Abstract
The invention discloses a bolt with oil discharge and oil return functions. The bolt comprises a bolt body formed by connection of a bolt head and a screw. An oil storage slot is formed in the screw and is filled with lubricating oil. Oil outlet holes communicated with the oil storage slot are formed in the screw axially. A piston is arranged at an opening of the oil storage slot. A push rod is connected to the outer end of the piston and penetrates the bolt head to be connected with the piston. A push plate is arranged at the outer end of the push rod. The bolt with the oil discharge and oil return functions has the advantages that the bolt is simple in structure, convenient to use and high in oil discharge and lubrication efficiency; oil injectors or oil injector connectors do not need to be provided for bolts in different specifications specially, so that use cost is reduced greatly; the lubricating oil can be recycled, so that unnecessary waste of the lubricating oil is avoided.
Description
Technical field
The present invention relates to a kind of bolt, particularly a kind of fuel-displaced oil return 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; Lubricant oil can only use by single, and waste is serious.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose one can easy to use, user cost is low and the recuperable fuel-displaced oil return bolt of lubricant oil.
Technical solution of the present invention is achieved in that a kind of fuel-displaced oil return bolt, and comprise bolt body, 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 axially has the oil outlet communicated with oil storage tank; 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 axially has at least two oil outlets.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Fuel-displaced oil return bolt of the present invention, establishes full lubricant oil in oil storage tank, when after the dead phenomenon of generation rust, and 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; Need not be bolt configuration oil gun or the oil gun connecting head of different size specially, greatly reduce user cost; Lubricant oil can be recovered, and avoids the waste of unnecessary lubricant oil.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of fuel-displaced oil return bolt of the present invention;
Accompanying drawing 2 is the using state schematic diagram of fuel-displaced oil return bolt of the present invention;
Wherein: 1, bolt head; 2, screw rod; 3, oil storage tank; 4, oil outlet; 5, piston; 6, push rod; 7, push-plate; 8, rubber ring; 9, seal ring; 10, mechanical parts.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
The fuel-displaced oil return bolt of one of the present invention as shown in Figure 1, 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 axially has the oil outlet 4 communicated with oil storage tank; The opening of described oil storage tank 3 is provided with piston 5; The outer end of described piston 5 is connected with push rod 6; Described push rod 6 is connected with piston 5 through bolt head 1; The outer end of described push rod 6 is provided with push-plate 7; In order to prevent push-plate 7 to be at ordinary times pushed by unexpected touching, leaving gap between described push-plate 7 and bolt head 1, in described gap, being provided with rubber ring 8; In order to increase sealing between piston 5 and oil storage tank 3, described piston 5 overcoat has seal ring 9.
The fuel-displaced oil return bolt of one of the present invention as shown in Figure 2, when bolt occur rust dead phenomenon twist motionless after, take off rubber ring 8, promote push-plate 7, piston 5 is driven to extrude oil storage tank 3 inner space, lubricant oil will ooze out from oil outlet 4, the connecting part of lubrication screw rod 2 and mechanical parts 10, bolt so just can be made to be turned, now, can to pull back push-plate 7, piston 5 is driven to be pulled, oil storage tank 5 inner space becomes large, the Excess lubricating oil of the connecting part of screw rod 2 and mechanical parts 10 can be drawn back from oil outlet 4, be stored in oil storage tank 3, so that next time uses, avoid the waste of unnecessary lubricant oil, add the continuous usability of this bolt, because the connecting part of screw rod 2 and mechanical parts 10 is lubricated, bolt can be backed out fast, reduce unnecessary dead time, add the working efficiency of machinery, fuel-displaced oil return bolt of the present invention, simple to operate, easy to use, fuel-displaced high with lubricating efficiency, need not be bolt configuration oil gun or the oil gun connecting head of different size specially, greatly reduce user cost.
Above-mentioned fuel-displaced oil return bolt, described screw rod axially 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.
