Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-5, a connection structure is prevented rocking by telescopic ladder, including ladder chassis 1 and bracing piece 2, the bottom of ladder chassis 1 is provided with sill bar 10, and blind hole 11 has all been seted up to the both sides of sill bar 10, is provided with fixed block 16 between two blind hole 11, and bracing piece 2 slidable mounting is in blind hole 11, and bracing piece 2 keeps away from one end fixedly connected with collateral branch fagging 20 of fixed block 16.

The working principle is as follows: all be provided with bracing piece 2 in the both sides of sill bar 10, when the extension ladder need rise, it is rotatory to drive bracing piece 2 through rotatory side support board 20, when slider 21 matches with spout 13, spring 14 can outwards pop out bracing piece 2, and the one end of bracing piece 2 can stop one section length in sill bar 10, when the extension ladder risees, support the extension ladder through two bracing pieces 2 and two slider 21, the stability of extension ladder has been improved, when the extension ladder is packed up, inwards promote bracing piece 2 through anti-skidding tooth's socket 201, when one side laminating of anti-skidding tooth's socket 201 and ladder chassis 1, rotatory anti-skidding tooth's socket 201, slider 21 can block in rotatory inslot 12 this moment, avoid bracing piece 2 outwards to pop out.
