Technical Field
[0001] This utility model relates to the field of eyeglasses technology, specifically to a lens and eyeglasses with a positioning slot on the side. Background Technology
[0002] In the eyewear manufacturing industry, rimless glasses are highly favored by consumers due to their simple and stylish design.
[0003] A utility model patent with patent authorization announcement number CN2537025Y discloses a typical frameless eyeglasses structure. In this structure, the lens has two connecting holes, and correspondingly, the temples have two connecting posts. During assembly, the lens and temples are fixedly connected by precisely inserting the connecting posts on the temples into the connecting holes of the lens.
[0004] In the above structure, the positions of the connecting post and the connecting hole must be precisely positioned, otherwise it will be difficult to align and insert them. This places high demands on the machining of the connecting hole and the manufacturing precision of the connecting post, increasing the manufacturing difficulty. Utility Model Content
[0005] In view of the problems pointed out in the background art, the present invention proposes a lens and eyeglasses with positioning slots on the side to solve the above-mentioned technical problems.
[0006] The technical solution of this utility model is implemented as follows:
[0007] A lens with positioning slots on its side includes a spectacle lens body, wherein the spectacle lens body has connecting holes extending through both sides of its thickness direction, and the spectacle lens body has connecting slots extending through both sides of its thickness direction, the connecting slots being disposed through the edge of the spectacle lens body.
[0008] The present invention is further configured such that the connecting groove on the lens body is arranged in the left-right direction, and the connecting hole is located inside the connecting groove and the two are spaced apart.
[0009] A pair of eyeglasses includes temples and the aforementioned lenses. The temples include an elongated temple body, with a first clamping portion perpendicular to the front end of the temple body. The first clamping portion has a positioning portion that can be inserted into a connecting groove. The first clamping portion has a threaded hole corresponding to the connecting hole, and also includes a fastening screw connected to the connecting hole and the threaded hole.
[0010] The present invention is further configured to include a second clamping part perpendicular to the temple body, and a positioning part located between the first clamping part and the second clamping part.
[0011] The present invention is further configured such that the length of the second clamping part is less than the length of the first clamping part, and the end of the second clamping part forms an arc-shaped groove, the groove being coaxially arranged with the threaded hole, and the diameter of the groove being equal to the diameter of the screw head.
[0012] The present invention is further configured such that the distance between the first clamping part and the second clamping part is equal to the thickness of the lens body.
[0013] The present invention is further configured such that, in the left-right direction, the positioning part is spaced apart from the bottom of the connecting groove.
[0014] The present invention is further configured such that the positioning part is fixedly connected to the first clamping part, the temple body, and the second clamping part.
[0015] The present invention is further configured such that the threaded hole is provided only through the first clamping part on the side facing the lens body.
[0016] The present invention is further configured such that the width of the first clamping part and the second clamping part is greater than the width of the positioning part.
[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0018] The lens and eyeglasses provided by this utility model have positioning slots on their sides. When the lens body is connected to the temple, the connecting slot on the lens body aligns with the positioning part on the first clamping part, and the threaded hole on the first clamping part corresponds to the connecting hole on the lens body. At this time, the first clamping part is located on the front side of the lens body. The fastening screw is inserted into the connecting hole and the threaded hole from the rear side of the lens body. After tightening the fastening screw, the fastening screw and the threaded hole on the first clamping part are tightly engaged to form a fixed connection. The engagement between the positioning part and the connecting slot can prevent the temple from rotating around the fastening screw. This combination of the fastening screw and the positioning part forms a fixed connection between the temple and the lens body.
[0019] During assembly, after the positioning part is inserted into the connecting groove, the position of the first clamping part is adjusted so that the threaded hole aligns with the connecting hole. Compared with existing technologies, this eliminates the need to consider the alignment of the two holes, reducing manufacturing precision requirements and manufacturing difficulty.

[0029] 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.
[0030] For reference as follows Figures 1-7 The present invention will be described as follows:
[0031] Example: A lens with positioning slots on the side includes a lens body 1, a lens body 1 with connecting holes 2 penetrating both sides of its thickness direction, and a connecting groove 3 penetrating both sides of its thickness direction, the connecting groove 3 penetrating the edge of the lens body 1.
[0032] In terms of position, the connecting groove 3 is distributed along the left and right direction, while the connecting hole 2 is located inside the connecting groove 3, and the two are set at intervals.
[0033] In this structural design, the connecting hole 2 serves as a traditional fastening connection point, providing a basic connection channel for fixing the lens to the temple; while the connecting groove 3, which runs through the edge of the lens, breaks away from the traditional mode of relying solely on hole-like structures for connection and positioning. Its orientation along the left and right directions is adapted to the overall shape of the lens, providing a clear insertion guide for the positioning components of the temple during assembly.
[0034] An eyeglass, comprising temples and the aforementioned lenses.
[0035] The temple of the eyeglasses includes a long, narrow temple body 5. The front end of the temple body 5 has a first clamping part 6 perpendicular to it. The first clamping part 6 has a positioning part 7 that can be inserted into a connecting groove 3. The first clamping part 6 has a threaded hole 8 corresponding to the connecting hole 2. It also includes a fastening screw 9 that connects to the connecting hole 2 and the threaded hole 8. The lens is fixed to the temple by the fastening screw 9 passing through the connecting hole 2 and connecting to the threaded hole 8.
[0036] During the connection process, the perpendicular relationship between the first clamping part 6 and the temple body 5 ensures that the clamping part can fit against the lens at a suitable angle, so that the positioning part 7 and the threaded hole 8 can accurately correspond to the connecting groove 3 and the connecting hole 2 on the lens. After the positioning part 7 is inserted into the connecting groove 3, a preliminary positioning fit is formed. At this time, the fastening screw 9 passes through the connecting hole 2 from the back side of the lens and is tightened into the threaded hole 8. Through the mechanical engagement of the screw and the thread, the lens is tightly fixed to the first clamping part 6, thereby achieving a stable connection between the lens and the temple.
[0037] The precise positioning of the structure is achieved through the cooperation between the positioning part 7 and the connecting groove 3. When the positioning part 7 is inserted into the connecting groove 3, the groove wall of the connecting groove 3 constrains the positioning part 7, effectively preventing the temple from rotating around the fastening screw 9. This constraint effect stems from the shape matching between the groove and the positioning part. After assembly, even under external force, the positioning part is unlikely to undergo circumferential displacement within the connecting groove, thus ensuring the stability of the relative position between the temple and the lens.
[0038] The tightening of the fastening screw 9 into the threaded hole 8 plays the main role in fastening. Through the axial pressure of the screw, the lens is tightly fitted to the first clamping part 6, preventing them from separating in the axial direction. The positioning and fastening functions work together to form a stable fixed connection structure, ensuring the firmness of the connection while avoiding loosening or displacement problems that may occur due to a single connection method.
[0039] Compared with the existing technology that relies on the mating of two connecting holes and connecting posts, this technical solution has significant advantages in manufacturing and assembly.
[0040] In terms of manufacturing, existing technologies require that the positions of the two connecting holes and the two connecting posts must correspond precisely; otherwise, assembly difficulties will occur, placing extremely high demands on the machining accuracy of the holes and posts. In this solution, the cooperation between the connecting groove 3 and the positioning part 7 provides a certain degree of adjustment space for assembly. Even if there is a slight deviation in the position of the connecting hole 2 and the threaded hole 8, after the positioning part 7 is inserted into the connecting groove 3, the position of the first clamping part 6 can still be adjusted to make the threaded hole correspond to the connecting hole. This adjustability reduces the requirements for the machining accuracy of the connecting holes and threaded holes, reduces the product scrap rate caused by machining errors, and thus reduces manufacturing difficulty and production costs.
[0041] In terms of assembly, existing technologies require two connecting posts to be aligned with two connecting holes simultaneously before insertion, necessitating repeated adjustments during assembly, resulting in low efficiency. In this new design, the insertion of the positioning part 7 into the connecting groove 3 provides clear guidance. Assemblers can quickly complete initial positioning through the cooperation between the connecting groove 3 and the positioning part 7, and then fine-tune to align the threaded hole with the connecting hole, greatly simplifying the assembly process and improving assembly efficiency.
[0042] At the same time, this structure also has advantages in later maintenance. When the connection part is damaged and needs repair or replacement, the replacement part is easier to adapt to the original lens or temple because the requirements for manufacturing precision are reduced. This reduces the difficulty of adjustment during the repair process and lowers repair costs and time costs.
[0043] It also includes a second clamping part 10 perpendicular to the temple body 5, and a positioning part 7 located between the first clamping part 6 and the second clamping part 10. The distance between the first clamping part 6 and the second clamping part 10 is equal to the thickness of the lens body 1. With this arrangement, after the lens body 1 is aligned and inserted with the positioning part 7, the lens body 1 is constrained by the first clamping part 6 and the second clamping part 10, thus further enhancing the stability and firmness of the connection between the temple body 5 and the temple.
[0044] The length of the second clamping part 10 is less than the length of the first clamping part 6. This dimensional difference ensures that the second clamping part 10 will not obstruct the connecting hole 2 after assembly.
[0045] The end of the second clamping part 10 forms an arc-shaped groove 11, which is coaxially arranged with the threaded hole 8. The diameter of the groove 11 is equal to the diameter of the screw head of the fastening screw 9. When the fastening screw 9 is tightened, its screw head can completely enter the groove 11 and form a fit. From the perspective of structural stability, this fit relationship allows the screw head to form a tight contact with the second clamping part 10. The screw head is constrained by the groove wall of the groove 11, which can further limit the axial and radial displacement of the fastening screw 9, reduce the possibility of screw loosening, and thus enhance the stability of the overall connection structure.
[0046] From an aesthetic point of view, the screw head is fully embedded in the groove 11, avoiding the abruptness caused by the exposed screw head, making the structural transition of the fastening part smoother and improving the overall visual effect of the glasses.
[0047] In the left-right direction, the positioning part 7 is spaced apart from the bottom of the connecting groove 3. This spacing provides a certain adjustment margin for the assembly process. When the positioning part 7 is inserted into the connecting groove 3, if it is necessary to fine-tune the position of the first clamping part 6 to ensure that the threaded hole 8 and the connecting hole 2 are precisely aligned, this spacing can accommodate the positioning part 7 to move slightly in the left-right direction within the connecting groove 3. This avoids the inability to adjust due to the positioning part being completely fitted to the bottom of the connecting groove, further reducing the dependence on manufacturing precision and improving the flexibility of assembly.
[0048] The positioning part 7 is fixedly connected to the first clamping part 6, the temple body 5, and the second clamping part 10. This integrated connection method ensures the effective transmission of force between the components. When the temple is subjected to external force, the force can be transmitted through the temple body 5 to the first clamping part 6 and the second clamping part 10, and then through the positioning part 7 to the lens connecting groove 3, so that the force is evenly distributed throughout the entire structure, avoiding component damage caused by local stress concentration, and enhancing the overall strength of the temple-lens connection structure.
[0049] The threaded hole 8 is provided only on the side of the first clamping part 6 facing the lens body 1, that is, the threaded hole is a blind hole design. This design allows the fastening screw 9 to be inserted into the connecting hole 2 from the rear side of the lens body 1 and tightened with the threaded hole 8, without the front end of the screw protruding through the front end of the first clamping part 6. This avoids the problem of the screw head or shank protruding from the front end of the clamping part, which affects the aesthetics, and further improves the cleanliness of the glasses' appearance.
[0050] The widths of the first clamping part 6 and the second clamping part 10 are greater than the width of the positioning part 7. The widths of the first clamping part 6 and the second clamping part 10 are greater than the width of the connecting groove 3, so that the lens body 1 is clamped and restricted between the first clamping part 6 and the second clamping part 10.
[0051] 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.
