Description

Technical Field

[0001] This utility model relates to the technical field of protective equipment, and in particular to a noise-reducing goggles. Background Technology

[0002] In many specific activity venues and work environments, such as shooting ranges, cycling tracks, logging areas, and construction sites, the protection needs of users are diverse and stringent.

[0003] From an eye protection perspective, these scenarios involve flying debris, such as shrapnel from a gun barrel during shooting, stones flying while cycling, wood chips falling during logging, and small particles raised during construction, all of which can easily damage the eyes. At the same time, strong light, especially ultraviolet rays and glare, can cause eye discomfort and even affect vision with prolonged exposure. Therefore, professional safety goggles are essential equipment. They must not only provide physical protection against impacts from foreign objects but also offer excellent UV protection and anti-glare capabilities to comprehensively safeguard eye safety.

[0004] In terms of ear protection, these places generally have extremely high levels of noise. The roar of gunfire during shooting, the whistling wind while cycling, the operation of logging machinery, and the hammering of construction tools, etc., can cause hearing damage if one is exposed to such high-decibel environments for a long time. Wearing earplugs has become a common and effective way to block noise and achieve physical noise reduction.

[0005] However, in actual use, existing protective equipment has revealed many problems. Traditional stand-alone earplugs are inconvenient to store and easily lost after being removed for audio communication, which undoubtedly increases the cost of use. While some earplugs that use connecting cords or pull cords to fix them have solved the problem of falling out, the cords swing behind the ears during use, which is not only unsightly but also poses a safety hazard, such as potentially tripping over other objects and causing injury to the user.

[0006] For example, patent document CN201173999Y discloses multifunctional special shooting glasses, and patent document CN213310869U discloses protective glasses for wood processing. Both have made certain improvements to the protective glasses, but the above-mentioned problems still exist.

[0007] Therefore, current protective equipment for these specific scenarios, whether it is goggles for eye protection or earplugs for ear protection, has varying degrees of defects. There is an urgent need for a new, comprehensive protective product to solve these problems and improve the protection and user experience in complex environments. Utility Model Content

[0036] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Please see Figures 1 to 7In this embodiment of the present invention, a noise-reducing goggles includes a frame 10 and temples 30. The temples 30 are hinged to both ends of the frame 10. A protective lens 20 is installed on the frame 10. A noise-reducing pendant 40 is installed on the temples 30. The noise-reducing pendant 40 is provided with an adjustment mechanism 50, a cotton thread (not shown in the figure), and a noise-reducing earplug 42. One end of the cotton thread is connected to the adjustment mechanism 50, and the other end is connected to the noise-reducing earplug 42. The adjustment mechanism 50 is installed on the temples 30 and adjusts the length of the cotton thread to release or retract the noise-reducing earplug 42.

[0038] Specifically, in shooting sports, cycling, logging, or construction work, users' eyes need protection to avoid injury from flying debris. Additionally, there are requirements for UV protection and glare reduction, necessitating the wearing of professional safety goggles. These locations also often experience significant noise levels, requiring the use of earplugs to effectively block out noise and achieve physical noise reduction.

[0039] Secondly, in shooting ranges, sports venues, or work environments, people need to communicate verbally, requiring them to remove their earplugs and put them back in afterward. Traditional stand-alone earplugs are inconvenient to store after removal, easily lost, and increase usage costs. Existing technologies also use connecting cords or pull cords to secure the earplugs and prevent them from falling off. However, during use, these cords are difficult to store, causing them to dangle behind the ears, which is unsightly and can even lead to accidents such as tripping over other objects and causing injury. Therefore, improvements are necessary.

[0040] Next, the adjustment mechanism 50 releases the noise-canceling earplug 42, which is equivalent to releasing the length of the cotton thread, making it longer so that the noise-canceling earplug 42 can be removed from the noise-canceling pendant 40, making it easier to extend and insert into the ear canal to achieve the noise-canceling effect. Then, the adjustment mechanism 50 retracts the noise-canceling earplug 42, which is equivalent to the user removing the earplug from the ear canal. Subsequently, the adjustment mechanism 50 retracts the length of the cotton thread, making it shorter so that the earplug is finally snugly attached to or stored on the noise-canceling pendant 40, making it more aesthetically pleasing and safer.

[0041] In addition, to facilitate the stretching and contraction of the cotton thread, an auxiliary sleeve 48 can be set inside the noise reduction pendant 40 and fixed between the base 44 and the top cover 43, so that the cotton thread can pass through the auxiliary sleeve 48 and move back and forth.

[0042] like Figures 6 to 7 As shown, preferably, an auxiliary pin 41 is provided between the cotton thread and the noise-canceling earplug 42. One end of the auxiliary pin 41 is fixed to the cotton thread, and the other end is replaceably fixed to the noise-canceling earplug 42.

[0043] Specifically, since the noise-canceling earplug 42 may become dirty after a period of use and need to be replaced, an auxiliary pin 41 can be provided. Utilizing its spiral structure, it can be spirally inserted into the tail end of the noise-canceling earplug 42, both securing the earplug and allowing for easy replacement when needed. The auxiliary pin 41 is preferably made of plastic, with a connector for the connecting thread at one end and a threaded tip at the other end for easy spiral insertion into the tail of the earplug. The noise-canceling earplug 42 is preferably made of silicone, utilizing the elastic deformation properties of silicone to effectively isolate noise. The thread of the auxiliary pin 41 is preferably designed to be coarse for easy manual rotation, and a recessed design can be provided at the tail of the earplug to facilitate the spiral insertion of the auxiliary pin 41.

[0044] like Figure 3 As shown, preferably, the noise-reducing pendant 40 is detachably fixed to the temple 30.

[0045] Specifically, the housing of the noise-canceling pendant 40 can be directly mounted and fixed to the temple 30, or it can be integrally molded onto the temple 30. For easy replacement in case of damage, it can also be detachably fixed to the temple 30. For example, a detachable connection can be formed using bolts and screw holes, or a snap-fit ​​connection can be used. Alternatively, a clamping arm can be provided on the noise-canceling pendant 40 to hold it onto the temple 30, forming a detachable fixed connection.

[0046] like Figures 3 to 4 As shown, preferably, the temple 30 is also provided with a hanging frame 31, which extends a certain distance from a part of the temple 30 to both sides to form a frame-like structure with internal storage space, for accommodating the noise-reducing hanging piece 40, and for detachably fixing the noise-reducing hanging piece 40 to the temple 30.

[0047] Specifically, the inner wall of the hanging frame 31 is provided with a slot 32, and the outer wall of the noise-reducing hanging part 40 is provided with a retaining strip 45 corresponding to the slot 32. The retaining strip 45 can be inserted into the slot 32 to form an interference fit, thereby forming a detachable and replaceable fixed connection. In order to make the noise-reducing hanging part 40 relatively securely attached to the hanging frame 31, it is preferable to provide three sets of slots 32 on the inner walls of the three sides of the hanging frame 31, and similarly, three sets of retaining strips 45 are provided on the outer wall of the noise-reducing hanging part 40. Thus, the three sets of slots 32 and the three sets of retaining strips 45 cooperate with each other to form a stable snap-fit ​​connection.

[0048] Secondly, in order to prevent the noise-reducing pendant 40 from coming off during use, it is preferable to set one end of the insertion opening of the slot 32 on the side of the temple 30 facing the user's head, and set the other end of the slot 32 with a limiting bottom wall 33, so that after the card strip 45 is inserted into the slot 32, it is restricted at the limiting bottom wall 33, preventing it from coming off from the other side of the temple 30.

[0049] like Figures 6 to 7 As shown, preferably, the noise reduction pendant 40 has a base 44 and a top cover 43. The adjustment mechanism 50 is installed in the base 44. The top cover 43 and the base 44 cooperate with each other and are fixedly connected to form an integral part. An extension guide post 46 is provided in the base 44. The adjustment mechanism 50 has a rotating cylinder 51. The rotating cylinder 51 is sleeved on the extension guide post 46 and forms a rotatable connection. One end of the cotton thread connecting the adjustment mechanism 50 is fixed to the rotating cylinder 51, thereby winding around the rotating cylinder 51.

[0050] Specifically, since one end of the cotton thread is fixed to the rotating drum 51, rotating the drum 51 winds the cotton thread around it. This rotation of the drum 51 allows adjustment of the thread length, thereby releasing or retracting the cotton thread onto the noise-canceling earplug 42. To rotate the drum 51, a rotating handle (not shown in the figure) can be provided, with one end connected to the drum 51 and the other end extending from the top cover 43, allowing the user to drive the rotation and adjust the thread length. Alternatively, a side hole (not shown in the figure) can be provided on the side wall of the base 44, allowing a portion of the outer periphery of the drum 51 to extend from the side hole, allowing the user to rotate the drum 51 by turning it through the side hole, thus adjusting the thread length.

[0051] Secondly, to prevent the cotton thread from being unintentionally stretched, a certain amount of damping can be applied to the rotation of the rotating drum 51. For example, a rubber ring, as is used in the prior art, can be added between the extension guide post 46 and the rotating drum 51 to achieve a certain damping effect. Alternatively, a rubber nozzle can be provided at the outlet of the cotton thread, with a thread passage hole in the middle, so that a certain damping effect is generated when the cotton thread passes through the thread passage hole. The fixed connection between the top cover 43 and the base 44 can be achieved by a snap-fit ​​connection or a bolt connection.

[0052] To use, first pinch the noise-canceling earplug 42 with your fingers and apply slight force to deform it. This applies the gripping force to the auxiliary pin 41, preventing damage from directly pulling the earplug. After firmly holding the auxiliary pin 41, apply a certain pull away from the noise-canceling pendant 40 to stretch the cotton thread to a certain length. Then, pinch the noise-canceling earplug 42 and insert it into the ear canal, allowing it to expand and fill the ear canal, achieving a physical noise reduction effect. When you need to use your ear canal to listen to sound, simply pinch the noise-canceling earplug 42 again and pull it out of the ear canal. If it is only temporarily removed, there is no need to retract the cotton thread. When you need to use the noise-canceling earplug 42 again, you can quickly reinsert it into the ear canal along the cotton thread. If the noise-canceling earplugs 42 will not be used for a relatively long period of time, the rotating handle can be turned or the side wall of the rotating cylinder 51 can be moved to make the rotating cylinder 51 rotate synchronously, winding the cotton thread to reduce its length and retract it until the noise-canceling earplugs 42 are attached tightly or stored on the noise-canceling pendant 40, making the whole thing more beautiful and safer.

[0053] like Figures 6 to 7 As shown, preferably, the adjusting mechanism 50 further includes a first elastic element 53, a stop element 54, a second elastic element 56, and a release element 57. One end of the first elastic element 53 is fixed to the extension guide post 46, and the other end is fixed to the rotating cylinder 51, thereby driving the rotating cylinder 51 to rotate around the extension guide post 46. One end of the stop element 54 is fixed to the rotating cylinder 51, and the other end facing the extension guide post 46 has an active tooth 55. One end of the release element 57 is sleeved on the extension guide post 46, and the other end facing the stop element 54 has a passive tooth 58. One end of the second elastic element 56 abuts against the base 44, and the other end abuts against the release element 57, thereby driving the passive tooth 58 of the release element 57 to cooperate with the active tooth 55 of the stop element 54 to form a ratchet mechanism.

[0054] Specifically, in the previous embodiment, the adjustment of the cotton thread was mainly done by manual rotation or flicking, which was not convenient or quick enough. Therefore, in this embodiment, a ratchet mechanism can be set to achieve automatic locking and one-click retraction of the cotton thread adjustment. The cotton thread is wound around the outer wall of the rotating drum 51, and a limiting ring is set at one end of the rotating drum 51. A corresponding limiting ring is also formed on the stop 54 at the other end, thereby limiting the winding of the cotton thread and preventing the cotton thread from slipping or deviating during the winding process. The rotating drum 51 is usually made of a rigid material so that the cotton thread can be wound and unwound stably.

[0055] The first elastic element 53 is preferably a coil spring, installed inside the rotating drum 51, providing the power for the rotating drum 51 to return to its original position. One end of the coil spring is fixed to the extension guide post 46, and the other end is fixed to the side wall of the rotating drum 51. When the rotating drum 51 rotates, the coil spring stores force, and after releasing the release member 57, it drives the rotating drum 51 to rotate in the opposite direction to retract the cotton thread. The driving tooth 55 of the stop member 54 and the driven tooth 58 of the release member 57 cooperate with each other to form a ratchet mechanism, which is used to control the rotation of the rotating drum 51.

[0056] Secondly, the release element 57 is fitted onto the extension guide post 46 and moves along its axial direction, thereby triggering the end face ratchet to lock or unlock. When retracting the cotton thread, pressing the button on the release element 57 along the axial direction of the rotating drum 51 pushes the passive tooth 58 to disengage from the active tooth 55 of the rotating drum 51, releasing the ratchet mechanism, removing the restriction on the rotation of the rotating drum 51, and the spring force drives the rotating drum 51 to rotate and retract the cotton thread. Through this ratchet mechanism, the adjusting mechanism 50 can achieve automatic locking and one-button return functions, which is simple and reliable to operate.

[0057] Furthermore, the active tooth 55 is configured as a plurality of radially arranged ratchet teeth distributed along the end face of the stop member 54, and the passive tooth 58 is configured as a plurality of radially arranged pawl teeth distributed along the end face of the release member 57, with the ratchet teeth and pawl teeth meshing with each other to form a ratchet mechanism. The second elastic member 56 is preferably configured as a common compression spring, whose elastic force drives the release member 57, causing it to always tend to lock the rotating drum member 51 without external force, preventing it from retracting. When the cotton thread is pulled, the rotating drum member 51 can be rotated, and at the same time, the active tooth 55 on the stop member 54, which is equivalent to a ratchet, also rotates synchronously, while the passive tooth 58 on the release member 57, which is equivalent to a pawl, can slide over the back of the active tooth 55; when released, the passive tooth 58 will fall into the groove of the active tooth 55, locking the stop member 54 and the rotating drum member 51 to prevent them from reversing, thereby realizing the automatic locking of the cotton thread. Along the extension direction from the base 44 to the top cover 43, the ratchet teeth are inclined counterclockwise, and the pawl teeth are inclined clockwise, thereby ensuring that the pawl teeth can slide over the back of the ratchet teeth when the cotton thread is pulled. The release element 57 is preferably a button-type structure, and the user only needs to press the release element 57 to disengage the pawl teeth from the ratchet teeth. After releasing the release element 57, the second elastic element 56 (compression spring) drives the release element 57 to reset.

[0058] In use, when it is necessary to retract the cotton thread, the release piece 57 can be pressed to unlock the engagement between the ratchet teeth and pawl teeth of the ratchet mechanism, thereby releasing the restriction on the rotating drum 51, allowing the coil spring to drive the rotating drum 51 to rotate and retract the cotton thread. When pulling the cotton thread outward, the ratchet mechanism can achieve a self-locking function. That is, once the release piece 57 is released, the compressed spring returns to its deformation, and its elastic force drives the release piece 57, causing the ratchet teeth and pawl teeth of the ratchet mechanism to re-engage. In other words, the ratchet mechanism will automatically re-lock the rotating drum 51, blocking its rotation and ensuring that it cannot retract, thus maintaining the current position of the cotton thread.

[0059] Furthermore, the connection between the stop 54 and the rotating cylinder 51 can be achieved using existing snap-fit ​​connections or by directly applying adhesive, forming a rotating integral assembly. A mounting through-hole is provided at the central axis of the rotating cylinder 51 to facilitate the assembly of the release element 57 and the compression spring. The rotating cylinder 51 has a fixing hole 52; after passing through the fixing hole 52, the cotton thread can be knotted inside the rotating cylinder 51 for positioning and fixation. To ensure smoother return and extension of the coil spring, a wear-resistant sheet 47 can be placed between the coil spring and the base 44 without damaging the base 44. For pressing the release element 57, a pressing through-hole can be provided on the top cover 43, allowing one end of the release element 57 to protrude from the pressing through-hole, forming a pressing part.

[0060] like Figures 1 to 4 As shown, preferably, the protective lens 20 is detachably installed in the arc-shaped groove 12 of the frame 10.

[0061] Specifically, in order to facilitate the disassembly and replacement of the lens, an arc-shaped groove 12 matching the curvature of the lens can be provided on the downward-facing side of the frame 10, and inverted grooves 13 are provided at both ends of the arc-shaped groove 12, so that the locking blocks 21 at both ends of the lens can be locked into the inverted grooves 13 to form a detachable fixed connection, which is convenient for users to disassemble or replace the lens multiple times.

[0062] Secondly, a slot 32 and a flexible accessory 14 are provided in the middle of the frame 10. The flexible accessory 14 is detachably connected to the slot 32. The flexible accessory 14 uses a molded hardware pin 15 process, injection molding the hardware pin 15 onto a relatively soft plastic accessory. A locking hole 22 is provided on the lens corresponding to the position of the hardware pin 15. After the lens is installed in the arc-shaped groove 12, it can be fastened to the frame 10 using the flexible accessory 14. The hardware pin 15, under the deformation of the flexible accessory 14, fits perfectly into the locking hole 22, thus providing auxiliary fixation for the lens installation. Furthermore, the hardware pin 15 is fixed to the flexible part of the flexible accessory 14 through injection molding, and the locking hole 22 is located in the non-optical area of ​​the lens to avoid obstructing vision.

[0063] like Figures 3 to 4 As shown, preferably, the goggles 20 are also provided with a nose bridge 25, which is detachably mounted on the goggles 20.

[0064] Specifically, a nose bridge 25 can be provided at the location where the lens corresponds to the user's nose wing to provide auxiliary support for wearing the lens. After long-term use, the nose bridge 25 may become deformed or dirty and need to be replaced. To facilitate future replacement, the nose bridge 25 can be fixed by bolt or snap-fit ​​connection. For example, a nose bridge notch 23 can be provided at the location where the lens corresponds to the nose bridge 25, and a protrusion 24 can be provided on the outer extension of the nose bridge notch 23. A recess 26 can be provided at the location of the nose bridge 25 corresponding to the protrusion 24, so that when the nose bridge 25 is installed in the nose bridge notch 23, the protrusion 24 fits into the recess 26, thus fixing the nose bridge 25. A limiting groove 27 can also be provided on the nose bridge 25, and the edge of the lens can fit into the limiting groove 27 to further enhance the stability of the nose bridge 25. The nose bridge 25 is manufactured using a two-color soft and hard plastic injection molding method. The side that connects to the lens is made of hard plastic injection molding, while the part that contacts the user's nose is made of soft plastic injection molding. This not only strengthens the installation structure of the nose bridge 25 but also improves the user experience.

[0065] like Figures 1 to 5 As shown, preferably, the two ends of the frame 10 are provided with pins, and the end of the temple 30 connected to the frame 10 is provided with a shaft hole, so that the temple 30 can cooperate with the pin through the shaft hole to form a hinge.

[0066] Specifically, to allow the temples 30 to retract or expand, pins can be installed at both ends of the frame 10, and these pins can be inserted into the shaft holes of the temples 30 to achieve a hinged connection, allowing the temples 30 to rotate relative to the frame 10. To prevent the temples 30 from rotating excessively and becoming inconvenient to use, limiting parts 11 can be installed at both ends of the frame 10 to limit and block the rotation of the temples 30, ensuring comfortable wearing. The limiting parts 11 are extensions on the frame 10 that cooperate with the missing parts of the temples 30 to limit the rotation angle of the temples 30 and ensure wearing stability.

[0067] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
