Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to an assembled safety eyeglass. Background Technology

[0002] Safety glasses are eye protection equipment. Their core function is to resist impact and block external interference during sports, while adapting to the needs of sports to ensure vision and comfort. They are widely used in various sports such as basketball, football, skiing, cycling, and badminton.

[0003] Chinese Taiwan patent TW099213409 discloses a structural improvement of safety glasses, which mainly includes a frame, lenses and temples. The frame has a fitting edge and a locking body at the bottom, and the upper edge of the frame has a pivot seat and a reinforcement at both ends, with a locking part formed in the reinforcement. The lenses have locking bodies and bent extensions for eye protection on both sides.

[0004] The safety glasses described above are designed to only block wind from blowing into the eyes from above. They are suitable for wearing during certain sports and can achieve a safety effect, but they fail to provide wind protection from below, which can still cause wind to blow into the eyes. This is especially true in high-speed sports such as skiing and cycling, where they cannot meet the comprehensive wind protection needs during sports.

[0005] For users who frequently participate in various sports, the aforementioned single structure is insufficient to meet the convenient need for "one lens for multiple scenarios." They typically equip themselves with multiple pairs of safety glasses corresponding to different sports. This not only significantly increases the user's economic costs but also requires the separate storage of multiple pairs of glasses when exercising outdoors, thus adding an extra burden to sports preparation and travel. Utility Model Content

[0006] To meet users' needs for a single pair of glasses that can be used in multiple scenarios, this application provides an assembly-type safety glasses.

[0007] The assembled safety glasses provided in this application adopt the following technical solution:

[0008] An assemblable safety glasses includes a lens, an upper frame, and two temples, as well as a lower frame with a lower windproof surface. The upper frame has an upper windproof surface, and both the upper and lower windproof surfaces are designed to fit snugly against the user's face. The lens is detachably connected to the upper frame. The two temples are hinged to both sides of the upper frame, and each side of the upper frame has a threaded hole. Both sides of the lower frame are rotatably connected to force-applying blocks. Threaded rods that can be threaded into the threaded holes are coaxially and fixedly connected to the two force-applying blocks. The lower frame has a lower recess that can be inserted into the lens. When the lower frame is installed on the upper frame, the lower recess engages with the lens, and the two threaded rods are threaded into the two threaded holes.

[0009] By adopting the above technical solution, the design of detachable lenses from the upper frame and detachable lower frame from the upper frame allows users to change different eyeglass structures according to different sports needs, eliminating the need to carry multiple pairs of glasses, reducing economic costs and carrying burden.

[0010] Preferably, it also includes screws, an upper recess is provided on the upper frame, a first through hole is provided on the upper recess, and a second through hole is provided on the lens. When the lens is installed on the upper frame, the lens is inserted into the upper recess, and the screw passes through the first through hole and the second through hole in sequence and is threaded onto the upper frame.

[0011] By adopting the above technical solution, the dual connection method of upper groove positioning and screw fixing reduces the possibility of the lens loosening or falling off during violent movement, and reduces the possibility of lens displacement due to impact in a single fitting structure.

[0012] Preferably, sealing strips are provided on both sides of the upper and lower grooves in the thickness direction. When the lens is inserted into the upper or lower groove, the sealing strips in the upper or lower groove abut against both sides of the lens in the thickness direction.

[0013] By adopting the above technical solution, the sealing strips of the upper and lower grooves abut against both sides of the lens, which can fill the gap between the frame and the lens, reducing the possibility of air leakage between the upper and lower frames and the lens.

[0014] Preferably, the lens strap is also included. The lens strap is detachably connected to the temple. Both ends of the lens strap in the length direction are provided with Velcro. The rounded and burred surfaces of the Velcro are arranged adjacent to each other. The two temples have through slots at their tail ends away from the upper frame. When the lens strap is installed on the temple, both ends of the lens strap can pass through the two through slots respectively and be wrapped around the temple, so that the rounded and burred surfaces of the Velcro are in contact.

[0015] By adopting the above technical solutions, the lens strap is detachable and adjustable via Velcro, meeting the fixation needs of multiple scenarios. For example, when skiing or cycling, the lens strap is needed to help fix the lens and prevent it from slipping, while for sports such as basketball and badminton, the lens strap can be removed to reduce the restriction, achieving "one lens for multiple uses". The Velcro design allows users to quickly attach and detach the lens strap, and the tightness can be adjusted according to the head circumference, taking into account both stability and comfort in different sports scenarios.

[0016] Preferably, one of the temples includes a hinge and a tool. The hinge is hinged to the upper frame and has a mounting groove. The groove is located on the tool and a screwdriver is fixedly connected to the tool. The tool is threadedly connected to the mounting groove. When the tool is threadedly connected to the hinge, the screwdriver is located in the mounting groove.

[0017] By adopting the above technical solution, the temples integrate a screwdriver tool, eliminating the need for additional tools when changing lenses. This makes it suitable for on-site lens adjustments or replacements during outdoor activities, enhancing the practicality of "one pair of glasses for multiple scenarios." The tool section can be stored in the hinge, without affecting normal wear of the glasses, avoiding the burden of carrying extra tools and enhancing product portability.

[0018] Preferably, the upper lens frame has a positioning hole on the downward side, and the lower lens frame has a positioning pin that matches the positioning hole on the upward side. When the threaded rod is threadedly connected to the threaded hole, the positioning pin is inserted into the positioning hole.

[0019] By adopting the above technical solution, the cooperation between the positioning pin and the positioning hole ensures that the lower frame and the upper frame are completely aligned during installation. The positioning structure also shares the force of the threaded rod, reducing the wear and tear on the threaded connection caused by sports impacts and extending the service life of the glasses in sports of different intensities such as basketball and skiing.

[0020] Preferably, the force-applying block has multiple force-applying grooves, which are evenly distributed around the circumferential surface of the force-applying block.

[0021] By adopting the above technical solution, the force-applying groove of the force-applying block increases friction, allowing users to easily twist the threaded rod to disassemble and assemble the lower frame even when wearing gloves or with sweaty hands, facilitating quick switching of protection modes according to sports scenarios. This simplifies disassembly and assembly operations, making it easier for users to replace parts.

[0022] Preferably, the upper and lower windproof surfaces are each provided with a rubber strip that can fit against the user's face.

[0023] By adopting the above technical solution, rubber strips that can fit the face are set on the upper and lower windproof surfaces. With the help of the elasticity of the rubber, the glasses adapt to different facial contours, fill the gap between the frame and the face, enhance the windproof effect, improve the wearing stability, reduce the displacement of glasses during sports, and adapt to the dynamic changes of the face in various sports scenarios. Combined with the overall design, it can achieve "one lens for multiple uses".

[0024] The main technical effects of this utility model are reflected in the following aspects:

[0025] 1. The design of this utility model, in which the lens and upper frame are detachable and the lower frame and upper frame are detachable, allows users to change lenses with different characteristics according to different sports needs, eliminating the need to carry multiple pairs of glasses, thus reducing economic costs and carrying burden.

[0026] 2. The eye strap of this utility model is detachable and adjustable by Velcro, which can meet the fixation needs of multiple scenarios. For example, when skiing or cycling, the eye strap is needed to help fix it and prevent it from slipping. When playing sports such as basketball and badminton, the eye strap can be removed to reduce the restriction and achieve "one eye for multiple uses". The Velcro design allows users to quickly remove and install the eye strap, and the tightness can be adjusted according to the head circumference, taking into account the stability and comfort in different sports scenarios.

[0027] 3. This utility model integrates a screwdriver tool into the temple of the glasses, eliminating the need for additional tools when changing lenses. It is suitable for on-site adjustment or replacement of lenses during outdoor sports, enhancing the practicality of "one pair of glasses for multiple scenarios." The tool can be stored in the hinge, without affecting the normal wearing of the glasses, avoiding the burden of carrying extra tools, and enhancing the product's portability.
