Description
Technical field
The utility model relates to a kind of ladder antiskid pedal.
Background technology
Existing ladder comprises two columns and at least one antiskid pedal that is located between two columns.This antiskid pedal is divided into two classes, and a class is that injection moulding is made, and another kind of is that metal is made.No matter be that injection moulding is made or metal antiskid pedal, its end face all is the plane in early days, and the non-skid property on plane is poor, so security performance is not high.At above-mentioned deficiency, the someone has proposed a solution, skid-proof point is set or the antiskid pedal end face is arranged to waveform at the antiskid pedal end face exactly, to improve friction factor.Though the skidproof effect of this solution is better than smooth flat, it is best that skidproof effect does not also reach, and also has potential safety hazard.
The utility model content
The utility model provides a kind of ladder antiskid pedal, and it has overcome the not good deficiency of the existing skidproof effect of stair treads of background technology.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of ladder antiskid pedal, this ladder comprises two columns and at least one antiskid pedal that is located between two columns, this antiskid pedal comprises a matrix, this matrix has a panel, this panel end face is provided with many detents, offers at least one through hole that runs through at the bottom of the panel top on this detent bottom surface, all is provided with an adaptive reeding on this each detent, this reeding bottom surface convexes with at least one back-off, those back-offs and the corresponding one by one snapping that also assembles mutually of those through holes.
In the preferred embodiment of the present utility model, parallel, the even interval of those detents is provided with.
In the preferred embodiment of the present utility model, those detents are parallel to the median surface by two column axis location.
In the preferred embodiment of the present utility model, this back-off has once affixed section of being fixed in the reeding bottom surface, is arranged on and inserts section and the interlude between affixed section once the terminal section and of inserting for taper, this interlude diameter is less than the through hole diameter, and this just inserts the section maximum gauge greater than the through hole diameter.
In the preferred embodiment of the present utility model, it is slotting section taper, affixed interlude that this back-off has once an interlude that is fixed in the reeding bottom surface and an end, and this interlude diameter is less than the through hole diameter, and this just inserts section maximum gauge greater than the through hole diameter.
In the preferred embodiment of the present utility model, this reeding thickness is greater than the detent degree of depth, and, this reeding end face projecting surface plate top surface.
In the preferred embodiment of the present utility model, this matrix also comprises carriage and reinforcing rib, and this panel is fixed on the carriage, and this reinforcing rib connects carriage and support panel.
In the preferred embodiment of the present utility model, the material of this reeding is plastics; The material of this matrix is an aluminium alloys.
The technical program is compared with background technology: 1, this antiskid pedal is provided with reeding, and it can improve the skidproof effect of antiskid pedal, the security performance height.2, this reeding is arranged within the detent, and cooperates the assembling of through hole and back-off, is connected firmly, and is easy to assembly quick.3, this reeding can prevent, reduce the antiskid pedal wearing and tearing, and (antiskid pedal generally passes through surfacing, for example takes to dust, measure such as zinc-plated grade, some surfacing is worn and torn easily by scratch), reason is that reeding can reduce contacting of user's sole and antiskid pedal face.4, this reeding can play certain booster action to antiskid pedal.5, this reeding can increase the aesthetic property of antiskid pedal, antiskid pedal is taken a fancy to be full of variety.6, the parallel median surface of those detents by two column axis location, parallel, even interval is provided with, anti-skidding targetedly, security performance height (because user's sole generally is vertical antiskid pedal plane, so the direction setting of this reeding is can specific aim anti-skidding).7, just inserting section terminal is taper, is convenient to assemble snapping.8, this interlude diameter is less than the through hole diameter, and this just inserts the section maximum gauge greater than the through hole diameter, firmly snapping.9, this reeding end face projecting surface plate top surface, good antiskid effect can be prevented the antiskid pedal wearing and tearing.10, this panel is fixed on the carriage, and this reinforcing rib connects carriage and support panel, the supported intensity height of panel, and carriage can be convenient to connect outside component.

Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 has illustrated the schematic perspective view of the ladder of a preferred embodiment.
Fig. 2 has illustrated the perspective exploded view of the antiskid pedal of a preferred embodiment.
Fig. 3 has illustrated the schematic perspective view of the reeding of a preferred embodiment.
Fig. 4 has illustrated the vertical view of the antiskid pedal of a preferred embodiment.
Fig. 5 has illustrated the A-A generalized section of Fig. 4.
The specific embodiment
Please refer to Fig. 1, this ladder is a folded ladder, and it comprises that two front columns 100, two rear columns and are located at the antiskid pedal 200 between two columns 100.
Please refer to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, this antiskid pedal 200 comprises a matrix and many reedings that are made of plastics 240 of being made by aluminium alloys.
This matrix has carriage 210, a panel 220 and the reinforcing rib 230 of a rectangle, and this panel 220 is fixed on the carriage 210 also one-body molded, and this reinforcing rib 230 connects carriages 210 and support panels 220.These panel 220 end faces are provided with the detent 221 that equates with 240 numbers of reeding.Those detent 221 parallel, even intervals are provided with, and they also are parallel to the median surface by two columns, 100 axis location.Offer a plurality of panel 220 top through holes 222 at the end that run through on these detent 221 bottom surfaces.
These reeding 240 bottom surfaces convex with the back-off 241 with numbers such as through holes 222.This back-off 241 has once affixed section of being fixed in reeding 240 bottom surfaces, is arranged on and inserts section and the interlude between affixed section once the terminal section and of inserting for taper, this interlude diameter is less than through hole 222 diameters, this just inserts the section maximum gauge greater than through hole 222 diameters, and minimum diameter is less than through hole 222 diameters.
Those reedings 240 and those detents 221 are adaptive one by one, and wherein: those reedings 240 are separately positioned on corresponding detent 221; Those back-offs 241 are corresponding one by one with those through holes 222 and assemble snapping mutually, and this annular step tread of just inserting section abuts against panel 220 bottom surfaces.
These above-mentioned reeding 240 thickness are greater than detent 221 degree of depth, so these reeding 240 end faces protrude panel 220 end faces.
In another preferred embodiment, it and a last preferred embodiment difference are: it is slotting section taper, affixed interlude that this back-off has once an interlude that is fixed in the reeding bottom surface and an end, this interlude diameter is less than the through hole diameter, and this just inserts the section maximum gauge greater than the through hole diameter.
In another preferred embodiment, it and a last preferred embodiment difference are: this matrix is made by injection moulding.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
