[0037] Embodiment 1

[0038] like Figure 1-2 As shown, the utility model provides a glasses trial frame with adjustable pupil distance, comprising a nose pad 1, a lens frame 2 installed on both sides of the nose pad 1, an adjustment component, a widening component and a display component installed in the lens frame 2, a connecting component installed on the lens frame 2, a temple 3 installed in the connecting component and an extension component installed in the temple 3.

[0039] By setting an installation cavity 201 in the lens frame 2, setting a positioning cavity 202 in the installation cavity 201, the adjustment component is divided into a connecting rod 4 inserted in the installation cavity 201 and a positioning block 5 installed in the positioning cavity 202, a plurality of positioning grooves 401 are provided at equal intervals in a linear array on the connecting rod 4, so that the connecting rod 4 and the positioning block 5 collide with each other, and a positioning protrusion 501 adapted to the positioning groove 401 is provided on the surface of the positioning block 5 that contacts the connecting rod 4, and a positioning spring 502 is provided between the positioning block 5 and the installation cavity 201, so that the patient or medical staff can adjust the position of the lens frame 201 when adjusting the lens frame 201. When the pupil distance of the present frame is adjusted, the lens frame 2 can be held and then dragged to drive the connecting rod 4 to extend or retract. At this time, the positioning protrusion 501 will slide out of the positioning groove 401, and the positioning spring 502 will deform to accumulate elastic potential energy, so that the positioning protrusion 501 continues to resist the side wall of the connecting rod 4, and when the positioning protrusion 501 reaches the next positioning groove 401, the positioning protrusion 501 is pushed into the positioning groove 401 to be positioned again, thereby controlling the distance between the lens installed on the lens frame 2 and the nose pad 1, and quickly adjusting the pupil distance of the present frame.

[0040] Furthermore, the display component includes a sliding block 8 that is slidably connected in the installation cavity 201 and fixedly connected to the connecting rod 4, one end of a pointer 801 is arranged on the sliding block 8, and a connecting groove for the pointer 801 to pass through is opened in the installation cavity 201, so that the other end of the pointer 801 passes through the connecting groove and is arranged on the outer side of the lens frame 2, and scale lines 802 are arranged on the upper and lower sides of the connecting groove, so that when the connecting rod 4 is extended or retracted, the sliding block 8 will also be extended or retracted synchronously, thereby driving the pointer 801 to move on the scale lines 802, so that the patient or medical staff can simply and quickly know the pupil distance of the frame at this time by observing the position of the pointer 801 on the scale lines 802.

[0041] Embodiment 2

[0042] Based on the first embodiment, specifically, Figure 1 , Figure 3 and Figure 4 As shown, a partition is provided in the mounting cavity 201, and an adjustment component and a widening component are respectively provided on both sides of the partition. The widening component and the adjustment component adopt the same design. By providing a widening component with the same design as the adjustment component, the width of the frame can be adjusted in the same way as adjusting the pupil distance, so as to adapt to different head widths of different patients and enhance the versatility of the frame.

[0043] Specifically, an extension cavity 301 is provided in the temple 3, the extension leg 6 is inserted in the extension cavity 301, a plurality of fixing holes 302 are provided in a linear array at equal intervals on the top surface of the extension cavity 301, a fixing groove 601 is provided in the extension leg 6, a fixing block 603 is slidably connected in the fixing groove 601, and a fixing spring 602 is installed between the fixing groove 601 and the fixing block 603, so that the patient or medical staff can hold the temple 3 and the extension leg 6 respectively and pull the temple 3 and the extension leg 6 in the opposite direction, thereby driving the extension leg 6 to slide in the temple 3. When the fixing block 603 moves, the fixing block 603 will shrink back into the fixing groove 601 due to the sliding of the extension leg 6 and compress the fixing spring 602 to deform it. The fixing spring 602 will generate reverse elastic potential energy after deformation, and when the fixing block 603 reaches the next fixing hole 302, the elastic potential energy is converted into kinetic energy, driving the fixing block 603 to be re-engaged in the fixing hole 302, thereby realizing the length adjustment of the temple 3 of the present eyeglass frame, so as to adapt to the distance between the ear and the face of different patients, further improving the versatility of the present eyeglass frame.

[0044] In addition, the connecting component includes a rotating seat 7 fixedly connected to the connecting rod 4 in the widening component, a bolt 701 is inserted in the rotating seat 7, a threaded through hole 702 is opened in the rotating seat 7, the bolt 701 is threadedly connected to the threaded through hole 702, a hole is opened in the temple 3, and the temple 3 is rotatably connected to the outer wall of the bolt 701 through the hole, so that the temple 3 can be removed from the lens frame 2 by unscrewing the bolt 701 from the rotating seat 7, and the lens frame 2 or the temple 3 can be cleaned or maintained separately, thereby improving the convenience of later maintenance.

[0045] Working principle:

[0046] When in use, first, based on the pupil distance obtained from one's own eyesight test and the position of the pointer 801 on the scale line 802, one can hold the nose pad 1 and pull the lens frame 2 to drive the connecting rod 4 to extend or retract. At this time, the positioning protrusion 501 will slide out of the positioning groove 401, and the positioning spring 502 will deform to accumulate elastic potential energy, so that the positioning protrusion 501 will continue to resist the side wall of the connecting rod 4, and when the positioning protrusion 501 reaches the next positioning groove 401, the positioning protrusion 501 will be pushed into the positioning groove 401 to be positioned again, thereby controlling the distance between the lens mounted on the lens frame 2 and the nose pad 1, and quickly adjusting the pupil distance of the frame.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
