Description

Technical Field

[0001] The utility model relates to the field of glasses, in particular to a quick-connect elastic structure and glasses. Background Art

[0002] Glasses are a simple optical device made for correcting vision or protecting the eyes. They are mainly composed of lenses and frames. The lenses have the functions of adjusting the light entering the eyes, correcting vision, protecting eye safety and clinically treating eye diseases, while the frames are matched with the lenses to form glasses that are worn on people's eyes and act as a support.

[0003] A glasses frame usually consists of a frame and temples. Temples are pivotally mounted on both sides of the frame. The frame and temples are connected by a post and a hinge. Conventional temples and hinges are fixed together and cannot be disassembled. The connection between the hinge and the post can only be released by screws or other means, and then the temples can be disassembled. When using this connection method, the entire hinge and temples need to be replaced together.

[0004] However, as consumers increasingly prioritize the aesthetics of their glasses, glasses with interchangeable temples are becoming increasingly popular. For example, Chinese Patent CN118688982A discloses a structure with interchangeable temple ornaments. This structure primarily achieves changes in temple appearance by designing interchangeable ornaments on the temples. However, this approach is limited by the type of ornament structure, and the overall shape and color of the temples cannot be changed.

[0005] Chinese patent CN221351885U discloses a detachable temple for glasses, in which the hinge structure is designed as a curved member, which cooperates with the pin on the pile head to realize the detachable connection of the temple. However, this method still requires the hinge and the temple to be replaced together, and the replacement cost is relatively high.

[0006] Chinese patent CN221707825U discloses a pair of glasses with a snap-on interchangeable temple structure. The hinge is designed to snap onto the temple, allowing for quick removal of the temple and hinge. While this method eliminates the need to replace both the temple and hinge, the snap-on design is complex and, due to the small size of the temple, can lead to an unreliable connection. This can lead to wear and aging of the snap-on structure over time, compromising the secure connection.

[0007] In order to achieve rapid replacement of the temples and reduce replacement costs, a low-cost connection between the temples and the hinges is required. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] like Figure 1 As shown, it is a temple with an elastic structure for quick connection, wherein the connector 100 is inserted into the plug-in hole of the temple, and the connector is limited to the temple by the limiting cooperation between the connector and the temple, that is, a plug-in hole 300 is set at one end of the temple 200, and a positioning member 400 / limiting member is provided in the plug-in hole 300. The connector 100 has one end set as a pivotal portion 140 pivotally connected to the frame / stump, and the other end can be inserted into the plug-in portion 130 in the plug-in hole 300, and the plug-in portion 130 is provided with a limiting member / positioning member that forms a limiting cooperation with the positioning member 400 / limiting member. The limiting member and the positioning member 400 form a limiting cooperation to limit the connector 100 from coming out.

[0029] The limiting fit can be an interference fit, using the interference fit of the connector and the socket to achieve fixation of the two, but this method may cause wear after long-term use, resulting in poor fit. Alternatively, a snap-fit fit of convex and concave points and grooves can be used, that is, convex points or grooves are set on the connector, and grooves or convex points are set in the socket, and the two are locked together to achieve fixation, but this method requires a slight force for plugging and unplugging.

[0030] The best Figure 2 and Figure 3As shown, another embodiment is disclosed, which discloses a quick-connect elastic structure, which adopts a rotary limiting method, that is, the axis is inserted and then the anti-escape limit is achieved by rotation. This method is easy to operate.

[0031] like Figure 4 As shown, one end of the plug-in portion 130 is provided with an L-shaped groove composed of a horizontal groove 120 and a vertical groove 110, and a positioning member 400 is provided in the plug-in hole 300. The positioning member 400 and the vertical groove 110 form a circumferential limit and axial sliding fit, and the positioning member 400 and the horizontal groove 120 form a circumferential rotation and axial limit fit.

[0032] At the same time, the L-shaped groove can also be designed on the inner wall of the plug hole. In this way, a positioning piece, such as a protrusion, is provided on the plug part.

[0033] In one embodiment, the positioning member 400 is a protrusion provided on the inner wall of the plug hole 300 and is directly integrally formed on the inner wall of the plug hole, and the protrusion and the L-shaped groove are fixed by sliding and rotating.

[0034] As another way, the positioning member 400 is a pin, and a positioning hole is provided on one side of the temple 200, and the pin passes through the positioning hole and partially enters the plug hole 300. This way is more convenient to process.

[0035] The L-shaped groove is arranged in parallel with the pivoting portion 140, and the leading edge is arranged in parallel, so that when the positioning piece arranged perpendicular to it cooperates with the L-shaped groove, the pivoting portion is just in a horizontal direction, so that when it is pivoted to the frame or the head, the temple can be opened or closed normally.

[0036] The pivoting portion 140 is a circular ring, which is convenient for pivoting with the mirror frame or the head.

[0037] In another embodiment, the circumferential portion of the end of the plug-in part protrudes outward, a corresponding annular groove is provided in the plug-in hole, and a guide groove is provided along the axial direction of the plug-in hole. The guide groove is connected to the annular groove at the bottom. After the protrusion of the plug-in part is inserted into the annular groove along the guide groove, anti-escape limiting can be achieved by rotation. The protrusion can be in various forms and is designed according to the actual product.

[0038] An elastic member is provided between the connector 100 and the temple 200. The elastic member is a spring, which is deformed by pressure when the connector is inserted. When the limit on the connector is released, the elastic member resets and pushes the connector outward for easy disassembly.

[0039] The present invention also provides a pair of glasses adopting the above-mentioned quick-connect elastic structure, which includes a frame and temples 200, and the above-mentioned quick-connect elastic structure is provided between the frame and the temples 200.

[0040] At the same time, an integral or separate stud head may be provided on the mirror frame, and the stud head is pivotally connected to the pivotal connection portion of the quick-connect elastic structure.

[0041] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the scope of protection of the present invention.
