Abstract
The utility model belongs to field of furniture, relates to bunk beds ladder, especially a kind of bunk beds extension ladder.Bunk beds extension ladder is made up of bedstead, slide rail storehouse, extension ladder three part, and it is characterized in that, extension ladder is made up of ladder, rotating shaft, pedal and retaining mechanism, and ladder is different-diameter steel pipe nested structure, can Tension and Compression; Pedal is wooden wide plate structure, and trampling mask has anti-slip veins, and when extension ladder shrinks, pedal and ladder are positioned at the same face, and during extension ladder expansion, pedal can form special angle by rotating shaft and ladder and fixes.Extension ladder can advance in slide rail storehouse after shrinking, and saves space, and increases the activity space of lower berth personnel.This bunk beds structure of telescopic ladder is simple, easy to install, and space availability ratio is high, is applicable to the dormitory that activity space is less.
Description
Technical field
The utility model belongs to field of furniture, relates to bunk beds ladder, especially a kind of bunk beds extension ladder.
Background technology
Berth many employings bunk beds in school, factory dormitory, to improve the utilization rate in dormitory space.The ladder that general bunk beds are equipped with is steel work ladder, and ladder crossbeam is square tube or circular tube structure, crossbeam of stepping on when upper berth personnel go to bed, and because lifting surface area is little, pin can feel uncomfortable especially.Double-deck bed steps are welded on bunk beds side, and in straight up and down state, this vertical stratification especially easily causes security incident when sole skids, while be fixed on a side due to double-deck bed steps, affect the activity space of lower berth personnel.
Application number is the utility model patent of CN201420034991.0, disclose a kind of electric expansion stair of Armrest, comprise motor, winding belt wheel, wire rope, Compress Spring, broadstep, collapsible riser and handrail guardrail, under these flexible stair are applicable to interior space of residence limited situation, can by stair folded concealed on loft top when not using, can Automatic-expanding when needing, facilitate personnel upper and lower.
Above-mentioned flexible stair volume is comparatively large, and be applicable between domestic floor, structure is comparatively complicated, installs and fixedly takes up room comparatively greatly, be used in bunk beds and have limitation, and cost is higher, is not easy to promote.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of bunk beds extension ladder, compresses in slide rail when not using, and can launch to use during use, and save space, pedal adopts wooden wide plate, use safety, convenience.
The technical solution of the utility model is as follows:
Bunk beds extension ladder, comprises bedstead, slide rail storehouse, extension ladder three part.Extension ladder is made up of ladder, rotating shaft, pedal and retaining mechanism, and ladder is different-diameter steel pipe nested structure, can stretch and shrink, and pedal adopts wooden wide plate structure, and the face of trampling is designed with anti-slip veins; Slide rail is positioned at bed board bottom surface, upper strata, after extension ladder shrinks, advance slide rail storehouse inner by sliding track mechanism; When extension ladder shrinks, ladder and pedal are positioned at same plane, can promote comprehensively in slide rail storehouse, and when extension ladder launches to use, pedal forms a fixed angle by rotating shaft rotation and ladder, and is fixed by retaining mechanism, convenient, safety.
Effect of the present invention and benefit are this bunk beds extension ladder pedals is wooden wide plate, tramples conveniently, comfortable during bunk bed; Extension ladder is trailed when using, and advances slide rail storehouse after shrinking when not using, and saves space, and increases the activity space of lower berth personnel.This bunk beds structure of telescopic ladder is simple, easy to install, and space availability ratio is high, is applicable to the dormitory that activity space is less.

In figure: 1 bedstead; 2 slide rail storehouses; 3 telescopic ladders; 4 rotating shafts; 5 ladders; 6 pedals.
Detailed description of the invention
Concrete case study on implementation of the present utility model is described in detail below in conjunction with technical scheme and accompanying drawing.
Bedstead 1 is divided into upper and lower bed, and slide rail storehouse 2 is positioned at upper strata bed board basal surface position, and after bunk beds extension ladder shrinks, structure is telescopic ladder 3, and telescopic ladder 3 can directly advance in slide rail storehouse 2 by slide rail; Ladder 5 structure is that different-diameter steel pipe nests together, and expansion sleeve pipe stretches out, and during contraction, sleeved compression together; Pedal 6 is wooden wide plate, and trampling mask has anti-slip veins, and it is by rotating shaft 4, and be fixed in the steel pipe of ladder 5, pedal 6 can rotate around rotating shaft 4, forms special angle with ladder 5.
When extension ladder launches to use, the sleeve structure in ladder 5 stretches out, and pedal 6 rotates special angle around rotating shaft 4, and is fixed by retaining mechanism, now can climb up upper berth by foot pedal 6; When not using extension ladder, together, and pedal 6 rotates as in the same plane of ladder 5 the sleeve pipe compact compression in ladder 5, forms telescopic ladder 3, and is advanced in slide rail storehouse 2 by slide rail.
