Description

Technical Field

[0001] This utility model relates to the field of aircraft manufacturing technology, and in particular to an air direction adjustment handle for an aircraft grille. Background Technology

[0002] In aircraft air conditioning systems, air outlet grilles are mostly composed of multiple horizontal and vertical blades. By adjusting the angle of the horizontal blades using the horizontal adjustment mechanism, the airflow can be guided upwards or downwards. By adjusting the angle of the vertical blades using the vertical adjustment mechanism, the airflow can be guided to the left or right.

[0003] The applicant has discovered that the prior art has at least the following technical problems: When airflow direction needs to be adjusted, two separate adjustment components must be operated to adjust the angles of the horizontal and vertical blades, increasing operational complexity, time-consuming and labor-intensive, and resulting in high production and maintenance costs. Moreover, the two separate adjustment components require additional space for installation and operation, which is detrimental to optimizing the space within the nacelle.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The purpose of this invention is to provide an airflow direction adjustment handle for an aviation grille, addressing the design flaws of existing airflow direction adjustment components in air outlet grilles. These components, which adjust the angles of horizontal and vertical blades as two separate structures, require separate operation of both components when adjusting airflow direction, increasing operational complexity and time costs. The preferred technical solutions provided by this invention offer numerous technical advantages, which are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides an air direction adjustment handle for an aviation grille, comprising a handle body, wherein the handle body is provided with a first slot and a second slot, the first slot extending horizontally through the handle body for connecting a horizontal blade; the second slot extending vertically through the handle body for connecting a vertical blade.

[0007] Preferably, the first slot includes a guide portion and a limiting portion arranged sequentially from the outside to the inside. The inner diameter of the guide portion gradually decreases from the outside to the inside, and the minimum inner diameter of the guide portion is smaller than the inner diameter of the limiting portion. The limiting portion is used to accommodate horizontal blades.

[0008] Preferably, the closed end a of the limiting part is an arc structure and is adapted to the outer end of the horizontal blade; the open end of the limiting part is a straight section structure and has a gap with the inner end of the horizontal blade.

[0009] Preferably, the corners of the guide portion are rounded and smoothly transitioned to the opening end of the limiting portion.

[0010] Preferably, the inner diameter of the second slot gradually decreases from the outside to the inside, the small diameter end of the second slot is an open end, the large diameter end of the second slot is a closed end, and the closed end has an arc-shaped structure.

[0011] Preferably, the second slot extends vertically through the guide portion and is not connected to the limiting portion.

[0012] Preferably, there are multiple second slots, which are spaced apart along the length of the handle body for connecting multiple vertical blades.

[0013] Preferably, multiple parallel first anti-slip protrusions are provided on the upper and lower surfaces of the handle body, and the first anti-slip protrusions extend along the length direction parallel to the handle body.

[0014] Preferably, the two outer corners of the handle body are arc-shaped corners, and multiple parallel second anti-slip protrusions are provided on the arc-shaped corners, with the second anti-slip protrusions extending along the thickness direction parallel to the handle body.

[0015] The preferred technical solution of this utility model can also produce at least the following technical effects: This invention effectively avoids the design flaws of existing air outlet grille air direction adjustment components. In these designs, the adjustment components for horizontal and vertical blades are two independent structures, requiring separate operation of each component to adjust the airflow direction, increasing operational complexity and time costs. This invention provides an aviation air direction adjustment handle for grilles, comprising a handle body with a first slot and a second slot. The first slot extends horizontally through the handle body to connect the horizontal blades; the second slot extends vertically through the handle body to connect the vertical blades. This invention connects both horizontal and vertical blades simultaneously with a single handle body, allowing users to adjust their angles separately with a single operation, greatly simplifying the process, saving time, and improving efficiency. Furthermore, this invention reduces the number of independent adjustment components, eliminating the need for separate installation and operation space for each component, thus optimizing cabin space layout. The reduced number of parts and simplified structure lowers production and assembly complexity, thereby reducing production costs. Simultaneously, the simple structure facilitates easier inspection and replacement of components during later maintenance and repair, reducing maintenance time and costs. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solution of this utility model 1 will be described in detail below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-5 As shown, this utility model provides an air direction adjustment handle for an aviation grille, including a handle body 1. The handle body 1 is provided with a first slot 11 and a second slot 12. The first slot 11 extends through the handle body 1 in the horizontal direction and is used to connect a horizontal blade 2. The second slot 12 extends through the handle body 1 in the vertical direction and is used to connect a vertical blade 3.

[0021] Insert the horizontal blade 2 into the first slot 11 to connect the handle body 1 with the horizontal blade 2. Similarly, insert the vertical blade 3 into the second slot 12 to connect the handle body 1 with the vertical blade 3, thereby establishing a linkage relationship between the handle body 1 and the horizontal blade 2 and the vertical blade 3 respectively.

[0022] When the airflow direction needs to be adjusted, the user only needs to operate the handle body 1. Specifically, when the handle body 1 is moved up and down, the horizontal blade 2 will rotate around its axis under the drive of the first slot 11, changing the angle of the airflow in the vertical direction. When the handle body 1 is moved left and right, the vertical blade 3 will rotate around its axis under the drive of the second slot 12, changing the angle of the airflow in the horizontal direction.

[0023] This invention connects both the horizontal blade 2 and the vertical blade 3 to a single handle body 1. Users can adjust the angles of the horizontal blade 2 and the vertical blade 3 separately by operating this single handle body 1, thereby directing the airflow to the desired direction. This greatly simplifies the operation process, saves time, and improves efficiency. Furthermore, this invention reduces the number of independent adjustment components, eliminating the need to reserve installation and operation space for two separate components, thus optimizing the space layout within the engine compartment. The reduced number of parts and simplified structure lower the complexity of production and assembly, thereby reducing production costs. Simultaneously, the simple structure makes inspection and replacement of parts easier during later maintenance and repair, reducing maintenance time and costs.

[0024] As an optional implementation, the first slot 11 includes a guide portion 111 and a limiting portion 112 arranged sequentially from the outside to the inside. The inner diameter of the guide portion 111 gradually decreases from the outside to the inside, and the minimum inner diameter of the guide portion 111 is smaller than the inner diameter of the limiting portion 112. The limiting portion 112 is used to accommodate the horizontal blade 2.

[0025] Furthermore, the guide portion 111 has a trumpet-shaped structure, so that during the insertion process, the outer end of the horizontal blade 2 will first contact the wider outer opening of the guide portion 111, allowing the horizontal blade 2 to easily enter the guide portion 111. During the insertion process of the horizontal blade 2, it plays a continuous guiding role for the horizontal blade 2, ensuring that the horizontal blade 2 can be inserted into the limiting portion 112 in the correct direction.

[0026] As an optional implementation, the closed end a1121 of the limiting part 112 has an arc structure and is adapted to the outer end of the horizontal blade 2; the open end a1122 of the limiting part 112 has a straight section structure and there is a gap between it and the inner end of the horizontal blade 2.

[0027] When it is necessary to adjust the angle of the airflow in the vertical direction, the user moves the handle body 1 up and down. The handle body 1 slides along the vertical blade 3, driving the horizontal blade 2 to rotate around its axis.

[0028] During rotation, the arc structure of the closed end a1121 of the limiting part 112 always provides stable positioning for the outer end of the horizontal blade 2, improving rotational stability. Simultaneously, the gap between the straight section of the open end a1122 of the limiting part 112 and the inner end of the horizontal blade 2 provides space for the rotation of the horizontal blade 2, preventing interference between the horizontal blade 2 and the open end a1122 of the limiting part 112 during rotation.

[0029] As an optional implementation, the corners of the guide portion 111 are rounded and smoothly transitioned to the opening end a1122 of the limiting portion 112.

[0030] This design makes the horizontal blade 2 easier to insert, avoiding damage to the blade or handle body 1 caused by sharp edges.

[0031] As an optional implementation, the inner diameter of the second slot 12 gradually decreases from the outside to the inside, the small diameter end of the second slot 12 is an open end, the large diameter end of the second slot 12 is a closed end, and the closed end b121 of the second slot 12 has an arc-shaped structure.

[0032] Furthermore, when the vertical blade 3 is inserted into the second slot 12, the open end b122 of the second slot 12 is tightly connected to the vertical blade 3, and the outer end of the vertical blade 3 is connected to the closed end of the second slot 12. There is a gap between the vertical blade 3 located within the second slot 12 and the inner wall of the second slot 12, providing ample space for the rotation of the vertical blade 3.

[0033] When it is necessary to adjust the angle of the airflow in the horizontal direction, the user moves the handle body 1 left and right. The handle body 1 slides along the horizontal blade 2 and drives the vertical blade 3 to rotate around its axis.

[0034] As an optional implementation, the second slot 12 extends through the guide portion 111 in the vertical direction and is not connected to the limiting portion 112.

[0035] As an optional implementation, there are multiple second slots 12, which are spaced apart along the length of the handle body 1, for connecting multiple vertical blades 3.

[0036] As an optional implementation, multiple parallel first anti-slip protrusions 14 are respectively provided on the upper and lower surfaces of the handle body 1, and the first anti-slip protrusions 14 extend along the length direction parallel to the handle body 1.

[0037] This design increases the friction between the user's hand and the handle body 1, allowing for a better grip on the handle during operation, preventing it from slipping, and improving operational stability and safety.

[0038] As an optional implementation, the two outer corners of the handle body 1 are arc-shaped corners 13, and multiple parallel second anti-slip protrusions 15 are provided on the arc-shaped corners 13. The second anti-slip protrusions 15 extend in a direction parallel to the thickness of the handle body 1.

[0039] The curved corner design 13 makes the handle body 1 more ergonomic and easier for users to grip. The second anti-slip protrusion 15 further increases the friction between the hand and the corner of the handle body 1, providing a better grip when operating the handle, making operation easier and more comfortable.

[0040] Furthermore, the cross-sections of both the first anti-slip protrusion 14 and the second anti-slip protrusion 15 are semi-circular. Because the semi-circular surface is relatively smooth, it increases friction without causing a noticeable scratching sensation on the hand.
