Problems solved by technology

[0003] The invention provides a tightenable expansion screw through which the toilet cover is fixed on the toilet, which can not only solve the problem that the friction between the stainless steel screw and the porcelain toilet can easily cause cracks in the toilet, but also solve the problem of using ordinary expansion screws When fixing, the ordinary expansion screw thread is easy to slip, resulting in the problem of not tightening the fixation
[0005] The beneficial effects of the present invention are: the present invention provides a tightenable expansion screw through which the toilet lid is fixed on the toilet, which can solve the problem that the friction between the stainless steel screw and the porcelain toilet can easily lead to cracks in the toilet, It can also solve the problem that when ordinary expansion screws are used for fixing, the opening of the ordinary expansion screw is easy to slip, resulting in the problem that the fixation is not tight

Abstract

The invention discloses a tightenable expansion screw, which includes screws, support plates, connecting plates, elastic fixing plates, buffer plates, nuts, screws, and stabilizing plates; the invention provides a tightenable expansion screw, through which the toilet lid This tightenable expansion screw is fixed on the toilet, which can not only solve the problem of cracks in the toilet due to the friction between the stainless steel screw and the porcelain material toilet, but also solve the problem that when the ordinary expansion screw is used for fixing, the opening of the ordinary expansion screw is easy to slip, causing the fixation Not a tight question.

Description

technical field [0001] The invention relates to an expansion screw, in particular to a tightenable expansion screw. Background technique [0002] In the family, the role of the toilet is extremely important. In the bathroom, the role of the toilet is particularly important. People cannot do without the toilet; after using the toilet, in order to keep the air fresh, people habitually cover the toilet cover; the toilet is made of porcelain Made of high-quality materials, when the toilet cover is fixed by ordinary stainless steel screws, when the toilet cover is under the cover and lifted for a long time, the friction between the stainless steel screw and the porcelain material toilet will easily cause cracks in the toilet; when the toilet cover is fixed by ordinary expansion screws, Because the expansion screw is made of plastic material, the opening of the ordinary expansion screw is easy to slip, so that the fixation is not tight. Contents of the invention [0003] The in...
