Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a pair of glasses with a quickly detachable buckle hinge. Background Art

[0002] For traditional glasses, the temple and the frame generally adopt a bending method of embedding into a round hole and are fixed with a screw hinge. The screws used are non-standard parts, and professional maintenance personnel need to use special tools to assemble the temple and the frame, which brings inconvenience to the installation and maintenance of the glasses. During daily use, the glasses inevitably come into contact with external substances such as dust, water stains, and oil stains and react with them to cause corrosion. As a result, the temple gets stuck or loosens and falls off during the opening and closing process. When using glasses, they need to be taken off and put on frequently. However, frequent opening and closing of the temple makes the temple vulnerable to external forces and expand without rebound, resulting in deformation and making the glasses less and less suitable for wearing, bringing inconvenience to users. At this time, the temple needs to be repaired or replaced. Generally, the temple and the frame are connected by a bolt column, and professional maintenance personnel need to use special tools to install the temple and the frame, and the installation is cumbersome and inconvenient. To solve the problems existing in the prior art, people have carried out long-term exploration and proposed various solutions.

[0003] For example, as the Chinese patent authorization publication number: CN218728412U, the authorization publication date: March 24, 2023, discloses a new type of buckle hinge glasses, including frame extension plates symmetrically arranged at the upper parts of both ends of the frame. The frame extension plates are integrally formed with the frame. A square notch is provided in the inner frame of the frame extension plate, and a shaft rod is fixedly arranged in the square notch. A snap ring at one end of the temple is sleeved in the groove on the outer surface of the shaft rod for rotary closing. The shaft rod is composed of an upper shaft rod embedded and adapted to the cavity of the lower shaft rod. Through slots A and through slots B are provided on the top surface of the upper shaft rod and the bottom surface of the cavity of the lower shaft rod respectively. The through slots A and through slots B on both end surfaces of the shaft rod are respectively adapted to the front guide strips on the front side edges in the square notch. The front guide strips include an upper front guide strip and a lower front guide strip in the square notch. The upper front guide strip is provided to be adapted and engaged with through slot A, and the lower front guide strip is adapted and engaged with through slot B. A number of equally spaced reverse buckle teeth are respectively provided on the end surfaces of the upper front guide strip and the lower front guide strip. The rear side edge in the square notch in the inner frame of the frame extension plate is a rear step surface, and its rear step surface is respectively adapted to both end surfaces of the shaft rod. The side surface of the shaft rod is flush with the rear side surface of the square notch. The disadvantage is that when removing the shaft rod, it is necessary to expand the height of the inner wall of the square notch to release the fixation of the reverse buckle teeth on the upper and lower ends of the shaft rod. During the process of expanding the height of the inner wall of the square notch, it is necessary to apply reverse pressure to the upper and lower inner walls of the square notch, which easily causes the extension plate at the included angle of the square notch to be damaged by force. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pair of fast-detachable buckle hinge glasses to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a pair of quickly detachable buckle hinge glasses, comprising a frame, a shaft and temples, wherein the upper parts of the two ends of the frame are symmetrically and integrally provided with extension plates, the inner frame of the extension plate is provided with a square notch, the middle part of the outer wall of the shaft is provided with a clamping ring fixedly connected to one end of the temple through a groove, a U-shaped frame for installing the shaft is fixedly connected in the square notch, and also comprises two fixing members symmetrically arranged at the two ends of the frame, the fixing members comprising a pressing piece and two symmetrically and integrally arranged on the pressing piece near one end of the frame, The U-shaped frame has an insert block on the side, and one end of the insert block close to the frame is integrally provided with a flexible insert strip, and one side of the two insert strips opposite to each other is integrally and evenly spaced with a plurality of undercut teeth for fixing the two ends of the shaft rod, and two sockets are symmetrically arranged in the extension plate, and the sockets are used for inserting the insert block and the insert strip on the same side, and the inner walls of the two sockets are respectively connected with the upper and lower inner walls of the square notch close to one end of the pressing piece, and a plurality of through grooves for the undercut teeth to pass through are arranged on the upper and lower inner walls of the U-shaped frame, and a spring sheet is arranged between the pressing piece between the two insert blocks and the end of the frame.

[0006] Furthermore, the side of the undercut tooth close to the U-shaped frame is inclined toward the socket in the direction from the pressing plate to the frame.

[0007] Furthermore, two limiting grooves are symmetrically arranged on the outer walls on both sides of the end of the extension plate, and a clip integrally arranged with the pressing plate is fitted and slidably connected in the limiting groove.

[0008] Furthermore, two slots are symmetrically arranged at the upper and lower ends of the shaft rod, and the inner walls of the slots are adapted to the outer walls of the U-shaped frame and are arranged to slide relative to each other.

[0009] Furthermore, the shaft rod is composed of an upper shaft rod embedded in and adapted to a lower shaft rod cavity, and the two slots are respectively arranged at the top end of the upper shaft rod and the bottom end of the lower shaft rod cavity.

[0010] The beneficial effect achieved by the utility model is that, by means of the fixing piece cooperating with the slotted arrangement in the extension plate, when the temples are installed and removed, it is only necessary to press the pressing piece to drive the two inserts to bend to the opposite sides, so that the undercut teeth can release the clamping of the two ends of the shaft rod, thereby achieving easy replacement of the temples, greatly improving the convenience of use, and solving the problem of the extension plate being damaged by force.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] As Figures 1-3 shown, the present invention discloses a quickly detachable snap hinge glasses, including: a frame 1, a shaft rod 4 and temple 3. On the upper parts of both ends of the frame 1, extension plates 2 are symmetrically and integrally arranged. A square notch 21 is arranged inside the extension plate 2. A snap ring 31 fixedly connected to one end of the temple 3 is sleeved on the middle part of the outer wall of the shaft rod 4 through a groove 41. The glasses also include two fixing members 5 symmetrically arranged at both ends of the frame 1. The fixing member 5 includes a pressing piece 51 and two insertion blocks 52 symmetrically and integrally arranged on the side of the pressing piece 51 close to the frame 1. An insertion strip 53 with flexibility is integrally arranged at one end of the insertion block 52 close to the frame 1. A plurality of reverse buckles 531 for fixing both ends of the shaft rod 4 are integrally and equidistantly arranged on the opposite sides of the two insertion strips 53. Two insertion openings 23 are symmetrically arranged up and down inside the extension plate 2. The insertion openings 23 are used for inserting the insertion blocks 52 and the insertion strips 53 on the same side. The inner walls of the two insertion openings 23 are respectively communicated with the upper and lower inner walls of one end of the square notch 21 close to the pressing piece 51. A U-shaped frame 22 for installing the shaft rod 4 is fixedly connected inside the square notch 21. A plurality of through grooves 221 for the reverse buckles 531 to pass through are arranged on the upper and lower inner walls of the U-shaped frame 22. A spring piece 54 is arranged between the pressing piece 51 located between the two insertion blocks 52 and the end of the frame 1.

[0016] Based on the above structure, as Figures 1-3 shown, during loading and unloading, first press the two pressing pieces 51 towards the frame 1 with one hand. The spring piece 54 contracts. The pressing piece 51 drives the insertion strip 53 to move into the insertion opening 23 through the insertion block 52. During the movement of the insertion strip 53, the reverse buckles 531 are driven. The reverse buckles 531 move away from the U-shaped frame 22 under the resistance of the through groove 221, thereby driving the insertion strip 53 to bend. The mutually symmetric reverse buckles 531 release the clamping of both ends of the shaft rod 4. Then, move the shaft rod 4 in the direction away from the pressing piece 51 on the same side and take it out. Then release the pressing on the pressing piece 51. The spring piece 54 rebounds and drives the pressing piece 51, the insertion block 52, the insertion strip 53 and the reverse buckles 531 to reset. When reinstalling, press the pressing piece 51 again. After installing the shaft rod 4 into the U-shaped frame 22, release the pressing on the pressing piece 51;

[0017] Meanwhile, when the insert 53 is bent and broken for a long time, the fixing member 5 can be directly separated from the extension plate 2, and a new fixing member 5 can be replaced. Compared with replacing the lens frame 1, the maintenance cost is greatly reduced.

[0018] Furthermore, as Figure 2 shown, in order to increase the movement effect away from the U-shaped frame when the reverse buckle teeth are resisted by the through groove, one side of the reverse buckle teeth 531 close to the U-shaped frame 22 is inclined towards the socket 23 in the direction from the pressing piece 51 to the lens frame 1.

[0019] Furthermore, as Figures 2-3 shown, in order to avoid the loss of the spring piece and increase the stability of the pressing piece during movement, two limiting grooves 24 are symmetrically arranged on the outer walls of both sides of the end of the extension plate 2. A clip 511 integrally provided with the pressing piece 51 is fitted and slidably connected in the limiting grooves 24. The two clips 511 clamp the end of the extension plate 2, thereby increasing the stability of the pressing piece 51 during movement. At the same time, the two clips 511 and the pressing piece 51 form a cavity for accommodating the spring piece 54, so as to achieve the effect of preventing the spring piece 54 from being lost.

[0020] Furthermore, as Figure 2 shown, in order to increase the stability of the shaft rod installation, two slots 42 are symmetrically arranged at the upper and lower ends of the shaft rod 4. The inner wall of the slot 42 is adapted to the outer wall of the U-shaped frame 22 and is relatively slidably arranged. The upper and lower sides of the U-shaped frame 22 are respectively inserted into the two slots 42, so as to limit the shaft rod 4 in the front-rear direction.

[0021] Furthermore, as Figure 2 shown, in order to facilitate the replacement of the temple, the shaft rod 4 is composed of an upper shaft rod 43 embedded and adapted to a lower shaft rod cavity 44. The two slots 42 are respectively arranged at the top of the upper shaft rod 43 and the bottom of the lower shaft rod cavity 44. After the shaft rod 4 is taken out, the embedding between the upper shaft rod 43 and the lower shaft rod cavity 44 is released, and the temple 3 together with the snap ring 31 is taken out and replaced.

[0022] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
