Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a plug-in hinge glasses. Background Technique

[0002] For traditional glasses, the temple and the frame generally adopt a bending method of embedding in 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 may get stuck or loosen and fall 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 outward without resilience, resulting in deformation and 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 made long-term explorations and proposed various solutions.

[0003] For example, Chinese Patent Authorization Publication No.: CN218728412U, Authorization Publication Date: March 24, 2023, discloses a new type of snap hinge glasses, including frame extension plates symmetrically arranged on the upper parts at 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 fit and engage the through slot A, and the lower front guide strip is adapted to fit and engage the through slot B. A number of equally spaced reverse buckle 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 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 due to stress.

[0020] The present utility model will be further described below with reference to the drawings.

[0021] As Figures 1-3As shown, the utility model discloses a plug-in hinged glasses, comprising: a frame 1, two temples 2 and two shafts 3, two extension mechanisms 4 for plugging the symmetrical side shafts 3 are symmetrically arranged on the upper parts of both ends of the frame 1, the extension mechanism 4 comprises an extension block 41 integrally connected to the end of the frame 1 and a clamping block 42 with an L-shaped cross section, a slot 411 is arranged on the side wall of the extension block 41, two first limiting grooves 412 are symmetrically arranged on the inner walls on the upper and lower sides of the slot 411, a connecting rod 421 is slidably arranged in the slot 411, and the connecting rod 421 and the clamping block 42 are close to one end of the extension block 41 An integral arrangement is provided, with two limit blocks 422 symmetrically provided at the upper and lower ends of the connecting rod 421 away from the clamping block 42, the limit blocks 422 are fitted with and slidably connected to the inner wall of the first limit groove 412 on the corresponding side, a pressure spring 413 is provided in the first limit groove 412, the two ends of the pressure spring 413 are respectively abutted against the inner wall of the first limit groove 412 close to the clamping block 42 and the outer wall of the limit block 422 close to the clamping block 42, the inner wall of the clamping block 42 and the outer wall of the extension block 41 clamp the shaft rod 3, the cross-section of the shaft rod 3 is I-shaped, and the connecting end of the temple 2 is sleeved and rotatably connected to the middle part of the shaft rod 3.

[0022] Based on the above structure, Figures 1-3 As shown, during loading and unloading, the clamping block 42 is pulled to the side away from the frame 1, and the clamping block 42 drives the limit block 422 to slide along the first limit groove 412 to the side away from the frame 1 through the connecting rod 421, and the limit block 422 applies pressure to the compression spring 413, the compression spring 413 contracts, and the clamping block 42 releases the clamping of the shaft rod 3, and then the compression spring 413 rebounds and drives the clamping block 42, the connecting rod 421 and the limit block 422 to reset, and the temple 2 can be repaired or replaced. When reinstalling, the shaft rod 3 with the temple 2 is directly pressed between the clamping block 42 and the extension block 41, and the clamping block 42 is forced to move to the side away from the frame 1 until the top of the shaft rod 3 is in contact with the top of the inner wall of the clamping block 42, and the compression spring 413 drives the clamping block 42 to re-clamp the shaft rod 3 through the limit block 422 and the connecting rod 421 in turn.

[0023] Further, such as Figure 3As shown, in order to avoid the position deviation of the shaft rod when it is installed and to avoid displacement of the shaft rod after installation, two limit strips 43 are symmetrically arranged on the outer wall of the extension block 41 located below the top of the inner wall of the clamping block 42 and on the inner wall of the clamping block 42 on the side away from the frame 1. The two limit strips 43 are fixedly connected to the outer wall of the extension block 41 and the inner wall of the clamping block 42 respectively, and two second limit grooves 31 are symmetrically arranged on the outer wall of the shaft rod 3.

[0027] During loading and unloading, the thumb is pointed downward to press the end of the block 44, and then the thumb is used to push the end of the block 44 downward, so that the end of the block 44 is deformed and the connection with the slot 423 is released. Then, the block 44 is affected by gravity and rotates downward with the hinge as the center. Then the temple can be replaced. After the replacement is completed, the end of the block 44 is pushed upward and the end of the block 44 is re-connected with the slot 423.

[0028] Further, such as Figure 3 As shown, in order to increase the stability of the connection between the end of the block and the slot, a convex strip 441 is provided on the inner wall of the end of the block 44, and a strip groove 424 for the convex strip 441 to engage is provided on the inner wall of the slot 423, and the strip groove 424 limits the convex strip 441.

A snap ring 22 is integrally provided at the connecting end of the L-shaped extension rod 21. The snap ring 22 is sleeved and rotatably connected to the middle of the shaft rod 3. A receiving groove 414 for receiving the connecting end of the L-shaped extension rod 21 is provided on the outer wall of the extension block 41 close to the temple 2. When the temple 2 is folded, the two temples 2 rotate towards the opposite side until the connecting end of the L-shaped extension rod 21 completely enters the receiving groove 414, and the folding of the temple is completed. The settings of the L-shaped extension rod 21 and the receiving groove 414 provide a rotating space for the temple 2.

[0030] Further, as Figure 3 shown, for the convenience of detaching the temple, the shaft rod 3 is composed of an upper shaft rod 32 embedded and adapted in a lower shaft rod cavity 33. When the temple 2 is detached, the embedding between the upper shaft rod 32 and the lower shaft rod cavity 33 is released.
