Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a novel pair of glasses, see figure 1, comprises a glasses frame 1 and lenses 2. The spectacle frame 1 includes a connecting frame 11 for connecting the lenses 2 and temples 12 hinged to both ends of the connecting frame 11.

Referring to fig. 2, the connection blocks 3 are fixed to both ends of the connection frame 11. One end of the temple 12 close to the connecting block 3 is fixed with a matching block 121, and the number of the matching blocks 121 is two and is respectively arranged at the top end and the bottom end of the connecting block 3. The connection block 3 includes a fixing portion 32 fixedly connected to the connection frame 11 and a connecting portion 31 provided between the two fitting blocks 121. The fitting block 121 is provided with a screw stub 4 penetrating the fitting block 121 and the connecting portion 31. The screw stub 4 is rotatably connected with the connecting part 31 and is in threaded connection with the matching block 121, so that the connection and the hinge joint of the glasses leg 12 and the connecting frame 11 are realized.

Referring to fig. 3 and 4, a vertical through hole 311 is formed in the middle of the connecting portion 31 of the connecting block 3, and the through hole 311 makes the cross section of the connecting portion 31 circular. The connecting portion 31 is composed of a bottom block 34 and a top block 33, wherein the top block 33 is fixedly connected with the fixing portion 32.

A conical protrusion 342 is fixed on one side of the bottom block 34 close to the top block 33, and the radius of the conical protrusion 342 is smaller than the outer diameter of the bottom block 34; one side of the top block 33 close to the bottom block 34 is provided with a conical groove 332 matched with the conical protrusion 342; when the top block 33 and the bottom block 34 abut, the tapered protrusion 342 abuts the tapered groove 332. A clamping block 341 is fixed on one side of the bottom block 34 close to the top block 33, and a clamping groove 331 for the clamping block 341 to insert is formed at one end of the top block 33 close to the bottom block 34.

The conical protrusion 342 is provided with a plurality of mounting holes 3421 (the number of the mounting holes 3421 is plural), a small steel ball 3422 with a radius slightly smaller than that of the mounting hole 3421 is disposed in the mounting hole 3421, the length of the mounting hole 3421 is smaller than the diameter of the small steel ball 3422, and the small steel ball 3422 can slide in the mounting hole 3421. A limiting ring 3423 is fixed at one end of the mounting hole 3421 close to the through hole 311, and the inner diameter of the limiting ring 3423 is slightly smaller than the radius of the small steel ball 3422, so as to prevent the small steel ball 3422 from sliding out of the end of the mounting hole 3421 close to the through hole 311.

The top block 33 has an annular cavity 334 formed therein. The cavity 334 is located at the location of the tapered slot 332 and allows the sidewalls of the tapered slot 332 to form the resilient membrane 333. After the tapered protrusion 342 of the bottom block 34 abuts against the tapered groove 332 of the top block 33, the elastic membrane 333 abuts against the small steel ball 3422.

Referring to fig. 4 and 5, the vertical section of the latch 341 is L, and is divided into a vertical segment 3411 vertically defined on the bottom block 34 and a horizontal segment 3412 vertically fixed to the top end of the vertical segment 3411.

A limit block 3311 is arranged in the clamping groove 331, and the length and the width of the limit block 3311 are both smaller than those of the clamping groove 331. The stopper 3311 divides the slot into three parts, namely a notch 3312 into which the horizontal section 3412 is inserted, a first slide groove 3313 through which the vertical section 3411 slides, and a second slide groove 3314 through which the horizontal section 3412 slides.

During installation, the horizontal section 3412 of the fixture block 341 is inserted into the clamping groove 331 from the notch 3312, the horizontal section 3412 is aligned with the second sliding groove, the vertical section 3411 is aligned with the first sliding groove 3313, then the top block 33 or the bottom block 34 is rotated to drive the fixture block 341 to slide in the clamping groove 331, and when the fixture block 341 slides to the end far away from the notch 3312, the limiting block 3311 limits the horizontal section 3412 and prevents the fixture block 341 from being pulled out of the clamping groove 331.

Referring to fig. 6, the screw stub 4 includes a rod body 41 slidably coupled with the connection block 3 and a mounting block 42 fixed to the rod body 41. The rod 41 is provided with a thread (not shown) so that the rod 41 can be screwed with the mating block 121. One end of the rod body 41 far away from the mounting block 42 is provided with a conical surface 412; the rod body 41 is provided with an annular matching groove 411, and when the bottom end of the mounting block 42 is abutted to the matching block 121, the small steel ball 3422 is arranged in the matching groove 411. One end of the mounting block 42 away from the rod 41 is provided with a cross-shaped mounting groove 421.

Referring to fig. 7 and 8, the temple 12 is divided into a rotating portion 123 and an extended portion 122. An accommodating cavity 1231 is formed in one end, close to the extending portion 122, of the rotating portion 123, a connecting rod 1221 capable of penetrating into the extending portion 122 is fixed at one end, close to the rotating portion 123, of the extending portion 122, and the connecting rod 1221 is in threaded connection with the accommodating cavity 1231, so that connection between the rotating portion 123 and the extending portion 122 is achieved. The depth of the accommodating chamber 1231 is greater than the length of the connecting rod 1221, so that after the rotating part 123 and the extending part 122 are connected, there is still an extra space in the accommodating chamber 1231 for the spare screw post 4 to be placed. One end of the connecting rod 1221 near the rotating part 123 is provided with a mounting head 1222 in the shape of a cross. The mounting head 1222 is matched with the mounting groove 421 to facilitate the mounting of the spiral stub 4.

The installation mode is as follows: the small steel ball 3422 is firstly arranged in the mounting hole 3421, the clamping block 341 is inserted into the clamping groove 331, and the bottom block 34 is rotated, so that the top block 33 and the bottom block 34 are mounted. And then fixedly connecting the connecting block 3 with the connecting frame 11 (directly performing injection molding on an injection molding machine). After the connecting block 3 is mounted on the connecting frame 11, the connecting portion 31 of the connecting block 3 is placed between the two mating blocks 121 and the screw stubs 4 are inserted vertically.

During the insertion of the screw post 4, the screw post 4 will drive the small steel ball 3422 to move toward the elastic membrane 333 and compress the elastic membrane 333 until the screw post 4 is fully inserted. At this time, the small steel ball 3422 is placed in the fitting groove 411, and under the elastic force of the elastic membrane 333, the small steel ball 3422 is tightly abutted against the fitting groove 411, so that the friction force of the rotation of the spiral stub 4 is increased, and the situation that the spiral stub 4 is separated is reduced.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
