[0002] A cleaning scraper is a tool used for cleaning work, consisting of a blade and a handle. The blade is usually made of stainless steel or carbon steel and has a sharp edge, which can effectively scrape off dirt, stains, glue and paint from various surfaces. The handle is usually made of plastic, rubber or wood, mainly for easy gripping and operation, so that the user can better control the force and angle of the scraper.

[0003] A search revealed Chinese Patent Publication No. CN108104037A, which discloses a cleaning scraper, including a scraper blade, a handle, a hand guard, an extension rod, and a hammer. The extension rod is located at the head of the scraper blade and connected to the handle. The hand guard is located on the handle, with a matching Velcro strip between the bottom of the hand guard and the handle. The hammer is located at the head of the scraper blade. This invention provides warmth to the user's hands in cold weather; the protective cover prevents the scraper blade from accidentally injuring others or oneself when not in use, ensuring personal safety; and it also functions as a nail remover and hammer. This invention is simple, practical, and multifunctional. In contrast, existing elevator door guide rail cleaning scrapers have the scraper blade and handle fixed together. This fixing method cannot be adjusted when encountering elevator door guide rails of different sizes, and it is inconvenient to replace either the scraper blade or the handle if either is damaged. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an elevator door guide rail cleaning scraper, which aims to improve the problem that the existing fixing method cannot be adjusted when encountering elevator door guide rails of different sizes, and is not convenient to replace when either the scraper or the handle is damaged.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an elevator door guide rail cleaning scraper, including a handle, a rotating handle rotatably connected to the top of the handle, a take-up reel fixedly connected to the bottom of the rotating handle, a steel wire fixedly connected to the left side of the take-up reel, a fixing buckle fixedly connected to the end of each steel wire, a spring fixedly connected to the top of the fixing buckle, a fixing plate slidably connected to the left side of the handle, and an angle adjustment mechanism installed on the left side of the fixing plate, the angle adjustment mechanism being used to adjust the angle of the elevator door guide rail cleaning scraper.

[0006] With the above technical solution: when the handle rotates, the take-up reel fixed below it will also rotate synchronously. When the take-up reel rotates, it will drive the wire to rewind. The rewinding of the wire will pull the fixing buckle upward, so that the fixing plate can be pulled out to replace the blade. Then, the new fixing plate is inserted back into its original position. Then, the handle is released. At this time, the spring fixed above the fixing buckle will push the fixing buckle back into its original position, so that it can be reinserted into the hole on the fixing plate for fixing.

[0013] As a further description of the above technical solution:

[0014] Rubber pads are fixedly connected to both sides of the fixing rod, and anti-slip textures are formed on the outer walls of both rubber pads.

[0015] The above technical solution improves the friction of the fixing rod by creating anti-slip textures on the rubber pad.

[0016] As a further description of the above technical solution:

[0017] The upper and lower ends of the connecting rod are threaded with limit plates, and the outer walls of the two limit plates are threaded with screws.

[0018] The above technical solution uses screws to fix the limiting plate, which can prevent the connecting rod from falling off.

[0019] As a further description of the above technical solution:

[0020] A fixing groove is provided on the left side of the shovel blade, and a protective shell is slidably connected to the inner side of the fixing groove.

[0021] The above technical solution provides protection for the shovel blade by fixing it with a fixing groove.

[0022] As a further description of the above technical solution:

[0023] Anti-slip sleeves are installed at equal intervals on the outer wall of the handle, and the left and right ends of the multiple anti-slip sleeves are fixedly connected with Velcro.

[0024] The above technical solution uses a non-slip sleeve secured with Velcro to improve the grip of the handle.

[0025] As a further description of the above technical solution:

[0026] Limiting plates are installed at both the upper and lower ends of the adjusting rod, and thumbtacks are fixedly connected to the left side of both limiting plates.

[0027] The above technical solution allows the limiting plate, which is fixed by a thumbtack, to restrict the range of motion of the shovel handle.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the rotating handle pulls the fixing buckle through the winding reel and steel wire to replace the fixing plate, and then inserts the new fixing plate back into the original position. At this time, the spring pushes the fixing buckle back into the original position, thereby realizing the effect of quickly replacing the blade of the elevator door guide rail cleaning scraper when encountering elevator door guide rails of different sizes, and also facilitating later replacement and maintenance.

[0030] 2. In this utility model, the nut is rotated to remove it, and then the fixing rod is pulled out. Then, with the cooperation of the connecting rod, the angle of the shovel is adjusted. Then, the fixing rod is reinserted into the hole where the shovel and the adjusting rod are aligned. Then, the nut is rotated back under the fixing rod to prevent the nut from falling off, thereby achieving the effect of adjusting the angle of the cleaning shovel for the elevator door guide rail.
