Description

Technical Field

[0001] This utility model relates to a glass wiper, and more particularly to an anti-fall-off magnetic glass wiper outer body. Background Technology

[0002] Existing magnetic glass cleaners include a pair of magnetic erasers, each containing a magnet, which is controlled by a pressure cap on the back of the erasers. Wiping strips and wiping felt are located at opposite ends of the erasers. This type of glass cleaner has the following problems during use:

[0003] 1. When in use, it is held in place by the attraction of the two magnetic erasers on the inside and outside of the glass window. When you are done wiping, you need to hold the two magnetic erasers with both hands. Otherwise, the magnetic eraser on the outside of the glass window will easily fall off after losing the attraction of the magnetic eraser on the inside.

[0004] 2. The glass cleaner uses sliding friction with the glass surface, which is difficult to operate. When wiping, the glass cleaner located on the outside is prone to jumping. If you are not careful, it may even fall downstairs, which can not only easily break the glass cleaner, but also easily injure people.

[0005] To address the aforementioned issues, CN108272381A discloses a labor-saving, anti-fall-off double-sided glass cleaner, comprising an inner cleaner body and an outer cleaner body. The inner cavities of both the inner and outer cleaner bodies are equipped with mutually attracting magnets. The front surfaces of both the inner and outer cleaner bodies are respectively equipped with a rubber scraper and a wiping felt strip. A vacuum suction cup is located on the front surface of the outer cleaner body. A friction protrusion is located at the center of the vacuum suction cup, and a friction ring or multiple small protrusions evenly distributed around its circumference are located within the inner cavity of the vacuum suction cup. The friction protrusion, friction ring, or small protrusions are all made of a hard material. During use, the vacuum suction cup deforms under the magnetic force of the magnets, causing the friction protrusion, friction ring, or small protrusions to contact the outer side of the window glass, thus preventing the suction force of the suction cup from hindering the wiping movement of the outer cleaner body. When the outer cleaner body detaches from the magnets of the inner cleaner body, it adheres to the outer side of the window glass under the action of the vacuum suction cup, preventing the outer cleaner body from accidentally falling off during or after wiping.

[0006] This type of glass cleaner has the following problems:

[0007] 1. Because the friction ring or small protrusions on its outer friction body are made of a hard material with a low coefficient of friction and are located on the inner wall of the vacuum suction cup, they are not easy to process and manufacture. Even if they are fixed by heat sealing or bonding, they are not firm and are easy to fall off, resulting in a short service life.

[0008] 2. Because the friction ring or small protrusion protrudes from the inner conical surface of the suction cup and has a certain height, it can easily affect the suction force of the suction cup, causing the outer friction body to fall off. Utility Model Content

[0009] The technical problem to be solved by this utility model is to provide an easy-to-process, easy-to-wipe magnetic glass wiper body that prevents it from falling off, which can avoid the suction force of the suction cup from hindering the wiping movement of the wiper body and is reliable in operation.

[0010] To solve the above problems, the present invention adopts the following technical solution:

[0011] A magnetic glass cleaner with anti-fall-off function includes a box body consisting of an outer cleaning plate and a rear cover. A magnet is provided on a sliding plate inside the box body. A wiping strip and a wiping felt are provided in front of the outer cleaning plate. Two pairs of guide posts are symmetrically arranged on the outer cleaning plate within the box body. The sliding plate is slidably mounted on the guide posts. A suction cup is located at the center of the sliding plate. The key feature is that an isolation plate is provided inside the suction cup. The isolation plate is inserted into the central hole of the suction cup via a positioning sleeve fixed at the center. The isolation plate is circular and petal-shaped, with multiple elastic teeth evenly distributed around its outer circumference. These teeth deform under the action of the magnet during wiping, supporting the edge of the suction cup and contacting the outside of the window glass.

[0012] As a further preferred embodiment, the positioning sleeve is fixed to the center of the back of the isolation plate by rivets.

[0013] As a further preferred option, a reset plate is fixed to the upper end of each pair of guide posts for automatic reset of the sliding plate after disengagement from the inner rubbing body.

[0014] As a further preferred embodiment, a conical protrusion is provided behind the sliding plate, and colored beads are provided at the upper end of the protrusion; a hemispherical transparent cover is provided on the back cover at the corresponding protrusion position, and the colored beads are inserted into the transparent cover when the magnet is reset; when the magnet drives the sliding plate to stick to the inner side of the outer rubbing plate under the adsorption of the inner rubbing body, the colored beads leave the transparent cover.

[0015] Preferably, the guide post and the outer wiping plate are an integral structure.

[0016] Preferably, a metal plate is fixed behind the sliding plate, and the magnet passes through the sliding plate and is attracted to the metal plate to facilitate the repositioning of the magnet.

[0017] Preferably, the magnets are four pieces symmetrically arranged on both sides of the suction cup, and rectangular grooves and circular through holes are respectively provided on the outer cleaning plate corresponding to the positions of the magnets and the suction cup. The magnets and the suction cup are respectively inserted into the corresponding rectangular grooves and circular through holes.

[0018] Preferably, a slider is installed on the upper inner side of the outer wiping plate via a slide rail, and a metal sheet is connected to the slider. The lower end of the metal sheet passes through the outer wiping plate and can protrude through the upper edge of the circular through hole for inserting a suction cup to release its suction force. A reset spring is provided between the slider and the outer wiping plate on both sides, and a rectangular groove is provided on the upper end of the back cover corresponding to the slider to facilitate the sliding of the slider.

[0019] Preferably, a self-lubricating coating is provided on the inside of the isolation plate to avoid scratching the window glass.

[0020] The beneficial effects of this utility model are:

[0021] 1. Because an isolation plate is provided inside the suction cup, the isolation plate is inserted into the central hole of the suction cup through a positioning sleeve fixed at the center. The isolation plate is circular and petal-shaped, with multiple elastic teeth evenly distributed around its outer circumference. During wiping, the elastic teeth are deformed by the action of the magnet, which can lift the edge of the suction cup, so that the suction cup is completely separated from the window glass and the isolation plate contacts the outside of the window glass. This can avoid the suction force of the suction cup from hindering the wiping movement of the outer wiping body, thereby avoiding the sliding resistance formed by the suction cup on the outer wiping body. This greatly reduces the frictional resistance between the outer wiping body and the outside of the window glass, making the wiping work easy and free. Moreover, the isolation plate can be formed by stamping and inserted into the central hole of the suction cup by a rivet at the center, which is easy to process and manufacture and not easy to fall off.

[0022] 2. After wiping is complete and the outer cleaning body is removed from the suction cup, the elastic toothed plate will reset and help the edge of the suction cup to contact and adhere to the outside of the window glass, thus preventing the outer cleaning body from falling off. The operation is reliable.

[0023] 3. Two pairs of guide posts are symmetrically arranged inside the box on the outer cleaning plate, and a sliding plate is slidably installed on the guide posts. A suction cup is located at the center of the sliding plate. A reset iron plate is fixed at the upper end of each pair of guide posts for automatic reset of the sliding plate after detachment from the inner cleaning body. The automatic reset of the sliding plate pulls the center part of the suction cup outward, thereby increasing the suction force of the suction cup. This allows the outer cleaning body to be stably attached to the outside of the glass after detachment from the inner cleaning body, effectively preventing the outer cleaning body from falling and damaging or injuring others, thus improving safety.

Detailed Implementation

[0032] like Figures 1-5 As shown, this utility model relates to an anti-falling magnetic glass cleaner, comprising a box body formed by connecting an outer cleaning plate 1 and a rear cover 7 with screws. A magnet 4 is provided inside the box body. Two pairs of guide posts 101, integrally formed with the outer cleaning plate 1, are symmetrically arranged on the outer cleaning plate 1 within the box body. A sliding plate 12, which can slide up and down along the guide posts 101, is slidably mounted on the two pairs of guide posts 101. A transparent plastic suction cup 5 is fitted into the central hole at the front of the sliding plate 12. An isolation plate 6 is provided inside the suction cup. A positioning sleeve 17 is fixed to the center of the back of the isolation plate 6 by rivets and inserted into the central hole of the suction cup 5. The isolation plate 6 is a circular petal-shaped piece stamped from a thin steel sheet. Multiple elastic teeth 601 are evenly distributed around the outer circumference of the isolation plate 6. During wiping, these teeth deform under the action of the magnet 4, supporting the edge of the suction cup 5 and contacting the outer surface of the window glass. A self-lubricating coating made of a self-lubricating material is applied to the inner side of the isolation plate 6 to prevent scratching the window glass.

[0033] A metal plate 14 is fixedly attached to the back of the sliding plate 12. The magnet 4 passes through the sliding plate 12 and is attracted to the metal plate 14 to facilitate the installation of the magnet 4 and the resetting of the sliding plate 12.

[0034] The magnets 4 are four pieces and are symmetrically arranged on both sides of the suction cup 5. On the outer wiping plate 1, there are rectangular grooves 102 and circular through holes 103 respectively corresponding to the positions of the magnets 4 and the suction cup 5. The magnets 4 and the suction cup 5 are respectively inserted into the corresponding rectangular grooves 102 and circular through holes 103 through clearance fit.

[0035] A reset plate 13 is fixed between the upper ends of each pair of guide posts 101 by screws, which is used for the automatic reset of the sliding plate 12 after it is disengaged from the inner rubbing body.

[0036] A conical protrusion 15 is provided behind the sliding plate 12, and a colored bead 16 is fixed at the upper end of the protrusion 15. The colored bead 16 is preferably made of plastic rhinestone. A hemispherical transparent cover 8 is provided on the rear cover 7 corresponding to the protrusion. When the magnet 4 is reset, the colored bead 16 is inserted into the transparent cover 8. When the magnet 4 is attracted by the inner wiper and drives the sliding plate to stick to the inner side of the outer wiper 1, the colored bead 16 slides with the sliding plate and leaves the transparent cover 8. By observing whether the colored bead 16 is located inside the transparent cover 8, the current position of the magnet 4 can be directly determined. This allows for the detection of whether the glass wiper suction meets the thickness requirements of the glass to be wiped, ensuring that the suction is appropriate and preventing the outer wiper from falling off.

[0037] A slider 9 is installed on the upper inner side of the outer cleaning plate 1 via a slide rail. A metal piece 10 is connected to the slider 9. The lower end of the metal piece 10 is inserted obliquely into the outer cleaning plate 1 and can pass through the upper edge of the circular through hole 103 for inserting the suction cup 5 to release its suction force. Reset springs 11 are symmetrically provided on both sides of the slider 9 and between the outer cleaning plate 1. A rectangular groove 701 is provided on the upper end of the rear cover 7 corresponding to the slider 9 to facilitate the sliding of the slider 9, thereby releasing the suction cup 5.

[0038] A wiping felt strip 2 is glued to the front of the outer wiping plate 1; a groove is provided on one side of the front of the outer wiping plate 1 to hold a rubber scraper 3. Two through holes 21 are provided at the lower part of the rear cover 7 for connecting a safety rope.

[0039] In use, hold the outer wiper body with one hand and place it against the outside of the glass window, while holding the inner wiper body with the other hand and placing it against the inside of the glass window. Adjust the magnetic adjustment component on the inner wiper body. When the magnet 4 is attracted by the magnetic force and moves the sliding plate against the inside of the outer wiper plate 1, the elastic teeth 601 of the isolation plate 6 deform under the action of the magnet 4, which can support the edge of the suction cup and make the isolation plate 6 contact the outside of the window glass. Figure 6 As shown, this greatly reduces the sliding resistance formed by the suction cup 5 on the outer wiper, and avoids the suction force of the suction cup from hindering the wiping movement of the outer wiper during wiping; at the same time, the colored beads 16 slide along with the sliding plate 12 and leave the transparent cover 8. The user can know whether the outer wiper is adsorbed on the outside of the glass window by observing the transparent cover 8, and can release the outer wiper and move the inner wiper to drive the outer wiper to wipe simultaneously.

[0040] After wiping is complete, remove the inner cleaning body. The magnet 4 on the sliding plate loses its attraction to the inner cleaning body. Under the attraction of the magnet 4, the sliding plate 12 and the metal plate 14 quickly move backward and reposition onto the repositioning iron plate 13, pulling the center of the suction cup 5 outward. At the same time, the isolation piece 6 repositions and adheres to the inner wall of the suction cup, allowing the edge of the suction cup 5 to quickly contact and adhere to the outer side of the window glass. Figure 7 As shown, the external wiping body can be stably adsorbed onto the outside of the glass under the action of the suction cup 5, effectively preventing the external wiping body from falling off.

[0041] Then hold the outer cleaning body, hook the slider 9 with one finger and slide it into the box, so that the lower end of the metal piece 10 is inserted into the suction cup 5, and the suction force of the suction cup 5 can be released, and the outer cleaning body can be removed.

[0042] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
