Description

TECHNICAL FIELD

[0001] The utility model relates to the field of glasses, specifically to a connecting structure for glasses and glasses. BACKGROUND

[0002] Glasses are a kind of products with wide application in wearable products, mainly including a frame, a lens and a temple, and a nose pad is arranged on the frame. Some glasses in the prior art adopt a split frame in which the lens is clamped by the upper frame and the lower frame, and the upper frame and the lower frame are not easy to be separated after being fixed at both ends. However, if the position corresponding to the nose bridge of the wearer is not fixed well, the upper frame and the lower frame may be separated after long-term use. In addition, the nose pad integrated with the frame has poor flexibility and flexibility, and the wearing comfort is low. Therefore, more glasses choose to install an independent nose pad, and how to install the nose pad for the split frame is a problem to be considered. SUMMARY

[0003] In view of the deficiencies of the prior art, the utility model provides a connecting structure for glasses, which ingeniously utilizes a nose pad assembly to realize the connection of the upper frame and the lower frame, and facilitates the replacement of the nose pad assembly.

[0024] like Figures 1 to 7 As shown, this embodiment discloses a pair of glasses, including an upper frame 1, a lower frame 6, an elastic positioning member, and a nose pad assembly. The bottom surface of the upper frame 1 is provided with a positioning groove 13 (e.g., ...). Figure 5 The lower frame 6 partially protrudes upward to form a raised portion 18, and the inner side of the upper frame 1 is provided with a first slot 16, and the raised portion 18 is provided with a second slot 19 (e.g. Figure 7 The protrusion 18 is inserted into the positioning groove to achieve mutual positioning of the upper frame and the lower frame. At the same time, the second slot 19 is connected to the first slot 16. An elastic positioning member is installed inside the upper frame 1. The elastic positioning member has a retractable lower end, and the lower end of the elastic positioning member extends into the first slot 16.

[0025] The nose pad assembly includes a nose pad bracket and two nose pads 3 connected to the nose pad bracket 2. The upper end of the nose pad bracket 2 has a plug-in part 7 that can be inserted into the first slot 16. The plug-in part 7 is provided with a positioning hole 8.

[0026] When the plug part 7 is inserted into the first slot 16 and the second slot 19, the lower end of the elastic positioning member is automatically inserted into the positioning hole 8; when the nose pad assembly is subjected to an external force that causes it to disengage from the first slot 16 and the second slot 19, the elastic positioning member automatically disengages from the positioning hole 8 through elastic deformation.

[0027] The elastic positioning element can be a one-piece molded metal spring, such as a V-shaped metal sheet with a positioning bead (often installed inside a tube to achieve relative expansion and contraction of two tubes, such as the handle of a folding umbrella), or it can be a composite structure, such as a spring with one end connected to a positioning block, which can be inserted into or detached from the positioning hole 8. In this embodiment, the elastic positioning element is preferably a spring positioning bead 4. The spring positioning bead 4 is existing technology and can be purchased from the market in suitable specifications at a low price. The structure of the spring positioning bead 4 typically includes a shell with one open end, a spring and a ball disposed inside the shell, with the ball partially exposed at the open end of the shell (the diameter of the open end is smaller than the diameter of the ball to prevent the ball from falling out of the shell), one end of the spring abutting against the ball, and the other end abutting against the inner wall of the shell.

[0028] In this embodiment, a spring positioning bead 4 is vertically arranged above the first slot 16, and a vertical positioning hole 8 is provided on the insertion part 7 of the nose pad bracket 2. The insertion part 7 is horizontally inserted into the first slot 1611, and the ball bearing of the spring positioning bead 4 will enter the vertical positioning hole 8 to prevent the nose pad assembly from automatically falling off the upper frame 1 without external force. When the nose pad assembly is pulled out of the first slot 1611 horizontally, the spring positioning bead 4 will automatically disengage from the vertical positioning hole 8, thereby allowing the nose pad assembly to be removed from the upper frame 1. The installation and removal of the nose pad assembly is very convenient, quick, easy, and requires no tools. In other embodiments, the spring positioning bead 4 can be embedded below the first slot 16, or spring positioning beads 4 can be provided both above and below the first slot 16. The number of spring positioning beads 4 provided above or below the first slot 16 is not limited, and the positioning hole 8 corresponds one-to-one with the spring positioning bead 4.

[0029] Preferably, the inner side of the upper frame 1 protrudes above and below the opening of the first slot 16 to form an upper protrusion 11 and a lower protrusion 12, respectively. The lower bottom surface of the upper protrusion 11 is flush with the top surface of the first slot 16, and the top surface of the lower protrusion 12 is flush with the bottom surface of the first slot 16. By setting the upper protrusion 11 and the lower protrusion 12, it is not necessary to increase the overall thickness of the upper frame 1. The upper protrusion 11 and the lower protrusion 12 can support the insertion part 7 of the nose pad support 2, making the nose pad assembly more stable.

[0030] The positioning groove of the upper frame 1 extends downward in a portion to form a column. The column has a clamping hole 14 for installing a spring positioning bead. A slit 15 is provided on the side wall of the clamping hole 14. The spring positioning bead 4 is interference-fitted with the clamping hole 14. The protrusion 18 of the lower frame has a clearance notch 20 to avoid the column. The clearance notch 20 connects to the second slot 19. The slit 15 gives the clamping hole 14 a certain elastic deformation capability, which facilitates the insertion of the spring positioning bead 4 into the clamping hole 14, and also gives the wall of the clamping hole 14 a certain clamping force on the spring positioning bead 4.

[0031] In this embodiment, the nose pad 3 and the nose pad support 2 are detachably plugged in. Specifically, the lower end of the nose pad support 2 is provided with a mounting hole 9, and the inner wall of the mounting hole 9 is provided with two opposing protrusions 10. The nose pad 3 includes a first part 31 for connecting with the nose pad support 2 and a second part 32 fixed on the first part 31 for contacting the wearer's nose bridge. The surface of the first part 31 of the nose pad 3 is provided with two opposing grooves 33. The first part 31 of the nose pad 3 is inserted into the mounting hole 9 of the nose pad support 2. The two protrusions 10 cooperate with the two grooves 33 respectively to fix the nose pad 3. The protrusions 10 have room to move in the grooves 33, and the nose pad 3 is movable relative to the nose pad support 2. By pulling the nose pad 3, the nose pad 3 can be separated from the nose pad support 2, so that the nose pad 3 can be replaced separately. The nose pad 3 and the nose pad support 2 are plugged in through the cooperation of the protrusions 10 and the grooves 33, which is convenient to assemble and does not require tools. Preferably, the protrusions 10 and the nose pad support 2 are integrally formed.

[0032] In other embodiments, the nose pad 3 and the nose pad support 2 can be connected in other ways. For example, the nose pad 3 and the nose pad support 2 can be connected by screws or integrally formed. In this embodiment, the nose pad support 2 is preferably made of metal, which has a certain degree of elasticity and can better match different nose bridges. The protrusion 10 is formed by stamping. In other embodiments, the nose pad support 2 can also be made of materials such as plastic or composite materials.

[0033] In other embodiments, a double-headed spring positioning bead 4 can be provided on the upper lens frame 1, and two upper and lower first slots 16 can be provided on the upper lens frame 1. The two ends of the spring positioning bead 4 are respectively inserted into the upper and lower first slots 16, and the nose pad support 2 is provided with two horizontal insertion parts 7, which are respectively inserted into the two first slots 16 for fixing the spring positioning bead 4.
