Description

Technical Field

[0001] This invention relates to the field of eyewear technology, specifically to an adjustable eyewear structure. Background Technology

[0002] In daily life, people often encounter unexpected situations where eyeglass frames break, such as during sports or due to accidental compression. If suitable replacement glasses cannot be found promptly, it can severely impair vision and cause significant disruption to daily life, work, and study. Furthermore, traditional eyeglass structures present numerous inconveniences in lens installation and fixation, with cumbersome and complex procedures that hinder quick lens removal and replacement, and are unable to meet users' needs for rapid lens replacement in emergencies. Additionally, traditional eyeglasses have poor adaptability to different lens sizes, failing to effectively fix lenses according to their actual size, thus limiting their usability. Moreover, individual facial features differ, leading to varying requirements for the distance between the two lenses, but traditional eyeglass structures cannot flexibly adjust the spacing between the lenses within the frame, resulting in poor comfort for many users. Therefore, an adjustable eyeglass structure is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable eyeglass structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adjustable eyeglass structure, comprising an eyeglass frame and two temples, the temples being respectively disposed on both sides of the eyeglass frame; the eyeglass frame comprising a crossbeam, with two frames symmetrically disposed below the crossbeam, the upper sides of the two frames being connected to the crossbeam; each of the two frames having a mounting groove with a downward opening for mounting lenses; a groove being formed on the side wall of the mounting groove; a rotating rod being disposed on both sides of the groove; the upper end of the rotating rod being rotatably connected to the groove; and a clamping block being fixed to the lower end of the rotating rod; the clamping block having a support groove. The upper end of the rotating rod is provided with a gear, and a U-shaped sliding frame is slidably connected to the frame by a spring. Both sides of the sliding frame are provided with toothed rods, and both toothed rods are meshed with the gear on the same side. When the sliding frame slides downwards, the rack drives the gear to rotate, and the lower end of the rotating rod rotates toward the mounting groove, so that the clamping block clamps the lens in the mounting groove. When the sliding frame slides upward, the rack on the sliding frame drives the gear to rotate, causing the lower end of the rotating rod to rotate into the groove.

[0005] Preferably, two frames are slidably connected inside a crossbeam, and a lead screw is rotatably connected inside the crossbeam. The two frames are respectively meshed with the two ends of the lead screw, and the threads at the two ends of the lead screw are arranged in opposite directions. When the lead screw rotates, the two frames will slide synchronously toward the middle of the crossbeam or away from the crossbeam, and both ends of the lead screw penetrate the side wall of the crossbeam and are fixed with a drive head. When the lead screw is driven to rotate by the drive head, the lead screw drives the two frames to move relative to or away from each other.

[0006] Preferably, it also includes a snap-fit ​​assembly for snapping the sliding frame. Each sliding frame has a snap-fit ​​assembly on both sides. The snap-fit ​​assembly includes a swing rod. The lower end of the swing rod is rotatably connected to the side wall of the sliding frame. An elastic plate is fixed on the side wall of the sliding frame. An elastic fork is provided on the elastic plate. The upper end of the elastic fork is pressed against the inner side wall of the swing rod. The upper outer wall of the swing rod is fixed with a locking block, and the side wall of the frame is provided with a locking groove, and the locking block is movably engaged in the inside of the locking groove.

[0007] Preferably, a rotating plate is provided in the middle of the sliding frame, and the middle of the rotating plate is rotatably connected to the side wall of the sliding frame. Both the upper and lower ends of the rotating plate are rotatably connected to a pull rod, and the two pull rods are respectively rotatably connected to the upper ends of two swing rods on the same sliding frame. A protruding column is fixed on the tie rod located below the rotating plate, and a stop bar for blocking the protruding column is fixed on the side wall of the crossbeam.

[0008] Preferably, the clamping block is made of rubber, and multiple hollow elongated holes are evenly formed on the side wall of the clamping block, with the ends of the multiple elongated holes near the mounting groove tilting upwards.

[0009] Preferably, a rear cover is provided on the rear side of the crossbeam, a mating groove is provided on the side wall of the crossbeam, and a mating rib is provided on the side wall of the rear cover. When the back cover is installed on the crossbeam, the mating ribs are inserted into the inside of the mating groove.

[0010] Preferably, both ends of the back cover are fixed with hinge blocks, and the two temples are respectively hinged to the two hinge blocks. The ends of the temples are provided with rotating grooves that cooperate with the hinge blocks. Under the configuration of the rotating grooves and the hinge blocks, the temples can be folded and opened.

[0011] Preferably, a nose pad is provided in the middle of the crossbeam. The nose pad can be made of silicone material, which can increase the comfort of wearing it.

[0012] Compared with existing technologies, the advantages of this invention are as follows: This invention allows the locking block to disengage from the slot by pressing the swing rod. The sliding frame moves upward under the action of a spring, and the lower end of the rotating rod rotates into the groove, opening the mounting slot for easy lens insertion. Sliding the sliding frame downward brings the locking block closer to the lens; releasing the swing rod allows the locking block to engage with the slot, completing the fixation. The operation is simple and efficient. Multiple slots are arranged in an array, allowing the locking block to be inserted into the corresponding slot according to different lens sizes, achieving adaptable fixation for various lens sizes and enhancing the device's versatility. Simultaneously, this structure allows for flexible adjustment of the distance between the lenses within the two frames. Rotating the drive head rotates the lead screw; because the threads at both ends of the lead screw are in opposite directions, the two frames slide synchronously towards the center or sides, meeting the lens spacing needs of different users and improving wearing comfort.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-11 This invention provides a technical solution: an adjustable eyeglass structure, including an eyeglass frame 1 and two temples 2, the temples 2 being respectively disposed on both sides of the eyeglass frame 1. The eyeglass frame 1 includes a crossbeam 101, and two frames 102 are symmetrically disposed below the crossbeam 101. The upper sides of the two frames 102 are connected to the crossbeam 101. Each of the two frames 102 has a mounting groove 1021 with a downward opening for mounting lenses. A groove 1022 is formed on the side wall of the mounting groove 1021. A rotating rod 3 is disposed on both sides of the groove 1022. The upper end of the rotating rod 3 is rotatably connected to the groove 1022. A clamping block 4 is fixed to the lower end of the rotating rod 3. A support groove 401 is formed on the clamping block 4. The upper end of the rotating rod 3 is provided with a gear 301. A U-shaped sliding frame 5 is slidably connected to the frame 102 by a spring 6. The upper end of the spring 6 abuts against the side wall of the sliding frame 5, and the lower end of the spring 6 abuts against the side wall of the frame 102. When the sliding frame 5 slides downward, the sliding frame 5 will compress the spring 6. Both sides of the sliding frame 5 are provided with toothed rods 501, and both toothed rods 501 are meshed with the gear 301 on the same side. When the sliding frame 5 slides downward, the rack 501 drives the gear 301 to rotate, and the lower end of the rotating rod 3 rotates toward the mounting groove 1021, so that the clamping block 4 clamps the lens in the mounting groove 1021. When the sliding frame 5 slides upward, the toothed rod 501 on the sliding frame 5 drives the gear 301 to rotate, causing the lower end of the rotating rod 3 to rotate into the groove 1022.

[0017] like Figures 1-6 As shown, in order to adjust the distance between the lenses inside the two frames 102, specifically, the two frames 102 are slidably connected inside the crossbeam 101. The crossbeam 101 is rotatably connected to a lead screw 8. The two frames 102 are respectively meshed with the two ends of the lead screw 8. The threads at the two ends of the lead screw 8 are arranged in opposite directions. When the lead screw 8 rotates, the two frames 102 will slide synchronously toward the middle of the crossbeam 101 or away from the crossbeam 101. Both ends of the lead screw 8 penetrate the side wall of the crossbeam 101 and are fixed with a drive head 801. When the lead screw 8 is driven to rotate by the drive head 801, the lead screw 8 drives the two frames 102 to move relative to or away from each other.

[0018] like Figures 6-9 As shown, in order to fix the clamping block 4 in the state of clamping the lens, specifically, it also includes a clamping assembly 9 for clamping the sliding frame 5. Each sliding frame 5 is provided with a clamping assembly 9 on both sides. The clamping assembly 9 includes a swing rod 901. The lower end of the swing rod 901 is rotatably connected to the side wall of the sliding frame 5. An elastic sheet 903 is fixed on the side wall of the sliding frame 5. An elastic fork 904 is provided on the elastic sheet 903. The upper end of the elastic fork 904 is spring-pressed on the inner side wall of the swing rod 901. The upper outer wall of the swing rod 901 is fixed with a locking block 902, and the side wall of the frame 102 is provided with a locking groove 905, and the locking block 902 is movably locked inside the locking groove 905. In addition, multiple slots 905 are arrayed. When the card block 902 is engaged in different slots 905, lenses of different sizes can be fixed. The lower the slot 902 is engaged in, the smaller the lens can be fixed in the mounting slot 1021.

[0019] This device can be placed in public areas, with multiple units clustered together (similar to the rental model of public power banks). When an eyeglass frame is damaged, a user selects one of these devices, removes the lens, and installs it on the device for temporary wear. The specific operation process is as follows: First, after finding a suitable device, the user presses the upper end of the swing rod 901 towards the sliding frame 5, causing the elastic fork 904 to deform under pressure. When the upper end of the swing rod 901 swings towards the sliding frame 5, the locking block 902 disengages from the locking groove 905. At this time, the sliding frame 5 slides upward under the elastic force of the spring 6. The toothed rod 501 drives the gear 301 to rotate, and the lower end of the rotating rod 3 rotates into the groove 1022, leaving the mounting groove 1021 in an open state. Next, the removed lens is placed into the mounting slot 1021. Based on the lens size, the sliding frame 5 is slid downwards. The gear 501 drives the gear 301 to rotate in the opposite direction, and the clamping block 4 at the lower end of the rotating rod 3 gradually moves closer to the lens. When the clamping block 4 is in contact with the edge of the lens, the swing rod 901 is released, the elastic fork 904 springs back, and the swing rod 901 is pushed to make the locking block 902 engage in the corresponding slot 905, thus completing the lens fixation. If the lens spacing is not suitable, the drive head 801 can be rotated to drive the lead screw 8 to rotate. Since the threads at both ends of the lead screw 8 are in opposite directions, the two frames 102 will slide synchronously towards the center or sides until a suitable spacing is achieved to meet the user's wearing needs.

[0020] like Figures 6-9 As shown, in order to facilitate the removal of the lens in the mounting slot 1021, specifically, a rotating plate 10 is provided in the middle of the sliding frame 5. The middle of the rotating plate 10 is rotatably connected to the side wall of the sliding frame 5. Both the upper and lower ends of the rotating plate 10 are rotatably connected to a pull rod 11. The two pull rods 11 are respectively rotatably connected to the upper ends of two swing rods 901 on the same sliding frame 5. Among them, a protruding post 12 is fixed on the pull rod 11 located below the rotating plate 10, and a stop bar 13 for blocking the protruding post 12 is fixed on the side wall of the crossbeam 101.

[0021] When the user slides the sliding bracket 5 downwards to fix the lens via the clamping block 4, if the sliding distance of the sliding bracket 5 is large, the upper part of the swing rod 901 may partially enter the crossbeam 101, which may make lens removal inconvenient. Therefore, the rotating plate 10, pull rod 11, protruding post 12, and stop bar 13 are added to increase the convenience of lens removal. The method is as follows: When disassembling the lens, the user rotates the drive head 801 to rotate the lead screw 8, causing the two frames 102 to slide synchronously towards the end of the crossbeam 101 (i.e., the lens moves outward from the device). As the frames 102, carrying the sliding frame 5, move towards the end of the crossbeam 101, the protrusion 12 fixed on the pull rod 11 below the rotating plate 10 gradually approaches the stop bar 13 and eventually abuts against the stop bar 13. Since the stop bar 13 is fixed to the side wall of the crossbeam 101 and cannot move, the protrusion 12, after being blocked, forces the pull rod 11 below to pull away from the swing rod 901. At this time, the rotating plate 10 rotates about its central pivot point, and the pull rod 11 connected to its upper end pulls the upper end of the swing rod 901 on the other side. The two pull rods 11 pull the upper ends of the two swing rods 901 respectively, causing the elastic fork 904 to be deformed under pressure. The upper end of the swing rod 901 swings towards the sliding frame 5, eventually causing the locking block 902 to disengage from the slot 905, releasing the lock of the sliding frame 5. After the locking block 902 disengages, the sliding bracket 5 slides upward under the elastic force of the spring 6, and the rack 501 drives the gear 301 to rotate in the opposite direction. The clamping block 4 at the lower end of the rotating rod 3 moves away from the lens, and the mounting slot 1021 is reopened, allowing the user to easily remove the lens.

[0022] like Figure 10 As shown, in order to increase the stability of the lens clamping, specifically, the clamping block 4 is made of rubber, and multiple hollow elongated holes 402 are evenly opened on the side wall of the clamping block 4. The ends of the multiple elongated holes 402 near the mounting groove 1021 are inclined upward. When the clamping block 4 clamps the lens, the upper side of the lens abuts against the inside of the groove 1022, and the two clamping blocks 4 abut against the lower sides of the lens respectively. At this time, since the clamping block 4 is made of rubber, when the rotating rod 3 applies a pushing force to the clamping block 4, the clamping block 4 will deform at the position of the elongated hole 402. The deformation of the clamping block 4 can provide a slow clamping of the lens, which can improve the stability of the lens clamping and prevent the lens from being damaged.

[0023] like Figure 3 As shown, in order to open the crossbeam 101 so as to assemble and repair the parts inside the crossbeam 101, specifically, a rear cover 1011 is provided on the rear side of the crossbeam 101, a docking groove 1012 is provided on the side wall of the crossbeam 101, and a docking rib 1013 is provided on the side wall of the rear cover 1011. When the rear cover 1011 is installed on the crossbeam 101, the mating rib 1013 is inserted into the inside of the mating groove 1012.

[0024] like Figure 3As shown, mounting holes are provided on the side walls of both the crossbeam 101 and the mating rib 1013. When the mating rib 1013 is inserted into the mating groove 1012, the mounting holes on the mating rib 1013 and the mounting holes on the crossbeam 101 are aligned. Then, screws are screwed into the mounting holes to fix the back cover 1011 onto the crossbeam 101.

[0025] like Figures 1-4 As shown, in order to connect the two temples 2 to the eyeglass frame 1, specifically, both ends of the back cover 1011 are fixed with hinge blocks 7, and the two temples 2 are respectively hinged to the two hinge blocks 7. The ends of the temples 2 are provided with rotating grooves that cooperate with the hinge blocks 7. Under the cooperation of the rotating grooves and the hinge blocks 7, the temples 2 can be folded and opened.

[0026] Specifically, a nose pad 103 is provided in the middle of the crossbeam 101. The nose pad 103 can be made of silicone material, which can increase the comfort of wearing.
