[0002] In the past, when people had blurred vision, they would use glasses or magnifying glasses to see things. Glasses and magnifying glasses each have their own advantages. Glasses are more portable than magnifying glasses, and magnifying glasses can avoid the fatigue caused by pressure on the head after wearing glasses for a long time. However, in daily life, magnifying glasses have gradually withdrawn from the scope of common items in people's homes, and the rotation mode of the temples of most glasses is relatively simple. Glasses can only be used in a head-mounted state. This has led to some myopic people insisting on putting glasses on their ears and nose bridges in order to see things clearly, even if they are tired of wearing them. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] like Figures 1 to 4 As shown, the utility model discloses a hand-held glasses frame, comprising a frame 1 and temples 2, wherein a rotating shaft 3 is rotatably provided at the rear end of the frame 1, and the rear end of the rotating shaft 3 is rotatably connected to the temples 2. In this structure, the rotation direction of the temples 2 is horizontal compared with the frame 1, and the rotation direction of the rotating shaft 3 is perpendicular to the rotation direction of the temples 2, that is, the rotation direction of the temples 2 is used to meet the expansion and closing of the temples 2 in the state of head-mounted glasses, and the rotation direction of the rotating shaft 3 is used to meet the downward expansion or upward folding of the temples 2 in the state of hand-held glasses. In addition, a rotation limiting mechanism for the rotating shaft 3 is provided between the frame 1 and the rotating shaft 3, and the rotation limiting mechanism The control mechanism includes a special-shaped block 31 fixedly arranged on the rotating shaft 3 and a special-shaped groove 11 opened in the frame 1, and the special-shaped block 31 is slidably arranged in the special-shaped groove 11. In this structure, the temple 2 is linked with the special-shaped block 31, and the temple 2 is rotated to make the special-shaped block 31 exit the special-shaped groove 11. The working principle of this structure is that when the special-shaped block 31 is embedded in the special-shaped groove 11, the temple 2 can only rotate the temple 2 in the head-mounted glasses state, but when the temple 2 is rotated to a certain angle, the temple 2 can drive the special-shaped block 31 to exit the special-shaped groove 11. At this time, the temple 2 can swing downward, turning the glasses frame 1 into the structural form required for hand-held glasses.

[0023] The linkage scheme between the temple 2 and the rotating shaft 3 is specifically as follows: a rotating groove 12 is opened in the frame 1, the rear end of the rotating groove 12 extends backward to the rear end surface that passes through the frame 1, the front end of the rotating groove 12 is connected to the special-shaped groove 11, and the rotating shaft 3 is rotatably set in the rotating groove 12. The temple 2 rotates to make the rotating shaft 3 drive the special-shaped block 31 to slide out of the special-shaped groove 11.

[0024] Furthermore, a rotating hole 21 is provided on the temple 2 in the longitudinal direction. At the same time, a rotating rod 32 inserted into the rotating hole 21 is provided on the rotating shaft 3. In this structure, a 180° arc-shaped side wall 22 is formed on the front end side wall of the temple 2. The distance between the axis of the arc-shaped side wall 22 and the rotating hole 21 is not less than the stroke length required for the special-shaped block 31 to exit the special-shaped groove 11.

[0025] At the same time, a reset mechanism for pulling the special-shaped block 31 back into the special-shaped groove 11 is provided in the frame 1, and the setting scheme of the reset mechanism is as follows:

[0026] A sliding groove 13 connected to the special-shaped groove 11 is provided in the frame 1, and the sliding groove 13 is located at the front end of the special-shaped groove 11. The reset mechanism includes a cylinder 33 extending laterally and an elastic pusher 34, wherein the cylinder 33 is fixedly arranged at the front end of the special-shaped block 31 and is slidably arranged between the sliding groove 13 and the special-shaped groove. The elastic pusher 34 is used to push the cylinder 33 forward in the sliding groove 13, and the elastic pusher 34 is a spring.

[0027] The working principle of the above structure is: the rotation center of the temple 2 is eccentrically set compared to the arc-shaped side wall 22, so that when the temple 2 is closed in the state of head-mounted glasses, due to the lengthening of the distance between the rotating hole 21 and the rear end of the frame 1, the temple 2 will drive the rotating shaft 3 to slide backward, and thereby make the special-shaped block 31 withdraw from the special-shaped groove 11. At this time, the temple 2 can be rotated downward to meet the shape change required by the handheld glasses frame 1. When the temple 2 is rotated upward until the temple 2 is folded at the rear end of the frame 1, if the temple 2 is rotated in the horizontal direction, the spring can drive the special-shaped block 31 to embed into the special-shaped groove 11, and the temple 2 can only be rotated in the horizontal direction.

[0028] In order to prevent the shaft 3 from being separated from the temple 2 during the backward sliding process, a supporting plate 35 is provided at the front end of the cylinder 33 . Meanwhile, in this structure, a spring supporting plate is provided between the rear end of the sliding slot 13 and the rear end of the supporting plate 35 .

[0029] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
