Description

Technical Field

[0001] This utility model belongs to the field of nonwoven bag technology, and in particular relates to a nonwoven bag with adjustable shoulder straps. Background Technology

[0002] With increasing environmental awareness, non-woven bags have become widely used in daily life and business due to their reusability, relatively low cost, and ease of processing. Whether used as shopping bags in supermarkets and shopping malls or as a promotional tool by businesses, non-woven bags are ubiquitous and have become an important alternative to traditional plastic bags. Early non-woven bags mostly used fixed-length shoulder straps, which could not accommodate people of different heights and usage habits. Therefore, non-woven bags with adjustable shoulder straps were developed.

[0003] However, existing non-woven bags with adjustable shoulder straps are not easy to ensure that the adjusted shoulder straps remain at a fixed length during use. When walking, going up and down stairs, or taking public transportation, the shoulder straps will keep slipping or getting longer or shorter, requiring users to frequently pull and adjust them by hand, which reduces travel efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a non-woven bag with adjustable shoulder straps. By setting a fixed length part, it solves the problem that existing non-woven bags with adjustable shoulder straps are not easy to ensure that the adjusted shoulder straps maintain a fixed length during use. When walking, going up and down stairs, or taking public transportation, the shoulder straps will keep slipping or getting longer or shorter, requiring users to frequently lift and adjust them by hand, which reduces travel efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a non-woven bag with adjustable shoulder straps, comprising a bag and an adjustment part. The adjustment part is located on the top of the bag, and there are two of them, located on the front and rear sides of the bag respectively.

[0007] Two length-fixing parts are provided, each mounted on one of two adjusting parts; and

[0008] The disassembly and assembly section is provided in two parts, which are located at the bottom of the two adjustment sections respectively, and are used for the connection between the adjustment section and the cloth bag;

[0009] The adjustment section is used to adjust the length of the shoulder strap. After the length adjustment is completed, the length is fixed by the length fixing section. When the adjustment section needs to be replaced, it can be quickly replaced by the disassembly section.

[0010] Furthermore, the adjustment part includes a fixed shoulder strap disposed at the top of the adjustment part, an adjustment shoulder strap disposed above the adjustment part, and an adjustment member disposed between the fixed shoulder strap and the adjustment shoulder strap;

[0011] The fixed shoulder strap is used to support the weight of the bag, and the length of the shoulder strap is determined by the length of the fold.

[0012] Furthermore, the length-fixing section includes a length-fixing component, which is mounted on the adjustable shoulder strap; and

[0013] A guide component, disposed within a fixed-length component, is used to guide the folded portion of the adjustable shoulder strap;

[0014] The fixed-length component is used to fix the adjustable shoulder strap after it has been adjusted by the adjusting component, and the guide component can guide the adjusted shoulder strap after it has been folded in half.

[0015] Furthermore, the detachable part includes a sliding assembly for adjusting the connection between the part and the bag, wherein the sliding assembly on the left side is used to secure the connection between the shoulder strap and the bag, while the sliding assembly on the right side is used to adjust the connection between the shoulder strap and the bag; and

[0016] A disassembly / assembly assembly is mounted on two sliding assemblies.

[0017] Furthermore, the fixed-length component includes a support frame disposed on the adjustable shoulder strap, the outer wall of the support frame having a plurality of anti-slip textures, and a fixing member disposed inside the support frame;

[0018] The anti-slip texture increases the friction between the user's fingers and the support frame when adjusting the shoulder strap length, preventing slippage during adjustment.

[0019] Furthermore, the guiding assembly includes a guide plate fixedly connected to the inner wall of the support frame, and a connecting frame is fixedly connected to the end of the adjusting shoulder strap;

[0020] The guide plate guides the adjusted shoulder strap after folding and restrains the folded end after adjustment. The bottom of the connecting frame is open.

[0021] Furthermore, the sliding assembly includes two connecting frames two fixedly connected to the top of the bag, the two connecting frames two being slidably connected to two connecting frames one respectively, an L-shaped support plate fixedly connected to the front side of each of the two connecting frames one, two guide blocks fixedly connected to the front and rear sides of each of the two connecting frames two, and several guide blocks being slidably connected to the two connecting frames one.

[0022] The guide block provides necessary guidance for the connecting frame when installing the adjustment unit, making the installation and removal of the adjustment unit more convenient.

[0023] Furthermore, the assembly and disassembly assembly includes sliding rods that pass through several L-shaped support plates, with two handles fixedly connected to the front side of each sliding rod, and elastic elements provided on the rear side of each sliding rod.

[0024] When it is necessary to remove the shoulder strap, the user can apply force to the slider by using the handle, which will cause the elastic element to contract and the shoulder strap can be removed.

[0025] Furthermore, the adjusting member includes an adjusting buckle disposed at the end of the fixed shoulder strap, and the end of the adjusting shoulder strap is wrapped around the adjusting buckle;

[0026] The adjusting buckle is used to secure the connection between the shoulder strap and the adjusting shoulder strap. After the adjusting shoulder strap is wrapped around the adjusting buckle, it is folded in half. By pulling the end of the adjusting shoulder strap, the folded length of the adjusting shoulder strap is increased, thereby completing the adjustment of the shoulder strap length.

[0027] Furthermore, the fixing member includes a rotating shaft rotatably connected to the inner wall of the support frame, and a locking block is fixedly connected to the outer wall of the rotating shaft;

[0028] The locking block and the rotating shaft are eccentrically positioned, meaning that with the rotating shaft as the reference, the thickness of the side of the locking block away from the guide plate is greater than the thickness of the side of the locking block closer to the guide plate. Therefore, when the locking block is turned 180° around the rotating shaft, the locking block will fix the adjusting shoulder strap.

[0029] The elastic element includes triangular limiting blocks fixedly connected to the rear side of several sliding rods, springs are sleeved on the outer wall of several sliding rods, the rear side of several springs is fixedly connected to several triangular limiting blocks, and the front side of several springs is fixedly connected to several L-shaped support plates.

[0030] The elasticity of the spring provides the necessary force to secure the shoulder strap, and the removal of the shoulder strap is also made easier by the elasticity of the spring.

[0031] This utility model has the following beneficial effects:

[0032] 1. By setting a fixed length section, when the length of the shoulder strap needs to be fixed, the locking block can be turned to rotate 180° around the pivot. Due to the eccentric setting between the locking block and the pivot, the locking block will fix the folded adjustment of the shoulder strap when the pivot rotates, thereby fixing the length of the shoulder strap. This generates greater friction and squeezing force, effectively preventing the shoulder strap from slipping and ensuring that the length of the shoulder strap remains stable during use. This avoids the shoulder strap from constantly slipping or becoming longer or shorter, requiring the user to frequently pull and adjust it by hand, thus increasing travel efficiency.

[0033] 2. By incorporating a disassembly / removal mechanism, when the shoulder strap needs to be replaced, the handle can be pulled first. The handle will then move the triangular limiting block away from the connecting frame two via a sliding rod. At this point, the fixed shoulder strap and the adjusting shoulder strap can be removed respectively. Then, the new shoulder strap can be taken out and secured to the connecting frame two via the connecting frame one. The guide block will limit and guide the connecting frame one. As the connecting frame one moves downward, the two triangular limiting blocks will move away from each other, thus forcing the two springs to be compressed. When the triangular limiting blocks move to the bottom of the connecting frame two, the two springs will release their elasticity, causing the two triangular limiting blocks to move closer together, thereby securing the fixed shoulder strap and the adjusting shoulder strap respectively. This allows for quick shoulder strap replacement without the need for complicated tools or cumbersome steps. Furthermore, the guide block ensures the accurate position and direction of movement of the connecting frame one during installation, allowing the shoulder strap to be accurately installed on the bag, avoiding installation deviations, and ensuring the stability and performance of the shoulder strap after installation.

[0044] 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.

[0045] Please see Figure 1-6 As shown, this utility model is a non-woven bag with adjustable shoulder straps, including a bag 111 and an adjustment part 1. The adjustment part 1 is located above the bag 111, and there are two of them, located on the front and rear sides of the bag 111 respectively. The adjustment part 1 includes a fixed shoulder strap 112 at its top and an adjustable shoulder strap 113 above it. An adjustment member is provided between the fixed shoulder strap 112 and the adjustable shoulder strap 113. The adjustment member includes an adjustment buckle 114 at the end of the fixed shoulder strap 112, and the end of the adjustable shoulder strap 113 is wrapped around the adjustment buckle 114. The adjustment buckle 114 is used to secure the connection between the shoulder strap 112 and the adjustable shoulder strap 113, and the adjustable shoulder strap 113 is folded after being wrapped around the adjustment buckle 114. Pulling the end of the adjusting shoulder strap 113 increases its folded length, thus adjusting the shoulder strap length. The fixed shoulder strap 112 supports the weight of the bag 111, and the folded length of the adjusting shoulder strap 113 determines the overall length of the shoulder strap. There are two length-fixing parts 2, each mounted on one of the two adjusting parts 1. There are also two disassembly / assembly parts 3, located at the bottom of the two adjusting parts 1, used for connecting the adjusting parts 1 and the bag 111. The adjusting part 1 is used to adjust the shoulder strap length. After adjustment, the length is fixed by the length-fixing parts 2. When the adjusting part 1 needs to be replaced, it can be quickly replaced via the disassembly / assembly parts 3.

[0046] The length-fixing part 2 includes a length-fixing component 21, which is mounted on the adjustable shoulder strap 113; and a guide component 22, which is disposed within the length-fixing component 21 and is used to guide the folded portion of the adjustable shoulder strap 113. The length-fixing component 21 is used to fix the adjustable shoulder strap 113 after adjustment by the adjusting member, and the guide component 22 can guide the folded adjustable shoulder strap 113. The length-fixing component 21 includes a support frame 211 disposed on the adjustable shoulder strap 113. The outer wall of the support frame 211 has several anti-slip textures 212, and a fixing member is disposed within the support frame 211. The anti-slip textures 212 can increase the grip of the user's fingers when adjusting the shoulder strap length. The friction between the support frames 211 prevents slippage during adjustment. The guide assembly 22 includes a guide plate 221 fixedly connected to the inner wall of the support frame 211, and a connecting frame 222 is fixedly connected to the end of the adjustable shoulder strap 113. The guide plate 221 can guide the folded adjustable shoulder strap 113 and restrain the folded end after adjustment. The bottom of the connecting frame 222 is designed with an open end. By setting a fixed length part 2, a large friction and squeezing force can be generated, which can effectively prevent the shoulder strap from slipping and ensure that the shoulder strap length remains stable during use. This avoids the shoulder strap from constantly slipping or becoming longer or shorter, requiring the user to frequently lift and adjust it by hand, thereby increasing travel efficiency.

[0047] The disassembly / assembly unit 3 includes a sliding assembly 31, which is used to adjust the connection between the unit 1 and the bag 111. The sliding assembly 31 on the left side is used to fix the connection between the shoulder strap 112 and the bag 111, while the sliding assembly 31 on the right side is used to adjust the connection between the shoulder strap 113 and the bag 111. The disassembly / assembly unit 32 includes two connecting brackets 311 fixedly connected to the top of the bag 111. The two connecting brackets 311 are slidably connected to two connecting brackets 222. L-shaped support plates 312 are fixedly connected to the front of each of the two connecting frames 221. Two guide blocks 313 are fixedly connected to the front and rear of each of the two connecting frames 211. Several guide blocks 313 are slidably connected to the two connecting frames 222. The guide blocks 313 can provide necessary guidance for the connecting frames 222 when the adjustment part 1 is installed, making the installation and removal of the adjustment part 1 more convenient. The installation and removal assembly 32 includes slide rods 321 that pass through several L-shaped support plates 312. Two handles 322 are fixedly connected to the front of several slide rods 321. Each of the several sliding rods 321 has an elastic element on its rear side. When the shoulder strap needs to be removed, the user can apply force to the sliding rod 321 using the handle 322, causing the elastic element to contract and thus removing the shoulder strap. The elastic element includes triangular limiting blocks 323 fixedly connected to the rear side of each of the several sliding rods 321. Springs 324 are fitted onto the outer wall of each of the several sliding rods 321. The rear sides of the several springs 324 are fixedly connected to the several triangular limiting blocks 323, and the front sides of the several springs 324 are fixedly connected to several L-shaped... The support plate 312 is fixedly connected; the elasticity of the spring 324 provides the necessary elastic force for fixing the shoulder strap, and the removal of the shoulder strap is also made easy due to the elasticity of the spring 324. By setting the disassembly and assembly part 3, the shoulder strap can be replaced quickly. The whole process does not require complicated tools and cumbersome steps. Furthermore, the guide block 313 ensures the accurate position and direction of movement of the connecting frame 222 during the installation process, so that the shoulder strap can be accurately installed on the cloth bag 111, avoiding installation deviation and ensuring the stability and performance of the shoulder strap after installation.

[0048] A specific application of this embodiment is as follows: In use, first, pass the adjusting shoulder strap 113 through the adjusting buckle 114, then pull the end of the adjusting shoulder strap 113 until it is adjusted to the desired angle. At this time, move the support frame 211 to the position of the end of the adjusting shoulder strap 113, then pass the end of the adjusting shoulder strap 113 through the support frame 211 and through the gap between the locking block 214 and the guide plate 221. Then, bend the locking block 214 to rotate it 180° around the rotating shaft 213. Due to the eccentric setting between the locking block 214 and the rotating shaft 213, the locking block 214 will fix the folded adjusting shoulder strap 113 when the rotating shaft 213 rotates, thereby fixing the length of the shoulder strap. When it is necessary to replace the shoulder strap, the handle can be pulled first. 322, the handle 322 will drive the triangular limiting block 323 to disengage from the connecting frame 2 311 via the slide rod 321. At this time, the fixed shoulder strap 112 and the adjustable shoulder strap 113 will be removed respectively. Then, a new shoulder strap will be taken out and locked onto the connecting frame 2 311 via the connecting frame 1 222. At this time, the guide block 313 will limit the connecting frame 1 222 and provide guidance for it. When the connecting frame 1 222 moves downward, the two triangular limiting blocks 323 will move away from each other, thereby forcing the two springs 324 to be compressed. When the triangular limiting block 323 moves to the bottom of the connecting frame 2 311, the two springs 324 will release their elasticity, causing the two triangular limiting blocks 323 to move closer to each other, thereby locking the fixed shoulder strap 112 and the adjustable shoulder strap 113 respectively.
