Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to a pair of eyeglasses with detachable temples. Background Technology

[0002] Eyeglasses, as common devices for correcting vision, protecting the eyes, or enhancing appearance, typically consist of a frame, lenses, and temples attached to both ends of the frame. Currently, the connection between the temples and frames in most eyeglasses on the market falls into two main categories: fixed connections and detachable connections. Fixed connections often employ bolt fastening, welding, or a one-piece molding design. While this structure ensures the stability of the connection between the temples and frame, it has significant drawbacks in practical use: when the temples are damaged and need replacement, or when users need to disassemble the temples for different scenarios (such as storage or carrying), specialized tools such as screwdrivers must be used to remove the small bolts one by one, a tedious and time-consuming process. Furthermore, repeated bolt removal can lead to stripped bolts and worn threads, ultimately damaging the connection structure of the frame or temples, shortening the overall lifespan of the eyeglasses, and incurring additional maintenance costs for the user.

[0003] To address the inconvenience of assembling and disassembling fixed-connection eyeglasses, some manufacturers have developed eyeglasses with quick-detachable temples. These products typically utilize simple connection structures such as clips and slots to achieve rapid assembly and disassembly of the temples from the frame. However, existing quick-detachment structures generally suffer from insufficient strength in restricting the temples: to facilitate quick assembly and disassembly, the fitting gaps in the connection structure are usually large, and there is a lack of effective pre-tightening and limiting mechanisms. As a result, during daily wear, the temples are prone to loosening or even separating from the frame due to external forces such as head movements or accidental impacts. This not only affects the stability of the glasses but may also cause the temples or frame to fall and be damaged, failing to meet users' basic requirements for the reliability of eyeglasses. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a type of eyeglass with detachable temples. This solves the problems of cumbersome disassembly and assembly of traditional eyeglasses frames and temples, requiring the removal of numerous small bolts to separate the temples from the frame, and the low limiting strength of traditional quick-detachable eyeglasses, which causes the temples to easily separate from the frame during wear.

[0005] To achieve the above objectives, this utility model provides a pair of eyeglasses with detachable temples, including a frame and two temples respectively disposed at both ends of the frame. The temples are detachably connected to the frame by a connecting assembly, which includes a base plate and a mounting base. Either the mounting base or the base plate is connected to the temple, and the other is connected to the frame. The mounting base has a socket that is swayably disposed thereon. A pre-tightening member is provided between the socket and the mounting base for applying a pre-tightening force to the socket to make the socket and the mounting base relatively parallel. The socket has a slot for inserting the base plate. A limiting structure is provided between the mounting base and the base plate for restricting the movement of the base plate to prevent the base plate from falling out of the slot when the socket and the mounting base are relatively parallel. When the socket and the mounting base are relatively parallel, the temples and the frame are relatively perpendicular.

[0006] The advantages of adopting the above technical solution are: the connecting component enables a detachable connection between the temple and the frame without removing small bolts, simplifying the disassembly and assembly process and facilitating temple replacement and eyeglass storage; the base plate and mounting seat can flexibly connect the temple or the frame, improving structural adaptability; the swing-mounted socket, in conjunction with the pre-tightening component, can maintain the socket and mounting seat relatively parallel through pre-tightening force, ensuring a stable wearing angle with the temple and frame relatively perpendicular, preventing temple angle deviation during wear; and the socket slot facilitates quick insertion of the base plate, improving assembly efficiency. The limiting structure restricts the movement of the base plate when the socket and mounting seat are parallel, effectively preventing the base plate from falling out of the slot, solving the problem of low limiting strength in traditional quick-disassembly eyeglasses, balancing ease of disassembly and assembly with connection stability, and preventing accidental separation of the temple and frame during wear.

[0007] This utility model further comprises: the end wall of the socket's starting end and the inner wall of the socket are connected by a smooth inclined surface and form a mating surface; the mating surface is inclined relative to the inner wall of the mounting base; the mating surface and the inner wall of the mounting base are in clearance fit and form a swing gap for providing swing space for the socket when a force is applied to the starting end of the socket in the direction of the mounting base; the pre-tightening member includes a pre-tightening spring piece, which is made of elastic material and consists of a force-bearing part and a deformation part; the force-bearing part is connected and fitted with the socket; the deformation part is abutted and fitted with the mounting base; and the deformation part and the force-bearing part are connected by a smooth arc surface.

[0008] The advantages of adopting the above technical solution are as follows: the mating surface and swing gap at the beginning of the socket provide a stable swing space for the socket when a force is applied to the beginning of the socket towards the mounting base, facilitating the rotation of the socket during operation and helping the base plate to be inserted and removed smoothly. The force-bearing part of the pre-tightening spring is connected to the socket, ensuring that the pre-tightening force is effectively transmitted to the socket. The deformation part abuts against the mounting base to stably provide the pre-tightening force, maintaining the parallel state of the socket and the mounting base. Furthermore, the smooth arc surface connection of the pre-tightening spring reduces stress concentration when the deformation part is under force, extending the service life of the spring. The elastic material ensures the durability and reset capability of the pre-tightening force, preventing the spring from weakening due to fatigue failure, thus improving the overall ease of operation and structural durability of the connection component.

[0009] The present invention further comprises: a first receiving groove is provided on the inner wall of the mounting base for partially accommodating the end of the deformable part; the end of the deformable part is abutting and cooperating with the bottom wall of the first receiving groove; a second receiving groove is provided on the mating surface for accommodating the force-bearing part; and the force-bearing part is connected to the bottom wall of the second receiving groove.

[0010] The advantages of adopting the above technical solution are: the first groove of the mounting base accommodates the end of the deformable part, which can position the deformable part and prevent it from shifting when it is deformed under force, ensuring the stability of the pre-tightening force direction and avoiding the pre-tightening effect being affected; while the second groove of the socket mating surface accommodates the force-bearing part, making the force-bearing part and the socket more tightly connected, reducing loosening and ensuring the effective transmission of force.

[0011] The present invention further includes the following: the limiting structure includes a first locking block disposed on the inner wall of the mounting base; the socket is provided with a first locking groove for engaging with the first locking block when the socket and the mounting base are relatively parallel; the first locking groove is connected to the slot; and a second locking groove is provided on the base plate corresponding to the position of the first locking groove for partially engaging the end of the first locking block when the socket and the mounting base are relatively parallel.

[0012] The advantages of adopting the above technical solution are: the first locking block of the mounting base and the first locking block of the socket engage when parallel, initially limiting the relative position of the socket and the mounting base, preventing the socket from swinging accidentally. Moreover, the first locking groove is connected to the slot, allowing the first locking block to extend into the slot and engage with the second locking groove of the substrate, forming a three-way limiting double locking engagement, which greatly improves the limiting strength and effectively prevents the substrate from falling out of the slot. The locking structure can be released by simply swinging the socket during disassembly and assembly, without increasing the difficulty of operation. It takes into account both the reliability of limiting and the convenience of disassembly and assembly, avoids the substrate from loosening and separating due to external force during wearing, and ensures stable connection.

[0013] The present invention further includes the following: the limiting structure includes a second locking block disposed at the end of the base plate, and a third locking groove is provided on the inner wall of the mounting base for engaging with the second locking block when the socket and the mounting base are relatively parallel.

[0014] The advantages of adopting the above technical solution are: the second locking block at the end of the substrate and the third locking slot of the mounting base engage when parallel, directly limiting the substrate from the connection end of the substrate and the mounting base, restricting the movement of the substrate along the length of the slot, specifically preventing the substrate from coming out of the end of the slot, and the locking structure is simple, requiring no complex parts, reducing structural complexity and failure risk, and the locking can be released by swinging the socket during disassembly and assembly, which is simple to operate and does not affect disassembly and assembly efficiency. While ensuring the limiting effect, it improves structural reliability and production assembly efficiency, and reduces maintenance costs.

[0015] The present invention further includes: the inner wall of the socket is evenly distributed with pressing protrusions along the length of the socket to assist external users in pressing the socket, and the pressing protrusions are arranged in a wave shape.

[0016] The advantages of adopting the above technical solution are: the wave-shaped pressing protrusions on the inner wall of the socket are evenly distributed along the length, which increases the friction when pressing, prevents fingers from slipping, improves the operating feel, and evenly transmits the pressing pressure to the socket, preventing excessive local force from causing the socket to deform. It also ensures that the force is balanced when the socket swings, making it easier to control the swing amplitude and accurately operate the board insertion and removal.

[0017] The present invention is further provided that the mounting base is connected with connecting bolts for detachable connection with the frame or temple of the mirror.

[0018] The advantages of adopting the above technical solution are: the connecting bolts of the mounting base enable a detachable connection between it and the frame or temple, allowing for individual replacement of damaged components without the need to replace the entire pair of glasses, thus reducing maintenance costs. Furthermore, the high bolt connection strength ensures a stable connection between the mounting base and the component, preventing loosening. It also facilitates adjustment during assembly, adapting to different frame or temple sizes and improving product versatility. Disassembly and assembly require only conventional tools, without increasing complexity, balancing connection stability, ease of maintenance, and product compatibility, thereby extending the overall lifespan of the glasses. To further enhance the connection strength between the mounting base and the temple or frame, grooves can be created in the frame or temple to partially embed the mounting base, which is then fixed using bolts, thereby reducing space requirements and improving applicability.

[0019] The present invention further includes a pin at the end of the substrate for detachable connection with the frame or temple of the mirror.

[0020] The advantages of adopting the above technical solution are: the pin at the end of the substrate enables a detachable connection with the frame or temple, which is easy to assemble, does not require complex threaded fit, reduces assembly difficulty, improves production efficiency, and the pin structure is simple and durable, not easy to fail due to frequent disassembly and assembly, ensuring long-term connection stability, and taking into account assembly convenience, wearing comfort and maintenance economy.

The socket 4 has a slot 41 for inserting the base plate 2. A mechanism is provided between the mounting base 3 and the base plate 2 to restrict the movement of the base plate 2 when the socket 4 is relatively parallel to the mounting base 3 to prevent... The limiting structure prevents the base plate 2 from exiting the slot 41. When the socket 4 is parallel to the mounting base 3, the temple 11 is perpendicular to the frame 1. The starting end wall of the socket 4 is connected to the inner wall of the socket 4 with a smooth inclined surface and a mating surface 42 is formed. The mating surface 42 is inclined relative to the inner wall of the mounting base 3.

[0025] Specific embodiment 1 of the above technical structure: Overall operation process of detachable temple eyeglasses (taking the mounting base on the temple and the base plate on the frame as an example):

[0026] I. Assembly Process:

[0027] 1. In the initial state, the pre-tightening component (such as the pre-tightening spring) applies a pre-tightening force to the socket, keeping the socket and the mounting base relatively parallel. At this time, the temple is in a vertical preparatory state to be connected to the frame; the base plate on the frame is in an insertable state, and the slot and limiting structure (first locking block and first slot, second locking block and third slot) on the socket are in the initial engagement position, and there is no external force applied when pressing the protrusion.

[0028] 2. During assembly, the user applies force to the pressing protrusion to tilt the socket relative to the mounting base. Then, the base plate on the frame is aligned with the slot of the socket in the temple mounting base. After the mating surface is subjected to force, the socket rotates around the swing fulcrum of the mounting base. At this time, the beginning end of the socket obtains swing space through the swing gap. The socket tilts against the pre-tightening force of the pre-tightening member, and the slot opening widens, making it easier for the base plate to be continuously inserted. Then, a pushing force is applied to the base plate towards the slot until the base plate and the slot are mated. After the base plate is fully inserted into the slot, the pushing force is removed, the deformed part of the pre-tightening member returns to its original position, and the force-bearing part pushes the socket back to its initial position, so that the socket and the mounting base are relatively parallel again. At the same time, the limiting structure takes effect: the first locking block on the inner wall of the mounting base engages with the first locking slot of the socket and extends into the slot to engage with the second locking slot of the base plate. The second locking block at the end of the base plate simultaneously engages with the third locking slot on the inner wall of the mounting base. The double limiting restricts the movement of the base plate and prevents it from coming out of the slot. The temple and the frame remain relatively perpendicular, and the assembly is completed.

[0029] II. Wearing Process: During wear, the temples remain stably connected to the frame via the connecting components. The limiting structure continues to function, and the engagement of the first locking block and the slot, and the second locking block and the third slot remain unchanged, preventing the base plate from dislodging from the slot due to head movement, minor collisions, or other external forces. The pre-tightening component constantly applies pre-tightening force to the socket, maintaining the parallelism between the socket and the mounting base, ensuring that the temples always maintain a wearing angle perpendicular to the frame, and preventing temple misalignment from affecting wearing comfort. The pressing protrusions on the inner wall of the socket do not come into contact with external forces and do not interfere with the wearing process. The overall structure remains stable, enabling the glasses to be worn normally.

[0030] III. Disassembly Procedure: During disassembly, the user presses their fingers against the wavy protrusions on the inner wall of the socket, applying pressure towards the mounting base. The protrusions evenly transmit the force to the socket, causing it to overcome the pre-tightening force of the pre-tightening component and rotate around the pivot point. The socket and mounting base are no longer parallel, and the swing gap provides room for movement again. During the rotation of the socket, the locking state of the limiting structure is released: the first locking block disengages from the first locking slot and the second locking slot of the base plate, and the second locking block disengages from the third locking slot. Then, a pulling force away from the temple is applied to the frame, causing the base plate to be pulled out of the socket slot, completing the separation of the frame and temple. After disassembly, the pressing pressure is removed, the pre-tightening component is reset, and the socket is pushed back to be parallel with the mounting base, ready for the next assembly.

[0031] The swing connection structure between the socket and the mounting base described above is prior art. It can be a shaft and a rotating block structure. Specifically, the mounting base has a protrusion with a through hole for insertion or threaded engagement with the shaft, allowing the shaft to be detachably connected to the mounting base. The rotating block is mounted on the socket and has a through hole for the shaft to pass through and rotate, and a through groove for the protrusion to engage. This allows the rotating block to swing relative to the mounting base via the shaft, thus achieving relative swinging between the socket and the mounting base. This swing connection structure is prior art, and a hinged connection can also be used. Since it is prior art, its structure and function will not be described in detail. The shaft is designated as 6 in the accompanying drawings, the rotating block structure as 61, and the through hole as 62.

[0032] The accompanying drawings in the above instruction manual are only schematic diagrams of the positions of each component and do not limit the actual shape and size. They can be adapted to meet actual assembly and production requirements. At the same time, the accompanying drawings only show the positions of the connecting bolts. The connection position between the bolts and the mounting base can be adjusted according to actual needs. The connection method between the bolts and the mounting base is a threaded connection. Since threaded connections are existing technology, their structure and function will not be described in detail.

[0033] The above instruction manual is attached Figure 3 The pre-tightening component is adjusted by optimizing the pre-tightening spring into a pre-tightening spring based on actual assembly and operating conditions. The pre-tightening spring can also achieve pre-tightening force loading and reset conditions. The pre-tightening spring is selected as the second implementation method. One end of the pre-tightening spring is connected to the bottom wall of the second cavity, and the other end abuts against the bottom wall of the first cavity. In this way, when the socket swings, the pre-tightening spring is compressed and deformed to generate mechanical force. This mechanical force can drive the socket to swing and reset. At the same time, it will continue to apply pre-tightening force to the socket after the socket resets. Through the above structural optimization, it can be adapted to different applicable working conditions and operating conditions. The pre-tightening spring is marked as 7 in the attached drawings of the specification.

[0034] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
