Utility model content
For problem above, this utility model provides a kind of portable extension type fire-fighting life-saving aerial ladder, simple for structure, carries with easy to use, and safety is high, less costly, is suitable for being arranged in the public arena such as school, hospital。
This utility model solves its technical problem and be the technical scheme is that a kind of portable extension type fire-fighting life-saving aerial ladder, including two expansion links and at least one cross bar, described cross bar is fixed between two expansion links by threeway connection, described expansion link includes the hook bar at the supporting seat of bottom, middle telescopic joint and top, the bottom of described telescopic joint is provided with Spring Card, the top of described telescopic joint is provided with fixing hole, the telescopic joint on upper strata slides up and down along the telescopic joint direction of principal axis of lower floor, and described hook bar is fixed with hook。
Described expansion link and cross bar are hollow-core construction。
Being provided with safety rope in described expansion link, safety rope two ends are fixed with hook bar and supporting seat respectively。
The cross bar being connected with supporting seat is provided with nylon tape, described nylon tape is provided with hidden discount。
It is connected by long spiral shell rivet is fixing between described hook bar with hook。
The beneficial effects of the utility model are:
1. simple for structure, carry with easy to use, adopt stretching structure, accept no time, simultaneously available nylon tape binding, and in use, nylon tape is opened, hook is tangled, it may be achieved launch, the bottom of telescopic joint is provided with Spring Card, the top of telescopic joint is provided with fixing hole, and upper and lower two telescopic joints are fixed by available Spring Card, and expansion link and cross bar are hollow-core construction, significantly reduce quality, carry with practical and convenient。
2. safety is high, connects by Spring Card is fixing, be provided with safety rope in simultaneous retractable bar between expansion link, and safety rope two ends are fixed with hook bar and supporting seat respectively, can play the effect of dual fail-safe。

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail。These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model。
As shown in Figure 1, 2, the portable extension type fire-fighting life-saving aerial ladder of one of the present utility model, including two expansion links 1 and at least one cross bar 2, described cross bar 2 is fixed between two expansion links 1 by threeway connection 3, described expansion link 1 includes the hook bar 6 at the supporting seat 4 of bottom, middle telescopic joint 5 and top, the bottom of described telescopic joint 5 is provided with Spring Card 7, the top of described telescopic joint 5 is provided with fixing hole 8, the telescopic joint 5 on upper strata slides up and down along telescopic joint 5 direction of principal axis of lower floor, and described hook bar 6 is fixed with hook 9。
Described expansion link 1 and cross bar 2 are hollow-core construction。
Being provided with safety rope 10 in described expansion link 1, safety rope 10 two ends are fixed with hook bar 6 and supporting seat 4 respectively。
The cross bar 2 being connected with supporting seat 4 is provided with nylon tape 11, described nylon tape 11 is provided with hidden discount 12。
It is connected by long spiral shell rivet 13 is fixing between described hook bar 6 with hook 9。
The portable extension type fire-fighting life-saving aerial ladder of one of the present utility model, adopts stretching structure, accepts no time, available nylon tape 11 bundlees simultaneously, and in use, is opened by nylon tape 11, hook 9 is tangled, can realizing launching, the bottom of telescopic joint 5 is provided with Spring Card 7, and the top of telescopic joint 5 is provided with fixing hole 8, upper and lower two telescopic joints 5 are fixed by available Spring Card 7, expansion link 1 and cross bar 2 are hollow-core construction, significantly reduce quality, carry with practical and convenient。Safety is high, connects by Spring Card 7 is fixing, be provided with safety rope 10 in simultaneous retractable bar 1 between expansion link 1, and safety rope 10 two ends are fixed with hook bar 6 and supporting seat 4 respectively, can play the effect of dual fail-safe。
