Abstract
The utility model provides a screw cap protecting jacket which protects a machine, a screw cap on the device and the outer part of the screw cap with a protecting jacket from contacting with aggressive gas and liquid, from the dust and moisture to maintain the screw and the screw cap non-corrodible and stainless. The utility model is characterized in that the fastened screw and screw cap is provided with a sealing jacket possessing flexible wrinkles matched with the exposed shape of screw and screw cap. The sealing jacket is in a hollow cylinder shape. Flexible wrinkles are arranged above the cylinder. The lower end of the sealing jacket is provided with a hooked port or a button-shaped port.
Description
Affiliated technical field
The utility model relates to screw rod nut or the bolt and nut on a kind of machinery, the equipment, prevents the protecting jacket that screw rod or nut get rusty.
Background technique
In the middle of machinery, as fastening piece, be the part of usually using in the machinery with the screw rod nut, these parts are because of being subjected to nature wind, rain and be subjected to corrosive gas, the corrosion of liquid or be subjected to dust, the corrosion of aqueous vapor, screw rod nut generation corrosion, oxidation, thereby the fastening performance of influence machinery, reduce original constant intensity of screw rod nut, give maintenance, dismounting brings a lot of difficulties, thereby delayed the maintenance progress, serious even generation that cause accident.
Summary of the invention
The purpose of this utility model is a kind of screw rod nut protecting jacket that provides in order to overcome above-mentioned deficiency; this cover protects the bolt on the machinery, nut exposed parts with protecting jacket; make the bolt and nut corrosion on the machinery; get rusty,, just can play protection screw rod and nut non-corrosive in some several years because protecting jacket has been installed; to reach the prolongation screw rod; the working life of nut, can also prevent screw rod, nut because of corrosion, damage and the accident that causes.
The technological scheme that the utility model technical solution problem is adopted is: a kind of screw rod nut protecting jacket; it is characterized in that: protecting cover (6) is made as band tip circle tubular; the upper diameter of cylindrical shape protecting cover is less than lower diameter; the top inside and outside wall of protecting cover cylinder is made as the barrel (7) of being with gauffer, and the lower end of protecting cover (6) is made as tube with hook (cover) mouthful (5) or buckles shape tube (cover) mouthful (5`).
Screw rod nut protecting jacket described in the utility model,, the vertical inside and outside wall of protecting jacket top cylinder is provided with flexible (elasticity) gauffer of shape of threads.
The beneficial effects of the utility model are: when the protecting cover with longitudinal extension is installed on the screw rod nut, can avoid the screw rod nut with the protecting cover bursting, guarantee that the protecting cover sealing is reliable, can prevent machine, the corrosion that exposes screw rod, nut on the equipment, prolong the working life of screw rod nut, the dismounting nut also seems convenient during maintenance, also can prevent the screw head that exposes and the accidental mechanical damage of nut.
