Description

Technical Field

[0001] This invention relates to the field of storage structure technology, and more particularly to an aluminum layer storage cabinet with adjustable internal space. Background Technology

[0002] Aluminum-clad storage cabinets refer to cabinets with aluminum foil coverings or aluminum frames. Aluminum forms a dense oxide film in the air, preventing rust and greatly increasing durability. Due to their lightweight, moisture-proof, corrosion-resistant, and modern appearance, aluminum-clad storage cabinets are widely used for storage in homes, laboratories, workshops, and humid environments.

[0003] To accommodate the storage requirements of different items, the common adjustment method is to install pull-out shelves inside the aluminum storage cabinet, or to make holes in the cabinet and use latches to change the position of the shelves.

[0004] However, in actual long-term use, the regulating structure used for adjustment is at risk of corrosion. Most of the key parts of the regulating structure are made of electroplated carbon steel or ordinary carbon steel. Frequent movement of the partition in a humid environment causes wear and scratches, which leads to oxidation and corrosion of the internal iron-based material, making the regulating structure stuck and difficult to disassemble and assemble.

[0005] Furthermore, even with stainless steel or aluminum alloy adjusting parts, repeated sliding, insertion, and removal can cause wear due to lack of lubrication. Over time, this can lead to loosening of the fit or friction noise during adjustments. When users add lubricant themselves, they can easily contaminate the cabinet's inner walls and stored items. Since the adjusting mechanism is typically flush with the cabinet body, lubricant may not penetrate to the contact area. Summary of the Invention

[0006] In response to the problems mentioned above, the present invention provides an aluminum layer storage cabinet with adjustable internal space.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problem is as follows: an aluminum layer storage cabinet with adjustable internal space, including a cabinet body and a partition disposed inside the cabinet body, wherein an adjustment component is provided between the partition and the longitudinal side surface of the cabinet body, and the adjustment component includes: The slide rail is installed on the inner wall of the cabinet body, and its inner side has a set of locking blocks. The sliding component is fixed to the partition on the outside and engaged with the slide rail on the inside, and can slide horizontally along the slide rail. The locking component is slidably mounted on the sliding component. The locking component has a rotating tube extending into the sliding component. There are at least two horizontally arranged rotating tubes. The two rotating tubes contact the inner walls on both sides of the slide rail respectively. When the sliding component slides horizontally, the two rotating tubes can be adjusted to lock between the corresponding two sets of locking blocks. The lubricating component is installed inside the sliding component and is used to lubricate the inside of the rotating tube and the slide rail. The rotating tube is used to seal the lubricating oil output position of the lubricating component. The locking component has an adjustable gap between its lower end and the sliding component, so that the rotating tube and the lubricating oil output position of the lubricating component have an adjustable gap.

[0008] A further preferred embodiment of the present invention is: the slide rail is U-shaped when viewed from above, and is fixed to the inner wall of the cabinet body, with the slide rail opening facing outward horizontally; The card block is rectangular, and the space between the card block and the adjacent card block is used to support the rotating tube.

[0009] A further preferred embodiment of the present invention is: the slider includes: The first buckle plate is fixed to the partition plate on the outside and fastened to the slide rail on the inside. The first buckle plate can be moved and adjusted horizontally along the slide rail. The second snap plate is L-shaped and is integrally set with the first snap plate. The second snap plate has a through-hole mounting cavity for installing the fastener. The end of the first snap plate and the second snap plate is integrally set with an extended baffle, so that the outer side of the second snap plate forms an installation channel, which is a slide for the fastener.

[0010] A further preferred embodiment of the present invention is: the card component includes: The inner side of the card plate is embedded into the mounting cavity, the adjustment gap is located between the lower inner wall of the mounting cavity and the card plate, and the outer side of the card plate is slidably set in the mounting channel. There are at least two horizontal shafts, which are fixed to the inward side of the clamping plate, and the rotating tube is sleeved on the corresponding shaft; The outer fixing piece is set on the outside of the clamping plate and is used to limit the clamping plate. The outer fixing piece is fixed to the buckle plate.

[0011] A further preferred embodiment of the present invention is: the lubricating element includes: The injection chamber is fixed inside the buckle plate and is used to hold lubricating liquid. The discharge flat tube is integrally set at the lower end of the injection chamber and passes downward between the two rotating tubes, allowing the lubricating fluid to move downward; The protruding end has at least two outlets for lubricating liquid seepage at its oblique lower part, which are integrally set on both sides of the discharge flat pipe. When the baffle is fixed, the protruding end outlet is squeezed against the corresponding rotating pipe. When the baffle is adjusted, there is a gap between the protruding end outlet and the corresponding rotating pipe.

[0012] A further preferred embodiment of the present invention is that the lower oblique end face of the protruding end is arc-shaped, for fitting with the rotating tube.

[0013] A further preferred embodiment of the present invention is: an auxiliary structure is provided between the card plate and the second buckle plate, the auxiliary structure including: Mounting bracket one and mounting bracket two are integrated with the card plate, and mounting bracket two is integrated with the buckle plate two. The two are in a symmetrical C-shaped structure. The spring is in a stretched state, and its two ends are fixed with end plates respectively locked in mounting bracket one and mounting bracket two. These end plates are used to pull the locking parts downward so that the adjustment gap disappears.

[0014] A further preferred embodiment of the present invention is to adjust the gap width to 0.08 mm to 0.2 mm to control the downward oil seepage effect.

[0015] A further preferred embodiment of the present invention is: the card plate is provided with inner and outer double layers, one side of the outer layer is attached to the outer wall of the second buckle plate, and the other side is attached to the extended edge.

[0016] Compared with the prior art, the advantages of the present invention are as follows: 1. The baffle is adjustable. By setting up a lubricating component and a movable locking component, when the baffle is adjusted and moved, the rotating pipe is separated from the outlet of the protruding end, and the lubricating oil automatically seeps out and is applied to the rotating pipe to achieve lubrication, effectively reducing friction, wear and jamming. When the partition is fixed to bear the load, the rotating pipe is squeezed by gravity to seal the leakage outlet, preventing the lubricating oil from continuously leaking out, preventing excessive lubrication from contaminating the items, and achieving the saving of lubricating oil and long-term use.

[0017] 2. The rotating tube and the inner wall of the slide rail are in rolling contact, and with automatic lubrication, the resistance when the partition moves is minimal, and the partition position will not be offset. The locking block and the rotating tube provide gear positioning. After adjustment, the partition can be automatically locked. The structure is stable and reliable, and adjustment does not require tools.

[0018] 3. The lubricating oil only seeps out as needed during adjustment and automatically seals itself when stationary. The oil is consumed very slowly and does not need to be added frequently, thus avoiding premature failure of the adjustment structure due to lack of lubrication. Attached Figure Description

[0022] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes an aluminum-layer storage cabinet with adjustable internal space. Please refer to [link / reference]. Figures 1-11Specifically, the components for adjusting the position of partition 2 are at risk of corrosion, especially in areas requiring frequent movement. Wear and scratches can occur, causing the adjustment mechanism to become stuck and difficult to disassemble. Even stainless steel or aluminum alloy adjustment components can experience wear due to lack of lubrication, leading to loosening of the fit or friction noise during adjustment after prolonged use, increasing the difficulty of adjustment. Therefore, an aluminum-layered storage cabinet with adjustable internal space is proposed, including a cabinet body 1 and partitions 2 installed within the cabinet body 1. An adjustment component 3 is located between the partition 2 and the longitudinal side surface of the cabinet body 1. The adjustment component 3 includes: The slide rail 31 is installed on the inner wall of the cabinet body 1, and has a series of locking blocks 311 arranged on its inner side; The sliding member 32 is fixed to the partition plate 2 on the outside and engaged with the slide rail 31 on the inside, and can slide horizontally along the slide rail 31; The locking component 34 is slidably mounted on the sliding component 32. The locking component 34 has a rotating tube 343 extending into the sliding component 32. The rotating tube 343 has at least two horizontally arranged tubes. The two rotating tubes 343 contact the inner walls on both sides of the slide rail 31 respectively. When the sliding component 32 slides horizontally, the two rotating tubes 343 can be adjusted to be locked between the corresponding two sets of locking blocks 311. The lubricating component 33 is installed inside the sliding component 32 and is used to lubricate the inner side of the rotating pipe 343 and the slide rail 31. The rotating pipe 343 is used to close the lubricating oil output position of the lubricating component 33. The locking component 34 has an adjustable gap 36 between its lower end and the sliding component 32, so that the rotating pipe 343 and the lubricating component 33 have an adjustable gap.

[0025] Specifically, the slide rail 31 serves as a guide structure to guide the movement trajectory of the locking member 34. The sliding member 32 forms a shell structure, which can be made of aluminum alloy, and is fastened to the outside of the slide rail 31, allowing it to move along the extension direction of the slide rail 31. It should be noted that there can be a gap between the sliding member 32 and the slide rail 31 to avoid jamming during sliding. The locking member 34 is the main structure of this application. Its two internal rotating tubes 343 are clamped to the inner walls on both sides of the slide rail 31 and can slide along the extension direction of the slide rail 31, keeping the partition 2 in a horizontal state. When the rotating tubes 343 are locked between the two sets of locking blocks 311, they play a supporting role, supporting the partition 2. It should be noted that if the items placed on the partition 2 are relatively heavy, multiple sets of rotating tubes 343 can be used for support. The lubricating component 33 is a structure that holds lubricating oil. A certain amount of lubricating oil is added inside. When the locking component 34 is in a movable state, the lubricating oil can seep downwards. When the locking component 34 is in a fixed state, the lubricating oil seepage point is sealed.

[0026] like Figure 4 The diagram shows a partial structural schematic of the slide rail 31. The slide rail 31 is U-shaped when viewed from above and is fixed to the inner wall of the cabinet body 1. The opening of the slide rail 31 is horizontal and outward. The card block 311 is rectangular, and the space between the card block 311 and the adjacent card blocks 311 is used to support the rotating tube 343.

[0027] Specifically, the U-shaped structure of the slide rail 31 prevents the guide portion from contacting the items inside the cabinet body 1, thus preventing lubricant from contacting the items. It also prevents items from adhering to the guide portion of the slide rail 31 and thus securing the locking member 34. The distance between the locking block 311 and the adjacent locking block 311 is greater than the width of the locking position of the rotating tube 343, making it easy for the rotating tube 343 to be inserted between the locking block 311 and the adjacent locking block 311.

[0028] like Figures 5-6 As shown, the slider 32 includes: The outer side of the snap plate 321 is fixed to the partition plate 2, and the inner side is fastened to the slide rail 31. The snap plate 321 can be moved and adjusted horizontally along the slide rail 31. The second snap plate 322 is L-shaped and is integrally set with the first snap plate 321. The second snap plate 322 has a through mounting cavity 325 for mounting the fastener 34. The end of the first snap plate 321 and the second snap plate 322 integrally has an extended baffle 323, so that the outer side of the second snap plate 322 forms a mounting channel 324, which is a slide for the fastener 34.

[0029] Specifically, snap-on plate 321 and snap-on plate 322 are integrated and form a C-shaped structure facing inward, which partially covers the slide rail 31. The width is greater than the width of the slide rail 31, allowing the operator to move back and forth from the opening of the cabinet body 1. The installation channel 324 and the extended guard 323 formed are mainly used to limit the plate 341 so that it can only slide in the up and down direction.

[0030] like Figures 5-6 As shown, the card component 34 includes: The inner side of the card plate 341 is embedded in the mounting cavity 325. The adjustment gap 36 is located between the lower inner wall of the mounting cavity 325 and the card plate 341. The outer side of the card plate 341 is slidably disposed in the mounting channel 324. At least two horizontal shafts 342 are provided and fixed to the inward side of the clamping plate 341. The rotating tube 343 is sleeved on the corresponding shaft 342. The outer fixing piece 344 is disposed on the outside of the clamping plate 341 and is used to limit the clamping plate 341. The outer fixing piece 344 is fixed to the buckle plate 321.

[0031] Specifically, the card plate 341 is configured with inner and outer double layers. One side of the outer layer is attached to the outer wall of the second buckle plate 322, and the other side is attached to the extension edge 323. The inner layer is embedded in the mounting cavity 325. The card plate 341 can slide up and down through the set adjustment gap 36. The shaft 342 and its outer sleeve rotating tube 343 are used to insert between the two card blocks 311. It should be noted that when the rotating tube 343 is inserted between the two card blocks 311, due to the existence of the adjustment gap 36, the card plate 341 can slide up and down along the sliding member 32 by a small distance. Therefore, when adjusting the partition 2, the card plate 341 moves to the lower end under the action of the auxiliary structure 35. When the partition 2 is fixed, the position of the card plate 341 is fixed, the sliding member 32 moves downward under the action of gravity, and the corresponding card plate 341 moves to the upper end.

[0032] For details, please refer to the above. Figures 7-11 The reference diagram is shown.

[0033] like Figures 5-6 As shown, the lubricant 33 includes: The injection chamber 331 is fixed inside the buckle plate 321 and is used to hold lubricating liquid. The discharge flat tube 332 is integrally set at the lower end of the injection chamber 331 and passes downward between the two rotating tubes 343, so that the lubricating liquid can move downward. The protruding end 333 has at least two outlets for lubricating liquid seepage at its oblique lower part, which are integrally set on both sides of the discharge flat pipe 332. When the partition plate 2 is fixed, the outlet of the protruding end 333 is squeezed against the corresponding rotating pipe 343. When the partition plate 2 is adjusted, there is a gap between the outlet of the protruding end 333 and the corresponding rotating pipe 343.

[0034] Specifically, the aforementioned lubricating component 33 is mainly used to load lubricating oil and cooperates with the rotating pipe 343. The lubricating liquid seeps out at the protruding end 333 at an angle. The width can also be 0.08mm to 0.2mm, allowing the lubricating oil to seep downwards. When the rotating pipe 343 is closed, it achieves a sealing effect.

[0035] Specifically, the lower sloping end face of the protruding end 333 is arc-shaped, which is used to fit with the rotating tube 343. The larger fitting surface can prevent lubricating oil from seeping downwards when lubrication is not required.

[0036] like Figure 6 As shown, an auxiliary structure 35 is provided between the card plate 341 and the buckle plate 322. The auxiliary structure 35 includes: Mounting bracket 1 351 and mounting bracket 2 352 are integrated with the card plate 341 and the mounting bracket 2 352 is integrated with the buckle plate 2 322. The two are in a symmetrical C-shaped structure. The retraction spring 353 is in a stretched state, and both ends of it are fixed with end plates 354 respectively locked in the mounting bracket 351 and the mounting bracket 352. These end plates are used to pull the locking member 34 downward so that the adjustment gap 36 disappears.

[0037] When the partition 2 moves upward without the auxiliary structure 35, the clamping plate 341 provides resistance and the adjustment gap 36 disappears. However, when the partition 2 moves downward, the adjustment gap 36 returns to its original state. Lubrication is only possible when the partition 2 moves upward.

[0038] The width of the adjustable gap 36 is 0.08mm to 0.2mm, which is used to control the downward oil seepage effect. The width of the adjustable gap 36 is the range of movement of the rotating pipe 343, ensuring that the lubricating oil can move downward to the rotating pipe 343 without causing excessive lubricating oil.

[0039] Working principle: Adjusting partition 2: Pull partition 2 towards the opening of cabinet body 1. Partition 2 will cause snap-on plates 321 and 322 to move outwards. The rotating tube 343 will disengage from between the two locking blocks 311, and the sliding member 32 can move along the extension direction of the slide rail 31 to adjust the position of partition 2. It should be noted that the number of locking blocks 311 can determine the adjustment level of partition 2, allowing for more precise height adjustment.

[0040] During the lubrication process of partition 2 adjustment: The rotating tube 343 disengages from between the two locking blocks 311. Under the contraction action of the compression spring 353, the adjustment gap 36 disappears, and the inner layer of the locking plate 341 faces downward and fits against the lower inner wall of the mounting cavity 325. At this point, there is a gap between the protruding end 333 and the rotating tube 343. When partition 2 moves, the rotating tube 343 rolls along the inner wall of the slide rail 31, achieving lubrication of the rotating tube 343 and the inner wall of the slide rail 31, making the movement of partition 2 smoother. It should be noted that the slide rail 31 has a U-shaped structure, and the opening faces the opening side of the cabinet body 1. When lubricating inside, it will not contaminate the objects inside the cabinet body 1.

[0041] After the partition 2 is adjusted and reset: push the partition 2 towards the inside of the cabinet body 1, the rotating tube 343 is locked between the two locking blocks 311, and under the action of the gravity of the partition 2, the locking part 34 remains in place, the sliding part 32 sinks slightly, so that the adjustment gap 36 is restored, and the contraction spring 353 is stretched again.

[0042] After the partition 2 is reset, the lubrication structure is as follows: the rotating pipe 343 and the protruding end 333 are squeezed to block the lubricating oil seepage outlet, so as to prevent excessive lubricating oil from seeping out and affecting the items inside the cabinet body 1. It can also maintain long-term lubrication and reduce the frequency of adding lubricating liquid.
