Description

Technical Field

[0001] The present application relates to the field of glasses, and in particular to a chain adapter module and glasses. Background Art

[0002] With the development of smart glasses, users have higher and higher requirements for wearing comfort. However, the inside of the temples of smart glasses are stacked with components such as circuit boards, batteries, and speakers, which cannot be deformed. The frames may also be equipped with components such as cameras or sensors. Therefore, the deformation that the frames can provide is relatively small. Therefore, when users with different head sizes wear them, they are prone to wearing them too loose or too tight, resulting in lower wearing comfort for users. Summary of the Invention

[0003] In order to adapt to different head sizes while maintaining the wearing comfort of glasses, the present application provides a chain adapter module and glasses.

[0004] In a first aspect, the present application provides a link transfer module, which adopts the following technical solution: A chain adapter module is used for glasses, wherein the glasses include a frame and temples, and the chain adapter module includes: A frame node block, used for detachably hinged connection with the mirror frame; A leg connecting node block, used for detachably connecting to the temple; An elastic adapter block, one end of which is for the frame-connecting node block to be embedded in, and the other end of which is for the leg-connecting node block to be embedded in. The posture stability between the temple and the frame is maintained by the embeddedness of the frame-connecting node block and the leg-connecting node block. The elastic adapter block is provided with an auxiliary clamping groove on the side close to the temple not connected to it. The bottom of the auxiliary clamping groove is set in an arc surface transition. The arc bottom of the auxiliary clamping groove is located at the part of the elastic adapter block that is not embedded in the frame-connecting node block and the leg-connecting node block. The auxiliary clamping groove is used to increase the deformation of the elastic adapter block in the direction away from the temple not connected to it, and the elastic adapter block is subjected to a twisting deformation with its twisting axis perpendicular to the hinge axis direction of the frame-connecting node block and perpendicular to the length direction of the temple.

[0005] By adopting the above technical solution, under the coordinated action of the elastic adapter block and the auxiliary clamping groove, firstly, the deformation of the elastic adapter block itself can adapt to heads of different sizes, and the auxiliary clamping groove will make the deformation angle of the elastic adapter block larger than the angle between the temple and the frame, so as to provide sufficient and moderate clamping force while the head size changes within a small range, thereby being stably and comfortably worn on heads of different sizes; secondly, when temporarily stored, the elastic adapter block can also be twisted with the twisting axis perpendicular to the hinge axis direction of the frame node block and perpendicular to the length direction of the temple, so that the part of the temple away from the frame can be folded to the front side of the frame, thereby forming a barrier protection for the front and back sides of the frame, so that when the glasses are temporarily stored in a pocket or temporarily placed on a table, foreign objects can be prevented from directly contacting the lenses, thereby protecting the lenses; in addition, under the built-in action of the frame node block and the leg node block, only the middle position of the elastic adapter block can be deformed, which can reduce the shaking amplitude of the temple relative to the frame, thereby maintaining the stability of the glasses when worn.

[0006] Preferably, the bottom of the clamping-aiding through groove is concave and wavy.

[0007] By adopting the above technical solution, while maintaining the thickness of the elastic adapter block, the deformation of the elastic adapter block of the temple at the same expansion angle can be further increased, thereby providing more sufficient clamping force.

[0008] Preferably, the frame-connecting node block and the leg-connecting node block are both integrally connected to the elastic transition block.

[0009] By adopting the above technical solution, since various electronic devices on the smart glasses will be installed on the frame and temples, the elastic adapter block, frame and temples need to be separated during maintenance. At the same time, from the perspective of installation convenience, the frame node block and the leg node block are connected to the elastic adapter block as one piece, which is convenient for separating the elastic adapter block, frame and temples, and also convenient for connecting the elastic adapter block, frame and temples.

[0010] Preferably, the portion of the frame node block exposed from the elastic adapter block is provided with a connecting shaft, the connecting shaft is in a cam structure, the distal rest portion of the connecting shaft is used to abut against the hinge hole wall on the frame, and the proximal rest portion of the connecting shaft is used to set a gap with the hinge hole wall on the frame.

[0011] By adopting the above technical solution, the hinge between the frame node block and the mirror frame is realized, and the assembly and disassembly between the frame node block and the mirror frame is also realized, and the hinge structure between the frame node block and the mirror frame has strong stability.

[0012] Preferably, the leg node block and the temple are connected in an interlocking manner.

[0013] By adopting the above technical solution, while achieving the detachability between the temple and the elastic adapter block, the shapes of the elastic adapter block, the temple node block and the temple can transition smoothly and be thinner, thereby improving the simplicity of the shape of the glasses.

[0014] Preferably, two reverse shaping blocks are provided on the side of the elastic adapter block away from the non-connected temple, and the two reverse shaping blocks are respectively located on the two ends of the elastic adapter block. The reverse shaping block has a U-shaped bending structure, and the bending opening of the reverse shaping block is away from the elastic adapter block. The two reverse shaping blocks are used for interference embedding of the external annular component.

[0015] By adopting the above technical solution, when simple maintenance of the electronic components on the frame is required, the temples can be flipped outward until the temples are 180° to the frame. At this time, the outer annular member is passed through two reverse shaping blocks on an elastic adapter block to stably maintain the temples at an angle of 180° to the frame, so that maintenance work on the electronic components on the frame can be carried out without disassembling the temples.

[0016] In a second aspect, the present application provides a link transfer module, which adopts the following technical solution: A chain adapter module is used for glasses, wherein the glasses include a frame and temples, and the chain adapter module includes: A frame-connecting node block, used for detachably hinged connection with the mirror frame; A leg connecting node block, used for detachably connecting to the temple; The elastic adapter block is in the shape of a hollow tube, with the frame node block and the leg node block respectively embedded at both ends. The elastic adapter block is provided with clip-receiving grooves on two sides close to and away from the non-connected temples, and the bottom of the clip-receiving grooves extends in a wave shape along the length direction of the elastic adapter block. The positioning clips are clamped in different troughs of the receiving clip slots.

[0017] By adopting the above technical solution, the position of the narrowed part of the elastic adapter block can be changed by changing the position of the positioning clip to change the deformation center of the elastic adapter block. Under the effect of the change in the position of the deformation center, the deformation angle of the elastic adapter block can be changed while the angle between the temple and the frame is the same, so as to slightly adjust the clamping force of the temple, thereby improving wearing comfort.

[0018] Preferably, the positioning clamp includes a mounting plate, a clamping rod, a clamping spring, a connecting ring, a mounting post and an operating cover, the mounting plate abuts the surface of the elastic adapter block adjacent to the clamping slot, the mounting plate is provided with a sliding hole, the length direction of the sliding hole is parallel to the connecting direction between the two clamping slots; the sliding hole is passed through one end of the clamping rod, and the two clamping rods are respectively embedded in the two clamping slots; the clamping springs respectively connect the two ends of the clamping rods away from the sliding holes; the connecting ring is threadedly sleeved on the end of the clamping rod away from the clamping spring, and the connecting ring is located on the side of the mounting plate away from the clamping spring; the mounting post is connected to the side of the mounting plate away from the clamping spring; the operating cover is threadedly sleeved on the mounting post, and a conical clamping guide surface is provided on the side of the operating cover close to the mounting plate, and the clamping guide surface abuts the clamping rod.

[0019] By adopting the above technical solution, rotating the operating cover to change the contact of the clamping rod on the clamping guide surface, and cooperating with the clamping spring, the two clamping rods can be brought closer and farther away, thereby realizing the opening and clamping of the positioning clamp.

[0020] Preferably, the parts of the frame node block and the leg node block connected to the elastic adapter block are both set as node internal connection parts, and the opposite side surfaces of the node internal connection part are provided with connecting teeth and damping blocks, the damping block is arranged adjacent to the connecting teeth, and the end of the damping block close to the middle position of the elastic adapter block is thicker than the end away from the middle position of the elastic adapter block; the elastic adapter block is provided with connecting tooth grooves, damping surfaces and separation margin grooves at a position matching with the node internal connection part, the connecting tooth grooves are meshed with the connecting teeth, the damping surface abuts against the damping block, and the separation margin groove is provided on the inner wall of the elastic adapter block that does not match with the connecting teeth, and is used to transfer the margin space provided by the separation margin groove to the inner wall matching with the connecting teeth when the elastic adapter block is squeezed.

[0021] By adopting the above technical solution, firstly, when the elastic adapter block is squeezed to close the separation margin groove, the margin space provided by the separation margin groove will be transferred to the inner wall that cooperates with the connecting teeth, so that the connecting teeth and the connecting tooth grooves are loosened, so that the node inner connection part can be pulled out of the elastic adapter block to achieve the distance adjustment between the node inner connection part and the middle position of the elastic adapter block, or the node inner connection part can be pulled out from the elastic adapter block, thereby achieving the distance adjustment between the temple and the frame, and also achieving the independent separation of the elastic adapter block. In addition, in the process of pulling out the node inner connection part, the cooperation between the damping block and the damping surface can make the node inner connection part farther away from the middle position of the elastic adapter block, the greater the force required to pull it out, thereby maintaining the connection stability between the elastic adapter block and the node inner connection part; secondly, since the connecting teeth and the connecting tooth grooves are used to achieve the connection and cooperation between the node inner connection part and the elastic adapter block, the position of the positioning clamp can be changed according to the situation that the two node inner connections extend out of the elastic adapter block to maintain the connection stability between the elastic adapter block and the node inner connection part.

[0022] In a third aspect, the present application provides a pair of glasses, which adopts the following technical solution: A pair of glasses comprises a frame, temples and a chain transfer module, wherein the chain transfer module connects the frame and the temples.

[0023] By adopting the above technical solution, the glasses can be comfortably worn by users with different heads.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Under the synergistic effect of the elastic adapter block and the auxiliary clamping slot, firstly, the elastic adapter block itself can be deformed to adapt to heads of different sizes. The auxiliary clamping slot will make the deformation angle of the elastic adapter block larger than the angle between the temple and the frame, so as to provide sufficient clamping force when the head size changes slightly, thereby stably wearing it on heads of different sizes; secondly, when temporarily stored, the elastic adapter block can also be twisted with the twist axis perpendicular to the hinge axis direction of the frame node block and perpendicular to the length direction of the temple, so that the part of the temple away from the frame is folded to the front side of the frame, thereby forming a barrier protection for the front and back sides of the frame. Therefore, when the glasses are temporarily stored in a pocket or on a table, foreign objects can be prevented from directly contacting the lenses, thereby playing a role in protecting the lenses; in addition, under the built-in effect of the frame node block and the leg node block, only the middle position of the elastic adapter block can be deformed, which can reduce the shaking amplitude of the temple relative to the frame, thereby maintaining the stability of the glasses when worn; 2. Since the various electronic devices on the smart glasses are installed on the frame and temples, the elastic adapter block, frame and temples need to be separated during maintenance. At the same time, from the perspective of installation convenience, the frame node block and the temple node block are connected to the elastic adapter block as one piece, which is convenient for separating the elastic adapter block, frame and temples, and also convenient for connecting the elastic adapter block, frame and temples.

[0033] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0034] The embodiment of the present application discloses a link switching module.

[0035] Example 1.

[0036] Reference Figure 1 , the chain adapter module will be used on the glasses. The glasses as a whole include a frame 1 and temples 2. The chain adapter module will be used to connect the frame 1 and the temples 2. Specifically, the chain adapter module will include a frame node block 3, a leg node block 4 and an elastic adapter block 5. The frame node block 3 is made of hard rubber material, and the frame node block 3 is hinged to the frame 1; the leg node block 4 is also made of hard rubber material, and the leg node block 4 is connected to the temple 2; the elastic adapter block 5 is made of soft rubber material, and the elastic adapter block 5 is a solid structure. The elastic adapter block 5 is thicker than the frame node block 3 and The leg node block 4 should be softer, and at the same time, one end of the elastic adapter block 5 is embedded in the frame node block 3, and the other end is embedded in the leg node block 4. Through the built-in frame node block 3 and leg node block 4, only the middle position of the elastic adapter block 5 can be deformed, while the positions at both ends are more difficult to deform. In this way, the amplitude of the up and down shaking of the temple 2 will be smaller, so as to maintain the posture stability between the temple 2 and the frame 1, that is, when wearing glasses, the temple 2 will not shake around when the head touches the temple 2, thereby improving the convenience of using the glasses.

[0037] Reference Figure 1 The elastic adapter block 5 is integrally provided with an auxiliary clamping groove 51 on the side close to the non-connected temple 2, that is, the left elastic adapter block 5 is provided with an auxiliary clamping groove 51 on the side close to the right temple 2, or the right elastic adapter block 5 is provided with an auxiliary clamping groove 51 on the side close to the left temple 2. The communication direction of the auxiliary clamping groove 51 is parallel to the axis of the hinge axis of the frame node block 3, and the bottom of the auxiliary clamping groove 51 is set in an arc surface transition. The arc bottom of the auxiliary clamping groove 51 is located at the part of the elastic adapter block 5 that is not embedded in the frame node block 3 and the leg node block 4, that is, roughly at the length of the elastic adapter block 5. In the middle position of the degree, with the help of the auxiliary clamping groove 51 which is similar to the concave structure, when the elastic adapter block 5 is deformed, the elastic adapter block 5 needs to first recover from the concave to the flat, and then deform from the flat to the convex. In this way, when the temple 2 and the frame 1 have the same angle, the deformation of the elastic adapter block 5 will be larger. The advantage is that even if the size of the head changes slightly, the deformation of the elastic adapter block 5 can provide sufficient clamping force to improve the wearing stability, and this clamping force is provided by the elastic deformation, so the size of the clamping force is also moderate, which can also improve the wearing comfort.

[0038] Reference Figure 1 In addition, due to the setting of the auxiliary clamping groove 51, the elastic adapter block 5 can be twisted with its twist axis perpendicular to the hinge axis of the frame node block 3 and perpendicular to the length direction of the temple 2, that is, it can be twisted according to the direction of the temple. Figure 1The temple 2 can be swung in the up and down directions. The advantage of doing so is that the temple 2 can be flipped away from one end of the frame 1 to the front side of the frame 1 to form a barrier protection for the front and back sides of the frame 1, that is, external elements cannot directly contact the lenses from the front or back, so the glasses can be temporarily stored in a pocket or on a temporary table, thereby improving the convenience of using the glasses.

[0039] In summary, the above-mentioned glasses have the following advantages: first, they are adaptable to heads of different sizes and have appropriate clamping force; second, they can protect the lenses when temporarily stored; third, the overall structure of the glasses is relatively stable and easy to wear.

[0040] Reference Figure 1 Taking into account the size limitation of the elastic adapter block 5, this limitation means that the thickness of the elastic adapter block 5 should not be too large or too small. If it is too large, the overall size ratio of the glasses will be inconsistent. If it is too small, the elastic force provided by the elastic adapter block 5 will be insufficient. Since the auxiliary clamping groove 51 in this application makes the middle position of the elastic adapter block 5 thinner, in order to be compatible with the simple size and sufficient elastic force, the bottom of the auxiliary clamping groove 51 is concave in a wavy line, that is, it will be appropriately concave a little more, so as to slightly increase the deformation angle of the elastic adapter block 5 while maintaining the minimum size requirement, so that the clamping force can be more sufficient.

[0041] Reference Figure 1 In the field of smart glasses, most electronic components are installed on the frame 1 and the temples 2. When maintaining the electronic components, the frame 1 and the temples 2 need to be disassembled, that is, the frame 1, the temples 2 and the elastic adapter block 5 need to be separated. However, it should be considered that since the separation between the frame 1, the temples 2 and the elastic adapter block 5 does not happen frequently, and the stability of the overall structure of the glasses needs to be considered, it is relatively difficult to disassemble the elastic adapter block 5 from the temples 2 and the frame 1. The difficulty here mainly refers to the fact that a large force may be required to achieve a strong separation between the components. In order to facilitate maintenance, In order to separate the three components, it is preferred that the frame node block 3 and the leg node block 4 are integrally connected with the elastic adapter block 5. Specifically, during the production, after the frame node block 3 and the leg node block 4 are made, they are sent into the injection mold and then the elastic adapter block 5 is made, so that the elastic adapter block 5 can integrally cover the frame node block 3 and the leg node block 4. In this way, the staff can hold the elastic adapter block 5 to apply enough force to separate the frame node block 3 from the frame 1, and to separate the leg node block 4 from the temple 2. Similarly, during assembly, the staff can also hold the elastic adapter block 5 to operate, which facilitates the assembly of the various components in the glasses.

[0042] Reference Figure 1 and Figure 2In this embodiment, in order to realize a stable and detachable hinge between the connecting frame node block 3 and the frame 1, the following settings are correspondingly provided: the portion of the connecting frame node block 3 exposed outside the elastic adapter block 5 is integrally formed with a connecting shaft 31, and the connecting shaft 31 is a cam structure, wherein the connecting shaft 31 is a symmetrical cam structure, that is, from a circumferential perspective, there are two relatively arranged distal rest portions and two relatively arranged proximal rest portions, the distal rest portions and the proximal rest portions are adjacent to each other, wherein the distal rest portions are the two sides with a larger shaft diameter, and the proximal rest portions are the two sides with a smaller shaft diameter, and at the same time, the frame 1 will be provided with a hinge. The hole 11 and the entry channel 12 connected to the hinge hole 11, the distal rest portion of the connecting shaft 31 abuts against the hole wall of the hinge hole 11 on the frame 1 to realize the rotation of the connecting shaft 31 in the hinge hole 11, and a gap is set between the proximal rest portion of the connecting shaft 31 and the hole wall of the hinge hole 11 on the frame 1, and the width of the entry channel 12 is smaller than the diameter of the hinge hole 11. When the proximal rest portion of the connecting shaft 31 is aligned with the entry channel 12, that is, when the temple 2 is parallel to the frame 1, the connecting shaft 31 can be pulled out of the frame 1 to realize the separation between the frame node block 3 and the frame 1.

[0043] Reference Figure 1 In this embodiment, under the premise of a detachable connection between the leg node block 4 and the temple 2 that can be separated by strong force, in order to further make the shapes of the elastic adapter block 5, the leg node block 4 and the temple 2 transition smoothly and thinner, the smoothness here means that when looking along the direction of the elastic adapter block 5, the leg node block 4 and the temple 2, there will be no sudden bulge or recess in any place. It is preferred that the leg node block 4 and the temple 2 are connected in an interlocking manner. Specifically, the leg node block 4 may be provided with a groove or hole, and the groove or hole is for the temple 2 to be inserted through interference. Alternatively, the temple 2 may be provided with a groove, and the end of the leg node block 4 exposed outside the elastic adapter block 5 is inserted through interference in this groove, thereby achieving the detachability between the leg node block 4 and the temple 2 and making the shape of the glasses more concise.

[0044] Reference Figure 1 and Figure 3 In other embodiments, a groove is provided in the temple 2, and the leg node block 4 is inserted into the groove. A buckle block 41 can be provided on the portion of the leg node block 4 exposed from the elastic adapter block 5. At the same time, a buckle hole 21 can be provided in the groove of the temple 2. During assembly, the temple 2 is forcefully put on the portion of the leg node block 4 exposed outside the elastic adapter block 5 so that the buckle block 41 is automatically embedded in the buckle hole 21. During disassembly, the buckle block 41 is squeezed from the position of the buckle hole 21. After the buckle block 41 is separated from the buckle hole 21, the temple 2 can be separated from the leg node block 4. Although this method increases the difficulty of separating the temple 2 from the leg node block 4, it can also prevent the temple 2 from being accidentally pulled out.

[0045] Reference Figure 1 and Figure 4 The two temples 2 are respectively located at the two ends of the elastic adapter block 5, that is, close to the two ends of the frame 1 and the temple 2. At the same time, the reverse shaping block 52 is U-shaped and bent. The bending opening of the reverse shaping block 52 is away from the elastic adapter block 5. When the temple 2 is turned outward to form an angle of 180° with the frame 1, an annular component can be inserted from the outside through the bending opening of the reverse shaping block 52 so that the annular component is interference-embedded in the two reverse shaping blocks 52. Therefore, the temple 2 can be kept in a 180° turned-out posture with the help of an external component, so that the maintenance work of the electronic components on the frame 1 can be achieved without disassembling the temple 2.

[0046] The implementation principle of a chain adapter module in an embodiment of the present application is as follows: under the coordinated action of the elastic adapter block 5 and the auxiliary clamping groove 51, firstly, the deformation of the elastic adapter block 5 itself can adapt to heads of different sizes, and the auxiliary clamping groove 51 will make the deformation angle of the elastic adapter block 5 larger than the angle between the temple 2 and the frame 1, so as to provide sufficient clamping force when the head size changes within a small range, so that it can be stably worn on heads of different sizes; secondly, during temporary storage, the elastic adapter block 5 can also be twisted so that the axis is perpendicular to the hinge axis direction of the frame node block 3 and perpendicular to the frame node block 3. The temple 2 is twisted in the length direction so that the part of the temple 2 away from the frame 1 is folded to the front side of the frame 1, which can form a barrier protection for the front and back sides of the frame 1. Therefore, when the glasses are temporarily stored in a pocket or temporarily placed on a table, foreign objects can be prevented from directly contacting the lenses, thereby protecting the lenses; in addition, under the built-in action of the frame node block 3 and the leg node block 4, only the middle position of the elastic adapter block 5 can be deformed, which can reduce the shaking amplitude of the temple 2 relative to the frame 1, thereby maintaining the stability of the glasses when worn.

[0047] Example 2.

[0048] Reference Figure 5 and Figure 6The chain adapter module includes a frame node block 3, a leg node block 4, an elastic adapter block 5 and a positioning clip 6, wherein the material of the frame node block 3 and the matching structure with the frame 1 are the same as those in the aforementioned embodiment 1, and the material of the leg node block 4 and the matching structure with the temple 2 are also the same as those in the aforementioned embodiment 1; the elastic adapter block 5 is in the shape of a hollow square tube, and the two ends are also respectively provided with a frame node block 3 and a retreat node block for embedding, but the elastic adapter block 5 is integrally provided with a clip-receiving groove 53 on the two side surfaces close to and away from the non-connected temple 2, and the clip-receiving groove 53 is roughly located in the middle position of the elastic adapter block 5, that is, the part of the elastic adapter block 5 that is not connected to the frame node block 3 and the leg node block 4, and at the same time, the groove bottom of the clip-receiving groove 53 extends in a wavy line along the length direction of the elastic adapter block 5 to form a trough-like structure at different positions along the length direction of the elastic adapter block 5.

[0049] Reference Figure 5 and Figure 6 The positioning clip 6 is set on the elastic adapter block 5 in a clamping manner, and the positioning clip 6 will be clamped in different troughs of the clamping groove 53 to achieve that different positions of the elastic adapter block 5 are clamped, and when the elastic adapter block 5 is bent and deformed, the deformation is also mainly concentrated at the clamped position. Therefore, by changing the position of the positioning clip 6, the deformation center of the elastic adapter block 5 can be changed. When the eversion angle of the temple 2 is the same, the closer the deformation center is to the frame 1, the smaller the deformation of the elastic adapter block 5, and the farther the deformation center is from the frame 1, the larger the deformation of the elastic adapter block 5. Based on the above adjustment method, the clamping force of the temple 2 can be slightly adjusted while adapting to different sizes of heads, thereby improving wearing comfort.

[0050] Reference Figure 5 and Figure 6 In order to facilitate the user to use the positioning clamp 6, the positioning clamp 6 includes a mounting plate 61, a clamping rod 62, a clamping spring 63, a connecting ring 64, a mounting post 65 and an operating cover 66. The mounting plate 61 abuts the surface of the elastic adapter block 5 adjacent to the clamping slot 53, and the mounting plate 61 is provided with a sliding hole 611, the length direction of the sliding hole 611 is parallel to the width direction of the elastic adapter block 5; the clamping rod 62 is cylindrical in shape, and one end of the clamping rod 62 is penetrated by the sliding hole 611, and the two clamping rods 62 are respectively embedded in the two clamping slots 53; the clamping springs 63 respectively connect the two clamping rods 62 at one end away from the sliding hole 611, and the clamping springs 63 provide the two clamping rods 62 with a force to move closer to each other; the connecting ring 64 is threadedly sleeved on the end of the clamping rod 62 away from the clamping spring 63, and the connecting ring 64 is located on the side of the mounting plate 61 away from the clamping spring 63, so as to realize the installation of the clamping rod 62 on the mounting plate 61.

[0051] Reference Figure 5 and Figure 6The mounting post 65 is connected to the side of the mounting plate 61 away from the clamping spring 63. The mounting post 65 is cylindrical and extends in the direction away from the elastic adapter block 5; the operating cover 66 is threadedly sleeved on the mounting post 65, and the operating cover 66 is in the shape of a cone cap as a whole, so the operating cover 66 is formed with a conical clamping guide surface 661 on the side close to the mounting plate 61. The clamping guide surface 661 abuts against the clamping rod 62. By rotating the operating cover 66, the abutment contact of the clamping rod 62 on the clamping guide surface 661 can be changed, and by cooperating with the clamping spring 63, the two clamping rods 62 can be brought closer and farther away, thereby realizing the opening and clamping of the positioning clamp 6.

[0052] Reference Figure 5 and Figure 7 At the same time, in this embodiment, since the elastic adapter block 5 is made of soft rubber material, the elastic adapter block 5 can have different colors. In order to facilitate the user to assemble glasses in a personalized manner, it is hoped that the elastic adapter block 5 can be simply separated from the frame node block 3 and the leg node block 4. Therefore, the connection structure between the frame node block 3 and the leg node and the elastic adapter block 5 will be optimized. For the convenience of description, the parts where the frame node block 3 and the leg node block 4 are connected to the elastic adapter block 5 are all set as node internal connection parts 7. Specifically, firstly, connecting teeth 71 and damping blocks 72 are formed on the opposite side surfaces of the node internal connection part 7. The connecting teeth 71 are in a rack structure, and the damping block 72 is adjacent to the connecting teeth 71. The adjacent direction is along the thickness direction of the elastic adapter block 5. At the same time, the damping block 72 is in a triangular prism structure, wherein the damping block 72 is thicker at the end close to the middle position of the elastic adapter block 5 and thinner at the end away from the middle position of the elastic adapter block 5.

[0053] Reference Figure 5 and Figure 7 Secondly, the elastic adapter block 5 is provided with a connecting tooth groove 54, a damping surface 55 and a separation margin groove 56 at the position cooperating with the node internal connection part 7. The connecting tooth groove 54 is engaged with the connecting tooth 71. This engagement is an engagement with a certain interference fit. The damping surface 55 is in contact with the damping block 72. The shape and structure of the damping surface 55 are matched with the damping block 72, so that the elastic adapter block 5 is thinner in the area where the damping surface 55 is located, and the part away from the middle part is thicker. The separation margin groove 56 is located on the inner wall of the elastic adapter block 5 that does not cooperate with the connecting tooth 71. The separation margin groove 56 will leave a gap between the node internal connection part 7 and the inner wall of the elastic adapter block 5.

[0054] Reference Figure 5 and Figure 7 The working principle of disassembly is as follows: squeeze the elastic adapter block 5 to close the separation margin groove 56, that is, squeeze the two sides of the non-clamping groove 53 on the elastic adapter block 5, more specifically Figure 7When the elastic adapter block 5 is squeezed in the up and down directions, the margin space provided by the separation margin groove 56 will be transferred to the inner wall that cooperates with the connecting tooth 71, so that the connecting tooth 71 and the connecting tooth groove 54 are loosened, so that the node internal connection part 7 can be pulled out of the elastic adapter block 5, thereby realizing the separation between the frame node block 3 and the leg node block 4 and the elastic adapter block 5. In addition, in the process of pulling out the node internal connection part 7, the cooperation between the damping block 72 and the damping surface 55 can make the node internal connection part 7 farther away from the middle position of the elastic adapter block 5, the greater the force required to pull it out, thereby maintaining the connection stability between the elastic adapter block 5 and the node internal connection part 7, that is, appropriately increasing the difficulty of disassembly and enhancing the connection stability.

[0055] Reference Figure 5 and Figure 7 In addition, based on the matching structure between the node inner connecting part 7 and the elastic adapter block 5, the distance between the node inner connecting part 7 and the middle position of the elastic adapter block 5 can also be changed, so that the distance between the temple 2 and the frame 1 can be changed. At the same time, with the help of the matching of the damping block 72 and the damping surface 55, the farther the node inner connecting part 7 is from the middle position of the elastic adapter block 5, the tighter the interference fit between the node inner connecting part 7 and the elastic adapter block 5, so as to maintain the posture stability among the temple 2, the frame 1 and the elastic adapter block 5.

[0056] Reference Figure 5 and Figure 7 In this embodiment, most of the connecting force between the node inner connecting part 7 and the elastic adapter block 5 comes from the cooperation between the connecting teeth 71 and the connecting tooth grooves 54, and the cooperation between the teeth and the tooth grooves depends on the number of engaged teeth. However, when the node inner connecting part 7 is partially pulled out of the elastic adapter block 5, the connection stability between the node inner connecting part 7 and the elastic adapter block 5 will be weakened to a certain extent. At this time, the positioning clip 6 can be moved closer to compensate for the weakening of the connection caused by the insufficient number of engaged teeth. Specifically, for example, when the distance between the elastic adapter block 5 and the frame 1 is smaller than the distance between the elastic adapter block 5 and the temple 2, the positioning clip 6 can be moved closer to the temple 2, so that the stability of the entire glasses structure can be maintained while changing the distance between the temple 2 and the frame 1.

[0057] The present application also discloses a pair of glasses. Figure 1 and Figure 5The glasses include a frame 1, temples 2 and a chain adapter module. The chain adapter module adopts the solution adopted in the above two embodiments. With the help of the characteristics of the chain adapter module, the following functions can be achieved: 1. Stable and comfortable wearing on heads of different sizes; 2. Protection of lenses in temporary storage scenarios; 3. High structural stability of the glasses; 4. The glasses are easy to separate various components for maintenance work or user personalized design; 5. The structure of the glasses is simple and the shape transitions between different positions are very smooth, so as to enhance the aesthetics of wearing.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
