Description

Technical Field

[0001] This utility model relates to the field of nonwoven bag technology, specifically to a high-strength nonwoven bag. Background Technology

[0002] Non-woven bags, as an environmentally friendly and practical packaging container, are widely used in daily life and business activities. However, traditional non-woven bags, due to their fixed shape and large volume, often take up considerable space when stored and carried, causing inconvenience to users. This inconvenience is particularly noticeable when people need to carry multiple non-woven bags or when storage space is limited. Utility Model Content

[0003] In view of the problems existing in the above-mentioned high-strength nonwoven bags, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a high-strength nonwoven bag, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength nonwoven bag includes a bag body and a storage tube. The storage tube is located below the bag body and has a strip-shaped opening at its upper end. The lower end of the bag body extends into the storage tube. A winding rod is rotatably mounted in the middle of the storage tube. The lower end of the bag body is fixedly connected to the winding rod. A groove is provided at one end of the storage tube, and one end of the winding rod extends into the groove. A limiting mechanism is provided inside the groove to restrict the rotation of the winding rod.

[0007] Preferably, the limiting mechanism includes a limiting wheel and a locking block. The limiting wheel is disposed inside the groove and fixedly connected to one outer end of the winding rod. The sidewall of the limiting wheel is provided with multiple locking slots arranged in a circular array around the winding rod as the axis. Two fixing blocks are fixedly disposed on the upper side inside the groove. A rotating rod is rotatably disposed between the two fixing blocks. A rotating block is fixedly sleeved on the rod wall. The locking block is fixedly disposed on the lower side of the rotating block and engages with the corresponding locking slot.

[0008] Preferably, a torsion spring is movably sleeved on the wall of the rotating rod, and the two ends of the torsion spring are respectively fixedly connected to the corresponding rotating rod and the fixing block.

[0009] Preferably, a spring is movably sleeved at one end of the winding rod, one end of the spring is fixedly connected to the winding rod, and the other end of the spring is fixedly connected to the inner wall of the storage tube.

[0010] Preferably, the main body of the bag is a high-strength non-woven bag.

[0011] Preferably, handles are fixedly provided on both sides of the upper surface of the main body of the bag.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model overcomes the elastic force of the torsion spring, rotates the rotating rod, and causes the rotating block to drive the locking block to rotate, causing the locking block to leave the locking slot, thereby releasing the restriction on the winding rod. The elastic force of the spring can drive the winding rod to rotate, and the lower end of the storage bag is wound up, which can reduce the size of the main body of the bag and make it convenient to carry.

[0014] 2. This utility model uses high-strength non-woven fabric to make the main body of the bag, which gives the bag good wear resistance and thus a long service life. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a high-strength nonwoven bag.

[0024] Reference Figure 1-4 A high-strength nonwoven bag includes a bag body 1 and a storage tube 3. The storage tube 3 is located below the bag body 1. The bag body 1 is a high-strength nonwoven bag with good wear resistance. Handles 2 are fixedly provided on both sides of the upper surface of the bag body 1 for easy carrying. The upper end of the storage tube 3 has a strip-shaped opening. The lower end of the bag body 1 extends into the interior of the storage tube 3. A winding rod 4 is rotatably provided in the middle of the storage tube 3. The lower end of the bag body 1 is fixedly connected to the winding rod 4. A groove is provided at one end of the storage tube 3. One end of the winding rod 4 extends into the interior of the groove. A limiting mechanism is provided inside the groove to restrict the rotation of the winding rod 4.

[0025] Reference Figure 1-4 The limiting mechanism includes a limiting wheel 6 and a locking block 10. The limiting wheel 6 is located inside the groove and is fixedly connected to one end of the outer side of the winding rod 4. The side wall of the limiting wheel 6 is provided with multiple locking slots arranged in a ring array around the winding rod 4. Two fixing blocks 7 are fixedly installed on the upper side inside the groove. A rotating rod 11 is rotatably installed between the two fixing blocks 7. A rotating block 9 is fixedly sleeved on the rod wall of the rotating rod 11. The locking block 10 is fixedly installed on the lower side of the rotating block 9 and engages with the corresponding locking slot. A torsion spring 8 is movably sleeved on the rod wall of the rotating rod 11. The two ends of the torsion spring 8 are fixedly connected to the corresponding rotating rod 11 and the fixing block 7, respectively. In the natural state, the elastic force of the torsion spring 8 will cause the rotating rod 11 to drive the rotating block 9 to rotate, so that the locking block 10 engages in the locking slot.

[0026] Reference Figure 1-4 One end of the winding rod 4 is movably sleeved with a spring 5. One end of the spring 5 is fixedly connected to the winding rod 4, and the other end of the spring 5 is fixedly connected to the inner wall of the storage tube 3. In a natural state, the elastic force of the spring 5 will drive the winding rod 4 to rotate and wind up the main body 1 of the bag.

[0027] In this utility model, when it is necessary to reduce the size of the cloth bag for carrying, the rotating rod 11 is rotated to overcome the elastic force of the torsion spring 8. The rotating rod 11 drives the rotating block 9 to rotate synchronously, so that the locking block 10 is disengaged from the locking groove of the limiting wheel 6, and the rotation restriction on the winding rod 4 is released. At this time, the spring spring 5 inside the storage tube 3 releases its elastic force, which drives the winding rod 4 to rotate. The lower end of the cloth bag body 1 is gradually wound up on the winding rod along the strip opening of the storage tube 3. The height of the cloth bag body 1 is shortened accordingly, and the overall volume is greatly reduced, making it easy to put into a bag or carry with you.

[0028] To unfold the bag for loading, simply hold the handle 2 and pull the bag body 1 upwards. The bag body 1 drives the winding rod 4 to rotate in the opposite direction, and the spring 5 is twisted and stored. When the bag is unfolded to the required length, release the rotating rod 11. The elastic force of the torsion spring 8 pushes the rotating block 9 to reset, and the locking block 10 re-engages into the corresponding slot of the limiting wheel 6, locking the position of the winding rod 4 and preventing the bag body 1 from shrinking on its own.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
