Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology, specifically relating to a connection structure for detachable eyeglass temples. Background Technology

[0002] Eyeglasses, as a common vision correction and eye protection tool, are widely used in daily life and professional fields. Their basic structure typically includes three parts: the frame, lenses, and temples. The temples, as a crucial component supporting the entire pair of glasses and ensuring stable wear on the head, directly affect the comfort, ease of use, and overall aesthetics of the glasses. Currently, most eyeglasses on the market use a traditional structure where the temples are hinged to the frame using screws. This connection method has advantages such as simple structure, low manufacturing cost, and stable connection, and has therefore been widely adopted for a long time.

[0003] Traditional temple connection methods are complicated to replace or repair. Since the temples are usually fixed to the frame with one or two small screws, users often need to use special screwdrivers and other tools to disassemble and install them when replacing the temples. For ordinary consumers, this process is not only cumbersome, but also requires a certain level of technical skill. This is especially inconvenient for children, the elderly, or users with poor vision. In addition, during disassembly, the small screws are very easy to slip off or be lost, making it impossible to replace the temples or rendering the glasses unusable. Utility Model Content

[0004] The purpose of this invention is to provide a detachable eyeglass temple connection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A connecting structure for detachable eyeglass temples includes:

[0007] The frame has temples movably connected to both sides.

[0008] A connecting mechanism is disposed between the frame and the temple. The connecting mechanism includes a support plate fixedly connected to the frame. A hinge is fixedly connected to one side of the support plate. A connecting block is hinged to one side of the hinge. A screw is provided between the connecting block and the hinge. A plug is fixedly installed on the side of the connecting block away from the hinge. A slot is opened on the side of the temple near the frame. The plug is inserted into the slot and slides against the inner wall of the slot. Two positioning grooves are symmetrically opened inside the slot. Two spring pieces are fixedly installed at the end of the plug and are embedded in the positioning grooves.

[0009] Preferably, the hinge and the connecting block are rotatably connected to drive the temple to open and close.

[0010] Preferably, the spring sheet has a U-shaped cross-section, and both the spring sheet and the positioning groove are provided with arc surfaces.

[0011] Preferably, the length of the insertion rod is adapted to that of the slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model adopts a connection method of plug and slot cooperation, supplemented by the snap-fit ​​structure of spring and positioning groove, which replaces the traditional connection method that relies on screws for fixing. When changing the temples, the user does not need to use any tools. Just align the plug with the slot and gently insert it to complete the installation. When disassembling, just apply a certain pulling force to pull out the plug. This plug-and-play design greatly facilitates the user and is especially suitable for occasions where the temples need to be changed frequently, such as matching different clothes, adapting to different occasions, or needing to be temporarily replaced due to temple damage.

[0014] (2) This utility model ensures that the insertion rod can be firmly fixed after being inserted into the slot through the snap-fit ​​design of the spring and the positioning groove, and will not loosen due to daily wear or slight impact. The elastic deformation characteristics of the spring allow the connection structure to maintain a good connection state when subjected to external force. At the same time, it can be easily separated by applying a certain pulling force during disassembly, achieving a good balance between connection stability and disassembly convenience. Both the spring and the positioning groove are designed as arc surface structures. This design not only helps to reduce frictional resistance during insertion and removal and improve the smoothness of operation, but also forms a certain locking effect after the insertion rod is inserted, further enhancing the stability of the connection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1 - Figure 5 As shown, a connecting structure for detachable eyeglass temples includes:

[0025] The frame 1 has temples 2 that are movably connected to both sides of the frame 1.

[0026] The connecting mechanism 3 is located between the frame 1 and the temple 2. The connecting mechanism 3 includes a support plate 31 fixedly connected to the frame 1. A hinge 32 is fixedly connected to one side of the support plate 31. A connecting block 33 is hinged to one side of the hinge 32. A screw 34 is provided between the connecting block 33 and the hinge 32. A plug rod 35 is fixedly installed on the side of the connecting block 33 away from the hinge 32. A slot 36 is opened on the side of the temple 2 near the frame 1. The plug rod 35 is inserted into the slot 36 and slides against the inner wall of the slot 36. Two positioning grooves 37 are symmetrically opened inside the slot 36. Two spring pieces 38 are fixedly installed at the end of the plug rod 35 and are embedded in the positioning grooves 37.

[0027] Specifically, the hinge 32 and the connecting block 33 are rotatably connected to drive the temple 2 to open and close. The spring 38 has a U-shaped cross-section. Both the spring 38 and the positioning groove 37 are provided with arc surfaces. The insertion rod 35 and the slot 36 are matched in length.

[0028] As can be seen from the above, the support plate 31, as the basic component of the connecting mechanism 3, mainly plays a role in bearing and fixing. It firmly connects the hinge 32 to the frame 1, ensuring the stability and reliability of the entire connecting structure. The hinge 32 realizes the opening and closing function between the temple 2 and the frame 1. Through the hinge cooperation with the connecting block 33, the temple 2 can be flexibly opened or closed to adapt to different wearing needs. The connecting block 33, as the mounting base of the insert rod 35, is connected to the hinge 32 by screws 34, which not only ensures the stability of the structure, but also allows for angle adjustment or replacement when necessary. The insert rod 35 and the slot 36 constitute the connection between the temple 2 and the frame 1. The core structure for quick assembly and disassembly uses a rod 35 inserted into a slot 36 to install the temple 2, and removing the rod 35 allows for disassembly of the temple 2. The engaging design between the spring piece 38 and the positioning groove 37 is key to the stable connection of the temple 2. When the rod 35 is inserted into the slot 36, the spring piece 38 deforms under force and slides into the positioning groove 37, forming a firm connection. When disassembly is required, only a certain pulling force needs to be applied to make the spring piece 38 disengage from the positioning groove 37, achieving quick separation of the temple 2. The contact surfaces of the spring piece 38 and the positioning groove 37 are both designed with arc surfaces, which effectively reduces the frictional resistance during insertion and removal, making the connection and disassembly operations smoother.

[0029] In use, the user aligns the end of the temple 2 closest to the frame 1 with the slot 36 and inserts the rod 35 into the slot 36. During insertion, the spring 38 is compressed by the inner wall of the slot 36 and undergoes elastic deformation, gradually contracting inward. When the rod 35 is fully inserted, the spring 38 returns to its original shape, and its end is locked into the positioning groove 37, forming a stable connection. At this time, the spring 38 and the positioning groove 37 are tightly fitted to prevent the rod 35 from accidentally falling off during wear, ensuring the stability and safety of wearing the glasses. When the user needs to replace or remove the temple 2, simply apply a certain pulling force to pull the rod 35 out of the slot 36. Under the action of the pulling force, the spring 38 undergoes elastic deformation again, disengaging from the positioning groove 37, and the rod 35 can be easily pulled out, completing the removal of the temple 2.

[0030] Example 2:

[0031] Please see Figure 6As shown, this embodiment provides an improved connection structure based on embodiment one. Its overall structure and function are basically the same as embodiment one, except that a metal connector is added between the support plate 31 and the hinge 32. The metal connector has a U-shaped structure and is used to connect the two, meeting the diverse needs of different manufacturers in terms of production process, material selection and assembly method. As a transition component between the support plate 31 and the hinge 32, the metal connector makes the connection method more flexible. For example, different manufacturers can choose welding, riveting, screwing or snap-fitting to connect the metal connector to the support plate 31 and the hinge 32 respectively according to their own production process, thereby improving the adaptability and versatility of the product.
