Abstract
The invention discloses a nut with an oil discharge function. The nut comprises a nut body. A threaded hole is formed in the nut body. An annular oil storage groove is formed in the nut body and is filled with lubricating oil. At least two oil outlet holes are formed in the nut body axially. Each oil outlet hole comprises an oil inlet flow pass and two oil outlet flow passes in the shape of a labyrinth. The oil inlet flow passes are communicated with the oil storage groove. The oil outlet flow passes are communicated with the threaded hole. A piston is arranged at an opening of the oil storage groove. An even number of push rods in ring array arrangement are connected to the outer end of the piston. A push ring is arranged at the outer ends of the push rods. The bolt with the oil discharge function has the advantages that the bolt is simple in structure, convenient to use and high in oil discharge and lubrication efficiency; since each oil outlet hole comprises the two oil outlet flow passes in the shape of the labyrinth, and the lubricating oil is stored in the oil storage groove and is not leaked, so that lubrication effect during use of the lubricating oil is guaranteed.
Description
Technical field
The present invention relates to a kind of nut, particularly a kind of fuel-displaced nut, belongs to machanical fastener technical field.
Background technique
Nut is exactly nut, is used for the part played the role of fastening with bolt or screw rod together with being screwed in, and is widely used in machinery.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 nut ", application number is 201120460564.5, disclose a kind of nut, the bolt be mated when this nut in a humid environment or harmful gas corrode to issue and get rusty after death, corkage I, lubricant oil in circular oil storage tank just can ooze screw rod and the nut connecting part of profit bolt, and nut can be unloaded fast.In use, lubricant oil is screw rod and the nut connecting part that nature flows into bolt to this nut, without any power-assisted action, oil outlet may be caused not go out lubricant oil, fuel-displaced slow with lubricating efficiency.
And for example Chinese invention patent " a kind of hexagon nut ", application number is 201220146248.5, disclose a kind of hexagon nut, the bolt be mated when this nut in a humid environment or harmful gas corrode to issue and get rusty after death, the thawing of the solid lubrication be in oil groove oil can be in a liquid state by heater, ooze screw rod and the nut connecting part of profit bolt, nut can be unloaded fast.Equally, in use, lubricant oil is screw rod and the nut connecting part that nature flows into bolt to this nut, without any power-assisted action, oil outlet may be caused not go out lubricant oil, fuel-displaced slow with lubricating efficiency.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of lubricant oil pressurized and be extruded the fuel-displaced nut oozed out.
Technical solution of the present invention is achieved in that a kind of fuel-displaced nut, comprises nut body, has tapped hole in described nut body, and described nut body inside is provided with annular oil storage tank; Full lubricant oil is established in described oil storage tank; Described nut body axially has at least two oil outlets; Described oil outlet comprises oil-feed runner and fuel-displaced runner; Described oil-feed runner communicates with oil storage tank; Described fuel-displaced runner communicates with tapped hole; 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 annular array is provided with even number; The outer end of described push rod is provided with throw-out collar.
Preferably, gap is left between described throw-out collar and nut body; Rubber ring is provided with in described gap.
Preferably, described piston jacket has seal ring.
Preferably, described push rod is provided with four.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Fuel-displaced nut of the present invention, establishes full lubricant oil in oil storage tank, the bolt be mated when this nut rust occurs after death, piston press oil storage tank inner space, lubricant oil will ooze out from oil outlet, the screw rod of lubrication bolt and nut connecting part, and nut can be removed; 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.
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 nut of the present invention;
Accompanying drawing 2 is the using state schematic diagram of fuel-displaced nut of the present invention;
Wherein: 1, nut body; 2, tapped hole; 3, oil storage tank; 4, oil-feed runner; 5, fuel-displaced runner; 6, piston; 7, push rod; 8, throw-out collar; 9, rubber ring; 10, seal ring; 11, bolt.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
The fuel-displaced nut of one of the present invention as shown in Figure 1, comprises nut body 1, has tapped hole 2 in described nut body 1, and described nut body 1 inside is provided with annular oil storage tank 3; Full lubricant oil is established in described oil storage tank 3; Described nut body 1 axially has at least two oil outlets; Described oil outlet comprises oil-feed runner 4 and fuel-displaced runner 5; Described oil-feed runner 4 communicates with oil storage tank 3; Described fuel-displaced runner 5 communicates with tapped hole 2; Described fuel-displaced runner 5 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 annular array is provided with even number; The outer end of described push rod 7 is provided with throw-out collar 8; In order to prevent throw-out collar 8 to be at ordinary times pushed by unexpected touching, leaving gap between described throw-out collar 8 and nut body 1, in described gap, being provided with rubber ring 9; In order to increase sealing between piston 6 and oil storage tank 3, described piston 6 overcoat has seal ring 10.
