Description

Technical Field

[0001] This invention relates to the field of LED display technology, and more particularly to a transport box for holding and transporting LED displays. Background Technology

[0002] Currently, metal transport cases similar to flight cases are generally used for packing and transporting LED displays. There are two common methods for placing LED displays inside these cases: horizontal and vertical. When placed vertically, if the LED display is too large and the worker's height is limited, it becomes impossible for one person to remove it independently. When placed horizontally, inserting or removing the LED display from the bottom of the case often requires bending over, and due to limited space, the LED display must generally be kept horizontal to ensure smooth insertion or removal. This inevitably affects the user experience and efficiency of inserting or removing the LED display. Summary of the Invention

[0003] In view of the above problems, embodiments of the present invention are proposed to provide a transport box that solves or at least partially solves the above problems.

[0004] This invention provides a transport box, which includes:

[0005] Box;

[0006] The lifting mechanism is located inside the housing and includes a rotating wheel, a spring balancer, and a transmission component. Two rotating wheels are positioned opposite each other and spaced apart near the top of the housing. A spring balancer is located below each rotating wheel. One end of each of the two transmission components is connected to the spring balancer, and the other end of each transmission component extends past the rotating wheel above the spring balancer and toward the bottom of the housing.

[0007] Among them, on the opposite side of the two transmission components, there are multiple brackets extending towards each other for placing the LED display screen. Under the action of the spring balancer, the transmission components can drive the brackets to reciprocate up and down.

[0008] Furthermore, the wheel includes a gear, and the transmission component includes interconnected steel wire ropes and a rack capable of meshing with the gear;

[0009] The end of the wire rope away from the rack is connected to the spring balancer, and multiple brackets are spaced apart on the side of the rack opposite to the gear.

[0010] Furthermore, the brackets from the nearest gear to the nearest spring balancer are the first bracket to the Nth bracket;

[0011] Under the action of the spring balancer, when all the LED displays are placed on all the brackets, the first bracket is in the position closest to the gear; when the LED displays on the first bracket are removed, the second bracket will rise to the position closest to the gear; when all the LED displays on all the brackets are removed, the Nth bracket will rise to the position closest to the gear.

[0012] Furthermore, the bracket is provided with a support rod that matches the side shape of the LED display screen.

[0013] Furthermore, it also includes a synchronizing link, the two ends of which are respectively connected to two opposing gears.

[0014] Furthermore, it also includes two opposing frames disposed inside the housing. Each frame includes multiple reinforcing rods and a mounting rod disposed at the top of the frame. The gear is disposed on the mounting rod, and the spring balancer is disposed at the bottom of the frame.

[0015] The multiple reinforcing rods are spaced apart between the spring balancer and the mounting rod.

[0016] Furthermore, at least three sets of the gears, the spring balancer, the rack, and the wire rope are provided within one of the frames;

[0017] Multiple connecting rods are spaced apart along the height of the frame, and each connecting rod is connected to at least three racks and moves back and forth with them.

[0018] Furthermore, a groove is provided on the opposite side of the frame, and the two ends of the connecting rod located at the bottom of the frame pass through the groove.

[0019] Furthermore, it also includes a tray, which is disposed between and connected to the two Nth brackets.

[0020] Furthermore, at least two sets of the lifting mechanisms are arranged side by side along the width direction inside the box.

[0021] Furthermore, it also includes a top cover, one side of the bottom of the top cover being hinged to one side of the top of the box, and the other side of the bottom of the top cover being connected to the other side of the top of the box via a first latch.

[0022] Furthermore, the box body has double doors on the wall surface where the first latch is located. The opposite sides of the double doors are hinged to the side wall of the box body, and the opposite sides of the double doors are connected by a second latch.

[0023] In the technical solution provided by this embodiment of the invention, a lifting mechanism is disposed inside the housing, including a rotating wheel, a spring balancer, and a transmission component.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] Please refer to Figure 1 This is a three-dimensional structural diagram of a transport box provided by an embodiment of the present invention. The transport box is used to hold an LED display screen and includes a box body 10 and a lifting mechanism 20. The lifting mechanism 20 is disposed inside the box body 10 and includes a rotating wheel 210, a spring balancer 220, and a transmission component 230. Two rotating wheels 210 are positioned opposite each other and spaced apart near the top of the box body 10. A spring balancer 220 is correspondingly provided below each rotating wheel 210. One end of each of the two transmission components 230 is connected to the spring balancer 220, and the other end of each transmission component 230 extends past the rotating wheel 210 above the spring balancer 220 and extends towards the bottom of the box body 10. On the opposite side of the two transmission components 230, there are multiple brackets 2301 extending towards each other for placing the LED display screen. Under the action of the spring balancer 220, the transmission components 230 can drive the brackets 2301 to reciprocate and move up and down.

[0034] Specifically, please combine Figure 2-5The housing 10 is generally made of metal materials such as iron and aluminum, and its shape is generally square with a space for accommodating multiple LED displays. The lifting mechanism 20 is set on the inner wall of the housing 10. The rotating wheel 210 is located near the top of the housing 10, and the spring balancer 220 is correspondingly located below the rotating wheel 210. The transmission component 230 is belt-shaped, with one end connected to the spring balancer 220 and the other end extending upward past the rotating wheel 210 and downward to a position near the bottom of the housing 10. The rotating wheel 210 and the spring balancer 220 are connected to the rotating wheel 210. The transmission components 230 are arranged in groups, with four or more groups corresponding to the four corners of the LED display screen inside the housing 10. Multiple brackets 2301 are spaced apart on opposite sides of two transmission components 230. The brackets 2301 on opposite transmission components 230 extend towards each other to support opposite sides of the LED display screen. That is, the LED display screen can be horizontally supported by the four brackets 2301 on the four transmission components 230. The spring balancer 220 exerts a certain pulling force on the transmission components 230, ensuring that the LED display screen is not placed on the housing 10. When the LED display is placed on bracket 2301, under the pulling force of the spring balancer 220, part of the transmission component 230 retracts into the spring balancer 220. This causes the bracket 2301 furthest from the spring balancer 220 on the transmission component 230 to rise to the position closest to the rotating wheel 210, that is, close to the top of the housing 10. If the first LED display is then placed on the bracket 2301 closest to the rotating wheel 210, the transmission component 230 will move downward by a threshold distance under the gravity of the first LED display. This threshold distance can maintain... The bracket 2301 adjacent to the top of the first LED display screen is moved to the position closest to the turntable 210, that is, close to the top of the housing 10, so as to place the second LED display screen. After the second LED display screen is placed on the bracket 2301 closest to the turntable 210, the transmission component 230 will continue to move downward by a threshold distance under the gravity of the first and second LED display screens. This is repeated until the first LED display screen moves to the position close to the bottom of the housing 10, and the housing 10 can then be filled with LED display screens.When it is necessary to remove the full LED display screen from the housing 10, after the top LED display screen is removed, the transmission component 230 will move towards the spring balancer 220 under the action of the pulling force, causing the remaining LED display screens to move upward, so that there is always an LED display screen near the top of the housing 10. By repeating this process, multiple LED display screens installed in the housing 10 can be removed from the top of the housing 10.

[0035] Thus, in this embodiment of the invention, when placing the LED display screen into the housing 10 or taking the LED display screen out of the housing 10, the lifting mechanism 20 can be used to place or take out the LED display screen near the top of the housing 10, avoiding bending over and effectively improving the operation experience and efficiency of placing or taking out the LED display screen.

[0036] Furthermore, in other preferred embodiments of the present invention, the wheel 210 includes a gear 2101, and the transmission member 230 includes interconnected wire ropes 2302 and a rack 2303 capable of meshing with the gear 2101.

[0037] The end of the wire rope 2302 away from the rack 2303 is connected to the spring balancer 220, and a plurality of brackets 2301 are spaced apart on the side of the rack 2303 opposite to the gear 2101.

[0038] Specifically, the gear 2101 has multiple protruding teeth on its outer periphery, and the rack 2303 has multiple grooves for accommodating the protruding teeth, thereby enabling the gear 2101 and the rack 2303 to mesh with each other; the wire rope 2302 is disposed between the rack 2303 and the spring balancer 220, and the wire rope 2302 can retract into the spring balancer 220 under the tension of the spring balancer 220, and can extend out of the spring balancer 220 under the gravity of the LED display screen; multiple brackets 2301 are spaced apart along the length direction of the rack 2303 on the side of the rack 2303 opposite to the gear 2101, so that the brackets 2301 on two opposite racks 2303 can lift the LED display screen.

[0039] Further, in other preferred embodiments of the present invention, the first bracket 23011 to the Nth bracket 2301N are arranged sequentially from the direction closest to the gear 2101 to the direction closest to the spring balancer 220; under the action of the spring balancer 220, when all brackets 2301 are equipped with LED displays, the first bracket 23011 is in the position closest to the gear 2101; when the LED displays on the first bracket 23011 are removed, the second bracket 23012 will rise to the position closest to the gear 2101; when all brackets 2301 are removed, the Nth bracket 2301N will rise to the position closest to the gear 2101.

[0040] Specifically, along the length of the gear 2101, from top to bottom, are the first bracket 23011, the second bracket 23012, ..., the Nth bracket 2301N; wherein, under the action of the spring balancer 220, when all brackets 2301 are equipped with LED displays, that is, when the housing 10 is full of LED displays, the first bracket 23011 is in the position closest to the gear 2101. At this time, the LED display on the first bracket 23011 is removed, and the Nth bracket 2301N... The second bracket 23012 will rise to the position closest to the gear 2101 under the action of the spring balancer 220, so as to remove the LED display screen from the second bracket 23012. This process can be repeated to remove all the remaining LED display screens from the position closest to the gear 2101. After all the LED display screens on the brackets 2301 have been removed, the Nth bracket 2301N will rise to the position closest to the gear 2101, at which point the housing 10 will be in an empty state.

[0041] Furthermore, in other preferred embodiments of the present invention, in order to improve the stability of the LED display screen placed on the bracket 2301, a support rod 201 matching the side shape of the LED display screen is provided on the bracket 2301. In a feasible embodiment, the support rod 201 has an upward groove to accommodate the frame of the LED display screen.

[0042] Furthermore, in other preferred embodiments of the present invention, a synchronizing link 30 is also included, the two ends of which are respectively connected to two opposing gears 2101.

[0043] Specifically, the two ends of the synchronizing link 30 are respectively connected to two opposing gears 2101 to ensure that the racks 2303 on both sides of the LED display screen can move up and down synchronously, so as to prevent the LED display screen from shifting during the lifting process.

[0044] Furthermore, in other preferred embodiments of the present invention, two opposing frames 40 are also included, disposed within the housing 10. Each frame 40 includes multiple reinforcing rods 401 and a mounting rod 402 disposed at the top of the frame 40. The gear 2101 is disposed on the mounting rod 402, and the spring balancer 220 is disposed at the bottom of the frame 40.

[0045] The multiple reinforcing rods 401 are spaced apart between the spring balancer 220 and the mounting rod 402.

[0046] Specifically, two opposing frames 40 are respectively disposed inside the housing 10, and the two are separated by a certain distance, which is adapted to the width of the LED display screen. The top of the frame 40 is provided with a mounting rod 402 for mounting the gear 2101, and the bottom of the frame 40 is provided at a position corresponding to the gear 2101. The frame 40 between the spring balancer 220 and the mounting rod 402 is also provided with multiple reinforcing rods 401 at intervals to strengthen the frame 40.

[0047] Furthermore, in other preferred embodiments of the present invention, at least three sets of the gears 2101, the spring balancer 220, the rack 2303, and the wire rope 2302 are provided within one of the frames 40;

[0048] Multiple connecting rods 403 are spaced apart along the height direction of the frame 40. Each connecting rod 403 is connected to at least three racks 2303 and moves back and forth with them.

[0049] Specifically, three gears 2101 are arranged side-by-side on the mounting rod 402, and three spring balancers 220 are correspondingly provided on the frame 40. Three racks 2303 and the wire rope 2302 are also connected to the gears 2101 and the spring balancers 220. Multiple connecting rods 403 are spaced apart along the height of the frame 40, and each connecting rod 403 is connected to at least three racks 2303 and can reciprocate with the racks 2303. Here, the connecting rods 403 connect multiple racks 2303 into a whole, enabling them to reciprocate as a whole, thereby improving the stability of the LED display screen during lifting and lowering.

[0050] Furthermore, in other preferred embodiments of the present invention, a groove 404 is provided on the opposite side of the frame 40, and the two ends of the connecting rod 403 located at the bottom of the frame 40 respectively pass through the groove 404.

[0051] Specifically, the slide groove 404 is disposed on the side of the frame 40 on both sides of the moving direction of the rack 2303, and opposite to the connecting rod 403; the two ends of the connecting rod 403 located at the bottom of the frame 40 respectively pass through the slide groove 404 and can reciprocate up and down within the slide groove 404. This design ensures that the rack 2303 and the bracket 2301 can only reciprocate in the height direction of the frame 40, while preventing the rack 2303 and the bracket 2301 from moving in the left and right directions, thereby improving the stability of the LED display screen during placement and lifting.

[0052] Furthermore, in other preferred embodiments of the present invention, a tray 50 is also included, which is disposed between and connected to the two Nth brackets 2301N.

[0053] Here, the tray 50 is positioned between the two frames 40, specifically with its opposite sides connected to the two Nth brackets 2301N, thereby ensuring that there is sufficient space between the two frames 40 to accommodate the LED display screen.

[0054] Furthermore, in other preferred embodiments of the present invention, at least two sets of the lifting mechanisms 20 are arranged side by side along the width direction inside the housing 10. This design allows multiple sets of LED displays to be placed simultaneously within one housing 10, thereby improving the utilization efficiency of the housing 10.

[0055] Furthermore, in other preferred embodiments of the present invention, a top cover 60 is also included, one side of the bottom of the top cover 60 being hinged to one side of the top of the housing 10, and the other side of the bottom of the top cover 60 being connected to the other side of the top of the housing 10 via a first latch (not shown in the figure).

[0056] Specifically, the top cover 60 is fastened to the box body 10, and one side of the bottom of the top cover 60 is connected to one side of the top of the box body 10 by a hinge, so that the top cover 60 can be flipped upward to open the box body 10; in addition, the other side of the bottom of the top cover 60 is connected to the other side of the top of the box body 10 by the first latch, which ensures the safety of the box body 10 during use.

[0057] Furthermore, in other preferred embodiments of the present invention, the wall surface of the housing 10 where the first latch is provided is provided with double doors 110, the opposite sides of the double doors 110 are hinged to the side wall of the housing 10, and the opposite sides of the double doors 110 are connected by a second latch (not shown in the figure).

[0058] Specifically, the double doors 110 are formed on the wall of the housing 10 where the first latch is located. The sides of the double doors 110 that are far apart from each other are connected to the side wall of the housing 10 by hinges. This design allows the housing 10 to be opened from the side, which allows the LED display screen to be placed and removed from the side, and also facilitates the installation and maintenance of the lifting mechanism 20. The sides of the double doors 110 that are close to each other are connected by the second latch. This design further ensures the safety of the housing 10 during use.

[0059] In addition, in other preferred embodiments of the present invention, the bottom of the box 10 is provided with a plurality of rollers 70 capable of driving the box 10 to move.

[0060] The top cover 60 is provided with a plurality of grooves 80 that can accommodate the rollers 70.

[0061] Specifically, multiple rollers 70 are connected to the bottom of the box body 10, generally located at the four corners of the bottom of the box body 10 to ensure stability when the box body 10 is moved by the rollers 70; in addition, multiple grooves 80 are provided on the surface of the top cover 60. These grooves 80 are for accommodating the rollers 70 at the bottom of the upper box body 10 when two transport boxes are stacked, preventing the upper box body 10 from slipping and improving the safety of stacking the transport boxes.

[0062] In addition, the roller 70 mentioned here can be a non-powered wheel, which moves the transport box by means of external force; or it can be a driven wheel, which moves the transport box by its own movement. The roller 70 also includes a swivel wheel for steering.

[0063] Furthermore, a handle 90 is provided on the side wall of the box 10 to facilitate manual handling or hoisting of the box 10.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, and are not intended to limit them. Although the embodiments of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
