Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically an adjustable packaging bag. Background Technology

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during the production and distribution process. They are widely used in daily life and industrial production.

[0003] Existing packaging bags are usually of fixed capacity. When there are too many items to package, they need to be packaged separately. This requires a lot of packaging bags and makes it easy to handle the bags later. Also, when the weight of the items in the packaging bags is too large, the bottom of the packaging bags is prone to breaking. Therefore, an adjustable packaging bag is needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses an adjustable packaging bag, including a packaging bag body, wherein a space adjustment mechanism is provided at the bottom of the packaging bag body;

[0006] The space adjustment mechanism includes a folded bag body, which is fixedly connected to the bottom of the inner wall of the packaging bag. A bag bottom is fixedly connected to the bottom of the folded bag body. Connectors are fixedly connected to the middle of the front and rear side walls of the bag bottom. Connecting pieces are rotatably connected to the inner side of each connecting piece. Press buckles are fixedly connected to the top of each connecting piece. Reserved pieces are fixedly connected to the lower middle of the front and rear side walls of the outer side of the packaging bag body. Threaded tubes are fixedly connected to the lower middle of the left and right side walls of the outer side of the packaging bag body.

[0007] As a preferred embodiment of this utility model, each of the threaded tubes is threaded with a screw rod, and each screw rod is fixedly connected to a pressing plate at the end away from the packaging bag.

[0008] As a preferred technical solution of this utility model, the top of the front and rear walls and the left and right sides of the outer side of the packaging bag are provided with connecting straps, and the middle of the outer side wall of the connecting straps is fixedly connected with a pull rope.

[0009] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the middle of the left and right side walls of the bag bottom, and a sliding groove is provided in the middle of the connecting plate.

[0010] In a preferred embodiment of this utility model, the threaded tubes are all disposed inside the slide groove, and the threaded tubes are all in clearance fit with the slide groove.

[0011] In a preferred embodiment of this invention, the diameter of the pressing plate is greater than the width of the groove, and the thickness of the groove is greater than the length of the threaded tube.

[0012] As a preferred embodiment of this utility model, the reserved pieces are all on the same vertical horizontal line as the snap fasteners, and the bottom of the bag is equal in length and width to the packaging bag body.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of adjustable packaging bag allows the bag to expand its capacity by pulling the front and rear snap buttons when the internal space of the bag needs to be adjusted. This releases the restriction on the bottom of the bag by separating the snap buttons from the pre-reserved piece, thereby allowing the folded bag to expand and increase the capacity of the packaging bag. This enables the packaging of more items and improves the space utilization of the packaging bag.

[0015] 2. This type of adjustable packaging bag, after the packaging bag space is adjusted, rotates the left and right pressing plates. During the rotation of the pressing plates, the screw rotates, causing the screw to move into the threaded tube. The movement of the screw drives the pressing plates to move, and during the movement of the pressing plates, the connecting plates on both sides are squeezed, thereby fixing the bottom of the bag, improving the load-bearing capacity of the packaging bag, reducing the possibility of the bottom of the packaging bag leaking, and improving the quality of the packaging bag.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, this utility model provides an adjustable packaging bag, including a packaging bag body 1, and a space adjustment mechanism 2 is provided at the bottom of the packaging bag body 1.

[0024] The space adjustment mechanism 2 includes a folding bag body 5, which can extend or retract, thereby moving the bottom 6 of the bag up and down to adjust the space of the packaging bag body 1. The folding bag body 5 is fixedly connected to the bottom of the inner wall of the packaging bag body 1. The bottom of the folding bag body 5 is fixedly connected to the bottom of the bag body 6. Connecting parts 7 are fixedly connected to the middle of the front and rear side walls of the bottom 6. Connecting parts 7 provide space for the installation of connecting pieces 8. Connecting pieces 8 are rotatably connected to the inner side of the connecting parts 7. Press buckles 11 are fixedly connected to the top of the connecting pieces 8. The connecting pieces 8 cooperate with the press buckles 11. After the press buckles 11 are connected and fixed to the reserved piece 12, the bottom 6 of the bag body 1 can be fixed. Reserved pieces 12 are fixedly connected to the lower middle of the front and rear side walls of the outer side of the packaging bag body 1. Threaded tubes 13 are fixedly connected to the lower middle of the left and right side walls of the outer side of the packaging bag body 1. Threaded tubes 13 provide space for the installation of screws 14.

[0025] The inner side of the threaded tube 13 is threaded with screws 14. The end of the screws 14 away from the packaging bag body 1 is fixedly connected with a pressing plate 15. The top of the front and rear walls and the left and right sides of the outer side of the packaging bag body 1 is provided with connecting straps 3. The middle of the outer side wall of the connecting straps 3 is fixedly connected with a pull rope 4. When the pressing plate 15 moves towards the threaded tube 13, it can push the connecting plate 9 to one side of the packaging bag body 1. The connecting plate 9 is fixed by the threaded tube 13 and the pressing plate 15.

[0026] Connecting plates 9 are fixedly connected to the middle of the left and right side walls of the bag bottom 6. A sliding groove 10 is provided in the middle of the connecting plate 9. Threaded tubes 13 are provided inside the sliding groove 10. The threaded tubes 13 are in clearance fit with the sliding groove 10. The threaded tubes 13 can slide up and down inside the sliding groove 10.

[0027] The diameter of the pressing plate 15 is greater than the width of the slide groove 10, the thickness of the slide groove 10 is greater than the length of the threaded tube 13, the reserved piece 12 is on the same vertical horizontal line as the pressing buckle 11, the bottom of the bag 6 is equal in length and width to the packaging bag body 1, and the bottom of the bag 6 can seal the bottom of the packaging bag body 1.

[0028] Working principle: When it is necessary to adjust the internal space of the packaging bag body 1, pull the front and rear pressing buckles 11 to separate the pressing buckles 11 from the reserved piece 12 and release the restriction on the bottom of the bag 6, so that the folded bag body 5 can be extended to expand the packaging bag's capacity, thereby achieving the function of packaging more objects. After the packaging bag space is adjusted, rotate the left and right pressing plates 15. During the rotation of the pressing plates 15, the screw 14 rotates, thereby moving the screw 14 into the threaded tube 13. The movement of the screw 14 drives the pressing plates 15 to move. During the movement of the pressing plates 15, the connecting plates 9 on both sides are squeezed, thereby fixing the bottom of the bag 6, improving the load-bearing capacity of the packaging bag, and completing the adjustment of the packaging bag space.
