[0013] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the description of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] In the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0015] The directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “top”, “bottom”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0016] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0017] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0018] Example

[0019] See also Figure 1 and Figure 2The ladder provided by the present invention comprises a plurality of vertical poles 1, horizontal poles 2, buckles 4 and pedals 3. The vertical poles 1 and the horizontal poles 2 are connected by buckles 4 to form a frame with an opening area. The pedals 3 are assembled on the vertical poles 1 by buckles 4 and are located in the frame.

[0020] It can be known that the number of uprights 1 can be four, and they are arranged in the form of a rectangle at the four corners of the rectangle. The cross bar 2 is connected to the adjacent uprights 1 in sequence through the buckle 4, thereby forming a frame with an opening area. The opening area is convenient when the foot is stepped on the pedal 3 without interfering with the stepping of the foot. The number of pedals 3 can be set as needed, and the height difference between the pedals 3 can be consistent. The pedals 3 are arranged along the height direction of the uprights 1, and the uprights 1 of suitable height can be selected as needed to form a ladder for up and down passages.

[0021] Please continue reading Figure 2 In some embodiments, the frame includes an upright pole 1, a plurality of first cross bars 2 and a plurality of second cross bars, the plurality of first cross bars are connected to the upright pole 1 through buckles 4 to form a supporting plane for supporting the pedal 3, the plurality of second cross bars are connected to the upright pole 1 to form a reinforced plane with an opening, and the reinforced plane is located above the supporting plane.

[0022] It can be understood that the cross bar 2 can include a first cross bar and a second cross bar. The support plane formed by the connection between the first cross bar and the vertical bar can be a rectangular frame plane. The pedal 3 can also be assembled on the buckle 4 by a pin. The number of second cross bars on the same plane is three, which are respectively connected between two adjacent vertical bars 2. Two adjacent vertical bars 1 are not connected, thereby forming an opening, which makes it convenient for the foot to step on the pedal 3. The frame of this structure has good overall stability and is convenient for users to step on.

[0023] See also Figure 2 In some embodiments, the buckle 4 includes a main body, a socket hole and a mounting hole surrounding the socket hole are provided on the main body, the main body is socketed and fixed on the vertical pole 1 through the socket hole, and the cross bar 2 is connected and fixed to the mounting hole on the main body through a pin.

[0024] It is understandable that the main body can be disc-shaped, and the main body is sleeved on the vertical pole 1 through the sleeve hole and welded to the vertical pole 1. A through hole can be set on the cross bar 2, and the pin passes through the through hole on the cross bar 2 and the mounting hole on the main body, so as to realize a quick and fixed connection between the cross bar 2 and the vertical pole 1.

[0025] See also Figure 3 In some embodiments, the cross bar 2 includes a rod body 201 and slot ends 202 provided at both ends of the rod body. The rod body 201 is clamped on the main body through the slot ends 202 and is connected and fixed to the main body through a latch.

[0026] It can be known that the size of the slot end 202 is adapted to the main body. After the slot end 202 is snapped onto the main body, the main body is connected and fixed to the rod body 201 through a latch, which facilitates the connection and fixation of the cross bar 2 and the buckle 4.

[0027] From the above description, it can be known that the ladder provided by the present invention forms a frame with an opening area by connecting the vertical rod 1 and the horizontal rod 2 through the buckle 4. Compared with a simple ladder, it is not easy to slide when placed, the overall stability is better, and the safety during construction is improved.

[0028] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
