Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The following description, in conjunction with the accompanying drawings, details a pair of retractable temple glasses provided in this application through specific embodiments and application scenarios.

[0029] Example 1:

[0030] like Figure 1 and Figure 4 As shown, this application embodiment provides a pair of glasses with retractable temples, including a frame 1, nose pads 2, hinges 3, a pair of temples 4, and a lanyard 5. Each pair of temples 4 includes a temple thread 41 and a temple sleeve 42. Each end of the lanyard 5 is provided with a fixing block 51. Each pair of temple threads 41 is provided with a mounting groove 61. Each mounting groove 61 is provided with an unlocking member 62 and a fixing member 63. The fixing block 51 is inserted into the mounting groove 61 and passes through the unlocking member 62 and the fixing member 63 in sequence. The fixing member 63 is used to fix the fixing block 51 in the corresponding mounting groove 61. The unlocking member 62 can release the fixing member 63.

[0031] Furthermore, the fastener 63 includes a pair of fixing springs 631, and a pair of symmetrical fixing springs 631 are fixedly installed in the mounting groove 61. The fixing block 51 is provided with a groove 52, and the pair of fixing springs 631 press against the groove 52 on the corresponding fixing block 51.

[0032] Furthermore, the unlocking component 62 includes a pressing block 621 and a pushing block 622. The pressing block 621 is slidably installed in the mounting groove 61. One end of the pressing block 621 abuts against a pair of corresponding fixing springs 631. The top of the lead screw 41 is provided with a connecting groove 624 that communicates with the mounting groove 61. The pushing block 622, which extends out of the lead screw 41, is fixedly connected to the outer peripheral wall of the pressing block 621. The pushing block 622 is slidably installed in the connecting groove 624. The pressing block 621 is provided with a transverse groove 623 that penetrates its left and right end faces.

[0033] Furthermore, the transverse groove 623 is a circular groove, and the fixing block 51 is a cylindrical block, with the diameter of the transverse groove 623 being larger than the diameter of the fixing block 51.

[0034] In this embodiment of the application, due to the above-described structure, when installing the hanging rope 5, the fixing blocks 51 at both ends of the hanging rope 5 are respectively inserted into a pair of mounting slots 61. During the insertion process, the fixing blocks 51 will push the corresponding pair of fixing spring pieces 631 to open outward until the fixing blocks 51 are fully inserted into the mounting slots 61. At this time, the corresponding pair of fixing spring pieces 631 elastically recover and press against the groove 52 of the fixing block 51. When the fixing block 51 is pulled outward, the pair of fixing spring pieces 631 will abut against the groove 52 of the corresponding fixing block 51, and the fixing block 51 will not easily slip out.

[0035] When removing the hanging rope 5, the push block 622 can be pushed towards the frame 1. The push block 622 will drive the pressing block 621 to slide synchronously. During the sliding process, the pressing block 621 will lift the corresponding pair of fixing springs 631, causing the pair of fixing springs 631 to disengage from the grooves 52 on the corresponding fixing block 51. Then, pull it outward to disengage the fixing block 51. After the fixing block 51 is disengaged, the push block 622 and the pressing block 621 will reset under the action of the fixing springs 631. When both fixing blocks 51 at both ends are disengaged, the hanging rope 5 is completely removed.

[0036] Users can choose a matching size lanyard 5 to install on the foot thread 41 as needed.

[0037] Example 2:

[0038] like Figures 1 to 3As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the front end of the foot cover 42 is provided with a sliding groove 421 along its length direction, and a plurality of insertion holes 422 are provided in the sliding groove 421. A plurality of insertion blocks 411 are provided at the opposite ends of a pair of foot threads 41. The plurality of insertion blocks 411 are distributed at equal intervals along the length direction of the corresponding foot threads 41, and the plurality of insertion blocks 411 can be inserted into the plurality of insertion holes 422 respectively.

[0039] Furthermore, annular grooves 412 are provided between several plug-in blocks 411 located at the end of the lead screw 41.

[0040] Furthermore, the movable connection between the foot screw 41 and the foot sleeve 42 requires at least three plug blocks 411 to be inserted into the plug hole 422.

[0041] Furthermore, the length of the temple 4 can be adjusted within the range of 130mm-145mm.

[0042] Furthermore, the foot threads 41 are made of PPSU material, and the foot covers 42 are made of solid food-grade silicone.

[0043] Furthermore, the foot cover 42 is provided with heat dissipation holes 423.

[0044] In this embodiment of the application, due to the above-described structure, a pair of temples 4 are hinged to both ends of the frame 1 via corresponding hinges 3. The nose pads 2 are fixed on the frame 1. The lateral distance of the sliding groove 421 is less than the vertical distance. When the user needs to adjust the length of the temples 4, since the temple sleeves 42 are made of solid food-grade silicone, the temple threads 41 can rotate inside the temple sleeves 42. After rotating 90 degrees, since the lateral distance of the sliding groove 421 is less than the vertical distance, the insertion block 411 can be prevented from contacting the temple sleeves 42. Then, push or pull the temple sleeves 42. When the length is adjusted to a suitable length, rotate 90 degrees in the opposite direction so that the insertion block 411 is re-inserted into the insertion hole 422, and the adjustment can be completed.

[0045] At least three connector blocks 411 are inserted into the connector hole 422 between the lead screw 41 and the foot sleeve 42, which can effectively prevent the lead screw 41 and the foot sleeve 42 from accidentally separating.

[0046] The temple 41 has eight equally spaced insertion blocks 411, and the slide groove 421 has six equally spaced insertion holes 422. Since it is necessary to ensure that at least three insertion blocks 411 are inserted into the insertion holes 422, the length of the temple 4 can be adjusted in four ranges: 136mm, 139mm, 142mm and 145mm.

[0047] When the above four settings cannot meet the user's needs, the lead screw 41 can be broken along the annular groove 412 to enable it to reach a larger adjustment range.

[0048] When the temple wire 41 breaks off along the annular groove 412 away from the end of the frame 1, there are seven equally spaced insertion blocks 411 on the temple wire 41, and six equally spaced insertion holes 422 in the sliding groove 421. Since it is necessary to ensure that at least three insertion blocks 411 are inserted into the insertion holes 422, the length of the temple 4 can be adjusted in four ranges: 133mm, 136mm, 139mm and 142mm.

[0049] When the temple wire 41 breaks along the annular groove 412 near one end of the frame 1, six insertion blocks 411 are evenly spaced on the temple wire 41, and six insertion holes 422 are evenly spaced in the sliding groove 421. Since it is necessary to ensure that at least three insertion blocks 411 are inserted into the insertion holes 422, the length of the temple 4 can be adjusted in four ranges: 130mm, 133mm, 136mm and 139mm.

[0050] Both the foot screw 41 and the foot sleeve 42 are made using a high-precision injection molding process, which makes the production speed of the foot screw 41 and the foot sleeve 42 fast and efficient, and the produced foot screw 41 and foot sleeve 42 are dimensionally accurate.

[0051] The ear tips 42 are made of solid food-grade silicone. Solid food-grade silicone does not produce catalytic phenomena between -30 degrees Celsius and 150 degrees Celsius. Solid food-grade silicone is soft and elastic, which can reduce the pressure on the ears and improve wearing comfort.

[0052] The foot bolt 41 is made of PPSU material, which has the characteristics of high strength and high toughness, and can effectively resist the risk of bending or breaking, maintaining the integrity and stability of the structure.

[0053] The temple cover 42 is provided with heat dissipation holes 423, which can facilitate air circulation, effectively alleviate the stuffiness caused by wearing glasses for a long time, and improve the user's wearing comfort.
