Description

Technical Field

[0001] The utility model relates to the field of glasses, in particular to a pair of detachable and replaceable glasses. Background Art

[0002] At present, glasses consist of lenses and frames, and are mainly divided into two categories: vision correction glasses and goggles. Most glasses frames generally use temples to hang on the user's ears for daily use. Some glasses frames use headbands to tighten on the user's head for use in sports and other situations.

[0003] In the prior art, a pair of glasses with detachable temples comprises a lens frame and temples that are hinged to each other, the lens frame is provided with a hinged portion, the temple comprises an elastic connector whose one end is hinged to the hinged portion and a temple body sleeved outside the elastic connector, the elastic connector is provided with a limiting convex portion, the temple body is provided with an adapting groove, and the groove wall of the adapting groove is provided with a limiting notch. When the glasses are installed, the elastic connector is inserted into the adapting groove to elastically deform the elastic connector until the limiting convex portion and the limiting notch are in a position opposite to each other, the elastic connector is restored, and the limiting convex portion is driven to engage and connect with the limiting notch, so that the temple body and the elastic connector can be fixedly connected; in this way, when the glasses need to be disassembled or the temples need to be replaced, it is only necessary to press the limiting convex portion in the limiting notch to elastically deform the elastic connector, and then the temple body can be pulled out for replacement.

[0004] As can be seen from the above, the glasses can be freely disassembled and replaced with different styles of temples without the aid of tools. However, if the temples are replaced with headbands, when used, tightening the headband will cause the two ends of the lens frame to fit tightly against the skin of the head. The lens frame is usually made of rigid material, and when it fits against the skin, it will scratch the skin of the head and leave obvious indentations, which makes the wearing comfort poor. Therefore, the existing detachable glasses are not suitable for disassembling and assembling the temples and replacing them with headbands. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The utility model provides a pair of detachable and replaceable glasses, which are used to solve the problem of how to improve the comfort when wearing the glasses through a headband.

[0035] See also Figure 1 and Figure 2 As shown, Figure 1 Schematic diagram of the structure of the detachable and replaceable locking block of the glasses on the connecting frame in the embodiment, Figure 2 It is a schematic structural diagram of a locking block of a detachable and replaceable pair of glasses on a lens frame and a connecting frame in an embodiment. The detachable and replaceable pair of glasses comprises a frame 1, and the frame 1 comprises a lens frame 11, a connecting frame 12 and a locking block 3.

[0036] The connecting frame 12 is arranged on the temple 13 or the headband by integral connection or bonding. The lens frame 11 and the connecting frame 12 are rotatably connected.

[0037] The locking block 3 is configured to be slidably connected to the lens frame 11 or the connecting frame 12 .

[0038] When the frame 1 is unfolded and the locking block 3 slides between the lens frame 11 and the connecting frame 12 , the locking block 3 restricts the connecting frame 12 from rotating relative to the lens frame 11 , thereby locking the frame 1 in the unfolded position.

[0039] When the detachable and replaceable glasses provided by the above technical solution are used, the initial position of the locking block 3 can be located on the lens frame 11 or the connecting frame 12. At this time, the connecting frame 12 can rotate relative to the lens frame 11 so as to fold or unfold the frame 1. However, if the temples 13 of the frame 1 are replaced with a headband, before wearing the headband, the frame 1 needs to be unfolded first, and then the locking block 3 is slid between the lens frame 11 and the connecting frame 12 to lock the connecting frame 12 of the headband so that it cannot rotate relative to the lens frame 11. Finally, the headband is worn. In this way, the locking block 3 locks the connecting frame 12 of the headband in the unfolded position to open a certain space between the headband and the head skin, effectively preventing the tightening of the headband from driving the two ends of the lens frame 11 to press against the head skin, thereby effectively improving the comfort when wearing with the headband, so that the detachable and replaceable glasses are suitable for disassembling the temples and replacing them with the headband.

[0040] See also Figure 1 , Figure 2 and Figure 3 As shown, Figure 3The exploded view of the structure of the lens frame, the connecting frame, the adapter block and the locking block in the embodiment, in one embodiment in which the lens frame 11 and the connecting frame 12 are rotatably connected, the lens frame 11 or the connecting frame 12 has a connecting hole 21. The connecting frame 12 or the lens frame 11 includes an elastic support foot 221 and a connecting protrusion 222. The connecting protrusion 222 is connected to the elastic support foot 221 by integral connection or bonding, and the connecting protrusion 222 is used to align and plug the connecting hole 21 to rotatably connect the lens frame 11 and the connecting frame 12. The elastic support foot 221 can be elastically deformed in a direction away from the connecting hole 21 so that the connecting protrusion 222 moves out of the connecting hole 21. In this way, the elastic support foot 221 is rotatably connected to the connecting hole 21 through the connecting protrusion 222, thereby rotatably connecting the lens frame 11 and the connecting frame 12, and the elastic support foot 221 elastically deforms in the direction away from the connecting hole 21, which can drive the connecting protrusion 222 to move out of the connecting hole 21, and the rotational connection between the lens frame 11 and the connecting frame 12 can be disassembled. It can be seen that the rotational connection structure of the lens frame 11 and the connecting frame 12 is simple and easy to disassemble and assemble, which greatly saves the disassembly and assembly time, and the temples 13 and headbands can be freely replaced, and different styles of lens frames 11 can also be freely replaced, which effectively improves the application range of the detachable and replaceable glasses.

[0041] The elastic legs 221 can be integrally formed with the connecting frame 12 or the lens frame 11 using plastic. Thus, when the elastic legs 221 are subjected to force, they can be deformed by plastic bending, thereby driving the connecting protrusion 222 to move out of the connecting hole 21 .

[0042] See also Figure 1 , Figure 2 and Figure 3As shown, in an embodiment in which the lens frame 11 and the connecting frame 12 are rotatably connected, the lens frame 1 further includes an adapter block 23, the adapter block 23 has a limiting groove 231, and a connecting hole 21 is opened on the groove wall of the limiting groove 231. The lens frame 11 and the connecting frame 12 both include an elastic support foot 221 and a connecting protrusion 222. The elastic support foot 221 is plugged into the limiting groove 231, and the connecting protrusion 222 is connected to the elastic support foot 221 by integral connection or bonding, and the connecting protrusion 222 is used to align and plug the connecting hole 21. The elastic support foot 221 can be elastically deformed in a direction away from the connecting hole 21 so that the connecting protrusion 222 moves out of the connecting hole 21. When the lens frame 1 is unfolded, the elastic support foot 221 abuts against the bottom of the limiting groove 231 to limit the connecting frame 12 from rotating outward relative to the lens frame 11. In this way, when installing the lens frame 11 and the connecting frame 12, first, the elastic legs 221 of the lens frame 11 and the connecting frame 12 are respectively inserted into the two ends of the limiting groove 231, and force is applied to elastically deform the elastic legs 221 in a direction away from the connecting hole 21, so as to drive the connecting protrusion 222 to be inserted into the limiting groove 231 together. When the connecting protrusion 222 is opposite to the connecting hole 21, the elastic legs 221 are restored and drive the connecting protrusion 222 to be inserted into the connecting hole 21, so as to rotate the connecting adapter block 23 and the lens frame 11, and the connecting adapter block 23 and the lens frame 11 are connected. 3 and the connecting frame 12, thereby rotating and connecting the lens frame 11 and the connecting frame 12; on the contrary, when the lens frame 11 and the connecting frame 12 are disassembled, force is applied to make the elastic support foot 221 elastically deform in the direction away from the connecting hole 21, so as to drive the connecting protrusion 222 to move out of the limiting groove 231, and then the elastic support foot 221 of the lens frame 11 and / or the connecting frame 12 is pulled out of the limiting groove 231, so that the removed lens frame 11 and / or the connecting frame 12 can be replaced, and the disassembly and assembly is simple and fast, which greatly saves the disassembly and assembly time, so that the temples 13 and the headband can be freely replaced. After the lens frame 11 and the connecting frame 12 are installed, when the frame 1 is unfolded, the elastic support foot 221 abuts against the bottom of the limiting groove 231, so that the elastic support foot 221 cannot continue to rotate outward, so as to limit the rotation angle of the connecting frame 12 relative to the lens frame 11, and effectively prevent the connecting frame 12 from being over-expanded and affecting the wearing.

[0043] There are at least two elastic legs 221, wherein at least one elastic leg 221 is connected to the lens frame 11 by integral connection or bonding, and at least one elastic leg 221 is connected to the connecting frame 12 by integral connection or bonding. In this embodiment, there are two symmetrically distributed elastic legs 221 on the lens frame 11 and the connecting frame 12, and two symmetrically opened connecting holes 21 are formed at both ends of the transfer block 23 to ensure the connection stability of the lens frame 11 and the connecting frame 12, that is, when the elastic legs 221 are not subjected to a force of elastic deformation in a direction away from the connecting holes 21, the transfer part of the lens frame 11 and the connecting frame 12 will not be automatically disassembled.

[0044] See also Figure 3As shown, in one embodiment of the connecting protrusion 222 , the connecting protrusion 222 has an arc-shaped guide surface 223 , and the guide surface 223 is used to guide the elastic support foot 221 to elastically deform in a direction away from the connecting hole 21 so that the elastic support foot 221 can be inserted into or moved out of the limiting groove 231 . In this way, when the elastic support foot 221 is inserted into the limiting groove 231, the connecting protrusion 222 abuts against the groove wall of the limiting groove 231 through the guiding surface 223, and the guiding surface 223 can guide the elastic support foot 221 to deform elastically, so that the connecting protrusion 222 can be inserted into the limiting groove 231 along with the elastic support foot 221, until the connecting protrusion 222 is aligned and inserted into the connecting hole 21; and when the elastic support foot 221 moves out of the limiting groove 231, the guiding surface 223 can guide the elastic support foot 221 to deform elastically, so that the connecting protrusion 222 moves out of the connecting hole 21, thereby facilitating the elastic support foot 221 to move out of the limiting groove 231. It can be seen that the guiding surface 223 can facilitate the rapid disassembly and assembly of the transition between the lens frame 11 and the connecting frame 12, thereby further improving the disassembly and assembly efficiency of the detachable and replaceable glasses.

[0045] See also Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment in which the locking block 3 is slidably connected with the lens frame 11 or the connecting frame 12, the lens frame 11 and the connecting frame 12 are provided with a clearance groove 15 for the locking block 3 to be slidably inserted, and the upper and lower groove walls of the clearance groove 15 are provided with sliding protrusions 14 by bonding or integral connection, and the sliding protrusions 14 are used to be slidably connected with the locking block 3. In this way, the locking block 3 can be slidably connected with the lens frame 11 and / or the connecting frame 12 by sliding the sliding protrusions 14 into the clearance groove 15 to control whether the lens frame 11 and the connecting frame 12 are relatively fixed, and the upper and lower sides of the locking block 3 are slidably connected with the sliding protrusions 14, which effectively ensures the stability of the sliding process of the locking block 3 and prevents the locking block 3 from loosening. Among them, the clearance groove 15 can also facilitate the elastic support foot 221 to elastically deform into the clearance groove 15 to drive the connecting protrusion 222 to move out of the connecting hole 21.

[0046] In this embodiment, there are two symmetrically distributed elastic feet 221 on the lens frame 11 and the connecting frame 12, and the two symmetrical elastic feet 221 respectively form the upper and lower groove walls of the clearance groove 15, and the upper and lower sides of the locking block 3 have sliding grooves 31 for sliding connection with the sliding protrusion 14.

[0047] See also Figure 1 , Figure 2 and Figure 3 As shown, based on the above embodiment, the locking block 3 has a force-applying protrusion 32, and the force-applying protrusion 32 protrudes out of the clearance groove 15. In this way, the force-applying protrusion 32 can facilitate the user to apply force to slide the locking block 3 and easily switch the sliding position of the locking block 3.

[0048] See also Figure 1 , Figure 2 and Figure 4 As shown, Figure 4 1 is an exploded view of the structure of the lens holder and the nose pad in the embodiment. In one embodiment of the lens holder 11, the lens holder 11 includes a lens holder 111 and a nose pad 112. The lens holder 111 has a sliding portion 113 and a stopper 114. The bottom end of the sliding portion 113 is connected to the stopper 114 by integral connection or bonding. One side of the nose pad 112 has a hanging portion 115 that is slidably connected to the sliding portion 113. When the hanging portion 115 slides to the bottom end of the sliding portion 113, the hanging portion 115 abuts against the stopper 114. In this way, the nose pad 112 is slidably connected with the sliding portion 113 through the hanging portion 115, and can be hung on the lens seat 111, and the stop portion 114 can prevent the hanging portion 115 from sliding out from the bottom end of the sliding portion 113, ensuring that the nose pad 112 is not easy to fall off. It can be seen that the nose pad 112 and the lens seat 111 are connected by hanging, which can be easily disassembled and assembled, so that the nose pad 112 or the glasses lens can be freely replaced.

[0049] See also Figure 4 As shown, the hanging portion 115 is provided with a hanging groove 116 , which is matched with the sliding portion 113 , and the cross-sectional shape and size of the two are the same, so that the hanging portion 115 can be slidably hung on the lens holder 111 .
