Abstract
The utility model relates to an improve bolt of lubricated effect, include threaded body and install the hexagon head of threaded body's tip, the intermediate position of the up end of hexagon head is opened there is " ten " word groove, the oilhole has been seted up downwards perpendicularly to the bottom surface in " ten " word groove, and this oilhole runs through the hexagon head and extends to threaded body, and the bottom of oilhole is equipped with two water conservancy diversion holes, the water conservancy diversion hole is the inclined hole to extend to threaded body's outer end. The utility model has the advantages of simple structure and reasonable design, through setting up " ten " word groove, be convenient for screw up or the loose bolt that unloads, through setting up oilhole and water conservancy diversion hole, twist owing to get rusty when the bolt when not getting off, to injecting lubricating oil in the oilhole into, lubricating oil just so can be convenient for back out the bolt on threaded body is injected into in the water conservancy diversion hole.
Description
Technical field
The utility model relates to a kind of bolt, particularly relates to a kind of bolt improving lubrication effect.
Background technique
Bolt is a kind of fastening piece the most frequently used in productive life; but when carrying out connecting of workpiece with bolt; often there will be such a case: due to long-time use; the situation occurring corrosion between the thread section of bolt and tapped hole can be caused; no matter during such spanner unthread bolts, can compare effort, be to bolt or bolt hole simultaneously; damage to a certain degree can be caused, affect its working life.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of bolt improving lubrication effect.
The utility model is achieved through the following technical solutions:
A kind of bolt improving lubrication effect, comprise threaded body and be arranged on the hexagon head of end of described threaded body, the neutral position of the upper-end surface of described hexagon head has " ten " word groove, the bottom surface of described " ten " word groove offers oilhole downward vertically, this oilhole runs through hexagon head and extends to threaded body, the bottom of oilhole is provided with two pod apertures, and described pod apertures is inclined hole, and extends to the outer end of threaded body.
As optimal technical scheme of the present utility model, the degree of depth of described " ten " word groove is 1/3rd of hexagon head thickness.
As optimal technical scheme of the present utility model, the cross section of described pod apertures is rounded.
As optimal technical scheme of the present utility model, the angle of the shaft axis between described two pod apertures is 60 degree.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by arranging " ten " word groove, are convenient to tighten or loose unloading bolt; By arranging oilhole and pod apertures, when bolt owing to getting rusty twist not get off time, in oilhole, inject lubricant oil, lubricant oil is injected on threaded body through pod apertures, this makes it possible to be convenient to bolt to screw down.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is plan view of the present utility model.
In figure: 1 ?threaded body; 2 ?hexagon head; 3 ?" ten " word groove; 4 ?oilhole; 5 ?pod apertures.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Fig. 1 is plan view of the present utility model, and Fig. 2 is plan view of the present utility model.
Described a kind of bolt improving lubrication effect, comprise threaded body 1 and be arranged on the hexagon head 2 of end of described threaded body 1, the neutral position of the upper-end surface of described hexagon head 2 has " ten " word groove 3, the bottom surface of described " ten " word groove 3 offers oilhole 4 downward vertically, this oilhole 4 runs through hexagon head 2 and extends to threaded body 1, the bottom of oilhole 4 is provided with two pod apertures 5, and described pod apertures 5 is inclined hole, and extends to the outer end of threaded body 1.
The degree of depth of described " ten " word groove 3 is 1/3rd of hexagon head 2 thickness; The cross section of described pod apertures 5 is rounded, and the angle of the shaft axis between described two pod apertures 5 is 60 degree.
The utility model structure is simple, reasonable in design, by arranging " ten " word groove, is convenient to tighten or loose unloading bolt; By arranging oilhole and pod apertures, when bolt owing to getting rusty twist not get off time, in oilhole, inject lubricant oil, lubricant oil is injected on threaded body through pod apertures, this makes it possible to be convenient to bolt to screw down.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
