Detailed Description

The embodiment of the utility model discloses pulling-on piece to solve present pulling-on piece anterior segment horizontal pole portion problem of damaging easily effectively.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, fig. 1 is a schematic diagram of an explosion structure of a pull tab according to an embodiment of the present invention;

fig. 2 is an exploded schematic view of a slider according to an embodiment of the present invention; fig. 3 is a schematic cross-sectional view of a slider according to an embodiment of the present invention.

In a specific embodiment, the present embodiment provides a pull-tab, which is mainly applied to a slider having a horse hook 8, so that the pull-tab has better wear resistance. Specifically, the tab includes a body 1 and a barrier 3.

Wherein body 1 is the main functional unit of pulling-on piece, mainly divide into two parts, and the anterior segment has annular structure portion 2 promptly, and the back end has the portion 4 of tongs that is used for human hand operation, generally makes things convenient for human finger to hold between the fingers at least, and can apply the pulling force. The ring structure part 2 is mainly sleeved on the cap 9 of the pull head, and when the hook 8 is provided, the rod part in the ring structure part 2, which is arranged in the hole between the cap 9 and the pull body 7 in a penetrating way, is correspondingly clamped in the groove of the hook 8, so that when the pull piece is pulled, corresponding acting force is applied to the hook 8.

Wherein separation portion 3, for resistant separation portion 3 of rubbing, at least the resistant rubbing performance of separation portion 3 is higher than the resistant rubbing performance of body, adopts resistant separation portion 3 of rubbing its main aim at, avoids wearing and tearing in order to avoid appearing the colour difference, specifically like plastics separation portion, plastics are soft spare, difficult wearing and tearing, and even there is slight wearing and tearing, also hardly by people's eye discernment. The barrier 3 is again like a wear-resistant and corrosion-resistant metal part, so that no exterior paint, which is not wear-resistant, needs to be applied. Wherein the barrier 3 should be able to wrap around the ring-shaped structure 2 in the circumferential direction of the ring-shaped structure 2 instead of the ring-shaped structure 2, directly in contact with the cap 9 and the clevis 8.

In the pull tab, when the pull tab is applied to a slider with or without a horse hook 8, the pull tab is pulled, because the blocking part 3 is enclosed on the annular structure part 2 and is directly contacted with the horse hook 8 and/or the cap 9, and the annular structure part 2 of the pull tab body provides a supporting force for the blocking part 3, so that the pull tab can provide a acting force for the horse hook 8 and the cap 9. In this pulling-on piece, it has separation portion 3 to enclose on the annular structure portion 2 of pulling-on piece front end to directly contact with cap 9 and horse hook 8 through separation portion 3, avoided body 1 directly to contact with cap 9 and horse hook 8 and the problem of scraping the flower easily that wears out, and holding power and effort still come from annular structure portion 2, and then guaranteed the function of pulling-on piece. To sum up, this pulling-on piece can solve present pulling-on piece anterior segment rail portion problem of damaging easily effectively.

Further, it is preferable that the blocking portion 3 is wrapped around the front section of the body 1 to expose the rear section to form the handle portion 4, but the blocking portion 3 may be wrapped around the body 1. Here, the half wrapping is preferred, so that the grip 4 of the rear section of the pull tab is exposed, and the rear section is prevented from being too thick and inconvenient to operate.

Further, for better connection between the blocking portion 3 and the body 1, it is preferable that at least one through reinforcing hole slot 5 is formed on the rear portion of the front portion, and the blocking portion 3 includes a column portion penetrating the reinforcing hole slot 5, and both ends of the column portion are fixedly connected with portions of the blocking portion 3 at both ends of the reinforcing hole slot 5, so as to be clamped in the reinforcing hole slot 5 through the column portion, and further prevent the blocking portion 3 from being separated from the body 1. Specifically, the rear portion of the front section portion may have two reinforcing hole grooves 5 distributed in the front-rear direction, and the hole depth direction of the reinforcing hole groove 5 is the same as the hole depth direction of the ring hole in the ring structure portion 2.

Further, in order to avoid the separation of the barrier portion 3 from the tab body 1 in the front-rear direction, it is preferable here that the front section includes a waisted portion 6 located at the rear end of the annular structure portion 2 and having a width smaller than that of the annular structure portion 2, and the rear portion of the barrier portion 3 is correspondingly shrunk in the front width direction, and for better engagement, it is preferable here that the waisted portion 6 is excessive with the annular structure portion 2 by a tapered portion to form a smooth waisted portion.

Further, for the sake of aesthetic appearance, it is preferable that the rear end side surface of the blocking portion 3 and the front end side surface of the hand grip 4 are closely connected and smoothly transited so as to form a tightly connected whole as viewed from the overall contour.

The connection between the blocking part 3 and the body 1 is mainly divided into two types, one is that the blocking part 3 is injection molded on the body 1; the other is that the blocking part 3 is installed on the body 1 after installation, specifically, if the blocking part 3 comprises an upper piece and a lower piece which are separated along the hole depth direction in the annular structure part 2, the upper piece and the lower piece are connected in a clamping way, and specifically, the column part can be a clamping column for connecting the upper piece and the lower piece.

Based on the pulling-on piece that provides in the above-mentioned embodiment, the utility model also provides a pull head, this pull head include arbitrary pulling-on piece in the above-mentioned embodiment, still including pulling body 7, horse hook 8 and cap 9, the annular structure portion 2 of pulling-on piece and around the package are in the separation portion 3 of annular structure portion 2, the cover is established on the cap 9 and the card is in horse hook 8 corresponds the recess. Since the pull tab in the above embodiment is adopted in the slider, please refer to the above embodiment for the beneficial effect of the slider.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
