Abstract
A kind of outer ladder section of extension ladder, it is characterised in that：With a profiled body, the cross section of the profiled body includes top plate and is connected with the sidewall paneling of top plate both sides, has the opening opened downwards；Formed with bevel edge is strengthened, which, which has, thickens structure for the junction of top plate and sidewall paneling；The outer surface for strengthening bevel edge is equipped with a plurality of anti-skidding damping striped；The inner surface of sidewall paneling is recessed with escape groove.Compared to existing technologies, setting of the utility model by strengthening bevel edge not only improves the structural strength of section bar in itself, and improves skid resistance when extension ladder uses, and the compactedness that rear cleat stanchion is combined with interior ladder section is improved by the setting of escape groove.To sum up, the utility model has the advantages that reasonable in design, intensity is high, skid resistance is good.
Description
Technical field
It the utility model is related to a kind of section bar, and in particular to a kind of outer ladder section of extension ladder.
Background technology
Ladder, is the common tool climbed to a higher point.It is more typical for vertical ladder and double ladder in ladder.In most cases, ladder
It can meet the needs of climbing to a higher point of user, but in some cases, such as when the height that user needs to climb to a higher point exceedes the pole of ladder
In limited time, ladder can not just meet the requirement climbed to a higher point at this time.
In order to solve the problems, such as this, industry has invented a kind of extension ladder, as shown in Figure 1, the cleat stanchion 1 of the extension ladder is equipped with
Telescopic device 2, the cleat stanchion 1 include the outer ladder section 4 of interior ladder section 3 and sliding sleeve outside the interior ladder section 3（See figure
2）；Telescopic device 2 is fixedly arranged in the outer ladder section 4, and one group of locating slot in relatively described interior ladder section 3 is set, each fixed
Position groove is placed equidistant with along the length direction of cleat stanchion 1；By unlock of the telescopic device 2 to different height position locating slot and locking come
The position relationship between the interior ladder section 3 and the outer ladder section 4 is adjusted, so as to achieve the purpose that adjusting cleat stanchion 1 stretches.
The above-mentioned problems of the prior art is：The structure design of the outer ladder section 4 is embodied there are certain defect
Structural strength it is not good enough, with manhole ladder on mark time riveting point 5 exist interfere the problem of；And interior 3 both sides of ladder section in the prior art
Riveting point 5 of marking time due to the inner surface directly against outer ladder section 4, i.e., both are point contacts, therefore also there are interior ladder type
Material 3 is connected not compact, easy the problem of rocking with outer ladder section 4.
Therefore, above-mentioned many deficiencies existing in the prior art how are solved, are become as the class to be studied of the utility model
Topic.
The content of the invention
The purpose of this utility model is to provide a kind of outer ladder section of extension ladder.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：
A kind of outer ladder section of extension ladder, including a profiled body, the cross section of the profiled body are horizontally disposed with by one
Top plate and being connected with respectively formed in the both sides of the top plate and the sidewall paneling that extends downwardly so that the profiled body has one
The opening opened downwards；
Wherein, bevel edge is strengthened in the junction of the top plate and each sidewall paneling formed with one, and the reinforcement bevel edge is at least
A part has one to thicken structure, which is more than the thickness of the top plate and the thickness of each sidewall paneling
Degree；
Wherein, a plurality of anti-skidding damping striped being arranged in parallel is additionally provided with the outer surface for strengthening bevel edge, and it is each described
Anti-skidding damping striped is set along the length direction of the profiled body；
Wherein, one escape groove of recessed formation, the escape groove correspond to extension ladder manhole ladder on the inner surface of each sidewall paneling
On mark time riveting point setting.
Related content in above-mentioned technical proposal is explained as follows：
1. in such scheme, by the design for thickening structure, the structural strength of profiled body is added, and then lifted
The security of extension ladder.
2. in such scheme, the anti-skidding damping striped is to lift skid resistance when extension ladder uses, to ensure personnel
Safety, while improve the aesthetics of extension ladder.
3. in such scheme, the design of the escape groove, the riveting point marked time available for avoidance, therefore interior ladder section appearance
Face will can carry out part with the inner surface of outer ladder section and be bonded, and with the compactedness of both combinations of lifting, avoid producing during use
Rock.
Therefore interior ladder section and outer ladder section will change the prior art and pass through riveting point；
The operation principle and advantage of the utility model are as follows：
A kind of outer ladder section of extension ladder of the utility model, the cross section of its profiled body include top plate and are connected with top plate
The sidewall paneling of both sides, has the opening opened downwards；The junction of top plate and sidewall paneling is formed with reinforcement bevel edge, the reinforcement bevel edge
With thickening structure；The outer surface for strengthening bevel edge is equipped with a plurality of anti-skidding damping striped；The inner surface of sidewall paneling is recessed with escape groove.
Compared to existing technologies, setting of the utility model by strengthening bevel edge not only improves the structural strength of section bar in itself, and
And skid resistance when extension ladder uses is improved, and improved by the setting of escape groove and combined the tight of rear cleat stanchion with interior ladder section
Gathering property.To sum up, the utility model has the advantages that reasonable in design, intensity is high, skid resistance is good.
