Abstract
The utility model relates to the technical field of rain gears, in particular to a plastic rib device of a multi-folded umbrella. In the technical scheme, one end of a middle supporting rib is connected with a lower supporting rib via a rivet, the other end is connected with an upper supporting rib via a rivet, one end of a supporting rib is hinged with the upper supporting rib, both ends of an accessory rib are hinged with the supporting rib and the middle supporting rib, a groove is arranged on the middle supporting rib, a through hole is arranged in the groove, a U-shaped sheet penetrates the through hole, both ends of the U-shaped sheet are clamped on the outer edges of the through hole, a tendon penetrates the U-shaped sheet to form a U-shaped hole, and both ends of the tendon are hinged with the upper supporting rib and the lower supporting rib. By applying the device, an umbrella can be more conveniently and easily unfurled and furled, moreover, the umbrella is solider, and the service life is increased.
Description
Technical field:
The utility model relates to the rain gear technical field, refers in particular to a kind of plastic umbrella device that is used for multi-fold umbrella.
Background technology:
Because folding parachute kit can fold placement, and is easy to carry, thereby current use is more.It is light with it, practical characteristics is subjected to people's favor deeply.But also there are some shortcomings in it, for example multi-fold umbrella will draw parachute kit in after use, and because rainwater produces certain force of strain on the surface of parachute kit, when parachute kit is folded and be not easy, particularly middle ramus and lower support rib junction need by hand it to be closed up especially, make troubles to the user.And umbrella framework adopts aluminium to make mostly at present, and middle ramus often is subjected to certain external force when parachute kit uses, and wind-force etc. for example is because the intensity of aluminium is not high, so be easy to cause middle ramus bending, distortion even fracture, cause the service life of parachute kit not long.
Summary of the invention:
The purpose of this utility model is to provide a kind of folding easy, light, and durable plastic umbrella device.
The utility model is achieved by the following technical solution: an end of middle ramus is connected by rivet with lower support rib, the other end is connected by rivet with upper ramus, one end of fulcra is hinged on the upper ramus, the two ends of secondary bone are hinged on fulcra and the middle ramus, a groove is arranged on the middle ramus, and offer a through hole in the groove, the U-shaped sheet passes through hole, and two ends are fastened on the through hole outer rim, and rib passes the U-shaped hole that the U-shaped sheet forms, and its two ends are hinged on upper ramus and the lower support rib.
After adopting this structure, because the effect of rib, parachute kit makes tightr that lower support rib combines with middle ramus, thereby makes umbrella cover along cunning when opening under the effect of rib elastic force.And adopt the umbrella rib device of plastic material manufacturing to have higher toughness.Rib can be free movable in the U-shaped hole that the U-shaped sheet forms simultaneously, thereby make parachute kit folding freedom, flexible.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the three-dimensional structure diagram of the utility model middle ramus;
Fig. 3 is the utility model partial enlarged drawing.
The specific embodiment:
See accompanying drawing 1,2,3, the utility model comprises: upper ramus 1, secondary bone 11, middle ramus 2, rib 21, lower support rib 3 and fulcra 4, one end of middle ramus 2 and lower support rib 3 are connected by rivet, the other end and upper ramus 1 are connected by rivet, one end of fulcra 4 is hinged on the upper ramus 1, the two ends of secondary bone 11 are hinged on fulcra 4 and the middle ramus 2, one groove 24 is arranged on the middle ramus 2, and offer a through hole 22 in the groove 24, U-shaped sheet 23 passes through hole 22, and two ends are fastened on through hole 22 outer rims, and rib 21 passes the U-shaped hole that U-shaped sheet 23 forms, and its two ends are hinged on upper ramus 1 and the lower support rib 3.Rib 21 has big activity space in the U-shaped hole that U-shaped sheet 23 forms.Middle ramus 2 adopts the plastic material manufacturing.
When using the utility model, after opening parachute kit, fulcra 4 promote upper ramus 1 and outwards open, and drive secondary bone 11 successively, middle ramus 2 opens, wherein upper ramus 1, middle ramus 2, rib 21 and lower support rib 3 form the linkage of an approximate parallelogram, so when upper ramus 1 rotation, upper ramus 1 is by rib 21 pulling lower support ribs 3 simultaneously, lower support rib 3 is opened, and these skeletons support umbrella cover together.When not in use, parachute kit is folded, fulcra 4 pulling upper ramus 1 down draw in, and drive secondary bone 11, middle ramus 2 gatherings successively, and upper ramus 1 closes up lower support rib 3 rotations by rib 21 pulling lower support ribs 3, and parachute kit is drawn in like this.In the utility model, rib 21 can be free movable in U-shaped sheet 23, thereby make parachute kit folding freedom, flexible.
