Description

Technical Field

[0001] The invention relates to the technical field of transportation and storage, and in particular to a product transportation and storage device. Background Art

[0002] Product transportation and storage is an important part of industrial design, which is directly related to product quality assurance, cost control and the ultimate realization of user experience from the production end to the user end. From the user's perspective, the user's demand is not to own the product, but the function, value, feeling and experience brought by the product. To stand out in the market competition, companies must develop "touching" comprehensive solutions based on user needs and emotional experience.

[0003] The profit model of enterprises in the post-industrial society is changing. Research has found that more and more manufacturers are starting from the entire product life cycle, expanding their focus from simple products to product use, maintenance and upgrades, spare parts market, recycling and reproduction, etc.; by optimizing the transportation and storage design of products, cost optimization, quality assurance and environmental friendliness can be achieved throughout the product life cycle, thereby creating greater value for enterprises and users.

[0004] However, although the existing traditional devices can meet the basic transportation and storage needs of products to a certain extent, they often have many problems: First, the product is not adequately protected. Traditional devices cannot effectively cope with the influence of the external environment during transportation and storage, such as dust, moisture, and impact. Industrial products usually have sophisticated craftsmanship and special materials, and are very sensitive to environmental factors (such as temperature, humidity, and dust). If improper protection measures are taken, the product may be damaged during transportation and storage. In addition, when the temperature and humidity are abnormal, traditional devices lack effective warning methods and cannot detect and deal with environmental changes in a timely manner, which may lead to product performance degradation or even damage.

[0005] Second, it is difficult to fix and manage. In terms of product fixation, the limitations of traditional devices may cause shaking and collision during transportation, thereby increasing the risk of product damage. Traditional devices often lack convenient visual design and cannot intuitively view the status of the product. This design deficiency has brought many inconveniences to the inspection and management work of staff during transportation and storage, reducing efficiency.

[0006] In response to the above problems, the present invention document proposes a product transportation and storage device. Through the optimized design of the product transportation and storage device, it can not only effectively solve the many problems existing in the traditional device, but also improve the product quality assurance and logistics efficiency, further conform to the user-centered industrial design concept, and provide strong support for sustainable development.

A sliding guide groove 34 is designed on one side of the rotating column 33, and the sliding guide groove 34 is slidably matched with the guide rail 31, so that the rotating column 33 and the base block 32 can be lifted and lowered together. The top of the rotating column 33 is rotatably connected to a rotating bracket 44 (the rotating bracket 44 is L-shaped) through a rotating shaft, and a groove for making way for the rotating bracket 44 is arranged at the top of the top of the rotating column 33, and the bottom end of the rotating bracket 44 is fixedly connected to the top of the cleaning brush 45. In this way, when the cleaning brush 45 is rotated, it can be placed on the top of the transparent protective cover 5 (at this time, the rotating bracket 44 is placed in the groove at the top of the rotating column 33), and then the transparent protective cover 5 is driven to rotate, and the cleaning brush 45 can clean the top of the transparent protective cover 5. When the outer wall of the transparent protective cover 5 needs to be cleaned, the cleaning brush 45 only needs to be reset, and then the rotating column 33 is rotated to make the cleaning brush 45 face the transparent protective cover 5, and the transparent protective cover 5 is driven to rotate again, and the cleaning brush 45 can clean the outer wall of the transparent protective cover 5.

[0037] Reference Figure 2 , Figure 8 and Fig. 9 A support platform 46 is designed on the top of the base chassis 1 to support the base block 32. When the base block 32 and the rotating column 33 need to be stored, the base block 32 and the rotating column 33 will move down under the action of the guide rail 31 until the base block 32 rests on the support platform 46. In this way, the support platform 46 can prevent the rotating column 33 from being out of sliding fit with the guide rail 31.

[0038] Reference Figure 4 and Figure 7 On the inner wall of the transparent protective cover 5, a plurality of No. 2 magnets 30 are fixedly embedded. On the top of the carrier plate 4, a plurality of L-shaped rods 28 are fixed, and the ends of these L-shaped rods 28 that are away from each other are fixed with No. 1 magnets 29. A magnetic attraction is generated between the No. 1 magnet 29 and the No. 2 magnet 30, so when the carrier plate 4 rotates, the transparent protective cover 5 is driven to rotate together through the magnetic attraction of the No. 1 magnet 29 and the No. 2 magnet 30.

[0039] Reference Figure 4 and Figure 7In addition, a No. 1 gear 25 is designed on the outer wall of the fixed guide tube 20. A rotating motor 26 is fixed on the top of the No. 2 cylinder 19. A No. 2 gear 27 meshing with the No. 1 gear 25 is fixed on the output shaft of the rotating motor 26. In this way, the rotating motor 26 can drive the carrier plate 4 to rotate through the cooperation of the No. 2 gear 27 and the No. 1 gear 25. Furthermore, the carrier plate 4 drives the transparent protective cover 5 to rotate through the magnetic attraction between the No. 1 magnet 29 and the No. 2 magnet 30, so that the cleaning brush 45 can clean the side wall and the top of the transparent protective cover 5.

[0040] Reference Figure 8 A circular through hole 38 is designed on the side of the base block 32 away from the ring 3. A sliding rod 39 is slidably connected in the circular through hole 38. One end of the sliding rod 39 extends to one side of the base block 32 and is fixed with a connecting plate 41. A No. 2 tension spring 40 is fixed on the side where the connecting plate 41 and the base block 32 are close to each other. This No. 2 tension spring 40 is sleeved on the outer wall of the sliding rod 39 and is used to pull the connecting plate 41 to one side. A rubber clamping block 42 is fixed on the side of the connecting plate 41 close to the ring 3, which is used to limit the rotating column 33 and the cleaning brush 45.

[0041] Specifically, the rubber clamping block 42 will squeeze the rotating column 33 and the cleaning brush 45 under the tension of the second tension spring 40 to limit the two. When the cleaning brush 45 is cleaning, the rubber clamping block 42 will also limit the rotating column 33 to ensure the stability of the cleaning process.

[0042] Reference Figure 5 and Figure 6 A sealing cylinder 15 is sleeved on the outer wall of each driving screw 11, and these sealing cylinders 15 are fixedly connected to the bottom of the lifting sealing ring 10. A sealing gasket is fixed inside the sealing cylinder 15, and one end of the driving screw 11 seals through the sealing gasket. It is worth noting that the sealing gasket is located below the threaded section of the driving screw 11 to ensure that when the driving screw 11 rotates, the sealing between the lifting sealing ring 10 and the annular groove 7 will not be affected.

[0043] Specifically, when it is necessary to drive the lifting seal ring 10 to move downward, it can be achieved by rotating the transmission screw 11. At this time, due to the presence of the sealing cylinder 15 and the sealing gasket, the lifting seal ring 10 can fit tightly on the side wall of the annular groove 7, thereby squeezing the gas in the annular groove 7 into a No. 1 cylinder 18. A No. 1 piston 22 is arranged in the No. 1 cylinder 18. When the gas is squeezed into the No. 1 cylinder 18, the No. 1 piston 22 will move downward, thereby driving an adsorption mechanism to operate, which is used to further fix or process the product sample.

[0044] Reference Figure 4 In addition, in order to provide a secondary warning for abnormal temperature and humidity from below, a plurality of No. 2 warning light strips 47 are fixed to the inner wall of the placement ring 3. These No. 2 warning light strips 47 can emit dazzling light to achieve a more eye-catching warning light effect, provide guidance for the staff, and facilitate quick identification of storage devices with abnormal temperature and humidity, and then take effective measures to control the temperature and humidity.

[0045] The transparent protective cover 5 and the carrying plate 4 are both made of acrylic material, which has good transparency and can protect the product samples while allowing the staff to clearly inspect the products.

[0046] Through the above implementations, the device can achieve stable storage, inspection and cleaning of products, thereby improving the safety and storage effect of the products.

[0047] Example 2 refer to Fig.10 and Fig.11 , based on the improvement of Example 1: a guide rod 48 is fixed inside the base chassis 1, and a pad 49 is provided on the outer wall of the guide rod 48. This pad 49 can be used as a resting point for the staff. Support plates 50 are fixed on both sides of the bottom of the pad 49. When the pad 49 is pulled outward, the support plates 50 can be placed on the base chassis 1, thereby maintaining the stability of the pad 49. At the same time, support columns 51 are also fixed on the bottom of the pad 49. These support columns 51 work together with the support plates 50 to provide additional support for the pad 49.

[0048] In summary, the device not only protects, stores and views product samples through clever mechanism design, but also improves the warning effect through the second warning light strip 47 and the transparent protective cover 5 made of acrylic material. At the same time, the design of the guide rod 48, the pad 49, the support plate 50 and the support column 51 and other structures provides a more convenient inspection effect for the staff.

[0049] Example 3 refer to Fig.12 and Fig.13 , improved on the basis of Example 2: an annular groove 53 is provided on the top of the base chassis 1, and a protective cover 54 is mounted in the annular groove 53 to protect the support frame 2 and the transparent protective cover 5 to prevent the support frame 2 and the transparent protective cover 5 from being bumped during transportation.

[0050] A method for using a product transportation and storage device comprises the following steps: S1. Place the product on the carrier plate 4, insert the transparent protective cover 5 and the bottom ring 6 into the annular groove 7, the bottom ring 6 is placed on the top of the lifting sealing ring 10, and the top of the driving screw 11 just extends to the threaded hole at the bottom of the bottom ring 6. Through the cooperation of the bevel gear ring 13 and the multiple bevel gears 12, the driving motor 14 can simultaneously drive the multiple driving screws 11 to rotate, the driving screw 11 drives the bottom ring 6 and the transparent protective cover 5 to move downward, the bottom ring 6 pushes the lifting sealing ring 10 to move downward and compresses the spring 9, so that the transparent protective cover 5 and the bottom ring 6 can be installed on the placement ring 3; S2. When the lifting seal ring 10 moves downward, the air in the annular groove 7 is injected into the No. 1 cylinder 18 through the air pipeline 21, and the No. 1 piston 22 drives the No. 2 piston 24 to move downward under the pressure in the No. 1 cylinder 18. The No. 2 piston 24 can make the multiple suction discs 17 generate suction force on the product, adsorbing the product on the top of the carrying plate 4 to prevent the product from falling from the placement ring 3 and the carrying plate 4; S3, then pull the base block 32 and the rotating column 33 upward through the guide rail 31 until the latch rod 36 is inserted into the latch hole 35 under the tension of the No. 1 tension spring 37, position the base block 32, pull the connecting plate 41 outward, release the limit on the rotating column 33, rotate the rotating column 33, so that the No. 1 warning light strip 43 faces the transparent protective cover 5, and then drive the No. 2 gear 27 to rotate through the No. 1 gear 25. The No. 2 gear 27 drives the fixed guide tube 20, the cross tube 16 and the bearing plate 4 to rotate. When the temperature and humidity sensor 52 detects abnormal temperature and humidity, the No. 1 warning light strip 43 and the No. 2 warning light strip 47 are respectively started to provide a first-level warning and a second-level warning for the abnormal temperature and humidity, and the bearing plate 4 drives the product to rotate so that it can be fully inspected by the staff, wherein the temperature and humidity sensor 52, the No. 1 warning light strip 43 and the No. 2 warning light strip 47 are all connected to the controller; S4. When it is necessary to clean the top of the transparent protective cover 5, the connecting plate 41 is pulled outward to release the limit of the rotating column 33 and the cleaning brush 45, and the cleaning brush 45 is rotated to place the cleaning brush 45 on the top of the transparent protective cover 5, and then the supporting plate 4 is driven to rotate. The supporting plate 4 drives the transparent protective cover 5 to rotate through the magnetic attraction between the first magnet 29 and the second magnet 30, and the cleaning brush 45 can clean the top of the transparent protective cover 5; when it is necessary to clean the outer wall of the transparent protective cover 5 , reset the cleaning brush 45, then rotate the rotating column 33 to make the cleaning brush 45 face the transparent protective cover 5, and drive the transparent protective cover 5 to rotate again, and then the cleaning brush 45 can clean the outer wall of the transparent protective cover 5 to ensure the cleanliness of the outer wall of the transparent protective cover 5; when the base block 32 and the rotating column 33 are stored, the base block 32 and the rotating column 33 move downward under the action of the guide rail 31 until the base block 32 is placed on the support platform 46, and the support platform 46 prevents the rotating column 33 from being out of sliding fit with the guide rail 31; S5. When the staff is tired, the pad 49 is pulled outward, and the support plate 50 can be placed on the base chassis 1. The staff can then sit on the pad 49 to rest, giving the staff a more comfortable experience.

[0051] However, as is well known to those skilled in the art, the working principles and wiring methods of the No. 1 warning light strip 43, the No. 2 warning light strip 47, the rotating motor 26 and the driving motor 14 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.
