Abstract
The screw comprises a screw cap, wherein a cutting edge extending from the middle of the screw cap to the edge of the screw cap is arranged on the bottom surface of the screw cap. According to the invention, the cutting edge is arranged on the bottom surface of the nut, when the screw is arranged on a metal plate, paint on the surface of the metal plate can be removed by the cutting edge in the high-speed rotation process of the screw, so that the screw can be effectively contacted with the metal plate.
Description
Technical field
The present invention relates to technical field of fastening, more particularly, it relates to a kind of screw.
Background technology
Existing air-conditioning fixes typically by screw for the panel beating sprayed paint, and is painted isolation, it does not have effectively contact bottom nut 100 and between panel beating, it is impossible to ensure the seriality of the reliable ground of air-conditioning entirety.
Therefore, how to ensure effectively to contact between screw with panel beating, become the technical problem that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention
In view of this, first purpose of the present invention is in that to provide a kind of screw, to realize effectively contacting between screw with panel beating.
For achieving the above object, the present invention provides following technical scheme:
A kind of screw, including nut, the bottom surface of described nut is provided with the cutting edge extended from the middle part of described nut to the edge of described nut.
Preferably, in above-mentioned screw, described cutting edge and described nut are integral type structure.
Preferably, in above-mentioned screw, the cutting of described cutting edge is towards the inclined bottom surface of described nut.
Preferably, in above-mentioned screw, described cutting edge prolongs camber line and extends from the middle part of described nut to the edge of described nut.
Preferably, in above-mentioned screw, described cutting edge broadens to the edge of described nut gradually from the middle part of described nut.
Preferably, in above-mentioned screw, the quantity of described cutting edge is multiple.
Preferably, in above-mentioned screw, multiple described cutting edges are arranged clockwise.
Preferably, in above-mentioned screw, multiple described cutting edges are evenly arranged in the bottom surface of described nut.
Can be seen that from above-mentioned technical scheme, nut bottom surface in the present invention is provided with cutting edge, when adopting this kind of screw to be arranged on panel beating, in screw high-speed rotation, the paint on panel beating surface can be removed by cutting edge, therefore, it is possible to make screw effectively contact with panel beating, it is ensured that the seriality of the reliable ground that air-conditioning is overall.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
The side-looking structural representation of the screw that Fig. 1 provides for the embodiment of the present invention；
The screw that Fig. 2 provides for the embodiment of the present invention look up structural representation.
Wherein, 100 be nut, 101 be cutting edge, 1011 for facet.
Detailed description of the invention
The core of the present invention is in that to provide a kind of screw, to realize effectively contacting between screw with panel beating.
Hereinafter, with reference to accompanying drawing, embodiment is illustrated.Additionally, the summary of the invention described in claim is not played any restriction effect by embodiments illustrated below.It addition, the full content of the composition represented by example below is not limited to necessary to the solution as the invention described in claim.
Refer to the side-looking structural representation of the screw that Fig. 1 to Fig. 2, Fig. 1 provide for the embodiment of the present invention；The screw that Fig. 2 provides for the embodiment of the present invention look up structural representation.
The screw that the embodiment of the present invention provides includes the bottom surface of 100,100 and is provided with the cutting edge 101 extended from the edge to 100, the middle part of 100.100 bottom surfaces in the present invention are provided with cutting edge 101, when adopting this kind of screw to be arranged on panel beating, in screw high-speed rotation, the paint on panel beating surface can be removed by cutting edge 101, therefore, it is possible to make screw effectively contact with panel beating, it is ensured that the seriality of the reliable ground that air-conditioning is overall.
It should be noted that the cutting edge 101 and 100 in the embodiment of the present invention is integral type structure, certainly, cutting edge 101 can also be welded on 100.Screw can drive cutting edge 101 to move together when rotating fixing.
In order to effectively be wiped off by the paint of screw Yu panel beating matching part, the facet 1011 of cutting edge 101 is to the inclined bottom surface of nut 100.Facet 1011 can be cut lacquer painting and scrape off the paint when nut 100 bottom surface touches lacquer painting.So-called facet 1011 is the face that cutting edge 101 has cutting power, and when screw turns clockwise, it is possible to be arranged on panel beating by screw, the facet 1011 of cutting edge 101 is positioned at the face that cutting edge contacts at first with paint.
Cutting edge 101 prolongs camber line from the edge to 100, the middle part of 100 and extends, and so can pass through rotational automatic clean out the paint scraped after cutting edge 101 scrapes off the paint.
Cutting edge 101 broadens gradually from the edge at the middle part to 100 of 100.Cutting edge 101 is positioned at the position wider width of frontside edge, it is possible to ensures that cutting edge 101 increases and panel beating contact surface effectively after scraping off the paint, guarantees the seriality of overall reliable ground with this.
In the embodiment of the present invention, the quantity of cutting edge 101 is multiple, and multiple cutting edges 101 are evenly arranged in the bottom surface of 100 or adopt nonuniform mutation operator.Uniformity in order to ensure its stress preferentially adopts the form being evenly arranged.
In order to better removed by the paint scraped, multiple cutting edges 101 are arranged clockwise.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
