Description

Technical Field

[0001] This utility model application relates to the field of aviation handrail technology, specifically a highly stable aviation handrail. Background Technology

[0002] Aircraft armrests are armrest facilities on aircraft seats used to support passengers' bodies. They are usually located on both sides of the seat and are designed to help passengers maintain balance and control seat adjustments, while providing convenient support points. Some aircraft models have adopted a geometrically optimized "paperclip" design to provide shared armrest space for adjacent passengers, improving comfort.

[0003] When using aviation handrails, if users exert excessive force on the handrails, or if users with mobility impairments need to rely heavily on the handrails for support during activities, the handrails need to provide significant support. However, existing aviation handrails have poor stability and support, and cannot effectively provide stable and safe support. Summary of the Invention

[0004] To address the problem that existing aviation handrails cannot effectively provide stable and safe support, this invention provides a highly stable aviation handrail to solve the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A highly stable aviation handrail includes a handrail frame one and a handrail frame two. The handrail frame two is fitted inside the handrail frame one. The side walls of the handrail frame one and the handrail frame two are provided with a plurality of mutually cooperating positioning and mounting holes. The side edges of the handrail frame one and the handrail frame two are provided with a plurality of fixing holes for fixing the handrail frame one and the handrail frame two. The inner side wall of the handrail frame one is fixed with a plurality of positioning protrusions at equal intervals. The inner side of the handrail frame two is provided with a plurality of positioning grooves that cooperate with the positioning protrusions at equal intervals.

[0007] Furthermore, the handrail frame includes a frame plate body, a reinforcing plate frame, and reinforcing ribs. The reinforcing plate frame is welded and fixed to the edge of the frame plate body, and several reinforcing ribs are embedded and fixed inside the frame plate body.

[0008] Furthermore, the second handrail frame has the same internal structure as the first handrail frame, and each of the reinforcing ribs has a reinforcing steel strip embedded inside it. Both the reinforcing steel strip and the reinforcing rib are set in an X shape.

[0009] Furthermore, a number of limiting strips are fixed at equal intervals on the outer side of the second handrail frame, and each limiting strip is fixed with a limiting block on both sides away from the second end of the second handrail frame. A limiting groove is provided on the inner side of the first handrail frame to cooperate with the limiting strips and the limiting blocks.

[0010] Furthermore, each of the limiting grooves is configured as a horizontally placed convex shape that cooperates with the limiting strip and the limiting block, and one edge of each limiting groove is aligned with one edge of the handrail frame.

[0011] Furthermore, each of the limiting strips and positioning grooves is spaced apart, and the thickness of each limiting strip and limiting block is less than the thickness of the first handrail frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the supporting strength of the aviation handrail is increased by reinforcing ribs, and the relative positioning of the first handrail frame and the second handrail frame is limited by positioning protrusions, which facilitates the quick alignment of the first handrail frame and the second handrail frame. This solves the problem that the existing aviation handrails cannot effectively provide stable and safe support, and improves the stability and safety of the aviation handrail during use.

[0014] 2. In this utility model, the limiting strip, the limiting block and the limiting groove are used to further limit the first handrail frame and the second handrail frame, making the connection between the first handrail frame and the second handrail frame more firm and stable, improving the correlation between the first handrail frame and the second handrail frame, thereby further improving the stability of the aviation handrail during use.

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 and Figure 3 A highly stable aviation handrail includes a handrail frame 1 and a handrail frame 2. The handrail frame 2 is fitted inside the handrail frame 1. Several mutually cooperating positioning and mounting holes 3 are opened on the side walls of the handrail frame 1 and the handrail frame 2. Several fixing holes 4 are opened on the side of the handrail frame 1 and the handrail frame 2 for fixing the handrail frame 1 and the handrail frame 2. Several positioning protrusions 5 are fixed at equal intervals on the inner side wall of the handrail frame 1. Several positioning grooves 6 that cooperate with the positioning protrusions 5 are opened at equal intervals on the inner side of the handrail frame 2.

[0023] Specifically, the first handrail frame 1 includes a frame body 11, a reinforcing plate frame 12, and reinforcing ribs 13. The reinforcing plate frame 12 is welded and fixed to the edge of the frame body 11. Several reinforcing ribs 13 are embedded and fixed inside the frame body 11. The second handrail frame 2 has the same internal structure as the first handrail frame 1. Each reinforcing rib 13 has a reinforcing steel strip 14 embedded and fixed inside. The reinforcing steel strip 14 and the reinforcing rib 13 are both set as X-shaped to increase the strength of the positioning mounting holes 3 and fixing holes 4, thereby increasing the reinforcing force of the positioning mounting holes 3 and fixing holes 4 on the first handrail frame 1 and the second handrail frame 2.

[0024] As an optimization solution, such as Figure 3 and Figure 4As shown, several limiting strips 7 are fixed at equal intervals on the outer side of the second handrail frame 2. Each limiting strip 7 has a limiting block 8 fixed on both sides away from the end of the second handrail frame 2. Each limiting strip 7 and the positioning groove 6 are spaced apart. The thickness of each limiting strip 7 and the limiting block 8 is less than the thickness of the first handrail frame 1. The inner side of the first handrail frame 1 is provided with a limiting groove 9 that cooperates with the limiting strip 7 and the limiting block 8. Each limiting groove 9 is set as a horizontally placed convex shape that cooperates with the limiting strip 7 and the limiting block 8. One edge of each limiting groove 9 is aligned with the edge of the first handrail frame 1.

[0025] Specifically, when it is necessary to install handrail frame 1 and handrail frame 2, align each limiting strip 7 and limiting block 8 with the limiting groove 9, align the positioning protrusion 5 with the positioning groove 6, and push handrail frame 1 so that handrail frame 1 is fitted onto the outside of handrail frame 2, so that the positioning mounting hole 3 and fixing hole 4 inside handrail frame 1 and handrail frame 2 are aligned. After alignment, pass the bolts through the fixing hole 4 one by one, and tighten the handrail frame 1 and handrail frame 2 with nuts to assemble and fix handrail frame 1 and handrail frame 2.
