Description

Technical Field

[0001] The utility model belongs to the technical field of glasses accessories and relates to a glasses hinge. Background Art

[0002] Existing glasses include a frame and lenses. The frame is provided with glasses feet, which are connected to the frame through a hinge structure so that the glasses feet can swing relative to the frame to meet the use requirements of opening and folding the glasses for storage.

[0003] The hinge of glasses is generally composed of a front hinge and a slingshot box connected by a slingshot core assembly. The slingshot core assembly includes a slingshot core, a sleeve and a spring. The slingshot core has a slingshot core head rotatably connected to the front hinge, a slingshot core rod for mounting the spring, and a slingshot core neck connecting the slingshot core head and the slingshot core rod. The sleeve is mounted on the slingshot core neck, one end of the spring is in contact with the sleeve, and the other end is fixed to the end of the slingshot core rod. The sleeve is installed in the slingshot box and fixedly connected to the slingshot box, and the slingshot core can slide in the sleeve as the front hinge rotates.

[0004] However, in the existing eyeglass hinges, in order to facilitate the installation and sliding of the slingshot core assembly, there is often a certain gap between the slingshot core and the inner wall of the slingshot box. In actual use, the slingshot core, the front hinge connected to the slingshot core and other components will swing relative to the slingshot box. In particular, when the legs of the glasses are folded, the position between the front hinge and the slingshot core is perpendicular to the direction of the force of the spring, and there is a lack of a structure to tighten the front hinge and the slingshot core, which makes the structure of the entire eyeglass hinge unstable. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose a spectacles hinge, thereby solving the problem of poor structural stability of the existing spectacles hinge.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A spectacles hinge, comprising a slingshot box, a hinge seat, a spring and an elastic core made of metal material, wherein the slingshot box is in a long strip shape and has a concave mounting hole at one end, the inner end of the elastic core is inserted into the mounting hole, the outer end of the elastic core is connected to the hinge seat through a connecting piece, the spring is sleeved on the outer side of the elastic core and the elastic core can move into the mounting hole under the elastic force of the spring, a positioning hole is provided through the side of the slingshot box at the end of the mounting hole, and the hinge seat can swing to the desired position. The positioning port is characterized in that the elastic movement includes a main body and an elastic part, both of which are in the shape of an elongated strip. The elastic part is located on the side of the outer end of the main body facing the positioning port. The side of the elastic part away from the main body is an inclined surface inclined relative to the length direction of the main body, and the distance between the inclined surface and the side wall on the opposite side of the slingshot box gradually decreases from the bottom of the mounting hole to the opening direction. The other side of the elastic part and the main body facing each other respectively abuts against the inner side walls on the opposite sides of the slingshot box under the elastic force of the elastic movement itself.

[0008] In the present eyeglass hinge, when the hinge seat is relative to the mounting hole, the eyeglass leg is in an open state, and the hinge seat is tightened by the elastic force of the spring so that it is tightly against the slingshot box; when the eyeglass leg is folded and stored, the eyeglass leg is manually moved to swing the hinge seat to the positioning port. At this time, the elastic part and the main body distributed in the same direction tighten the hinge seat under the elastic force of the elastic movement itself, so that the hinge seat is also tightly against the side of the slingshot box, avoiding the shaking of each component during use and folding and storage, and ensuring the structural stability of each component in the entire eyeglass hinge. In addition, the side of the elastic part away from the main body is an inclined surface, which can reduce the contact area between the elastic part and the slingshot box, reduce friction, and facilitate the folding of the eyeglass leg.

[0009] In the above-mentioned eyeglass hinge, the end of the slingshot box with the above-mentioned installation hole opening has a flat abutting surface 1, and the end of the hinge seat facing the slingshot box has a flat abutting surface 2, and the elastic core can drive the hinge seat to abut against the slingshot box under the elastic force of the spring and make the abutting surface 1 and the abutting surface 2 abut against each other. Relying on the abutment of the abutting surface 1 and the abutting surface 2, it is ensured that the hinge part stably abuts against the slingshot box, avoiding shaking and improving stability.

[0010] In the above-mentioned eyeglass hinge, the end of the slingshot box also has a concave groove, and the groove is arranged adjacent to the abutting surface, and the hinge seat has a convex portion that can be inserted into the groove. Relying on the cooperation between the groove and the convex portion, the hinge seat and the slingshot box can be better positioned, avoiding misalignment while also ensuring the stability of the structure.

[0011] In the above-mentioned eyeglass hinge, the side of the slingshot box has a positioning surface around the positioning opening, and when the hinge seat swings to the positioning opening, the second abutment surface can be abutted against the positioning surface. When the hinge seat swings to the positioning opening, the glasses are in a folded storage state, and the hinge seat is stably positioned by the abutment of the positioning surface and the second abutment surface.

[0012] In the above-mentioned eyeglass hinge, the outer end of the elastic movement has a connecting part in the shape of a circular ring, and the connecting part is in the shape of an 8, including a circular ring 1 and a circular ring 2 which are both circular and connected as a whole. The connecting part of the circular ring 1 and the circular ring 2 has a notch 1 that connects the inner hole of the circular ring 1 with the inner hole of the circular ring 2, and the side of the circular ring 2 away from the circular ring 1 has a notch 2, and the connecting part can pass through the notch 2 and the notch 1 in sequence and be mutually connected with the circular ring 1. The end of the hinge seat facing the slingshot box has a concave hole, the circular ring 2 is inserted into the concave hole, and the two opposite side surfaces of the circular ring 2 are respectively adjacent to the two opposite side walls of the concave hole, and a connecting hole is opened through the side wall of the concave hole, and a fastener is inserted in the connecting hole, and the fastener passes through the inner hole of the circular ring 2 and the width of the fastener is greater than the width of the notch 2. The connecting part and the circular ring one are mutually socketed in that the connecting part passes through the inner hole of the circular ring one, and at the same time, the circular ring one passes through the inner hole of the connecting part, and the two are buckled with each other in a vertical direction under the tensioned state; the connecting piece is designed to be 8-shaped to facilitate the insertion and matching of the connecting part, and the concave hole two is slightly larger than the circular ring two, which can prevent the circular ring two from deforming outward in the concave hole, and then cooperate with a fastener with a width greater than the notch two to connect the circular ring two to the hinge seat, and the connection stability is good.

[0013] In the above-mentioned eyeglass hinge, the outer side of the inner end of the elastic movement has a ring-shaped stop edge protruding outward, and the outer side of the elastic movement is also sleeved with a ring-shaped sleeve, the two ends of the spring are respectively abutted against the stop edge and the sleeve, the inner wall of the slingshot box has a protruding limit portion, and the sleeve is abutted against the limit portion under the elastic force of the spring.

[0014] Compared with the prior art, the glasses hinge has the following advantages:

[0015] 1. In the glasses hinge, when the glasses leg is in the open state, the hinge seat and the slingshot box are tightly abutted by the elastic force of the spring. When the glasses leg is in the folded storage state, the hinge seat is tightened by the expansion of the elastic movement made of metal material, so that the hinge seat and the slingshot box are tightly abutted, avoiding the shaking of various components during use, and ensuring the structural stability of various components in the entire glasses hinge.

[0016] 2. The side of the elastic part away from the main body is an inclined surface, which can reduce the contact area between the elastic part and the slingshot box, reduce friction, and facilitate the folding of the glasses legs.

[0017] 3. The connecting piece is designed as an 8-shaped piece with two notches, which can facilitate the insertion and matching of the connecting part and facilitate the connection and fixation of the connecting piece and the hinge seat.

[0018] 4. After the V-shaped elastic movement at the outer end of the glasses hinge is expanded and tightened, the hinge seat can be stably positioned in cooperation with the abutment surface 1, abutment surface 2 and other structures. There is no need to set an additional spring on one side of the hinge seat to ensure the stability of the hinge seat when the glasses legs are folded, thereby simplifying the structure of the hinge seat.

DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1 and Figure 2 As shown, the eyeglass hinge comprises a slingshot box 1, a hinge seat 2, a spring 3 and an elastic movement 4, all of which are made of metal materials. The slingshot box 1 is in a long strip shape and has a concave mounting hole 11 at one end. The inner end of the elastic movement 4 is inserted into the mounting hole 11, and the outer end of the elastic movement 4 is connected to the hinge seat 2 through a connecting piece 5. The spring 3 is sleeved on the outer side of the elastic movement 4 and the elastic movement 4 can move into the mounting hole 11 under the elastic force of the spring 3.

[0024] Specifically, the elastic movement 4 includes a main body 41 and an elastic part 42, both of which are in the shape of a long strip. The elastic part 42 is located on the side of the outer end of the main body 41, and the elastic part 42 and the outer end of the main body 41 form a roughly V-shaped whole. The side of the elastic part 42 away from the main body 41 is an inclined surface 43 inclined relative to the length direction of the main body 41, and the distance between the inclined surface 43 and the side wall of the opposite side of the slingshot box 1 gradually decreases from the bottom of the mounting hole 11 to the opening direction. The other side of the elastic part 42 and the main body 41 facing each other respectively abuts against the inner side walls of the opposite sides of the slingshot box 1 under the elastic force of the elastic movement 4 itself. Here, the elastic movement 4 can be compressed and expanded outward by relying on the maximum distance between the elastic part 42 and the main body 41 being slightly larger than the width of the mounting hole 11 in the slingshot box 1 during actual production.

[0025] In this embodiment, the outer side of the inner end of the elastic core 4 has a ring-shaped stop edge 44 protruding outward, and the outer side of the elastic core 4 is also sleeved with a ring-shaped sleeve 7, and the two ends of the spring 3 respectively abut against the stop edge 44 and the sleeve 7. The slingshot box 1 is squeezed from the outside to the inside, and after the elastic core 4 is installed in the slingshot box 1, a protruding limit portion 16 is formed on the inner wall of the slingshot box 1, and the sleeve 7 abuts against the limit portion 16 under the elastic force of the spring 3.

[0026] The slingshot box 1 has a flat abutting surface 12 at one end of the mounting hole 11, and the hinge seat 2 has a flat abutting surface 21 at one end facing the slingshot box 1. The elastic movement 4 can drive the hinge seat 2 to abut against the slingshot box 1 under the elastic force of the spring 3 and make the abutting surface 12 and the abutting surface 21 abut against each other. The end of the slingshot box 1 also has a concave groove 13, and the groove 13 is arranged adjacent to the abutting surface 12. The hinge seat 2 has a convex portion 22 that can be inserted into the groove 13 on one side of the abutting surface 21. A positioning opening 14 is provided through the side of the slingshot box 1 at the end of the mounting hole 11. The positioning opening 14 is communicated with the end of the mounting hole 11 to form an opening with an L-shaped cross-section. The side of the slingshot box 1 has a flat positioning surface 15 around the positioning opening 14. The hinge seat 2 can swing to the positioning opening 14 and make the abutment surface 21 abut against and position the positioning surface 15. The elastic portion 42 is located on the side of the outer end of the main body 41 facing the positioning opening.

[0027] The outer end of the elastic movement 4 protrudes from the elastic part 42 and has a connecting part 45 in the shape of a ring. The connecting part 5 is in the shape of an 8, and includes a ring 1 51 and a ring 2 52 which are both in the shape of a ring and connected as a whole. The connecting part of the ring 1 51 and the ring 2 52 has a notch 1 53 which connects the inner hole of the ring 1 51 with the inner hole of the ring 2 52. The side of the ring 2 52 away from the ring 1 51 has a notch 2 54, and the connecting part 45 can pass through the notch 2 54 and the notch 1 53 in sequence and be mutually inserted and sleeved with the ring 1 51.

[0028] The hinge seat 2 has a concave hole 23 at one end facing the slingshot box 1. The concave hole 23 is flat and its length and width are only slightly larger than the second circular ring 52, so that after the second circular ring 52 is inserted into the concave hole 23, the two opposite side surfaces of the second circular ring 52 are respectively adjacent to the two opposite side walls of the concave hole 23, that is, the gap is small. A connecting hole is formed through the side wall of the concave hole 23, and a fastener 6 is inserted into the connecting hole. The fastener 6 passes through the inner hole of the second circular ring 52 and the width of the fastener 6 is greater than the width of the second notch 54.

[0029] When the glasses hinge is used, the slingshot box 1 is fixed to the glasses leg, and the hinge seat 2 is fixed to the glasses frame. When the glasses are in the unfolded state, the elastic core 4 moves inward under the elastic force of the spring 3, and the hinge seat 2 is tightened through the connecting piece 5, so that the abutment surface 21 of the hinge seat 2 abuts against the abutment surface 12 of the slingshot box 1, and the convex part 22 is inserted into the groove 13 to achieve stable positioning. When the glasses need to be folded and stored, the glasses leg is folded, the hinge seat 2 remains stationary, and the slingshot box 1 swings relative to the hinge seat 2 so that the position of the hinge seat 2 is opposite to the positioning port 14. The distribution direction of the elastic part 42 and the main body 41 is the same as that of the hinge seat 2 and the slingshot box 1. The elastic core 4 made of metal material tightens the hinge seat 2 under the elastic force of itself after being compressed, so that the abutment surface 21 on the hinge seat 2 abuts against the positioning surface 15 to achieve positioning. At this time, because the sleeve 7 is blocked by the limiting portion 16, the elastic movement 4 is pulled out slightly, and the spring 3 is further compressed to ensure a stable connection state.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
