Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted ladders, in particular to a hanging ladder for an open carriage. Background Art

[0002] At present, due to the need of unloading or loading goods, light trucks often require personnel to enter the carriage for cooperation. The existing baffles around the carriage are relatively high, generally about 500 mm, making it difficult to climb. At the same time, getting off the vehicle can only be done by jumping directly from the vehicle, which is somewhat dangerous and is not conducive to the up and down movement of personnel and the loading and unloading of goods. Therefore, the hanging ladder for the open carriage is designed to facilitate the climbing of personnel up and down. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a hanging ladder for an open carriage to facilitate the climbing of personnel up and down the carriage.

[0004] The utility model provides the following technical solution: a hanging ladder for an open carriage, including a main body frame, a hook is connected to the main body frame, and the hook is used to hang the main body frame on the carriage. A pedal is connected to the side surface of the main body frame, and the pedal and the hook are respectively located on two side surfaces of the main body frame. A connecting frame is fixed to the side surface of the main body frame, a bolt is fixed inside the connecting frame, and the pedal is sleeved on the bolt and rotates around the bolt. The connecting frame includes a bottom plate and two side plates, the side plates are formed on both sides of the bottom plate, and the bottom plate is located below the pedal to limit the pedal.

[0005] In order to reduce the installation height of the main body frame, the hook is fixed to the upper end of the main body frame.

[0006] In order to improve the bearing capacity of the hook and reduce the deformation of the hook, a hook reinforcing rib is further fixed to the upper end of the hook, and the hook reinforcing rib is fixed to the main body frame.

[0007] In order to reduce the spacing during climbing, the number of pedals is at least two, and the pedals are distributed vertically in sequence.

[0008] In order to improve the stability of the main body frame, a main body reinforcing rib is further fixed inside the main body frame, and the main body reinforcing rib is located inside the pedal.

[0009] In order to make climbing more stable, multiple ribs are further connected inside the pedal, increasing the sole stepping area during climbing.

[0010] In order to prevent the main body frame from damaging the topcoat on the surface of the carriage, a back pad is fixed to the back of the main body frame.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] (1) Hang the main frame on the side wall of the light truck compartment through the hook, and use the connecting frame to support the pedal;

[0013] (2) At the same time, sleeved the pedal on the bolt on the connecting frame, and make the pedal rotate around the bolt, which is convenient to fold the pedal. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Embodiment

[0020] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a hanging ladder for an open carriage, including a main body frame 1, on which a hook 2 is welded. The hook 2 is used to hang the main body frame 1 on the side wall of a light truck carriage. A pedal 4 is connected to the side of the main body frame 1. The pedal 4 and the hook 2 are respectively located on two side surfaces of the main body frame 1. The pedal 4 is used to provide support for a person's feet, facilitating the person to step on the pedal and further facilitating the person to enter the carriage. A connecting frame 3 is fixed to the side of the main body frame 1. A bolt is fixed inside the connecting frame 3, and the pedal 4 is sleeved on the bolt and rotates around the bolt. By rotating the pedal 4 around the bolt, it is convenient to fold the pedal 4 and make the pedal 4 and the main body frame 1 fold and fit together to store the ladder. The connecting frame 3 includes a bottom plate 31 and two side plates 32. The side plates 32 are formed on both sides of the bottom plate 31. The bottom plate 31 is located below the pedal 4, limiting the pedal 4 and at the same time providing support for the pedal 4 to prevent the pedal 4 from rotating downward in the horizontal direction. The ladder of this structure can conveniently fold and store the pedal, and at the same time the connecting frame 3 can provide support for the pedal 4, improving the bearing capacity of the pedal 4 and further facilitating the person to climb the carriage.

[0021] The hook 2 is fixed to the upper end of the main body frame 1, reducing the installation height of the main body frame 1 and further reducing the installation height of the pedal 4, facilitating the person to climb.

[0022] A hook reinforcing rib 5 is further fixed to the upper end of the hook 2. The hook reinforcing rib 5 is fixed to the main body frame 1. By means of the hook reinforcing rib 5, the connection strength between the hook 2 and the main body frame 1 is enhanced, preventing the hook 2 from deforming and enhancing the bearing capacity of the hook 2.

[0023] In this embodiment, the number of pedals 4 is two, and the pedals 4 are distributed vertically in sequence. By setting two pedals 4, the distance between the pedals 4 and the distance between the pedal 4 and the top of the ladder are reduced, facilitating the person to climb.

[0024] A main body reinforcing rib 6 is also fixed inside the main body frame 1. The main body reinforcing rib 6 is located inside the pedal 4. By means of the main body reinforcing rib 6, the rigidity and strength of the main body frame 1 are enhanced, reducing the shaking of the main body frame 1 when a person climbs and improving the climbing experience.

[0025] Multiple ribs 7 are also connected inside the pedal 4. By means of the ribs 7, the strength of the pedal 4 is enhanced, and at the same time the contact area between the pedal 4 and the sole of the foot is increased, making the climbing more stable and safe.

[0026] A back pad 8 is fixed to the back of the main body frame 1. By means of the back pad 8, the main body frame 1 is supported, preventing the main body frame 1 from directly contacting the surface of the carriage and damaging the paint.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
