Description
Technical field
The invention belongs to technical field of civil engineering, relate to a kind of folding ladder。
Background technology
Folding ladder, is civil engineering articles for use, assist staff on-site high fall low, just like folding stair。The folding step used time opens, and is finished and amounts to, convenient transfer。Folded ladder requires that workmanship is necessary solid firmly, and folded ladder is widely used in various civil engineering, fitting-out work, and the compatibility that facilitates of folded ladder is liked by increasing people。
Folding ladder is as a kind of common equipment in a kind of field of civil engineering, it is possible to assist staff's operation to certain altitude on-site。Folding ladder launches when in use, and folding ladder can be amounted to after a procedure, convenient transport。Existing folding ladder both sides are also not provided with limiting fixing mechanism, cause that folding ladder is in use difficult to be adjusted exactly as required fixing, and existing folding ladder lower end is also not provided with anti-slipping mechanism, make folding ladder when the environmental work that some ground are relatively smooth, easily produce between folding ladder lower end and ground to slide, cause that folding ladder is difficult to firmly smoothly fix on the ground。
For this, application number be 201520462543.5 patent of invention disclose a kind of mobile folding ladder, it includes connecting plate, folding ladder and limiting fixing mechanism, limiting fixing mechanism is arranged between connecting plate and folding ladder, two folding ladders tilt to be symmetricly set on the both sides below connecting plate, folding ladder upper end and connecting plate are hinged, both sides, folding ladder lower end are respectively arranged with anti-skidding hold-down support, limiting fixing mechanism includes fixing sleeve, regulate screw mandrel, adjustable plate and adjustment sleeve, on the folding ladder that two pieces of adjustable plates are respectively provided at both sides, fixing sleeve is vertically arranged in connecting plate side, regulate sleeve hinge and be connected to adjustable plate one end, regulate screw mandrel to threaded through fixing sleeve with regulating sleeve straight down。This moves folding ladder according to using and needing of transporting regulates this and move folding ladder, and can ensure that this moves folding ladder in use firmly steadily, meets the needs of building house ornamentation。
Additionally, application number is the folding ladder that 201520310342.3 patents of invention also disclose that a kind of high stability, it includes two groups of foot of ladders, it is provided with main support rod between described two groups of foot of ladders, the top top board with bolts of described two groups of foot of ladders, being welded with stop collar on described top board, inside described foot of ladder, auxiliary with bolts supports, and described auxiliary supports and is flexibly connected secondary support bar with between foot of ladder by bolt。The folding ladder of this high stability when in use, improves the stability of folding ladder, it is to avoid the generation of situation toppled over by ladder when in use, improves end face platform area at ladder top top board simultaneously, meets Production requirement, and result of use is good。
But, all there is the safety issue of a common problem and folding ladder in above-mentioned folding ladder and existing folding ladder, it is all formed by front support stand and rear support stand are hinged due to folding ladder, after folding ladder is positioned on ground, when staff stands on folding ladder, two bracing frames of folding ladder are by stress, but under the effect of the frictional force bottom bracing frame and between ground, folding ladder not easily collapsed。The simple frictional force relied on bottom bracing frame and between ground prevents the rotation of the bracing frame safety to ensure the staff on folding ladder, the safety of this folding ladder is relatively low, very easily make the staff on folding ladder get off from folding ladder fading rise, cause the personal injury of staff。The anti-slipping mechanism that above-mentioned two sections of documents pass sequentially through anti-slipping mechanism that " regulate screw mandrel adjustable plate regulate sleeve " between two groups of foot of ladders form, " main support rod pair support bar auxiliary supports non-slipping block " forms realizes anti-skidding。But, realize anti-skidding by arranging anti-slipping mechanism between two groups of foot of ladders, and in the use procedure of folding ladder, staff need to shuttle between folding ladder, thus very easily the shuttling to cause and obstruct staff of the anti-slipping mechanism between foot of ladder, affect the efficiency of construction of staff；And owing to staff will often shuttle back and forth between two foot of ladders of folding ladder during operation, thus staff very easily collides on the anti-slipping mechanism between foot of ladder, causes the personal injury of staff。
Summary of the invention
It is an object of the invention to provide a kind of feed screw nut pair folding ladder, this folding ladder does not arrange anti-slipping mechanism between foot of ladder, staff can free shuttling between two foot of ladders, improve the work efficiency of staff, and the security performance of this folding ladder can be effectively improved, it is prevented that the personal injury that when staff shuttles back and forth between foot of ladder, staff is caused by some parts of folding ladder。
For achieving the above object, the technical scheme is that
