Detailed implementation mode

[0027] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0028] The foldable mobile shelf according to the embodiment of the present application will be described below with reference to the drawings.

[0029] The foldable mobile shelf provided by the embodiment of the present application can be applied to places such as warehouses and flat yards on the ground.

[0030] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the foldable mobile shelf according to the embodiment of the present application includes a support mechanism 100, a loading mechanism 200 and a moving device 112.

[0031] The loading mechanism 200 is used for placing goods. The loading mechanism 200 includes multiple groups of trusses 210 and multiple groups of cross bars 220. The multiple groups of trusses 210 and the multiple groups of cross bars 220 are respectively installed on the support mechanism 100.

[0032] The support mechanism 100 is used for supporting the loading mechanism 200. The support mechanism 100 includes a fixed vertical frame 110, a moving vertical frame 120 and a support vertical frame 130. Among them, two groups of fixed vertical frames 110 are provided. Multiple groups of trusses 210 are arranged between the two groups of fixed vertical frames 110. The two ends of one side of the multiple groups of trusses 210 are respectively pivotally connected to the fixed vertical frame 110; two groups of moving vertical frames 120 are provided. The two groups of moving vertical frames 120 are pivotally connected to the multiple groups of trusses 210, and the two groups of moving vertical frames 120 are located at the two ends of the other side of the multiple groups of trusses 210 away from the fixed vertical frame 110; the support vertical frame 130 is movably connected to the moving vertical frame 120, and the moving vertical frame 120 can slide along the support vertical frame 130.

[0033] The mobile device 112 is disposed at the bottom ends of the fixed vertical frame 110 and the support vertical frame 130. The mobile device 112 is used to drive the support mechanism 100 or a part of the support mechanism 100 to move.

[0034] The foldable mobile rack according to the embodiment of the present application can be folded and changed from the form as Figure 2 shown to the form as Figure 4 shown. When arranging the racks in the warehouse, the distance between the racks can be reduced, and the reserved space required for mechanical equipment can be reduced. Moreover, after folding, the foldable mobile rack can be conveniently moved and occupies a small space, which can save a large amount of reserved space for the warehouse, thereby improving the storage density and utilization rate of the warehouse and being beneficial to reducing the warehousing cost of the enterprise.

[0035] Specifically, the truss 210 pivotally connected to the fixed vertical frame 110 described in this embodiment can rotate around the axis formed by the connection position of one side of it and the fixed vertical frame 110. When the truss 210 rotates, the other side of the truss 210 gradually approaches the fixed vertical frame 110. The movable vertical frame 120 pivotally connected to the other side of the truss 210 also rotates and approaches the fixed vertical frame 110 and moves downward along with the truss 210, and always maintains a parallel relationship with the fixed vertical frame 110. When the movable vertical frame 120 moves downward, it drives the support vertical frame 130 to approach the fixed vertical frame 110 at the same time, and the movable vertical frame 120 moves downward on the support vertical frame 130.

[0036] It should be noted that for the foldable mobile rack of this embodiment, when in the unfolded form, as Figure 2 shown, the movable vertical frame 120 is located directly above the support vertical frame 130. When folding is required, relevant professionals can pull the support vertical frame 130 outward to the lower side of the movable vertical frame 120, and then push the movable vertical frame 120 to move in the direction of and downward toward the fixed vertical frame 110 until it is in the state as Figure 4 shown.

[0037] As a possible situation, cross bars 220 are connected between adjacent two groups of fixed vertical frames 110 and between adjacent two groups of support vertical frames 130 to make the connection between adjacent two groups of fixed vertical frames 110 and between adjacent two groups of support vertical frames 130 more stable.

[0038] As another possible situation, as Figure 1 shown, mobile devices 112 are respectively disposed at the bottoms of the movable vertical frame 120 and the support vertical frame 130 for moving the foldable mobile rack when it is empty or has a small amount of goods placed on it. Specifically, the mobile device can adopt universal wheels, heavy object movers, etc.

[0039] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 1 and Figure 3As shown, a hinge seat 111 is provided on the fixed vertical frame 110, a hinge hole is provided on the movable vertical frame 120, hinge rods 211 are respectively provided at positions near the corners on the truss 210, and the hinge rods 211 are respectively inserted into the hinge seat 111 and the hinge hole.

[0040] Specifically, at both ends of the side of the truss 210 connected to the fixed vertical frame 110 described in this embodiment, protruding hinge rods 211 are respectively provided. The hinge rods 211 are inserted into the hinge seats 111 provided on the side surface of the fixed vertical frame 110, and the width between the two groups of fixed vertical frames 110 is greater than the width of the truss 210 in the same direction. Similarly, at both ends of the side of the truss 210 connected to the movable vertical frame 120, protruding hinge rods 211 are respectively provided. The hinge rods 211 on this side are inserted into the hinge holes provided on the movable vertical frame 120, and the width between the two groups of movable vertical frames 120 is greater than the width of the truss 210 in the same direction.

[0041] As a possible situation, the distance between the two groups of fixed vertical frames 110 described in this embodiment is the same as the distance between the two groups of movable vertical frames 120, and is greater than the width of the truss 210 in the same direction. This is beneficial for the truss 210 to rotate around the connecting line axis of the hinge seats 111 and / or the connecting line axis of the hinge holes, and to avoid bumping or hindering during the rotation process.

[0042] It can be understood that the connecting line axis of the above hinge seats 111 is the connecting line between the two groups of hinge seats 111 connected to the two sides of the truss 210. The same applies to the connecting line axis of the hinge holes, so it will not be elaborated.

[0043] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 2 、 Figure 4 and Figure 5 shown, at one end of the movable vertical frame 120 connected to the support vertical frame 130 described in this embodiment, a limit hanger 121 is provided. One end of the limit hanger 121 is pivotally connected to the movable vertical frame 120, and the other end of the limit hanger 121 is slidably connected to the support vertical frame 130. Among them, a lifting limit groove 131 is provided on the support vertical frame 130, and the other end of the limit hanger 121 is slidably installed in the lifting limit groove 131.

[0044] Specifically, one end of the limit hanger 121 is hinged to the outside of the movable vertical frame 120, and the other end can be slidably clamped in the lifting limit groove 131 through a connecting rod extending inward, which can connect the movable vertical frame 120 and the support vertical frame 130 together and prevent the two from separating from each other.

[0045] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 1 and Figure 3As shown in the figure, multiple groups of fixed vertical frames 110, movable vertical frames 120, and supporting vertical frames 130 are respectively provided. Multiple groups of trusses 210 can be provided between multiple groups of fixed vertical frames 110 and movable vertical frames 120, and multiple groups of crossbars 220 can be provided between multiple groups of fixed vertical frames 110 and between multiple groups of supporting vertical frames 130.

[0046] Specifically, multiple groups of fixed vertical frames 110 can be provided longitudinally. Trusses 210 can be provided between two adjacent groups, and movable vertical frames 120 and supporting vertical frames 130 are provided in cooperation. Multiple groups (in a column) of trusses 210 can be provided vertically and connected between the fixed vertical frames 110 and the movable vertical frames 120. Crossbars 220 are connected between two adjacent groups of fixed vertical frames 110 and between two adjacent groups of supporting vertical frames 130.

[0047] For example, as Figure 1 shown, two groups (in a column) of trusses 210 are provided between two groups of fixed vertical frames 110 and two groups of movable vertical frames 120 vertically. Two groups of crossbars 220 are provided between two groups of fixed vertical frames 110, and two groups of crossbars 220 are provided between two groups of supporting vertical frames 130. Among them, the crossbar 220 at the bottom between two groups of fixed vertical frames 110 has the same height as the crossbar 220 between the bottoms of the supporting vertical frames 130. As Figure 3 shown, two columns of trusses 210 are provided for three groups of fixed vertical frames 110 longitudinally, and three groups of movable vertical frames 120 and three groups of supporting vertical frames 130 are provided in cooperation.

[0048] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 6 shown, the supporting vertical frame 130 is a hollow structure. A lifting mechanism is provided in the hollow part of the supporting vertical frame 130. The lifting mechanism includes a lifting support block 132, a lifting driving wheel, and a lifting driving chain. Among them, two groups of lifting driving wheels are provided, and the two groups of lifting driving wheels are respectively provided at positions near both ends of the supporting vertical frame 130; a lifting driving chain is provided on the two groups of lifting driving wheels; a lifting support block 132 is provided on the lifting driving chain, and the lifting support block 132 is used to support the movable vertical frame 120 to enable the movable vertical frame 120 to perform a lifting movement.

[0049] It should be noted that the lifting driving wheel can rotate. When rotating, it drives the lifting driving chain, and the lifting support block 132 on the lifting driving chain can move up and down with the movement of the lifting driving chain, so as to realize supporting the movable vertical frame 120 to perform a lifting movement.

[0050] Specifically, the moving device at the bottom of the supporting vertical frame described in this embodiment is a supporting moving wheel; the lifting mechanism further includes a steering wheel 134. Among them, the supporting moving wheel 133 is arranged at the bottom of the supporting vertical frame 130. While the supporting moving wheel 133 supports the supporting vertical frame 130, it can reduce the friction force of the supporting vertical frame 130 during movement; the steering wheel 134 cooperates with the supporting moving wheel 133 and a lifting driving wheel respectively for commutation and transmission.

[0051] It should be noted that during specific use, relevant professionals can push / pull the supporting vertical frame 130 to move, drive the supporting moving wheel 133 to rotate, and then drive the lifting driving wheel to lift through the steering wheel 134, so as to drive the moving vertical frame 120 to perform a lifting movement through the lifting support block 132. Among them, when pushing or pulling the supporting vertical frame 130, it can be carried out by means of other mechanical equipment, such as a forklift, etc. In addition, tools such as a storm machine and a hand-held electric drill can also be used to drive the lifting driving wheel to rotate, and then drive the supporting moving wheel 133 to rotate through the steering wheel 134, so as to move the supporting vertical frame 130 with less manpower, thereby completing the folding or unfolding action of the foldable mobile shelf.

[0052] As a possible situation, a positioning groove 122 is arranged at the bottom position of the moving vertical frame 120, and the positioning groove 122 cooperates with the lifting support block 132. When the lifting support block 132 drags the moving vertical frame 120, a part of the lifting support block 132 is stuck in the positioning groove 122, which can avoid dislocation. In addition, as Figure 6 shown, when the lifting support block 132 moves to a position close to the top of the lifting drive chain, the lifting support block 132 will rotate around the center of the lifting drive wheel. The rotating lifting support block 132 can push the moving vertical frame 120 on one side of the supporting vertical frame 130 to directly above the supporting vertical frame 130, thereby completing the unfolding action of the foldable mobile shelf. Similarly, when the foldable mobile shelf is folded, the lifting support block 132 can push the moving vertical frame 120 from directly above the supporting vertical frame 130 to the side above the supporting vertical frame 130 through the positioning groove 122 and guide it to descend.

[0053] As another possible situation, as Figure 6 and Figure 7 shown, a plurality of limit card slots are arranged on the supporting vertical frame 130 described in this embodiment, and a support block limit card 1321 is arranged on the lifting support block 132. When needed, the support block limit card 1321 is clamped in the limit card slot to limit the movement of the lifting support block 132 on the supporting vertical frame 130, and avoid the uncontrolled descent of the lifting support block 132 when holding the moving vertical frame 120. To improve the use safety of the embodiment of the present application.

[0054] In summary, the foldable mobile shelf provided by the embodiment of the present application can be composed of, such asFigure 2 The shown form folds and changes to the form as Figure 4 shown. When arranging the shelves in the warehouse, the distance between the shelves can be reduced, and the reserved space required for mechanical equipment can be decreased. Moreover, after being folded, the foldable mobile shelf can be conveniently moved and occupies a small space, which can save a large amount of reserved space for the warehouse, thereby improving the storage density and utilization rate of the warehouse and being beneficial to reducing the warehousing cost of the enterprise.
