Abstract
Description
Technical Field
[0001] This utility model relates to the field of passenger boarding stairs technology, specifically to a non-slip step for a passenger boarding stairs. Background Technology
[0002] In the passenger air travel process, passenger boarding stairs play a crucial role. They are the "air bridge" for passengers to go from the waiting area to the aircraft door, and are special ground equipment that ensures passengers can board smoothly. Passengers need to use boarding stairs to complete spatial transfer when boarding and disembarking the aircraft, and their safety importance is self-evident. However, in actual use, boarding stairs have safety hazards that cannot be ignored. In rainy or snowy weather, precipitation will fall directly on the boarding stairs steps. The existing boarding stairs step design has defects in terms of drainage and anti-slip. Water easily accumulates on the step surface, and water forms a water film on the step surface, which greatly reduces the friction between the soles of shoes and the steps. In addition, the existing steps are designed as a whole, which is not convenient for installation and disassembly, and it is not convenient to replace them when they are worn.
[0003] According to the description of a passenger boarding ladder anti-slip step published on the patent website (authorization announcement number: CN218858703U), the passenger boarding ladder anti-slip step includes "anti-slip strips, anti-slip protrusions, and drainage holes" to achieve the anti-slip effect.
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] The passenger boarding ladder's anti-slip steps utilize anti-slip strips, anti-slip protrusions, and drainage holes to achieve an anti-slip effect. During use, these steps are fixed to the boarding ladder steps using bolts and other structures. Over time, corrosion occurs due to rainwater erosion, making installation and disassembly difficult. Furthermore, the lack of an internal slope prevents rainwater from completely draining through the drainage holes, affecting the step's lifespan. Therefore, improvements to these steps are necessary. Utility Model Content
[0006] The purpose of this utility model is to provide a non-slip step for passenger boarding stairs to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip step for a passenger boarding ladder, comprising an anti-slip strip, wherein an anti-slip mechanism is provided at the bottom of the anti-slip strip;
[0008] The anti-slip mechanism includes a step plate, which is fixedly connected to the bottom of the anti-slip strip. An anti-slip block is fixedly connected to the top of the step plate, and a polygonal block is fixedly connected to the top of the step plate. A sliding rod is fixedly connected to the inner side of the step plate, and a movable frame is slidably connected to the outer periphery of the sliding rod. An installation block is fixedly connected to the left side of the movable frame and is slidably connected to the inside of the step plate. A pull block is fixedly connected to the top of the movable frame and is slidably connected to the inside of the step plate. A spring is sleeved around the outer periphery of the sliding rod.
[0009] Preferably, the left side of the spring is fixedly connected to the right side of the movable frame, and the right side of the spring is fixedly connected to the step plate, so as to ensure the stability of the movable frame and the mounting block under the action of the spring.
[0010] Preferably, four polygonal blocks are provided, and the four polygonal blocks are symmetrically distributed on the left and right sides of the top of the step board, so as to enhance the anti-slip effect from different angles.
[0011] Preferably, the slide bar, spring, movable frame, mounting block and pull block are provided in two sets, and the two sets of slide bars, springs, movable frames, mounting blocks and pull blocks are symmetrically distributed on the left and right sides inside the step plate, so that the step plate can be stably installed by setting two sets.
[0012] Preferably, the top of the anti-slip strip, anti-slip block, and polygonal block are respectively provided with anti-slip pads, and the interior of the anti-slip strip and the movable frame are respectively provided with water channels to facilitate the smooth drainage of accumulated water.
[0013] Preferably, the step plate has a water channel inside, which is symmetrically distributed on the left and right sides of the front surface of the step plate, and the bottom of the step plate is inclined, which facilitates the smooth drainage of water inside the step plate through the inclined design.
[0014] Preferably, the step tread includes a support layer, a reinforcing layer is fixedly connected to the periphery of the support layer, an anti-corrosion isolation layer is fixedly connected to the periphery of the reinforcing layer, and an anti-slip layer is fixedly connected to the periphery of the anti-corrosion isolation layer.
[0015] Preferably, the support layer is the innermost layer, which is made of high-strength steel, and the anti-slip layer is the outermost layer, which is made of rubber. Rubber has good anti-slip properties, which can increase the friction when pedestrians walk on the step and prevent slipping accidents.
[0016] Compared with the prior art, this utility model provides a non-slip step for passenger boarding stairs, which has the following beneficial effects:
[0017] 1. The passenger boarding ladder's anti-slip steps utilize an anti-slip mechanism. First, pulling the pull block moves the movable frame inside the step, causing it to slide the mounting block around the slide bar and compress the spring. This allows the step to be placed on the boarding ladder step at its designated installation position. The boarding ladder step has corresponding mounting slots for the mounting blocks. Once stable, releasing the pull block returns the spring to its original position, allowing the movable frame to insert the mounting block into the mounting slot on the boarding ladder step. This facilitates easy installation of the step. The anti-slip blocks, anti-slip strips, and polygonal blocks significantly reduce the risk of passengers slipping during boarding. Multiple polygonal blocks are symmetrically distributed, enhancing the anti-slip effect from different angles, ensuring good anti-slip performance in both dry and humid environments. The anti-slip strips, movable frame, and water channels inside the step form a complete drainage system. In particular, the inclined bottom of the step helps guide accumulated water out smoothly, further improving drainage efficiency.
[0018] 2. The passenger boarding stairs feature anti-slip steps, constructed with a support layer, a reinforcement layer, an anti-corrosion isolation layer, and an anti-slip layer. The support layer, made of high-strength steel, provides strong load-bearing capacity, ensuring it can withstand the pressure of passengers stepping on it and daily use. The reinforcement layer further strengthens the structure, ensuring the stability and safety of the steps. Made of fiberglass reinforced plastic, the reinforcement layer is characterized by high strength, lightweight, and corrosion resistance. The internal fiberglass evenly distributes stress, preventing deformation or cracking of the steps during long-term use. The anti-corrosion isolation layer, made of polyvinyl chloride coating, effectively resists the erosion and corrosion of water, acids, alkalis, and other substances, extending its service life.

[0029] This utility model provides the following technical solution:
[0030] Example 1
[0031] Please see Figure 1-6 This utility model provides a technical solution: a passenger boarding ladder anti-slip step, including an anti-slip strip 1, and an anti-slip mechanism 2 is provided at the bottom of the anti-slip strip 1;
[0032] The anti-slip mechanism 2 includes a step plate 21, which is fixedly connected to the bottom of the anti-slip strip 1. An anti-slip block 22 is fixedly connected to the top of the step plate 21. A polygonal block 23 is fixedly connected to the top of the step plate 21. A sliding rod 25 is fixedly connected to the inner side of the step plate 21. A movable frame 27 is slidably connected to the outer side of the sliding rod 25. An installation block 24 is fixedly connected to the left side of the movable frame 27. The installation block 24 is slidably connected to the inside of the step plate 21. A pull block 28 is fixedly connected to the top of the movable frame 27. The pull block 28 is slidably connected to the inside of the step plate 21. A spring 26 is sleeved around the outer side of the sliding rod 25.
[0033] The left side of the spring 26 is fixedly connected to the right side of the movable frame 27, and the right side of the spring 26 is fixedly connected to the inside of the step plate 21. This ensures the stability of the movable frame 27 and the mounting block 24 under the action of the spring 26. Four polygonal blocks 23 are provided, and the four polygonal blocks 23 are symmetrically distributed on the top left and right sides of the step plate 21, which facilitates the enhancement of the anti-slip effect from different angles.
[0034] Two sets of slide rods 25, springs 26, movable frames 27, mounting blocks 24, and pull blocks 28 are provided. The two sets of slide rods 25, springs 26, movable frames 27, mounting blocks 24, and pull blocks 28 are symmetrically distributed on the left and right sides of the step plate 21. This arrangement allows for stable installation of the step plate 21. Anti-slip pads are provided on the tops of anti-slip strips 1, anti-slip blocks 22, and polygonal blocks 23. Water channels are provided inside anti-slip strips 1 and movable frames 27 to facilitate the smooth drainage of accumulated water. Water channels are also provided inside the step plate 21 and are symmetrically distributed on the left and right sides of the front surface of the step plate 21. The bottom of the step plate 21 is inclined to facilitate the smooth drainage of accumulated water.
[0035] Example 2
[0036] Please see Figure 1-6 Furthermore, based on Embodiment 1, the step tread 21 further includes a support layer 3, a reinforcing layer 4 fixedly connected to the periphery of the support layer 3, an anti-corrosion isolation layer 5 fixedly connected to the periphery of the reinforcing layer 4, and an anti-slip layer 6 fixedly connected to the periphery of the anti-corrosion isolation layer 5. The support layer 3 is the innermost layer and is made of high-strength steel. The anti-slip layer 6 is the outermost layer and is made of rubber. Rubber has good anti-slip properties and can increase the friction when pedestrians walk on the step tread 21, preventing slip accidents.
[0037] In actual operation, when this device is used, first pull the pull block 28, so that the pull block 28 drives the moving frame 27 to move inside the step plate 21. This allows the moving frame 27 to drive the mounting block 24 to slide around the slide rod 25 and compress the spring 26. At this time, the step plate 21 can be placed on the passenger boarding ladder step at the installation position. The boarding ladder step has a corresponding mounting groove for the mounting block 24. When it is stable, release the pull block 28, and the spring 26 will return to its original position. This allows the moving frame 27 to drive the mounting block 24 to be inserted into the mounting groove on the boarding ladder step, thus facilitating the installation of the step plate 21. The anti-slip block 22, anti-slip strip 1, and polygonal block 23 greatly reduce the risk of passengers slipping during boarding. Multiple polygonal blocks 23 are symmetrically distributed to enhance the anti-slip effect from different angles, ensuring good anti-slip performance in both dry and humid environments.
[0038] The anti-slip strip 1, the movable frame 27, and the water channels inside the step plate 21 form a complete drainage system. In rainy or snowy weather, water can be quickly drained through the water channels, preventing water from forming a slippery area on the step surface. In particular, the bottom of the step plate 21 is inclined, which helps to guide water to drain smoothly, further improving drainage efficiency, keeping the step surface dry, enhancing the anti-slip effect, and preventing water from accumulating on the top and inside of the step plate 21.
[0039] The outermost anti-slip layer 6 is made of rubber material, which has good anti-slip properties and can increase the friction when pedestrians walk on the step 21, preventing slip accidents. The support layer 3 is made of high-strength steel, providing strong load-bearing capacity to ensure that it can withstand the pressure of passengers stepping on it and daily use. The reinforcement layer 4 further strengthens the structural strength and ensures the stability and safety of the step structure. The reinforcement layer 4 is made of glass fiber reinforced plastic, which has the characteristics of high strength, light weight and corrosion resistance. The glass fiber inside the material can evenly distribute stress and prevent the step 21 from deforming or cracking during long-term use. The anti-corrosion isolation layer 5 is made of polyvinyl chloride coating material, which can effectively resist the erosion and corrosion of water, acids and alkalis and extend the service life.
