Description

Technical Field

[0001] This utility model belongs to the field of shelving, and specifically relates to a telescopic shelving. Background Technology

[0002] Materials in factories are typically stored using stacking, piling, or shelving. Stacking and piling are suitable for bulk materials or materials of limited variety that can be accessed sequentially from top to bottom. When there are many types of materials, and for ease of access, factories use shelving to store them in an orderly manner. Shelving not only categorizes and organizes materials but also makes full use of the factory's vertical space. The tiered storage of shelving ensures that each tier operates independently, allowing people to easily access materials on any level.

[0003] However, when storing long strip materials, such as steel bars, steel bars, and pipes, the adjacent shelves may obstruct the end space when neatly arranged. Therefore, the materials can only be discharged to the side. However, in order to limit and organize the materials, baffles or posts are installed on the side of the shelves to prevent the materials from rolling down. This requires lifting the materials up and flipping them over the baffles or posts to remove them. When the materials are heavy, this is very time-consuming and laborious, and also poses a safety hazard. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem of existing shelving for strip materials where adjacent shelves obstruct the end space, requiring materials to be flipped over the side panels or columns to be moved out, which is time-consuming and laborious. This utility model provides a telescopic shelf that extends to the side when materials need to be stored or retrieved, making it convenient for materials to be stored and retrieved.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a telescopic rack, including a rack body, the rack body including a plurality of fixed frames, and movable supports that can extend and retract relative to the fixed frames are provided on one or both sides of the fixed frames; the fixed frame includes a guide sleeve, and the movable support includes a first telescopic arm slidably inserted in the guide sleeve and a second telescopic arm provided above the guide sleeve, the outer ends of the first telescopic arm and the second telescopic arm are fixed to each other, and two vertical stops are provided upward on the second telescopic arm, with a material storage space between the two vertical stops.

[0006] In this device, the movable support frame is extendable. When materials need to be stored, the movable support frame extends to the side of the main rack, so that the material storage position protrudes into the aisle relative to the adjacent rack, making it convenient for storage and retrieval. Especially for heavy materials such as steel pipes and rebars, they can be dragged from the end for loading and unloading, saving time and effort and avoiding the risks of lifting materials. At the same time, this rack also reduces the required aisle width for the rack support, allowing for more efficient use of factory space.

[0007] Preferably, a rack is provided in the middle of the lower wall of the outer end of the first telescopic arm, and a drive shaft is provided between the two ends of the main body of the shelf. The drive shaft passes through the lower part of the outer end of the guide sleeve, and a gear is provided at the corresponding position of the drive shaft and the rack. This device uses a drive shaft that runs through both ends of the shelf to drive the movable bracket to extend and retract. Movable brackets on the same side and at the same height are driven to extend and retract by the same drive shaft, maintaining synchronous extension and retraction.

[0008] Preferably, a rocker shaft is provided on the shelf body above or below the end of the drive shaft. The rocker shaft and the drive shaft are connected by a chain drive, and a detachable rocker arm is provided at the outer end of the rocker shaft. To make full use of the height space, the lowest shelf is close to the ground, while the materials on the highest shelf are generally designed at the maximum height that people can access and operate at. Therefore, the rocker shaft is set and centered in the height direction, so that the rocker arm can avoid being inoperable at the lowest and highest points close to the ground.

[0009] Preferably, the fixing frame includes a column, and one or more guide sleeves are fixedly installed on the end face of the column from top to bottom. Each layer of guide sleeves can be provided with one, or two can be provided at the same height at both ends of the column.

[0010] Preferably, each movable support is located at the same end of each guide sleeve, or each movable support is located at both ends of each guide sleeve. Movable supports are installed on one or both sides of the rack body.

[0011] Preferably, the upper wall of the guide sleeve has a limiting baffle that cooperates with the second telescopic arm.

[0012] Preferably, the lower outer end of the guide sleeve is equipped with support rollers that support both sides of the lower wall of the first telescopic arm. The use of support rollers reduces telescopic resistance. Preferably, the two vertical stops are an outer stop and an inner stop, respectively. The outer ends of the first and second telescopic arms are welded and fixed to the inner sidewalls of the outer stops, and the inner stop is fixed to the inner end of the upper wall of the second telescopic arm. The outer stop also serves as a connector between the first and second telescopic arms.

[0013] Preferably, a first roller is provided at the inner end of the first telescopic arm, with the upper surface of the first roller higher than the upper wall of the first telescopic arm and the lower surface of the first roller lower than the lower wall of the first telescopic arm. During the extension and retraction of the movable bracket, due to the lever effect, the first telescopic arm rolls in contact with the inner upper or lower wall of the guide sleeve.

[0014] Preferably, a second roller is provided on the lower inner wall of the second telescopic arm.

[0015] The shelf of this utility model is controlled by telescopic extension. It is normally retracted into the main body of the shelf and extends out when needed, which makes it convenient to pick up and put down materials. At the same time, it also reduces the need for aisle width and makes full use of space. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0023] Example: A telescopic shelving unit, such as Figure 1 As shown. This device includes a main shelf body 1, which includes several fixed frames 2, and movable supports 3 that can extend and retract relative to the fixed frames are provided on both sides of the fixed frames 2.

[0024] like Figure 2 , 4 As shown, the fixed frame 2 includes a column 21, with a top fixed shelf 22 at the top of the column. Three layers of guide sleeves 23 are fixedly installed from top to bottom on both ends of the column. Two guide sleeves 23 are installed at the same height in each layer, with the two guide sleeves 23 in the same layer located on opposite ends of the column, and the movable supports are installed in opposite directions. A fixed angle iron 24 is also provided on the end face of the column 21 for connecting struts between adjacent columns.

[0025] like Figure 3 , 4As shown, the movable support 3 includes a first telescopic arm 31 slidably inserted into the guide sleeve 23 and a second telescopic arm 34 disposed above the guide sleeve. The outer ends of both the first and second telescopic arms are welded and fixed to outer stop posts 36, which extend upwards above the second telescopic arm 34. An inner stop post 37 is also vertically disposed on the upper wall of the inner end of the second telescopic arm. The space between the outer stop post 36 and the inner stop post 37 is a material storage space 38.

[0026] like Figure 1 , 4 As shown, a rack 33 is provided in the middle of the lower wall of the outer end of the first telescopic arm 31. A drive shaft 4 is provided between the two ends of the shelf body 1. The drive shaft 4 passes through the lower part of the outer end of the guide sleeve 23. A gear is provided at the corresponding position of the drive shaft 4 and the rack 33. A mounting plate 26 is installed at the lower part of the outer end of the guide sleeve 23. The mounting plate 26 is provided with a drive shaft clearance groove 27 and a roller mounting hole 28. Rollers 29 supporting the lower walls of the first telescopic arm 31 are installed at the roller mounting holes 28. The rollers support from both sides, avoiding the position of the rack 33. A first roller 32 is provided at the inner end of the first telescopic arm 31. The upper surface of the first roller 32 is higher than the upper wall of the first telescopic arm, and the lower surface of the first roller is lower than the lower wall of the first telescopic arm. A second roller 35 is provided on the lower wall of the inner end of the second telescopic arm 34. A limiting baffle is provided on the upper wall of the guide sleeve that cooperates with the second telescopic arm.

[0027] A rocker shaft 5 is provided on the shelf body 1 above or below the end of the drive shaft 4. The rocker shaft and the drive shaft are connected by chain drive. A detachable rocker 6 is provided on the outer end of the rocker shaft.

[0028] When storing, the movable support retracts to its innermost position. When goods need to be stored or retrieved, a rocker arm drives the corresponding drive shaft to extend the movable support to the side of the main shelving unit. This allows the material storage position to protrude into the aisle relative to adjacent shelving units, facilitating easy access. This is especially beneficial for heavy materials such as steel pipes and rebars, which can be loaded and unloaded by dragging them from the end, saving time and effort and avoiding the risks associated with lifting materials. Furthermore, this shelving system reduces the required aisle width, allowing for more efficient use of factory space.
