DETAILED DESCRIPTION

[0022] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] Example:

[0024] like Figures 1 to 5 As shown, the utility model discloses a pair of glasses with adjustable temple length, comprising a frame 1 and temples 2, wherein the temples 2 comprise, from front to back, a connecting portion 21, an extension portion, and a tail portion 23. In this structure, the front end of the connecting portion 21 is used to be connected to the frame 1, while the extension portion is fixedly connected to the front end of the tail portion 23 and is slidably arranged on the rear end of the connecting portion 21. In addition, a displacement mechanism for adjusting the sliding position of the extension portion is provided on the temples 2.

[0025] This structure uses a displacement mechanism to control the sliding position of the extension portion, thereby changing the overall length of the temple 2. The sliding logic of the extension portion is as follows: when the overall length of the temple 2 needs to be increased, the extension portion slides backward on the connecting portion 21, thereby moving the tail portion 23 away from the connecting portion 21; when the overall length of the temple 2 needs to be shortened, the extension portion slides forward on the connecting portion 21, thereby moving the tail portion 23 closer to the connecting portion 21.

[0026] The sliding scheme of the extension part is as follows: the extension part includes a long strip-shaped supporting wall 22, and correspondingly, a sliding groove 211 is opened on the connecting part 21 for the supporting wall 22 to slide forward and backward.

[0027] The specific structure of the displacement mechanism can be: the displacement mechanism includes a mounting plate 241 fixedly arranged at the front end of the tail portion 23 and a clamping plate 242 connected to the mounting plate 241. At the same time, a receiving groove 212 for accommodating the mounting plate 241 and the clamping plate 242 is provided at the rear end of the connecting portion 21. In this structure, the clamping plate 242 is slidably arranged on one side of the mounting plate 241 and its sliding direction is perpendicular to the sliding direction of the supporting wall 22. In addition, a plurality of clamping blocks 213 are arranged in sequence from front to back on the side wall of the accommodating groove 212 facing the sliding direction of the clamping plate 242. Correspondingly, a clamping groove 243 for engaging with the clamping block 213 is provided on the clamping plate 242. Finally, a first elastic supporting member 244 for pushing the clamping plate 242 toward the clamping block 213 is provided between the mounting plate 241 and the clamping plate 242. The first elastic supporting member 244 can be a spring.

[0028] The working principle of this structure is that when the slot 243 on the snap-in plate 242 is aligned with the block 213, the elastic supporting member can push the snap-in plate 242 until the slot 243 is engaged with the block 213. At this time, since the front and rear positions of the snap-in plate 242 are fixed by the block 213, the supporting wall 22 cannot move forward and backward. That is to say, when the slot 243 on the snap-in plate 242 is engaged with the block 213, the overall length of the temple 2 is fixed. When the snap-in plate 242 slides in the opposite direction until the block 213 exits the slot 243, the supporting wall 22 can slide again, and the overall length of the temple 2 can be adjusted.

[0029] In order to facilitate people to control the clamping plate 242, a pressing groove 214 is provided on the outer wall of the connecting part 21, and the pressing groove 214 is opposite to the sliding direction of the clamping plate 242. A push plate 245 is slidingly arranged in the pressing groove 214, and the sliding direction of the push plate 245 is consistent with the sliding direction of the clamping plate 242. A supporting column 246 is fixedly connected to the push plate 245, and the free end of the supporting column 246 extends into the accommodating groove 212 and is slidably arranged in the accommodating groove 212. In this structure, the free end of the supporting column 246 is used to resist the clamping plate 242. In addition, a second elastic supporting member 247 is also provided in the pressing groove 214. The second elastic supporting member 247 is an arc-shaped elastic metal sheet. The second elastic supporting member 247 is used to push the push plate 245 in a direction away from the card block 213.

[0030] The working principle of this structure is: when the length of the temple 2 needs to be adjusted, the push plate 245 can be pressed first. At this time, the supporting column 246 on the push plate 245 can push the clamping plate 242 to move. When the clamping groove 243 on the clamping plate 242 is separated from the clamping block 213, the supporting wall 22 can slide back and forth to change the overall length of the temple 2. When the temple 2 moves to the appropriate position, the push plate 245 is released, and the clamping plate 242 will be reset, so that the clamping block 213 is re-engaged with the clamping groove 243, thereby fixing the overall length of the temple 2.

[0031] In this structure, the function of the second elastic supporting member 247 is that when the push plate 245 is released, the second elastic supporting member 247 further applies a thrust to the push plate 245 on the basis of the clamping plate 242 to smoothly reset the push plate 245 .

[0032] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
