Description

Automatic zipper locking head of zipper

Technical Field

The utility model relates to a zip fastener hardware, especially an automatic lock pull head of zip fastener.

Background

Zippers are connecting members for uniting or separating articles by means of a continuous arrangement of zipper teeth, and are widely used for articles such as clothes, bags, tents, and the like. In order to avoid the pull head of zip fastener to lead to the zip fastener to be unzipped under the action of gravity naturally landing, many zip fasteners all dispose automatic lock pull head, and this type of automatic lock pull head compresses tightly through reed spare crotch for the crotch imbeds chain tooth, effectively avoids the pull head to naturally landing under the action of gravity, when needing the pulling head, promotes the reverse reed that promotes of crotch through the pulling-on piece, makes the crotch deviate from the chain tooth.

In order to ensure that the pull piece has a movement space for pushing the horse hook to reversely push the reed, two sides of the cap of the automatic lock slider are generally required to be provided with notches which are generally square notches, however, when the automatic lock slider is subjected to a paint spraying process and other surface coating processes after being assembled, paint easily flows into a position between the reed and the cap of the slider from the square notches due to the existence of the square notches, so that the reed is stuck by the paint or is stuck to a column, and the production reject ratio is relatively high.

In view of the above, the applicant has made an intensive study on the structure of the automatic zipper puller, and has made this disclosure.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a zipper automatic locking pull head comprises a pull head main body, a pull piece, a horse hook, a spring leaf and a cap, wherein the cap is fixedly connected to the pull head main body, the horse hook and the spring leaf are both positioned between the pull head main body and the cap, one side of the reed is propped against the cap cover, the other side of the reed is propped against the horse hook, one end of the pulling piece is arranged between the horse hook and the puller body, the cap is provided with an inner cavity with an opening arranged towards the direction of the puller body, the side walls of the inner cavity at the two sides of the cap in the width direction are respectively provided with a notch for the pull piece to pass through, the groove wall of one side of each notch far away from the puller body is respectively provided with a blocking piece, the reed is blocked by the blocking piece, and grooves are respectively formed between the side walls of the two sides of the length direction of the cap cover and the corresponding blocking blocks in each notch.

As an improvement of the present invention, the blocking piece is in the side surfaces of both sides of the length direction of the cap are inclined surfaces or arc surfaces.

As an improvement of the utility model, the reed is the V font under initial condition and arranges, just the both ends of reed are supported respectively and are in on the cap, the middle part position of reed is supported and is in on the horse hook.

As an improvement of the utility model, set up on the pulling-on piece with lack groove complex perforation, the perforation with the pulling-on piece is close to be formed with between the terminal surface of the one end of pulling head main part and wear the pole, hide the dog with interval between the pulling head main part equals or slightly is greater than wear the width or the thickness of pole.

After the technical scheme is adopted, the utility model discloses following beneficial effect has:

through setting up and hiding the dog, when the process of spraying paint, owing to hide stopping of dog, paint is difficult to flow into the position department between reed and the cap, and the reed is difficult to be glued or the card post by paint, and the production defective rate is lower relatively.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the automatic zipper locking slider of the present embodiment includes a slider body 10, a pull tab 20, a hook 30, a spring plate 40 and a cap 50, wherein the cap 50 is fixedly connected to the slider body 10, the hook 30 and the spring plate 40 are both located between the slider body 10 and the cap 50, one side of the spring plate 40 abuts against the cap 50, and the other side abuts against the hook 30, specifically, the spring plate 40 is arranged in a V shape in an initial state, two ends of the spring plate 40 respectively abut against the cap 50, and a middle position of the spring plate 40 abuts against the hook 50; one end of the pull tab 20 is installed between the horse hook 30 and the slider body 10, it should be noted that the structures of the slider body 10, the pull tab 20, the horse hook 30 and the spring plate 40 are the same as those of the conventional automatic zipper locking slider, and are not the focus of the embodiment, and detailed description is omitted here.

The cap 50 has an inner cavity with an opening arranged towards the direction of the slider body 10, the inner cavity is respectively provided with a notch 51 for the pull tab 20 to pass through on the side walls of the two sides of the cap 50 in the width direction, each notch 51 is simultaneously communicated with the opening of the inner cavity of the cap 50, and a blocking block 52 is respectively arranged on the groove wall of one side of each notch 51 far away from the slider body 10, specifically, the blocking block 52 is integrally connected with the cap 50, the spring leaf 40 is blocked by the blocking block 52, a groove 53 is respectively formed between the side wall of the two sides of the cap 50 in the length direction and the corresponding blocking block 52, and the groove 53 can provide enough operating space for the pull tab 20. Through setting up and hiding the dog 52, when carrying out the process of spraying paint, because hiding the dog 52 and blockking, the paint is difficult to flow into the position department between reed 40 and cap 50, and the reed 40 is difficult to be glued or the card post by paint, and the production defective rate is lower relatively.

Preferably, in the present embodiment, the side surfaces of the shielding block 52 at both sides of the cap 50 in the length direction are inclined surfaces or arc surfaces, so that a guiding effect is formed and the operation of the pull tab 20 is smooth. In addition, the pull tab 20 is provided with a through hole 21 matched with the notch 51, a through rod 22 is formed between the through hole 21 and the end face of one end of the pull tab 20 close to the slider body 10, and the distance between the shielding block 52 and the slider body 10 is equal to or slightly larger than the width or thickness of the through rod 22.

The present invention has been described in detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention according to the prior art, and these all belong to the protection scope of the present invention.
