Description

Technical Field

[0001] This utility model relates to the field of optical lens frame technology, and in particular to an adjustable optical lens frame connecting device. Background Technology

[0002] Optical frames are an essential component of eyeglasses, primarily used to hold lenses in place. They typically consist of two parts: the frame and the temples. The frame holds the lenses and comes in various shapes, including round, square, oval, and other geometric forms, as well as fashionable irregular designs to meet diverse aesthetic needs. However, the lenses are connected using a connecting device, a key component designed to enhance the frame's flexibility and adaptability. For example, some adjustable connecting devices utilize a special hinge structure with multiple movable joints. These joints allow the temples to be adjusted in multiple dimensions, expanding outwards or retracting inwards to accommodate different head shapes. The adjustment mechanism includes an adjustable adjusting element and a rotating support. As the adjusting element moves on the temple, it changes the maximum angle between the temple and frame, improving the eyeglasses' versatility. However, during use, the frame still needs to be adjusted to fit different users.

[0003] Existing adjustable optical frame connection devices consist of hinges, bolts, and pins. The connection mechanism is the core part that enables flexible connection and adjustment of various components. Taking the connection mechanism between the temple and the frame as an example, the most common is the hinge-type connection mechanism, which is generally composed of multiple metal plates connected by pins. There is a certain amount of play between these metal plates. When it is necessary to adjust the angle of the temple, the metal plates rotate around the pins, so that the temple expands outward or retracts inward. Some high-end frames use a precise multi-axis design for the hinge, which allows the temple to be finely adjusted in both horizontal and vertical directions to adapt to the facial contours and habits of different wearers, greatly improving wearing comfort. However, this adjustment method can only make fine adjustments to the direction of the temple and cannot adjust the width between the lenses. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable optical frame connecting device, which aims to improve the problem that the existing adjustment method can only make fine adjustments to the temple in the direction, and cannot adjust the width between the lenses.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable optical frame connecting device, including a frame, a moving plate fixedly connected to the middle of the frame, a spring three fixedly connected to the right side of the moving plate, a connecting post slidably connected inside the spring three, a baffle fixedly connected to the middle of the connecting post, multiple fixed posts fixedly connected to the front right side of the moving plate, a sliding plate fixedly connected to the front of the fixed posts, a spring four fixedly connected to the rear side near the middle of the sliding plate, the other end of the spring four fixedly connected to the front side of the moving plate, a sliding post fixedly connected to the upper front end of the sliding plate, a buckle fixedly connected to the lower front end of the sliding plate, a protective cover slidably connected to the front of the moving plate, multiple circular holes opened inside the protective cover, the circular holes slidably connected to the outer wall of the buckle, an elongated hole one opened at the upper end of the protective cover, a sliding groove slidably connected to the rear end of the moving plate, connecting blocks fixedly connected to the left and right sides of the frame, and multiple fixing mechanisms provided at both ends of the frame for fixing.

[0006] As a further description of the above technical solution:

A spring is fixedly connected between adjacent retaining rings.

[0008] As a further description of the above technical solution:

[0009] The lower end of the outer wall of the connecting cylinder is provided with multiple elongated holes, and the inner wall of the elongated holes is slidably connected to the outer wall of the rotating plate.

[0010] As a further description of the above technical solution:

[0011] A fixing block is fixedly connected to the right side of the connecting block, and the rear end of the fixing block is slidably connected to the front side of the connecting cylinder.

[0012] As a further description of the above technical solution:

[0013] The rear end of the connecting block is fixedly connected to a temple, and the rear end of the temple is fixedly connected to a protective sleeve.

[0014] As a further description of the above technical solution:

[0015] A fixing block two is fixedly connected to the right side of the temple, and the front side of the fixing block two is slidably connected to the outer wall of the connecting cylinder.

[0016] As a further description of the above technical solution:

[0017] The inside of each eyeglass frame is fixedly connected to multiple lenses, and the rear end of each eyeglass frame is fixedly connected to multiple nose bridges.

[0018] As a further description of the above technical solution:

[0019] The moving plate has an elongated hole 2 inside, and the inner wall of the elongated hole 2 is slidably connected to the outer wall of the sliding plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the overall width needs to be adjusted, first press the sliding column, which will drive the sliding plate to move backward, and then drive the buckle to move backward. At this time, the spring four will be squeezed, and then the buckle will leave the circular hole of the protective cover. At this time, pull the sliding column to move to both sides, which will drive the sliding plate to move. The sliding plate drives the moving plate to move along the inside of the slide groove, while stretching the spring three, causing the spring three to deform. When the position is adjusted, release the sliding column.

[0022] 2. In this utility model, during installation, the piston rod is pressed down, which will cause the piston head to squeeze the first spring. At the same time, the rotating plates on both sides are squeezed. Then, the connecting cylinder is placed inside the second fixing block and the first fixing block. Then, the piston rod is released. Under the elastic force of the first spring, the piston rod rebounds, and the rotating plates unfold. At this time, the second fixing block and the first fixing block are fixed. When disassembly is required, the retaining ring is pressed. At this time, the second spring is compressed to provide space for the rotating plates to retract, so that the connecting cylinder can be taken out for replacement of the temple. This realizes the function of quickly replacing the temple when it is damaged. Attached Figure Description

Under the elastic force of the spring 1 202, the piston rod 205 rebounds, and the rotating plate 204 unfolds. At this time, the fixing block 2 19 and fixing block 1 18 are fixed. The same principle applies when disassembly is required. Press the retaining ring 206. At this time, the spring 2 207 is compressed to provide space for the retraction of the rotating plate 204, so that the connecting cylinder 201 can be taken out for replacement of the temple 20. This realizes the function of quickly replacing the temple 20 when it is damaged.
