Description

Technical Field

[0001] This utility model belongs to the field of mechanical connection technology, and in particular relates to a thin-walled segmented connection structure suitable for bed bodies and an electric bed. Background Technology

[0002] To reduce the volume of the bed after folding, a segmented connection structure is often used for the bed frame. However, current segmented connection bed frames all use thick-walled tubes. Although this can improve the structural strength of the folding bed, the use of thick-walled tubes makes the overall weight of the bed heavy, making it inconvenient to move and fold, which goes against the original intention of making the folding bed easy to use. Summary of the Invention

[0003] Purpose of the utility model: In order to solve the problems existing in the prior art, this utility model proposes a thin-walled segmented connection structure suitable for bed bodies and an electric bed.

[0004] The technical solution adopted by this utility model is: a thin-walled segmented connection structure suitable for bed body, including a first fixed tube, a second fixed tube and an internal connecting tube; the first fixed tube and the second fixed tube are both hollow tubes, one end of the internal connecting tube is fixed inside the tail of the first fixed tube, and the other end is fixed inside the head of the second fixed tube, so that the tail of the first fixed tube is connected to the head of the second fixed tube.

[0005] Furthermore, it also includes a reinforcing plate, which is fixedly installed at the bottom of the internal connecting pipe, and the two are installed as a whole inside the first fixed pipe and the second fixed pipe.

[0006] Furthermore, it also includes U-shaped reinforcing ribs, which are wrapped around the connection between the first and second fixing tubes.

[0007] Furthermore, the length of the reinforcing plate is consistent with the length of the U-shaped reinforcing rib.

[0008] Furthermore, the wall thickness of the first and second fixing tubes is 1.2 mm.

[0009] This utility model also discloses an electric bed, including a bed frame, wherein the bed frame is a rectangular structure formed by fixed tubes, and the fixed tubes are a thin-walled segmented connection structure suitable for bed bodies as disclosed above.

[0010] Beneficial effects: Compared with the prior art, this utility model uses thin-walled tubes and reinforced components to ensure the strength of the bed while reducing the overall weight. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Example 1: As Figures 1 to 4 As shown, this embodiment proposes a thin-walled segmented connection structure suitable for bed frames, which mainly includes: a first fixing tube 1, a second fixing tube 2, an internal connecting tube 3, and a reinforcing plate 4. Both the first fixing tube 1 and the second fixing tube 2 are hollow tubes. One end of the internal connecting tube 3 is fixed inside the tail of the first fixing tube 1, and the other end is fixed inside the head of the second fixing tube 2. In this embodiment, both the first fixing tube 1 and the second fixing tube 2 are thin-walled fixing tubes. The wall thickness of the thin-walled fixing tubes in this embodiment is compared to the wall thickness of tubes on the market. Through the structure proposed in this embodiment, the wall thickness of the fixing tubes can be reduced, thereby reducing the weight of the bed frame. In this embodiment, the wall thickness of the first fixing tube 1 and the second fixing tube 2 is 1.2 mm.

[0015] To further strengthen the connection between the first fixing tube 1 and the second fixing tube 2, such as Figure 4 As shown, in this embodiment, a reinforcing plate 4 is added to the bottom of the internal connecting pipe 3. Figure 5 As shown, this embodiment also employs a U-shaped reinforcing rib 5, which is wrapped around the connection between the first fixing tube 1 and the second fixing tube 2.

[0016] Example 2: This example applies the thin-walled segmented connection structure for bed frames proposed in Example 1 to a sensor-assisted lifting nursing bed. The sensor-assisted lifting nursing bed mainly includes: a bed body 6 and a lifting assembly 7.

[0017] Among them, such as Figure 6 and Figure 7 As shown, the lifting assembly 7 includes: a support frame 71, a first lifting rod 72, a second lifting rod 73, a first connector 74, a first connecting rod 75, a second connector 76, and a second connecting rod 77. The ends of the first lifting rod 72 and the second lifting rod 73 are connected to the support frame 71 through the first connector 74. Specifically, the ends of the first lifting rod 72 and the second lifting rod 73 are rotatably connected to the upper end of the first connector 74, and the tail end of the first connector 74 is fixed to the support frame 71.

[0018] In this embodiment, the bed body 6 is mounted on the lifting assembly 7. A first connecting arm 61 and a second connecting arm 62 are vertically arranged at the lower end of the bed body 6. The first connecting arm 61 is rotatably connected to the upper end of the first lifting rod 72 via a first connecting rod 75. The second connecting arm 62 is rotatably connected to the upper end of the second lifting rod 73 via a first connecting rod 75 symmetrically mounted on the other side. One end of the second connecting member 76 is fixed to the first connecting rod 75, and the other end of the second connecting member 76 is rotatably connected to one end of the second connecting rod 77. The other end of the second connecting rod 77 is rotatably connected to the upper end of a third connecting member 78 fixed to a first connecting rod 75 symmetrically mounted on the other side. The lower end of the third connecting member 78 is fixed to the first connecting rod 75.

[0019] In this embodiment, with the corresponding cylinder, the bed body 6 is raised and lowered by the first lifting rod 72 and the second lifting rod 73, thereby adjusting the height of the bed body 6 for easy use.
