Description

Technical Field

[0001] The utility model relates to the technical field of sealed bags, in particular to an explosion-proof edge-sealing zipper for a fresh-keeping bag and a bag body thereof. Background Art

[0002] Fresh-keeping bags are generally used to hold food, and can prevent the moisture contained in the food from flowing out of the fresh-keeping bag and contaminating the refrigerator or other food. Therefore, most existing fresh-keeping bags are made of plastic materials with good waterproof performance. In order to facilitate the removal of food inside the fresh-keeping bag, a sealing zipper is provided at the opening of the fresh-keeping bag. However, the existing explosion-proof sealing zipper of the fresh-keeping bag and the bag body still have certain defects during use;

[0003] For example, a zipper assembly and a fresh-keeping bag provided with the zipper assembly are proposed in the application number CN201220728817.7. The zipper assembly includes a slider and a zipper; the slider includes an opening block, two limiting plates and a connecting block; the two limiting plates are arranged in parallel on both sides of the connecting block and connected to the connecting block; the opening block is located between the two limiting plates and connected to the connecting block; two limiting blocks are arranged on the side of the two limiting plates away from the connecting block, and the limiting blocks respectively arranged on the two limiting plates correspond to each other and are arranged relatively; a closing strip is also arranged on each of the two limiting plates; the two closing strips are arranged relatively; the zipper includes two single chains; two toothless hooks are arranged side by side on each single chain; the toothless hooks respectively arranged on the two single chains cooperate with each other, and in actual use, the zipper assembly uses the method of mutually buckling the toothless hooks to achieve the sealing of the fresh-keeping bag mouth, but sealing only by this method will easily cause the zipper assembly to burst open under tension, reducing the explosion-proof effect.

[0004] Therefore, we propose a fresh-keeping bag explosion-proof edge-sealing zipper and a bag body thereof to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide an explosion-proof edge-sealed zipper for a fresh-keeping bag and a bag body thereof, so as to solve the problem in the background art that the existing edge-sealed zipper is easily exploded due to tension and reduces the explosion-proof effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an explosion-proof edge-sealing zipper for a fresh-keeping bag and a bag body thereof, comprising a fresh-keeping bag body, a first positioning edge and a second positioning edge,

[0007] The bottom of the fresh-keeping bag body is fixedly connected with a bottom sealing edge, the top of the fresh-keeping bag body is fixedly connected with an upper connecting edge, the top of the upper connecting edge is symmetrically distributed with a first positioning edge and a second positioning edge, and both sides of the fresh-keeping bag body, the inside of the bottom sealing edge, both ends of the upper connecting edge, both ends of the first positioning edge and both ends of the second positioning edge are all fixedly connected with the reinforcement strip;

[0008] A clamping mechanism is symmetrically installed inside the first positioning edge;

[0009] A snap-fit ​​mechanism is symmetrically installed inside the second positioning edge;

[0010] The outer sides of the first positioning edge and the second positioning edge are slidably connected with an edge sealing mechanism.

[0011] Preferably, the clamping mechanism includes a positioning strip symmetrically fixedly installed inside the first positioning edge, a first clamping groove is opened at the inner end of the positioning strip, edging is fixedly installed on both sides of the inner end of the positioning strip, and a first clamping strip is fixedly installed at the inner end of the edging.

[0012] Preferably, the first card slot is arranged in a "T"-shaped structure, and the edge binding and the first card strip are arranged in an integrated structure.

[0013] By adopting the design of the above structure, the symmetrical setting of the snap-fitting mechanism can cooperate with the snap-fitting mechanism to double-seal the opening of the fresh-keeping bag, thereby avoiding the problem of single-layer sealing being prone to bursting. At the same time, the first snap-fitting groove and the first snap-fitting strip can be doubly snap-fitted with the snap-fitting mechanism, which is conducive to structural explosion-proof treatment and improves the explosion-proof effect of the explosion-proof edge sealing zipper of the fresh-keeping bag and its bag body.

[0014] Preferably, the locking mechanism includes a connecting strip symmetrically fixedly installed inside the second positioning edge, a second clip strip is fixedly installed on the inner end of the connecting strip, a third clip strip is fixedly connected to the inner end of the second clip strip, and the second clip strip and the third clip strip are both arranged in a "T"-shaped structure.

[0015] By adopting the above-mentioned structural design, the second card strip and the third card strip in the locking mechanism can form a double locking connection with the first card slot and the first card strip in the snap-fitting mechanism, which is beneficial to improving the connection stability between the snap-fitting mechanism and the locking mechanism, and further improving the explosion-proof effect of the explosion-proof edge sealing zipper of the fresh-keeping bag and its bag body.

[0016] Preferably, the edge sealing mechanism includes a slide buckle, the outer rings of the first positioning edge and the second positioning edge are slidably connected with the slide buckle, the interior of the slide buckle is symmetrically provided with pressing grooves, a connecting shaft is installed on the top of the slide buckle, the outer ring of the connecting shaft is provided with a rotating wheel, and a seam block is fixedly connected to one side of the rotating wheel.

[0017] Preferably, the rotating wheel and the splitting block are rotatably connected with the sliding buckle via a connecting shaft, and the splitting block is designed in a triangular structure.

[0018] The above-mentioned structural design allows the edge sealing mechanism to be located at the sealed connection at one end of the first positioning edge and the second positioning edge when the seal is formed between the two, which can effectively prevent the edge sealing mechanism from blocking the snap connection between the snap connection mechanism and the snap mechanism, thereby facilitating improving the sealing completeness of the first positioning edge and the second positioning edge, and improving the sealing effect of the explosion-proof edge sealing zipper of the fresh-keeping bag and its bag body.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the explosion-proof edge-sealed zipper of the fresh-keeping bag and the bag body thereof;

[0020] 1. The strengthening strip can strengthen the two sides and the bottom sealing edge of the fresh-keeping bag body after sealing, so as to effectively prevent the fresh-keeping bag body from bursting. The clamping mechanism and the clamping mechanism symmetrically arranged inside the first positioning edge and the second positioning edge can double-seal the opening of the fresh-keeping bag body, which is conducive to preventing the other set of clamping mechanism and the clamping mechanism from continuing to seal the opening of the fresh-keeping bag body when a single set of clamping mechanism and the clamping mechanism bursts. The multiple clamping of the clamping mechanism and the clamping mechanism structure improves the explosion-proof effect of the explosion-proof edge sealing zipper of the fresh-keeping bag;

[0021] 2. When the edge sealing mechanism slides on the first positioning edge and the second positioning edge, the clamping mechanism and the locking mechanism can be clamped in an extrusion manner, and when the opening of the fresh-keeping bag body is sealed, the edge sealing mechanism can be located at a sealing position at one end of the first positioning edge and the second positioning edge, which is beneficial to prevent the edge sealing mechanism from blocking the connection between the clamping mechanism and the locking mechanism and failing to ensure complete sealing. At the same time, the clamping of the clamping mechanism and the locking mechanism can be split by rotating the splitting block, and then the sliding of the locking mechanism can realize the opening process after sealing, thereby improving the sealing effect of the explosion-proof edge sealing zipper of the fresh-keeping bag and its bag body.

The design of the above structure enables the reinforcing strip 6 to respectively strengthen the sealing parts of the fresh-keeping bag body 1 on both sides, the sealing parts of the bottom sealing edge 2, the sealing parts of the two ends of the upper connecting edge 3, and the sealing parts of the first positioning edge 4 and the second positioning edge 5, thereby preventing the sealing parts of the fresh-keeping bag body except the opening from separating and bursting, thereby improving the explosion-proof effect of the fresh-keeping bag body.

[0030] A clamping mechanism 7 is symmetrically installed inside the first positioning edge 4, and the clamping mechanism 7 includes a positioning strip 701 symmetrically fixedly installed inside the first positioning edge 4, and a first clamping groove 702 is opened at the inner end of the positioning strip 701, and the first clamping groove 702 is arranged in a "T"-shaped structure. Edge wrapping 703 is fixedly installed on both sides of the inner end of the positioning strip 701, and a first clamping strip 704 is fixedly installed at the inner end of the edge wrapping 703, and the edge wrapping 703 and the first clamping strip 704 are arranged in an integrated structure. A clamping mechanism 8 is symmetrically installed inside the second positioning edge 5, and the clamping mechanism 8 includes a connecting strip 801 symmetrically fixedly installed inside the second positioning edge 5, and the connecting strip 80 1 is fixedly installed with a second clamping strip 802, and the inner end of the second clamping strip 802 is fixedly connected with a third clamping strip 803, and the second clamping strip 802 and the third clamping strip 803 are both arranged in a "T"-shaped structure. The design of the above structure enables the first clamping groove 702 to be clamped with the third clamping strip 803 when the clamping mechanism 7 is sealed and connected with the clamping mechanism 8, and the edge 703 can cooperate with the first clamping strip 704 to be clamped with the openings on both sides of the second clamping strip 802, which is conducive to the structural double clamping connection between the clamping mechanism 7 and the clamping mechanism 8, and improves the stability and explosion-proof effect of the connection between the first positioning edge 4 and the second positioning edge 5.

[0031] The outer sides of the first positioning edge 4 and the second positioning edge 5 are slidably connected with an edge sealing mechanism 9, and the edge sealing mechanism 9 includes a slide buckle 901, and the outer rings of the first positioning edge 4 and the second positioning edge 5 are slidably connected with the slide buckle 901, and the interior of the slide buckle 901 is symmetrically provided with a pressing groove 902, and a connecting shaft 903 is installed on the top of the slide buckle 901, and the outer ring of the connecting shaft 903 is provided with a rotating wheel 904, and a seam block 905 is fixedly connected to one side of the rotating wheel 904, and the rotating wheel 904 and the seam block 905 are rotatably connected to the slide buckle 901 through the connecting shaft 903, and the seam block 905 is designed in a triangular structure.

[0032] Working principle: When using the explosion-proof edge-sealed zipper and the bag body of the fresh-keeping bag, first Figure 1-5As shown, when the opening of the fresh-keeping bag body is sealed, the sliding buckle 901 is pushed so that the pressing groove 902 in the sliding buckle 901 squeezes the positioning strip 701 and the connecting strip 801, so that the positioning strip 701 drives the first clamping groove 702 to engage with the third clamping strip 803, and in the process of engaging, the edge 703 also uses the first clamping strip 704 to engage with the openings on both sides of the second clamping strip 802, so as to complete the sealing of the openings of the first positioning edge 4 and the second positioning edge 5, and when the sealing is completed, the sliding buckle 901 is located at the first positioning edge 4 and the second positioning edge 5. The sealed connection at one end of the edge 5 is opened by rotating the rotating wheel 904 to drive the splitting block 905 to rotate, and then the splitting block 905 will squeeze and split the snap connection between the snap mechanism 7 and the snap mechanism 8 during the rotation process, and then the sliding buckle 901 is pushed to drive the splitting block 905 to continuously split the snap mechanism 7 and the first snap strip 704, thereby completing the opening of the fresh-keeping bag body. It is worth mentioning that the snap mechanism 7 and the snap mechanism 8 in the present application are both soft rubber structures, and the two are snap-connected and separated by the elastic connection of the material itself.
