Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a free opening and closing structure of temples. Background Art

[0002] The glasses include a frame with lenses and two temples hinged to the studs at both ends of the frame. Under normal conditions, the two temples are overlapped left and right and folded behind the frame. When people need to wear and use the glasses, they have to use their hands to pry the two temples apart and rotate them about 90 degrees respectively, so that the frame can be placed in front of the eyes and the temples can be hung on the ears.

[0003] For example, Chinese patent CN211506074U discloses a pair of glasses with elastically opening and closing temples, comprising a frame, studs arranged at both ends of the frame and temples hinged on the studs, the temples comprising a temple body and a hinged joint connected to one end of the temple body, the hinged joint being hinged to the stud, a spring sheet being detachably connected to the hinged joint, one end of the spring sheet being detachably positioned on the hinged joint, and the other end extending toward the stud to form an elastic end, a side of the stud close to the hinge abutting against a side wall of the elastic end, and when the temple rotates, the stud abuts against the spring sheet and causes it to deform elastically, however, the temples do not have the function of 360-degree adjustment, which reduces the comfort when worn, and are also not suitable for the needs of consumers with different face shapes, reducing the versatility of the glasses, and therefore a temple free opening and closing structure is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a freely opening and closing structure for the temples of the glasses, which has the advantages of 360-degree adjustment, etc., and solves the problem that the temples of the glasses do not have the function of 360-degree adjustment, resulting in reduced comfort when worn, and are not suitable for the needs of consumers with different face shapes, thus reducing the versatility of the glasses.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a freely opening and closing structure of temples, comprising a frame, a connecting block is fixedly connected to the frame, and an adjusting mechanism is arranged on the frame;

[0006] The adjustment mechanism includes a connecting rod fixedly connected to the outer side of the connecting block, a gear fixedly connected to the bottom of the connecting rod, a brake rod provided at the bottom of the gear, a connecting spring fixedly connected to the brake rod, two connecting plates fixedly connected to the brake rod, and limit blocks provided on both connecting plates.

[0007] Furthermore, a connecting through hole is provided on the connecting plate, and the size of the connecting through hole is adapted to the size of the limiting block.

[0008] Further, the size of the gear groove on the gear is adapted to the size of the connecting elastic piece.

[0009] Further, the inside of the gear is slidably connected to the outside of the limiting block.

[0010] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0011] In this temple freely opening and closing structure, by setting an adjusting mechanism, the glasses are provided with an adjusting function, achieving the effect of adjusting the opening and closing angle of the temple. Thus, when the braking rod swings, the connecting elastic piece on the braking rod and the gear groove on the gear switch and position at a 360-degree angle to form the opening angle of the temple, making the wearing comfort higher and more flexible, meeting the needs of consumers with different face shapes. At the same time, when closing the temple, it is not easy to touch the frame, effectively protecting the frame, facilitating the use of the user, and improving the practicability of the glasses.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Embodiment 1, please refer to Figure 1-2 , a temple freely opening and closing structure in this embodiment includes a frame 1, a connecting block 2 fixedly connected to the frame 1, and an adjusting mechanism provided on the frame 1.

[0017] The adjusting mechanism includes a connecting rod 3 fixedly connected to the outside of the connecting block 2, a gear 4 fixedly connected to the bottom of the connecting rod 3, a braking rod 5 provided at the bottom of the gear 4, an activity groove opened at the bottom of the braking rod 5, a plurality of positioning through holes 15 opened on the braking rod 5, a connecting elastic piece 6 fixedly connected to the braking rod 5, and the size of the gear groove on the gear 4 is adapted to the size of the connecting elastic piece 6.

[0018] It should be noted that the connecting elastic piece 6 adjusts its position in the gear groove formed on the gear 4, thereby adjusting the opening and closing angle of the brake lever 5.

[0019] Embodiment 2. Please refer to Figure 1-2 , in this embodiment, two connecting plates 7 are fixedly connected to the brake lever 5. Connecting through holes are formed in the connecting plates 7. Limit blocks 8 are arranged on both of the two connecting plates 7. The size of the connecting through holes is adapted to the size of the limit blocks 8. The inner part of the gear 4 is slidably connected to the outer side of the limit blocks 8.

[0020] It should be noted that when the brake lever 5 swings, the connecting elastic piece 6 on the brake lever 5 and the 360-degree angle switching positioning angle of the gear groove form the opening angle of the temple, making the wearing comfort higher and more flexible, meeting the needs of consumers with different face shapes. At the same time, when the temple is retracted, it is not easy to touch the frame 1, effectively protecting the frame 1.

[0021] The working principle of the above embodiment is as follows: for this freely opening and closing structure of the temple,

[0022] When in use, by setting the adjusting mechanism, the brake lever 5 is connected to the gear 4 through the connecting plate 7 and the limit block 8, so that the connecting elastic piece 6 is inserted into the gear groove formed on the gear 4. When the brake lever 5 is rotated, the connecting elastic piece 6 on the brake lever 5 switches among multiple gear grooves on the gear 4. Thus, when the brake lever 5 swings, the connecting elastic piece 6 on the brake lever and the 360-degree angle switching positioning angle of the gear groove form the opening angle of the temple, making the wearing comfort higher and more flexible, meeting the needs of consumers with different face shapes. At the same time, when the temple is retracted, it is not easy to touch the frame, effectively protecting the frame.
