Abstract
The utility model relates to a combined spiral stairway used indoors and adopts the technical proposal that the spiral stairway consists of a support upright post, stair treads fixed on the upright post and arranged spirally and stair railing brackets connected with the stair treads. The utility model is characterized in that the support upright post is formed by a plurality of support pipe nipples which are sleeved into a middle upright post; both ends of the middle upright post are fixed on the upper end face and the lower end face of the stairway; each support pipe nipple comprises a circular platform with both ends protruding in radial direction; one end of each stair tread is provided with a circular hole with the diameter equal to the outside diameter of the middle upright post, while the two corners of the other end are provided with circular holes matched with the stair railing brackets; the stair treads are fixed by the circular platforms of an upper support pipe nipple and a lower support pipe nipple after being sleeved into the middle upright post; each stair railing bracket comprises a hack lever and a spiral railing; moreover, the hack lever passes through the outer corner circular holes of the upper stair treads of adjacent stair treads in turn and then is fixed with a stair railing and the inner corner circular hole of a lower stair tread. Adopting the technique, the spiral stairway is simple in installation, firm in use and convenient for adjusting stair tread spacing and can choose different shapes according to needs along with portability and handsomeness.
Description
One, technical field: the utility model relates to a kind of combined staircase, particularly a kind of suitable indoor use combined helical stair.
Two, background technology: existing spiral stairs is that broadstep and handrail directly are fixed on the support post, and the installation difficulty is big, and particularly the broadstep spacing can not be adjusted, and makes troubles to use.
Three, the purpose of this utility model is exactly the problems referred to above that exist at existing fixed structure, the combined helical stair of the indoor use of provide a kind of convenient combination, adjusting easily.The broadstep of helical arrangement and the balustrade support that is connected with pedal were formed on its technical scheme comprised support post and is fixed on column, it is characterized in that: support post is inserted in middle standing pillar by a plurality of support pipe nipples to be formed, the middle standing pillar two ends are fixed on the upper and lower end face of stair, support pipe nipple and comprise that two ends radially protrude by circular platform, broadstep one end is provided with the diameter circular hole suitable with the middle standing pillar external diameter, two corners of the other end are provided with the circular hole that cooperates with armrest support, broadstep is inserted in behind the middle standing pillar by two circular platforms extruding of supporting pipe nipples are fixing up and down, the balustrade support comprises that hack lever and spiral handrail form, and hack lever is fixedlyed connected with the interior corner circular hole of the balustrade and the pedal of going downstairs after passing the outer corners circular hole of the pedal of going upstairs of adjacent broadstep successively.Supporting pipe nipple is made up of top connection, intermediate and lower bolster, the top connection top is a circular platform, be to have externally threaded cylinder below, connect the adjustment nut at the cylinder external screw thread, the slightly larger in diameter of adjusting nut is in the diameter of intermediate, top connection lower cylindrical body directly inserts intermediate, offers circular groove at the upper surface of lower bolster, and pegging graft with the lower surface of intermediate cooperates.The lower edge of adjusting nut is provided with the convex edge, and the convex edge is inserted to form in the intermediate and cooperated.Hack lever comprises elbow, tubing string and following expander composition, elbow upper end hinge fixed block, fixed block is fixedlyed connected with handrail by bolt, the elbow lower external thread is inserted tubing string after connecting expansion nut, insert cone in the middle of the following expander and be threaded with set bolt and cooperate, insert behind the tubing string to cooperate and fix with corner circular hole grafting in the broadstep.Adopt the spiral stairs after this technology to have simple installation, use firmly, conveniently adjust the pedal spacing, and different shaping, light and beautiful can be set as required.
Four, description of drawings:
Fig. 1 is an overall structure sketch of the present utility model;
Fig. 2 is the support pipe nipple structure chart shown in 2 among Fig. 1;
Fig. 3 is the hack lever one package structual figure shown in 4 among Fig. 1;
