Detailed Description

to facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

Referring to fig. 1 to 5, a preferred embodiment of the present invention is:

As shown in fig. 1, a pair of glasses capable of replacing different lenses comprises a glasses frame, glasses legs 1 and a nose support frame 4, wherein the nose support frame 4 is provided with a notch 411; the picture frame comprises a connecting block 2 and a flexible belt 3, and the connecting block 2 is provided with a through hole 6; one end of each glasses leg 1 is fixed on the connecting block 2; the flexible belt 3 is provided with a mounting groove 5, one end of the flexible belt 3 is fixed on the connecting block 2, the other end of the flexible belt passes through the through hole, and the flexible belt 3 passes through the gap 411; the picture frame is enclosed by connecting block 2, flexible band 3 and nose and holds in the palm support frame 4 jointly and forms. The material of the flexible strip 3 may be a soft plastic or rubber.

The flexible belt 3 is internally embedded with soft metal which is easy to generate plastic deformation. Plastic deformation is a deformation that is not self-recoverable. After the engineering material and the member are loaded beyond the elastic deformation range, permanent deformation occurs, that is, after the load is removed, unrecoverable deformation, or residual deformation, is generated, namely plastic deformation. Metals, plastics, etc. all have varying degrees of plastic deformability, and factors that affect plastic deformability include the yield strength of the material and its cross-sectional area. In this embodiment, the soft metal is a plastic material, and the plastic material may be pure copper and pure aluminum, both of which have good plasticity. The cross-sectional diameter of the soft metal is 0.5-1 mm, the yield strength of pure copper is 60Mpa, and the yield strength of pure aluminum is 30Mpa, so that the yield stresses of pure copper and pure aluminum are 12N-47N and 6N-24N respectively in the diameter range. If the soft metal is pure copper, plastic deformation can be generated by applying a force of about 1.2-4.7 kg; if the soft metal is pure aluminum, it can be plastically deformed by applying a force of about 0.6 to 2.4 kg. Preferably, a pure copper metal with a cross-sectional diameter of 0.8mm is selected, which is plastically deformed by a force of less than 47N and has a stability such that it is not easily deformed by the weight of the lens or other external factors. The diameter of the soft metal may be 0.5mm or 1mm, and the profit of plastic deformation may be 12N and 47N, respectively. Form flexible frame through inlaying soft metal on flexible area 3, this flexible frame can set to the shape of corresponding lens according to the lens of difference to have certain stability, thereby realize the change to different lenses.

The side face of the connecting block is provided with a bolt (not shown in the figure), the bolt is an adjustable bolt, and the flexible belt 3 passing through the connecting block 2 can be locked through the bolt so as to ensure the stability of the lens.

As shown in fig. 3 and 4, the bottom of the connecting block 2 is provided with a first belt groove 8, and the first belt groove 8 is connected with the bottom of the through hole 6. First trough of belt 8 mainly used deposits unnecessary flexible area body, imbeds the flexible area and can make the wholeness of picture frame stronger also more pleasing to the eye in the first trough of belt 8. The bottom side of the glasses leg 1 is provided with a second belt groove 9, the second belt groove 9 is communicated with the first belt groove 8, and the part of the flexible belt 3 penetrating through the through hole 6 can be embedded in the first belt groove 8 and the second belt groove 9. The first belt groove 8 and the second belt groove 9 are respectively adapted to the width and the thickness of the flexible belt 3, so that the flexible belt 3 can be stably fixed in the belt grooves and cannot fall off.

As shown in fig. 5, the nose pad support frame 4 includes two support columns 42 and two support clips 41, the two support clips 41 are respectively fixed at two ends of the support columns 42, and the notch 411 is disposed on the support clips. The supporting clip 41 has elasticity, and the notch 411 has a shape of hourglass cross section with two sides gradually reduced towards the middle. The supporting clip 41 is made of elastic material, such as rubber elastomer or nylon, and has the advantages that no additional clamping device is needed, and the flexible belt can be locked by opening the gap to a size that the flexible belt can pass through and loosening the gap. The notch 411 has two channels, the inner channel being used to secure the flexible strap 3, and the outer channel being used to secure the lens so that it is not easily loosened.

As shown in fig. 3 and 4, the temple bar 1 is connected to the connecting block 2 by means of a hinge structure 7. The advantage of using a hinge is that it is easy to disassemble and can be folded through the hinge position when not wearing glasses, thus saving space. The hinge structure 7 comprises a first support column 71 and a second support column 72, one end of the first support column 71 is fixed on the connecting block 2, one end of the second support column 72 is fixed on the temple 1, and the other end of the first support column 71 and the other end of the second support column 72 are rotatably connected through a pin 73.

When carrying out the change of lens, loosen the bolt, take out flexible band 3 to break off and to take off the lens after supporting clamp 411 off with the fingers and thumb, during the lens of renewal, place new lens in suitable position, through the shape and the size with the flexible band adjustment become new scene piece, connecting block 2, flexible band 3 and supporting clamp 411 constitute new picture frame jointly, and the bolt of connecting block 2 sides plays the effect of locking picture frame, with this stability of guaranteeing the lens. Excess flexible band 3 may be placed in the first strap channel 8 and the second strap channel 9 by a second fold to ensure the aesthetic appearance of the eyeglasses.

While the invention has been described in conjunction with the specific embodiments set forth above, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations that fall within the spirit and scope of the appended claims.
