TECHNICAL FIELD

[0001] The application belongs to the technical field of glasses cleaning equipment, and particularly relates to a frame glasses fixing structure and a glasses cleaning device. BACKGROUND

[0002] Frame glasses generally need to be cleaned once after being worn for one or two days, so that the glasses are bright and clear, and a clean and fresh face is maintained. In the existing ultrasonic glasses cleaning device, a certain amount of cleaning solution of detergent needs to be added into the cleaning tank first, and then the frame glasses are put into the cleaning tank. After ultrasonic cleaning, the glasses in the cleaning solution are taken out by hand. The hand is wet, and the glasses are also wet. The hand needs to be dried, and the glasses also need to be dried. The whole process is relatively troublesome. With the development and progress of technology, automatic glasses cleaning machines will also go from the laboratory to life, realizing a convenient cleaning process with both hands free.

[0003] Frame glasses are generally expensive. In the automatic cleaning process, if the frame glasses are not fixed well, they are easy to move or slide, which may cause the paint on the surface of the frame to be worn or even cause the surface film of the lens to be scratched.

[0004] In the glasses cleaning process, a large amount of cleaning solution is sprayed in the glasses cleaning device to flush the surface of the glasses. The environment is very humid, which causes the internal electronic components of the frame glasses fixing structure to be damaged. SUMMARY

DETAILED DESCRIPTION

[0040] The present invention will be described in further detail below with reference to the embodiments and accompanying drawings.

[0041] Example 1:

[0042] One embodiment of the present invention is a frame glasses fixing mechanism, such as Figures 1 to 3 As shown, it includes a supporting bracket, a rotating pressure piece, a driving unit, a transmission unit and a connecting piece.

[0043] The support bracket is used to support the frame glasses upward. The support bracket includes a nose bridge and temple supports. The nose bridge supports the nose bridge of the frame glasses. The temple supports support the temples of the frame glasses when they are open. The nose bridge and temple supports support the frame glasses through three contact points (one nose bridge contact point and two temple contact points), forming a stable support structure.

[0044] The supporting bracket is fixedly connected to the connecting piece. The nose bridge support and the temple support can be fixedly connected to the connecting piece respectively, such as in a T-shaped structure. The nose bridge support and the temple support can also be fixedly connected and then fixed to the connecting piece.

[0045] The rotating pressing piece is switched between the first position and the second position relative to the leg holder by rotating around the rotating shaft. When the rotating pressing piece is in the first position, the rotating pressing piece is separated from the frame glasses on the supporting bracket, facilitating the taking and placing of the frame glasses; when the rotating pressing piece is in the second position, the rotating pressing piece presses against the legs of the frame glasses on the supporting bracket, so as to fix the frame glasses in the cleaning process on the supporting bracket.

[0046] The driving unit is arranged above the supporting bracket and the rotating pressing piece to avoid the humid cleaning environment. The driving unit is connected with the supporting bracket through the connecting piece and drives the transmission unit to drive the rotating pressing piece to be switched between the first position and the second position relative to the leg holder. The driving unit can be arranged outside the glasses cleaning device, for example, the driving unit is arranged at the top of the glasses cleaning device, and the supporting bracket is arranged inside the glasses cleaning device and fixedly connected with the top of the glasses cleaning device through the connecting piece. Preferably, the driving unit is an electric motor.

[0047] The connecting piece is a hollow pipe and is closed to prevent water, cleaning solution or moisture from entering the horizontal hollow pipe or the vertical hollow pipe. Preferably, the connecting piece comprises the vertical hollow pipe and the horizontal hollow pipe. The horizontal hollow pipe is perpendicular to the vertical hollow pipe and is in internal communication with the vertical hollow pipe.

[0048] The transmission unit is arranged inside the connecting piece and transmits the output of the driving unit to the rotating pressing piece, so as to drive the rotating pressing piece to be switched between the first position and the second position relative to the leg holder. The output shaft of the transmission unit serves as the rotating shaft of the rotating pressing piece.

[0049] Preferably, the transmission unit comprises a worm and a worm wheel, as shown in Figure 2 The worm wheel is arranged in the horizontal hollow pipe, and the worm is arranged in the vertical hollow pipe. The worm wheel is engaged with the worm, the worm wheel shaft is arranged along the center line of the worm wheel and serves as the output shaft of the transmission unit, that is, the rotating shaft of the rotating pressing piece, and is sealed in the horizontal hollow pipe, for example, the two sides of the worm wheel are connected with sealing covers, which play the roles of limiting and waterproofing. In this embodiment, the worm wheel and the worm wheel shaft are integrally formed. One end of the worm is connected with the output shaft of the driving unit, and the other end is engaged with the worm wheel through the worm teeth. The vertical hollow pipe is internally provided with a step, which plays the roles of supporting and axially limiting the worm. The worm is rotated under the driving of the driving unit, so as to drive the worm wheel to rotate around the worm wheel shaft in the horizontal hollow pipe, thereby driving the rotating pressing piece to be switched between the first position and the second position.

[0050] It can be understood that, in the frame glasses fixing structure of the present application, the transmission unit can also be a sprocket and a chain arranged inside the connecting piece, or a gear or a rack arranged inside the connecting piece.

[0051] Preferably, the transverse hollow tube is located on both sides of the vertical hollow tube, respectively; the bottom end of the vertical hollow tube is connected to the support bracket (the nose bridge and the temple support), and the top end is connected to the top of the glasses cleaning device, which can greatly reduce the structural size of the connecting part of the connecting member and the support bracket, thereby further reducing the obstruction and influence of the frame glasses fixing structure on the water flow in the water washing process and the air flow in the air drying process, and the driving unit will not be damaged due to moisture, greatly improving the safety factor, and also reducing the process difficulty of the support bracket. Preferably, the top end of the vertical hollow tube protrudes out of the glasses cleaning device, which plays a waterproof role.

[0052] Preferably, the rotating pressure piece includes a rotating arm and an elastic piece, one end of the rotating arm is connected to the output shaft of the transmission unit, and the other end of the rotating arm is fixedly connected to the elastic piece, as shown in Figures 1 to 3 The driving unit drives the transmission unit to rotate the rotating arm around the rotating shaft of the rotating pressure piece, thereby driving the elastic piece to contact or separate from the temple of the frame glasses.

[0053] Preferably, the middle part of the elastic piece is fixed to the rotating arms on both sides of the output shaft of the transmission unit, which has the advantage that the middle part of the elastic piece is fixed by two rotating arms, which can make the elastic piece more stable during rotation. Alternatively, two elastic pieces are connected to two rotating arms, respectively, which has the advantage that the elastic piece is not blocked by the nose bridge, and the rotating arm can drive the elastic piece to rotate and press the temple more tightly, which is beneficial to the pressing and fixing.

[0054] The elastic force generated by the deformation of the elastic piece can stably keep the frame glasses on the support bracket, and the contact points (i.e., the two points where pressure is applied) between the elastic piece and the temple are located between the contact points of the support bracket and the nose bridge and the temple. The five-point staggered arrangement of the three-point support of the support bracket and the two-point pressure of the elastic piece can make the force on the multiple contact points between the frame glasses and the support bracket uniform, achieving force balance.

[0055] Preferably, the nose bridge is provided with a first recess for accommodating the nose bridge of the frame glasses and limiting the movement of the frame glasses in the Y direction (i.e., the direction of the center line of symmetry of the frame glasses).

[0056] Preferably, the temple support is provided with a second recess and a third recess for supporting one temple of the frame glasses in the open state, respectively, and limiting the movement of the frame glasses in the X direction (i.e., the direction of the line connecting the two contact points of the temple support and the temple of the frame glasses).

[0057] Preferably, the second recess and the third recess are arc-shaped recesses with the distal end downward, so as to limit the inward folding or deformation of the temple.

[0058] Preferably, the nose bridge and the temple support are connected in a T shape or a cross shape. The temple support can be in the form of a straight rod, a V-shaped rod, a wave-shaped rod, or an arc-shaped rod.

[0059] The supporting bracket is made of high-strength rust-resistant hard material, such as stainless steel, aluminum, or other high-strength alloy materials or hard plastic materials. The parts of the bridge and the temple supports that contact the frame glasses are made of flexible materials, such as plastic, rubber, etc., to increase the friction between the glasses and the supporting bracket and prevent scratches on the glasses. Preferably, a flexible material layer is laid on the surface of the first concave part of the bridge and the second and third concave parts of the temple supports to increase the friction between the concave parts and the frame glasses, enhance the fixing effect, and prevent the temple or bridge of the frame glasses from being pressed and leaving marks, thereby protecting the frame glasses.

[0060] The elastic member is made of elastic material, such as spring sheet, rubber spring, spring rod, silicone rod, or elastic hose, etc. After elastic deformation, the elastic member provides a downward elastic force through elastic recovery force to prevent the frame glasses from moving, rotating, and being damaged.

[0061] The elastic member can be one, for example, as shown in FIG. 1, the middle part of the elastic member is fixed with the rotating arm, and when the elastic member rotates with the rotating arm to the second position, the outer side of the elastic member can press against the two temple of the frame glasses on the supporting bracket. The elastic member can also be two or more, for example, as shown in FIG. 2, two elastic members press against the temples respectively. Figure 1 Figure 4

[0062] The shape of the elastic member can be straight or curved, as shown in FIGS. 3 and 4. Figure 1 Figure 4 Preferably, the supporting bracket is arranged in a glasses cleaning device to support the frame glasses during cleaning. The glasses cleaning device includes a frame glasses fixing structure and a fixing table. The fixing table is located above the frame glasses fixing structure to fix the frame glasses fixing structure in the glasses cleaning device. The driving unit of the frame glasses fixing structure is arranged above the fixing table, and the connecting member connects the fixing table and the supporting bracket.

[0063] As shown in FIGS. 5 and 6, the working process of the frame glasses fixing structure of the present embodiment is as follows:

[0064] As shown in FIGS. 5 and 6, the working process of the frame glasses fixing structure of the present embodiment is as follows: Figure 1 Figure 3

[0065] ​​​​​When the frame glasses to be cleaned are fixed, the frame glasses are placed on the supporting bracket, the nose bridge of the frame glasses is positioned in the first recess of the nose bridge support, and the two legs of the frame glasses are positioned in the second recess and the third recess of the leg support, respectively. The driving unit drives the worm to rotate the worm gear, and the worm gear drives the rotating pressing piece to rotate from the first position to the second position, so that the elastic piece of the rotating pressing piece presses against the leg of the frame glasses until the frame glasses are pressed tightly, realizing quick and flexible fixing of the frame glasses, avoiding wear of the frame glasses during cleaning, reducing the manual operation process, and improving the convenience and comfort of automatic cleaning of the glasses.

[0066] After cleaning, when the frame glasses are taken out, the driving unit drives the worm to rotate the worm gear, the worm gear drives the rotating pressing piece to rotate from the second position to the first position, the rotating pressing piece leaves the leg of the frame glasses, and the frame glasses can be quickly taken out from the supporting bracket.

[0067] Embodiment 2:

[0068] Another embodiment of the present application is a frame glasses fixing structure, which is different from embodiment 1 in that, as shown in Figure 4 When the elastic piece presses against the leg on the leg support, an outward and downward force is generated on the leg, and the inward folding deformation of the leg is limited. Preferably, protrusions are arranged on both sides of the contact point between the leg support and the frame glasses, so as to limit the movement of the frame glasses in the X direction.

[0069] Preferably, as shown in Figure 4 The two elastic pieces are respectively connected to the two same-direction output shafts of the driving unit, and rotate synchronously. The rotation of the two output shafts of the driving unit enables the elastic pieces on both sides of the nose bridge support to press against the two legs of the frame glasses respectively, so as to achieve the effect that the frame glasses are stably kept on the supporting bracket.

[0070] Preferably, the elastic piece has an arc or zigzag shape, so that the elastic pieces on both sides of the nose bridge support can press against the two legs of the frame glasses more stably.

[0071] The frame glasses fixing structure and the glasses cleaning device of the present application enable the frame glasses to be placed flat on the supporting bracket in an open state, the nose bridge is placed on the nose bridge support of the supporting bracket, and the two legs are placed on the leg supports below the elastic pieces. The elastic piece of the rotating pressing piece is rotated by the driving unit through the transmission unit. When the elastic piece rotates to the first position, the frame glasses can be quickly taken out or placed. When the elastic piece rotates to the second position, the leg is pushed and pressed from top to bottom, the frame glasses are quickly and flexibly fixed, wear of the frame glasses during cleaning is avoided, the manual operation process is reduced, and the convenience and comfort of automatic cleaning of the glasses are improved.

[0072] The present invention's frame eyeglass fixing structure and eyeglass cleaning device utilizes three-point support and two-point elastic compression, preventing damage to the glasses caused by sudden torque changes during single-point fixation. The two-point elastic compression ensures uniform force distribution across multiple contact points. In particular, the use of multiple (e.g., three) staggered recesses further stabilizes the glasses, ensuring they remain stable despite external forces during rinsing and drying.

[0073] The frame glasses fixing structure and glasses cleaning device of the present invention use a connecting piece to connect the driving unit placed outside the humid environment with the supporting bracket and the rotating pressure piece placed in the humid environment, and the transmission unit is placed inside the connecting piece, which can prevent electronic components such as the driving unit from being affected by the humid environment during glasses cleaning, thereby improving operational safety and the service life of the device.

[0074] Although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. Any equivalent changes or modifications made without departing from the spirit and scope of the present invention are also within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the content defined in the claims of this application.
