Description
Technical field
The invention belongs to climbing tool fields, and in particular to a kind of telescoping tube guide sleeve and a kind of telescoping tube staircase.
Background technology
Common ladder is single ladder bed structure, including two ladder bars arranged in parallel and is located at two ladders
Cross bar between bar, cross bar is as support level.It is this list ladder bed structure ladder when in use, due to there is no fixed structure,
It need to be resisted against on supporter and could stand, and easily topple over, safety in utilization is low.To enhance the safety in utilization of ladder, occur
Double ladder.However, double ladder is when in use, two ladder openings need to be supported on ground, larger working space need to be occupied.
In addition, the use height of above two ladder is fixed so that its use occasion has very big limitation.When needing to pick and place eminence article
When, it needs using longer ladder, and compared with long ladder since its volume is big, center of gravity is high, safety in utilization reduces, and carries not
Just, take up space bigger during storage.
The various extension ladders of current market circulation are more, but when being withdrawn again after pull is opened, all there are one very big
Operation hidden danger, exactly hold ladder pipe or pedal shrink when can be forced into hand or finger, as slightly not note that have injury wind
Danger, relatively common settling mode are to increase rubber cushion blocks, but also have and push down injury by rubber pad between two section pedals
Risk, and be not most economical mode.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is explained in further detail.It should be appreciated that specific embodiment described herein is used only for explaining the present invention, and
It is not used in the restriction present invention.On the contrary, the present invention cover it is any be defined by the claims the present invention spirit and scope on do
Replacement, modification, equivalent method and scheme.Further, in order to which the public is made to have a better understanding the present invention, below to this
It is detailed to describe some specific detail sections in the datail description of invention.It is thin without these for a person skilled in the art
The description of section part can also understand the present invention completely.
The invention will be further described in the following with reference to the drawings and specific embodiments, but not as a limitation of the invention.
Below most preferred embodiment is enumerated for the present invention：
As shown in Figure 1-Figure 3, telescoping tube guide sleeve of the present invention is used to connect pipe end and down tube top on extension ladder.It is a kind of
Telescoping tube guide sleeve, the guide sleeve include the first baffle plate 1, the second baffle plate 2, sealing ring 3, connecting plate 6, guide sleeve ontology
4th, supporting member 7 and air hole 5.
First baffle plate 1 is connected to the outside at 4 middle part of guide sleeve ontology.
Second baffle plate 2 is connected to the outside of one end of the guide sleeve ontology 4, first baffle plate 1 and
Two baffle plates 2 form a groove 51.
The guide sleeve ontology 4 for middle part be equipped with an interlayer 41 column structure 42,41 edge of interlayer in contrast to
The other end of second baffle plate 2 extends two limiting slots 43, and two limiting slots 43 are in the column structure 42
Side be equipped with limit hole 44, another side that the column structure 42 is different from two limit holes 44 is equipped with an opening
45,45 height of the opening are identical with 44 height of limit hole.
Second baffle plate 2 connects first baffle plate 1 by the connecting plate 6, and the connecting plate 6, which is arranged on, leads
To 4 outside of set ontology, 2 thickness all same of the connecting plate 6, first baffle plate 1 and second baffle plate.
The sealing ring 3 and air hole 5 are arranged in the groove 51, and 3 height size of sealing ring is less than described
51 width size of groove, the sealing ring 3 are semi-ring, and 3 both ends of sealing ring are connected with the connecting plate 6, are adhered on described
4 side of guide sleeve ontology.
The supporting member 7 is connected with connecting plate 6, and with opening 45 in the same side, the supporting member 7 is from connecting plate 6 to opposite
In opening 45 the other end extend two it is triangular prism shaped into.
A kind of telescoping tube staircase, the staircase include the first telescoping tube 8, the second telescoping tube 9 and fixed pin.
First telescoping tube, 8 radius is less than 9 radius of the second telescoping tube, and first telescoping tube 8 is located at described the
In two telescoping tubes 9, the 8 side lower end of the first telescoping tube set there are two with 44 size of limit hole and relative position all same
Pin hole 81.
The pin hole 81 passes through limit hole 44 described in fixed pin connection.
3 outer diameter of sealing ring is more than the internal diameter of second telescoping tube 9, the sealing ring 3 using wear-resisting plastics or
Other wear-resistant materials of person.
Operation principle, when the first telescoping tube 8 rises because guide sleeve and the first telescoping tube 8 by limit hole 44,
The bolt of pin hole 81 and fixed pin combine, be fixed together, sealing ring 3 is socketed in the outside of guide sleeve, above with following point
It is not made of the first baffle plate 1 and the second baffle plate 2.The internal diameter of 3 the second telescoping tube of size ratio 9 of sealing ring is slightly larger, so sealing
Ring 3 can have frictional force with the inside of the second telescoping tube 9, when the first telescoping tube 8 drives them to be transported upwards relative to the second telescoping tube 9
When dynamic, frictional force can allow sealing ring 3 to be adjacent to the second baffle plate 2, and the air hole 5 above guide sleeve will expose, and be sealed in the
One telescoping tube 8 is connected with the air in the second telescoping tube 9 by this air hole 5, and the first telescoping tube 8 can move up easily.
, whereas if the first telescoping tube 8 drives guide sleeve and sealing ring 3 to be moved downward relative to the second telescoping tube 9, rub
Power can allow 3 upward first baffle plate 1 of sealing ring, and sealing ring 3 can block air hole 5 at this time, will be present in 8 He of the first telescoping tube
Air in second telescoping tube 9 seals.At this time because the reason of air pressure, action that the first telescoping tube 8 glides will be by
It hinders.Because sealing ring 3 can not be completely by air containment, partial air passes through in 3 and second telescoping tube 9 of sealing ring
Minim gap is escaped, so as to reach the action that the first telescoping tube 8 is hindered to glide.Realize that is be previously mentioned prevents extension ladder downslide too fast
Function.The sealing ring 3 being previously mentioned uses wear-resisting plastics or other wear-resistant materials.
One kind of embodiment described above, only more preferably specific embodiment of the invention, those skilled in the art
The usual variations and alternatives that member carries out in the range of technical solution of the present invention should all include within the scope of the present invention.
