Description

Technical Field

[0001] This utility model relates to the field of food production storage technology, and in particular to a storage rack structure that can be quickly disassembled. Background Technology

[0002] In the field of aviation food production, various types of storage racks are widely used to meet the needs of material preparation and temporary storage in mass production, especially for providing storage space for ingredients such as meat. At the same time, considering that meat and other ingredients may produce thawing liquid during storage, the storage racks are usually designed with condensation trays to collect this liquid, preventing it from contaminating the production environment and ensuring the cleanliness of the production area. However, the existing racks used in aviation food production have significant shortcomings in their structural design regarding the installation methods of the storage rods and water collection trays, resulting in poor ease of disassembly. Regarding the storage rods, most use fixed connections, such as welding or rigid connections to the rack body via complex structures, making them difficult to remove. This leads to food residue and grease accumulating in the gaps and joints between the storage rods and the rack body during later cleaning and maintenance, making thorough cleaning difficult. Over time, this can potentially breed bacteria, failing to meet the extremely high hygiene requirements of aviation food production. For drip trays, their connection to the frame is often fixed or requires tools to disassemble. After a period of use, drip trays accumulate a significant amount of thawed water and impurities, requiring regular cleaning. However, due to the difficulty of disassembly, workers often need to spend considerable time and effort, increasing labor intensity and potentially leading to bacterial growth inside the drip tray due to untimely or incomplete cleaning, thus affecting food production safety. Furthermore, when the storage rods need to be replaced due to wear, deformation, or other issues caused by long-term use, their structure makes disassembly difficult, requiring workers to perform complex operations and potentially necessitating a certain degree of disassembly of the frame. This not only prolongs the replacement time and affects production progress but may also cause unnecessary damage to the frame. Therefore, the existing storage racks used in aviation food production have defects in the detachability of the storage rods and water collection trays, which makes cleaning and maintenance difficult and parts replacement inconvenient. They cannot efficiently meet the strict requirements of aviation food production and need to be further improved. Utility Model Content

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] See Figures 1-7 A quick-disassembly shelving structure includes a rear fixing frame 10, with front fixing rods 20 spaced apart on the left and right sides of the front fixing frame 10. A plurality of shelf rods 30 are arranged longitudinally between the rear fixing frame 10 and the front fixing rods 20, and the shelf rods 30 are fixedly connected to the rear fixing frame 10 and the front fixing rods 20. A plurality of storage rods 40 are arranged in the front-back direction between the left and right shelf rods 30, with a water collection tray 50 below each storage rod 40. A plurality of insertion holes 320 are arranged along the front-back direction on the shelf rods 30. The wall surface of the rod 30 facing another shelf rod 30 is provided with a slot 330 with a front opening. The shelf rod 30 is provided with an installation space 340 that communicates with the insertion hole 320 and the slot 330. The storage rod 40 is provided with an insertion post 410 that is inserted into the insertion hole 320 and extends into the insertion hole 320. The left and right sides of the water collection tray 50 are provided with insertion strips 510 that are inserted into the slot 330. The installation space 340 is provided with a locking module 60 for locking the insertion post 410 and the insertion strip 510.

[0015] The operating principle of this quick-disassembly shelving structure is based on the interlocking and locking mechanisms between its components, as detailed below: During installation, the shelf rods 30 are fixedly connected to the rear fixing frame 10 and the front fixing rod 20 via existing detachable connection structures such as bolts, forming the basic frame of the shelf and providing stable support for the installation of subsequent components. For the shelf rods 40, the plug-in posts 410 at both ends need to be aligned with the corresponding plug-in holes 320 on the left and right shelf rods 30, and the plug-in posts 410 are inserted into the plug-in holes 320 until they extend into the installation space 340 of the shelf rods 30. The installation of the water collection tray 50 is achieved by aligning the plug-in strips 510 on its left and right sides with the slots 330 on the shelf rods 30. Since the slots 330 are open at the front, the plug-in strips 510 can be directly pushed into the slots 330 from the front, so that the plug-in strips 510 also extend into the installation space 340. Once the storage rod 40 and the water collection tray 50 are in place, the locking module 60 within the installation space 340 will lock the insertion post 410 and the insertion strip 510. At this time, the locking module 60 closely engages with the insertion post 410 and the insertion strip 510, restricting their movement within the insertion hole 320 and the slot 330. This ensures that the storage rod 40 can stably support the food, and that the water collection tray 50 can reliably collect the thawing water, guaranteeing the structural stability of the storage rack during use. When it is necessary to disassemble the storage rod 40 or the water collection tray 50 for cleaning or replacement, simply operate the locking module 60 to release the locking of the plug post 410 and the plug strip 510. Then, for the storage rod 40, it can be pulled outwards to disengage the plug post 410 from the plug hole 320; for the water collection tray 50, it can be pulled out from the front along the slot 330 to disengage the plug strip 510 from the slot 330, achieving quick disassembly.

[0016] See Figure 4 and Figure 7 The locking module 60 includes a locking plate 610 movably disposed within the mounting space 340, the locking plate 610 extending at least partially to the outside of the mounting space 340; the locking plate 610 has a through-hole 611; a plug-in post 410 is inserted into the through-hole 611; the plug-in post 410 has a locking groove 420; the plug-in strip 510 is a rack, and the locking plate 610 has locking teeth 612 on the side facing the plug-in strip 510; the locking plate 610 moves relative to the mounting space 340 between a locked position and an unlocked position; when the locking plate 610 is in the locked position; the locking plate 610 is at least partially inserted into the locking groove 420 and the locking teeth 612 engage with the plug-in strip 510; when the locking plate 610 is in the unlocked position; the locking plate 610 is separated from the locking groove 420 and the locking teeth 612 are separated from the plug-in strip 510.

[0017] The locking module 60 works based on the positional movement of the locking plate 610 to lock and unlock the storage rod 40 and the water collection tray 50, as detailed below: The locking plate 610 is movable within the installation space 340 and extends at least partially to the outside of the installation space 340, facilitating position switching operations by the operator. When the storage rod 40 and the water collection tray 50 are installed in place, the insertion post 410 of the storage rod 40 will be inserted into the through-hole 611 of the locking plate 610, while the rack-shaped insertion strip 510 of the water collection tray 50 will be positioned corresponding to the locking teeth 612 on the locking plate 610. When locking is required, the operator moves the portion extending to the outside of the installation space 340 to switch the locking plate 610 to the locked position. At this time, at least a portion of the locking plate 610 will insert into the locking groove 420 on the plug post 410, limiting the plug post 410 and preventing it from moving within the plug hole 320; at the same time, the locking teeth 612 on the locking plate 610 will mesh with the rack-shaped plug bar 510 of the water collection tray 50, restricting the movement of the plug bar 510 within the slot 330, thereby achieving a secure lock on the storage rod 40 and the water collection tray 50. When unlocking is required for disassembly, the operator moves the locking plate 610 again to the unlocked position. At this time, the locking plate 610 retracts from the locking groove 420 of the plug post 410 and separates from the locking groove 420; simultaneously, the locking teeth 612 disengage from the rack-shaped plug strip 510, releasing the restriction on the plug post 410 and the plug strip 510. In this way, the plug post 410 of the shelf rod 40 can be pulled out from the plug hole 320, and the plug strip 510 of the water collection tray 50 can also be pulled out from the slot 330, realizing the quick disassembly of the shelf rod 40 and the water collection tray 50. By simply moving the locking plate 610 between the locked and unlocked positions, the locking module 60 can efficiently lock and unlock the storage rod 40 and the water collection tray 50, making the operation convenient and the locking reliable.

[0018] In this utility model, the installation space 340 and the slot 330 are arranged on the left and right sides.

[0019] See Figure 4 , Figure 5 and Figure 7 The outer side of the installation space 340 is provided with a limiting plate 620 that is fixedly connected to the locking plate 610; the shelf rod 30 is provided with a guide post 630 extending along the moving direction of the locking plate 610; the limiting plate 620 is provided with a guide hole 621 corresponding to the guide post 630; the guide post 630 is movably inserted into the guide hole 621. A fixing member 640 is provided at the end of the guide post 630 away from the shelf rod 30, and a limiting plate 620 is provided between the fixing member 640 and the shelf rod 30; a spring 650 is sleeved on the guide post 630 between the fixing member 640 and the limiting plate 620. One end of the spring 650 abuts against the limiting plate 620 and the other end abuts against the fixing member 640; the spring 650 is used to push the locking plate 610 from the unlocked position to the locked position.

[0020] The guide post 630 on the shelf rod 30 extends along the moving direction of the locking plate 610 and is movably inserted into the guide hole 621 of the limiting plate 620, while the limiting plate 620 is fixedly connected to the locking plate 610. This guiding and mating structure provides precise guidance for the movement of the locking plate 610, ensuring that the locking plate 610 can move stably in the preset direction when switching between the locked and unlocked positions, avoiding deviation, jamming, etc., and ensuring the smoothness of the locking and unlocking actions. The fixing member 640 is located at the end of the guide post 630 away from the shelf rod 30, and the limiting plate 620 is located between the fixing member 640 and the shelf rod 30. A spring 650 is sleeved on the guide post 630 between the fixing member 640 and the limiting plate 620. When the operator pushes the limiting plate 620 to move the locking plate 610 to the unlocked position, the limiting plate 620 compresses the spring 650, causing the spring 650 to store elastic potential energy. At this time, the locking plate 610 switches from the locked position to the unlocked position, releasing the restriction on the insertion post 410 and the insertion strip 510. When the operator releases the limiting plate 620, the spring 650 releases its stored elastic potential energy. One end of the spring exerts a pushing force on the limiting plate 620, while the other end abuts against the fixing member 640, creating a reaction force. This pushes the limiting plate 620, causing the locking plate 610 to reset along the guide post 630, automatically moving the locking plate 610 from the unlocked position to the locked position. During this process, the locking plate 610 re-inserts into the locking groove 420 of the insertion post 410, and the locking teeth 612 re-engage with the rack-shaped insertion strip 510, achieving automatic locking without additional manual operation. This improves the convenience and reliability of locking and effectively prevents the storage rod 40 or the water collection tray 50 from becoming loose due to forgetting to lock.

[0021] In this invention, the limiting plate 620 is connected to a handle 660. The handle 660 connected to the limiting plate 620 provides a convenient point of force for the operator to operate the locking module. When unlocking is required, the operator can easily move the limiting plate 620 and the locking plate 610 by pulling the handle 660, compressing the spring 650 and quickly switching the locking plate 610 from the locked position to the unlocked position. After the operation is completed, the handle 660 can be released without direct contact with the limiting plate 620, simplifying the operation process and improving the convenience and comfort of operation. Especially when frequently disassembling or installing the loading rod or water collection tray, it can effectively reduce operator fatigue. In this utility model, the fixing member 640 is a nut, and the fixing member 640 is threadedly connected to the guide post 630.

[0022] In this invention, the upper surface of the shelf rod 30 is provided with a downwardly recessed positioning groove 310, and the storage rod 40 is at least partially inserted into the positioning groove 310.

[0023] In this invention, the insertion hole 320 is disposed within the positioning groove 310. The positioning groove 310 on the upper surface of the shelf rod 30 can accurately position the shelf rod 40. When the shelf rod 40 is installed, at least part of it is inserted into the positioning groove 310, which can limit the horizontal displacement of the shelf rod 40. Together with the insertion post and locking module, it further improves the stability of the shelf rod after installation and prevents it from shifting due to force during use.
