Technical Field
[0001] The utility model relates to the technical field of impregnation processing, in particular to a ladder for a motorhome. Background Art
[0002] The structure of a motorhome is relatively compact. In order to expand the internal usable area of the motorhome as much as possible, various structures that can expand the motorhome compartment have emerged. Subsequently, how to climb from the bottom to the top of the motorhome, how to conveniently repair the equipment on the top of the motorhome, and how to clean the dust on the outer top of the motorhome are all problems that need to be considered by those skilled in the art. Therefore, motorhome ladders have emerged.
[0003] Traditional motorhome ladders are generally movably arranged, with poor installation stability. At the same time, the treads on the ladder are usually anti-slip treated by wrapping rubber anti-slip sleeves. Under long-term exposure to wind, sun, rain and snow, the rubber anti-slip sleeves are prone to breakage, damage and falling off, and repeated climbing will also cause serious wear of the rubber anti-slip sleeves, ultimately affecting the anti-slip performance.

[0026] The following further elaborates on a ladder for a motorhome of the present utility model in conjunction with the accompanying drawings and embodiments of the present utility model.
[0027] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe the present invention in detail with reference to the accompanying drawings and embodiments.
[0028] It should be noted that the terms used herein are only for describing specific implementation modes and are not intended to limit the exemplary implementation modes according to this application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0029] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned accompanying drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the implementation modes of this application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.
[0030] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "beneath" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.
[0031] Please refer to Figures 1 - 10 , the present utility model provides a technical solution: a ladder for a motorhome, comprising: a first upright post 1, a second upright post 2 is arranged outside the first upright post 1, a first cross beam 3 is jointly installed at the tops of the first upright post 1 and the second upright post 2, wing plates 4 are arranged at the edges of the first cross beam 3, a first mounting hole 5 is formed in the first cross beam 3, a pedal 7 is arranged between the first upright post 1 and the second upright post 2, a front guard plate 6 is arranged at the edge of the pedal 7, anti-slip teeth 8 are arranged at the edge of the front guard plate 6 close to the pedal 7, a second cross beam 9 is jointly installed at the bottoms of the first upright post 1 and the second upright post 2, mounting plates 10 are arranged at the edges of the second cross beam 9, and second mounting holes 11 are formed in the mounting plates 10.
[0032] In this example, the wing plates 4 are symmetrically distributed at the edges of the first cross beam 3, and the side view of the wing plates 4 and the first cross beam 3 forms a "C"-shaped structure, which improves the compressive and anti-deformation ability of the first cross beam 3, enabling the first cross beam 3 to bear pressure.
[0033] In this example, the two ends of the wing plates 4 and the first cross beam 3 are respectively welded to the first upright post 1 and the second upright post 2, which improves the connection stability between the wing plates 4 and the first cross beam 3 and the first upright post 1 and the second upright post 2, preventing loosening of the installation.
[0034] In this example, the edge of the pedal 7 and the front guard plate 6 form a 90° bending structure, and the anti-slip teeth 8 are located at the bending corner position of the pedal 7 and the front guard plate 6, which improves the structural strength of the pedal 7 and the front guard plate 6, preventing the pedal 7 and the front guard plate 6 from being bent under pressure, and the setting of the anti-slip teeth 8 can prevent the user from slipping when climbing and stepping.
[0035] In this example, the two ends of the pedal 7 and the front guard plate 6 are respectively welded to the first upright post 1 and the second upright post 2, which improves the connection stability between the pedal 7 and the front guard plate 6 and the first upright post 1 and the second upright post 2, preventing loosening and shaking.
[0036] In this example, both ends of the second cross beam 9 are welded to the first upright post 1 and the second upright post 2 respectively. Anti-slip teeth 8 are also provided at the bending corner position of the second cross beam 9, which improves the stability of the installation of the second cross beam 9 on the first upright post 1 and the second upright post 2.
[0037] Working principle: According to Figures 1 - 10 As shown, first pass the bolt through the first mounting hole 5 on the first cross beam 3 and the second mounting hole 11 on the mounting plate 10 and tighten it on the RV. At this time, the first upright post 1 and the second upright post 2 are completed for installation on the RV through the first cross beam 3 and the mounting plate 10, which improves the use stability. The user can hold the first upright post 1 and the second upright post 2 by hand to climb. The user steps on the second cross beam 9 and the pedal 7 to climb upward. At the same time, wavy anti-slip teeth 8 are provided at the edges of the pedal 7 and the second cross beam 9. During this process, the user's sole contacts the anti-slip teeth 8, which can improve the anti-slip performance and prevent slipping and falling.
[0038] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
