Description

Technical Field

[0001] The product involved in this utility model belongs to a cleaning product, and in particular a glass wiper with a movable rubber strip cover and an asymmetrical distribution of the rubber strip and the rod. Background Technology

[0002] Glass cleaning products are already mature products, offering both wiping and scraping functions. This invention only relates to the scraping function. Current glass wipers include a handle and a scraper head. The scraper head comprises a rubber strip, a rubber strip cover, and a base. The rubber strip is a thin, elongated rubber material, approximately 30 cm in length. The rubber strip cover is cut from an aluminum profile and is about 1 cm shorter than the rubber strip. The rubber strip cover keeps the rubber strip in a straight working position. There is a cooperating structure between the rubber strip and the rubber strip cover to prevent the rubber strip from detaching from the horizontal opening of the rubber strip cover. The front part of the rubber strip scrapes away dirt from the glass surface, while the rear part of the rubber strip is fixed inside the rubber strip cover. The rubber strip sheath is fixed in a groove in the base, which is made of plastic. There are various ways to fix the rubber strip sheath to the groove. For example, the groove and the rubber strip sheath may have the same cross-sectional shape, but the groove may be slightly smaller. The base may be boiled in hot water, and the rubber strip sheath and rubber strip may be inserted while the base is heated. Alternatively, the rubber strip sheath and rubber strip can be mechanically pressed in, securing them within the groove. Another method is to use a groove sized to facilitate insertion, with the rubber strip sheath partially deforming within the groove to increase its size, thus securing it. In some products, the rubber strip sheath can move within the groove under pressure, but this requires considerable force, which is not the normal operating condition for the product. Other fixing methods include adhesive bonding and screw fixing. The base is connected to the end of the rod, which can be a straight rod, an arc rod, or a U-shaped rod. The rubber strips are symmetrically distributed with respect to the rod, and the rubber strip sleeves and the base cannot move relative to each other.

[0003] Existing glass scraping products work well when scraping exterior windows of high-rise buildings. When the rod is horizontal and the rubber strip is perpendicular to the rod, it's easy to apply force and clean the glass surface. However, to scrape corners of high or low surfaces, the rod needs to be tilted at a certain angle to the ground, and the rubber strip needs to be rotated to a position perpendicular or horizontal to the ground. In these situations, it's inconvenient to apply force, making it difficult to clean the glass surface thoroughly.

[0004] Assuming a person cleaning windows is 170 cm tall, the handhold height of the cleaning rod at a high position is approximately 210 cm. The average building height is 275 cm. Subtracting the building structure and window frames, the height of the exterior window glass is approximately 260 cm. 260 cm - 210 cm = 50 cm. At the top of the product, the dimension of the symmetrical plane between the rubber strip and the rod is 50 cm. This allows the person to scrape the higher parts of the exterior window glass when the rod is horizontal and the rubber strip is vertical. Similarly, for a person 170 cm tall, the handhold height of the cleaning rod at a low position is approximately 75 cm, and the lower part of the exterior window glass is approximately 15 cm. 75 cm - 15 cm = 60 cm. If the person then squats down by about 10 cm, the dimension of the symmetrical plane between the rubber strip and the rod at the bottom of the product is also 50 cm. This allows the person to scrape the lower parts of the exterior window glass when the rod is horizontal and the rubber strip is vertical. For existing window cleaning products, the rubber strip needs to be 50 cm on both sides of the rod, meaning the strip length would need to be 100 cm, which is too long.

[0005] The core idea of ​​this invention is that the rubber strip sleeve can move within the groove of the base and can be locked in its movable position. If the base width is 9 cm, then 50 + 9 / 2 = 54.5 cm, and the rubber strip length of approximately 55 cm, can meet the requirement of 50 cm on each side. With the rod horizontal and the rubber strip perpendicular to the rod, theoretically, it can scrape both high and low surfaces of high-rise windows, thus improving the adaptability of the window cleaner. In practical use, various glass sizes exist, and the rubber strip, approximately 55 cm or longer, may be wider than the glass size. In such cases, two sizes of scraper heads can be used, for example, with rubber strips of 35 cm and 65 cm in length, further improving the adaptability of the glass cleaning product. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a glass cleaning product in which the rubber strip sleeve can move in the groove of the base and be locked when cleaning the exterior glass of high-rise buildings. Using this product, a larger area of ​​the glass surface outside the window can be scraped when the rod is horizontal and the rubber strip is vertical.

[0007] To solve the above-mentioned technical problems, the contents of this utility model are as follows:

[0008] A glass wiper includes a rod and a wiper head. The wiper head includes a rubber strip, a rubber strip sheath, and a base. The rubber strip is fixed inside the rubber strip sheath, which is located within a groove in the base. The base is connected to the end of the rod. The groove has a structure to prevent the rubber strip sheath from detaching from the opening of its cross-section, allowing the rubber strip sheath to move within the groove. The base also has a cantilever beam. When the rubber strip sheath is not inserted, a portion of the front end of the cantilever beam naturally intrudes into the space of the groove. The cantilever beam also has a handle. Inserting the rubber strip sheath causes elastic deformation of the cantilever beam, generating a spring force that presses the rubber strip sheath against the groove, locking the rubber strip sheath in place. Lifting the handle forcefully disengages the cantilever beam from the outer surface of the rubber strip sheath, relieving pressure on the rubber strip sheath, allowing it to move within the groove.

[0009] Furthermore, a limiting block is fixed on each of the rubber strip sleeves on both sides of the base, and the limiting blocks will not move into the groove.

[0010] Furthermore, the limiting block is located in an area less than 12 mm from the end face of the rubber strip in both directions.

[0011] By implementing this utility model, when using this product to scrape the exterior glass of high-rise buildings, lifting the handle upwards forcefully raises the end of the cantilever beam, releasing the elastic force applied to the rubber strip sleeve. The rubber strip sleeve can then move within the groove. Releasing the handle locks the rubber strip sleeve in place. This allows for easy scraping of a larger area of ​​the glass surface outside the window when the rod is horizontal and the rubber strip is vertical. Furthermore, the rubber strip sleeve can have a limiting block to prevent it from moving out of the groove, improving product safety and significantly enhancing its effectiveness. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] Figure 1 This is a structural schematic diagram of an embodiment of the present invention.

[0014] Figure 2 This is a structural schematic diagram from another angle of this embodiment. Detailed Implementation

[0015] like Figure 1 and Figure 2As shown, a glass wiper includes a rod (1) and a scraper head. The scraper head includes a rubber strip (21), a rubber strip sleeve (22), and a base (23). The front part of the rubber strip (21) scrapes away dirt from the glass surface, and the rear part of the rubber strip (21) is fixed inside the rubber strip sleeve (22). The base (23) is connected to the end of the rod (1). Figure 1 and Figure 1 As shown, the rear part of the adhesive strip sleeve (22) is circular, and the groove is also circular with an opening. The groove has a small opening and a large inner opening, which can prevent the adhesive strip sleeve (22) from detaching from the opening direction of the cross section of the groove. The adhesive strip sleeve (22) and the groove are in sliding fit, and the adhesive strip sleeve (22) can move easily in the groove.

[0016] like Figure 1 and Figure 2 As shown, there is a through hole in the middle of the base (23), and there are grooves on both sides of the through hole. The solid part in the middle of the through hole is a cantilever beam. When the rubber strip sleeve (22) is not installed, in its natural state, a part of the front end of the cantilever beam invades the space of the groove. There is also a handle (A) at the end of the cantilever beam. After the rubber strip sleeve (22) is installed, the cantilever beam undergoes elastic deformation, and the resulting elastic force presses the rubber strip sleeve (22) tightly, so that the rubber strip sleeve (22) presses the grooves on both sides of the hole, and the rubber strip sleeve (22) is locked. When the handle (A) is lifted, the cantilever beam is separated from the outer surface of the rubber strip sleeve (22), and the cantilever beam releases the pressing force on the rubber strip sleeve (22). The rubber strip sleeve (22) and the rubber strip (21) can move easily in the groove together.

[0017] like Figure 1 and Figure 2 As shown, a limiting block (221) is fixed to each of the rubber strip sleeves (22) on both sides of the base (23) with countersunk screws (222). The limiting blocks (221) have a uniform wall thickness of 2.2 mm. The 2.2 mm wall thickness covers the outer surface of the rubber strip sleeve (22), so it will not move into the groove. Figure 1 As shown, the limiting block (221) covers the end face and 5 mm long outer surface of the rubber strip sheath (22). Therefore, the limiting block (221) is 2.2 mm and 5 mm away from the end face of the rubber strip sheath (22) in two directions, which are both less than 12 mm.

[0018] It should be noted that the above description and specific embodiments only illustrate one representative structural solution and do not provide a comprehensive description. Therefore, they should not be construed as limiting the scope of protection of this utility model. The scope of protection of this utility model is determined by the appended claims.
