Abstract
The invention discloses a castellated head bolt which comprises a screw neck and a screw cap arranged at the upper part of the screw neck, the top of the screw cap is provided with a plurality of rotating teeth which extend in the axial direction of the bolt and drive the bolt to rotate, a tooth gap formed between every two rotating teeth is matched with the head of a screwdriver, and the rotating teeth can be driven to rotate by the rotation of the screwdriver perpendicularly matched with the axial direction of the bolt. By using the invention for connection, the bolt can be rotated without using a spanner, and has the advantages of convenient installation and high efficiency.
Description
Technical field
The present invention relates to a kind of flute profile hook bolt that is applicable in the Furniture panel connection.
Background technique
In furniture industry,, adopt three-in-one fastener or " crescent moon " type four unification fasteners usually as the connection fastener between each constituent elements in the furniture for the ease of installation, transportation and the dismounting of furniture.
These two kinds of connection fasteners all have certain defective.The three-in-one fastener of screw rod has to be installed fast, the characteristics of beautiful shape (only exposing the fastener end) at furniture surface, but little with this connection fastener force bearing point, the furniture soundness of assembling is poor, working life is short, and is unable to undergo to move, and generally moves 1 and will be damaged for twice; Selenodont four unification fasteners are made of screw rod, nut, pad and pre-nut, connect the two boards material by bolt, at first on a sheet material, bore mounting hole, a hole vertical with mounting hole dug at the place at the inner pad of sheet material, screw rod passes pad along hole to another sheet material from a sheet material inside, again with the nut tightening bolt that is embedded in another sheet material hole end, this structure is because pad is to be enclosed within on the screw rod, therefore the hole that digs out is bigger, and one not attractive in appearance two also influences the ability of sheet material bearing load.
Notice of authorization number is CN201041178Y, notice of authorization day is that the Chinese patent literature on March 26th, 2008 discloses a kind of sheet material " U " type pad connection fastener, this connection fastener comprises screw rod, pad, and screw rod top has the spiral shell neck of one section diameter less than middle part spiral shell body; Pad be provided with one with the opening of spiral shell neck diameter coupling, make pad be " U " type structure, described pad is enclosed within Luo Jingchu through open card.This model utility adopts the bolt mode to connect, and structure is firm; Both solve the three-in-one fastener of above-mentioned screw rod and connected not firm problem, solved the big drawback of selenodont pad screw rod perforate again; And owing to adopt filling pad, pad directly inserts the spiral shell neck from the outside, compares from the mode that the pad middle part penetrates with screw rod, and perforate is little, and object is little, reaches stealthy and connects beautiful shape.Because perforate is less, can be consistent with at present comparatively common three-in-one fastener perforate, can directly replace three-in-one fastener.
Such scheme in actual use, because the hole of beating at any one position of plate surface is vertical with the bolt sense of rotation, therefore need use pocket wrench and stretch into the polygonal nut of clamping in the mounting hole, pulling spanner just can make nut rotate, the bolts and nuts of drive in hole tighten, thereby it is firm that the two boards material is connected; So still, there are a lot of problems: on the one hand, need sheet material be connected by spanner ability swivel bolt; On the other hand, in rotary course, spanner is disposable can only to rotate to an angle at most, that is to say bolt is rotated to an angle, and extremely inconvenience is installed, and makes the efficient of installation very low.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of flute profile hook bolt that is applicable in the Furniture panel connection, when adopting the present invention to connect, do not use spanner just can make the bolt rotation, and easy for installation, the efficient height.
The present invention realizes by adopting following technical proposals:
A kind of flute profile hook bolt, the nut that comprises spiral shell neck and spiral shell neck top, it is characterized in that: described nut top is provided with a plurality ofly extends along the bolt axial direction, and the turning gear of drive bolt rotation, the backlash and the screw-driver head that form between per two turning gears are complementary, and drive described turning gear rotation with the perpendicular screw-driver rotation that cooperates of described bolt axial direction.
Described spiral shell neck and nut place dispose bolting pad, bolting pad comprises the U type groove that cooperates with Luo Jingchu, hold the inner chamber of nut and the bearing hole that stretches into for screw-driver, the spiral shell neck is fastened in the described U type groove, nut is fastened in the described inner chamber, bearing hole and inner chamber are communicated with, and the nut top is over against described bearing hole internal thread cutter.
Described turning gear is awl tooth or straight-tooth, and the tooth bottom is flat or has the arrow-shaped or the cylindricality of tapering.
The bottom of described spiral shell neck is the spiral shell body, and spiral shell body bottom is a thread section, and thread section is threaded with embedded nut, and perhaps described thread section is a Thread Forming TF, and perhaps described bolt end is an EXPANSION ANCHOR BOLTS.
Described screw-driver is straight screwdriver or Phillips screwdriver.
Advantage of the present invention shows:
1, because the present invention adopts " on the nut top a plurality of turning gears being set; the backlash and the screw-driver head that form between per two turning gears are complementary; drive described turning gear rotation with the perpendicular screw-driver rotation that cooperates of bolt axial direction " such technological scheme compared with prior art, thoroughly changed the mounting type of bolt in the existing three-in-one fastener, do not need spanner, in the perforate connection of the arbitrary position of plate surface, but the cutter head of screw-driver can mesh with the turning gear on nut top among the present invention, the transmission direction of change power, become the tighten up a screw rotating force of cutter of Vertical direction and be the rotatory force of bolt on the substantially horizontal, and it is easy for installation, the qualification that not can only rotate to an angle at most by original spanner, improve installation efficiency, simplified installation steps; Simultaneously, adopt in such a way after, the outward appearance stealth of the mounting hole that can make, appearance is more attractive in appearance.
2, " spiral shell neck and nut place dispose bolting pad to the present invention's employing; bolting pad comprises the U type groove that cooperates with Luo Jingchu; hold the inner chamber of nut and the bearing hole that stretches into for screw-driver; the spiral shell neck is fastened in the described U type groove; nut is fastened in the described inner chamber; bearing hole and inner chamber are communicated with, the nut top is over against described bearing hole internal thread cutter " such technological scheme; this bolting pad and bolt are combined use, and the hole that bolting pad and plate surface are beaten is complementary, when reality is used; bearing hole plays the positioning action to screw-driver; U type groove blocks the spiral shell neck, and diameter and spiral shell neck are complementary, and inner chamber holds nut; make nut limited in inner chamber; when the rotary screw cutter made the nut rotation, nut was spacing by inner chamber, thereby makes pre-buried nut tightening in thread section and another sheet material.
When 3, the turning gear that adopts of the present invention is for the awl tooth, be convenient to install mutually with another identical bolt, also available dedicated awl tooth head instrument is installed, and is convenient to straight screwdriver when the tooth bottom is flat and also can uses.
4, the present invention is simple in structure, and is novel, has the vast market using value.
