Background
The packaging bag is a bag for packaging various articles, so that the goods are convenient to transport and easy to store in the production flow process. Is widely used in daily life and industrial production. The commercial quality of the package itself is more and more remarkable, and it has become a special product which is no longer attached to the production of commodities, a widely used product in which all commodities are inseparable.
The mill need use the industry wrapping bag when packing the product, and the receipts of present industry wrapping bag sack restrict and do not have the function of locking, leads to environmental protection industry wrapping bag when using, appears the open situation of sack easily, causes article to drop out in the industry wrapping bag and produces the damage, has reduced the practicality of industry wrapping bag.
The patent application number is "CN200920043232. X", and the patent name is "single well-drawn rope threading wrapping bag" which includes the bag body and stay cord, and the stay cord is established at the open end of the bag body. A pull rope containing bag is arranged at the opening end of the bag body, and the pull rope is arranged in the pull rope containing bag; the opening is arranged on the pull rope storage bag, and when the bag is used, the pull rope is pulled out from the opening, but the bag opening can be tightened only by manually knotting the pull rope by a user.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: in order to overcome the problem that the bag opening of an environment-friendly industrial packaging bag is easy to open due to the fact that the existing bundling rope of the bag opening of the industrial packaging bag in the prior art does not have a locking function, a pulling buckle for bundling the bag opening is provided.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a zipper for a bundling rope at a bag opening of a packaging bag comprises a sleeve shell and a buckle body, wherein the buckle body is slidably mounted in a cavity of the sleeve shell, inclined planes which are inclined inwards from top to bottom are arranged on the left side and the right side of the inner wall of the cavity of the sleeve shell, the buckle body comprises a push-pull part, a fixing part and two elastic arms, the bottom surface of the push-pull part is fixedly connected with the top surface of the fixing part, the elastic arms are symmetrically arranged on the left side and the right side of the push-pull part, the bottom ends of the elastic arms are fixedly connected with the top surface of the fixing part, and the maximum width L1 of the fixing part is larger than the minimum gap L2 between the two inclined planes;
this receipts are restrainted rope one end and are passed the cavity of cover shell and detain the clearance between the body left side, should receive the rope other end and pass the cavity of cover shell and detain the clearance between the body right side, make the knot body can press from both sides tight receipts and restraint the rope after removing through the cooperation of inclined plane and fixed part in the cover shell, and through the installation of the elastic arm, open at the wrapping bag sack and make the receipts bundle rope take out, receive the rope and can make the elastic arm open and form the auto-lock, make the receipts bundle rope can not take out or be difficult to take out.
In order to solve the problem that the body slides easy slippage in the cover shell, further include it has the stopper to detain the protrusion on the body, set up the spacing hole that extends along vertical direction on the cover shell, stopper slidable mounting is in spacing downthehole, thereby the removal scope of the body is detained in the cooperation restriction through stopper and spacing hole, prevents to detain the body slippage.
In order to solve the problem that the fixed part and the inclined plane centre gripping are taken up the rope insecure, lead to its easy slippage, further include the isosceles trapezoid structure that the fixed part is invertd, just the side of fixed part all has first flank of tooth, thereby prevents to take up the rope slippage through the first flank of tooth increase receipts bundle rope and the frictional force between the fixed part.
In order to solve when receiving the binding rope and being extracted, the power to the elastic arm application of force is not enough its unable open problem, further include the top of elastic arm has the second flank of tooth, thereby increases the contact degree of receiving the binding rope and elastic arm through the second flank of tooth and guarantees to receive the binding rope and can drive the elastic arm and outwards open thereby locking and receive the binding rope and make it can't take out at the in-process of taking out.
In order to solve the problem that the rope of restricting of receipts wearing and tearing are serious and easy skew at the pull in-process, further include the breach that is used for holding the rope of restricting of receipts is all offered to the bottom both sides of cover shell, and the existence of breach makes the rope of restricting of receipts can take place the skew or remove repeatedly the rope of restricting of receipts in the removal restriction of the pull in-process on the one hand to the broken condition of rope wearing and tearing of restricting of reducing takes place.
The utility model has the beneficial effects that: according to the draw buckle for the bundling rope at the bag opening of the packaging bag, the buckle body can clamp the bundling rope after moving through the matching of the inclined surface in the sleeve and the fixing part, and the elastic arm is installed, so that when the bag opening of the packaging bag is opened to draw out the bundling rope, the bundling rope can be opened to form self-locking, and the bundling rope cannot be drawn out or is not easy to draw out.
