Technical Field

[0001] This invention relates to the field of warehousing equipment technology, and in particular to a cantilever rack with adjustable structure. Background Technology

[0002] Cantilever racks are mainly composed of uprights, cantilever beams, and connecting rods. They are characterized by their lightweight, forward-extending cantilever structure and strong load-bearing capacity. They can significantly improve warehouse utilization and work efficiency when storing irregular or long materials. The cantilever can be single-sided or double-sided.

[0003] Cantilever racks are a type of warehouse racking system. They utilize specialized profile uprights and high-strength cantilever arms, suitable for storing various long, ring-shaped, sheet, and irregular materials. The cantilever arms can be single-sided or double-sided, featuring a lightweight structure and high load-bearing capacity. Back bracing enhances overall stability, and installation is simple with all necessary accessories. The modular structure, specialized profile uprights, back bracing for increased stability, and high-strength cantilever arms result in a lightweight design, high load-bearing capacity, and high space utilization. With added shelves, they are particularly suitable for small, low-ceiling warehouses, offering convenient management, a wide field of vision, and higher utilization compared to ordinary shelving.

[0004] Currently, cantilever racks on the market have a fixed structure and cannot adjust the angle and length of the cantilever in real time according to actual needs, resulting in a very limited range of applications. Moreover, once installed, they cannot be controlled or adjusted, leading to a limited range of ways to place and unload items on the racks. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an improved adjustable cantilever rack in order to solve the problems existing in the background art. This solves the problem that the cantilever racks on the market have a fixed structure, cannot adjust the angle and length of the cantilever in real time according to actual needs, resulting in a very limited range of applications. Moreover, once installed, they cannot be controlled and adjusted, resulting in a relatively simple way of placing and unloading items on the rack.

[0006] The technical solution adopted by the present invention to solve its technical problem is: an adjustable cantilever rack, including a main support, a first adjusting motor and a second adjusting motor. A lateral support frame is bolted to the inner side of the main support. An arc-shaped support cantilever controlled by the first adjusting motor is slidably mounted on the upper end of the lateral support frame. An arc-shaped internal adjusting compression frame controlled by the second adjusting motor is slidably mounted on the inner side of the arc-shaped support cantilever.

[0007] The main support has multiple lateral assembly through holes on its inner side. The lateral support frame includes a longitudinal assembly plate fixedly installed on the inner side of the main support by lateral bolts, an integral arc-shaped guide tube fixedly installed on the inner side of the longitudinal assembly plate, a first mounting seat fixed on the side wall of the arc-shaped guide tube, and a second mounting seat fixed on the side wall of the arc-shaped guide tube.

[0008] The arc-shaped guide tube has telescopic openings on both sides, and the arc-shaped support cantilever is inserted into the arc-shaped guide tube through the telescopic openings and slidably connected to the inner wall of the arc-shaped guide tube.

[0009] The outer surface of the arc-shaped guide tube has a lateral first transmission through hole corresponding to the position of the first mounting base. The upper surface of the arc-shaped guide tube has a lateral second transmission through hole corresponding to the position of the second mounting base. The inner surface of the arc-shaped guide tube has a lateral transmission groove with a built-in horizontal threaded rod on one side of the lateral first transmission through hole. The outer surface of the arc-shaped support cantilever has an arc-shaped adjusting tooth groove that meshes with the outer threaded surface of the horizontal threaded rod. The upper surface of the arc-shaped internal adjusting extrusion frame has an arc-shaped transmission tooth groove on its inner surface. The first adjusting motor is fixedly mounted on the upper end of the first mounting base by bolts. The second adjusting motor is fixedly mounted on one side of the second mounting base by bolts. The first transmission gear on the outer shaft of the first adjusting motor meshes with the conical tooth head on one side of the horizontal threaded rod by inserting into the lateral first transmission through hole. The second transmission gear on the outer shaft of the second adjusting motor meshes with the inner surface of the arc-shaped transmission tooth groove by inserting into the lateral second transmission through hole.

[0010] The upper arc-shaped support cantilever has two arc-shaped storage and adjustment slots for installing the arc-shaped internal adjustment and compression frame. The upper surface of the arc-shaped support cantilever has multiple arc-shaped limiting slots at the opening of the arc-shaped storage and adjustment slots. The upper surface of the arc-shaped internal adjustment and compression frame has an arc-shaped closed slot that cooperates with the arc-shaped limiting slot.

[0011] The aforementioned arc-shaped storage and adjustment groove is horizontally opened on the arc-shaped surface at the upper end of the arc-shaped support cantilever.

[0012] The lateral support frame has a lateral mounting slot on the side wall of the assembly surface that mates with the main bracket. The inner side of the lateral mounting slot has an integral assembly screw that mates with the lateral assembly through hole. The top of the assembly screw is threaded with a lateral locking nut for assembly locking on the outer side of the main bracket.

[0013] The outer wall of the arc-shaped internal adjustment extrusion frame is provided with a top storage slot with an upper opening on one side of the arc-shaped closed slot, and a flip-up isolation plate is elastically assembled inside the top storage slot.

[0014] The inner side of the top storage slot is provided with a circular lateral locking hole, and the outer side of the flip-up isolation plate has a circular protrusion that matches the circular lateral locking hole. The flip-up isolation plate is fixed to the inside of the top storage slot by the circular protrusion being inserted into the circular lateral locking hole.

[0015] The beneficial effects of this invention are:

[0016] (1) The adjustable cantilever rack of the present invention uses bolts to fix the lateral support frame of the built-in arc support cantilever on the inner side of the main support. The lateral support frame is adjusted and assembled by multiple longitudinally arranged lateral assembly through holes. Not only can the height of the cantilever be changed freely, but the number of cantilever can also be increased or decreased as needed, which facilitates the loading, unloading and adjustment of the rack.

[0017] (2) An arc-shaped internal adjustment squeezing frame is installed inside the arc-shaped support cantilever. The position of the arc-shaped internal adjustment squeezing frame can be adjusted to change the staggered position between the arc-shaped limiting slot and the arc-shaped closing slot, thereby changing the structure of the upper surface of the arc-shaped support cantilever. This allows for free adjustment of the placement stability of goods at the upper end of the arc-shaped support cantilever, and also facilitates the loading and unloading of goods.

[0018] (3) Two arc-shaped storage and adjustment slots for installing the arc-shaped internal adjustment extrusion frame are opened on the arc-shaped surface at the upper end of the arc-shaped support cantilever. The second adjustment motor is installed in the middle of the upper end of the arc-shaped support cantilever. The sliding of the arc-shaped internal adjustment extrusion frame on both sides can be controlled by a single motor at the same time. The control and adjustment operation is simple and the transmission efficiency is high.

[0019] (4) The first adjusting motor is fixed on the side wall of the arc-shaped guide tube through the first mounting base and the second adjusting motor is fixed on the second mounting base, making the installation of the drive mechanism more convenient and the structural layout more reasonable. The first adjusting motor is connected to the arc-shaped support cantilever through the horizontal threaded rod. While ensuring the transmission efficiency, the stability of the arc-shaped support cantilever can be guaranteed in the closed state, and the safety is greatly improved.

[0020] (5) A top storage slot for internal elastic installation of flip-up isolation plate is provided on one side of the arc-shaped closed card slot of the arc-shaped adjustment extrusion frame, thereby forming a partition on the upper surface of the cantilever, making the placement more diverse and applicable to a wider range of scenarios.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0028] Figure 1 , Figure 2 , Figure 3 and Figure 4 The adjustable cantilever rack shown includes a main support 1, a first adjusting motor 2 and a second adjusting motor 3. A lateral support frame is bolted to the inner side of the main support 1. An arc-shaped support cantilever 4 controlled by the first adjusting motor 2 is slidably mounted on the upper end of the lateral support frame. An arc-shaped internal adjusting compression frame 5 controlled by the second adjusting motor 3 is slidably mounted on the inner side of the arc-shaped support cantilever 4.

[0029] Furthermore, to facilitate installation, eight lateral mounting through holes 6 are provided on the inner side of the main bracket 1. The lateral support frame includes a longitudinal mounting plate 7 fixedly mounted on the inner side of the main bracket 1 by lateral bolts, an integral arc-shaped guide tube 8 fixedly mounted on the inner side of the longitudinal mounting plate 7, a first mounting seat 9 fixed on the side wall of the arc-shaped guide tube 8, and a second mounting seat 10 fixed on the side wall of the arc-shaped guide tube 8.

[0030] Furthermore, in order to facilitate assembly, telescopic ports are provided on both sides of the arc-shaped guide tube 8, and the arc-shaped support cantilever 4 is inserted into the arc-shaped guide tube 8 through the telescopic ports and slidably connected to the inner wall of the arc-shaped guide tube 8.

[0031] Furthermore, to facilitate transmission control, a lateral first transmission through hole 11 is provided on the outer surface of the arc-shaped guide tube 8 corresponding to the position of the first mounting base 9, and a lateral second transmission through hole 12 is provided on the upper surface of the arc-shaped guide tube 8 corresponding to the position of the second mounting base 10. A lateral transmission groove 14 with a built-in transverse threaded rod 13 is provided on the inner surface of the arc-shaped guide tube 8 on the side of the lateral first transmission through hole 11. An arc-shaped adjusting tooth groove 15 that meshes with the outer threaded surface of the transverse threaded rod 13 is provided on the outer surface of the arc-shaped internal adjusting extrusion frame 5. The first adjusting motor 2 is fixedly mounted on the upper end of the first mounting base 9 by bolts, and the second adjusting motor 3 is fixedly mounted on one side of the second mounting base 10 by bolts. The first transmission gear 17 on the outer shaft of the first adjusting motor 2 meshes with the tapered tooth head on one side of the horizontal threaded rod 13 through the insertion into the lateral first transmission through hole 11. The second transmission gear 18 on the outer shaft of the second adjusting motor 3 meshes with the inner side of the arc-shaped transmission groove 16 through the insertion into the lateral second transmission through hole 12.

[0032] Furthermore, in order to facilitate the adjustment of the structure of the upper end of the arc-shaped support cantilever 4 and change the smoothness of the upper end of the arc-shaped support cantilever 4 as needed, two arc-shaped storage and adjustment grooves 19 for installing the arc-shaped internal adjustment extrusion frame 5 are opened on the arc-shaped surface of the upper end of the arc-shaped support cantilever 4. Six arc-shaped limiting slots 20 are opened on the upper surface of the arc-shaped support cantilever 4 at the opening position of the arc-shaped storage and adjustment grooves 19. Arc-shaped closed slots 21 that cooperate with the arc-shaped limiting slots 20 are opened on the upper surface of the arc-shaped internal adjustment extrusion frame 5.

[0033] The position of the arc-shaped closed slot 21 is adjusted by sliding the arc-shaped internal adjusting extrusion frame 5 to adjust its position relative to the arc-shaped limiting slot 20. When the arc-shaped limiting slot 20 and the arc-shaped closed slot 21 are set in parallel and connected, a limiting groove is formed on the arc-shaped support cantilever 4. When objects are placed, they will fall into the limiting groove, thus improving stability. When the arc-shaped limiting slot 20 and the arc-shaped closed slot 21 are set in an alternating and non-connected manner, a smooth arc-shaped surface is formed on the arc-shaped support cantilever 4, which facilitates loading and unloading of goods.

[0034] Furthermore, to facilitate assembly and adjustment, two arc-shaped storage and adjustment slots 19 are horizontally opened on the arc-shaped surface at the upper end of the arc-shaped support cantilever 4.

[0035] There are two arc-shaped internal adjustment squeezing frames 5, which are respectively set on both sides of the second transmission gear 18. The positions of the two arc-shaped internal adjustment squeezing frames 5 are adjusted synchronously by rotating the second adjustment motor 3.

[0036] Furthermore, in order to improve the structural strength and stability of the assembly end, the lateral support frame is provided with a lateral mounting groove 22 on the side wall of the assembly surface to cooperate with the main bracket 1. The inner side of the lateral mounting groove 22 has an integral assembly screw 23 that cooperates with the lateral assembly through hole 6. The top of the assembly screw 23 is threaded with a lateral locking nut 24 for assembly locking on the outer side of the main bracket 1.

[0037] The lateral support frame is fitted onto the outside of the main bracket 1 via the lateral mounting slot 22. At the same time, the mounting screw 23 is inserted into the lateral mounting through hole 6, and then the lateral locking nut 24 is threaded onto the outside of the mounting screw 23 for rotation locking and fixation.

[0038] like Figure 2 and Figure 5 As shown, in order to form a partition at the upper end of the arc-shaped support cantilever 4 as needed, the outer wall of the arc-shaped internal adjustment extrusion frame 5 is provided with a top storage groove 25 with an upper opening on one side of the arc-shaped closed slot 21, and a flip-up partition plate 26 is elastically assembled inside the top storage groove 25.

[0039] The flip-up partition 26 flips upwards to form a limit through the inner wall of the top storage slot 25. The partition allows goods to be placed separately on the curved support cantilever 4.

[0040] Furthermore, in order to lock the angle of the flip-up partition plate 26, a circular lateral locking hole 27 is provided on the inner side of the top storage groove 25, and a circular protrusion 28 is provided on the outer side of the flip-up partition plate 26 to cooperate with the circular lateral locking hole 27. The flip-up partition plate 26 is inserted into the circular lateral locking hole 27 through the circular protrusion 28 and is fixedly engaged with the inside of the top storage groove 25.

[0041] People manually move the flip-up partition 26 to flip it into the top storage slot 25, and then use the circular protrusion 28 to engage with the circular lateral locking hole 27 to lock it in place. A lateral rotating shaft is fixed on the inner side of the top storage slot 25. The flip-up partition 26 is then connected to the top storage slot 25 by fitting it onto the lateral rotating shaft through the internal mounting hole. A lateral torsion spring is then installed on the lateral rotating shaft to drive the flip-up partition 26 to elastically flip and reset.

[0042] Adjustment principle: The first adjusting motor 2 and the second adjusting motor 3 are independently controlled to open, close, and rotate forward and backward via an external power supply and an external control switch. When the first adjusting motor 2 rotates forward, it drives the arc-shaped support cantilever 4 to move from left to right along the arc-shaped guide tube 8; when the first adjusting motor 2 rotates backward, it drives the arc-shaped support cantilever 4 to move from right to left along the arc-shaped guide tube 8; when the second adjusting motor 2 rotates forward, it drives the two arc-shaped internal adjusting extrusion frames 5 on the upper surface of the arc-shaped support cantilever 4 to move in the opposite direction toward the center; when the second adjusting motor 2 rotates backward, it drives the two arc-shaped internal adjusting extrusion frames 5 on the upper surface of the arc-shaped support cantilever 4 to move in the opposite direction toward the sides.

[0043] An adjustable cantilever rack of the present invention uses bolts to fix the lateral support frame of the built-in arc-shaped support cantilever 4 to the inner side of the main bracket 1. Multiple longitudinally arranged lateral assembly through holes 6 allow for adjustment and assembly of the lateral support frame, enabling not only free adjustment of the cantilever height but also the addition or reduction of the number of cantilever arms as needed, facilitating rack loading, unloading, and adjustment. An arc-shaped internal adjusting compression frame 5 is installed inside the arc-shaped support cantilever 4. Adjusting the position of the arc-shaped internal adjusting compression frame 5 changes the staggered position between the arc-shaped limiting slot 20 and the arc-shaped closing slot 21, thereby altering the structure of the upper surface of the arc-shaped support cantilever 4. This allows for free adjustment of the stability of goods placed on the upper end of the arc-shaped support cantilever 4 and facilitates loading and unloading. Two arc-shaped storage and adjustment slots 19 are provided on the arc-shaped surface at the upper end of the arc-shaped support cantilever 4 for installing the arc-shaped internal adjusting compression frame 5. The second adjusting motor 3 is installed at the middle of the upper end of the arc-shaped support cantilever 4, so that the sliding of the arc-shaped internal adjusting extrusion frame 5 on both sides can be controlled simultaneously by a single motor. The control and adjustment operation is simple and the transmission efficiency is high. The first adjusting motor 2 is fixed to the side wall of the arc-shaped guide tube 8 through the first mounting base 9 and the second adjusting motor 3 is fixed through the second mounting base 10, which makes the installation of the drive mechanism more convenient and the structural layout more reasonable. The first adjusting motor 2 is connected to the arc-shaped support cantilever 4 through the transverse threaded rod 13. While ensuring the transmission efficiency, it can ensure the stability of the arc-shaped support cantilever 4 in the closed state, which greatly improves the safety. A top storage slot 25 for the internal elastic installation flip isolation plate 26 is opened on one side of the arc-shaped closed slot 21 of the arc-shaped internal adjusting extrusion frame 5, thereby forming a partition on the upper surface of the cantilever, making the placement more diversified and the application scenarios more extensive.

[0044] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
