Description

Technical Field

[0001] This utility model relates to the field of bag-covered box, specifically a bag-covered box with multi-layer parts storage space. Background Technology

[0002] Collapsible crates are a common type of cargo box used for packaging and transporting goods. They are usually made of wood or other materials and have a collapsible structure around the box to provide support and protection for the goods. They are suitable for transporting various types of goods and usually use cloth bags as linings to divide the internal space.

[0003] Existing bag-type pallet boxes with multi-layer parts storage space mostly use Velcro to fix the cloth curtains. However, frequent opening and closing of the curtains can cause the Velcro to wear out quickly, which can lead to damage, shorten the lifespan of the Velcro, and affect the stability of use. Once the Velcro is worn out, it can no longer effectively fix the curtain, so the Velcro needs to be replaced. However, frequent replacement of Velcro increases the cost of use, and the replacement process is cumbersome, affecting the efficiency of loading, unloading and transporting goods. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a fabric bag cover box with multi-layer parts storage space to solve the technical problem that frequent opening of the fabric curtain will accelerate the wear of the Velcro and thus affect the stability of the fabric curtain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bag-covered box with multi-layer parts storage space, including a base, a box body on the top of the base, a bag installed inside the box body, a curtain installed above the outer surface of the box body, a mounting seat installed on the top of the base by bolts, and a rotating shaft connected inside the mounting seat by a polytetrafluoroethylene bearing, a pressure plate installed on the outer wall of the rotating shaft, and protrusions on both sides of the back of the pressure plate, torsion springs sleeved at both ends of the rotating shaft, one end of the torsion spring being fixedly connected to the inner wall of the mounting seat, and the other end of the torsion spring being fixedly connected to the pressure plate.

[0006] By adopting the above technical solution, the base provides the load-bearing foundation for the overall structure and is used to install the enclosed box body. The enclosed box body forms a storage cavity to accommodate multiple layers of cloth bags, playing an overall protective and support role.

[0007] Furthermore, the top of the enclosure box body is covered with a top cover, and the top of the top cover has multiple positioning grooves.

[0008] By adopting the above technical solution, the top cover can cover the top of the enclosure box body, preventing external impurities from entering the enclosure box through the top of the enclosure box body.

[0009] Furthermore, the bottom of the base is equipped with multiple support feet, and the number of support feet is the same as the number of positioning slots, and the support feet are adapted to the positioning slots.

[0010] By adopting the above technical solution and adapting the support feet to the positioning groove, multiple pallet boxes can be stably stacked (such as multi-layer stacking during workshop storage and logistics transportation).

[0011] Furthermore, the outer surface of the curtain is fitted with a transparent window, which is made of PVC transparent film.

[0012] By adopting the above technical solution, a visual view can be achieved through a PVC transparent window, allowing the interior of the enclosure box to be viewed without opening or closing the curtain.

[0013] Furthermore, both sides of the curtain are wrapped with rubber strips, and the outer surface of the rubber strips has grooves.

[0014] By adopting the above technical solution, the rubber strips enhance the edge strength of the curtain, preventing tearing caused by frequent opening and closing.

[0015] Furthermore, the protrusion is inserted into the interior of the groove, and the protrusion and the groove are adapted to each other.

[0016] By adopting the above technical solution, the "interlocking" fit of the protrusion embedded in the groove can improve the fixing effect of the pressure plate on the curtain, achieve precise positioning, and prevent it from loosening even during transportation vibration.

[0017] Furthermore, the pressure plate is U-shaped and is made of POM material.

[0018] By adopting the above technical solution, the U-shaped structure can be adapted to the width of the curtain to ensure uniform compression. POM material (polyoxymethylene) has high hardness, wear resistance, and self-lubricating properties, making it suitable for pressure plate scenarios with frequent rotation.

[0019] Furthermore, the pressure plate is rotatably connected to the mounting base via a rotating shaft, and the torsion spring is made of 65Mn spring steel with a hardness controlled between HRC42 and 48.

[0020] By adopting the above technical solution, the limitations of the torsion spring material (65Mn spring steel) and hardness (HRC42-48) ensure that the torsion spring has sufficient elasticity (to achieve reliable compression) and is not easy to break (to adapt to high-frequency opening and closing).

[0021] Furthermore, washers are installed on both sides of the interior of the mounting base. The washers are made of rubber material, and the outer wall of the rotating shaft fits against the inner wall of the washers.

[0022] By adopting the above technical solution, the rubber gasket can elastically fit the shaft, thus preventing loosening and reducing the probability of shaft displacement caused by vibration.

[0023] In summary, the present invention has the following main advantages: 1. This utility model replaces the traditional Velcro with a mechanical pressing structure of torsion spring and pressure plate, reducing wear caused by frequent tearing, adapting to high-frequency operation scenarios, and optimizing operation convenience; opening the curtain only requires rotating the pressure plate (to overcome the spring force of the torsion spring), and it automatically resets and presses when closed, making operation simple and efficient; 2. This utility model provides continuous clamping force through torsion springs, and with the matching structure of convex strips and grooves, the curtain is not easy to loosen during transportation vibration, the sealing effect is more stable, and the rubber gasket can play an anti-loosening role by elastically fitting the shaft, reducing the probability of shaft displacement caused by vibration.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Example 1: A bag-type storage box with multiple layers of parts storage space, such as Figures 1-9 As shown, the structure includes a base 1, a top panel box body 2, a cloth bag 6 installed inside the body 2, a curtain 7 installed above the outer surface of the body 2, a mounting base 9 bolted to the top of the base 1, and a rotating shaft 10 connected inside the mounting base 9 via a polytetrafluoroethylene bearing. A pressure plate 12 is installed on the outer wall of the rotating shaft 10, and protrusions 14 are provided on both sides of the back of the pressure plate 12. Torsion springs 11 are sleeved at both ends of the rotating shaft 10, with one end of the torsion spring 11 fixedly connected to the inner wall of the mounting base 9 and the other end of the torsion spring 11 fixedly connected to the pressure plate 12. The base 1 provides the load-bearing foundation for the overall structure and is used to install the body 2 of the body 2. The body 2 of the body 2 forms a storage cavity to accommodate multiple layers of cloth bags, providing overall protection and support.

[0029] See Figures 1-7 The top of the body 2 of the pallet box is covered with a top cover 4, and the top of the top cover 4 is provided with multiple positioning slots 5. The top cover 4 can cover the top of the body 2 of the pallet box to prevent external impurities from entering the interior of the pallet box through the top of the body 2 of the pallet box. The bottom of the base 1 is equipped with multiple support feet 3, and the number of support feet 3 is the same as the number of positioning slots 5. The support feet 3 are adapted to the positioning slots 5. Through the adaptation of the support feet 3 and the positioning slots 5, the stable stacking of multiple pallet boxes can be achieved (such as multi-layer stacking during workshop storage and logistics transportation).

[0030] See Figures 1-9 The pressure plate 12 is U-shaped and made of POM material. The U-shaped structure can be adapted to the width of the curtain to ensure uniform pressing. POM material (polyoxymethylene) has high hardness, wear resistance and self-lubrication, which is suitable for the frequent rotation of the pressure plate 12. The pressure plate 12 is rotatably connected to the mounting base 9 through the rotating shaft 10. The torsion spring 11 is made of 65Mn spring steel material and the hardness is controlled between HRC42-48. The limitation of the material (65Mn spring steel) and hardness (HRC42-48) of the torsion spring 11 ensures that the torsion spring 11 has sufficient elasticity (to achieve reliable pressing) and is not easy to break (to adapt to high frequency opening and closing).

[0031] Example 2: Based on the above embodiment one, Hassan will set up the following structure to facilitate viewing the internal situation of the enclosed box.

[0032] Specifically, a transparent window 16 is installed on the outer surface of the curtain 7, and the transparent window 16 is made of PVC transparent film. Visual viewing is achieved through the PVC transparent window 16, and the internal situation of the enclosure box can be viewed without opening or closing the curtain 7.

[0033] Example 3: Based on the above embodiment 1, in order to reduce the probability of vibration causing the rotating shaft 10 to shift, the following structure will be set.

[0034] Specifically, both sides of the curtain 7 are wrapped with rubber strips 8, and the outer surface of the rubber strips 8 has grooves 13. The rubber strips 8 enhance the edge strength of the curtain 7 and prevent tearing caused by frequent opening and closing. The protruding strips 14 are inserted into the interior of the grooves 13. The protruding strips 14 and the grooves 13 are matched. Through the "interlocking" fit of the protruding strips 14 into the grooves 13, the fixing effect of the pressure plate 12 on the curtain 7 can be improved, achieving precise positioning. Even if there is vibration during transportation, it is not easy to loosen. Washers 15 are installed on both sides of the interior of the mounting base 9. The washers 15 are made of rubber material. The outer wall of the rotating shaft 10 fits against the inner wall of the washers 15. The rubber washers 15 can play an anti-loosening role by elastically fitting the rotating shaft 10, reducing the probability of the rotating shaft 10 shifting due to vibration.

[0035] The working principle of this utility model is as follows: First, the staff classifies and places the parts into the multi-layer cloth bag 6. After closing the curtain 7, the elastic potential energy of the torsion spring 11 drives the pressure plate 12 to rotate around the rotating shaft 10. The protrusion 14 on the back of the pressure plate 12 is embedded in the groove 13 of the rubber strips 8 on both sides of the curtain 7, so as to reliably press and fix the curtain 7. When it is necessary to take out or put out the parts, the pressure plate 12 is manually rotated to overcome the elastic force of the torsion spring 11, so that the protrusion 14 is disengaged from the groove 13, and then the curtain 7 can be opened. After taking out or putting out the parts, the pressure plate 12 is released, and the torsion spring 11 is reset, which drives the pressure plate 12 to press the curtain 7 again. Staff can directly view the types and inventory of internal parts through the PVC transparent window 16 on the curtain 7 without opening the curtain 7, thus improving management efficiency. When multiple collapsible boxes need to be stacked, the support feet 3 of the lower collapsible box are inserted into the positioning grooves 5 of the top cover of the upper collapsible box to achieve precise positioning and ensure the stability after stacking.
