CN105569793A - Exhaust pipe suspension lifting hook - Google Patents

Abstract

The invention relates to an automobile part, in particular to an exhaust pipe suspension lifting hook. The exhaust pipe suspension lifting hook comprises an exhaust pipe, a clamping ring and supporting boards. The exhaust pipe is clamped in the clamping ring. The supporting boards are arranged at the two ends of the clamping ring. The exhaust pipe is fixed to the bottom of an automobile body through the supporting boards and the clamping ring. The clamping ring and the supporting boards are subjected to anti-corrosion treatment, so that protective films are formed on the surfaces of the clamping ring and the supporting boards. By the adoption of the exhaust pipe suspension lifting hook, a connecting structure is firm, and use and maintenance are convenient. The clamping ring and the supporting boards are subjected to anti-corrosion treatment, so that the corrosion resistance of the clamping ring and the supporting boards is remarkably improved.

Description

A kind of outlet pipe hangs suspension hook

Technical field

The present invention relates to a kind of auto parts and components, specifically relate to a kind of outlet pipe and hang suspension hook.

Background technique

In prior art, fixing of automobile exhaust pipe, normally adopts welding manner to connect, easily causes the defects such as inconvenient maintenance.Ling You partial automobile producer makes improvements, and has changed demountable suspension hook, and but, the corrosion resistance of these suspension hooks is very poor, and working life is very short.

Summary of the invention

For the above-mentioned problems in the prior art, the invention provides a kind of outlet pipe and hang suspension hook.

The technical solution used in the present invention is as follows:

A kind of outlet pipe hangs suspension hook, and comprise outlet pipe, snap ring and dunnage, described outlet pipe is stuck in snap ring, and described dunnage is placed in the two ends of snap ring, by dunnage and snap ring, outlet pipe is fixed on vehicle bottom;

Described snap ring and dunnage all form protective film by anti-corrosion treatment on its surface, and processing technology is:

Step 1., on snap ring brushing anti-corrosion foundation liquid, anti-corrosion foundation liquid is mixed by 20 parts of polyvinyl acetate emulsions, 20 parts of diethanol amine, 10 parts of glycerine, 5 parts of watery hydrochloric acid, 0.5 part of anthocyanins, 10 parts of potassium carbonate and 80 parts of water;

2., in collar surface employing ion implantation mode step injects the insoluble network layers altogether that basic zirconium phosphate, silica, chromic acid chromium and prodan formation thickness is 100nm;

3., again step forms metal oxide layer in insoluble network layers altogether;

Step is coated with the priming paint that thickness is 100nm 4., again on metal oxide layer.

Outlet pipe of the present invention hangs suspension hook, and linkage structure is firm, and use and maintenance is convenient.By anti-corrosion treatment snap ring and dunnage, its decay resistance is significantly improved.

Accompanying drawing explanation

Invention to be further described below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that.

Fig. 1 is structural representation of the present invention.

Embodiment

Refer to Fig. 1, a kind of outlet pipe hangs suspension hook, and comprise outlet pipe 1, snap ring 2 and dunnage 3, described outlet pipe 1 is stuck in snap ring 2, and described dunnage 3 is placed in the two ends of snap ring 2, by dunnage 3 and snap ring 2, outlet pipe 1 is fixed on vehicle bottom.

Described snap ring 2 and dunnage 3 all form protective film by anti-corrosion treatment on its surface, and processing technology is:

Step 1., on snap ring brushing anti-corrosion foundation liquid, anti-corrosion foundation liquid is mixed by 20 parts of polyvinyl acetate emulsions, 20 parts of diethanol amine, 10 parts of glycerine, 5 parts of watery hydrochloric acid, 0.5 part of anthocyanins, 10 parts of potassium carbonate and 80 parts of water;

2., in collar surface employing ion implantation mode step injects the insoluble network layers altogether that basic zirconium phosphate, silica, chromic acid chromium and prodan formation thickness is 100nm;

3., again step forms metal oxide layer in insoluble network layers altogether;

Step is coated with the priming paint that thickness is 100nm 4., again on metal oxide layer.

Above content is only to structure example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
