Abstract

The utility model relates to a barrel cover which is a top cover structure of a cotton sliver barrel. The utility model is integrally formed by plastic, the bottom surface of the inner side of the utility model is coated and formed with star-shaped seats at equal intervals, and the bottom surface of the utility model is provided with a clamping sheet for the clamping and the positioning of the top end of a spiral spring. The bottom end of each star shaped seat is convexly extended with a tying snap ring which is used for tying and buckling a ring body of a rope. The spiral spring and the bottom end of the rope are fixedly connected with a chassis, and are integrally sheathed in a barrel body. The utility model is characterized in that both sides of each star-shaped seat made up of metal are respectively extended and convexly provided with a convex wing which is provided with a through hole and is covered on the inside bottom of the top cover; the through holes are filled by the convex wings which are in injection molding, and thus the top cover is tightly, firmly and integrally supported and combined with the star-shaped seats. The utility model is used for the cotton sliver barrel.

Description

The cap structure of sliver can

The utility model relates to bung, refers in particular to textile mills' sliver bung.

Existing sliver can top cover is shown in Fig. 1-5: top cover 10 is combined in spring 20 tops, there is a chassis 30 bottom, 30 on top cover 10 and chassis are to connect to insert in the staving 50 by hawser 40, support by spring, make sliver emersion staving 50 so that take, this top cover has following shortcoming: 1, the several equidistant plastics decks 101 of welding at the bottom of the top cover need other die sinking tool, processing and fabricating cost height; 2, deck 101 has an open slot 102, its inboard upper and lower edge has mutual cooresponding arc recess 103, the elasticity that open slot 102 is slightly expanded, it is affixed with top cover that the ammunition feed spring is sticked in arc recess 103 by open slot, deck 101 causes the disengagement of spring and top cover because of being can lose positioning action behind plastics permanent; 3, there is a setting fastening body 104 the deck bottom, colludes for the ring body 401 of hawser 40 and closes, and button and deck are one-body molded, stretches for a long time when hawser and draws, and setting fastening spare 104 easily broken taking off cause that sliver is crooked to drop, and in a word, the reliability of this top cover is on duty mutually.

The purpose of this utility model provides a kind of cap structure of comparatively failure-free sliver can.

The purpose of this utility model is achieved in that the cap structure of sliver can, and it is integrally moulded, and inside bottom surface is equidistant Overmolded to be had

Type seat, its bottom surface have a clip sheet, set the position for coil spring top card, and each Type seat bottom protrudes out a setting fastening ring, connects fastening for the member ring systems of hawser, and the affixed and whole cover in the bottom of this coil spring and hawser and chassis is inserted in the staving; It is characterized in that: this is metal

Each extends type seat dual side-edge and to be convexly equipped with a protruding wing, and the protruding wing is provided with perforation and is coated on the top cover inside bottom surface, and perforation is filled up for the protruding wing of injection mo(u)lding, make top cover and

The type seat is tightly pulled and firmly is combined as a whole.

Above-mentioned design, it is convenient that top cover is made, and is difficult for throwing off with coil spring, supports steadily firmly, reached and used comparatively failure-free effect.

Be described further again below by accompanying drawing, embodiment.

Shown in Fig. 6-7: the utility model is integrally moulded, and inside bottom surface is equidistant Overmolded to be had Type seat 11, its bottom surface have a clip sheet 12, set the position for coil spring 2 top cards, and each Type seat 11 bottoms protrude out a setting fastening ring 13, are to connect fastening for the ring body 41 of hawser 4, and the bottom of this coil spring 2 and hawser 4 and chassis 3 affixed and whole covers are inserted in the staving 5; It is characterized in that: this is metal

Each extends shape seat 11 dual side-edges and to be convexly equipped with a protruding wing 14, and the protruding wing 14 is provided with perforation 15 and is coated on top cover 1 inside bottom surface, and makes perforation 15 for the protruding wing 15 of injection mo(u)lding fills up, make top cover 1 and

Type seat 11 is tightly pulled and firmly is combined as a whole.Shown in Fig. 8-11: use manufacturing of the present utility model be achieved in that with Type seat 11 places in the injection mould, makes it equidistantly take shape in top cover 1 inside bottom surface, and its protruding wing 14 coated and adhere on top cover 1 bottom surface, and a plurality of perforation 15 on the protruding wing 14 are filled up by the plastic cement of top cover 1 integrated injection molding.During use, with inserting of coil spring 2 tops

It is affixed with chassis 3 that the clip sheet 12 of type seat 11 and downward bending clip sheet 12 make coil spring 2 snap in clip sheet 12, hawser 4 bottoms also with chassis 3 windings, ring body 41 direct hooks are on setting fastening ring 13, and integral body is inserted in the staving 5 again, make the elasticity of top cover 1 mat coil spring 2 be cushioned the carrying sliver.The utility model has the advantages that: 1

Type seat and top cover are one-body molded, and be easily manufactured, and cost reduces; 2, the clip sheet is down curved, prevents that coil spring from deviating from, and clip is firm; 3, protrude out a setting fastening ring system and connect hawser, the setting fastening ring, be contained on the top cover securely, and carry helical spring strength, easy fracture not, the reliability of service and the life-span of having improved top cover greatly.
