Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
As shown in fig. 1 to 5, the large-frame polarized sunglasses according to the present invention includes a frame 1 and lenses 2; the glasses frame 1 comprises a glasses ring 11, a nose bridge 12, a pile head 13, a nose support 14, a hinge 15 and glasses legs 16, wherein the nose bridge 12 comprises a first rod 121, a second rod 122 and a box body 123, the first rod 121 and the second rod 122 are positioned at two ends of the nose bridge 12 and are horizontally staggered, the box body 123 is positioned in the middle of the nose bridge 12, a cylindrical roller 124 is movably installed in the box body 123, a fixed shaft 125 is connected in the roller 124 in a sliding manner, the fixed shaft 125 penetrates through the top of the box body 123, the horizontal section of the middle part of the fixed shaft 125 is square, the horizontal section of the upper part of the fixed shaft is circular, and the horizontal section of the lower part of the fixed shaft is star-shaped; a star-shaped clamping groove 126 is formed in the bottom of the box body 123, opposite to the lower portion of the fixed shaft 125, and the first rod 121 and the second rod 122 penetrate through the side wall of the box body 123 and are always in contact with the surface of the roller 124; two tail ends of the nose bridge 12 are fixedly connected with two mirror rings 11 respectively, a nose support 14 is arranged at one end of each mirror ring 11 opposite to the nose bridge 12, a pile head 13 is fixedly arranged at one end of each mirror ring 11 far away from the nose bridge 12, a hinge 15 is fixedly connected to each pile head 13, and a mirror leg 16 is hinged to each hinge 15; the lens 2 is fixed in the lens ring 11.
When the glasses frame is in work, when the distance between the two glasses legs 16 and the glasses rings 11 needs to be increased, the fixing shaft 125 penetrating through the top of the box body 123 is pulled, the fixing shaft 125 is separated from the star-shaped clamping groove 126 and can rotate, at the moment, only the two glasses rings 11 need to be pulled transversely by hands, the first rod 121 and the second rod 122 move mutually, so that the nose bridge 12 is extended, the distance between the two glasses legs 16 and the glasses rings 11 is increased, the nose bridge 12 can be extended to a certain degree, and the nose bridge 12 is prevented from being excessively extended to separate the two glasses rings 11; because the first rod 121 and the second rod 122 are both contacted with the roller 124, and the first rod 121 and the second rod 122 are horizontally arranged in a staggered manner and have elasticity, the first rod 121 and the second rod 122 move together under the friction action of the roller 124, and the moving distances are the same, so that the mirror rings 11 can be translated simultaneously, and the translating distances are the same, so that the two mirror rings 11 are still symmetrical by the central line of the distance between the two mirror rings 11 after being translated, and the condition that the positions of the mirror rings 11 before eyes are different after the mirror rings 11 are adjusted is reduced; when the distance between the two temples 16 and the lens rings 11 is required to be reduced, only the two lens rings 11 are required to be pushed transversely by hands, and the nose bridge 12 is contracted at the moment, so that the distance between the two temples 16 and the lens rings 11 is reduced; the distance between the two glasses legs 16 and the glasses ring 11 can be freely adjusted by the adjusting mode, so that the requirements of different people are met, and the glasses are more attached to the face; since the first rod 121 and the second rod 122 are thin and have poor stability, when adjustment is not needed, the fixing shaft 125 is pressed down to be clamped in the clamping groove 126, so that the fixing shaft 125 cannot rotate, the roller 124 cannot rotate, the mirror ring 11 cannot easily move, and the stability is improved; because the horizontal cross section of the bottom of the fixed shaft 125 is star-shaped, the fixed shaft 125 cannot be clamped into the clamping groove 126 at any time, and therefore the horizontal cross section of the star-shaped fixed shaft 125 and the star-shaped clamping groove 126 is small, and the fixed shaft 125 can be rotated into the clamping groove 126 within the error allowable range.
In one embodiment of the present invention, the inner surface of the side wall of the box 123 is smooth, the surfaces of the first rod 121 and the second rod 122 facing the inner surface of the side wall of the box 123 are smooth, the surface of the roller 124 is rough, and the surfaces of the first rod 121 and the second rod 122 contacting the surface of the roller 124 are rough.
When the device works, the inner surface of the side wall of the box body 123 and the surface of the first rod 121 and the second rod 122 facing the inner surface of the side wall of the box body 123 are smooth, the friction coefficient of the inner surface of the side wall of the box body 123 is reduced, and the friction coefficient of the side surface of the first rod 121 and the side surface of the second rod 122 facing the inner surface of the side wall of the box body 123 is also reduced, so that the friction force between the side wall of the box body 123 and the first rod 121 and the second rod 122 is reduced, and the situation that the first rod 121 and the second rod 122 cannot move due to overlarge friction force between the side wall of the box body 123 and the surface of the first rod 121 and the second rod 122 is avoided; the arrangement of the rough surface of the roller 124 and the rough surface of the first rod 121 and the second rod 122 contacting with the surface of the roller 124 increases the friction coefficient of the surface of the roller 124 and the friction coefficient of the surface of the first rod 121 and the second rod 122 contacting with the surface of the roller 124, thereby increasing the friction force between the surface of the roller 124 and the surface of the first rod 121 and the second rod 122; the condition that the surface of the roller 124 and the surface of the first rod 121 and the second rod 122 mutually slide is reduced.
In one embodiment of the present invention, the inner surfaces of the side walls of the box 123 facing the first rod 121 and the second rod 122 are curved and are bent toward the inside of the box 123.
When the friction force increasing device works, the inner surface of the side wall of the box body 123 which is bent inwards enables the first rod 121 and the second rod 122 to be extruded when passing through, the extrusion enables the positive pressure of the first rod 121 and the second rod 122 and the roller 124 to be increased, the positive pressure is increased to enable the friction force to be increased, the friction coefficient of the inner surface of the side wall of the box body 123 and the side surface of the first rod 121 and the second rod 122 which are in contact with the inner surface of the side wall of the box body 123 is smaller, the friction coefficient of the surface of the roller 124 and the side surface of the first rod 121 and the side surface of the second rod 122 which is in contact with the surface of the roller 124 is larger, the friction force increasing ratio of the side surface of the first rod 121 and the second rod 122 to the surface of the roller 124 is larger than the friction force increasing ratio of the inner surface of the side wall of the box body 123, and therefore the first rod 121 and the second rod 122 can drive the roller 124 to rotate more easily.
In an embodiment of the present invention, a central portion of a side surface of the roller 124 is an arc-shaped protrusion and is in close contact with the first rod 121 and the second rod 122.
During operation, the central portion of the side surface of the roller 124 is an arc-shaped protrusion, so that on one hand, the contact area between the first rod 121 and the second rod 122 and the roller 124 is increased, on the other hand, the positive pressure between the first rod 121 and the second rod 122 and the roller 124 is increased, and as the surface of the roller 124 and the surface of one side of the first rod 121 and the second rod 122 in contact with the roller 124 are rough, the friction force between the roller 124 and the first rod 121 and the second rod 122 is further increased, and the possibility of slippage between the first rod 121 and the second rod 122 and the roller 124 is reduced.
In one embodiment of the present invention, a star-shaped block 127 is disposed on the top end of the fixed shaft 125, a star-shaped groove 128 is disposed on the top of the box 123, and the end of the star-shaped block 127 is exposed out of the top of the box 123.
When the endoscope ring is in work, under the condition of normal wearing, the fixing shaft 125 is clamped in the star-shaped clamping groove 126 at the bottom of the box body 123, the stability of the endoscope ring 11 is improved, the star-shaped block 127 on the fixing shaft 125 is clamped in the star-shaped groove 128, the stability of the endoscope ring 11 is further improved, when the fixing shaft 125 needs to be pulled out for adjustment, the end part of the designed star-shaped block 127 is exposed out of the top of the box body 123 and is matched with the star-shaped block 127 to enable the pulling-out to be simpler, the stress point is increased through the star-shaped block 127, when the degree of tightness is adjusted in an overlarge mode of pushing and pulling the two endoscope rings 11, the star-shaped block 127 can be twisted for fine adjustment, and the demands of people are further met.
In one embodiment of the present invention, the star block 127, the star groove 128, the star cross section at the bottom of the fixing shaft 125, and the star slot 126 at the bottom of the box 123 have the same number of corners, and when the star block 127 is inserted into the star groove 128, the fixing shaft 125 is also inserted into the star slot 126, and the corners of all the stars correspond to each other.
During operation, as the star-shaped clamping grooves 126 are formed in the bottom of the box body 123 and the cross section of the bottom of the fixing shaft 125 is in a star shape, the situation that the fixing shaft 125 cannot be accurately clamped into the clamping grooves 126 is inevitable when the clamping degree is increased, so that when the star-shaped block 127 is clamped into the star-shaped groove 128, the fixing shaft 125 is also just clamped into the star-shaped clamping grooves 126, and the sharp corners of all the stars correspond one to one at the time; because the star-shaped block 127 is coaxially connected with the fixed shaft 125, the rotation angle of the star-shaped block 127 is the same as that of the fixed shaft 125, and further, after the mirror ring 11 is adjusted, if the star-shaped block 127 can be clamped into the star-shaped groove 128, the fixed shaft 125 can be clamped into the star-shaped groove 126, so that whether the fixed shaft 125 can be clamped into the star-shaped groove 126 can be visualized, and the situation of probing back and forth is avoided.
The specific working process is as follows:
when the distance between the two temples 16 and the mirror rings 11 needs to be increased, the fixing shaft 125 penetrating through the top of the box body 123 is pulled to separate the fixing shaft 125 from the star-shaped clamping groove 126 and rotate, at this time, only the two mirror rings 11 need to be pulled transversely by hand, and the first rod 121 and the second rod 122 move mutually, so that the nose bridge 12 is extended, the distance between the two temples 16 and the mirror rings 11 is increased, and the nose bridge 12 can only be extended to a certain degree, so that the nose bridge 12 is prevented from being excessively extended to separate the two mirror rings 11; since the first rod 121 and the second rod 122 are both in contact with the roller 124, the first rod 121 and the second rod 122 are horizontally staggered with each other, the inner surface of the side wall of the box body 123 and the first rod 121 and the second rod 122 contacted with the inner surface are smooth, the surface of the roller 124 and the surface of the first rod 121 and the second rod 122 contacted with the roller are rough, the central part of the side wall of the box body 123 is an arc-shaped bulge and the central part of the side surface of the roller 124 is also an arc-shaped bulge, the friction between the roller 124 and the first rod 121 and the second rod 122 is increased through the two ways, the first rod 121 and the second rod 122 move together under the friction of the roller 124, and the moving distance is the same, so that the lens rings 11 can be translated simultaneously, and the translation distances are the same, so that after the two lens rings 11 are translated, the central line of the distance between the two mirror rings 11 is still symmetrical, so that the situation that the positions of the mirror rings 11 in front of eyes are different after the mirror rings 11 are adjusted is reduced; when the distance between the two temples 16 and the lens rings 11 is required to be reduced, only the two lens rings 11 are required to be pushed transversely by hands, and the nose bridge 12 is contracted at the moment, so that the distance between the two temples 16 and the lens rings 11 is reduced; the distance between the two glasses legs 16 and the glasses ring 11 can be freely adjusted by the adjusting mode, the requirements of different people are met, the glasses are enabled to be more attached to the face, when the adjustment is not needed, the fixing shaft 125 is pressed down, the fixing shaft 125 is clamped in the clamping groove 126, the fixing shaft 125 cannot rotate, the roller 124 cannot rotate, the glasses ring 11 cannot easily move, and the stability is improved; in addition, since the star-shaped slot 126 is formed in the bottom of the box 123 and the cross section of the bottom of the fixing shaft 125 is in a star shape, the situation that the fixing shaft 125 cannot be accurately clamped into the slot 126 is inevitable while the clamping degree is increased, so that when the star-shaped block 127 is clamped into the star-shaped slot 128, the fixing shaft 125 is also just clamped into the star-shaped slot 126, and the sharp corners of all the stars correspond one to one at the time; because the star-shaped block 127 is coaxially connected with the fixed shaft 125, the rotation angle of the star-shaped block 127 is the same as that of the fixed shaft 125, and further, after the mirror ring 11 is adjusted, if the star-shaped block 127 can be clamped into the star-shaped groove 128, the fixed shaft 125 can be clamped into the star-shaped groove 126, so that whether the fixed shaft 125 can be clamped into the star-shaped groove 126 can be visualized, and the situation of probing back and forth is avoided.
