One goes out oil draining boltTechnical field
The present invention relates to a kind of bolt, particularly one goes out oil draining bolt, belongs to machanical fastener technical field.
Background technique
Bolt is by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, for being fastenedly connected two mechanical machine part with through hole.This Connecting format claims bolt to connect, and it is belong to removably connect that bolt connects.But in present enterprise, owing to lacking the maintaining regularly to machinery, simultaneously under the impact of the factors such as humid environment, bolt can be caused to become rusty dead, cause bolt to unload to get off, cause unnecessary trouble, affect working efficiency, delay the normal operation of machinery.
As Chinese invention patent " a kind of Novel bolt ", application number is 201120460551.8, disclose a kind of Novel bolt, after there is the dead phenomenon of rust in this bolt, oil gun plug is used to inject lubricant oil in oiling groove, lubricant oil will ooze out from oil outlet, and the connecting part of lubrication screw rod and mechanical parts, can unload so fast.After the dead phenomenon of rust occurs this bolt, need to use oil gun to inject lubricant oil in oiling groove, more loaded down with trivial details, oiling efficiency is slow; The specification of oil gun must match with the pore size of oiling groove, if size not timing, oil outlet can be caused not go out lubricant oil or lubricant oil spills, make the bolt of often kind of specification need to join an oil gun or oil gun connecting head, user cost is large.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of easy to use and user cost low go out oil draining bolt.
Technical solution of the present invention is achieved in that one goes out oil draining bolt, comprises bolt body, and described bolt body is formed by connecting by bolt head and screw rod, and described inside screw is provided with oil storage tank; Full lubricant oil is established in described oil storage tank; Described screw rod has the oil outlet communicated with oil storage tank; Described oil outlet comprises oil-feed runner and fuel-displaced runner; Described oil-feed runner and fuel-displaced runner communicate; Described fuel-displaced runner is provided with two, and in labyrinth-like; The opening of described oil storage tank is provided with piston; The outer end of described piston is connected with push rod; Described push rod is connected with piston through bolt head; The outer end of described push rod is provided with push-plate.
Preferably, gap is left between described push-plate and bolt head; Rubber ring is provided with in described gap.
Preferably, described piston jacket has seal ring.
Preferably, described screw rod has at least two oil outlets.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Of the present invention go out oil draining bolt, establish full lubricant oil in oil storage tank, when generation rust dead phenomenon after, piston press oil storage tank inner space, lubricant oil will ooze out from oil outlet, the connecting part of lubrication screw rod and mechanical parts, simple to operate, easy to use, fuel-displaced high with lubricating efficiency; Because fuel-displaced runner is provided with two, and in labyrinth-like, can not leak when making lubricant oil be stored in oil storage tank, ensure that the lubrication effect of lubricant oil during use; Need not be bolt configuration oil gun or the oil gun connecting head of different size specially, greatly reduce user cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 be of the present invention go out the structural representation of oil draining bolt;
Accompanying drawing 2 be of the present invention go out the using state schematic diagram of oil draining bolt;
Wherein: 1, bolt head; 2, screw rod; 3, oil storage tank; 4, oil-feed runner; 5, fuel-displaced runner; 6, piston; 7, push rod; 8, push-plate; 9, rubber ring; 10, seal ring; 11, mechanical parts.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
One of the present invention as shown in Figure 1 goes out oil draining bolt, comprises bolt body, and described bolt body is formed by connecting by bolt head 1 and screw rod 2, and described screw rod 2 inside is provided with oil storage tank 3; Full lubricant oil is established in described oil storage tank 3; Described screw rod 2 has the oil outlet communicated with oil storage tank 3; Described oil outlet comprises oil-feed runner 4 and fuel-displaced runner 5; Described oil-feed runner 4 and fuel-displaced runner 5 communicate; Described fuel-displaced runner 4 is provided with two, and in labyrinth-like; The opening of described oil storage tank 3 is provided with piston 6; The outer end of described piston 6 is connected with push rod 7; Described push rod 7 is connected with piston 5 through bolt head 1; The outer end of described push rod is provided with push-plate 8; In order to prevent push-plate 8 to be at ordinary times pushed by unexpected touching, leaving gap between described push-plate 8 and bolt head 1, in described gap, being provided with rubber ring 9; In order to increase sealing between piston 5 and oil storage tank 3, described piston 5 overcoat has seal ring 10.
One of the present invention as shown in Figure 2 goes out oil draining bolt, when bolt occur occur rust dead phenomenon twist motionless after, take off rubber ring 9, promote push-plate 8, piston 5 is driven to extrude oil storage tank 3 inner space, lubricant oil will ooze out through oil-feed runner 4 and fuel-displaced runner 5, the connecting part of lubrication screw rod 2 and mechanical parts 11, bolt so just can be made to be turned, because the connecting part of screw rod 2 and mechanical parts 11 is lubricated, bolt can be backed out fast, reduce unnecessary dead time, add the working efficiency of machinery; Of the present invention go out oil draining bolt, simple to operate, easy to use, fuel-displaced and lubricating efficiency is high; Because fuel-displaced runner is provided with two, and in labyrinth-like, can not leak when making lubricant oil be stored in oil storage tank, ensure that the lubrication effect of lubricant oil during use; Need not be bolt configuration oil gun or the oil gun connecting head of different size specially, greatly reduce user cost.
Above-mentioned goes out oil draining bolt, described screw rod has at least two oil outlets, the connecting part of guarantee lubricant oil sufficient lubrication screw rod and mechanical parts.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
