Abstract
The utility model discloses a protection shield for bolt and nut, which consists of a hollow bolt protection chamber and a nut protection chamber; the inner cavity shape of the nut protection chamber can adapt with the shape of the nut; the bolt protection chamber is positioned above the nut protection chamber; the upper end of the bolt protection chamber is closed, and the lower end of the bolt protection chamber is communicated with the inner cavity of the nut protection chamber. With the structure, the protection shield can be covered on the fixed bolt and nut to isolate totally from outside when used, the corrosion by the outside environment is avoided, the rusty problem on the bolt and nut can be radically stopped; the disassembly is easy, and the operation efficiency can be improved. Simultaneously, the bolt and the nut can be reused to reduce the operation cost. The utility model has the advantages of reasonable structure, easy fabrication, easy disassembly and installation and wide application scope.
Description
One, technical field
The utility model belongs to technical field of fastening, is specifically related to a kind of bolt, nut protective housing.
Two, background technique
At present, bolt, the nut as fastening piece is widely used in all trades and professions.But in use owing to bolt, the unshielded device in nut outside, can only be directly exposed in the air, be subjected to the corrosion of external environments such as rainwater and dust all the year round, bolt silk mouth, nut very easily corrosion cause rust dead, make that it is difficult to unload to get, can only adopt destructive means such as electric saw, fire weldering or chemical reagent to dismantle, not only waste time and energy, reduce working efficiency, and fastening piece also can be because of destroyed, can't utilize once more and cause waste, increase user cost.The operating mode such as railway, the bridge etc. that particularly need a large amount of bolts, nut influence more serious.
Three, summary of the invention
The purpose of this utility model is to carry a kind of simple in structurely, reasonable in design, can effectively protect bolt, nut, avoids bolt, the nut protective housing of external environment corrosion.
For achieving the above object, the technical solution adopted in the utility model is: bolt guard chamber and nut guard chamber by hollow are formed; The cavity shape and the nut shape of nut guard chamber adapt; The bolt guard chamber is positioned at the top of nut guard chamber, its upper end closed, and the lower end communicates with nut guard chamber inner chamber.
Adopt the said structure protective housing, during use, it is enclosed within fastening good bolt, above the nut, they and the external world is isolated fully, avoided by the corrosion of external environment.Fundamentally stopped the become rusty generation of dead phenomenon of bolt, nut.Convenient disassembly has improved working efficiency.Simultaneously, bolt, nut can also be utilized once more, have reduced user cost.The utility model is rational in infrastructure, making is easy, removes and installs conveniently, has wide range of applications.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode figure.
Five, embodiment
By accompanying drawing as seen, the utility model is made up of the bolt guard chamber 1 and the nut guard chamber 2 of hollow structure; The shape of the cavity shape of nut guard chamber 2 and size and nut 4 and measure-alike.Bolt guard chamber 1 is positioned at the top of nut guard chamber 2, its upper end closed, and the lower end communicates with nut guard chamber 2 inner chambers.Nut guard chamber 2 and bolt guard chamber 1 can be made all size according to nut 4, bolt 3 external form nominal size, and the height of bolt guard chamber 1 also can be made into different size.Form the convenient supporting use of series product; But nut guard chamber 2 internal diameter sizes and nut 4 external form nominal size interference fit, the utility model just can be stuck on the nut 4 like this, has avoided in use coming off, and has made things convenient on ambulant equipment and has used.In order to increase anti-corrosion function of the present utility model, can smear impregnating fluid in the outside of bolt 3, nut 4 before using, again the utility model is put.The utility model can be made by plastic materials, like this, not only low cost of manufacture, and difficult wearing out, long service life, protection effect is good.
