Abstract
The utility model discloses a hexagonal screw head screw convenient for the whole screw head to enter a wood board, which consists of a screw head and a screw rod connected with the screw head, wherein the screw head is provided with a plurality of scraping ribs facing the side of the screw rod and along the circumference of the screw rod; the scraping rib is a cone which protrudes out of the screw head body and has a triangular cross section, and the screw head, the screw rod and the scraping rib are of an integrated structure; the center of the end face of the screw, far away from the screw head, is of an invaginated hexagonal structure. The utility model discloses need not be with the help of other instrument of punching during the use, alright in order to accomplish the tapping, punch, the process of hollowing out, simple and convenient has improved work efficiency, has reduced the unnecessary power consumption.
Description
Technical Field
The utility model belongs to container timber apron installation field, concretely relates to hexagon screw head screw convenient to whole entering plank of screw head.
Background
Present timber apron is installed to container body's base on, need run through timber apron and floorbar through boring the hole scraping device earlier, the timber apron screw that will take the tapping afterwards carries out the tapping and twists in the through-hole of the floorbar of timber apron and container body and lock, the step is loaded down with trivial details, the station and the cost of labor of production water line have been increased, at the steel construction, electronic apparatus, mechanical equipment field does not have this kind of national standard screw thread self-drilling tapping screw at present, need punch earlier the back tapping and screw again with the screw and screw.
Disclosure of Invention
The purpose of the invention is as follows: an object of the utility model is to provide a hexagonal screw head screw convenient to whole entering plank of screw head to prior art not enough.
The technical scheme is as follows: in order to achieve the above object, the present invention is specifically accomplished by: a hexagonal screw head screw convenient for a screw head to integrally enter a wood board is composed of a screw head and a screw rod connected with the screw head, wherein the screw head faces the side of the screw rod and is provided with a plurality of scraping ribs along the circumference of the screw rod; the scraping rib is a cone which protrudes out of the screw head body and has a triangular cross section, and the screw head, the screw rod and the scraping rib are of an integrated structure; the center of the end face of the screw, far away from the screw head, is of an invaginated hexagonal structure.
Wherein, there is the contact point all in scraping muscle bottom and screw rod periphery and screw head periphery, and it has and only one contact point with screw head periphery.
Wherein, the interval between the adjacent scraping rib and the connection point of screw head periphery equals.
Wherein, the same both ends that scrape the muscle and link to each other with screw head, screw rod respectively are highly different, and scrape the muscle and link to each other the end with the screw rod and be higher than scraping the muscle and link to each other the end with the screw head.
Wherein, the surface of scraping muscle is personally submitted 30 contained angles with the screw head place.
The outer surface of the screw head is provided with a counter bore with a regular hexagonal structure, and the distance from the center of the counter bore to the surface of the screw head is smaller than the distance from the periphery of the counter bore to the surface of the screw head.
Has the advantages that: compared with the prior art, the utility model, there are following advantage:
(1) the utility model has simple structure and scientific design, and can form a counter bore which can accommodate the screw head by rotationally punching on the board through the scraping rib when the screw rotates on the board by designing the scraping rib at the bottom of the screw head;
(2) the utility model can drill the counter bore for accommodating the screw head on the wood board through the self structural design, so that the screw can enter or penetrate the wood board as a whole, and the screw head is prevented from being exposed outside the wood board to influence the installation or use;
(3) when the utility model is used, the processes of tapping, punching and hollowing can be finished without the help of other punching tools, thus being simple and convenient, improving the working efficiency and reducing unnecessary energy consumption;
(4) the utility model discloses can be fit for the use of hexagon screw instrument, can better improve the degree of agreeing with of instrument and screw.
