[0002] Kitchen cabinets refer to the platform in the kitchen used for storing kitchen utensils and cooking. Kitchen cabinets are usually composed of five main components, including the cabinet body, doors, hardware, countertop, and appliances. Integrated kitchen cabinets, also known as "integrated kitchens," refer to a combination of cabinets, appliances, gas appliances, and kitchen functional utensils. The doors in the cabinets are usually called cabinet doors, which can seal the cabinets. To meet modern needs, spring-loaded cabinet doors have emerged and are widely used.

[0003] For example, the patent published on the China Patent Network (Publication No.: CN220876296U) describes a foldable step ladder and a multi-functional cabinet.

[0026] 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.

[0027] Please see Figure 1-7 This utility model discloses a step ladder, including a step ladder assembly 2 for installation in a cabinet 1. The step ladder assembly 2 includes a storage box assembly 21 and a storage frame 22 that can be stored and connected in the storage box assembly 21 or moved out of the storage box assembly 21. The storage frame 22 has a storage slot inside, and a step ladder structure 24 can be folded and connected in the storage slot. The step ladder structure 24 can be unfolded in either direction of the storage slot to form an "h" shape. After unfolding, the step ladder structure 24 can be folded upward and stored in the storage slot inside the storage frame 22.

[0028] The step ladder structure 24 includes a step plate 241. One side of the step plate 241 is provided with an integrally formed support frame 242, and the other side of the step plate 241 is provided with an integrally formed step fixing component 243. The support frame 242 and the step fixing component 243 are connected by screws. The step ladder is made of high-strength material and is integrally formed, which has the characteristics of easy processing and installation, lightweight, durability and moisture and rust prevention. The step ladder is connected by screws, which is conducive to processing, installation and subsequent inspection and maintenance. It is suitable for use in a variety of environments. It is designed in combination with the cabinet 1 to improve space utilization and is both beautiful and practical.

[0029] Specifically, the support frame 242 includes a first support plate 2421 and a second support plate 2422 that is assembled and connected to the first support plate 2421 by screws. A metal reinforcing member 27 is provided between the first support plate 2421 and the second support plate 2422. The first support plate 2421 and the second support plate 2422 are interlocked by a locking post 28.

[0030] In this implementation scheme, the step plate 241, support frame 242, and step fixing parts 243 are integrally molded. The step ladder is made of high-strength material and is integrally molded, which has the characteristics of convenient processing and installation, lightweight, durability, and moisture and rust prevention. At the same time, the support plate 2421 and support plate 2422 are interlocked by the clamping post 28, which greatly improves the convenience of processing and installation, and also brings convenience to later inspection and maintenance. The metal reinforcement 27 can enhance the structural strength, improve stability, and increase the load-bearing capacity.

[0031] Specifically, a magnetic post 25 is provided on one side of the support frame 242, and a magnetic post 26 is provided on the inner side of the storage frame 22, which is magnetically connected to the magnetic post 25.

[0032] In this implementation scheme, when the riser structure 24 is folded and stored inside the storage frame 22, the magnetic post 1 25 and the magnetic post 26 are magnetically connected to each other to form a simple locking structure, which is beneficial to the stability of the riser structure 24 when it is stored inside the storage frame 22.

[0033] Specifically, it also includes a safety lock 23 for locking the storage box assembly 21 and the storage frame 22. The safety lock 23 includes a connector 231, which is movably connected to the storage frame 22 via a movable shaft 233. A spring 234 is provided at the bottom of the connector 231, and a limiting protrusion 232 is provided at the top of the connector 231. The top of the limiting protrusion 232 is movably connected to the storage box assembly 21. The connector 231 moves with a lever around the movable shaft 233 as the fulcrum. A pull bead 29 is provided at the top of the support frame 242. When the ladder structure 24 is stored in the storage frame 22, the pull bead 29 and the safety lock 23 are connected to each other. An upper slide rail 211 is provided at the top of the storage box assembly 21, and an upper guide rail 221 is provided at the top of the storage frame 22. The upper slide rail 211 and the upper guide rail 221 are slidably connected by pulleys.

[0034] refer to Figure 5 As shown, when the step ladder structure 24 unfolds from the storage frame 22 into an "h" shape, the safety lock 23 automatically locks: when the step fixing piece 243 is open, the pull ball 29 disengages from the safety lock 23, and the safety lock 23 rotates under the action of the internal spring 234, specifically: the end of the connecting piece 231 near the spring 234 moves downward ( Figure 5 As indicated by the arrow), the end of connector 231 away from spring 234 moves upward ( Figure 5As indicated by the arrow, at this time, the limiting protrusion 232 on the top of the connector 231 moves upward to limit and fix the upper slide rail 211 of the storage box, completing the locking action, so that the storage box assembly 21 and the storage frame 22 cannot slide, thus playing a safety role.

[0035] refer to Figure 6 As shown, when the unfolded ladder structure 24 is folded upwards and stored inside the storage frame 22, the safety lock 23 is in the unlocked state: when the bottom of the pull ball 29 touches the safety lock 23, the safety lock 23 rotates under the action of the top of the pull ball 29, specifically: the end of the connecting piece 231 near the spring 234 moves upwards ( Figure 6 As indicated by the arrow), the end of connector 231 away from spring 234 moves downward ( Figure 6 As indicated by the arrow, at this time, the limiting protrusion 232 at the top of the connector 231 moves downward to unlock the upper slide rail 211 of the storage box, completing the unlocking action, so that the storage box assembly 21 and the storage frame 22 can slide freely.

[0036] A cabinet includes a cabinet 1 and the aforementioned riser ladder.

[0037] When in use, when the user needs to use the step ladder, press the storage frame 22 to pop it out from the storage box assembly 21, and pull the step ladder structure 24 out completely from the storage slot inside the storage frame 22 to unfold the step ladder structure 24. The step ladder structure 24 can be unfolded in two directions as needed, so that the user can unfold the step ladder structure 24 for use as needed, without the need for additional step ladder devices, thus improving practicality.

[0038] When the stepladder is not needed, the stepladder structure 24 can be folded upwards and stored in the storage slot inside the storage frame 22. The storage frame 22 can be pushed into the storage box assembly 21 to complete the storage of the stepladder assembly 2. The stepladder assembly 2 can then be stored in the cabinet 1. The stepladder can be folded and stored in the cabinet 1, which has the advantages of saving space, saving time and effort, and being convenient to use.

[0039] In summary, this step ladder and cabinet are designed with the step ladder made of high-strength material in one piece, similar to high-strength plastic material. It features easy processing and installation, is lightweight, durable, and moisture-proof and rust-proof. The step ladder is assembled and connected with screws, which facilitates processing, installation, and subsequent maintenance. It is suitable for use in various environments. When combined with cabinet 1, it improves space utilization and is both aesthetically pleasing and practical.
