Description

Technical Field

[0001] The utility model relates to the field of decoration engineering tools, in particular to a novel folding ladder. Background Art

[0002] A ladder is a common tool, usually composed of some horizontal steps and vertical struts, used for climbing or reaching high places. Ladders play an important role in many industries and fields, such as construction, maintenance, cleaning, decoration, warehousing, etc. Whether for household use or commercial applications, the correct use of ladders can improve work efficiency and ensure safety. Ladders include various types for different purposes, among which there are folding ladders. A folding ladder is a ladder that is convenient for storage and carrying, usually composed of multiple foldable struts and steps. Their design allows the ladder to be folded up when not in use.

[0003] Traditional folding ladders usually have multiple foldable segments, enabling users to adjust the height of the ladder according to needs, suitable for workplaces of different heights. The struts of folding ladders are composed of multiple telescopic or foldable materials, usually aluminum alloy or steel. The length of the struts can be adjusted as needed to achieve the telescopic and folding functions of the ladder. The connecting pieces are components that connect the struts together, usually using hinges or other connecting devices. These connecting pieces allow the struts to be freely unfolded or folded when needed and ensure stability and safety during use.

[0004] However, during the use of this kind of folding ladder, since structures such as hinges are used to connect various parts, it often requires cumbersome operations to fix multiple connecting plates to each other. This not only increases the storage of the folding ladder and the pre - use shaking, but also has the problem of difficult maintenance of the connecting pieces, reducing the practicality of this kind of folding ladder. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a novel folding ladder, aiming to improve the problem that traditional folding ladders often require cumbersome operations to fix multiple connecting plates to each other, which not only increases the storage of the folding ladder and the pre - use shaking, but also has the problem of difficult maintenance of the connecting pieces, reducing the practicality of this kind of folding ladder.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A novel folding ladder includes a carbon fiber pedal. A plurality of carbon fiber connecting plates are fixedly connected to the side wall of the carbon fiber pedal. A rotating groove is formed inside the carbon fiber connecting plate. A first rotating shaft is rotatably connected inside the carbon fiber connecting plate. A second rotating shaft is rotatably connected to the side wall of the carbon fiber connecting plate. A rotating component is arranged on the outer wall of the first rotating shaft.

[0007] Further, the rotating component includes a runner, and the runner is fixedly connected to the outer wall of the first rotating shaft.

[0008] Further, the outer wall of the runner is rotatably connected inside the rotating groove.

[0009] Further, the runner is rotatably connected to the outer wall of the second rotating shaft.

[0010] Further, a circular groove is provided inside the runner.

[0011] Further, a clamping plate is fixedly connected inside the runner.

[0012] Further, a plurality of clamping grooves are provided inside the second rotating shaft.

[0013] Further, the outer wall of the clamping plate is slidably connected inside the clamping groove.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, first rotate the carbon fiber connecting plate so that it rotates on the outer wall of the second rotating shaft. The second rotating shaft then drives the runner to rotate, and the rotation of the runner is locked by the engagement of the clamping plate inside the clamping groove, so that the first rotating shaft cannot rotate. Thus, the folding function of the folding ladder can be locked without cumbersome operations, reducing the operation difficulty and pre-shake before use, and improving the practicability of the folding ladder.

[0016] 2. In the utility model, the folding effect of the folding ladder can be achieved through the rotational relationship of a plurality of second rotating shafts between the carbon fiber connecting plates, and the carbon fiber connecting plates can be folded twice through the connection relationship of a plurality of first rotating shafts between the carbon fiber connecting plates, thereby realizing the functional use of the entire folding ladder. Due to the fewer connecting parts between the carbon fiber connecting plates and the repeated collisions, as well as the carbon fiber structure of the folding ladder, the loss of the folding ladder is small, increasing the service life of the folding ladder. It has hardness while being light in weight, convenient to move, and improving flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figure 1 and Figure 2 An embodiment provided by the present invention: a new type of folding ladder, including a carbon fiber pedal 1. A plurality of carbon fiber connecting plates 2 are fixedly connected to the side wall of the carbon fiber pedal 1. A rotating groove 6 is opened inside the carbon fiber connecting plate 2. A rotating shaft 3 is rotatably connected inside the carbon fiber connecting plate 2. A rotating shaft 4 is rotatably connected to the side wall of the carbon fiber connecting plate 2. A rotating component is arranged on the outer wall of the rotating shaft 3.

[0024] Specifically, when using this folding ladder, since it is necessary to lock its folding function, when rotating the carbon fiber connecting plate 2, the outer wall of the rotating shaft 3 drives the rotation of the rotating wheel 5 at the same time. The rotating wheel 5 slides in the rotating groove 6 inside the carbon fiber connecting plate 2. At the same time, as the rotating wheel 5 rotates, the internal clamping plate 8 also follows the displacement. During the movement process, the clamping plate 8 enters the clamping groove 9 inside the rotating shaft 4, thereby clamping the rotating shaft 4. In this way, the locking of the folding function of the folding ladder can be realized without cumbersome operations. This design reduces the operation difficulty and pre-shake before use, and significantly improves the practicability of the folding ladder. This simple and effective locking mechanism enables users to use the folding ladder more easily and enjoy higher safety and convenience during use.

[0025] Refer to Figure 2 and Figure 3 The rotating component includes a rotating wheel 5. The rotating wheel 5 is fixedly connected to the outer wall of the rotating shaft 3. The outer wall of the rotating wheel 5 is rotatably connected inside the rotating groove 6. The rotating wheel 5 is rotatably connected to the outer wall of the rotating shaft 4. A circular groove 7 is opened inside the rotating wheel 5. A clamping plate 8 is fixedly connected inside the rotating wheel 5. A plurality of clamping grooves 9 are opened inside the rotating shaft 4. The outer wall of the clamping plate 8 is slidably connected inside the clamping groove 9.

[0026] Specifically, unfold multiple carbon fiber connecting plates 2 from the folded state. The carbon fiber connecting plates 2 rotate on the outer wall of the second rotating shaft 4 and separate from each other, unfolding into a flat state. Then, fold the carbon fiber connecting plates 2 by rotating them. Through the rotation of multiple first rotating shafts 3 inside the carbon fiber connecting plates 2, the carbon fiber connecting plates 2 can be folded into a semi-surrounding shape. At this time, the folding ladder has a certain strength and can be used to bear weight. Due to the small number of connectors between the carbon fiber connecting plates 2, repeated collisions, and the carbon fiber structure of the folding ladder, its loss is small, thus increasing the service life. While having hardness, it is light in weight, convenient to move, and improves flexibility. These characteristics make this folding ladder perform excellently in various working scenarios and become a practical and reliable tool.

[0027] Working principle: When this folding ladder needs to be used, first unfold multiple carbon fiber connecting plates 2 from the folded state. The carbon fiber connecting plates 2 rotate and separate from each other on the outer wall of the second rotating shaft 4. At this time, the carbon fiber connecting plates 2 are in a flat state. Rotate the carbon fiber connecting plates 2 to fold them. Through the rotation of multiple first rotating shafts 3 inside the carbon fiber connecting plates 2, the carbon fiber connecting plates 2 can be folded into a semi-surrounding shape. At this time, this folding ladder can have a certain strength and can be used to bear weight. Due to the small number of connectors between the carbon fiber connecting plates 2 and repeated collisions, as well as the carbon fiber structure of this folding ladder, the loss of this folding ladder is small, increasing the service life of this folding ladder. While having hardness, it is light in weight, convenient to move, and improves flexibility. Since the folding function needs to be locked when using this folding ladder, when the carbon fiber connecting plates 2 rotate on the outer wall of the first rotating shaft 3, the rotation of the carbon fiber connecting plates 2 can drive the rotating wheels 5 on their outer walls to rotate at the same time. The rotating wheels 5 slide in the rotating grooves 6 opened inside the carbon fiber connecting plates 2. At the same time, the rotation of the rotating wheels 5 drives the clamping plates 8 inside them to move accordingly. The clamping plates 8 enter the clamping grooves 9 inside the second rotating shaft 4 during the movement process, thereby clamping the second rotating shaft 4. Thus, the folding function of this folding ladder can be locked without cumbersome operations, reducing the operation difficulty and pre-shake before use, and improving the practicality of this folding ladder.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
