Description

Technical Field

[0001] The utility model belongs to the technical field of glasses and relates to a positioning connection structure of glasses temple arms. Background Art

[0002] Glasses are composed of lenses and frames. In traditional glasses, the frame and the temple arms are generally connected by hinges. The temple arms connected by hinges are not convenient to disassemble and replace. At the same time, there is generally a rotating shaft inserted between the hinge and the frame, and then limit rings are fixed at both ends of the rotating shaft, which is not convenient for the assembly of the hinge and the frame. In view of this situation, there appears a kind of glasses with convenient replacement of temple arms in the market, such as a kind of glasses with convenient replacement of temple arms described in Chinese Patent No. "202221241798.5". The specific structure of this kind of glasses is as follows: It includes a frame, temple arms and a connecting piece. Lenses are fixedly installed inside the frame. Fixed blocks are fixedly provided at both corners on one side of the frame. A connecting piece is rotatably connected between the two fixed blocks. A connecting mechanism is arranged between the connecting piece and the fixed blocks. A connecting block integrally connected is fixedly provided on the side of the connecting piece. A connecting groove is opened at the end of the temple arm. The connecting block is embedded and connected with the connecting groove. Card holes are opened on both sides of the connecting groove. A groove is opened at the top of the connecting block. Wedge-shaped clamping blocks are inserted and connected on both sides of the groove. The two wedge-shaped clamping blocks are clamped and connected with the corresponding card holes. Fixing plates are fixedly installed on one side of the two wedge-shaped clamping blocks. A compression spring is fixedly installed between the two fixing plates. When the temple arms need to be replaced, first, manually squeeze the middle of the wedge-shaped clamping blocks to separate the wedge-shaped clamping blocks from the card holes. Then, manually pull the temple arms outwards to separate the connecting block from the connecting groove, completing the disassembly of the temple arms. Then, embed the connecting groove provided at the end of the new temple arm with the connecting block again, and through the compression spring, squeeze the wedge-shaped clamping blocks to be embedded with the card holes, completing the replacement of the temple arms.

[0003] In the above structure, the connecting piece and the fixed block are hinged by a limiting post, enabling the temple arms to rotate relative to the frame. However, there is no positioning limit during the rotation process of the temple arms, resulting in the temple arms being unable to be positioned in the open state and the closed state. The temple arms often rotate automatically due to gravity and other reasons during movement, affecting the use. For example, when the user needs to wear glasses with one hand, after spreading the two temple arms, the temple arms often rotate automatically to the closed state during the movement, making it impossible to wear. At the same time, when disassembling the temple arms, it is necessary to manually squeeze the two wedge-shaped clamping blocks towards the middle simultaneously, so that the two wedge-shaped clamping blocks are separated from the card holes at the same time. Since the structure of the wedge-shaped clamping blocks is small, it is difficult to apply force during extrusion, and tools often need to be used to press the two wedge-shaped clamping blocks inward at the same time. The above disassembly process is troublesome and very laborious. Summary of the Invention

[0004] The purpose of the utility model is to provide a positioning connection structure of glasses temple arms that can conveniently position the temple arm body in the open state or the closed state for the above problems existing in the prior art.

[0005] The object of the present utility model can be achieved by the following technical solutions: A positioning connection structure for spectacle temple pieces, comprising a movable block, a spring, a first fixing block located at both ends of the spectacle frame, and a second fixing block located at the end of the temple piece body. The movable block is slidably arranged on the second fixing block. Both ends of the spring are respectively in contact with the movable block and the second fixing block. A fixing convex block is provided on the first fixing block, and the fixing convex block is hinged to the end of the second fixing block. The movable block is located between the first fixing block and the second fixing block, and the elastic force of the spring makes the movable block in contact with the first fixing block. When the temple piece body and the second fixing block drive the movable block to rotate, the movable block is squeezed by the fixing convex block and moves away from the first fixing block, so that the spring is compressed; when the temple piece body rotates to the open state or the closed state, the elastic force of the spring is released to drive the movable block to reset and contact the first fixing block again.

[0006] In the above-mentioned positioning connection structure for spectacle temple pieces, an arc-shaped connection groove is formed on the first fixing block, the fixing convex block is located in the middle of the connection groove, a first fixing hole is formed on the fixing convex block, insertion grooves are formed by concave portions on both side surfaces of the movable block, the movable block is integrally in an I-shaped structure, a spring groove is formed in the middle of the movable block, the spring is located in the spring groove, and two oppositely arranged fixing rods are formed on the second fixing block, and second fixing holes and threaded holes are respectively formed at the ends of the two fixing rods.

[0007] In the above-mentioned positioning connection structure for spectacle temple pieces, the two fixing rods are respectively inserted into the two insertion grooves, so that the second fixing hole and the threaded hole are both exposed from the insertion grooves; the fixing convex block is inserted between the two fixing rods, a fixing screw is provided on the second fixing block, and the end of the fixing screw sequentially passes through the second fixing hole, the first fixing hole and is fixed in the threaded hole, completing the hinge connection between the second fixing block and the first fixing block, and at the same time completing the hinge connection between the temple piece body and the spectacle frame.

[0008] In the above-mentioned positioning connection structure for spectacle temple pieces, a first limiting plate is formed by extending one side surface of the movable block, and a second limiting plate is formed by extending the side surface of the first fixing block. When the temple piece body is in the open state, the end surface of the first limiting plate is in close contact with the end surface of the second limiting plate.

[0009] In the above positioning and connecting structure of the spectacle temple, the fixed bump includes a first contact surface, and second contact surfaces and guiding surfaces located at both ends of the first contact surface. An extrusion angle is formed between the first contact surface and the second contact surfaces. When the temple body rotates, the extrusion angle extrudes the movable block; when the temple body is in the closed state, the end surface of the movable block contacts the second contact surface, and the guiding surface is arc-shaped.

[0010] In the above positioning and connecting structure of the spectacle temple, bending portions are provided at both ends of the spectacle frame, and the first fixing block is connected to the end of the bending portion.

[0011] In the above positioning and connecting structure of the spectacle temple, a first installation groove and a first inclined surface are respectively formed on both side surfaces of the first fixing block, the end of the bending portion is fixed in the first installation groove, a second installation groove and a second inclined surface are respectively formed on both side surfaces of the second fixing block, and the end of the temple body is fixed in the second installation groove.

[0012] In the above positioning and connecting structure of the spectacle temple, a first insertion bump is formed at the end of the second fixing block, a first installation groove is formed at the end of the temple body, the first insertion bump is inserted into the first installation groove, and a first screw fixes the temple body and the first insertion bump to complete the connection between the second fixing block and the temple body.

[0013] In the above positioning and connecting structure of the spectacle temple, the first fixing block, the bending portion and the spectacle frame are integrally formed.

[0014] In the above positioning and connecting structure of the spectacle temple, a second insertion bump is formed at the end of the first fixing block, a second installation groove is formed at the end of the spectacle frame, the second insertion bump is inserted into the second installation groove, and a second screw fixes the spectacle frame and the second insertion bump to complete the connection between the first fixing block and the spectacle frame.

[0015] In the above positioning and connecting structure of the spectacle temple, an embedding block is formed at the end of the first fixing block. The first fixing block is made of metal, and the spectacle frame is made of plastic. The spectacle frame is injection-molded by an injection mold. The embedding block is located in the mold cavity of the injection mold, so that the embedding block is embedded into the bending portion during the injection molding process of the spectacle frame to complete the fixation of the first fixing block and the spectacle frame.

[0016] Compared with the prior art, in the positioning and connecting structure of the spectacle temple of the present invention, when the temple body rotates, the fixed bump presses the movable block and the spring is compressed. That is, when the temple body rotates, it is necessary to overcome the elastic force of the spring to compress the spring. Therefore, the rotation of the temple body must be achieved by manual force to prevent the temple body from automatically rotating due to natural factors such as gravity, which may affect wearing and use. At the same time, when the temple body rotates to the open state or the closed state, the elastic force of the spring is released, which facilitates positioning the temple body in the open state or the closed state. When the temple body is in the open state, the end face of the first limiting plate is in close contact with the end face of the second limiting plate. At this time, the second fixing block and the temple body cannot rotate outward any further, restricting the rotation range of the temple body and facilitating positioning the temple body in the open state. The arc-shaped guiding surface guides the rotation process of the first fixing block relative to the movable block, making the rotation smoother and preventing interference and jamming. Loosening the fixing screw can complete the connection between the second fixing block and the first fixing block, realizing the disassembly between the spectacle frame and the temple body. The installation and disassembly are simple and convenient, facilitating maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] The following are specific embodiments of the present invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0029] Embodiment 1:

[0030] As Figures 1-6 shown, the positioning and connecting structure of the temple of this pair of glasses includes a movable block 5, a spring 6, first fixing blocks 3 located at both ends of the spectacle frame 1, and second fixing blocks 4 located at the ends of the temple body 2. The movable block 5 is slidably arranged on the second fixing block 4, and both ends of the spring 6 are in contact with the movable block 5 and the second fixing block 4 respectively. The first fixing block 3 is provided with a fixing convex block 32, and the fixing convex block 32 is hinged to the end of the second fixing block 4. The movable block 5 is located between the first fixing block 3 and the second fixing block 4, and the elastic force of the spring 6 makes the movable block 5 contact with the first fixing block 3. When the temple body 2 and the second fixing block 4 drive the movable block 5 to rotate, the movable block 5 is squeezed by the fixing convex block 32 and moves away from the first fixing block 3, so that the spring 6 is compressed; when the temple body 2 rotates to the open state or the closed state, the elastic force of the spring 6 is released to drive the movable block 5 to reset to contact with the first fixing block 3.

[0031] In the above technical solution: a first limiting plate 53 is formed by extending one side surface of the movable block 5, and a second limiting plate 37 is formed by extending the side surface of the first fixing block 3. When the temple body 2 is in the open state, the end face of the first limiting plate 53 is in close contact with the end face of the second limiting plate 37. As Figure 3 shown, at this time, the second fixing block 4 and the temple body 2 cannot rotate outward any further, restricting the rotation range of the temple body 2, and at the same time facilitating positioning the temple body 2 in the open state.

[0032] In the above technical solution, the fixed bump 32 includes a first contact surface 34, and second contact surfaces 35 and guiding surfaces 38 located at both ends of the first contact surface 34. An extrusion angle 36 is formed between the first contact surface 34 and the second contact surfaces 35. When the temple body 2 rotates, the extrusion angle 36 extrudes the movable block 5; when the temple body 2 is in the closed state, the end surface 54 of the movable block 5 is in contact with the second contact surface 35. The guiding surface 38 is arc-shaped, and the guiding surface 38 guides the rotation process of the first fixing block 3 relative to the movable block 5, making the rotation smoother and preventing interference and jamming.

Insertion grooves 51 are formed by concave portions on both side surfaces of the movable block 5. The movable block 5 is integrally in an I shape, and a spring groove 52 is formed in the middle of the movable block 5. The spring 6 is located in the spring groove 52. Two relatively arranged fixing rods 41 are formed on the second fixing block 4, and second fixing holes 42 and threaded holes 43 are respectively formed at the ends of the two fixing rods 41.

[0034] The two fixing rods 41 are respectively inserted into the two insertion grooves 51. At this time, both ends of the spring 6 are in contact with the bottom of the spring groove 52 and the second fixing block 4 respectively. The movable block 5 is extruded to compress the spring 6 until both the second fixing hole 42 and the threaded hole 43 are exposed from the insertion grooves 51; then the fixed bump 32 is inserted between the two fixing rods 41. A fixing screw 7 is provided on the second fixing block 4. The end of the fixing screw 7 sequentially passes through the second fixing hole 42 and the first fixing hole 33 and is fixed in the threaded hole 43, completing the hinged connection between the second fixing block 4 and the first fixing block 3, and also completing the hinged connection between the temple body 2 and the spectacle frame 1. After the fixing screw 7 is tightened and fixed, the extrusion of the movable block 5 is stopped, and the elastic force of the spring 6 is released to make the movable block 5 in contact with the first fixing block 3.

[0035] In the above technical solution: bending portions 11 are provided at both ends of the spectacle frame 1, and the first fixing block 3 is connected to the end of the bending portion 11. In this embodiment, the bending portion 11 and the spectacle frame 1 are integrally formed. In this embodiment, first mounting grooves 39 and first inclined surfaces 310 are respectively formed on both side surfaces of the first fixing block 3, and the end of the bending portion 11 is fixed in the first mounting groove 39. The specific fixing method can be adhesive fixing, screw fixing or welding fixing, etc. Second mounting grooves 44 and second inclined surfaces 45 are respectively formed on both side surfaces of the second fixing block 4, and the end of the temple body 2 is fixed in the second mounting groove 44. The specific fixing method can be adhesive fixing, screw fixing or welding fixing, etc. When the glasses are worn, the first inclined surface 310 and the second inclined surface 45 are close to the human face, making the wearing more comfortable.

[0036] Embodiment Two:

[0037] This embodiment is generally similar to Embodiment 1 in terms of the technical solution. Only the different parts will be described in detail, and the same content between the two will not be elaborated here.

[0038] As Figure 7 shown, in this embodiment, the first fixing block 3 is integrally formed with the bending portion 11 and the lens frame 1. Figure 7 Only a part of the bending portion 11 is shown in the figure. A first insertion convex block 46 is formed at the end of the second fixing block 4, and a first installation groove is formed at the end of the temple body 2. The first insertion convex block 46 is inserted into the first installation groove, and a first screw fixes the temple body 2 and the first insertion convex block 46 to complete the connection between the second fixing block 4 and the temple body 2.

[0039] Embodiment 3:

[0040] This embodiment is generally similar to Embodiment 1 in terms of the technical solution. Only the different parts will be described in detail, and the same content between the two will not be elaborated here.

[0041] As Figure 8 shown, in this embodiment, a second insertion convex block 311 is formed at the end of the first fixing block 3, and a second installation groove is formed at the end of the bending portion 11. The second insertion convex block 311 is inserted into the second installation groove, and a second screw fixes the bending portion 11 and the second insertion convex block 311 to complete the connection between the first fixing block 3 and the lens frame 1. The connection manner between the second fixing block 4 and the temple body 2 in this embodiment is the same as that in Embodiment 2.

[0042] Embodiment 4:

[0043] This embodiment is generally similar to Embodiment 1 in terms of the technical solution. Only the different parts will be described in detail, and the same content between the two will not be elaborated here.

[0044] As Figure 9 shown, in this embodiment, an embedding block 312 is formed at the end of the first fixing block 3. The first fixing block 3 is made of metal, and the lens frame 1 is made of plastic. The lens frame 1 is injection-molded by an injection mold. The embedding block 312 is located in the cavity of the injection mold, so that the embedding block 312 is embedded into the bending portion 11 during the injection molding process of the lens frame 1 to complete the fixation of the first fixing block 3 and the lens frame 1. The connection manner between the second fixing block 4 and the temple body 2 in this embodiment is the same as that in Embodiment 2.

[0045] Embodiment 5:

[0046] This embodiment is generally similar to Embodiment 1 in terms of the technical solution. Only the different parts will be described in detail, and the same content between the two will not be elaborated here.

[0047] As Figure 10As shown, in this embodiment, the bent portion 11 and the first fixing block 3 are integrally formed, and the end of the bent portion 11 is fixed to the end of the spectacle frame 1 by fasteners such as screws. In this embodiment, the connection manner between the second fixing block 4 and the spectacle leg body 2 is the same as that in the second embodiment.

[0048] In the positioning and connecting structure of the spectacle leg of this pair of glasses, when the spectacle leg body 2 rotates, the fixed convex block 32 presses the movable block 5, and the spring 6 is compressed. That is, when the spectacle leg body 2 rotates, it must overcome the elastic force of the spring 6 to compress the spring 6. Therefore, the rotation of the spectacle leg body 2 must be manually applied to prevent the spectacle leg body 2 from automatically rotating due to natural factors such as gravity, which may affect wearing and use. At the same time, when the spectacle leg body 2 rotates to the open state or the closed state, the elastic force of the spring 6 is released, which is convenient to position the spectacle leg body 2 in the open state or the closed state. When the spectacle leg body 2 is in the open state, the end face of the first limiting plate 53 is in close contact with the end face of the second limiting plate 37. At this time, the second fixing block 4 and the spectacle leg body 2 cannot rotate outward any further, restricting the rotation range of the spectacle leg body 2 and at the same time facilitating positioning the spectacle leg body 2 in the open state. The arc-shaped guiding surface 38 guides the rotation process of the first fixing block 3 relative to the movable block 5, making the rotation smoother and preventing interference and jamming. Loosening the fixing screw 7 can complete the connection between the second fixing block 4 and the first fixing block 3, realizing the disassembly between the spectacle frame 1 and the spectacle leg body 2. The installation and disassembly are simple and convenient, facilitating maintenance.
