Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an easy-to-replace structure for eyeglass temple tips. Background Technology

[0002] The frames and temples of eyeglasses are connected by hinges. The temples open and close at a certain angle around the hinges to facilitate wearing or storing the eyeglasses. The hinge assembly generally consists of a hinge base and a hinge head, which are fixedly connected to the frame post and temple respectively. Then, the hinge holes are aligned and pins are inserted to complete the assembly of the temples and frames.

[0003] The problem with existing technology is that modern glasses not only solve vision problems, but consumers also need them to match clothing and adapt to different occasions. For example, by changing the temples to different colors and styles, they can match their outfits. Also, when wearers are exercising, excessive sweating can cause the temples to slip, necessitating the replacement with temples made of sweat-absorbing and non-slip materials.

[0004] These common needs require that the temples of glasses can be quickly and easily replaced. However, traditional glasses require tools such as screwdrivers to assemble, which is cumbersome for consumers to carry around, and the assembly process cannot be adapted to different consumers.

[0005] Therefore, a quick-release mechanism for the temple components should be designed so that consumers can easily replace the temples according to their needs. The disassembly and assembly process should be designed to avoid affecting the hinge structure and to prevent frequent temple replacements that could damage the hinge. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this invention provides an easy-to-replace structure for eyeglass temple tips.

[0007] The technical solution of this utility model is as follows: an easily replaceable structure for eyeglass temples, including a frame, temples, hinge heads, and hinge seats. The hinge seat includes a hinge end and a plug end. The plug end is coaxially provided with a mating groove, and an axial limiting groove is provided at the mating groove. The temple includes a pin and a housing. One end of the pin is provided with a plug part, and the other end is inserted into the housing for a detachable fixed connection. The plug part is provided with an elastic mechanism and an axial limiting member. The plug part is inserted into the mating groove, and the elastic mechanism drives the axial limiting member to elastically engage with the axial limiting groove.

[0008] A further feature of this invention is that the axial limiting groove is a through groove that extends radially into the mating groove. The axial limiting groove includes a spiral portion and a fold-back portion. The spiral portion extends from the insertion end along the outer circumferential surface toward the hinge end. The spiral portion includes a first groove opening and a first groove bottom. The fold-back portion is arranged axially along the hinge seat body. The fold-back portion includes a second groove opening that connects with the first groove bottom of the spiral portion and a second groove bottom near the insertion end.

[0009] The shape of the insertion head of the pin is adapted to the shape of the mating groove for axial sliding fit, and the axial limiting member is a pin that passes radially through the insertion head;

[0010] The elastic mechanism includes a slide rod and a first spring. The axial depth of the mating groove is greater than the axial length of the insertion part, and a first sliding hole is provided at the bottom of the groove along the axial direction. One end of the slide rod is inserted into the first sliding hole for axial sliding fit, and a limiting flange is provided at the other end. The first spring is sleeved on the slide rod, and both ends are fixedly connected to the limiting flange and the bottom of the mating groove, respectively.

[0011] When the connector is inserted into the mating groove, the pin enters the spiral part. When the pin enters the fold-back part, it pushes the slide rod and the first spring contracts. The elastic force of the first spring restoring its deformation drives the pin to stay on one side of the bottom of the second groove of the fold-back part.

[0012] The above technical solution is adopted as an embodiment, as shown in the appendix to the specification. Figure 1 , 2 As shown, when the connector is inserted into the mating groove, it rotates deeper along the spiral section. During the process of the connector being inserted, it impacts the limiting flange, causing the slide rod and the first spring to retract. When the pin reaches the bottom of the first groove, the hand action is released, the external force disappears, and the first spring drives the pin to slide along the folded-back section to the bottom of the second groove and presses against the connector, keeping it axially fixed with the hinge seat.

[0013] When disassembly is required, simply reverse the direction of the connector with your hand to quickly disassemble it.

[0014] A further feature of this invention is that the axial limiting groove is a through hole that penetrates the mating groove radially, and the insertion part of the pin is provided with a mounting hole that penetrates radially. When the insertion part is inserted into the mating groove, the position of the mounting hole coincides with the position of the through hole.

[0015] The elastic mechanism is disposed in the mounting hole and includes a central rod, a pair of sliding caps, and a second spring. The pair of sliding caps are symmetrically disposed at the two openings of the mounting hole, and their outer circumferential surfaces are adapted to the mounting hole for axial sliding engagement. The pair of sliding caps includes a ball head extending out of the mounting hole and a connecting part inside the mounting hole. The connecting part has a second sliding hole at its center. The two ends of the central rod are respectively slidably engaged in the second sliding holes of the pair of sliding caps. The second spring is sleeved on the central rod, and its two ends are respectively fixedly connected to the pair of sliding caps. The elastic force of the second spring restoring its deformation drives the sliding caps to extend out of the mounting hole.

[0016] The above technical solution is adopted as Embodiment Two, as shown in the appendix to the specification. Figure 3 , 4 The central rod is fixed to the mounting hole by means of spot welding, fusion welding, setting a slider in the middle section, and setting a groove on the side of the mounting hole. A pair of sliding caps are fixed and limited by the second spring, and slide out and retract into the mounting hole. After the plug part is inserted into the mating groove, the position of the mounting hole coincides with the position of the through hole. The ball head of the sliding cap enters the through hole, forming an axial limit fixation to keep the two connected. When disassembly is required, the user pulls out the plug part, and the sliding cap is retracted into the mounting hole by force.

[0017] A further feature of this invention is that an annular groove is coaxially provided in the docking groove, and the elastic mechanism and axial limiting member are annular members made of elastic material. The annular member is axially fixed to the outer circumferential surface of the plug part. When the plug part is inserted into the docking groove, the annular member elastically engages in the annular groove for axial limiting.

[0018] The above technical solution is adopted as Embodiment 3, as shown in the appendix to the specification. Figure 5 As shown, the annular part of the elastic material deforms under pressure and recovers its deformation on its own when no pressure is applied. When the connector enters the mating groove, the annular part is squeezed and pushed back against the inner wall of the mating groove. When it reaches the annular groove, the expanded space allows the annular part to recover, thereby forming an axial locking limit. When disassembling, the operator can simply pull out the connector in the opposite direction.

[0019] A further feature of this invention is that the housing has an assembly groove that matches the contour of the pin, and a first screw hole that extends through the assembly groove is provided on the end face of the housing facing the wearer's face. A second screw hole is provided on the pin corresponding to the position of the first screw hole, and a screw is screwed into the first screw hole and the second screw hole for axial fixation.

[0020] A further feature of this invention is that the connector portion is provided with a pair of shoulder blades at intervals, and the eyeglasses also include a decorative element that is detachably installed between the pair of shoulder blades.

[0021] A further feature of this invention is that the hinge end of the hinge seat is provided with a rotating groove, a pin hole penetrating the center of the rotating groove, and a pin. One end of the hinge head is fixedly connected to the head of the frame, and the other end is inserted into the rotating groove for selective engagement. The hinge head is coaxially provided with a rotating hole corresponding to the pin hole position, and the pin passes through the rotating hole and is threadedly connected to the pin hole.

[0022] The beneficial effects of this utility model are as follows: This application separates the temple into a hinge base, a pin, and a housing. By utilizing the plug-in structure design of the hinge base and the pin connector, the temple can be quickly plugged in and removed. The wearer does not need to prepare any external tools and can easily replace the temple by hand according to the environmental functional needs and aesthetic requirements. Moreover, the replacement process does not involve the hinge part, thus avoiding disassembly and wear of the hinge part. Attached Figure Description

[0029] To better illustrate this embodiment, some parts in the accompanying drawings may be omitted, enlarged, or reduced, and do not represent the actual size of the product. Furthermore, the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Detailed Implementation

[0030] To make the technical solution and advantages of this application clearer, the technical solution of this application will be described in a clearer and more complete manner below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this application, and are only used to explain this application, not to limit this application. It should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings. Other related parts can be referred to the general design. In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other to obtain new embodiments.

[0031] like Figure 1-5 As shown, an easily replaceable structure for eyeglass temples includes a frame 1, temples 2, hinge heads 3, and hinge seats 4. The hinge seat 4 includes a hinge end and a plug end. The plug end is coaxially provided with a mating groove 41, and an axial limiting groove is provided at the mating groove 41. The temple 2 includes a pin 21 and a housing 23. One end of the pin 21 is provided with a plug portion 22, and the other end is inserted into the housing 23 for a detachable fixed connection. The plug portion 22 is provided with an elastic mechanism and an axial limiting member. The plug portion 22 is inserted into the mating groove 41, and the elastic mechanism drives the axial limiting member to elastically engage with the axial limiting groove.

[0032] The axial limiting groove is a through groove that extends radially into the mating groove 41. The axial limiting groove includes a spiral part 42 and a fold-back part 43. The spiral part 42 extends from the insertion end along the outer peripheral surface toward the hinge end. The spiral part 42 includes a first groove opening and a first groove bottom. The fold-back part 43 is arranged along the axial direction of the hinge seat 4. The fold-back part 43 includes a second groove opening that connects with the first groove bottom of the spiral part 42 and a second groove bottom near the insertion end.

[0033] The shape of the plug portion 22 of the pin 21 is adapted to the shape of the mating groove 41 for axial sliding fit, and the axial limiting member is a pin 43 that radially passes through the plug portion 22.

[0034] The elastic mechanism includes a slide rod 51 and a first spring 52. The axial depth of the mating groove 41 is greater than the axial length of the insertion part 22, and a first sliding hole 411 is provided at the bottom of the groove along the axial direction. One end of the slide rod 51 is inserted into the first sliding hole 411 for axial sliding engagement, and the other end is provided with a limiting flange 511. The first spring 52 is sleeved on the slide rod 51, and both ends are fixedly connected to the limiting flange 511 and the bottom of the mating groove 41, respectively.

[0035] When the connector portion 22 is inserted into the docking groove 41, the pin 43 also enters the spiral portion 42. When the pin 43 enters the fold-back portion 43, the pusher slide 51 and the first spring 52 contract. The elastic force of the first spring 52 restoring its deformation drives the pin 43 to stay on one side of the bottom of the second groove of the fold-back portion 43.

[0036] As an example of embodiment one, see the appendix to the instruction manual. Figure 1 , 2 As shown, when the connector 22 is inserted into the mating groove 41, it rotates and goes deeper along the spiral part 42. During the process of the connector 22 going deeper, it hits the limiting flange 511, causing the slide rod 51 and the first spring 52 to retract. When the pin 43 reaches the bottom of the first groove, the hand action is released, the external force disappears, and the first spring 52 drives the pin 43 to slide along the folded-back part 43 to the bottom of the second groove and presses against the connector 22, keeping it axially fixed with the hinge seat 4.

[0037] When disassembly is required, simply reverse the direction of the connector 22 with your hand to quickly disassemble it.

[0038] The axial limiting groove is a through hole 61 that penetrates the docking groove 41 radially. The insertion part 22 of the pin 21 is provided with a mounting hole 62 that penetrates radially. When the insertion part 22 is inserted into the docking groove 41, the position of the mounting hole 62 coincides with the position of the through hole 61.

[0039] The elastic mechanism is disposed in the mounting hole 62 and includes a central rod 63, a pair of sliding caps 64, and a second spring 65. The pair of sliding caps 64 are symmetrically disposed at the two openings of the mounting hole 62, and their outer peripheral surfaces are adapted to the mounting hole 62 for axial sliding engagement. The pair of sliding caps 64 includes a ball head that extends out of the mounting hole 62 and a connecting part inside the mounting hole 62. The connecting part has a second sliding hole at its center. The two ends of the central rod 63 are respectively slidably engaged in the second sliding holes of the pair of sliding caps 64. The second spring 65 is sleeved on the central rod 63, and its two ends are respectively fixedly connected to the pair of sliding caps 64. The elastic force of the second spring 65 in restoring its deformation drives the sliding caps 64 to extend out of the mounting hole 62.

[0040] As an example two, see the appendix to the instruction manual. Figure 3 , 4 The central rod 63 is fixed to the mounting hole 62 by means such as spot welding, fusion welding, setting a slider in the middle section, and setting a groove on the side of the mounting hole 62. A pair of sliding caps 64 are fixed and limited by the second spring 65, and slide out and retract into the mounting hole 62. After the plug part 22 is inserted into the mating groove 41, the position of the mounting hole 62 coincides with the position of the through hole 61. The ball head of the sliding cap 64 enters the through hole 61, forming an axial limit fixation to keep the two connected. When disassembly is required, the user pulls out the plug part 22, and the sliding cap 64 is retracted into the mounting hole 62 by force.

[0041] An annular groove 71 is coaxially provided in the docking groove 41. The elastic mechanism and axial limiting member are annular members 72 made of elastic material. The annular members 72 are axially fixed to the outer circumferential surface of the plug part 22. When the plug part 22 is inserted into the docking groove 41, the annular members 72 are elastically inserted into the annular groove 71 for axial limiting.

[0042] As an example three, see the appendix to the instruction manual. Figure 5 As shown, the annular part 72, made of elastic material, deforms under pressure and recovers its deformation on its own when there is no pressure. The connector part 22 enters the mating groove 41, causing the annular part 72 to be squeezed and pushed back against the inner wall of the mating groove 41. When it reaches the annular groove 71, the expanded space allows the annular part 72 to recover, thereby forming an axial locking limit. When disassembling, the operator can pull out the connector part 22 in the opposite direction.

[0043] The housing 23 is provided with an assembly groove that matches the contour of the pin 21. The end face of the housing 23 facing the wearer's face is provided with a first screw hole 81 that extends through the assembly groove. The pin 21 is provided with a second screw hole 82 corresponding to the position of the first screw hole 81, and a screw is screwed into the first screw hole 81 and the second screw hole 82 for axial fixation.

[0044] The connector portion 22 is provided with a pair of shoulder blades at intervals, and the glasses also include a decorative piece 9, which is detachably installed between the pair of shoulder blades.

[0045] The hinge end of the hinge seat is provided with a rotating groove 44, a pin hole 45 passing through the center of the rotating groove 44, and a pin. One end of the hinge head 3 is fixedly connected to the head of the frame 1, and the other end is inserted into the rotating groove 44 for selective engagement. The hinge head 3 is coaxially provided with a rotating hole corresponding to the position of the pin hole 45, and the pin passes through the rotating hole and is threadedly connected to the pin hole 45.

[0046] This application separates the temple 2 into a hinge base 4, a pin 21, and a housing 23. By utilizing the insertion structure design of the hinge base 4 and the pin 21 into the connector 22, the temple 2 can be quickly inserted and removed. The wearer does not need to prepare any external tools and can easily replace the temple 2 by hand according to the functional needs of the environment and the matching of aesthetic elements. Moreover, the replacement process does not involve the hinge part, thus avoiding disassembly and wear of the hinge part.
