Abstract
The utility model relates to a stair tripod with a locating flange, which belongs to the manufacturing field of a hand ladder. During the process of storage and transportation, the prior hand ladder stairs cannot be piled by means of the self-structure. The stair tripod comprises a stand body of the tripod, wherein, the middle part of the stand body is provided with a triangular hollow part; the circumference of the stand body and the hollow part are provided with a plurality of turned-over edges in the same direction. The stair tripod is characterized in that an extended locating flange is arranged on the turned-over edge at the lower front side of the stand body. The stair tripod has the advantages that: through the locating flange additionally arranged on the turned-over edge of the tripod, the stairs can be piled by means of the self-structure with compact piled volume, and transportation cost is saved; at the same time, a beam connection part is provided so as to lighten the weight of the stairs.
Description
[technical field]
The utility model relates to a kind of structure improved step spider, particularly with the step spider of locating flange, belongs to stair step and makes the field.
[background technology]
The step spider is used for connecting and sustain pedal assembly, kickplate assembly, crossbeam and main wheel axle bed, jockey pulley, is the important composition parts of stair step; Usually made by the sheet metal backfin, support body is roughly triangular in shape, and the middle part has the triangle hollow bulb, and the week of support body and hollow bulb is along being become flange by backfin.Existing stair step is in storage and transport process, can't rely on self structure to stack, need between the step that two joints are put in opposite directions, place the plastics shelf, in order to fix main wheel axle bed, the jockey pulley axle of two joint steps, prevent the mutual collision deformation of step, avoid damaging in the storage and transport process.If transportation step in enormous quantities just needs a considerable number of plastics shelf, not only make the unit packaging increase in volume, and plastics shelf intensity difference, fragile, thereby cause traffic cost high.In case the plastics shelf damages, and can make the step that stacks collapse, damage.In addition, in the prior art, also on the flange at spider top, weld and be used for and pedal assembly, crossbeam bonded assembly strap stiffener, and welded nut thereon, increasing the consumption raw MAT'L, manufacturing procedure is loaded down with trivial details.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is the defective that overcomes existing step spider, and a kind of step spider that makes step rely on that self structure stacks, intensity is good and be with locating flange is provided.For this reason, the utility model adopts following technical scheme:
The step spider of band locating flange comprises leg-of-mutton support body, and the support body middle part has the triangle hollow bulb, and the periphery of described support body and hollow bulb is provided with flange in the same way, it is characterized in that: the inferoanterior flange of described support body is provided with the locating flange of abduction.When two steps stack in opposite directions, the jockey pulley of one joint step is relative with the main wheel axle bed of another joint step, outwards be bent with integrated locating flange on the spider support body inferoanterior flange, in order to clamping, fixing cooresponding jockey pulley, thereby realize that step relies on self structure to stack, omit existing shelf, stack volume compact, save traffic cost.
For the improving and replenishing of technique scheme, can increase following technical characterictic:
Described locating flange comprises prelocalization limit and back edge, and prelocalization limit, back edge all are the L type and outwards bend perpendicular to the flange at its place, and prelocalization limit, back edge and flange between the two surround jockey pulley seat accommodation section.When two joint steps stack in opposite directions, the jockey pulley seat of one joint step just cooperates with the jockey pulley seat accommodation section of another step, the jockey pulley seat of top step just is stuck on the prelocalization limit of below step, can not glide, prelocalization margin system two joint steps moving on front and back and above-below direction; Back edge is used for the flange clamping with another step jockey pulley seat place, thus limit two the joint steps left and right directions on relative displacement.
The flange extension on described support body top is provided with the crossbeam connecting portion.Such structure can be omitted strap stiffener when connecting what crossbeam of pedal assembly, when satisfying intensity, alleviate the weight of step.
Have mounting hole on the described crossbeam connecting portion, be welded with nut on the crossbeam connecting portion medial surface at mounting hole place.Be convenient to the Fast Installation pedal assembly.
The utility model has realized that by the locating flange of one is set step relies on self structure to stack on the flange of spider, stack volume compact, saves traffic cost, and the crossbeam connecting portion is set simultaneously, can alleviate the weight of step.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, prelocalization limit, 2, the back edge, 3, the crossbeam connecting portion, 4, hollow bulb, 5, flange, 6, jockey pulley seat accommodation section.
[specific implementation]
Below in conjunction with specification drawings and specific embodiments substantive distinguishing features of the present utility model is further described.
As shown in Figure 1, the step spider of band locating flange can adopt stainless steel sheet to be stamped to form, comprise leg-of-mutton support body, the support body middle part has triangle hollow bulb 4, and the periphery of support body and hollow bulb is provided with flange 5 in the same way, and the inferoanterior flange 5 of support body is provided with the locating flange of abduction.Locating flange comprises prelocalization limit 1 and back edge 2, and prelocalization limit 1, back edge 2 all are the L type and outwards bend perpendicular to the flange at its place, and prelocalization limit 1, back edge 2 and flange between the two surround jockey pulley seat accommodation section 6.Prelocalization limit 1 back edge 2 is slightly long.The flange extension on support body top is provided with crossbeam connecting portion 3.Have mounting hole on the crossbeam connecting portion 3, be welded with nut on the crossbeam connecting portion medial surface at mounting hole place.Support body front portion and bottom have mounting hole, are used to connect main wheel axle bed, jockey pulley seat and jockey pulley.
When step stacks, two joint step main wheel axle beds are relative with jockey pulley, the jockey pulley axle of one joint step places another step prelocalization limit 1, back edge 2 and flange between the two to surround jockey pulley seat accommodation section 6, the jockey pulley glides downward has been limited on prelocalization limit 1, has prevented that two joint steps from reaching the relative displacement of fore-and-aft direction up and down.Back edge 2 is used for the flange clamping with another step jockey pulley seat place, has limited the relative displacement of two joint step left and right directions.Thereby make step in storage and transport process, do not need to rely on the plastics shelf, only rely on stacking that self structure can be safe, obviously reduced the damage that causes because of collapsing in the storage and transport process.
