Description

Rain leakage prevention joint structure of umbrella

Technical Field

The utility model relates to an umbrella manufacturing technology field especially relates to an umbrella's leak protection rain seam structure.

Background

In life, the umbrella is an indispensable article, as is well known, the umbrella surface of the umbrella is of a spherical structure or a paraboloidal structure, the umbrella surface is formed by sequentially sewing a plurality of pieces of triangular umbrella surface cloth and triangular umbrella surface cloth together by using threads, and the umbrella surface is formed by sewing more than four pieces of triangular umbrella surface cloth together by using threads instead of a complete integral umbrella surface. Because the triangular umbrella surface cloth and the triangular umbrella surface cloth are connected by needle sewing, the umbrella surface of the umbrella is bound to have a gap between a sewing needle hole and a non-sewing needle hole between the sewing needle holes, and an assembly gap exists between the top of the umbrella surface and an assembly node of an umbrella rib, so all umbrellas have the possibility of rain leakage. Particularly, under the condition of heavy rainstorm, the dropping force and density of rainwater are higher, the water tension of a gap between a needle hole and a needle hole is not enough to resist the force of dripping water, and the umbrella is obviously leaked, so that the problem is solved by the rain leakage prevention joint structure of the umbrella.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the assembly gap between the needle hole and the umbrella surface top of the existing splicing seam of the existing umbrella in the prior art leads to rain leakage, and providing a rain leakage prevention seam structure of the umbrella.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the design is a rain leakage prevention seam structure of umbrella, including a plurality of triangular piece face cloths, it is a plurality of triangular piece face cloth forms circular umbrella face through sewing up, the centre of a circle portion of circular umbrella face is equipped with the pilot hole that runs through of rib, the inside and outside both sides coating respectively of the portion of sewing up of triangular piece face cloth is equipped with the bar film, the inside and outside both sides coating respectively of the pilot hole that runs through is equipped with the annular film.

Preferably, the strip-shaped adhesive sheet has a coating width 2 to 3 times the width of the seam.

Preferably, the annular films are pressed on one side of the strip-shaped film, which is far away from the triangular piece shell fabric.

Preferably, the strip-shaped rubber sheet and the annular rubber sheet are both of PU glue structures, and the coating process of the strip-shaped rubber sheet and the annular rubber sheet is a heating seamless attaching process.

Preferably, the coating thickness of the strip-shaped film and the annular film is 0.1-0.5 mm.

The utility model provides a pair of rain leakage prevention seam structure of umbrella, beneficial effect lies in: the utility model discloses a coating bar film and annular film respectively on the portion of sewing up of umbrella and the assembly hole that runs through at umbrella top, the assembly node at the pinhole of sewing up and the umbrella top of making the portion of sewing up of umbrella reaches airtight effect, has comprehensively airtight umbrella face, has better rain leakage prevention function, and the practicality is strong.

Drawings

FIG. 1 is a schematic top view of an umbrella with rain leakage preventing seam structure;

fig. 2 is a schematic bottom structure view of the rain leakage preventing seam structure of the umbrella of the present invention.

In the figure: triangular piece surface cloth 1, strip-shaped rubber sheets 2 and annular rubber sheets 3.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a rain leakage prevention seam structure of an umbrella comprises a plurality of triangular piece cloths 1, the seam parts of two adjacent triangular piece cloths 1 of an umbrella cover are spliced together, the spliced seam parts are folded, the folded parts are sewn by using a sewing thread to form a sewing part, the folded parts are sewn to improve the sealing property of the seam parts, the triangular piece cloths 1 are sewn to form a circular umbrella cover, the circle center part of the circular umbrella cover is provided with a through assembling hole of an umbrella rib, the structure of the umbrella rib can be a three-fold umbrella rib or a two-fold umbrella rib structure, the inner side and the outer side of the sewing part are respectively coated with a strip-shaped rubber sheet 2, the coating width of the strip-shaped rubber sheet 2 is 2-3 times of the width of the sewing part, the leakage prevention protection range is improved, the inner side and the outer side of the through assembling hole are respectively coated with an annular rubber sheet 3, annular film 3 is all pressfitting and is kept away from at bar film 2 triangle piece face cloth 1's one side avoids the position rain seepage of 2 handing-over of a plurality of bar films, has further promoted waterproof performance, bar film 2 reaches annular film 3 is PU glued structure, bar film 2 reaches annular film 3's coating process is the seamless laminating process of heating, bar film 2 reaches annular film 3's coating thickness is 0.1-0.5mm, reaches better aesthetic property.

The utility model discloses a coating bar film 2 and annular film 3 respectively on the portion of sewing up of umbrella and the assembly hole that runs through at umbrella top, the assembly node at the pinhole of sewing up and the umbrella top of making the portion of sewing up of umbrella reaches airtight effect, has comprehensively airtight umbrella face, has better rain leakage prevention function, and the practicality is strong.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
