[0014] Reference Figures 1 to 3 The embodiments of the utility model are further described.

[0015] The utility model discloses a pair of glasses with replaceable temples, comprising a frame 1 and temple assemblies 2 respectively located on both sides of the frame 1, wherein the temple assembly 2 consists of a temple connecting block 20 and temples 21, one end of the temple connecting block 20 is hingedly fixed on the frame 1, and the other end is provided with an insertion groove 200, a mounting groove 201 connected to the insertion groove 200 is provided on the inner side of the temple connecting block 20, a gear 22 for rotational matching is provided in the mounting groove 201, a metal plug rod 210 adapted to the plug groove 200 is provided at one end of the temple 21, and tooth grooves 211 meshing with the gear 22 for transmission are arranged on the metal plug rod 210. The upper end of the temple connecting block 20 is penetrated with a fastening rod 23 extending into the mounting groove 201, the gear 22 in the mounting groove 201 is rotatably matched with the fastening rod 23, the lower end of the fastening rod 23 is threadedly matched with the bottom wall of the mounting groove 201, and the upper end of the fastening rod 23 is provided with a screwing head 230. The diameter of the screwing head 230 is larger than the diameter of the fastening rod 23, and the circumference of the screwing head 230 is provided with anti-slip vertical lines 231.

[0016] Furthermore, in order to facilitate people to adjust the fastening rod 23, the upper end of the temple connecting block 20 is also provided with a circular groove 202 for the screw head 230 to be embedded, and the circular groove 202 is opened at one end close to the inner side of the temple connecting block 20.

[0017] Furthermore, in order to improve the stability between the temple 21 and the metal rod 210 during production, the temple 21 is integrally molded outside the metal rod 210 through an injection molding process.

[0018] Working principle: When the temple 21 needs to be replaced, the screw head 230 is turned so that the screw head 230 will be disengaged from the fixation on the gear 22, and then people can apply force to pull the temple 21, so that the metal plug rod 210 of the temple 21 will be disengaged from the insertion groove 200 of the temple connecting block 20. During the process of the metal plug rod 210 being disengaged, the gear 22 will rotate around the fastening rod 23, thereby realizing that the temple 21 is completely disengaged from the temple connecting block 20.

[0019] When the temple 21 is separated from the temple connecting block 20, people can hold the newly replaced temple 21 and then re-insert it into the insertion slot 200 of the temple connecting block 20. At this time, the metal plug rod 210 of the temple 21 will form a meshing transmission match with the gear 22, so that the metal plug rod 210 will be initially stuck in the insertion slot 200. Then people can turn the screw head 230, so that the screw head 230 will drive the fastening rod 23 to rotate downward, so that the screw head 230 will press the temple connecting block 20. When the screw head 230 presses the temple connecting block 20, the gear 22 in the installation slot 201 will be squeezed by the squeezing force of the screw head 230 and stuck in the installation slot 201 for limiting, so that the gear 22 will stably fix the metal plug rod 210 of the temple 21 in the insertion slot 200 of the temple connecting block 20, and will not be easily separated from the temple connecting block 20 by external force.

[0020] In addition, people can also adjust the length of the glasses leg 21 through the meshing transmission cooperation between the metal rod 210 and the gear 22, so as to improve the wearing comfort.

[0021] When replacing the glasses legs 21 of the practical glasses, the glasses legs can be quickly replaced without using tools, the operation is simple and convenient, and the glasses are very practical.

[0022] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
