Abstract
The utility model relates to a buckle used for a folding boarding ladder. The buckle comprises a buckle body and clamping boards, wherein two ends of the buckle body are respectively provided one clamping board, the buckle body positioned between the two clamping boards is provided with an inwards concave arc surface, the inwards concave arc surface and the two clamping boards constitute an inwards concave arc-shaped bayonet, a T-shaped clamping slot is arranged in the central position at the other side of the buckle body opposite to the inwards concave arc-shaped bayonet, and the outer end of each clamping board is provided with a reinforcing assembly hole. The buckle disclosed by the utility model has the beneficial effects that two sides of the buckle body are respectively provided with the inwards concave arc-shaped bayonet and the T-shaped clamping slot, the processing cost is saved, the opened buckle is fixedly arranged on a stainless steel tube of the boarding ladder, the end of the T-shaped clamping slot is then butted with an additionally arranged fixing ring, the stainless steel tube of the boarding ladder can not be structurally destroyed, seawater can be prevented from entering the steel tube, the occupied space is saved, and the buckle has the advantages of reliable strength, better stability, easiness in assembly and the like.
Description
Technical field
The utility model relates to a kind of boarding ladder fastener, relates in particular to a kind of buckle for folding boarding ladder.
Background technology
Boarding ladder is generally used shipyard, harbour, passenger steamer and other engineering construction operating personnel, it is mainly the rectangular bar of steel structure boarding ladder that can vertically spiral up, for keeping stable floor area larger, if in the limited space of floor area, can be because unstability to a certain degree occurring highly too greatly and rocking, therefore, need to pack up after using or fold.For example, connect by buckle between every two joints of a lot of ship's ladders, not the used time, need folding being convenient to put; For the ship's ladder accident after folding is opened, need to use the opening buckle, the opening buckle is fixed in by screw on the stainless steel tube of ship's ladder, when shrinking ship's ladder, only needs the stainless steel tube of next joint ship's ladder is snapped in the opening that open card buckles.But this kind opening buckle needs screw to be fixed in the stainless steel tube of ship's ladder, has reduced the stainless steel tube fastness and has easily made seawater enter in stainless steel tube, easily produces corrosion phenomenon.Therefore, for above aspect, need to reasonably improve prior art.
Summary of the invention
For above defective, the utility model provide a kind of adopt large T slot structure, can be better for the two adjacent ship's ladder clampings of joint, stability, assembling easily, the buckle that is used for folding boarding ladder of position-adjustable, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of buckle for folding boarding ladder, comprise buckle main body and card adapter plate, buckle main body two ends arrange respectively a card adapter plate, an inner concave arc surface and this cambered surface and indent arc bayonet socket of two card adapter plates compositions are set on the buckle main body between two card adapter plates, the center position of the buckle main body opposite side relative with indent arc bayonet socket arranges a T shape draw-in groove, each card adapter plate outer end arranges one and reinforces assembly opening, and described buckle main center position arranges two overflow weirs.
The beneficial effect of the buckle for folding boarding ladder described in the utility model is: by the both sides in the buckle main body, an indent arc bayonet socket, a T shape draw-in groove are set respectively, be conducive to save tooling cost, this opening buckle is fixed on the stainless steel tube of ship's ladder, an end that is positioned at T shape draw-in groove docks with the mounting ring of additional configuration again, any structural destruction can not arranged the stainless steel tube of ship's ladder, can avoid seawater to enter steel pipe, be conducive to saving and take up room, have the advantages such as intensity is reliable, stability is better, assembling is easy.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of the described buckle for folding boarding ladder of the utility model embodiment.
In figure:
1, buckle main body; 2, card adapter plate; 3, indent arc bayonet socket; 4, reinforce assembly opening; 5, T shape draw-in groove; 6, overflow weir.
The specific embodiment
as shown in Figure 1, the described buckle for folding boarding ladder of the utility model embodiment, comprise buckle main body 1 and card adapter plate 2, described buckle main body 1 two ends arrange respectively a card adapter plate 2, an inner concave arc surface and this cambered surface and indent arc bayonet socket 3 of two card adapter plates 2 compositions are set on the buckle main body 1 between two card adapter plates 2, the buckle main body 1 opposite side center position relative with indent arc bayonet socket 3 arranges a T shape draw-in groove 5 and this T shape draw-in groove 5 and extends to buckle main body 1 inside, in addition, described buckle main body 1 center position arranges two overflow weirs 6, each card adapter plate 2 outer ends arrange one and reinforce assembly opening 4.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in protection domain of the present utility model.
