Abstract
The utility model discloses a kind of wood to mould and furniture special screw, belong to a kind of screw, comprise screw body, also extension is provided with on the downside of the top of described screw body, described extension and screw body perpendicular, the top of described extension is provided with arc surface, and bottom is provided with ledge structure, and the table top that described ledge structure and screw body are installed matches.By the ledge structure arranged below extension, screw can be completed on the sheet material with irregular structures such as step surfaces fixing, the arc surface on top, extension also can avoid causing on sheet material after screw is fixing to have acute angle simultaneously, finished product wood is moulded and in use security incident occurs with furniture, a kind of wood provided by the utility model is moulded with furniture special screw structure simple simultaneously, be suitable for industrialized production, be easy to promote.
Description
Technical field
The utility model relates to a kind of screw, and in particular, the utility model relates generally to a kind of wood and moulds and furniture special screw.
Background technique
At present, the structure of screw general is on the market comparatively single, is not suitable for certain applications occasion, and such as, in Furniture manufacture, the sheet material with step surface then cannot be installed fixing by plain screw, be thus necessary to do further improvement for the structure of conventional screw.
Model utility content
One of the purpose of this utility model is for above-mentioned deficiency, provides a kind of wood to mould and furniture special screw, cannot have step surface, or irregular sheet material carries out the technical problem such as fix to expect to solve conventional screw in prior art.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of wood provided by the utility model is moulded and furniture special screw, comprise screw body, also extension is provided with on the downside of the top of described screw body, described extension and screw body perpendicular, the top of described extension is provided with arc surface, bottom is provided with ledge structure, and the table top that described ledge structure and screw body are installed matches.
As preferably, further technological scheme is: the both sides of described extension centered by the medial axis of screw body symmetrically.
Further technological scheme is: the screw body of bottom, described extension is also provided with outside thread.
Compared with prior art, one of the beneficial effects of the utility model are: by the ledge structure arranged below extension, screw can be completed on the sheet material with irregular structures such as step surfaces fixing, the arc surface on top, extension also can avoid causing on sheet material after screw is fixing to have acute angle simultaneously, finished product wood is moulded and in use security incident occurs with furniture, and use on more easily shoot wood mould the inside, a kind of wood provided by the utility model is moulded with furniture special screw structure simple simultaneously, be suitable for industrialized production, be easy to promote.
Accompanying drawing explanation
Fig. 1 is the structural representation for illustration of the utility model embodiment;
In figure, 1 be screw body, 2 be extension, 21 be arc surface, 22 for ledge structure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in figure 1, an embodiment of the present utility model is that a kind of wood is moulded and furniture special screw, comprise screw body 1, extension 2 is provided with on the downside of the top of this screw body 1, and make extension 2 and screw body 1 perpendicular, again arc surface 21 is set on the top of extension 2, bottom setting table stage structure 22, and the table top that this ledge structure 22 and screw body 1 are installed matches.
In the present embodiment, by the ledge structure 22 arranged below extension 2, screw can be completed on the sheet material with irregular structures such as step surfaces fixing, the arc surface on top, extension also can avoid causing on sheet material after screw is fixing to have acute angle simultaneously, finished product wood is moulded and in use security incident occurs with furniture.
Again in another embodiment of the present utility model, for promoting the stability that screw is installed on sheet material, also the both sides of extension 2 can be set to centered by the medial axis of screw body 1 symmetrical; And with reference to prior art, the screw body 1 of bottom, extension 2 can set up outside thread.
More preferably, also the sectional shape of above-mentioned extension 2 can be set to circle, ellipse and rectangle, install on dissimilar sheet material to meet.
Than that described above, also it should be noted that spoken of in this manual " embodiment ", " another embodiment ", " embodiment " etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
Although be described the utility model with reference to multiple explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and mode of execution, these amendments and mode of execution will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the constituent elements of subject combination layout and/or layout.Except the modification of carrying out constituent elements and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
