Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

Referring to fig. 1 to 4 and 6, the present invention discloses a pair of glasses with fast replaceable lenses, wherein the glasses comprise two articulated temple members 2 at two sides of a frame 1, and the frame 1 comprises two lens frames 11 for mounting lenses 3. The utility model discloses in, be equipped with the caulking groove 12 of block lens in the lens frame 11 respectively, form the intercommunication between two lens frames 11 and locate to form swing joint in the middle part, make the last side 111 of two lens frames 11 link to each other and form the last side 10 of picture frame 1. As shown in fig. 3, in the present embodiment, each lens frame 11 includes an upper side 111, a lower side 112, an outer side 113 and an inner side 114, the two upper sides 111 are connected to form an upper side 10 of the frame, and the upper side 10, the outer side 113, the lower side 112 and the inner side 114 are respectively provided with a groove 12 for engaging with the outer edge of the lens.

Referring to fig. 1 to 7, an upper connecting block 4 having a slot 41 is disposed downward at the middle of the upper edge 10 of the frame, the inner edges 112 of the two lens frames 11 located at the inner sides are connected in an intersecting manner so that the two lenses are located at two sides of the bridge of the nose, a nose pad 5 is connected to the rear side of the joint, and a fastening block 6 is pivoted at the joint and the fastening block 6 is located above the nose pad 5. In order to make the lens clamped in the insertion groove 12 of the lens frame 11 be able to be removed and replaced after the frame is stretched, the clamping pin 61 capable of being clamped in the clamping groove 41 is provided on the clamping block 6, so that the clamping block 6 can be clamped in the clamping groove 41, or the clamping block 6 can be pulled out to remove the clamping groove 41. Thereby through block location or separation between fixture block 6 and draw-in groove 41, drive two lens frame 11 built-up connection or pine take off, lens 3 chucking is in the caulking groove 12 of lens frame 11 or is separated from caulking groove 12 to change lens 3.

In this embodiment, as shown in fig. 2 and 5 to 7, the lower sidewall of the slot 41 is provided with an engaging portion 411, and the front end of the engaging leg 61 is provided with a barb portion 611 for engaging with the engaging portion. The engaging portion 411 may be formed as a step on the lower side wall of the engaging slot 41, a groove 612 is formed in the bottom surface of the engaging leg 61, a barb 611 capable of hooking on the step is formed in front of the groove 612, and the groove 612 is caught on the step. The clamping connection between the clamping foot 61 and the clamping portion 411 can drive the movable connection between the clamping block 6 and the upper connecting block 4. Further, the engaging block 6 may further include a supporting piece 62 protruding above the engaging leg 61, the supporting piece 62 forms a suspension structure, and the supporting piece 62 supports against the upper sidewall of the engaging groove 41 when the engaging leg 61 is engaged with the engaging portion 411, as shown in fig. 5, so that the engaging block 6 is more stably connected to the engaging groove 41.

Go up connecting block 4 and can form a square block, draw-in groove 41 can be at the middle part of last connecting block 4 and form a square through-hole, can upwards be equipped with a square lower connecting block 7 on the junction of the inboard edge of two lens frames 11, as shown in fig. 2, makes fixture block 6 through a pivot pin joint under on connecting block 7, goes up connecting block 4 and lower connecting block 4 and can support each other when the fixture block card goes into the draw-in groove and lean on, as shown in fig. 5.

For the connection of the lens 3, the inserting groove 12 is disposed in the lens frame 11, the rib 13 outside the inserting groove 12 forms an outer frame of the lens frame 11, and the outer frame forms a gap 14 at the connection between the lower side 112 and the inner side 114, as shown in fig. 2 and 4, the lens 3 can be pushed at the gap 14 or used as a yielding space, so that the lens 3 can be conveniently taken out. In this embodiment, the lens 3 is an integrated lens, as shown in fig. 1, the lens 3 can be inserted into the caulking groove 12 when the two lens frames 11 are opened, the middle portion of the lens 3 stops the middle portion of the frame 1, and the upper connecting block 4 and the lower connecting block 7 are located behind the lens 3.

Combine 1 to fig. 7 show, the utility model discloses during the use, when needs change the lens, pull backward or outwards break off with the fingers and thumb fixture block 6 at picture frame rear side middle part, make the block portion 411 of block foot 61 in the last connecting block 4 deviate from, fixture block 6 removes the location from draw-in groove 41, and the higher authority of picture frame 1 is portable, can loosen and take off between two lens frames 11, and the messenger inserts the lens of gomphosis in caulking groove 12 and can separate out gradually, realizes tearing lens 3 out fast. On the contrary, when installing lens 3, utilize to have certain tensile deformation between two lens frames, in lens 3 installation goes into the caulking groove 12 of picture frame, recycle fixture block 6 and last connecting block 4 and realize the block location, two lens frame built-up connection, but lens 3 chucking is in the caulking groove 12 of each lens frame 11 to realize quick replacement lens.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
