A kind of straight bone automatic reverse umbrella structure
Technical field
This utility model relates to a kind of umbrella structure, is specifically related on a kind of umbrella stand be provided with the structure that can reversely close one's umbrella to keep away
The opisthotonos umbrella that after exempting from umbrella, rain exumbrella faces outwardly.
Background technology
Usually be unableing to do without umbrella in life, umbrella is the rainy day to use most rain cover apparatus, current various vertical frame umbrellas, all uses
The umbrella movement that umbrella cover and umbrella stand close up downwardly together, has automatic receipts in the straight rib self-opening umbrella opening function this, because umbrella
Straight bone shape on handle have employed the form of the most shrinkable straight bone, for excellent umbrella folded against on the middle rod of this straight bone generally
Be arranged with middle nest, in this rod upper end be fixed with nest, described handle be fixed in this rod middle lower end, on upper nest connect have in
Radial pivot joint, to support the main support of umbrella cover, lower nest is the most radially articulated with assistant support, and this assistant support is the most right
Answering ground corresponding with main support and connect, this lower nest is set on middle rod and can along middle rod slidably, and umbrella cover is then coated on
On described main support.
This umbrella when in use, because the outside of umbrella cover generally the most necessarily has a lot of rainwater, and draws umbrella in
Time outside, umbrella cover is all downward along with main framing shrinks, and surrounds downwardly together on the umbrella cover that umbrella shaft is shunk after contraction, because
Upper at umbrella cover is generally all to be covered with rain, hence into building or other without the space of rain after, usually cannot be well
Storage umbrella, this brings trouble to the use of people, it is therefore desirable to improves current umbrella frame structure, makes the umbrella after storage
Outside do not have a lot of rainwater.

The inner and described lower nest on corresponding position be hinged.
In one of the present utility model straight bone automatic reverse umbrella structure, described umbrella cover is exumbrella and sub-umbrella, umbrella on this
Face coordinates with described main support, and the umbrella stand that this described sub-umbrella is constituted with the auxiliary rod of downside coordinates.
One of the present utility model straight bone automatic reverse umbrella structure, have employed above-mentioned structure, can during closing one's umbrella
It is that the focus drawn in rotates to realize the following nest of umbrella stand, thus closing one's umbrella of realizing that umbrella cover is folded upward at, thus rainwater will be speckled with
Outer umbrella cover be close between nest and main support, it is to avoid the umbrella cover of rain is outside, in therefore indoor in turnover or car time
Time can provide conveniently with consumer, and avoids contacting of wet umbrella cover and surrounding dry goods.
Close detailed content of the present utility model and technology, hereby just coordinate accompanying drawing to be described as follows.
Accompanying drawing explanation
Fig. 1 is the structural representation that umbrella stand opens;
Fig. 2 is the enlarged drawing of the A of Fig. 1.
Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2, for this utility model preferred embodiment, bounce-back umbrella structure bag in the present embodiment
Having included middle excellent 17, upper nest 11, lower nest 3, handle 2, main support, assistant support 16, middle rod is arranged with middle nest, in this, the upper end of rod is solid
Surely there are upper nest, described handle to be fixed in this middle lower end of rod, having radially pivot joint to support umbrella cover if connecting on upper nest
A dry main support, lower nest is radially articulated with several assistant supports, this each assistant support respectively correspondingly with main support pair
Should and connect, this lower nest 3 is sheathed on middle rod and can along rod in this slidably, and described umbrella cover is then coated on described
The outside of main support, also includes spring 13, gag lever post 5 and some auxiliary rods 15, and described each main support is divided into mutually hinge
The mobile jib 18 connect and secondary bar 19, the upper end of this mobile jib is connected with described upper nest, and the medial extremity of described assistant support is mutual with lower nest
Connecting, this mobile jib is hinged in the outer end being provided with assistant support hinge axis hole and described assistant support near the part of outside end,
Described gag lever post is the shaft-like structure that centre is provided with elongated spacing hole, and one end of this gag lever post and described mobile jib are
Gag lever post hinge hole set by outer end is hinged, and the two ends of described spring are connected with described mobile jib and gag lever post respectively,
Described mobile jib outermost is provided with the groove 26 being folded upward at being formed, and the inner place of this groove is provided with secondary bar hinge axis hole and described pair
The inner of bar is hinged, this pair bar hinge hole be positioned at the gag lever post hinge hole of the outermost end of mobile jib and assistant support hinge hole it
Between, the outer end of the described auxiliary rod outermost end through the spacing hole on gag lever post and with described secondary bar is hinged, described auxiliary
The position helping the inner of bar corresponding with on described lower nest is hinged.
Further, described umbrella cover is exumbrella and sub-umbrella, and this exumbrella coordinates with described main support, and this is described
The umbrella stand that constitutes of the auxiliary rod of sub-umbrella and downside coordinate.One of the present utility model straight bone automatic reverse umbrella structure, uses
Above-mentioned structure, can realize umbrella stand following nest during closing one's umbrella is that the focus drawn in rotates, such that it is able to realize
What umbrella cover bent upward closes one's umbrella, it is achieved the outer umbrella cover speckling with rainwater is close in the purpose between upper nest and main support, it is to avoid
