Description

Portable ladder

Technical field

The utility model relates to a kind of Portable ladder.

Background technology

At present, in power industry, construct or often need to climb during line upkeep, because the height of climbing is different at every turn, particularly during operation in the wild, ladder carries inconvenience, general carrying foldable ladder all, this ladder is easy to carry, but after launching, insufficient height is high, and many times staff uses this ladder still can not get at operating surface, this just need to separately think the way of padded ladder, has had a strong impact on operating efficiency.

Utility model content

The utility model, in order to solve weak point of the prior art, provides a kind of height adjustable Portable ladder.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: Portable ladder, comprise the identical short ladder of at least two joints, the short ladder of every joint includes two parallel longerons and is located at two pedals between longeron, the short ladder of adjacent two joint removably connects by connector, described connector comprises two sleeve pipes that be arranged in parallel, between two sleeve pipes, be vertically provided with at least one connecting rod, corresponding inserted is two sleeve pipe one end respectively for two longerons of the short ladder of one joint, and another saves two longerons difference corresponding inserted of short ladder at the other end of two sleeve pipes.

Longeron one inner side, end of described short ladder is provided with for hanging the hook of kit bag; Longeron and pedal adopt steel pipe, and longeron and pedal appearance are enclosed with insulation rubber.

Adopt technique scheme, if operation height is lower, can use the independent short ladder of a joint, if operation height is higher, just the longeron of the short ladder of two joints is inserted into respectively to the two ends of sleeve pipe, two short ladders are connected together to use, if operation height is high again, just uses connector to connect short ladders more than three joints and use.

The utility model is reasonable in design, simple in structure, be convenient to dismounting and carry, and can according to actual conditions, lengthen or shorten the length of ladder, practical, easy to utilize.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, Portable ladder of the present utility model, comprise the identical short ladder (ladder that length is shorter) of at least two joints, the short ladder of every joint includes two parallel longerons 1 and is located at two pedals 2 between longeron 1, the short ladder of adjacent two joint removably connects by connector, described connector comprises two sleeve pipes that be arranged in parallel 3, between two sleeve pipes 3, be vertically provided with at least one connecting rod 4, corresponding inserted is two sleeve pipe 3 one end respectively for two longerons 1 of the short ladder of one joint, and another saves two longerons, the 1 difference corresponding inserted of short ladder at the other end of two sleeve pipes 3.Longeron 1 one inner sides, end of short ladder are provided with for hanging the hook 5 of kit bag.Longeron 1 and pedal 2 can adopt bamboo pole or steel pipe, and while adopting steel pipe, appearance needs wrap insulate rubber, more safe and reliable when carrying out operation like this.

When the utility model is used in work, if operation height is lower, can use the independent short ladder of a joint, if operation height is higher, just the longeron 1 of the short ladder of two joints is inserted into respectively to the two ends of sleeve pipe 3, two short ladders are connected together to use, connecting rod 4 is just in time as foot-operated, if operation height is high again, just uses connector to connect short ladders more than three joints and use.

Claims (1)

1. Portable ladder, comprise the identical short ladder of at least two joints, the short ladder of every joint includes two parallel longerons and is located at two pedals between longeron, it is characterized in that: the short ladder of adjacent two joint removably connects by connector, described connector comprises two sleeve pipes that be arranged in parallel, between two sleeve pipes, be vertically provided with at least one connecting rod, corresponding inserted is two sleeve pipe one end respectively for two longerons of the short ladder of a joint, and another saves two longerons difference corresponding inserted of short ladder at the other end of two sleeve pipes;

Longeron one inner side, end of described short ladder is provided with for hanging the hook of kit bag; Longeron and pedal adopt steel pipe, and longeron and pedal appearance are enclosed with insulation rubber.
