Embodiment
To enable the above-mentioned purpose of the utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this
The embodiment of utility model is described in detail.
Referring to Fig. 1, a kind of symmetrical inequilateral umbrella stem, including inside and outside five section pipe fittings being slidably connected successively, it is set to
Pipe fitting 1, pipe fitting 2, pipe fitting 3, pipe fitting 4 and pipe fitting 5, pipe fitting 5 are set on pipe fitting 4, and pipe fitting 4 is set on pipe fitting 3,3 sets of pipe fitting
It is located on pipe fitting 2, pipe fitting 2 is set on pipe fitting 1, in this way, setting gradually, forms the umbrella being slidably socketed between adjacent pipe sections
Bar.
Outermost pipe fitting, i.e. pipe fitting 1, its section polygon, the pipe fitting of internal layer, i.e. pipe fitting 2, pipe fitting 3, pipe fitting 4 and pipe
Part 5, it is equipped with the inner concave 6 of one or one or more whole tubular length direction of extension, preferably to slide, in cunning
In the two neighboring pipe fitting of dynamic socket, the inner concave quantity of internal layer pipe fitting than the inner concave 6 of outer layer pipe fitting quantity more than one, example
Such as, the quantity of the inner concave of pipe fitting 2 can be one or two, then the quantity of the inner concave of pipe fitting 3 can be two or three, successively
Analogize setting, the quantity of the inner concave on pipe fitting can be configured according to actual needs, not discussed one by one herein.As Fig. 2, Fig. 3,
Shown in Fig. 4, Fig. 5 and Fig. 6,6 quantity of inner concave of pipe fitting 2 is one, then 6 quantity of inner concave of pipe fitting 3 is 2, and so on,
So that compact-sized between each pipe fitting, bending resistance is strong, easy to the slip between each pipe fitting.
So that in the forming position of inner concave 6, the pipe fitting of adjacent two layers is not contacted so as to form sky for the setting of inner concave 6
Chamber, remaining position are mechanical matching.In this way, the pipe fitting compared to no inner concave 6 is compared, the bending resistance that can strengthen pipe fitting is strong
Degree so that the smaller that pipe fitting can be done；The cavity of formation so that adjacent pipe fitting slide when, it is more round and smooth smooth, pipe fitting it
Between it is not easy to wear, the slip number between pipe fitting is improved, so as to improve the service life of umbrella.
The utility model is the setting of falling umbrella stem, i.e., outermost pipe fitting 1 connects upper nest and struts umbrella cloth by umbrella frame, most interior
The pipe fitting 5 of layer is connected with handle of umbrella.
In the present embodiment, the section of pipe fitting 1 is symmetrical inequilateral shape, and the length of each length of side in section is set by a certain percentage
Put.As shown in Fig. 2, the section of pipe fitting 1 is arranged to dodecagon, distinguished according to length, be arranged to four article of first side 11, four article
Two at 12, two article the 3rd 13, two articles of the 4th sides 14, two article of the 3rd side 13 be parallel to each other, two article of the 4th side 14 is parallel to each other,
Three 14 are vertically arranged the quadrangle form to form each end and be not connected with 13 and the 4th, first while 11 with second while 12 be connected,
Between first is arranged on the 3rd at 13 and the 4th 14 as a whole at 11 and second after 12 connections and with the 3rd side 13 and the
Four sides 14 connect.Wherein, first at 11, second the 12, the 3rd in 13 and the 4th while 14 length ratio can be 2：3：4：5 are set,
But it is not limited thereto, its each edge lengths ratio also can be according to 3：4：5:6 setting, in other words, first while, second while, the 3rd
While and length ratio when the 4th be not limited to a certain ratio, its length ratio may conform to unequal-sided property.This 12
The length of side of side shape is set according to a certain percentage, and along the vertical 3rd while or along the vertical 4th while straight line it is symmetrical, work as pipe
When the top of part 1 is connected with upper nest, due to its unequal-sided characteristic so that upper nest can be stabilized on pipe fitting 1, prevent partial twist
Phenomenon.In opening process is received, due to the inequilateral characteristic between each pipe fitting so that when receiving parachute-opening, will not be sent out between each pipe fitting
Raw partial twist clamping phenomenon, is conducive to receive parachute-opening, more smooth.Pipe fitting 1 and the lower nest of umbrella are slidably connected, and then play and receive parachute-opening
Effect, lower nest are bonded with the outer wall of pipe fitting 1, and the shape of lower nest is designed according to the shape of pipe fitting 1, can so prevent pipe fitting 5 with
Nest receives partial twist phenomenon during parachute-opening.
In another embodiment, can also there be other length in the section of pipe fitting 1 for the length of side in other shapes and section
Ratio setting is spent, for example, the section of pipe fitting 1 can be octagon, may be provided with three kinds of length of sides, and the length ratio of each length of side can be 2:
3:4, or be 3:4:5, also such as, the section of pipe fitting 1 can be ten hexagons, may be provided with five kinds of length of sides, and the length of each length of side
Than that can be 2:3:4：5:6, or be 3:4:5:6:7.In this way, prevent pipe fitting 1 from occurring with upper nest not influencing the present embodiment
On the basis of partial twist phenomenon, the section of pipe fitting 1 can have various shapes, its length of side species and length ratio can also change.
In the present embodiment, pipe fitting 2, pipe fitting 3, pipe fitting 4, pipe fitting 5 in the length of side for being not provided with inner concave 6, its section
Each length of side is set according to the length ratio of the length of side of pipe fitting 1, as shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, in this way, so that each pipe
Preferably it is socketed between part.
Above-mentioned symmetrical inequilateral umbrella stem, rolls over umbrella stem suitable for more piece, any size size of umbrella stem is rolled over suitable for more piece, its
Material can also have multiple choices, such as metal, plastic or other material.
Above-mentioned symmetrical inequilateral umbrella stem, the cross sectional shape of outermost layer pipe fitting are symmetrical inequilateral shape, and the section length of side
Length is set than according to a certain percentage, due to the inequilateral characteristic of pipe fitting, can prevent partial twist phenomenon.The setting of sunken inside makes
Obtaining the bending resistance of pipe fitting strengthens, the smaller that pipe fitting diameter can be done, the cavity formed between adjacent pipe sections so that between pipe fitting not
Easy to wear, when slip, is more round and smooth smooth, improves the slip number between adjacent pipe sections, extends the service life of umbrella.
Embodiment described above only expresses the several embodiments of the utility model, its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
