Abstract
The utility model provides a kind of bolt, belongs to field of mechanical technique.It solve the problem that existing bolt easily gets rusty.This bolt comprises the head and shank that are connected as a single entity, shank offers outside thread, at head, place offers counterbore, at counterbore place, blocking has plug, shank offers oilhole and oilhole communicates with counterbore along axis direction, the sidewall of shank is offered in axial direction has some equally distributed oil grooves and oil groove is communicated by oil duct with oilhole, and the sidewall that the bottom two of shank is relative all offers breach, is provided with some hairbrush and the outer end of hairbrush slightly exceeds shank sidewall in breach.The utility model has the advantage of not easily getting rusty.
Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of bolt.
Background technique
Bolt daily life when in and in panel beating and machine tooling technical field in the middle of, be absolutely necessary, but in moister, the metal object that bolt is connected with it holds and gets rusty very much, now in Bolt dismantling, just have very burden, namely bolt is difficult to take apart from the tapped hole of raw full rusty stain.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of bolt not easily got rusty.
The purpose of this utility model realizes by following technical proposal: a kind of bolt, comprise the head and shank that are connected as a single entity, shank offers outside thread, it is characterized in that, at head, place offers counterbore, at counterbore place, blocking has plug, shank offers oilhole and oilhole communicates with counterbore along axis direction, the sidewall of shank is offered in axial direction has some equally distributed oil grooves and oil groove is communicated by oil duct with oilhole, the sidewall that the bottom two of shank is relative all offers breach, some hairbrush are provided with and the outer end of hairbrush slightly exceeds shank sidewall in breach.
Compared with prior art, the utility model offers by bolt shank be connected oilhole and oil groove, lubricant oil is poured into from head counterbore, lubricant oil flows into oil groove from oilhole, thus when bolt is mounted on equipment, surface of contact between bolt and its metal object connected has remained lubricant oil, avoid bolt get rusty and be difficult to dismantle problem, simultaneously, by being arranged on the hairbrush of shank base both sides, the dust at the screw thread place accumulated on the metal object matched and grease are disposed by bolt in the process of twisting, thus do not need to clear up in addition, easy to use, cleaning effect is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional structure schematic diagram of the present utility model.
In figure, 1, head; 11, counterbore; 2, shank; 21, oilhole; 22, oil duct; 23, oil groove; 24, breach; 3, hairbrush; 4, plug.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this bolt comprises the head 1 and shank 2 that are connected as a single entity, shank 2 offers outside thread, counterbore 11 is offered in head 1 end, at counterbore 11 place, blocking has plug 4, shank 2 offers oilhole 21 and oilhole 21 communicates with counterbore 11 along axis direction, the sidewall of shank 2 is offered in axial direction has some equally distributed oil grooves 23 and oil groove 23 is communicated by oil duct 22 with oilhole 21, the sidewall that the bottom two of shank 2 is relative all offers breach 24, is provided with some hairbrush 3 in breach 24 and the outer end of hairbrush 3 slightly exceeds shank 2 sidewall.
Be connected oilhole 21 and oil groove 23 is offered by bolt shank 2, lubricant oil is poured into from head 1 counterbore 11, lubricant oil flows into oil groove 23 from oilhole 21, thus when bolt is mounted on equipment, surface of contact between bolt and its metal object connected has remained lubricant oil, avoid bolt get rusty and be difficult to dismantle problem, simultaneously, by being arranged on the hairbrush 3 of shank 2 two bottom sides, the dust at the screw thread place accumulated on the metal object matched and grease are disposed by bolt in the process of twisting, thus do not need to clear up in addition, easy to use, cleaning effect is better, and when not needing charging-up lubricant oil, by plug 4 by clogging for counterbore 11, so just, extraneous impurity and rainwater can be prevented by oil duct 22 to be mixed into the problem causing bolt to get rusty to bolt inside.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
