Description

Technical Field

[0001] This application relates to the field of mirrors, and more particularly to an adjustable mirror frame. Background Technology

[0002] A mirror is an object that reflects light. People can see their own reflection in a mirror. When installing a mirror, a mirror frame is needed. The mirror frame is used to support and fix the mirror body and also to beautify the edges.

[0003] For example, the utility model patent with patent publication number CN220859838U discloses a mirror frame, including an outer frame, an mounting base installed on one side of the outer frame, a sliding groove opened on the other side of the outer frame, a slope set on one side of the inner wall of the outer frame, and a card seat fixedly connected to one side of the sliding groove. The card seat is fitted with buckles, and different additional accessories can be replaced at any time according to the user's needs.

[0004] The aforementioned mirror frame is a fixed-size, integrated structure. Due to the wide variety of mirror body sizes, users often need to customize a matching frame when they need to change to a different size mirror body. This not only increases the user's cost but also leads to the original frame being idle and wasted, reducing resource utilization and requiring improvement. Summary of the Invention

[0005] To address the issue that users often need to customize frames when changing to different sizes of eyeglasses, which not only increases user costs but also leads to the waste of existing frames and reduces resource utilization, this application provides an adjustable frame.

[0006] This application provides an adjustable eyeglass frame, which adopts the following technical solution:

[0007] An adjustable eyeglass frame includes an upper frame, a lower frame, and a connecting block. The lower frame includes a main body and an extension rod disposed on the main body. The upper frame slides up and down on the extension rod. The upper frame and the main body are joined to form a mounting groove for inserting the eyeglass. Positioning grooves are provided on both sides of the upper frame. Several positioning grooves are provided on the extension rod. The several positioning grooves are located on both sides of the extension rod and are spaced apart along the sliding direction of the upper frame.

[0008] The connecting block includes a block body, a positioning block one and a positioning block two disposed on the block body, and a clearance groove is provided on the block body for the upper frame and the extension rod to be inserted into. The positioning block one and the positioning block two are located in the clearance groove, with the positioning block one located on both sides of the clearance groove. The positioning groove one is for the positioning block one to be inserted into, and the positioning block two corresponds to the positioning block one. The positioning groove two is for the positioning block two to be inserted into.

[0009] By adopting the above technical solution, the lens body is placed between the upper frame and the main body. Then, the upper frame is moved closer to the main body, so that the lens body is inserted into the mounting groove. Then, positioning block one and positioning groove one are aligned, and positioning block two and corresponding positioning groove two are aligned. The blocks are moved closer to the upper frame, so that the upper frame and extension rod are inserted into the clearance groove. At the same time, positioning block one is inserted into positioning groove one, and positioning block two is inserted into positioning groove two. By positioning block one abutting against the inner wall of positioning groove one, and positioning block two abutting against the inner wall of positioning groove two, the upper frame and lower frame can be connected and positioned. By moving the upper frame and connecting blocks, mounting grooves of different sizes can be formed to accommodate lens bodies of various sizes and specifications. Users can reuse existing frames by adjusting them, reducing frame idleness and waste, improving resource utilization, and reducing the additional costs incurred by users due to frame replacement.

[0010] Optionally, the upper frame is provided with a stud, and an adjusting block is threadedly connected to the stud. The block is provided with a through hole for the stud to pass through, and the adjusting block is used to abut against the side of the block away from the upper frame.

[0011] By adopting the above technical solution, when the upper frame and the extension rod are inserted into the clearance groove, the stud passes through the through hole, and the torsion adjustment block is threadedly connected to the stud, so that the adjustment block abuts against the side of the block away from the upper frame, thus positioning the connecting block. This reduces the possibility of positioning block one and positioning block two disengaging from positioning groove one / positioning groove two under sudden conditions such as vibration, and improves the connection stability between the upper frame and the lower frame.

[0012] Optionally, the connecting block is provided with an elastic abutment block, which is located in the relief groove and between the upper frame and the bottom of the relief groove, and the elastic abutment block abuts against the upper frame.

[0013] By adopting the above technical solution, the upper frame is pressed against the elastic clamping block, and the reaction force of the elastic clamping block makes the block press against the adjusting block, thereby making the threads on the adjusting block and the stud press against each other, preventing loosening between the adjusting block and the stud, and improving the positioning stability of the connecting block.

[0014] Optionally, the ends of both positioning block one and positioning block two near the bottom of the relief groove are connected to the block body.

[0015] By adopting the above technical solution, positioning block one and positioning block two are integrated with the block body, which improves the overall structural strength and bending resistance of the connecting block and ensures the reliability of the connection between the upper and lower frame bodies through the connecting block during long-term use of the frame.

[0016] Optionally, the elastic abutment block includes an annular piece and an elastic piece disposed on the annular piece. The annular piece is disposed in contact with the inner wall of the relief groove, positioning block one and positioning block two. The elastic piece is located on the side of the annular piece close to the upper frame and is inclined inward toward the upper frame.

[0017] By adopting the above technical solution, an annular plate and an elastic plate are set. When the adjusting block is twisted, the adjusting block pushes the block to move closer to the upper frame. At this time, the elastic plate is squeezed by the upper frame and deforms, thereby generating a clamping force on the upper frame. When the elastic clamping block is used for a long time and the elastic plate undergoes elastic fatigue and irreversible deformation, affecting the clamping effect, the elastic clamping block is removed from the relief groove. Then, a new elastic clamping block is placed in the relief groove. The replacement of the elastic clamping block is completed by the annular plate fitting against the inner wall of the relief groove, and the positioning blocks one and two are used to achieve the limit. This gives the connecting block a more durable clamping effect.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By moving the upper frame and connecting block, mounting slots of different sizes can be formed to accommodate various sizes of eyeglasses. Users can reuse existing eyeglasses by adjusting them, reducing idle waste and improving resource utilization. It can also reduce the additional costs incurred by users due to replacing eyeglasses.

[0020] 2. By adjusting the side of the block that abuts against the block away from the upper frame, the connecting block is positioned, which reduces the possibility of positioning block one and positioning block two disengaging from positioning groove one / positioning groove two under sudden conditions such as vibration, and improves the connection stability between the upper frame and the lower frame.

[0021] 3. The upper frame is pressed against the elastic clamping block. The reaction force of the elastic clamping block makes the block press against the adjusting block, which in turn makes the threads on the adjusting block and the stud press against each other, preventing the adjusting block and the stud from loosening and improving the positioning stability of the connecting block.
