[0029] The following will be combined Figure 1-Figure 3 , a manual mattress lifter involved in the embodiment of the present application is described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0030] Embodiment 1:

[0031] like Figure 1As shown, a manual mattress lifter includes: a positioning plate 11, a support rod 1, a first connecting unit, a second connecting unit, a first driving unit, and a second driving unit. The two positioning plates 11 are used to be arranged on both sides of the bed frame; the positioning plates 11 are provided with multiple groups of waist-shaped holes for installation, which are used to connect and install the positioning plates 11 to both sides of the bed frame.

[0032] The two support rods 1 are respectively arranged above the two positioning plates 11 for placing the mattress; the support rods 1 are provided with a plurality of waist-shaped mounting holes, which can be used to mount the mattress board, and the mattress is placed on the mattress board.

[0033] The two sets of the first connection units are used to be rotatably connected to the support rod 1 and the positioning plate 11 respectively; the first connection unit is a first connection rod 2, the top end of the first connection rod 2 is rotatably connected to the support rod 1, and the bottom end of the first connection rod 2 is rotatably connected to the positioning plate 11. The first connection rod 2 can be set to be inclined, and the inclined setting here means that when the support rod 1 is roughly parallel to the positioning plate 11, the first connection rod 2 is in an inclined state, see Figure 1 .

[0034] The two sets of the second connection units are respectively used to be rotatably connected to the support rod 1 and the positioning plate 11; the second connection unit includes a first connection piece 10, a second connection piece 7 and a third connection piece 13, the bottom of the first connection piece 10 is rotatably connected to the positioning plate 11, the first connection piece 10 has a connection bottom 9 and a connection arm 8, the connection bottom 9 and the connection arm 8 form a structure similar to an obtuse triangle, the reason why the bottom of the first connection piece 10 is provided with a connection part is that sufficient connection space should be reserved at the bottom of the first connection piece 10, and the connection arm 8 is also in an inclined state when the support rod 1 is roughly parallel to the positioning plate 11, see Figure 1 .

[0035] The top of the second connecting piece 7 is rotatably connected to the support rod 1, and the top of the first connecting piece 10 is rotatably connected to the position between the middle and the right end of the second connecting piece 7; the bottom of the third connecting piece is rotatably connected to the positioning plate 11, and the top of the third connecting piece is rotatably connected to the second connecting piece 7, and a limiting slide groove 4 is provided on the third connecting piece, and a limiting column is provided on the first connecting piece 10, and the limiting column is arranged in the limiting slide groove 4. The second driving unit is a second gas spring 5, the length of the second gas spring 5 is shorter than that of the first gas spring 3, the second gas spring 5 is arranged on the other side of the first connecting unit, and the bottom of the second gas spring 5 is rotatably arranged at the bottom of the first connecting piece 10, and the top of the second gas spring 5 is rotatably arranged at the right end of the second connecting piece 7.

[0036] The third connecting piece and the limiting column on the first connecting piece 10 are provided to ensure that when the support rod 1 and the positioning plate 11 move to a substantially horizontal position under the action of the second gas spring 5, they can stop moving instead of continuing to move.

[0037] The two sets of the first driving units are used to be rotatably connected to the support rod 1 and the positioning plate 11, and the first driving unit is used to drive one end of the support rod 1 to rise or fall; the first driving unit is a first gas spring 3, the first gas spring 3 is arranged on one side of the first connecting unit, and the bottom of the first gas spring 3 is rotatably set at the bottom of the positioning plate 11, and the top of the first gas spring 3 is rotatably set on the support rod 1.

[0038] The two sets of the second driving units are used to be rotatably connected to the support rod 1 and the positioning plate 11, and the second driving unit is used to drive the other end of the support rod 1 to rise or fall.

[0039] In some embodiments, the first pull rod 6 and the second pull rod 12 are further included, wherein the two ends of the first pull rod 6 are rotatably connected to the second connecting pieces 7 on both sides, and the two ends of the second pull rod 12 are rotatably connected to the first connecting rods 2 on both sides.

[0040] The first pull rod 6 and the second pull rod 12 can ensure the lifting of both sides to be as synchronous as possible, which plays a good stabilizing role.

[0041] The present application is roughly divided into two stages when working. In the first stage, when the mattress needs to be inflated, the mattress plate is pulled upward, the mattress plate drives the support rod to move, the support rod drives the first gas spring to work, and the first gas spring lifts the support rod to an inclined state. For details, see Figure 2 The second stage is to continue to drag the mattress board backwards. At this time, the second gas spring starts to work. The second gas spring supports the second connecting piece to move upward, driving the support rod to move backward as a whole until the limiting column of the first connecting piece moves to the end of the limiting slide groove. At this time, the support rod is roughly parallel to the positioning plate, and the horizontal angle between the two is about 2°. See details. Figure 3 .

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
