Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to eyeglasses with a flip-up secondary frame. Background Technology

[0002] Prior to this application, the applicant filed a utility model: a magnetic eyeglass with a variable sub-frame angle (publication number: CN222232818U), which disclosed an eyeglass that uses a combination of a locking mechanism and a locking slot to further protect the connection between the mounting post and the main frame, allowing the sub-frame to be more securely mounted on the main frame, in order to solve the stability problem after the sub-frame is flipped. However, the eyeglass with the above structure still requires the operation of pushing the first drive rod and the second drive rod when flipping the sub-frame. Since the first drive rod and the second drive rod are small in size, the operation of flipping the sub-frame is not convenient enough.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This invention proposes a pair of glasses with a flip-up sub-frame, which solves the aforementioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A pair of glasses with a flip-up sub-frame includes a frame and a sub-frame. The frame and the sub-frame are respectively provided with corresponding first magnets and second magnets. The upper end of the center beam of the sub-frame is formed with an abutting plate that abuts against the upper end of the center beam of the frame. An elastic element is rotatably connected to the end of the abutting plate. The lower end of the elastic element is engaged with the lower end of the center beam of the frame.

[0007] Preferably, the elastic element is made of elastic metal bent into an L-shape. The upper end of the vertical part of the elastic element is rotatably connected to the abutment plate. A snap-fit ​​block located below the center beam of the frame is fixedly connected to the horizontal part of the elastic element. A snap-fit ​​protrusion is formed on the snap-fit ​​block. A first snap-fit ​​groove matching the snap-fit ​​protrusion is opened at the lower end of the center beam of the frame. The snap-fit ​​protrusion is snapped into the first snap-fit ​​groove.

[0008] Preferably, the cross-section of the snap-fit ​​block is L-shaped, the vertical part of the snap-fit ​​block abuts against the inner side of the central beam of the frame, and a sliding groove is provided in the vertical part of the snap-fit ​​block that runs vertically through the vertical part of the snap-fit ​​block, and the vertical part of the elastic member is slidably inserted into the sliding groove.

[0009] Preferably, the snap-fit ​​block is composed of a left half and a right half. The horizontal end of the elastic member is bent to form a limiting part. Each of the left half and the right half is provided with a limiting groove that matches the limiting part. A plurality of snap-fit ​​plates are formed on the right half. A plurality of second snap-fit ​​grooves that match the snap-fit ​​plates are formed on the left half. The right half and the left half are joined together by the snap-fit ​​plates and the second snap-fit ​​grooves, so that the limiting part is kept in the limiting groove.

[0010] Preferably, a positioning groove is provided at the upper end of the central beam of the frame, and a positioning protrusion is formed on the abutment plate that is engaged with and inserted into the positioning groove.

[0011] Preferably, the upper end of the frame has several limiting protrusions, and the sub-frame has several limiting holes that correspond one-to-one with and match the limiting protrusions.

[0012] Preferably, the front end of the horizontal portion of the latching block has a protruding, sliding protrusion that extends beyond the horizontal portion of the latching block.

[0013] In summary, the beneficial effects of this utility model are as follows: when the sub-frame is flipped upward, the abutment plate that moves with the sub-frame pulls the elastic element upward, causing the elastic element to deform. The restoring force generated by the deformation of the elastic element applies a downward pulling force to the sub-frame through the abutment plate, so that the sub-frame is tightly pressed against the upper end of the frame, ensuring the stability of the sub-frame after flipping. Moreover, the operation is very simple, and you only need to flip the sub-frame normally. Attached Figure Description

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] As shown in the figure, a pair of glasses with a flip-up sub-frame 2 includes a frame 1 and a sub-frame 2. The frame 1 and the sub-frame 2 are respectively provided with a first magnet 11 and a second magnet 21. The upper end of the center beam of the sub-frame 2 is formed with an abutting plate 22 that abuts against the upper end of the center beam of the frame 1. An elastic member 3 is rotatably connected to the end of the abutting plate 22. The lower end of the elastic member 3 is engaged with the lower end of the center beam of the frame 1.

[0025] Specifically, the structure in which the lower end of the elastic element 3 is engaged with the central beam of the frame 1 is as follows: the elastic element 3 is bent into an L-shape by elastic metal, the upper end of the vertical part of the elastic element 3 is rotatably connected to the abutment plate 22, and the horizontal part of the elastic element 3 is fixedly connected to a engaging block 4 located below the central beam of the frame 1. The engaging block 4 has an engaging protrusion 41 formed on it. The lower end of the central beam of the frame 1 is provided with a first engaging groove 12 that matches the engaging protrusion 41. The engaging protrusion 41 is engaged into the first engaging groove 12. The engaging block 4 and the central beam of the frame 1 are engaged through the cooperation of the engaging protrusion 41 and the first engaging groove 12, thereby realizing the engagement of the lower end of the elastic element 3 with the central beam of the frame 1.

[0026] In the above structure, when the sub-frame 2 is placed on the front side of the frame 1, the first magnet 11 and the second magnet 21 attract each other, causing the sub-frame 2 to adhere to the front side of the frame 1. At the same time, the abutment plate 22 is placed on the upper end of the center beam of the frame 1. Then, the locking block 4 is swung, causing the elastic element 3 to swing. The locking block 4 passes around the center beam of the frame 1 from the rear side, and the elastic deformation of the elastic element 3 causes the locking protrusion 41 to engage with the first locking groove 12. At this time, the abutment plate 22, the elastic element 3, and the locking block 4 form a structure that is clamped on the center beam of the frame 1, which enhances the stability of the sub-frame 2 adhering to the front side of the frame 1. When it is necessary to temporarily flip the sub-frame 2, the sub-frame 2 is slightly pushed upward, so that the upper end of the sub-frame 2 protrudes slightly from the upper end of the frame 1, allowing the sub-frame 2 to abut against the upper end of the frame 1 and flip upward to a position perpendicular to the frame 1. During the movement and flipping process, the abutment plate 22, which moves and swings with the sub-frame 2, stretches the vertical part of the elastic element 3 upward, causing the elastic element 3 to deform. The restoring force generated by the deformation of the elastic element 3 applies a downward pulling force to the sub-frame 2 through the abutment plate 22 when the sub-frame 2 swings to a position perpendicular to the frame 1. The pulling force of the elastic element 3 makes the sub-frame 2 press tightly against the frame 1, thus achieving the positioning of the sub-frame 2 after flipping. This keeps the sub-frame 2 stably at the upper end of the frame 1. When it is necessary to reattach the sub-frame 2 to the front side of the frame 1, the sub-frame 2 is pushed downward, and the sub-frame 2 is flipped back to its original position under the restoring force of the elastic element 3. Through the above structure and method, the stability of the sub-frame 2 is ensured when it is attached to the front side of the frame 1 and when it is flipped to the upper end of the frame 1. Moreover, the operation is very simple, and the sub-frame 2 can be flipped normally.

[0027] Furthermore, based on the above structure, the cross-section of the locking block 4 is L-shaped. The vertical part of the locking block 4 abuts against the inner side of the central beam of the frame 1, and a sliding groove 42 is formed in the vertical part of the locking block 4, which runs vertically through the vertical part. The vertical part of the elastic member 3 is slidably inserted into the sliding groove 42. After the locking protrusion 41 is engaged in the first locking groove 12, the vertical part and the horizontal part of the locking block 4 abut against the inner side and the lower end face of the central beam of the frame 1, respectively, which enhances the stability of the locking block 4 after it is engaged with the central beam of the frame 1, thus strengthening the... To ensure the stability of the connection between the elastic element 3 and the central beam of the frame 1, during the process of the elastic element 3 being deformed by the abutment plate 22 pulling the elastic element 3 vertically upward, the vertical part of the elastic element 3 remains within the sliding groove 42 and moves longitudinally. The sliding groove 42 constrains the movement of the vertical part of the elastic element 3 and keeps it in the longitudinal direction. This also keeps the tension applied by the elastic element 3 to the sub-frame 2 through the abutment plate 22 in the longitudinal direction, avoiding the force deviation that would cause the sub-frame 2 to wobble when placed on the upper end of the frame 1, thereby ensuring the stability of the sub-frame 2 when it is flipped and placed on the upper end of the frame 1.

[0028] Furthermore, based on the above structure, the snap-fit ​​block 4 is composed of a left half 43 and a right half 44 joined together. The horizontal end of the elastic member 3 is bent to form a limiting part 31. Each of the left half 43 and the right half 44 has a limiting groove 45 that matches the limiting part 31. The right half 44 has several snap-fit ​​plates 441 formed on it, and the left half 43 has several second snap-fit ​​grooves 431 that match the snap-fit ​​plates 441. The right half 44 and the left half 43 are snap-fitted together. The plate 441 and the second snap-fit ​​groove 431 are engaged to keep the limiting part 31 in the limiting groove 45. The engagement of the limiting part 31 and the limiting groove 45 achieves the fixed connection between the horizontal part of the elastic element 3 and the snap-fit ​​block 4. The snap-fit ​​block 4 is divided into a left half 43 and a right half 44 for easy assembly and disassembly of the elastic element 3 on the snap-fit ​​block 4. When the elastic element 3 experiences elastic fatigue after long-term use, it is easy to replace the elastic element 3 to ensure its performance and thus ensure the stability of the sub-frame 2 after flipping.

[0029] Furthermore, based on the above structure, a positioning groove 13 is provided at the upper end of the central beam of the frame 1, and a positioning protrusion 23 is formed on the abutment plate 22 and engages with the positioning groove 13. When the abutment plate 22 abuts against the upper end of the central beam of the frame 1, the positioning protrusion 23 engages with the positioning groove 13. Through the cooperation between the positioning protrusion 23 and the positioning groove 13, the stability of the abutment plate 22 when it abuts against the central beam of the frame 1 is enhanced, and the position of the abutment plate 22 on the central beam of the frame 1 is also positioned, so that the engaging protrusion 41 is accurately aligned with the first engaging groove 12, making it easier for the engaging protrusion 41 to engage with the first engaging groove 12, which facilitates operation.

[0030] Furthermore, based on the above structure, the upper end of the frame 1 is provided with several limiting protrusions 14, and the sub-frame 2 is provided with several limiting holes 24 that correspond one-to-one with the limiting protrusions 14. The center of the limiting protrusions 14 is located behind the axis of rotation of the abutment plate 22 and the elastic member 3. When the sub-frame 2 is flipped to a position perpendicular to the frame 1 and placed on the upper end of the frame 1, the sub-frame 2 is pulled upward to insert the limiting protrusions 14 into the limiting holes 24. The limiting protrusions 14 are held in the limiting holes 24 by the pulling force applied to the sub-frame 2 by the elastic member 3. The cooperation between the limiting protrusions 14 and the limiting holes 24 limits the flipping of the sub-frame 2, thereby enhancing the stability of the sub-frame 2 when it is flipped and placed on the upper end of the frame 1. When resetting the sub-frame 2, the limiting protrusions 14 are pulled upward to exit the limiting holes 24.

[0031] Furthermore, based on the above structure, the front end of the horizontal part of the locking block 4 is formed with a protruding actuating protrusion 46 that protrudes from the horizontal part of the locking block 4. When it is necessary to remove the sub-frame 2 from the mirror frame 1, the locking block 4 can be more easily moved by pushing the protruding protrusion 46 to make the locking protrusion 41 exit from the first locking groove 12, thereby removing the sub-frame 2 from the mirror frame 1, which facilitates the operation of separating the sub-frame 2 from the mirror frame 1.

[0032] 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.
