Description
Technical field
Ladder technical field is the utility model is related to, more particularly, to a kind of buffer structure and extension ladder.
Background technology
Ladder is the ascending tool commonly used in daily life, stretchs out, does not have to wherein extension ladder can elongate when being a kind of practical
When can collapse shorten storage operation of ascending a height ladder.Common extension ladder by it is main it is terraced formed with secondary ladder, main ladder, the terraced frame of secondary ladder
It is C-shaped section bar or cast section bar, secondary ladder is interspersed on main ladder, has hook on secondary ladder, can be hung on main ladder, has cunning on main ladder
Wheel, by pulling rope, secondary ladder be free to rise or fall, and such a extending ladder can only be used uprightly, and used
When, it is necessary to be hooked on pinnacled fixture.And such a extension ladder, it is typically all that two to three people go to operate when in use,
It is raised to after using height, then is hooked on pinnacled fixture, user can just climbs, work.Rope is by plastic optical fibre (PP
Or PA) work out, after long-time use, it may appear that the phenomenon of aging, breakage and fracture, if when ladder is used
When, rope is surprisingly broken, and secondary ladder will slide downwards, can cause the damage of ladder in itself.
Therefore extension ladder of the prior art, on the problem of secondary ladder is inadvertently fallen off, without precautionary measures, secondary ladder meaning is caused
It is outer when dropping, easily there is state of weightlessness, what the hook on secondary ladder can not be stablized hang on main ladder, not only result in ladder in itself
Damage, even user can be caused injured when serious.
The information for being disclosed in the background section is merely intended to deepen the reason to general background technology of the present utility model
Solution, and be not construed as recognizing or imply known to those skilled in the art existing of the information structure in any form
Technology.

The cushion 500 being connected with attachment structure 400 can be facilitated to move；Even if cushion 500 be worn it is thinning after, elastic component also can
Continue to extrude cushion 500, throw away cushion 500 and be in close contact with ladder, play a part of buffering.
To the buffer structure of the present utility model being described in detail as can be seen that the present embodiment provides with reference to more than, including with
The connected guide sleeve 100 of ladder, guide sleeve 100 is connected with pressing plate 200, and pressing plate 200 is formed with the through hole inside guide sleeve 100
Cavity volume；Cavity volume is internally provided with elastic component, and elastic component side contacts with pressing plate 200, and opposite side contacts with attachment structure 400；Even
Binding structure 400 is connected with cushion 500.Because elastic component side contacts with pressing plate 200, opposite side and cushion 500 is connected with
Attachment structure 400 contact, so the setting of elastic component can be in close contact cushion 500 and ladder, and even if buffering
Layer 500 be worn it is thinning after, elastic component can also continue extrude cushion 500, make cushion 500 throw away and ladder be in close contact；I.e.
When inadvertently falling off secondary ladder, by the setting of cushion 500, the problem of weightlessness can be avoided the occurrence of, and then avoid ladder sheet
The problem of impaired and user's injury of body.
Embodiment two
Fig. 5 is the structural representation for the extension ladder that the utility model embodiment provides；Fig. 6 carries for the utility model embodiment
The front view of the extension ladder of confession；Fig. 7 is the right view for the extension ladder that the utility model embodiment provides.
As illustrated in figs. 5-7, the extension ladder that the present embodiment provides, including：Main terraced frame 600 and slided with main terraced frame 600
The terraced frame 700 of pair of connection, the secondary terraced side of frame 700 connect above-mentioned buffer structure；More main ladders are set on main terraced frame 600
Riding club 601, the terraced riding club 701 of more pairs is set on secondary terraced frame 700；Hook 702 is installed with secondary terraced frame 700, is linked up with 702
Lifting rope 703 is connected with, lifting one end of rope 703 is connected with the top of hook 702, and the other end sequentially passes through more main terraced riding clubs
601 and roller after be connected with secondary terraced frame 700.
Specifically, the main terraced bottom of frame 600 is provided with the foot of ladder 602 for supporting ladder, the main terraced top of frame 600 is set
There is the locating part 603 for limiting the secondary terraced displacement of frame 700, just do not exist after secondary terraced frame 700 rises to certain distance
Rise, secondary terraced frame 700 can be avoided to depart from main terraced frame 600.
Further, support member 604 is provided between the main bottom of terraced riding club 601 and the main terraced side wall of frame 600, improves main ladder
The weight capacity of terraced frame 600.
Preferably, support member 604 is provided between the secondary terraced bottom of riding club 701 and the secondary terraced side wall of frame 700, improves secondary ladder ladder
The weight capacity of frame 700.
It should be noted that buffer structure is arranged on the both sides of secondary terraced frame 700, and the installation site distance of buffer structure
At the 300mm of the secondary terraced bottom of frame 700, and it is fixedly connected by rivet with secondary terraced frame 700.
In the present embodiment alternative, 702 sides of hook are fixedly connected with secondary terraced frame 700, opposite side and main terraced riding club
601 are flexibly connected, when secondary terraced frame 700 rises, with the hook 702 that secondary terraced frame 700 is fixedly connected with secondary terraced frame 700
Rise and rise, and then depart from main terraced riding club 601 with secondary terraced frame 700 with the hook 702 that main terraced riding club 601 is flexibly connected
Rise and rise.
It should be noted that when secondary terraced frame 700 rises, hook 702 departs from main terraced riding club 601 with secondary terraced frame
700 rise and rise, and the one end for the lifting rope 703 being now connected with the top of hook 702 is also with rising, due to lifting rope
703 entire length is constant, simply as secondary terraced frame 700 rises, if group in order to fasten the terraced frame 700 of pair, can
Secondary terraced frame 700 is avoided to climb away main terraced frame 600.
To the extension ladder of the present utility model being described in detail as can be seen that the present embodiment provides, including main ladder with reference to more than
Terraced frame 600 and the terraced frame 700 of pair being slidably connected with main terraced frame 600, the secondary terraced side of frame 700 connect above-mentioned buffering knot
Structure；More main terraced riding clubs 601 are set on main terraced frame 600, the terraced riding club 701 of more pairs is set on secondary terraced frame 700；Secondary terraced frame
Hook 702 is installed with 700, lifting rope 703 is connected with hook 702, lifting one end of rope 703 connects with the top of hook 702
Connect, the other end is connected after sequentially passing through more main terraced riding clubs 601 and roller with secondary terraced frame 700.Due to the setting of buffer structure,
So extension ladder there are all advantages of above-mentioned buffer structure, it is broken even if there is lifting rope 703, when secondary ladder is inadvertently fallen off,
Also be not in state of weightlessness, and rubbed caused by buffer structure by the setting of buffer structure, it is sufficient to when the secondary ladder is dropped
Slow down, the hook 702 allowed on secondary terraced frame 700 is smoothly suspended on main terraced frame 600, and then avoids ladder being damaged in itself
And the problem of user's injury.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
