Abstract
The utility model relates to a kind of novel powerful environmental protection button, comprise the lower fastener of ring, on lower fastener, combination is provided with the upper button of identical ring, the annulus of upper button is distributed with groove symmetrically centered by the center of circle, groove is set to square, or groove is set to trapezoidal, its length of side being positioned at the trapezoidal base of annulus excircle of trapezoidal groove is greater than the length of side of the trapezoidal top margin being positioned at annulus inner circumference, and the length of side on trapezoidal base is 4:3 with the length ratio of the length of side of trapezoidal top margin; The diameter of the excircle of the annulus of upper button and lower fastener and the diameter of inner circumference are than being 19:8; The distance of trapezoidal base and the excircle of annulus is 3:5 with trapezoidal top margin and the ratio of the distance of the inner circumference of annulus; Its pulling force increases, not yielding, good environmental protection, is convenient to reclaim, and meets the needs of actual conditions.
Description
Technical field
The utility model belongs to tarpaulin technical field, relates to a kind of tarpaulin button, particularly relates to a kind of novel powerful environmental protection button.
Background technique
At present, the loop configuration that the many employings of button conventional on tarpaulin are single, it is little to there is pulling force in it, easy distortion, environmental-protecting performance is poor, reclaims the problems such as loaded down with trivial details, for this reason, need a kind of novel powerful environmental protection button that can solve the problems referred to above in prior art, its pulling force is increased, not yielding, good environmental protection, be convenient to reclaim, meet the needs of actual conditions.
Model utility content
The purpose of this utility model is, provides a kind of novel powerful environmental protection button, its pulling force is increased, not yielding, good environmental protection, is convenient to reclaim, and meets the needs of actual conditions.
For achieving the above object, the utility model provides a kind of novel powerful environmental protection button, comprise the lower fastener of ring, on lower fastener, combination is provided with the upper button of identical ring, the annulus of upper button is distributed with groove symmetrically centered by the center of circle, groove is set to square, or groove is set to trapezoidal, its length of side being positioned at the trapezoidal base of annulus excircle of trapezoidal groove is greater than the length of side of the trapezoidal top margin being positioned at annulus inner circumference, and the length of side on trapezoidal base is 4:3 with the length ratio of the length of side of trapezoidal top margin; The diameter of the excircle of the annulus of upper button and lower fastener and the diameter of inner circumference are than being 19:8; The distance of trapezoidal base and the excircle of annulus is 3:5 with trapezoidal top margin and the ratio of the distance of the inner circumference of annulus.
In above scheme preferably, the degree of depth of groove is 0.3mm.
Can also preferably, combined by arranging tarpaulin between lower fastener and upper button.
Compared with prior art, the utility model has the following advantages:
Novel powerful environmental protection button of the present utility model, its pulling force increases, not yielding, good environmental protection, is convenient to reclaim, and meets the needs of actual conditions.
