Description
Technical field
It the utility model is related to the anticorrosion anti-aging technical field of bolt, and in particular to prevent the lock of bolt corrosion aging
Tight component.
Background technology
Metal bolts are widely used in the every field of industry, and it primarily serves connection or the fastening effect of hardware.
But in routine use, metallurgical and chemical industry equipment, pipeline etc. are all an exposure to outdoor mostly, therefore frequently encounter the outer of bolt
Reveal the screw thread of part by damage or the problem of get rusty, cause nut can not be disassembled from bolt.
Prior art often makes special nonmetallic protective case in the screw tip of bolt, by the exposed portion of bolt
Divide and nut is together wrapped up, avoid bolt from being contacted with water, prevent bolt from getting rusty, play the purpose of protection bolt；It is another
Method is to coordinate several nuts the exposed parts of bolt more so that the exposed parts of bolt are wrapped up by nut completely, play guarantor
Protect the effect of bolt.
But above there is problems with general two methods：
1) nonmetallic protective case special in first method, versatility is poor, and its length is by bolt protruded length
Influence, different bolts needs to make different protective cases, to guarantee to combine closely with bolt.Simultaneously for ease of installing,
The material that protective case uses is mostly plastics, rubber etc., so for a long time in the wild or bolt by external force it is larger in the case of,
Protective case is easy to weathering and crushed.
Although 2) second method can effectively avoid the destruction of external force, for bolt exposed parts it is longer when, just
Need many nuts.Operation inconvenience, it is not attractive in appearance enough, while cost is high.
Meanwhile both the above method all can not in protective case storing lubricating grease, to avoid bolt from getting rusty.
The content of the invention
In view of this, it is necessary to provide that a kind of cost is low, convenient use, while can effectively prevent bolt corrosion aging
Latch assembly.

The internal thread that end coordinates is connect, the protective case is fixed on the connection end, the external diameter of the connection end and the protection
The internal diameter of set is adapted, and the external diameter of the protective case is less than the inscribed circle of the nut end regular polygon, in the protective case
Outer wall both sides are relatively set with clamping face, and the clamping face is parallel to protective case, to facilitate dismounting protective case.
Preferably, the side number of the regular polygon of described nut one end is >=3.
Preferably, the internal thread length of the nut end is less than or equal to the length with the nut.
Preferably, the protective case uses metal material, and the length of protective case is designed to different length according to bolt length
Or general length, on the outer wall of the protective case every 3cm set a groove, so as to according to actual use situation to mistake
Long part is removed.
Preferably, the clamping face on the protective case outer wall can be oppositely arranged 1 pair, 2 pairs or 3 pairs.
Preferably, rubber washer is provided between the nut and protective case, so that nut and protective case are fitted close,
Rainwater is avoided to flow into nut and protective case so as to be got rusty between protective case and nut, and cause protective case to be difficult to from nut
Remove.
Preferably, protective layer is set in the cavity also between protective case and bolt, also covered in the openend of protective case
Protection cap, the cavity between protective case and bolt is blocked.
Preferably, protective layer is anti-rust and lubrication grease.
The utility model uses above-mentioned technical proposal, and its advantage is：The present apparatus includes bolt, nut and protection
Set, the nut and protective case are coordinated by screw thread to be fixed together, and the nut includes nut end and connection end, the nut
End is fixedly connected with the connection end, and the connection end is cored screw, and the nut end is enclosed on bolt, and connection end is also enclosed on
Leakage is on the bolt on the outside of nut end, and in assembling, nut end plays a part of fixing bolt, and cored screw plays installation and protected
The effect of sheath, and being threadedly coupled between protective case and cored screw so that protective case do not allow it is easy to fall off, in this way, protective case with
Connection end collective effect plays a part of protecting bolt to prevent corrosion and ageing, recessed every 3cm settings one on the protective case
Groove, to be removed according to actual use situation to excessive portion.
The nut and protective case coordinate simply, and convenient disassembly is versatile, can effectively protect bolt anti-rain to get rusty,
The environmental corrosions such as acid rain.Protective case uses metal material, will not aging, improve the service life of bolt, reduce and change, reduce
Cost.
