Description

Technical Field

[0001] This utility model relates to the field of bed technology, and in particular to a folding bed. Background Technology

[0002] Folding beds are known to be popular due to their foldability and ease of transport. However, existing folding beds, especially those with fixed legs when the user is lying down, are problematic. For example, Chinese utility model patent CN206949946U discloses a folding bed with foldable legs mounted on the frame. These legs rotate and fold together with the bed frame, allowing the bed to be moved to its storage location simply by pushing or pulling. When unfolded, the legs rotate and open. However, the U-shaped foldable legs at the foot of the bed when the user is lying down result in a small contact area with the ground, leading to instability when heavy users or multiple people are lying down (or sitting). Therefore, improvements to the existing technology are necessary. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0039] Example 1: See Figure 1 , Figure 2 and Figure 3 A folding bed includes a middle bed frame 1 and corresponding headboards 2 and footboards 3 at both ends of the middle bed frame 1. The middle bed frame 1 is pivotally connected to the headboards 2 and footboards 3, which facilitates folding and unfolding. A common bed sheet 4 is provided on the middle bed frame 1, headboards 2, and footboards 3. Mid-legs 5 are provided at both ends of the middle bed frame 1. Headboards 2 are provided with unfoldable and foldable headboards 6. Footboards 3 are provided with unfoldable and foldable stable footboards 7. The stable footboards 7 are symmetrical to each other. Distributed on the bed leg 3, the middle leg 5 is fixed and cannot be moved during use, while the headboard leg 6 unfolds and folds up first by rotating, so as to support the unfolded headboard 2 and fold it up. Since the headboard leg 6 has a larger contact area with the ground after unfolding, it will be more stable when encountering heavy bodies or multiple people lying (or sitting) in actual use, which is more conducive to meeting the user's needs.

[0040] Example 2: This can be explained based on Example 1, such as... Figure 2 and Figure 3 As shown, each stable bed leg 7 includes a movable rod 71 and a manual locking element 72 mounted on the bed leg 3. The movable rod 71 is fixedly connected to the bed leg 3 via a handle knob 73. The movable rod 71 rotates clockwise and counterclockwise around the handle knob 73. Rotating the handle knob 73 counterclockwise disengages the movable rod 71 from the bed leg 3, while rotating the handle knob 73 clockwise reconnects the movable rod 71 to the bed leg 3. The manual locking element 72 is equipped with a first connecting rod 74. The movable rod 71 and the first connecting rod 74 are connected by a support plate 75, and the support plate 75 is pivotally connected to both the movable rod 71 and the first connecting rod 74 (rotation is achieved through a movable shaft). This type of stable bed leg 7 has a simple structure, is easy to manufacture, and the corresponding support plates 75 help increase the contact area with the ground. In actual use, it is more stable when encountering heavy weights or multiple people lying down (or sitting), which better meets the user's needs. In this example, two bed legs 7 are used to stabilize the bed. This arrangement is reasonable, easy to implement, and more conducive to better supporting the bed legs 3 after they are unfolded.

[0041] Among them, such as Figures 2 to 12 As shown, the manual locking component 72 includes a fixed seat 721 mounted on the bed leg 3. The fixed seat 721 is locked to the bed leg 3 by a manual knob 722. A first internal gear ring 723 is mounted on the fixed seat 721, and a mounting seat 724 is mounted on the first connecting rod 74. A second internal gear ring 725 is mounted on the mounting seat 724. When the mounting seat 724 is placed on the fixed seat 721, the second internal gear ring 725 and the first internal gear ring 723 are on the same axis. A gear ring 726 is provided between the first internal gear ring 723 and the second internal gear ring 725, and a reset component (not shown in the figure) is provided between the gear ring 726 and the mounting seat 724. A button 727 for compressing the reset component is provided on the mounting seat 724. In the initial state, the reset component is in its original state, and the gear ring 726 is located in the fixed seat 724. Between the second internal gear ring 725 of the mounting base 724 and the first internal gear ring 723 of the fixed base 721, the gear ring 726 can mesh with both the second internal gear ring 725 and the first internal gear ring 723 respectively, preventing relative rotation between the fixed base 721 and the mounting base 724. When the button 727 is pressed, it compresses the reset component and pushes the gear ring 726 into the second internal gear ring 725 of the mounting base 724. This causes the gear ring 726 to disengage from the first internal gear ring 723 of the fixed base 721, allowing relative rotation between the fixed base 721 and the mounting base 724. When the external force of the button 727 is released, the gear ring 726 can mesh with both the second internal gear ring 725 and the first internal gear ring 723 under the spring force of the reset component, ultimately achieving stable unfolding and folding of the bed leg 7. Furthermore, the reset component uses a spring, which facilitates the reset of the gear ring 726. To further explain, the mounting base 721 is provided with an arc-shaped slot for engaging the bed leg 3, which facilitates the installation of the bed leg 3.

[0042] Among them, such as Figures 2 to 12 As shown, the handle knob 73 includes a second connecting rod 731 that connects the bed leg 3 and the movable rod 71 together. The movable rod 71 can rotate back and forth on the second connecting rod 731, and a rotating knob 732 is provided on the second connecting rod 731. By rotating the knob 732, the movable rod 71 can be locked to the bed leg 3. Further, the second connecting rod 731 is provided with a threaded section, which allows for better engagement with the rotating knob 732. That is, locking is achieved by rotating the knob 732 clockwise or counterclockwise.

[0043] Among them, such as Figure 9 , Figure 10 and Figure 11As shown, a positioning post (not shown in the figure) is provided on the fixing seat 721 at the position of the first internal gear ring 723. The positioning post allows the gear ring 726 to move along the axial direction of the positioning post, which also facilitates the installation of the reset component. Furthermore, the positioning post and the fixing seat 721 are integrally formed, which greatly improves the structural robustness and also helps reduce the difficulty of manufacturing.

[0044] Among them, such as Figure 4 As shown, the gear ring 726 is provided with a groove for installing the reset component, which facilitates the installation of the reset component.

[0045] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 1 , Figure 2 and Figure 3 As shown, both the middle support 5 and the headboard support 6 have a U-shaped structure, including two vertical tubes and a horizontal tube connecting the two vertical tubes. The ends of the vertical tubes are connected to the bed surface support frame, and the horizontal tube is used to support the ground, providing stable support. Specifically, during assembly, a support connecting rod is also connected between the middle sections of the middle support 5. Specifically, the vertical and horizontal tubes are an integrally connected structure, formed by stamping and bending a single straight tube, which is simple and efficient to manufacture. Of course, in other embodiments, it can also be composed of multiple straight tubes spliced ​​together. Furthermore, the middle support 5 and the headboard support 6 are equipped with anti-slip sleeves 8, which helps to improve the anti-slip effect.

[0046] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology, which will not be described in detail here.

[0047] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
