Description

Technical Field

[0001] The utility model relates to the technical field of spectacle frames, in particular to the technical field of spectacle temples. Background Art

[0002] Glasses are composed of lenses and frames, and are used to improve eyesight, protect eyes or for decorative purposes. Glasses can correct various vision problems, including myopia, hyperopia, astigmatism, presbyopia, strabismus or amblyopia, etc.

[0003] The spectacle frame is composed of temples and a frame. The temples and the frame are both split assembly structures. For example, in Chinese Patent CN102269878A, in order to realize the opening and closing of the temples, a hinge connection method is adopted. The temples can rotate around the frame with the hinge as the fulcrum to realize opening and closing. Such a hinge connection structure requires the installation of small screws. During the use of glasses, the temples or the frame are often easily damaged separately. In this case, the wearer basically needs to directly replace a new pair of glasses, resulting in waste and increased costs. In particular, the undamaged temples or frames cannot be used and need to be scrapped as a whole. Moreover, since the assembly of the two requires professional tools, ordinary wearers cannot repair the components.

[0004] In addition, Chinese Patent CN202548450U cancels the locking screws at the joint of the frame and improves the structure to be connected by a stud and a connection box. The connection box includes a bottom plate, a cover plate, an insertion plate, etc. Although such a structure cancels the locking screws at the joint of the frame, the connection between the temple and the connection box still uses a bolt connection, only the connection position is transferred, and it does not really achieve convenient disassembly. Moreover, the structure is more complex, adding multiple components between the temple and the frame, and the assembly efficiency is lower. It not only cannot directly replace the frame and the temple as single components, but also requires tools such as a screwdriver to disassemble and install, with low repair efficiency and inconvenient replacement. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems in the prior art, and propose a temple with a spiral installation structure and a spectacle frame using such a temple, which can directly disassemble the temple and the frame without the need for any tools, and quickly and conveniently replace components.

[0006] To achieve the above purpose, the utility model proposes a temple with a spiral installation structure, including a temple body. A limiting part is provided at the front end of the temple body, and a second spiral structure that can be cooperatively installed with a first spiral structure on the frame body extends laterally from the limiting part.

[0007] Preferably, the limiting part is linear, and the second spiral structure is a spiral shape that bends inwardly into the temple body, and the spiral length is greater than one circumferential length.

[0008] To achieve the above object, the present utility model further provides a spectacle frame, which includes a spectacle frame body and temple arms with a spiral mounting structure. Both ends of the spectacle frame body are provided with a first spiral structure, and a limiting portion is provided at the front end of the temple arm body. The limiting portion extends laterally with a second spiral structure that can be fitted and mounted with the first spiral structure on the spectacle frame body. The different shapes of the limiting portion and the first spiral structure realize the defined fixation.

[0009] Preferably, the first spiral structure is a hollow spiral tube provided with a spiral hole, and the second spiral structure is a spiral column having the same spiral direction as that of the spiral hole. The outer diameter of the spiral column is smaller than the diameter of the spiral hole.

[0010] Preferably, the limiting portion is linear, and the second spiral structure is a spiral column bent inwardly of the temple arm body. The length of the spiral column is greater than one circumferential length. The spiral column can be screwed into or out of the spiral hole, and the limiting portion cannot be screwed into the spiral hole, thereby realizing the fixed structure when the spiral column is completely screwed into the spiral hole.

[0011] Preferably, the limiting portion is a variable diameter structure, with the front end diameter smaller than the rear end diameter, and the diameter of the foremost end smaller than the diameter of the spiral hole, and the diameter of the rearmost end greater than the diameter of the spiral hole.

[0012] Preferably, the limiting portion is linear, the front end of the hollow spiral tube is connected to the spectacle frame body, and the end of the hollow spiral tube opens backward. After the temple arm body and the spectacle frame body are assembled, the direction of the limiting portion on the temple arm body is consistent with the opening direction of the end of the hollow spiral tube.

[0013] Preferably, the second spiral structure is a hollow spiral tube provided with a spiral hole, and the first spiral structure is a spiral column having the same spiral direction as that of the spiral hole. The outer diameter of the spiral column is smaller than the diameter of the spiral hole.

[0014] The beneficial effects of the present utility model: The present utility model realizes the disassembly and assembly between the two through the first spiral structure and the second spiral structure respectively provided on the spectacle frame body and the temple arm body by manual operation. After the temple arm body is screwed into the spectacle frame body for one or more turns, the limiting portion cannot be screwed into the spectacle frame body to realize the fixation. By rotating the temple arm body in the opposite direction, the second spiral structure can be screwed out of the first spiral structure to realize the complete separation and replacement of the two. The entire disassembly process does not require any tools, and the wearer can replace the damaged part by purchasing a single part and continue to use it, which not only solves the problem of resource waste, but also greatly reduces the replacement cost of the spectacle wearer.

[0015] The features and advantages of the present utility model will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiment 1:

[0019] Refer to Figure 1 、 Figure 2 , the spectacle frame includes a frame body 4 and a temple body 1 with a spiral mounting structure. Both ends of the frame body 4 are provided with a first spiral structure 5. The front end of the temple body 1 is provided with a limiting portion 2. The limiting portion 2 extends laterally with a second spiral structure 3 that can be cooperatively mounted with the first spiral structure 5 on the frame body 4. The shapes of the limiting portion 2 and the first spiral structure 5 are different to achieve defined fixation.

[0020] In this embodiment, the first spiral structure 5 is a hollow spiral tube provided with a spiral hole 6. The second spiral structure 3 is a spiral column with the same spiral direction as that of the spiral hole 6. The outer diameter of the spiral column is smaller than the diameter of the spiral hole 6. It is sufficient that the outer diameter of the spiral column is 0.1 - 0.5 millimeters smaller than the diameter of the spiral hole 6. If it is too small, it may affect the stability during connection. Of course, when a small part of the limiting portion 2 is inserted into the spiral hole 6, fixation is achieved. Under the condition of precise processing technology, it is sufficient to be 0.1 millimeter smaller for stable cooperative mounting. Under the condition of inaccurate processing technology, it is preferably reduced to about 0.3 millimeters as much as possible, and then the fixation is achieved by increasing the size of the limiting portion 2 to be equal to the size of the spiral hole 6. The limiting portion 2 can adopt a variable diameter structure, with the front end diameter smaller than the rear end diameter, the diameter of the foremost end smaller than the diameter of the spiral hole 6, and the diameter of the rearmost end larger than the diameter of the spiral hole 6, achieving the effect of getting tighter and tighter with the spiral hole 6 during rotation. The limiting portion 2 is linear. The second spiral structure 3 is a spiral column bent towards the inner side of the temple body 1. The length of the spiral column is greater than one circumferential length. The spiral column can be screwed into or out of the spiral hole 6. The limiting portion 2 cannot be screwed into the spiral hole 6, thus achieving the fixation structure when the spiral column is completely screwed into the spiral hole 6. The limiting portion 2 is linear. The front end of the hollow spiral tube is connected to the frame body 4. The end of the hollow spiral tube opens backward. After the temple body 1 and the frame body 4 are assembled, the direction of the limiting portion 2 on the temple body 1 is consistent with the opening direction of the end of the hollow spiral tube. The cooperation structure of the hollow spiral tube and the spiral column is simple. When the spiral column is screwed into the hollow spiral tube, the phenomenon of non-detachment occurs under force from all angles. The spiral bent shape enables their cooperative mounting, while the linear limiting portion 2 cannot be screwed into the hollow spiral tube, achieving stable fixation. As a variation, as long as the hole shape of the limiting portion 2 is inconsistent with that of the spiral hole 6, it can be achieved that the limiting portion 2 cannot be rotationally inserted into the spiral hole 6, thereby achieving the purpose of fixation.

[0021] In this embodiment, the limiting portion 2 is linear, and the second spiral structure 3 is a spiral shape that bends inward toward the temple body 1. The spiral length is one circumferential length. Using one circumferential length can exactly achieve one full rotation to make the frame body 4 perpendicular to the temple body 1, and the temple body 1 faces the rear side. A stable connection is achieved by the way that the limiting portion 2 cannot be screwed into the first spiral structure 5. When worn, the second spiral structure 3 is completely screwed into the first spiral structure 5, and there will be no relative movement, enabling stable wearing. When any one of the components needs to be replaced, just rotate in the opposite direction and completely screw the second spiral structure 3 out of the first spiral structure 5, and the disassembly of the two is directly achieved without the need to use any tools, and the structure itself is very simple and the cost is low.

[0022] Embodiment Two:

[0023] In this embodiment, the second spiral structure 3 is a hollow spiral tube provided with a spiral hole 6, and the first spiral structure 5 is a spiral column with the same spiral direction as the spiral hole 6. The outer diameter of the spiral column is smaller than the diameter of the spiral hole 6, that is: compared with Embodiment One, the positions of the hollow spiral tube and the spiral column are interchanged. The hollow spiral tube is on the temple body 1, and the spiral column is on the frame body 4, and the spiral fixation is also achieved, and the purpose of being stable and not detaching under force from all angles is achieved.

[0024] Embodiment Three:

[0025] In this embodiment, the limiting portion 2 is linear, and the second spiral structure 3 is a spiral shape that bends inward toward the temple body 1. The spiral length is two circumferential lengths. To achieve a stable connection, one circumferential length can achieve it. Of course, using two circumferential lengths or three circumferential lengths and longer lengths will be more firmly combined, but too long a length will lead to a complex structure, heavy weight, high cost, and also not beautiful.

[0026] The above embodiments are descriptions of the present invention, not limitations on the present invention. Any solution obtained by simply changing the present invention belongs to the protection scope of the present invention.
