In this embodiment, when the bed leg is assembled, the compression spring 3 surrounds the outer side of the upper bed leg guide 12, one end of the spring contacts with the upper bed leg guide 11, and the other end contacts with the upper surface of the first lower bed leg guide 41; the upper bed leg guide pipe 12 is arranged at the center of the lower bed leg guide sheet, and the upper bed leg is limited by a stop screw at the bottom; and finally, installing the bed foot pad 5, wherein the inner shaft diameter of the bed foot pad 5 is larger than the outer diameter of the bottom of the early warning force adjusting device 6. When the load weight above the bed approaches the limit of the variable performance of the compression spring 3, the bottom of the early warning force adjusting device 6 is contacted with the bed foot pad 5, and the part exceeding the spring force is born by the early warning force adjusting device 6, the bed foot pad 5 and the upper bed foot guide pipe 12. When the load is smaller than the spring force, the spring gradually returns to the length until the two forces balance or the early warning force adjusting device 6 is in contact with the second lower foot guide piece 42.
Further, when the compression spring is in a relaxed state, the lower edge of the upper foot section is above the first lower foot guide. In this embodiment, the upper foot section and the lower foot section may have more adjustment distances for the early warning force adjustment device under the condition that the bed body does not apply pressure or has smaller pressure, so as to adapt to more electric bed bodies.
Further, when the compression spring is at a pressure limit, the lower edge of the upper foot section is between the first lower foot guide and the second foot guide. In this embodiment, even the pressure that compression spring received makes the bed foot reach the limit, the bed foot still can keep certain height, avoids highly excessive compression with the bed foot, leads to the bed foot of whole bed to be too short, influences the bed body pleasing to the eye.
Further, the compression spring material is a high-strength spring, and preferably steel or copper. In this embodiment, the compression force of the bed leg compression spring has a high requirement, so that the stable adjusting capability can be maintained under the condition of receiving the weight of different bed bodies, the corresponding pressure is borne, the excessive change of the bed leg can be prevented, and the attractive appearance of the bed body is maintained.
Further, friction bushings 44 are provided at the inner edges of the first through holes 43 of the first and second lower foot guides 41 and 42. In this embodiment, the friction sleeve is sleeved on the inner wall of the through hole of the lower foot guide piece, and because the upper foot guide tube 12 continuously moves back and forth between the first lower foot guide piece 41 and the second lower foot guide piece 42, the friction force between the outer tube wall of the upper foot guide tube 12 and the lower foot section 4 can be effectively reduced, and the better damping effect is maintained.
Further, the bottom of the bed foot pad 5 is made of elastic material, and a cavity structure with an upper opening and a lower closed is adopted. In this embodiment, the bottom of the bed pad 5 is made of polyurethane material, and the upper opening is used for bearing the early warning force adjusting device 6, compared with the prior art, the general bed pad 5 adopts elastic material at the part contacting with the ground to play a role in shock absorption, but the utility model also adopts elastic material in the pad, when the weight of the bed body exceeds the early warning force of the compression spring 3, the bottom of the early warning force adjusting device 6 is elastically contacted with the inside of the bed pad 5, so as to realize better shock absorption effect.
Further, the early warning force adjusting device 6 includes an internal threaded female member 61 embedded in the lower leg section 4 and a rotating sub-member 62, the internal threaded female member 61 is provided with a second threaded hole 63 downward, the inner wall is provided with threads, the rotating sub-member 62 includes a rod portion 621 matching with the internal threaded female member 61, the end portion of the rod portion 621 is provided with a panel portion 622, and the panel portion 622 can move up and down relative to the bottom of the second lower leg guide piece 42. In this example, the panel 622 and the rod 621 are "T" shaped, and the outer diameter of the panel 622 is equal to or smaller than the inner diameter of the inner cavity of the footpad 5. As shown in fig. 3 and 4, the working principle of the early warning force adjusting device 6 is as follows: dividing the weight of the bedstead, the bed board, the mattress and corresponding accessories in the bed body by the number of the shock absorption bed legs to obtain the early warning pressure of each shock absorption bed leg, and calculating whether the shock absorption bed leg can bear the distributed pressure by combining the deformation force of the compression spring 3; as shown in fig. 3, in the initial state: f spring (early warning force) =f early warning force adjusting device 6, at this time, both internal forces are balanced. When the bed leg is pressed: when F pressure is smaller than F spring (early warning force), F limit screw can be reduced along with the increase of F pressure, at this time, the spring has no obvious deformation, and the upper bed leg section 1 has no relative displacement relative to the lower bed leg section 4. When the F pressure is larger than the F spring (early warning force), after the compression spring 3 is compressed to the lowest position, the F early warning force adjusting device 6 downwards touches the bed foot pad 5 to be propped against; the balance of the two forces is achieved, and the damping effect is generated. In the initial state, the female screw member 61 and the rotary sub-member 62 are screwed with each other, but a certain distance is left in the interior, and the female screw member and the rotary sub-member are not propped up; when F pressure is greater than F spring (early warning force), the rotary sub-piece 62 can be continuously screwed upwards into the internal thread female piece 61 until the internal thread female piece is dead, so that the upper bed leg section 1 can travel a longer distance relative to the lower bed leg section 4 by adjusting, adapt to heavier bed body weight, and then abut against the inner wall of the bed foot pad 5, and different damping effects are realized.
Further, the height of the foot pad 5 is greater than the distance the rotating sub-assembly can move relative to the female threaded sub-assembly. In this embodiment, the damping effect depends on the contact between the adjusting distance of the early warning force adjusting device 6 and the foot pad, and the height of the foot pad 5 is greater than the displacement distance of the rotating sub-component, so that the function of the early warning force adjusting device 6 can be fully exerted, and a better damping effect is achieved.
Further, a foot screw 45 is provided at the top of the upper foot guide tube 12. In this embodiment, the portion of the upper foot guide tube 12 extending out of the upper foot guide plate 11 is provided with a foot screw portion 45 for rotating connection with the foot.
Further, rectangular holes 13 are formed in the outer walls above and below the upper foot guide tube, and are used for welding the embedded early warning force adjusting device 6 and the foot screw portion 45. In this embodiment, when the upper foot section is assembled, the foot screw 45, the early warning force adjusting device 6 and the upper foot conduit need to be assembled, and the welding point is a rectangular window at the foot conduit as shown in fig. 5. After welding, the surface of the round tube is required to be polished, so that the cylindricity of the round tube is ensured.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
