In addition, a first blocking position 203 is arranged on the first sliding side arm 202 of the first sliding part 2, a sliding limit stroke slot 403 correspondingly matched with the first blocking position 203 is arranged on the side wall of the connecting frame 401 of the second sliding part 4, and the first blocking position 203 and the sliding limit stroke slot 403 are used for limiting the relative sliding stroke of the first sliding part 2 and the second sliding part 4. In this embodiment, the sliding limit stroke slot is a segment of stroke slot, and the first detent is a step position provided on the first sliding side arm, and is just located in the sliding limit stroke slot, and moves inside the sliding limit stroke slot along with the action of external force.

As a further preferable scheme, the outer front side 106 of the contact side wall of the connecting block 102 is provided with a limiting groove 107, the inner contact wall surface 115 of the connecting block 102 is also provided with a limiting groove 108, the front end outer side 406 of the second sliding member 4 is provided with a positioning protrusion 405, and the positioning protrusion 405 is correspondingly clamped into the limiting groove 107 and the limiting groove 108 along the rotation direction of the second sliding member 4.

Utilize multidirectional hinge structure, realize the multidirectional rotation of mirror leg.

In the structure of the present application, the assembly structure of the first slider 2, the second slider 4 and the connecting block 102 realizes that the steering component formed by the first slider 2 and the second slider 4 can rotate around the connecting block 102 in multiple directions (360 degrees), mainly by using the square through hole 103 arranged inside the connecting block 102, the front end of the first slider 2 is inserted into the square through hole 103, so that a structure of a loop is formed between the first slider 2 and the connecting block 102, the first slider 2 can rotate relative to the connecting block in different directions and angles, so that the contact side wall of the connecting block forms a function similar to a rotating shaft, and provides 360-degree rotation for the first slider 2, and more specifically, the rotation towards four side directions of the contact side wall 104 of the connecting block 102. The 360-degree rotation of the first sliding part drives the corresponding rotation of the second sliding part 4 connected with the first sliding part, thereby realizing the integral rotation.

The following further describes the specific operating conditions.

As shown in fig. 1, the initial state is a non-rotational structural state, the steering assembly formed by the connecting member 1, the first sliding member 2 and the second sliding member 4 is kept in a linear state, the spring is in a compressed state, two opposite-direction abutting forces are formed on the second sliding member 4 and the first sliding member 2, so that the first sliding member 2 is tightly attached to the inner front side 105 of the contact side wall 104 of the connecting member 1, and the spring also applies an opposite acting force to the second sliding member 4, so that the second sliding member 4 is pressed towards the contact side wall 104.

When the second slider 4 is pressed toward the connecting block 102, the positioning projections 405 on the second slider 4 and the surfaces on which the positioning projections 405 are located are pressed toward the stopper grooves 107 provided on the outer front side 106 of the contact side wall 104. Therefore, the integral structure of the first sliding piece 2 and the second sliding piece 4 and the connecting piece 1 is compact and stable and is not loosened.

At this time, the state is an initial state, and is reflected on the glasses, that is, the state in which the temples are opened.

As shown in fig. 8 and 9, the steering assembly formed by the first slider 2 and the second slider 4 is now in a fully open state, i.e. rotated 90 degrees relative to the link 1. Since the first attachment bracket 101 is attached to the eyeglass frame, the attachment 1 remains stationary. At this point, a force is applied to rotate the entire steering assembly toward the inner contact wall surface 115 of the connector block 102.

In the rotating process, the outer side surface 406 of the front end of the second sliding member 4 is touched by the inner corner 110 of the contact side wall at the front end of the connecting block 102, and the distance between the second sliding member and the connecting block 102 changes due to the change of the rotating angle, so that the first sliding member 2 is relatively moved under the connection limitation of the second sliding member 4, and is pulled out from the second sliding member 4.

During 90-degree rotation, the front side surface 406 of the second sliding element 4 is restricted to horizontal sliding due to the corresponding V-shaped concave positions (i.e., the limiting grooves) formed on the outer front side surface 106 and the inner contact wall surface 115 of the connecting block 102, and the second sliding element can smoothly transit from the outer front side surface 106 of the connecting block 102 to the inner contact wall surface 115 through complete rotation due to the clearance during rotation.

The steering assembly is arranged to rotate 90 degrees, so that the steering assembly can rotate 90 degrees smoothly. That is, the temple is completely stored in the glasses.

As shown in fig. 10, this is the downward open position (with reference to the orientation of the drawing, it may also be defined as upward or other orientation when the orientation of the drawing is changed). The link 1 is also held relatively stationary while the steering assembly is turned down.

When the steering assembly is rotated upward or downward, the top corner 111 and the bottom corner 112 of the contact sidewall of the connecting block 102 and the outer side surface 406 of the front end of the second sliding member 4 are rotated by a rotation angle, so that the distance between the connecting block and the steering assembly is changed, and the first sliding member 4 is pulled out from the second sliding member 2.

The upper and lower sides of the outer front side of the front end of the connecting block 102 are clearance spaces 109 acting on the first slider 2 to be movable upward and downward.

When the first sliding member 2 rotates up and down, it slides in the sliding limit stroke slot 403 of the second sliding member 4, and the two ends of the sliding limit stroke slot 403 are provided with limit blocks 408, so that when the first block 203 of the first sliding member slides to contact the limit block 408 of the second sliding member, it is prevented from sliding again. Meanwhile, when the contact sidewall top corner 111 or the contact sidewall bottom corner 112 of the connector 1 is rotated to contact the positioning protrusion 405 of the outer lateral surface of the front end of the second slider 4, the re-rotation is prevented.

The effect of above two settings is that the restriction is whole upwards and all down in a small angle within range rotation, and this angle is less than 90 degrees.

As shown in fig. 11, the outward opening state is formed, and the outward opening angular direction is the opposite side of the fully opening direction, i.e., the rear side of the connecting block 102.

When the force is applied by the outward rotation:

the connecting element 1 is held stationary.

When the front end of the first sliding member 2 is engaged with the front end of the connecting block 102, the first sliding cavities 204 in the first sliding member 2 are engaged with each other when they are fastened to the contact side wall 104 and the inner front side 105 of the connecting block 102, and act as a rotating shaft when they are rotated.

When the whole steering assembly rotates towards the rear side of the connecting block, the outer corner 113 of the contact side wall of the connecting block 102 touches the outer side surface 406 of the front end of the second sliding part 4, and the distance between the steering assembly and the connecting block changes due to the change of the rotation angle, so that the first sliding part 2 is pulled out from the second sliding part 4.

When the second sliding member 4 rotates outward, the front outer side 406 of the second sliding member 4 can rotate smoothly because the outer front side 106 of the connecting block 102 has the clearance 109 formed by the concave position.

When the first sliding member 2 rotates to the position where its upper side edge 7 contacts the inner inclined concave positions 114 at the top end and the bottom end of the connecting block, the first sliding member 2 is prevented from rotating outwards again, which acts to limit the rotation angle of the whole rotating assembly to be less than 90 degrees.

Of course, in addition to the above examples, the total can be rotated in four directions of forward, backward, left and right, and different directional manipulations of the temples can be realized.

Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements, and the like can be made in the technical solutions of the foregoing embodiments or in some of the technical features of the foregoing embodiments, but those modifications, equivalents, improvements, and the like are all within the spirit and principle of the present invention.
