Abstract

The utility model relates to a protective cover. A sanding protective cover comprises an annular elastic rubber ring, wherein the elastic rubber ring is made of magnetic rubber, and the outer diameter of the elastic rubber ring is matched with the diameter of an inner hole of a protected part. Due to the fact that the elastic rubber ring is magnetic, the surface of the rubber ring can be attracted to and fixed on the wall of the inner hole of the part when the elastic rubber ring is inserted into the hole, and then damage on the inner hole in a sanding process of the part can be effectively avoided, and the protective effect is achieved. Furthermore, due to the utilization of magnetic attraction, installation and dismantling are simple and fast, and working efficiency is improved.

Description

A kind of sanding protective jacket
Technical field
The utility model relates to a kind of protector, is specifically related to a kind of protective jacket.
Background technology
As everyone knows, a lot of machine components need the sanding rust cleaning, but part easily destroys the roughness of its endoporus in the sanding process through the pore volume of machined processing before sanding, and for the bigger endoporus in aperture, and conventional means of defence can't effectively protect.
Summary of the invention
The utility model provides a kind of sanding protective jacket in order to overcome the deficiency of above technology.
The technical scheme that its technical problem that overcomes the utility model adopts is:
This sanding protective jacket, comprise annular flexible rubber ring, described flexible rubber ring adopts magnetic rubber to make, and the diameter of bore of its external diameter and the part of protecting is complementary.
In order to improve the applying tightness degree of flexible rubber ring and part endoporus, also comprise the inflation supporter with closed cavity that is arranged in the flexible rubber ring, described inflation supporter top is provided with inflation inlet.
For convenience flexible rubber ring is taken out, also comprise the draw ring of the annular that is arranged at magnetic cushion rubber top.
The beneficial effects of the utility model are: because flexible rubber ring has magnetic; therefore flexible rubber ring is inserted into that its cushion rubber appearance can be fixed on the hole wall in adhesive in the part endoporus; can effectively prevent part destruction to endoporus in the sanding process, play a protective role.And adopt magnetic attracting mode to make and improved operating efficiency by the installing/dismounting simple and fast.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view;
Among the figure, 1. hole wall 2. flexible rubber rings 3. are inflated supporters 4. inflation inlets 5. draw rings.
The specific embodiment
Be described further below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing.
This sanding protective jacket, comprise annular flexible rubber ring 2, described flexible rubber ring 2 adopts magnetic rubbers to make, and the diameter of bore of its external diameter and the part of protecting is complementary.Because flexible rubber ring 2 has magnetic, therefore flexible rubber ring 2 is inserted into that its cushion rubber appearance can be fixed on the hole wall 1 in adhesive in the part endoporus, can effectively prevent part destruction to endoporus in the sanding process, play a protective role.And adopt magnetic attracting mode to make and improved operating efficiency by the installing/dismounting simple and fast.
Also comprise the inflation supporter 3 with closed cavity that is arranged in the flexible rubber ring 2, described inflation supporter 3 tops are provided with inflation inlet 4.After being inserted into flexible rubber ring 2 in the part endoporus, thereby by 4 inflations can make supporter 3 expansions that flexible rubber ring 2 is fitted tightly on the circumferential surface of hole wall 1 to inflation inlet, improve protection effect.
The draw ring 5 that also comprises the annular that is arranged at magnetic cushion rubber 2 tops.After sanding finishes can by with the finger draw ring 5 flexible rubber ring 2 is taken out from the endoporus of part, convenient and swift.

Claims (3)
