Abstract
The utility model relates to a kind of flexible open type protective housing, it is the cylindrical shell of approximate C shape for cross section, cylinder lateral wall is made up of the ring bodies of a plurality of approximate C shapes, the ring bodies cross section becomes the V font, be provided with the annular brace sheet of the approximate C shape of supporting the ring bodies flange in the ring bodies, ring bodies is fixedly connected with retaining ring in the flange place of the lower wall of opening, ring bodies is fixedly connected with one in the flange place of the upper side wall of opening and has the last retaining ring that keeps off cloth, be equipped with a cotter pin on last retaining ring and the following retaining ring, retaining cloth blocks the opening of cylindrical shell.Therefore, the flexible open type protective housing of the utility model need not dismounting equipment when installation or removal, can pass through of the piston rod side installation or removal of the opening of cylindrical shell from cylinder or oil cylinder, can effectively shorten the installing/dismounting time like this, make equipment keep relative continuity work, enhance productivity.
Description
Technical field
The utility model relates to a kind of extension-type shelter that is used for oil cylinder or cylinder piston rod external part, refers to a kind of flexible open type protective housing especially.
Background technique
At present, the extension-type shelter that is used for equipment protections such as metallurgy industry oil cylinder, cylinder, it is a cylindrical shell, cylinder lateral wall is made up of a plurality of ring bodies, the ring bodies cross section becomes the V font, is provided with the ring-type support plate that supports the ring bodies flange in the ring bodies, wherein the internal diameter of ring-type support plate internal diameter less than ring bodies arranged, the ring-type support plate internal diameter that has is greater than the ring bodies internal diameter, cylindrical shell side imperforation.During installation, need dismounting connection device earlier, again extension-type shelter is enclosed within the piston rod external part of oil cylinder, cylinder etc., afterwards the piston rod external part is connected with connection device, and extension-type shelter one end is fixed on the cylinder body, the other end is fixed on the connection device, so realizes dustproof, grease proofing, fire prevention, waterproof, acidproof, alkaline-resisting effect, make equipment avoid corrosion, proper functioning for a long time.But this extension-type shelter needs earlier connection device to be dismantled when installation and removal, could mount and dismount extension-type shelter afterwards, this shows that this extension-type shelter installing/dismounting is very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of flexible open type protective housing of easy installation and removal.
For achieving the above object, the utility model is taked following design proposal: a kind of flexible open type protective housing, it is characterized in that: it is the cylindrical shell of approximate C shape for cross section, described cylinder lateral wall is made up of the ring bodies of a plurality of approximate C shapes, described ring bodies cross section becomes the V font, be provided with the annular brace sheet of the approximate C shape of supporting the ring bodies flange in the described ring bodies, described ring bodies is fixedly connected with retaining ring in the flange place of the lower wall of opening, described ring bodies is fixedly connected with one in the flange place of the upper side wall of opening and has the last retaining ring that keeps off cloth, described going up on retaining ring and the following retaining ring is equipped with a cotter pin, and described retaining cloth blocks the opening of described cylindrical shell.
Described ring bodies is that profile is circular ring bodies.
Described ring bodies is that profile is foursquare ring bodies.
Described ring bodies is that profile is rectangular ring bodies.
The utility model has the advantages that:
1, the flexible open type protective housing of the utility model, it is the cylindrical shell of approximate C shape for cross section, cylinder lateral wall is made up of the ring bodies of a plurality of approximate C shapes, the ring bodies cross section becomes the V font, be provided with the annular brace sheet of the approximate C shape of supporting the ring bodies flange in the ring bodies, ring bodies is fixedly connected with retaining ring in the flange place of the lower wall of opening, ring bodies is fixedly connected with one in the flange place of the upper side wall of opening and has the last retaining ring that keeps off cloth, be equipped with a cotter pin on last retaining ring and the following retaining ring, retaining cloth blocks the opening of cylindrical shell.Therefore, the flexible open type protective housing of the utility model when mounted, need not dismounting equipment, opening that can be by cylindrical shell from the piston rod side encapsulation of cylinder or oil cylinder to piston rod, to keep off cloth again and cover in opening, and cotter pin worn to be enclosed within to go up retaining ring on retaining ring and the following retaining ring and link together with following retaining ring and get final product, can effectively shorten the installation time like this, make equipment keep relative continuity work, enhance productivity.Correspondingly, the flexible open type protective housing of the utility model is when dismounting, also need not dismounting equipment, can be earlier cotter pin be pulled down from last retaining ring and following retaining ring, cylindrical shell is removed from piston rod from the piston rod side of cylinder or oil cylinder by the opening of cylindrical shell and got final product.This shows that the flexible open type protective housing installing/dismounting of the utility model is all very convenient.
2, the flexible open type protective housing of the utility model, wherein ring bodies can be that profile is circular ring bodies or foursquare ring bodies or rectangular ring bodies according to the different designs of piston rod beginning.
