[0002] In the field of IT equipment maintenance, there are a large number of devices of different heights in scenarios such as computer rooms and data centers (such as cabinets of different heights, suspended cable trays, and wiring in the ceiling), which puts forward stringent requirements on the height adaptability, ease of operation and space utilization of maintenance tools.

[0003] Most maintenance ladders lack dedicated storage structures, requiring workers to climb or work with tools such as screwdrivers, network cable testers, and wire strippers. This not only increases physical exertion but also risks equipment damage or personal injury due to tools slipping. A few ladders with storage boards have fixed storage angles (allowing only horizontal placement), making them unsuitable for scenarios such as tilting laptops or inserting testing equipment at an angle, resulting in poor flexibility. Therefore, a foldable IT equipment maintenance ladder is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a foldable IT equipment maintenance ladder, which aims to solve the problem in the prior art that "maintenance ladders lack dedicated storage structures or have fixed storage angles, failing to meet the needs of flexible placement of tools and equipment during IT equipment maintenance".

[0031] 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.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a foldable IT equipment maintenance ladder, including a ladder frame 1. The ladder frame 1 is a common maintenance ladder on the market, bearing the main load-bearing function and providing a climbing support structure for workers. It also serves as the mounting carrier for the extension component 2 and the limiting component 3, ensuring the stable connection of each component. This technology is prior art, so it will not be described in detail. An extension component 2 is provided on the outside of the ladder frame 1, and a limiting component 3 is provided on the outside of the extension component 2. The extension component 2 includes a sleeve 21, which is fixedly connected to the outside of the ladder frame 1. The sleeve 21 provides a sliding track for the extension rod 22 inside, restricting the movement direction of the extension rod 22 so that it can only extend and retract axially, ensuring the stability of the height adjustment process, and also protecting the extension rod 22. The extension rod 22 is slidably connected to the inner wall of the sleeve 21, and can extend and retract by changing its extension length. The height of the adjustable tray 25 is adjusted. A crossbar 23 is fixedly connected to the top of the extension rod 22, serving as a support for the connector 24 and the tray 25, and providing a contact point for the fixing member 27 to ensure that the tray 25 can be stably fixed after the angle is adjusted. The connector 24 is movably connected to the outside of the crossbar 23, realizing the movable connection of the tray 25, allowing the tray 25 to rotate flexibly to adjust the angle. The top of the connector 24 is connected to the tray 25, with a recessed upper part for placing IT maintenance tools, accessories, or small equipment such as screwdrivers and testing instruments, avoiding manual operation by the staff and improving work convenience. A limit member 26 is fixedly connected to the outside of the crossbar 23, which limits the rotation range of the connector 24 through toothed engagement, making it difficult for the tray 25 to slide freely after the angle is adjusted, while also enhancing the connection strength between the tray 25 and the crossbar 23.

[0033] Reference Figure 2 - Figure 4 The limiting member 26 is inserted into the inner wall of the connector 24. The tray 25 is threadedly connected to the inner wall of the connector 24 by a fixing member 27. By tightening the nut, the end of the screw abuts against the outside of the crossbar 23, firmly fixing the tray 25 at the adjusted angle. This prevents the tray 25 from shifting due to vibration or load during use, ensuring the stability of the placed items. The fixing member 27 abuts against the outside of the crossbar 23. Limiting teeth are formed around the outside of the limiting member 26, and these teeth are inserted into the inner wall of the connector 24. The fixing member 27 includes a nut and a screw, with the nut fixedly connected to the top of the screw. Two sets of connectors 24 and limiting members 26 are provided, evenly distributed on the outside of the tray 25 and crossbar 23. This makes the connection between the tray 25 and crossbar 23 more balanced, distributing the load-bearing pressure, improving the load-bearing capacity and safety of the tray 25, and preventing the tray 25 from tilting or being damaged due to single-point force.

[0034] Reference Figure 2 and Figure 5The limiting component 3 includes a housing 31, which is slidably connected to the outside of the sleeve 21. The housing 31 provides installation space and protection for components such as the connector 32 and spring 34, while also restricting the sliding direction of the connector 32, ensuring it can only move towards or away from the extension rod 22. The inner wall of the housing 31 is slidably connected to the inner wall of the sleeve 21 with the connector 32, achieving relative fixation between the extension rod 22 and the sleeve 21, preventing the extension rod 22 from sliding during use. A pull rod 33 is rotatably connected to the inner wall of the connector 32; pulling the pull rod 33 can disengage the connector 32 from the slot 35. The locking of the extension rod 22 is released to facilitate height adjustment. The connector 32 and the outer shell 31 are elastically connected by a spring 34, which provides elastic thrust to the connector 32. This ensures that the connector 32 always tends to move towards the extension rod 22 when there is no external force pulling it, so that it can automatically insert into the slot 35 of the extension rod 22 to complete the locking. The extension rod 22 has a slot 35 on its outer side that is used to engage with the connector 32. By setting multiple slots 35 and distributing them along the length of the extension rod 22, the extension rod 22 can be fixed at multiple height positions, realizing multi-level height adjustment.

[0035] Reference Figure 2 and Figure 5 The lower part of the connector 32 near the extension rod 22 is set with an inclined surface. The lower part of the slot 35 is also set with an inclined surface. The inclined surface at the bottom mates with the inclined surface of the connector 32, facilitating the compression of the connector 32 when the extension rod 22 is adjusted upwards. The lower part of the pull rod 33 is set with a strip-shaped protrusion to limit the pull rod 33. The upper part of the connection between the housing 31 and the pull rod 33 is provided with a through groove for the pull rod 33 to pass through. The strip-shaped protrusion mates with the through groove of the housing 31, which can limit the pull rod 33, prevent the connector 32 from accidentally disengaging from the slot 35, and enhance the locking reliability.

[0036] Working principle: In use, the extension rod 22 can be pulled upwards directly. Since the lower part of the slot 35 of the extension rod 22 and the lower part of the connector 32 near the extension rod 22 are both inclined surfaces, during the pulling process, the inclined surface of the slot 35 will naturally press against the inclined surface of the connector 32, forcing the connector 32 to slide away from the extension rod 22 and compress the spring 34. At this time, the extension rod 22 can rise freely along the inner wall of the sleeve 21 until it reaches the desired height.

[0037] When a slot 35 of the extension rod 22 corresponds to the position of the connector 32, the connector 32 automatically resets under the elastic force of the spring 34, and its end is inserted into the slot 35. The extension rod 22 and the sleeve 21 are relatively fixed through the plug-in engagement, thus completing the height locking.

[0038] To lower the height, simply pull the lever 33 outward. The lever 33 will cause the connector 32 to compress the spring 34 and disengage from the slot 35. At this time, the extension rod 22 can slide down the sleeve 21 under the action of gravity. After releasing the lever 33, the connector 32 will be inserted back into the corresponding slot 35 to complete the fixation. The operation does not require complicated manual unlocking, which is efficient and labor-saving.

[0039] The tray 25 is movably connected to the crossbar 23 via the connector 24. When adjusting the angle of the tray 25, first loosen the fixing part 27, and the nut drives the screw to rotate, so that the end of the screw is separated from the surface of the crossbar 23. At this time, move the connector 24 along the crossbar 23 and rotate the tray 25. When it is rotated to a suitable angle, move the tray 25 in the opposite direction. Since the limiting part 26 is surrounded by limiting teeth, the limiting teeth are inserted and engaged with the inner wall of the connector 24, which restricts the rotation of the connector 24. Tighten the fixing part 27 in the opposite direction, so that the end of the screw is tightly abutted against the outside of the crossbar 23. Through friction and thread locking, the connector 24 and the crossbar 23 are firmly fixed in the horizontal direction.

[0040] When not in use, the extension rod 22 is fully retracted into the sleeve 21 using the height adjustment principle described above, reducing the overall length. At this time, the ladder frame 1 and the retracted extension component 2 form a compact structure, which is convenient for storage or transportation in small spaces such as machine rooms. Throughout the process, the outer shell 31 of the limiting component 3 always protects the internal plug-in component 32, spring 34 and other components. The strip-shaped protrusion at the bottom of the pull rod 33 cooperates with the through groove of the outer shell 31 to prevent the plug-in component 32 from accidentally dislodging, ensuring structural stability in the folded state and preventing components from loosening or falling off.

[0041] 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.
