[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0026] As Figures 1 - 4 shown, the present utility model provides an adjusting paddle for an air outlet grille for aviation, which includes a clamping section 1 and a pushing section 2 connected in sequence. A slot 11 is provided at the first end of the clamping section 1. The slot 11 is in clamping fit with the grille plate 3. The second end of the clamping section 1 bends downward and extends to form the pushing section 2. Frictional projections 21 are provided on a part of the outer wall surface of the pushing section 2.

[0027] The present utility model compactly designs the adjusting paddle as an integrated structure of the clamping section 1 and the pushing section 2. The first end of the clamping section 1 is tightly clamped with the grille plate 3 through the slot 11. The first end of the clamping section 1 naturally bends downward and extends to form the pushing section 2, effectively reducing the space occupied by the whole adjusting paddle, facilitating installation and not causing an additional burden on the space around the air outlet grille. Moreover, frictional projections 21 are provided on a part of the outer wall surface of the pushing section 2, increasing the contact area and friction force between the driver's finger and the pushing section 2, effectively preventing the finger from slipping off, not only improving the accuracy and reliability of the operation, but also optimizing the user experience, making the adjustment process smoother and safer, effectively reducing the operation difficulty, and improving the stability and safety of the adjustment operation.

[0028] Furthermore, the corners of the pushing section 2 are smoothly transitioned to reduce the sharpness of the corners and improve the comfort of use.

[0029] The number of the frictional projections 21 is multiple, and they are arranged in sequence along the length direction of the pushing section 2 to better increase the contact area and friction force between the driver's finger and the pushing section 2.

[0030] As an optional embodiment, the upper end surface and the lower end surface of the grid plate 3 are respectively two-stage stepped structures, including a first step 31 and a second step 32 whose height gradually increases along the direction close to the clamping section 1; the two open ends of the slot 11 are symmetrically provided with sawtooth portions. The sawtooth portion includes a plurality of sawtooth structures, at least one sawtooth structure abuts against the first step 31, and at least one sawtooth structure is clamped with the second step 32, so as to firmly fix the adjustment paddle on the grid plate 3. The remaining inner wall surface of the slot 11 abuts against the end surface of the second step 32 and the outer side surface of the grid plate 3, and this comprehensive contact can improve the stability and reliability of the connection.

[0031] Furthermore, the first step 31 on the upper end surface and the first step 31 on the lower end surface smoothly transition to form an inner side surface, and the second step 32 on the upper end surface and the second step 32 on the lower end surface smoothly transition to form an outer side surface.

[0032] The upper and lower end surfaces of the grille plate 3 have two-level stepped structures respectively, and the two open ends of the slot 11 are symmetrically provided with serrations. The serrations and the multi-point contact cooperation of the two-level stepped structures enable the adjustment paddle to be firmly connected to the grille plate 3. The height change of the two-level stepped structure is also used to guide and fix the adjustment paddle, thereby enhancing the stability and reliability of the connection.

[0033] As an optional embodiment, the longitudinal section of the slot 11 is U-shaped and is adapted to the grid plate 3, so that the slot 11 can be more easily inserted and fixed on the grid plate 3. The U-shaped design of the slot 11 also provides sufficient space to accommodate the serrations and the stepped structure of the grid plate 3 and the outer side of the grid plate 3, thereby improving the tightness and reliability of the connection.

[0034] As an optional embodiment, the sawtooth portion includes a first convex saw tooth 12, a second convex saw tooth 13 and a third convex saw tooth 14 arranged in sequence along the direction close to the toggle section 2, the first convex saw tooth 12 abuts against the end face of the first step 31, and there is a gap between the second convex saw tooth 13 and the end face of the first step 31, and a protruding block 141 is provided in the middle of the first side face of the third convex saw tooth 14, and the protruding block 141 abuts against the end face of the first step 31, and the second side face of the third convex saw tooth 14 is connected to the inner wall of the slot 11 and is clamped at the corner of the second step 32.

[0035] Further, the first convex sawtooth 12, the second convex sawtooth 13 and the third convex sawtooth 14 extend along the width direction of the clamping section 1, and the tips of the first convex sawtooth 12, the second convex sawtooth 13 and the third convex sawtooth 14 are all inclined toward the inside of the slot 11. The first convex sawtooth 12 and the second convex sawtooth 13 are continuously arranged, and the second convex sawtooth 13 and the third convex sawtooth 14 are connected by an inclined surface.

[0036] The tip of the first convex sawtooth 12 abuts against the end surface of the first step 31. There is a gap between the second convex sawtooth 13 and the end surface of the first step 31, and there is no direct contact, allowing a certain adjustment space during the installation process.

[0037] The second side surface of the third convex sawtooth 14 is an inclined surface, and a gap is formed between the side surface of the second step 32. The width of the gap gradually increases toward the end surface close to the first step 31, which is convenient for assembly and disassembly. A raised block 141 is provided in the middle of the first side surface of the third convex sawtooth 14. The raised block 141 abuts against the end surface of the first step 31, further enhancing the stability of the connection. At the same time, the second side surface of the third convex sawtooth 14 is connected to the inner wall of the slot 11 and the corner of the second step 32 to form a multi-point contact fit, ensuring the stable connection of the adjustment paddle on the grille plate 3.

[0038] As an optional embodiment, the cross section of the protrusion 141 is a trapezoid, which increases the contact area between the protrusion 141 and the end surface of the first step 31 to improve the stability and reliability of the connection. The width of the protrusion 141 gradually decreases along the first side surface direction close to the third convex serration 14, so that the protrusion 141 has a certain elastic deformation ability, so that the adjustment paddle can be smoothly inserted and fixed on the grid plate 3.

[0039] As an optional implementation, guide components are respectively provided on the upper end surface and the lower end surface of the grid plate 3. The guide components include guide ridges 4. The guide ridges 4 are symmetrically arranged on both sides of the two-stage stepped structure.

[0040] The guide ridges 4 provide a guide path for the adjusting paddle, and the paddle is smoothly clipped onto the grille plate 3 along the guide ridges 4 .

[0041] As an optional implementation, the connection between the clamping section 1 and the toggle section 2 is smoothly transitioned to improve the overall structural strength.

[0042] As an optional implementation, the angle between the toggle section 2 and the clamping section 1 is 120°, so that the operator can operate the toggle section 2 more smoothly and in accordance with ergonomic principles.

[0043] As an optional implementation, the adjusting paddle is made of polytetrafluoroethylene, which has the characteristics of low friction coefficient, relatively low hardness, relatively high tensile strength and bending strength. It can reduce the friction resistance between the grille plate 3 during installation, so that the adjusting paddle can be easily inserted into the grille plate 3 along the guide ridge 4, and the serrated portion on the adjusting paddle will contact the two-level step structure of the grille plate 3, and generate resistance through physical bite and friction, so that the adjusting paddle is firmly fixed on the grille plate 3.
