Description

Technical Field

[0001] The utility model relates to a hinge structure, in particular to a hinge structure used for glasses, belonging to the technical field of glasses. Background Art

[0002] Glasses are composed of lenses, frames and two temples. They are used to improve vision, protect eyes or for decorative purposes. The frame and temples of the glasses are connected by hinges, so that the temples and the frame can rotate, making it easy to fold and store the temples when the glasses are not in use, thereby facilitating the placement of the glasses.

[0003] However, conventional eyeglass legs and eyeglass frames are fixed at the hinges by screws when they are hinged. This connection requires the use of a screwdriver when the eyeglass legs need to be removed and installed. Without a screwdriver of specified specifications, installation and removal cannot be completed, and the speed of twisting the screws with a screwdriver is relatively slow, which makes it inconvenient to quickly complete the disassembly and assembly of the eyeglass legs. At the same time, the screws will become loose as the use time increases, which may easily cause the screws to fall off and be lost, causing a lot of trouble to the user. Utility Model Content

[0004] The purpose of the utility model is to provide a hinge structure for glasses in order to solve the above problems, which is convenient for quick installation and removal of the temples and is stable and reliable after connection, so as to facilitate use by the wearer.

Since the plug block is a prismatic structure, the connection block and the plug shaft cannot rotate after the plug shaft and the plug block are engaged, and when the plug shaft is fully inserted into the connection block, the block will be engaged with the ring groove under the action of the first spring, and the plug shaft cannot be separated from the connection block. At this time, the rotation of the glasses leg will drive the connection block to move, and the connection block drives the plug shaft to rotate on the connection seat. The quick installation of the glasses legs is now completed. When the glasses legs are damaged and need to be disassembled and replaced, the swing rod can be pressed. The swing rod will rotate around the rotating shaft and drive the clamping block to move away from the annular groove. The first spring contracts. When the clamping block and the annular groove are not engaged, the plug-in shaft can be removed from the connecting block. When the plug-in shaft is removed, the connecting block can be removed from the connecting seat. The quick disassembly of the glasses legs is now completed, so that the glasses legs can be quickly disassembled and assembled without the help of a screwdriver, which effectively improves the convenience of operation. At the same time, the plug-in shaft will not loosen and fall off after installation, thereby effectively improving the stability of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 As shown, a hinge structure for glasses comprises a connecting seat 1, the connecting seat 1 is rotatably connected with an insertion shaft 4, the insertion shaft 4 is engaged with a connecting block 2, the connecting block 2 is fixedly connected with an insertion block 8, one end of the insertion shaft 4 is engaged with the insertion block 8, the connecting block 2 is fixedly connected to the temple 3 of the glasses, the connecting seat 1 is provided with a locking structure 5, the locking structure 5 comprises a rotating shaft 501, the connecting seat 1 is rotatably connected with the rotating shaft 501, a swing rod 502 is fixedly connected to the rotating shaft 501, a first spring 503 is in contact between the swing rod 502 and the connecting seat 1, a locking block 504 is fixedly connected to the swing rod 502, the insertion shaft 4 is provided with an annular groove 505, and the end of the locking block 504 is engaged with the annular groove 505.

[0022] As a technical optimization solution of the utility model, a slot 9 is provided at one end of the plug shaft 4, and the plug block 8 is engaged with the slot 9. One end of the cross-section of the plug block 8 is a trapezoidal structure, and the plug block 8 is a prismatic structure. Therefore, when the plug shaft 4 and the plug block 8 are engaged, rotation between the connecting block 2 and the plug shaft 4 can be avoided.

[0023] As a technical optimization solution of the utility model, one end of the cross section of the plug shaft 4 is a trapezoidal structure, and the other end of the cross section of the plug shaft 4 is a T-shaped structure, so it can play a guiding role when the plug shaft 4 is inserted into the connecting block 2.

[0024] As a technical optimization solution of the utility model, a stopper 6 is fixedly connected to the connecting block 2, and the stopper 6 is in contact with the connecting seat 1, so that the glasses legs 3 can be prevented from continuing to rotate after being opened, thereby facilitating the wearing of glasses.

[0025] As a technical optimization scheme of the utility model, a pressing structure 7 is provided on the connecting seat 1, and the pressing structure 7 includes a pressing block 701. The connecting seat 1 is slidably connected with the pressing block 701, and the plug shaft 4 is provided with two grooves 703. One end of the pressing block 701 extends to the inside of the groove 703 and contacts the plug shaft 4. A second spring 702 is provided inside the connecting seat 1, and one end of the second spring 702 contacts the pressing block 701, and the other end of the second spring 702 contacts the connecting seat 1. One end of the cross-section of the pressing block 701 is an arc-shaped structure, and the two grooves 703 are distributed at ninety degrees with respect to the axis of the plug shaft 4. Therefore, when the glasses leg 3 is stored or opened, a certain resistance is applied to it. When the external force is less than the resistance, the glasses leg 3 will not be able to rotate, thereby effectively improving the stability of use.

[0026] When the utility model is in use, the connection seat 1 and the eyeglass frame can be fixedly connected first, and then one end of the connection seat 1 can be placed inside the connection block 2, and the plug shaft 4 can be inserted into the connection block 2 from one end of the connection block 2 until the slot 9 at one end of the plug shaft 4 is engaged with the plug block 8. Since the plug block 8 is a prismatic structure, the connection block 2 and the plug shaft 4 cannot rotate after the plug shaft 4 is engaged with the plug block 8, and when the plug shaft 4 is fully inserted into the connection block 2, the block 504 will be engaged with the annular groove 505 under the action of the first spring 503, and the plug shaft 4 cannot be detached from the connection block 2. At this time, the rotation of the glasses leg 3 will drive the connection block 2 to move, and the connection block 2 drives the plug shaft 4 to rotate on the connection seat 1, and the quick installation of the glasses leg 3 is completed. When the glasses leg 3 is folded and stored, one end of the stop block 701 is located in one of the grooves under the action of the elastic force of the second spring 702. The inside of 703 is tightly pressed against the plug shaft 4, so a certain resistance can be applied to the eyeglass leg 3 after it is folded, so that when the external force is less than the resistance, the eyeglass leg 3 cannot be opened, thereby effectively improving the stability of use. When the eyeglass leg 3 is damaged and needs to be disassembled and replaced, the rocker bar 502 can be pressed, and the rocker bar 502 will rotate around the rotating shaft 501 and drive the clamping block 504 to move away from the annular groove 505, and the first spring 503 will contract. When the clamping block 504 and the annular groove 505 are not engaged, the plug shaft 4 can be removed from the connecting block 2. When the plug shaft 4 is removed, the connecting block 2 can be removed from the connecting seat 1. At this time, the quick disassembly of the eyeglass leg 3 is completed, so that the quick disassembly and assembly of the eyeglass leg 3 can be achieved without the help of a screwdriver, which effectively improves the convenience of operation. At the same time, the plug shaft 4 will not loosen and fall off after installation, thereby effectively improving the stability of use.
