Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a quick-detachable connection structure of a glasses frame and glasses legs. Background Art

[0002] At present, glasses are composed of frames and temples, and a large number of small screws or small pins are installed at the connection between the frame and the temples to connect the temples and the frame. In the daily production of glasses manufacturers, the frame and the temples are usually produced separately, and then the frame and the temples are connected by small screws or small pins, but the number of screws or pins required is too large, resulting in the entire assembly process being cumbersome and time-consuming, thereby reducing the production efficiency of glasses products. At the same time, the use of too many parts leads to an increase in production costs and assembly costs. In the daily use of glasses by users, the connection between the temples and the frame is damaged and broken due to external stress impact or bumps, so that users need to send them to the glasses store for temple replacement, but there are fewer suitable temples and the replacement time is long, so that users need to wait for a certain time before wearing glasses, and it is troublesome for users to replace the temples themselves, so that users cannot wear glasses for a long time, and are more restricted in daily life. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a quick disassembly and assembly connection structure between a frame and temples, in order to solve the problem in the prior art that the frame and temples are inconvenient to disassemble and assemble and require a large number of parts such as bolts or pins.

[0004] To achieve the above-mentioned purpose, the utility model provides a quick-detachable connection structure for a frame and a temple, comprising a frame and a temple, wherein a hook and a hook column that are hooked and matched with each other are arranged between the frame and the temple, wherein any one of the hook and the hook column is arranged on the frame, and the other is arranged on the temple, wherein the hook is provided with a rotating groove for the hook column to rotate and a groove for guiding the hook column to be placed into the rotating groove, and a limiting spring piece for pressing the hook column to be kept in the rotating groove is arranged on the frame or the temple.

[0005] The advantages of adopting the above technical scheme are: in the above technology, the frame and the temple are hooked and matched with a hook and a hook column, and the hook and the hook column are respectively arranged on the temple and the frame, that is, if the hook is arranged on the temple, the hook column is arranged on the frame, and if the hook is arranged on the frame, the hook column is arranged on the temple, so as to meet different production conditions and actual use requirements, and through the hook-connection cooperation of the hook and the hook column, that is, the plug-in cooperation of the hook column and the rotating groove, the temple and the frame can be quickly connected, thereby improving the assembly efficiency of the glasses, and the setting of the limiting spring sheet is used to keep the hook column pressed and kept in the rotating groove at all times, at which time the hook column is difficult to escape from the rotating groove to the slot, and the limiting spring sheet has elastic properties so that when the limiting spring sheet is affected by external force, the hook column is no longer kept in the rotating groove due to its own elastic properties, that is, the hook column can escape from the hook along the slot from the rotating groove, thereby realizing the separation of the hook and the hook column, thereby realizing the separation of the temple and the frame, thereby improving the disassembly and assembly efficiency.

[0006] The utility model is further configured as follows: the hook is composed of a connecting portion for connecting to a temple or a frame and a bent portion for hooking and cooperating with a hook column; the limiting spring piece is provided with a through groove for accommodating the connecting portion; a matching block is provided on the temple or the frame; the matching block is provided with a swinging groove for inserting the bent portion of the hook; the hook column is provided in the swinging groove; the starting end of the limiting spring piece is bent toward the matching block and is formed with a bent end for abutting and cooperating with the matching block; the end of the limiting spring piece is a connecting end for connecting to the temple or the frame.

[0007] The advantages of adopting the above technical solution are as follows: taking the example of the hook connection part being installed on the temple and the matching block being installed on the frame, before the hook and the hook column are hooked and matched, the installer presses the bent end of the limiting spring piece so that the inner wall surface of the bent end of the limiting spring piece fits with the inner wall of the temple, and the installer makes the temple and the frame approximately parallel to each other. At this time, the installer moves the temple horizontally so that the hook is gradually placed in the swing groove and the hook column gradually approaches the slot opening. The slot is opened in a direction approximately parallel to the temple, and then the installer continues to move the temple so that the hook column is inserted into the temple. The rim of the eyeglass frame is moved into the groove and into the rotating groove along the groove. After that, the installer no longer presses the bent end of the limiting spring piece, so that the bent end of the limiting spring piece is elastically reset and abuts against the matching block, that is, the limiting spring piece applies a certain force to the matching block, and when the force is applied, a reaction force is generated between the hook connection part and the matching block. The reaction force and the action force make the hook connection part relatively away from the matching block, that is, the hook column gradually moves toward the deepest part of the rotating groove and because of the setting of the limiting spring piece, the hook column is always pressed tightly in the rotating groove, when the temple and the frame are approximately parallel. When the glasses are in the closed state, that is, when the glasses are in the closed state, the limiting spring piece of the hook column is limited in the rotation groove and cannot pass through the rotation groove, so that the hook column can only rotate in the rotation groove, and when it is necessary to separate the temple and the frame, the bent end of the limiting spring piece is pressed so that it no longer applies force to the matching block, and at this time, the temple is pushed toward the direction of the frame so that the hook column relatively escapes from the rotation groove to the slot, and the opening direction of the slot is approximately parallel to the temple, so that horizontal movement of the temple can drive the hook column to move relatively along the slot direction until it escapes from the slot, thereby realizing the separation of the hook and the hook column, and then realizing the separation of the glasses. The legs are separated from the frame; and when the legs and the frame are in an approximately vertical state, that is, when the glasses are in an open state, the bent portion of the hook is affected by the inner wall of the frame, so that when the hook post is in the slot, it is difficult for the hook post to move relatively along the direction of the slot, which makes it difficult for the hook post to separate from the hook, thereby achieving a stable connection between the frame and the legs; in the above-mentioned technology, the limiting spring sheet is provided with a through groove for accommodating the connecting portion, and if the hook is provided on the legs, the limiting spring sheet is also provided on the legs, so that the limiting spring sheet can stably cooperate with the matching block to achieve the limiting of the hook post in the rotating groove.

[0008] The utility model is further provided that: a retaining edge is provided on the outer peripheral wall of the matching block, the outer wall surface of the retaining edge is provided in an arc surface, and the outer wall surface of the bent end of the limiting spring piece is provided in contact with the outer wall surface of the retaining edge.

[0009] The benefit of adopting the above technical solution is that the setting of the retaining edge in the above technology enables the limiting spring sheet to abut against the retaining edge when the glasses are in an open or closed state, thereby achieving stable application of force to the matching block by the limiting spring sheet and stable compression of the hook column in the rotating groove.

[0010] The utility model is further configured that: the direction of the opening of the rotating groove is staggered with the direction of the opening of the slot, and the direction of the opening of the rotating groove is set towards the direction of the hook connecting part.

[0011] The advantages of adopting the above technical solution are that: in the above technology, the direction of the opening of the rotating groove is staggered with the direction of the opening of the slot, and the direction of the opening of the rotating groove is set in the direction of the hook connecting part, so that the hook column is not easy to fall out of the rotating groove when the glasses are in the open or closed state, thereby improving the stable connection between the frame and the temples.

[0012] The utility model is further provided with: a first limiting portion protruding from the hook connecting portion toward the hook bending portion, a clearance fit between the first limiting portion and the hook bending portion forms a release opening, the release opening is connected to the slot, the direction of the release opening is staggered with the direction of the slot opening, and a second limiting portion protruding from the inner wall of the hook bending portion toward the opening of the rotating groove.

[0013] The advantages of adopting the above technical solution are: the setting of the first limiting portion and the release mouth in the above technology makes it difficult for the hook post to fall out of the rotating groove when the glasses are in an open or closed state, thereby improving the stable connection between the frame and the temples, and the setting of the second limiting portion improves the stability of the hook post in the rotating groove, that is, the protrusion setting of the second limiting portion shortens the width of the rotating groove opening in disguised form, so that the hook post is not easy to fall out of the rotating groove during daily use of the glasses, thereby avoiding the separation of the frame and the temples during daily use.

[0014] The utility model is further configured that: the limiting spring piece is made of a metal elastic material.

[0015] The benefits of adopting the above technical solution are: in the above technology, the limiting spring is made of a metal elastic material, so that it has excellent elastic properties and a long service life, and at the same time it is not easy to be damaged or broken, and the use of the limiting spring has excellent elastic reset ability and rapid response ability. Based on the performance of the metal elastic material, the limiting spring is lightweight, thereby reducing the weight of the glasses. In order to reduce the scratches of the limiting spring on the user, a flexible material can be wrapped on the limiting spring to reduce the impact on the user. BRIEF DESCRIPTION OF THE DRAWINGS
