Problems solved by technology

However, this mechanism can only make the cap nut reciprocate according to the depth length of the cap nut, so the length of the fixed wire must be strictly determined so that the fixed wire can be fastened within its movable range, which is very inconvenient

Embodiment 1

[0025] Referring to Figures 1 to 3, 1 is a lens, 2 is a frame rod, 3 is a fixed wire, and 4 is a tubular screw. In this embodiment, zinc-nickel-nickel copper is used to make the upper chord portion supported by the arc-shaped frame rod 2 on the outer periphery of the lens 1. The metal front frame F (see Figure 1).

[0026] Fasten the fixed line 3 that is not fixed by the frame bar 2 on the outer periphery of the remaining lens to adopt strong and tough stainless steel wire, and one end of the fixed line 3 is spot-welded with a cylindrical member to form a cylindrical anti-off block 31 (see Figure 2).

[0027] At the arc end on the temple side of the frame rod 2, an internal thread cylinder portion 21 that can slidably embed the anti-off block 31 is penetrated, and an inner tube portion 41 that can slidably embed the anti-off block 31 of the fixed wire 3 is provided therein. , The outer circumference of the tubular screw 4 is provided with an external thread 44 that matches the...

Embodiment 2

[0033] Referring to Fig. 4 and Fig. 5, it is the same as Embodiment 1, except that in this embodiment, the plastic front frame F is made of cellulose acetate resin, and at the same time, anti-off blocks 31 are formed at both ends of the fixing line 3 , and the two arc ends of the glasses bridge side and the temple side of the frame rod 2 are respectively provided with internally threaded holes 21 (see FIG. 4 ) for inserting the anti-off block 31 . The fixed wire 3 is a nylon cord, and the end of the cord is melt-molded to form a stopper 31 . Even if the fixed wire 3 is made of a synthetic fiber single-ply cord, since the fixed wire 3 is inserted while adjusting the tension force by screwing in and out of the tubular screw 4, there is no need to worry about the fixing wire 3 being broken due to excessive stretching. Case. In this embodiment, the tubular screw 4 is provided with a linear slit 46 from the opening to the fixing wire hole 43, by means of which, the fixing wire 3 i...

Embodiment 3

[0035] Referring to Fig. 6 and Fig. 7, it is the same as Embodiment 1, except that in this embodiment, an extension 22 is formed on the arc end of the temple bar 2 on the side of the temple, and at the same time behind the extension 22 A connecting portion 5 is provided on the upper portion, and an internal threaded cylindrical portion 51 (see FIG. 6 ) that is slidably embedded in the anti-off block 31 is provided through the upper surface of the connecting portion 5 .

[0036]And from the lens side surface of the connecting part 5, there is a communicating hole 52 communicated with the internal thread cylinder part 51 of the connecting part 5, and the connection hole 52 drawn from the fixing thread hole 43 of the tubular screw 4 of the internal thread cylinder part 51 is inserted. The fixing wire 3 is led out through the communication hole 52, and is wound and hung on the lens 1 (see FIG. 7 ).

[0037] In this way, the lens fixing mechanism of the present invention can be use...

Abstract

The invention relates to a lens fixing mechanism for glasses with a part of frame, mainly comprising a lens and support frame poles arranged at the upper chord or the lower chord, or the left chord and the right chord of the external edge of the lens. The rest external edges of the lens are fastened and fixed through a fixed thread. At least one end of the fixed thread is connected with a column release-stop block. The arc end of the frame pole connected with and opposite to the release-stop block of the fixed thread is provided with an inner thread cylinder which can be embedded into the release-stop block in a sliding way. The release-stop block of the fixed thread is slide-embedded into a tubular thread inner tube which is screwed with the inner thread cylinder positioned at the opposite arc end of the frame pole. The other end of the fixed thread is led from the fixed-thread hole positioned at the bottom of the inner tube and then is embedded into a V-shaped groove positioned on the external edge of the lens, and finally fixedly connected with the other arc end of the frame pole. The invention has the advantages of being easy for demounting and mounting, being capable of fastening the lens even using a non-shrinkable fixed thread without worrying the release of the fixed thread, and being unnecessary to set the length of the fixed thread according to the size of the lens strictly.

Description

technical field [0001] The invention relates to the improvement of the lens fixing structure of spectacles, in particular to a lens fixing mechanism of partial frame spectacles. Background technique [0002] Partial frame glasses, such as half-rim glasses, in which the lens is fixed by a fixing wire composed of a frame rod and a synthetic fiber single strand, are very popular as glasses with excellent fashion and visual performance. [0003] Known part-frame glasses are provided with locking holes at the two arc ends of the frame rod, and the lens can be fixed by embedding the fixing wires locked on these locking holes on the outer periphery of the lens (see Japanese JP-A-10-10472, pages 2 to 11, Figures 1 to 6). However, in the above-mentioned known lens fixing mechanism for some frame glasses, the fixing wire must be clamped first and then the lens is installed. Therefore, a special tool must be used to elongate the fixing wire of a specified length and then insert the fi...
