Abstract
Description
Technical Field
[0001] The utility model relates to the field of glasses design, in particular to an inside-outside folding structure of glasses. Background Art
[0002] Glasses are a common optical device, mainly used for correcting eyesight, protecting eyes or as ornaments, etc. Glasses mainly include lenses and frames, and the lenses are fixedly embedded in the frames. And now conventional frames usually include a frame and temple arms, and the temple arms are connected to the frame.
[0003] In order to reduce the occupied space of glasses when not in use and reduce the probability of glasses being damaged due to too large contact area, now there are often protrusions on the frame, grooves are provided in the protrusions, and bumps are provided on the temple arms. The bumps extend into the grooves and the protrusions and bumps are connected by a pin shaft to realize the hinged connection between the temple arms and the frame.
[0004] Under the above connection method, usually the folding feel of the inside-folded temple arms only depends on the damping provided by the pin shaft, the feel is poor or even there is no feel at all, and the temple arms are ineffective in maintaining the folded state and are prone to become the open state. When folding outwards, the frame usually has a limiting part to limit the opening amplitude of the temple arms folding outwards to meet the wearing needs of users. However, in this way, there is basically no fault tolerance space for the temple arms to continue folding outwards. Once the temple arms are folded outwards excessively due to improper external force, the temple arms may be deformed and difficult to reset, and it cannot effectively return to the required opening angle and can only be repaired or replaced, and the reliability is poor. Summary of the Utility Model
[0005] The purpose of the utility model is to provide an inside-outside folding structure of glasses, which can solve one or more of the above problems.
[0006] According to one aspect of the utility model, there is provided an inside-outside folding structure of glasses, including a frame, temple arms, a fixed seat, a rotating member, a pin shaft structure and a leaf spring.
[0007] The frame is provided with a cross beam, the fixed seat is connected to the cross beam, the rotating member is connected to the temple arms, the rotating member is rotatably installed on the fixed seat through the pin shaft structure, and the leaf spring is installed on the fixed seat.
[0008] The rotating member is provided with a kit, the kit is arranged outside the leaf spring, the inner wall of the kit is provided with a first protrusion and a second protrusion, the leaf spring is provided with a bump, and the bump abuts against the inner wall of the kit and is arranged between the first protrusion and the second protrusion.
[0009] The beneficial effects of the present utility model are as follows: In the present utility model, the rotating member can rotate on the fixed seat, enabling the temple and the frame to rotate relative to each other, so as to realize the inward folding or outward folding of the temple. And because a leaf spring is also provided, the outward open state of the temple can be maintained by relying on the elastic force of the leaf spring under normal conditions, which is convenient for users to wear. Corresponding convex blocks, a first protrusion and a second protrusion are provided. Thus, when the temple is folded inward, the convex block can contact the first convex block, causing the leaf spring to be compressed, so as to provide a feel of inward folding until the convex block crosses the first protrusion. At this time, since the convex block of the leaf spring is not subjected to force and cannot pass through the first protrusion in the reverse direction, the folded state of the temple can be effectively maintained. When the temple is excessively folded outward to a certain extent under an external force, the convex block can contact the second protrusion to compress the leaf spring, so as to buffer the external force. When the external force stops being applied and the outward folding amplitude does not cause the convex block to exceed the second protrusion, the leaf spring can rely on its elasticity to restore the temple to its normal open position. Therefore, in the present utility model, there is a good feel when the temple is folded inward, and the folded state of the temple can be effectively maintained after folding. At the same time, there is a certain tolerance space for further outward folding after the temple is folded outward, which buffers the external force and can still restore to the normal open state after a certain external force ends, with strong reliability.
[0010] In some embodiments, the pin shaft structure includes a pin shaft and a snap ring. The fixed seat is provided with a pin shaft seat, and the rotating member is provided with a top plate connected to the top of the kit. One end of the pin shaft passes through the pin shaft seat and the top plate in sequence and is connected to the snap ring.
[0011] In some embodiments, a groove is provided on the side of the pin shaft seat, the leaf spring is provided with an arc portion, the convex block is arranged on the arc portion, the arc portion is sleeved on the pin shaft seat, one end of the arc portion is provided with a folded foot, and the folded foot is embedded in the groove. This enables the end of the arc portion with the folded foot to be effectively fixed on the pin shaft seat.
[0012] In some embodiments, a straight portion is provided at the other end of the arc portion, and the fixed seat is provided with a first connecting plate. The straight portion can abut against the first connecting plate. This enables the other end of the arc portion to be fixed at the first connecting plate by relying on the elastic force of the leaf spring.
[0013] In some embodiments, the cross beam is provided with a first accommodating cavity, and the first connecting plate extends into the first accommodating cavity and is connected to the cross beam. The first accommodating cavity can facilitate the hiding and protection of the first connecting plate and improve the connection reliability between the cross beam and the fixed seat.
[0014] In some embodiments, the fixing seat is provided with a boss, the sleeve is rotatably mounted on the boss, the boss is provided with a stopper, and the stopper can block the rotation of the sleeve. The boss can limit the sleeve to a certain extent, reducing the occurrence of erroneous movement of the sleeve other than rotation, and the stopper can serve as the rotatable end point of the rotating member, so as to avoid excessive rotation of the sleeve of the rotating member to cause failure of other structures as much as possible, such as preventing the sleeve from rotating outwardly so that the convex block passes over the second convexity, making it difficult to reset the temple, or preventing the sleeve from being excessively folded inwardly so that the leaf spring is overly compressed and damaged, etc.
[0015] In some embodiments, the rotating member is provided with a second connecting plate, the temple is provided with a second accommodating cavity, the second connecting plate extends into the second accommodating cavity and is connected to the temple. The second accommodating cavity can hide and protect the second connecting plate, thereby improving the connection reliability between the temple and the rotating member.

DETAILED DESCRIPTION
[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0024] refer to Figures 1 to 6 The utility model discloses an inside-outside folding structure for glasses, comprising a frame 1, temples 2, a fixing seat 3, a rotating member 4, a pin structure and a leaf spring 6.
[0025] A crossbeam 11 is disposed at the end of the frame 1 . The crossbeam 11 is disposed perpendicular to the frame body. A first accommodating cavity 12 is disposed in the crossbeam 11 .
[0026] A first connecting plate 31 is provided on the fixing seat 3 . The first connecting plate 31 extends into the first accommodating cavity 12 and is connected to the inner wall of the first accommodating cavity 12 by bolts, so that the fixing seat 3 and the crossbeam 11 are fixedly connected.
[0027] A second accommodating cavity is provided at one end of the temple 2, and a second connecting plate 41 is provided on the rotating member 4. The second connecting plate 41 extends into the second accommodating cavity, and the second connecting plate 41 is connected to the inner wall of the second accommodating cavity by bolts, so that the rotating member 4 and the temple 2 are fixedly connected.
[0028] The fixing seat 3 is further provided with a pin seat 32 and a boss 33 . The central axis of the boss 33 overlaps with the central axis of the pin seat 32 , and the pin seat 32 is connected to the boss 33 in an integral manner.
[0029] The rotating member 4 is provided with a sleeve 42 and a top plate 43 , wherein the top plate 43 is integrally connected to the top of the sleeve 42 , and the second connecting plate 41 is integrally connected to the side of the sleeve 42 .
[0030] The pin structure includes a pin 51 and a retaining spring 52, and a through hole is provided in the middle of the pin seat 32, and a through hole is also provided in the middle of the top plate 43. The top plate 43 is placed on the pin seat 32, so that the through hole on the top plate 43 is opposite to and connected with the through hole on the pin seat 32, and one end of the pin 51 passes through the through hole of the pin seat 32 and the through hole of the top plate in sequence and then passes out, and the other end of the pin 51 can be provided with a screw head, and a clamping position is provided on the passing end of the pin 51, and the top plate 43 is also provided with a concave position at its through hole, and the retaining spring 52 is placed in the concave position and clamped on the clamping position of the pin 51 so that the end of the pin 51 and the retaining spring 52 are fixedly connected. Thus, the rotating member 4 is rotatably mounted on the fixed seat 3 through the pin structure.
[0031] A groove 321 is also provided on the side of the pin shaft seat 32. The leaf spring 6 is provided with an arc portion 61. The arc portion 61 is sleeved on the pin shaft seat 32. One end of the arc portion 61 is provided with a folding foot 611. The folding foot 611 is embedded in the groove 321. The other end of the arc portion 61 is provided with a straight portion 612. Relying on the elastic force of the leaf spring 6, its straight portion 612 abuts against the first connecting plate 31, so that the leaf spring 6 is installed on the fixed seat 3. After the leaf spring 6 and the rotating member 4 are arranged, the kit 42 of the rotating member 4 will be located on the periphery of the leaf spring 6.
[0032] A convex block 60 is provided on the arc portion 61 of the leaf spring 6. The inner wall of the kit 42 is provided with a first protrusion 421 and a second protrusion 422. After the leaf spring 6 and the rotating member 4 are arranged, the convex block 60 can slightly abut against the inner wall of the kit 42, and the convex block 60 is arranged between the first protrusion 421 and the second protrusion 422.
[0033] After the rotating member 4 is arranged, the kit 42 is also rotatably sleeved on the periphery of the boss 33. A stop block 31 is provided on the side of the boss 33. The stop block 31 can block the rotation of the kit 42, that is, the kit 42 cannot pass through the stop block 31 when it is forced to rotate. The setting position of the stop block 31 can be used as the rotational end point of the kit 42 to avoid excessive rotation of the kit 42.
[0034] When the utility model is in use, the rotating member 4 can rotate on the fixed seat 3, so that the temple 2 and the spectacle frame 1 respectively connected thereto can rotate relative to each other to realize the inward folding or outward folding and opening of the temple 2. After the temple 2 is folded outward and opened, without external force, at this time, the elastic force of the leaf spring 6 can be relied on to maintain the contact between the convex block 60 of the leaf spring 6 and the inner wall of the kit 42 of the rotating member 4, so as to maintain the current open position of the temple 2 for the convenience of the user to wear.
[0035] When the temple 2 is folded inward, that is, when the user applies a force to the temple 2 to move the temple 2 toward the direction close to the spectacle frame 1, under the external force, the rotating member 4 can rotate, then the first protrusion 421 of the kit 42 will move correspondingly to contact the convex block 60, and the leaf spring 6 is compressed. At this time, the leaf spring 6 can provide the feel of the inward folding of the temple 2 until the convex block 60 passes over the first protrusion 421. At this time, the inward folding of the temple 2 is completed, and the leaf spring 6 relies on its elastic force again to make the convex block 60 abut against the inner wall of the kit 42 of the rotating member 4 and maintain the current position without force, that is, maintain the folded state of the temple 2. In addition, the first protrusion 421 can be set according to the required feel.
[0036] Similarly, when the temple 2 is unfolded and opened outward, the first protrusion 421 can be re-oriented towards the bump 60 and can come into contact with the bump 60, and the leaf spring 6 is compressed again to provide the feel when the temple 2 is opened until the bump 60 reversely crosses the first protrusion 421, achieving the opening of the temple 2. At this time, the bump 60 of the leaf spring 6 can be relied on the elastic force of the leaf spring 6 to abut against the inner wall of the sleeve 42 of the rotating member 4, maintaining the current open position of the temple 2.
[0037] When the temple 2 is excessively unfolded outward to a certain extent under an external force, the bump 60 can come into contact with the second protrusion 422 to compress the leaf spring 6, buffering the external force. When the external force stops being applied without the bump 60 exceeding the second protrusion 422 in the outward folding amplitude, the leaf spring 6 can separate from the second protrusion 422 by relying on its elasticity and reset to the normal open position of the temple 2, and the bump 60 of the leaf spring 6 can be relied on its elastic force to abut against the inner wall of the sleeve 42 of the rotating member 4. In addition, the relative movement limit position between the second protrusion 422 and the bump 60 can be achieved by the limit of the stopper 31 on the sleeve 42.
[0038] Therefore, in the present utility model, there is a good feel when the temple 2 is folded inward, and the folded state of the temple 2 can be effectively maintained after folding. At the same time, there is a certain tolerance space for further outward folding after the temple 2 is folded outward, buffering the external force, and it can still return to the normal open state after a certain external force ends, with strong reliability.
[0039] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
