Abstract
The utility model relates to a riveting nut, in particular to a nut which is applied to the household appliance. The utility model aims at providing a riveting nut which can save the material and can simultaneously ensure the strength of the product. The utility model adopts the technical scheme that: the riveting nut comprises a nut main body which is of a reversing cup-shaped structure, the bottom end of the nut main body is opened, the side edge of the bottom end is connected with an annular riveting end surface, the top end is provided with a connection hole, and also comprises a nut, the nut is arranged on the top end inside the nut main body, and a threaded hole of the nut corresponds to the connection hole. The riveting nut is mainly applied to the connection assembling of the fixed plate and the circuit board on the household appliances.
Description
Technical field
The utility model relates to a kind of nut, particularly relates to the rivet coating nut that is used on the household electric appliance.
Background technique
Being connected between the fixed plate that rivet coating nut is applicable to household electric appliance and the circuit board, by riveting with nut with after fixed plate is connected, with screw circuit board is fixed on the nut, guarantee its fastening and support performance, existing rivet coating nut is to adopt solid structure mostly, offer screw in the middle, open fluted on the excircle of its riveting end face and nut body connection part, the eliminating of the waste material of turning that is used for or rammer system process, the shortcoming of this product mainly is owing to adopt solid fully structure bigger to the demand of material, and the efficient in processing is low, and needed energy consumption is big; The rivet coating nut that also has is the hollow-core construction that adopts, extend internally one section as screw behind its top drilling, the shortcoming of this product mainly is because the position insufficient strength that extends internally is damaged easily, working life is short, because use amount causes changing very inconvenience more greatly.
The model utility content
The purpose of this utility model provides a kind of rivet coating nut that can guarantee product strength in economical with materials again.
The purpose of this utility model realizes by following technical proposal: rivet coating nut, the nut body that comprises the handstand cup-like structure, its bottom end opening, be connected with ring-type riveting end face on the side of bottom, the top offers attachment hole, also comprise a nut, nut is positioned at the inner tip of nut body, the position correspondence of the tapped hole of nut and attachment hole.
The size of described nut and the internal side wall of nut body are complementary, and the cylindrical sidewall of nut closely contacts with the internal side wall of nut body and is connected.
The periphery of top, the top attachment hole of nut body is connected with a hollow tube-shape maintenance section.
Also comprise a plurality of discharge holes, discharge hole is positioned on the sidewall of nut body of nut body and riveting end face connection part.
The bottom of described nut is higher than the horizontal position at riveting end face place.
From structure characteristic of the present utility model as can be seen, advantage of the present utility model is: with the solid hollow-core construction that is set to of prior art, saved material, improved manufacturing efficiency and reduced cost; At the main stressed position on hollow-core construction top a nut is set on the other hand, has strengthened the intensity of whole parts greatly, switching performance is also strengthened, and significantly improve working life.
Description of drawings
The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a main TV structure cross-sectional schematic of the present utility model
Wherein reference character 1 is that nut body 2 is that riveting end face 3 is that attachment hole 4 is that nut 5 is that tapped hole 6 is that maintenance section 7 is discharge holes
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Preferred embodiment
Rivet coating nut as shown in Figure 1, the nut body 1 that comprises the handstand cup-like structure, its bottom end opening, be connected with ring-type riveting end face 2 on the side of bottom, the top offers attachment hole 3, also comprise a nut 4, nut 4 is positioned at the inner tip of nut body 1, the tapped hole 5 of nut 4 and the position correspondence of attachment hole 3.
The internal side wall of the size of described nut 4 and nut body 1 is complementary, and the cylindrical sidewall of nut 4 closely contacts with the internal side wall of nut body 1 and is connected.
The periphery of top, the top attachment hole 3 of nut body 1 is connected with a hollow tube-shape maintenance section 6.
Also comprise a plurality of discharge holes 7, discharge hole 7 is positioned on the sidewall of nut body 1 and the nut body 1 of riveting end face 2 connection parts.
The bottom of described nut 4 is higher than the horizontal position at riveting end face 2 places.
By nut body 1 is being set to hollow-core construction, and the connection force part of portion is provided with a nut 4 within it, when having reduced the material of producing, its strength character also is improved, and the length of nut 4 can be regulated as required, and is changeable, and nut 4 can be directly embedded into the inner tip of nut body 1, because the size coupling can closely be fixed; In addition, maintenance section 6 is set, more convenient in the time of use.
Disclosed all features in this specification except mutually exclusive feature, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
