Abstract
Description
Technical Field
[0001] This utility model belongs to the field of eyeglasses technology, and in particular relates to a temple with an angle adjustment function. Background Technology
[0002] Current eyeglasses typically have a built-in spring mechanism at the back of the temples, designed to adjust the distance between the temples by deforming the spring: in casual wear, the spring causes the temples to open outwards; in sports wear, it causes the temples to close inwards to reduce the angle. However, the force applied by the user when adjusting the temple angle is often difficult to control and varies. In addition, the spring is in a state of high-frequency folding and deformation for a long time, which can easily lead to metal fatigue or structural damage, resulting in loss of elasticity, reduced clamping force or even breakage, seriously affecting the product's lifespan and wearing stability. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a temple with angle adjustment function, including a head and two temples rotatably mounted on the head. The temple includes a front temple and a rear temple rotatably connected to the head. The feature is that an elastic component and a positioning component are provided between the front temple and the rear temple. The elastic component has an energy storage state and an energy release state. The rear temple can be pulled or retracted axially relative to the front temple. In the energy storage state, the rear temple moves away from the front temple and can rotate relative to the front temple to adjust the angle between the two rear temples. In the energy release state, the rear temple retracts and fits against the front temple. When the rear temple retracts and fits against the front temple, the positioning component locks the rear temple at the current rotation angle.
[0004] The present invention is further configured such that: the elastic component includes a fixed rod fixedly disposed in the front temple and a spring sleeved on the fixed rod; a limiting block is fixedly fixed at the end of the fixed rod away from the front temple; an movable hole adapted to the limiting block is opened on the rear temple; a hollow retaining ring fixedly connected to the rear temple is provided in the movable hole; the hollow inner wall of the hollow retaining ring is adapted to the rod body of the fixed rod; and the spring is located between the limiting block and the hollow retaining ring.
[0005] The present invention is further configured such that: the positioning component includes a hollow column movably sleeved on a fixed rod and at least two positioning rods fixedly disposed on the outer circumference of the hollow column; the hollow column is fixedly connected to a hollow retaining ring; a receiving groove for accommodating the hollow column is provided on the front temple; and a positioning groove adapted to the positioning rod is provided on the side wall of the receiving groove.
[0006] A further feature of this invention is that the radius of the limiting block is greater than the radius of the fixing rod.
[0007] The beneficial effects of this utility model are as follows: When it is necessary to switch the temples from a casual wearing state to a sports wearing state, first pull the rear temples away from the front temples. At this time, the positioning rod of the positioning component separates from the positioning groove. Then, rotate the rear temples so that the positioning rod aligns with another positioning groove, making the angle between the two rear temples smaller. Then, release the rear temples, and the elastic force of the elastic component pushes the positioning rod into the positioning groove for positioning. The rear temples fit against the front temples, thereby reducing the angle between the two rear temples, making it convenient to wear during sports. The combination of the elastic component and the positioning component avoids the problem in the existing system where the spring is in a state of high-frequency folding and deformation for a long time, which is prone to metal fatigue or structural damage, leading to elastic failure, reduced clamping force or even breakage, seriously affecting the service life and wearing stability of the product.

[0008] Appendix Figure 1 This is a schematic diagram of the structure of this utility model; Appendix Figure 2 This is a schematic diagram of the elastic component of this utility model installed on the rear temple. Appendix Figure 3 This is a schematic diagram of the positioning groove of this utility model being formed on the front temple of the mirror. Appendix Figure 4 This is a schematic diagram of the positioning rod of this utility model set on the hollow column. Detailed Implementation
[0009] according to Figure 1-4This embodiment discloses a temple with angle adjustment function, including a head 1 and two temples 2 rotatably mounted on the head 1. Each temple 2 includes a front temple 3 and a rear temple 4 rotatably connected to the head 1. An elastic component and a positioning component are provided between the front temple 3 and the rear temple 4. The elastic component has an energy storage state and an energy release state. The rear temple 4 can be pulled or retracted axially relative to the front temple 3. In the energy storage state, the rear temple 4 moves away from the front temple 3 and can rotate relative to the front temple 3 to adjust the angle between the two rear temples. In the energy release state, the rear temple 4 retracts and fits against the front temple 3. When the rear temple 4 retracts and fits against the front temple 3, the positioning component locks the rear temple 4 at the current rotation angle. In the desired casual wearing state... When switching from the down position to the sports wearing position, first pull the rear temple away from the front temple. At this time, the positioning rod of the positioning component separates from the positioning groove. Then rotate the rear temple so that the positioning rod aligns with another positioning groove, reducing the angle between the two rear temples. Then release the rear temple, and the elastic force of the elastic component pushes the positioning rod into the positioning groove for positioning. The rear temple fits against the front temple, thus reducing the angle between the two rear temples, making it easier to wear during sports. The combination of the elastic component and the positioning component avoids the problem of the spring being in a state of high-frequency folding and deformation for a long time, which is prone to metal fatigue or structural damage, leading to elastic failure, reduced clamping force or even breakage, seriously affecting the product's service life and wearing stability.
[0010] The present invention is further configured such that: the elastic component includes a fixed rod 5 fixedly disposed within the front temple 3 and a spring 6 sleeved on the fixed rod 5. By setting the spring, a rebound force is generated when the rear temple moves away from the front temple. After the rear temple is adjusted to the correct angle, the rebound force causes the positioning component to engage again, facilitating positioning. A limiting block 7 is fixed to one end of the fixed rod 5 away from the front temple 3. An movable hole 8 adapted to the limiting block 7 is provided on the rear temple 4. A hollow retaining ring 9 fixedly connected to the rear temple 4 is provided in the movable hole 8. The hollow inner wall of the hollow retaining ring 9 is adapted to the rod body of the fixed rod 5. The spring 6 is located between the limiting block 7 and the hollow retaining ring 9. By setting the limiting block and the spring within the rear temple, when the rear temple moves away from the front temple, the hollow retaining ring contacts the spring and plays a limiting role, preventing the rear temple from completely separating from the front temple.
[0011] The present invention is further configured such that: the positioning component includes a hollow column 10 movably sleeved on the fixed rod 5 and at least two positioning rods 11 fixedly disposed on the outer circumference of the hollow column 10. The hollow column 10 is fixedly connected to the hollow retaining ring 9, so that the rear temple can move together with the hollow column and the positioning rods when it moves. The front temple 3 is provided with a receiving groove 12 for accommodating the hollow column 10. The fixed rod is located in the receiving groove. The side wall of the receiving groove 12 is provided with a positioning groove 13 adapted to the positioning rod 11. When the rear temple moves away from the front temple, the positioning rod disengages from the positioning groove. When the rear temple rotates, it drives the positioning rod to correspond with another positioning groove. When the rear temple retracts, the positioning rod is located in the positioning groove, which prevents the rear temple from rotating and plays a positioning role.
[0012] The present invention is further configured such that the radius of the limiting block 7 is greater than the radius of the fixing rod 5, thereby limiting the spring.
[0013] The working principle of this utility model: When switching the temples from casual to sporty wear: Pull the rear temple away from the front temple. As the rear temple moves away from the front temple, it will cause the positioning rod on the hollow post to disengage from the positioning groove. At this time, the spring is compressed. Then rotate the rear temple to reduce the angle between the two rear temples. When the rear temple rotates, it also drives the positioning rod to rotate, so that the positioning rod aligns with the other positioning groove. Then release the rear temple. The rear temple, through the elastic force of the spring, pushes the positioning rod into the positioning groove for positioning. The rear temple fits against the front temple, thereby reducing the angle between the two rear temples.
[0014] The above description is only a preferred embodiment of the present utility model. The present utility model is not limited to the above-described embodiments. Any modifications, alterations or equivalent substitutions made by those skilled in the art based on the above description shall fall within the scope of protection of the present utility model.
