Description
Technical field
The utility model relates to a kind of bolt, and particularly a kind of automatic oil outlet 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 utility model 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.
Model utility content
The utility model object provides that one can use simply, user cost is low and lubricant oil recuperable automatic oil outlet oil return bolt to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automatic oil outlet 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; Cylinder is provided with in described bolt head; The flexible rod end of described cylinder is connected with piston; The outer surface of described bolt head is provided with the switch of control cylinder.
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 utility model compared with prior art has following advantages:
Automatic oil outlet oil return bolt of the present utility model, 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 solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of automatic oil outlet oil return bolt of the present utility model;
Accompanying drawing 2 is the using state schematic diagram of automatic oil outlet oil return bolt of the present utility model;
Wherein: 1, bolt head; 2, screw rod; 3, oil storage tank; 4, oil outlet; 5, piston; 6, push rod; 7, switch; 8, seal ring; 9, mechanical parts.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of automatic oil outlet oil return bolt as shown in Figure 1, comprise bolt body, 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; Cylinder 6 is provided with in described bolt head 1; The flexible rod end of described cylinder 6 is connected with piston 5; The outer surface of described bolt head 1 is provided with the switch 7 of control cylinder; In order to increase sealing between piston 5 and oil storage tank 3, described piston 5 overcoat has seal ring 8.
Described in the utility model a kind of automatic oil outlet oil return bolt as shown in Figure 2, when bolt occur rust dead phenomenon twist motionless after, press switch 7, cylinder 6 starts, the flexible rod of cylinder 6 stretches out, 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 9, bolt so just can be made to be turned, now, if again press switch 7, cylinder 6 is closed, the flexible rod of cylinder 6 shrinks, 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 9 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 9 is lubricated, bolt can be backed out fast, reduce unnecessary dead time, add the working efficiency of machinery, automatic oil outlet oil return bolt of the present utility model, simple to operate, easy to use, as long as Push switch just can realize fuel-displaced and oil return, the mode of mechanization reduces the labor intensity of workman, improves fuel-displaced and 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 automatic oil outlet 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.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
