Description

Technical Field

[0001] The utility model belongs to the technical field of glasses, and relates to a frame rotation mechanism and glasses thereof. Background Art

[0002] Glasses, as a tool for protecting eyes, include spectacle lenses and a spectacle frame for supporting the spectacle lenses. Currently, traditional spectacle frames usually consist of a frame, a nose bridge, nose pads, and temple arms. There are two frames, left and right, which are connected by the nose bridge. There are also two temple arms, left and right, which are respectively hinged to the left and right frames. Traditional glasses cannot adjust the frame during use. For people wearing myopia glasses, when looking at nearby objects, they can see clearly without wearing glasses and can take them off at this time; for people wearing hyperopia glasses, when looking at objects at different distances, they often need to constantly take off and put on glasses to achieve the clearest effect, which brings great trouble to people using glasses. Frequent taking off and putting on not only wastes time but also easily damages the glasses, greatly reducing the service life of the glasses. In addition, in order to adjust the line of sight and avoid the stimulation of strong light to the eyes, many people choose colored glasses to filter and adjust the light to protect eyesight. When there is no need to change the light, they need to take off or replace the glasses, which is very troublesome. In view of this situation, a kind of rotatable glasses appears on the market, such as a kind of rotatable glasses described in Chinese Patent No.: "201220610784.6". The specific structure of this rotatable glasses is as follows: it includes lenses and a frame. A nose pad is installed on the frame. A sleeve is provided on the frame above the two lenses. A connecting rod is provided between the two temple arms. A connecting pipe with the same inner diameter and coaxial with the sleeve is provided on the connecting rod. A pin shaft extends into the central holes of the sleeve and the connecting pipe to connect the sleeve and the connecting pipe. In the above structure, through the cooperation of the pin shaft with the sleeve and the connecting pipe, the rotation of the lenses can be realized. However, the hinge of the pin shaft does not have a limiting or positioning structure. When the lenses rotate upward, the lenses must be held by hand, otherwise the lenses will rotate downward naturally due to gravity. At the same time, when a person wearing glasses makes an upward movement such as jumping, the lenses will naturally turn up, affecting the normal use of people. Summary of the Invention

[0003] The purpose of the utility model is to provide a frame rotation mechanism and glasses thereof, which can prevent the frame body from falling naturally due to gravity when the rotation of the frame body pauses and maintain the state after rotation, aiming at the above problems existing in the prior art.

[0004] The object of the present utility model can be achieved by the following technical solutions: a frame rotating mechanism, including two frame bodies and a connecting seat connecting the two frame bodies, further including a mounting bracket. A separating hole is formed on the connecting seat, and the separating hole forms an elastic piece and a rotating block that can be separated from each other on the connecting seat. The end of the rotating block is an arc-shaped hook portion. A mounting hole is formed in the middle of the mounting bracket. The middle of the mounting bracket is clamped between the rotating block and the elastic piece. The end of the hook portion passes through the mounting hole and hooks the hole wall of the mounting hole. The hook portion, the elastic piece and the frame body can rotate relative to the mounting bracket. During the rotation process, the elastic piece and the hook portion always clamp the mounting bracket.

[0005] In the above-mentioned frame rotating mechanism, the separating hole is in an "n" shape. A protruding portion protrudes upward from the middle of the connecting seat. The top of the separating hole is located inside the protruding portion, and the bottom of the separating hole is located below the protruding portion. Wave-shaped extension holes are connected to both sides of the bottom of the separating hole.

[0006] In the above-mentioned frame rotating mechanism, the two ends of the connecting seat are bent obliquely downward to form bent portions. The bent portions make the side surface of the connecting seat in an isosceles trapezoid shape. The bent portions are connected to the frame body, and the ends of the extension holes extend to the bent portions.

[0007] In the above-mentioned frame rotating mechanism, a limiting groove is further formed in the middle of the mounting bracket. The limiting groove is located below the mounting hole. When the elastic piece rotates, the end of the elastic piece gradually enters the limiting groove.

[0008] In the above-mentioned frame rotating mechanism, the elastic piece and the rotating block are integrally formed on the connecting seat, and the connecting seat is made of an elastic metal material.

[0009] Glasses, including the above-mentioned frame rotating mechanism, further including a nose bracket, a nose pad and two temple arms. The nose pad is installed on the nose bracket. The two temple arms are respectively hinged to both ends of the mounting bracket. The end of the nose bracket is bent to form an insertion block. An insertion hole is formed in the middle of the mounting bracket. The insertion hole is located above the mounting hole. The insertion block is press-fitted into the insertion hole.

[0010] In the above-mentioned glasses, the nose bracket includes two nose pad rods. The end of the nose pad rod is provided with a nose pad mounting block. A nose pad mounting groove is formed on the nose pad mounting block. A nose pad convex block is formed on the nose pad. The width of the nose pad convex block is greater than the width of the nose pad mounting groove. A circle of card slots is formed on the nose pad convex block. The nose pad is made of an elastic material. The nose pad convex block is snapped into the nose pad mounting groove, and the nose pad mounting block is snapped into the card slots.

[0011] In the above-mentioned glasses, insertion limit blocks are further provided on both sides of the insertion block. When the insertion limit blocks come into contact with the side surface of the mounting frame, the insertion block is inserted in place.

[0012] Compared with the prior art, in the frame rotation mechanism and the glasses thereof, the frame body can rotate relative to the mounting frame through the hook portion and the elastic sheet. When it is not desired to have the lens block the eyes, the frame body can be rotated upward; when the lens is in use, the elastic sheet closely adheres to the side surface of the mounting frame to prevent the frame body from naturally flipping up due to upward movements such as jumping by a person; meanwhile, during the rotation process, the elastic sheet and the hook portion always clamp the mounting frame, so that when the frame body pauses rotating, it will not naturally fall due to gravity and remains in the rotated state; the wavy extension holes increase the area of the connecting seat that deforms with the rotation of the elastic sheet and the rotating block, thereby dispersing the deformation force of the elastic sheet and the rotating block, preventing the elastic sheet and the rotating block from breaking from the connecting seat due to excessive deformation force during rotation, and the extension holes ensure the strength of the elastic sheet and the rotating block, making them not easily break; the bent portions at both ends of the connecting seat increase the overall strength of the connecting seat, making it not easily break, and at the same time, the bent portions make the connecting seat in an isosceles trapezoid shape with the middle arched upward. The force for the connecting seat to flip up needs to counteract the force for its middle to arch upward, making the elastic force of the connecting seat better. When rotated downward and reset by a certain angle, the connecting seat can automatically rebound to the use state. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0018] Such as Figures 1-3As shown in the figure, this pair of glasses includes a frame rotation mechanism. The frame rotation mechanism includes two frame bodies 1 and a connecting seat 2 connecting the two frame bodies 1. It also includes two temple arms 3 and a mounting bracket 4 connecting the two temple arms 3. The two temple arms 3 are respectively hinged to both ends of the mounting bracket 4. The middle part of the connecting seat 2 protrudes upward to form a protruding part 21. A "n"-shaped separation hole 22 is formed on the connecting seat 2. The top of the separation hole 22 is located inside the protruding part 21, and the bottom of the separation hole 22 is located below the protruding part 21. The separation hole 22 forms an elastic piece 24 and a rotating block 25 on the connecting seat 2 that can be separated from each other. The end of the rotating block 25 is an arc-shaped hook part 26. A mounting hole 41 is formed in the middle of the mounting bracket 4. The middle part of the mounting bracket 4 is clamped between the rotating block 25 and the elastic piece 24. The end of the hook part 26 passes through the mounting hole 41 and hooks the hole wall of the mounting hole 41, so that the connecting seat 2 is connected to the mounting bracket 4. The hook part 26, the elastic piece 24 and the frame body 1 can rotate relative to the mounting bracket 4.

[0019] When the lens is in use, the frame body 1 is placed downward, and the elastic piece 24 closely adheres to the side surface of the mounting bracket 4 to prevent the frame body 1 from naturally turning up due to upward movements of a person such as jumping. When you don't want the lens to block your eyes, rotate the frame body 1 upward. The hook part 26 rotates in the mounting hole 41, and the elastic piece 24 rotates with the connecting seat 2. The frame body 1 can be turned up at most to an inverted state. During the rotation process, the elastic piece 24 and the hook part 26 always clamp the mounting bracket 4, so that the frame body 1 will not naturally fall due to gravity when the rotation pauses, and is maintained in the rotated state.

[0020] In the above technical solution: Wave-shaped extension holes 23 are connected to both sides of the bottom of the separation hole 22. The extension holes 23 increase the area of the connecting seat 2 that deforms with the rotation of the elastic piece 24 and the rotating block 25, thereby dispersing the deformation force of the elastic piece 24 and the rotating block 25, preventing the elastic piece 24 and the rotating block 25 from breaking off the connecting seat 2 due to excessive deformation force during rotation. The extension holes 23 ensure the strength of the elastic piece 24 and the rotating block 25, making them not easily break.

[0021] In the above technical solution: Both ends of the connecting seat 2 are bent obliquely downward to form bent parts 27. The bent parts 27 make the side surface of the connecting seat 2 an isosceles trapezoid. The bent parts 27 are connected to the frame body 1, and the ends of the extension holes 23 extend to the bent parts 27. The bent parts 27 increase the overall strength of the connecting seat 2, making it not easily break. At the same time, the bent parts 27 make the connecting seat 2 an isosceles trapezoid with the middle part arched upward. The force when the connecting seat 2 turns up needs to counteract the force of its middle part arching upward, making the elastic force of the connecting seat 2 better. When it rotates downward and resets by a certain angle, the connecting seat 2 can automatically rebound to the use state.

[0022] In the above technical solution: A limiting groove 42 is also formed in the middle of the mounting bracket 4. The limiting groove 42 is located below the mounting hole 41. When the elastic piece 24 rotates, the end of the elastic piece 24 gradually enters the limiting groove 42. The limiting groove 42 not only limits and guides the rotation process of the elastic piece 24, but also prevents interference between the mounting bracket 4 and the rotating elastic piece 24.

[0023] In the above technical solution: The elastic piece 24 and the rotating block 25 are integrally formed on the connecting seat 2. The connecting seat 2 is made of an elastic metal material. The spectacle frame body 1 and the connecting seat 2 are also integrally formed.

[0024] In the above technical solution: It further includes a nose support bracket 5 and a nose pad 6. The nose pad 6 is installed on the nose support bracket 5. The end of the nose support bracket 5 is bent to form an insertion block 51. Figure 3 The nose support bracket 5 in is in an unbent state. An insertion hole 43 is formed in the middle of the mounting bracket 4. The insertion hole 43 is located above the mounting hole 41. The insertion block 51 is press-fitted into the insertion hole 43 to complete the detachable installation between the nose support bracket 5 and the mounting bracket 4, facilitating the maintenance and replacement of the nose support bracket 5. Insertion limiting blocks 55 are also provided on both sides of the insertion block 51. When the insertion limiting blocks 55 come into contact with the side surface of the mounting bracket 4, the insertion block 51 is inserted in place.

[0025] In the above technical solution: The nose support bracket 5 includes two nose support rods 52. The end of the nose support rod 52 is formed with a nose pad mounting block 53. A nose pad mounting groove 54 is formed in the nose pad mounting block 53. A nose pad convex block 61 is formed on the nose pad 6. The width of the nose pad convex block 61 is greater than the width of the nose pad mounting groove 54. A circle of card slots 62 is formed on the nose pad convex block 61. The nose pad 6 is made of an elastic material. By squeezing the nose pad convex block 61, the nose pad convex block 61 is snapped into the nose pad mounting groove 54 until the nose pad mounting block 53 is snapped into the card slot 62 to complete the installation of the nose pad 6 and the nose support bracket 5. The nose pad convex block 61 resets to prevent the nose pad 6 from accidentally detaching from the nose support bracket 5. The connection between the nose pad 6 and the nose support bracket 5 is detachable, and no tools are required for installation and disassembly. Just squeeze the nose pad 6 and remove it from the nose pad mounting groove 54, facilitating the replacement of the nose pad 6.

[0026] The frame rotation mechanism and the glasses thereof enable the frame body 1 to rotate relative to the mounting bracket 4 through the hook portion 26 and the elastic piece 24. When it is not desired to have the lens block the eyes, the frame body 1 can be rotated upward; when the lens is in use, the elastic piece 24 closely adheres to the side surface of the mounting bracket 4 to prevent the frame body 1 from naturally turning up due to upward movements such as jumping by the person; meanwhile, during the rotation process, the elastic piece 24 and the hook portion 26 always clamp the mounting bracket 4, so that when the frame body 1 pauses rotating, it will not naturally fall due to gravity and maintains the state after rotation; the wavy extension hole 23 increases the area of the connecting seat 2 that deforms along with the rotation of the elastic piece 24 and the rotating block 25, thereby dispersing the deformation force of the elastic piece 24 and the rotating block 25 and preventing the elastic piece 24 and the rotating block 25 from breaking off the connecting seat 2 due to excessive deformation force during rotation. The extension hole 23 ensures the strength of the elastic piece 24 and the rotating block 25, making them not easily break; the bending portions 27 at both ends of the connecting seat 2 increase the overall strength of the connecting seat 2, making it not easily break. At the same time, the bending portions 27 make the connecting seat 2 in an isosceles trapezoid shape with the middle arched upward. The force for the connecting seat 2 to turn up needs to counteract the force for its middle to arch upward, making the elastic force of the connecting seat 2 better. When rotated downward and reset by a certain angle, the connecting seat 2 can automatically rebound to the use state.
