DETAILED DESCRIPTION
[0048] The following is combined with Figure 1-7 This application is described in further detail.
[0049] The embodiment of the present application discloses a support member, which is applied to a folding bed.
[0050] Embodiment 1
[0051] See also Figure 1 and Figure 2The support member includes a support plate 1 and a connecting shaft 2. The support plate 1 is a cuboid structure, and the support plate 1 is supported by a material with elastic deformation, such as stainless steel. Connecting plates 14 are fixedly connected to the side walls on both sides of the length direction of the support plate 1, and the connecting plates 14 and the support plate 1 are perpendicular to each other. The connecting plates 14 extend along the length direction of the support plate 1, and the two connecting plates 14 are parallel to each other. A connecting hole is formed on the support plate 1, and the connecting hole is located near the side wall of one side of the width direction of the support plate 1. The connecting shaft 2 is rotatably connected to the connecting hole, and one end of the connecting shaft 2 is fixedly connected to a connecting block, and the end of the connecting shaft 2 away from the connecting block is rotatably connected to a carrier, so that the support plate 1 is rotatably connected to the carrier, and at the same time, the connecting block limits the support plate 1 from being separated from the connecting shaft 2, and at this time, the baffle abuts against the carrier, and there is a distance between the support plate 1 and the carrier.
[0052] The support member also includes a rotating shaft 3, and a receiving hole 12 is formed on the supporting plate 1. The receiving hole 12 is located on the supporting plate 1 away from the connecting shaft 2 and close to the side wall in the width direction. The rotating shaft 3 is slidably penetrated in the receiving hole 12. The rotating shaft 3 includes a column 31, a limiting ring 32 and a limiting block 33. The column 31 slides in the receiving hole 12. The limiting block 33 is a round block structure with a diameter larger than the diameter of the column 31. The limiting block 33 is fixed at the end of the column 31, and the supporting plate 1 is located between the limiting block 33 and the connecting block. A section of the column 31 away from the limiting block 33 is rotatably connected to another carrier. The limiting ring 32 is fixed on the outer shaft side of the column 31 and close to the end. The limiting ring 32 is fixedly connected to the limiting block 33. The receiving hole 12 is adapted to the limiting ring 32 so that the limiting ring 32 can be accommodated in the receiving hole 12. A guide ring 34 is fixedly connected to the outer peripheral side of the column 31. The guide ring 34 is fixed to the side of the limiting ring 32 away from the limiting block 33. The guide ring 34 is inclined to form a connecting guide surface 341, and the guide surface 341 connects the limiting ring 32 and the column 31. When in use, the guide surface 341 guides the support plate 1 to facilitate the limiting ring 32 to enter the receiving hole 12.
[0053] The support plate 1 is formed with a sliding hole 11 extending in the length direction. The sliding hole 11 is located between the receiving hole 12 and the connecting hole. The sliding hole 11 is connected to the receiving hole 12, and the sliding width is smaller than the diameter of the limiting ring 32. When in use, when the limiting ring 32 is in the receiving hole 12, the limiting ring 32 abuts against the peripheral hole wall of the receiving hole 12, and the limiting ring 32 is restricted from entering the sliding hole 11. At this time, the two carriers carrying the connecting shaft 2 and the rotating shaft 3 are supported by the support plate 1. The side of the support plate 1 away from the connecting shaft 2 is pressed in the direction away from the limiting block 33, so that the support plate 1 is bent. At this time, the rotating shaft 3 slides in the receiving hole 12 until the limiting ring 32 is separated from the receiving hole 12, and the column 31 enters the receiving hole 12. At this time, the column 31 slides in the sliding hole 11, and the two carriers for carrying the connecting shaft 2 and the rotating shaft 3 can approach each other, which can be used to form a folding structure, thereby improving the use range of the support member.
[0054] A stress hole 13 is formed on the support plate 1 . The stress hole 13 is located between the sliding hole 11 and the connecting hole. The stress hole 13 is connected to the sliding hole 11 , and the diameter of the stress hole 13 is greater than the diameter of the accommodating hole 12 .
[0055] The implementation principle of a support member in the first embodiment of the present application is:
[0056] When supporting, the limiting ring 32 is accommodated in the accommodating hole 12. At this time, the limiting ring 32 abuts against the peripheral hole wall of the accommodating hole 12, limiting the limiting ring 32 from entering the sliding hole 11, so that the support plate 1 realizes a supporting structure between the two carriers used to support the connecting shaft 2 and the rotating shaft 3.
[0057] Embodiment 2
[0058] The difference between the second embodiment of the present application and the first embodiment is that:
[0059] See also Figure 3 and Figure 4The column 31 and the rotating shaft 3 form a driving groove 37 that is interconnected. The driving groove 37 is a "convex"-shaped structure. The side with a smaller diameter of the driving groove 37 is a notch, and the notch of the driving groove 37 is located at the position of the limiting ring 32 close to the guide ring 34. There are two driving grooves 37 and they are symmetrically arranged. The extension direction of the driving groove 37 is perpendicular to the axial direction of the rotating shaft 3, and the two driving grooves 37 are interconnected. The rotating shaft 3 is provided with a limiting column 35, which corresponds to and matches the driving groove 37 one by one, and the limiting column 35 is slidably connected to the driving groove 37. The rotating shaft 3 is provided with an elastic driving member, which is a driving spring 36. The driving spring 36 is installed in the driving groove 37, and the two ends of the driving spring 36 are respectively fixed on the opposite sides of the two limiting columns 35. When the driving spring 36 is elastically released, the two limiting columns 35 are pushed to protrude out of the driving groove 37. When the support plate 1 is between the limiting column 35 and the limiting block 33, the limiting column 35 limits the support plate 1 from being away from the limiting block 33, thereby improving the stability of the support plate 1 and reducing the possibility of shaking of the support plate 1. At the same time, when the limiting ring 32 is separated from the receiving hole 12, the limiting column 35 can limit the support plate 1 from being close to the limiting block 33, thereby facilitating the support plate 1 to slide on the rotating shaft 3.
[0060] The rotating shaft 3 is provided with a control component, which includes a control rope 4 and a control column 41. The control rope 4 is located in the driving groove 37. The two ends of the control rope 4 are respectively fixedly connected to the opposite sides of the limiting column 35, and the control rope 4 is located on the side of the driving spring 36 close to the limiting block 33.
[0061] The column 31 and the limiting block 33 are respectively formed with control grooves that are interconnected. The notch of the control groove is located on the side of the limiting block 33 away from the column 31, and the control groove is connected to the driving groove 37. The control column 41 is slidably connected to the control groove. A through hole 411 is formed on the control column 41. The control rope 4 is slidably penetrated through the through hole 411. One end of the control column 41 away from the control rope 4 protrudes out of the control groove. When in use, the control column 41 is pressed to slide into the control groove. At this time, the control column 41 pulls the control rope 4, so that the control rope 4 pulls the two limiting columns 35 to completely slide into the driving groove 37, so that the limiting ring 32 can slide into or out of the receiving hole 12.
[0062] The implementation principle of a support member in the second embodiment of the present application is:
[0063] When the two carriers for carrying the connecting shaft 2 and the rotating shaft 3 need to be close to each other, first press the control column 41 to make the limiting column 35 completely slide into the driving groove 37. Then press the support plate 1 to make the limiting ring 32 disengage from the receiving hole 12, and then release the control column 41. At this time, the driving spring 36 pushes the limiting column 35 to protrude out of the driving groove 37, limiting the support plate 1, which is conducive to keeping the limiting ring 32 outside the receiving hole 12, and then the rotating shaft 3 can slide in the sliding hole 11; when the limiting ring 32 needs to slide into the receiving hole 12 so that the support plate 1 enters the supporting state, press the control column 41 again to make the limiting column 35 slide into the driving groove 37. At this time, the elastic deformation of the support plate 1 is restored, so that the limiting ring 32 slides into the receiving hole 12, and finally release the control column 41.
[0064] On the other hand, the present application discloses a folding bed, see Figure 5 and Figure 6 , including a bed frame 5 and bed legs 53. The bed frame 5 consists of a frame and bed posts 52. The bed frame 51 is a rectangular frame structure. The bed posts 52 are located in the bed frame 51 and are fixedly connected. There are multiple bed legs 53 and they are respectively hinged at the bottom of the bed posts 52. The bed legs 53 are located near the inner wall of the bed frame 51 in the length direction. There is a distance between the bed legs 53 and the inner wall of the bed frame 51. Rotation holes 54 are formed on the opposite sides of the bed legs 53 and the bed frame 51. The connecting shaft 2 is rotatably connected to the rotation hole 54 of the inner wall of the bed frame 51. The rotating shaft 3 is rotatably connected to the rotation hole 54 of the vertical side wall of the bed leg 53 close to the bed frame 51. The connecting plate 14 abuts against the inner wall of the bed frame 51.
[0065] See also Figure 6 and Figure 7 When the bed leg 53 is folded, the support plate 1 is pressed so that the limiting ring 32 is separated from the receiving hole 12, and the column 31 slides into the receiving hole 12; then the bed leg 53 is flipped toward the direction close to the bed post 52 to abut the bed leg 53, so that the column 31 slides from the receiving hole 12 into the sliding hole 11. During the flipping process of the bed leg 53, the column 31 slides along the sliding hole 11 until the bed leg 53 is flipped to abut the bed post 52. At this time, the column 31 slides to the position of the sliding hole 11 close to the stress hole 13.
[0066] When the bed legs 53 are spread out, the column 31 slides in the sliding hole 11 toward the receiving hole 12 until the column 31 slides into the receiving hole 12, and the support plate 1 elastically recovers; then, under the guidance of the guide surface 341, the limiting ring 32 slides into the receiving hole 12, and at this time, the limiting ring 32 abuts against the side hole wall of the receiving hole 12, and the support plate 1 forms a supporting structure between the bed legs 53 and the bed frame 5.
[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
