Description

Technical Field

[0001] This utility model relates to the field of handle reinforcement technology, and in particular to a woven bag with a handle reinforcement structure. Background Technology

[0002] Woven bags with reinforced handles provide convenient gripping points for handling and are a key component for improving ease of use. The handles are used to strengthen the structure of the woven bag handles, thus providing a stable structural foundation for subsequent storage and handling. This prevents the stitching from loosening or even breaking due to repeated stress. Woven bags with reinforced handles are widely used for cargo transportation and storage.

[0003] To strengthen the woven bag and reinforce the handles, woven bags with reinforced handle structures are needed. Existing woven bags with reinforced handle structures often use widened and thickened webbing and plastic strips for the handles, connected to the bag body via rivets, sewing, and heat fusion. During use, the sewn seams are prone to loosening or even breaking due to repeated stress, and the heat-fused joints can weaken due to material aging. Furthermore, the handles, which extend from the bag fabric, subject the fabric at the connection point to continuous concentrated tension, causing the handles to separate from the bag body. This results in items falling and being damaged during handling, significantly increasing production costs, reducing product quality, and shortening lifespan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a woven bag with a reinforced handle structure, which aims to improve the problem of breakage caused by loose stitches in the prior art.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 An embodiment of this utility model provides: a woven bag with a handle reinforcement structure, including a bag body 1, a handle base 3 fixedly connected to the outer wall of the bag body 1, a groove 4 opened on the inner wall of the handle base 3, a plurality of sliding blocks 5 slidably connected to the inner wall of the groove 4, a connecting rod 6 fixedly connected between adjacent sliding blocks 5, a fixing post 7 fixedly connected to the inner wall of the sliding block 5, a rotating shaft 8 rotatably connected to the inner wall of the fixing post 7, a triangular ring 9 rotatably connected to the inner wall of the rotating shaft 8, a hook 10 slidably connected to the outer wall of the triangular ring 9, a lock 11 rotatably connected to the inner wall of the hook 10, a lifting rope 12 fixedly connected to the top of the outer wall of the hook 10, and a folding mechanism 2 fixedly connected to the inner wall of the handle base 3, the folding mechanism 2 being used to fold and fit the woven bag;

[0032] Specifically, the handle base 3 on the outer wall of the bag body 1 is the core load-bearing component. Its inner wall groove 4 and sliding block 5 form a sliding adjustment structure. Multiple sliding blocks 5 are connected by a connecting rod 6 and can move synchronously along the groove 4 to distribute the force on the handle. The fixed column 7 inside the sliding block 5 supports the rotation of the rotating shaft 8, so that the angle of the triangular ring 9 can be flexibly adjusted. The sliding connection between the triangular ring 9 and the hook 10 can adapt to different force directions. The hook 10 is securely connected to the triangular ring 9 through the locking buckle 11 to prevent it from falling off. The top carrying rope 12 is for hand gripping. When the bag is under load, the pulling force is transmitted to the hook 10 through the carrying rope 12, and then distributed to the sliding block 5 through the triangular ring 9 and the rotating shaft 8. Finally, it is transmitted to the bag body 1 through the handle base 3. The folding mechanism 2 inside the handle base 3 can fold the handle to fit the bag body 1, reducing the space occupied when not in use and achieving portable storage. The overall structure takes into account both load-bearing stability and usage flexibility.

[0033] Please see the appendix Figure 4 Appendix Figure 5 The folding mechanism 2 includes a protective shell 201. The outer wall of the protective shell 201 is fixedly connected to the inner wall of the handle base 3. A spring 202 is fixedly connected to the inner wall of the protective shell 201. A locking tooth 203 is fixedly connected to the outer wall of the spring 202. A crossbar 204 is rotatably connected to the inner wall of the locking tooth 203. A limit shell 205 is fixedly connected to the rear end of the crossbar 204. A ratchet 206 is fixedly connected to the outer wall of the locking tooth 203. A pawl 207 is engaged with the inner wall of the ratchet 206. A knob 208 is fixedly connected to the inner wall of the pawl 207.

[0034] Specifically, the folding mechanism 2 achieves controllable folding and fixing of the handle through the cooperation of ratchet 206 and pawl 207. The protective shell 201 is fixed to the inner wall of the handle base 3 to provide protection for the internal components. The spring 202 pushes the locking tooth 203 to maintain the engagement state. The crossbar 204 passes through the locking tooth 203 and connects to the limiting shell 205 to limit the displacement range of the components. The ratchet 206 rotates with the locking tooth 203 and engages with the pawl 207 to achieve one-way positioning, ensuring that the handle is stable and does not loosen after unfolding. Rotating the knob 208 can drive the pawl 207 to disengage from the ratchet 206 and release the locking state. At this time, the handle can be folded to fit the bag body 1. The spring 202 resets and the auxiliary mechanism locks, achieving stable fixing of the folded state and improving storage convenience.

[0035] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The top of the bag body 1 is fixedly connected to the bag opening 13, the outer wall of the bag opening 13 is fixedly connected to the buckle 14, the inner wall of the reinforcing ring 17 is fixedly connected to the connecting ring 21, the outer wall of the connecting ring 21 is fixedly connected to the inner wall of the reinforcing strip 18, the top of the outer wall of the lifting rope 12 is fixedly connected to the hand guard 15, and the bottom of the bag body 1 is fixedly connected to the pad block 16.

[0036] Specifically, the bag opening 13 at the top of the bag body 1 is closed and opened by the outer wall buckle 14. The buckle 14 can prevent the internal items from falling out when it is fastened. The inner wall connecting ring 21 of the reinforcing ring 17 is fixed to the reinforcing strip 18 to enhance the strength of the stress parts of the bag body 1. The hand guard 15 at the top of the lifting rope 12 increases the contact area of ​​the hand and reduces the pressure during handling. The pad 16 at the bottom of the bag body 1 improves the wear resistance of the bottom and prevents the bottom of the bag body 1 from being damaged by friction when placed, thus extending its service life.

[0037] Please see the appendix Figure 1 Appendix Figure 4 Appendix Figure 5 A reinforcing ring 17 is fixedly connected to the outer wall of the bag body 1, a reinforcing strip 18 is fixedly connected to the outer wall of the bag body 1, a carrying strap 22 is fixedly connected to the outer wall of the bag body 1, the rear side of the carrying strap 22 is fixedly connected to the outer wall of the reinforcing strip 18, a buckle 19 is fixedly connected to the top of the handle base 3, and a slot 20 is opened on the top of the handle base 3.

[0038] Specifically, the reinforcing ring 17 and reinforcing strip 18 on the outer wall of the bag body 1 work together to enhance the overall structural strength of the outer wall of the bag body 1 and distribute the pulling force during handling. The back of the handle strap 22 is fixed to the reinforcing strip 18, providing an additional grip option for handling and sharing the force on the lifting rope 12. The buckle 19 on the top of the handle base 3 corresponds to the slot 20. When the handle is folded, the buckle 19 is inserted into the slot 20 to fix the position of the handle, preventing the handle from loosening and shaking in the folded state and improving the storage stability.

[0039] Working principle: The handle base 3, which is fixedly connected to the outer wall of the bag body 1, provides space for the movement of subsequent components. The groove 4 on its inner wall provides guidance for the multiple sliding blocks 5 that slide on the inner wall. During handling, the lifting rope 12 can rotate freely with the grip angle, avoiding the local torsional stress caused by the traditional fixed lifting rope 12. The connecting rod 6 fixed between the multiple sliding blocks 5 connects the sliding blocks 5 to each other, preventing tilting during the lifting process due to excessive offset angle. The fixed column 7, which is fixedly connected to the inner wall of the sliding block 5, provides a foundation and strengthens the stability of the rotating shaft 8 of the inner wall. The triangular ring 9 that rotates on the inner wall and the hook 10 that slides on the outer wall connect to the lifting rope 12 for easy lifting. The locking buckle 11 that rotates on the inner wall of the hook 10 can fix the hook 10 to prevent it from falling off. At the same time, it can be disassembled for easy storage when not in use. The folding mechanism 2, which is fixedly connected to the inner wall of the handle base 3, is used to fold the handle base 3 to fit the woven bag, making it easier to store and reducing space occupation.

[0040] The folding mechanism 2 includes a protective shell 201, which protects the moving parts inside. A spring 202 and locking teeth 203 fixed on its inner wall are connected by a crossbar 204 that rotates on the inner wall. Multiple locking teeth 203 are mutually locked by the influence of the spring 202 and can be used for folding when not in use. A limiting shell 205 fixed at the rear end of the crossbar 204 is used to connect the handle base 3. Multiple handle bases 3 are connected to each other to achieve the effect of folding and storage. The ratchet 206 fixed on the outer wall of the locking teeth 203 is affected by the inner wall engaging the pawl 207, which can lock and fix it after unfolding to prevent loosening during rotation. The knob 208 fixedly connected to the inner wall of the pawl 207 is used to unlock the ratchet 206 to fold the entire structure.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
