Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a pair of frameless glasses. Background Art

[0002] Rimless glasses are glasses without a frame structure. Their characteristic is that the center bridge and temples are directly connected to the lenses, giving the glasses a simpler appearance and lighter weight. They are especially popular among business people. In the existing technology, the studs are generally fixed to the lenses by screwing screws on the studs or screwing nuts through the lenses. However, this method of connecting the studs and the lenses will cause looseness between the studs and the lenses after the screws become loose, and then cause looseness between the temples and the lenses, affecting the wearing experience of the glasses.

[0003] In view of the above problems, the present invention makes improvements. Utility Model Content

DETAILED DESCRIPTION

[0021] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] As shown in the figure, a pair of frameless glasses includes a lens 1, a stud 2, a temple 3 and a center bridge 4, the temple 3 is rotatably connected to the stud 2, a first plug-in stud 21 is formed on the stud 2, a first plug-in hole 11 matching the first plug-in stud 21 is provided on the lens 1, a first arc-shaped screw half-groove 22 is formed on the outer wall of the first plug-in stud 21, a second arc-shaped screw half-groove 12 is formed on the inner wall of the first plug-in hole 11, the first plug-in stud 21 is inserted into the first plug-in hole 11 so that the first screw half-groove 22 and the second screw half-groove 12 are combined to form a first screw hole 5, the first screw half-groove 22 and the second screw half-groove 12 are respectively formed with a first thread and a second thread that are connected to each other on the inner walls, and a first bolt 6 that is screwed into the first screw hole 5 and meshes with the first thread and the second thread at the same time is screwed.

[0023] In the above structure, the arc-shaped first screw connection half groove 22 and the second screw connection half groove 12 are aligned and spliced ​​to form a first screw connection hole 5 that matches the first bolt 6, and the first thread on the inner wall of the first screw connection half groove 22 is aligned and connected with the second thread on the inner wall of the second screw connection half groove 12, so that the first bolt 6 can be screwed into the first screw connection hole 5 and engage with the first thread and the second thread at the same time. The cooperation between the first bolt 6 and the second thread limits the relative displacement of the first bolt 6 and the lens 1 in the axial direction of the first bolt 6, so that the first bolt 6 is kept in the second screw connection half groove 12. The engagement of the first bolt 6 and the second thread limits the relative displacement of the first bolt 6 and the first plug pile 21 in the axial direction of the first bolt 6, so that the first plug pile 21 is kept. The first screw half groove 22 is used to keep the first plug pile 21 in the first plug hole 11. At the same time, the first bolt 6 limits the rotation of the first plug pile 21 in the first plug hole 11, thereby realizing a fixed connection between the pile head 2 and the lens 1. The connection between the pile head 2 and the lens 1 achieved in the above manner, even if the first bolt 6 becomes loose, before the first bolt 6 is completely withdrawn from the first screw hole 5, the first bolt 6 still remains engaged with the first thread and the second thread, which makes the first plug pile 21 still stably maintained in the first plug hole 11, thereby enhancing the stability of the connection between the pile head 2 and the lens 1, and the two are not easy to loosen, thereby enhancing the stability of the connection between the temple 3 and the lens 1, thereby ensuring a good experience when wearing the glasses.

[0024] In addition, based on the above structure, the first bolt 6 is a headless bolt, so that the first bolt 6 can be completely sunk into the first screw hole 5 when screwed into the first screw hole 5, thereby ensuring the overall aesthetics of the glasses and preventing the first bolt 6 from loosening due to external force, thereby ensuring the stability of the connection between the pile head 2 and the lens 1.

[0025] In addition, on the basis of the above structure, a second screw hole 23 connected to the first screw half groove 22 is formed on the pile head 2, and the first thread extends to the inner wall of the second screw hole 23, and the first bolt 6 is screwed into the second screw hole 23. After being screwed into the first screw hole 5, the first spiral continues to rotate forward and screws into the second screw hole 23. The screw connection between the first bolt 6 and the second screw hole 23 strengthens the connection strength between the first bolt 6 and the first plug-in pile 21, so that the first bolt 6 can exert a stronger limiting effect on the first plug-in pile 21, thereby enhancing the stability of the connection between the pile head 2 and the lens 1.

[0026] The temple 3 is fixed with the support 24 on both sides of the hinge 24 so as to be able to move freely.

[0027] In addition, on the basis of the above structure, a second plugging pile 41 is formed at each end of the middle beam 4, and a second plugging hole 13 matching the second plugging pile 41 is provided on the lens 1. A third screw half groove 42 is formed on the outer wall of the second plugging pile 41, and a fourth screw half groove 14 is formed on the inner wall of the second plugging hole 13. The second plugging pile 41 is inserted into the second plugging hole 13 so that the third screw half groove 42 and the fourth screw half groove 14 are combined to form a third screw hole 7, and the inner walls of the third screw half groove 42 and the fourth screw half groove 14 are formed with a third screw half groove 14 that is connected to each other. Three threads and a fourth thread, a second bolt 8 that is simultaneously engaged with the third thread and the fourth thread is screwed into the third screw hole 7, two fourth screw holes 43 that are respectively connected to the two third screw half grooves 42 are formed on the center beam 4, the third thread extends to the inner wall of the fourth screw hole 43, and the second bolt 8 is screwed into the fourth screw hole 43. In the above structure, the center beam 4 is connected to the lens 1 in the same manner as the connection structure between the above-mentioned pile head 2 and the lens 1, thereby enhancing the stability of the connection between the center beam 4 and the lens 1 and ensuring a good experience when wearing the glasses.

[0028] In addition, on the basis of the above structure, a decorative piece 9 is provided in the middle of the center beam 4. The cross-section of the decorative piece 9 is U-shaped and a vertical portion of the decorative piece 9 is bent inward to form a limiting portion 91. A snap-in groove 44 matching the decorative piece 9 is formed on the center beam 4. The decorative piece 9 is inserted into the snap-in groove 44 so that the limiting portion 91 is clamped on the center beam 4. After the limiting portion 91 is clamped on the center beam 4, the displacement of the decorative piece 9 relative to the center beam 4 is limited so that the decorative piece 9 remains in the snap-in groove 44, thereby realizing a detachable connection between the decorative piece 9 and the center beam 4. The decorative piece 9 plays a decorative role on the center beam 4, making the glasses more beautiful as a whole, and the decorative piece 9 with different colors and shapes can be replaced according to the needs of the wearer to meet the different aesthetic needs of the wearer.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
