Abstract

The utility model belongs to a heavy-duty packing buckle for a plastic packing belt, which is made from metallic material through mechanism stamping or a die casting process. The aim of the utility model is to overcome the disadvantages that the operation of the present packing buckle is inconvenient, and the present packing buckle is easy to generate sparks by friction and can be shed to make package baled off. The two ends of the diameter of a buckle body in the shape of a circular disk is cut to linear edges, and other two sides form circular arc shapes. The center of the buckle body is provided with a square notch. The center of one linear edge is provided with a belt feeding opening which is communicated with the square notch. After the package is bundled, sheathing openings of the packing belt are respectively sheathed on the linear edges of the buckle body (namely the pulling edges of the buckle body). The belt feeding opening is covered by one sheathing opening of the packing belt for beautiful prevention for friction. The utility model is used for packing and bundling objects with back expansive force.

Description

Heavy-duty buckle for tying-up belt of plastic package

The utility model relates to the heavy type packing button that a kind of plastic baling band of making through mechanical stamping or extrusion process with metallic material is used.

In the goods operation process, most of object requires packing to tie up, especially resemble Cotton and Linen, have back the object of expansive force after packings such as plastic knitting product, fine hair and hide are tied up, in the packing operation process, adopt of fine quality attractive in appearance, easy to operate tie up even more important.Because it is bigger that above-mentioned object is tied up back time expansive force in packing, requires the place of tying up that bigger bundle power must be arranged.Along with in the goods operation process packing being tied up improving constantly of requirement, present most of above mentioned goods packing is tied up and is generally used plastic baling band alternative metals strap, and its requirement of strength should be not less than metal baling strip, and the strap that this intensity ratio is bigger belongs to heavy strap.Tying up to packing knotting of the joint of the heavy strap of plastics made troubles, and existing employed heavy packing is detained or Fastener mainly contains two kinds: the one, and adopt knotting machinery to band together strap two statures with the metal iron plate; The 2nd, adopt metal packaging buckle with two garden axles, the former is complicated operation when tying up, and employed metal iron plate easily gets rusty and influences the anti-power And that draws and pollute object, and cumbersome when unpacking, and is unfavorable for reclaiming and uses.The latter does not have fixation because employed two axles are through respectively in the running-on at strap two ends, and loose or dislocation causes the Bales Off loss easily.In addition, the common drawback of above-mentioned two kinds of buttons of packing is owing to its material especially structural reason, in transportation, can produce spark when harder article such as other metals of buckle surface contact rub, and causes fire.

Goal of the invention of the present utility model is to overcome that the packing button that adopts when existing plastic baling band packing is tied up exists ties up operation inconvenience, dirty cargo easily gets rusty, can become flexible Bales Off, and packing button is difficult for recovery and shortcoming such as uses again, seeks a kind of novel structure of design and manufacture, and is elegant in appearance, easy to use, it is low to manufacture cost, and stretching resistance is strong, and the plastic baling band that pollutes object that is difficult for getting rusty is detained with heavy packing.

In order to realize the foregoing invention purpose, it is that both sides are arc edge, garden through mechanical stamping or extrusion process once-forming that the utility model adopts cold rolling high-test metal sheet material such as high manganese steel, both sides are linear edge in addition, the centre is shaped on the square body platy structure of square notch, the center of a straight line is shaped on a forward (FWD) mouth therein, can allow the two ends running-on of plastic baling band be inserted in packing thus and buckle.Adopt the grinding apparatus polishing after the whole drawing of packing button, produce the spark damage packing material when having avoided friction, then with its plating or be coated with anti-rust paint.When the utility model uses, with plastic baling band two to the certain-length that turns back, the sticking firm And of alignment leaves the long sticking section of 2cm as running-on in the fold position, two running-ons from the forward (FWD) muzzle of packing button on two linear edges that packing is buckled, by packaged object to return expansive force tension bundle firm.

The packing button that the utility model and existing plastic baling band are tied up knot usefulness compares that to have a novel structure simple, elegant in appearance, uses easy to operately, and it is low to manufacture cost, and anti-expanding force is strong, and the pollution that is difficult for getting rusty recyclablely outstanding advantage such as uses again.

Fig. 1 is the structural representation of the utility model.

Enforcement of the present utility model adopts cold rolling high-test metal sheet material such as high manganese steel as raw material, can make through mechanical stamping with sheet material, also can die casting make button 1, its thickness is 2-4mm, the matrix of button 1 is the garden plate-like, promptly be cut into straight line at diameter two ends, the cooresponding string of the length of its straight line and other arc limit, two gardens is isometric, button 1 center is shaped on the square notch 5 that the length of side is 19-21mm, be drawstring limit 4 wherein with the cooresponding breach of two straight line outward flanges limit, being one side of packing back plastic baling band tension, being band buffer edge 3 with cooresponding breach limit, arc edge, two gardens, is that strap is inserted in temporary transient one side that stops of strap in the packing button internal procedure.Be shaped on the wide forward (FWD) mouth 2 of 2-4mm in a linear edge center of button 1, communicate, so that when tying up, the strap running-on enters the packing button with square notch 5.Button 1 is manufactured and is adopted conventional technique for grinding polishing after the shaping again, and then electroplates or be coated with anti-rust paint and get final product.

When the utility model used, with the homonymy doubling respectively of plastic baling band two ends, And was glued together with seccotine earlier, and the long section of 2cm is left in the fold position, and glue is not with as running-on, and the free length of plastic baling band is determined according to the size of packaged object.Earlier with strapper with packing material tie up be compacted to plastic baling band can be to bundle, with strap doubling end inwardly be bundled in packaged on, make the running-on at two ends be inserted in the band buffer edge 3 of button 1 respectively by forward (FWD) mouth 2, then button 1 is rotated an angle of 90 degrees, on the drawstring limit 4 that the strap running-on is transferred to be enclosed within button 1 respectively, unclamp strapper, lean on the expansive force that returns of packaged object to make the plastic baling band tension.At this moment, the forward (FWD) mouth 2 packaged end running-ons of being with on the button 1 cover, and have guaranteed attractive in appearancely and firm, and there is the strap protecting cover in the outside of whole button 1, make it be difficult for contacting with other packings mouthful or other metals and causing friction generation spark.
