All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b):
referring to fig. 1 to 5, the present invention provides a technical solution:
an assembled stair, includes braced frame 1, connecting plate 2, ladder board 3, component force pull rod 4, sleeve 5 and cuts formula supporting component 6, wherein:
the two support frames 1 are oppositely arranged, the support frames 1 are formed by butt joint of at least two square rods, so that the length of each support frame 1 can be selected according to the height of a specific mountain slope, the two connecting plates 2 are respectively rotatably installed at two ends of each support frame 1, the two support frames 1 are rotatably provided with the step plates 3, the step plates 3 are matched in the through holes in the support frames 1 through the support rods at two sides of the step plates 3, and the support rods at the side surfaces of the step plates 3 are provided with nuts, so that the angles of the step plates 3 can be limited;
the component force pull rod 4 connects the step plates 3 arranged in the two support frames 1 in series, wherein the component force pull rod 4 is rotationally connected with the step plates 3, so when one step plate 3 deflects with the same angle, the other step plates 3 deflect with the same angle, a locking part for limiting the rotation of the connecting plate 2 is arranged at the joint of the connecting plate 2 and the support frames 1, the locking part consists of a limiting rod 21, a hexagonal sleeve 22 and a spring 23, the limiting rod 21 is arranged on the side surface of the connecting plate 2, the limiting rod 21 can rotate along with the connecting plate 2, the limiting rod 21 can extend and retract in the connecting plate 2 along the direction of the central axis thereof, in particular, a guide block is arranged on the outer circular surface of the limiting rod 21, a guide groove matched with the side surface of the connecting plate 2 is arranged on the side surface of the connecting plate 2, the hexagonal sleeve 22 is arranged at the end part of the limiting rod 21, the hexagonal sleeve 22 is arranged in a six-variable groove, and further can limit the connecting plate 2 to rotate relative to the supporting frame 1, there are springs 23 between the tie rod 21 and the connecting plate 2, both ends of the spring 23 are fixedly connected with the connecting plate 2 and the tie rod 21 respectively, and there are telescopic supporting components between the step plate 3 adjacent to the connecting plate 2 at the bottom and the connecting plate 2 at the bottom, the telescopic supporting component is made up of threaded sleeve 71 and threaded supporting rod 72, the threaded sleeve 71 is set on the connecting plate 2, the threaded supporting rod 72 is screwed in the threaded sleeve 71, its end contacts with step plate 3, so the telescopic supporting component can jack up the step plate 3, achieve the effect of supporting and changing the included angle of the step plate 3 relative to the horizontal direction, the sleeve 5 is sleeved on the square rods butted with each other in the supporting frame 1, the bottom of the sleeve 5 is equipped with the scissors type supporting component 6, it includes the supporting rod 61, the tension wheel 62, two bracing pieces 61 rotate respectively and install the bottom at sleeve 5 and be the setting of cutting formula, and the side of bracing piece 61 is equipped with the take-up pulley 62, two take-up pulleys 62 pass through cable wire 63 and connect, because holistic gravity, consequently, mountain-climbing stair can be to the decurrent pressure of two bracing pieces 61, so two bracing pieces 61 possess the trend of motion to keeping away from each other all the time, and cable wire 63 will pull two bracing pieces 61 and restrict its motion, and then reach fixed effect, contained angle between two bracing pieces 61 takes place corresponding change when cable wire 63's length variation, and then the relative braced frame 1's of bracing piece 61 tip distance changes, can make the tip and the massif contact of bracing piece 61.
The use principle of the invention is as follows: when facing a mountain with different slopes, the included angle between the connecting plates 2 which are horizontally arranged relatively to the supporting frame 1 needs to be changed, and the connecting plates 2 are rotatably connected with the supporting frame 1, so that the angle of the supporting frame 1 can be adjusted freely after the connecting plates 2 are fixed on the mountain, when the angle of the supporting frame 1 is adjusted, the limiting rod 21 is pulled out firstly, the hexagonal sleeve 22 on the limiting rod 21 is separated from the six-deformation groove which is matched with the hexagonal sleeve in the supporting frame 1, then the connecting plates 2 and the supporting frame 1 are in an unlocking state, the angle adjustment can be realized, after the adjustment is finished, the limiting rod 21 is loosened, the limiting rod 21 can shrink towards the inside of the connecting plates 2 under the elastic force of the spring 23, and then the hexagonal sleeve 22 on the limiting rod 21 enters the six-deformation groove which is matched with the hexagonal sleeve in the supporting frame 1 again, and then the position is locked, because the slopes of, therefore, the supporting frame 1 cannot be tiled on a mountain after the supporting frame 1 is adjusted, and the mountain is not a linear inclined plane, so that the distances between the supporting frame 1 and the mountain are different, the included angle between the two supporting rods 61 is correspondingly changed by changing the length of the steel cable 63, the distance between the end parts of the supporting rods 61 and the supporting frame 1 is changed, the end parts of the supporting rods 61 can be in contact with the mountain, the supporting rods 61 can support the supporting frame 1 at multiple points, the supporting frame 1 is prevented from receiving large shearing force when the stair is used, the supporting rods 61 are directly in contact with the mountain, the supporting strength of the stair can be effectively increased, the included angle of the step plate 3 relative to the supporting frame 1 can be adjusted correspondingly to enable a user to walk on the supporting frame because the angle of the supporting frame 1 can be adjusted along with the gradient of the mountain, for example, if the included angle of the step plate 3 with respect to the supporting frame 1 is fixed, the step plate 3 will be inclined downward after the inclined angle of the connecting plate 2 horizontally disposed on the supporting frame 1 is increased, and the user steps on the step plate 3 with a greater downward component force, and is therefore unsafe, then by rotating the threaded sleeve 71, further changing the extension length of the threaded sleeve 71 on the threaded support rod 72, the threaded sleeve 71 will jack up the step plate 3 in contact with the threaded sleeve, at this time, the inclination angle of the step plate 3 relative to the horizontally arranged connecting plate 2 becomes larger, at this time, the step plate 3 is still in a state parallel to the connecting plate 2, thereby increasing the safety of the user when walking on the step plate 3, and the step plate 3 is connected in series through the component force pull rod 4, therefore, when the angle of one of the step plates 3 changes, the rest step plates 3 also change synchronously, thereby facilitating the adjustment of the angle.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
