Abstract
Description
Technical Field
[0001] This utility model relates to the field of stackable frames, specifically to a stackable frame that can extend outwards at height. Background Technology
[0002] A stackable rack that can extend to a high altitude is a specially designed stacking rack that combines the advantages of traditional stackable racks, such as uniform specifications, fixed capacity, and clear visibility of stored goods, with the ability to extend to a high altitude to adapt to specific warehousing and logistics needs. To achieve this extension, such stackable racks may be equipped with adjustable or telescopic components, allowing the rack to extend upwards while maintaining stability to accommodate storage needs at different heights.
[0003] The existing technology has the following problems:
[0004] The existing equipment cannot be height-adjusted during use. This lack of height adjustment means that the stackable racks cannot maximize the use of vertical space according to actual needs. In low-ceilinged spaces, it may not be able to fully utilize the upper space for storage, resulting in limited storage capacity. The lack of height adjustment reduces the applicability of the stackable racks in different scenarios, making it difficult to quickly access goods. Furthermore, the existing equipment cannot be extended to higher levels. Stackable racks that cannot be extended cannot fully utilize warehouse or workshop space, especially when it is necessary to expand the storage area. This may lead to insufficient storage space and failure to meet storage needs. Stackable racks that cannot be extended may not be able to work perfectly with forklifts or other handling equipment, increasing safety risks during operation. Utility Model Content

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:
[0024] like Figure 1-2As shown, this utility model provides a high-altitude extendable support frame, including a base 1. Multiple fixed columns 2 are fixedly connected to the upper side of the base 1. Fixed blocks 3 are fixedly connected to the upper end of the outer wall of the fixed columns 2. Connecting plates 23 are fixedly connected to the outer wall of the fixed columns 2. A lifting column 6 is slidably connected through the upper side of the fixed columns 2. A top plate 4 is fixedly connected to the upper end of the lifting column 6. A knob 5 is rotatably connected to the front side of the top plate 4. A fixed plate 7 is fixedly connected to the side of the lifting column 6 near the fixed blocks 3. Several slots 24 are opened on the side of the fixed plate 7 near the fixed blocks 3. A handle 8 is fixedly connected to the side of the fixed blocks 3 away from the lifting column 6. During the use of the device, the height of the device can be adjusted according to the size of the goods.
[0025] like Figure 2-5 As shown, this utility model provides a technical solution: Preferably, the fixing column 2 has two grooves 10 on the side near the fixing block 3. A limiting rod 11 is fixedly connected to the upper side of the inner wall of the groove 10. A first spring 12 is sleeved on the outer wall of the limiting rod 11. A locking plate 9 is slidably connected to the outer wall of the limiting rod 11. Two locking slots 13 are opened on both the upper and lower sides of the fixing block 3. The outer wall of the locking plate 9 is movably connected to the locking slot 13. One end of the first spring 12 is fixedly connected to the locking plate 9, and the other end of the first spring 12 is fixedly connected to the fixing column 2. A connecting block 14 is fixedly connected to the side of the fixing block 3 near the lifting column 6. A baffle 15 is fixedly connected to the side of the connecting block 14 near the fixing plate 7. Multiple locking blocks 16 are fixedly connected to the side of the baffle 15 away from the fixing block 3. The outer wall of the locking block 16 is movably connected to the slot 24. The outer wall of the connecting block 14 is slidably connected to the fixing column 2. Two connecting rods 25 are fixedly connected to the lower side of the inner wall of the fixing column 2. A second spring 26 is sleeved on the outer wall of the connecting rod 25. One end of the second spring 26 is fixedly connected to the fixed column 2, and the other end of the second spring 26 is fixedly connected to the lifting column 6. During the adjustment process, the locking plates 9 on both sides of the fixed block 3 can be pulled first. When the locking plates 9 are disengaged from the slot 13, the fixed block 3 can be pulled by the handle 8. When the fixed block 3 moves, it can drive the connecting block 14 to move. The movement of the connecting block 14 can drive the baffle 15 to move. The movement of the baffle 15 can drive the locking block 16 to move. When the locking block 16 is disengaged from the slot 24, the fixed plate 7 can be raised and lowered, thus driving the lifting column 6 to rise and fall. After the height adjustment is completed, the locking block 16 can be brought close to the inside of the slot 24 by the handle 8, and then the two locking plates 9 can be released. At this time, the first spring 12 can lock the locking plate 9 into the inside of the slot 13, limiting and fixing the fixed block 3, thereby limiting and fixing the locking block 16 and the slot 24. This design allows more goods to be stored in a limited ground space, improving the overall storage efficiency.
[0026] like Figure 6As shown, this utility model provides a technical solution: Preferably, a threaded rod 17 is fixedly connected to the rear side of the knob 5, and a movable block 22 is threadedly connected to the outer wall of the threaded rod 17. The lower side of the movable block 22 is slidably connected to the top plate 4, and a moving block 19 is fixedly connected to the upper side of the movable block 22. Two inclined grooves 20 are opened through the upper side of the moving block 19, and a limit post 21 is slidably connected to the inner surface of the inclined grooves 20. A telescopic plate 18 is fixedly connected to the lower end of the limit post 21, and the outer wall of the telescopic plate 18 is slidably connected to the top plate 4. The outer wall of the moving block 19 is also slidably connected to the top plate 4. When it is necessary to use the device... When the device is extended at a height, the knob 5 can be rotated first. The knob 5 can drive the threaded rod 17 to rotate. The rotation of the threaded rod 17 can drive the movable block 22 to move. The movement of the movable block 22 can drive the movable block 19 to move, thereby driving the inclined groove 20 to move. The cooperation between the inclined groove 20 and the limiting post 21 can drive the two telescopic plates 18 to move simultaneously to the middle or in opposite directions. When the two telescopic plates 18 move simultaneously in opposite directions, the device can be extended at a height, which can better utilize the vertical space of the warehouse, realize multi-layer storage, and thus increase the storage capacity.
[0027] The working principle of this high-altitude extendable frame will be explained in detail below.
[0028] like Figure 1-6 As shown, during the use of the device, the height of the device can be adjusted according to the size of the goods. During adjustment, the clamping plates 9 on both sides of the fixed block 3 can be pulled. When the clamping plates 9 disengage from the slot 13, the fixed block 3 can be pulled by the handle 8. The movement of the fixed block 3 can move the connecting block 14, which in turn moves the baffle 15. The movement of the baffle 15 can then move the clamping block 16. When the clamping block 16 disengages from the slot 24, the fixed plate 7 can be raised or lowered, thus raising or lowering the lifting column 6. After height adjustment, the clamping block 16 can be brought closer to the inside of the slot 24 by the handle 8, and then the two clamping plates 9 can be released. At this time, the first spring 12 can clamp the clamping plates 9 into the slot 13, thus adjusting the fixed block 3. The limiting and fixing mechanism secures the card block 16 and the slot 24, allowing for the storage of more goods within a limited floor space and improving overall storage efficiency. When the device needs to be extended at a height, the knob 5 can be rotated first. The knob 5 drives the threaded rod 17 to rotate, which in turn drives the movable block 22 to move. The movement of the movable block 22 drives the movable block 19 to move, which in turn drives the inclined groove 20 to move. The cooperation between the inclined groove 20 and the limiting post 21 allows the two telescopic plates 18 to move simultaneously towards the center or in opposite directions. When the two telescopic plates 18 move simultaneously in opposite directions, the device can be extended at a height, making better use of the warehouse's vertical space and enabling multi-layer storage, thereby increasing storage capacity.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
