Description

Technical Field

[0001] The utility model belongs to the technical field of glasses and relates to a glasses temple connection structure. Background Art

[0002] Glasses consist of lenses and frames. Traditionally, the frame and temples of glasses are connected by hinges. These hinged temples are difficult to disassemble and replace. Furthermore, a rotating shaft typically passes between the hinge and the frame, with retaining rings at each end. This makes assembly of the hinge and frame difficult. In response to this situation, a pair of glasses with convenient replacement of glasses legs has appeared on the market, such as the glasses with convenient replacement of glasses legs described in Chinese Patent No.: "202221241798.5". The specific structure of the glasses is as follows: it includes a frame, temples and a connecting piece, the lenses are fixedly installed inside the frame, fixed blocks are fixed at both corners of one side of the frame, a connecting piece is rotatably connected between the two fixing blocks, a connecting mechanism is provided between the connecting piece and the fixing block, a connecting block is fixedly provided on the side of the connecting piece, a connecting groove is provided at the end of the temple, the connecting block is embedded in the connecting groove, clamping holes are provided on both sides of the connecting groove, a groove is provided on the top of the connecting block, wedge-shaped clamping blocks are inserted and connected on both sides of the groove, the two wedge-shaped clamping blocks are clamped and connected with the corresponding clamping holes, a fixing plate is fixedly installed on one side of the two wedge-shaped clamping blocks, and an extrusion spring is fixedly installed between the two fixing plates. When the temples need to be replaced, first manually squeeze the wedge-shaped block in the middle to separate the wedge-shaped block from the hole, then manually pull the temples outward to separate the connecting block from the connecting groove to complete the disassembly of the temples, then re-insert the connecting groove and the connecting block at the end of the new temples, and use the extrusion spring to squeeze the wedge-shaped block and the hole to complete the replacement of the temples.

[0003] When the glasses are worn out, the user has to manually adjust the position of the temples so that they can be put back into the glasses, and the movement of the temples will cause the temples to rotate automatically due to gravity or other reasons. This will affect the user's wear. For example, when the user needs to wear the glasses with one hand, after the two temples are spread apart, the temples will often automatically rotate to the closed position during the movement, making it impossible to wear the glasses. At the same time, the installation and disassembly of the temples mainly rely on the elasticity of the extrusion springs, but the springs are consumable parts and are easily damaged and scrapped, resulting in unstable installation of the temples. At the same time, when the temples are disassembled, it is necessary to manually squeeze the wedge-shaped blocks on both sides toward the middle at the same time so that the wedge-shaped blocks on both sides are separated from the card holes at the same time. Since the wedge-shaped blocks are small in structure, it is difficult to apply force when squeezing, and tools are often required to press the wedge-shaped blocks on both sides inward at the same time. The above disassembly process is cumbersome and very laborious. Summary of the Invention

[0004] The object of the present utility model is to provide a spectacle temple connection structure that prevents the temple body from automatically rotating due to gravity in view of the above problems existing in the prior art.

[0005] The object of the present utility model can be achieved by the following technical solutions: A spectacle temple connection structure includes a spectacle frame and temple bodies located on both sides of the spectacle frame. Hollow mounting blocks are provided at both ends of the spectacle frame. A connecting block is provided inside the mounting block. A connecting groove is formed in the middle of the connecting block. The end of the temple body is bent to form a hook. The hook hooks the connecting groove to rotatably connect the temple body and the spectacle frame. At the same time, the inner peripheral surface of the hook closely adheres to the connecting groove so that there is a frictional force between the hook and the connecting groove that hinders the automatic rotation of the temple body. The temple body can rotate relative to the connecting block and the spectacle frame due to an external force.

[0006] In the above-mentioned spectacle temple connection structure, a bent section is formed at the connection between the tail of the hook and the temple body. The opening direction of the bent section is opposite to the opening direction of the hook. When the temple body is in the open state, the side wall of the mounting block contacts the bent section.

[0007] In the above-mentioned spectacle temple connection structure, the bent section is V-shaped.

[0008] In the above-mentioned spectacle temple connection structure, mounting grooves are formed at both ends of the connecting block. The two side groove walls of the mounting block are respectively snapped into the two mounting grooves, so that the connecting block is slidably mounted inside the mounting block.

[0009] In the above-mentioned spectacle temple connection structure, a card slot is also formed on the connecting block. A positioning block is integrally formed in the middle of the mounting block. Slide the connecting block so that the positioning block snaps into the card slot. At this time, the connecting block is installed in place.

[0010] In the above-mentioned spectacle temple connection structure, two limiting protrusions are provided on the side surface of the positioning block. When the temple body rotates, the tail of the hook is located between the two limiting protrusions.

[0011] In the above-mentioned spectacle temple connection structure, a protruding portion is provided in the middle of the connecting block. The side surface of the protruding portion is obliquely connected to the connecting block. The connecting groove is located in the middle of the protruding portion.

[0012] Compared with the prior art, the spectacle temple connection structure of the present invention realizes the rotational connection between the temple body and the spectacle frame through the cooperation of the hook and the connection block. Moreover, the friction force between the hook and the connection groove enables the temple body not only to maintain the open or closed state, but also to maintain any state where the rotation stops, preventing the temple body from automatically rotating due to gravity and facilitating use. The bent section is provided to avoid the contact between the temple body and the mounting block during the opening process, preventing interference between the two, and also plays a role in limiting the rotation of the temple body, preventing the temple body from rotating excessively and facilitating the positioning of the temple body in the open state.

[0016] The following are specific embodiments of the present invention in combination with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0017] Such as Figure 1 and Figure 2As shown, the present eyeglass temple connection structure comprises a frame 1 and temple bodies 2 located on either side of the frame 1. Both ends of the frame 1 are provided with hollow mounting blocks 11, within which connecting blocks 3 are mounted. A connecting groove 31 is formed in the middle of the connecting block 3. The ends of the temple bodies 2 are bent to form hooks 21, which engage the connecting groove 31 to provide a rotational connection between the temple body 2 and the frame 1. The inner circumference of the hook 21 abuts the connecting groove 31, creating friction between the hook 21 and the connecting groove 31 that hinders the automatic rotation of the temple body 2. This friction causes the connecting block 3 to damp the temple body 2 during rotation, thereby preventing the temple body 2 from automatically rotating due to gravity. The temple body 2 can only rotate relative to the connecting block 3 and the frame 1 due to external force. This external force is primarily manual manipulation of the temple body 2, and when the hand no longer applies force, the temple body 2 stops rotating and remains in its current state. The cooperation between the hook 21 and the connecting block 3 not only realizes the rotational connection between the temple body 2 and the frame 1, but also the friction between the hook 21 and the connecting groove 31 enables the temple body 2 to be maintained not only in an open or closed state, but also in any rotation stop state, which is convenient for use.

[0018] In the above technical solution, the tail of the hook 21 is bent at the junction with the temple body 2 to form a V-shaped bent section 22, with the opening direction of the bent section 22 being opposite to that of the hook 21. When the temple body 2 is in the open position, the sidewall of the mounting block 11 contacts the bent section 22, preventing the temple body 2 from rotating further outward. The bent section 22 not only avoids contact between the temple body 2 and the mounting block 11 during the opening process, preventing interference between the two, but also serves as a rotation limiter for the temple body 2, preventing excessive rotation and facilitating the positioning of the temple body 2 in the open position.

[0019] In the above technical solution, mounting grooves 32 are formed at both ends of the connecting block 3. The groove walls on both sides of the mounting block 11 are respectively snapped into the two mounting grooves 32, so that the connecting block 3 can be slidably installed in the mounting block 11. A snap-in groove 33 is also formed on the connecting block 3. A positioning block 12 is integrally formed in the middle of the mounting block 11. The sliding connecting block 3 causes the positioning block 12 to snap into the snap-in groove 33. At this point, the connecting block 3 is installed in place, and then the hook 21 hooks into the connecting groove 31. The hook 21 causes the connecting groove 31 to contract and fit tightly against the positioning block 12, ensuring a stable fit between the connecting block 3 and the positioning block 12, and preventing the temple body 2 from moving back and forth during use, which would affect the use.

[0020] In the above technical solution: two limiting protrusions 13 are provided on the side of the positioning block 12. When the temple body 2 rotates, the tail of the hook 21 is located between the two limiting protrusions 13. The limiting protrusions 13 prevent the hook 21 from moving left and right relative to the connecting block 3 when rotating.

[0021] In the above technical solution: a protruding portion 34 is provided in the middle of the connecting block 3. The side surface of the protruding portion 34 is obliquely connected to the connecting block 3. The connecting groove 31 is located in the middle of the protruding portion 34. By providing the protruding portion 34 and arranging the connecting groove 31 on the protruding portion 34, the connecting groove 31 can have a certain thickness, increasing the strength and ensuring the service life of the connecting block 3.

[0022] The spectacle temple connecting structure realizes the rotational connection between the temple body 2 and the spectacle frame 1 through the cooperation of the hook 21 and the connecting block 3. The frictional force between the hook 21 and the connecting groove 31 enables the temple body 2 not only to maintain the open or closed state, but also to maintain any state of rotational stop, preventing the temple body 2 from automatically rotating due to gravity and facilitating use. The bent section 22 not only avoids the contact between the temple body 2 and the mounting block 11 during the opening process to prevent interference between the two, but also plays a role in limiting the rotation of the temple body 2 to prevent the temple body 2 from rotating excessively and facilitating the positioning of the temple body 2 in the open state.
