Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

The invention discloses an external hanging type ladder, a sleeping berth and a carriage. A mounting groove is formed in a frame main body, and a pedal assembly is mounted in the mounting groove to form a pedal level; and then, the pedal assembly is stably connected to the frame main body through the connection of a first connecting part and a second connecting part, so that the assembly of the external hanging type ladder is completed, the assembly difficulty is reduced, and the assembly efficiency of the external hanging type ladder is greatly improved. The pedal assembly and the frame bodyare of the two independent structures, and the first connecting part and the second connecting part are detachably connected, when the pedal part is broken or abraded, the pedal part on the pedal assembly can be independently maintained only by disconnecting the first connecting part and the second connecting part, and later maintenance work of the external hanging type ladder is facilitated. Thepedal assembly is located in the mounting groove, the pedal part is prevented from protruding out of the external hanging type ladder, the consistency of the structure of the external hanging type ladder on the overall appearance is guaranteed, and the appearance effect of the external hanging type ladder is greatly improved.
Description
technical field [0001] The invention relates to the technical field of ladders, in particular to an external-mounted ladder, a sleeper and a carriage. Background technique [0002] As a climbing tool, ladders are widely used in daily life. Among them, ladders can be divided into external hanging type and built-in type according to the installation state. The external ladder is hung on the surface of the object, such as: the sleeper of the train, the bed in the dormitory, and some tanks. [0003] On the sleeper berth of the train, the external-hanging ladder usually uses a plurality of steel rods or steel plates to overlap each other, and the steel rods or steel plates are connected to each other by welding. However, such an external ladder requires professional welding techniques, which makes the assembly of the external ladder complicated and seriously affects the assembly efficiency of the external ladder. Simultaneously, when the pedal portion is broken or worn, the who...
