Description

Technical Field

[0001] This utility model relates to the field of ladder technology, and more specifically, to an integrated ladder that is easy to transport. Background Technology

[0002] In the construction industry, ladders are indispensable tools for construction workers to move vertically, and are widely used in various construction projects such as high-rise buildings, bridges, and towers. Whether for exterior wall decoration, equipment installation, or routine inspections, ladders play a crucial role. Traditional ladder designs typically use two parallel square tubes as the main support, connected and fixed in the middle by several crossbars to form a stable frame structure. However, this type of ladder has the problem of inconvenient storage during use and transportation. Due to the large overall frame volume, it not only occupies a lot of space, but also requires special handling and arrangement during transportation and storage. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides an integrated ladder that facilitates transportation, thereby solving the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] An integrated ladder for easy transport includes a main rod and a secondary rod, both of which are cylinders of the same size. The main rod is cut open along its center on its lower side to form a lower plane, while its upper end retains a cylindrical shape. The secondary rod is cut open along its center on its upper side to form an upper plane, while its lower end retains a cylindrical shape. A first groove is formed at the center line of the lower plane, and a third groove is formed at the center line of the upper plane. Several crossbars are hinged between the first groove and the third groove. A support rod is provided at the upper end of the main rod, and a locking structure is provided at the relative position of the secondary rod.

[0006] In an embodiment of this utility model, the diameter of the crossbar is smaller than the width of the first groove and the third groove. The main rod and the auxiliary rod move towards each other until they are completely folded. The lower plane abuts against the upper plane. A plurality of the crossbars are located in the cavity formed by the first groove and the third groove. At this time, the main rod and the auxiliary rod form a cylinder.

[0007] In an embodiment of this utility model, a second groove is provided on the top of the upper end near the side of the auxiliary rod, one end of the support rod is hinged in the second groove, and the other end of the support rod has a notch on the top side.

[0008] In an embodiment of this utility model, an elastic band is provided on the upper end near the top side, and anchors are provided on both sides of the upper end, with the two ends of the elastic band disposed on the anchors.

[0009] In an embodiment of this utility model, a movable hole penetrating the auxiliary rod is provided on the bottom wall of the third groove near the top side, and a movable groove is provided in the middle of the movable hole.

[0010] In an embodiment of this utility model, the locking structure includes a locking shaft, which is movably disposed in the movable hole. A limiting piece is provided on the side of the locking shaft near the center. An abutting spring is provided between the limiting piece and the side of the movable groove away from the main rod. A pull ring is provided at the end of the locking shaft away from the main shaft.

[0011] In an embodiment of this utility model, after the support rod is rotated to be parallel to the top of the auxiliary rod, the locking shaft abuts against the bottom of the support rod.

[0012] In an embodiment of this utility model, a rubber layer is provided on the surface of the locking shaft at the end away from the limiting piece.

[0013] The beneficial effects of this utility model are as follows: Through the external structure of the main rod and the auxiliary rod, and the storage of the crossbar in the groove, a foldable ladder is formed. In the folded state, it can present a smaller cylinder, which greatly saves space. It is easy to operate. Users can easily unfold the ladder from the folded state to the use state without complicated installation process. The optimized design of the support rod and locking structure ensures the stability of the ladder during use. At the same time, the addition of elastic straps allows the support rod to be firmly restrained in the second groove when not in use, which is both beautiful and safe. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] like Figure 1 and Figure 5As shown, this utility model provides an integrated ladder for easy transport, including a main rod 10 and a secondary rod 20. The main rod 10 and the secondary rod 20 are cylinders of the same size. The main rod 10 is cut open along the center on the lower side to form a lower plane 11, and its upper end 13 maintains a cylindrical shape. The secondary rod 20 is the opposite of the main rod 10, cut open along the center on the upper side to form an upper plane 21, and its lower end 23 maintains a cylindrical shape. A first groove 12 is formed at the center line of the lower plane 11, and a third groove 22 is formed at the center line of the upper plane 21. Several crossbars 30 are hinged between the first groove 12 and the third groove 22. A support rod 15 is provided at the upper end 13 of the main rod 10, and a locking structure 24 is provided at the relative position of the secondary rod 20.

[0024] In this embodiment, the diameter of the crossbar 30 is smaller than the width of the first groove 12 and the third groove 22. The main rod 10 and the auxiliary rod 20 move towards each other until they are completely folded, and the lower plane 11 abuts against the upper plane 21. Several crossbars 30 are located in the cavity formed by the first groove 12 and the third groove 22. At this time, the main rod 10 and the auxiliary rod 20 form a cylinder. Compared with the square tube ladder in the prior art, the cylinder has a smaller volume and is easier to transport.

[0025] like Figure 2-3 The upper end 13 shown has a second groove 14 on the side near the auxiliary rod 20. One end of the support rod 15 is hinged in the second groove 14, and the other end of the support rod 15 has a notch 1501 on the side near the top.

[0026] In a preferred embodiment, an elastic band 16 is provided on the upper end 13 near the top side, and anchors are provided on both sides of the upper end 13. The two ends of the elastic band 16 are provided on the anchors. The elastic band 16 is used to restrain the movement of the support rod 15 so that it is always located in the second groove 14 when not in use.

[0027] like Figure 4 As shown, a movable hole 2401 for penetrating the auxiliary rod 20 is provided on the bottom wall of the third groove 22 near the top, and a movable groove 2402 is provided in the middle of the movable hole 2401.

[0028] Furthermore, the locking structure 24 includes a locking shaft 2403, which is movably disposed in the movable hole 2401. A limiting piece 2404 is provided on the side of the locking shaft 2403 near the middle. An abutting spring 2405 is provided between the limiting piece 2404 and the side of the movable groove 2402 away from the main rod 10. A pull ring 2406 is provided at the end of the locking shaft 2403 away from the main shaft. In use, the locking shaft 2403 is pulled outward by the pull ring 2406 so that the rotation trajectory of the support rod 15 is not interfered with by the locking shaft 2403. When the support rod 15 rotates to be parallel to the top of the auxiliary rod 20, the pull ring 2406 is released. At this time, the locking shaft 2403 moves to the bottom of the support rod 15 to form an abutting relationship.

[0029] As a preferred embodiment, a rubber layer is provided on the surface of the locking shaft 2403 away from the limiting piece 2404. The rubber layer protects the bottom of the support rod 15 and prevents it from being subjected to long-term force and accelerated wear.

[0030] Specifically, the working principle of this easy-to-transfer integrated ladder is as follows: Initially, it is a cylindrical structure. To use it, the main rod 10 and auxiliary rod 20 are unfolded until several crossbars 30 are parallel to the main rod 10. Further, the elastic strap 16 is pulled open, allowing the support rod 15 to unfold from the second groove 14. At this time, pulling the pull ring 2406 causes the locking shaft 2403 to retract, ensuring no motion interference occurs on the rotation radius of the support rod 15. When the notch 1501 on the support rod 15 abuts against the top of the third groove 22 of the auxiliary rod 20, the pull ring 2406 is released, and the locking shaft 2403 is engaged by the spring 240. The elastic force of the 5 causes movement until it comes into contact with the bottom of the support rod 15. The support rod 15 ensures that the ladder will not fold automatically during use. After use, pull the pull ring 2406 to return the support rod 15 to the second groove 14. At the same time, adjust the elastic strap 16 to restrain the support rod 15, further folding the main rod 10 and the secondary rod 20, so that several crossbars 30 are located between the cavity formed by the first groove 12 and the third groove 22. Through the above structure, the problem of the large overall frame volume of the existing ladder, the large space occupied, and the inconvenience of storage during use and transportation is solved.

[0031] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
