[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 、 Figure 2 and Figure 3, an embodiment provided by the present utility model: a car door footrest, including the car bottom 2 of the elevator. A connecting block 35 for supporting and connecting the support rod 34 is fixedly installed at the bottom end of the car bottom 2. A support block 33 and a support rod 34 of the footrest 1 are fixedly installed at the bottom end of the connecting block 35. The support rod 34 is arranged in an inclined shape. By being arranged in an inclined shape, the direction of force transmission can be changed, so that the supporting force can be more evenly distributed on the supported structure, enhancing the overall supporting stability. The right side of the rear end of the support rod 34 is fixedly installed with a support block 33 that cooperates with the support rod 34 and the connecting block 35 to support the footrest 1 through a bolt 37 that connects the support rod 34 and the support block 33. The support block 33 is arranged in an L shape. By being arranged in an L shape, it can cooperate with the bolt 37 to connect the support rod 34, and at the same time, it can be installed between the horizontal reinforcing rib 3 and the bottom plate 36 to provide connection and support.

[0031] Further, a footrest 1 is fixedly installed on the rear surface of the car bottom 2 to provide protection and prevent passengers from accidentally getting their feet stuck in the gap between the car and the floor when entering and leaving the elevator, thus avoiding serious injury accidents. A support assembly is arranged below the front surface of the footrest 1 near the car bottom 2. The support assembly includes a horizontal reinforcing rib 3 that enhances the structural stability and strength of the footrest 1. A bottom plate 36 that cooperates with the horizontal reinforcing rib 3 to support the support block 33 is fixedly connected below the front surface of the footrest 1 near the horizontal reinforcing rib 3. A limiting assembly is arranged between the horizontal reinforcing rib 3 and the bottom plate 36. The limiting assembly includes a limiting frame 4 that provides support and limitation. The limiting frame 4 is arranged in an inverted U shape. By being arranged in an inverted U shape, after sliding to the left side of the bolt 37 and the right side of the support block 33, the bolt 37 and the support block 33 can be limited to prevent the bolt 37 from loosening and increase the connection stability of the support block 33.

[0032] Refer to Figure 1 、 Figure 2 and Figure 3 , the support assembly further includes two groups of vertical reinforcing ribs two 32 that enhance the structural stability and strength of the footrest 1, and two groups of horizontal reinforcing ribs 3 are arranged. The two groups of horizontal reinforcing ribs 3 are symmetrically arranged with the center line of the vertical reinforcing rib two 32 as the axis of symmetry. The multiple groups of vertical reinforcing ribs two 32 and the horizontal reinforcing ribs 3 cooperate to enhance the structural stability and strength of the footrest 1.

[0033] Refer to Figure 2 、 Figure 3 and Figure 4, the limit frame 4 is slidably connected to the front surface of the horizontal reinforcing rib 3. The support block 33 slides between the horizontal reinforcing rib 3 and the bottom plate 36. The support block 33 is limited by the cooperation of the horizontal reinforcing rib 3, the bottom plate 36 and the limit rod 45 sliding into the limit groove 43. The top end of the support block 33 is provided with a limit groove 43 that can cooperate with the limit rod 45 to slide into the limit groove 43 to limit the installation of the support block 33. The top end of the inner wall of the limit frame 4 is fixedly connected with a limit rod 45 that slides into the limit groove 43 to connect the support block 33 and the support rod 34. The limit rod 45 penetrates and is slidably connected to the top end of the horizontal reinforcing rib 3. The horizontal reinforcing rib 3 supports the limit rod 45 and the limit frame 4. The limit frame 4 and the horizontal reinforcing rib 3 are elastically connected by a spring 44. The spring 44 is sleeved on the outer wall of the limit rod 45. One end of the spring 44 is fixedly connected to the bottom end of the inner wall of the limit frame 4, and the other end of the spring 44 is fixedly connected to the top end of the horizontal reinforcing rib 3. By pulling up the limit frame 4, the limit rod 45 can be driven to slide out of the limit groove 43 to stretch the spring 44, thus releasing the limit on the bolt 37 and the support block 33, so that the support block 33 can be conveniently removed for later maintenance. At the same time, the reverse force generated by the stretching of the spring 44 can be used to make the limit rod 45 quickly slide into the limit groove 43, improving the convenience of installation and disassembly.

[0034] Refer to Figure 2 , Figure 3 and Figure 4 , a chute 46 for providing space for the movement of the slider 41 is provided on the right side of the limit frame 4. The inner wall of the chute 46 is slidably connected with a slider 41 that can drive the limit frame 4 to move. The right side of the slider 41 is fixedly connected with a guide plate 42 that can drive two groups of sliders 41 to move. The slider 41 and the guide plate 42 are provided so that one group of support blocks 33 can be removed separately, and at the same time, the movement of the guide plate 42 can drive two groups of sliders 41 to move, so that two groups of limit frames 4 can be driven to move at the same time, so that the two groups of support blocks 33 can be conveniently released from the limit at the same time, further improving the convenience of disassembly. There are two groups of the limit frame 4, the support block 33, the support rod 34, the slider 41 and the chute 46, and the two groups of the limit frame 4, the support block 33, the support rod 34, the slider 41 and the chute 46 are symmetrically arranged with the center line of the horizontal reinforcing rib 3 as the axis of symmetry. By setting two groups, the installation stability can be increased.

[0035] Furthermore, at the top end of the horizontal reinforcing rib 3, there are three sets of vertical reinforcing ribs 31 fixedly connected to enhance the structural stability and strength of the foot guard 1. The three sets of vertical reinforcing ribs 31 are all fixedly connected between the two horizontal reinforcing ribs 3. The two sets of vertical reinforcing ribs 32 are symmetrically arranged with the center line of the horizontal reinforcing rib 3 as the axis of symmetry. The two horizontal reinforcing ribs 3 are fixedly connected between the two sets of vertical reinforcing ribs 32. The guide plate 42 is slidably connected to the front surface of the three sets of vertical reinforcing ribs 31. By arranging multiple sets of horizontal reinforcing ribs 3, vertical reinforcing ribs 31 and vertical reinforcing ribs 32 to form a grid-like arrangement and welding them to the front surface of the foot guard 1, the overall structural strength of the foot guard 1 can be enhanced, while meeting the structural strength requirements of the new national standard, and it is more conducive to product standardization and processing production.

[0036] Working principle: During use, when the elevator is running, the foot guard 1 under the car bottom 2 plays a key role in preventing passengers' feet from accidentally getting stuck in the gap. At the same time, the horizontal reinforcing rib 3, vertical reinforcing rib 31 and vertical reinforcing rib 32 in the support assembly are combined to form a grid-like arrangement and welded to the front surface of the foot guard 1, significantly enhancing the overall structural strength of the foot guard 1, enabling it to withstand various external forces and impacts. At the same time, the car bottom 2 is connected to the inclined support rod 34 through the connecting block 35 by bolts 37. This inclined support rod 34 changes the direction of force transmission, making the supporting force more evenly distributed on the supported structure and enhancing the overall supporting stability.

[0037] During maintenance, the L-shaped support block 33 is connected to the support rod 34 by bolts 37 and slides between the horizontal reinforcing rib 3 and the bottom plate 36. When it is necessary to install or disassemble the support block 33, pull up the guide plate 42, driving the slider 41 to move upward at the top end of the inner wall of the chute 46 and pulling up the limit frame 4. At this time, the limit rod 45 in the limit frame 4 slides out of the limit groove 43 at the top end of the support block 33, stretching the tension spring 44, releasing the limit on the bolt 37 and the support block 33, facilitating the removal of the support block 33 and being conducive to later maintenance. When installing, after pulling up the limit frame 4 to drive the limit rod 45 to move upward and stretch the tension spring 44, after installing the support block 33, the reverse acting force of the tension spring 44 being stretched will cause the limit frame 4 and the limit rod 45 to quickly reset and slide into the limit groove 43, quickly installing and limiting the support block 33, thereby improving the convenience of installation and disassembly. At the same time, after the limit frame 4 is reset, since the limit frame 4 is set in a U shape, the left part of the limit frame 4 slides to the left side of the bolt 37, and the right sliding rod of the limit frame 4 slides to the right side of the support block 33, so that the bolt 37 can be limited to prevent the bolt 37 from loosening, and at the same time the support block 33 is supported and limited, improving the stability of installation. Through the coordinated action of each component, the stability and reliability of the foot guard 1 are ensured, and its safety protection function is effectively exerted.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
