Abstract
The invention discloses an anti-loose zinc-plating nut which comprises a nut body and an inner thread, wherein the nut body is coated with a layer of non-nitrite environment-friendly water-based antirust agent; a fixing through hole is formed in the edge of the nut body; a zinc-plating lubrication layer is arranged on the surface of the inner thread of the nut body. According to the nut, the zinc-plating lubrication layer is arranged on the surface of the inner thread, so that the nut has an anti-loose effect and overcome the problem that rust is easily formed on the surface of the inner thread; moreover, the nut is fixed to a stud again through the fixing through hole and a pin column so as to prevent safety accidents caused by falloff of the nut and the stud resulted by looseness of the threaded opening between the nut and the stud are prevented.
Description
Technical field
The present invention relates to a kind of fastening piece in machinery equipment, be specifically related to a kind of anti-loose zinc-coated nut.
Background technique
Along with the development of economic technology, yard craft industry is more and more important in carrier, and the application of special fastener on harbour machinery is also more and more extensive.Harbour machinery fastening piece, due to the particularity of its working environment, gets rusty easily, and the harbour machinery fastening piece after getting rusty has caused very large difficulty in the use.Existing nut is being used a period of time mostly easily to become flexible and even come off later.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of have antirust, the nut of Drop-proof.
In order to achieve the above object, technological scheme of the present invention is as follows:
A kind of anti-loose zinc-coated nut, comprise nut body, internal thread, it is characterized in that, nut body is coated with one deck non-nitrous salt environment-friendly type water based anti-rusting agent, on the edge of nut body, be provided with fixed via, the interior threaded surface of upper cap nut body is provided with zinc-plated lubricating layer.
In the present invention, the diameter of described fixed via is 2～5mm.
Compared with the existing technology, it produces effect and shows in the present invention:
One, the surface of internal thread is provided with zinc-plated lubricating layer, makes nut when possessing locking effect, has also overcome the problem that interior threaded surface is easily got rusty;
Two, by fixed via and pin, again nut and double-screw bolt are fixed, prevented that silk thread mouth between nut and double-screw bolt is loosening and cause nut and double-screw bolt to come off, and then cause security incident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Reference character is: 1 is that nut body, 2 is that zinc-plated lubricating layer, 3 is fixed via.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the invention will be further described.
An anti-loose zinc-coated nut, comprises nut body, internal thread, and nut body is coated with one deck non-nitrous salt environment-friendly type water based anti-rusting agent, on the edge of nut body, is provided with fixed via, and the interior threaded surface of upper cap nut body is provided with zinc-plated lubricating layer.
One deck non-nitrous salt environment-friendly type water based anti-rusting agent that first applies of the present invention is provided with zinc-plated lubricating layer again in interior threaded surface, this non-nitrous salt environment-friendly type water based anti-rusting agent be take antirust auxiliary agent that silicate is major ingredient and number of different types carry out composite, the environment-friendly type water based anti-rusting agent of preparation.The present invention is in when work, when bolts and nuts body is tightened mutually, and clamping force and antirust ability when interior threaded surface is provided with zinc-plated lubricating layer and has guaranteed that internal thread is connected with bolt outside thread.Lubricating layer in zinc-plated lubricating layer is comprised of 838 oiling agents, and 838 oiling agents are a kind of soliquids, in interior threaded surface, form clean, bright and clean, dry, tack-free composite lubricating film, have good greasy property.Transparent, bright composite lubricating film does not change internal thread original surface optical property and material property, and environmental protection, harmless to operator.
Claims (2)
1. an anti-loose zinc-coated nut, comprise nut body, internal thread, it is characterized in that, nut body is coated with one deck non-nitrous salt environment-friendly type water based anti-rusting agent, on the edge of nut body, be provided with fixed via, the interior threaded surface of nut body is provided with zinc-plated lubricating layer.
2. anti-loose zinc-coated nut according to claim 1, is characterized in that, the diameter of described fixed via is 2～5mm.
