Abstract
The utility model relates to the field of plastic processing, in particular to a pre-buried structure of a rotational moulding product insert, which comprises a transparent insert provided with an internal screwed hole; the transparent insert is embedded in a rotational moulding product; the outer surface and the inner surface of the rotational moulding product are communicated with each other by an inner hole of the transparent insert; the outer surface of the transparent insert is concave on the outer surface of the rotational moulding product; an externally connected screwed pipe of an externally connected part is matched with the inner hole of the transparent insert; and a sealing gasket is used for sealing a fastening piece of an externally connected pipe body and the outer surface of the rotational moulding product, so that the phenomenon of leakage is avoided.
Description
Technical field
The utility model relates to field of plastics processing, particularly a kind of pre-buried structure of rotational moulding product inserts.
Background technology
At present, the built-in process of rotational moulding product inserts all is that penetrating inserts exposes, and the junction of penetrating inserts and rotational moulding product is loosening easily, produces the slit, causes seepage.The internal tank that the rotational moulding product is made has certain pressure, and the inside and outside of penetrating inserts communicates, and more is easy to generate the seepage phenomenon.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, can effectively prevent to produce the pre-buried structure of the rotational moulding product inserts of seepage.
For achieving the above object, the present invention has adopted following technical scheme: a kind of pre-buried structure of rotational moulding product inserts, comprise the penetrating inserts that is provided with internal thread hole, penetrating inserts is embedded in the rotational moulding product, the outer surface of rotational moulding product and inner surface are communicated with the outer surface of the recessed rotational moulding product of the outer surface of penetrating inserts by the endoporus of penetrating inserts.
Owing to adopt above technical scheme, the outer surface of the recessed rotational moulding product of outside face of penetrating inserts, the external connection screw pipe of outer relay part cooperates with the endoporus of penetrating inserts, adds the sealing gasket sealing between the outer surface of securing member on the external body and rotational moulding product, has avoided the seepage phenomenon.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an assembly structure schematic diagram of the present utility model.
The specific embodiment
As Fig. 1, a kind of pre-buried structure of rotational moulding product inserts, comprise the penetrating inserts 10 that is provided with internal thread hole, penetrating inserts 10 is embedded in the rotational moulding product 20, the outer surface 21 of rotational moulding product 20 and inner surface 22 are communicated with by the endoporus of penetrating inserts 10, the outer surface 21 of the outer surface 11 recessed rotational moulding products 20 of penetrating inserts 10, the faying face of outer relay part 30 and penetrating inserts 10 is positioned at the inside of rotational moulding product 20, during assembling, on the outer surface of rotational moulding product 20 and outside add sealing gasket 40 sealings between the relay part 30, further effectively avoid producing the seepage phenomenon.
Further, described penetrating inserts 10 is the body of non-circular side face, prevents that penetrating inserts 10 from producing play.
Further, the wall thickness dimension at described rotational moulding product 20 pre-buried penetrating inserts 10 positions is saved material greater than the wall thickness of its side when satisfying topology requirement, reduce product cost.
Further again, described penetrating inserts 10 embeds the wall thickness inside of rotational moulding product 20 fully, penetrating inserts 10 all has the counterbore 23 that extends to penetrating inserts 10 surfaces with the outer surface 21 and inner surface 22 places of rotational moulding product 20, the aperture of counterbore 23 is greater than the internal orifice dimension of penetrating inserts 10, adopt the processing technology of this structure simple, can guarantee that also the surfaces externally and internally of rotational moulding product 20 is communicated with smooth and easy.
Further, described penetrating inserts 10 is a nut structure, and the intermediate portion is divided into optical axis, and its diameter of axle is less than the diameter of two end nuts, adopt this structure, the axial and circumferential of penetrating inserts 10 are all played firm spacing, the connection of convenient so outer relay part.
