Description
Technical field
The utility model relates to a kind of stair, and specifically a kind of portable folding stair, belong to building implements field.Be particularly suitable for the use of setting up of building site, open stage.
Background technology
As everyone knows, stair make and the process of transportation in suitable troubles all, and the recycle value of stair is very low on-site, is all generally disposable.Along with setting up of the social current open stage of progress is also more and more, common stair have brought very large inconvenience to the transportation of stage shelf, and the first volume is too large, and the second weight is excessive.Long-term carrying also can cause the distortion of stair, has shortened greatly the life-span of stair, is virtually increasing cost of manufacture.
Summary of the invention
In order to address the above problem, the utility model provides a kind of portable folding stair.
The utility model is achieved by the following technical solution: a kind of portable folding stair, comprise support and detachable rack-mount marking time; Described support comprises bracket upright post, column top rail, column lower transverse beam, oblique column, oblique column lower transverse beam and lower transverse beam connection cord; The upper end of bracket upright post is hinged with the upper end of oblique column; Described column top rail is connected between the top of two bracket upright post, and column lower transverse beam is connected between the bottom of two bracket upright post; The two ends of described oblique column lower transverse beam are connected with the bottom of two oblique columns respectively; Described lower transverse beam connection cord is tightrope, and two lower transverse beam connection cords divide left and right to be connected between column lower transverse beam and oblique column lower transverse beam; Described marking time comprises step plate and the fagging of marking time; Step plate and marking time is articulated and connected between fagging, step plate rear portion with tiltedly between column, adopt latch to be connected.
During use, bracket upright post is vertically stood on ground, pulled open oblique column, then step plate is launched, make it to be horizontal, launch to mark time fagging, make it, in vertically standing on ground, to plug latch.In the time of need to moving, just can stair are folding mobile according to above-mentioned contrary order.
The beneficial effects of the utility model are that stair launch easily, easy to carry.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, foldable stair support; 1.1, bracket upright post; 1.2, column top rail; 1.3, column lower transverse beam; 1.4, oblique column; 1.5, oblique column lower transverse beam; 1.6, lower transverse beam connection cord; 2, mark time; 2.1, step plate; 2.2, the fagging of marking time.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model structure is further illustrated.
As shown in Figure 1, portable folding stair are by support 1 be detachably arranged on and mark time 2 on support 1; Support 1 is comprised of bracket upright post 1.1, column top rail 1.2, column lower transverse beam 1.3, oblique column 1.4, oblique column lower transverse beam 1.5 and lower transverse beam connection cord 1.6; The upper end of bracket upright post 1.1 is hinged with the upper end of oblique column 1.4; Column top rail 1.2 is connected between the top of two bracket upright post 1.1, and column lower transverse beam 1.3 is connected between the bottom of two bracket upright post 1.1; Tiltedly the two ends of column lower transverse beam 1.5 are connected with the bottom of two oblique columns 1.4 respectively; Lower transverse beam connection cord 1.6 is tightrope, can fold; Two lower transverse beam connection cords are connected to column lower transverse beam 1.3 and oblique 1.5 of column lower transverse beams about 1.6 minutes.Described marking time 2 comprises step plate 2.1 and the fagging 2.2 of marking time; Step plate 2.1 and marking time is articulated and connected between fagging 2.2, step plate 2.1 rear portions with tiltedly between column 1.4, adopt latch to be connected.
The steel pipe of 38 millimeters of the support 1 use diameters of the present embodiment is made, and also can make with 45 bugle steel, also can be with the imitative wooden one-tenth of 50 * 80 millimeters; Between bracket upright post 1.1 and tiltedly column 1.4 with hinged; Between bracket upright post and column top rail, column lower transverse beam, adopt and be welded to connect; Tiltedly between column and oblique column lower transverse beam, adopt and be welded to connect; Between lower transverse beam connection cord 1.6 and column lower transverse beam 1.3 and oblique column lower transverse beam 1.5, be welded to connect.
If while adopting imitated wood material to make, between bracket upright post 1.1 and column top rail, column lower transverse beam 1.3, adopt joggle to be connected; The oblique column of support with tiltedly between column lower transverse beam, adopt joggle to be connected; Between lower transverse beam connection cord 1.6 and column lower transverse beam 1.3 and oblique column lower transverse beam 1.5, be articulated and connected; Also can be fixedly connected with by other method.
Described marking time made of 2-3 millimeters thick steel plate, also can make of 4-6 millimeter aluminium alloy plate, can also make of 20-40 millimeters thick plank; Step plate front portion and the employing between fagging of marking time are articulated and connected, and rear portion adopts latches to be connected with oblique column 1.4.
During use, first according to shown in Fig. 1, launch,
During use, first according to stent shown in Fig. 11, make the position of bracket upright post 1.1 in vertical ground, launch oblique column 1.4, then launch step plate, make it to be horizontal, the expansion fagging of marking time, makes it in vertical position, plugs latch and prevents step plate play.
In the time of need to moving, just can stair are folding mobile according to above-mentioned contrary order.Not the used time, can fold and pack up.
