[0002] In daily life, eyeglasses have become an indispensable item for many people, whether they are prescription glasses, farsighted glasses, or sunglasses. With the accelerating pace of life and increasing demands for convenience, traditional eyeglass cases, if not easy to open and close, often fail to meet users' needs for quick access to their glasses. For example, when traveling, engaging in outdoor sports, or in busy work environments, people want to be able to quickly open the eyeglass case to take out their glasses and then quickly close it again. Therefore, quick-opening and closing eyeglass cases have emerged to better meet the expectations of modern, fast-paced lifestyles regarding convenient eyeglass storage.

[0003] Most existing eyeglass cases are connected by a hinge and rely on a frictional structure to maintain a closed state. Opening and closing often requires overcoming a certain amount of friction, making the operation relatively slow. Moreover, after prolonged use, the buckle may wear down, leading to problems such as loose closure.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a quick-opening and closing eyeglass case. Utility Model Content

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1: As shown in the attached document Figure 1 As shown: This utility model provides a quick-opening and closing eyeglass case, including an eyeglass case 1 and a buckle assembly 3;

[0024] As attached Figure 2 As shown: The eyeglass case 1 includes a bottom 101 and a lid 102, with the lid 102 rotatably connected to the rear end face of the bottom 101;

[0025] As attached Figure 3 Appendix Figure 4 and attached Figure 5 As shown: The buckle assembly 3 includes a plug 2, a fixing seat 307, a lower pressing seat 301, a clamping plate 302, a rotating plate 303, a guide plate 306, and a return spring 308. The plug 2 is fixed to the inner bottom surface of the box cover 102, the fixing seat 307 is fixed to the inner wall of the box bottom 101, the return spring 308 is connected to the inner wall of the fixing seat 307, one end of the return spring 308 is pressed down on the lower pressing seat 301, two sets of clamping plates 302 are hinged to the top surface of the lower pressing seat 301, and the side wall of the lower pressing seat 301 is installed with... A reset rotating shaft 304 is provided, and a rotating plate 303 is fixedly installed around the reset rotating shaft 304. A guide rod 305 is fixed on the outer wall of the rotating plate 303. A guide plate 306 is fixed to the inner wall of the fixed base 307. A limiting part 306b is provided on the bottom surface of the guide plate 306. A connecting part 301a is provided on the top walls of both sides of the lower pressure base 301. The connecting part 301a is hinged to the clamping plate 302. A clamping part 302a is provided on the inner wall of the clamping plate 302. The insert 2 is engaged with the clamping part 302a.

[0026] The guide plate 306 has a wedge-shaped structure. The top surface of the guide plate 306 is provided with a first guide part 306a, and the position of the guide rod 305 corresponds to the first guide part 306a. The bottom wall of the guide plate 306 is provided with a second guide part 306c, and the position of the second guide part 306c corresponds to the limiting part 306b.

[0027] By setting the insert 2 in conjunction with the lower pressure seat 301 and the clamping plate 302, when the lid 102 is closed, the insert 2 drives the lower pressure seat 301 to move down. At the same time, the two sets of clamping plates 302 follow and move down. Limited by the inner wall of the fixed seat 307, the two sets of clamping plates 302 rotate toward the insert 2. The clamping part 302a can quickly clamp the insert 2. When the lower pressure seat 301 moves down, it drives the rotating plate 303 and the guide rod 305 to move down. When the guide rod 305 moves down, it is guided by the first guide part 306a. When the guide rod 305 moves down to the bottom of the first guide part 306a, it loses the limitation of the first guide part 306a. At this time, the reset rotating shaft 304 resets, thereby driving the guide rod 305 into the limiting part 306b, thereby locking the position of the lower pressure seat 301. At this time, the lid 102 is locked, realizing the quick closing of the lid 102. The lid is closed tightly and is not easy to loosen.

[0028] When the lid 102 needs to be opened or closed, press the lid 102. At this time, the insert 2 drives the lower pressing seat 301 and the guide rod 305 to continue to move downward. When the guide rod 305 disengages from the limiting part 306b and reaches the second guide part 306c, the guide rod 305 loses its limit, the reset spring 308 resets, and quickly pops the lower pressing seat 301 out. After the lower pressing seat 301 pops out, the two sets of clamps 302 lose their limit, releasing the limit on the insert 2, thereby quickly releasing the fixation on the lid 102 and realizing the opening and closing of the lid 102.

[0029] A limiting rod 102a is fixedly connected to the bottom surface of the box cover 102. A limiting groove 102b is opened on the bottom surface of the limiting rod 102a. An installation frame 101a is fixed to the inner wall of the box bottom 101. A torsion spring 101b is installed on the top wall of the inner wall of the installation frame 101a. One end of the torsion spring 101b is engaged with the limiting groove 102b. By setting the torsion spring 101b, when the box cover 102 loses its limiting position, the torsion spring 101b resets, thereby quickly popping the box cover 102 out.

[0030] As can be seen from the above, when the lid 102 is rotated downwards to close the eyeglass case, the insert 2 fixed to the bottom surface of the lid gradually approaches the latch assembly 3 as the lid moves downwards. After the insert 2 contacts the lower pressure seat 301, it drives the lower pressure seat 301 to move downwards. Since the top surface of the lower pressure seat 301 is hinged with two sets of clamping plates 302, and the lower pressure seat is restricted by the inner wall of the fixed seat 307 during its downward movement, the two sets of clamping plates 302 will rotate in the direction of the insert 2 under the constraint of the inner wall of the fixed seat.

[0031] The clamping part 302a quickly clamps the insert 2, and the rotating plate 303 and guide rod 305 also move downwards. During the downward movement, the guide rod 305 is guided by the first guide part 306a on the top surface of the guide plate 306. When the guide rod 305 moves down to the bottom of the first guide part 306a, it loses the limitation of the first guide part 306a. At this time, the reset rotating shaft 304 resets, driving the guide rod 305 into the limiting part 306b on the bottom surface of the guide plate 306, thereby locking the position of the lower pressure seat 301 and achieving a tight lock on the lid 102.

[0032] When the lid 102 needs to be opened, press the lid 102 by hand. The insert 2 will drive the lower pressure seat 301 and guide rod 305 to continue moving downward. When the guide rod 305 disengages from the limiting part 306b and reaches the second guide part 306c, the guide rod 305 loses its limiting position. The return spring 308 connected to the inner wall of the fixed seat 307 resets, quickly popping the lower pressure seat 301 upward. As the lower pressure seat 301 pops out, the two sets of clamps 302 lose the limiting constraint of the inner wall of the fixed seat 307, thereby releasing the clamp on the insert 2 and quickly releasing the fixation of the lid 102.

[0033] Since the bottom surface of the limiting rod 102a of the bottom surface of the box cover 102 has a limiting groove 102b, and one end of the torsion spring 101b installed on the inner top wall of the mounting frame 101a of the inner wall of the box bottom 101 is engaged with the limiting groove 102b, after the limiting of the insert block 2 by the pressing seat 301 is released, the torsion spring 101b returns to its original position, and the box cover 102 pops out quickly.

[0034] Example 2: Based on Example 1, two sets of first limiting plates 101c are symmetrically fixed on the inner wall of the box bottom 101, and two sets of second limiting plates 102c are symmetrically fixed on the inner wall of the box cover 102; a first wedge-shaped part 101d is provided on the side wall of the first limiting plate 101c, and a second wedge-shaped part 102d is provided on the side wall of the second limiting plate 102c, and the second wedge-shaped part 102d abuts against the first wedge-shaped part 101d.

[0035] As can be seen from the above, when the lid 102 is closed, the second wedge-shaped part 102d abuts against the first wedge-shaped part 101d, which can guide the lid 102 to close accurately to the correct position, and can also play a buffering role during the closing process of the lid 102 to reduce collision.
