Description

Technical Field

[0001] This utility model relates to the field of eyeglass accessories technology, and in particular to an adjustable nose pad structure. Background Technology

[0002] When wearing glasses, nose pads are a common support component that works with the bridge of the nose. Properly designed nose pads can help glasses stay in place and prevent them from slipping off.

[0003] Traditional nose pads are fixed and cannot be adjusted according to different nose bridge shapes and sizes. Some adjustable nose pads have a more complex structure and cannot achieve multiple positioning positions, resulting in poor adaptability and failing to meet the user's wearing needs. Utility Model Content

[0004] The purpose of this utility model is to provide an angle-adjustable nose pad structure, in which the rotating seat with the nose pad body is detachable and rotatably mounted on the fixed seat, and the two have a multi-level positioning structure, which can realize the quick assembly and disassembly of the nose pad body relative to the lens and multi-angle positioning.

[0005] To achieve the above objectives, the solution of this utility model is: an angle-adjustable nose pad structure, including a nose pad body, a rotating seat, and a fixing seat fixed on the lens; The top of the fixed seat has a fixed rotating shaft, the top of the rotating seat is connected to the nose pad body, and the bottom is provided with a rotating groove. The rotating groove is rotatably engaged with the fixed rotating shaft on the fixed seat, so that the rotating seat rotates relative to the fixed seat around the fixed rotating shaft. A multi-level positioning structure is also provided between the fixed seat and the rotating seat. The multi-level positioning structure includes a protruding ridge at the bottom of the fixed seat and a retaining seat at the bottom of the rotating seat. The retaining seat has multiple retaining slots, which are spaced apart along the rotation direction of the rotating seat. When the rotating seat rotates, it drives the different retaining slots on the retaining seat to engage with the protruding ridge, thereby positioning the rotating seat and the nose pad body on it at different angles.

[0006] Furthermore, the axes of the protruding ridge and the slot are both parallel to the axis of the fixed rotating shaft.

[0007] Furthermore, the cross-section of the card holder is wavy, with the troughs of the wavy card holder forming card slots and the crests forming protrusions.

[0008] Furthermore, the cross-sections of the protruding ridges, slots, and protrusions are all arc-shaped.

[0009] Furthermore, the rotating seat and the fixed seat are detachably connected, and the connection between the fixed seat and the rotating seat is deformable. The rotating groove of the rotating seat can be engaged with or disengaged from the fixed rotating shaft of the fixed seat under the action of external force.

[0010] Furthermore, the radial opening size of the rotating groove of the rotating seat is smaller than the diameter of the fixed rotating shaft on the fixed seat.

[0011] Furthermore, the bottom of the fixing base is a trapezoidal base, the lower base of the trapezoidal base is connected to the lens, the upper base is connected to the fixing shaft, and the opening of the rotating groove extends outward to form a trapezoidal groove for the trapezoidal base to be inserted.

[0012] Furthermore, the mounting base is integrally formed with the lens.

[0013] Furthermore, the nose pad body includes a left nose pad body and a right nose pad body, and each of the left nose pad body and the right nose pad body is connected to a rotating seat.

[0014] Furthermore, there are two fixing seats, which are arranged at an angle of V on the lens.

[0015] After adopting the above solution, the beneficial effects of this utility model are as follows: The nose pad structure in this case includes a fixed base, a rotating base, and a nose pad body. The nose pad body is set on the rotating base. The rotating groove of the rotating base cooperates with the fixed rotating shaft on the fixed base, so that the rotating base rotates relative to the fixed base with the fixed rotating shaft as the rotating axis, thereby realizing the multi-angle rotation of the nose pad body. To ensure the nose pad is positioned at the adjusted angle, this design incorporates a multi-stage positioning structure between the rotating base and the fixed base. When the angle of the nose pad needs adjustment, external force is applied to rotate the nose pad to the desired angle, and the multi-stage positioning structure then positions it, making it suitable for wearers with different nose shapes and sizes, thus offering good versatility.

[0016] Furthermore, the rotating base and the fixed base can be designed as a detachable connection. During use, the rotating groove of the rotating base and the fixed shaft of the fixed base are assembled and disassembled by pressing and pulling with external force, which can realize the quick installation and removal of the nose pad body, thus facilitating the replacement and storage of the nose pad body.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] This utility model provides a nose pad structure with an adjustable angle. For example... Figures 1 to 8 As shown, it includes a nose pad body 1, a rotating base 2, and a fixed base 3.

[0021] The mounting base 3 is fixed to the lens 5, and there are many ways to fix it, such as snap-fit ​​connection and screw fastening. This case does not limit the fixing method between the two. In this embodiment, the nose pad structure is applied to the goggles, so the mounting base 3 and the lens 5 are integrally injection molded.

[0022] like Figures 2 to 4 As shown, the top of the fixed base 3 is a cylindrical fixed pivot 31, and the bottom is a trapezoidal base 32. The lower bottom of the trapezoidal base 32 is connected to the lens 5, and the upper bottom is connected to the fixed pivot 31.

[0023] The top of the rotating seat 2 is connected to the nose pad body, and the bottom of the rotating seat 2 is connected to the fixed seat, thereby mounting the nose pad on the lens. This design utilizes a rotating shaft and groove mating structure to achieve a rotatable connection between the rotating seat 2 and the fixed seat 3, allowing the nose pad body 1 to rotate relative to the fixed seat 3 around the lens 5, thus achieving angle adjustment of the nose pad body 1. Specifically: [Example...] Figures 2 to 7 As shown, the bottom of the rotating seat 2 is provided with a rotating groove 21, which is rotatably engaged with the fixed rotating shaft 31 on the fixed seat 3, so that the rotating seat 2 rotates relative to the fixed seat 3 around the fixed rotating shaft 31. The radial opening of the rotating groove 21 of the rotating seat 2 is smaller than the diameter of the fixed rotating shaft 31 to prevent the fixed rotating shaft 31 from disengaging from the rotating groove 21.

[0024] like Figure 6 and Figure 7As shown, the opening of the rotating groove 21 extends outward to form a trapezoidal groove 22. While the fixed rotating shaft 31 is embedded in the rotating groove 21, the trapezoidal base 32 is also embedded in the trapezoidal groove 22. The trapezoidal groove 22 is larger than the trapezoidal base 32, providing sufficient clearance for the rotation of the rotating seat 2.

[0025] To achieve multi-angle adjustment and positioning of the nose pad body 1, a multi-level positioning structure 4 with a convex-concave fit is provided between the fixed base 3 and the rotating base 2. As shown in the figure, the multi-level positioning structure 4 includes a protruding ridge 41 and a retaining seat 42. Specifically, the protruding ridge 41 is formed by axially extending from the bottom of the fixed base 3, and the axis of the protruding ridge 41 is parallel to the axis of the fixed rotating shaft 31. Correspondingly, the retaining seat 2 forms the retaining seat 42 at the position corresponding to the protruding ridge 41. The retaining seat 42 has multiple retaining grooves 421, which are spaced apart along the rotation direction of the rotating base 2, and the axis of these retaining grooves 421 is parallel to the axis of the fixed rotating shaft 31. When the rotating base 2 rotates, the retaining grooves 421 on the retaining seat 42 move synchronously, and the retaining grooves 421 move into place to engage with the protruding ridge 41, thereby positioning the rotating base 2 and the nose pad body 1 on it at different angles.

[0026] In this embodiment, the card holder 42 is provided with three grooves, such as Figure 6 and Figure 7 As shown, a, b, and c are the first, second, and third slots, respectively, with protrusions 422 formed between adjacent slots. d and e are the first and second protrusions, respectively. This means that the rotating seat 2 and the fixed seat 3 in this embodiment have three angle settings. When adjusting the nose pad angle, the user manually moves the rotating seat 2 to the left or right, causing it to rotate relative to the fixed seat 3. This, in turn, causes the seat 42 to rotate relative to the protrusion 41, disengaging the current slot 421 from the protrusion 41, while the other slot 421 engages with the protrusion 41, thus achieving different angle positioning of the nose pad structure. A more preferred solution is that the cross-section of the seat 42 is wavy, with the troughs of the wavy seat 42 forming the slots 421 and the peaks forming the protrusions 422. Furthermore, the cross-sections of the protrusion 41, slots 421, and protrusions 422 are all arc-shaped, making the sliding misalignment between the protrusion 41 and slots 421 and protrusions 422 smoother when the rotating seat 2 rotates, which is beneficial for adjusting the angle.

[0027] Furthermore, the rotating seat 2 and the fixed seat 3 in this case are detachably connected. Both the rotating seat 2 and the fixed seat 3 are made of plastic material and have a certain degree of deformation. When it is necessary to install the nose pad body 1, align the groove of the rotating seat 2 with the fixed seat 3, and press it firmly to make the rotating groove 21 embed into the fixed rotating shaft 31, using their elasticity to form a press-fit assembly; when it is necessary to replace the nose pad, the nose pad body 1 together with the rotating seat 2 can be pulled away from the fixed seat 3 to achieve quick disassembly and quick installation.

[0028] In this embodiment, the nose pad body 1 is made of silicone, which provides good comfort when in contact with the skin. The nose pad body 1 includes a left nose pad body 11 and a right nose pad body 12, which can be connected as one unit by a bridge; the left nose pad body 11 and the right nose pad body 12 can also be separate, that is, the left and right nose pad bodies are set separately. Separate setting makes it convenient to replace the nose pad body after wear or damage, thereby reducing consumables.

[0029] The left nose pad body 11 and the right nose pad body 12 are each connected to a rotating seat 2. In this embodiment, there are two fixed seats 3, which are arranged at an angle of V on the lens 5. Correspondingly, there are also two rotating seats 2, with one fixed seat 3 corresponding to one rotating seat 2.
