Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft repair technology, and in particular to a weather sealing tool for aircraft windshields. Background Technology
[0002] Aircraft windshields, whether on the ground, in flight, or about to land, are used by pilots to observe taxiways and runways, ensuring smooth takeoff, flight, and landing. As a crucial structural component of an aircraft, the windshield must withstand enormous pressure and aerodynamic loads while maintaining good light transmission; therefore, its weather sealing and moisture-proof performance is particularly important.
[0003] Weather sealing of the windshield refers to ensuring a reliable seal between the windshield and the aircraft fuselage using specific sealing materials and techniques. This prevents moisture, rainwater, or condensation from entering the windshield's mounting frame, thus avoiding potential electrical faults or structural problems. A malfunctioning windshield during operation directly threatens flight safety. To enhance the windshield's sealing and impact resistance, an outer frame is often used to connect the windshield to the aircraft fuselage. Both the outer frame and the windshield typically protrude slightly from the aircraft's outer surface. Therefore, weather sealing involves applying a sealant between the windshield and the outer frame edge, ensuring even application and proper curing.
[0004] In existing technologies, applying sealing adhesive typically requires a positioning plate of a certain length. The size of the positioning plate is usually determined based on the shape and dimensions of the windshield. The plate is then fixed to the windshield surface, ensuring one side of the scraper is in contact with it. The adhesive is applied by moving the scraper, maintaining constant contact with the plate, to achieve even application. However, the need for a positioning plate and its fixation often necessitates two people to perform the sealing work, making it cumbersome. Maintaining constant contact between the scraper and the plate to ensure correct application requires skilled personnel, is time-consuming and labor-intensive, results in poor work quality, and poses safety hazards.

[0009] During the application process, the surface of the guide plate opposite to the coating plate abuts against the surface of the outer frame of the windshield facing away from the windshield glass.
[0010] The front-back direction is the direction of application and movement of the weather sealing tool used for aircraft windshields, and the first direction, the front-back direction, and the vertical direction are all perpendicular to each other.

[0028] In the diagram, 100 is a weather sealing tool for aircraft windshields; 1 is a guide plate; 2 is a coating plate; 3 is a deflector plate; and 4 is a scratch-resistant plate. Detailed Implementation
[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0030] like Figures 1-4As shown, an embodiment of the present invention provides a weather sealing tool 100 for aircraft windshields, which includes a guide plate 1 and a coating plate 2.
[0031] The coating plate 2 is vertically arranged and extends along the first direction X. The lower surface of the coating plate 2 is an upwardly concave arc shape. The lower surface of the coating plate 2 is inclined from back to front and upward along the front-back direction.
[0032] The guide plate 1 is fixed to one side of the coating plate 2 in the first direction X and extends forward in the front-back direction; the lower surface of the guide plate 1 is flush with one end of the lower surface of the coating plate 2 and parallel to the front-back direction; the side surface of the guide plate 1 opposite to the coating plate 2 is parallel to the front-back direction.
[0033] When applying the coating, the surface of the guide plate 1 opposite to the coating plate 2 abuts against the surface of the outer frame of the windshield facing away from the windshield glass.
[0034] The front-back direction is the direction of application and movement of the weather sealing tool used for aircraft windshields, and the first direction X, the front-back direction and the vertical direction are perpendicular to each other.
[0035] Based on the above technical solution, the guide plate 1 fixed on one side of the coating plate 2 in the first direction X, opposite to the coating plate 2, is used to abut against the side surface of the windshield outer frame facing away from the windshield glass, so that the coating plate 2 and the outer surface of the windshield glass are placed at an acute angle, so that the lower surface of the coating plate 2 is inclined to squeeze the sealant. By moving the weather sealing tool 100 for the aircraft windshield in the front-back direction, the lower surface of the coating plate 2 is inclined to push and apply the sealant. Through the abutment between the guide plate 1 and the outer frame of the windshield, the side surface of the outer frame of the windshield protruding from the aircraft body is used as the positioning guide reference, thereby eliminating the need to set a positioning plate, thus saving labor costs, simplifying operation and making it easier to ensure the quality of coating and maintenance.
[0036] Furthermore, such as Figures 1-4 As shown, the weather sealing tool 100 for aircraft windshields also includes a deflector plate 3; the deflector plate 3 is fixed to the side of the coating plate 2 away from the guide plate 1 in the first direction X; the deflector plate 3 extends forward in the front-rear direction, and the lower surface of the deflector plate 3 is flush with one end of the lower surface of the coating plate 2.
[0037] It is understood that a gap is formed between the surfaces of the guide plate 3 and the guide plate 1 to guide the sealant to flow in the front-back direction rather than in the first direction X to one side, so that when the weather sealing tool 100 for aircraft windshields applies sealant in the front-back direction, it can guide and push excess sealant forward for use in subsequent sealant applications.
[0038] Furthermore, such as Figures 1-4 As shown, the surface of the guide plate 3 facing away from the guide plate 1 is parallel to the front-back direction; in the front-back direction, the size of the guide plate 3 in the first direction X gradually decreases in the direction away from the coating plate 2.
[0039] It is understood that the surface of the guide plate 3 facing away from the guide plate 1 is parallel to the front-back direction to facilitate the positioning and processing of the guide plate 3. In the front-back direction, the size of the guide plate 3 in the first direction X gradually decreases in the direction away from the coating plate 2, so that the gap formed between the opposing surfaces of the guide plate 1 and the guide plate 3 gradually increases in the front-back direction to guide the sealing adhesive to move forward.
[0040] Furthermore, such as Figures 1-4 As shown, since the lower end of the guide plate 3 is the main functional part, in order to save materials and reduce production costs, the dimensions of the guide plate 3 in the front-to-back direction gradually decrease from bottom to top.
[0041] Furthermore, such as Figures 1-4 As shown, since the lower end of the guide plate 1 is the main functional part, in order to save materials and reduce production costs, the dimensions of the guide plate 1 in the front-to-back direction gradually decrease from bottom to top.
[0042] Furthermore, such as Figures 1-4 As shown, the weather sealing tool 100 for aircraft windshields also includes a scratch-resistant plate 4;
[0043] The anti-scratch plate 4 is fixed to the rear surface of the coating plate 2. The lower surface of the anti-scratch plate 4 is parallel to the front-back direction, and the lower surface of the anti-scratch plate 4 is flush with the rear end of the lower surface of the coating plate 2.
[0044] It is understandable that the lower surface of the coating plate 2 is inclined from back to front and upward along the front-back direction, so that the rear end of the lower surface of the coating plate 2 and the rear surface form a small acute angle. If the force is not applied properly, the coating plate 2 may easily penetrate the sealant and scratch the windshield under the sealant. However, by fixing the anti-scratch plate 4 on the rear surface of the coating plate 2, and making the lower surface of the anti-scratch plate 4 flush with the rear end of the lower surface of the coating plate 2 and parallel to the front-back direction, the rear end of the lower surface of the coating plate 2 and the lower surface of the anti-scratch plate 4 are connected and transitioned, avoiding the formation of a small acute angle that could scratch the windshield during the coating process.
[0045] Furthermore, such as Figures 1-4 As shown, the size of the coating plate 2 in the first direction X is larger than the size of the guide plate 1 in the first direction X; this ensures that the area coated by the coating plate 2 in the first direction X meets the sealing requirements, and controls the size of the guide plate 1 in the first direction X within a certain range to save materials and reduce production costs.
[0046] Preferably, the weather sealing tool 100 for aircraft windshields is manufactured by a 3D printing molding equipment, which is a CNC 3D plastic printer; this ensures that the weather sealing tool 100 for aircraft windshields has high dimensional accuracy, thereby making the sealing adhesive obtained after the application process denser and smoother.
[0047] Furthermore, the weather sealing tool 100 for aircraft windshields is made of polyethylene; compared to tools made of metal, polyethylene has lower rigidity, which greatly reduces the possibility of the weather sealing tool 100 damaging the windshield surface during the application of sealing adhesive, thereby improving the safety of the application process.
[0048] Preferably, such as Figures 1-4 As shown, the rear surface of the deflector plate 3 is flush with the rear surface of the guide plate 1, and the dimension of the deflector plate 3 in the front-rear direction is larger than that of the guide plate 1 in the front-rear direction. This reduces the possibility of the sealing adhesive flowing along the first direction X and flowing from the side of the deflector plate 3 to the windshield when the weather sealing tool 100 for aircraft windshield pushes and applies the sealing adhesive, thereby improving the flatness and aesthetics of the sealing adhesive.
[0049] The working process of this utility model is as follows: the coating plate 2 is placed at an angle, and the guide plate 1 abuts against the side surface of the windshield outer frame facing away from the windshield glass. The guide plate 1 is kept in contact with the windshield outer frame and moves along the extension direction of the windshield outer frame. The sealing adhesive is squeezed and pushed by the lower surface of the coating plate 2, and the sealing adhesive is guided to move along the coating movement direction by the guide plate 3. Then, the sealing adhesive is applied and sealed by the weather sealing tool 100 for aircraft windshields.
[0050] In summary, this utility model embodiment provides a weather sealing tool 100 for aircraft windshields, which includes a guide plate 1 and an application plate 2. The guide plate 1, fixed to one side of the application plate 2 in the first direction X, has its opposite surface abutting against the outer surface of the windshield frame facing away from the windshield. The application plate 2 is placed at an acute angle to the outer surface of the windshield, so that the lower surface of the application plate 2, which is inclined, squeezes the sealing adhesive. By moving the weather sealing tool 100 for aircraft windshields in the front-back direction, the lower surface of the application plate 2, which is inclined, pushes and applies the sealing adhesive. Through the contact between the guide plate 1 and the outer frame of the windshield, the surface of the outer frame of the windshield protruding from the aircraft body is used as a positioning guide reference, thereby eliminating the need for a positioning plate, saving labor costs, simplifying operation, and making it easier to ensure the quality of application and maintenance.
[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
