[0035] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1-8 As shown,

[0036] A telescopic temple structure for glasses comprises a temple 1 and a frame 2, wherein the temple 1 comprises a hinge section 11 and a telescopic section 12, wherein the hinge section 11 is hingedly matched with the frame 2, a metal square tube 13 is arranged on the end surface of the hinge section 11 away from the frame 2, wherein the metal square tube 13 is provided with a slot 131, and the telescopic section 12 is provided with a metal temple 14 and a square metal ring 15, wherein the metal temple 14 comprises a pin portion 141 arranged in the telescopic section 12, and a plug portion 142 adapted to the contour of the slot 131 for sliding fit.

[0037] On the end surface of one side of the plug-in portion 142, a plurality of limiting grooves 1421 with different lengths are arranged in parallel along the sliding direction. The plurality of limiting grooves include a starting end 1422 with uniformly aligned positions and an end end with different lengths. The starting end 1422 is close to one side of the telescopic section 12.

[0038] The hinge section and the metal square tube 13 are coaxially provided with a mounting countersunk hole 15 penetrating the starting end 1422 of the limiting groove 1421. The center position of the mounting countersunk hole 15 coincides with the midpoint line of the total width direction of the plurality of limiting grooves 1421. The mounting countersunk hole 15 includes a large diameter end close to one side of the limiting groove 1421 and a small diameter end on the other side.

[0039] The plurality of limit grooves 1421 are arranged around the center of the mounting countersunk hole 15, and an arc groove 1423 is arranged to penetrate each limit groove 1421; the temple 1 also includes a shift member 3, which includes a rotating shaft 31, a turntable 32, and a shift column 33. The turntable 32 is arranged at the large diameter end for circumferential cooperation, and the rotating shaft 31 passes through the small diameter end. The shift column 33 is arranged around the center of the turntable 32, and the radius from the center of the circle is adapted to the radius of the arc groove 1423. The diameter of the shift column 33 is equal to or less than the width of a single limit groove 1421. The shift column extends into the arc groove 1423 and rotates with the turntable 32 to each limit groove 1421.

[0040] Through the sliding cooperation between the plug-in portion 142 and the metal square tube 13, the telescopic section 12 of the temple 1 can be slidably adjusted relative to the hinge section 11 in the length direction. At the same time, by providing a plurality of limit grooves 1421 of different lengths on the plug-in portion 142, and providing a mounting countersunk hole 15 and a gear member 3 on the hinge section 11, as shown in the appendix of the manual Figure 4 , 6 As shown in Figures 7 and 8, the shift member 3 is rotated circumferentially in the mounting countersunk hole 15 to adjust the angle, driving the shift column 33 along the arc groove 1423 to enter each limit groove 1421. When the telescopic section 12 is pulled out, the consumer can adjust the shift column to enter the limit groove 1421 corresponding to the telescopic length according to his or her own telescopic length requirements, and then pull out the telescopic section 12. At this time, the shift column collides with the end point of the limit groove 1421 selected by the wearer, and the length required by the wearer can be achieved.

[0041] This design eliminates the need for the wearer to align the lengths of the temples 1 on both sides or adjust the lengths every time the temples 1 are extended or retracted, thereby helping the wearer to conveniently extend or retract the length of the temples 1 and providing a variety of length gears for adjustment.

[0042] A cap 34 is provided on one side of the rotating shaft 31 passing through the small diameter end, and a direction mark is provided on the cap 34 .

[0043] This makes it convenient for the wearer to twist the cap 34 and identify which limit groove 1421 the gear column has entered.

[0044] The hinge section is provided with an embedding groove corresponding to the cap member 34 .

[0045] The embedding groove is provided to prevent the cap member 34 from protruding out of the temple 1 .

[0046] The limiting groove 1421 and the mounting countersunk hole 15 are both located on the vertical upper side end surface when the glasses are worn.

[0047] A detachable adjustment block is embedded at one side of the end point of each limiting groove 1421 .

[0048] By embedding an adjustment block at the end of each limiting groove 1421, the wearer can further make personalized length adjustments to the standard length limiting groove 1421 according to his or her own needs.

The ear hook 4 fits the end surface of the telescopic section 12, and a second magnet 41 is embedded in the position corresponding to the first magnet 122.

[0050] By adopting the above technical solution, the ear hanging member 4 is hingedly connected to the hinge seat 121 at the end of the telescopic section 12 to achieve the flipping toward the ear side, as shown in the attached manual. Figure 8 As shown, by turning it over, the straight leg structure temple 1 can be deformed to form an ear hook structure. The first and second magnets 41 are provided so that when the wearer needs a straight leg structure, the ear hook 4 is magnetically attracted to maintain the straight leg contour.

[0051] Through the sliding cooperation between the plug-in part 142 and the metal square tube 13, the telescopic section 12 of the temple 1 can be slidably adjusted in the length direction relative to the hinge section 11. At the same time, by setting a plurality of limit grooves 1421 of different lengths on the plug-in part 142, setting an installation countersunk hole 15 and a shift member 3 on the hinge section 11, the shift member 3 can make circumferential rotation adjustment angle in the installation countersunk hole 15, and drive the shift column 33 to enter each limit groove 1421 along the arc groove 1423. When pulling out the telescopic section 12, the consumer can adjust the shift column to enter the limit groove 1421 of the corresponding telescopic length according to his own telescopic length requirements, and then pull out the telescopic section 12. At this time, the shift column conflicts with the end point of the limit groove 1421 selected by the wearer, and the length required by the wearer can be achieved.

[0052] The ear hanging piece 4 is designed so that the straight-leg structure temple 1 can be deformed to bend toward the back of the ear, making it more stable to wear.
