A kind of antirust screw that is provided with the oil storage inner chamber
Technical field
The invention provides a kind of screw, particularly relate to a kind of screw with rust inhibition, belong to the hardware technical field.
Background technique
Screw is industrial necessity indispensable in daily life: as the minimum screw of the uses such as photographic camera, glasses, clock and watch, electronics; Screw as one of TV, electric product, musical instrument, furniture etc.; Use large-scale screw, nut as for engineering, building, bridge; Traffic tool, aircraft, electric car, automobile etc. are large primary screw and use.Screw is in the industrial vital task of bearing, as long as exist industry on the earth, the function of screw is forever important.
Although be a slight screw, once dismounting does not fall to allow the people have a headache, because can often affect process and the time of whole maintenance.
The screw cause analysis of getting rusty: 1. Electroplate Factory, when electroplating the five metals screw, does not dry and does not dry, and causes steam remaining.Or when packing, there is condensed water to form after drying.Cause chemical reaction, produce bad generation, cause the five metals screw to get rusty.2. in wet damp place, deposit for a long time, of long duration, five metals screw just being corroded slowly, oxidized, cause serious getting rusty.3. while electroplating the five metals screw, poor plating, the too a surname of electrodeposited coating plating.Cause getting rusty.Generally speaking, go to analyze reason from four aspects.This four direction is exactly: 1. storage condition 2. is electroplated kind 3. preserving type 4. Environmental Conditions.
Generally, need to be protected the screw pull bar brush rust preventive lubricating oil got rusty, but this method inconvenience very.
Summary of the invention
The objective of the invention is: a kind of easy antirust screw is provided, makes screw convenient in installation and removal, the technological scheme of employing is:
A kind of antirust screw that is provided with the oil storage inner chamber, include screw end and screw body, and the inside of screw body is cavity, and the outer wall of screw body is provided with opening, has lubricant oil in cavity.
Screw is in the process of installation and removal, and the lubricant oil of body interior can slowly overflow, and has guaranteed the lubricated and isolated space on the attachment face, prevents from getting rusty, and makes dismounting more convenient.
As the present invention, further improve, the position of opening is on the wall between screw thread.Like this, when offering opening, need on screw thread, do not offered, make the processing of screw more convenient.
Further improve as the present invention, also be embedded with the sleeve pipe of hollow in the inner chamber of screw body, sleeve pipe can be transferred to.Sleeve pipe can make lubrication oil seal close in wherein, when needs are used, can transfer to sleeve pipe, makes lubricant oil and open communication, prevents the loss that lubricant oil is unnecessary.
As the present invention, further improve, the top of screw body also is provided with pressing component.By pressing pressing component, can make lubricant oil overflow when needed, using effect is better.
technique effect
Antirust screw provided by the invention, utilized the screw body of offering hollow, can make lubricant oil penetrate into better installation interface, completely cut off air, prevents that screw from getting rusty, and can lubricate connected element, makes the installation and removal of screw more convenient.

Embodiment
Embodiment 1
As depicted in figs. 1 and 2, a kind of antirust screw that is provided with the oil storage inner chamber, include screw end 1 and screw body 2, and the inside of screw body 2 is cavity, and the outer wall of screw body 2 is provided with opening 3, has lubricant oil in cavity.The position of opening 3 is on the wall between screw thread.
Screw is in the process of installation and removal, and the lubricant oil of body interior can slowly overflow, and has guaranteed the lubricated and isolated space on the attachment face, prevents from getting rusty, and makes dismounting more convenient.The position of opening 3 is on the wall between screw thread, need on screw thread, not offered, and makes the processing of screw more convenient.
Embodiment 2
As shown in Figure 3, a kind of antirust screw that is provided with the oil storage inner chamber is with embodiment 1 difference: also be embedded with the sleeve pipe 4 of hollow in the inner chamber of screw body 2, sleeve pipe 4 can be transferred to.Sleeve pipe 4 can make lubrication oil seal close in wherein, when needs are used, can transfer to sleeve pipe 4, and lubricant oil is communicated with opening 3, prevents the loss that lubricant oil is unnecessary.
Embodiment 3
As shown in Figure 4, a kind of antirust screw that is provided with the oil storage inner chamber, with embodiment 1 difference, be: the top of screw body 2 also is provided with pressing component 5.By pressing pressing component 5, can make lubricant oil overflow when needed, using effect is better.
