Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings, which are provided for purposes of illustration and not limitation.

Referring to fig. 1-3, a portable folding basin comprises a basin body and a basin bottom 1, wherein the basin body comprises a plurality of bendable supporting arms and a flexible waterproof membrane 4, the plurality of supporting arms are uniformly distributed along the edge circumference of the basin bottom 1, and the flexible waterproof membrane 4 covers the basin bottom and the plurality of supporting arms and forms an annular closed structure.

When the folding basin is unfolded, the supporting arm is in a linear structure and extends to the edge of the basin bottom in a reflection shape.

The support arm includes lower support arm 2 and last support arm 3, and the one end and the pelvic floor of lower support arm 2 are connected, and the other end of lower support arm 2 is connected with the one end of last support arm 3.

Specifically, the portable folding basin in this embodiment comprises six support arms, and when expanding the use, upwards bends the free end of last support arm 3, makes it be the linear structure with lower support arm 2, then makes the support arm of linear structure outwards expand, and six support arms are radial, and simultaneously, flexible waterproof membrane expandes completely, and the tension that produces forms the holding power to a plurality of support arms, makes the pelvic floor and support arm form the potted structure.

Further, the connecting portion of the upper supporting arm 3 and the lower supporting arm 2 is provided with a first bending groove 5, and the connecting portion of the lower end of the lower supporting arm 2 and the basin bottom 1 is provided with a second bending groove 6.

When needs are accomodate, at first make lower support arm 2 rotate to the central direction of the basin body along second bending groove 6, then make support arm 3 rotate to the outside of the basin body along first bending groove 5, at last, draw together lower support arm 2 and last support arm 3 to basin body central point for the folding basin after accomodating is columniform structure, accomplishes the state of accomodating promptly.

In addition, the flexible waterproof film is in a free state during storage, and is freely deformed in accordance with the stored state.

And a layer of waterproof membrane covers the bottom of the basin bottom and the outer side walls of the plurality of supporting arms, and the flexible waterproof membrane is fan-shaped in a spreading state. In order to ensure the waterproof performance of the folding basin, the lower end of the flexible waterproof membrane covers the edge area of the basin bottom or covers the bottom of the whole basin bottom.

Further, the inner side wall of the supporting arm and the top surface of the pot body are covered with flexible waterproof membranes, and meanwhile, the two layers of flexible waterproof membranes are bonded to increase the pressure bearing performance of the pot body, and the pot body can also be understood as being provided with one layer of flexible waterproof membrane.

The waterproof membrane is a polyethylene waterproof membrane or a silica gel membrane.

And the polyethylene waterproof film is bonded on each supporting arm by adopting a bonding method.

The silicone membrane is formed on the support arm and the basin bottom in an injection molding mode.

The bottom of the basin bottom 1 is also provided with a supporting part, so that the basin bottom is separated from the ground, the damage of a waterproof membrane caused by the moving process of the basin bottom is prevented, and the service life of the folding basin is prolonged.

The supporting parts are uniformly distributed on a plurality of supporting blocks or supporting rings at the bottom of the basin.

Basin bottom 1 and support arm adopt the integrative injection moulding of mould, and the material of adoption is the PP material, because the PP material has high tenacity, consequently can not produce the fracture at the in-process of bending repeatedly, leads to folding basin to leak.

The mould includes mould 7 and lower mould 8, upward all be provided with the shaping face of folding basin on mould 7 and the lower mould 8, merge as mould 7 and lower mould 8, form the injection molding chamber of folding basin between the shaping face of its upper mould 7 and lower mould 8, the PP plastics of molten state is through keeping in the inflow injection molding chamber, treat the plastic molding back, then open and go up mould 7, take out fashioned folding basin, then along first groove 5 and the second groove 6 that bends, the support arm of buckling, can form the integrated configuration of support arm and pelvic floor.

When the silicone membrane is formed, a set of silicone mold is required to be manufactured, the silicone mold comprises a male mold and a female mold, fixing positions of a supporting arm and a basin bottom and a forming cavity of the silicone membrane are reserved on the male mold and the female mold, and the forming cavity is communicated with a cavity at the fixing positions; and during injection molding, the supporting arm is in an unfolded state, the basin bottom and the supporting arm are installed in the male die and the female die, and finally molten silica gel is injected into the silica gel die to complete the manufacture of the folding basin. The mold forming method adopts a conventional injection molding process and a silica gel injection molding process.

The utility model has the expansion use state and the storage state; when in use, the pot body is only required to be stretched outwards, and the supporting arm is unfolded to be used. When the basin is folded and stored, the support arms are folded along the flexible folding parts and then drawn close to the center of the basin body, so that the storage state can be completed. The utility model discloses simple structure, folding back size is small and exquisite, and convenient to accomodate and carry makes things convenient for people to carry when going out to travel to low in production cost, very convenient and practical is fit for a large amount of popularization and application.

The above contents are only for explaining the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical solution according to the technical idea of the present invention all fall within the protection scope of the claims of the present invention.
