As a kind of improvement, described each terraced body is slidingly connected successively by the sliding sleeve that is arranged on the pole respectively.
As further improvement, describedly be positioned at that extension ladder is rotating respectively on the pole of each terraced body of terraced body downside topmost to be provided with mousing-hook.
As further improvement, be provided with the spring that can promote mousing-hook between described mousing-hook and the pole.
As further improvement, described fixed part comprises the stay hook that is separately positioned on two pole inboards.
As further improvement, described stay hook and pole are articulated and connected, and are provided with connecting rod between described two stay hooks.
As further improvement, be positioned at described extension ladder and be connected with drag hook by rope in the top of terraced body topmost.
As further improvement, described stull is in-line.
As further improvement, described improved safety extension ladder also comprises the protection rope.
As further improvement, be arranged in order respectively on the described pole and be provided with some jacks, the pole top that is positioned at the terraced body of bottom in described each adjacent terraced body is respectively equipped with latch.
Owing to adopted improved safety extension ladder of said structure; by some by between two poles, being provided with the terraced body that some stulls constitute; each terraced body is slidingly connected successively mutually; be respectively equipped with the block that to control each terraced body slide displacement at the pole two ends; be provided with the fixedly fixed part of extension ladder on the top that is positioned at the terraced body in extension ladder the top; and the lower end of each terraced body is respectively equipped with and can makes extension ladder leave the supporter of ladder attachment; the supporter that is provided with by each terraced body promotes the surface that extension ladder leaves the attachment such as the wall that are used to hang ladder like this; hold pin when having increased the climbing of user's ladder greatly and stepping on the position area, protected the safety of using.And the fixed part that the terraced body by extension ladder upper end is provided with, people just can be fixed in the extension ladder suspension easily and be carried out hanging operation on windowsill or other fixture, and the shaking phenomenon of rope ladder can not occur, have ensured user's personal safety.Adopt the fixedly fixed part of hook-type, can easily the extension ladder hook be held on windowsill or other object, strengthened the security performance when using.And by being provided with the mousing-hook that promotes spring, can not use and when packing up, each terraced body is hooked at extension ladder, prevent to throw off each other, be convenient to storing; By on pole, being respectively equipped with jack, and be provided with the frame mode of latch, actual conditions that can be when using extension ladder, the length of regulating extension ladder easily the pole of adjacent terraced body.Top rope by the terraced body in extension ladder the top is connected with drag hook, the security performance in the time of can further increasing the extension ladder use.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Accompanying drawing is the structural representation of improved safety extension ladder of the utility model.
The specific embodiment
As shown in drawings, improved safety extension ladder, comprise some by between two poles 11, being provided with the terraced body 1 that some stulls 12 constitute, each terraced body 1 is slidingly connected successively mutually, it can adopt the pole 11 at each terraced body 1 to be respectively equipped with sliding sleeve 4, each terraced body 1 was slidingly connected by sliding sleeve 4 and cooperating successively of pole 11, throw off mutually in order to prevent extension ladder each terraced body 1 when opening and using or pack up, two ends the pole 11 of each terraced body 1 are respectively equipped with block 5, throw off mutually thereby the displacement when sliding by block 5 control sliding sleeves 4 prevents extension ladder each terraced body 1 when opening and using or pack up.And on the terraced body 1 that is positioned at safety extension ladder the top, be provided with the fixedly fixed part 2 of safety extension ladder, as be separately positioned on the stay hook of two poles, 11 inboards, by stay hook extension ladder is hung to be fixed on windowsill or other fixture and carry out hanging operation, or extension ladder is hung on the afterbody of other ladder by stay hook, to increase ladder length, and stay hook can adopt hinged mode to be connected with pole, and between two stay hooks, be provided with connecting rod 21, like this when not using, its rotation can be packed up, to make things convenient for the storing of extension ladder; Can make extension ladder leave the supporter 9 of ladder attachment and be respectively equipped with in the lower end of each terraced body 1; be respectively equipped with the mode that supports quarter butt as adopting in the lower end of two poles 11 of each terraced body 1; the supporter 9 promotion extension ladders that just can be provided with on the terraced body 1 when using ladder like this leave the surface of the attachment such as the wall that are used to hang ladder by each; increase the user greatly and when climbing, held the area that pin is being stepped on the position, protected the safety of using.
Safety extension ladder is rotating respectively on the pole 11 of each terraced body of terraced body bottom topmost to be provided with mousing-hook 3 being positioned at, when packing up when not using at extension ladder, thereby can hook the stull 12 on the adjacent terraced body or be arranged on other parts on the adjacent terraced body each terraced body be hooked by mousing-hook 3, prevent to throw off each other, be convenient to storing, and can between mousing-hook 3 and pole 11, be provided with spring, effect by spring, the stull 12 on the adjacent terraced body is hooked in promotion mousing-hook 3, strengthens its safety.
Security performance when using in order further to strengthen extension ladder, be connected with drag hook 23 on the top that is positioned at the terraced body in extension ladder the top by rope 22, when using ladder, after ladder is hung up properly, drag hook 23 can be hooked and is fixed in a safe fixed point, again with rope 22 tension and fastening getting final product.The stull 12 of each terraced body can be adopted and be in-line, with simplified structure, and the volume that reduces.And the supporting protection rope of safety extension ladder can be used, when under nonemergency, using this extension ladder like this, can slowly open extension ladder, with the application life of director's ladder by the pulling of protection rope.
Because the working environment difference when using extension ladder to carry out operation, therefore the length that needs extension ladder to stretch out is also different, for solving this phenomenon, as shown in fig. 1, on the pole 11 of each terraced body, be arranged in order respectively and be provided with some jacks 6, and the top of pole 11 that is positioned at the terraced body of bottom in each adjacent terraced body is respectively equipped with latch 7, like this, just can come length by cooperating between latch 7 and the jack 6 according to operating environment adjustment extension ladder.
