Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, clear, below tie
Close drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
The slide fastener of a kind of double engagements as a shown in Figure 6, left and right chain tooth A, B of this slide fastener engage each other and are fixed on strap
On 10.The chain tooth of slide fastener of the present invention includes the left and right chain intermeshing engagement post of tooth A, B 20, and is engaged in the root of the tooth of strap 10
30。
As illustrated in figs. 2 through 8, engagement post 20 of the present invention includes the first engagement post 21 and the second engagement post 22.Described first nibbles
Syncephalon 21 and the second engagement post 22 are sequentially integrally formed in engagement post 20 to root of the tooth 30 from the end face 23 of engagement post 20.
As shown in Fig. 2-5,7-9, chain tooth of the present invention formed between the first engagement post 21 and the second engagement post 22 first
Recess is the first engaging piece 24, and the second recess formed between described the second engagement post 22 and root of the tooth 30 is the second engaging piece
25.First width H1 of the present invention the first engaging piece 24 is less than the second width H2 of the second engaging piece 25；And described first engagement
The 3rd width L1 of 21 is less than the 4th width L2 of the second engagement post, so that (first engagement in microcephaly of described engagement post 20
21) upper, major part (the second engagement post 22) under smooth shape.
As a shown in Figure 6, under left and right chain tooth A, B engagement, first engagement post 21 of left chain tooth A is engaged on accordingly
Second engaging piece 25 of right chain tooth B of engagement, and the second engagement post 22 is engaged on first engaging piece of right chain tooth of corresponding engagement
24, to form the engagement shape of grinding one's teeth of firm double engaging pieces, improve the joggled strength of engagement rear zipper, and horizontal drawing strength, with
Time play good explosion-proof effect.
Such as Fig. 4, shown in 9, on the first of the present invention the first engaging piece 21, on field of conjugate action 21A and second, field of conjugate action 21B is
Inclined-plane, so that the opening angle a of the first described engaging piece 241Scope is 55 to 60 degree.
On the second of second engaging piece 22 of the present invention, field of conjugate action 22A is also configured as inclined-plane, the angle of inclination on this inclined-plane
a2For 25-45 degree.On the two of second engaging piece 2, on field of conjugate action 22A and the first of the first engaging piece 21, field of conjugate action 21A is parallel.?
In embodiment one shown in Fig. 4, the end face 23 of described first engagement post 20 is flat face, second time engagement of the second engaging piece 22
Face 22B is also configured as flat face to end face 23 that should be straight.Optimal, in the embodiment two shown in Fig. 9, described second nibbles
Second time field of conjugate action 22B in conjunction portion 22 is designed as inclined-plane, so that the opening angle a of the second engaging piece 253Scope is 30 to 50 degree.
And the end face 23 of the present invention the first engagement post 20 is provided with the chamfering parallel for field of conjugate action 22B with the second of this second engaging piece 22 time
232.The angle of inclination design of engagement post 20 of the present invention, makes tooth head relatively more sharp-pointed, reduces the resistance between chain tooth when engaging, and pass through
Parallel design promotes smoothness during slide fastener engagement further, and while sense is drawn in lifting, promotes left and right chain tooth A, B
Engagement fastness.
As shown in Fig. 2,3,7,8, in the middle part of the end face 23 of the present invention the first engagement post 20, it is provided with a short slot 231；So that it is left and right
The engagement of chain tooth A, B smooth, engagement is easier to, and while promoting the light slippery of engagement further, also makes slide fastener have
More excellent bending motility, flexibility is promoted further.
Description above describe the preferred embodiments of the present invention, it is to be understood that the present invention is not limited to above-mentioned enforcement
Example, and should not regard the eliminating to other embodiments as.By the enlightenment of the present invention, those skilled in the art combine known or existing
The change that technology, knowledge are carried out also should be regarded as within the scope of the present invention.
