Description

Technical Field

[0001] The invention relates to the technical field of compact shelving, in particular to a double-layer compact shelving with an anti-dumping function. Background Art

[0002] Compact shelving is often used to store archival documents. It usually has tracks at the bottom so that multiple compact shelving can slide on the tracks, so that they can be placed close together to save space. However, when the compact shelving slides on the tracks, it is easy to topple over due to reasons such as too fast speed or unstable center of gravity.

[0003] In the prior art, when the compact shelving is moved, it is necessary to manually rotate the turntable to make it move on the slide rail, so as to realize the movement of the compact shelving. However, in the prior art, when the compact shelving is moved, it is necessary to manually rotate the turntable to make the compact shelving move in the slide rail, which not only requires manual labor to follow the direction of movement of the compact shelving, but also consumes manual labor and is prone to tipping or overturning. The tipping of the compact shelving may cause the life of the staff and cause damage or confusion to the stability of the inside of the compact shelving, which will not only cause work stagnation but also cause file loss and file damage, affecting work progress and work efficiency.

[0004] In addition, the prior art only uses springs to provide shock absorption protection for the compact shelving when it tips over. However, when there are too many documents inside the compact shelving, the shock absorption effect of the springs may deteriorate due to the weight of the compact shelving, which not only reduces the protective effect of the compact shelving but may also cause secondary damage to the compact shelving. Furthermore, the prior art does not propose to clear obstacles in front of the compact shelving. If there are obstacles in front of the compact shelving while it is moving, it may cause the compact shelving to stop moving and may also cause the compact shelving to tip over.

This limiting function can ensure that the compact shelving can avoid safety hazards caused by excessive movement during movement, such as tipping over and sliding. Clearing obstacles in front of the compact shelving can ensure smooth traffic in the front and effectively prevent the compact boxes from being blocked from moving. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiments of the present invention

[0036] Please refer to Figures 1 to 6 As shown:

A double-layer compact shelving with an anti-dumping function comprises: a reciprocating obstacle clearing mechanism 6 and a limit inflation mechanism 7;

[0038] The reciprocating obstacle clearing mechanism 6 is arranged on the side of the rack 3, and the reciprocating obstacle clearing mechanism 6 is used to clear obstacles in front of the compact rack 5 and squeeze the documents of the compact rack 5;

[0039] The position-limiting air-inflating mechanism 7 is arranged at the rear of the compact shelving 5 , and the position-limiting air-inflating mechanism 7 is used for protecting and limiting the position of the compact shelving 5 when it is tipped over.

[0040] The reciprocating obstacle clearing mechanism 6 includes a screw rod 606 , which is fixedly connected to the output end of the external motor. A second gear 602 is fixedly connected to the surface of the screw rod 606 close to the external motor, and a rotating column 603 is fixedly connected to the surface of the second gear 602 .

[0041] The surface of the rotating column 603 is meshedly connected with a toothed plate 601, and the toothed plate 601 is slidably connected to the surface of the wall 1. The surface of the compact rack 5 is fixedly connected with a first shock-absorbing column 605, and the side of the toothed plate 601 is fixedly connected with an obstacle removal plate 604.

[0042] A moving block 607 is threadedly connected to the surface of the screw rod 606, and a swing rod 608 is rotatably connected to the surface of the moving block 607 via a pin shaft. One end of the swing rod 608 away from the moving block 607 is rotatably connected to a first moving plate 613 via a pin shaft. A storage rack 609 is fixedly connected to the surface of the first moving plate 613, and a telescopic column 610 is fixedly connected to the surface of the storage rack 609.

[0043] The end of the telescopic column 610 away from the storage rack 609 is fixedly connected to the inner wall of the compact shelving 5. A sliding groove 612 is provided on the side inner wall of the compact shelving 5. A pressing plate 611 is slidably connected to the surface of the first movable plate 613.

This can help staff members to complete document sorting work more easily and reduce their workload.

[0046] Further Embodiments

[0047] Please refer to Figure 6 and Figure 7 As shown:

[0048] The limiting inflation mechanism 7 includes a telescopic plate 701, which is fixedly connected to the top of the compact shelving 5, a wedge-shaped extrusion block 702 is fixedly connected to the bottom of the telescopic plate 701, a fixed plate 706 is fixedly connected to the surface of the compact shelving 5, an airbag 704 is fixedly connected to the side of the fixed plate 706, a second shock-absorbing column 705 is fixedly connected to the surface of the airbag 704, and a wedge-shaped compression plate 703 is slidably connected to the side of the airbag 704 away from the second shock-absorbing column.

[0049] A second movable plate 707 is fixedly connected to the side of the compact shelving 5, and a sliding groove is provided on the surface of the second movable plate 707. The sliding groove provided on the second movable plate 707 is slidably connected to a limited sliding plate 712. The limited sliding plate 712 is fixedly connected to the surface of the wall 1. The surface of the second movable plate 707 is rotatably connected to a swing plate 708 via a pin shaft.

[0050] The surface of the swing plate 708 is rotatably connected to a swing limit plate 709 via a pin shaft, and both ends of the swing limit plate 709 are rotatably connected to sliding columns 710 via pin shafts. The surface of the sliding column 710 is slidably connected to a rectangular plate 711, which is fixedly connected to the surface of the wall 1, and an inclined U-shaped sliding groove is opened inside the rectangular plate 711.

[0051] Among them: four groups of second shock-absorbing columns 705 are respectively arranged along the four corners of the surface of the airbag 704, and two groups of U-shaped sliding grooves are opened at both ends of the rectangular plate 711, and two groups of sliding grooves are opened on the surface of the second movable plate 707;

[0052] The effects achieved by this embodiment are as follows: in the prior art, when there are too many documents inside the compact shelving 5 and it overturns, the weight of the compact shelving 5 may cause the spring shock-absorbing effect to deteriorate, which not only reduces the protective effect of the compact shelving but may also cause secondary damage to the compact shelving. Compared with the prior art, through the coordinated use of the wedge-shaped extrusion block 702, the airbag 704 and the second shock-absorbing column 705, it is possible to effectively achieve the shock absorption of the compact shelving 5 when it topples over while also enabling the airbag 704 to open. When the compact shelving 5 topples over due to external force or other reasons, the shock-absorbing function can effectively reduce the speed and impact force of the toppleover of the compact shelving 5, thereby reducing the risk of personal injury. The design of the open airbag 704 can protect the equipment from damage, and the airbag 704 can absorb part of the impact force, thereby reducing the wear of the components of the compact shelving 5.

[0053] Everything in the above example works like this:

[0054] In the initial state: the compact shelving 5 is placed in the middle of the slide rail 2, and the first gear 4 is placed in the middle of the rack 3; the rotating column 603 in the reciprocating obstacle clearing mechanism 6 is in contact with the teeth at the bottom of the toothed plate 601, and the two groups of obstacle clearing plates 604 are symmetrically placed, and two groups of symmetrical moving blocks 607 and swing rods 608 are placed at the most side of the screw rod 606, the pressing plate 611 is not in contact with the documents placed on the surface of the storage rack 609 at this time, and the telescopic column 610 is in an uncompressed state; the telescopic plate 701 in the limit inflation mechanism 7 is in an uncompressed state, and the airbag 704 is in an uninflated state, and the swing limit plate 709 is in contact with the limit groove opened at the bottom of the second movable plate 707;

[0055] The following is the working process of the reciprocating obstacle clearing mechanism 6 to press and protect the files in the compact rack when the compact rack is moved:

[0056] When in use, the staff first uses the controller to rotate the screw rod 606 fixedly connected to the output shaft end of the external motor. When the screw rod 606 rotates, it will drive the first gear 4 and the second gear 602 fixedly connected to its surface to rotate. When the first gear 4 and the second gear 602 rotate, the rack 3 meshing at the bottom will move, so that the compact shelf 5 moves, and the work of moving the compact shelf 5 is realized; please refer to the following working process Figure 4 , because the threads on the left and right sides of the screw rod 606 are set in opposite directions, when the screw rod 606 rotates, it will drive the two groups of threaded moving blocks 607 to approach each other. When the moving blocks 607 approach each other, they will drive the two groups of swing rods 608 symmetrically connected by pin shafts to swing, so that the telescopic column 610 slides upward on the inner wall of the sliding groove 612 opened inside the dense shelf 5. When the telescopic column 610 slides upward on the inner wall of the sliding groove 612 opened inside the dense shelf 5, it will drive the pressing plate 611 fixedly connected to its surface to move upward, so that the documents on the surface of the storage rack 609 are in contact with the pressing plate 611, so that the documents are pressed, preventing the documents from being scattered or damaged when the dense shelf 5 is moved, which can help the staff to complete the document sorting work more easily and reduce the workload;

[0057] The following is the working process of clearing obstacles in front and behind the compact shelving 5 when the compact shelving 5 is moving:

[0058] Furthermore, when the screw rod 606 rotates, it will drive the second gear 602 fixedly connected to its surface to rotate. Since the second gear 602 surface is fixedly connected with a rotating column 603, which is distributed on the surface of the second gear 602 and meshed with the teeth on the surface of the toothed pressure plate 601, when the second gear 602 rotates, it will drive the rotating column 603 fixedly connected to the surface of the second gear 602 and the meshed toothed plate 601 to make the toothed plate 601 reciprocate, so that the obstacles in front and behind the dense shelving 5 can be cleared while the dense shelving 5 is moving, preventing obstacles from appearing in front of the dense shelving 5 and affecting the movement of the dense shelving 5, and preventing the risk of the dense shelving 5 contacting with obstacles and tipping over.

[0059] The following is the working process of the limit inflation mechanism 7 to reduce the shock and protect the compact shelf 5 when the compact shelf 5 falls over:

[0060] Furthermore, when the compact shelving 5 moves left and right and tips over to the left, because the telescopic plate 701 is longer than the width of the compact shelving 5 and the telescopic plate 701 is telescopically arranged, when the compact shelving 5 tips over, the telescopic plate 701 first touches the ground, and when the telescopic plate 701 touches the ground, it slides on the top surface of the compact shelving 5, and when the telescopic plate 701 slides, it drives the wedge-shaped extrusion block 702 fixedly connected to its bottom to move toward the compact shelving 5, and when the wedge-shaped extrusion block 702 moves toward the compact shelving 5, it squeezes the wedge-shaped compression plate 703 away from the airbag 704. Slide away from one side of the second shock-absorbing column 705, so that the airbag 704 can be inflated. Because the second shock-absorbing column 705 is a spring arrangement, and there are four groups of second shock-absorbing columns 705 distributed at the four corners of the airbag 704, when the compact shelving 5 overturns, the airbag 704 can protect the compact shelving 5, and the four groups of second shock-absorbing columns 705 can reduce the shock of the compact shelving 5. When the compact shelving topples due to external force or other reasons, the shock-absorbing function can effectively reduce the speed and impact of the compact shelving toppling, thereby reducing the risk of personal injury.

[0061] The following is the working process of the limiting inflation mechanism 7 to limit the compact shelf 5:

[0062] Furthermore, when the compact shelving 5 moves on the bottom slide rail, it will drive the second movable plate 707 fixedly connected to its side to move. Because the second movable plate 707 has a slide groove on its surface and is slidably connected to the limiting sliding plate 712, and an inclined U-shaped limiting groove is provided at the bottom of the rectangular plate 711, when the second movable plate 707 moves, it will move under the limit of the limiting sliding plate 712. When the second movable plate 707 moves, it will drive the swinging plate 708 rotatably connected to it through the pin shaft to move. When the swinging plate 708 moves, it will drive the swinging plate 708 connected to it through the pin shaft to move. The swing limit plate 709 connected to the axis moves, because both ends of the swing limit plate 709 are rotatably connected to the sliding column 710 through the pin shaft, and the rectangular plate 711 is also provided with an inclined U-shaped slide groove, so when the slide column 710 moves, the U-shaped slide groove provided on the rectangular plate 711 will limit the sliding column 710, thereby limiting the swing plate 708. While limiting the swing plate 708, the dense rack 5 can also be limited when moving. Through this limiting function, it can be ensured that the dense rack can avoid safety hazards caused by excessive movement during the movement, such as tipping and sliding;

[0063] Summary: Through the setting of the reciprocating obstacle clearing mechanism 6, when the screw rod 606 rotates, it will drive the two groups of threaded moving blocks 607 to approach each other. When the moving blocks 607 approach each other, they will drive the two groups of swing rods 608 symmetrically connected by the pin shaft to swing, so that the documents on the surface of the storage rack 609 can be pressed to prevent the documents from falling or being damaged when the compact shelf 5 is moved, which will affect the subsequent use. When the screw rod 606 rotates, it will drive the second gear 602 fixedly connected to its surface to rotate. When the second gear 602 rotates, it will drive the rotating column 603 fixedly connected to the surface of the second gear 602 to mesh with the toothed plate 601 so that the toothed plate 601 performs reciprocating motion, thereby being able to clear obstacles in front and behind the compact shelving 5 while the compact shelving 5 is moving, preventing obstacles from appearing in front of the compact shelving 5 and affecting the movement of the compact shelving 5, and also preventing the risk of the compact shelving 5 tipping over due to contact with obstacles. Furthermore, when the sliding column 710 moves, the U-shaped slide groove provided on the rectangular plate 711 will limit the sliding column 710, thereby limiting the swing plate 708. While limiting the swing plate 708, the compact shelving 5 can also be limited when it moves. This limiting function can ensure that the compact shelving can avoid safety hazards caused by excessive movement during movement, such as tipping over and sliding.
