Abstract
The utility model belongs to ladders, and in particular relates to a straight ladder with good skid resistance. The straight ladder comprises two parallel straight ladder rods and a plurality of ladder sections which are arranged between the two parallel straight ladder rods in parallel, wherein an elastic non-skid block is arranged on the bottom end of each straight ladder rod; the supporting surfaces of the elastic non-skid blocks are arc, and sawtooth structures are formed on the arc supporting surfaces; and after the elastic non-skid blocks are sleeved on the bottom ends of the straight ladder rods, the bottom ends of the straight ladder rods are fixed through threaded rods. The elastic non-skid blocks are sleeved on the bottom ends of the straight ladder rods, so that the friction force between the ladder under the load-bearing condition and the supporting surfaces can be increased, and thus, the ladder has good skid resistance.
Description
Technical field
The utility model relates to a kind of ladder, specifically a kind of vertical ladder with good non-skid property.
Background technology
At present, the vertical ladder that building trade is used, general is all to adopt the two straight line ladder bars that be arranged in parallel and the parallel some section of ladders that are located between described two straight line ladder bars to form, the section of ladder of some vertical ladders also adopts D shape pipe as section of ladder, the terraced bar of this ladder generally adopts the flute profile material as terraced bar, directly is squeezed on the side of terraced bar by D shape is managed two ends, and the terraced bar of this ladder is owing to adopting the flute profile material to make, bearing is poor, and is not too firm; In addition, can make in use section of ladder produce relative sliding and then send friction noise in terraced bar junction and terraced bar, affect to a certain extent people's safe handling, can cause a kind of unsafe psychological impact to the people.In addition; at present, the vertical ladder that building trade is used is all generally to adopt the two straight line ladder bars that be arranged in parallel and the parallel some section of ladders that are located between described two straight line ladder bars to form; in order to prevent in use; ladder skids, and usually can be provided with limited slip piece in the bottom of terraced bar, but the sliding stop poor performance of present limited slip piece; particularly support ground etc. when more level and smooth; can cause the generation of skidding, easily cause security incident, have potential safety hazard.
The utility model content
The purpose of this utility model also is to provide a kind of vertical ladder with good non-skid property, be intended to solve the vertical ladder sliding stop poor performance of present building trade, particularly support ground etc. when more level and smooth, can cause the generation of skidding, easily cause security incident, have the problem of potential safety hazard.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is as follows:
A kind of vertical ladder with good non-skid property comprises the two straight line ladder bars that be arranged in parallel and the parallel some section of ladders that are located between described two straight lines ladder bars, and described straight line ladder bar bottom is provided with the elasticity limited slip block.
The supporting surface of described elasticity limited slip block is arc, is provided with broached-tooth design on described arc supporting surface.
Described elasticity limited slip block is sleeved on behind described straight line ladder bar bottom by screw rod and fix the terraced bar of described straight line bottom.
Be provided with pad at described section of ladder and junction, described straight line ladder bar inboard.
The two ends of described section of ladder link together by turnup structure and described straight line ladder bar.
Described straight line ladder bar is box section, and described section of ladder is D shape pipe.
Described straight line ladder bar and section of ladder are aluminum alloy material and make.
The utility model is by being provided with the elasticity limited slip block in described straight line ladder bar bottom, can strengthen ladder under load-bearing with the frictional force of supporting surface, thereby make the ladder non-skid property better.

In figure: 1, terraced bar, 2, section of ladder, 3, pad, 4, the elasticity limited slip block, 40, curved portions, 41, installing hole, 42, suit section, 43, broached-tooth design.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in Figure 1, the figure shows the structure of the vertical ladder with good non-skid property that the utility model embodiment provides.For convenience of explanation, only show the part relevant with the utility model embodiment.
A kind of vertical ladder with good non-skid property comprises the two straight line ladder bars 1 that be arranged in parallel and the parallel some section of ladders 2 that are located at 1, described two straight lines ladder bar, and described straight line ladder bar 1 bottom is provided with elasticity limited slip block 4.
More excellent, described elasticity limited slip block 4 is made by soft rubber material, or other soft material is made.
Described elasticity limited slip block 4 comprises a suit section 42 and the support portion 40 that is connected with described suit section 42, and the supporting surface of described support portion 40 is arc, is provided with broached-tooth design 43 on described arc supporting surface.
Described elasticity limited slip block 4 is sleeved on behind described straight line ladder bar 1 bottom by screw rod by suit section 42 and passes the fixing described straight line ladder bar of installing hole 41 2 bottoms that are located in described suit section 42.
Be provided with pad 3 in described section of ladder 2 and described straight line ladder bar 1 inboard junction.
Described straight line ladder bar 1 is box section, and described section of ladder 2 is D shape pipe.More excellent, described box section is rectangular tube.
The utility model is by being provided with the elasticity limited slip block in described straight line ladder bar bottom, can strengthen ladder under load-bearing with the frictional force of supporting surface, thereby make the ladder non-skid property better.
The utility model is by adopting box section as terraced bar, with D shape pipe as section of ladder, and be provided with pad at described section of ladder and junction, described straight line ladder bar inboard, in the function that has realized ladder, and make the load-bearing of ladder and steadiness good, make ladder more durable, and section of ladder can not occur in use and the friction noise that causes a kind of unsafe psychological impact to the people is sent in terraced bar junction because of slip.
More excellent, the cross sectional shape of the shape of described pad 3 and described section of ladder 2 adapts
More excellent, the two ends of described section of ladder 2 link together by turnup structure and described straight line ladder bar 1.
Because the two ends of described D shape pipe are connected by turnup structure and described straight line ladder bar, make connection more firm, and comparatively simple in manufacturing process, after directly the installing hole of the correspondence on described terraced bar being passed at the two ends of described D shape pipe, the D shape termination flange that will stretch out with instrument is pressed on described terraced bar lateral surface and gets final product.
Further, described straight line ladder bar 1 and section of ladder 2 are aluminum alloy material and make.Described pad 3 is made for aluminum alloy material.
The utility model has not only strengthened the steadiness of ladder, and has made ladder described in the utility model more light by adopting aluminum alloy material to make, and conveniently moves.
The above is only preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
