Abstract
The utility model relates to the slide fastener that a kind of structure is simple, the chain tooth of occlusion can be prevented separated, comprise chain tooth, pull head, two chain bands, the relative side of two panels chain band is embedded with a row chain tooth respectively, two row chain tooth mutual dislocation engagements, pull head is stuck on the chain tooth of the relative side plate of chain band, described chain tooth comprises head, be located at clamping bar on head between head and chain band, and described head is provided with Access Division near the side of another chain band, and when two row chain teeth engagements, Access Division is connected on clamping bar.
Description
Technical field
The utility model relates to a kind of slide fastener.
Background technology
Existing slide fastener, generally includes chain tooth, pull head, two chain bands, and the relative side of two panels chain band is embedded with a row chain tooth respectively, and two row chain tooth mutual dislocation engagements, pull head is stuck on the chain tooth of the relative side plate of chain band.Slide fastener is applied to clothes, handbag etc. usually, if utilize sharp-pointed article to be separated from occlusion position by the chain tooth of slide fastener easily.Such situation, when being applied to handbag, is often easier to be stolen.
Summary of the invention
The technical problems to be solved in the utility model is to provide the slide fastener that a kind of structure is simple, the chain tooth of occlusion can be prevented separated.
For achieving the above object, the technical solution of the utility model is: a kind of slide fastener, comprise chain tooth, pull head, two chain bands, the relative side of two panels chain band is embedded with a row chain tooth respectively, two row chain tooth mutual dislocation engagements, pull head is stuck on the chain tooth of the relative side plate of chain band, and described chain tooth comprises head, be located at clamping bar on head between head and chain band, described head is provided with Access Division near the side of another chain band, and when two row chain tooth engagements, Access Division is connected on clamping bar.
Preferably, described clamping bar has two, is located at the left and right side of chain tooth respectively.
Preferably, described clamping bar is oval rod.
Preferably, described head is respectively equipped with circular arc chamfering near the two ends, left and right of the side of clamping bar.
Technique scheme has following beneficial effect: by being provided with Access Division on the head of chain tooth, clamping bar is provided with between head and chain band, coordinating thus the chain tooth of slide fastener can be prevented separated by Access Division and clamping bar, thus make the protectiveness of slide fastener stronger, have more practicality; Further, the quantity that clamping bar is arranged is two, lays respectively at the left and right side of chain tooth, thus makes each chain tooth can with the clamping bar phase clamping of two chain teeth of relative side, thus make the continuity of whole slide fastener, clamping more by force, tightr.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional view at A-A place in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in further detail.
Shown in Fig. 1, Fig. 2, the present embodiment provides a kind of slide fastener, comprise chain tooth 1, pull head, two chain bands 2, the relative side of two panels chain band 2 is embedded with a row chain tooth 1 respectively, two row chain tooth 1 mutual dislocation engagements, pull head is stuck on the chain tooth 1 of the relative side plate of chain band 2, described chain tooth 1 comprises head 11, be located at clamping bar 12 on head 11 between head 11 and chain band 2, described head 11 is provided with Access Division 111 near the side of another chain band 2, and when two row chain teeth 1 engage, Access Division 111 is connected on clamping bar 12.Described clamping bar 12 has two, is located at the left and right side of chain tooth 1 respectively.Described clamping bar 12 is oval rod.Described head 11 is respectively equipped with circular arc chamfering 112 near the two ends, left and right of the side of clamping bar 12.
Above-mentioned chain tooth, is set to circular arc by Access Division on head, and the arc length of this circular arc is less than the half of circumference, and the radius of this circular arc slightly larger than the short radius of clamping bar, thus can coordinate better; The head of above-mentioned chain tooth, by arranging circular arc chamfering, can realize the snap-fit engagement of left and right two row chain teeth better.
By being provided with Access Division on the head of chain tooth, between head and chain band, be provided with clamping bar, coordinating thus the chain tooth of slide fastener can be prevented separated by Access Division and clamping bar, thus make the protectiveness of slide fastener stronger, have more practicality; Further, the quantity that clamping bar is arranged is two, lays respectively at the left and right side of chain tooth, thus makes each chain tooth can with the clamping bar phase clamping of two chain teeth of relative side, thus make the continuity of whole slide fastener, clamping more by force, tightr.
Below be only the utility model preferred embodiment, those skilled in the art makes by claim the protection domain that equivalent change all falls into this case.
