Abstract
Description
Technical Field
[0001] The utility model relates to the field of glasses, in particular to a spring hinge. Background Art
[0002] During the traditional use of glasses, when the user takes off the glasses with one hand, the temple that is held will be forced to turn outward, and the conventional folding design of the temple can only fold inward. The outward turning operation will cause the temple to deform and lead to poor subsequent wearing. At the same time, during the removal process, the temple on the side that is not held will be pressed against the head under the pull of the temple that is held, which is not convenient when taking off. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a spring hinge which can facilitate the removal of glasses and avoid deformation of the temples of the glasses due to improper removal operation.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a spring hinge, which is installed between the temples and the frame of the glasses, and includes a rotating block and a fixed block; the rotating block includes a first shell and a first rotating member, and the fixed block includes a second shell, a first rotating member is provided on the first shell, and the first shell is connected to a limiting column at one end close to the second shell, and a plurality of concave limiting surfaces are provided on the circumference of the limiting column, and the second shell is abutted against the circumference of the limiting column; a spring is connected between one end of the first rotating member and the first shell, and the other end is rotatably connected to the second shell.
[0005] Furthermore, the first rotating member is a hook member, the second shell is provided with a ring member, and the hook member is buckled with the ring member.
[0006] Furthermore, the interior of the limiting column is hollow, and the first rotating member extends into the limiting column and is rotatably connected to the second shell.
[0007] Furthermore, a second rotating member is provided on the second shell, and the first rotating member is rotatably connected to the second rotating member; the interior of the limiting column is hollow, the first rotating member extends into the limiting column, and a limiting groove is provided on the limiting column corresponding to the second rotating member, and the second rotating member passes through the limiting groove and is connected to the first rotating member in the limiting column.
[0008] Furthermore, the first rotating member and the spring are both disposed in the first housing.
[0009] Furthermore, a second rotating member rotatably connected to the first rotating member is provided on the second housing, and a spring is connected between the second rotating member and the second housing.
[0010] Furthermore, the first shell and the second shell are both provided with screw locking holes.
[0011] Furthermore, the second housing is a cuboid, and the end face in its length direction abuts against the limiting column.
[0012] The beneficial effects of the present utility model are as follows: The multi-angle rotation between the temple and the frame can be achieved through the rotation design of the first rotating member of the rotating block and the second housing; through the cooperation of the first rotating member, the spring, the first housing and the limiting column, a limiting surface is set at certain specific rotation angles. For example, when the glasses are unfolded for wearing or folded for storage, it can be set that the second housing rotates to cooperate with the limiting surface of the limiting column in this state, and the spring connected to the first rotating member remains in the initial state. At other rotation angles, the second housing rotates to abut against the circumferential surface of the limiting column. Since the circumferential surface of the limiting column protrudes from the limiting surface, the second housing will pull the first rotating member, thereby stretching the spring. In this way, at other rotation angles, the first rotating member can have a tendency to return, so that the rotation angle of the first rotating member and the second housing can return to a specific rotation angle after the external force is removed. Such a design can achieve that the temple connected thereto can rotate relative to the frame at multiple angles and has an automatic return function. When the user removes the glasses with one hand, the multi-angle rotation can be used to avoid excessive pulling and deformation of the traditional temple that can only be folded inward. At the same time, the other temple can automatically turn outward under force, thereby quickly removing the entire pair of glasses; it is also convenient when wearing. At the same time, when the temple turns outward relative to the frame, the temple can have a tendency to clamp the user's head, which can improve the adaptability to different head shapes.

[0019] To describe the technical content, achieved objectives and effects of the present utility model in detail, the following is described in conjunction with the embodiments and with reference to the drawings.
[0020] Please refer to Figures 1 to 4 , a spring hinge, which is installed between the temple and the frame of glasses, and includes a rotating block 1 and a fixed block 2; the rotating block 1 includes a first housing 11 and a first rotating member 12, the fixed block 2 includes a second housing 21, the first rotating member 12 is provided on the first housing 11, a limiting column 13 is connected to one end of the first housing 11 close to the second housing 21, a plurality of concave limiting surfaces 15 are provided on the circumferential surface of the limiting column 13, and the circumferential surface of the second housing 21 abuts against the circumferential surface of the limiting column 13; a spring is connected between one end of the first rotating member 12 and the first housing 11, and the other end is rotatably connected to the second housing 21.
[0021] As can be seen from the above description, the beneficial effects of the present utility model are as follows: The multi-angle rotation between the temple and the frame can be realized through the rotation design of the first rotating member 12 of the rotating block 1 and the second housing 21; through the cooperation of the first rotating member 12, the spring, the first housing 11 and the limiting column 13, the limiting surface 15 is set at certain specific rotation angles, such as when the glasses are unfolded and worn or when the glasses are folded and stored, it can be set that the second housing 21 rotates to cooperate with the limiting surface 15 of the limiting column 13 and the spring connected to the first rotating member 12 remains in the initial state at this state. At other rotation angles, the second housing 21 rotates to abut against the circumferential surface of the limiting column 13. Since the circumferential surface of the limiting column 13 protrudes from the limiting surface 15, the second housing 21 will pull the first rotating member 12 and then the spring is stretched. In this way, at other rotation angles, the first rotating member 12 can have a tendency to return so that the rotation angles of the first rotating member 12 and the second housing 21 after the external force is removed can return to the specific rotation angles. Such a design can realize that the connected temple can rotate relative to the frame at multiple angles and has an automatic return function. When the user removes the glasses with one hand, the multi-angle rotation can be used to avoid excessive pulling and deformation of the traditional temple that can only be folded inward. At the same time, the other temple can automatically turn outwards under force and then quickly remove the whole pair of glasses; it is also convenient when wearing. At the same time, when the temple turns outwards relative to the frame, the temple can have a tendency to clamp the user's head, which can improve the adaptability to different head shapes.
[0022] Further, the first rotating member 12 is a hook member, a ring member is provided on the second housing 21, and the hook member is buckled with the ring member.
[0023] As can be seen from the above description, through the buckling design of the hook member and the ring member, the rotational connection can be quickly realized and there is a large rotational amplitude between the two, which can cover the rotation angles during daily use.
[0024] Further, the limiting column 13 is hollow inside, and the first rotating member 12 extends into the limiting column 13 and is rotatably connected to the second housing 21.
[0025] As can be seen from the above description, through the design of the first rotating member 12 extending into the limiting column 13, the limiting column 13 can be used as a protective member to shield and protect the first rotating member 12 to prevent it from being exposed.
[0026] Further, a second rotating member 22 is provided on the second housing 21, and the first rotating member 12 is rotatably connected to the second rotating member 22; the limiting column 13 is hollow inside, the first rotating member 12 extends into the limiting column 13, and a limiting groove 14 corresponding to the second rotating member 22 is provided on the limiting column 13, and the second rotating member 22 passes through the limiting groove 14 and is connected to the first rotating member 12 inside the limiting column 13.
[0027] As can be seen from the above description, when the first rotating member 12 and the second rotating member 22 cooperate, both are arranged inside the limiting column 13 for hidden protection design. Through the design of the limiting groove 14, the amplitude of the rotation of the first rotating member 12 relative to the second rotating member 22 can be restricted to avoid excessive amplitude and over-stretching, which may cause damage to the spring.
[0028] Further, the first rotating member 12 and the spring are both arranged inside the first housing 11.
[0029] As can be seen from the above description, through the design of the first rotating member 12 and the spring inside the first housing 11, the layout space is optimized, the structure is made more concise, and at the same time, the first rotating member 12 and the spring can be protected.
[0030] Further, a second rotating member 22 rotatably connected to the first rotating member 12 is provided on the second housing 21, and a spring is connected between the second rotating member 22 and the second housing 21.
[0031] As can be seen from the above description, by connecting the second rotating member 22 to the first rotating member 12 and using the spring designed between the second rotating member 22 and the second housing 21 to assist the stretching of the spring between the first housing 11 and the first rotating member 12, the tensile force is shared through the double-spring design to avoid the situation where the single spring has a reduced lifespan after long-term use and loses its elasticity.
[0032] Further, screw locking holes 3 are provided on both the first housing 11 and the second housing 21.
[0033] As can be seen from the above description, through the design of the screw locking holes 3 on the first housing 11 and the second housing 21, the rotating block 1 and the fixed block 2 can be quickly fixed to the temple or the frame.
[0034] Further, the second housing 21 is a cuboid, and the end face in its length direction abuts against the limiting column 13.
[0035] As can be seen from the above description, with the cuboid design of the second housing 21, when its end face abuts against the circumferential surface of the limiting column 13, due to the cylindrical configuration of the limiting column 13, its circumferential surface is tangent to the end face of the cuboid, and the contact surface is small. After being subjected to the spring elastic force, the end face of the cuboid can quickly separate from the circumferential surface of the cylinder and cooperate with the concave limiting surface 15 with a larger contact surface. After the cooperation, the larger contact surface design of the two can also reduce the accidental deviation during use.
[0036] Embodiment 1:
[0037] Application scenario: During the use of traditional glasses, when the user removes the glasses with one hand, the temple being held will be forced to turn outwards. The conventional folding design of the temple can only achieve inward folding, and the outward turning operation will cause the temple to deform and lead to poor subsequent wearing; at the same time, the temple on the unheld side will also be pressed against the head under the pulling of the held temple during the removal process, making it not convenient enough to remove.
[0038] As Figures 1 to 4 shown, the spring hinge of this embodiment is installed between the temple and the frame of the glasses, and includes a rotating block 1 and a fixed block 2. The rotating block 1 includes a first housing 11 and a first rotating member 12, and the fixed block 2 includes a second housing 21 and a second rotating member 22. A screw locking hole 3 is provided on the first housing 11 of the rotating block 1, and the first housing 11 is inserted into the temple and screwed thereto. A screw locking hole 3 is also provided on the second housing 21 of the fixed block 2, and the second housing 21 is inserted into the frame and screwed thereto.
[0039] A first rotating member 12 is provided inside the first housing 11. A limiting column 13 is connected to one end of the first housing 11 close to the second housing 21. A plurality of concave limiting surfaces 15 are provided on the circumferential surface of the limiting column 13. The second housing 21 is a cuboid, and the end face in the length direction of the second housing 21 abuts against the circumferential surface of the limiting column 13; a spring is connected between one end of the first rotating member 12 and the first housing 11, and the first rotating member 12 is a hook member; a second rotating member 22 is provided inside the second housing 21, a spring is provided between the second rotating member 22 and the second housing 21, and the second rotating member 22 is a ring member; the limiting column 13 is hollow, a limiting groove 14 is provided on the limiting column 13 corresponding to the ring member, the hook member extends into the limiting column 13, and the ring member passes through the limiting groove 14 and is buckled with the hook member inside the limiting column 13 to achieve the relative rotation of the two at multiple angles.
[0040] In the design of the position of the limiting surface 15 described above, concave limiting surfaces 15 are provided on both the side of the limiting column 13 opposite to the second housing 21 when the temple is unfolded and the side of the limiting column 13 opposite to the second housing 21 when the temple is folded and stored.
[0041] Under the action of the spring at the first rotating member 12, the peripheral surface of the limiting column 13 on the first housing 11 can always abut against the end surface of the second housing 21. In the unfolded state and the folded state of the temple, the second housing 21 abuts against the limiting surface 15, and the spring is in the initial state at this time; in the process of the conventional horizontal outward or inward folding of the temple described above, since the end surface of the second housing 21 abuts against the peripheral surface of the cylinder of the limiting column 13 itself, which protrudes relative to the concave limiting surface 15, the spring on the first rotating member 12 is stretched. After the external force disappears, under the action of the spring, the first rotating member 12 can be rotated to a position where the second housing 21 abuts against the limiting surface 15. Under more folding at other angles, by pulling the first housing 11, the second housing 21 can be disengaged from abutting against the peripheral surface of the limiting column 13, thereby releasing the rotation restriction of the second housing 21. With the cooperation of the hook member and the ring member, it can rotate at multiple angles. In these states, the spring is also in a stretched state, and after the external force is lost, the elastic force of the spring can also be used to rotate the first rotating member 12 to a position where the second housing 21 abuts against the limiting surface 15.
[0042] In summary, the spring hinge provided by the present utility model can achieve multi-angle rotation between the temple and the frame through the rotation design of the first rotating member of the rotating block and the second housing; through the cooperation of the first rotating member, the spring, the first housing and the limiting column, a limiting surface is set at certain specific rotation angles. For example, when the glasses are unfolded and worn or when the glasses are folded and stored, it can be set that in this state, the second housing rotates to cooperate with the limiting surface of the limiting column and the spring connected to the first rotating member remains in the initial state. At other rotation angles, the second housing rotates to abut against the peripheral surface of the limiting column. Since the peripheral surface of the limiting column protrudes from the limiting surface, the second housing will pull the first rotating member, thereby stretching the spring. In this way, at other rotation angles, the first rotating member can have a tendency to return, so that the rotation angles of the first rotating member and the second housing after the external force is removed can return to the specific rotation angles. Such a design can achieve that the connected temple can rotate relative to the frame at multiple angles and has an automatic return function. When the user removes the glasses with one hand, the multi-angle rotation can be used to avoid excessive pulling and deformation of the conventionally only inwardly foldable temple. At the same time, the other temple can automatically turn outwards under force, thereby quickly removing the entire pair of glasses; it is also convenient to wear. At the same time, when the temple turns outwards relative to the frame, the temple can have a tendency to clamp the user's head, which can improve the adaptability to different head shapes.
[0043] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in the related technical fields, shall be similarly included in the patent protection scope of the present utility model.
