Embodiment 1

[0016] During the implementation of the present invention, the design purpose of the present invention is firstly introduced.

[0017] The molding protective sleeve designed by the present invention is mainly to solve the problems of two aspects:

[0018] (1) Solve the problems that the glue coating process is not easy to implement due to the fluidity of the sealant in the glue coating process, uneven glue coating on bolt heads or nuts, and inconsistent appearance. The molded protective sleeve designed by the present invention mainly plays the role of a mould, ensuring consistent usage of the sealant. The glue coating process can be simplified through the forming protective sleeve, ensuring that the glue is coated on the surface of the bolt head or the nut without flowing randomly.

[0019] (2) The molded protective sleeve has a certain protective effect on the sealant, solving the problem of premature aging of the sealant due to environmental impacts such as sun exposure, wi...

Abstract

The invention discloses a forming protective jacket which comprises a plug and a forming jacket. The plug and the forming jacket are matched with each other so that the bolt head and nut gumming protective operation technology can be simplified, the forming function is achieved, and the shape and thickness of gum on the surface of a bolt head and the surface of a nut are guaranteed. In addition, sealants on the surface of the bolt head and the surface of the nut can be protected to some extent in the subsequent use process, and the service life of the sealants, a bolt, the nut and other standard parts is prolonged.

Description

technical field [0001] The present application relates to the technical field of mechanical equipment, in particular to a molded protective sleeve. Background technique [0002] When vehicles or other mechanical equipment are used in the offshore environment, the electrochemical medium provided by humid air and salt spray will accelerate the corrosion rate of metal parts. In order to slow down this damage rate, many metal parts used on vehicles, especially other The fastening bolts and nuts need special anti-corrosion treatment. At present, the commonly used process for the anti-corrosion treatment of bolts and nuts is: after assembly, apply sealant to the exposed parts of fasteners such as bolt heads and nuts to isolate them from the atmosphere and delay or prevent their corrosion process. Due to the fluidity of the sealant, if the sealant is directly applied to the bolt heads and nuts, the sealant cannot be applied evenly and is not conducive to molding. Contents of the...
