Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, and in particular to a detachable spring temple. Background Technology

[0002] As a common tool for correcting vision or protecting the eyes, the structure of the temples of eyeglasses directly affects wearing comfort, stability, and lifespan.

[0003] Traditional temples use a fixed bending design, relying on manual adjustment of the temple body curvature to fit the head circumference. This can easily lead to metal fatigue or plastic deformation due to excessive bending. After long-term use, problems such as loosening and clamping the head may occur. In addition, the temples are prone to slipping off during vigorous exercise, sweating, or head shaking, requiring frequent adjustment and affecting the user experience. At the same time, without a cushioning structure, external impacts (such as squeezing or dropping) will be directly transmitted to the connection between the frame and the temple, which can easily lead to hinge breakage or temple deformation. Summary of the Invention

[0004] The present invention aims to solve the existing technical problem by providing a detachable spring temple that can automatically adjust to the shape of the head without requiring manual adjustment of the temple body's curvature. This avoids the pressure or looseness caused by the temple body being fixed and bent, and can automatically adapt to different head circumferences, ensuring the stability of the glasses when worn.

[0013] The beneficial effects of this utility model are:

[0014] Compared with the prior art, the positioning screw of the detachable spring temple of this utility model is screwed into the first screw hole of the temple body. Therefore, when the temple body is subjected to force and moves to the right, the positioning screw moves synchronously. At this time, the positioning screw will push the pressure plate of the sliding member to the right, so that the sliding plate of the sliding member moves to the right along the guide axis. The spring is located between the sliding plate and the limiting head. At this time, the spring is compressed and generates elastic force, so that the temple body has elasticity. With the temple body itself having elasticity, there is no need to manually adjust the curvature of the temple body. The elastic temple body can automatically adjust according to the shape of the head, avoiding the pressure or looseness caused by the fixed bending of the temple body. It can automatically adapt to different head circumferences and ensure the stability of the glasses when wearing them.

[0015] Compared with the prior art, the sealing ring of the detachable spring temple with the structure of this utility model can effectively ensure the sealing of the gap between the inner wall of the left end of the receiving hole and the outer wall of the buffer seat. It can effectively prevent external impurities from entering the gap between the inner wall of the receiving hole and the outer wall of the buffer seat, which would increase the friction between the two and cause the temple body to slide and get stuck. It can effectively ensure the elasticity of the temple body. At the same time, the presence of the limiting tube can effectively ensure the stability of the sealing ring by restricting the limiting part, and prevent the sealing ring from coming out of the sealing groove due to the pulling force generated when the temple body slides.

[0023] The buffer seat 4 has symmetrical notches 16 on the upper and lower sides of the right side; the sliding member 13 is composed of a sliding plate 1301 that fits against the right end face of the buffer seat 4 and a pressure plate 1302 that matches the notch 16. The pressure plate 1302 is located at the upper and lower ends of the sliding plate 1301; the sliding hole 14 is located at the center of the pressure plate 1302, and the left end of the spring 15 presses against the right side wall of the pressure plate 1302.

[0024] The right end of the mirror frame post 1 is provided with a hinge groove 17 that matches the hinge joint 5; the hinge joint 5 is provided with a hinge hole 18; the lower surface of the mirror frame post 1 is provided with a second countersunk hole 19 that communicates with the hinge hole 18; the upper surface of the mirror frame post 1 is provided with a second screw hole 20 that communicates with the hinge hole; a hinge screw 21 passes through the first countersunk hole 8 and the hinge hole 18 in sequence and is screwed into the second screw hole 20.

[0025] The inner wall of the left end of the receiving hole 3 is provided with an annular sealing groove 22; a sealing ring 23 is provided in the sealing groove 22 and fits against the inner wall on its right side; an annular limiting part 24 extends to the left from the outer edge of the left end face of the sealing ring 23; a limiting structure matching the limiting part 24 is provided at the left end of the temple body 2.

[0029] The method of using this utility model is as follows:

[0030] Since the positioning screw 11 is screwed into the first screw hole 9 of the temple body 2, when the temple body 2 is subjected to force and moves to the right, the positioning screw 11 moves synchronously. At this time, the positioning screw 11 will push the pressure plate 1302 of the sliding member 13 to the right, so that the sliding plate 1301 of the sliding member 13 moves to the right along the guide shaft 6. The spring 15 is located between the sliding plate 1301 and the limiting head 7. At this time, the spring 15 is compressed and generates elastic force, so that the temple body 2 becomes elastic. When the temple body 2 itself is elastic, there is no need to manually adjust the curvature of the temple body 2. The elastic temple body 2 can automatically adjust according to the shape of the head, avoiding the pressure or looseness caused by the fixed bending of the temple body 2. It can automatically adapt to different head circumferences and ensure the stability of the glasses when worn.

[0031] The buffer seat 4 has symmetrical notches 16 on the upper and lower right sides. The pressure plate 1302 matches the notches 16. The notches 16 can be used to accommodate the presence of the pressure plate 1302, avoiding the situation where the pressure plate occupies too much space and makes it difficult to install other components into the receiving hole 3.

[0032] The right end of the frame post 1 is provided with a hinge groove 17 that matches the hinge joint 5. The hinge joint 5 is provided with a hinge hole 18. The lower surface of the frame post 1 is provided with a second countersunk hole 19 that communicates with the hinge hole 18. The upper surface of the frame post 1 is provided with a second screw hole 20 that communicates with the hinge hole 18. A hinge screw 21 passes through the first countersunk hole 8 and the hinge hole 18 in sequence and is screwed into the second screw hole 20. This fixing method can not only ensure the hinged state between the frame post 1 and the temple body 2, but also quickly complete the disassembly between the frame post 1 and the temple body 2 by simply unscrewing the hinge screw 21 from the first screw hole 9 and pulling it out from the hinge hole 18, which is conducive to the replacement and maintenance of the temple body 2.

[0033] The presence of the sealing ring 23 can effectively ensure the sealing of the gap between the inner wall of the left end of the receiving hole 3 and the outer wall of the buffer seat 4, effectively preventing external impurities from entering the gap between the inner wall of the receiving hole 3 and the outer wall of the buffer seat 4, which would increase the friction between the two and cause the temple body 2 to slide and get stuck, thus effectively ensuring the elasticity of the temple body 2.

[0034] The presence of the limiting tube 26 can effectively ensure the stability of the sealing ring 23 by restricting the limiting part 24, and prevent the sealing ring 23 from coming out of the sealing groove 22 due to the pulling force generated when the temple body 2 slides.

[0035] The limiting ring 25 is fixed to the temple body 2 by several fixing screws 27. This fixing method facilitates the disassembly and assembly of the limiting ring 25 and the limiting tube 26, thereby facilitating the disassembly and assembly of the sealing ring 23.

[0036] The outer wall of the limiting tube 26 is provided with several third screw holes 28 evenly distributed in a circle. The outer wall of the temple body 2 is provided with several third countersunk holes 29 coaxial with the third screw holes 28. The limiting part 24 is provided with several connecting holes 30 coaxial with the third screw holes 28. The third countersunk holes 29 are connected to the third screw holes 28 through the connecting holes 30. A limiting screw 31 passes through the third countersunk hole 29 and the connecting hole 30 in sequence and is screwed into the third screw hole 28. The presence of the limiting screw 31 can further fix the position of the limiting part 24 and further prevent the sealing ring 23 from coming out of the sealing groove 22.

[0037] The guide shaft 6 has a fourth screw hole 32 on its right end face, and the left end face of the limiting head 7 has a screw connection part 33 that is screwed into the fourth screw hole 32. This fixing method not only facilitates the disassembly and assembly of the limiting head 7, but also facilitates the disassembly and assembly of the spring 15.
