TECHNICAL FIELD
[0001] The utility model relates to the technical field of logistics storage, specifically a buffer rack for a storage rack. BACKGROUND
[0002] A buffer rack for a storage rack is arranged in a storage rack system and is used as auxiliary equipment for temporarily storing and staging goods to regulate the logistics rhythm and balance the efficiency of goods in and out. It is usually composed of a frame, a tray support structure, a conveying device (such as a roller or a belt) or a sorting mechanism, and can play a role when goods are temporarily stored in the warehouse, sorted out of the warehouse or connected in different logistics links. For example, when the goods to be stored in the warehouse need to be stored on the shelf, or the goods to be delivered out of the warehouse need to be sorted and delivered according to the order, the buffer rack can temporarily store the goods to avoid logistics congestion or idle equipment.
[0003] In the field of warehouse logistics, the buffer rack is a key device for connecting goods in and out of the warehouse, and its versatility directly affects the efficiency of the warehouse. The buffer racks matched with existing storage racks are mostly designed with fixed structures, and the size of the tray and the support spacing cannot be dynamically adjusted according to the specifications of the goods. When facing goods of different lengths (such as standard trays, small cartons or irregular shapes), space is often wasted due to "large storage of small goods", or the risk of goods falling due to "small storage of large goods". Although some adjustable buffer racks have simple telescopic functions, the adjustment precision is insufficient and the operation is cumbersome, which requires manual tools for assistance and is difficult to adapt to the rapid switching requirements in high-frequency logistics scenarios, resulting in high idle rate of equipment and poor compatibility. Therefore, an intelligent buffer rack structure that can adapt to different sizes of goods is needed to improve the flexible adaptation capability of the warehouse system. SUMMARY

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] Please refer to Figures 1-4 The utility model provides a kind of technical scheme:
[0023] Please refer to Figures 1-4 As shown in the figure, a kind of buffer rack for warehouse rack, including second plate 3, first plate 4, slidingly set in the inside of second plate 3, another side of first plate 4 is fixedly installed with third plate 5, guide rail 13 is opened on first plate 4, multiple triangular blocks 11 are linearly arranged in the inside of guide rail 13;Telescopic rod 8, fixedly installed on second plate 3, telescopic end of second plate 3 is installed with U-shaped frame 10, roller is rotatably arranged on U-shaped frame 10, and tension spring 9 is fixedly installed between second plate 3 and U-shaped frame 10;Pull rope 7, fixedly installed on U-shaped frame 10, another end of pull rope 7 is rotatably arranged on T-shaped rod 6.
[0024] When the length of buffer rack needs to be adjusted, first plate 4 is extracted from second plate 3, roller rolls along guide rail 13 and extrudes the inclined surface of triangular block 11, drives U-shaped frame 10 to move backward against the tension of tension spring 9, rotates T-shaped rod 6 by pull rope 7 traction, and then pulls first plate 4 to slide in second plate 3, so that third plate 5 is synchronized with first plate 4 to extend or retract, until roller is positioned into the right angle surface of adjacent triangular block 11 to realize positioning, and the length of buffer rack is adjusted to adapt to the size of goods;Telescopic rod 8 provides support for U-shaped frame 10, and tension spring 9 ensures that roller and triangular block 11 always abut, forming a lockable elastic adjustment structure.
[0025] Through the sliding fit of the first plate 4 and the third plate 5, the size of the buffer rack can be automatically adjusted for different lengths of goods, solving the space waste of "large goods small storage" and the sliding risk of "small goods large storage"; the positioning accuracy of the triangular block 11 and the roller is within 10 mm, which is better than the error of the traditional adjustable buffer rack, and the quick adjustment can be realized; the elastic combination of the tension spring 9 and the telescopic rod 8 makes the adjustment process smooth and stable, adapts to the size switching demand of goods in the high-frequency logistics scene, reduces the idle rate of the equipment by more than 40%, and improves the flexible adaptation ability of the warehouse system to different goods such as standard pallets and small cartons.
[0026] Referring to Figure 3 , the cross section of the triangular block 11 is set as a right triangle, and the inclined surface of the triangular block 11 is set towards the direction of the third plate 5.
[0027] The cross section of the triangular block 11 is set as a right triangle and the inclined surface faces the third plate 5, which can make the roller push the first plate 4 along the inclined surface to drive the third plate 5 to extend outward when the roller rolls along the guide rail 13, realizing the automatic adjustment of the length of the buffer rack according to the size of the goods. When the roller rolls over the triangular block 11, the right angle surface can stop the roller to form positioning, preventing the first plate 4 from sliding back due to the weight of the goods, and ensuring the stability of the adjusted structure. This design uses the guiding effect of the inclined surface of the triangle and the locking function of the right angle surface to complete the self-adaptive adjustment and positioning without manual operation, solving the problems of low adjustment accuracy and complicated operation of the traditional buffer rack, and improving the adaptation ability to different sizes of goods.
[0028] Referring to Figure 1 , the bottom of the second plate 3 is fixedly installed with a mounting bracket 12, and the T-shaped rod 6 is rotationally arranged on the mounting bracket 12.
[0029] The mounting bracket 12 fixed at the bottom of the second plate 3 provides a rotating support basis for the T-shaped rod 6, so that the T-shaped rod 6 can rotate flexibly on the mounting bracket 12. When the U-shaped frame 10 moves backward under the pressure of the goods, the T-shaped rod 6 is rotated on the mounting bracket 12 through the traction of the pull rope 7, so as to convert the linear tension of the pull rope 7 into the rotary power of the T-shaped rod 6, and then drive the first plate 4 to slide in the second plate 3. This structure design ensures the stability and accuracy of force transmission, so that the T-shaped rod 6 becomes the transmission hub between the pull rope 7 and the first plate 4 under the support of the mounting bracket 12, ensuring the reliability of force transmission in the self-adaptive adjustment process of the buffer rack, and avoiding the adjustment failure problem caused by loose transmission structure.
[0030] Referring to Figure 2 , the side surfaces of the second plate 3 and the third plate 5 are provided with supports 1, the L-shaped blocks 2 are fixedly installed on the supports 1, and the bottoms of the second plate 3 and the third plate 5 are fixedly provided with insertion holes matched with the vertical ends of the L-shaped blocks 2.
[0031] The second plate 3 and the third plate 5 side of the support 1 and the L-shaped block 2 fixed thereon provide a vertical support foundation for the buffer rack, and the bottom of the two is matched with the insertion hole of the vertical end of the L-shaped block 2, so that the second plate 3 and the third plate 5 can be rigidly connected with the L-shaped block 2 through the plug-in mode. This structure design not only ensures the stability of the overall frame during length adjustment of the buffer rack, but also guides the plate to slide smoothly in the vertical direction through the cooperation of the insertion hole and the vertical end, avoiding deviation or shaking during adjustment. At the same time, the modular plug-in structure facilitates the disassembly and maintenance of the buffer rack, and can quickly combine or split according to the storage space requirements, improving the installation convenience and use flexibility of the equipment.
[0032] Referring to Figures 1-2 , a support plate is fixedly installed between the two L-shaped blocks 2, and the top of the support plate abuts against the bottom of the second plate 3.
[0033] The top of the support plate fixed between the two L-shaped blocks 2 abuts against the bottom of the second plate 3, which can provide continuous support force when adjusting the length of the second plate 3 and the third plate 5, preventing the plate from deforming due to the weight of the goods, and ensuring the stability of the overall structure of the buffer rack. At the same time, the support plate can limit the vertical movement range of the second plate 3, so that the plate remains stable during horizontal adjustment, avoiding affecting the positioning accuracy of the roller and the triangular block 11 due to shaking. This design enhances the load-bearing capacity and structural rigidity of the buffer rack, so that it can maintain reliable support performance when adapting to goods of different sizes.
[0034] Referring to Figure 3 , the width of the guide rail 13 is matched with the width of the roller.
[0035] The width of the guide rail 13 is matched with the width of the roller, so that the roller can smoothly roll in the guide rail 13 without left or right deviation, ensuring that the force transmission direction is accurate when the roller presses the inclined surface of the triangular block 11, thereby ensuring that the sliding adjustment process of the first plate 4 driving the third plate 5 is stable, avoiding adjustment jamming or positioning deviation caused by too large gap between the roller and the guide rail 13. This precisely matched structure design improves the reliability and stability of the self-adaptive adjustment of the buffer rack, so that the equipment can accurately respond to the temporary storage needs of goods of different sizes.
[0036] Referring to Figures 3-4 , a sponge layer is arranged on the T-shaped rod 6.
[0037] The sponge layer arranged on the T-shaped rod 6 can play a buffering role when the T-shaped rod 6 is rotated by the pull rope 7, reducing the friction loss between the pull rope 7 and the T-shaped rod 6, prolonging the service life of the pull rope 7, and the elastic contact of the sponge layer can reduce the noise generated during rotation, making the buffer rack run more smoothly during adjustment. In addition, the sponge layer can also prevent the pull rope 7 from slipping on the surface of the T-shaped rod 6, ensuring the efficiency of force transmission and improving the reliability of the self-adaptive adjustment process.
[0038] With reference to Figures 1-2 The material of the bracket 1 and the first plate 4 is stainless steel.
[0039] The bracket 1 and the first plate 4 are made of stainless steel, which can adapt to the humid, dusty and other working conditions that may occur in the storage environment by virtue of the excellent corrosion resistance of stainless steel, avoid the structure strength of the bracket 1 and the first plate 4 from being reduced due to rust, and ensure that the buffer rack is not easy to deform when bearing goods, thereby maintaining the smoothness of the sliding adjustment of the first plate 4. The material selection not only prolongs the service life of the equipment, but also ensures the structural stability and adjustment reliability of the buffer rack in long-term use.
[0040] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process conversion, or direct or indirect application in other related technical fields, as described in the specification and drawings of the present application, are also included in the patent protection range of the present application.
