Abstract
The utility model discloses a screw protective cap which comprises a cap body which is a rubber sleeve. A sealing ring and a magnetic ring are inlaid from the internal to the external on the bottom of the rubber sleeve. When the screw protective cap is in use, the rubber sleeve is sleeved over the screw so that the permanent magnetic ring is attached to a nut to prevent dropping off of the rubber sleeve. With a sealing ring, the rubber sleeve is dustproof and anticorrosion, thereby protecting the screw. The screw protective cap is reasonable in design, and simple in structure, and effectively prevents screw threads from being contaminated or rusted.
Description
Technical field
The utility model relates to a kind of screw rod protective cap.
Background technique
At present; the application of screw is ubiquitous, but screw in use also exists defect, such as getting rusty easily; screw thread becomes easily infected by dirt and makes nut be difficult to dismounting etc., prevents that nut from getting rusty and being infected with the protecting jacket of dirt so we are badly in need of designing a kind of being specifically designed to.
Summary of the invention
For overcome screw thread become easily infected by dirt make nut be difficult to dismounting problem, the utility model provides a kind of screw rod protective cap, effectively preventing dust corrode.
The utility model overcomes the above problems and the technological scheme that adopts is: a kind of screw rod protective cap, comprise cap body, and cap body is rubber sleeve, is inlaid with successively from inside to outside seal ring and magnet ring on described rubber sleeve bottom surface.
When use, described rubber sleeve is enclosed within on screw rod, permanent magnet magnetic iron hoop is adsorbed on nut, prevent that rubber sleeve from coming off; Described rubber sleeve has again the effect of preventing dust corrosion by installing seal ring additional, and then has protected screw rod.The utility model is reasonable in design, simple in structure, can effectively prevent that screw thread is infected with dirt or gets rusty.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model.
Embodiment
A kind of screw rod protective cap, as shown in Figure 1, comprises cap body 3, and cap body 3 is rubber sleeve, is inlaid with successively from inside to outside seal ring 5 and magnet ring 1 on described rubber sleeve bottom surface.When use, described rubber sleeve is enclosed within on screw rod 2, permanent magnet magnetic iron hoop is adsorbed on nut 4, prevent that rubber sleeve from coming off; Described rubber sleeve has again the effect of preventing dust corrosion by installing seal ring 5 additional, and then has protected screw rod.
