1. The utility model provides a locking leak protection screw, includes the screw body, characterized by: the surface of the screw thread of the screw body is coated with an anti-loose and anti-leakage coating; the anti-loosening and anti-leakage coating is a microcapsule coating layer wrapping epoxy resin, and the microcapsules are broken through extrusion in the screw locking and rotating process, so that the anti-loosening and anti-leakage effects are realized.

2. The locking and leakage-proof screw as claimed in claim 1, wherein: the anti-loose and anti-leakage coating is only coated on the middle area of the screw.

3. A locking and leakage-proof screw as claimed in claim 1 or 2, wherein: the screw is a screw or a bolt.

Technical Field

The invention relates to a screw.

Background

When the existing screw (screw and bolt) is used for fastening, the problem that the screw thread and the fastened piece are loosened and easy to leak exists, and further improvement is needed.

Disclosure of Invention

The invention aims to provide a locking and leakage-proof screw with good locking and leakage-proof effects.

The technical solution of the invention is as follows:

the utility model provides a locking leak protection screw, includes the screw body, characterized by: the surface of the screw thread of the screw body is coated with an anti-loose and anti-leakage coating; the anti-loosening and anti-leakage coating is a microcapsule coating layer wrapping epoxy resin, and the microcapsules are broken through extrusion in the screw locking and rotating process, so that the anti-loosening and anti-leakage effects are realized.

The anti-loose and anti-leakage coating is only coated on the middle area of the screw. The screw is a screw or a bolt.

The invention realizes the functions of looseness prevention and leakage prevention by crushing the microcapsule in the process of locking and turning the screw; the working effect is good, and the use is very convenient.

Drawings

The invention is further illustrated by the following figures and examples.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

A locking and leakage-proof screw comprises a screw body 1, wherein a locking and leakage-proof coating is coated on the surface of a screw thread of the screw body; the anti-loose and anti-leakage coating is a microcapsule coating layer 2 wrapping epoxy resin, and the microcapsules are broken through extrusion in the screw locking and rotating process, so that the anti-loose and anti-leakage effects are realized.

The anti-loose and anti-leakage coating is only coated on the middle area of the screw, and the drilling function of the head is not affected due to the fact that the head is not coated. The screw is a screw or a bolt.

The microcapsule coating for wrapping the epoxy resin can be a coating prepared by taking urea and formaldehyde as wall materials and taking the epoxy resin E51 as core materials or other commercially available materials.
