Abstract
The invention relates to the technical field of firm connecting pieces, in particular to a bolt with a lubricating structure. The bolt with the lubricating structure comprises a bolt head and a screw rod of which one head face is fixed with the bolt head, an oil injection hole extending to the screw rod is opened in the middle of the bolt head along the axial line direction, an oil outlet communicated with the oil injection hole is opened in the radial direction of the screw rod, a groove which hollows towards the screw rod body is opened in the other head face of the screw rod, and a notch extending to the outer wall of the screw rod is opened in the edge of the groove. After the bolt is used for connecting workpieces, through adding lubricating oil to the oil injection hole, the lubricating oil flows out of the oil outlet and permeates slowly along threads of the screw rod, all the threads can be lubricated by the lubricating oil, the surplus lubricating oil enters the groove from the notch to store, and accordingly the bolt can always locate at a lubricating state to avoid rusting and facilitate bolt mounting and dismounting.
Description
Technical field
The present invention relates to fixed connecting piece technical field, be specifically related to a kind of bolt with lubricating structure.
Background technique
Bolt comprises bolt head, has externally threaded screw rod, when assembling, driving bolt rotary, make to realize connection function in screw rod precession workpiece by turn bolt head; In bolt connects workpiece for a long time, can get rusty between bolt and workpiece, thus cause, in unloading process, not easily taking apart between bolt and workpiece, cause the inconvenience of dismounting.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of bolt with lubricating structure, its structure is simple, can lubricate bolt, be convenient to mounting or dismounting.
Realize technological scheme of the present invention as follows:
A kind of bolt with lubricating structure, comprise bolt head, and the screw rod that is fixedly installed of end face and bolt head, the oil hole extending to screw rod is offered in bolt head central axis direction, the oil outlet be communicated with oil hole is offered in screw rod radial direction, the other end of described screw rod offers the groove to screw body depression, the edge of groove has the notch extending to screw rod outer wall.
Described oil hole, oil outlet are circular port, and oil hole diameter is greater than oil outlet diameter.
In order to make the whole screw thread on oil lubrication screw rod, the outlet end of described oil outlet is on screw rod between screw thread and bolt head.
Have employed such scheme, after bolt connects workpiece, by adding lubricant oil in oil hole, lubricant oil flows out from oil outlet, and slowly permeates along screw flight, makes whole screw thread all can be subject to the lubrication of lubricant oil, unnecessary lubricant oil enters groove from notch and stores, thus can ensure that bolt is in lubricating status always, in order to avoid get rusty, be convenient to the mounting or dismounting of bolt.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 1, a kind of bolt with lubricating structure, comprise bolt head 1, and the screw rod 2 that is fixedly installed of end face and bolt head, the oil hole 3 extending to screw rod is offered in bolt head central axis direction, offer in screw rod radial direction the oil outlet 4 be communicated with oil hole, the other end of screw rod offers the groove 5 to screw body depression, the edge of groove has the notch 6 extending to screw rod outer wall.In concrete enforcement, oil hole, oil outlet are circular port, and oil hole diameter is greater than oil outlet diameter.The outlet end of oil outlet is on screw rod between screw thread 7 and bolt head.
Claims (3)
1. one kind has the bolt of lubricating structure, comprise bolt head, and the screw rod that is fixedly installed of end face and bolt head, it is characterized in that, the oil hole extending to screw rod is offered in bolt head central axis direction, offer in screw rod radial direction the oil outlet be communicated with oil hole, the other end of described screw rod offers the groove to screw body depression, the edge of groove has the notch extending to screw rod outer wall.
2. a kind of bolt with lubricating structure according to claim 1, is characterized in that, described oil hole, oil outlet are circular port, and oil hole diameter is greater than oil outlet diameter.
