If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] Reference Figure 1 In the embodiment of the first aspect of the utility model, an axial locking structure includes a frame 100 and an adjustment seat 110. The frame 100 is provided with a clamping arm 106. It can be understood that the clamping arm 106 is used to hang on the ear to achieve a wearable function. The adjustment seat 110 is rotatably connected to the frame 100. It can be understood that the adjustment seat 110 is used to fix the lens 103. Two adjustment seats 110 are provided on the frame 100. Further, the frame 100 is provided with a moving seat 101, and the moving seat 101 can move on the frame 100 to adjust the distance between the two lenses 103 to adapt to the eye distance of the wearer. Further, the frame 100 is provided with a first knob 102 that can adjust the position of the moving seat 101. It can be understood that the first knob 102 is connected to the moving seat 101 through a screw transmission pair, that is, when the first knob 102 is rotated, the moving seat 101 moves linearly along the width direction of the frame 100.

[0036] It is understandable that the adjustment seat 110 is rotatably connected to the moving seat 101 to achieve the adjustment of the angle of the lens 103 by the adjustment seat 110, thereby adjusting the axial position of the lens 103. Further, the moving seat 101 is provided with a second knob 116 that can adjust the rotation angle of the adjustment seat 110, and the rotation angle of the lens 103 is adjusted by the second knob 116. It is understandable that the second knob 116 and the adjustment seat 110 are connected by a gear meshing, and when the second knob 116 rotates, it can drive the adjustment seat 110 to rotate, thereby achieving angle adjustment.

[0037] Further, refer to Figure 7 A plurality of scales 105 are provided on the movable seat 101, and the plurality of scales 105 are distributed on the circumferential outer side of the adjustment seat 110. A mark 121 is provided on the side wall of the adjustment seat 110. The mark 121 can be set as a triangle mark or an arrow mark pointing to the scale 105. When the adjustment seat 110 rotates, the axial angle value of the lens 103 can be observed.

[0038] Reference Figure 1 and Figure 2 A fixed block is provided on the side wall of the adjustment seat 110. At least two fixed blocks are arranged around the rotation axis 124 of the adjustment seat 110, that is, the fixed block is arranged on the end surface of the adjustment seat 110 away from the movable seat 101, and the fixed blocks are arranged along the circumferential direction. At the same time, a fixed assembly is provided on any one of the fixed blocks, and the fixed assembly includes a connecting rod 112 rotatably connected to the fixed block, and a limiting groove 113 is provided at the end of the connecting rod 112. Furthermore, the lens 103 has a holding portion 104, which is arranged on the radial outer periphery of the lens 103 and extends outward for a certain length in the radial direction of the lens 103. When the lens 103 is inserted into the adjustment seat 110, the radial outer wall of the lens 103 abuts against the fixed block, and the holding portion 104 is located in the limiting groove 113. It can be understood that the holding portion 104 is restricted by the limiting groove 113 and cannot move, thereby preventing the lens 103 from rotating on the adjustment seat 110, preventing the lens 103 from being accidentally touched during the fitting process and causing axial deviation, avoiding repeated operations, and improving the fitting efficiency.

[0039] Reference Figure 2 The fixing assembly further includes a connecting seat 111, which is arranged on the fixing block, and one end of the connecting rod 112 away from the limiting groove 113 is hinged to the connecting seat 111, so that the connecting rod 112 can be turned over, so that when the connecting rod 112 is turned over and away from the moving seat 101, the lens 103 can be disassembled and assembled. Figure 5 and Figure 6 The connection seat 111 has a connection groove 122, the connection rod 112 rotates in the connection groove 122, and a damping member 123 is provided between the inner side wall of the connection groove 122 and the outer wall of the connection rod 112. Specifically, a rotating shaft 124 penetrating the connection rod 112 is provided in the connection groove 122, the connection rod 112 rotates around the rotating shaft 124, and the damping member 123 is provided at both ends of the rotating shaft 124, so that the damping member 123 simultaneously abuts against the inner wall of the connection groove 122 and the side walls at both ends of the connection rod 112, thereby generating rotation damping of the connection rod 112, preventing the connection rod 112 from rotating randomly, and making the connection rod 112 stable when fixing the lens 103. It can be understood that the damping member 123 can be made of flexible materials such as silicone, rubber or polyurethane, which is easy to increase the rotation damping.

[0040] Reference Figure 3 , the connecting groove 122 has a first wall surface 114, the connecting rod 112 has a second wall surface 115, and when the limiting groove 113 is buckled with the grip portion 104, the first wall surface 114 abuts against the second wall surface 115, thereby limiting the rotation angle of the connecting rod 112. It can be understood that when the lens 103 is installed, after the limiting groove 113 in the connecting rod 112 is buckled with the grip portion 104, the first wall surface 114 abuts against the second wall surface 115, which can prevent the connecting rod 112 from directly hitting the lens 103 or the frame 100.

[0041] Reference Figure 4 The fixing block is provided with an inserting groove 120, which is recessed on one side of the fixing block close to the rotation center of the adjusting seat 110. It can be understood that when the lens 103 is installed, the inserting grooves 120 on the two fixing blocks are simultaneously in contact with the radial outer wall of the lens 103 to achieve the positioning of the lens 103. Along the direction of the rotation axis 124 of the adjusting seat 110, at least three inserting grooves 120 are arranged in parallel, and at least three lenses 103 can be installed. Because multiple lenses 103 are often required to be used in combination when fitting glasses, providing multiple inserting grooves 120 can improve the flexibility of use.

[0042] Further, the fixing block includes a first fixing block 117 and a second fixing block 118, the first fixing block 117 is provided with a fixing assembly, and the second fixing block 118 is provided with a pressing piece 119, when the lens 103 is inserted into the insertion groove 120, the pressing piece 119 presses against the radial outer wall of the lens 103. It can be understood that the pressing piece 119 is installed on the side of the second fixing block 118 that is away from the rotation center of the adjustment seat 110, and the pressing piece 119 has a certain elasticity. When the lens 103 is installed, the insertion groove 120 on the first fixing block 117 and the second fixing block 118 simultaneously abuts against the radial outer wall of the lens 103, at which time the pressing piece 119 presses against the radial outer wall of the lens 103 and makes the lens 103 press against the first fixing block 117 and the second fixing block 118, so as to realize the fixed installation of the lens 103. It can be understood that the pressing piece 119 can be made of elastic plastic material or stainless steel material to realize elastic pressing contact with the lens 103.
