Description
Technical field
The utility model is related to a kind of flexible umbrella shaft.
Background technology
Umbrella is indispensable daily necessities in life, but all a certain degree of presence of umbrella in the market makes
The problem that is not grown with the life-span, and as use time occurs loosening between accessory once growing, one of reason is exactly umbrella
Flexible umbrella shaft structure not reasonable, the middle rod of the Telescope umbrella of prior art is all by the hollow cylinder of many single layer structures
Shape metallic rod is socketed to form, support strength not enough, service life is short, the problems such as, easily cause to rock, affect to use；And deposit
The excessive shortcoming for causing fitness not high of distance between rod in each section because of umbrella shaft of stretching, in metal, rod cannot be deposited in which avoid
In the problem that easily gets rusty.
The patent of Application No. CN201120157994.X proposes umbrella with double-decker umbrella center-stick to solve
Above-mentioned technical problem, outer layer are composite layer, and internal layer is metal level, although to some extent solve umbrella shaft thin
Problem, but this kind of umbrella shaft does not still solve problem of rustiness, and the composite technology of outer layer is complicated, there is cost height etc.
Shortcoming, and stability and intensity to be all not so good as plastics good.
Utility model content
For the deficiencies in the prior art, the utility model is stretched there is provided a kind of thickness is moderate, fitness is high and intensity is big
Contracting umbrella shaft.
For achieving the above object, the utility model provides following technical scheme：Including rod in first segment, rod in second section
With Section three in rod, it is characterized in that：In the first segment, in rod, second section, in rod and Section three, rod includes internal layer and outer layer,
The internal layer is metal level, and outer layer is plastic layer, and the internal layer is embedded in outer layer, and internal layer is coated by outer layer completely.
By above-mentioned technical proposal, middle rod is set to bilayer, improves the intensity of middle rod while improve thickness, extends
There is light weight, stability, the low advantage of intensity high cost, and exposed outer layer to ensure to use for plastics for service life, plastics
Security of the person in thundery sky, it is to avoid umbrella conduction is damaged to user, inner layer metal are used for the intensity for improving umbrella shaft,
Inner metallic layer is embedded in plastic outer layer and can solve the problems, such as that metal level contact water gets rusty easily.
Preferably, the surface of the metal level is provided with multiple projections.
By above-mentioned technical proposal, the projection of metal surface increased the contact surface of metal and plastics, improve metal in modeling
Stability inside material.
Preferably, in the first segment, rod is set in second section on rod, and in described Section three, rod is set in second section
On rod, rod in rod and second section in the first segment, in second section rod with Section three in the distance between rod be 0.15-
0.17mm.
By above-mentioned technical proposal, in first segment, in rod, second section, in rod and Section three, the distance of rod 0.15-0.17 makes three
In section, rod disclosure satisfy that the activity space for carrying out flexible needs, at the same coordinate each other compact, will not be because of apart from excessive
Easily cause and rock.
Preferably, the internal layer thickness is 0.2-0.3mm, and the thickness of outer layer is 0.45-0.5mm.
By above-mentioned technical proposal, enough, and internal layer be the thickness of metal level less than outward to the general thickness of internal layer and outer layer
Layer is that the thickness of plastic layer is easy to internal layer is fixed on outer layer, simultaneously because metal high cost, such thickness design both subtracted
Little cost input, in ensureing again, the thickness of rod and its intensity need.
Preferably, in the first segment, in rod, second section, in rod and Section three, rod is triangular prism shape or cylindric.
By above-mentioned technical proposal, the middle rod of triangular prism shape improves control dynamics of the palm to umbrella shaft.

Specific embodiment
The flexible umbrella shaft of the utility model is further described by Fig. 1 to Fig. 2.
The utility model provides following technical scheme：Including rod in first segment 1, rod in rod 2 and Section three in second section
3, it is characterized in that：In the first segment, in rod 1, second section, in rod 2 and Section three, rod 3 includes internal layer 4 and outer layer 5, described interior
Layer 4 is metal level, and outer layer 5 is plastic layer, and the internal layer 4 is embedded in outer layer 5, and internal layer 4 is coated by outer layer 5 completely, method for coating
Using metal is positioned in mould, pours into after plastic heating is melted
Middle rod in plastic layer.
Preferably, the surface of the metal level is provided with multiple raised 7, makes the uneven increase of layer on surface of metal and plastics
The contact area of layer, improves stability.
Preferably, in the first segment, rod 1 is set in second section on rod 2, and in described Section three, rod 3 is set in second section
