Abstract
A kind of barb-shaped chain tooth, including integrally formed tooth head and tooth body, described tooth head includes head and neck, wherein, head and the junction of neck are inside barb type structure, and the width of described neck is more than the width on head, described tooth body and the side outer face that zipper cloth belt coordinates is circular arc；Technical scheme described in the utility model is relative to prior art, a kind of new chain tooth is provided, its tooth form is barb type, its horizontal drawing strength can be increased, the horizontal drawing strength of slide fastener is strong, and slide fastener will not burst and open, and slide fastener must compare loosening, therefore slide fastener, which is drawn, feels more smooth, and suitability is strong, it is not necessary to special pull head of arranging in pairs or groups.
Description
Technical field
The utility model is related to a kind of zipper technology field, specifically relevant with a kind of barb-shaped chain tooth of slide fastener.
Background technology
Slide fastener is the product that can usually use in our daily lifes, with folding with convenience, it is quick the characteristics of, application
Extensively, extensive application therefore on the product such as clothes, case and bag.Increase in demand with people to slide fastener, it is desirable to be consequently increased,
Attractive in appearance, practicality is not required nothing more than, is also required that its intensity, but existing slide fastener, is more tended to chain tooth and the bond strength of strap,
But the combination between chain tooth produces the phenomenon of quick-fried chain if insufficient strength.
Utility model content
The purpose of this utility model is solution problem of the prior art, and there is provided a kind of simple in construction, easy to operate
A kind of barb-shaped chain tooth of slide fastener, after chain tooth is engaged, chain tooth will not burst open, and can draw tighter and tighter on the contrary, improve the chain of slide fastener
Tooth bond strength.
To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：
A kind of barb-shaped chain tooth, including integrally formed tooth head and tooth body, described tooth head include head and neck, its
In, the junction of head and neck is inside barb type structure, and the width of described neck is more than the width on head.
Further, described tooth body and the side outer face that zipper cloth belt coordinates are circular arc.
Further, described tooth body is more than the width of opposite side, and wide side with the side width that zipper cloth belt coordinates
End face formation lead angle.
Technical scheme described in the utility model is relative to prior art there is provided a kind of new chain tooth, and its tooth form is barb
Type, can increase its horizontal drawing strength, and the horizontal drawing strength of slide fastener is strong, and slide fastener will not burst and open.And slide fastener must compare loosening, because
This slide fastener, which is drawn, feels more smooth, and suitability is strong, it is not necessary to special pull head of arranging in pairs or groups.

Embodiment
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are clearer, clear, with
Under in conjunction with the accompanying drawings and embodiments, the utility model is further elaborated.It should be appreciated that specific reality described herein
Example is applied only to explain the utility model, is not used to limit the utility model.
It is the utility model embodiment as shown in Fig. 1-Figure 10.
It is the utility model embodiment one refering to such as Fig. 1-4, Fig. 8-10.
A kind of barb-shaped chain tooth, including integrally formed tooth first 1 and tooth body 2, described tooth first 1 include head 11 and neck
12, wherein, the junction of head 11 and neck 12 is inside barb type structure 3, and the width of described neck 12 is more than head
The width in portion 11；Described tooth body 2 is circular arc 21 with the side outer face that zipper cloth belt coordinates.
Tooth form of the present utility model is barb type, can increase its horizontal drawing strength.After chain tooth is engaged, chain tooth will not burst
Open, can draw tighter and tighter on the contrary.But the slide fastener is when pulling open, the tooth head of slide fastener coupling element must leave enough spaces, be exactly adjacent
The barb of two chain tooths on opposite must separate some distances, and otherwise chain tooth can not be pulled open or pulled open because hooking and have some setbacks.
And the slide fastener coupling element of this programme is big due to space, therefore chain tooth conjunction width can become big, and possible common pull head mouthful is wide can be wide less than the conjunction.
The chain tooth of the design is designed with arc at tooth pin, with guide function.When pull head is pulled, even if slide fastener coupling element closes wide maximum
(being more than pull head mouthful wide), arcuate guide can still make chain tooth smoothly enter pull head, realize that slide fastener is engaged.
The utility model yet another embodiment, the width of side 22 that described tooth body 2 coordinates with zipper cloth belt is more than
The width of opposite side, and a wide side end face forms lead angle 23.
The utility model in chain tooth side due to increasing width, and the side has chamfering, and chamfering has guide effect.Drawing
When head is pulled, increase width side can enter pull head in advance, even if slide fastener coupling element closes wide maximum (being more than pull head mouthful wide), chamfering
Guiding can still make chain tooth smoothly enter pull head, realize that slide fastener is engaged.
The utility model provides a kind of new chain tooth, and its tooth form is barb type, can increase its horizontal drawing strength, the horizontal drawing of slide fastener
Strength is strong, and slide fastener will not burst and open.And slide fastener must compare loosening, therefore slide fastener draws sense more smooth, and suitability is strong, is not required to
Arrange in pairs or groups special pull head.
Preferred embodiment of the present utility model has shown and described in described above, as previously described, it should be understood that this practicality is new
Type is not limited to form disclosed herein, is not to be taken as the exclusion to other embodiment, and available for various other groups
Close, change and environment, and above-mentioned teaching or the technology of association area can be passed through in utility model contemplated scope described herein
Or knowledge is modified.And the change and change that those skilled in the art are carried out do not depart from spirit and scope of the present utility model, then
All should be in the protection domain of the utility model appended claims.
