Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of protective glasses, and particularly relates to a lens quick mounting structure for protective glasses and protective glasses. BACKGROUND

[0002] Protective glasses can be used to prevent smoke, sand, external impact, chemical drugs or optical radiation from causing harm to the eyes of the wearer, and there are many types of these protective glasses, such as windshields, snowshields, etc.

[0003] Since protective glasses need to have the function of light transmission and protection, the frame structure of protective glasses is more complex than that of general glasses, and the cost is also higher.

[0004] However, since the lenses of protective glasses are prone to scratches during use, it often leads to the fact that the protective glasses have to be scrapped due to lens scratches even if the frame structure of the protective glasses can still be used, resulting in a lot of waste. The main reason for this phenomenon is that the replaceable lens technology of current protective glasses is not mature enough, and the lens mounting and dismounting structure is complex, which is difficult for users to operate. SUMMARY

[0005] In order to solve at least one of the above problems, according to one aspect of the utility model, a lens quick mounting structure for protective glasses is provided.

[0006] The lens quick mounting structure for protective glasses comprises a first frame body, the first frame body is used for being fixedly arranged opposite to the frame or being integrally formed; and a clamping structure arranged on the first frame body; wherein the clamping structure is arranged to be locked relative to the first frame body and unlocked from the first frame body when pressed; and the clamping structure is further arranged to clamp the lens between the frame and the clamping structure when it is locked relative to the first frame body; and the lens can be taken out from between the frame and the clamping structure when the clamping structure is unlocked relative to the first frame body.

[0007] When the lens needs to be replaced, the clamping structure only needs to be pressed to unlock the clamping structure relative to the first frame body, remove the old lens, and then clamp the new lens between the clamping structure and the first frame body through the clamping structure, so as to realize the quick replacement of the lens. Since the clamping structure needs to be unlocked by pressing, the stability of the protective glasses in use can be ensured.

[0008] In some embodiments, the clamping structure comprises a clamping block hinged to the first frame body and movable relative to the first frame body about the first pivot axis between a first position and a second position; and a pressing block movably arranged on the first frame body relative to the first frame body along the extension direction of the first pivot axis between a first engagement position and a second engagement position; wherein the clamping block and the pressing block are arranged such that, when the clamping block is in the first position and the pressing block is in the first engagement position, the clamping block and the pressing block are engaged to lock the clamping structure relative to the first frame body; and / or the clamping block and the pressing block are further arranged such that, when the pressing block is in the second engagement position, the clamping block and the pressing block are disengaged to unlock the clamping structure relative to the first frame body.

[0009] In this way, whether the pressing block and the clamping block are engaged can be controlled by controlling the positions of the pressing block and the clamping block, so as to control the timing of locking and unlocking of the clamping structure relative to the first frame body.

[0010] In some embodiments, the first frame body is provided with a first through hole arranged along the extension direction of the first pivot axis; the pressing block passes through the first through hole and is formed with a pressing protrusion outside the first frame body, and the pressing protrusion is arranged such that, by pressing the pressing protrusion along the extension direction of the first pivot axis, the pressing block can be moved from the first engagement position to the second engagement position.

[0011] In this way, by pressing the pressing protrusion, the pressing block can be moved from the first engagement position to the second engagement position, so as to realize the disengagement of the clamping block and the pressing block, i.e. the unlocking of the clamping structure relative to the first frame body.

[0012] In some embodiments, the pressing block is arranged to have a tendency to move from the second engagement position to the first engagement position. In this way, under the action of no external force, the pressing block remains in the first engagement position, so as to ensure the stability of the engagement of the pressing block and the clamping block, i.e. the stability of the locking of the clamping structure relative to the first frame body.

[0013] In some embodiments, the first through hole is arranged at the bottom of the first frame body. In this way, the pressing block can have a tendency to move from the second engagement position to the first engagement position under the action of its own gravity; and the first through hole arranged at the bottom of the first frame body is less likely to be touched during use, so as to avoid the unlocking of the clamping structure due to accidental touching.

[0014] In some embodiments, the tendency of the pressing block to move from the second engagement position to the first engagement position is achieved in that the lens quick mounting structure for the protective eyewear further comprises a first elastic member; the first elastic member is arranged to be elastically deformed by the external force applied by the pressing block when the pressing block moves from the first engagement position to the second engagement position. Since the first elastic member is elastically deformed when the pressing block is in the second engagement position, the first elastic member has a tendency to restore its original shape, and thus the first elastic member has a tendency (a driving force) to drive the pressing block to move from the second engagement position to the first engagement position, i.e. the pressing block is kept in the first engagement position by the first elastic member in the absence of external force, so as to stably engage the pressing block with the clamping block when the clamping block is in the first position.

[0015] In some embodiments, the clamping structure further comprises a second elastic member arranged to have a tendency to move the clamping block from the first position to the second position. Thus, when the clamping structure is unlocked from the first frame body, the clamping block is moved from the first position to the second position by the second elastic member, so as to take out the lens from between the clamping structure and the frame.

[0016] In some embodiments, the second elastic member is a torsion spring, a first leg of the torsion spring abuts against a side of the first frame body facing the clamping block, and a second leg of the torsion spring abuts against a side of the clamping block facing the first frame body. Thus, the clamping block has a tendency to move from the first position to the second position by means of a simple structure.

[0017] In some embodiments, the pressing block comprises a pressing column movably arranged on the first frame body along the extension direction of the first pivot axis between the first engagement position and the second engagement position, and a first protrusion arranged on one side of the pressing column; the clamping block comprises a clamping plate hingedly arranged on the first frame body by the first pivot axis, a first connecting column arranged on a side of the clamping plate facing the pressing block, and a second protrusion extending from the first connecting column along the extension direction of the first pivot axis to a side facing the first protrusion, so as to be engaged in the first recess when the clamping block is in the first position and the pressing block is in the first engagement position.

[0018] Thus, when the second protrusion is engaged in the first recess, the movement of the clamping block from the first position to the second position can be limited, so as to ensure the stability of the locking of the clamping structure with the first frame body.

[0019] In some embodiments, the first frame body is provided with a first guide rail extending along the direction of the first pivot axis, and the pressing block is provided with a first sliding block matched with the first guide rail. In this way, the stability of the movement of the pressing block relative to the first frame body along the extension direction of the first pivot axis can be ensured by the first guide rail and the first sliding block.

[0020] According to another aspect of the present application, a protective eyewear is provided.

[0021] The protective eyewear comprises a lens, a frame and the aforementioned lens quick mounting structure for the protective eyewear; wherein the first frame body of the lens quick mounting structure is fixedly arranged relative to the frame or first formed; and the lens is detachably connected to the frame through the lens quick mounting structure. In this way, the lens can be quickly replaced through the lens quick mounting structure; and since the clamping structure needs to be unlocked by pressing, the stability of the use of the protective eyewear can be ensured.

[0022] In some embodiments, the side of the clamping block of the lens quick mounting structure facing the frame is further provided with a third protrusion; and the lens is provided with a second groove matched with the third protrusion at a position corresponding to the third protrusion, so that when the clamping block is in the first position and the lens is clamped between the clamping block and the frame, the third protrusion is matched in the second groove. In this way, when the lens is clamped between the clamping block and the frame, the lens can be further prevented from shaking relative to the clamping block and the frame through the mutually matched third protrusion and second groove, so as to ensure the stability of the installation of the lens.

[0023] In some embodiments, the frame is provided with a first magnetic attraction member; and the lens is provided with a second magnetic attraction member at a position corresponding to the first magnetic attraction member, and the lens and the frame are magnetically connected through the first magnetic attraction member and the second magnetic attraction member.

[0024] In this way, when the clamping structure is unlocked relative to the frame and / or the first frame body, the lens and the frame can be magnetically connected through the second magnetic attraction member and the first magnetic attraction member, so as to prevent the lens from falling off, thereby facilitating the locking and unlocking operation of the clamping structure without the need for manually holding the lens; and since the lens is also magnetically connected to the frame, in combination with the clamping structure, the stability of the connection between the lens and the frame can be further ensured.

[0025] In some embodiments, the lens comprises a lens body and a lens frame, and at least one of the lens body, the second magnetic attraction member and the second groove is arranged on the lens frame. Since the lens body is generally thin, it is difficult and unstable to arrange the second magnetic attraction member and the second groove on the lens body, and the lens frame is introduced in the present application to facilitate the stable integration of the lens body, the second magnetic attraction member and the second groove, thereby reducing the processing difficulty of the lens and ensuring the long service life of the lens.

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] Figures 1 to 4 A lens quick mounting structure for protective eyewear according to an embodiment of the present application is schematically shown.

[0039] As shown in Figure 3 and Figure 4 , the lens quick mounting structure for protective eyewear includes a first frame body 20, a clamping block 32 and a pressing block 33. The first frame body 20 can be fixedly arranged relative to the eyewear frame 40, or can be integrally formed with the eyewear frame 40, i.e. the first frame body 20 is also the eyewear frame 40. The clamping block 32 is hinged on the first frame body 20 through a first pivot shaft 31, so as to be capable of rotating relative to the first frame body 20 about the first pivot shaft 31 between a first position (as shown in Figure 1 and Figure 2 ) and a second position (as shown in Figure 3 and Figure 4The pressing block 33 can move relative to the first frame body 20 between a first engaging position (as shown in Figure 1 and Figure 2 a second engaging position (as shown in Figure 3 and Figure 4 When the clamping block 32 is in the first position and the pressing block 33 is in the first engaging position, the clamping block 32 is engaged with the pressing block 33, so that the clamping block 32 is locked relative to the first frame body 20 and can clamp the lens 50 between the frame 40 and the clamping block 32 (as shown in Figure 5 When the pressing block 33 is in the second engaging position, whether the clamping block 32 is in the first position or the second position, the clamping block 32 is separated from the pressing block 33, so that the clamping block 32 is unlocked relative to the first frame body 20, and at this time, the lens 50 can be taken out from between the frame 40 and the clamping block (as shown in Figure 6 and Figure 7 .

[0040] When the lens 50 needs to be replaced, only the pressing block 33 needs to be pressed to move the pressing block 33 from the first engaging position to the second engaging position, so that the clamping block 32 and the pressing block 33 are unlocked (as shown in Figure 3 , Figure 4 , Figure 6 and Figure 7 , so that the old lens 50 can be taken out from between the clamping block 32 and the frame 40, and the new lens 50 can be placed between the clamping block 32 and the frame 40; Then, move the clamping block 32 to the first position and move the pressing block 33 to the first engaging position to lock the clamping block 32 and the pressing block 33 (as shown in Figure 1 , Figure 2 and Figure 5 , so as to clamp the new lens 50 between the clamping block 32 and the frame 40. Since the lens quick mounting structure of the present application is provided on the frame 40, the locking and unlocking operation between the clamping block 32 and the pressing block 33 can quickly and conveniently realize the replacement of the lens 50; Moreover, since the pressing block 33 needs to be pressed to move the pressing block 33 from the first engaging position to the second engaging position, the unlocking between the clamping block 32 and the pressing block 33 can be realized, which can avoid the misoperation when wearing protective glasses and ensure the stability of the protective glasses.

[0041] In some embodiments, as shown in Figure 3 and Figure 4 , the first pivot shaft 31, the clamping block 32 and the pressing block 33 constitute the clamping structure 30 of an embodiment of the present application. The clamping structure 30 is locked relative to the first frame body 20 when the clamping block 32 and the pressing block 33 are relatively locked, and is unlocked relative to the first frame body 20 when the clamping block 32 and the pressing block 33 are relatively unlocked.

[0042] As one of the embodiments that the pressing block 33 can move between the first matching position and the second matching position along the direction of the first pivot axis 31 relative to the first frame body 20, as shown in Figure 2 The first frame body 20 is integrally formed or processed with the first through hole 21 arranged along the direction of the first pivot axis 31; the pressing block 33 passes through the first through hole 21 and forms the pressing protrusion 3311 outside the first frame body 20. Preferably, the pressing protrusion 3311 is arranged such that the pressing block 33 can move from the first matching position to the second matching position by pressing the pressing protrusion 3311 along the direction of the first pivot axis 31. That is, by arranging the length of the pressing protrusion 3311 protruding out of the first frame body 20, the pressing block 33 can move from the first matching position to the second matching position by pressing the pressing protrusion 3311 along the direction of the first pivot axis 31.

[0043] As another embodiment that the pressing block 33 can move between the first matching position and the second matching position along the direction of the first pivot axis 31 relative to the first frame body 20, as shown in Figures 1 to 4 The first frame body 20 is integrally formed, processed or connected with the first guide rail 22 extending along the direction of the first pivot axis 31, and the pressing block 33 is integrally formed, processed or connected with the first sliding block 333 adapted to the first guide rail 22.

[0044] In some embodiments, as shown in Figures 1 to 4 The locking of the pressing block 33 and the clamping block 32 is achieved by that the pressing block 33 includes the pressing column 331 and the first protrusion 332 integrally formed, processed or connected on one side of the pressing column 331, the pressing column 331 is movably arranged on the first frame body 20 along the direction of the first pivot axis 31 between the first matching position and the second matching position, and the side of the first protrusion 332 away from the clamping block 32 is integrally formed or processed with the first recess 3321; the clamping block 32 includes the clamping plate 321 hinged on the first frame body 20 through the first pivot axis 31, the first connecting column 322 integrally formed, processed or connected on the side of the clamping plate 321 facing the pressing block 33, and the second protrusion 323 extending on the first connecting column 322 along the direction of the first pivot axis 31 towards the side where the first protrusion 332 is located. Thus, when the clamping block 32 is in the first position and the pressing block 33 is in the first matching position, the second protrusion 323 is engaged in the first recess 3321 to limit the movement of the clamping block 32 from the first position to the second position, thereby achieving the locking of the clamping block 32 and the pressing block 33.

[0045] In some embodiments, the press block 33 is movably arranged on the first frame body 20 along the extension direction of the first pivot axis 31 between the first engagement position and the second engagement position. For the implementation of the press block 33 movably arranged on the first frame body 20 along the extension direction of the first pivot axis 31 between the first engagement position and the second engagement position, reference can be made to the implementation of the press block 33 movably arranged on the first frame body 20 along the extension direction of the first pivot axis 31 between the first engagement position and the second engagement position, which will not be repeated herein.

[0046] In some preferred embodiments, the press block 33 is arranged to have a tendency to move from the second engagement position to the first engagement position. Thus, under the action of no external force, the press block 33 remains in the first engagement position, so as to ensure the stability of the engagement of the press block 33 with the clamping block 32, i.e. the stability of the locking of the clamping structure 30 with the first frame body 20.

[0047] As one of the embodiments in which the press block 33 has a tendency to move from the second engagement position to the first engagement position, as shown in Figure 2 the first through hole 21 is arranged at the bottom of the first frame body 20. Thus, the press block 33 can maintain the tendency to move from the second engagement position to the first engagement position under the action of its own gravity; and the first through hole 21 arranged at the bottom of the first frame body 20 is less likely to be touched during use, avoiding the unlocking of the clamping structure 30 due to accidental touching.

[0048] As another embodiment in which the press block 33 has a tendency to move from the second engagement position to the first engagement position, as shown in Figures 1 to 3 the lens quick mounting structure for protective eyewear further comprises a first elastic member 34; the first elastic member 34 is arranged to be elastically deformed by the external force applied by the press block 33 when the press block 33 moves from the first engagement position to the second engagement position.

[0049] As one of the embodiments of the first elastic member 34, as shown in Figures 1 to 3 the first elastic member 34 is a compression spring, one end of the compression spring abuts against the press block 33, and the other end abuts against the first frame body 20; when the press block 33 is moved from the first engagement position to the second engagement position along the direction Y under the action of external pressure, the compression spring is compressed to be elastically deformed by the pressure of the press block 33, and the compression spring which has been elastically deformed has a tendency to restore its original shape; when the external force acting on the press block 33 is removed, the compression spring restores its original shape while driving the press block 33 to move from the second engagement position to the first engagement position.

[0050] As another embodiment of the first elastic member 34, the first elastic member 34 is a tension spring, one end of which is connected with the pressing block 33, and the other end of which is connected with the first frame body 20. When the pressing block 33 is moved from the first matching position to the second matching position along the direction Y under the external pressure, the tension spring is stretched to produce elastic deformation under the action force of the pressing block 33, and the tension spring which has produced elastic deformation has a tendency to restore the original shape. When the external force acting on the pressing block 33 is removed, the tension spring restores the original shape while driving the pressing block 33 to move from the second matching position to the first matching position.

[0051] As one preferred embodiment of the clamping structure 30, as shown in Figure 3 and Figure 4 , the clamping structure 30 further comprises a second elastic member 35, which is arranged to have a tendency to drive the clamping block 32 to move from the first position to the second position. Thus, when the clamping structure 30 is unlocked from the first frame body 20, the clamping block 32 is driven by the second elastic member 35 to move from the first position to the second position, so as to facilitate the lens 50 to be taken out from between the clamping structure 30 and the frame 40.

[0052] As one embodiment of the second elastic member 35, as shown in Figure 3 and Figure 4 , the second elastic member 35 is a torsion spring, a first leg 351 of which abuts against one side of the first frame body 20 facing the clamping block 32, and a second leg 352 of which abuts against one side of the clamping block 32 facing the first frame body 20. Thus, the clamping block 32 has a tendency to move from the first position to the second position by means of a simple structure.

[0053] Figures 5 to 7 A protective eyewear according to an embodiment of the present application is schematically shown.

[0054] As shown in Figures 5 to 7 , the protective eyewear comprises a lens 50, a frame 40, and the aforementioned lens quick mounting structure for the protective eyewear. The first frame body 20 of the lens quick mounting structure can be fixedly arranged relative to the frame 40, or can be integrally formed with the frame 40, i.e., the first frame body 20 is also the frame 40. The lens 50 is detachably connected to the frame 40 through the lens quick mounting structure. The lens 50 is quickly replaced through the lens quick mounting structure; and since the clamping structure 30 needs to be pressed to be unlocked, the stability of the protective eyewear in use can be ensured.

[0055] In some preferred embodiments, as shown in Figure 6As shown, the side of the clamping block 32 of the lens quick mounting structure facing the frame 40 is also integrally formed, processed or connected with a third protrusion 324; the lens 50 is integrally formed or processed with a second groove 521 corresponding to the third protrusion 324, which is adapted to the third protrusion 324, so that when the clamping block 32 is in the first position and the lens 50 is clamped between the clamping block 32 and the frame 40, the third protrusion 324 is adapted in the second groove 521. When the lens 50 is clamped between the clamping block 32 and the frame 40, the mutually adapted third protrusion 324 and second groove 521 can further prevent the lens 50 from shaking relative to the clamping block 32 and the frame 40, thereby ensuring the stability of the lens 50 mounting.

[0056] In some preferred embodiments, as shown in Figure 6 and Figure 7 As shown, the frame 40 is provided with a first magnetic attraction member 41; the lens 50 is provided with a second magnetic attraction member 522 corresponding to the first magnetic attraction member 41, and the lens 50 and the frame 40 are magnetically connected through the first magnetic attraction member 41 and the second magnetic attraction member 522. When the clamping structure 30 is unlocked relative to the frame 40 and / or the first frame body 20, the lens 50 and the frame 40 are magnetically connected through the second magnetic attraction member 522 and the first magnetic attraction member 41, so as to avoid the lens 50 from falling off, thereby facilitating the locking and unlocking operation of the clamping structure 30 without the need to hold the lens 50 by hand; and since the lens 50 is also magnetically connected with the frame 40, in combination with the clamping structure 30, the stability of the connection between the lens 50 and the frame 40 can be further ensured.

[0057] In some preferred embodiments, as shown in Figures 5 to 7 As shown, the lens 50 comprises a lens body 51 and a lens frame 52, and at least one of the lens body 51, the second magnetic attraction member 522 and the second groove 521 is arranged on the lens frame 52. By introducing the lens frame 52, the lens body 51, the second magnetic attraction member 522 and the second groove 521 can be stably integrated, thereby reducing the processing difficulty of the lens 50 and ensuring the long service life of the lens 50.

[0058] In the present application, connection or mounting is fixed connection without special emphasis. The fixed connection can be realized as detachable connection or non-detachable connection commonly used in the prior art. The detachable connection can be realized by the prior art, such as threaded connection or key connection. The non-detachable connection can also be realized by the prior art, such as welding or gluing.

[0059] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the creative concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
