Abstract
The invention discloses a safety extension ladder, which comprises a plurality of ladder bodies composed of a plurality of transverse bracings provided between two supporting rods, wherein the ladder bodies are sequentially slidingly connected through sliding sleeves equipped on the supporting rods, the two ends of the supporting rod are respectively provided with a stopper capable of controlling the sliding displacement of the sliding sleeves, and a fixing portion capable of fixing the safety extension ladder is provided on the ladder body at the most upper end of the safety extension ladder. The invention can not only be conveniently used in midair suspension work, but also has very safe performance.
Description
Technical field
The present invention relates to a kind of ladder, especially relate to a kind of safety extension ladder that passes through the telescopic adjustment length of self.
Background technology
The ladder of the employed fixed ladder body of people formula and telescopic ladder are mostly in use at present is by fixed support bottom ladder, ladder top is shelved on the enterprising enforcement usefulness of other supporter such as house, therefore, they can not well adapt to different environments for use sometimes, as some building outside window or some other in midair operation of suspending, or the situation when dangerous situations such as fire occurring and escaping by window, for addressing this is that, people have adopted the rope ladder that can receive formula hoist cable structure, but rope ladder is because of its structural reason, in use particularly when personnel are in the hanging state, rope ladder rocks easily, allow the user of service that great sense of insecurity is arranged, and because of some reasons of user of service self unnecessary accident takes place on the contrary sometimes.
Summary of the invention
Technical problem to be solved by this invention has provided a kind of safety extension ladder, and it not only can be convenient to use in the situation of the operation that suspends in midair, and uses as safe as a house.
For solving the problems of the technologies described above, technical scheme of the present invention is: safety extension ladder, comprise some by between two poles, being provided with the terraced body that some stulls constitute, described terraced body is slidingly connected successively by the sliding sleeve that is arranged on the pole respectively, the two ends of described pole are respectively equipped with the block that can control the sliding sleeve slide displacement, and the described top that is positioned at safety extension ladder terraced body topmost is provided with the fixedly fixed part of safety extension ladder.
As a kind of improvement, describedly be positioned at that safety extension ladder is rotating respectively on the pole of each terraced body of terraced body bottom 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 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 the safety extension ladder of said structure, the extension ladder that each the terraced body that connects by slip cap load successively combines, and on the terraced body of extension ladder upper end, be provided with the fixedly fixed part of safety extension ladder, like this, people just can hang extension ladder to be fixed on windowsill or other fixture easily and carry out hanging operation, and the shaking phenomenon of rope ladder can not appear, 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.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Fig. 1 is a safety extension ladder of the present invention structural representation in use;
Fig. 2 is safety extension ladder of the present invention structural representation when packing up.
The specific embodiment
According to illustrated in figures 1 and 2, safety extension ladder of the present invention, comprise some by between two poles 11, being provided with the terraced body 1 that some stulls 12 constitute, on the pole 11 of terraced body 1, be provided with sliding sleeve 4, each terraced body 1 is slidingly connected successively mutually by the sliding sleeve 4 that is arranged on the pole 11, 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, increasing 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; 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.
As shown in Figure 1, 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.
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.Simultaneously, in order to make this extension ladder also can be applied to the environment that electric pole etc. has the operation surface of certain radian easily, stull 12 on each terraced body can be designed to protrude from the form of terraced body one side, make the cross bar 8 of stull 12 away from the arc operation surface and be provided with in the bottom of each terraced body.
