Description

Technical Field

[0001] This utility model relates to the technical field of foldable fabric boxes, specifically a foldable fabric box. Background Technology

[0002] In daily life and storage, folding fabric trunks are widely used due to their ease of storage and space-saving design. Currently, most folding fabric trunks on the market use a metal frame directly supported at the bottom of the trunk for folding and support. However, this structure has significant technical drawbacks: over time, the connection between the metal frame and the trunk body can loosen, and the frame itself lacks structural stability, easily deforming under weight, leading to poor support or even collapse. This not only affects the trunk's usability but may also damage the contents. Furthermore, these trunks lack efficient internal space utilization; the metal frame occupies a large portion of the interior, limiting storage capacity. Additionally, most existing trunks lack a visible design, making it difficult for users to quickly view the contents and causing inconvenience when retrieving items. Utility Model Content

[0003] The purpose of this invention is to provide a foldable fabric box to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a foldable fabric box, comprising a box body, an observation window fixed to the side wall of the box body, support rods symmetrically fixed to the top and bottom of the inner wall of the box body, a sleeve slidably connected to the outer wall of the support rod, a light rod rotatably connected to the inner side of the sleeve, and the inner sides of the light rods on both sides rotatably connected, a groove block fixed to the outer wall of the light rod, and a fixing member provided inside the groove block.

[0005] Preferably, the support rod has an internal cavity, and a top block is fixed inside the cavity. The top block is made of spring sheet material, has a certain elasticity, and its top is trapezoidal.

[0006] Preferably, the observation window is made of transparent plastic.

[0007] Preferably, the fixing member includes a support block, the support block is disposed on the outer wall of the groove block, and the outer wall of the support block is fixed with a clamping plate on both sides.

[0008] Preferably, the groove block has a through hole inside, and the card plate inserted into the through hole can limit the inner side of the light rod.

[0009] Preferably, the outer wall of the card plate is machined with semi-circular protrusions, and the card plate is made of elastic plastic.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] Through the sliding cooperation design of the bare rod, sleeve, and support rod, the case can be conveniently folded and quickly unfolded. When unfolded, the bare rod drives the support rod to open the top and bottom of the case. With the locking plate limiting and fixing the bare rod pivot, and the top block locking and fixing the slot block, the case has reliable structural stability in use, effectively avoiding deformation or collapse. It not only meets storage needs, but also facilitates storage, carrying and storing, greatly improving the product's space utilization and adaptability to usage scenarios.

[0012] The hollow structure formed inside the support rod not only provides reasonable installation space for internal parts and simplifies the overall structural layout, but also does not occupy the effective storage space inside the box, making full use of the internal space of the box; at the same time, the parts are installed in the cavity of the support rod, which facilitates assembly and maintenance and reduces production and maintenance costs.

[0013] The transparent observation window on the side wall of the case is made of transparent plastic with good light transmission, allowing users to clearly observe the arrangement of items inside the case without opening it, making it easy to quickly locate the required items and significantly improving retrieval efficiency. The tight fit between the clamping plate and the slot in the fixing components, through the precisely designed semi-circular protrusion and through hole, achieves precise positioning of the light rod, ensuring the stability and reliability of the case after it is unfolded.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a foldable fabric box technical solution: A foldable fabric box includes a box body 1. An observation window 2 is fixed to the side wall of the box body 1. The observation window 2 is light-transmitting, allowing clear observation of the items inside the box. Support rods 3 are symmetrically fixed to the top and bottom of the inner wall of the box body 1. The support rods 3 ensure stability when supporting the box body and also provide installation space for internal parts. A sleeve 4 is slidably connected to the outer wall of the support rod 3. The gap between the sleeve 4 and the outer wall of the support rod 3 is extremely small, achieving a smooth sliding effect. A smooth rod 6 is rotatably connected to the inner side of the sleeve 4. The smooth rod 6 cooperates with the bearing seat inside the sleeve 4 to achieve flexible rotation. The inner sides of the two smooth rods are rotatably connected. A groove block 7 is fixed to the outer wall of the smooth rod 6. The through hole formed inside the groove block 7 is precisely sized and connects with the card plate 9. The fit is tight. The groove block 7 has a fixing component inside. The support rod 3 forms a cavity inside, and the top block 5 is fixed inside the cavity. The top block 5 is made of spring sheet material and has a certain elasticity. Its top is trapezoidal in shape. The observation window 2 is made of transparent plastic material.

[0022] The fastener includes a support block 8, which is set on the outer wall of the groove block 7. The shape of the support block 8 is designed according to the contour of the outer wall of the groove block 7, and can fit tightly on the groove block 7. The outer walls of the support block 8 are fixed with clamping plates 9. The semi-circular protrusions on the outer walls of the clamping plates 9 are specially designed, and their curvature and size match the inner wall of the through hole of the groove block 7. The groove block 7 forms a through hole. The clamping plates 9 are inserted into the through hole to limit the inner side of the light rod 6. The outer walls of the clamping plates 9 are machined with semi-circular protrusions, and the material of the clamping plates 9 is elastic plastic.

[0023] Working principle: When using a foldable fabric case, the user first pulls the pivot point inside the light rod 6 outwards. Pulling opens the connection between the light rod 6 and the sleeve 4 to the upper and lower sides respectively. At the same time, the support rods 3 on both sides are pushed, which opens the top and bottom of the case 1. When the case 1 is fully opened, the user uses the support block 8 to drive the locking plate 9 into the slot 7. After insertion, the protrusions on both sides of the locking plate 9 are engaged to limit and fix the pivot point of the light rod 6. Then, the user slides the sleeve 4 outwards to both ends of the support rod 3. When the sleeve 4 passes the top block 5, it is pressed down into the support rod 3. When the slot 7 has completely passed the top block 5, the spring plate material properties cause the top block 5 to spring up, and the edge of the top block 5 engages and fixes the slot 7. Then, the user can put the items to be placed inside the case 1. The transparent material of the window 2 allows the user to see through the placement of the items inside, making it convenient to put in and take out.
