DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] like Figure 1-Figure 7 As shown, a top-spring structure proposed in an embodiment of the present application comprises: a storage box 1, the top of which is open, the storage box 1 is arranged on one side of the aviation chair, a movable plate 2 is slidably arranged in the storage box 1; the movable plate 2 adopts a horizontal plate, which is vertically slidably arranged in the storage box 1, and the top of the movable plate 2 is used to install a table board, a cross bar 3 is arranged in the storage box 1, the cross bar 3 is located below the movable plate 2, and two movable blocks 4 are slidably sleeved on the cross bar 3, and the movable blocks 4 are hinged with support rods 5 on the opposite sides, and the ends of the two support rods 5 are respectively hingedly connected to the bottom of the movable plate 2 and the inner bottom wall of the storage box 1, and limit blocks 6 are arranged at both ends of the cross bar 3, and a first spring 7 sleeved on the cross bar 3 is installed between the two limit blocks 6 and the two movable blocks 4; an insertion rod 8 slides through an inner wall of one side of the storage box 1, and a socket 9 is opened at one end of the movable plate 2, and the insertion rod 8 is inserted and matched with the socket 9, as shown in FIG. Figure 2As shown, at this time, the table top is in the storage box 1 and is in a stored state, and the first spring 7 is in a compressed state. When the table top needs to be taken out, the insertion rod 8 is pulled out of the insertion hole 9. At this time, the movable plate 2 is in a released limit state, and the first spring 7 releases pressure and releases the elastic force. Under the elastic force resistance, the two movable blocks 4 slide close to each other. When the movable blocks 4 slide close, the cross bar 3 moves upward, so that the support rod 5 remains in an upright state, thereby sliding the movable plate 2 to the box opening of the storage box 1, thereby The table top is lifted out of the storage box 1. When the table top needs to be stored, first press down to drive the table top to be stored in the storage box 1, and then drive the movable plate 2 to move downward. As the movable plate 2 moves downward, the support rod 5 will contact the two movable blocks 4 to move away from each other, and make the movable block 4 squeeze the first spring 7, and then insert the insertion rod 8 into the socket 9 to fix the movable plate 2. When the table top needs to be used, it is only necessary to pull the insertion rod 8 out of the socket 9 and use the elastic force of the first spring 7 to lift it up, thereby improving the convenience during use.

[0028] like Figure 7 As shown, in some embodiments, two spring telescopic rods 10 are provided on the inner bottom wall of the storage box 1, and the two spring telescopic rods 10 correspond to two of the support rods 5 one by one, and the free ends of the spring telescopic rods 10 are rollingly inserted with balls 11. When the movable plate 2 moves downward, the two support rods 5 located below will rotate around the hinge point and respectively contact the free ends of the two spring telescopic rods 10, so that the spring telescopic rods 10 will contract. When the insertion rod 8 is pulled out of the socket 9, the spring telescopic rod 10 will reset, thereby generating an upward elastic thrust, thereby assisting the movable plate 2 to move upward, so that the movable plate 2 drives the table top to move up more smoothly. Since the support rod 5 rotates around the hinge point to contact the spring telescopic rod 10, the balls 11 are provided to reduce the friction resistance when the support rod 5 contacts the end of the spring telescopic rod 10, so that the spring telescopic rod 10 can be compressed and contracted more smoothly.

[0029] like Figure 6 As shown, in some embodiments, a slot 12 is opened on the inner wall of one side of the storage box 1, and the insertion rod 8 slides through the slot 12. A limiting plate 13 fixed on the insertion rod 8 is slidably set in the slot 12, and a second spring 14 mounted on the insertion rod 8 is installed between the limiting plate 13 and the inner wall of the slot 12. The opening of the slot 12 and the setting of the limiting plate 13 prevent the insertion rod 8 from being completely separated from the storage box 1, thereby preventing the insertion rod 8 from being lost. Since the aircraft has a certain vibration force during takeoff and landing, through the setting of the second spring 14, when the insertion rod 8 is inserted into the socket 9, the second spring 14 applies a certain elastic force to the insertion rod 8 to prevent the insertion rod 8 from being separated from the socket 9 due to the influence of vibration, thereby preventing the table top from automatically popping out.

[0030] like Figure 4 and Figure 6As shown, in some embodiments, a through slot 15 communicating with the slot 12 is provided on the top of the storage box 1, a pressing rod 16 is slidably inserted into the through slot 15, a first inclined surface is configured on the limiting plate 13, and a second inclined surface overlapped with the first inclined surface is configured at the bottom end of the pressing rod 16, as shown in FIG. Figure 4 As described, the bottom end of the pressing rod 16 is constructed with an avoidance groove, so that the insertion rod 8 will not interfere with the movement of the pressing rod 16. By setting the pressing rod 16, the top end of the pressing rod 16 is located at the top of the storage box 1. The pressing rod 16 is pressed, and the interference between the first inclined surface and the second inclined surface is utilized to drive the limit plate 13 to move, thereby driving the insertion rod 8 to move, thereby realizing fixing and releasing, making adjustment more convenient.

[0031] like Figure 4 and Figure 6 As shown, in some embodiments, the socket 9 is constructed as a tapered hole, and the end of the insertion rod 8 is provided with a tapered block 17 that is plugged into the tapered hole. By constructing the socket 9 as a tapered hole and providing the tapered block 17 at the end of the insertion rod 8, and utilizing the structure of the tapered surface of the tapered block 17, when fixing the movable plate 2, it is only necessary to press the table top to drive the movable plate 2 to move downward, so that the insertion rod 8 can be automatically driven to move for self-locking, and there is no need to manually adjust the pressing rod 16 or the insertion rod 8, thereby improving convenience.

[0032] like Figure 2 and Figure 3 As shown, a table top proposed in one embodiment of the present application also includes a storage board 18, one end of which is hingedly connected to the top of the movable board 2, and the storage board 18 is used to place items. When the storage board 18 remains in an upright state, it can be stored in the storage box 1. When the movable board 2 moves up to the box opening of the storage box 1, the storage board 18 is rotated around the hinge point so that it overlaps the box opening of the storage box 1, which can ensure that the table top is in a horizontal and flat state.

[0033] like Figure 3 As shown, in some embodiments, the storage board 18 includes a first plate body 1801 and a second plate body 1802 that are hingedly connected. The first plate body 1801 is hingedly connected to the movable plate 2. A card slot 1803 is provided on the first plate body 1801, and a card plate 1804 that is engaged with the card slot 1803 is provided on the second plate body 1802. By dividing the storage board 18 into the first plate body 1801 and the second plate body 1802 that are hingedly connected, the two can be folded around the hinge point for easy storage. At the same time, when the two are unfolded, the placement area can be expanded. When the two are unfolded, the card plate 1804 is clamped in the card slot 1803, so that the first plate body 1801 and the second plate body 1802 are in a horizontal state, which is convenient for effective placement of items.

[0034] like Figure 1 and Figure 3As shown, in some embodiments, a cover 19 is hinged on one side of the top of the storage box 1 through a hinge. The cover 19 arranged by the hinge has two advantages. First, when the storage board 18 is placed in the storage box 1, the cover 19 can be buckled around the hinge point to fit the box opening of the storage box 1. At the same time, the pressing rod 16 is hidden to prevent the pressing rod 16 from being accidentally touched by the arm. Second, when the storage board 18 needs to be used, the cover 19 is first rotated around the hinge point to open it. The port of the cover 19 is flush with the box opening of the storage box 1. When the storage board 18 is rotated around the hinge point to a flat state, the storage board 18 is overlapped on the cover 19. The cover 19 can support the storage board 18. The cover 19 can serve as an extension of the overlapping surface of the box opening of the storage box 1 to ensure that the storage board 18 is more stable after being laid flat.
