Description

Technical Field

[0001] This utility model relates to the field of tool ladder technology, and in particular to a novel tool ladder with telescopic function. Background Technology

[0002] The new telescopic tool ladder is an innovative climbing aid. It mainly consists of a ladder frame with a telescopic mechanism, a safe and reliable step, and a corresponding adjustment device. The telescopic mechanism can change the overall height of the ladder to adapt to the needs of various working scenarios at different heights. In addition, the structural design takes into account stability, portability, and safety.

[0003] Existing telescopic ladders work by pulling a lever, which unlocks a locking mechanism. Once unlocked, the inner frame is gradually extended. As the inner frame extends, the latch automatically locks at specific points along the extension, temporarily fixing the ladder's height. Users then climb using the footrests. However, over time, the footrests, bearing the weight of the user and the force of their steps, thin out. This compression leads to reduced thickness and deformation, decreasing the flatness of the footrests and affecting the user's comfort and balance, thus increasing the risk of injury while climbing. To mitigate the risks of slipping and falling, current technology utilizes engineering plastics such as polyamide and polycarbonate. These materials possess high strength and hardness, allowing them to withstand greater pressure without easily deforming, thus ensuring the strength of the pedals and providing good anti-slip and comfort. However, during long-term use, especially when exposed to outdoor environments, engineering plastics like polyamide and polycarbonate are affected by ultraviolet radiation. Ultraviolet rays can cause the plastic molecular chains to break, leading to material aging. Aged engineering plastics gradually turn yellow and become brittle, their mechanical properties deteriorate, resulting in surface cracking and detachment of the pedals and reduced strength, thereby increasing the risk of pedal damage. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a novel telescopic tool ladder, comprising a top plate 1. Support columns 2 are fixedly connected at equal intervals to the front of the outer wall of the top plate 1 for fixed support. Multiple foot pedals 10 are fixedly connected at equal intervals to adjacent sides of the outer wall of the support columns 2 for climbing and stepping. Reinforcing ribs 5 are fixedly connected to the left and right sides of the outer wall of each foot pedal 10 to reinforce the overall structural stability. A long support column 7 is rotatably connected to the bottom rear of the top plate 1. Hooks 9 are fixedly connected to the rear of the outer wall of each foot pedal 10. A fixing ring 8 is fixedly connected to the front of the outer wall of the long support column 7. The hooks 9 and fixing ring 8 cooperate to allow the ladder to be stored when not in use. Telescopic legs 14 are fixedly connected at equal intervals to the bottom of the support columns 2. Hand-operated locking hooks 15 are fixedly connected to the front of the outer wall of each telescopic leg 14. Support plates 4 are fixedly connected to the bottom ends of both the long support columns 7 and the telescopic legs 14 to increase the contact area between the ladder and the ground, preventing the ladder from sliding or shifting during use.

[0030] Reference Figure 1 and Figure 2 Each support column 2 has a hanging rack 3 fixedly connected to its top rear side, which facilitates the hanging of tools by workers during work. Multiple semi-circular shaped tubes 12 are fixedly connected at equal intervals to the rear side of the outer wall of the foot pedal 10. Reinforcing ribs 11 are also fixedly connected to the rear side of the outer wall of the foot pedal 10. Since the other end of the reinforcing ribs 11 is triangularly fixed and supported to the semi-circular shaped tubes 12, the reinforcing ribs 11 provide strong support for the semi-circular shaped tubes 12. For support and stability, handrails 16 are fixedly connected to the top of the two support columns 2 on adjacent sides to reinforce the two support columns 2. A pivot is provided on the top plate 1, and limit fixing tubes 101 are provided on both sides of the pivot. A sleeve 102 is provided at the top of the support column 7. The sleeve 102 is fitted on the pivot, and the two sides of the sleeve 102 are close to the limit fixing tubes 101. The limit fixing tubes 101 can prevent the sleeve 102 from swaying left and right and causing the ladder to fall to the ground, so as to ensure the safety of the user.

[0031] Reference Figure 1Multiple triangular support frames 13 are equidistantly fixed to the rear side of the outer wall of the supporting column 7. Reinforcing ribs 6 are fixedly connected to the left and right sides of the outer wall of each triangular support frame 13. Due to the inherent high stability of the triangular structure of the support frames 13, they can effectively disperse forces from all directions. When the supporting column 7 is subjected to external forces, these triangular support frames 13 can evenly transfer and distribute the force to the surrounding structure, preventing deformation or damage to the supporting column 7 due to excessive localized stress. The reinforcing ribs 6 fixedly connected to the outer wall of the triangular support frames 13 further enhance the structural strength of the triangular support frames 13, making them more robust and durable. It can withstand greater external forces and provide strong support for the supporting column 7, thus providing a solid guarantee for the stable operation of the overall ladder structure. A zipper 17 is installed on the rear side of the outer wall of the foot pedal 10. The other end of the zipper 17 is fixedly connected to the front side of the outer wall of the supporting column 7. When the telescopic ladder is extended, the zipper 17 can restrain the ladder sections. When the user climbs the telescopic ladder, the weight of the body will put pressure on the ladder sections. The zipper 17 can prevent the ladder sections from accidentally slipping due to gravity and external forces. A tool rack 18 is installed inside the hanging rack 3. The flat plate on the top of the tool rack 18 can facilitate workers to store and use tools. The two support rods on the rear side can hang hanging bags for workers to use later.

[0032] Working principle: By increasing the width of the foot pedal 10, the wider foot pedal 10 provides users with a wider standing space. During the climbing of the tool ladder, the user's feet can be placed more stably on the foot pedal 10, reducing the risk of body imbalance caused by foot wobbling. Furthermore, the reinforcing ribs 5 on the outer wall of the foot pedal 10 can significantly enhance the structural strength of the foot pedal 10. These reinforcing ribs can withstand greater bending and shearing forces, preventing the foot pedal 10 from deforming and breaking during the user's stepping. The hook 9 on the rear side of the outer wall of the foot pedal 10 works in conjunction with the fixing ring 8 on the front side of the outer wall of the support column 7 to store the ladder when not in use. The red color of the support column 7 serves as a warning in the surrounding environment, thereby avoiding the problem of foot pedals becoming loose and damaged after long-term use.

[0033] The hanging rack 3 is fixedly connected to the top rear side of the support column 2, providing a more convenient hanging position for workers' tools and items, thereby increasing the practicality and functionality of the overall structure. The semi-circular shaped tube 12 on the rear side of the outer wall of the foot pedal 10 provides additional stepping and standing area for workers. Finally, the reinforcing rib 3 11 on the rear side of the foot pedal 10 provides strong support and stability for the semi-circular shaped tube 12 because its other end is fixed and supported in a triangular shape with the semi-circular shaped tube 12. This prevents the foot pedal 10 from deforming and being damaged due to excessive local stress. Whether under frequent stepping or heavy load, the semi-circular shaped tube 12 can ensure the structural integrity and service life of the foot pedal 10, thus achieving the effect of facilitating maintenance personnel to access and store maintenance tools and reinforcing the foot pedal 10 to bear weight.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
