Detailed description of the invention
With the following Examples the utility model is further described.
A kind of changeable type anti-error lock protective cover, is characterized in being provided with removable protective plate in the bottom of lockset, can be divided into two kinds of local formula protective cover and monoblock type protective covers.
The material of this protective cover adopt high-quality can resistance to high/low temperature, waterproof sun-proof, elastomeric silicon rubber, owing to using out of doors, long term exposure in the sun, for the object that reaches antiultraviolet and prolongation ageing time has been added multiple anti-aging composition, and has been carried out a large amount of verification experimental verifications. Through exposing measuring outside ultraviolet ray ageing or room, this protective cover has following character:
(1) measuring material has just started until be identified on surface that the time of be full of cracks is greater than 10 years;
(2) measure material and continue ultraviolet ray ageing or Sunlight exposure, but the time only reaching till initial value 50% is greater than 13 years;
