Description

A kind of stair keel structure

The utility model relates to a kind of stair, relates in particular to a kind of keel structure of stair.

The common constitution of general stair has two kinds; One is fixed, and its stair skeleton is to connect with fixed form; Another kind of for spindle hub screws on lift-type, be to be the center with a fixed axis, as keel, each gangboard is risen and forms with spiral dish.The common shortcoming of above-mentioned dual mode is that the keel of stair are fixed.And global design and decoration are particular about in design at present at home, and especially in the shape of the indoor staircase of designed stair of Zhongting or double deck, certain fixed stair are difficult to satisfy the needs at the family of not living together; Simultaneously, the position or the changing unit that occupy family regular meeting change furniture are divided decoration, and for this reason, the stair shape also needs to change the purpose that just can reach global design thereupon.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can arbitrarily adjust the stair shape, and the novel stair keel of the height of adjacent gangboard.

The purpose of this utility model is achieved in that a kind of commutativity of design unit assembly type stair bone dragon.Each unit is made up of cell cube, adjustment seat, clamp and clamp ring; The cell cube end face is provided with an inner sleeve, the bottom surface is provided with an outer tube, adjusts seat and is spirally connected with clamp, and clamp ring, clamp are enclosed within outside the inner sleeve successively, form a unit; The overcoat piping of a last cell cube is placed in outside the clamp of next unit, and uses locked with bolts, forms upper and lower stair keel.

Inner sleeve on the cell cube end face described in the utility model can be spirally connected with cell cube, and the external diameter of this inner sleeve is upper and lower with the footpath, and the upper end has an oblique angle portion; The cell cube bottom surface connects an outer tube, and its internal diameter from top to bottom increases progressively, and forms skew wall; Be provided with slightly outstanding gangboard cushion cap at the cell cube end face.

Adjustment seat described in the utility model is a circular lid shape, and its perisporium is provided with external screw thread, and its end face is provided with a hexagon through hole.

The external diameter of clamp described in the utility model from top to bottom increases progressively the formation skew wall, and internal diameter is upper and lower with the footpath, its upper end be provided with internal thread can with adjust being spirally connected of seat, the bottom isometric axis makes its underpart have contractility to having four grooves.

Its internal diameter of clamp ring described in the utility model increases progressively the formation skew wall from top to bottom, and has a breach and make it have scalability.

The utility model is to adopt the unit of right quantity to be formed by connecting, and the cell cube end face of each unit is provided with an inner sleeve, the bottom surface is provided with an outer tube, adjusts seat and is spirally connected with clamp, and clamp ring, clamp are enclosed within outside the inner sleeve successively, form a unit; The clamp that the overcoat piping of a last cell cube is placed in next unit locks outward, because clamp and clamp ring have contractility, gives clamp and clamp ring pressure, with the inner clamping sleeve pipe, forms upper and lower stair keel.Adjust the relative angle of adjacent cells during assembling, can reach the purpose of adjusting stair keel form; Adjust to adjust the degree of depth that is spirally connected of seat and clamp, can reach the purpose of adjustment gangboard difference in height.

Reaching embodiment in conjunction with the accompanying drawings is further described the utility model;

Accompanying drawing 1, the utility model one block construction schematic diagram;

Accompanying drawing 2, the upper and lower layer of the utility model unit combination figure;

Accompanying drawing 3, the upper and lower layer of the utility model unit combination sectional view;

4 examples of accompanying drawing 4A, accompanying drawing 4B, accompanying drawing 4C, accompanying drawing 4D, the formed connection shape of the utility model;

The structural representation of accompanying drawing 5, the upper and lower fixed end of the utility model;

Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, each unit of the present utility model is made up of cell cube (1), adjustment seat (2), clamp (3) and clamp ring (4), wherein:

Cell cube (1): the end face inner sleeve (11) that is spirally connected, the external diameter of this inner sleeve (11) is upper and lower with the footpath, and the upper end has an oblique angle portion (18); Cell cube (1) bottom surface connects an outer tube (12), and its internal diameter from top to bottom increases progressively, and forms skew wall; Be provided with slightly outstanding gangboard cushion cap (13) at cell cube (1) end face, these gangboard cushion cap (13) central authorities are provided with the fixedly screw (16) of gangboard (5) usefulness of a recess (15) and four, are provided with a perforation (17) in this recess (15) central authorities; In addition, cell cube (1) be spirally connected inner sleeve (11) locate among the centre be provided with a screw (14).

Adjust seat (2): be a circular lid shape, its perisporium is provided with external screw thread (21), and end face is provided with a hexagon through hole (22).

Clamp (3): its external diameter from top to bottom increases progressively the formation skew wall, and internal diameter is upper and lower with the footpath, its upper end be provided with internal thread (31) can with adjust being spirally connected of seat (2), the bottom isometric axis makes its underpart have contractility to having four grooves (32).

Clamp ring (4): its internal diameter increases progressively the formation skew wall from top to bottom, and has a breach (41) and make it have contractility.

When upper and lower two unit combination, adjust seat (2) and be spirally connected with internal and external screw thread (31), (21) with clamp (3); Clamp ring (4) is placed in outside the inner sleeve (11), and this adjustment seat (2) is pressed just and touched clamp ring (4); The outer tube (12) of upper unit body (1) is placed in outside the clamp (3), and bolt (6) is passed outer tube (12), adjusts seat (2) medium pore (17), (22), and the screw (14) central with inner sleeve (11) screws togather, to lock and connect upper and lower Unit two.

In above-mentioned, preceding at lock(ing) bolt (6), can arbitrarily adjust the relative angle of upper and lower two cell cubes (1).Thereby stair keel meander-shaped can arbitrarily form, for example: shape shown in accompanying drawing 4A, 4B, 4C, the 4D.Between outer tube (12) and clamp (3),, clamp (3) is shunk, and compress inner sleeve (11) because the cooperation of inside and outside skew wall forms inside pressure.Simultaneously, because of clamp (3) is enough big to the pressure of inner sleeve (11) Lower Half, but the pressure of the first half still dislikes not enough; Because clamp ring (4) is subjected to downward pressure and outside tension force, and tighten the upper end of compressing inner sleeve (11).Like this, after upper and lower cell cube (1) locking is fixing, promptly can't relatively rotate again or rock.

Preceding at lock(ing) bolt (6), can run through the through hole (17) of cell cube (1) and pass the hexagon through hole (22) of adjusting seat (2) central authorities with hexagonal double-ended bolt, and rotate to adjust the degree of depth that screws togather of seat (2) and clamp (3), make this sleeve pipe (12) make lifting action (promptly drive upper unit body (1) and make descending operation).So, can suitably adjust difference in height between gangboard (5).In practical operation, can suitably highly locate at inner sleeve (11), indicate mark, adjust clamp (3) lifting.

As shown in Figure 5, the utility model must comprise a floor fixture (7) and a top fixture (8) when connecting.One end of this floor fixture (7) changes flat board (71) into, and the inner sleeve (11) that can be spirally connected constitutes.One end of this top fixture (8) changes vertical panel (81) into, and is provided with a downward outer tube (12).One end of this floor fixture (8) can be fixed on ground, and top fixture (8) can be fixed on the wall,

In sum, the utility model not only can be formed the stair keel of various curved shapes, and the difference in height of each adjacent gangboard (5) also can do suitable adjustment easily, reaches the result of use of expection.
