Description

Technical Field

[0001] This utility model relates to the field of paper bag technology, specifically an environmentally friendly paper bag with replaceable handles. Background Technology

[0002] Paper is a recyclable resource. The raw material for papermaking is mainly plant fiber. In addition to the three main components of cellulose, hemicellulose and lignin, the raw material also contains other components in smaller amounts, such as resin and ash. In addition, there are auxiliary components such as sodium sulfate. Paper bags are a type of everyday product. They are containers for holding objects and are an environmentally friendly product made of paper.

[0003] Traditional paper bags are prone to breakage of the handles after prolonged use. Once the handle breaks, the buckle on the handle cannot be connected and secured to a new handle, rendering the paper bag unusable and resulting in waste. Over time, the edges of the paper bag are bent repeatedly, reducing their strength and causing frequent tearing at the bends. Utility Model Content

One end of each horizontal rib 52 is connected to an edge strip 53, reinforcing the bends at the edges of the paper bag body 1 and reducing tearing at these bends. Several side ribs 54 are fixedly connected to one side of the edge strip 53, increasing the lateral support on both sides of the paper bag body 1. A nylon mesh 55 is connected to the bottom of the vertical rib 51, increasing the strength of the bottom of the paper bag body 1 and preventing objects from falling from the bottom of the paper bag body 1 if it breaks.

[0026] refer to Figure 3 , Figure 4 and Figure 5 As shown, the pressure plate 43, the rubber pad 44, and the toothed plate 45 are all located inside the locking buckle 3. The locking buckle 3 has a groove inside to accommodate the pressure plate 43, the rubber pad 44, and the toothed plate 45. A plurality of toothed slots 6 are also provided on one side of the locking buckle 3 to accommodate the toothed nail 46. The pressure plate 43 and the rubber pad 44 abut against the inner wall of the groove in the locking buckle 3 on both sides. The pressure plate 43 and the rubber pad 44 are slidably connected in the locking buckle 3. The locking bolt 41 is embedded inside the pressure plate 43 and is rotatably connected inside the pressure plate 43. The locking bolt 41 can drive the pressure plate 43, the rubber pad 44, and the toothed plate 45 to move forward, thereby driving the toothed nail 46 to insert into the lifting rope and fix the lifting rope.

[0027] refer to Figure 4 and Figure 6 As shown, the rotating rod 48 is rotatably connected in the positioning block 47. The connecting rod 411, the return spring 412, and the limiting plate 413 are all located inside the rectangular block 49. The connecting rod 411 is slidably connected inside the rectangular block 49. One end of the return spring 412 abuts against the limiting plate 413. The nut on the locking bolt 41 has a positioning hole 7 that matches the shape and size of the insert 414. The insert 414 is embedded in the positioning hole 7. The rotating rod 48 can drive the rectangular block 49 to rotate to the side of the locking bolt 41 and align the insert 414 with the positioning hole 7. The insert 414 can be inserted into the positioning hole 7 to fix the position of the locking bolt 41 and prevent the locking bolt 41 from loosening from the locking buckle 3.

[0028] refer to Figure 2 and Figure 7As shown, the vertical ribs 51, the horizontal ribs 52, the edge strips 53, and the side ribs 54 are all made of rubber-coated webbing. The nylon mesh 55 is disposed between the vertical ribs 51 on both sides of the adjacent paper bag body 1. The vertical ribs 51, the horizontal ribs 52, the edge strips 53, and the side ribs 53 can increase the strength of the paper bag body 1 and reduce the phenomenon of damage to the paper bag body 1. The nylon mesh 55 can increase the strength of the bottom of the paper bag body 1 and prevent objects from falling from the bottom of the paper bag body 1 when the bottom of the paper bag body 1 is damaged.

[0029] Working principle: First, remove the broken lifting rope from the locking buckle 3. Then, place the replacement lifting rope in the groove of the locking buckle 3. Next, rotate the locking bolt 41. The locking bolt 41 pushes the pressure plate 43, rubber pad 44, and toothed plate 45 forward. When the toothed plate 45 moves, it pushes the lifting rope to one end of the groove in the locking buckle 3. As the locking bolt 41 continues to rotate and pushes the toothed plate 45, the toothed nail 46 will press and pierce the lifting rope. Finally, the toothed nail 46 is inserted into the toothed groove 6 to fix the lifting rope. After tightening the locking bolt 41, rotate the rectangular block 49 down. Then, pull the handle 410. The handle 410 pulls the connecting rod 411 and the insert block 414 into the rectangular block 49. When the insert block 414 is no longer blocked by the nut on the locking bolt 41, Rotate the rectangular block 49 to the center of the locking bolt 41, aligning the insert 414 with the positioning hole 7. Finally, release the handle 410, and the return spring 412 pushes the limit plate 413 and the insert 414 back to their original positions, allowing the insert 414 to be inserted into the positioning hole 7. When using the paper bag body 1, the vertical rib 51 can improve the longitudinal support of the paper bag body 1, the horizontal rib 52 can improve the lateral support of the paper bag body 1, the edge strip 53 can reinforce the bends at the edges of the paper bag body 1, reducing the tearing phenomenon at the bends of the paper bag body 1, and the nylon mesh 55 can increase the strength of the bottom of the paper bag body 1 and prevent objects from falling from the bottom of the paper bag body 1 when the bottom of the paper bag body 1 is damaged, thereby improving the strength and service life of the paper bag body 1.
