Description

Technical Field

[0001] This invention relates to the field of eyeglass lens hanging technology, and in particular to a lens hanging device for eyeglasses sun protection and its usage method. Background Technology

[0002] In real life, more and more people are using glasses for reasons such as nearsightedness, presbyopia, and sun protection. Sometimes they need to use glasses for nearsightedness or presbyopia, and sometimes they need to use glasses with other functions. Therefore, structures that attach other functional lenses to the front of the original glasses have appeared on the market, such as sun-protective lenses.

[0003] In existing technologies, most sunshade devices can only be hung on the frame and cannot be rotated. Since the sunshade cannot be clearly viewed when looking at dark places, the operator needs to remove the sunshade device when they need to view dark places briefly, which is quite inconvenient. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a lens hanging device for eyeglasses and its usage method, so as to solve the above problems.

[0005] In view of this, the present invention provides a hanging device for sun protection of eyeglasses, comprising:

[0006] Two mounting frames are provided, each with a mounting hole and a mounting groove at the top of each mounting frame, the mounting groove extending to the end wall of the mounting frame;

[0007] Two sunshades are installed in the mounting holes respectively;

[0008] The connecting rod is connected at both ends between the two mounting frames;

[0009] Four rotating mechanisms, with fixed ends respectively located on both sides of the inner wall of the two mounting slots, and rotating ends extending out of the mounting slots;

[0010] Four supporting structures are respectively connected to the rotating end of the rotating mechanism;

[0011] And snap-fit ​​structures, respectively set on the support structure and the mounting frame;

[0012] The four supporting structures are respectively secured on both sides of the top of the two mirror frames. The mounting frame rotates on the supporting structures via a rotating mechanism. The locking structure is used to fix the mounting frame after it rotates.

[0013] By adopting the above technical solution, the connecting rod enables the two mounting frames to be connected, the mounting frames enable the installation of the sunshade, the sunshade provides shade for the operator, the mounting slot enables the installation of the rotating mechanism, the support structure provides overall support, the rotating mechanism allows the mounting frame to rotate around the support structure, and the snap-fit ​​structure prevents the mounting frame from falling off when rotated to a certain angle, thus allowing the operator to temporarily stop using the sunshade without having to remove it entirely.

[0014] In the above technical solution, the further rotating mechanism includes:

[0015] Threaded holes are provided on the wall of the mounting groove;

[0016] The mounting post has a first external thread on one side of its outer wall that is threaded to a threaded hole, and a receiving groove on the other end.

[0017] The limiting structure is detachably connected to the end of the mounting post that is away from the threaded hole.

[0018] The damper has a fixed end installed at the bottom of the receiving groove, and a rotating end extending towards the opening of the receiving groove.

[0019] The installation structure has one end connected to the rotating end of the damper, and the other end passes through the limiting structure and connects to the support structure.

[0020] The receiving groove has a limiting groove on its wall, and the damper has a limiting block on its outer side wall that is inserted into the limiting groove. When the mounting frame rotates, the mounting column rotates on the mounting structure through the damper. The limiting structure is used to make the mounting column and the damper rotate stably on the mounting structure, and the damper is used to make the mounting frame descend slowly.

[0021] In this technical solution, the threaded hole allows the first external thread to be threaded, enabling the mounting rod to be disassembled and fixed. The receiving groove allows the damper to be installed. The mounting structure allows the mounting column to rotate on the mounting structure via the damper. The limiting structure ensures stable rotation of the mounting structure and the damper. The cooperation between the limiting groove and the limiting block allows the mounting column to drive the damper to rotate. The damper allows the mounting frame to descend slowly, preventing damage caused by excessive impact when the mounting frame rotates back.

[0022] In the above technical solution, the further limiting structure includes:

[0023] The limiting ring abuts against the end of the mounting post that is away from the threaded hole;

[0024] The connecting tube has one end of its inner wall fixedly connected to the outer wall of the limiting ring, and the other end is fitted onto the outer wall of the mounting column.

[0025] The connecting pipe has a second internal thread on its inner wall, and the mounting post has a second external thread that is threadedly connected to the second internal thread.

[0026] In this technical solution, the setting of the limiting ring makes the rotation of the mounting column more stable and can also prevent the mounting structure from separating from the damper. The cooperation of the second internal thread and the second external thread can fix the connecting rod and the limiting ring.

[0027] In the above technical solution, the further installation structure includes:

[0028] The fixed column has a socket on one end wall for the damper's rotating end to be inserted, and the other end passes through the limiting ring and is located outside the limiting ring.

[0029] The insertion slot is located on the side wall of the fixed column opposite to the damper.

[0030] The anti-fall-off component is fitted onto the end of the fixed column that faces away from the damper.

[0031] And the connecting component, one end of which is connected to the support structure, and the other end of which passes through the anti-detachment component and is inserted into the insertion slot;

[0032] The connecting component is used to support the fixed column, the anti-detachment component is used to prevent the connecting component from falling off the fixed column, and the anti-detachment component also prevents the fixed column from separating from the damper.

[0033] In this technical solution, the damper can be connected by the setting of the fixed column and the socket. The setting of the anti-detachment component can prevent the fixed column from separating from the damper and also prevent the connecting component from falling out of the socket. The setting of the connecting component can support the fixed column.

[0034] In the above technical solution, the further anti-fall-off component includes:

[0035] The U-shaped groove is provided at one end and both sides of the fixed column that are away from the damper, and the two ends of the U-shaped groove extend into the receiving groove.

[0036] The U-shaped anti-detachment component is adapted to fit into the U-shaped groove. The horizontal end of the U-shaped anti-detachment component is attached to the bottom of the U-shaped groove, and the two ends extend into the receiving groove through the U-shaped groove but are not attached to the bottom of the U-shaped groove.

[0037] Two locking blocks are respectively set on both sides of the U-shaped anti-detachment component, and the locking blocks abut against the end of the limiting ring facing the receiving groove through the U-shaped anti-detachment component;

[0038] And a snap-fit ​​body, which is fitted onto the end of the fixing post away from the receiving groove, and the snap-fit ​​body has two insertion holes circumferentially provided on the outer side wall;

[0039] The two insertion holes are interconnected, and one insertion hole is larger than the other. The connecting component is inserted into the plug slot through the larger insertion hole. When the snap-fit ​​body rotates, the connecting component rotates into and fits into the smaller insertion hole.

[0040] In this technical solution, firstly, both ends of the U-shaped anti-detachment component are pressed into the U-shaped groove, so that the locking blocks are not blocked by the limiting ring. Then, the U-shaped anti-detachment component is pushed forward until the two locking blocks enter the limiting ring. At this time, the U-shaped anti-detachment component is released, and the U-shaped anti-detachment component returns to its original state. The two locking blocks are locked on the limiting ring. At this time, the connecting component is inserted into the insertion slot through the large insertion hole. When the locking body rotates, the connecting component rotates into and fits into the small insertion hole. At this time, the connecting component cannot move out of the locking body.

[0041] In the above technical solution, the further connection component includes:

[0042] Insert the insertion rod into the insertion slot;

[0043] The limiting plate is inserted into the socket and located at the opening of the insertion slot;

[0044] And a moving rod, one end of which is connected to the opposite end of the insertion slot of the limiting plate, and the other end is connected to the support structure through the insertion hole;

[0045] The end of the moving rod away from the insertion slot is provided with a third external thread that is threadedly connected to the support structure.

[0046] In this technical solution, the insertion rod can be inserted into the insertion slot, and the limiting plate can be moved into the larger insertion hole but cannot be moved out of the smaller insertion hole, thus restricting the insertion rod. The moving rod can be connected to the supporting structure, and the moving rod can be disassembled.

[0047] In the above technical solution, the further supporting structure includes:

[0048] The U-shaped support block is inserted into the top of the frame at the notch.

[0049] An elastic pad is placed on the inner wall of the U-shaped support block;

[0050] The outer wall of the U-shaped support block is provided with a third internal thread for the third external thread connection.

[0051] In this technical solution, the U-shaped support block can be inserted into the top of the frame, the elastic pad can make the U-shaped support block fit against the frame, and the third internal thread can fix the moving rod.

[0052] In the above technical solution, the further snap-fit ​​structure includes:

[0053] Four insertion slots are located at the top of the U-shaped support block and connected to the side of the U-shaped support block facing the mounting frame;

[0054] Four support rods are respectively set on both sides of the top of the mounting frame;

[0055] And several elastic abutment blocks are respectively set on both sides of the inner wall of the rotating groove;

[0056] When the mounting frame rotates, the support rod rotates into the slot, and the elastic abutment block is used to prevent the support rod from easily falling out after it enters the slot.

[0057] In this technical solution, when the mounting frame is rotated, the support rod is also rotated and moved, and the support rod will slowly rotate into the slot. When the mounting frame rotates at a certain angle, the support rod abuts against the elastic abutment block and is located below the elastic abutment block. At this time, the support rod is abutted by the elastic abutment block and cannot rotate automatically.

[0058] The above technical solution further includes the following steps:

[0059] S1: First, connect the first external thread to the threaded hole. At this time, the mounting post is installed. Then, install the limit block along the limit groove. At this time, the damper is installed. Then, insert the socket of the fixed post into the rotating end of the damper. Put the limit ring into the fixed post. Then, connect the second external thread to the second internal thread. At this time, the limit ring abuts against the port of the mounting post and is placed on the outer wall of the fixed post. Then, press both ends of the U-shaped anti-detachment part into the U-shaped groove and push it into the receiving groove. Then, release the U-shaped anti-detachment part. At this time, the horizontal end of the U-shaped anti-detachment part abuts against the U-shaped groove and the locking block abuts against the end wall of the limit ring. Then, insert the locking body into the fixed post and make the large insertion hole and the insertion groove face each other. Then, pass the insertion rod and the limit plate through the large insertion hole and insert them into the insertion groove. Finally, rotate the locking body to move the moving rod into the small insertion hole.

[0060] S2: Then connect the third internal thread of the U-shaped support block to the third external thread, at which point the U-shaped support block is installed;

[0061] S3: When needed, place the four U-shaped support blocks on the top of the two frames to install the entire assembly. When the sunshade is not needed temporarily, simply rotate the mounting frame upwards to rotate the support rod into the rotating groove and lock the support rod under the elastic abutment block.

[0062] In this technical solution, setting S1 enables the overall assembly, setting S2 completes the installation of the support structure, and setting S3 allows the overall system to be temporarily or permanently unused. Attached Figure Description

[0083] And snap-fit ​​structures are respectively set on the support structure and the mounting frame 1;

[0084] The four support structures are respectively snapped onto the two sides of the top of the two mirror frames. The mounting frame 1 rotates on the support structure through a rotating mechanism. The snap-fit ​​structure is used to fix the mounting frame 1 after it rotates.

[0085] The connecting rod 5 connects the two mounting frames 1, allowing the sunshade 4 to be installed. The sunshade 4 provides shade for the operator. The mounting slot 3 allows the rotating mechanism to be installed. The support structure provides overall support.

When the snap-fit ​​body 22 rotates, the connecting component rotates into and fits into the smaller insertion hole 23.

[0116] First, press both ends of the U-shaped anti-detachment component 20 into the U-shaped groove 19 so that the locking block 21 is not blocked by the limiting ring 12. Then push the U-shaped anti-detachment component 20 forward until the two locking blocks 21 enter the limiting ring 12. At this time, release the U-shaped anti-detachment component 20 and the U-shaped anti-detachment component 20 returns to its original state. The two locking blocks 21 are locked on the limiting ring 12. At this time, the connecting component is inserted into the insertion slot 18 through the large insertion hole 23. When the locking body 22 rotates, the connecting component rotates into and fits into the small insertion hole 23. At this time, the connecting component cannot move out of the locking body 22.

[0129] The U-shaped support block 28 can be inserted into the top of the frame. The elastic pad 29 allows the U-shaped support block 28 to abut and fit. The third internal thread allows the moving rod 26 to be fixed.

[0130] Example 8:

[0131] In this embodiment, in addition to the structural features of the aforementioned embodiments, the further snap-fit ​​structure includes:

[0132] Four insertion slots 30 are provided at the top of the U-shaped support block 28 and connected to the side of the U-shaped support block 28 facing the mounting frame 1;

[0133] Four support rods 31 are respectively set on both sides of the top of the mounting frame 1;

[0134] And several elastic abutment blocks 32 are respectively disposed on both sides of the inner wall of the rotating groove;

[0135] When the mounting frame 1 rotates, the support rod 31 rotates into the insertion groove 30, and the elastic abutment block 32 is used to prevent the support rod 31 from easily falling out after it abuts into the groove.

[0136] When the mounting frame 1 is rotated, the support rod 31 is also rotated and moved. The support rod 31 will slowly rotate into the slot 30. When the mounting frame 1 rotates at a certain angle, the support rod 31 abuts against the elastic abutment block 32 and is located below the elastic abutment block 32. At this time, the support rod 31 is abutted by the elastic abutment block 32 and cannot rotate automatically.

[0137] Example 9:

[0138] In this embodiment, in addition to the structural features of the foregoing embodiments, the following steps are further included:

[0139] S1: First, thread the first external thread 7 into the threaded hole. At this point, the mounting post 6 is installed. Then, install the limiting block 11 along the limiting groove 10. At this point, the damper 9 is installed. Next, insert the socket 17 of the fixing post 16 into the rotating end of the damper 9. Slide the limiting ring 12 onto the fixing post 16. Then, thread the second external thread 15 into the second internal thread 14. At this point, the limiting ring 12 abuts against the port of the mounting post 6 and is placed on the outer wall of the fixing post 16. Then, press the two ends of the U-shaped anti-detachment part 20... Press it into the U-shaped groove 19 and push it into the receiving groove 8, then release the U-shaped anti-detachment part 20.
