Description

Technical Field

[0001] The present application relates to the technical field of glasses, and in particular to a glasses stud as a connecting piece between a front frame of glasses and a hinge, and specifically to a glasses stud structure capable of adjusting the inner and outer widths of a glasses frame according to the width requirements of a user's face, and glasses equipped with the stud structure. Background Art

[0002] The design and manufacturing technologies of eyeglass spikes on the market can be mainly divided into three categories: (1) Plastic eyeglass frames: integrally molded with the front frame of injection-molded or sheet eyeglasses; (2) Metal eyeglass frames: fixed to the metal frame ring by welding or screws; (3) Plastic frame metal spikes: fixed by injection molding or screws.

[0003] Traditional eyeglass designs are mainly innovative in appearance, materials, and connection methods. However, since the frames and tips are fixed-size parts, the inner and outer widths (face width) of the entire pair of glasses are fixed and do not have an adjustment function. However, there is a certain relationship between the pupil distance between the eyes and the face width of a person's face. Two people with the same pupil distance may need to wear glasses of different sizes because of different face widths. Current glasses do not have a face width adjustment function, so people with different face widths can only adapt to their respective face width requirements by changing to glasses of different sizes.

[0004] The inventor has analyzed and studied the relationship between the frame sizes and found that the distinction of frame sizes mainly depends on three data: lens width, nose bridge length and temple length. For example, in the frame size marking 45-15-138, 45 represents the lens width, 15 represents the nose bridge length, and 138 represents the temple length. 45+15=60, this 60 represents the frame distance between the two frames of the glasses, and the frame distance plus the size of the connection between the head and the frame constitutes the inner and outer width of the glasses frame.

[0005] The selection of frame size is regulated by national standards. When choosing frames, according to national standards, the amount of eccentricity of a single eye should be less than or equal to 3mm. For people with a pupil distance of 60mm, the ideal frame distance should be between 60-66mm. If the face width is normal or small, a frame distance of 60-66mm is just right; if the face width is large, there are only the following two options:

[0006] 1. Or choose glasses with a frame distance of 60-66mm: but the inner and outer widths of the glasses are required to be lengthened. The existing technology achieves this by increasing the length of the connection between the stud and the frame, that is, a design with a small lens ring and a large face width; or, choose a spring structure for the temples to increase the opening and closing angle of the temples; or, choose soft material with a large arc temple to wrap the head, but these methods will affect the wearing comfort and aesthetics.

[0007] 2. Choose a glasses frame with a frame distance greater than 66mm: This will inevitably cause the lens to shift more than 3mm. When the shift exceeds 3mm, the following problems may exist for myopia lenses: the edge of the lens becomes thicker, resulting in heavier weight; the lens shift is too large, and when the lens is processed, the peripheral optical functional area designed around the optical center point of the lens will also be affected, thereby reducing the wearing effect of the functional lens; such as the peripheral defocus area of ​​the defocus lens and the far use area, near use area, and peripheral astigmatism area of ​​the progressive multifocal lens.

[0008] Therefore, when users currently choose glasses, when they choose frames that meet the national standard eccentricity according to the pupil distance, the inner and outer widths of the frames often cannot adapt to the user's facial width requirements, resulting in the user having to compromise between comfort and eccentricity when choosing frames. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the prior art. Summary of the invention

[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] 1. Based on further analysis and research on the existing technical problems, the present application recognizes that when selecting a frame that meets the national standard eccentricity according to the pupil distance, the inner and outer widths of the frame often cannot adapt to the user's face width requirements. For this reason, the present application provides a pile head structure, which achieves targeted length adjustment when fitting glasses through a plurality of limit installation grooves sequentially arranged in the installation groove cavity of the pile head seat and a spring buckle installed on the first connecting section of the pile head adapter. For example, when fitting glasses, the user can choose to meet the national standard eccentricity according to the pupil distance. The frame can be extended or retracted by adjusting the spring buckle in the stud structure and the corresponding limit installation grooves according to the individual's face width, thereby adjusting the inner and outer widths of the frame. The stud structure provided by the present application can further reduce the influence of objective conditions such as the user's face shape and face width on the frame selection when selecting the frame according to the pupil distance. In addition, since the present application realizes the adjustment of the inner and outer widths of the frame through the stud structure, the amount of eccentricity can be minimized when assembling the glasses, thereby improving the refractive performance of the lens.

[0023] 2. In the pile head structure provided in the present application, a long strip through hole is provided on the pile head adapter, and auxiliary mounting grooves are respectively provided on the base and the gusset plate of the pile head seat, the positioning column can be inserted into the long strip through hole, and the two ends of the positioning column are respectively connected to an auxiliary mounting groove, or a mounting hole can be provided at one end or both ends of the positioning column and a connecting column plugged into the mounting hole in one or two auxiliary mounting grooves to achieve reliable plug-in fixation; when the pile head structure is assembled, the base and the gusset plate are in a separate state, the pile head connector is inserted into the base, the spring buckle is first inserted into the pile head adapter so that it can be aligned with the target limit mounting groove on the base or the gusset plate for embedded installation, and then the positioning column is passed through the long strip through hole and one end of it is connected and fixed to the auxiliary mounting groove on the base, and then the gusset plate is connected and fixed to the base; in actual application, if the user has adjusted the target wearing size of the pile head structure, glue can be further injected into the gap between the base and the pile head connector to ensure that the base, the gusset plate and the pile head adapter are firmly connected.

[0024] 3. In the pile head structure provided in the present application, the limit installation groove is arranged opposite to the gusset plate or the limit installation groove is arranged on the base, and the central axis of the positioning column is perpendicular to the plate surface of the gusset plate. This structural arrangement facilitates installation operations.

[0025] 4. In the pile head structure provided in the present application, a plurality of limit installation grooves are arranged at equal intervals on the inner wall of the installation groove cavity. This uniform arrangement facilitates multi-level adjustment.

[0026] 5. In the pile head structure provided in the present application, a limiting protrusion is provided on the inner wall of the closed end of the base, and a limiting groove adapted thereto is provided on the end face of the pile head adapter. The design of the limiting protrusion and the limiting groove can provide limiting means for the aligning and plugging of the pile head adapter and the base.

[0027] 6. In the pile head structure provided in the present application, a locking protrusion is provided at one end of the limiting protrusion on the base that extends out of the notch of the base, and a locking groove that is adapted to be connected to the locking protrusion is provided on the buckle plate. This structural design enables the limiting protrusion to not only assist in the positioning and installation of the pile head adapter, but also assist in the connection and fixation of the buckle plate and the base; in addition, a connecting hole can be provided on the end face of the end of the limiting protrusion on the base that extends out of the notch of the base, and a pin shaft that is adapted to be connected and fixed with the connecting hole can be provided on the buckle plate to achieve reliable connection and fixation.

[0028] 7. In the pile head structure provided in the present application, the pile head seat and the pile head adapter are limited and fixed by a spring buckle. The use of the spring elastic force not only facilitates installation, but also ensures that the limiting bead is reliably embedded and installed in the limiting installation groove in the base through the force of the spring to restore the deformation, thereby ensuring reliable structural fixation. In specific manufacturing and processing, the groove depth of the limiting installation groove can be designed according to the structural dimensions of the limiting bead on the spring buckle to ensure that the spring buckle and the limiting installation groove are reliably embedded and installed and prevent the base and the buckle plate from detaching under the elastic force of the spring itself.

[0029] 8. After the pile head structure provided in the present application is adjusted to the user's target wearing size, it is preferred to use glue to bond and fix the base, the buckle plate and the pile head adapter. Although the connection and fixation between the base, the buckle plate and the pile head adapter can also be achieved by tightening screws, the screw connection method has the defect of being easy to loosen after long-term use, and the screws exposed on the outer surface of the pile head structure also reduce the aesthetics of the glasses. Therefore, the present application uses glue for overall bonding and fixation, which may not only effectively improve the reliability of the structural assembly but also improve the aesthetics of the glasses.

[0030] 9. The present application also provides a pair of glasses, which are equipped with the above-mentioned pile head structure. With the support of the size adjustment function of the pile head structure, the glasses can reduce the amount of eccentricity to a minimum and can meet the wearing needs of users with any face width size. When fitting glasses, the user can choose a frame that meets the national standard eccentricity according to the pupil distance, and then adjust the spring buckle in the pile head structure and the respective limit installation grooves according to the personal face width size to achieve the length extension and contraction of the pile head structure, thereby achieving the inner and outer width size adjustment of the frame to meet the user's wearing needs.

Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be regarded as the scope of this application.

[0046] In order to solve the problems existing in the prior art, the inventors conducted further research on the structure of glasses and found that the inner and outer widths of the frame depend on the dimensions of three positions: 1. The lens width; 2. The size of the bridge of the nose; 3. The size of the connection between the stud and the frame, among which: the lens width is an immutable fixed size because it needs to be assembled with lenses; the size of the bridge of the nose has a too small variable size range from the smallest to the largest, and there is basically no adjustment space; and the size of the connection between the stud and the frame is the most ideal size adjustment area. To this end, the present application improves the structure of the connection between the traditional stud and the frame, and provides a stud structure so that it has a telescopic function, that is, a length adjustable function, and uses a limited structural means to allow the stud structure, which was originally a fixed size, to have a multi-position adjustable function, thereby realizing the adjustable inner and outer widths of the entire pair of glasses frame. The stud structure is described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] Embodiment 1

[0048] This embodiment provides a pile head structure, which solves the problem that when a user wears glasses and selects a frame based on the pupil distance, the size of the frame meets the national standard eccentricity, but the inner and outer widths of the frame cannot adapt to the face shape and width of the human face.

[0049] In this embodiment, see Figure 1 The pile head structure mainly includes a pile head seat 1 and a pile head adapter 2 adapted to be connected with the pile head seat 1. The pile head seat 1 includes a base 11 and a gusset plate 12. Figures 2 to 4 The base 11 is a hollow cylindrical structure with one end closed and the other end open. A notch 111 communicating with the open end is provided on the side wall of the base 11. The gusset plate 12 is adapted to be installed at the notch 111. A plurality of position-limiting installation grooves 112 are provided in sequence along the length direction on the inner wall of the base 11. The pile head adapter 2 includes a first connecting section 21 adapted to be plugged into the inner cavity of the base 11 and a second connecting section 22 connected to the first connecting section 21. An installation hole for installing a spring buckle 211 is provided at one end of the first connecting section 21 away from the second connecting section 22. A hinge seat 221 adapted to be connected to the temple of the glasses is provided at one end of the second connecting section 22 away from the first connecting section 21. The spring buckle 211 can be adapted to be installed in each position-limiting installation groove 112.

[0050] The pile head structure provided in the above embodiment is adapted for limited installation through a plurality of limit installation grooves 112 arranged in sequence in the base 11 and a spring buckle 211 installed on the first connecting section 21 of the pile head adapter 2. When fitting glasses, the user can choose a frame 31 that meets the national standard eccentricity according to the pupil distance, and can adjust the spring buckle 211 in the pile head structure and the respective limit installation grooves 112 according to the personal face width to achieve the length extension and contraction of the pile head structure, thereby achieving the adjustment of the inner and outer width dimensions of the frame 31.

[0051] In a preferred embodiment of the present application, see Figure 2 , 3, the first connecting section 21 is provided with a long strip through hole 212, and the long strip through hole 212 is close to the second connecting section 22. At the same time, an auxiliary installation groove is provided on the inner wall of the base 11, and the auxiliary installation groove is used to plug and fix the positioning column 113. When the positioning column 113 is inserted into the long strip through hole 212, one end of the positioning column 113 is connected and fixed with the auxiliary installation groove on the base 11, and the other end of the positioning column 113 passes through the long strip through hole 212 and is correspondingly plugged and fixed with the auxiliary installation groove on the gusset plate 12. The arrangement of the positioning column 113 and the strip through hole can not only realize the connection and positioning, but also play the role of connecting the base 11, the pile head adapter 2 and the gusset plate 12 through the auxiliary installation groove to realize the structural fixation. In order to ensure that the pile head structure has a larger size adjustment function, the auxiliary installation groove on the base 11 is close to the open end of the base 11, and accordingly, the end of the long strip through hole 212 close to the second connecting section 22 should also correspond to the position of the auxiliary installation groove.

[0052] In a preferred embodiment of the present application, the base 11 is a hollow cuboid with one end open and the other end closed, and a side wall of the base 11 forms a notch 111 for mounting the gusset plate 12, and the gusset plate 12 is a rectangular plate that is adapted to be connected with the notch 111 of the base 11. Of course, in other embodiments, the base 11 may also be a cylindrical body, a polygonal cylindrical body, etc., with one end open and the other end closed and the notch 111 provided on the side wall.

[0053] When assembling the pile head structure provided in the above embodiment, the base 11 and the buckle plate 12 are in a separate state. The pile head connector is inserted into the base 11. The spring buckle 211 is first passed through the pile head adapter 2 and embedded and installed in alignment with the limiting installation groove 112 on the base 11. Then, the positioning column 113 is passed through the long strip through hole 212 and one end of it is connected and fixed to the auxiliary installation groove on the base 11, and then the buckle plate 12 is connected and fixed to the base 11.

[0054] In actual applications, if the user has adjusted the target wearing size of the pile head structure, the base 11, the buckle plate 12 and the pile head adapter 2 can be further firmly connected by means of glue injection or screw fastening.

[0055] In a preferred embodiment of the present application, the limiting installation groove 112 provided on the inner wall of the base 11 is arranged opposite to the buckle plate 12, and the central axis of the positioning column 113 is perpendicular to the plate surface of the buckle plate 12. This structural design facilitates installation operations.

[0056] In a preferred embodiment of the present application, see Figure 4Two limit installation grooves 112 are arranged on the inner wall of the base 11, and the two limit installation grooves 112 are arranged at equal intervals in sequence along the length direction of the base 11. The two limit installation grooves 112 are designed one on the left and one on the right, respectively constituting the first gear size adjustment position and the second gear size adjustment position. When wearing glasses, the spring buckle 211 can be installed in one of the limit installation grooves 112 according to the width of the user's face. A pair of glasses can have two inner and outer width sizes of the frame 31, which can meet the wearing needs of users with different face widths.

[0057] In a preferred embodiment of the present application, see Figure 3 , 4 A limiting protrusion 114 is provided on the inner wall of the base 11. The limiting protrusion 114 is a convex block structure protruding from the closed end to the open end of the base 11. A limiting groove 213 is provided on the end surface of the first connecting section 21 away from the second connecting section 22 to be matched with the limiting protrusion 114. The design of the limiting protrusion 114 and the limiting groove 213 can provide a limit for the alignment and insertion of the pile head adapter 2 and the base 11.

[0058] In a preferred embodiment of the present application, the above-mentioned limiting protrusion 114 is in the shape of a long strip, and the length direction of the limiting protrusion 114 is perpendicular to the plate surface of the gusset plate 12. One end of the limiting protrusion 114 extends to the notch 111 on the base 11 and after extending out of the notch 111, the gusset 1141 at its end is adapted to connect with the slot 121 on the gusset plate 12. This structural design enables the limiting protrusion 114 to not only assist the pile head adapter 2 in positioning and installing, but also assist the gusset plate 12 and the base 11 in connecting and fixing.

[0059] In a preferred embodiment of the present application, see Figure 2 The spring buckle 211 includes a spring 2111 and a limit bead 2112 disposed at one end of the spring 2111. The limit bead 2112 is adapted to be embedded in the limit installation groove 112 in the base 11. The limit installation groove 112 is a truncated cone-shaped groove provided on the inner wall of the base 11. The present application realizes the limit fixation of the pile head seat 1 and the pile head adapter 2 through the spring buckle 211. The use of the spring elastic force is not only convenient for installation, but also can ensure that the limit bead 2112 is reliably embedded in the limit installation groove 112 in the base 11 through the force of the spring to restore the deformation, thereby ensuring reliable structural fixation.

[0060] In a preferred embodiment of the present application, a gap for filling with glue is formed between the outer wall of the first connecting section 21 and the inner wall of the base 11; the base 11, the first connecting section 21 and the buckle plate 12 are fixed by bonding with glue.

[0061] In actual applications, after the pile head structure is adjusted to the user's target wearing size, it is preferably necessary to use glue to bond and fix the base 11, the buckle plate 12 and the pile head adapter 2. Although the connection and fixation between the base 11, the buckle plate 12 and the pile head adapter 2 can also be achieved by tightening screws, the screw connection method has the defect of being easy to loosen after long-term use, and the screws exposed on the outer surface of the pile head structure also reduce the aesthetics of the glasses. Therefore, the use of glue for overall bonding and fixation in this application may not only effectively improve the reliability of the structural assembly but also improve the aesthetics of the glasses.

[0062] In summary, the pile head structure provided by the present application can realize the length extension of the pile head structure through the alignment installation of the spring buckle 211 and each limit installation groove 112, thereby realizing the adjustment of the inner and outer width size of the frame 31. The pile head structure provided by the present application can further reduce the influence of objective conditions such as the user's face shape and face width on the selection of the frame 31 when selecting the glasses frame 31 according to the pupil distance. In addition, since the present application realizes the size adjustment of the inner and outer width of the frame 31 through the pile head structure, the amount of eccentricity can be reduced to a minimum when assembling glasses. Since all the optical function designs of the lens are around the optical center point of the lens, the default optical center point corresponds to the pupil of the human eye. Since the present application can reduce the amount of eccentricity to a minimum, the optical function of the lens periphery can be brought into play to the best, such as increasing the myopic defocus effect of the defocus lens, increasing the peripheral field of view imaging effect of the progressive multifocal lens, etc. Therefore, the present application can reduce the amount of eccentricity to a minimum, which means that the refractive performance of the lens can be improved.

[0063] Furthermore, various academic studies have shown that Asians and Europeans have different skull shapes, and the front face width of Asians is significantly larger than that of Europeans and Americans. Therefore, the post structure provided in the present application can change the inner and outer widths of the frame through the adjustment function of the post structure without changing the lens width of the frame, thereby realizing the face width adjustment function of the glasses. Therefore, glasses equipped with the post structure provided in the present application can better meet the face width wearing needs of Asians.
