Description

A kind of packing snap close

(1) technical field

The utility model is a kind of auxiliary implement of tying up apparatus, particularly relates to a kind of snap close that the packing tape to banding machine steps up.

(2) background technology

Known, generally in bundle and package, all use compress, will be tied thing with strap and tie up, unlikely loose in storing and transporting.In order to ensure solid to goods bundling, through to patent and non-patent technology retrieval, invent and on strapper, do research and improvement per capita, on strapper, increase securing device and mechanism, action.There is its preceence in such mechanism, makes to tie up more solidly, is difficult for unclamping.But it also has limitation, because, still there is not such device on the utensil tying up of many users' uses, out of reach is tied up tighter requirement, and the improvement improvement of equipment also needs to increase cost.

(3) summary of the invention

The utility model avoid tie up do on the utensil that improvement drops into by way of, look for another way, on the hasp strapping of bale cargo, intend providing a kind of and can be convenient to intert strap and tie up, strap is produced tighten up the snap close of effect.

The purpose of this utility model so realizes.

This packing snap close is by the curved coiled type of a resilient bonding jumper.

This bonding jumper along approximate rectangular track bend around, altogether curvedly produces seven approximate right angle limits, and two aspects about forming around six approximate right angle.Wherein head, two sections square edges of tail are in the top aspect, and are parallel in correspondence with each other; Three sections middle square edges are " U " font arranges, and is arranged in the bottom aspect; Two other square edge criss-cross is connected " U " word of bottom with two square edges on top.

In birds-eye view, upper and lower layer is overlapping substantially to be one approximate rectangular, and in front view, upper and lower two interlayers have certain distance, the centre, and two limits are the Saint Andrew's cross cross-like.

During use, an end coiled annular ring with strap, the center of this annular ring " U " word from the bottom is penetrated, annular ring is built up the outside of double-ply end one side towards " U " word, annular ring is inserted on the square edge of this side of upper strata, again this annular ring is tightened up layback outward, will be below the square edge that the double-ply strap is pressed in this side of bottom " U " word, also promptly be pressed in the packing snap close and the goods that is tied between.

The other end of strap is operated also as above so accordingly.

At this moment, pull the end of strap one end with hand or compress, make strap be wrapped in the periphery of whole goods even, docilely, dragging end of strap then and constantly continuing to exert all one's strength, strap is constantly tightened up, up to tie up firmly with satisfaction till.

Because the end of strap is to be pressed between packing snap close and the goods, and the force direction that is subjected to of packing snap close " U " word is meant to goods, and therefore the strap end that is clipped in therebetween is can be not loose.

Simultaneously strap passed through again lower floor's square edge and upper strata square edge around, under the elastic reaction of middle two Saint Andrew's cross bonding jumpers, make strap be in tight state all the time, more can not produce the situation that nature is relaxed.

This utensil structure is simple, ties up conveniently, and predetermincd tension is strong, is difficult for loose.

Because the assortment of article that is tied, various informative, the elastic force of its recovery is also different, for example ties up the metal steel cylinder and ties up clothes, and is just not necessarily suitable with same above-mentioned hasp.Self does not have elasticity steel cylinder, needs hasp that certain elasticity is arranged, and the clothes article, itself is flexible, does not need hasp that big elasticity is arranged, and for this reason, in technique scheme, has increased elastic limit device.

This device is realized by following structure.Between upper layer header, two sections square edges of tail, the side place near Saint Andrew's cross is provided with an inhibiting device, and this inhibiting device is made up of a spacing top and spacing screw rod, and two parts are separately fixed on head, two sections square edges of tail, and the position is corresponding mutually.Spacing top is a hollow tubular, is enclosed within the head of spacing screw rod, and both can axially move mutually; Stop nut is arranged on screw rod, change the position of stop nut on screw rod, the distance that can place restrictions on spacing top and move mutually with spacing screw rod has also promptly been placed restrictions on the distance that upper layer header, two sections square edges of tail move.

In the use, when elasticity of demand is big, stop nut is screwed in, promptly strengthen the distance between stop nut and spacing top, make the two right angle bonding jumpers that twined strap under stressing conditions, can produce bigger displacement; On the contrary, when tying up the bigger goods of elasticity own, stop nut can be screwed out, promptly dwindle the distance between stop nut and spacing top, make the two right angle bonding jumpers that twined strap under stressing conditions, allow stop nut and spacing heading joint touch easily, and can not continue to produce displacement again, increased the rigidity of packing snap close.

So structure make the hasp of the technical program can be suitable for wider bale cargo scope, and unlikely tension is reined in bad goods, or loose excessively, tie up not tight, the loose damage goods that causes.

The technical program is simple in structure, cost is low, easy to operate, be not subjected to placing restrictions on of compress technology, wide accommodation, protection goods ability is strong.
