Description

Technical Field

[0001] The utility model relates to the field of civil aviation, in particular to a glue scraping tool for a slide rail on an airplane cabin floor. Background Art

[0002] Currently, domestic civil aircraft maintenance companies, when conducting scheduled inspections, passenger-to-cargo conversions, and aircraft return operations in hangars, need to remove and install cabin equipment and facilities, including cabin floors, seats, galleys, lavatories, partitions, lockers, and emergency cabinets, for testing, inspection, and repair. These facilities are mounted on slide rails for securement, and this removal and installation involves scraping and sealing glue. Sealing glue prevents liquid leakage, maintains airtightness, counteracts vibration, and provides sound and heat insulation. Since residual glue remains on the outer surface of the slide rails after removal, it must be scraped before installation to improve the quality of the subsequent sealing.

[0003] On all types of existing civil airliners, the remaining glue on the outer surface of the slide rail is scraped off little by little with a glue scraper. The construction efficiency is slow, the squatting working posture is prone to fatigue, and long-term construction can easily cause physical discomfort to workers, posing a safety hazard.

[0004] In actual work, the residual glue is unevenly deformed and randomly attached to the outer surface of the slide rail. Visual inspection is time-consuming and prone to omissions in finding the residual glue, while the traditional glue scraper has a small scraping area and low efficiency. Utility Model Content

[0005] The utility model aims to provide a tool for scraping glue from a slide rail on an aircraft cabin floor, which is used to improve the efficiency of scraping glue from the slide rail.

[0006] The purpose of the utility model can be achieved through the following technical solutions.

[0007] A tool for scraping glue from a slide rail on an aircraft cabin floor, wherein the outer shape of each side of the main body of the slide rail is configured as a continuous upper surface consisting of at least a first surface, a second surface, and a third surface. The tool comprises a special-shaped blade and a handle, wherein the special-shaped blade is detachably connected to the handle, and the special-shaped blade is configured as an integral structure consisting of a first blade, a second blade, and a third blade, wherein the bottom surface of the first blade of the first blade is configured to be shaped to match and fit with the first surface, the side surface of the second blade of the second blade is configured to be shaped to match and fit with the second surface, and the third blade of the third blade is configured to be shaped to match and fit with the third surface. The bottom surface is constructed into a shape that can match and fit with the third surface; the bottom surface of the first blade body, the side surface of the second blade body and the bottom surface of the third blade body are connected to form a blade support surface that matches and fits with the continuous upper surface shape on the slide rail; the front end of the first blade body is provided with a first blade bevel that forms the blade edge of the first blade body together with the bottom surface of the first blade body; the front end of the second blade body is provided with a second blade bevel that forms the blade edge of the second blade body together with the side surface of the second blade body; and the front end of the third blade body is provided with a third blade bevel that forms the blade edge of the third blade body together with the bottom surface of the third blade body.

[0008] The special-shaped cutter body of the utility model can simultaneously realize the scraping work of the first surface, the second surface and the third surface of the slide rail. Pushing the handle makes the special-shaped cutter body move on the continuous upper surface outside the slide rail to scrape the glue, which can improve the scraping efficiency.

[0009] The utility model also has the following preferred designs:

[0010] The first blade body inclined surface, the second blade body inclined surface and the third blade body inclined surface of the utility model are sequentially connected to form a continuous folded surface through their respective boundary fits, so that the blades of the first blade body, the second blade body and the third blade body are connected to form a folded line, thereby improving the cutting ability of the special-shaped blade body when scraping rubber.

[0011] The rear surface of the first blade of the first blade of the utility model is connected to the bottom surface of the second blade of the second blade to form a lower groove of the special-shaped blade, which can reduce the contact area between the first blade and the first surface of the slide rail, and reduce the contact area between the second blade and the second surface of the slide rail, thereby reducing the friction when scraping glue.

[0012] The rear ends of the second and third blade bodies of the present invention are provided with an inclined handle mounting surface, each having a threaded hole. The lower ends of the handles are provided with an externally threaded surface that matches the threaded hole, and the externally threaded surface is threadedly connected to the threaded hole, thereby facilitating the installation and removal of the special-shaped blade bodies and handles.

[0013] The utility model defines the width of the slide rail as the X-axis, the length of the slide rail as the Y-axis, and the height of the slide rail as the Z-axis. When the special-shaped blade is attached to the slide rail for scraping glue, the center axis of the handle forms a 45° angle with the X-axis-Y-axis plane, and the center axis of the handle forms a 15° angle with the Y-axis-Z-axis plane. This allows for more efficient force distribution when scraping glue, making scraping easier.

[0014] The special-shaped cutter body of the utility model is provided with an illumination lamp, which provides illumination to the glue removal area and facilitates the inspection of the glue removal effect.

[0015] Preferably, the lighting lamp is arranged on the third blade inclined surface of the third blade.

[0018] 1. The utility model provides a tool for scraping glue from slide rails on aircraft cabin floors. The tool can scrape glue from the first, second, and third surfaces of the slide rails simultaneously. Pushing the handle causes the special-shaped blade to move along the continuous upper surface outside the slide rails to scrape glue. This improves scraping efficiency, reduces labor intensity, and reduces glue removal maintenance costs.

[0019] 2. The blades of the first blade body, the second blade body and the third blade body of the utility model are connected into a broken line, which improves the cutting ability of the special-shaped blade body when scraping glue.

[0020] 3. The present invention can reduce the contact area between the first cutter body and the first surface of the slide rail, and reduce the contact area between the second cutter body and the second surface of the slide rail, thereby reducing the friction when scraping glue.

[0021] 4. The utility model sets a scientific and reasonable installation angle of the handle center axis according to the shape of the slide rail, so that the force distribution when scraping glue is more reasonable and the scraping glue is easier.

[0022] 5. The special-shaped blade body and handle of the utility model are easy to install and disassemble.

[0023] 6. The utility model is also provided with an illumination lamp, which can be used to conveniently check the glue removal effect when scraping glue. BRIEF DESCRIPTION OF THE DRAWINGS
