Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is described in further detail.
Inventive point of the invention with propose a kind of application in the new connected mode in the fields such as furniture building materials and using should
The instrument of mode.
Screwdriver nut set of the present invention, including screwdriver and nut, the nut are hexagonal socket nut, the spiral shell
Silk knife cutter head is made up of column cap 1 and connection column cap with the neck 2 of screwdriver shaft 3, and the column cap is between the detail of two thick six
Prismatic, the column cap side is made up of six symmetrical sub- sides of outer convex, and the outer sub- side of convex is by six
Bar column cap incline is separated；
Second sub- border 7 and connection first of the column cap incline by the first sub- border 6, connecting neck portion above connection column cap
The 3rd sub- border 8 on the sub- border 7 of border 6 and second constitutes, for apart from a pair of farthest arc inclines, their the 3rd sub- side
The distance between boundary, and the distance between the wherein one sub- border of incline first and another sub- border of incline second with it is described
The internal diameter gap of nut coordinates；
The neck is hexagon gradually thicker from top to bottom, and neck side is by six symmetrical sub- sides of indent arc
Face is constituted, and the sub- side of indent arc is separated by six neck inclines 9, and the most thin place diameter of the neck is not more than spiral shell
0.8 times of female internal diameter.
Fig. 1 and Fig. 2 provide the specific embodiment schematic diagram of the screwdriver and its application, and hexagonal socket nut is a kind of normal
With nut, but the screwdriver matched with hexagonal socket nut is straight six prism, can only realize screw tightness in coaxial direction.This hair
The bright cutter head to screwdriver is improved so that even if screwdriver inclines certain angle and gos deep into hexagonal socket nut, can also be driven
Hexagonal socket nut it is elastic.
As shown in Fig. 2 when column cap stretches into the nut inner groovy 4 of hexagonal socket nut in an inclined manner, because distance is farthest
Every a pair of curved sides rib, wherein the distance between a sub- border of incline first and another sub- border of incline second are and institute
The internal diameter gap for stating nut coordinates, hence in so that column cap is inclined, still two articles the first of incline the sub- borders and the 3rd sub- border with
Each hexagonal boundary fitting of hexagonal socket nut so that the rotation of column cap can drive the rotation of hexagonal socket nut, neck is most thin
Place near column cap, for column cap inclination when hexagonal socket nut side wall provide receiving space, to reach certain angle of inclination,
Neck most carefully locates 0.8 times that diameter is not more than nut internal diameter, typically takes 0.5-0.7 times of nut internal diameter, can substantially meet and incline
Oblique more than 30 degree of angle rotarily drives nut, while neck is retained enough diameters to maintain stronger mechanical strength,
Fractureed when avoiding using.
The present invention can also be as general hexagonal screwdriver, when screwdriver and nut are rotated coaxially, the 3rd sub- border
The distance between coordinate with the inner groovy gap of hexagonal socket nut, drive nut rotation.
The indent trench bottom of the nut can be designed as recessed taper, to groove during so as to avoiding column cap from being tilted into
The scraping of bottom, causes the seamed edge of column cap to be smoothed, and influence is used.
The invention also discloses a kind of coupling assembly, including body 11, be provided with lower deep gouge 12 in the body, it is described under
Deep gouge one end is closed, and the other end is connected with this body side surface by through hole 15, and the coupling assembly also includes may pass through the through hole
Nut 13, the lower deep gouge is without of length no more than 10 centimetres of through hole.
As shown in Figure 3,4, when using, nut can be put into lower deep gouge and passes through hole, in this body side surface and other portions
Default screw connection on part, it is achieved thereby that a kind of concealed side connection, is especially used in relatively thin horizontal stroke for example more long
To the vertical connection of part and longitudinal component.
In the present invention, due to lower deep gouge one end closing and entire length is shorter, larger knot will not be caused to body itself
Structure is destroyed and strength failure, and does not influence the overall appearance of body surface, but also due to lower deep gouge is shorter, is only capable of using conventional
The screwdriver of gang operated, it is clear that be difficult to operate, screwdriver of the typically no length less than 10 centimetres can extend into lower deep gouge, will
Nut is threaded in or out.
Therefore, coupling assembly of the present invention generally needs the screwdriver nut set for coordinating the present invention foregoing, ability
Side connection and time saving and energy saving technique effect are obtained, as shown in figure 3, set nut in through-holes is stretched into by screwdriver 5 is oblique,
Bit rotary screwdriver rotates in and out nut.
The shape of the lower deep gouge can be designed as depth constantly to be reduced towards near through hole one end, and one can be obtained in end
The individual larger section for opening up through hole, it is also thinner to the excavation of body in blind end, preferable mechanical strength is remained, together
When be also convenient for the inclination of screwdriver and stretch into.
In Fig. 4, the specific embodiment shown in 5, the lower deep gouge is semi-cylindrical, the connection group near through hole one end
Part also includes semicircle cushion block 14, and cushion block through hole 16 is provided with the semicircle cushion block, opens up semicircle end and sets semicircle
Shape cushion block can will disperse the stress of lower deep gouge end, it is to avoid body cracking at thinning lower deep gouge.
Previously described is each preferred embodiment of the invention, if the preferred embodiment in each preferred embodiment
It is not substantially contradictory or premised on a certain preferred embodiment, each preferred embodiment can any stack combinations
Use, the design parameter in the embodiment and embodiment merely to clearly state inventor invention verification process, and
It is not used to limit scope of patent protection of the invention, scope of patent protection of the invention is still defined by its claims, all
It is the equivalent structure change made with specification of the invention and accompanying drawing content, similarly should be included in protection model of the invention
In enclosing.
