[0030] As Figure 1 The utility model discloses a decoration engineering with the connection relationship diagram of locking pin and spring in the climbing ladder.

[0031] Ladder frame 1 as main structural member is the basic support part of the whole climbing ladder. This component is usually composed of metal frame, has enough strength to bear the expected load. In practical application, the metal frame can select the aluminum profile with certain specification and shape to guarantee that the structure is stable and the weight is reasonable and is conducive to carrying. The upper end and the middle part of ladder frame 1 are provided with connecting nodes for installing the remaining functional components. These connecting nodes not only play the positioning installation role, but also can bear the stress in each direction.

[0032] The adjusting mechanism 2 is installed on the main body of the ladder frame 1, specifically in the middle region between the two sides of the ladder frame 1. The adjusting mechanism 2 contains a freely rotatable hinged component 12, i.e. a rotating shaft, and its two sides are equipped with arc-shaped limit seats. The design of this structure aims to allow users to change the working angle of the ladder by adjusting the position of the hinged component 12, thus meeting the requirements of different environments. In addition, a manual operating device such as a wrench or a rotating wheel is provided at the hinged component 12, allowing workers to accurately control the inclination amplitude as needed.

[0033] The telescopic legs 3 are located at the bottom, which extend vertically along the ladder frame 1 and can move longitudinally relative to the main frame. The inside of the legs has a guide groove that cooperates with the external hand crank or hydraulic control system, thus driving the inner and outer sleeves to perform linear telescopic motion to complete length adjustment. This function ensures stable placement regardless of the terrain. To achieve higher safety and convenience, automatic locking pins can be provided on some specific models of ladders to fix the extended height.

[0034] The steps 4 are distributed in multiple layers with intervals on the front of the entire ladder frame 1, and are arranged horizontally to form part of the climbing channel. There is a certain distance between adjacent two levels to meet the space requirement of comfortable standing for users, while not too large to affect the overall size. The surface can be processed into a grid-like hollow or provided with a strip pattern to facilitate the discharge of water vapor, soil and other debris, improving the clarity of foot feeling.

[0035] The fixed lock 5 is located near the adjusting mechanism 2 and is closely integrated with the latter to form part of a stable system. Its shape is similar to a hook and loop, made of elastic material, with a card slot and tooth block inside to ensure reliability at different working angles. Since it involves multi-point contact locking, the designer has embedded multiple tiny balls in the product to reduce wear and tear and improve lifespan. For the operator, only need to rotate the adjacent manual rod to unlock and release the angle to enter the active range again.

[0036] The non-slip mat 6 is directly placed at the bottom end of the telescopic leg 3 facing the contact surface side, made of soft polymer materials such as rubber. Its presence increases the friction between the ground and the ladder, avoiding the risk of slipping and protecting the safety of the workers.

[0037] The series of structural features described in the present invention collectively solve the problems encountered during construction in narrow and irregular places. In the construction site of decoration engineering, it is often difficult to accurately position and adjust the equipment due to the complex indoor layout. The traditional fixed-angle ladder cannot change its posture in time according to the specific needs, often requiring additional tools or spending time to reconfigure the support frame. However, this new type of ladder can easily adapt to multiple directions without the help of other facilities, thanks to its unique adjusting mechanism 2 and telescopic legs 3. For example, when turning at the corner of a staircase, workers can individually manipulate the hinges with their hands to change the originally straight upward path into a small-angle slope shape that conforms to the space trend, and then further tighten the constraints in each direction to ensure stability. Similarly, when facing uneven land sections, the height of the lower leg section is extended to completely fall to the ground, thereby obtaining a more solid foundation and no longer being affected by the surrounding height difference to hinder normal use.

[0038] In one embodiment, the ladder stand 1 of the decoration engineering ladder of the present application is a whole support structure, which is designed to provide a stable climbing platform for users. The main structure of the ladder stand 1 includes two main beams 7 and several connecting beams 8. The two main beams 7 are arranged parallel to each other to ensure good stability and load-bearing performance of the structure. The connecting beams 8 connect the two main beams 7 transversely, and the entire frame is firmly combined into a solid whole through a number of reasonably distributed connecting pieces 9. The connecting pieces 9 can simplify the assembly process while ensuring the quality of the connection. Such a design not only gives the ladder high stability in various working environments, but also facilitates maintenance.

[0039] For example, in the manufacturing process, high-strength steel is chosen as the main material, and a welding process is used to fix the main beams 7 and the connecting beams 8. The connecting pieces 9 are combined with the above-mentioned components using fastening screws or riveting to achieve a more compact and durable assembly effect. The connection positions are carefully designed, and each node is fully reinforced to ensure that the ladder stand 1 can withstand large external forces without deformation. At the same time, the reasonable spacing between the components also provides necessary installation space and convenience for subsequent other accessories (such as the steps 4, the adjusting mechanism 2, etc.).

[0040] In one embodiment, as shown in FIG. 1, the adjusting mechanism 2 of the decoration engineering ladder of the present application is a multi-directional adjusting mechanism, which is designed to provide a stable and adjustable climbing platform for users. The adjusting mechanism 2 includes a main body 10, a rotating shaft 11, a rotating handle 12, a rotating knob 13, a rotating plate 14, a rotating shaft 15, a rotating handle 16, a rotating knob 17, a rotating plate 18, a rotating shaft 19, a rotating handle 20, and a rotating knob 21. The main body 10 is connected to the ladder stand 1, and the rotating shaft 11 is connected to the main body 10. The rotating handle 12 is connected to the rotating shaft 11, and the rotating knob 13 is connected to the rotating handle 12. The rotating plate 14 is connected to the rotating knob 13, and the rotating shaft 15 is connected to the rotating plate 14. The rotating handle 16 is connected to the rotating shaft 15, and the rotating knob 17 is connected to the rotating handle 16. The rotating plate 18 is connected to the rotating knob 17, and the rotating shaft 19 is connected to the rotating plate 18. The rotating handle 20 is connected to the rotating shaft 19, and the rotating knob 21 is connected to the rotating handle 20. Figure 3As shown, the telescopic support leg 3 of a ladder for decorative engineering projects according to this application has a multi-segment sleeve structure. Each segment of the telescopic support leg 3 is a hollow sleeve, and these sleeves can be nested together to adjust the length. Each sleeve segment is provided with a locking protrusion 10, which can be fixed in the corresponding groove 11 inside the upper sleeve segment, thereby allowing the telescopic support leg 3 to be locked in different positions to ensure stability at different heights. The telescopic support leg 3 is fixed to the bottom of the ladder frame 1, and its bottom end is provided with an anti-slip pad 6 to ensure good friction performance and ensure the stability and reliability of the entire device. This design allows the ladder to quickly adapt to different working height requirements during construction while maintaining stability.

[0041] In another embodiment, the ladder cleverly solves the problem of coordinating height and stability through its design. Specifically, the tight fit between the locking protrusions 10 and grooves 11 on each sleeve section ensures smooth extension and retraction and a secure final position. The outer surface of the telescopic legs 3 is smooth and firmly connected to the ladder frame 1, without affecting the operator's convenience and safety when climbing.

[0042] For example, when the height of the ladder needs to be adjusted, the user can change the overlap of the various sleeve sections by lifting or pushing the telescopic support leg 3. Once the desired height is reached, the user can lock the next sleeve section by inserting the locking protrusion 10 into the corresponding groove 11. This design is simple and effective, greatly improving adjustment efficiency while ensuring safety during use.

[0043] In one embodiment, such as Figure 2 As shown, the hinge component 12 of the adjustment mechanism 2 of a decorative engineering ladder according to this application is made of high-strength alloy material. This material has excellent mechanical properties and weather resistance, enabling the ladder to maintain reliable structural performance even under long-term and high-frequency use. To enhance service life and reliability, a wear-resistant rubber ring 14 is provided at the hinge point 13. The wear-resistant rubber ring 14 effectively reduces metal-to-metal friction between the hinge components 12, reduces wear, and ensures the flexibility of the adjustment mechanism 2 and its stability during long-term use.

[0044] For example, after the hinge component 12 is securely installed with the ladder frame 1, it connects to the top of the telescopic support leg 3 via the built-in wear-resistant rubber ring 14, forming a stable connection structure. This structure allows the telescopic support leg 3 to rotate and adjust at multiple angles around a specific point on the ladder frame 1, and can be locked at different angles using the fixing buckle 5, thus ensuring that the angle of the ladder can be precisely controlled and securely locked. In this way, the ladder can maintain a high degree of flexibility and reliability under various working conditions.

[0045] In one embodiment, the extension leg 3 of the decoration engineering ladder of the present application is set to be no longer than half the length of the main beam 7, which is designed to ensure that the ladder can maintain proper center of gravity under different ground conditions, improving safety and stability in use. This ratio constraint not only optimizes the mechanical properties, but also provides necessary support for the placement and fixation of the ladder. Depending on the actual application environment, the extension leg 3 can be flexibly adjusted to meet different use requirements and occasions. This design scheme is carefully calculated, taking into full consideration various potential factors in the use of the ladder, including load weight, terrain flatness variation, etc. In order to achieve the best safety performance, this ratio limit applies to all relevant application scenarios, from regular indoor decoration to engineering operations in complex outdoor environments.

[0046] Specifically, in one embodiment, by fixing the extension leg 3 at the bottom of the ladder frame 1, length adjustment can be conveniently performed while ensuring that the leg does not become too long to affect the overall center of gravity distribution. For example, when the length of the main beam 7 is fixed, the extension leg 3 can be adjusted to the optimal state of no more than half the length of the main beam 7 according to actual needs. In addition, the leg is configured with a positioning device inside, which can form a stable lock at a specific length, thereby preventing accidental sliding or deformation. In this way, while maintaining sufficient stability, the extension leg 3 can also adapt to different degrees of inclination and undulating ground, ensuring the overall safety of the ladder.

[0047] In one embodiment, continuing to refer to Figure 2 , the fixed lock 5 of the decoration engineering ladder of the present application includes a locking pin 15 and a spring 16. The locking pin 15 is installed inside the fixed lock 5 and can cooperate with the locking hole 17 on the hinged component 12. The spring 16 is located inside the fixed lock 5 on one side of the locking pin 15, providing a spring force to keep the locking pin 15 in the locked position. Specifically, when the hinged component 12 needs to maintain a specific angle, one end of the locking pin 15 will automatically embed into the locking hole 17 of the hinged component 12, maintaining this position unchanged without external force; if the angle of the hinged component 12 needs to be adjusted, only the spring force of the spring 16 needs to be overcome by pressing the locking pin 15 (see Figure 4 ), and the locking pin 15 will be unlocked from the locking hole 17.

[0048] For example, in the design process, first of all, to ensure that the locking pin 15 can be inserted and pulled out of the locking hole 17 smoothly, its diameter is slightly smaller than the locking hole 17, so as to ensure a certain gap to allow slight swing or vibration without causing misoperation. At the same time, by adjusting the pressure of the spring 16 to ensure that the locking is stable and the unlocking is convenient, usually the spring 16 is made of wear-resistant elastic material to meet the frequent operation requirements. The relative movement between the hinged part 12 and the fixed lock 5 is designed to be smooth transition to avoid jamming and ensure the operation performance and durability of the whole structure. On this basis, ensure that each component is installed tightly and stably, and does not affect the safety and stability of the whole ladder.

[0049] In one embodiment, the tread 4 of the decoration engineering ladder of the present application is provided with an abrasive pad 18 (see Figure 1 ). The abrasive pad 18 is installed on each tread 4 and is in full contact with the surface of the tread 4 to ensure that there is no gap or misalignment between them. By adding the abrasive pad 18, the friction between the worker's feet and the tread 4 is increased, thereby effectively improving the safety during operation.

[0050] The tread 4 is the main support point for climbing, and will frequently bear the pressure of human force during use, especially in wet or muddy conditions. Therefore, the specially designed abrasive pad 18 is made of wear-resistant material with a certain roughness to ensure good anti-skid performance and not easy to damage or fall off under long-term high load conditions. This design not only increases safety but also ensures normal use of the equipment in various harsh environments, avoiding safety hazards caused by slippery tread 4.

[0051] For example, from the technical implementation point of view, the abrasive pad 18 is usually fixed to the tread 4 by adhesive. Specifically, the abrasive pad 18 piece is cut and shaped in advance and meets the size requirements, and is placed in the predetermined position. A professional grade adhesive is uniformly applied to the back surface of the abrasive pad 18 and the surface of the tread 4 at the corresponding position, then lightly pressed to make it tightly combined, and finally through a certain curing time to make the abrasive pad 18 firmly attached and not easy to fall off, ensuring that each tread 4 is equipped with effective anti-skid device.

[0052] In one embodiment, with reference to Figure 5 , the anti-skid pad 6 of the decoration engineering ladder of the present application is made of soft high-friction coefficient material and has a metal support plate 19 inside. The anti-skid pad 6 is located at the bottom end of the support leg and is fixedly connected to the support leg by screws. This structure not only prevents the support leg from slipping in wet or dusty environments, but also significantly increases the contact area between the support leg and the ground, improving the stability of the whole ladder.

[0053] The soft high-friction material has good anti-slip performance and can ensure stable contact in various environments, especially suitable for complex ground conditions commonly encountered in decoration engineering construction. The internally configured metal support plate 19 provides additional mechanical strength to prevent deformation during long-term use or under heavy pressure, ensuring long-term reliability. In addition, the connection method fixed by screws is simple and reliable, easy to disassemble, maintain and maintain.

[0054] In terms of technical implementation, specifically, the bottom end of the leg is provided with a pre-set hole for installing the non-slip pad 6. First, the metal support plate 19 is embedded in the non-slip pad 6 to ensure that the two are tightly combined without displacement risk. Then, by passing through the hole on the leg and fastening the screw to the corresponding position on the back of the non-slip pad 6, the installation process is completed. During this process, attention should be paid to ensure that the screw is moderately fastened, which can effectively fix the non-slip pad 6 without damaging the material.

[0055] In one embodiment, a flexible connecting piece 20 is provided between the telescopic leg 3 and the ladder frame 1 of the decoration engineering ladder of the present application (see Figure 1 ). Specifically, the flexible connecting piece 20 is located between the ladder frame 1 and the telescopic leg 3, which can effectively buffer the impact force when the ladder is impacted by external force, avoiding damage to the structure. When the telescopic leg 3 is fixed to the bottom of the ladder frame 1 and the angle adjustment operation is completed by the adjusting device, the position of the flexible connecting piece 20 can provide auxiliary support during this process, thereby improving the convenience and reliability of the operation.

[0056] The flexible connecting piece 20 is usually made of materials with good elasticity, such as rubber or special springs 16. It has good elastic properties and sufficient strength to absorb impact from the outside world, and can stably support the ladder structure to meet the dynamic changes in use. The flexible connecting piece 20 not only plays a role in the case of impact, but also provides necessary support during daily operations such as ladder inclination changes or work platform shifts, preventing deformation or other forms of damage caused by rigid connection.

[0057] In one embodiment, a structure interface for installing the flexible connecting piece 20 can be designed between the ladder frame 1 and the telescopic leg 3. For example, by making the lower part of the ladder frame 1 into a space that can accommodate the elastic element, and designing a limiting device here to keep the position of the element accurate. In this way, whether it is accidental impact during transportation due to bumps or collisions that may occur in actual use, it can effectively rely on these built-in components to play a buffering and protection role. In addition, during the process of adjusting the angle of the ladder frame 1, the flexible connecting piece 20 will follow and work together with the ladder frame 1 and the telescopic leg 3 to form a stable support state, ensuring the safety of the user.

[0058] In actual operation, when the device is in use, the contact height of the ladder with the ground can be adjusted by the telescopic legs 3 to ensure the stability of the ladder under different terrain conditions. Then the worker can adjust the adjusting mechanism 2 according to the needs, quickly change the angle of the ladder by rotating the hinged part 12, and adapt to the operation requirements in complex space. After the angle is adjusted, the ladder is locked at the selected angle position by using the fixed lock 5 to ensure the safety and stability during the climbing process. Then the worker can enhance the friction between the ladder and the ground by setting the non-slip mat 6 at the bottom, further improving the stability. Finally, the worker can use the pedal 4 connected to the ladder frame 1 to climb, realizing efficient and safe operation.

[0059] The exemplary systems and methods of the present application have been specifically illustrated and described hereinabove with the intention of being merely exemplary or illustrative thereof. It is understood that numerous modifications and changes in the actual implementations of the systems and methods described herein can be made by those skilled in the art without departing from the spirit and scope of the application as defined in the appended claims.
