DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(9) With reference to FIG. 1 to FIG. 5, a lifting storage device comprises multiple bodies 7 movably stacked up and down, a support frame slideway limiting plate 17 is arranged below a bottom-layer box body 7, X-shaped hinges 10 are symmetrically arranged on two sides of the box body 7 respectively, and a bottom end of the X-shaped hinge 10 is movably connected with the support frame slideway limiting plate 17. As shown in the figures, a slideway 1701 is arranged on the support frame slideway limiting plate 17, a front hinge point 1001 at a bottom end of the X-shaped hinge 10 is movably connected with the slideway 1701, and a rear hinge point 1002 at the bottom end of the X-shaped hinge 10 is fixedly connected with the support frame slideway limiting plate 17.

(10) A box body front rotating shaft 12 and a box body rear rotating shaft 11 are respectively arranged in front of and behind each box body 7 through connecting lugs, two ends of the box body front rotating shaft 12 and the box body rear rotating shaft 11 are respectively connected with the front and rear hinge points of the X-shaped hinges 10 on two sides, and a stable quadrilateral structure is formed between the front and rear rotating shafts and the X-shaped hinge. During mounting, the box body front rotating shaft 12 and the box body rear rotating shaft 11 of each box body 7 are connected with the X-shaped hinge 10 in a staggered manner, wherein the box body front rotating shaft 12 is movably connected with the lower-layer front hinge point 1001 of the X-shaped hinge 10, and the box body rear rotating shaft 11 is movably connected with the upper-layer rear hinge point 1002 of the X-shaped hinge 10, so that each box body 7 may be inclined with the lifting of the X-shaped hinge 10 after mounting. In this structural design, mounting connection of the box body front rotating shaft 12 and the box body rear rotating shaft 11 with the box body 7 and the X-shaped hinge 10 may be designed into movable connection, so as to facilitate maintenance, and more flexible and convenient replacement of the box body 7.

(11) In order to make the lifting more smooth without resistance, an oil-free bushing 23 may be mounted in a rotating shaft hole of the hinge point of the X-shaped hinge 10, and the oil-free bushing 23 is mounted in cooperation with the box body front rotating shaft 12/the box body rear rotating shaft 11, which can realize low-speed self-lubrication and reduce wear, and is more concise and durable than a bearing structure. In addition, a grooved rolling bearing 18 may also be arranged on the box body front rotating shaft 12 of the bottom-layer box body 7, a slide rail 14 is correspondingly mounted on the support frame slideway limiting plate 17, and a semi-circular bearing inner groove of the grooved rolling bearing 18 crosses over the slide rail 14 to roll back and forth, which assists the lifting of the X-shaped hinge 10, thus greatly reducing running resistance.

(12) The X-shaped hinge 10 is provided with a plurality of nitrogen springs 15 for controlling the limiting, one end of each nitrogen spring 15 is connected with a previous hinge, and the other end of each nitrogen spring is connected with a latter hinge. Due to the arrangement of the oil-free bushing, the grooved rolling bearing and other structures capable of reducing the running resistance, the exertion of the nitrogen spring can be reduced, so that a very good support effect can be achieved by a smaller nitrogen spring, thus further reducing a product cost.

(13) A locking mechanism 16 is arranged on the support frame slideway limiting plate 17 corresponding to the X-shaped hinge 10. With reference to the figures, the locking mechanism 16 is arranged in a final position of a slideway 1701 on the support frame slideway limiting plate 17 and comprises a deadbolt 1601, the deadbolt 1601 is movably connected with the support frame slideway limiting plate 17 through a rotating shaft, a torsion spring 1604 is mounted in the deadbolt 1601, one end of the torsion spring 1604 is connected with the deadbolt 1601, the other end of the torsion spring 1604 is connected with a torsion spring clamping position 1602, and a deadbolt hanging plate 1603 and a limiting catch 1605 are also provided corresponding to the deadbolt 1601.

(14) In order to ensure a lifting safety, the device may also be provided with a plurality of safety protection mechanisms. As shown in the figures, a bottom portion of the bottom-layer box body 7 is provided with an oil pressure buffer 22, an oil pressure buffer impact plate 13 is correspondingly arranged on the support frame slideway limiting plate 17, a buffer limiting seat 20 may also be mounted on the support frame slideway limiting plate 17, a rear portion of the support frame slideway limiting plate 17 is provided with a limiting guide bracket 21, and the X-shaped hinge 10 is movably abutted with the limiting guide bracket 21 correspondingly.

(15) A lifting handrail 9 is mounted on a top-layer box body 7 to facilitate pulling.

(16) An upper cover plate 1 may also be mounted above the top-layer box body 7, the box body front rotating shaft 12 and the box body rear rotating shaft 11 may also be mounted below the upper cover plate 1, and a difference lies in that the box body front rotating shaft 12 and the box body rear rotating shaft 11 are connected with the hinge points of the same layer of the X-shaped hinge 10. For convenience of use, the box body rear rotating shaft 11 is connected with the upper cover plate 1 through a connecting lug, while the box body front rotating shaft 12 is not connected with the upper cover plate 1 and is only movably abutted. The box body front rotating shaft 12 may also be provided with a rolling bearing 19 (corresponding to a mounting slide rail on the upper cover plate 1) to assist smooth running, and after such mounting, the box body front rotating shaft 12 and the box body rear rotating shaft 11 may support the upper cover plate 1 during lifting. The upper cover plate 1 is always in a horizontal state and is lifted along with the X-shaped hinge 10, and meanwhile, a front portion of the upper cover plate 1 is not fixed, so that the upper cover plate may be opened upwardly at will.

(17) A working principle is briefly described as follows.

(18) The hand-held lifting handrail 9 is pulled upwardly, and the X-shaped hinge 10 is unfolded upwardly to be lifted, thus driving the plurality of movable box bodies 7 to be lifted. After being lifted, each box body 7 is supported by the box body front rotating shaft 12 and the box body rear rotating shaft 11 to be inclined from rear to front, adjacent box bodies 7 are separated along with each layer of hinges, and an interior of the box body is fully displayed, thus being used as an exhibition board to display articles.

(19) When lifted to a predetermined height, the box body is clamped and fixed through the locking mechanism 16. As shown in the figures, due to an action of the torsion spring 1604, the deadbolt 1601 always keeps in an ordinary state that a tail portion is tilted upwardly. In order to prevent the deadbolt 1601 from being excessively and continuously rotated under a spring force of the torsion spring 1604, the limiting catch 1605 is arranged at a head portion of the deadbolt 1601 for stopping. When the X-shaped hinge 10 is pulled upwardly, the box body front rotating shaft 12 of the bottom-layer box body 7 slides along the slideway 1701, the tilted deadbolt 1601 is pressed down first to reach the final position of the slideway 1701, then the box body front rotating shaft 12 no longer presses the deadbolt 1601, the deadbolt 1601 is tilted upwardly again under the action of the torsion spring 1604, and the box body front rotating shaft 12 is clamped at an edge of the slideway 1701 to be fixed.

(20) When the box body 7 needs to be lowered, the deadbolt 1601 is manually rotated and pressed down, the deadbolt 1601 is hung on a hook of the deadbolt hanging plate 1603, then the deadbolt 1601 is no longer tilted to block the box body front rotating shaft 12, the box body front rotating shaft 12 may slide back along the slideway 1701, and the X-shaped hinge 10 is lowered to restore a horizontally stacked state of the box body 7.

(21) When the X-shaped hinges and the plurality of box bodies are lowered, in addition to damping and buffering functions of the nitrogen spring 15, the oil pressure buffer 22, the oil pressure buffer impact plate 13, the buffer limiting seat 20 and the limiting guide bracket 21 may all play a safety protection role. Before the box body is lowered to be closed, the oil pressure buffer 22 is used to impact the oil pressure buffer impact plate 13, and the oil pressure buffer 22 may well buffer and absorb kinetic energy generated by lowering, thus reducing a degree of accidental injury. The buffer limiting seat 20 is used for buffering an impact force when the X-shaped hinges and the plurality of box bodies are lowered, thus reducing impact noise and playing a buffer protection role. Meanwhile, the buffer limiting seat 20 may also be provided with an adjusting screw, and a stacking height of the folded box bodies may be controlled through the adjusting screw, thus achieving an effect of fine height adjustment. A function of the limiting guide bracket 21 is to further limit left-right deflection of a hinge mechanism after folding, so that a structural state is stable, a position after folding is accurate, and a lowering process is ensured to be safe without interference.

(22) The lifting storage device of the present invention may be used separately or in combination with a tool car or a box body, as shown in FIG. 6 and FIG. 7.
