wear trial frames. The optometrist will then attach lenses of different degrees of myopia, hyperopia and astigmatism to the rings of the trial frames. When the degree of the lenses on the rings matches the patient's refractive power, the patient needs to wear the trial frames for a period of time to verify whether the degree is appropriate. Different lens sizes will lead to different eye sensations. The larger the lens, the more uncomfortable it is, and the smaller the lens, the more comfortable it is.

[0003] After searching, the application with patent number 202221322001.4 discloses a pair of ophthalmic trial glasses with a protective structure, including two frames, two frames with lenses fixedly installed inside, the top and bottom of the frames are provided with protective edges, the top of the inner wall of the protective edge is provided with grooves on both sides, the center of the top of the groove is fixedly connected to a spring, the bottom of the spring is fixedly connected to a limit block, and the top and bottom of the frame are fixedly connected to connecting blocks on both sides;

[0004] Although the ophthalmic trial glasses with a protective structure can protect the frame through the protective edge to prevent the frame from being worn by the ground, and the spring and rubber head can cushion the glasses when they fall on the ground to prevent the lenses from being damaged by the inertia of the fall, the frame of the ophthalmic trial glasses with a protective structure cannot fix lenses of different specifications, which makes it inconvenient for patients to experience the wearing feeling of lenses of different sizes.

[0005] Therefore, we propose a trial glasses frame with adjustable ring diameter. Utility Model Content

A fixing component 3 is set in the rectangular groove 21, and the fixing component 3 includes a threaded rod 31, a slider 32, a knob 33, The connecting rod 34 and the clamping block 35 are arranged at the bottom of the rectangular groove 21. The two ends of the threaded rod 31 are rotatably mounted on the inner wall of the rectangular groove 21 through bearings. The outer surface of the threaded rod 31 is threaded with two sliders 32 with opposite thread directions and slidingly mounted at the bottom of the rectangular groove 21. The middle part of the top surface of the slider 32 is fixedly mounted with a connecting rod 34, and the top of the connecting rod 34 is fixedly mounted with a clamping block 35. One end of the threaded rod 31 passes through the side wall of the frame 2 and is fixedly mounted with a The knob 33 has anti-slip grooves evenly distributed on the surface of the knob 33, and the central axis of the clamping block 35 is flush with the central axis of the frame 2. The side wall of the clamping block 35 is penetrated by an arc groove 36, and the top surface of the clamping block 35 is provided with three rectangular card slots 37 connected to the arc groove 36. The positions of the three rectangular card slots 37 are opposite to the glasses fitting slot 22, and the thickness of the three rectangular card slots 37 is the same as that of the glasses fitting slot 22. Damping pads are bonded to the inner walls of the rectangular card slots 37 and the glasses fitting slot 22. By passing the lens through the glasses fitting slot 22 and then rotating the threaded rod 31 by the knob 33, the clamping block 35 can be driven to move to the two sides of the lens, and then the two sides of the lens will be clamped in the inside of the rectangular card slot 37, achieving the purpose of clamping and fixing the lens. By rotating the threaded rod 31 by the knob 33, the distance between the two clamping blocks 35 can be adjusted, thereby achieving the purpose of facilitating the clamping and fixing of lenses of different specifications, so that patients can change lenses of different specifications for wearing experience;

[0028] Example 2:

[0029] like Figure 1 and 5As shown: the temple 4 includes a connecting leg 41, a plug-in plate 42, an extension leg 43 and a bolt 46. The connecting leg 41 is hinged to the middle of the side wall of the frame 2. The plug-in plate 42 is fixedly installed in the middle of the connecting leg 41 away from the frame 2. The middle of the side of the extension leg 43 close to the connecting leg 41 is provided with a plug-in slot 44 of the same specification as the plug-in plate 42. The plug-in plate 42 is movably sleeved inside the plug-in slot 44.

The axial scale groove 51 is convenient for observing the degree of rotation of the astigmatism lens, so as to facilitate reading the axial direction of the astigmatism.

[0032] The working principle and usage process of the present invention are as follows: when using the trial glasses frame with adjustable ring diameter, the patient wears the trial glasses frame, and the optometrist first passes the lens through the fitting groove 22. Then, the optometrist drives the threaded rod 31 to rotate by the knob 33, and then drives the slider 32 to translate along the inner wall of the rectangular groove 21, so that the connecting rod 34 and the clamping block 35 at the top of the rectangular groove 21 can move toward the two sides of the lens, and then the two sides of the lens will be clamped in the inner wall of the rectangular clamping groove 37, which can clamp and fix the lens. By driving the threaded rod 31 to rotate by the knob 33, the distance between the two clamping blocks 35 can be adjusted, so as to clamp and fix lenses of different specifications. The optometrist rotates the astigmatic lens and reads the deflection degree of the astigmatic lens through the axial scale groove 51, and then reads the axial direction of the patient's astigmatism. The astigmatic lens can be rotated to a certain angle and then limited by the damping pad bonded to the inner wall of the rectangular clamping groove 37 and the fitting groove 22.
