Description

Technical Field

[0001] This utility model relates to a bread bed component, specifically a structure that can automatically tighten the bed body. Background Technology

[0002] The bread bed is a uniquely designed type of bed furniture. Its core design concept incorporates the soft, fluffy characteristics of bread into the shape of the mattress and backrest, enhancing comfort through its fluffy bread shape and soft materials. The bread bed can be unfolded and folded up as needed. When unfolded, users can lie on it; when folded up, its volume is greatly reduced, making it easy to store.

[0003] The existing bread-shaped mattresses have an unreasonable and complex structural design for tightening the mattress frame. Because they lack a mechanism to stretch the support legs and stress rods, the rotation between these components is uncontrollable, potentially leading to accidental or excessive rotation of the stress rods. This results in poor stability between the support legs and stress rods. Furthermore, tightening the existing mattress frame is inconvenient, requiring two people for successful tightening, making for a poor user experience. Therefore, the inventor has improved the structure of the mattress frame tightening mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a structure that can automatically tighten the bed. This structure is simple in structure and reasonable in design. It not only ensures the stability of the bed in the unfolded state, but also enables the bed to be tightened smoothly, improving the user experience. It can limit the rotation angle and achieve rapid tightening of the bed. The tightening action is time-saving and labor-saving, and can be completed by a single person. It solves the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a structure that can automatically tighten the bed body, the structure including a support leg and a stress rod movably connected to the support leg, a tension spring being provided between the support leg and the stress rod, the tension spring tightening the support leg and the stress rod by extension and retraction, a first pivot point being provided on the support leg, a plurality of second pivot points being provided on the outer side of the support leg, and a third pivot point being provided at the end of the stress rod near the support leg.

[0006] Preferably, the height value of the second turning point is equal to the height value of the third turning point, and the height value of the first turning point is greater than the height value of the second turning point.

[0007] Preferably, one end of the tension spring is fixed to the stress rod at the third pivot point, and the other end is fixed to the support foot at the first pivot point.

[0008] Preferably, the stress rod is movably connected to the support foot at the second pivot point, so as to realize the flipping of the stress rod, and the flipping angle of the stress rod is between 0° and 75°.

[0009] Preferably, multiple stress rods and tension springs are provided, with multiple stress rods surrounding the outside of the support foot, and each stress rod is provided with a tension spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a structure for automatically tightening a bed frame. This structure includes support legs and stress rods movably connected to the support legs. A tension spring is installed between the support legs and the stress rods. The tension spring tightens the support legs and stress rods by extending and retracting. The overall structure is simple and rationally designed. A first pivot point is provided on the support legs, and multiple second pivot points are provided on the outer side of the support legs. A third pivot point is provided at the end of the stress rod closest to the support legs. The height values ​​of the second and third pivot points are equal, while the height value of the first pivot point is greater than that of the second pivot points. This creates a pre-tightening force in the open state of the bread bed, making it difficult to close. During the closing process, the third pivot point moves downwards, and the bed frame automatically tightens under the action of the tension spring. This ensures both the stability of the bed frame in the unfolded state and the smooth tightening of the bed frame, improving the user experience and making it suitable for widespread use.

[0011] 2. In this utility model, the stress rod is movably connected to the support foot at the second turning point, enabling the stress rod to flip. The flip angle of the stress rod is between 0° and 75°. Multiple stress rods and tension springs are provided, with multiple stress rods surrounding the outside of the support foot. Each stress rod is equipped with a tension spring. By setting multiple tension springs on one support foot, multiple stress rods can be stretched, ensuring that the structure of each part of the bread bed body flips simultaneously during the tightening process. The flip angle is limited, making the flipping of the stress rods more controllable and enabling rapid tightening of the bed body. This makes the tightening action time-saving and labor-saving, requiring only one person to operate. Attached Figure Description

[0017] Please see Figure 1 The present invention provides an embodiment of a structure that can automatically tighten the bed body. The structure includes a support leg 1 and a stress rod 2 movably connected to the support leg 1. A tension spring 3 is provided between the support leg 1 and the stress rod 2. The tension spring 3 tightens the support leg 1 and the stress rod 2 by extending and retracting. The state shown in the figure is a schematic diagram of the stress rod 2 and the tension spring 3 when the bread bed is unfolded.

[0018] Please see Figure 2 A first pivot point 11 is set on the support leg 1, and multiple second pivot points 12 are set on the outside of the support leg 1. A third pivot point 21 is set on the end of the stress rod 2 near the support leg 1. The height of the second pivot point 12 is equal to the height of the third pivot point 21, and the height of the first pivot point 11 is greater than the height of the second pivot point 12. This will give the bread bed a pre-tightening force when the bed is open, making it difficult for the bed to close. When the bed is closed, the third pivot point 21 will move downward, and the bed will automatically tighten under the action of the tension spring 3. This ensures the stability of the bed when it is unfolded and allows the bed to be tightened smoothly, improving the user experience. One end of the tension spring 3 is fixed to the stress rod 2 at the position of the third pivot point 21, and the other end is fixed to the support leg 1 at the position of the first pivot point 11.

[0019] Please see Figures 3 to 4 This is a schematic diagram of the stress rod 2 and tension spring 3 when the bread bed is tightened. At this time, the rest of the bread bed structure is retracted to the outside of the support leg 1 and only surrounds the support leg 1, greatly reducing the volume of the bread bed. The stress rod 2 is movably connected to the support leg 1 at the second turning point 12, realizing the flipping of the stress rod 2. The flipping angle of the stress rod 2 is between 0° and 75°. When the stress rod 2 flips to the attached... Figure 4 When positioned as shown, the bread bed can be tightened, making it the smallest possible bread bed.

[0020] Please see Figure 5 Multiple stress rods 2 and tension springs 3 are provided, and multiple stress rods 2 surround the outside of the support foot 1. Each stress rod 2 is provided with a tension spring 3. By stretching multiple stress rods 2, the structure of each part of the bread bed body is ensured to flip simultaneously during the tightening process, and the flipping angle is limited, making the flipping of the stress rods 2 more controllable. This enables the rapid tightening of the bed body, making the tightening action time-saving and labor-saving, and can be completed by a single person. In this embodiment, four stress rods 2 are provided, and the whole structure formed by the four stress rods 2 is X-shaped.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
