Description

TECHNICAL FIELD

[0001] The utility model relates to glasses technical field, especially to the outside elastic hinge structure and glasses. BACKGROUND

[0002] At present, the common glasses hinge structure is usually that the top end of the temple is rotatably connected with the end of the head of the frame through a screw, realizing the opening and closing function of the temple. In this structure, the rotation angle of the temple relative to the head is usually 90°, and this angle is a fixed value. When the temple is rotated to be in a straight line with the head, the temple is in a completely unfolded wearing state; when the temple is rotated inward to be perpendicular to the head, the temple is in a folded storage state.

[0003] However, in daily actual use, since the user cannot accurately rotate the temple to the ideal angle of 90° when unfolding it, there is often a situation of excessive unfolding, causing serious pressing between the temple and the head. This pressing not only increases the frictional resistance during use, but also easily causes the screw to loosen or the hinge to wear during repeated use, thereby causing problems such as loosening, deformation, and even falling off of the temple. The above structure has great limitations in service life, wearing comfort, and maintenance cost, and needs to be improved to improve the durability and user experience of the overall structure. SUMMARY

[0004] Therefore, it is necessary to provide an outside elastic hinge structure and glasses in which the temple can be flipped outward to form elastic buffering, effectively avoiding hard pressing between the temple and the head, to solve the problem of easy serious pressing between the temple and the head, causing loosening, deformation, and even falling off of the temple.

[0005] An outside elastic hinge structure, comprising:

[0006] a head, which is hollow inside and has an opening at one end communicating with the inside;

[0007] a flexible accessory, which is movably arranged in the head;

[0008] a plug-in part, comprising a protruding arm and a main hinge, the protruding arm is inserted into the head through the opening, and the protruding arm is fixedly abutted against the inside top wall of the head under the abutment of the flexible accessory; and

[0009] a temple, which has a secondary hinge at the end, the secondary hinge is rotatably connected with the main hinge, the top of the end of the temple is abutted against the plug-in part, and the bottom of the temple has a rotation space with the plug-in part; when the temple is rotated towards the bottom, it can be folded and stored, when the temple is rotated towards the top, the protruding arm abuts against the flexible accessory, causing the flexible accessory to move downward.

[0010] The convex arm of the plug-in part can be inserted into the temple, and abuts against the elastic part. The end of the temple is rotatably connected with the main hinge of the plug-in part through the auxiliary hinge. When the temple is turned downward, the temple and the temple can form a 90° angle, and the temple is in a folding storage state. When the temple is turned upward, the convex arm can press the elastic part downward, and the elastic part moves downward to form an elastic buffer. When the user wears the glasses and turns the temple outward, the temple and the temple are prevented from being pressed hard, and the temple is prevented from being loose, deformed or even falling off. In addition, the plug-in connection is adopted in the external elastic hinge structure, and the temple has a detachable function when being installed, so that the replacement of the damaged temple is more convenient.

[0011] In one of the embodiments, the elastic part comprises a clamping core and an elastic member. One end of the clamping core is rotatably connected with the inside of the temple, and the elastic member abuts against the other end of the clamping core and the inside bottom wall of the temple.

[0012] In one of the embodiments, a fixed bolt is further included. The end of the clamping core away from the convex arm is a terminal end, and the fixed bolt passes through the terminal end of the clamping core and the temple.

[0013] In one of the embodiments, the end of the clamping core close to the convex arm is a front end, and a convex column is protruded at the bottom of the front end of the clamping core. The elastic member is a spring and is sleeved on the convex column.

[0014] In one of the embodiments, a column head with an arc-shaped outer surface is protruded at the top of the front end of the clamping core. A plug with an arc-shaped top surface is protruded at the bottom of the top end of the convex arm. The plug is slidable along the column head, and the plug passes over the column head and abuts against the clamping core.

[0015] In one of the embodiments, the column head is spherical.

[0016] In one of the embodiments, the main body of the clamping core is in a strip plate shape, and the convex column is located below the connection between the column head and the main body of the clamping core.

[0017] In one of the embodiments, the plug-in part further comprises a positioning plate vertically arranged. The convex arm and the main hinge are arranged on the opposite two plate surfaces of the positioning plate.

[0018] In one of the embodiments, the convex arm and the main hinge are staggered vertically, and the position of the convex arm is higher than that of the main hinge.

[0019] The utility model also provides a kind of glasses, comprising: glasses frame and the external elastic hinge structure as described above, and the temple is fixed on the opposite sides of the glasses frame. BRIEF DESCRIPTION OF DRAWINGS

Further, the column head 224 can be spherical.

[0036] The main body part of the card core 221 is in the shape of a long strip plate, and the convex column 223 is located below the connection between the column head 224 and the main body of the card core 221, so that when the convex arm 231 presses down the card core 221, the force borne by the elastic member 222 is more stable.

[0037] In an embodiment of the plug-in part 23, a positioning plate 234 is further provided vertically, the convex arm 231 and the main hinge 232 are respectively arranged on the opposite two plate surfaces of the positioning plate 234, and can be arranged staggered up and down, and the convex arm 231 is located above the main hinge 232.
