Abstract

The utility model relates to a plastic combination snap ring which is a plastic component used for decorating a cloth ventilating hole. Usually, the surrounding edge of a ventilating hole is decorated by a sewing or hand-embroidering method in a normal time, thereby being slow and not nice. The utility model manufactures a plastic mother ring and a plastic plunger ring by an injection molding method. A main body of the plastic mother ring is shaped as a short pipe, one end of the pipe is equipped with a round swing, and the other end is equipped with steps with equal arc length. Certain distances are arranged among the steps. The plastic plunger ring is shaped as a flat ring, and ring holes are two-grade holes in different sizes. When decorating the cloth ventilating hole, one end of the plastic mother ring with the steps is extended through the ventilating hole; the swing of the mother ring is clung at one side of the surrounding edge of the cloth hole; then one end of the plunger ring with a small plunger ring hole is pressed on a pipe opening of the mother ring with the steps by thumb to give force slightly; the plunger ring can be pressured over the steps on the mother ring easily to be mounted at the pipe of the mother ring, and a plunger ring swing is clung at the other side of the surrounding edge of the ventilating hole; the steps are sunk in one end of the plunger ring with a big plunger ring hole, so as to decorate the surrounding edge of the ventilating hole with fast speed and nice appearance.

Description

Plastics combination clasp

Affiliated technical field

The utility model relates to a kind of plastics combination clasp, and it is the working of plastics that is used for modifying the cloth air vent.

Background technology

People are after having opened air vent on the cloth, and just there is the modification problem in all edges of air vent.Chang Yong method is to modify air vent week edge with the method for sewing or hand-embroidered at ordinary times, to also have a kind of method commonly used be exactly with the similar plastics circumferential weld in hole week edge or be attached on all edges, though these methods can both be modified all edges in hole, but they have a common shortcoming, and the speed of modifying exactly is very slow, and production efficiency is low, and after modifying, outward appearance is more coarse, and is not too attractive in appearance, the necessary improvement.

Summary of the invention

The purpose of this utility model is for people provide a kind of plastics combination clasp, modifies all edges of air vent on cloth with its, and speed not only soon but also attractive in appearance.

The technical scheme of the utility model technical solution problem is to produce a plastic master ring and a plastics trim ring with the method for machining or injection moulding, the main body of plastic master ring is the short tube shape, the plastics pressure ring can be enclosed within on female ring, one end of female endless tube is manufactured with the round width of cloth, the other end is manufactured with the rank that arc length equates, certain interval is arranged between rank and the rank.The plastics trim ring is flat annular, the trim ring hole is the two-stage hole that varies in size, the radius of macropore is slightly larger than the radius of rank arc on female endless tube, the slightly larger in diameter of aperture is in the external diameter of the pipe of plastic master ring, the height of the thickness on rank and trim ring macropore is suitable on female endless tube, and the height on rank is slightly larger than the total backlash size of trim ring hole when cooperating with female endless tube face.When modifying the cloth air vent, one end on plastic master endless belt rank is extended through air vent, the width of cloth of mother's ring is attached to the one side at cloth hole week edge, be pressed in the thumb end that the trim ring hole is little then and omit the application of force on the mouth of pipe of female endless belt rank, because the elasticity of plastics is bigger, the distortion on rank can be extended to the interval by the two ends on rank again, trim ring just can be pressed the rank on female ring more like a cork, be enclosed within on the pipe of female ring, and the trim ring width of cloth is attached to the another side at air vent week edge, and the rank on female endless tube then can prop up trim ring, and rank then sink in the big end in trim ring hole, thereby with air vent week the edge fasten and modify, not only fast but also attractive in appearance.

Description of drawings

Accompanying drawing 1 is a combination schematic diagram of the present utility model, and the plastics trim ring makes up with the plastic master ring in a direction indicated by the arrow in the drawings.

Accompanying drawing 2 is partial schematic sectional view of the utility model application example.

The specific embodiment

Accompanying drawing 2 is application examples of the present utility model, and plastic master ring 1 in this example and plastics trim ring 2 are by injection molded.Cloth 3 in this example is the clothes that have the aeration type cap front end face of air vent 4, the mode of modifying hole 4 with the utility model is: an end that mother is encircled 1 band rank 6 extends through hole 4, allow the circle 5 of female ring front end be attached to the outside at 4 all edges, cloth hole, the end that the hole of trim ring 2 is little is pressed on the band rank end face of female ring 1, slightly firmly one press with thumb, the hole of trim ring 2 just can press rank 6 to be enclosed within on the pipe of female ring, 6 on rank can be against the circle of trim ring 27 inner face at all edges in cloth hole 4, rank 6 then sink in the bigger hole of trim ring, thereby all edge in cloth hole 4 is modified, not only fast but also attractive in appearance.

Claims

1, a kind of plastics combination clasp, it is characterized in that: it is made of a plastic master ring and plastics trim ring, the main body of female ring in a tubular form, the plastics trim ring can be enclosed within on female endless tube, one end of pipe has the round width of cloth, there is certain interval on the rank that the other end has arc length to equate between rank and the rank, the height on rank is slightly larger than the total backlash size of trim ring hole when cooperating with female pipe that encircles.

2, plastics combination clasp according to claim 1, it is characterized in that the plastics trim ring is flat annular, the trim ring hole is the different two-stage hole of diameter, the radius of macropore is slightly larger than the radius of rank arc on the plastic master endless tube, the slightly larger in diameter of aperture is in the external diameter of plastic master endless tube, and the thickness on rank is suitable on the height of macropore and the plastic master endless tube.
