Abstract

The utility model discloses an inside and outside hexagonal machine wood screw, include: screw body, screw body includes head end, middle -end and end, the middle -end is screw thread vacancy portion, and there is a circular trompil in screw thread vacancy portion, screw thread vacancy portion links to each other the part in echelon with the head end, the head end is equipped with tapered tread, the middle -end with be equipped with cylindrical thread between the end just it is terminal for outer hex bolts and interior hexagonal combine together, in addition, in two ports interpolation magnetism of allen key for it drops can accurate installation when dismantling the screw to target in place and be difficult to in the fastening, and having improved work and having imitated, according to the embodiment of the utility model provides a inside and outside hexagonal machine wood screw have tapered tread at the screw body front end, can conveniently twist into wood, the engineering of being convenient for operation and simple structure easily make.

Description

A kind of internal-external hexagon machine wood screw
Technical field:
The utility model relates to bolt type securing member, and more specifically, the utility model relates to a kind of internal-external hexagon machine wood screw.
Background technology:
Screw, in daily life is worked as and in the middle of industrial production manufacture, be can't do without, and screw is also referred to as the rice of industry. The utilization of visible screw is extensively, and the utilization scope of screw has: electronic product, and engineering goods, digital product, power equipment, dynamo-electric engineering goods, boats and ships, vehicle, hydraulic engineering, even also uses screw in chemical experiment. Anyway be that super many places are useful screw.
Screw is mainly used in the part of a clamp screw pit, and one with being fastenedly connected between the part of through hole, does not need nut to coordinate this type of attachment to be called screw and connects, and also belongs to and removably connects; Also can coordinate with nut, be used for two with being fastenedly connected between the part of through hole, namely modal screw, holding screw is mainly used in fixing two relative positions between part, our proverb is " stopping screw ", and effect is equivalent to the effect of alignment pin.
Generally on wood when fixing machine wood screw, screw front end is tip shape, the screw terminal outside of general screw is round, on cap nut slightly with some anti-skidding screw threads, prevent in stubborn too sliding, need to throw screw into wood inside by the mode impacting, which often can cause screw bending in the process impacting, greatly shorten the service life of screw, screw head, containing magnetic, does not easily drop in installation process, and it is not too convenient to install, and not quick detachable, this causes certain trouble at work progress to workman.
Utility model content:
In order to address the above problem, it is a kind of simple in structure that the utility model provides, feature richness, and bending when effectively preventing screw to impact into wood, and easily dismantle, increase the life-span of its use.
A kind of internal-external hexagon machine wood screw, comprises screw body, and screw body comprises head end, middle-end and end, the short-and-medium circular hole that has, between middle-end and end, be provided with cylindrical thread, between middle-end and front end in echelon, end lateral surface outer-hexagonal structure, terminus inner is interior hexagonal structure.
As preferably, middle-end is screw thread vacancy portion, and screw thread vacancy part has circular hole.
As preferably, head end is provided with tapered tread, and what between middle-end and described head end, become to be sidelong is trapezoidal.
As preferably, end is outer-hexagonal bolt.
As preferably, the side-facing depressions of end outer-hexagonal enters to be regular hexagon.
The beneficial effects of the utility model are:
(1) the utility model is simple and reasonable, a kind of internal-external hexagon machine wood screw, screw body, described screw body comprises head end, middle-end and end, described middle-end is screw thread vacancy portion, and screw vacancy position has circular hole, is convenient in the time there is no spanner, inject in circular hole and form Simple leverage by little instrument, screw is screwed into wood.
(2) place that in the utility model, the middle-end of exterior angle screw is connected with front end in echelon, can effectively reduce like this resistance when end is screwed into wood, the outer hexagon of the outside one-tenth of end, the friction that increases spanner and internal-external hexagon screw in the time using spanner that internal-external hexagon screw is screwed into wood inside, can effectively block afterbody, be difficult for stripped thread; Be restricted at space outerpace, there is no unnecessary place for wrench operated, now we can utilize the interior hexagonal of outer-hexagonal inside that internal-external hexagon screw is screwed in wood, and in utilizing, hexagonal is carried out next step construction working after fixing. The tapered tread of screw head end can conveniently be screwed into wood, is convenient to engineering operation and simple in structure being easy to manufactured.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the interior hexagonal figure of the outer-hexagonal internal structure of the utility model end.
Detailed description of the invention:
For making goal of the invention of the present utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is simple and reasonable, a kind of internal-external hexagon machine wood screw, it is characterized in that, comprise: screw body A, described screw body A comprises head end 7, middle-end 4 and end 2, described middle-end 4 is screw thread vacancy portion, described head end 7 is provided with tapered tread, and between described middle-end 4 and described end 2, being provided with cylindrical thread 3 and described end is hex bolts 2.
This outer-hexagonal machine wood screw has tapered tread 7 at screw body A head end, can conveniently be screwed in wood, be convenient to engineering operation and simple in structure being easy to manufactured, middle-end 4 is 1 of screw thread vacancy, and screw thread vacancy position has circular hole 5, middle-end and head end junction in echelon 6, effectively reduce the resistance producing when end is screwed into wood inside, head end is provided with tapered tread 7, middle-end 4 and described end 2, between be provided with cylindrical thread 13.
As shown in Figure 2,This kindInternal-external hexagon machine wood screw end is outer-hexagonal bolt 2, when this internal-external hexagon machine wood screw is installed, available spanner is screwed into screw nose circle taper thread 7 in wood, if in the situation that space outerpace is restricted, do not have unnecessary place that wrench operated is provided, now we can utilize the interior hexagonal 1 of outer-hexagonal 2 inside, the interior hexagonal 1 of end outer-hexagonal 2 inner recess is containing being magnetic, install in screw process cannot be with hand steered screw in, magnetisable material tightly holds above inner hexagon spanner, prevent from dropping, in utilizing, hex tool is screwed into internal-external hexagon screw in wood, so just solve at screw afterbody surrounding insufficient space, distance situation slightly far away cannot be used the drawback of spanner operation, interior hexagonal 1 magnetisable material of end 2 inside has solved at limited space, cannot be with hand steered installation screw, the situation that causes screw easily to fall, after internal-external hexagon screw is fixing, carry out next step construction working, the tapered tread 7 of screw head end can conveniently be screwed into wood, be convenient to engineering operation and simple in structure being easy to manufactured.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as the technical scheme that can realize on the basis of above-described embodiment without creative work, all should be considered as falling within the scope of the rights protection of the utility model patent.
