Abstract

The utility model relates to a device for zipping jacket forepart, comprising a hinge pin arranged on the presser foot of a sewing machine, a bending frame arranged on the hinge pin, a gland nut arranged on the bending frame for pressing the hinge pin, and a baffle ruler arranged at one end of the bending frame, wherein a tension spring is arranged between the hinge pin and the baffle ruler; one end of the baffle ruler is hinged with the bending frame and can rotate vertically along the bending frame; and the other end of the baffle ruler is provided with two U-shaped limiting grooves in an abreast way. In the utility model, through manufacturing the tail part of the baffle ruler and the bending frame into hinge connection, the expansion of the tension spring leads the U-shaped limiting grooves to be capable of rising and falling along with the cloth, the U-shaped limiting grooves can be automatically uplifted when coming across the zipper head part so as to avoid the zipper head, the zipper is not blocked when passing through the tuck position, the product quality is ensured, and the gland nut on the bending frame can tightly press against the hinge pin when being screwed off to position the baffle ruler in a left and right way; and the device improves the production efficiency, saves time and effort, and can meet the demand of mass production.

Description

The device of slide fastener on a kind of upper garment front part of a Chinese robe or jacket

Technical field

The utility model relates to the device of slide fastener on a kind of upper garment front part of a Chinese robe or jacket.

Background technology

At present in military raincoat production process, on the raincoat Qianmen during slide fastener, slide fastener shuts the door apart from the clean limit of the front part of a Chinese robe or jacket and apart from the front part of a Chinese robe or jacket all dimensional requirement, need manual line could ensure that slide fastener is apart from the clean limit of the front part of a Chinese robe or jacket and apart from the front part of a Chinese robe or jacket unanimity that shuts the door during operation, but it is more through operation in the practical operation because of institute, it is unclear to print by hand, causes unstable product quality, and production efficiency is low; Secondly needed slider of zipper fastener when going up slide fastener, and slider of zipper fastener is not smooth when crossing tuck position, Qianmen, it is serious to be obstructed, and normal style retaining chi can not satisfy requirements of large-scale production.

The utility model content

The technical problem that the utility model solved provides a kind of simple in structure, accurate positioning, the device of slide fastener on the upper garment front part of a Chinese robe or jacket of high efficiency.

The utility model adopts following technical scheme:

The utility model comprises the bearing pin that is arranged on the sewing-machine foot, be arranged on curved frame on the bearing pin, be arranged on and compress the clamp nut of bearing pin on the curved frame and be arranged on retaining chi on curved frame one end, between bearing pin and retaining chi, be provided with extension spring, described retaining chi one end and curved frame are hinged, and can rotate up and down along curved frame, the retaining chi other end has been arranged side by side two U type stopper slots.

The utility model good effect is as follows:

The utility model is made into hinge-type with curved frame and is connected by keeping off the chi afterbody, the flexible of extension spring can rise and fall the U type stopper slot on the retaining chi with cloth, running into the slider of zipper fastener position can lift the U type stopper slot on the retaining chi automatically, dodge slider of zipper fastener, a U type stopper slot of retaining chi front end is the clean limit of the front part of a Chinese robe or jacket fixedly, another U type stopper slot is slide fastener fixedly, to guarantee that when making slide fastener is apart from the clean limit of the front part of a Chinese robe or jacket and consistent apart from the limit that shuts the door, and be not obstructed in the place at the mistake tuck, guarantees product quality, and the clamp nut on the curved frame can hold out against bearing pin when screwing off, make about the retaining chi and locate, increase work efficiency, time saving and energy saving, can satisfy requirements of large-scale production.
