Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a clamping hinge glasses. 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 glasses. During daily use, 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, it is necessary to often take off and put on the glasses. However, frequent opening and closing of the temple makes the temple vulnerable to external forces and expand outwards without resilience and deform, making the glasses less and less suitable for wearing, bringing inconvenience to users. At this time, it is necessary to repair or replace the temple. Generally, the temple and the frame are connected by bolt columns, 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 snap hinge glasses, which includes frame extension plates symmetrically arranged on 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. 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 and rotates to close. The shaft rod is composed of an upper shaft rod embedded and adapted to the lower shaft rod cavity. Through slots A and through slots B are provided on the top surface of the upper shaft rod and the bottom surface of the lower shaft rod cavity 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 to snap and engage with through slot A, and the lower front guide strip is adapted to snap and engage with through slot B. A number of equally spaced reverse buckling teeth are respectively arranged 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 buckling 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. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clamping hinge glasses to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present utility model provides the following technical solution: A clamping hinge glasses, comprising a spectacle frame, temple arms and a shaft rod. At the upper parts of both ends of the spectacle frame, extension plates are symmetrically and integrally arranged. A square notch for installing the shaft rod is arranged inside the extension plate. A clamping ring fixedly connected to one end of the temple arm is sleeved on the middle part of the outer wall of the shaft rod through a groove. Two mounting grooves are symmetrically arranged at the upper and lower ends of the extension plate. The inner walls of the opposite sides of the two mounting grooves located on one side of the spectacle frame are communicated with the inner wall of the square notch. A clamping block is arranged inside the mounting groove. One end of the clamping block far away from the spectacle frame is rotatably connected between the inner walls of both sides of the mounting groove. One end of the clamping block close to the spectacle frame abuts against the inner wall of the mounting groove. The two clamping blocks are used for clamping and fixing the upper and lower ends of the shaft rod.

[0006] Further, anti-reverse teeth are uniformly arranged on the outer wall of the clamping block on the side close to the square notch.

[0007] Further, a clamping groove is arranged in the middle of the outer wall of the clamping block close to the spectacle frame. A receiving groove is arranged on the inner wall of the mounting groove close to the spectacle frame. A connecting piece is installed in the receiving groove through a screw. An elastic limiting piece is integrally arranged on one side of the connecting piece close to the square notch. The cross section of the limiting piece is V-shaped, and the bending part is clamped in the clamping groove.

[0008] Further, two pressing grooves are symmetrically arranged on the opposite sides of the two clamping blocks. The pressing grooves are arranged far away from the spectacle frame. One end of the clamping block located at the end of the pressing groove is rotatably connected between the inner walls of both sides of the mounting groove.

[0009] Further, a resilient sheet is installed on the outer wall of the extension plate between the two clamping blocks through a screw. The two ends of the resilient sheet respectively extend obliquely towards the two pressing grooves and respectively abut against the inner walls on the opposite sides of the two pressing grooves.

[0010] Further, the shaft rod is composed of an upper shaft rod embedded and adapted to a lower shaft rod cavity.

[0011] The beneficial effects achieved by the present utility model are as follows:

[0012] 1. By simply pressing the clamping block, the loading and unloading of the shaft rod can be realized. This design enables users to easily replace or repair the glasses components, improves the convenience of use, and at the same time avoids the problem of the extension plate at the included angle of the square notch being damaged by force.

[0013] 2. Through the clamping design of the clamping groove and the limiting piece, the stability of the clamping block when clamping the shaft rod is ensured, thereby effectively preventing the clamping block from loosening during normal use, and thus improving the overall stability and safety of the glasses.

[0014] 3. By setting a pressing groove on the clamping block, the contact area between the clamping block and the inner wall of the mounting groove on the same side is reduced when the clamping block rotates, thereby effectively reducing the resistance during rotation.

[0015] 4. By installing the springback sheet, the elasticity of the springback sheet is used to generate continuous pressure on the pressing groove, and the lever principle is used to significantly enhance the clamping force of the clamp on the shaft, thereby further improving the stability and reliability of the clamping.

[0016] 5. After the clamping state is released, the springback sheet can automatically rebound and drive the clamp block to re-clamp the shaft rod. This automatic reset function greatly simplifies the re-clamping operation steps and improves the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-2 As shown, the utility model discloses a clamping hinge glasses, comprising: a frame 1, temples 2 and a shaft rod 3, the upper parts of both ends of the frame 1 are symmetrically and integrally provided with extension plates 4, a square notch 41 for installing the shaft rod 3 is provided in the extension plate 4, a clamping ring 21 fixedly connected to one end of the temple 2 is sleeved on the middle part of the outer wall of the shaft rod 3 by setting a groove 31, two mounting grooves 42 are symmetrically provided at the upper and lower ends of the extension plate 4, the inner walls of the opposite sides of the two mounting grooves 42 located on one side of the frame 1 are communicated with the inner wall of the square notch 41, a clamping block 43 is provided in the mounting groove 42, the end of the clamping block 43 away from the frame 1 is rotatably connected to the inner walls on both sides of the mounting groove 42, the end of the clamping block 43 close to the frame 1 abuts against the inner wall of the mounting groove 42, and the two clamping blocks 43 are used to clamp and fix the upper and lower ends of the shaft rod 3.

[0022] Further, such as Figure 2 As shown, undercut teeth 431 are evenly arranged on the outer wall of the clamping block 43 near the square notch 41 .

[0023] Based on the above structure, Figure 1-2As shown in the figure, during loading and unloading, first, press the ends of the two clamping blocks 43 away from the spectacle frame 1 with one hand, so that the ends of the clamping blocks 43 close to the spectacle frame 1 are disengaged from the inner wall of the installation groove 42, and the two clamping blocks 43 rotate to release the clamping of the upper and lower ends of the shaft rod 3. Then, move the shaft rod 3 in the direction away from the extension plate 4 on the same side and take it out for replacement. When reinstalling, press the end of the clamping block 43 close to the spectacle frame 1 against the installation groove 42 again. By simply pressing the clamping block, the loading and unloading of the shaft rod can be achieved. This design enables users to easily replace or repair spectacle parts, improving the convenience of use and avoiding the problem of damage to the extension plate at the included angle of the square notch due to force.

[0024] Furthermore, as Figure 2-3 shown, in order to prevent the clamping block from loosening during clamping, a clamping groove 432 is provided in the middle of the outer wall of the clamping block 43 close to the spectacle frame 1, and a receiving groove 421 is provided on the inner wall of the installation groove 42 close to the spectacle frame 1. A connecting piece 5 is installed in the receiving groove 421 by a screw. An elastic limiting piece 51 is integrally provided on one side of the connecting piece 5 close to the square notch 41. The cross-section of the limiting piece 51 is V-shaped, and the bent part is clamped in the clamping groove 432.

[0025] Specifically, when releasing the clamping of the shaft rod 3 by the two clamping blocks 43, insert an external tool (such as a metal sheet) into the receiving groove 421 until the end of the external tool abuts against the limiting piece 51. Then continue to insert the external tool. The external tool exerts pressure on the limiting piece 51, causing the limiting piece 51 to deform until the clamping between the limiting piece 51 and the clamping groove 432 is released. Then rotate the clamping block 43 to release the clamping of the two clamping blocks 43 on the shaft rod 3.

[0026] Furthermore, as Figure 3 shown, in order to reduce the resistance between the clamping block and the inner wall of the installation groove on the same side during rotation, two pressing grooves 433 are symmetrically provided on the opposite sides of the two clamping blocks 43. The pressing grooves 433 are arranged away from the spectacle frame 1. The clamping block 43 at the end of the pressing groove 433 is rotatably connected to the two inner walls of the installation groove 42. By providing the pressing grooves 433 on the clamping block 43, the contact area between the clamping block 43 and the inner wall of the installation groove 433 on the same side during rotation is reduced, thereby effectively reducing the resistance during rotation.

[0027] Furthermore, as Figure 3As shown in the figure, in order to further prevent the clamping block from loosening during clamping, a resilient piece 6 is installed on the outer wall of the extension plate 4 between the two clamping blocks 43 by screws. The two ends of the resilient piece 6 extend obliquely towards the two pressing grooves 433 respectively, and are respectively in contact with the inner walls on the opposite sides of the two pressing grooves 433. The setting of the resilient piece 6 can generate a pressure away from the mounting groove 42 on the pressing groove 433 through the elasticity of the resilient piece 6 itself, and the pressure acts on the side of the clamping block 43 close to the spectacle frame 1 through the lever principle, so that the clamping block 43 maintains the clamping state;

[0028] Furthermore, when it is necessary to release the clamping state of the two clamping blocks 43, press the end of the clamping block 43 away from the spectacle frame 1. The clamping block 43 rotates, and the extended end of the resilient piece 6 is bent under force. After the pressing on the clamping block 43 is released, the resilient piece 6 rebounds and drives the clamping block 43 to clamp the shaft rod 3 again.

[0029] Furthermore, as Figure 2-3 shown in the figure, the shaft rod 3 is composed of an upper shaft rod 32 embedded and adapted to a lower shaft rod cavity 33.

[0030] The above is only the preferred specific embodiment 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 and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
