TECHNICAL FIELD

[0001] The utility model belongs to glasses technical field relates to a glasses leg. BACKGROUND

[0002] In the traditional glasses leg, the foot head and the foot body are directly articulated with screws, the glasses leg can only be opened along the horizontal direction and the maximum opening angle is only 90 DEG, so the glasses using the traditional glasses leg cannot meet the needs of users with different face shapes in actual use. In order to solve this problem, someone has proposed a patent application number 202323149633.2 a multi-directional swing glasses leg silk, it includes main body, hinge connecting piece and connecting piece, the main body includes the first connecting section installed in the end, and the first connecting section is provided with the first through hole, the hinge connecting piece includes the second connecting section installed in the end and the arc connecting section for connecting the glasses frame, and the second connecting section is provided with the second through hole coaxially arranged with the first through hole, the connecting piece is used for the rotary connection between the first connecting section and the second connecting section, wherein the second connecting section is close to the first connecting section one end, and the side surface opposite to the bending direction of the arc connecting section is provided with the arc surface; By setting the hinge connecting portion into the arc surface, abutting after the glasses leg silk is rotated and opened is avoided, so that it can continue to rotate, improve the opening angle, can rotate in the range of 0 DEG-180 DEG.

[0003] However, the above-mentioned multi-directional swing glasses leg silk only increases the maximum opening angle in the horizontal direction from 90 DEG to 180 DEG, and the glasses leg silk along the vertical direction still cannot change the angle, so there is still the problem of insufficient applicability. UTILITY MODEL CONTENTS

[0004] The utility model aims at the above-mentioned problems existing in prior art, proposes a glasses leg, solves the problem of insufficient applicability.

[0005] The utility model can be realized by the following technical schemes:

[0006] The glasses leg comprises a leg body and a leg head arranged in front of the leg body, characterized in that the glasses leg further comprises a connecting piece arranged between the leg head and the leg body, the connecting piece comprises a horizontally arranged connecting piece one and a vertically arranged connecting piece two, the connecting piece one is hinged with the leg head and can swing left and right around the hinge point, the connecting piece two is hinged with the leg body and can swing up and down around the hinge point, the rear end of the leg head is internally provided with a cylindrical guide column one and a spring one acting on the front end of the guide column one, the rear end of the guide column one abuts against the edge of the connecting piece one, the rear end of the guide column one is protrusively provided with a lug one on the left side and the right side respectively, the rear end surface of the guide column one is flush with the rear end surface of the two lugs one, one side edge of the connecting piece one has an anti-swing flat surface, the other side edge of the connecting piece one has a circular arc guide surface one, the circular arc guide surface one is eccentrically arranged relative to the hinge point of the connecting piece one, and the distance between the circular arc guide surface one and the hinge point of the connecting piece one gradually increases from the front end to the rear end of the circular arc guide surface one.

[0007] The connecting piece is connected between the leg head and the leg body, the leg body can swing left and right relative to the leg head through the hinge of the leg head and the connecting piece one, and the leg body can swing up and down relative to the leg head through the hinge of the leg body and the connecting piece two, so that the leg body can swing in all directions relative to the leg head, which improves the applicability. When the leg body swings left and right relative to the leg head to the fully closed state of the glasses leg, the front end surface of the guide column one abuts against the anti-swing flat surface of the connecting piece one, so that the leg body cannot swing relative to the leg head in the direction of opening the glasses leg without external force, that is, the leg body will not shake when the user takes and puts on the glasses with the glasses leg in the fully closed state, which ensures the stability of the glasses leg after being closed. The other side edge of the connecting piece one has a circular arc guide surface one, the circular arc guide surface one is eccentrically arranged relative to the hinge point of the connecting piece one, and the center of the circular arc guide surface one is located behind the hinge point of the connecting piece one, and the distance between the circular arc guide surface one and the hinge point of the connecting piece one gradually increases from the front end to the rear end of the circular arc guide surface one, so that if the leg body is pressed in the left and right directions when the glasses leg is opened by 90°, the rear end of the guide column one can move along the circular arc guide surface one to further open the glasses leg (of course, the spring one will be compressed in this process). After the pressing force disappears, the guide column one can naturally rebound along the circular arc guide surface one to the glasses leg opened by 90° with the reset action of the spring one.

[0008] If the foot body swings relative to the foot head to the position that the rear end surface of the guide post one exceeds the circular arc guiding surface one in the direction of opening the glasses foot, the foot body cannot be smoothly returned along the circular arc guiding surface one under the elastic force of the spring one because the rear end surface of the guide post one does not form effective contact with the circular arc guiding surface one. Therefore, the lug one is protruded on the left and right sides of the rear end of the guide post one, and the rear end surface of the lug one is flush with the rear end surface of the guide post one, so that the effective acting area is increased. Even if the rear end surface of the guide post one exceeds the circular arc guiding surface one, the lug one can form contact with the circular arc guiding surface one to ensure that the foot body is smoothly returned under the elastic force of the spring one. That is, the guide post one with the lug one can swing the foot body relative to the foot head to a larger angle in the direction of opening the glasses foot than the guide post one without the lug one.

[0009] In the above glasses foot, the rear end of the foot head is provided with the mounting hole one, and the guide post one and the spring one are located in the mounting hole one. The rear end of the foot head is protruded with two hinged lugs one, and the two hinged lugs one are oppositely arranged and connected by the connecting piece one through the pin one. The outer diameter of the guide post one matches the hole diameter of the mounting hole one. The two lugs one are located between the two hinged lugs one and abut against the two hinged lugs one at the same time.

[0010] Because the guide post one is cylindrical, the mounting hole one is also a circular hole, and the circumferential position of the guide post one is not positioned after being inserted into the mounting hole one. By arranging the two lugs one between the two hinged lugs one and abutting against the two hinged lugs one at the same time, the circumferential position of the guide post one is positioned so that it cannot be deflected, and the positions of the two lugs one are always on the left and right sides.

[0011] In the above glasses foot, the front end of the foot body is internally provided with the guide post two in a cylindrical shape and the spring two acting on the rear end of the guide post two. The guide post two abuts against the edge of the connecting piece two. The rear end of the connecting piece two has an abutting plane. The two side edges of the connecting piece two are respectively connected with the circular arc guiding surface two between the abutting plane. The two circular arc guiding surfaces two are concentrically arranged and eccentrically arranged relative to the hinge point of the connecting piece two.

[0012] In the case that the glasses leg is opened by 90° and the user does not wear the glasses, the front end of the guide column II abuts against the abutting plane of the connecting piece II under the elastic force of the spring II, so as to ensure that the glasses leg can be naturally kept stable and is not easy to shake in the up-down direction. Since the two side edges of the connecting piece II are respectively connected with the upper and lower arc guide surfaces II, and the two arc guide surfaces II are concentrically arranged and are eccentrically arranged relative to the hinge point of the connecting piece II, if the leg body is pressed upward, the front end of the guide column II can move along the upper arc guide surface II to form an upward swing (of course, the spring II will be compressed in this process), and if the leg body is pressed downward, the front end of the guide column II can move along the lower arc guide surface II to form a downward swing (of course, the spring II will be compressed in this process). After the upward or downward pressing force disappears, the guide column II can naturally spring back to the initial state along the corresponding arc guide surface II with the resetting action of the spring II.

[0013] In the glasses leg, the upper and lower sides of the front end of the guide column II are respectively provided with the lugs II, and the front end surface of the lug II is flush with the front end surface of the guide column II.

[0014] For the guide column II in the cylindrical shape, if the leg body swings upward or downward to the position where the front end surface of the guide column II exceeds the arc guide surface II, the leg body cannot be smoothly reset along the arc guide surface II under the elastic force of the spring II because the front end surface of the guide column II does not form effective contact with the arc guide surface II. Therefore, the upper and lower sides of the front end of the guide column II are respectively provided with the lugs II, and the front end surface of the lug II is flush with the front end surface of the guide column II, so as to increase the effective action area. Even in the case that the front end surface of the guide column II exceeds the arc guide surface II, the lug II can form contact with the arc guide surface II to ensure that the leg body is smoothly reset under the elastic force of the spring II.

[0015] That is, the guide column II provided with the lugs II can swing the leg body at a larger angle upward or downward relative to the leg head than the guide column II without the lugs II.

[0016] In the glasses leg, the front end of the leg body is provided with the mounting hole II, the guide column II and the spring II are located in the mounting hole II, the front end of the leg body is provided with two hinge lugs II, the two hinge lugs II are oppositely arranged, the connecting piece II is hingedly connected between the two hinge lugs II through the pin II, the outer diameter of the guide column II is matched with the hole diameter of the mounting hole II, the two lugs II are located between the two hinge lugs II, and the two lugs II are simultaneously abutted against the two hinge lugs II.

[0017] Because the guide column two is cylindrical, the mounting hole two is also a round hole, and the circumferential position of the guide column two is not positioned after being inserted into the mounting hole two. By setting the two lugs two to be located between the two hinged ears two and the two lugs two are simultaneously abutted with the two hinged ears two, the circumferential position of the guide column two can be positioned so as not to be deflected, and the positions of the two lugs two are always on the upper and lower sides.

[0018] Compared with the prior art, the spectacle foot has the following advantages:

[0019] 1. By setting the connecting piece between the foot head and the foot body, the foot body can swing relative to the foot head in the left-right direction by the hinge between the foot head and the connecting piece one, and the foot body can swing relative to the foot head in the vertical direction by the hinge between the foot body and the connecting piece two, so that the foot body can swing in various directions relative to the foot head, thereby improving the applicability.

[0020] 2. By setting the anti-swing plane on one side of the connecting piece one, when the foot body swings relative to the foot head in the left-right direction to the completely folded state of the spectacle foot, the front end face of the guide column one is abutted with the anti-swing plane of the connecting piece one, so that the foot body does not shake when the user takes and puts on the spectacle in the completely folded state of the spectacle foot, thereby ensuring the stability of the spectacle foot after folding.

DETAILED DESCRIPTION

[0027] The utility model discloses the specific embodiment below and further describes the technical scheme of the utility model with the drawings, but the utility model is not limited to these embodiments.

[0028] As shown in Figure 1 and Figure 2 , a glasses leg includes a leg body 1, a leg head 2 arranged in front of the leg body 1, and a connecting piece 3 arranged between the leg body 1 and the leg head 2. The connecting piece 3 includes a horizontally arranged connecting piece one 3a and a vertically arranged connecting piece two 3b. The connecting piece one 3a is perpendicular to the connecting piece two 3b and the two are integrally connected. The connecting piece one 3a is hinged to the leg head 2 and can swing left and right around the hinge point. The connecting piece two 3b is hinged to the leg body 1 and can swing up and down around the hinge point.

[0029] Further, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a cylindrical guide column one 4 is arranged in the rear end of the leg head 2, and a spring one 5 acts on the front end of the guide column one 4. The rear end of the guide column one 4 abuts against the edge of the connecting piece one 3a. The left and right sides of the rear end of the guide column one 4 are respectively provided with lugs one 4a. The rear end surface of the guide column one 4 is flush with the rear end surfaces of the two lugs one 4a. One side edge of the connecting piece one 3a has an anti-swing flat surface 3a1, and the other side edge of the connecting piece one 3a has a circular arc guide surface one 3a2. The circular arc guide surface one 3a2 is eccentrically arranged relative to the hinge point of the connecting piece one 3a, and the center of the circular arc guide surface one 3a2 is located behind the hinge point of the connecting piece one 3a. The distance between the circular arc guide surface one 3a2 and the hinge point of the connecting piece one 3a gradually increases from the front end to the rear end of the circular arc guide surface one 3a2. Specifically, the rear end of the leg head 2 is provided with a mounting hole one 2a, and the guide column one 4 and the spring one 5 are located in the mounting hole one 2a. The rear end of the leg head 2 is provided with two hinged lugs one 2b, which are arranged opposite to each other. The connecting piece one 3a is hinged between the two hinged lugs one 2b by a pin one 6. The outer diameter of the guide column one 4 matches the hole diameter of the mounting hole one 2a. The two hinged lugs one 2b are distributed vertically, i.e., one of the two hinged lugs one 2b is located below the other. The two lugs one 4a are located between the two hinged lugs one 2b and abut against the two hinged lugs one 2b at the same time. The front end of the connecting piece one 3a has a rearward recess one 3a3.

[0030] Further, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the front end of the foot body 1 is internally provided with a cylindrical guide column two 7 and a spring two 8 acting on the rear end of the guide column two 7. The guide column two 7 abuts against the edge of the connecting piece two 3b, the rear end of the connecting piece two 3b is provided with an abutting plane 3b1, the center of the abutting plane 3b1 is provided with a front recess two 3b3, and the two sides of the connecting piece two 3b are respectively connected with two arc guide surfaces two 3b2 between the two sides and the abutting plane 3b1. The front end of the guide column two 7 is provided with two lugs two 7a on the upper side and the lower side, and the front end surface of the lugs two 7a is flush with the front side surface of the guide column two 7. The front end of the foot body 1 is provided with a mounting hole two 1a, the guide column two 7 and the spring two 8 are located in the mounting hole two 1a, and the front end of the foot body 1 is provided with two hinge ears two 1b, the two hinge ears two 1b are oppositely arranged, the connecting piece two 3b is hingedly connected between the two hinge ears two 1b through a pin two 9, the outer diameter of the guide column two 7 matches the hole diameter of the mounting hole two 1a, and the two lugs two 7a are located between the two hinge ears two 1b and abut against the two hinge ears two 1b.

[0031] The connecting piece 3 is connected between the foot head 2 and the foot body 1, the foot body 1 can swing relative to the foot head 2 in the left-right direction through the hinge of the connecting piece one 3a in the foot head 2 and the connecting piece 3, and the foot body 1 can swing relative to the foot head 2 in the vertical direction through the hinge of the foot body 1 and the connecting piece two 3b, so that the foot body 1 can swing in various directions relative to the foot head 2, which greatly improves the applicability. When the foot body 1 swings relative to the foot head 2 in the left-right direction to the state that the glasses foot is completely closed, the front end surface of the guide column one 4 abuts against the anti-swing plane 3a1 of the connecting piece one 3a, so that the foot body 1 will not swing relative to the foot head 2 in the direction of opening the glasses foot without being subjected to external force, that is, the foot body 1 will not shake when the user takes and puts on the glasses with the glasses foot in the completely closed state, which ensures the stability of the glasses foot after closing. When the user opens the glasses foot 90° from the closed state, the rear end of the guide column one 4 will abut against the front end of the connecting piece one 3a, because the front end of the connecting piece one 3a is provided with a rear recess one 3a3, so that the glasses foot can naturally remain stable at this position without shaking. At the same time, when the glasses foot is opened 90° and the user does not wear the glasses, the front end of the guide column two 7 abuts against the abutting plane 3b1 of the connecting piece two 3b under the elastic force of the spring two 8, which is also to ensure that the glasses foot can naturally remain stable in this state without shaking in the up-down direction.

[0032] The other side of the connecting piece 3a has a circular arc guiding surface 3a2 which is eccentrically arranged relative to the hinge point of the connecting piece 3a and the center of the circular arc guiding surface 3a2 is located behind the hinge point of the connecting piece 3a. The distance between the circular arc guiding surface 3a2 and the hinge point of the connecting piece 3a gradually increases from the front end to the rear end of the circular arc guiding surface 3a2, which makes the glasses leg further open (of course the spring 5 will be compressed in this process) if the leg body 1 is pressed in the left-right direction when the glasses leg is opened by 90°. After the pressing force disappears, the guide column 4 cooperates with the restoring action of the spring 5 to naturally rebound along the circular arc guiding surface 3a2 to the position where the glasses leg is opened by 90°. For the cylindrical guide column 4, if the leg body 1 swings relative to the leg head 2 to the position where the rear end surface of the guide column 4 exceeds the circular arc guiding surface 3a2 in the direction of opening the glasses leg, the leg body 1 cannot smoothly return along the circular arc guiding surface 3a2 under the elastic force of the spring 5 because the rear end surface of the guide column 4 does not form effective contact with the circular arc guiding surface 3a2. Therefore, lugs 4a are protrudingly arranged on the left and right sides of the rear end of the guide column 4, and the rear end surface of the lug 4a is flush with the rear end surface of the guide column 4, which increases the effective action area. Even if the rear end surface of the guide column 4 itself exceeds the circular arc guiding surface 3a2, the lug 4a can still form contact with the circular arc guiding surface 3a2 to ensure that the leg body 1 smoothly returns under the elastic force of the spring 5. That is, the guide column 4 provided with the lug 4a can swing the leg body 1 relative to the leg head 2 to a larger angle in the direction of opening the glasses leg than the guide column 4 without the lug 4a.

[0033] Similarly, since the two side edges of the second connecting piece 3b are connected with the two arc guiding surfaces 3b2 respectively between the two side edges and the abutting plane 3b1, and the two arc guiding surfaces 3b2 are concentrically arranged and eccentrically arranged relative to the hinge point of the second connecting piece 3b, this makes the eyeglasses leg can swing upward by the front end of the second guide column 7 moving along the upper arc guiding surface 3b2 if the leg body 1 is pressed upward when the eyeglasses leg is opened by 90° (of course, the second spring 8 will be compressed in this process), and can swing downward by the front end of the second guide column 7 moving along the lower arc guiding surface 3b2 if the leg body 1 is pressed downward (of course, the second spring 8 will be compressed in this process). After the upward or downward pressing force disappears, the second guide column 7 can naturally rebound to the initial state along the corresponding arc guiding surface 3b2 with the resetting action of the second spring 8. For the cylindrical second guide column 7, if the leg body 1 swings upward or downward to the position where the front end surface of the second guide column 7 exceeds the arc guiding surface 3b2, the leg body 1 cannot smoothly return along the arc guiding surface 3b2 under the elastic force of the second spring 8 because the front end surface of the second guide column 7 does not form effective contact with the arc guiding surface 3b2. Therefore, the lug 7a is protrudingly arranged on the upper side and the lower side of the front end of the second guide column 7, and the front end surface of the lug 7a is flush with the front end surface of the second guide column 7, so as to increase the effective action area, that is, even if the front end surface of the second guide column 7 itself exceeds the arc guiding surface 3b2, the lug 7a can still form contact with the arc guiding surface 3b2 to ensure that the leg body 1 can smoothly return under the elastic force of the second spring 8. That is, the second guide column 7 provided with the lug 7a can make the leg body 1 swing upward or downward relative to the leg head 2 by a larger angle than the case without the lug 7a.
