Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the utility model.

[0028] Embodiment one,

[0029] As Figs. 1-2 shown, the embodiment proposes a storage elevator, including frame body 1 capable of being installed on the ceiling and four cables 2, the frame body 1 includes two parallel, spaced apart, elongated channel members 11, rotatable shaft body 12 is arranged between the two channel members 11, the both ends of the shaft body 12 are respectively threaded through the middle part of the two channel members 11, and the both ends of the shaft body 12 are provided with concentrators 121;Each free end of each channel member 11 includes a pulley 13;Four cables 2 have one end wound on the concentrator 121, and the cable 2 has a free end extending along the channel member 11 transversely and over the corresponding pulley 13 downward;The free end of the cable 2 is used to connect the platform supported thereby;The frame body 1 is provided with a mounting seat 14, the mounting seat 14 is provided with an adjusting device 3 for controlling the rotation of the shaft body 12 to change the height of the platform, and the output end of the adjusting device 3 is connected with one end of the shaft body 12. The concentrator 121 is a spool mounted on the end of the shaft body 12.

[0030] The frame body 1 further includes attachment device 4 for fixedly attaching the frame body 1 to the horizontal ceiling;The attachment device 4 is a plurality of bolt fasteners.

[0031] The adjusting device 3 comprises a gear box 31, an outer shell 32 is connected outside the gear box 31, the gear box 31 is connected and fixed with the mounting base 14 through the outer shell 32; a linkage mechanism and an input element 33 protruding from the outer shell 32 are arranged inside the gear box 31, the output end of the linkage mechanism is connected with the shaft body 12, and the linkage mechanism can be driven to operate by driving the input element 33. The linkage mechanism comprises a worm wheel 34 and a worm 35, the worm wheel 34 is rotatably arranged at the center of the inside of the gear box 31, the worm 35 is fixedly arranged on the input element 33, and the worm 35 is engaged with the worm wheel 34. The driving mode of the input element 33 is manual driving or electric driving. The gear box 31 is as close to the ceiling as possible, and the input element 33 only extends a limited distance below the gear box 31. The linkage mechanism has a preset transmission ratio, so as to ensure that the shaft body 120 will not rotate spontaneously due to the load on the platform, and is locked in place due to the inherent friction and geometry of the linkage mechanism. It can prevent the platform from naturally descending due to the influence of heavy objects, unless the input element 33 is driven, and other mechanisms that provide similar friction locking can be replaced in alternative embodiments to provide safe operation and storage. Therefore, the goods on the platform will not be disturbed when the platform is raised, or the indoor net height is reduced.

[0032] When the input element 33 is manually driven, the operator can use an elongated rod with a hook to drive the input element 33 by hooking the ring inside the input element 33, and then drive the worm wheel 34 to rotate through the worm 35, and then drive the shaft body 12 to rotate, so as to retract or release the four cables at the same speed, so that the platform remains horizontal when it is raised or lowered.

[0033] When the input element 33 is electrically driven, the input element 33 is driven to move by a motor, and then the worm wheel 34 is driven to rotate through the worm 35, and then the shaft body 12 is driven to rotate, so as to retract or release the four cables at the same speed, so that the platform remains horizontal when it is raised or lowered.

[0034] When the storage elevator of the embodiment is under load, each cable bears most of the load, which generates downward and inward forces on the pulley. The downward force is transmitted to the ceiling through the screw and then to the hole slot of the horizontal upper part of the channel member 11. The inside load generates longitudinal compression in the solid channel member 11, the torque applied to the shaft body is limited due to the limited radius and length of the shaft body, and it is easy to be borne by the worm wheel. The cable 2 associated with the opposite channel member 11 operates in the same way, so that the platform remains horizontal under all conditions of rotation of the shaft body 12.

[0035] The embodiment overcomes the limitations of the prior art by providing a storage facility having a frame body 1 with a pair of opposing, parallel spaced apart elongate channel members 11. Each elongate channel member 11 includes attachment means 4 for attaching the frame body 1 to a horizontal ceiling. Each elongate channel member 11 has a cable support element at each end for supporting a cable. An elongate rotatable shaft body 12 is threaded through the middle of each of the channel members 11 and has a cable collector 121 at each end for collecting a storage cable. The cable collector is in the form of a spool to better match the profile of the shaft body 12 and to collect more cable. An output of adjustment means 3 is connected to the shaft body 12 to control the rotational operation of the shaft body 12. A plurality of cables 2 each have one end connected to the shaft body 12. Each cable 2 also has an intermediate portion received by a respective cable support element and a free end extending downwardly from the cable support element. A platform is connected to and supported by the free ends of the cables and is raised or lowered in response to the rotational operation of the shaft body 12 by the adjustment means 3. The embodiment can lift and lower the platform with the articles to be transported, which is not only convenient and labor-saving, but also further reduces the safety risk, and the structure is simple, which can save a large amount of production cost.
