[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0019] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] like Figure 1-4 As shown, the Type 92 sky lifting system includes a storage rack 1 and a counterweight assembly. The top of the storage rack 1 is hinged to one end of a plurality of foldable support structures, and the other end of the support structure is hinged to a top frame 5. A support device 6 is provided on the support structure. The storage rack 1 is connected to the counterweight assembly slidably arranged on a vertical wall 13.

[0021] Specifically, the top frame 5 is arranged at the bottom of the roof, the storage rack 1 is located below the top frame 5, and the counterweight assembly is located on the vertical wall 13. In this example, the storage rack 1 is preferably a flat quadrangular prism structure with a rectangular top surface, and the support structure is preferably 4 respectively located at the four corners of the storage rack 1. The support structure can be folded / unfolded so that the storage rack can be lifted to the top frame 5 position or unfolded to the height of an ordinary table. In this example, two parallel vertically arranged slide rails 15 are preferably used, and the counterweight plate 11 can slide up and down on the slide rail 15, thereby driving the traction rope 7 to slide on the pulley block, and then controlling the up and down movement of the storage rack 1. The traction rope 7 is driven by the power device 9. The pulley block also serves as a fixed point, so there are certain requirements for the setting of the position of some pulley blocks. The top frame 5 is provided with pulley blocks at four points corresponding to the four corners of the storage rack 1. This setting makes the tension on the traction rope 7 equal to the gravity of the storage rack, and there will be no additional component force, so that the operation of the entire device is more stable.

[0022] The power device 9 can be an electric lift, a screw push rod, a counterweight manual drive, etc. For ease of operation and considering the user's own safety, this embodiment adopts an electric lift. More optimally, an intelligent control drive device can be used to access the furniture-related mobile phone application software system (wired supports RS485 protocol, wireless supports wireless communication technology, Bluetooth) for control.

[0023] In addition, the support structure includes a lower support rod 2 and an upper support rod 3 which are hinged to each other. One end of the lower support rod 2 away from the upper support rod 3 is hinged to the storage rack 1, and one end of the upper support rod 3 away from the lower support rod 2 is hinged to the top frame 5.

[0024] It should be noted that the hinge points between the lower support rod 2 and the storage rack 1, and the upper support rod 3 and the top frame 5 can only rotate within the range of 0 to 90 degrees (the lower support rod 2 and the upper support rod 3 are wedge-shaped rods, and the contact surfaces between the lower support rod 2 and the storage rack 1, and the upper support rod 3 and the top frame 5 are beveled surfaces, such as Figure 3 , 4 , so 90° is not included), the hinge point of the lower support rod 2 and the upper support rod 3 can rotate within the range of 0 to 180° (the lower support rod 2 and the upper support rod 3 are wedge-shaped, and the contact surfaces of the lower support rod 2 and the upper support rod 3 are both beveled surfaces, such as Figure 3 , 4 , so it does not include 180°), in order to save space, the lower support rod 2 and the upper support rod 3 are folded inwards, so the hinge points of the lower support rod 2 and the storage rack 1, and the upper support rod 3 and the top rack 5 should be on the inside (reference Figure 4 ), the hinge point of the lower support rod 2 and the upper support rod 3 should be on the outside (reference Figure 3 ).

[0025] In addition, the output end of the support device 6 is connected to the upper support rod 3, and the fixed end of the support device 6 is hinged to the top frame 5. The support device 6 can be a hydraulic rod, and the support device 6 will have an outward support force on the upper support rod 3 to prevent the support structure from folding by itself. The force applied by the support device 6 is always outward, that is, when the support structure is unfolded, there is a boost force on the upper support rod 3, and when it is folded, there is a resistance force on the upper support rod 3. Therefore, a greater external force is required when folding, and a counterweight component 2 is provided to offset this resistance.

[0026] like Figure 1 As shown, the counterweight assembly includes a counterweight assembly 1 and a counterweight assembly 2, the counterweight assembly 1 includes two groups of traction ropes 7 and a counterweight plate 11, one end of the two groups of traction ropes 7 is fixedly connected to the two ends of the storage rack 1, the rope body of the traction rope 7 can slide through the pulley set at the bottom of the top frame 5 and the other end is fixedly connected to the top of the counterweight plate 11, and the counterweight plate 11 can be slidably connected to the slide rail 15 vertically set on the vertical wall 13. The two groups of traction ropes 7 slide up and down synchronously to ensure that the storage rack 1 can move up and down smoothly.

[0027] The counterweight assembly 2 includes a spring 14 and a counterweight plate 10. The counterweight plate 10 includes a connection block 101 arranged at the top and sliders 102 at both sides. The connection block 101 is connected to the top of the counterweight plate 11. The slider 102 can be slidably connected to the slide rail 121. The two ends of the slide rail 121 are provided with limit blocks to limit the movement of the slider 102. The two ends of the spring 14 are respectively connected to the bottom of the counterweight plate 10 and the ground. It also includes a fixed frame 12. The two fixed frames 12 are vertically symmetrically arranged on the vertical wall 13. A counterweight assembly is arranged between the two fixed frames 12. The upper half of the two fixed frames 12 are provided with the slide rail 121. The storage rack 1 has the same mass as the counterweight plate 11. Since a supporting device 6 for applying a supporting force is provided on the upper supporting rod 3, an external force greater than the gravity of the storage rack 1 is required at the beginning to make the traction rope 7 slide upward to drive the entire device to fold, and the gravity of the counterweight component 2 itself and the tension of the spring 14 provide this external force. This external force is the starting force. When the entire device starts to fold, there is a tendency to continue to fold. Therefore, the slide rail 2 121 is only provided on the upper half of the fixed frame 12, and the counterweight component 2 will separate from the counterweight component 1 in the middle position to prevent the counterweight component from applying too much force and causing the folding speed to be too fast, causing safety problems.

[0028] In addition, the rope body of the traction rope 7 can slide through the output end of the power device 9.

[0029] Working principle: When it needs to be unfolded, the power device 9 will pull the counterweight device upward through the traction rope 7, and the shelf 1 will move downward due to its own gravity and the supporting device 6, and the entire device will unfold; when it needs to be retracted, the power device 9 drives the counterweight assembly downward, and at the same time, the counterweight assembly pulls the traction rope 7 downward through its own gravity to make the shelf 1 move upward, and the entire device folds.

[0030] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
