[0004] The lens 1 is provided with a fixing hole 11 and a positioning hole 12. The pile head 2 is provided with a fixing post 21 and a positioning post 22 that are respectively connected to the fixing hole 11 and the positioning hole 12.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A frameless eyeglasses design that is easy to assemble and disassemble includes a lens and a post. The lens has a fixing hole and a positioning hole. The post has a fixing post and a positioning post that are respectively inserted into the fixing hole and the positioning hole. The lens also has an assembly hole. The centers of the assembly hole, the fixing hole, and the positioning hole are located on the same straight line.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] For reference as follows Figures 1-3 The present invention will be described as follows:

[0028] Example: A frameless eyeglasses that is easy to assemble and disassemble includes a lens 1 and a post 2. The lens 1 is provided with a fixing hole 11 and a positioning hole 12. The post 2 is provided with a fixing post 21 and a positioning post 22 that are respectively inserted into the fixing hole 11 and the positioning hole 12.

[0029] The above is the prior art; the following is the improved technology of this application:

[0030] The lens 1 is also provided with an assembly hole 3. The centers of the assembly hole 3, the fixing hole 11, and the positioning hole 12 are located on the same straight line. The fixing hole 11 is located between the assembly hole 3 and the positioning hole 12, and the positioning hole 12 is located near the edge of the lens 1. The fixing hole 11 and the positioning hole 12 have the same diameter, and the diameter of the assembly hole 3 is larger than the diameter of the fixing hole 11.

[0031] Lens 1 has three key holes: mounting hole 3, fixing hole 11, and positioning hole 12. The centers of these three holes are on the same straight line, forming a precise assembly axis. Fixing hole 11 is located between mounting hole 3 and positioning hole 12, while positioning hole 12 is positioned close to the edge of lens 1. This layout provides reasonable space planning for subsequent pile head installation. The diameter of mounting hole 3 is larger than that of fixing hole 11, while fixing hole 11 and positioning hole 12 have the same diameter. This dimensional setting is to accommodate the installation requirements of different components.

[0032] The diameter of the fixing post 21 is equal to the diameter of the fixing hole 11, and the diameter of the positioning post 22 is equal to the diameter of the positioning hole 12. This ensures precise fit during insertion.

[0033] It also includes a connecting groove 4 that connects the assembly hole 3, the fixing hole 11, and the positioning hole 12. The connecting groove 4 is located on a straight line where the centers of the assembly hole 3, the fixing hole 11, and the positioning hole 12 are located. The width of the connecting groove 4 is smaller than the diameter of the fixing post 21. This design is an important part of fixing the post head to the lens.

[0034] A locking disc 5 is coaxially mounted at the end of the fixing post 21. The diameter of the locking disc 5 is larger than the diameter of the fixing hole 11, and the diameter of the locking disc 5 is smaller than or equal to the diameter of the assembly hole 3. This design enables the locking disc 5 to play a crucial locking role during assembly.

[0035] The distance from the center of the fixing hole 11 to the center of the positioning hole 12 is equal to the distance from the center of the fixing hole 11 to the center of the assembly hole 3; this precise dimensional correspondence ensures that each component can be accurately aligned during pile head installation.

[0036] The distance from the center of the fixing hole 11 to the center of the positioning hole 12 is equal to the distance from the center of the fixing post 21 to the center of the positioning post 22.

[0037] The length of the fixing post 21 is less than the thickness of the lens 1 around the fixing hole 11. This allows the locking disc 5 and the pin 2 to clamp and fix the lens 1, ensuring the stability of the connection. The thickness of the lens 1 around the fixing hole 11 is 3mm, and the length of the fixing post 21 is 2.5mm. The edge of the locking disc 5 can be chamfered to prevent the edge of the locking disc 5 from colliding with the lens 1, which would make it difficult to pull the pin 2.

[0038] During assembly, the locking disc 5 and the fixing post 21 are first inserted into the assembly hole 3. Since the diameter of the assembly hole 3 is greater than or equal to the diameter of the locking disc 5, they can be inserted smoothly. At the same time, the positioning post 22 is inserted into the fixing hole 11, at which point the positioning post 22 and the fixing hole 11 are precisely matched.

[0039] After insertion, pull the pile head 2 outward. During the pulling process, the fixing column 21 and the positioning column 22 will move along the connecting groove 4. Since the width of the connecting groove 4 is smaller than the diameter of the fixing column 21, the fixing column 21 and the positioning column 22 will force the connecting groove 4 to undergo elastic expansion deformation. When it moves to the position of the fixing hole 11 and the positioning hole 12, the deformation of the connecting groove 4 returns to normal, the fixing column 21 enters the fixing hole 11, and the positioning column 22 enters the positioning hole 12.

[0040] At this time, the fixing post 21 engages with the fixing hole 11, and the positioning post 22 engages with the positioning hole 12, fixing the pile head 2 and the lens 1 in the circumferential and radial directions of the fixing post 21. Simultaneously, because the diameter of the locking disc 5 is larger than the diameter of the fixing hole 11, the locking disc 5 cannot pass through the fixing hole 11, thus limiting the pile head 2 in the axial direction of the fixing post 21, thereby axially fixing the pile head 2 and the lens 1.

[0041] The fixing post 21 and the positioning post 22, working in the fixing hole 11 and the positioning hole 12, fix the pile head in the circumferential and radial directions, preventing it from rotating or moving left or right. The locking disc 5, on the other hand, fixes the pile head in the axial direction, preventing it from falling off. This multi-directional fixing mechanism ensures the strength of the connection.

[0042] Compared with existing technologies, this invention eliminates the need for complex operations such as tightening nuts during assembly; a simple pull on the pile head 2 is all that is required, greatly simplifying the assembly process. This design makes the assembly process more convenient and efficient, significantly improving production efficiency and reducing assembly costs.

[0043] The precise dimensional fit and rational layout design between the various components ensure the stability of the glasses during use. Even under external force, the connection between the pin and the lens remains firm and does not easily loosen, thus guaranteeing the normal use of the glasses.

[0044] The pile head 2 has an L-shaped structure and includes a fixed arm 23 and a connecting arm 24 (the fixed arm 23 is used to connect with the lens 1, and the connecting arm 24 is used to connect with the temple of the eyeglasses). The fixed post 21 and the positioning post 22 are set on the fixed arm 23.

[0045] The distance from the center of the fixing post 21 to the connecting arm 24 is greater than the distance from the center of the mounting hole 3 to the edge of the lens 1. During assembly, this dimensional relationship ensures that the connecting arm 24 will not collide or interfere with the lens 1 when the fixing post 21 enters the mounting hole 3.

[0046] The end of the fixing arm 23 is provided with a shielding part 25. After the pile head 2 and the lens 1 are fixed, the shielding part 25 is used to shield the mounting hole 3.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
