Description

Technical Field

[0001] The utility model relates to the technical field of container house assembly structures, in particular to a folding staircase component for a container-type movable house. Background Art

[0002] With the acceleration of modern industrialization and urbanization, container mobile houses are increasingly being used in temporary accommodation, office, commercial display and emergency relief due to their high efficiency, environmental protection, flexibility and mobility. Traditional container mobile houses mostly use an integrated staircase structure. Although this structure has certain stability and service life, it has many inconveniences in the actual handling, storage and installation process.

[0003] First, the overall size of the integrated staircase is large, which not only requires special transportation tools during the transfer process, but also often has difficulties in passing through narrow spaces or entrances. This not only increases the transportation cost, but also has poor adaptability in complex environments. Secondly, in terms of storage, this structure is bulky and occupies too much space, resulting in increased storage costs, especially when space is limited.

[0004] In terms of on-site installation, integrated staircases often require the collaboration of multiple people and take a long time, which to a certain extent limits the rapid deployment capability of mobile homes, especially in emergency situations such as disaster relief where rapid construction is required. At the same time, once the installation location is improperly selected or needs to be readjusted, the difficulty and workload of the overall movement will be greatly increased.

[0005] On the other hand, in order to solve the problem of integrated stair parts, some container mobile homes adopt on-site welding and assembly. Although this method improves the transportation and storage efficiency of stair parts, on-site welding and assembly requires professional welding technology and equipment, and the welding process may cause damage to the container structure, affecting its overall strength and service life. In addition, the smoke and noise generated by welding have potential adverse effects on the environment and the health of operators. More importantly, on-site welding is highly dependent on site conditions and the skill level of technicians, which not only increases the difficulty of construction, but also reduces the construction efficiency, affecting the overall construction speed of the mobile home.

[0006] In view of this, the existing container mobile house stair design has many deficiencies, and a new stair design solution is urgently needed to solve the above problems. This new solution needs to take into account the convenience of transportation, storage and on-site installation, while maintaining sufficient stability and safety. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-4 A container-type mobile house folding staircase comprises an upper support frame 11 and a lower support frame 12 which are butt-jointed end to end, the upper support frame 11 and the lower support frame 12 are matched and connected by a hinge 101, and also comprises pedals 2 and support rods 3 which are rotatably mounted and evenly distributed on the upper support frame 11 and the lower support frame 12, the bottom end of the support rod 3 is matched and combined with the pedals 2 through a linkage assembly, the upper support frame 11 and the lower support frame 12 are both equipped with handrails 5, and the handrails 5 are rotatably connected to the top ends of the support rods 3 on the corresponding support frames.

[0031] The upper support frame 11 and the lower support frame 12 are both fixedly connected with positioning seats 102 which are arranged in a close relationship. The positioning seats 102 are provided with positioning pin holes 1021 which are arranged opposite to each other. The two groups of positioning seats 102 are fixedly assembled by positioning bolts which are arranged through the positioning pin holes 1021 .

[0032] The linkage assembly includes a large gear 41 fixed to the support rod 3, a small gear 42 fixed to the pedal 2, and a reversing gear 43 rotatably mounted on the upper support frame 11 and the lower support frame 12. The reversing gear 43 is meshed with the large gear 41 and the small gear 42.

[0033] The upper support frame 11 and the lower support frame 12 have basically the same overall shape and structure. They are made of welded steel plates to ensure their overall structural strength and bearing capacity. Positioning seats 102 are fixed to the bottom of the upper support frame 11 and the top of the lower support frame 12, and hinges 101 are assembled on the bottom surfaces of the upper support frame 11 and the lower support frame 12. When the stair member is in a folded state, the upper support frame 11 and the lower support frame 12 flip around the hinge 101 to a parallel posture. When the support rod 3 rotates from a vertical posture to a parallel posture of the upper support frame 11 and the lower support frame 12, the handrail rod 5 descends in height and fits with the upper support frame 11 and the lower support frame 12. Under the action of the linkage assembly, the pedal 2 can be flipped from its original horizontal posture to a parallel posture of the upper support frame 11 and the lower support frame 12.

[0034] When the staircase is opened and assembled, the upper support frame 11 and the lower support frame 12 are first flipped to the same straight line direction, and the positioning seat 102 is locked and fixed by the positioning bolts to achieve the fixed combination of the upper support frame 11 and the lower support frame 12. The fixed combination of the positioning seat 102 and the positioning bolts can ensure the stability and support strength of the connection position of the upper support frame 11 and the lower support frame 12. Then the support rod 3 is flipped to a vertical state, at which time the handrail rod 5 is raised and kept parallel to the upper support frame 11 and the lower support frame 12, and at the same time, the pedal 2 is in a horizontal posture under the action of the linkage assembly, so that the staircase is fully opened.

[0035] Taking actual application and assembly as an example, the upper support frame 11 and the lower support frame 12 are fixedly connected and arranged at an inclination angle of 30°. Therefore, the inclination angle of the vertically arranged support rod 3 with the upper support frame 11 or the lower support frame 12 is 60°, and the inclination angle of the horizontally arranged pedal 2 with the upper support frame 11 or the lower support frame 12 is 150°. To ensure that the support rod 3 is flipped 60° and parallel to the upper support frame 11 or the lower support frame 12, the pedal 2 can be rotated 150° and parallel to the upper support frame 11 or the lower support frame 12 under the action of the linkage assembly.

[0036] Therefore, the ratio of the number of teeth of the large gear 41 and the small gear 42 needs to be designed to be 15:6, and the setting of the reversing gear 43 can ensure that the support rod 3 and the pedal 2 flip in the same direction.

[0037] In order to ensure that the upper support frame 11 and the lower support frame 12 have their own strength to meet the use requirements and to ensure that the upper support frame 11 and the lower support frame 12 can be stably installed in the container mobile house, the following technical solutions are provided.

[0038] The upper support frame 11 and the lower support frame 12 each include two groups of parallel arranged support side plates 103 and a connecting bottom plate 104 evenly fixed between the two groups of support side plates 103; the upper support frame 11 has an upper connecting seat 105 fixed to the top end, and the lower support frame 12 has a lower connecting seat 106 fixed to the bottom end.

[0039] The setting of the supporting side panels 103 can ensure that the pedals 2 and the supporting rods 3 are stably assembled thereon, and the setting of the connecting base plate 104 can ensure the structural stability of the two sets of supporting side panels 103. The upper connecting seat 105 and the lower connecting seat 106 can be fixed to the container mobile house by bolts to ensure the stable assembly of the stair components and facilitate the passage of people between different floors.

[0040] The positioning seat 102 is fixedly welded to the outer side wall of the supporting side plate 103 to ensure effective support for the upper supporting frame 11 and the lower supporting frame 12 formed.

[0041] In order to ensure that the pedal 2 can be stably installed on the upper support frame 11 and the lower support frame 12 in a relatively rotating manner, and to ensure that the upper support frame 11 and the lower support frame 12 can effectively support the upper pedal 2, the following technical solution is provided.

[0042] The inner wall of the inner side of the supporting side plate 103 is fixedly connected with a transverse supporting seat 107 and an oblique supporting seat 108. One side of the pedal 2 is fixedly connected with a connecting shaft 21. The connecting shaft 21 is rotatably mounted on the supporting side plate 103 and arranged between the transverse supporting seat 107 and the oblique supporting seat 108. A small gear 42 arranged on the outer side of the supporting side plate 103 is fixedly connected to the connecting shaft 21.

[0043] The pedal 2 can stably rotate around the connecting shaft 21.
