Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to eyeglasses with replaceable nose pads. Background Technology

[0002] Eyeglasses consist of a frame, which primarily supports the lenses. A nose pad is located in the middle of the frame, which rests on the bridge of the wearer's nose to hold the glasses up when in use.

[0003] Existing eyeglasses, such as those disclosed in Chinese patent literature, include a replaceable nose pad frame [Patent No.: 202020680088.7; Application Publication No.: CN211786427U]. This frame includes a frame body, lens mounting holes on the left and right sides of the frame body, and a central beam in the middle of the frame body. A nose pad is located on the rear side of the central beam, and the nose pad includes a snap-fit ​​portion opposite to the central beam. Nose wings extend downwards from both ends of the snap-fit ​​portion, and the nose wings are integrally formed with the snap-fit ​​portion. A post is located at the center of the rear sidewall of the central beam. A central pin hole is located on the post. A matching insertion hole is located on the snap-fit ​​portion, and the post is inserted into the insertion hole. An upper pin hole is located on the upper surface of the snap-fit ​​portion, and a lower pin hole is located on the lower surface of the snap-fit ​​portion, coaxial with the upper pin hole.

[0004] In this type of frame, a pin passes downwards through the upper pin hole, the middle pin hole, and finally into the lower pin hole. The pins are interference-fitted with each other, securing the nose pads to the frame body. However, the pins in this design are relatively small, making them difficult to grasp. This results in inconvenient insertion of the pins into the upper, middle, and lower pin holes, making nose pad installation troublesome. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a glasses with replaceable nose pads, thus solving the technical problem of how to make the nose pads easy to install.

[0006] The objective of this utility model can be achieved through the following technical solution: a pair of glasses with replaceable nose pads, the glasses including a frame and nose pads, the frame having a central beam in the middle, and the nose pads having a connecting beam in the middle, characterized in that the central beam has an insertion hole in the middle of its rear side, the insertion hole having a snap-fit ​​hole for fixing in the hole wall, the connecting beam having a flexible snap-fit ​​connector, the connecting beam being embedded in the insertion hole and the snap-fit ​​connector being partially embedded in the snap-fit ​​hole, so that the frame and the nose pads are fixedly connected.

[0007] In use, the connecting beam is inserted into the insertion hole, and the snap-fit ​​connector, with its elastic part, is inserted into the snap-fit ​​hole. The snap-fit ​​connector engages with the center beam, thus securing the nose pads to the center beam and consequently, the frame and nose pads. This nose pad is secured to the frame via a snap-fit ​​method, eliminating the need for rotating screws or aligning multiple holes, making installation convenient.

[0008] In the aforementioned replaceable nose pad glasses, a buffer hole is provided in the middle of the rear side of the connecting beam. The buffer hole penetrates the bottom of the connecting beam. The snap-fit ​​connector is disposed in the buffer hole, and there is a certain distance between the snap-fit ​​connector and the wall of the buffer hole. The bottom of the snap-fit ​​connector is located below the bottom wall of the connecting beam. The snap-fit ​​hole is located in the bottom wall of the insertion hole, and the snap-fit ​​hole penetrates the bottom of the middle beam. The buffer hole provides a space for the snap-fit ​​connector to elastically deform, allowing the snap-fit ​​connector to deviate from a certain position when squeezed, enabling the snap-fit ​​connector to enter and exit the snap-fit ​​hole, thus facilitating the installation and removal of the nose pad. The snap-fit ​​hole is located at the bottom, while the snap-fit ​​hole is located at the top, which prevents impurities from entering the insertion hole.

[0009] In the aforementioned replaceable nose pad glasses, the snap-fit ​​connector includes a strip-shaped clamping part and a snap-fit ​​part located at the bottom of the clamping part. The bottom surface of the snap-fit ​​part is a guide surface that is inclined downwards along the front-back direction of the frame. The clamping part presses against the bottom wall of the insertion hole, and the snap-fit ​​part is embedded in the snap-fit ​​hole. When the connecting beam is inserted into the insertion hole, the guide surface acts as a guide and causes the snap-fit ​​connector to gradually deform, allowing the snap-fit ​​part to pass over the bottom wall of the insertion hole and embed itself into the snap-fit ​​hole. When the clamping part returns to its original shape, it elastically presses against the bottom wall of the insertion hole, so that the nose pad and the frame are fixedly connected and the nose pad will not wobble.

[0010] In the aforementioned replaceable nose pad glasses, the snap-fit ​​hole is a square hole, and the rear sidewall of the snap-fit ​​part is arranged vertically, allowing it to abut against the wall of the snap-fit ​​hole. This structure prevents the nose pad from falling off and improves its stability.

[0011] In the aforementioned replaceable nose pad glasses, a guide hole is provided on the top wall of the insertion hole, the guide hole penetrating the rear side wall of the middle beam. The top of the connecting beam has an upwardly protruding guide portion, which is embedded in the guide hole. The guide hole and guide portion serve a guiding function, ensuring that the connecting beam is inserted into the insertion hole in a predetermined direction, thus facilitating nose pad installation.

[0012] In the aforementioned replaceable nose pad glasses, the guide portion is located directly above the clip connector. The presence of a buffer hole reduces the strength of the connecting beam, while the guide portion increases the strength of the connecting beam, ensuring sufficient strength.

[0013] In the aforementioned replaceable nose pad glasses, the insertion hole is elongated, and both ends of the hole wall have inwardly protruding first stepped surfaces. The connecting beam is also elongated, and both ends of the connecting beam have inwardly recessed second stepped surfaces on their side walls. The second stepped surfaces abut against the first stepped surfaces. This allows the connecting beam to be better embedded in the insertion hole, resulting in a better fit between the connecting beam and the center beam, thus improving the stability of the nose pad.

[0014] In the aforementioned replaceable nose pad glasses, the frame further includes two lens rings, with both ends of the central beam fixedly connected to the two lens rings respectively. The two ends of the insertion hole extend to the connection points between the central beam and the two lens rings. This structure ensures the insertion hole is sufficiently long, increasing the contact area between the connecting beam and the central beam, and improving the stability of the nose pads after installation.

[0015] Compared with the prior art, the nose pad replacement glasses provided by this utility model only requires applying a certain external force to push the connecting beam into the insertion hole to fix the nose pad and the frame together, making the nose pad installation convenient; at the same time, the snap-fit ​​hole can be used to push the snap-fit ​​connector upward, and a certain external force can be applied to pull the connecting beam out of the insertion hole, making the nose pad removal convenient.
