Detailed Description
In order to more clearly illustrate the embodiments of the present invention, the following description will explain embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
Example 1: the embodiment provides a specific implementation manner of an angle-adjustable stair tread, and the structure of the stair tread is shown in fig. 1 and fig. 2, and the stair tread comprises a support beam 1 and a plurality of groups of leveling treads arranged on the support beam.
Wherein every group is made level the step platform and is all including making level stand 21, step surface 22 and the piece 23 of making level, step surface 22 fixed connection in the top of the stand 21 of making level, and has the face of making level that is used for bearing its self with certain angle in the bottom of the stand 21 of making level. The installation schematic diagram of the leveling block 23 is shown in fig. 3, and is arranged between the leveling upright post 21 and the supporting beam 1, the leveling block 23 is fixed on the supporting beam 1, and the leveling surface of the leveling upright post 21 is fixed on the leveling block 23, so that the leveling upright post 21 is indirectly fixed on the supporting beam 1 by means of the pad of the leveling block 23.
The upper and lower sides of the leveling block 23 are respectively provided with an upper end surface and a lower end surface, the upper end surface is attached to the leveling surface of the leveling upright post 21, the lower end surface is attached to the upper surface of the supporting beam 1, the upper end surface and the lower end surface of the leveling block 23 are not parallel to each other but form a certain included angle with each other, and the included angle is equal to the angle difference between the leveling surface and the supporting beam 1 when the pedal at the top of the leveling upright post 21 is horizontal. Therefore, the leveling block 23 can be used for lining and compensating the angle difference between the leveling surface and the supporting beam 1, so that the pedal can be kept horizontal, and the leveling upright post 21 can be attached to the leveling block 23 and the supporting beam 1 to form a tightly connected whole. The pedestrian applies the pressure that the stair tread applyed through the upright post 21 of making level to find the pressure that becomes to leveling block 23 on leveling block 23 to on applying to a supporting beam from the top completely through the transmission of finding leveling block 23, there is not unsettled atress portion, have outstanding atress performance.
The stair with the adjustable angle of the embodiment can directly produce the supporting beam 1, the leveling upright post 21 and the tread 22 in batch during production, when the angle of the stair is changed, only the leveling block 23 needs to be replaced, the leveling blocks 23 with different included angles of the upper end surface and the lower end surface are selected, so that the leveling upright post 21 can be firmly installed on the supporting beam 1 placed at various angles,
the structure of the leveling upright post 21 and the leveling block 23 can be in various forms, in this embodiment, as shown in fig. 1, the bottom of the leveling upright post has a middle recess and bridging portions protruding from two sides, the recess forms a span of the bridging portions, and the leveling surface is the bottom surface of the recess, that is, the span of the bridging portions.
Make level the both sides of the 21 bridging portion of stand and prolong downwards, extend to a supporting beam 1's side always to form two fixed arms in a supporting beam 1's side, run through fixed arm and a supporting beam 21 by fastener 24, thereby fix the bridging portion on a supporting beam 1, and then will make level stand 21 and a supporting beam 1's relative position lock die, avoid making level stand 21 and drop or the angle change.
Furthermore, sunken hidden groove portions are arranged on two sides of the supporting beam 1, and the fixing arm of the leveling upright post 21 extends into the hidden groove portions and does not protrude out of the hidden groove portions, so that the concealment performance and the attractiveness of the mounting structure are improved.
In addition, in order to further improve the stability of connection and the whole stress performance of the stair tread, an embedded groove is formed in the part, attached to the leveling block 23, of the support beam 1, and the leveling block 23 is located in the embedded groove or a protruding embedded part is arranged to be embedded into the embedded groove. The position of the leveling block 23 is limited by the embedded groove, the leveling block is fixed at the relative position of the supporting beam 1, the leveling block 23 is prevented from loosening and slipping, and the leveling block is always fixed between the leveling upright post 21 and the supporting beam 1.
Above-mentioned structure need choose for use the piece 23 of making level of different up and down terminal surface contained angles when changing the angle of stair installation, just use the angle demand of various stairs in order to only use the piece 23 of making level, will make level the piece 23 and set up to the last piece of making level and the piece of making level down of split type connection, go up to make level the piece and use the pivot to rotate with the same side of the piece of making level down and connect, and go up the piece of making level and dig out one side of the piece of making level downwards, make level down the piece can rotate to being made level the piece and accomodate on. The upper surface of the upper leveling block, which is back to the lower leveling block, is the upper end surface, and the lower surface of the lower leveling block, which is back to the upper leveling block, is the lower end surface. And a plurality of positioning pin holes parallel to the direction of the rotating shaft are formed in the upper leveling block and the lower leveling block, after the upper leveling block and the lower leveling block are placed to a certain fixed angle, the selected certain group of pin holes are in pin joint by using positioning pins, and thus the included angle between the upper end surface and the lower end surface can be fixed at a certain value. Through the design of the leveling block 23 with the structure, only one leveling block 23 is produced, so that the stair with various angles can be applied.
Example 2: the stair tread with the adjustable angle in the embodiment is different from the stair tread in the embodiment 1 in that:
the leveling upright post is not arranged on the supporting beam in a spanning mode, but is provided with a convex inserting strip. The support beam is provided with a sunken insertion groove. The leveling block is a frame shape, a through hole is formed in the center of the leveling block, the inserting strip of the leveling upright post penetrates through the through hole of the leveling block, the frame-shaped leveling block is located below the leveling upright post and surrounds the inserting strip, and then the inserting strip is inserted into the inserting groove of the supporting beam to fix the leveling upright post, the leveling block and the supporting beam.
The above structure is more convenient to mount, and embodiment 1 can be referred to for the rest of the structures.
Example 3: the stair tread with the adjustable angle in the embodiment is different from the stair tread in the embodiment 1 in that:
the support beams are arranged in parallel.
The leveling upright post is provided with a plurality of bridging parts, and the distance between the bridging parts is the same as that between the supporting beams. The stand of making level strides through a plurality of bridging portion and locates on a plurality of supporting beams to utilize a plurality of supporting beams to share pressure, improve the atress performance.
Other structures can refer to embodiment 1.
It should be noted that the above-mentioned embodiments are only detailed descriptions of the preferred embodiments and principles of the present invention, and those skilled in the art will be able to change the embodiments according to the ideas provided by the present invention, and these changes should also be regarded as the protection scope of the present invention.
