Description

Technical Field

[0001] The utility model relates to the field of glasses, in particular to a special-shaped temple. Background Art

[0002] In the traditional temple ferrule assembly, the conventional ferrule is a straight rod-shaped structure, which is directly driven into the temple shell after injection molding; however, for the arrangement of special-shaped temples and special-shaped ferrules, the ferrules cannot be matched with the temple shell through a single direction of insertion due to the different cross-sections of the ferrules at different length positions, and it is necessary to adopt the method of sheet splicing or casting. The sheet splicing is to design two layers of sheet materials, sandwich the ferrule between them, and then splice the two layers of sheet materials, but this method is prone to defects such as poor sheet bonding, bubbles, easy deformation and shrinkage; and the casting method requires the insertion of the pin after pouring the epoxy resin and other materials on the back, and then pouring the epoxy resin on the front. During processing, complex tooling is required to control the accurate arrangement of the ferrule, and it will turn yellow and break easily after long-term use. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a special-shaped mirror leg which is convenient for arranging the special-shaped insert and has a good molding effect.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a special-shaped temple, including a plate layer, a core and a casting layer, the plate layer is provided with a matching installation groove corresponding to the shape of the core, and the core is arranged in the installation groove of the plate layer; a casting layer is provided above the core and the plate layer.

[0005] Furthermore, the casting layer and the plate layer are hierarchical structures with compatibility.

[0006] Furthermore, the board layer is an acetate fiber layer.

[0007] Furthermore, the casting layer is a transparent layer.

[0008] Furthermore, the casting layer is an epoxy resin layer.

[0009] Furthermore, the casting layer is a propionate fiber layer.

[0010] The beneficial effects of the utility model are as follows: through the design of the mounting groove of the plate layer, various types of inserts can be placed in the corresponding mounting grooves to meet the design of special-shaped temples and inserts; the inserts are fixed by pouring and solidifying the casting layer on the plate layer; this type of temple can avoid the problems of poor molding caused by traditional plate splicing or full casting for special-shaped temples, layered seams and the need for complex tooling design.

[0015] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0016] Please refer to Figure 1 to Figure 2 A special-shaped temple comprises a plate layer, an insert and a casting layer, wherein the plate layer is provided with a matching mounting groove corresponding to the shape of the insert, and the insert is arranged on the plate layer; a casting layer is arranged above the insert and the plate layer.

[0017] From the above description, it can be seen that the beneficial effects of the utility model are: through the design of the installation groove of the plate layer, various types of ferrules can be placed in the corresponding installation groove, which plays a role in the rapid limiting assembly of the ferrule and meets the design of special-shaped temples and ferrules; the ferrule is fixed by pouring and solidifying the casting layer on the plate layer; this type of temple can avoid the poor molding caused by the traditional plate splicing or full casting form for special-shaped temples, with layered seams and the need for complex tooling design.

[0018] Furthermore, the casting layer and the plate layer are hierarchical structures with compatibility.

[0019] From the above description, it can be seen that by adopting a miscible hierarchical structure, after the casting layer is cast, the solidified hierarchical structure can be seamlessly connected to the plate layer, so that no seams are produced on the surface, thereby ensuring that no deformation and delamination will occur when the temples are bent in use.

[0020] Furthermore, the board layer is an acetate fiber layer.

[0021] From the above description, it can be seen that the design using the acetate fiber layer has a light and comfortable use effect, and at the same time has reliable durability; it is easy to dye and can present rich colors to meet the diverse needs of users.

[0022] Furthermore, the casting layer is a transparent layer.

[0023] From the above description, it can be seen that the color of the board layer can be intuitively presented through the design of the transparent casting layer. At the same time, compared with the casting layer, the color design of the board layer itself can be richer. The color is presented through the board layer, and the performance effect of the product design is better. In addition, the design of the transparent layer can also make the shape design on the plug intuitively displayed. The transparent layer can present a rich design of the plug and the shape and color of the temple.

[0024] Furthermore, the casting layer is an epoxy resin layer.

[0025] From the above description, it can be seen that epoxy resin, as a common casting material, is partially miscible with acetate fiber and can be directly used for casting acetate fiber sheets. It can not only meet the needs of fixing the inserts of special-shaped temples but also accurately present the color of the sheet layer through its transparent characteristics.

[0026] Furthermore, the casting layer is a propionate fiber layer.

[0027] From the above description, it can be seen that when propionate fiber is used as a casting material, it has good compatibility with acetate fiber, which can ensure reliable bonding between the board layer and the casting layer, and it is transparent itself, which can accurately present the color of the board layer; at the same time, it can avoid the yellowing and easy breakage caused by long-term use of traditional epoxy resin casting.

[0028] Embodiment 1:

[0029] Application scenario: For the structural design of temples with special-shaped inserts, traditional sheet material splicing and casting methods have certain molding defects and inconvenience in operation.

[0030] like Figure 1 and Figure 2 As shown, the special-shaped temple of this embodiment includes a plate layer, a core and a casting layer, the plate layer is provided with a matching mounting groove corresponding to the shape of the core, and the core is arranged in the mounting groove of the plate layer; a casting layer is provided above the core and the plate layer.

[0031] The casting layer and the plate layer are in a hierarchical structure with compatibility.

[0032] In this embodiment, the board layer is an acetate fiber layer, and the casting layer is an epoxy resin layer. The casting layer is a transparent layer, which can well present the rich colors of the board layer.

[0033] Embodiment 2:

[0034] The difference between the second embodiment and the first embodiment is that the casting layer is a propionate fiber layer. During processing, a propionate fiber solution is used to cast on the acetate fiber layer where the special-shaped plug is placed. Compared with the traditional epoxy resin, it has the transparent property of accurately presenting the color of the board layer and can avoid the phenomenon of discoloration and yellowing and easy breakage caused by long-term use of epoxy resin.

[0035] In summary, the utility model provides a special-shaped temple, which, through the design of the mounting groove of the plate layer, allows various types of inserts to be placed in the corresponding mounting groove, thereby meeting the design of the special-shaped temple and the insert; the insert is fixed by pouring and solidifying the casting layer on the plate layer; this type of temple can avoid the problems of poor molding caused by traditional plate splicing or full casting for special-shaped temples, layered seams, and the need for complex tooling design.
