It should be noted that the invention belongs to a micro-accessory, the size and the moving range of the micro-accessory are suitable for the included angle space between the glasses legs and the lens frame, the size and the position are matched reasonably, the visual field is not influenced, and the related accessories can not contact the skin of a wearer.

Examples 2,

On the basis of embodiment 1, the present embodiment discloses a spectacle frame, as shown in fig. 1 to 6, the spectacle frame comprises a lens frame 1 for fixing lenses, a connecting block 4 is fixedly arranged at the side end of the lens frame 1, a spectacle leg 3 is hinged to the end of the connecting block 4, and the spectacle frame 1 is provided with a nose bridge protection accessory;

as shown in fig. 1 to 6, a first fixing block 6 of the nose bridge protection fitting is fixedly connected with the inner surface of the connecting block, a second fixing block 8 is fixedly connected with one side of the inner surface of the glasses leg 3 on the same side, which faces the lens, the upper surface of the first fixing block is flush with the upper surface of the third fixing block, the first fixing block and the third fixing block are connected through a pull rod 5, and in the process of opening and closing the glasses legs, the pull rod 5 tightens up 2 glasses legs through the acting force of a spring.

In this embodiment, the first fixing block 6 and the second fixing block 8 can be bonded to the contact surface by strong glue, so that the nose bridge protection fitting of the present invention can be adapted to various spectacle frames (requiring lens frames and spectacle legs) by mounting.

Examples 3,

On the basis of embodiment 2, the present embodiment is improved as follows:

the second fixed block 8 and the glasses legs 3 are integrally formed;

the second fixing block 8 is embedded in the glasses legs 3.

In this embodiment, the second fixing block 8 and the glasses legs 3 may be integrally formed by injection molding, and the second fixing block 8 is embedded in the glasses legs 3 and remains integrally formed with the glasses legs, that is, the second fixing block is a part of the glasses legs, and the groove for embedding the guide sleeve 9 is formed on the inner surface of the glasses legs.

Examples 4,

On the basis of the above embodiments, the present embodiment further discloses a method for installing a nose bridge protection fitting, as shown in fig. 1 to 6, including:

step 1, fixedly arranging a first fixing block 6 on the inner surface of a connecting block 4;

step 2, arranging the second fixed block 8 on the side, facing the lens, of the inner surface of the glasses leg corresponding to the first fixed block, and enabling the upper surface of the third fixed block 12 to be flush with the upper surface of the first fixed block 6;

step 3, connecting two ends of the pull rod 5 with the first fixed shaft 7 and the second fixed shaft 14 respectively;

and 4, mounting the nose bridge protection accessory on the other side according to the steps.

In the step 1 and the step 3, the first fixing block 6 and the second fixing block 8 are both bonded with the corresponding mounting positions through super glue.

Examples 5,

This example differs from example 4 only in that:

in the step 3, the second fixing block 8 and the glasses legs are integrated, and the guide sleeve 9 is embedded on the inner surfaces of the glasses legs in a manner of slotting on the inner side surfaces of the glasses legs.

Examples 6,

On the basis of embodiment 4, the present embodiment is improved as follows:

as shown in fig. 5 and 6, in step 2, when the second fixed block is mounted, the strip-shaped hole 13 is located on the side facing the first fixed block.

The principle of use of this embodiment can be seen in fig. 4, in which, according to the position marking line 15 towards one end of the strip-shaped hole when the spring is naturally extended, a theoretical first trajectory line 16 of the marking line 15 can be obtained by rotating around the hinge shaft 18 of the temple, and a theoretical second trajectory line 17 can be obtained by rotating the end of the pull rod around the first fixed shaft 7, and it can be seen that the closest positions of the two trajectory lines are the positions where the spring drives the pull rod and further drives the temple to move, that is, the spring tends to recover the natural extension state no matter whether compressed or extended.

In this embodiment, the strip-shaped hole is located on one side facing the first fixing block, and in the process of unfolding or closing the glasses legs, the spring is always in a traction state and is in a state of maximum tension when contacting with the head of a wearer, and 2 glasses legs tend to be mutually closed, so that the head of a person can be clamped.

Example 7,

On the basis of embodiment 4, the present embodiment is improved as follows:

in the step 2, when the second fixed block is installed, the strip-shaped hole 13 is positioned on one side far away from the first fixed block.

The installation position of the second fixing block 8 of the embodiment is opposite to the direction of fig. 5 and 6 (not shown in the figures), as shown in fig. 4, in the implementation process, the marking line 15 is the end position of the spring in the natural extension state, the spring is always in the contraction state due to the pulling of the pull rod, the end of the pull rod is positioned at one side of the marking line 15 facing the spring, when the glasses legs are opened, the contraction degree of the spring is maximum, and the spring drives the glasses legs to clamp the head of a person due to the principle that the spring tends to reset; similarly, when the glasses legs are closed, the spring still keeps a certain shrinkage state, and the glasses legs are naturally closed.

By combining the embodiments 6 and 7, the embodiment 6 has better beneficial effects, on one hand, the length of the pull rod is reduced, on the other hand, the springs are all positioned in the closed guide sleeve, the stability of the springs is easy to keep, and the hairs of a human body cannot be clamped; in embodiment 7, the spring extends into the sleeve on one side of the strip-shaped hole when naturally extending, the spring is always in a contracted state in the process of opening or closing the glasses legs, and the end part of the pull rod is positioned on one side of the marking line 15 facing the spring, so that the glasses legs can be ensured to realize the function of clamping the head of a person, and the glasses legs can be kept to be closed under the action of the spring force. On the other hand, if the position in which the spring tends to return is between the angle of the open state of the temple and the lens holder, in this case either the temple cannot be closed naturally due to the force of the spring or the temple cannot clamp the head of the user.

Based on the above detailed analysis, the present invention has disclosed embodiments of the related art.
