Description

Technical Field

[0001] This application relates to the field of photographic equipment technology, and more specifically, to a press-fit quick-installation lens frame. Background Technology

[0002] Camera filters are optical accessories mounted on the outside of camera lenses. They are mainly used to adjust the characteristics of incident light to achieve exposure control, color correction, or special visual effects. Their basic structure includes a frame for mounting the filter elements and the filter elements themselves mounted within the frame. The frame is used to fit and mount the filter to the front of the camera lens; the ease of its installation and removal directly affects the efficiency of the device and the user experience.

[0003] Currently, for lenses with threaded mounts, most filter frames are screwed onto the lens mount using a threaded structure that matches the lens mount. In actual installation, the threads of the filter frame need to be precisely aligned with the threads on the lens mount, and then tightened by rotating several turns to complete the installation. Removal involves unscrewing the filter frame in the reverse direction. The applicant has found in practice that the aforementioned process is cumbersome and time-consuming, the threaded structure is prone to jamming during engagement, and frequent tightening can even damage the threads of the camera mount.

[0004] Therefore, there is an urgent need for a frame solution that is easy to install and remove for filters that are compatible with threaded lenses. Utility Model Content

[0005] To address the shortcomings of the existing technology, the purpose of this application is to provide a press-type quick-install eyeglass frame, comprising an eyeglass frame with a first sliding groove and a second sliding groove respectively formed at opposite ends of the side of the eyeglass frame. A first fastener is disposed inside the first sliding groove and slides radially with the eyeglass frame. A second fastener is disposed inside the second sliding groove and slides radially with the eyeglass frame. The front surface of the first fastener has a first protrusion that engages with the inner edge of the lens interface, and the first protrusion has a first external thread that engages with the internal thread of the inner edge of the lens. The front surface of the second fastener has a second protrusion that engages with the inner edge of the lens interface, and the second protrusion has a second external thread that engages with the internal thread of the inner edge of the lens. An elastic element is disposed inside the eyeglass frame that contacts the first and second fasteners, for elastically opening the first and second fasteners radially.

[0006] Preferably, the first fastener has a first limiting block formed outward at both its left and right ends, and a first limiting groove is provided in the first sliding groove to slide and cooperate with the first limiting block; the second fastener has a second limiting block formed outward at both its left and right ends, and a second limiting groove is provided in the second sliding groove to slide and cooperate with the second limiting block.

[0007] Preferably, the first limiting block has a first baffle formed outward at the end away from the first fastener, and a first blocking surface that cooperates with the first baffle is provided in the first limiting groove, which is used to block and limit the first limiting block as it slides radially outward along the frame; the second limiting block has a second baffle formed outward at the end away from the second fastener, and a second blocking surface that cooperates with the second baffle is provided in the second limiting groove, which is used to block and limit the second limiting block as it slides radially outward along the frame.

[0008] Preferably, the back of the first fastener is provided with a plurality of first guide grooves, and a first guide rail is formed inside the first guide groove that slides and engages with the first guide groove; the back of the second fastener is provided with a plurality of second guide grooves, and a second guide rail is formed inside the second guide groove that slides and engages with the second guide groove.

[0009] Preferably, the transverse cross-sections of the first guide groove and the first guide rail are T-shaped / dovetail-shaped, and the transverse cross-sections of the second guide groove and the second guide rail are T-shaped / dovetail-shaped.

[0010] Preferably, the end of the first fastener away from the center of the frame is formed with a first anti-slip ridge, and the end of the second fastener away from the center of the frame is formed with a second anti-slip ridge.

[0011] Preferably, the elastic element includes a first wire-formed spring and a second wire-formed spring, and the first wire-formed spring and the second wire-formed spring are mirror-symmetrical arc shapes; the axial directions of the first wire-formed spring and the second wire-formed spring are parallel to the axial direction of the frame, and the two ends of the first wire-formed spring and the second wire-formed spring respectively elastically abut against each other, and the abutment points respectively cooperate with the first fastener and the second fastener.

[0012] Preferably, the frame includes a first frame body, and a second frame body is inserted inside the first frame body. The first frame body and the second frame body are assembled and fixed by a transition fit. The first frame body and the second frame body cooperate to form an annular space coaxial with the frame body, and the first wire forming spring and the second wire forming spring are placed in the annular space.

[0013] Preferably, one end of the first wire-formed spring and the second wire-formed spring after they are engaged abuts against the midpoint of the end of the first fastener near the center of the frame, and the other end of the first wire-formed spring and the second wire-formed spring after they are engaged abuts against the midpoint of the end of the second fastener near the center of the frame.

[0014] In summary, the beneficial effects of this application are as follows:

[0015] Pressing the first and second fasteners together brings them close together, allowing the first and second protrusions to be inserted into the lens. Releasing the press and using the restoring force of the elastic element, the threads engage and secure the lens. Disassembly is similar; simply press the first and second fasteners to separate the first and second external threads from the internal threads along the lens's inner edge, then pull out the first and second protrusions to complete the disassembly. This simplifies installation and disassembly, reduces relative friction wear between the threads, lowers the risk of jamming due to wear, and extends the lifespan of the frame and lens. It effectively solves the current problem where most filter frames use a threaded structure that matches the lens interface. While this threaded installation method achieves basic fixation, in practice, the frame threads need to be precisely aligned with the lens interface threads, requiring multiple turns to tighten. Disassembly involves reverse screwing, and the threaded structure can also jam due to wear caused by frequent rotation and friction during engagement. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0031] Press-to-install quick-install frame, see [link / reference] Figures 1 to 10The lens includes a frame 1. A first groove 2 and a second groove 3 are respectively provided at opposite ends of the side of the frame 1. A first fastener 4 is provided inside the first groove 2, sliding radially with the frame 1. A second fastener 5 is provided inside the second groove 3, sliding radially with the frame 1. The front surface of the first fastener 4 has a first protrusion 8 that engages with the inner edge 7 of the lens interface 6, and the first protrusion 8 has a first external thread 10 that engages with the internal thread 9 of the inner edge 7 of the lens. The front surface of the second fastener 5 has a second protrusion 11 that engages with the inner edge 7 of the lens interface 6, and the second protrusion 11 has a second external thread 12 that engages with the internal thread 9 of the inner edge 7 of the lens. An elastic element 13 is provided inside the frame 1, contacting the first fastener 4 and the second fastener 5, for elastically opening the first fastener 4 and the second fastener 5 radially. By simultaneously driving the first fastener 4 and the second fastener 5 closer to each other, in this process, the first protrusion 8 and the second protrusion 5... The two protrusions 11 move synchronously under the drive of the first fastener 4 and the second fastener 5, and the first fastener 4 and the second fastener 5 will simultaneously apply pressure to the elastic element 13, thereby causing the elastic element 13 to undergo elastic deformation and generate elastic restoring force. When the first protrusion 8 and the second protrusion 11 can be inserted into the lens interface 6 at the same time, the pressure on the first fastener 4 and the second fastener 5 can be stopped. Then, the first protrusion 8 and the second protrusion 11 are inserted into the lens interface 6 and the first external thread 10 and the second external thread 12 are threadedly aligned with the internal thread 9 of the inner edge 7 of the lens. Finally, the pressure applied to the first fastener 4 and the second fastener 5 is simultaneously released. At this time, the elastic element 13 will synchronously drive the first fastener 4, the first protrusion 8, the second fastener 5 and the second protrusion 11 to elastically reset, thereby causing the first external thread 10 and the second external thread 12 to simultaneously engage with the internal thread 9 of the inner edge 7 of the lens, thereby realizing the installation of the lens frame 1 into the lens interface 6.

[0032] Simply drive the first fastener 4 and the second fastener 5 simultaneously again, and move the first protrusion 8 and the second protrusion 11 closer to each other, thereby applying pressure to the elastic element 13 again and causing it to undergo elastic deformation, thus generating elastic restoring force. During this process, the first external thread 10 and the second external thread 12 will simultaneously separate from the internal thread 9 of the inner edge 7 of the lens. Then, pull the first protrusion 8 and the second protrusion 11 out of the lens interface 6 to remove the lens frame 1 from the lens interface 6. Finally, release the pressure applied to the first fastener 4 and the second fastener 5. At this time, the first fastener 4 and the second fastener 5 will elastically reset under the action of the elastic element 13.

[0033] Through the cooperation of the above structures, this embodiment eliminates the need for cumbersome multi-turn thread alignment and rotation operations. Simply pressing the first fastener 4 and the second fastener 5 together brings them close enough to insert the first protrusion 8 and the second protrusion 11 into the lens. Releasing the pressure and using the restoring force of the elastic element 13 achieves thread engagement and fixation. Similarly, disassembly only requires pressing the first fastener 4 and the second fastener 5 to separate the first external thread 10 and the second external thread 12 from the internal thread 9 of the inner edge 7 of the lens, then pulling out the first protrusion 8 and the second protrusion 11 to complete disassembly. This not only simplifies the installation and disassembly steps but also reduces the number of screws. The relative frictional wear between the threads reduces the risk of jamming due to wear, extends the service life of the frame 1 and the lens, and effectively solves the current problem that most filter frames 1 are screwed to the lens interface 6 using a threaded structure that matches the lens interface. Although the screw-in installation method of the threaded structure can achieve basic fixing function, in actual installation, the threads of the frame 1 need to be precisely aligned with the threads at the lens interface 6, and then rotated many times to tighten to complete the installation. When disassembling, the frame 1 is screwed in the opposite direction. In addition, the threaded structure can also get stuck due to wear caused by frequent rotation and friction during screwing.

[0034] The first fastener 4 has first limiting blocks 14 formed outwards at both its left and right ends, and a first limiting groove 15 that slides and engages with the first limiting blocks 14 is provided in the first sliding groove 2; the second fastener 5 has second limiting blocks 16 formed outwards at both its left and right ends, and a second limiting groove 17 that slides and engages with the second limiting blocks 16 is provided in the second sliding groove 3; a first baffle 18 is formed outwards at the end of the first limiting block 14 away from the first fastener 4, and a first blocking surface 19 that engages with the first baffle 18 is provided in the first limiting groove 15. The first limiting block 14 is used to block and limit the travel of the first limiting block 14 as it slides radially outward along the frame 1; the second limiting block 16 has a second baffle 20 formed outward at the end away from the second fastener 5, and a second blocking surface 21 that cooperates with the second baffle 20 is provided in the second limiting groove 17, which is used to block and limit the travel of the second limiting block 16 as it slides radially outward along the frame 1; in this embodiment, the sliding cooperation between the first limiting block 14 and the first limiting groove 15 can effectively limit the radial sliding of the first fastener 4 in the first sliding groove 2. The first fastener 4 is positioned to prevent displacement. The sliding engagement between the second limiting block 16 and the second limiting groove 17 effectively limits the radial sliding of the second fastener 5 within the second sliding groove 3, preventing displacement. When the first fastener 4 elastically resets to the point where the first baffle 18 abuts against the first blocking surface 19, this indicates the limit position of the first fastener 4's reset. The interaction between the first baffle 18 and the first blocking surface 19 further restricts the radial outward sliding of the first limiting block 14 along the frame 1. The process is blocked and limited; when the second fastener 5 elastically resets to the point where the second stop plate 20 abuts against the second blocking surface 21, it indicates that this is the limit position of the reset of the second fastener 5, and through the mutual cooperation between the second stop plate 20 and the second blocking surface 21, the travel of the second limiting block 16 sliding radially outward along the frame 1 is blocked and limited; through the mutual cooperation between the above structures, the second fastener 5 can be prevented from falling off the frame 1 due to excessive sliding during radial sliding, effectively ensuring the stability of installation and disassembly operations.

[0035] The back of the first fastener 4 is provided with multiple first guide grooves 22, and the first guide groove 2 is formed inside the first guide rail 23 that slides with the first guide groove 22; the back of the second fastener 5 is provided with multiple second guide grooves 24, and the second guide groove 3 is formed inside the second guide rail 25 that slides with the second guide groove 24; the transverse cross-section of the first guide groove 22 and the first guide rail 23 is T-shaped / dovetail-shaped, and the transverse cross-section of the second guide groove 24 and the second guide rail 25 is T-shaped / dovetail-shaped; in this embodiment, the upper and lower ends of the first guide groove 22 respectively penetrate the first guide groove 23. The first fastener 4 and the second guide groove 24 pass through the second fastener 5 at their upper and lower ends respectively. Since the cross-sections of the first guide groove 22, the first guide rail 23, the second guide groove 24, and the second guide rail 25 are all T-shaped or dovetail-shaped, the first guide groove 22 and the first guide rail 23 form a sliding fit, and the second guide groove 24 and the second guide rail 25 form a sliding fit. This not only effectively prevents the first fastener 4 and the second fastener 5 from falling off the side of the frame 1 with the first sliding groove 2 and the second sliding groove 3, but also further improves the stability of the first fastener 4 and the second fastener 5 when sliding radially.

[0036] The first fastener 4 has a first anti-slip ridge 26 formed at the end away from the center of the frame 1, and the second fastener 5 has a second anti-slip ridge 27 formed at the end away from the center of the frame 1. In this embodiment, by pressing the first anti-slip ridge 26 and the second anti-slip ridge 27 simultaneously, the first fastener 4 and the second fastener 5 can be driven to move closer to each other. The first anti-slip ridge 26 and the second anti-slip ridge 27 provide a reliable point of force for the pressing operation. The first anti-slip ridge 26 and the second anti-slip ridge 27 can effectively increase the friction between the force-applying party and the first fastener 4 and the second fastener 5, avoiding slippage during the pressing process, thereby making it easier and more stable to drive the first fastener 4 and the second fastener 5 closer to each other simultaneously.

[0037] The elastic element 13 includes a first wire-formed spring 1301 and a second wire-formed spring 1302, and the first wire-formed spring 1301 and the second wire-formed spring 1302 are mirror-symmetrical arc shapes; the axial directions of the first wire-formed spring 1301 and the second wire-formed spring 1302 are parallel to the axial direction of the frame 1, and the two ends of the first wire-formed spring 1301 and the second wire-formed spring 1302 respectively elastically abut against each other, and the abutment points respectively cooperate with the first fastener 4 and the second fastener 5; one end of the first wire-formed spring 1301 and the second wire-formed spring 1302 after cooperation abuts against the midpoint of the end of the first fastener 4 near the center of the frame 1, and the first wire-formed spring 1301 and the second wire-formed spring 1302 are... The other end of the fastener is engaged with the midpoint of the end of the second fastener 5 near the center of the lens frame 1. In this embodiment, when the first fastener 4 and the second fastener 5 move closer to each other, they will simultaneously drive the two ends of the first wire forming spring 1301 and the two ends of the second wire forming spring 1302 to move closer to each other and undergo elastic deformation, thereby generating an elastic restoring force. The elastic restoring force can drive the first fastener 4 and the second fastener 5 to perform elastic reset, thereby ensuring that the first external thread 10 and the second external thread 12 are tightly engaged with the internal thread 9 of the inner edge 7 of the lens and providing support for their engagement. At the same time, the arc-shaped structure adapts to the internal spatial layout of the lens frame 1, making the elastic deformation and reset process of the first wire forming spring 1301 and the second wire forming spring 1302 smoother.

[0038] The eyeglass frame 1 includes a first frame 101, and a second frame 102 is inserted inside the first frame 101. The first frame 101 and the second frame 102 are assembled and fixed together by a transition fit. The first frame 101 and the second frame 102 cooperate to form an annular space 103 coaxial with the eyeglass frame 1, and the first wire-formed spring 1301 and the second wire-formed spring 1302 are placed in the annular space 103. In this embodiment, it is only necessary to first install the first fastener 4 and the second fastener 5 on the first frame 101, and then place the first wire-formed spring 1301 and the second wire-formed spring 1302 on the first frame 101. The back of the first frame 101 is inserted so that the ends of the first wire-formed spring 1301 and the second wire-formed spring 1302 are elastically abutted. Finally, the second frame 102 is inserted from the back of the first frame 101, thereby confining the first wire-formed spring 1301 and the second wire-formed spring 1302 within the annular space 103 between the first frame 101 and the second frame 102. By providing the annular space 103, the movement and reset range of the first wire-formed spring 1301 and the second wire-formed spring 1302 can be limited, preventing the elastic element 13 from affecting the movement and reset effect of the first fastener 4 and the second fastener 5 due to displacement during use.

[0039] The above embodiments are merely explanations of this application and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
